DEPLQUAD and DEPUQUAD: Upper and lower quadrant periodontal assessment indicators The right and left upper and lower quadrant indicators for the periodontal components were generated by the direct data entry computer program at the beginning of the examination. Therefore, indicators may be present for examinees who did not have measurements or who were edentulous. Note that because the value for the periodontal component is blank, while the quadrant indicators remained set, there will be a discrepancy between these counts. DEPOVB: Occlusal characteristics: overbite (mm) Overbite was calculated by subtraction of overlap from crown height. The exact measurement process is fully described in the Oral Examination Component manual (U.S. DHHS, 1996b). DEPPCFLG: Completion code: pocket assessment See note for DEPCJFLG.

Examinees who were completely edentulous or who otherwise have no valid or useful data have a completion code of "3 Not assessed." DEPSE1-DEPSE28: Sealants The code "2 Not eligible for sealants" was used 1) for certain teeth not shaped to hold preventive sealants and 2) for missing, crowned, or filled teeth. DEPSTCL1, DEPSTCL2, DEPSTCL3, DEPSTCL4, DEPSTCL5, DEPSTCL6: Oral soft tissue lesions: color More than one color could be indicated for each lesion. Each color is a single digit, so multiple digits indicate combinations of colors. To determine what specific colors were present, one must separate character strings into their single characters. DEPSTDX1, DEPSTDX2, DEPSTDX3, DEPSTDX4, DEPSTDX5, DEPSTDX6: Oral soft tissue lesions: clinical diagnosis The "unknown" code represents a specific diagnosis of a lesion that did not fit into any of the named categories. A lesion of "unknown" diagnosis required a clinical description. The "other" codes (46 to 59) include identifiable lesions that were different from soft tissue lesions of interest. During the examination, the dentist wrote in a diagnosis for lesions designated as "other." During data processing the 13 most frequently observed written-in conditions were grouped and coded separately (codes 47-59); the remaining rarer conditions were retained in code 46. DEPSTLC1, DEPSTLC2, DEPSTLC3, DEPSTLC4, DEPSTLC5, DEPSTLC6: Oral soft tissue lesions: locations More than one location could be indicated for each clinical diagnosis. Multiple locations are shown as combined letters and numbers. To determine what specific locations were affected, one must separate character strings into their single characters. DEPTRFLG: Completion code: traumatic injuries This variable was constructed to help the analyst decide whether or not to include an examinee with incomplete or missing data on the traumatic injuries component in the analysis of that component. For examinees who were not in the age range to receive these assessments, the traumatic injuries data and the completion code are blank. Examinees who were completely edentulous or who otherwise have no valid or useful data have a completion code of "3 Not assessed." DEPUQUAD: Upper quadrant periodontal assessment indicator See note for DEPLQUAD. ALLERGY SKIN TEST Allergy skin reactivity testing was conducted on all examinees aged 6-19 years and on a random half-sample of examinees aged 20-59 years by a trained examiner in the mobile examination center (MEC). Before skin testing, screening questions were asked to determine medical safety exclusions. Those excluded from testing were examinees who: usually did not have trouble breathing in their chest or lungs but who were having trouble breathing at the time of the examination (this trouble was NOT due to nasal congestion from a cold), usually had trouble breathing in their chest or lungs and had more trouble breathing at the time of the exam, had a severe response to allergen skin testing previously, or had severe eczema or infection on both arms. Because this examination was administered to a selected subsample in the examination center, the allergy sample weight (WTPFALG6) should be used for data analysis. For more information on the use of sample weights in NHANES III data analysis, refer to the NHANES III Analytic and Reporting Guidelines (U.S. DHHS, 1996b). The allergy skin test consisted of the evaluation of immediate hypersensitivity reactions to any of 10 licensed, commercially available, FDA-approved, standardized allergens as well as positive and negative controls. The extracts were indoor allergens (Dermatophagoides farinae (house mite), cat, German cockroach), outdoor allergens (short ragweed, perennial rye, Alternaria alternata, Bermuda grass, Russian thistle, white oak), and a food allergen (peanut). The positive control was histamine, and the negative control was the glycerinated diluent. Examiners prepared fresh allergen solutions upon arrival at each MEC site. Hypersensitivity reactions were evaluated after administering the allergens on an examinee's forearms. Allergens were applied using the prick-puncture technique at 12 skin sites (one for each allergen and the positive and negative controls) determined by a clear, plastic template. The flare and wheal areas were delineated with a marking pen 15 minutes after the skin was punctured and the allergens were applied. The length and width of the flare and wheal were measured with a 100- mm flexible, clear, plastic ruler. Length was defined as the longest diameter of the reaction, and width was defined as the diameter perpendicular to the length at its midpoint. If a reaction had any dimension 3 mm or greater, all four dimensions (length and width of flare and wheal) were measured and recorded. If all four dimensions were less than 3 mm, zeroes were recorded for all the measurements. Confluence was noted for both allergens if two reactions overlapped. For details of the allergy testing protocol, see the Training Manual for Allergy Component (U.S. DHHS, 1996b). The NHANES III allergy skin test was administered by health technicians who were trained to perform the testing. Training occurred before the examination period at special training sessions held at NCHS or at the offices of the contractor responsible for survey operations. The component was monitored on a regular basis by the component consultant, and retraining was conducted annually. In addition to data collection training, the technicians were trained to recognize and respond to generalized hypersensitivity reactions. A physician was in the MEC during all examinations, and drugs for treating systemic allergic reactions were available. Information on respiratory symptoms related to allergies can be found in the Household Adult Data File (for examinees aged 17 years and over) and the Household Youth Data File (for examinees aged 2 months-16 years). The allergen data fields are blank for examinees who were excluded for safety reasons. For those examinees who were eligible for the allergy skin test but for whom allergen data were not collected, the allergen measurement fields have "888 Blank but applicable" values. In most cases, these missing data were due to examinees not participating in the allergy skin test, usually due to time constraints. In other cases, however, data on some but not all allergens were collected. These gaps in the data were due to refusals to continue the testing or to receive specific allergens. All measurements were taken within the acceptable time of 15 plus or minus 5 minutes except for one examinee who was measured at 23 minutes after the administration of the allergens and the controls. Therefore, the variables indicating the minutes from administration to reading for each allergen were not included on this data file. Data processing and editing were performed to ensure internal data consistency.

Examiner number 1 placed the allergens, and examiner 2 measured the reactions. AUDIOMETRY Pure tone air conduction audiometric threshold testing was conducted on all examinees aged 6-19 years by a trained examiner in a soundproof room in the mobile examination center (MEC). Before threshold testing, a screening questionnaire was administered to determine the need for test exclusions and to assess factors that might affect test results. Examinees who reported having ear drainage (AUPA10) were excluded from air conduction testing on the ear(s) with drainage. Because this examination was administered in the mobile examination center, the MEC examination sample weight (WTPFEX6) should be used for data analysis. For more information on the use of sample weights in NHANES III data analysis, refer to the NHANES III Analytic and Reporting Guidelines (U.S. DHHS, 1996b). Threshold testing was conducted on both ears of examinees at seven frequencies (500, 1000, 2000, 3000, 4000, 6000, and 8000 Hertz (Hz)). The valid range for air conduction threshold values was determined by the effective range of the audiometers (Grason-Stadler, Inc., Model GSI 16, Littleton, MA), which was from -20 to 105 dumbbells (dB). Observed values were between -10 and 100 dB. If an examinee did not respond to the signal tone at any level for one or more frequencies and a comment by the examiner indicated known deafness or severe hearing loss, a threshold level of 105 dB was entered. In accordance with the testing protocol, a retest with masking occurred if an examinee had air conduction threshold value(s) at a given frequency that differed by 40 dB or more between both ears. If the lack of response was unilateral with a threshold value of 65 dB or lower for the other ear, a threshold value of 105 dB was entered for the relevant retest with masking value(s). Before the examinations began at each MEC site, a field output calibration check was performed, and an environmental noise survey was conducted. The audiometer was rechecked weekly, and during examination periods, the tone quality, masking tone quality, hearing level controls, and earphones were checked daily. If a unit did not meet specifications, it was sent for service, and a backup unit was used for examinations. Additionally, laboratory calibration on each unit was performed approximately twice a year. For details of these procedures, analysts should consult the Audiometry and Tympanometry Manual (U.S. DHHS, 1996b). Air conduction threshold testing alone is not sufficient to fully characterize hearing loss; it only provides information on the severity and the frequencies affected. Because of this, tympanic membrane compliance also was measured to help determine the nature of any hearing loss observed in the audiometry data. Analysts should refer to the Tympanometry section of the Examination Data File for information on this aspect of hearing testing. In addition, questions on hearing status including ear infection history and the use of hearing aids can be found in the Household Youth Data File (2 months- 16 years of age). The audiometry consultant provided extensive training to examiners at their time of hire, and each examiner's performance was monitored on a periodic basis. Audiometry and tympanometry were priority components at three of four annual MEC team retrainings. Data processing and editing were performed to ensure internal data consistency. Notes have been provided for variables requiring additional explanation.

III Examination Data File ------------------------------------------------------------------------ THIS PAGE INTENTIONALLY LEFT BLANK NOTES AUPA10: Drainage/discharge from either ear? Examinees who reported having ear drainage were excluded from air conduction testing on the ear with drainage and from tympanic membrane compliance testing on both ears. Threshold value fields for excluded ears are blank. Tympanometry data fields for excluded examinees are blank. AUPA9: Tube in right or left ear? Examinees who reported having a tube in either or both ears were excluded from tympanic membrane compliance testing. However, air conduction threshold testing was performed if there was no report or evidence of drainage (AUPA10). Tympanometry data fields for excluded examinees are blank. AUPAUDO2 and AUPB1C1-AUPB1C8, AUPB2C1-AUPB2C8: Retest information When examinees had air conduction threshold values at a given frequency that differed by 40 dB or more between the left and right ears, the ear with the higher threshold value(s) was retested while a masking sound was introduced into the other ear. In cases for which a retest was indicated but for which no retest data existed, the relevant variables were coded "Blank but applicable." If no threshold value differences of 40 dB or more were observed, these variables are blank. TYMPANOMETRY Tympanic membrane compliance was tested for all examinees aged 6-19 years by a trained examiner in a soundproof room in the mobile examination center (MEC). A screening questionnaire administered before audiometry testing also determined tympanometry test exclusions and can be used to assess factors that might have affected tympanometry results. If an examinee reported that either ear had a tube (AUPA9) or drainage (AUPA10), tympanometry was not performed, and all tympanometry variables are blank. Analysts should refer to the Audiometry section of the examination data file for information on the screening questionnaire. In addition, questions on hearing status, including ear infection history and the use of hearing aids, can be found in the Household Youth Data File (ages 2 months-16 years). Because this examination was administered in the mobile examination center, the MEC examination sample weight (WTPFEX6) should be used for data analysis. For more information on the use of sample weights in NHANES III data analysis, refer to the NHANES III Analytic and Reporting Guidelines (U.S. DHHS, 1996b). The tympanometer (Model TA-7A Automatic Impedance Meter, Teledyne Avionics, Charlottesville, VA) produced a paper tympanogram output and was connected to a personal computer for electronic data collection. Tympanometer function was checked daily. If a unit did not meet specifications, it was sent for service, and a backup unit was used for examinations. Laboratory calibration on each unit was performed approximately twice a year. For details of equipment maintenance procedures, analysts should consult the Audiometry and Tympanometry Manual (U.S. DHHS, 1996b). Training for tympanometry was combined with that for audiometry. At the time of hire, examiners received extensive instruction from the audiometry consultant, and the examiners' performance was monitored on a periodic basis. Hearing evaluation, which included audiometry and tympanometry, was a priority component at three of four annual MEC team retrainings. The variables containing equivalent volume at various pressures (TYPC000L-TYPC120L, TYPC000R-TYPC120R) can be used to create tympanogram plots of compliance as a function of pressure. To do so, the analyst must rearrange the data to have 121 observations per examinee (one for each pressure value at which compliance was determined from -400 to 200 daPa in 5 daPa increments) and create a variable to record the associated pressure values. An example of SAS programming code to perform this rearrangement is included in the note for TYPC000L-TYPC120L and TYPC000R-TYPC120R. This data file includes 242 variables with equivalent volume data for pressure values between -400 and 200 daPa. Many examinees have data for pressure values of -200 daPa or greater but have no data (blanks) for pressure values from -400 to -205 daPa. This is due to variability in a software setting on the tympanometer that toggled an option for continuing readings to -400 daPa or stopping the pressure at -200 daPa if a compliance peak occurred before -175 daPa. There are data for pressures between -400 and -205 daPa for 1156 left ear observations and 1166 right ear observations. Of these observations with data for pressures lower than -200 daPa, only 192 left ear observations and 200 right ear observations had pressure at peak compliance values of -175 daPa or lower. When plotting tympanogram data, analysts may want to include data points for pressure values between -400 and -205 daPa. However, in most cases, this pressure range will not add useful tympanogram information. Early in the survey, electronic data collection was not fully operational, and sporadic equipment problems led to data loss throughout the survey. In these cases, the tympanogram data points (TYPC000L-TYPC120L, TYPC000R-TYPC120R) are not available. However, the values for peak compliance (TYPCMPLL, TYPCMPLR), pressure at peak compliance (TYPPRSPL, TYPPRSPR), canal volume (TYPVOLL, TYPVOLR), and acoustic reflex (TYPRFXL, TYPRFXR) were entered into the data from the hard copy tympanograms if they were available. Data processing and editing were performed to ensure internal consistency of data. Notes have been provided for variables requiring additional explanation.

This represents a variation from the usual NHANES test protocol, in which tests are conducted based on the age at the time of the household interview, rather than on the age at the time of the MEC examination. The protocol for this component did not detail any medical, safety or other exclusions. Because these tests were administered in the mobile examination center (MEC), the MEC examination sample weight (WTPFEX6) should be used for data analysis. For more information on the use of sample weights in NHANES III data analysis, refer to the NHANES III Analytic and Reporting Guidelines (U.S. DHHS, 1996b). Cognitive function was evaluated using parts of two tests, the Wechsler Intelligence Scale for Children-Revised (WISC-R) and the Wide Range Achievement Test-Revised (WRAT-R). Two subtests of the WISC-R test, a verbal component (Digit Span) and a performance exam (Block Design), were administered and are considered relatively culturally unbiased (Kaufman, 1979). In addition, two subtests of the WRAT-R test, math and reading, were conducted. The WISC-R test was administered first and was followed by the WRAT-R. The scores for all four subtests used a common scale and were derived for each child relative to his/her age group based on test-specific standardization samples created by the test developers (Wechsler, 1974; Jastak, 1984; Kramer, 1995). At the time of hire, MEC interviewers were trained to conduct the WISC/WRAT examination. During annual site visits, test administration was evaluated, and re-training took place. To increase the number of evaluated examination administrations with minimum intrusion and after obtaining informed consent from the examinees or their guardians, sessions were audio-taped and reviewed for protocol adherence. Feedback was provided to the interviewers after review of the taped sessions. An automated data collection system ensured that responses obtained were within acceptable ranges. Consequently, minimal data processing and editing were required. Notes have been provided for standardized and recoded variables and for variables requiring additional explanation. Conducting only a portion of each of the WISC-R and WRAT-R tests with children in NHANES III limits data interpretation. For example, an Intelligence Quotient (IQ) cannot be calculated for an individual using the WISC-R results from NHANES III because only certain subtests were administered. The complete WISC-R examination is comprised of twelve components, six verbal and six performance modules. An IQ can be calculated only when ten of the twelve verbal and performance elements are administered. Similarly, the WRAT-R test administered in NHANES III omitted a spelling section and is, therefore, incomplete. For additional information on the tests, refer to the Manual for the Wechsler Intelligence Scale for Children-Revised (Wechsler, 1974) and the Wide Range Achievement Test-Revised Administration Manual (Jastak, 1984).

This variable represents the scaled score for the reading test and allows comparison between the WRAT-R and WISC-R exams. WWPRSSR: Reading standardized score See note for WWPMSSR. SPIROMETRY Lung function testing (spirometry) was conducted on examinees aged eight years and older by a trained technician in the mobile examination center (MEC). It also was conducted at the home of examinees aged 60 and over who were unwilling or unable to come to the MEC. Before testing, screening questions were asked to determine medical safety exclusions. Those excluded from testing were examinees who had undergone chest or abdominal surgery within three weeks or had experienced heart problems (myocardial infarction or heart attack, angina or chest pain, congestive heart failure) within six weeks before the MEC exam. To determine which subjects were home examinees, the DMPSTAT variable (3=home-examined) should be used. When analyzing data for combined home-examined and MEC-examined subjects, the combined MEC- plus home-examined sample weights should be used (WTPFHX6). When using only MEC items or measures, the MEC examination sample weights should be used (WTPFEX6). For more information on the use of sample weights in NHANES III data analysis, refer to the Analytic and Reporting Guidelines (U.S. DHHS, 1996b). Spirometry is a widely used test of lung function that measures both the volume of air in the lung and how quickly a person can move the air out of the lung. A testing session consisted of repeated forced vital capacity (FVC) maneuvers. Each maneuver required the examinee to take the deepest possible breath and exhale into a spirometer as hard, fast, and completely as possible. The spirometer recorded the volume of air exhaled as a function of time from which a number of parameters were measured. Each examinee attempted to perform at least five FVC maneuvers. The testing procedure was explained and demonstrated to each examinee by a spirometry technician. The computer provided immediate feedback on the examinee's effort, and the technician used that information to actively coach the examinee through each trial. For a maneuver to be acceptable, it had to be a maximal exhalation free from a cough, excessive hesitation, a leak, an obstructed mouthpiece, variable effort, or early termination. An additional goal was that the examinee have a sufficient number of trials to demonstrate that the FVC and forced expiratory volume(FEV1) values were reproducible. Aside from using a different type of spirometer flow-type (see SPPTYPE) in home examinations, technicians used procedures comparable to those used in the MEC. Therefore, the home spirometry values were incorporated into the MEC spirometry measures data set. Refer to the Spirometry Examination Manual (U.S. DHHS, 1996b) and the Home Exam Manual (U.S. DHHS, 1996b) for descriptions of data collection procedures and methods. Testing procedures met the recommendations of the American Thoracic Society (American Thoracic Society, 1987). The National Institute for Occupational Safety and Health (NIOSH) served as the spirometry quality control center. Each spirometry technician received at least one week of formal training and satisfactorily completed a NIOSH-approved course on spirometry. Additionally, spirometry data were reviewed by the quality control center at the completion of each location, and technicians received continuous feedback on their performance. Data processing and editing were performed to ensure internal data consistency. Notes have been provided for variables requiring additional explanation.

SPPFEF75: Flow at 75% of FVC (ml/second) This was the flow rate (ml/second) at 75% of the FVC. Values were obtained from the "best curve" or the curve with the largest sum of FEV1 plus FVC. SPPFEV05: Forced expiratory volume (FEV) at 0.5 seconds (ml) The volume (ml) of air exhaled during the first 0.5 second of a forced vital capacity maneuver. The volume reported is the largest volume achieved from all acceptable FVC maneuvers. SPPFEV1: Forced expiratory volume at 1 second (ml) The volume (ml) of air exhaled during the first second of a forced vital capacity maneuver. The volume reported is the largest volume achieved from all acceptable FVC maneuvers. SPPFEV3: Forced expiratory volume at 3 seconds (ml) The volume (ml) of air exhaled during the first three seconds of a forced vital capacity maneuver. The volume reported is the largest volume achieved from all acceptable FVC maneuvers. SPPFEV6: Forced expiratory volume at six seconds (ml) The volume (ml) of air exhaled during the first six seconds of a forced vital capacity maneuver. The volume reported is the largest volume achieved from all acceptable FVC maneuvers. SPPFVC: Forced vital capacity, largest value (ml) The total volume (ml) of air exhaled during a forced vital capacity maneuver. The volume reported is the largest volume achieved from all acceptable FVC maneuvers. SPPMANEU: Number of acceptable trials The number of FVC maneuvers that met the ATS acceptability criteria. SPPMMEF: Maximum mid-expiratory flow (ml/second best curve) The mean forced expiratory flow during the middle half of the FVC maneuver. Values were obtained from the "best curve" defined as the curve with the highest sum of FVC and FEV1. SPPPEAK: Peak expiratory flow (ml/second) The maximum expiratory flow (ml/sec) observed from all acceptable FVC maneuvers. SPPRELIA: Test evaluation All tests were reviewed by two senior quality technicians at the spirometry quality control center and classified for reliability. Tests deemed unreliable should not be used because the quality technicians determined that the results were of insufficient quality to be usable. SPPREPRO: Reproducibility code In accordance with ATS guidelines, all unacceptable maneuvers were excluded before the reproducibility calculations were performed. The goal during test performance was to obtain a reproducible FVC (largest FVC and second largest FVC within 5%) and a reproducible FEV1 (largest FEV1 and second largest FEV1 within 5%). The reproducibility code indicates whether a reproducible FVC and/or FEV1 was obtained. SPPTEMP: Spirometer internal temperature (Celsius) This was the internal temperature inside the spirometer measured at the end of the FVC maneuver. SPPTRIAL: Number of forced vital capacity (FVC) trials attempted This was the total number of forced vital capacity maneuvers attempted by the sample person. SPPTYPE: Spirometer type Four different types of spirometers were used; one type was used in MEC spirometry exams, and three different types were used in home spirometry exams. The MEC spirometers (type=1) were customized, Ohio 822 or 827, dry, rolling-seal spirometers and were interfaced to a microcomputer. For home spirometry, the three types of flow spirometers used were: MultiSpiro (type=2), Riko model AS-600 (type=3), and NIOSH (type=4). The MultiSpiro- and Riko-brand spirometers produced paper tracings with digital readings of FVC and FEV1. These spirometers provided neither quality assessments of the subject's effort nor some of the spirometry variables measured in the MEC. The NIOSH flow spirometer measured all of the parameters measured by the MEC spirometer and provided a display of the subject's flow-volume curve with a computer-determined quality assessment equivalent to the assessment provided by the spirometer used in the MEC. MEC YOUTH QUESTIONNAIRE (Except DIS) The MEC Youth Questionnaire was administered to examinees aged 8-16 years in the mobile examination center (MEC). Conducted by a trained interviewer, the automated questionnaire was administered in a private setting to ensure confidentiality due to the sensitive nature of some of the sections. The questionnaire included sections on physical activity, tobacco use, reproductive health, selected conditions, medicine/vitamin usage, food frequency, alcohol/drug use, and the Diagnostic Interview Schedule (DIS). Because this component was administered in the examination center, the MEC examination sample weight (WTPFEX6) should be used for data analysis. For more information on the use of sample weights in NHANES III data analysis, refer to the NHANES III Analytic and Reporting Guidelines (U.S. DHHS, 1996b). Several portions of the questionnaire were asked only of specific age or gender groups, and check items are included as variables in this file to indicate these subgroups. For example, reproductive health was asked of boys aged 15-16 years and girls aged 10-16 years. Medicine/vitamin use, food frequency, and alcohol/drug use were asked of boys and girls aged 12-16 years. The DIS was asked of adolescents aged 15-16 years. The DIS was edited and documented separately (see Diagnostic Interview Schedule). A subset of questions from the MEC Youth Questionnaire were administered as the MEC Proxy Questionnaire to the parents or guardians of children aged 2 months-11 years. Questions on medicine, vitamin, and mineral usage, selected health conditions, and WIC program participation from the two questionnaires can be combined for an analysis of youths 2 months-16 years of age (see MEC Proxy Questionnaire). Data processing and editing were performed for consistency of responses within the sections of the questionnaire. Notes have been provided for variables that were standardized or recoded or those that require additional comments. The notes reference the questions, by section and number, from the questionnaires which can be found in the Plan and Operation of the National Health and Nutrition Examination Survey, 1988-1994 (NCHS, 1994; U.S. DHHS, 1996b).

The actual number of cigarettes smoked per day and a range of cigarettes smoked per day were the allowable answers. The variable includes the mean number of cigarettes smoked per day derived from the range as well as the actual number of cigarettes smoked per day. MYPB7R: Years smoked this amount in MYPB6R This variable was created from the question B7 when the data were not missing. If B7 was missing, this variable used the estimated number of years the respondent smoked the amount reported in B6. The number was derived by subtracting the age that the respondent started smoking regularly from the age at the MEC interview. MYPB9S: Number of cigarettes per day when smoked the most This variable was created from the two-part question (quantity and unit) B9 using the conversion factor 20 cigarettes/pack. MYPB13S: Number of cigarettes per day usually smoked when youth smoked regularly This variable was created from the two-part question (quantity and unit) B13 using the conversion factor 20 cigarettes/pack. MYPB21AS: Number of containers of chewing tobacco used per week This variable was created from the two-part question (quantity and unit) B21 using the conversion factor seven containers/week. MYPB21CS: Number of containers of snuff used per week This variable was created from the two-part question (quantity and unit) B21 using the conversion factor seven containers/week. MYPC7S: Months since stopped taking birth control pills This variable was created from the two-part question (quantity and unit) C7 using the conversion factor 12 months/year. MYPC8S: Total number of months took birth control pills This variable was created from the two-part question (quantity and unit) C8 using the conversion factor 12 months/year. MYPC9R: Birth control pills codes This recode was derived to include a listing of all birth control pills that were specified in question C9. It includes both birth control pills with original codes from the chart that the respondents were shown as well as those that were not included on the chart but that were specified by the respondents. See the Appendix in the MEC Adult Questionnaire for the code listing. MYPC13R: Age at time of first live birth Question C13 (age at time of first live birth) was only asked of women who had more than one live birth. To prevent redundant questions, women who had one live birth were only asked question C14, "Age at the time of the last live birth." This variable, MYPC13R, was created to include responses for women who had only one live birth and women who had multiple births. For women who had only one live birth, their responses to question C14 were coded into MYPC13R. For women who had multiple births, their responses to question C13 were coded into MYPC13R. MYPC23S: Number of months received WIC benefits This variable was created from the two-part question (quantity and unit) C23 using the conversion factor 12 months/year. MYPC27R: Ever had sexual intercourse This variable was derived from questions C10 and C27. Respondents who reported a pregnancy (question C10) were not asked whether they had ever had sexual intercourse (question C27) as the response was implicit. Therefore, MYPC27R was coded as "Yes" for respondents who reported a pregnancy in C10 and coded as the response in C27 for all other respondents. MYPC28: Age at first sexual intercourse The question did not ask about first consensual sexual experience. Therefore, responses of first intercourse at very young ages were retained after reviewing comments made during the interview (e.g., reports of rape or incest). MYPF3S: Number of days drank alcohol in past year This variable was created from the two-part question (quantity and unit) F3 using the conversion factors 7 days/week, 30.4 days/ month, and 365 days/year. MYPF5S: Number of days drank nine or more drinks of alcohol in past year This variable was created from the two-part question (quantity and unit) F5 using the conversion factors 7 days/week, 30.4 days/month, and 365 days/year. MYPF6S: Number of days drank five or more drinks of alcohol in past year This variable was created from the two-part question (quantity and unit) F6 using the conversion factors 7 days/week, 30.4 days/month, and 365 days/year. DIETARY FOOD FREQUENCY QUESTIONNAIRE (AGES 12-16 YEARS) The Dietary Food Frequency questionnaire was administered to youths aged 12-16 years in the mobile examination center (MEC). Respondents were asked how often over the past month they had eaten specified food items. The foods were listed in groups, targeting those high in vitamins A and C and calcium. Respondents reported their consumption as the number of times per day, per week, per month, or never. It is important to note that portion sizes were not defined, and responses represent "number or times" as determined by the respondent. The questionnaire was identical to the food frequency section of the Household Adult Questionnaire administered to adults aged 17 years and above (see Adult Household Data File). MEC examination weights (WTPFEX6) should be used for analysis of the youth Dietary Food Frequency (Ages 12-16 years). The interview weights (WTPFQX6), however, should be used when analyzing the adult food frequency data. For more information on the use of sample weights in NHANES III data analysis, refer to the NHANES III Analytic and Reporting Guidelines (U.S. DHHS, 1996b). Data processing and editing were performed for consistency of responses within the sections of the questionnaire. As part of the editing process, the frequency of consumption of food items was standardized to the number of times consumed per month. Notes have been provided for variables that were standardized or recoded or that require additional comments.

If the frequency of consumption was reported as "never," the value was recorded as zero. FFP1D1: Usual type of milk consumed Only usual milk consumed was recorded here. If more than one milk type was reported as "usual," the first milk reported was recorded. Guidelines based on fat content were developed in order to recode other milks that were reported but not listed and to create new categories. Codes/recodes Reported usual milk 01 (whole/regular milk) goat's milk 02 (2%/low fat) 03 (1% milk) acidophilus milk; lactose-reduced milk 04 (skim/nonfat milk) hot chocolate mix; powdered milk; 0.5% milk 05 (buttermilk) 06 (evaporated) 07 (other not specified) 11 half and half/cream FFP8AFC: New codes for other foods not listed Respondents also were asked about other foods not listed in the food frequency questionnaire. Responses to this question from both the adult and the youth food frequency questionnaires were edited by first determining whether the food could be coded back into an existing category. When possible, the frequency of consumption of that food was added to the original response for the pre-existing category. If the original response was "Never consumed," then the consumption frequency for the "Other food not listed" replaced the original response. Foods that were reported using frequency units were first converted to a common unit; the frequencies were summed to produce whole number estimates. For example, if the reported frequency for the category "Other vegetables" was once per day and asparagus consumption once per week was reported for "other food not listed," then the frequency for asparagus consumption was added to the frequency of the "Other vegetables" category and recalculated as a consumption of eight per week. When it was not possible to recode a response, a determination was made about whether a new category should be created based on the reported frequency of the food or whether the food represented an important source of a specific nutrient. The following eight new food groups were defined: 01 Egg substitutes 02 Decaffeinated coffee and espresso 03 Decaffeinated/herbal tea 04 Sports drinks, fruit drinks (excluding juices but including tamarind drinks), and popsicles 05 Water, including tap, mineral, spring, seltzer, soda 06 Soy products, including tofu, soy milk, soy ice cream, soy cheese, soy hamburgers, soy hot dogs, soy flour, and textured vegetable protein 07 Non-alcoholic beer/wine 08 Others not specified or not elsewhere classified, including diet, breakfast, and nutrition drinks, pudding, condiments, sour or whipped cream, granola bars, and gelatin DIAGNOSTIC INTERVIEW SCHEDULE (DIS) The mental health component of NHANES III included the depression and mania modules from the Diagnostic Interview Schedule (DIS) originally developed for the National Institute of Mental Health (NIMH) Epidemiologic Catchment Area (ECA) program. Trained interviewers administered the NHANES III DIS questions in the MEC, using automated data entry, as part of the MEC Youth Questionnaire for examinees 15-16 years of age and as part of the MEC Adult Questionnaire for examinees 17-39 years of age. The data from the DIS permit diagnoses based on the third edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM- III). The final MEC examination weight (MTPFEX6) should be used for analysis of the questionnaires and measurements administered in the MEC, as well as for a combined analysis of measurements from the MEC examinations and associated medical history questions from the household interview. The household questionnaire data files include information on survey design and basic demographic variables which may be linked to the examination data file by using the unique survey participant identifier SEQN. For more information on the use of sample weights in NHANES III data analysis, refer to the NHANES III Analytic and Reporting Guidelines (U.S. DHHS, 1996b). The DIS is a complicated questionnaire with a number of parallel series of questions and many skip instructions. The notes below describe these question series and skip patterns, and analysts are instructed to carefully read these notes in their entirety in order to facilitate analysis of this data. The Plan and Operation of the Third National Health and Nutrition Examination Survey, 1988-94, page 362, (NCHS, 1994; U.S. DHHS, 1996b) contains a flow chart of the probe questions and skips from the DIS. All variable names in the DIS portion of the MEC interviews start with the prefix MQP. The M indicates that it came from the MEC interview, the Q indicates that the data transcend the boundaries of separate adult (A) and youth (Y) interviews (sample persons ranged from ages 15-39) and the P indicates the data came from the primary interview. Any sample person who was age 15 to 39 was eligible to receive this section of the adult or youth MEC questionnaire. A sample person who was not eligible to receive this section of the questionnaire will have all blanks in this section. Note that selected questions may be blank in the DIS section if the question was not applicable for the sample person to answer because of answers they had given to other questions. Also note that many of the questions have combined the "Don't know" and "No" category into a single response and this combination will vary per question in the DIS section. Approximately 3.7% (322/8773) of the NHANES III sample did not have valid depression and mania sections of the questionnaire, with an additional 18 or 0.2% missing all or part of one section or the other. The major reasons for these missing data are that respondents: 1) ran out of time, 2) felt the material was too sensitive, usually because they were using an interpreter, 3) had comprehension problems due to cognitive impairment, 4) primary language was not English or Spanish, or 5) refused to answer or were not asked critical questions. All of the questions for these sample persons were coded "Blank but applicable."

There were 41 adults and 32 youth where this change was made in the study. Most Hispanic youth spoke English fluently enough that a Spanish translation was not necessary, therefore, no computerized version of the youth interview was available in Spanish. It was only given on hard copy. MQPDLANG was set to 4, Spanish Youth, only if the variable DMAETHNR was greater than or equal to 3 and MQPLANG was equal to 3, and the examination was given on hard copy (MQPHCFLG=1) or a specific comment was made that indicates the interview was given in Spanish. MQPDPFLG, MQPMNFLG: Depression and mania completeness flags When a code of "1" is given to the depression (MQPDPFLG) or mania (MQPMNFLG) completeness flag, the respondent only answered the lifetime symptom questions (16 for depression and 9 for mania) and any appropriate probe questions. It was then determined in MQPG21, a check item, that there were not enough positive symptom groups to continue asking questions (MQPG21=3 or MQPG50=3 for depression and mania, respectively). The diagnosis of major depressive episode (MQPDEP) or manic episode (MQPMANIA), respectively, is set to "No." When a code of "2" is given to the depression (MQPDPFLG) or mania (MQPMNFLG) completeness flag, the respondent answered not only the lifetime symptom questions (16 for depression and 9 for mania) and any appropriate probe questions but also one or more of the questions concerning clustering of the positive symptom groups. These sample persons can skip out of the section at several different points, but they never answer questions past MQPG26 or MQPG55, respectively, and they cannot have a positive diagnosis for major depressive episode (MQPDEP) or manic episode (MQPMANIA). The diagnosis of major depressive episode or manic episode, respectively, is set to "No." When a code of "3" is given to the depression (MQPDPFLG) or mania (MQPMNFLG) completeness flag, the respondent answered not only the lifetime symptom questions (16 for depression and 9 for mania) and any appropriate probe questions but also all the questions concerning clustering of the positive symptom groups and the worst episode. These sample persons should have answers to all questions in their respective sections and have the chance for a positive diagnosis for major depressive episode (MQPDEP) or manic episode (MQPMANIA). The diagnosis of major depressive episode ranges from 1-5 and the diagnosis of manic episode ranges from 1-3. When a code of "4" is given, the lifetime symptoms were completed and the sample person met criteria to continue answering questions (MQPG21=1 or 2), but the remaining section of questions needed to make a diagnosis were not ascertained (blank, but applicable) or were all answered "don't know." This is not the same as MQPG21=3 or MQPDPFLG=1 where sample persons only answered the lifetime symptom questions because they did not have enough positive symptoms to qualify to answer the remaining questions. When a code of "5" is given, the depression and/or mania section should have been given, but was not, so all fields are filled with 8's (blank but applicable). Lastly, a blank in this field indicates the sample person was not in the acceptable age range and was not eligible for the depression or mania questions. In short, the flags divide the data into five groups: 1. Lifetime symptoms answered, insufficient number positive to ask clustering questions 2. Sufficient lifetime symptoms present but do not cluster in spells of sufficient duration 3. Sufficient lifetime symptoms present and cluster in spells of sufficient duration, and may or may not meet criteria for positive diagnosis 4. Sufficient lifetime symptoms present but no information available if cluster in spells of sufficient duration - missing diagnosis 5. No information available, but should have been collected - missing diagnosis Blank values appear where the DIS not applicable. MQPHCFLG: Hard copy flag Although in almost all circumstances the DIS section of the interview was given using the computerized version, there were certain situations where a paper copy was used. This would occur only when there was a computer failure or for youth who required a Spanish version. These interviews are considered valid, but responses to probe questions were not recorded, and are therefore set to 8's (blank but applicable). MQPG0501-MQPG1301, MQPG05L-MQPG12L, MQPG1501-MQPG1601, MQPG14L-MQPG20L: Lifetime symptoms of depression The questionnaire inquires whether a symptom has occurred at any time in life (G5-G20). Each of these DIS symptom questions can take a value of "1-4." The value "2" means the respondent said "No" or "Don't know." If the respondent said "Yes," additional "probe" questions were asked. First, the respondent was asked if they told a doctor about the symptom. The answer to this probe question is included after each respective lifetime symptom. When the interview was given on hard copy (i.e., not by computer - See MQPHCFLG, a flag for hard copy), no probe questions were recorded so the probe questions are filled with 8's (blank but applicable). The respondent was then asked if the symptom was always due to a physical illness or injury (this included pregnancy). If the respondent said "Yes," then a "4" was coded. If the respondent said "No," then he/she was next asked whether the symptom always occurred when he/she used medicine, alcohol, or drugs. If the respondent said "Yes," then a "3" was coded. If the respondent said "No," then a "1" was coded. A value of "1" indicates that the possibility of this being a symptom of a mental disorder cannot be ruled out. Additional probes were asked for G13. (See notes for MQPG1302-MQPG1304.) As a word of caution, in the Spanish version of question G8, "Have you ever had a period of two weeks or more when you had trouble falling asleep, staying asleep, or with waking up too early?," the phrase used for "falling asleep" really meant "staying asleep" rather than what was intended. Still another phrase was used for the part of the question "staying asleep." Consequently, "staying asleep" was well covered and "falling asleep" was not. There is no way to tell to what extent this affected the number of positive responses. MQPDGP1L-MQPDGP8L: Summary questions The lifetime depressive symptom questions (G5-G20) are arranged in eight groups, each of which approximates one of the diagnostic criteria in Section B of the definition of a major depressive episode from the American Psychiatric Association's Diagnostic and Statistical Manual, Third Edition (DSM-III). MQPDGP1L- MQPDGP8L are the eight summary variables which indicate the number of positive (1's) lifetime symptoms in each of the respective groups. MQPG13L, MQPG1302-MQPG1304: Decreased interest in sex If the respondent answered "Yes" to the initial question (G13: decreased interest in sex), a series of additional questions was asked (MQPG1302- MQPG1304). If the respondent answered "No" to all three questions, then a code "6" (yes, but wasn't bothered) was entered for G13, indicating that the symptom was below the diagnostic threshold. If the respondent answered "Yes" to any one of these three additional questions, then the normal "probe" questions were asked, leading to an assignment of values 1, 3, 4, that is, whether the symptom was always due to physical illness or injury or medicine, alcohol, or drugs; any remaining parts of MQPG1302-MQPG1304 were skipped after a "Yes" response to any one of the probes. If the respondent volunteered that he/she had never been interested in sex, the value "5" (no interest ever) was coded. MQPG21-MQPG25: Depression module decision points Item G21 asks the interviewer whether three or more summary groups of the possible eight had at least one "Yes" response coded. If there were fewer than three, all the remaining DIS depression questions were skipped and the interviewer moved to the mania questions (G41-G49). If a respondent had three or more DSM-III symptoms during his/her life (G21), the interviewer asked one of two parallel series of questions to determine whether questions pertaining to the worst depressive episode should be asked. The series of questions are explained below: Series A, Questions G22, G23, and G26: G21 was coded "1" if there were three or more depressive symptoms and the respondent answered "Yes" to the initial question (G2) about two weeks or more of feeling sad, blue, or depressed. The respondent was then asked G22 about having these problems cluster in time, in the same month. If the answer was "Yes," G26 was asked. If the response to G22 was "No" (meaning the problems did not cluster in the same month), then a second question about temporal clustering was asked (G23). If the respondent again denied having problems cluster ("Yes, never been a period"), the remaining depression questions were skipped and the interviewer moved on to the mania questions. If the respondent said "No, has been a period" to G23, then G26 was asked. Series B Questions G24, G25, and G26: G21 was coded "2" if there were three or more depressive symptoms and the respondent answered "No" to the initial question (G2) about ever having had two weeks or more of feeling sad, blue, or depressed. G24 was then asked to determine if several of the depressive symptoms (G5-G20) were clustered together in the same month. If the answer to this was "No," then the remaining DIS depression questions were skipped and the interviewer moved on to the mania questions. If the answer was "Yes" then G25 was asked, which elicits symptoms of "masked depression." If the respondent indicated that he/she felt "low, gloomy, blue, or uninterested" then he/she was asked G26. If the respondent indicated that he/she felt "okay," the remaining DIS depression questions were skipped and the interviewer moved on to the mania questions. MQPG05W-MQPG20W: Worst episode depressive symptoms These questions ask about symptoms during the worst episode identified in G40. Each of the questions about a worst depressive episode is parallel to one of the lifetime depression questions: for example, MQPG05L asks "has there ever been a period of two weeks or longer when you lost your appetite?" The corresponding worst episode question, MQPG05W, asks, "Did you lose your appetite?" The worst episode question (in this example, MQPG05W) was only asked if the corresponding lifetime question (in this example, MQPG05L) was coded "1." The worst episode question was coded "Yes" or "No," indicating the presence or absence of the symptom during the worst depressive episode. A diagnosis of major depressive episode was based on the symptoms during the worst depressive episode (MQPG05W-MQPG20W) which are transformed into eight DSM-III symptom groups (MQPDGP1W-MQPDGP8W), and is not based on the lifetime depressive symptoms (MQPG05L-MQPG20L). MQPG41L-MQPG49L: Lifetime symptoms of mania The questionnaire inquires about whether a symptom has occurred at any time in life (G41-G49). Each of these (DIS) symptom questions can take a value of "1-3." The value "2" means the respondent said "No" or "don't know." If the respondent said "Yes," two additional "probe" questions were asked. The respondent was asked whether the symptom ever occurred when he/she used medicine, alcohol, or drugs. If the respondent said "Yes," then he/she was next asked whether the symptom always occurred when he/she used medicine, alcohol, or drugs. If the respondent said "Yes," then a "3" was coded. If the respondent said "No" to either question, than a "1" was coded. A value of "1" indicates that the possibility of this being a symptom of a mental disorder cannot be ruled out. When the interview was given on hard copy (i.e., not by computer - See MQPHCFLG, a flag for hard copy), responses to probe questions were not recorded so the probe questions are filled with 8's (blank but applicable). MQPG47EX: Examples of special gift or power If the respondent answered "Yes" to G47L, possessing a special gift or power, they were asked for an example. Since a high percentage of the examples given had to do with extra sensory perception (ESP), it was decided to code these examples into two categories, ESP and other. There were not enough examples with similar characteristics to code any other group. The query regarding special gifts or powers is intended to elicit reports of beliefs about the self which are psychotic in nature. If the example did not meet this precept, the symptom (MQPG47L) was coded "No" and the example deleted. MQPG50-MQPG54: Mania module decision points Item G50 asks the interviewer whether two or more lifetime symptoms of the possible eight (MQPG42L- MQPG49L) had at least one response of "1" coded. If there was a "Yes" response of one or less lifetime symptoms, all the remaining mania questions were skipped and the interviewer moved to the next section. The remaining DIS questions were coded as blank. If a respondent had two or more DSM-III symptoms during his/her life, the interviewer asked one of three parallel series of questions to determine whether questions pertaining to the worst episode of mania should be asked or possibly skipped to the next section. The three series are explained below: Series A, Questions G51, G52, and G55: G50 was coded "1" if there were two or more symptoms of mania and the respondent answered "Yes" to the initial question (G41) about one week or more of feeling high or manic. The respondent was then asked G51 about having these problems cluster in time, in the same month. If the answer was "Yes," G55 was asked. If the response to G51 was "No" (meaning the problems did not cluster in the same month), then a second question about temporal clustering was asked (G52). If the respondent again denied having problems cluster ("Yes, never been a period"), the remaining mania questions were skipped and the interviewer moved on to the next section. If the respondent said "No, has been a period" to G52, G55 was asked. Series B, Questions G53-G55: G50 was coded "2" if there were three or more symptoms of mania and the respondent answered "No" or "Always due to medication/drugs/alcohol" to the initial question (G41) about ever having had one week or more of feeling high or manic. G53 was then asked to determine if several of the depressive symptoms (G42-G49) were clustered together in the same month. If the answer to this was "No," then the remaining DIS mania questions were skipped and the interviewer moved on to the next section. If the answer was "Yes" then G54 was asked, which elicits symptoms of irritable mood. If the respondent indicated that he/she felt "unusually irritable or likely to fight or argue" then he/she was asked G55. If the respondent indicated that he/she never felt irritable, the remaining DIS mania questions were skipped and the interviewer moved on to the next section. Series C: G50 was coded "3" if: 1) there were only two symptoms of mania coded "1" and the respondent answered "No" or "Always due to medication/drugs/alcohol" to the initial question (G41) about ever having had one week or more of feeling high or manic, i.e., responses "2" or "3;" or, 2)there was only one or less symptoms of mania coded "1." With these combinations, the remaining DIS mania questions were skipped and the interviewer moved on to the next section. MQPG42W-MQPG49W: Worst episode symptoms of mania These questions ask about symptoms during the worst episode of mania identified in G66. Each of the questions about a worst episode of mania is parallel to one of the lifetime mania questions: for example, MQPG42L asks "has there ever been a period of a week or more when you were so much more active than usual that you or your family or friends were concerned about it?" The corresponding worst episode question, MQPG42W, asks, "Were you so much more active than usual that you or your family or friends were concerned about it?" The worst episode question (in this example, MQPG42W) was only asked if the corresponding lifetime question (in this example, MQPG42L) was coded "1." The worst episode question was coded "Yes" or "No," indicating the presence or absence of the symptom during the worst episode of mania. A diagnosis of manic episode was based on the symptoms during the worst episode of mania MQPG42W- MQPG49W) which were transformed into seven DSM-III symptom groups (MQPMNG1W-MQPMNG7W), and is not based on the lifetime symptoms of mania (MQPG42L- MQPG49L). MQPDGP1W-MQPDGP8W, MQPDYSFR, MQPDEP: The diagnostic variable "MQPDEP" The variable MQPDEP indicates the diagnosis of major depressive episode which is based on Criteria A and B of the DSM-III definition of major depressive episode. Criteria C and D were not assessed, and E was only assessed for bereavement. The minimum severity requirement is that these symptoms cause help-seeking or subjective impairment (at least one "Yes" to G28-G31). Criterion A for the diagnosis of major depressive episode in DSM- III calls for "dysphoric mood or loss of interest or pleasure in all or almost all usual activities and pastimes." If the respondent said "Yes" to the initial depression question (G2), or if there were at least two weeks of dysphoria combined with some other problems (G26), then the person was said to have "dysphoria," and was considered to have met Criterion A for the diagnosis of major depressive episode (MQPDYSFR=1). The DSM-III definition of Criterion B for major depressive episode contains eight symptoms, at least four (4 <=MQPDGPSW <= 8) of which must be present during a depressive episode in order to qualify for a diagnosis. These eight symptoms are approximated by the following NHANES III questions (Note that the DSM-III Symptoms are given in the order that they are asked in the DIS, rather than the order in the DSM-III Manual): DSM-III Symptom NHANES III Questions 1. Appetite or weight change G05W, G06W, or G07W 2. Insomnia or hypersomnia G08W or G09W 3. Loss or energy, fatigue G10W 4. Agitation or retardation G11W or G12W 5. Loss of interest in sex G13W 6. Feeling worthless or guilty G14W 7. Trouble thinking, concentrating G15W or G16W 8. Thoughts of death or suicide G17W, G18W, G19W, or G20W MQPDGP1W-MQPDGP8W give the number of positive items per group for the eight corresponding groups above. Criterion "E" is only assessed by the absence of uncomplicated bereavement as the cause of depression, i.e., depressed spells were never due to the death of someone close to the respondent or they may have been caused by things other than death (MQPG34 = 2). The variable MQPDEP can take seven values: 1 No diagnosis 2 Major depressive episode without severity 3 Major depressive episode with severity 4 Severe bereavement 5 Non-severe bereavement 88 Blank but applicable Blank MQPDEP = 1. No major depressive episode was diagnosed if the respondent answered sufficient questions so that Criteria A and B could be determined and did not qualify for a diagnosis of major depressive episode or bereavement (as defined below). MQPDEP = 2. Major depressive episode without severity was diagnosed if Criteria A, B and E were met but without severity (all no's for G28-G31). MQPDEP = 3. Major depressive episode with severity was diagnosed if Criteria A, B, and E were met plus severity (at least one "Yes" to G28-G31). MQPDEP = 4. Severe bereavement meets Criteria A and B plus severity (i.e., MQPDEP=3), but depressed spells ONLY due to death of someone close (MQPG34=1). MQPDEP = 5. Non-severe bereavement meets Criteria A and B but not severity (i.e., MQPDEP=2), but depressed spells ONLY due to death of someone close (MQPG34=1). MQPDEP = 88. The major depressive episode variable was coded a "Blank but applicable" value if the respondent did not answer sufficient questions so that Criteria A and B could be determined. The respondent must answer the initial depression question (MQPG02) and at least 11 of the lifetime symptom questions (MQPG05L-MQPG20L) as well as the appropriate worst episode symptom questions (MQPG05W-MQPG20W). MQPDEP = Blank. The major depressive episode variable was coded a "Blank" if the sample person was not eligible to receive the depression questions. MQPDPSX1-MQPDPSX2, MQPDGPSW: Total depressive symptom group counts The two variables MQPDGPSW and MQPDPSX2 report the total number of positive depressive symptom groups in the worst episode (sum of all groups where MQPDGP1W to MQPDGP8W contained at least one positive symptom) and lifetime (sum of all groups where MQPDGP1L to MQPDGP8L contained at least one positive symptom), respectively. The latter also adds dysphoria (MQPDYSFR=1). These variables range from 0-8 and 0-9, respectively. MQPDGPSW is used in determining the diagnosis of major depressive episode and MQPDPSX2 is used in the total symptom count. The variable MQPDPSX1 reports the total number of positive symptoms in the worst episode (sum of MQPDGP1W to MQPDGP8W) plus dysphoria (MQPDYSFR=1) with a range of 0-17. (Note that this variable is a sum of positive symptoms, not positive symptom groups.) MQPFDDP, MQPLDDP: Age of first and last depressive symptoms The two variables MQPFDDP and MQPLDDP code the age of the respondent the first and last time, respectively, he/she experienced depressive symptoms if he/she ever met criteria for any major depressive episode (2 <= MQPDEP <= 5). MQPFDDP uses the age in MQPG32 and MQPLDDP combine the age and time frame information in MQPG35, MQPG36 and MQPG37. MQPMNGP1-MQPNMGP7, MQPEUFOR, MQPMANIA: The diagnostic variable "MQPMANIA" The variable MQPMANIA indicates the diagnosis of manic episode which is based on Criteria A and B of the DSM-III definition of manic episode. Criteria C, D and E were not assessed. The minimum severity requirement is that these symptoms cause help-seeking or subjective impairment (at least one "Yes" in MQPG57-MQPG60). Criterion A for the diagnosis of manic episode in DSM-III calls for "one or more distinct periods with a predominantly elevated, expansive, or irritable mood." If the respondent said "Yes" to the initial mania question (MQPG41L=1) then the respondent was considered euphoric (MQPEUFOR=2). If the respondent said "Yes" (1) to MQPG54 then the respondent was considered irritable (MQPEUFOR=1). The DSM-III definition of Criterion B for manic episode requires a duration of at least one week during which, for most of the time, at least three of the seven symptoms have persisted (four if the mood is only irritable) and have been present to a significant degree. These seven symptoms are approximated by the following NHANES III questions: DSM-III Symptom NHANES III Questions 1. Hyperactivity/hypersexuality G42W or G44W 2. Pressure to keep talking G45W 3. Thoughts racing G46W 4. Inflated self-esteem e.g., special gifts or powers G47W 5. Decreased need for sleep G48W 6. Distractibility G49W 7. Excessive involvement in activities that have a high potential for painful consequences which is not recognized, e.g., buying sprees G43W MQPMNG1W-MQPMNG7W give whether the symptom is present or not for the seven corresponding groups above. The variable MQPMANIA can take five values: 1 No diagnosis 2 Manic episode without severity 3 Manic episode with severity 88 Blank but applicable Blank MQPMANIA = 1. No mania episode was diagnosed if the respondent answered sufficient questions so that Criteria A and B could be determined and did not qualify for a diagnosis of manic episode. MQPMANIA = 2. Manic episode without severity was diagnosed if Criteria A and B were met but without severity (all no's for MQPG57-MQPG60). MQPMANIA = 3. Manic episode with severity was diagnosed if Criteria A and B were met as well as severity (at least one "Yes" for MQPG57-MQPG60). MQPMANIA = 88. The manic episode variable was coded a "Blank but applicable" value if the respondent did not answer sufficient questions so that Criteria A and B could be determined. The respondent must answer the initial mania question (MQPG41), or the irritability question (MQPG54), and at least 6 of the lifetime symptom questions (MQPG41L-MQPG49L) as well as the appropriate worse episode symptom questions (MQPG42W-MQPG49W). MQPMANIA = Blank. The manic episode variable was coded a "Blank" if the sample person was not eligible to receive the mania questions. MQPMNGSW, MQPMNSX1-MQPMNSX2: Total manic symptom group counts The two variables MQPMNGSW and MQPMNSX2 code the total number of positive manic symptom groups in the worst episode (sum of groups MQPMNGP1 to MQPMNGP7 with a "Yes" response) and during lifetime (questions MQPG42L to MQPG49L are grouped into DSM-III groups 1 to 7 and the number of positive groups is counted), respectively. The latter also adds the euphoria or irritability symptom (1 <= MQPEUFOR <= 2). These variables range from 0-7 and 0-8, respectively. MQPMNGSW is used in determining the diagnosis of manic episode and MQPMNSX2 is used in the total symptom count. The variable MQPMNSX1 reports the total number of positive symptoms in the worst episode (sum of MQPMNGP1 to MQPMNGP8) plus euphoria or irritable mood (1 <= MQPEUFOR <= 2) with a range of 0-8. (Note that this variable is a sum of positive symptoms, not positive symptom groups). MQPFDMN, MQPLDMN: Age of first and last manic symptoms The two variables MQPFDMN and MQPLDMN report the age of the respondent the first and last time, respectively, he/she experienced manic symptoms if he/she ever met criteria for any manic episode (2 <= MQPMANIA <= 3). MQPFDMN uses the age in MQPG61 and MQPLDMN combines the age and time frame information in MQPG62, MQPG63 and MQPG64. MQPDEPSE: The diagnostic variable "MQPDEPSE" The variable MQPDEPSE indicates the DSM-III diagnosis of major depression, single episode, and is constructed using MQPDEP and MQPMANIA. The diagnosis of major depression, single episode is not made if the depression is the sole result of severe or non-severe bereavement (MQPDEP= 4 or 5) or if a manic episode is present (MQPMANIA= 2 or 3). There must be only one episode of major depression. The variable MQPDEPSE can take five values: 1 No diagnosis 2 Major depression, single episode without severity 3 Major depression, single episode with severity 88 Blank but applicable Blank MQPDEPSE = 1. No major depressive episode was diagnosed (MQPDEP=1) although there could be severe or non-severe bereavement (MQPDEP=4 or 5) or some form of mania was diagnosed (MQPMANIA=2 or 3). MQPDEPSE = 2. A single episode (MQPG27=1) of major depression without severity was diagnosed (MQPDEP=2) and no manic episodes were present (MQPMANIA=1). MQPDEPSE = 3. A single episode (MQPG27=1) of major depression with severity was diagnosed (MQPDEP=3) and no manic episodes were present (MQPMANIA=1). MQPDEPSE = 88. The major depression, single episode variable was coded "Blank but applicable" if one of the following is true: 1. MQPDEPSE=1 and MQPBIPOL= (Blank or 88) and MQPDEP= (Blank or 88) 2. MQPDEPSE=1 and MQPBIPOL= (Blank or 88) and MQPDEP=3 3. MQPDEPSE=1 and MQPBIPOL=1 and MQPDEP= (Blank or 88) 4. MQPDEPSE=1 and MQPBIPOL=1 and MQPDEP=3 and MQPG27= (Blank, 888, or 999) MQPDEPSE = Blank. The major depression, single episode variable was coded a "Blank" if the sample person was not eligible to receive the depression/mania questions. MQPFDDSE, MQPLDDSE: Age of first and last depressive symptoms associated with major depression, single episode The two variables MQPFDDSE and MQPLDDSE code the age of the respondent the first and last time, respectively, he/she experienced depressive symptoms if he/she ever met criteria for a major depression, single episode which was not due solely to bereavement (2 <= MQPDEPSE <= 3). MQPFDDSE uses the age in MQPFDDP and MQPLDDSE uses the age in MQPLDDP. MQPDEPRT: The diagnostic variable "MQPDEPRT" The variable MQPDEPRT indicates the DSM-III diagnosis of major depression, recurrent, and is constructed using MQPDEP and MQPMANIA. The diagnosis of major depression, recurrent, is not made if the depression is the sole result of severe or non-severe bereavement (MQPDEP=4 or 5) or if a manic episode is present (MQPMANIA= 2 or 3). There must be more than one episode of major depression. The variable MQPDEPRT can take five values: 1 No diagnosis 2 Major depression, recurrent without severity 3 Major depression, recurrent with severity 88 Blank but applicable Blank MQPDEPRT = 1. No major depressive episode was diagnosed (MQPDEP=1) although there could be severe or non-severe bereavement (MQPDEP=4 or 5) or some form of mania was diagnosed (MQPMANIA=2 or 3). MQPDEPRT = 2. Recurrent episodes (2 <= MQPG27 <= (whole life) or don't know how many spells) of major depression without severity were diagnosed (MQPDEP=2) and no manic episodes were present (MQPMANIA=1). MQPDEPRT = 3. Recurrent episodes (2 <= MQPG27 <= (whole life) or don't know how many spells) of major depression with severity were diagnosed (MQPDEP=3) and no manic episodes were present (MQPMANIA=1). MQPDEPRT = 88. The major depression, recurrent variable was coded "Blank but applicable" if one of the following is true: 1. MQPDEPRT=1 and MQPBIPOL= (Blank or 88) and MQPDEP= (Blank or 88) 2. MQPDEPRT=1 and MQPBIPOL= (Blank or 88) and MQPDEP=3 3. MQPDEPRT=1 and MQPBIPOL=1 and MQPDEP= (Blank or 88) 4. MQPDEPRT=1 and MQPBIPOL=1 and MQPDEP=3 and MQPG27= (Blank, 888, or 999) MQPDEPRT = Blank. The major depression, recurrent variable was coded a "Blank" if the sample person was not eligible to receive the depression/mania questions. MQPFDDRT, MQPLDDRT: Age of first and last depressive symptoms associated with major depression, recurrent The two variables MQPFDDRT and MQPLDDRT report the age of the respondent the first and last time, respectively, he/she experienced depressive symptoms if he/she ever met criteria for major depression, recurrent, which was not due solely to bereavement (2 <= MQPDEPRT <= 3). MQPFDDRT uses the age in MQPFDDP and MQPLDDRT uses the age in MQPLDDP. MQPDYSA, MQPDYSD, MQPDYSTH: The diagnostic variable "MQPDYSTH" The variable MQPDYSTH indicates the diagnosis of dysthymic disorder. The diagnosis of dysthymic disorder is based on Criteria A through D of the DSM-III definition of dysthymic disorder. Criteria E and F were not assessed. This disorder differs from major depressive disorder in that during the past two years, the individual has been bothered most or all of the time by symptoms characteristic of the depressive syndrome but that are not of sufficient severity and duration to meet the criteria for a major depressive episode. Criteria A, B, and C of the DSM-III are encompassed in the variable MQPDYSA. This requires two years or more of predominately depressive mood or marked loss of interest or pleasure in all, or almost all, usual activities and pastimes (MQPG03=1 or 104 weeks <= MQPG26 <= whole life). The DSM-III definition of Criterion D for dysthymic disorder contains 13 symptoms, at least three (3 <= MQPDYSD <= 7) of which must be present during the depressive periods in order to qualify for a diagnosis. Seven of these symptoms are covered by the following NHANES III questions. DSM-III Symptom NHANES III Questions 1. Insomnia or hypersomnia G08L or G09L 2. Low energy, chronic tiredness G10L 3. Feeling inadequate/low self- esteem G14L 5. Trouble thinking G15L or G16L 7. Less interest in pleasurable activities G13L 10. Less active or talkative G11L or G12L 13. Recurrent thoughts of death or suicide G17L or G18L or G19L DSM-III symptoms not available in the NHANES III 4. Decreased effectiveness 6. Social withdrawal 8. Irritability 9. Lack of pleasure in rewards 11. Brooding about the past or self-pity 12. Crying spells The variable MQPDYSTH can take five values: 1 No diagnosis 2 Dysthymic disorder with no major depressive episode 3 Dysthymic disorder with major depressive episode 88 Blank but applicable Blank MQPDYSTH = 1. No dysthymic disorder was diagnosed if the respondent answered sufficient questions so that Criteria A through D could be determined and did not qualify for a diagnosis of dysthymic disorder. MQPDYSTH = 2. Dysthymic disorder was diagnosed if the respondent met Criteria A through D but did not have a diagnosis of major depressive episode (MQPDEP not equal to 3). MQPDYSTH = 3. Dysthymic disorder was diagnosed if the respondent met Criteria A through D and had a diagnosis of major depressive episode as well (MQPDEP = 3). MQPDYSTH = 88. The dysthymic disorder variable was coded a "Blank but applicable" value if the respondent did not answer sufficient questions so that Criteria A through D could be determined. The respondent must answer the initial two year depression question MQPG03 or the length of spell question MQPG26 and at least nine of the 12 lifetime symptom questions listed above for Criterion D plus MQPG03. MQPDYSTH = Blank. The dysthymic disorder variable was coded a "Blank" if the sample person was not eligible to receive the depression questions. MQPBIPOL: The diagnostic variable "MQPBIPOL" The variable MQPBIPOL indicates the DSM-III diagnosis of bipolar disorder, and is constructed using MQPDEP and MQPMANIA. The diagnosis of bipolar disorder is made only if there has ever been a manic episode. The variable MQPBIPOL can take eight values: MQPBIPOL = 1. No bipolar disorder was diagnosed if there has never been a diagnosis of manic episode. MQPBIPOL = 2. Bipolar disorder is diagnosed if severity and exclusion criteria are met for both a manic and a major depressive episode (MQPMANIA=3 and MQPDEP=3). MQPBIPOL = 3. Bipolar disorder is diagnosed if severity and exclusion criteria are met for a manic episode (MQPMANIA=3), but a major depressive episode is either absent (MQPDEP=1, 4 or 5) or the diagnosis is missing (MQPDEP=Blank or 88). MQPBIPOL = 4. Bipolar disorder is diagnosed if severity and exclusion criteria are met for a manic episode (MQPMANIA=3), but not for a major depressive episode (MQPDEP=2). MQPBIPOL = 5. Bipolar disorder is diagnosed if no manic episode met both severity and exclusion criteria (MQPMANIA=2) and a major depressive episode is either absent (MQPDEP=1, 4 or 5) or the diagnosis is missing (MQPDEP=Blank or 88). MQPBIPOL = 6. Bipolar disorder is diagnosed if no manic episode met both severity and exclusion criteria (MQPMANIA=2) and the major depressive episodes may or may not meet both severity and exclusion criteria (MQPDEP=2 or 3). MQPBIPOL = 88. The bipolar disorder variable was coded a "Blank but applicable" value if the diagnosis for manic episode is missing (MQPMANIA=Blank or 88). MQPBIPOL = Blank. The bipolar disorder variable was coded a "Blank" if the sample person was not eligible to receive the depression/mania questions. MQPFDBI, MQPLDBI: Age of first and last manic symptoms associated with bipolar disorder The two variables MQPFDBI and MQPLDBI report the age of the respondent the first and last time, respectively, he/she experienced manic symptoms if he/she ever met criteria for any bipolar diagnosis (2 <= MQPBIPOL <= 6). MQPFDBI uses age at first manic symptoms (MQPFDMN) when 2 <= MQPBIPOL <= 6 or age at first depressive symptoms (MQPFDDP) if MQPBIPOL=2, 4 or 6 and 0 <= MQPFDDP <= MQPFDMN. MQPLDBI uses age at last manic symptoms (MQPLDMN) when 2 <= MQPBIPOL <= 6 or age at last depressive symptoms (MQPLDDP) if MQPBIPOL=2, 4 or 6 and MQPLDDP >= 0 and MQPLDMN <= MGPLDDP <= 54. MQPBIPII: The diagnostic variable "MQPBIPII" The variables MQPDEP and MQPMANIA report the DSM- III syndromes of major depressive episode and manic episode, respectively, and are used to construct various DSM-III diagnoses. The variable MQPBIPII is the DSM-III diagnosis of atypical bipolar disorder (bipolar disorder, type II). The diagnosis of atypical bipolar disorder is made only if the respondent: 1. Does not meet criteria for bipolar disorder (MQPBIPOL=1) 2. Does not meet criteria for a manic episode (MQPMANIA=1) 3. Has a major depressive episode (MQPDEP=2 or 3) 4. Has euphoria or irritability (1 <= MQPEUFOR <= 2) 5. Has some symptoms of mania (1 <= MQPMNGSW <= 3) The variable MQPBIPII can take five values: 1 No diagnosis 2 Atypical bipolar disorder without severity 3 Atypical bipolar disorder with severity 88 Blank but applicable Blank MQPBIPII = 1. No atypical bipolar disorder is diagnosed if there has ever been a manic episode (2 <= MQPMANIA <= 3) or bipolar disorder (2 <= MQPBIPOL <= 6) and a major depressive episode is absent or missing (MQPDEP=1, 4, 5, 88, or Blank). MQPBIPII = 2. Atypical bipolar disorder without severity is diagnosed if a major depressive episode without severity is present (MQPDEP=2) and the criteria for a manic episode is not met (MQPMANIA=1) but euphoria or irritability is present (1 <= MQPEUFOR <= 2) and some manic symptoms are present (1 <= MQPMNGSW <= 3). MQPBIPII = 3. Atypical bipolar disorder with severity is diagnosed if a major depressive episode with severity is present (MQPDEP=3) and the criteria for a manic episode is not met (MQPMANIA=1) but euphoria or irritability is present (1 <= MQPEUFOR <= 2) and some manic symptoms are present (1 <= MQPMNGSW <= 3). MQPBIPII = 88. The atypical bipolar disorder variable was coded "Blank but applicable" if one of the following is true: MQPBIPII=1 and MQPDEP= (Blank or 88) 2. MQPBIPII=1 and MQPMANIA= (Blank or 88) and MQPDEP=3 MQPBIPII = Blank. The atypical bipolar disorder variable was coded a "Blank" if the sample person was not eligible to receive the depression/mania questions. MQPFDBII, MQPLDBII: Age of first and last manic symptoms associated with atypical bipolar disorder The two variables MQPFDBII and MQPLDBII report the age of the respondent the first and last time, respectively, he/she experienced depressive symptoms if he/she ever met criteria for any atypical bipolar disorder diagnosis (2 <= MQPBIPII<= 3). MQPFDBII uses age at first depressive symptoms (MQPFDDP) and MQPLDBII uses age at last depressive symptoms (MQPLDDP). MEC ADULT QUESTIONNAIRE (Except DIS) The MEC Adult Questionnaire was administered to all examinees aged 17 years and older in the mobile examination center (MEC). Conducted by a trained interviewer in a private room to ensure confidentiality, the automated questionnaire included sections on drug, alcohol, and tobacco use, sexual experience, women's reproductive history, and mental health. Because this questionnaire was administered in the examination center, the MEC examination sample weight (WTPFEX6) should be used for data analysis. For more information on the use of sample weights in NHANES III data analysis, refer to the NHANES III Analytic and Reporting Guidelines (U.S. DHHS, 1996b). Several portions of the MEC Adult Questionnaire were asked of examinees within specific age groups, and others were specific to one gender. For example, the cognitive-function section was administered to examinees 60 years and older, and the birth control-use section was administered only to women. Age and sex check items that were part of the questionnaire have been retained in the documentation and can be used to determine these subsets. One portion of the questionnaire (Section G), the Diagnostic Interview Schedule, was edited and documented separately (see Diagnostic Interview Schedule). A modified MEC Adult Questionnaire was administered to adults 20 years and older during the interview portion of the Home Examination. It included sections on tobacco use, cognitive function, selected medical conditions, reproductive health, and medicine, vitamin, and mineral usage. Questions from the two interviews can be combined for analysis; however, the analyst should be aware of slight differences between the questionnaires. For example, the reproductive health section of the interview administered in the Home Examination was shorter, and skip patterns were not identical to those in the MEC Adult Questionnaire. For analyses of combined data from the MEC Adult and the Home Examination interviews, MEC+home examination weights (WTPFHX6) should be used (see Home Examination, Interview). Data processing and editing were performed for the consistency of responses within the sections of the questionnaire. Notes have been provided both for standardized and recoded variables and for variables requiring additional explanation. The notes reference the questions, by section and number, from the questionnaires which can be found in the Plan and Operation of the National Health and Nutrition Examination Survey, 1988-1994 (NCHS, 1994; U.S. DHHS, 1996b).

MAPE3S: Number of days drank alcohol in past year This variable was created from the two-part (quantity and unit) question E3 using the conversion factors 52 weeks/year and 12 months/year. MAPE5S: Number of days drank nine or more drinks of alcohol in past year This variable was created from the two-part (quantity and unit) question E5 using the conversion factors 52 weeks/year and 12 months/year. MAPE6S: Number of days drank five or more drinks of alcohol in past year This variable was created from the two-part (quantity and unit) question E6 using the conversion factors 52 weeks/year and 12 months/year. MAPF7R: Age at time of first live birth Question F7 (age at time of first live birth) was only asked of women who had more than one live birth. To prevent redundant questions, women who had one live birth were only asked question F8, "Age at the time of the last live birth." This variable, MAPF7R, was created to include responses for women who had only one live birth and women who had multiple births. For women who had only one live birth, their responses to question F8 were coded into MAPF7R. For women who had multiple births, their responses to question F7 were coded into MAPF7R. MAPF12R: Pregnancy status recode This variable combines responses from self-reported pregnancy status (F12) with the results of urine pregnancy test conducted in the mobile examination center on women 20-49 years of age. If either the self-report or the test result was positive, then MAPF12R was coded yes. Otherwise, if either the self-report or test result was negative, then MAPF12R was coded no. If the self-report was don't know and the test result was either inconclusive or blank but applicable, then MAPF12R was coded don't know. If the self-report was blank but applicable and the test result was inconclusive, then MAPF12R was also coded don't know. Finally, if both responses were blank but applicable, then MAPF12R was coded blank but applicable. MAPF18S: Number of months received WIC benefits This variable was created from the two-part question (quantity and unit) F18 using the conversion factor 12 months/year. MAPF23: Age at last period There were no comments or related responses that could be used to clarify the responses for reported ages of last period that appeared to be extreme. Analysts should review responses when using this variable. MAPF32S: Months since stopped taking birth control pills This variable was created from the two-part question (quantity and unit) F32 using the conversion factor 12/months per year. MAPF33S: Total number of months took birth control pills This variable was derived from the two-part question (quantity and unit) F33 using the conversion factors 12 months/year. Analysts should note that the reported length of time on birth control pills may have exceeded the length of time that these products were available in the U.S. MAPF34R: Birth control pill codes This variable was created to include a listing of all birth control pills that were specified in question F34. It includes both birth control pills that had original codes from the chart that respondents were shown as well as those not included on the chart but specified by the respondent. See the Appendix at the end of this section for code listing. MAPF34CS: Number of months since NORPLANT was implanted This variable was derived from the two-part question (quantity and unit) F34C using the conversion factor 12 months/year. Analysts should be aware that the reported length of time NORPLANT was used may have exceeded the length of time that this product was available in the U.S. MAPF39S: Number of months since stopped taking estrogen pills This variable was created from the two-part question (quantity and unit) F39 using the conversion factor 12 months/year. MAPF40: Total years on estrogen pills Analysts should be aware that the reported length of time for estrogen pill use may have exceeded the length of time that these products were available in the U.S. MAPF43S: Number of months since stopped using estrogen cream, suppository, or injection This variable was created from the two-part question (quantity and unit) F43 using the conversion factor 12 months/year. MAPF44: Total years used estrogen cream, suppository, or injection Reported length of time for use of these estrogen products may have exceeded the length of time that they were available in the U.S. MAPF47S: Number of months since stopped using hormone patches This variable was created from the two-part question (quantity and unit) F47 using the conversion factor 12 months/year. MAPF48: Total years used female hormone patches Reported length of time for use of hormone patches may have exceeded the length of time that these products were available in the U.S. MAPF50: Age at first sexual intercourse The question did not ask about first consensual sexual experience. Therefore, responses of first intercourse at very young ages were retained after reviewing comments made during the interview (e.g., reports of rape or incest). MAPF51: Number of sexual partners The value "990" represents reports of more than 990 sexual partners as well as responses such as "too many to count." MAPF53: Sex of sexual partners This question was about sexual experience; it was not designed to determine sexual preference. MAPF54R: Number of partners that were female If the response to this question was that all partners were female, then this variable was recoded as the number of female partners reported in F51. MAPF57: Ever had genital herpes In Phase 1, this question was asked, "Have you ever had genital herpes?" In Phase 2, the question was changed to, "Has a doctor ever told you that you had genital herpes?"

Using dual energy x-ray absorptiometry (DXA), areal bone density (bone mass per unit of area scanned) was measured in five areas of the proximal femur. These were the femoral neck, trochanter, intertrochanter, Ward's Triangle, and total region. Before the exam, screening questions were asked to determine medical safety exclusions. Those excluded from testing were examinees: who were females below age 60 for whom pregnancy test results were positive or uncertain or for whom there was a possibility of pregnancy; for whom both hips had been fractured or broken previously; or who had hip pins or artificial hips. Because these tests were administered in the mobile examination center, the MEC examination sample weight (WTPFEX6) should be used for data analysis. For more information on the use of sample weights in NHANES III data analysis, refer to the NHANES III Analytic and Reporting Guidelines (U.S. DHHS, 1996b). A rigorous quality control program was used throughout the survey to ensure data quality. Quality control (QC) of each individual DXA instrument was monitored by scanning anthropomorphic phantoms on a frequent basis (daily for spine phantom, weekly for hip phantom). Comparability of the three DXA instruments was assessed by circulating an additional spine phantom between mobile examination centers; this "circulating spine phantom" was scanned once per stand. Every anthropomorphic phantom scan was reviewed individually at the Mayo Clinic, and results were plotted to compare with previous QC scan results. All respondent scans also were reviewed individually at the Mayo Clinic before being added to the database. For a detailed description of the QC program and the results for Phase 1 of NHANES III, see the reference by Wahner (1994). QC results for Phase 2 were similar to those for Phase 1. Additional details about the bone density procedure may be found in the references by Looker (1995) and Hologic (1987). Data processing and editing were performed to ensure internal data consistency.

whether or not the examinee was ineligible to receive the bone densitometry procedure because of known or possible pregnancy or because both right and left hips had been fractured, pinned, or replaced with artificial hip joints in the past. BDPSCAN: Scan technically acceptable after review at the Mayo Clinic See 1994 reference by Wahner for rejection criteria. BDPSIDE: Hip side that was scanned The left hip was chosen as the default side for the bone density scan because it was easier to scan this side given the position of the DXA scanner in the bone density room. If the left hip had been pinned or fractured previously or was artificial, the right hip was scanned. BDPWTARE, BDPWTBMC, BDPWTBMD: Bone mineral area, content, and density of Ward's Triangle region Phases 1 and 2 data for Ward's Triangle are not directly comparable due to a change in the DXA software used to process the data. In Phase 1, the location of Ward's Triangle was variable. The computer algorithm actually searched a specific portion of the femur neck and intertrochanter (2.7 cm x 3.5 cm) for the lowest point of bone mass and then centered a fixed area box (10.5 mm x 10.5 mm)around this point. In Phase 2, however, the location was fixed. The Ward's Triangle position was fixed at a mid-cervical location rather than being the point of lowest bone mineral density. Thus, users should be careful in interpreting observed differences in Ward's Triangle data between Phases 1 and 2. In addition, combining Ward's Triangle data from Phases 1 and 2 may not be appropriate. BDPWTBMC: Bone mineral content of Ward's Triangle See note for BDPWTARE. BDPWTBMD: Bone mineral density of Ward's Triangle See note for BDPWTARE. HOME EXAMINATION, INTERVIEW The Home Examination interview was administered at the homes of examinees aged 2-11 months and those aged 20 years and older who were unable to travel to the mobile examination center (MEC). The interview included sections similar to those found in other MEC questionnaires: infant food frequency, cognitive function, selected conditions/medicine, vitamin and mineral usage, tobacco use, and reproductive health. Data from examinations conducted in the home (body measurements, physical function, spirometry, and venipuncture) have been included with the corresponding examination and laboratory data; therefore, they have not been included here. Items from the MEC Adult Questionnaire and the Home Examination interview can be combined for analysis; however, there may be slight differences in the questions the way in which they are administered. For example, the reproductive health section in the interview during the Home Examination was shorter, and the skip patterns were not the same. For analysis of the Home Examination interview data alone or for combined MEC and Home Examination questionnaire data, the MEC+home Examination weights (WTPFHX6) should be used. Separate sample weights were not created for the Home Examination. For more information on the use of sample weights in NHANES III data analysis, refer to the NHANES III Analytic and Reporting Guidelines (U.S. DHHS, 1996b). The interview during the Home Examination was brief in comparison to those conducted in the MEC. Like the MEC questionnaires, certain sections were asked only of specific age and gender groups. For instance, reproductive health questions were asked only of females aged 20 years and older. Cognitive function questions were asked of examinees age 60 years and older. Tobacco use was asked of examinees aged 20-60 years. The infant food frequency was asked of a parent or other adult in the household member for each child aged 2-11 months. Data processing and editing were performed for the consistency of responses within the sections of the questionnaire. Notes have been provided for variables that were standardized or recoded or those that require additional comments.

HXPH22: Total years on estrogen pills Reported length of time for use of estrogen pills may have exceeded the length of time that these products were available in the U.S. GALLBLADDER ULTRASONOGRAPHY Gallbladder examinations were conducted on all examinees aged 20 to 74 years by a certified ultrasound technician in the mobile examination center (MEC). The protocol for this component did not detail any medical, safety or other exclusions. When analyzing these data, the MEC examination sample weight should be used (WTPFEX6). For more information on the use of sample weights in NHANES III data analysis, refer to the NHANES III Analytic and Reporting Guidelines (U.S. DHHS, 1996b). Gallbladder examinations were conducted to estimate the prevalence of gallstone disease in the United States. Testing was done on examinees in both supine and left decubitus positions. The main element of the exam was real-time ultrasonography, a non-invasive technique for detecting gallstones. Although sample persons were asked to fast for at least six hours before the examination, non-fasting persons were not excluded from the examination. The rate of acceptable exams did not differ by fasting status. Details of the data collection procedures and data collection forms for the Gallbladder Ultrasonography component are included in the Gallbladder Ultrasonography Procedures Manual (U.S. DHHS, 1996b) and the Plan and Operation of the Third National Health and Nutrition Examination Survey, 1988-94 (U.S. DHHS, 1996b). All certified ultrasound technicians received training in the physics of ultrasound, calibration of equipment, and technique of administering the abdominal ultrasound examination. This training was conducted at the time of hire and at least annually thereafter by a radiologist and a physicist who were experts in ultrasonography. All examinations were recorded on videotapes and mailed to consulting radiologists who specialized in abdominal ultrasonography. No written comments or technician findings were disclosed to the radiologists to ensure an independent review of cases except for the "rapid review" cases (in which immediate evaluations were needed due to abnormal findings potentially requiring medical attention). A diagnosis of gallstones was made using the common criteria of echoes within the gallbladder with shadowing on two views. Diagnoses first were obtained by the ultrasound technician in the MEC and later were confirmed by a radiologist. If a right upper quadrant or epigastric scar was observed and the gallbladder was not seen, it was concluded that a cholecystectomy had been performed previously. Data for other abnormal pathologies observed in the surrounding areas, such as the liver or the right kidney, also were collected and recorded. Persons in wheelchairs received the ultrasound examination while sitting. The radiologists' diagnoses in GUPR1DX1 and GUPR1DX2 were compared with the technicians' diagnoses in GUPTDX1R and GUPTDX2R. If they agreed with each other, then these were used as the final diagnoses (GUPFDX1R and GUPFDX2R). If the radiologist and the technician disagreed and the radiologist was not confident of the finding because of the poor quality of the video, then the technician's diagnosis was used as the final diagnosis. Also if the radiologist's diagnosis was missing, then the technician's diagnosis was used as the final diagnosis. However, if the radiologist and the technician disagreed and the radiologist had reasonable confidence in his/her findings, then the video taped scan was given to a senior radiologist for adjudication, and that senior radiologist's diagnosis was used as the final diagnosis. The level of agreement between the technician's diagnosis and the radiologist's diagnosis was measured by the Kappa statistic and was found to be excellent (Fleiss, 1981). Analysts should use both final primary and secondary diagnosis variables in analyses. If gallstones were present (codes 3-5), it was indicated in the final, primary diagnosis (GUPFDX1R). Data processing and editing were performed to ensure internal data consistency. Notes have been provided for variables requiring additional explanation. Supplemental information was collected during the household interview. Section J of the Household Adult Questionnaire included questions on self-reported history of abdominal pain, previous diagnosis of gallstones, gallbladder surgery, and medical treatment to dissolve or remove gallstones. A question on newer methods to dissolve gallstones or remove the gallbladder was added in Phase 2 of the survey. This information can be found in the Household Adult Data File.

The final primary and secondary diagnoses were a result of this adjudication. Most examined persons had only a single diagnosis, and the code for that diagnosis was placed in GUPFDX1R. For those persons with two diagnoses, the lowest numbered code was placed in GUPFDX1R, and the other code was placed in GUPFDX2R. However, analysts should check both variables for specific codes of interest. GUPGBPSZ: Size of the largest polyp GUPGBPSZ indicates the size of the largest polyp if a polyp was found during the technician's examination or after the radiologist's review (code 13 in either GUPFDX1R or GUPFDX2R). GUPLCSTR, GUPLCSZE: Flag for liver cyst and the size of the largest cyst During the examination, the technician scanned the area surrounding the gallbladder for other abnormal pathologies. Liver abnormality is identified in the variable GUPQ38R. GUPLCSTR indicates the presence of one or more cysts in the liver. GUPLCSZE indicates the size of the largest cyst. GUPLHMGR, GUPCHSZE: Flag for cavernous hemangioma of liver and size of the largest lesion During the examination, the technician scanned the area surrounding the gallbladder for other abnormal pathologies. Liver abnormality is identified in the variable GUPQ38R. The presence of one or more hemangiomas of the liver is recorded in the variable GUPLHMGR. The size of the largest lesion is recorded in the variable GUPCHSZE. GUPQ18: Thickness of gallbladder wall The gallbladder for a person in a non-fasting state may be contracted and appear to have a thickened wall. In such cases, the gallbladder wall thickness may be greater than 3 mm and, according to the computerized recording of results, would have been recorded as code 14, "Abnormal GB -- Diffuse W.T., With NO Calcification" although the gallbladder appeared to be normal to technicians and radiologists. For those persons in a non-fasting status with a contracted gallbladder, the final adjudicated diagnosis was edited and appropriately coded to indicate a normal gallbladder. GUPQ24R: Measurement of largest echo -- clump (mm) This variable provides measurement of the largest gallstone (codes 3 and 4 in GUPFDX1R or GUPFDX2R). GUPQ37R: Other non-gallbladder findings -- renal This variable is a recode of the response to question Q37. GUPQ38R: Other non-gallbladder findings -- hepatic or liver This variable is a recode of the response to question Q38. GUPQ8A1-GUPQ8A6: Flag for abdominal scar and its location To identify the location of a scar in GUPQ8A1-GUPQ8A6, refer to the upper body illustration (p. 394) of the Plan and Operation of the Third National Health and Nutrition Examination Survey, 1988-94 (NCHS, 1994; U.S. DHHS, 1996b). GUPR1CNF, GUPR1QLT: Radiologist's confidence in diagnoses and assessment of quality of the videotape (first reading) Three levels were used on the quality control form to record the radiologist's confidence in the diagnoses and assessment of the videotape quality. If for either variable, level 3 was marked, diagnoses from the corresponding readings were not used in computing the final, adjudicated primary and secondary diagnoses. GUPR1DX1, GUPR1DX2: Radiologists' first reading All videotaped scans were mailed to a radiologist for evaluation, which was recorded on a quality control form. After reviewing the scanned cases, the radiologist marked a maximum of two diagnoses on the quality control form and then evaluated the quality of the tapes, confidence in the diagnosis, and sometimes provided an optional, written comment explaining the diagnosis. Most examined persons had only a single diagnosis, and their code was placed in GUPR1DX1. For those persons with two diagnoses, the lowest numbered code was placed in GUPR1DX1, and the other code was placed in GUPPR1DX2. However, analysts should check both variables for specific codes of interest. GUPR1ID, GUPR2ID: Radiologists' identification numbers These are identification numbers for the radiologists reviewing the videotapes. A total of four radiologists reviewed the videotapes under professional services contracts. After the first reading, all cases with significant disagreements between the technician's diagnosis and the radiologist's diagnosis were reevaluated by the senior radiologist (radiologist number 4). GUPRCSTR, GUPRCSZE: Flag for renal cyst and the size of the largest cyst During the examination, the technician scanned the area surrounding the gallbladder for other abnormal pathologies. Right kidney abnormality is identified in the variable GUPQ37R. The presence of one or more cysts in the kidney is identified in the variable GUPRCSTR. GUPRCSZE indicates the size of the largest cyst. GUPTDX1R, GUPTDX2R: Technician's primary and secondary diagnoses Most examined persons had only a single diagnosis, and the code was placed in GUPTDX1R. For those persons with two diagnoses, the lowest numbered code was placed in GUPTDX1R, and the other code was placed in GUPTDX2R. However, analysts should check both variables for specific codes of interest. CENTRAL NERVOUS SYSTEM FUNCTION EVALUATION Computerized neurobehavioral testing was administered to a random half-sample of examinees aged 20-59 years by a trained examiner in a soundproof room in the mobile examination center (MEC). A screening questionnaire was administered to assess factors that might have affected test performance. There were no medical or safety exclusions for this component. Because this examination was administered on a selected subsample in the examination center, the central nervous system (CNS) sample weight (WTPFCNS6) should be used for data analysis. For more information on the use of sample weights in NHANES III data analysis, refer to the NHANES III Analytic and Reporting Guidelines (U.S. DHHS, 1996b). Three computerized tests were used to evaluate central nervous system function. They were: (1) a simple reaction time test (SRTT), a basic measure of motor response speed to a visual stimulus; (2) a symbol-digit substitution test (SDST), a test of coding ability; and (3) a serial-digit learning test (SDLT), a short-term memory test. These tests are components of the Neurobehavioral Evaluation System 2 (NES2) developed by Baker and Letz (1985; Letz, 1990). NES2 is a system of computerized tests designed to assess neurobehavioral function in epidemiological studies of populations with occupational or environmental exposure to chemicals. The tests were administered on a Compaq 286 DeskPro(TM) personal computer (12.5 MHz, 80286 CPU chip) configured with 640K RAM, one 1.2MB floppy disk drive, one parallel port, two serial ports, a standard game joystick controller board, and an Ethernet interface board. The system used the standard, detachable keyboard with a custom-made wooden keyboard overlay that left only the top row of digit keys exposed to prevent inadvertent contact with keys not needed in the testing; it also used a standard, monochrome (green) Compaq monitor. In September 1991, between the conclusion of Phase 1 and the initiation of Phase 2 data collection, the monitors were replaced with comparable, new amber monitors due to a deterioration in display performance. A push-button, computer-game joystick (NES2 Joystick by Neurobehavioral Systems, Inc., Winchester, MA) was used to record the SRTT responses. The tests were administered by health technicians, MEC interviewers, and translators who were trained to perform the testing. Before examinations began, special training sessions were held at NCHS or at the offices of the contractor responsible for survey operations. Training sessions also occurred at MEC sites during the survey, and retraining was done approximately twice per year. The test was conducted in English or Spanish, and examinees who could not speak English or Spanish were not tested. English or Spanish language instructions appeared on the computer screen for each test, and the examiner also gave the instructions verbally. Translators were trained to administer the testing independently or with a health technician. The training was conducted in the MEC by a Spanish-speaking health technician, Spanish-speaking NCHS staff member, or Spanish-speaking MEC interviewer trained to administer the CNS test. Training for translators included reviewing the manual with the trainer, performing the tests as an examinee, and administering the examination in Spanish. Physical comfort may have affected examinees' test results. The air conditioning in the soundproof room used for testing sometimes failed to maintain an optimally comfortable room temperature. Because of this, room temperature (CNPTEMP) was recorded for use as a covariate; however, this practice did not begin until the second year of the survey. The location of the thermometer within the room and the time that temperature was recorded were not consistent throughout the survey. For instance, some examiners entered the temperature at the beginning of the testing session, and others recorded it at the end of the session. This source of error is likely to be small. Initially, some trials of the SRTT were performed with both the non-preferred hand and the preferred hand. Early in the survey, the procedure was changed to perform all trials only with the preferred hand. As a result, analysts may want to exclude SRTT data from those examinees who used both hands for the test. The affected data have a value of "2 Non-preferred hand used on trials 31-50" for the variable CNPNBPH (LOG: Number of trials with preferred hand). During Phase 2 of the survey, reading glasses were available for examinees who forgot to bring their own reading glasses to the MEC. Examinees could select from four pairs of glasses of different diopters or magnifying powers (+1.0 diopter, +1.5 diopters, +2.0 diopters, and +2.5 diopters). Although all examiners were well-trained in standardized procedures for these tests, performance on neurobehavioral tests may have been subject to an examiner effect. This would have been particularly likely when the examiner encouraged the examinee during the exam, as was the case in NHANES III. Therefore, analysts should consider using the examiner number (CNPTECH) as a covariate in analyses of data from these tests. For details of the examination protocol, see the Neurobehavioral Testing Procedures Manual (U.S. DHHS, 1996b). Data processing and editing were performed to ensure internal data consistency. Notes have been provided for variables requiring additional explanation.

CNP2LAT1-CNP2LAT9, CNP3LAT1-CNP3LAT9, CNP4LAT1-CNP4LAT9: Latencies for trials 1-4 A total of five trials were conducted in the Symbol Digit Substitution Test (SDST), a practice trial (not included in these data) and four actual trials (trials 1-4). The practice trial was primarily for training the examinee in the test procedure. It did not accept incorrect responses, and data from the practice trial are not included in this file. If the examinee entered an incorrect digit, a short beep sounded, and no digit was entered on the screen; to proceed, a correct digit had to be entered. If the examinee made more than four errors during the practice trial, the trial was repeated. If the examinee made more than four errors on the second attempt of the practice trial, the test was discontinued, and the next test was initiated automatically. Symbols and digits were paired differently on each trial. Although incorrect responses were allowed on the four actual trials, more than four errors resulted in a message emphasizing the need to avoid errors. These variables represent the latency to enter each of the nine digits of each trial. Incorrect responses were reported as negative values. CNP1SCOR-CNP8SCOR: Serial Digit Learning Test (SDLT) score Note that to allow comparison with NES2 results from other settings the scoring convention for this variable differs from that usually applied to the NHANES III data, where 0 indicates none or never. Examinees received a score of 0 if all eight digits were entered correctly, 1 if six or seven digits were entered correctly, and 2 if fewer than six digits were entered correctly. CNP1TOTL, CNP2TOTL, CNP3TOTL, CNP4TOTL: Total latency, trials 1-4 CNP1TOTL represents the time elapsed on trial 1 from the time the first item was answered to the time the ninth item was answered. Therefore, it does not include the latency to respond to the first symbol. CNP2LAT1-CNP2LAT9: Latencies for trial 2 See note for CNP1LAT1-CNP1LAT9.

CNPCBEST: Mean of two lowest error-corrected latencies This single summary measure for the SDST is the mean of the error-corrected latencies (CNPCLAT1-CNPCLAT4) on the two best (lowest latency) of the four trials. The units for this summary measure are "sec/correct digit." CNPCLAT1, CNPCLAT2, CNPCLAT3, CNPCLAT4: Error-corrected latency for trials 1-4 The error-corrected latency was calculated for each of the four actual trials. It is the mean number of seconds per correct digit for each trial, excluding the first item in the trial. If the number of correct responses for latencies 2 through 9 was 0, CNPCLAT1 was set to missing (blank). Otherwise, CNPCLAT1=CNP1TOTL/CNPCORR1. CNPCLAT2: Error-corrected latency for trial 2 See note for CNPCLAT1. CNPCLAT3: Error-corrected latency for trial 3 See note for CNPCLAT1. CNPCLAT4: Error-corrected latency for trial 4 See note for CNPCLAT1. CNPMENRT: Mean reaction time To calculate the mean reaction time, values from the first ten trials (CNPRT01-CNPRT10) were excluded as well as values from other trials that were greater than or equal to 750 msec or less than or equal to 50 msec. This mean may not be valid if the number of trials included in the average was less than 20. CNPSDRT: Standard deviation of the reaction time To calculate the standard deviation of the reaction time, values from the first ten trials (CNPRT01-CNPRT10) were excluded as well as values from other trials that were greater than or equal to 750 msec or less than or equal to 50 msec. This statistic may not be valid if the number of trials included in the calculation was less than 20. FUNDUS PHOTOGRAPHY A photograph of the ocular fundus of one eye was taken on examinees aged 40 years and over by a trained examiner in the mobile examination center (MEC). The protocol for this component did not detail any medical, safety or other exclusions. However, if the designated eye was unavailable due to an extremely small pupil, severe corneal or lens opacity, complete retinal detachment, or other reason, the other eye was photographed. If both eyes were unavailable, no photograph was taken. Because the component was administered in the examination center, MEC examination weights (WTPFEX6) should be used for data analysis. For more information on the use of sample weights in the analysis of NHANES III data, refer to the NHANES III Analytic and Reporting Guidelines (U.S. DHHS, 1996b). Photographs of the ocular fundus were taken to determine the presence of diabetic retinopathy, age-related maculopathy, and other retinal diseases that are the leading causes of vision loss in the United States. A non-stereoscopic, color, 45-degree photograph, centered between the optic nerve and the macula, was taken of one randomly selected eye. The camera used was a Canon CR4-45NM "non-mydriatic" fundus camera, which incorporated the use of an infrared video camera to allow photographs to be taken in a darkened examination room without the use of dilating drops. In a darkened room, the sphincter muscle of the iris normally relaxes, allowing for dilation of the pupil, usually to 6-10 mm in diameter. The technician observed the eye's natural dilation on a special video monitor and took the color photograph with a single flash of white light. If the examinee wore a contact lens, the photograph was taken directly through the contact lens. The entire procedure usually took less than six minutes. Detailed information on the examination procedure is in the Fundus Photography chapter of the Health Technician's Manual (U.S. DHHS, 1996b). The exposed film was mailed to the University of Wisconsin-Madison, Department of Ophthalmology, where it was processed by a local laboratory into transparencies that were evaluated for photographic quality. The ocular fundus images on the final transparencies were reviewed by photograph graders to assess the presence of diabetic retinopathy, age-related maculopathy, and other retinal diseases. The grading system used for classifying diabetic retinopathy was based on a modification of the Airlie House Classification Scheme (Diabetic Retinopathy Study Group, 1981; Klein, 1984; Klein, 1986; The Early Treatment Diabetic Retinopathy Study Group, 1991). The Modified Airlie House Classification of Diabetic Retinopathy slide standards consist of 27 stereo pairs of color fundus photographs of diabetic retinopathy and one slide depicting poor photographic quality. The standard slides show diabetic proliferative disease and are used for grading the severity of diabetic retinopathy. The set is available with a detailed chapter outlining its use and a sample grading form. Additional information is available from The Fundus Photograph Reading Center, c/o Michael Neider, WARF Building Room 450, 610 Walnut Street, Madison, WI 53705. The fundus photography consultant provided extensive training to technicians at their time of hire, and each technician's performance was monitored in the field on a periodic basis. Two sources of nonsampling or measurement error were monitored throughout the survey, the picture taking procedure and the image grading procedure. To ensure that adequate photographs were taken, the technicians' performance was monitored by a review of photographs at the University of Wisconsin and by review and retraining field visits. To evaluate the grading procedure, 1500 transparencies were chosen at random for use in assessing inter- and intra-grader reliability. The Kappa statistic was chosen to assess agreement (Fleiss, 1981). The measures of agreement were generally good to excellent and improved across time. Data processing and editing were performed to ensure internal data consistency. Notes have been provided for variables requiring additional explanation.

When the fundus was absent (FPP1020=00), the grader was instructed to stop. All ensuing fields, FPP1030 through FPP1270, were then left blank by the grader. During data processing, the blank fields were recoded "88 Blank but applicable." FPP1060: Gradability status Not all photographs were gradable. The principal reasons were related to the camera (e.g., malfunction, poor focus, dirty lens) and to the examinee (e.g., cataracts, eye movement, corneal change, poor pupil dilation, lens implants). The grader was instructed to stop when the entire field was ungradable (FPP1060=06), at which point the remaining fields were left blank. During data processing, the blank fields were recoded "88 Blank but applicable." FPP1070: Diabetic retinopathy level This variable represents the current state of severity of retinopathy in the eye. As such, it differs from the summary diabetic retinopathy score (FPPSURET) which represents the combination of current and past retinopathy status. FPP1230-FPP1266: Drusen details Drusen vary in appearance, merging at one end of the spectrum with the normal fundus background and at the other end with diffuse degeneration of the retinal pigment epithelium. Typical small drusen usually appear as individual, round, flat spots in the plane of the retinal pigment epithelium. They may be pale yellowish-white, contrasting sharply with the surrounding retinal pigment epithelium, or only slightly more pale than the retinal pigment epithelium and easily overlooked, even with careful examination of well-focused photographs. Larger drusen typically are yellow-white in color and often have visible thickness. Some have sharp margins and a solid, nodular appearance, whereas others have indistinct margins and a softer, more liquid appearance. Drusen may be distributed as individual spots or may appear to merge with adjacent drusen. In NHANES III, two characteristics of drusen type (hard or soft) and area were graded in a semi-quantitative fashion within and outside the grid. Small punctate drusen (usually less than 95 microns in diameter) were classified as hard drusen; larger drusen were classified as soft. No attempt was made to further characterize soft drusen by appearance as soft distinct or indistinct. Drusen area was estimated within a central circle of the grid, within the grid, and outside the grid. The area covered by drusen was estimated by mentally moving together all hard or soft drusen as if they were confluent and comparing this area with those of standard circles. The estimate of drusen area was classified into one of four categories: smaller than a circle with a diameter of 95 microns (comparable to the 63-micron diameter circle used in a 30-degree field), smaller than a circle with a diameter of 375 microns (250-micron diameter in a 30-degree field), smaller than a circle with a diameter of 960 microns (640-micron diameter in a 30-degree field), or equal to or larger than a circle with a diameter of 960 microns. FPPPHOTO: Photographic status Fundus photographs were not taken on all examinees who came to the mobile examination center. The principal reasons were refusal to cooperate, equipment failure, physical inability, and insufficient time. FPPSUDRU: Summary drusen score The summary drusen score was derived from a combination of values from several variables. Definite drusen present: FPP1230, hard drusen, and/or FPP1240, soft drusen, were coded "02 Yes." Questionable drusen present: Definite drusen were not present, and FPP1230, hard drusen, and/or FPP1240, soft drusen, were/was coded "01 Questionable." No drusen present: Neither definite nor questionable drusen was present, and FPP1230, hard drusen, and/or FPP1240, soft drusen, were/was coded "00 None." Cannot grade drusen: FPP1230, hard drusen, and FPP1240, soft drusen, were both coded "08 Can't grade." Blank but applicable: FPP1060, gradability, was coded "06 Entire field ungradable," or FPP1020, fundus, was coded "00 Absent" or "88 Blank but applicable." FPPSUMAC: Summary age-related maculopathy score The summary age-related maculopathy score was derived from a combination of values from several variables. A detailed description of lesions as defined by the Wisconsin Age-Related Maculopathy Grading System is available (Klein, 1991; NTIS, 1991). Late age-related maculopathy: At least one of the following variables was coded "02 Yes." FPP1174, geographic atrophy FPP1176, sub-retinal hemorrhage FPP1178, sub-retinal fibrous scar FPP1180, sensory serous (sub-retinal) detachment Early age-related maculopathy: At least one of the following three sets of conditions was met. FPP1172, degeneration of retinal pigment epithelium (RPE), was coded "02 Yes," and (FPP1230, hard drusen, and/or FPP1240, soft drusen, were/was coded "02 Yes"). FPP1182, hyperpigmentation, was coded "02 Yes," and (FPP1230, hard drusen, and/or FPP1240, soft drusen, were/was coded "02 Yes"). FPP1240, soft drusen, was coded "02 Yes," and FPP1250, grid area, was coded 02-04 (equal to or greater than a circle 95 microns in diameter). No age-related maculopathy: Early and late age-related maculopathy definitions were not met, and FPP1240, soft drusen, was coded 00-02 (gradable). "Cannot grade" age-related maculopathy: Early and late age-related maculopathy definitions were not met, and FPP1240, soft drusen, was coded "08 Can't grade." Blank but applicable: FPP1060, gradability, was coded "06 Entire field ungradable," or FPP1020, fundus, was coded "00 Absent" or "88 Blank but applicable." FPPSURET: Summary diabetic retinopathy score The summary diabetic retinopathy score was derived from a combination of values from several variables. That is, it combines the diabetic retinopathy level variable (FPP1070) and history of treatment for proliferative diabetic retinopathy (using the photocoagulation treatment outside the arcades variable (FPP1214) as a marker). A detailed description of lesions as defined by The Early Treatment Diabetic Retinopathy Study (ETDRS) is available in the ETDRS report #10 (The Early Treatment Diabetic Retinopathy Study, 1991). The NHANES III fundus photo grading protocol (NTIS, 1995) describes methods of assigning diabetic levels. Proliferative diabetic retinopathy: At least one of the following two sets of conditions was met. FPP1070, diabetic retinopathy level, was coded 060-070. FPP1070, diabetic retinopathy level, has a code of anything other than "012 Non-diabetic retinopathy," and FPP1214, photocoagulation treatment outside arcades, was coded "02 Yes." Moderate/severe non-proliferative retinopathy: FPP1070, diabetic retinopathy level, was coded "041 Moderate non-proliferative" or "051 Severe non-proliferative." Mild non-proliferative retinopathy: FPP1070, diabetic retinopathy level, was coded "020 Microaneurysms only" or "031 Early non-proliferative." No diabetic retinopathy: FPP1070, diabetic retinopathy level, was coded 010-015. "Cannot grade" diabetic retinopathy: FPP1070, diabetic retinopathy level, was coded "088 Can't grade." Blank but applicable: FPP1060, gradability, was coded "06 Entire field ungradable," or FPP1020, fundus, was coded "00 Absent" or "88 Blank but applicable." PHYSICAL FUNCTION EVALUATION Physical function (PF) was evaluated on examinees aged 60 years and over by a trained examiner using a battery of physical performance measures in the mobile examination center (MEC) and at examinees'homes. The protocol for this component did not detail any medical, safety or other exclusions. To determine which sample persons were home examinees, the DMPSTAT variable (3=home-examined) should be used. When analyzing data for combined home-examined and MEC-examined persons, the combined MEC- plus home-examined sample weight should be used (WTPFHX6). When using only MEC items or measures, the MEC examination sample weight should be used (WTPFEX6). For more information on the use of sample weights in NHANES III data analysis, refer to the NHANES III Analytic and Reporting Guidelines (U.S. DHHS, 1996b). Physical function was tested using certain movements that represent musculoskeletal activities needed to carry out daily activities. Gross shoulder joint movement, fine motor hand movement, lower extremity motor functions, and integrated movement of balance and gait were determined. Upper extremity functions were evaluated using Jette and Branch (1984) right and left shoulder, external and internal rotations (PFPRSER, PFPLSER, PFPRSIR, and PFPLSIR). The fine motor function examination was a modification of a manual ability examination in which a key was inserted into a lock and then was turned (PFPTKEY) (Williams, 1982). The lower extremity motor, balance, and gait evaluation items included time to get up from an armless chair five times (PFPTSTND), a full tandem stand with the heel of one foot directly in front of the toes of the other foot for a maximum time of 10 seconds (PFPTTAND), and left and right knee flexing (PFPLFLEX and PFPRFLEX). An eight-foot walk performed twice at the usual walking speed (PFPTWLKA, PFPTWLKB, PFPNSTPA, and PFPNSTPB) was used also (Jette, 1985; Tinetti, 1986; Nevitt, 1989). Items were scored by measuring the time required to perform the maneuver (lock and key, chair rising, tandem stand, eight-foot walk), by using scoring rules (shoulder rotation, knee flexing), and by counting steps (eight-foot walk). Examinees who were unable to perform a specific maneuver either because they felt that it would have been unsafe or because they knew they were unable to do it for reasons related to physical limitations or health conditions were not required to make an attempt. For example, if an examinee was in a wheelchair and was not able to stand up, he/she skipped the following maneuvers: time to complete five chair stands (PFPTSTND), right and left knee-hip flexion (PFPRFLEX and PFPLFLEX), and tandem stand (PFPTTAND). The examinee was then asked, "Are you able to walk alone without holding on to another person? You may use a cane or walker." If he/she answered affirmatively, the examinee did the measured walking (PFPTWLKA, PFPTWLKB, PFPNSTPA, and PFPNSTPB); otherwise, he/she skipped the measured walking and ended the test. In the data set, examinees unable to complete the maneuver for these reasons were coded as "Blank," whereas examinees who did not perform the test for reasons unrelated to physical limitations were coded as "8 Blank but applicable." Persons aged 60 and over who refused or were unable to come to the mobile examination center (MEC) were tested in their homes. Persons found to be bedbound were excluded from the lower extremities part of the PF evaluation (HXPBED). Aside from using an accessible, armless chair in the examinees' homes (HXPCHIR), technicians used equipment and procedures comparable to those used in the MEC. Because technicians used equipment and procedures in examinees' homes that were comparable to those used in the MEC, the home PF values were incorporated into the MEC PF measures data set. Refer to the Physical Function Examination Manual (U.S. DHHS, 1996b) and the Home Examination Manual (U.S. DHHS, 1996b) for descriptions of data collection procedures and methods. At the time of hire, MEC and home examination health technicians were trained to conduct the physical function evaluation. During annual site visits, examination administration was observed, and re-training took place. Applicable parts of the National Institute on Aging video "Assessing Physical Performance in the Home-Part 1" were used to demonstrate the PF procedures during initial training and re-training (NIA, 1988). Data processing and editing were performed to ensure internal data consistency. Notes have been provided for variables requiring additional explanation.
