No. (HSM) 73-1310, Series 1, Nos. 10a and 10b, Public Health Service, Washington, D. C., U. S. Government Printing Office, February 1973. Also provided is a draft report on the augmentation survey of adults describing the relevant field work conducted between July 1974 and October 1975. TARGET POPULATION Target Population: HANES I was conducted on a nationwide probability sample of approximately 32,000 persons, ages 1-74 years, from the civilian, noninstitutionalized population of the coterminous United States, excepting those persons residing on Indian reservations. The survey started in April 1971 and for many survey components was completed in June 1974. The HANES I sample was selected so that certain population groups thought to be at high risk of malnutrition (persons with low incomes, preschool children, women of childbearing age and the elderly) were oversampled at known rates. Adjusted sampling weights were then computed within 60 age, sex and race categories in order to inflate the sample in such a manner as to closely reflect the noninstitutionalized population, ages 1-74 years, of the United States at the midpoint of the survey. Although the main emphasis of HANES I was on nutrition, a subset of those sample persons aged 25-74 received a more detailed health examination which was continued through October 1975. No particular oversampling of subgroups of the population was done in this subsample (e.g., women of childbearing age were not oversampled as they were for the major nutrition component of HANES I). This subsample is also representative of the United States population aged 25-74 during the time of HANES I. After the nutrition survey was completed, the detailed examination given to the 25-74 age group was continued until the total number of examined persons was approximately double the number of examinees who received the detailed examination during the nutrition survey. DATA COLLECTION Data Collection: Information for all examined sample persons in HANES I was obtained by means of a household interview, a general medical history, a 24-hour dietary intake recall interview, a food frequency interview, a food program questionnaire, a general medical examination, dental, dermatological and ophthalmological examinations, anthropometric measurement, hand-wrist x-rays (of those ages 1-17 only) and 24 hematological, blood chemistry, and urological laboratory determinations. In addition to the information received on all examined persons by means of the above questionnaires, procedures and measurements, the following data were gathered on the subsample of adults aged 25-74: a medical history supplement; supplementary questionnaires concerning arthritis, respiratory and cardiovascular conditions (when applicable); a health care needs question- naire; a general well-being questionnaire; an extended medical examination; x-rays of the chest and hip and knee joints; audiometry, electrocardiography; goniometry; spirometry; pulmonary diffusion and tuberculin tests; along with additional laboratory determinations. USE OF HANES DATA With the goal of mutual benefit, NCHS requests the cooperation of recipients of data tapes in certain actions related to their use: A. Any published material derived from the data should acknowledge the National Center for Health Statistics as the original source. It should also include a disclaimer which credits any analyses, interpretations, or conclusions reached to the author (recipient of the tape) and not to NCHS, which is responsible only for the initial data. B. Consumers who wish to publish a technical description of the data will make a reasonable effort to insure that the description is not inconsistent with that published by NCHS. This does not mean, however that NCHS will review such descriptions. ERRORS IN THE DATA SETS AND SURVEY DIFFERENCES The data users' tapes have been subjected to a great deal of careful editing. However, due to the large volume of data in the series, it is likely that a small number of errors or discrepancies remain undetected. We would appre- ciate if any such errors are detected that they be brought to our attention so that new corrected copies of the tape can be created and errata sheets issued to previous purchasers. Some of the continuous data items have extremely high or low values and we have verified that they do in fact appear that way on the hard documents; that is, we have verified that the values have not been incorrectly keyed. In general, we have not attempted to resolve any differences that may exist between estimates derived from the various subsamples of HANES I. Nor have we made any comparisons between estimates from HANES I and previous surveys conducted by the Division of Health Examination Statistics. VARIANCE ESTIMATION Because the Health and Nutrition Examination Survey is based upon a complex sample design, the assumptions of many statistical tests and routinely avail- able statistical programs are not met. For this reason, when estimates of the variances of statistics from HANES are computed, the technique of estimation must be based upon complex sampling theory. In order to provide the user with the capability of estimating the complex sample variances, we have provided Strata and Primary Sampling Unit (PSU) codes on the HANES user tapes in tape positions 194-198. However, these codes are suitable for making variance estimates only for examination locations 1-65 and 1-100. To compute variance estimates for examination locations 1-35 or 66-100, it is necessary to recode the current Strata-PSU codes according to the specifications that follow. The resultant recoded Strata-PSU codes should be used only for locations 1-35 and 66-100. One computer program that should be widely available sometime around the summer of 1978 as part of the Statistical Analysis System (available from the SAS Institute, Inc., Post Office Box 10066, Raleigh, North Carolina 27605) is capable of using the Strata-PSU codes provided for HANES to compute complex sample variances. Other programs may also be available. In those Strata, referred to as certainty or self-representing Strata, the PSU codes are actually the segment numbers. Neither the Strata codes nor the PSU codes are the original codes used in the formation of the HANES sample design, but are nonetheless a unique Recoding of the original codes. For further discussion of the sample design of HANES, the user should consult the publications of the National Center for Health Statistics--Series-Nos. 10a and 14 and the detailed note for tape positions 158-193. Recode Specifications for Strata-PSU Codes First.--Create a files with only those records in the file for examination locations 1-35.* Second.--Retain 1he original Strata-PSU codes in Strata 7-10 and 13 in the original form as the recoded Strata-PSU codes. Third.--Recode the remaining strata according tot he chart below. Fourth.--Repeat the process for examination locations 66-100.* Old Strata # (tape positions 194-195) New Strata # New PSU 01 01 001 02 01 002 03 03 001 06 03 002 04 04 001 05 04 002 11 11 001 12 11 002 14 14 001 21 14 002 15 15 001 16 15 002 17 17 001 20 17 002 18 18 001 19 18 002 22 22 001 25 22 002 23 23 001 24 23 002 26 26 001 27 26 002 28 28 001 29 28 002 30 30 001 35 30 002 31 31 001 32 31 002 33 33 001 34 33 002 *See detailed note for tape positions 158-193. GENERAL NOTES, DEMOGRAPHIC DATA, HANES I Demographic Information: An advance letter, announcing the forthcoming arrival of an interviewer from the U. S. Bureau of the Census, was mailed to each household that fell into the sample area. The interviewer subsequently visited the household to ascertain its composition and to administer a questionnaire, the primary purpose of which was to obtain demographic information. The questionnaire was administered to each potential sample person that was available and competent enough to respond to questions. In the event that a potential sample person was not at home at the time of interview, any responsible adult in the household was asked to respond to the questions for the absent person. Asterisks on the Tape Description: Some of the data items were obtained only for a particular subsample of HANES. Consequently some of these items appear to have a great deal of missing data (coded as blank) due to nonresponse, but in fact the data are missing because the design of HANES dictated that the item was to be obtained only for a particular subsample. (For further discussion of the various subsamples in HANES the user should see the detailed note for tape positions 158-193.) To alert the user to this fact asterisks were put on the tape des- cription. One asterisk denotes that the data item was obtained only on examinees at locations 1-65, two asterisks denote that it was ob- tained only at location 66-100 and three asterisks denote that it was obtained only on examinees receiving the detailed examination.

DETAILED NOTES, DEMOGRAPHIC DATA Tape Position 10 - Size of Place Size of place classification was derived from the 1960 census. According to the definition used in the 1960 census, the urban population was comprised of all persons living in (a) places of 2,500 inhabitants or more incorporated as cities, boroughs, villages and towns (except towns in New York, New England, and Wisconsin); (b) the densely settled urban fringe, whether incorporated or unincorporated, or urbanized areas; (c) towns in New England and townships in New Jersey and Pennsylvania which contained no incorporated municipalities as subdivisions and had either 2,500 inhabitants or more, or a population of 2,500 to 25,000 and a density of 1,500 persons or more per square mile; (d) counties in states other than the New England states, New Jersey, and Pennsylvania, that had no incorporated municipalities within their boundaries and had a density of 1,500 persons per square mile; and (e) unincorporated places of 2,500 inhabitants or more not included in any urban fringe. The remaining population was classified as rural. Urban areas are further classified by population size for places within urbanized areas and other places outside urbanized areas. Tape Position 11 - SMSA A standard metropolitan statistical area is basically a county or a group of contiguous counties which contains at least one city of 50,000 inhabitants or more, or "twin cities" with a combined population of at least 50,000. In addition to the county or counties containing such a city or cities, contiguous counties are included in an SMSA if, according to the 1960 Census, they are socially and economically integrated with the central city. Each SMSA must include at least one central city, and the complete title of an SMSA identifies the central city or cities. Tape Positions 22 and 103 - Race The race of the respondent was marked by observation and it was assumed the race of all related persons was the same as the respondent unless otherwise learned. The race categories were "White", "Negro", or "other." If the appropriate category could not be marked by observation, then race was asked. Persons of races other than White or Negro, such as Japanese, Chinese, American Indian, Korean, Hindu, Eskimo, etc. were reported as "Other." Mexicans were included with "White" unless definitely known to be American Indian or of other nonwhite race. Tape Positions 34-35 - Total Family Income Group The income group represents the total combined family income for the past twelve (12) months. It includes income from all sources such as wages, salaries, social security or retirement benefits, help from relatives, rent from property and so forth. The income groups were not reconciled to the component parts (tape positions 36-94). The income component parts were not asked when the gross income was greater than $6,999 per annum. However, amounts greater than $6,999 appear in tape positions 37-40, 67-70, and 72-75. Some respondents reported a loss of income from their nonfarm business, professional practice, partnership or farm and this explains why some data fields are greater than $6,999, but the individual total in tape positions 91-94 does not exceed this figure. Tape Positions 95-99 - Family Unit Code All related sample persons in the same family unit have the same computer generated family unit code. This will enable detailed analysis of the individual family unit.

For this survey purpose, the principal job or business of a respondent is defined in one of the following ways: If the person worked during the two week interview period or had a job or business, the question concerning his occupation (or work) applies to his job during that period. If the respondent held more than one job, the question is directed to the one at which he spent the most time. It refers to the one he considers most important when equal time is spent at each job. A person who has not begun work at a new job, is looking for work, or is on layoff from work is questioned about his last full- time civilian job. A full-time job is defined as one at which the person spen 35 or more hours per week and which lasted two consecutive weeks or more. A person who has a job to which he has not yet reported and has never had a previous job or business is classified as a "new worker." The 1970 census of population Alphabetical Index of Industries and Occupations was used in the coding of both the industry and occupation. Library of Congress Number 74-612012.

Tape Position 146 - Land Land used for farming purposes (Code 1 in Tape Position 146) was identified as being rural land (Code 2 in Tape Position 13) consisting of 10 or more acres (Code 1 in Tape Position 14) with crop sales amounting to $50 or more (Code 2 in Tape Position 15), or rural land (Code 2 in Tape Position 13) consisting of less than 10 acres (Code 2 in Tape Position 14) with crop sales amounting to $250 or more (Code 3 in Tape Position 16). All Other land is classified as nonfarm (Code 2 in Tape Position 146). Tape Positions 147-149 - Poverty Index Poverty Index--Income status was determined by the Poverty Income Ratio (PIR). Poverty statistics published in the Census Bureau reports1/ were based on the poverty index developed by the Social Security Administration in 1964. (For a detailed discussion of the SSA poverty standards, see reference 2.) Modifications in the definition of poverty were adopted in 1969.3/ The standard data series in poverty for statistical use by all executive departments and establishments has been established.4/ The two components of the PIR are the total income of the household (numerator) and a multiple of the total income necessary to maintain a family with given characteristics on a nutritionally adequate food plan3/ (denominator). The dollar value of the denominator of the PIR is constructed from a food plan (economy plan) necessary to maintain minimum recommended daily nutritional requirements. The economy plan is designated by the Department of Agriculture for "emergency or temporary use when funds are low." For families of three or more persons, the poverty level was set at three times the cost of the economy food plan. For smaller families and persons living alone, the cost of the economy food plan was adjusted by the relatively higher fixed expenses of these smaller households. The denominator or poverty income cutoff adjusts the family poverty income maintenance requirements by the family size, the sex of the family head, the age of the family head in families with one or two members, and the place of residence (farm, nonfarm). Annual revisions of the poverty income cutoffs are based on the changes in the average cost of living as reflected in the Consumer Price Index. As shown in the table, the annual income considered to be the poverty level increases as the family size increases. A family with any combination of characteristics and with the same income as shown in the table has been designated as having a PIR or poverty level of 1.0. The same family with twic the income found in the table would have a PIR of 2.0. Ratios of less than 1.0 can be described as "below poverty," ratios greater than or equal to 1.0, as "at or above poverty." Poverty thresholds are computed on a national basis only. No attempt has been made to adjust these thresholds for regional, State, or other local variation in the cost of living (except for the farm, nonfarm difference). None of the noncash public welfare benefits such as food stamp bonuses or free food commodities are included in the income of the low income families receiving these benefits. 1/ Current Populatrion Reports, "Consumer Income," Series P-60, No. 77, May 7, 1971 2/ Orshansky, M.: "Counting the Poor: Another Look at the Poverty Profile, Social Security Bulletin, January 1965; "Who's Who Among the Poor: A Demographic View of Poverty," Social Security Bulletin, July 1965. 3/ Current Population Reports, "Special Studies," Series P-23, No. 28, August 12, 1969 4/ Circular No. A-46, Transmitted Memorandum No. 9, Executive Office of the President, Bureau of the Budget, August 29, 1969, and Exhibit L (rev.)

Tape Position 150 - Region The United States was divided into four broad geographic regions of approximately equal population. These regions, which deviate somewhat from the groups used by the Bureau of the Census, are as follows: Region States Included Northeast Maine, Vermont, New Hampshire, Massachusetts, Connecticut, Rhode Island, New York, New Jersey, and Pennsylvania South Delaware, Maryland, District of Columbia, West Virginia, Virginia, Kentucky, Tennessee, North Carolina, South Carolina, Georgia, Florida, Alabama, Mississippi, Louisiana, and Arkansas Midwest Ohio, Illinois, Indiana, Michigan, Wisconsin, Minnesota, Iowa, Missouri West Washington, Oregon, California, Nevada, New Mexico, Arizona, Texas, Oklahoma, Kansas, Nebraska, North Dakota, South Dakota, Idaho, Utah, Colorado, Montana, and Wyoming. Tape Positions 158-193 - HANES HANES is a multistage, stratified, probability sample of loose clusters of persons in land-based segments. In addition, HANES is composed of two distinct examination components--a nutrition screening examination (taken by all examinees) and a more detailed examination taken by a pre-selected subsample of all examinees, ages 25-74. For the nutrition screening examination, locations 1-35 and 1-65 constituted national probability samples and for the detailed examination, locations 1-35, 1-65, 66-100 and 1-100 all constitute national probability samples. In other words, HANES is composed of six distinct subsamples of the U.S. population. For a more detailed discussion of the sample design see Series 1, No. 10a. Since each of these six subsamples is a distinct subsample of the U.S. population, such subsample requires a different set of weights. The weights are based upon the probability of selection into the sample, adjustments for nonresponse and further adjustments to approximate the U.S. noninstitu- tionalized population as of the midpoint of each subsample. In order to select all of those examinees in a particular subsample, i.e. received a particular exam component, it is necessary to exclude all examinees with a weight of zero or blank. It is also necessary to exclude all zero or blank weights because that is the only way to differentiate missing data due to nonresponse from data that is missing because the sample design dictated that a particular examinee was not supposed to receive particular examination component. It is suggested that any analyses that are desired by the researcher be per- formed using the greatest number of examinees possible; that is, if the researcher is interested in an exam component of the nutrition screening examination he should use the weight and consequently the data from the 65 location subsample rather than the 35 location subsample. For the detailed examination, the researcher should use the 100 location subsample rather than one of the others. However, some exam components were only done in a particular subsample; for example, only at the first 35 locations. In that case, the researcher has no choice in selecting a particular subsample. There may be occasions when a researcher may want to make comparisons of estimates obtained from various subsamples. For example, the prevalence of some disease condition as estimated from the first 35 locations could be compared with an estimate based upon locations 66-100. The researcher may also want to formulate hypotheses using 1 subsample and test those hypotheses using another subsample.

The technician then again traced the lung perimeters using the magnifying tracer of the planimeter. This data was interpreted by a Numonics model 1224 electronic digitizer, and areas were read and recorded from the display console. Thoracic diameters -- The PA diameter, given in centimeters, was the maximum transverse diameter of the chest on the PA film, as measured by the Numonics digitizer.The first and second lateral diameters were the least distance in centimeters from the superior and inferior posterior margins of the eighth thoracic vertebrae to the posterior margin of the sternum, respectively. Measurements were made with the Numonics digitizer.Thoracic diameters were not measured for examinees in the Augmentation Survey. Tracheal diameters - Tracheal diameters were measured at the levels of the superior borders of the second (T2) and the third (T3) thoracic vertebrae. Measurements were made with a straight edge and a square. Using a straight edge, the tracheal borders at the levels of T2 and T3 were marked. These lines were extended so as to best parallel their respective tracheal walls.A perpendicular to the right tracheal border was established with a square at the superior border of T2 and T3. Measurement of the distance between tracheal walls was measured along this perpendicular with a Fowler caliper,and readings were recorded to the nearest hundredth of a centimeter. Tracheal diameters were not measured for examinees in the Augmentation Survey. Tape Positions 238-257 - Heart Size Measurement Techniques Five measures of heart size were taken for each examinee in order to assess cardiac pathology and heart enlargement, using techniques suggested by Grover et al in Circulation, Volume XLVII, June 1973. As described in the article, the technician used a straight edge and pencil to establish a transverse line horizontally across the posterior-anterior (PA) x-ray between the pair of ribs (left and right) which defined the maximum intra-thoracic diameter. The distance between the internal margins of these sites,B1 and B2,defined the maximum transverse diameter of the thorax. A second line was drawn perpendicular to the first line, bisecting the chest into left and right halves. The technician then identified the points, one on the left and one on the right, which marked the most lateral cardiac margins. Another perpendicular was drawn from each of these points to the transverse thoracic line. The distance between point A1 (where the perpendicular from the left cardiac border intersected the transverse line) and the point A2 (where the perpendicular from the right cardiac border intersected the transverse thoracic line) was measured and recorded.This distance,A1 to A2,defined the maximum cardiac diameter on the PA film.The technician then marked the point that identified the junction of the right atrium and the superior vena cava, C1 and the point that marked the cardiac apex, C2.The distance between these two points was measured and recorded.The right cardio-phrenic angle,D1, was then identified,as well as the junction of the atrial appendage with the main pulmonary artery, D2.This distance, representing the cardiac broad diameter, was measured and recorded. The technician then marked a horizon- tal line on the lateral chest x-ray which transected the heart at its widest diameter.The points where the line intersected the anterior and posterior cardiac shadow were identified,and this distance was measured and recorded as the greatest cardiac diameter on the lateral film, E1 to E2. Tape Positions 258-322, 323-387, 388-452-Cardiopulmonary Findings In order to be able to determine the presence or absence of cardiopulmonary findings, a recording form was developed by the principle contract x-ray reader and the NHANES medical advisor. Since structural abnormalities can directly or indirectly influence pulmonary mechanics, the forms were expanded to include the presence of scoliosis, kyphosis, pectus, and rib fractures. The forms were structured to permit: 1) grouping of abnormalities by location or system - e.g., chest wall, pulmonary, lymphatic, pleural, and cardiovascular, 2) assessing the extent of the abnormalities (e.g., size and number of nodules) and distribution (e.g., segmental and nonsegmental infiltrates) of the disease, 3) suggesting etiologies (e.g., infections as the cause of nodules; pneumonoconiosis as the cause of pulmonary infiltrates) when sufficient information was available from the x-ray, and 4) recording into "open" recording space those observations and abnormalities which did not otherwise fit into the coded form. The assessment as to whether the nonsegmental nonhomogenous infiltrates were minimal, moderate or advanced was made according to the Diagnostic Standards and Classification of Tuberculosis (National Tuberculosis and Respiratory Disease Association, New York, NY 1969). Objective criteria concerning the other findings to be assessed were not available at the time the form was designed. The final report of the contractor responsible for making all heart size and lung measurements and all assessments for cardiopulmonary pathology is available to interested parties. In addition, a portion of that final report has been excerpted and is included as Appendix I to this document. In the excerpted portion,the contractor has provided assessments of the validity and usefulness of each of the individual pathology findings presented in this data set, as well as descriptions of problems encountered in the reading and evaluation process.Users of this data set are advised to review the excerpt prior to conducting any analyses of these data. Tape Positions 259, 324, and 389 - Kyphosis Findings related to kyphosis were not formally recorded for subjects who received the detailed examination during that part of NHANES I conducted from 1971 to 1974.Consequently, no response is coded for those 3854 subjects. For some of those subjects an observation of kyphosis was recorded in the "Comments" section of the coding form, but the observations were not consistently recorded. In addition, a number of subjects did not receive a lateral x-ray, and for these examinees the assessment of kyphosis was not reliable. Tape Positions 274-293, 339-358, 404-423 - Nodules Review of the coding form used for the part of NHANES I conducted in 1971-74 prompted a revision of the section relating to nodules prior to the Augmentation Survey conducted in 1974-75. In particular, the lung(s) and specific lobe(s) of the lung(s) in which the largest and second largest nodules were located are only coded for subjects examined in the Augmentation Survey. The relative location(s) of the largest and second largest nodules are only coded for subjects examined in 1971-74.The coding schema are approximately equivalent, except that the schema used for the subjects of the Augmentation Survey provides substantially more detail than that used for the examinees receiving the detailed examination in 1971-74. Tape Positions 294-304, 359-369, 424-434 - Infiltrates Review of the coding form used for the part of NHANES I conducted in 1971-74 prompted a revision of the section relating to infiltrates prior to the Augmentation Survey conducted in 1974-75.In particular,more detailed coding schema were developed for the specific lobe in which localized segmental infiltrates were located, and for the severity of diffuse nonsegmental nonhomogenous infiltrates. In each case the less specific schema can be derived by combining adjacent categories of the more specific schema. Tape Positions 388-452 - Pathology Final Readings Reader opinion represents a useful assessment of radiographic abnormalities. For example, Nicklaus et al (American Review of Respiratory Disease 93: 889-899, 1966) have shown that reader opinion is the best way to diagnose moderate to severe emphysema from the chest x-ray and that it correlates well with histologic findings.Hence, the present study utilized reader opinion to assess the presence or absence of heart and lung pathology. Because such opinion has been shown to have appreciable inter-observer and intra-observer error, two independent readers were utilized to establish the presence or absence of pathology. The pathology final readings do not represent a third reading of each x-ray, but instead a synthesis of the first two readings. The x-rays of those subjects examined in 1971-74 (the General Nutrition examination) were only read once,so that for those examinees the final reading is simply a copy of the first reading. The x-rays of those subjects examined in the Augmentation Survey (conducted in 1971-74) were read twice by independent readers.When the findings of the two readers agreed, the final reading is a copy of those findings. When the readers disagreed in any particular, the film was subjected to adjudication,in which the readers jointly reviewed the film and came to agreement on the disputed item(s).In a few cases,disputed films were referred to a third expert reader for adjudication. In this study, Dr. Lanie Eagleton, Associate Professor of Medicine and Chief of the Pulmonary Division of the Southern Illinois University School of Medicine, performed all the first readings.The "second" reader was one of four radiology residents at the Southern Illinois School of Medicine.Expert judgment on disputed films was provided by Dr. William Sherrick, a staff radiologist at the Southern Illinois School of Medicine specializing in chest radiology. Tape Positions 501-532 - Pulmonary Diffusion Measurements of single breath carbon monoxide diffusion capacity were per- formed on all detailed examinees using a Collins modular lung analyzer. This machine provides basic data from which estimates can be made of the rate of diffusion of gases across the pulmonary membranes. Each examinee who the physician did not disqualify performed first a Forced Expiratory Spirogram to establish his forced vital capacity and then three trials on the lung analyzer. Each trial consisted of: 1) a maximal inspiration of a gas mixture containing air,10 percent helium (He), and 0.3 percent carbon monoxide (CO), followed by 2) breathholding for about 10 seconds, and finally 3) as complete and rapid an expiration as the examinee could perform. The expired gas was analyzed for the proportions of expired He and CO. Trials were separated by rest periods of at least five minutes. Each trial and the entire test was subjected to a variety of quality control criteria, including: 1) Inspired volumes must be at least 80 percent of forced vital capacity. 2) Inspiration times must be less than three seconds. 3) Breathholding times must be between 8.5 and 11.5 seconds. 4) Expired gas samples must be at least 500 ml. 5) The volumes of inspired gas must not decrease more than 200 ml during breathholding. 6) The trials must be free of inhalation artifacts. 7) Expired CO and He measurements must not differ by more than 10 percent. Calculations of pulmonary diffusion capacity (DLCO) were performed at the end of the survey for all trials that were free of quality control violations, using the following formula: DLCO = (IVC * HEI / HEE - Weight in pounds - 75) * STPD factor * (192 / Breathholding time) * (1 / (BP - 47))* In ((COI / COE) * (HEI / HEE)) where: IVC = Inspired vital capacity HEI, HEE = Inspired and expired helium concentration STPD = Standard Temperature and Pressure correction factor BP = Uncorrected barometric pressure COI, COE = Inspired and expired carbon monoxide concentration A summary DLCO was also derived. The summary was the average of all DLCO's that were within 10 percent of the largest, or the largest alone if reproducibility had not been demonstrated or if only one trial was available. Tape Positions 551-563 - Tuberculin Test Each adult ages 25-74 years selected in the sample for the more detailed examination was given a tuberculin skin test as part of the examination component relating to respiratory conditions.Due to the difficulty in getting the examinees to return to the examining center 48-72 hours after receiving their tuberculin tests for reading, tuberculin tests were only to sample persons in stands 1-35. Examinees who had a history of a positive reaction, tuberculosis, Isoniazid prophylaxis or who were examined a day or two before the mobile examination unit was scheduled to move were not given the tubercu- lin skin tests. Simultaneous skin testing with PPD-S tuberculin antigen and PPD-B antigen permitted differentiation between reactivity caused by infection with M. tuberculosis and the other mycobacteria. Trained staff nurses administered 5 tuberculin units contained in 0.1 cc solution into the left arm and 5 units of PPD-B in 0.1 cc solution into the right arm.Both antigens used in the survey examinations were obtained from the Tuberculosis Program of the Centers for Disease Control, Public Health Service.The tuberculin skin tests were read 48-72 hours after injection. The indurated area was measured to the nearest millimeter at its widest transverse diameter. Further description of the tuberculin tests may be found in "Tuberculin Skin Test Reaction Among Adults 25-74 Years1". 1National Center for Health Statistics, A. Engel and J. Roberts: Tuberculin Skin Test Reaction Among Adults 25-74 Years, by Vital and Health Statistics. Series 11-No. 204. DHEW Pub. No. (HRA) 77-1649. Public Health Service. Hyattsville, Md. July, 1977. Quality Control When the reading and evaluation of the x-rays in this data set was initiated, objective criteria did not exist to assess the presence or absence or degree of significance for many of the fields reported in the section relating to cardiopulmonary pathology. After review of this data set by staff members of the National Center for Health Statistics,and in light of the comments raised by the primary contract reader, several studies were initiated to validate selected items from the data set.Cobb's angles were measured for all subjects with a positive findings for scoliosis (see Carter, O.D., and Haynes, S.G.: Prevalence rates and risk factors for scoliosis in U.S. adults: Results from the First National Health and Nutrition Examination Survey (NHASES I). In Preparation). The right descending pulmonary artery was measured for all subject with a positive finding for pulmonary artery enlargement (as well as for a sample of subjects who did not have positive findings) by an acknow- ledged expert in that condition,and the results are currently being anlayzed to determine proportion of false positives and negatives.Finally, all x-rays reported to show some pleural disease have been re-read by an expert in that condition, and these data are also currently being analyzed. Users may wish to consider conducting validation studies of their own prior to pursuing specific analyses.Under certain restricted circumstances, it is possible to obtain from NCHS selected subsets of x-rays from the original data set to conduct such studies.Contact Terence Drizd or Dr.Suzanne Haynes of the Medical Statistics Branch, Division of Health Examination Statistics, NCHS for more information. APPENDIX I: EXCERPT FROM FINAL REPORT OF CONTRACT X-RAY READER Kyphosis, a subjective evaluation, was a source of disagreement between readers. The data should not be used as free standing prevalence data. However,the adjudicated data should prove useful for comparison with and for assessment of other pulmonary data, e.g., spirometry and physical examina- tion data. Scoliosis was a frequent finding. Most of the differences of opinion as to the presence or absence of scoliosis occurred when there were small angula- tions which had not been recorded by one of the readers.The data should be further refined by having the angles of the scoliosis measured so that the data become quantitative as well as qualitative.This data is of good quality as a source of prevalence estimates as well as a source of comparison with spirometric abnormalities. Pectus excavatum, a subjective evaluation, was a source of substantial disagreement between readers. Since this abnormality has been linked to diaphragmatic abnormalities,it is an important finding to compare with the other data, e.g., spirometry and physical examination findings.It should not be used as a source of prevalence estimates for pectus excavatum. Nodules were the most common abnormality. They were divided into those the reader believed were: 1) nipple shadows, 2) extra-pulmonary densities, 3) radio-dense or calcified lesion judged to be secondary to a remote granulatomous infection, such as a fungal infection, a viral infec- tion, or tuberculosis, and 4) "other" nodules which had a reasonably high probability of represen- ting a neoplasm, a tumor of non-infectious etiology,or an infectious disease which had been recently acquired. The nipple shadows and the extra-pulmonary nodules were recorded because they were potential sources of error in identification of pulmonary nodules. This recording was helpful in editing and adjudicating. It should not be used for prevalence estimates and was not meant for correlation with the other pulmonary data. The sizes of the intrapulmonary nodules were recorded in millimeters. The nodules were frequently asymmetrical. The measurement instructions were not explicit as to how to measure an asymmetric nodule. Hence, the two readings were frequently different by a few millimeters - usually no more than two. However, this small difference in reading resulted in the x-rays being re- called for adjudication.The difference was resolved by reader #1 remeasuring the nodules and adjudicating the reading to the maximal diameter of the nodule. This consumed a large amount of time. However,the final data on the prevalence and the size of the nodule is good data for publication. The enumeration of the nodules presented problems,particularly when the densities near the hilum could be interpreted as either a vessel or a nodule.When there was a difference of opinion as to whether a nodule was present or absent,the lesions were adjudicated as not present. The data on the number of nodules present should prove useful for assessing the extent of the inflammatory process in the lung. The coding of the abnormalities by utilizing the smallest lung divisions which were likely to encompass the lesion, (e.g., a segment of the lung) presented a problem with adjudication. Precise anatomical location is difficult to establish from x-rays even when both posterior-anterior and lateral films are available. Furthermore, because of the variation in the size of the nodules discussed above, the positions of the nodules were frequently translocated because of differences in ranking of the size of the nodules. This difference in segmental locations was arbitrarily resolved by reader #1 after remeasuring the nodules and re-ranking them according to their maximal diameter. However, the data on segmental location is not sufficiently precise to permit publication as free standing data. Yet, the data should prove useful in planning future surveys, as well as in analyzing distribution of the abnormalities into the regions of the lungs such as left versus right or upper versus lower. The etiology of the nodules represents a judgement on the part of the readers, and it proved to have reasonable inter-reader agreement. The prevalence of post-inflammatory nodules was impressive. This data should prove useful in assessing whether extensive inflammatory nodules of the lung such as one sees in histoplasmosis have an appreciable effect on pulmonary mechanics. For the nodules which were judged to non-infectious, this data establishes an upper limit that one could expect in utilizing x-rays and evaluating the prevalence of abnormalities such as carcinoma of the lung. There was very good agreement between the readers as to the presence of pulmonary infiltrates.However, the readers varied as to how they coded a given infiltrate. Platelike atelectasis presented a particular problem in coding. This abnormality was coded by some as a nonhomogenous, nonsegmental lesion;by others as a homogeneous symmetrical lesion;and by others as "other" with a comment of platelike atelectasis. Because this is a frequent abnormality in the lung,future coding forms should have an independent space for coding platelike atelectasis. Co-existence of a diffuse nonhomogeneous, nonsegmental pulmonary infiltrate (which would be compatible with a previous tubercular or fungal infection) and a more diffuse nonhomogeneous,nonsegmental infiltrate was a frequent source of coding problems. Some readers coded this abnormality as a nonhomogeneous and as a symmetrical infiltrate of the lung. Other readers coded the infiltrates as both a nonhomogeneous nonsegmental and a homogeneous segmental infiltrate, emphasizing that there were components of both distributions present.It is my impression that these two lesions frequently co-exist and are both related to a previous tubercular or fungal infection -the major local infections causing the homogeneous and symmetrical infiltrates and the long-standing spread of antigen diffusely in the lung by bronchogenic spread leading to a more homogeneous and symmetrical infiltrate which is probably a fibrosis in the lung. Future recording forms should have an additional code which permits the reader to record this observation without entering the homogeneous and symmetrical infiltrate as an independent observation,or the coding directions should be explicit as to how to make independent judgements as to whether there were two components to the infiltrate in the lung. The assessment as to whether the nonhomogeneous,nonsegmental infiltrates were either minimal, moderate or far advanced, according to the former NTRDA classification (Diagnostic Standards and Classification of Tuberculosis, National Tuberculosis and Respiratory Disease Association, New York,NY,1969) did not present unusual problems. This is a useful assessment and should permit comparing the extent of the radiographic lesion with the severity of the pulmonary function abnormalities and with the presence or absence of pulmonary symptomatology. In contrast,there was much inter-reader disagreement in assessing whether the homogeneous, symmetrical infiltrates were extensive by making judgement as to whether 1/3, 2/3 or the entire lung was involved.This data should not be used for publication. However,it could be used for comparison with assessments of the severity of the impairment by spirometry and other pulmonary data. If these prove to correlate well, then this assessment might be further refined for use in future surveys by refining the coding instructions. Assessing whether emphysema was present and whether the diaphragms were flat was subjective.The coding instructions were not explicit on criteria to use for judging the diaphragms as flat.The failure of all the readers, except a single one of the second readers using a blank rather than a code of 8 to signify the absence of findings,was the major source of recorded differences. However, when this variability had been edited, and the reading adjudicated, the result in assessment of the prevalence of these findings represents a reasonable assessment for publication.This prevalence of findings on x-rays underestimates the prevalence of emphasyma. It has been previously reported (Am. Rev. Resp. Dis. 42: 889-899, 1966) that this is not useful in detecting milk to early stages of emphysema. The data should be quite useful for use in conjunction with other pulmonary data, including the findings on physical examination, spirometry, carbon monoxide diffusion, and the size of the lungs as assessed by planimetry. It represents confirmatory evidence for the presence of emphysema. In future surveys, there should be criteria in the instructions for assessing whether diaphragms are flat. Calcified lymph nodes were prevalent. Instances where only one reader thought a lesion was present were adjudicated as absence of this finding.Lesions that were calcified and large were frequently recorded as only calcified and not as enlarged.Enlarged nodes which were calcified were adjudicated to be recorded only as "calcified nodes." Difficulties in coding pleural disease were presented by thickening of the pleura of the apex of the heart and of the lung. These were findings which some readers did not code because they were frequent and considered normal. In the adjudication procedure, if these pleural abnormalities were marked and thought to represent an extension of significant pulmonary disease, they were coded as abnormalities.In respect to the pleural findings, these x-rays have been reexamined as a subset to review for pneumonosis. This data should be useful in judging the extent and etiology of the pleural disease and repre- sents an independent judgement by a panel of experts on pleural disease. Those x-rays that had a cardiovascular abnormality checked - azygous vein, right atrial and right ventricular enlargement, cephalization, interstitial fluids, Kerley lines, rosettes, alveolar fluid, and left atrial and left ventricular enlargement, should be reevaluated by a panel of cardiac experts to assess the nature of the cardiac abnormality.I believe the data that has been collected is a useful screen for the presence or absence of abnormality of the cardiovascular system but should not be used to report prevalence of either left or right ventricular disease. The pulmonary artery enlargement assessment was made by subjective evaluation. When both readers on the initial evaluation concurred as to the presence of the pulmonary artery abnormality,that should be used as a lower limit of the abnormality in the population. A more explicit criteria for judgment of pulmonary artery enlargement should be developed and all x-rays positive for this finding should be answered by these criteria.The current data should be useful to compare with other pulmonary observations,but should not be used as free standing data for estimating the prevalence of pulmonary hypertension. Those x-rays that were coded as showing pulmonary artery enlargement could be utilized as subsample for further evaluation by a panel of experts in pulmonary vasculature disease.
