 the documentation herein, and a general summary of the data collection
 techniques and content is given in Appendix A.
DESCRIPTION OF POPULATION

 NHANES II was conducted on a nationwide probability sample of approximately
 28,000 persons, ages 6 months-74 years, from the civilian, noninstitutionalized
 population of the United States. The survey started in February 1976 and was
 completed in February 1980. The NHANES II sample was selected so that certain
 population groups thought to be at high risk of malnutrition (persons with
 low incomes, preschool children and the elderly) were oversampled. Adjusted
 sampling weights were then computed for 76 age, sex,and race categories in
 order to inflate the sample in such a manner as to closely reflect the
 estimated civilian noninstitutionalized U.S. population ages 6 months-74
 years at the midpoint of the survey (March 1, 1978).
DATA COLLECTION TECHNIQUES AND CONTENT

 The plan developed with respect to the content of NHANES II called for the
 following:
    A.  Questionnaires completed in the household:
        (1)  Household questionnaire:  For each household member, questions
             referred to family relationships;certain demographic items such
             as age, sex, and race; selected housing information;occupation,
             income, education, veteran status; and an indication of
             participation in food stamp programs.
        (2)  Medical history questionnaires:
             (a)  For each sample person ages 6 months-11 years
                The questionnaire included items on birth weight,
                prematurity,congenital conditions, medication, neurological
                conditions, lead poisoning, accidents, hospital care,
                disability, diarrhea, pica, vision, and a variety of chronic
                conditions.  In addition, data were collected on allergies,
                kidney and bladder disease, anemia, speech and hearing, lung
                and chest conditions, and participation in food programs.
             (b)  For each sample person ages 12-74 years
                The questionnaire included items on medication; hospital
                care; tuberculosis; a variety of acute and chronic diseases;
                tobacco usage, physical activity; weight; height; vision
                disability, exposure to pesticides; gastrointestinal
                problems; and for females; a menstrual and pregnancy
                history.  In addition, data were collected on anemia,
                diabetes, respiratory condition, hearing and speech, liver
                and gallbladder conditions, kidney and bladder disease,
                allergies, hypertension, cardiovascular conditions, stroke,
                arthritis (stressing middle and upper back and neck
                problems), and participation in food programs.
        Questionnaires and tests administered in the mobile examination
        center:
        (3)  Dietary Questionnaires
           (a)  For each examined person, a 24-Hour Recall was administered
                by trained dietary interviewers.  Specific and quantitative
                detail of every food or drink consumed during the previous
                day was recorded and calculated, thus providing estimates of
                calories, protein, carbohydrates, fat, unsaturated fats,
              cholesterol, and specific vitamins and minerals consumed.
           (b)  For each examined person, a Food Frequency interview was
                administered to ascertain usual patterns of food consumption.
                Daily and/or weekly consumption of foods within 26 subgroups
                were recorded.  In addition, data were collected on usual
                vitamin-mineral supplement usage.
           (c)  For each person ages 12-74 years, a Dietary Supplement form
                was self-administered and reviewed.  This form provided
                information on special diets, recent medications and barriers
                to purchasing groceries or eating foods; it does not provide
                information on vitamin/mineral or other supplements to the
                diet.
        (4)  Medication/Vitamin Usage Form provided information on the past
             week's usage of any medicines; vitamins or minerals for al
             examined persons.
        (5)  Behavior Questionnaire elicited data on behavior which may be
             associated with coronary heart disease for examined persons
             ages 25-74.
             B.  Examination by physician
                 A physician performed and recorded the results of a medical
                 examination giving special attention to specified findings
                 related to nutrition, to hearing, to the thyroid gland,and
                 to the cardiovascular, respiratory, neurological and
                 musculoskeletal systems.
             C.  Special clinical procedures and tests
                 A specially trained health technician carried out the
                 following on examined persons in the designated age ranges:
                 1.  Spirometry trials of examined persons ages 6-24 years,
                   were digitized and recorded on magnetic tape.  Various
                   pulmonary function indicators such as FVC (forced vital
                   capacity), FEV1 (forced expiratory volume in one second),
                   and peak flow rate were subsequently derived from these
                   data.
               2.  Electrocardiograms Electrocardiographic signals of
                   examined persons ages 25-74 years were digitized and
                   recorded on magnetic tape providing normative data of
                   amplitude, duration, interval and axis measurements and
                   permitting interpretations of heart disease according to
                   the Minnesota classification code.
               3.  Body Measurements were made on all examinees and included
                   standing height, body weight, triceps and subscapular
                   skinfolds, and several other anthropometric measurements.
               4.  Puretone audiometry Tests were carried out on examined
                   persons between the ages of 4 and 19 years, permitting
                   determination of threshold levels of hearing for
                   frequencies of 500, 1000, 2000, and 4000 Hertz for right
                   and left ears.
               5.  Speech recording, involving use of tape recording of the
                   subject's repetition of specially developed sentences,was
                   carried out on examined persons between the ages of 4 and
                   6 years, permitting interpretations as an indication of
                   problems with articulation and language development.
               6.  Allergy tests, involving skin tests (prick test) with
                   eight common allergens (housedust, alternaria, cat fur,
                   dog fur, ragweed, oak, rye grass, and Bermuda grass).The
                   tests were made on examined persons between the ages of 6
                   and 74 years, to obtain degrees of skin reaction.
             D.  X-Rays
                 For examined persons ages 25-74 years, two x-rays were made.
                 No x-rays were taken of pregnant women and no lumbar x-rays
                 were taken on women under 50 years of age.
               1.  X-ray of cervical and lumbar spine, were taken to provide
                   evidence of osteoarthritis and degenerative disc disease,
                   and
               2.  X-ray of chest, to be used in the diagnosis of respiratory
                   diseases and to serve as a measure of left ventricular
                   enlargement.
            E.  Urine tests
               Tests as follows were performed on casual samples of urine:
               1.  N-Multistix tests for qualitative protein, glucose,
                   ketones, bilirubin, blood, urobilinogen, pH, and
                   bacteriuria (nitrite test) were done for examined persons
                   ages 6-74 years.
               2.  Urinary sediments, including red cells, white cells, and
                   casts, were measured for a subsample of examined adults
                   ages 20-74 years.
               3.  Gonorrhea cultures, of urinary sediments were performed
                   for male and female examined persons ages 12-40 years.
                   However, of those females who received the Glucose
                   Tolerance Test (GTT) only those ages 20-24 years had the
                   gonorrhea test performed.
               4.  Analyses for pesticide residue and metabolite levels,were
                   carried out on a subsample of examined persons ages 12-74
                   years, including measures of the body burdens from
                   exposure to alkyl phosphate residues and metabolites,
                   carbamate residues, phenolic compound residues and
                   malathion metabolites.
           F.  Tests on blood samples
               Samples of blood provide a broad range of information related
               to health and nutrition.  The particular tests performed
               varied with the specific target condition and age group as
               described in the Series 1, No.15 program description (page
               39).
               1.  Glucose tolerance test (GTT)
                   This test involved collection of blood specimens while in
                 a fasting state, as well as at one and two hours after
                 glucose challenge.  The test was performed on a specified
                 subsample of examined adults to provide estimates of the
                 prevalence of diabetes.
               2.  Tests related to liver function
                   (a)  Post-prandial liver bile acid test.  This test
                    measures the ability of the liver to remove bile
                    acids from the blood following consumption of a food
                    preparation which induces eventual addition of bile
                          acids to the blood via contraction of the
                          gallbladder.
                  (b)  Liver biochemistries performed include bilirubin,
                       SGOT, and alkaline phosphatase tests.
                 3.  Anemia-related laboratory tests
                     The tests made to characterize anemia consisted of
                     protoporphyrin,iron,total iron binding capacity (TIBC),
                     zinc, copper, red cell folates, serum folates, serum
                     ferritin, B12, and the determination of abnormal
                     hemoglobin.
                 4.  Other nutritional biochemistries
                     These tests include albumin,Vitamin A and Vitamin C.
                 5.  Serum lipids
                     Because of their important relevance to cardiovascular
                     disease, determinations were made of cholesterol,
                     triglycerides, and high density lipoprotein (HDL).
                 6.  Biochemistries for body burden from environmental
                     exposures
                     Determinations were made of body burden levels of lead
                     and pesticide residues and metabolites.Tests were also
                     performed for carboxyhemoglobin which reflects
                     environmental exposure to carbon monoxide and the
                     individual's smoking habits.
                 7.  Hematology
                     The hematology included determinations of hemoglobin,
                     hematocrit,red blood cell count,white blood cell count
                     and differential leukocyte analysis, and red blood cell
                     morphology and hemoglobin phenotyping.
                 8.  Kidney function
                   The only quantitative test for kidney function performed
                   on blood samples was the serum creatinine test.
               9.  Syphilis
                   The serology determinations for syphilis included
                   qualitative and quantitative ART, a FTA-ABS and MHA-TP.
USE OF NHANES DATA

 NCHS requests the cooperation of recipients of data tapes in certain actions
 related to their use:

    1.  Any publication based on the data should acknowledge the National
        Center for Health Statistics (NCHS) as the original source.It should
        include a disclaimer which credits the authors for any analyses,
        interpretations, or conclusions, and not NCHS, which is responsible
        only for the data.

    2.  Consumers who wish to publish a technical description of the data
        should make a reasonable effort to ensure that the description is not
        inconsistent with that published by NCHS.This does not mean, however,
        that NCHS will review such descriptions.

    3.  The National Center for Health Statistics would appreciate receiving
        reprints of journal articles or other publications based upon find-
        ings from the NHANES II survey.  Please forward copies to:

              Division of Health Examination Statistics
              National Center for Health Statistics
              Center Building, Room 2-58,
              3700 East-West Highway
              Hyattsville, Maryland   20782
EDITING OF THE DATA SETS

 The data users' tapes have been subjected to a great deal of careful editing.
 Some of the continuous data items have extremely high or low values and it
 has been verified that they do in fact appear that way on the original inter-
 view documents; that is, it has been verified that the values have not been
 incorrectly keyed.Within each data tape numerous consistency checks have been
 performed.  However, due to the large volume of data collected in the survey,
 it is likely that a small number of errors or discrepancies remain undetected.
 The Division of Health Examination Statistics, NCHS would appreciate if any
 such errors are detected that they be brought to our attention so that errata
 sheets can be issued to previous purchasers and corrections made if new data
 tapes are created.
USE OF SAMPLE WEIGHTS

 NHANES II uses a multistage sample designed to represent the civilian
 noninstitutionalized population of the United States,6 months-74 years of age.
 Since the sample is not a simple random one, it is necessary to incorporate
 the person's sample weight for proper analysis of the data.The sample weight
 is a composite of the individual selection probability, adjustments for
 nonresponese, and poststratification adjustments.

 NHANES II provides information on 20,322 interviewed and examined individuals.
 In addition to the general examination components, several more detailed
 examinations were performed on subsamples of the population.  Therefore,
 instead of there being one sample weight per person,there are several sample
 weights for each person.  If a person was not selected for a particular
 subsample, their associated subsample weight is zero.  When analyzing the
 special subsamples, the analyst must be careful to select the appropriate
 sampling weight from the weights found in tape locations 282-317. For a more
 complete description of how the sample weights are calculated, see the
 detailed note section of this documentation.
SAMPLE DESIGN, VARIANCE ESTIMATION, AND HYPOTHESIS TESTING

 The data collected in the Second National Health and Nutrition Examination
 Survey (NHANES II) were obtained through a complex sample design involving
 both clustering and stratification.Because of the complex design and the
 ratio adjustments applied to the sample weights (see previous section on use
 of sample weights), the direct application of standard statistical analysis
 methods for variance estimation and hypothesis testing may be very misleading.
 The modification of statistical analysis procedures to incorporate the
 effects of complex survey designs is an important area of research;however,
 the current methodologies appropriate for the analysis of data from such
 surveys have not been made readily available in the standard packaged
 statistical software.

 There are computer programs available which do provide the capability of
 variance estimation for complex sample designs.  The balanced repeated
 replication approach 1/ is utilized in &REPERR-&PSALMS-OSIRIS.IV 2/ to
 calculate the variance-covariance matrix.SESUDAAN, SURREGR 3/ and SUPERCARP
 4/ are programs that calculate the variance-covariance matrix using the
 linearization approach 5/ (Taylor series expansion).

 In order to provide the user with the capability of estimating the complex
 sample variances in the NHANES II data using the above procedures, we have
 provided Strata and Pseudo Primary Sampling Unit (PSU) codes on all data
 tapes in positions 324-326. These variables and the sample weights are
 necessary for the calculation of variances.

 Even though the overall number of examined persons in this survey is quite
 large for statistical inference purposes, subclass analyses can lead to
 estimaters that are unstable, particularly estimates of variances.
 Consequently, analyses of subclasses require that the user pay particular
 attention to the coefficient of variation for the estimates of means,
 proportions and totals.In addition, small sample sizes, or a small number
 of PSU's used in the variance calculations may produce unstable estimates
 of the variances using the above computer programs.

 An NCHS Series 2 publication discussing these issues is in publication.6/

GENERAL NOTES, DEMOGRAPHIC INFORMATION, NHANES II

 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
 NHANES II probability sample.  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 in each
 household 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.

DETAILED NOTES, DEMOGRAPHIC DATA

 Size of Place

 Size of place classification was derived from the 1970 census. According to
 the definition used in the 1970 census, the urban population was comprised of
 all persons living in (a) places of 2,500 inhabitants or more incorporated as
 cities, boroughs (except Alaska),villages and towns (except towns in New York
 ,New England States,and Wisconsin),but excluding those persons living in the
 rural portions of extended cities; (b) unincorporated places of 2,500
 inhabitants or more; and (c) other territories included in urbanized areas.
 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.

 SMSA

 Except in New England,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 1970
 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. In New England, SMSA's consist of
 towns and cities, rather than counties.

 Family Unit Code

 All related sample persons in the same family unit have the same computer
 generated family unit code.  This will enable analysis of individual family
 units.

 Race

 The race of the respondent was marked by observation and the interviewers
 were instructed to assume the race of all related persons was the same as the
 respondent unless otherwise learned.The race categories were "White","Black"
 or "Other".  If the appropriate category could not be marked by observation,
 then race was asked.  Interviewers were instructed to record persons who
 responded with something other than White or Black,such as Japanese,Chinese,
 American Indian, Korean, Hindu, Eskimo, etc., as "Other"; and to include
 Mexicans,Puert Ricans and other persons of Latin American descent in "White",
 unless definitely Black, American Indian, or of other non-white race.

 Industry and Occupation Codes

 A person's occupation may be defined as his principal job or business. 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
 spent 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 Occupa-
 tion was used in the coding of both the industry and occupation. Library of
 Congress Number 74-612012.  For sale by the Superintendent of Documents,U.S.

 Family Income Group

 The respondent was handed a card with 12 income ranges listed as Group A to
 Group L and asked "Which of these income groups represents your total com-
 bined family income for the past 12 months,that is,yours, your ...'s, etc?
 include income from all sources such as wages,salaries,social security or
 retirement benefits, help from relatives, rent from property and so forth."

 If the respondent answered Group A through G,that is with an income less than
 $7,000,then questions 21 and 22 detailing exact sources and amounts of income
 were asked; otherwise, these questions were skipped.

 No effort was made to reconcile amounts reported in detailed questions 21 and
 22 with the categorical response to the family income group question.  During
 the survey time period, no adjustments to the income groups or $7,000 value
 were made to account for inflation.
 
 Land

 Land used for farming purposes (Code 1 in Tape Position 207) was identified
 as being rural land (Code 2 in Tape Position 25) consisting of 10 or more
 acres (Code 1 in Tape Position 26) with crop sales amounting to $50 or more
 (Code 1 in Tape Position 27), or rural land (Code 2 in Tape Position 25)
 consisting of less than 10 acres(Code 2 in Tape Position 26)with crop sales
 amounting to $250 or more (Code 1 in Tape Position 28).All other land is
 classified as nonfarm (Code 2 in Tape Position 207).

 Region

 The United States was divided into four broad geographic regions of
 approximately equal population. Those regions, which deviate somewhat from
 the groups used by the Bureau of Census, are as follows:

     Region                            States Included

 Poverty Index

 Income status was determined by the Poverty Income Ratio (PIR).  Poverty
 statistics published in the Census Bureau reports 1-5 were based on the
 poverty index developed by the Social Security Administration (SSA) in 1964.
 (For a detailed discussion of the SSA poverty standards, see reference 6.)
 Modifications in the definition of poverty were adopted in 1969.7 The stand-
 ard data series in poverty for statistical use by all executive departments
 and establishments has been established.8

 The two components of the PIR are the total income of the household (numera-
 tors the median of the income group for incomes $7,000 and above; the sum of
 the porponent parts of the income questions for incomes under $7,000) 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 tables, 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
 twice 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 variations in the
 cost of living (except for the farm, nonfarm difference).None of the noncash
 public welfare benefits such as food stamp bonuses are included in the income
 of the low income families receiving these benefits.PIR has been adjusted by
 year (see tables) and accounts in some part for inflation.

DETAILED NOTES

 Tape Positions 282-323

 A multistage estimation procedure was used to calculate the various NHANES
 II subsample sample weights that are necessary to use in any analysis of the
 data.The procedure has three basic components:(1) inflation by reciprocals
 of the probabilities of selection, (2) adjustment for nonresponse, and (3)
 poststratification ratio adjustment by age-sex-race. A brief description
 of each component is as follows:

     Inflation by reciprocals of the sampling probabilities.Since the survey
     utilized a three-stage sample design, there were three probabilities of
     selection:  (1) the probability of selecting the PSU,(2) the probability
     of selecting a segment (housing unit),and (3) the probability of select-
     ing a sample person.

     Adjustment for nonresponse.  Estimates from the NHANES II data were
     adjusted to account for sample persons who were not examined.  The
     estimates were inflated by a multiplication factor calculated within five
     selected income groups, three age groups, four regions, and standard
     metropolitan statistical area (SMSA) or non-SMSA.  The numerator of these
     factors was the sum of the weights for sample persons resulting from the
     reciprocal of the probability of selection, and the denominator was the
     sum of the weights for examined persons also resulting from the
     reciprocals of  the sampling probabilities.

 Poststratification by age-sex-race.  The estimates were ratio adjusted within
 each of 76 age-sex-race cells to an independent estimate,provided by the U.S.
 Bureau of the Census, of the population of each cell as of March 1, 1978,
 (approximate mid-point of the survey).  The ratio adjustment was a
 multiplication factor of which the numerator was the U.S.population and the
 denominator was the sum of the weights adjusted for nonresponse for examined
 persons.  This ratio estimation process makes the sample more closely
 representative of the civilian, noninstitutionalized population of the U.S.

 Potential bias of nonresponse.Usually a sizeable number of sample persons who
 initially are willing to complete the household information and some of the
 medical history questionnaire subsequently will not participate in the
 examination.This creates the potential for bias if these persons differ from
 other sample persons with respect to the variables being studied. Intense
 efforts were undertaken during NHANES II to develop and implement standard
 procedures and inducements that would reduce the number of nonrespondents
 and thereby reduce the potential for bias.

 The user needs to be aware of and should explore the potential bias for
 nonresponse in any analysis of the NHANES II data.


DIETARY INFORMATION

 As in NHANES I, dietary data were collected using 24-hour recall, 3-month
 food frequency and dietary supplement forms.  Formats of these dietary
 questionnaires are found in the NHANES II plan and operation publication
 included with this documentation.  The dietary data are available on four
 tapes:  (1) the MODEL GRAM TAPE, (2) the NUTRIENT COMPOSITION TAPE, (3) the
 24-HOUR RECALL--SPECIFIC FOOD ITEM TAPE and (4) the TOTAL NUTRIENT
 INTAKE/FOOD FREQUENCY/AND OTHER RELATED DIETARY DATA TAPE.

 Tapes (1) and (2) are the NHANES II dietary data bank, catalog Nos.5702/5703
 and are available from NTIS (order number PB81232878) at a cost of $185.00.
 They are used in the computer editing and processing of the NHANES II
 24-hour recall forms.  The public user of these tapes is responsible for the
 development of all software for any similar utilization of these tapes.
 Unlike the NHANES I Model Gram/Nutrient Composition Tapes, catalog nos.
 4702/4703, the dietary data bank used in NHANES II consists of only the
 food reported on the 24-hour recall forms collected during the survey.  An
 expanded data base was available to the dietary interviewers for coding
 purposes during the collection of the data.

 TAPE (1):  MODEL GRAM

       Tape (1) is the first part of a two-part nutrient data bank.  The
       first 199 records on this tape are the acceptable FOOD MODELS or
       combinations of food models used to aid the respondent in recalling
       amount of foods reported on the 24-hour recall form.  The second part
       of this tape consists of 2605 foods in numeric order with designated
       food group number, food code number, preferred model code, appropriate
       gram conversion factor, and alphameric description.  When listed by
       food group, the MODEL GRAM tape provided the basis for the coding
       manual used by dietary interviewers.  In some instances, more than one
       food was assigned the same food code, but only when the nutrient
       composition for each of the foods was extremely similar.

 TAPE (2):  NUTRIENT COMPOSITION

       Tape (2) provides a nutrient analysis of the 2605 foods found on the
       MODEL GRAM TAPE.  Calories and seventeen nutrients per 100 gram edible
       portion are provided for each food.  Nutrient values used to update
       foods on this tape reflect the nutrients available in the food between
       1976 and 1980.  These nutrient values were obtained either from the
       manufacturer, or from the U.S. Department of Agriculture's revised
       Handbook No. 8, sections 1-6 and data tape 456-3 (based on USDA
       Agriculture Handbook No. 456).

       For commercial foods that were reported ingested at least twenty
       times, the nutrient values reflect the most appropriate information
       (1980) available from the manufacturer.  If the food company did not
       provide the needed information, nutrient values from other sources
       were used, where possible.  Foods reported fewer than twenty times
       were not updated and may not reflect the most current nutrient
       analysis from the manufacturer.

       Detailed documentation of the NHANES II nutrient data bank update is
       available upon request from the Nutrition Statistics Branch, Division
       Health Examination Statistics, NCHS.

 Tapes (3) and (4) contain the dietary data as collected on the forms, or
 calculated as a result of processing the data using the nutrient data bank.

 TAPE (3):  24-HOUR RECALL--SPECIFIC FOOD ITEM DATA

       Tape (3) contains information on specific food items consumed by (a)
       ingestion period, (i.e., breakfast, lunch, dinner, and between-meal
       foods); (b) the times of day to the closest half hour the food was
       consumed; (c) the source of intake (i.e., home, school, restaurant);
       and calories and 17 nutrients for each food item contributing to the
       day's total intake.  Information is collected for the period of time
       midnight to midnight preceding the interview and generally reflects
       intakes reported on Mondays through Fridays, excluding most holidays.
       This is a result of the general scheduling of examinations on Tuesdays
       through Saturdays.

 TAPE (4):TOTAL NUTRIENT INTAKE/FOOD FREQUENCY/AND OTHER RELATED DIETARY DATA

       The TOTAL NUTRIENT INTAKE section of tape 4 consists of a summation of
       the food-specific nutrient information contained on TAPE (3) for
       calories and 17 nutrients for each respondent.

       The FOOD FREQUENCY section of tape 4 consists of reported frequencies
       of consumption of foods from 18 food groups, of which 5 have
       subdivisions for a total of 26 separate categories.  Data are intended
       to reflect usual eating habits of the respondent over the 3 month
       interval prior to the dietary interview and do not include irregular
       eating habits associated with illness or dieting.  Data reflect
       information on foods consumed daily or weekly, Monday through Sunday,
       and holidays.  This food frequency questionnaire served as a crude
       quality control instrument for the 24 hour recall in addition to
       providing profiles of eating habits.

       OTHER RELATED DIETARY DATA on tape 4 includes information related to
       food consumption habits recorded on the 24-hour recall and dietary
       supplement forms, such as vitamin-mineral usage and special diets.

SPECIAL NOTE

 Since there is a separate data record for each food item consumed by each
 examined sample person, the total number of records found on the microdata
 tape is 347,925.  However, there are only 20,322 examined persons, with one
 or more data records (one for each food item consumed).  The demographic
 information is located in tape positions 1-350 on every data record.
 However, the tape description for this data shows only the counts for the
 total number of examined persons rather than the total number of data
 records.

USE OF SPECIAL TERMS, DIETARY DATA

 24-Hour Recall--Specific Food Item Data

 The term "data user work area" refers to blank areas in the data tape which
 are reserved for the user as needed.

 The term "blank, but applicable", is used to indicate a data item that was
 to have a response for a sample person but none was given.  The terms
 "blank" and "Not applicable" refer to data items where the sample person
 was not supposed to respond to the question or receive the examination
 component.

 To more fully understand the questionnaire skip patterns and the
 categorizations used, see the Plan and Operation of the Second National
 Health and Nutrition Examination Survey document included with this
 documentation.  All the questionnaires are included in this document.

DETAILED NOTES, DIETARY DATA
 
 In NHANES II, 230 sample persons had unsatisfactory 24-hour recalls.  For
 each of these persons, a satisfactory 24-hour recall for a person from a
 of these persons, a satisfactory 24-hour recall for a person from a similar
 age-sex-race category was substituted so that the data tape is complete for
 all data items related to the recall.  Each data record that was created in
 this manner has a code of "1" in column 366 of the data tape.  This resulted
 in 3,829 food items of imputed 24-hour recall data for these 230 persons.
