 DESCRIPTION OF SURVEY

 Description of Survey:  A detailed description of the design, content and
 operation of HANES I is provided in the following reports:  Plan and
 Operation of the Health and Nutrition Examination Survey, DHEW Pub. 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 specifica-
 tions 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.*

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.

 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 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.

 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.

 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.

GENERAL NOTES, ANTHROPOMETRY DATA, HANES I

 Anthropometry, Goniometry, Skeletal Age, Bone Density and Cortical
 Thickness Examinations:  In the mobile examination center, two health
 technicians obtained measurements of height and weight and a series of
 body and skinfold measurements for all examinees.In addition, x-rays of
 the hand and wrist were taken of examinees 1-17 years of age.  Goniometry
 data was collected for detailed examinees aged 25-74 years only at
 locations 1-35.

 Anthropometry Data Editing: All anthropometric measurements obtained in
 the mobile examination center were compiled and keyed by the U. S. Bureau
 of the Census and sent to the Division of Health Examination Statistics on
 tape. The data was edited for completeness and accuracy and certain
 consistency and range edits were performed to check for unusual or
 problematic data. When a question of accuracy arose,reference was made to
 microfilm records of the original recording documents.

DETAILED NOTES, ANTHROPOMETRY DATA

 Tape Pos. 214-216,221-223,228-230,235-237,274 - Left Side Meas.

 Left side measurements of the tricepts skinfold, subscapular skinfold, elbow
 breadth, and upper arm girth were randomly done on approximately 20 percent
 of the examined sample persons.Handedness was also recorded for these sample
 persons who had both right and left side measurements. These measures were
 collected for quality control purposes and are not a representative sample
 of the U. S. population.Therefore, none of the sample weights are applicable
 for analyses using these measurements.

 Tape Positions 242-245 - Sitting Height

 Sitting height was measured on all sample persons aged two years or more.
 Because of many procedural problems, many of the two year old children
 were not measured for sitting height.Since the number of missing values
 for this age was so large, no attempt was made to impute values for the
 missing measurements, as was done for ages three years and over. The
 sitting heights for two year old children that were recorded are included
 on the data tape but do not represent a national probability estimate for
 this age.

 Tape Positions 331-332, 344-345 - Extension of the Knee

 The extension of the knee is normally an observed measure of zero degrees.
 The examinee lied on his back with the back of his knee flat on a
 table.The small number of abnormal measurements (unable to extend a zero
 degree angle) is somewhat unusual for both the right and left extensions;
 nevertheless,the data have been verified and are in fact the actual
 measurements.

 Tape Positions 339-340, 352-353 - Adduction of the Hip

 The adduction of the hip is normally an observed measure of zero degrees.
 It seems somewhat unusual that the data shows an incredibly small number
 of examinees who are unable to adduct their hips to zero
 degrees.Nevertheless, all data values have been verified and are in fact
 actual measurements.

 Tape Position 502 - Individual Differences

  Individual differences
  Codes one(1) and two (2) in tape position 502 indicate any developmental
  or pathological abnormalities on one or more of the hand-wrist bones
  identified by the x-ray assessors.  Code three (3) indicates film quality
  or readability.

 Tape Positions 516-517 - Number of Fields with Bone Age Entry

 Number of fields with bone age entry
 After excluding eights (8),blanks and nines (9) from the high order
 positions 409, 412, 415, 418, 421, 424, 427, 430, 433, 436, 439, 442,
 445,448,451, 454, 457, 460, 463, 466, 469, 472, 475, 478, 481, 484, 487,
 490, 493,496, and 499 -count the number of remaining fields with usable
 bone-age entries in columns 409-501 (Maximum = 31).

 Tape Positions 518-521 - Sum of Bone-Age Entries

  Sum of bone-age entries
  Exclusions as for columns 516-517.  Then add the bone age entries in
  these three digit fields.

 Tape Positions 522-526 - Average Bone Age

 Average bone age
 Average bone age is determined by dividing columns 518-521 by columns 516-
 517. Exclusions are the same as for columns 516-517.

 Tape Positions 537-538 - Number of Adult Bones Per Youth

 Number of adult bones per youth
 The total number of adult bones per youth is determined by excluding 0-8
 and blanks in the high order positions 409, 412, 415, 418, 421, 424, 427,
 430, 433,436, 439, 442, 445, 448, 451, 454, 457, 460, 463, 466, 469, 472,
 475, 478, 481, 484, 487, 490, 493, 496, and 499 - then count the number of
 fields with code 9 in the remainder of these high order positions (Maximum
 = 31).

 Tape Positions 539-540 - Number of Uniformed Bones Per Youth

 Number of unformed bones per youth
 The number of unformed bones per youth is determined by adding the entries
 in columns 516-517 and columns 537-538 and subtracting this sum from
 31.The maximum should be less than 30.

 Tape Positions 541-543 - Bone Age Range

  Bone age range
  Excluding blanks, eights (8) and nines (9), the range for bone age is the
  maximum (largest) bone age entry in 3-digit field 409-501 minus minimum
  (smallest) bone age.
