INTRODUCTION

     The National Center for Health Statistics (NCHS) is the primary source
 of vital and health statistics for the United States. Data from NCHS are
 made available to the public in a number of individual reports and
 publication series, special tabulations, data releases, and through
 electronic media including data diskettes and an extensive set of public-use
 data files. This catalog lists and describes the public-use data files
 produced by NCHS.  More than 500 public-use data files, representing most of
 the NCHS data collection programs, are available for purchase and use.
 Public use data public files are prepared and disseminated to speed and
 enhance access to the full scope of data. NCHS data systems include a
 national vital registration program; household interview and health
 examination surveys; surveys of hospitals, nursing homes, physicians, and
 other health care providers; and other periodic or occasional data
 collection activities to produce a wide spectrum of health and health-
 related data. NCHS data users encompass all levels of government, the
 academic and research communities, and business.  The majority of the data
 files released by NCHS contain microdata to allow researchers to aggregate
 findings in whatever format appropriate for their analyses.

How to use this catalog
    The catalog is organized by NCHS data system or survey. Information is
 presented on the content of each file, source of the data, technical
 characteristics of the file, documentation, ordering instructions, and other
 information to aid the user in identifying and acquiring NCHS data tapes.

NCHS data release policy
    NCHS policy states that the statistical data it gathers be disseminated
 to all interested consumers as promptly as resources permit. NCHS releases
 public-use data files for elementary units (persons, events, or health
 facilities, and services) in a manner that will not in any way compromise
 the confidentiality guaranteed the respondents who supplied the original
 data. The measures taken to protect confidential information include the
 following:

  -Personal names and addresses, except for those on some nonconfidential
   institutional records, never appear on the data tapes.

  -Certificate numbers of vital records never appear on the tape records.

  -Data from localities having less than 100,000 population are classified
   into geographic areas that reflect population size but do not reveal
   specific geographic names.

  -Rare characteristics that might help to identify an individual or
    establishment are omitted.

    In addition, all purchasers of NCHS data files are required to sign a
 data use and purchase agreement (included on the NTIS order form) to assure
 that the NCHS public-use data files will be used solely for statistical
 research or reporting purposes.

Guidelines on use
    The National Center for Health Statistics requests that recipients of
 data files cooperate in certain actions related to their use. Any published
 material derived from the data should acknowledge the Center as the source.
 It should also include a disclaimer that credits any analyses,
 interpretations, or conclusions reached by the author (recipient of the
 file) and not to the Center, which is responsible only for the initial data.
 Users who wish to publish a technical description of the data should make a
 reasonable effort to ensure that the description is consistent with that
 published by the Center.
     Guidance on how to approximate the sampling variances of the estimates
 compiled by the Center and information about the magnitude of the
 nonsampling errors are provided with the documentation that accompanies the
 tapes or diskettes. Users are urged to include appropriate sampling error
 statements in all data they publish. Information is also available on
 biases, and users should include statements on the biases known to affect
 the data in any reports they may publish.

Ordering information

General Information
    Each public-use data tape in this catalog has a fixed-content fixed-
 format and comes with a complete documentation package. The data are in
 9-track code, either extended binary coded decimal interchange code (EBCDIC)
 alone or in combination with binary code. Tapes are available at 1600 or
 6250 bytes per inch (bpi) as specified by the requestor. NCHS does not
 convert the data tapes to any other code formats. Record lengths, block
 sizes, number of records, and number of reels are provided in the detailed
 descriptions in the catalog.
     For microcomputer users, NCHS data files are also available from NTIS on
 diskette in ASCII or formatted in one of the major data base programs. Data
 from the National Hospital Discharge Survey, National Medical Care
 Utilization Expenditure Survey, and National Survey of Personal Health
 Practices and Consequences are available on diskettes. NTIS can provide the
 full file, or a subset, on disc for other NCHS data files and will process
 the order on an individual basis. Check with NTIS for a price quote and to

Data Purchase and Use Agreement

    The Public Health Service Act (42 U.S.C. 242m(d) provides that the data
 collected by the National Center for Health Statistics (NCHS) may be used
 only for the purpose for which they were obtained; any effort to determine
 the identity of any reported cases, or to use the information for any purpose
 other than for health statistical reporting and analysis, would be against
 the law.  NCHS does all it can to assure that the identity of data subjects
 cannot be disclosed through public-use data sets; all direct identifiers, as
 well as any characteristics that might lead to identification, are omitted
 from the data set.  Nevertheless, it may be possible in rare instances,
 through complex analysis and with outside information on sample cases, to
 ascertain from the data set the identity of particular persons or
 establishments.  Considerable harm could ensure if this were done.
 Therefore, the undersigned gives the following assurances with respect to all
 NCHS public-use data sets:
  -No one will use the data in these sets inn any way except for statistical
   reporting and analysis;
  -No one will release the data sets or any part of them to any person who is
   not a member of this organization, except with the approval of NCHS;
  -No person having access to the data sets will attempt to use them to learn
   the identity of any person or establishment included in any set; and
  -If the identity of any person or establishment should be discovered
   inadvertently, then (a) no use will be made of this knowledge, (b) the
   Director of NCHS will be advised of the incident, (c) the information that
   would identify an individual or establishment will be safe-guarded or
   destroyed, as requested by NCHS, and (d) no one else will be informed of
   the discovered identity.

     The Public Health Network (PHN), a subsidiary function of the Public
 Health Foundation, is an on-line computer network that provides electronic
 mail and other services for national and international communications. NCHS
 provides inputs to the PHN through the Centers for Disease Control. Data
 available from the NCHS include the latest issue of the Monthly Vital
 Statistics Report (MVSR), news releases, and descriptions of recently
 released publications and electronic data products.
     The MVSR provides provisional statistics on births, marriages, divorces,
 and deaths. Tables include rates and numbers for live births, deaths and
 infant deaths, natural increase, marriages and divorces for the reported
 month and the same month a year ago, with cumulative totals for each of the
 last 3 years.
    A segment of the PHN lists recent NCHS publications and electronic data
 products. Titles, brief descriptions, and ordering information are provided.
    Important new data releases from NCHS are announced to the media through
 new releases from the Department of Health and Human Services and through

NATIONAL HEALTH INTERVIEW SURVEY

General survey description
    The National Health Interview Survey is a continuing nationwide survey of
 the U.S. civilian noninstitutionalized population conducted in households.
 Each week a probability sample of households is interviewed by trained
 personnel of the U.S. Bureau of the Census to obtain information about the
 health and other characteristics of each living member of the sample
 household. During a year the sample is composed of 36,000 to 47,000 households
 including 92,000 to 125,000 persons, depending on the year.
    Information is obtained on the number of restricted-activity days, bed
 days, work- or school-loss days, and all physician visits occurring during
 the 2-weekperiod prior to the week of the interview. Data are also obtained
 on the acute and chronic conditions that were responsible for these days or
 visits.  Respondents are asked about long-term limitation of activity and
 the chronic conditions related to this disability. All conditions are coded
 according to the International Classification of Diseases, using the limited
 diagnostic detail available from a household respondent. Data are obtained
 on all hospital episodes during the prior 12 months, including length of
 stay and whether or not surgery was performed.

Data tape description
    For each sample person there are five possible record types, each
 containing data on a particular topic:  health conditions, doctor visits,
 hospital stays, household characteristics, and person characteristics.
    Selected items from the person and household records also ar included on
 each of the other record types. The records are arranged in five files, one
 for each record type. Data items contained in each record type are shown in
 table 1.

Geographic coverage
    Each person's region of residence (four Census categories) is shown. If
 the sample person lived in one of the larger SMSA's that was selected into
 the sample with certainty, the SMSA is identified for data years 1969-84.

Time coverage
    Data tapes are available for each year from 1969 through 1988.

Technical characteristics
    Files are given in a fixed block format, and all files for a given year
 have the same record length and block size. Record length, block size, and
 number of records are shown by year in table 2.
Documentation contents
    Each data tape package includes all necessary documentation, including
 tape content, Interviewer's Manual, medical coding instructions, sample
 tabulation specifications, and related final data tables from publications.

Related reports
    A more detailed description of the survey and summary tables of 1969-88
 data can be found in the "Current Estimates" reports, Series 10, Numbers 63,
 72, 79, 85, 95, 100, 115, 119, 126, 130, 136, 139, 141, 150, 154, 156, 160,
 164, 166, and 173.
    In addition to the data tapes already described, which are available
 through the National Technical Information Service, tapes containing data
 collected in special supplements to NHIS are available directly from NCHS. A
 list of the supplements or current health topics and prices is shown in
 table 3.

 A sample of 5,151 people in the Supplement on Aging (SOA) aged 70 years and
 over in 1984 was selected for reinterview in 1986. The 1986 Reinterview was
 designed to measure change in functional status and living arrangements,
 and to characterize the transition from functionally independent living in
 the community through dependence and possible institutionalization, to
 death. This is the first of a number of data tapes that will provide
 findings from the LSOA. All 16,148 people in the SOA will be followed for
 6 years through matches with NCHS's National Death Index. All 11,497 people
 in the SOA, age 65 and over in 1984, will be followed for 6 years through
 matches with the Medicare Part A records. Selected samples of people in the
 SOA will be followed through additional reinterviews.

NATIONAL HEALTH AND NUTRITION EXAMINATION SURVEY

General Survey Description
    Since 1959, NCHS has conducted the National Health Examination Survey
 (NHES) to obtain statistics on: (1) the medically defined prevalence of a
 variety of diseases in the United States and (2) distributions of certain
 physical, physiological, and psychological measurements in the general
 population. The NHES was conducted as a series of survey programs called
 "cycles."  Each cycle was limited to a specific age segment of the
 population and to certain aspects of the health of the population.
    In 1970, NCHS received a new responsibility--measuring and monitoring the
 nutritional status of the U.S. population over time. NHES was expanded and
 redesigned to include this type of assessment along with the health
 assessments already part of its mission, thus becoming the National Health
 and Nutrition Examination Survey (NHANES).
    Both NHES and NHANES I were operated in a similar manner. Examinations
 were conducted in mobile examination centers at numerous sample locations
 across the United States by a specially trained staff of medical personnel
 and interviewers.  During the entire course of NHANES I, for example,
 examinations were conducted at 100 locations.
    The first NHANES program (NHANES I) was conducted from 1971075 on a
 sample of the U.S. population aged 1074 years. (Unlike the previous NHES
 cycles, NHANES includes a very wide age range in each program.) Four
 different kinds of data were collected to make this nutritional assessment:
 (1) dietary intake information, (2) hematological and biochemical tests,
 (3) body measurements, and (4) clinical assessments. Some limited
 information on general health status, health care needs, and treatment was
 also obtained. The information included examination findings and medical
 history on eye conditions, skin conditions, and dental health. Further data
 on health status and medical care needs were obtained through more detailed
 examinations and history for a subsample of adults aged 25-74 years.
 Particular consideration was given to cardiovascular, respiratory, arthritic,
 and auditory conditions.
    In NHANES II, examinations were conducted from February 1976 through
 February 1980. Because much of the content of NHANES II was planned to be
 identical to that of NHANES I, data from this later survey provide the first
 look at change in the health and nutrition status of the population over
 time. Additional tests and procedures were also included to provide data on
 diabetes, kidney disease, heart disease, hypertension, certain allergies,
 disk degeneration, pulmonary function, and hearing and speech problems.
    In Hispanic HANES, examinations were conducted from July 1982 through
 December 1984. Hispanics were included in past health and nutrition
 examinations, but not in sufficient numbers to produce estimates of the
 health of Hispanics in general nor specific data for Puerto Ricans, Mexican-
 Americans, or Cuban-Americans. All examinees had a medical history, dental
 exam, body measurements, a dietary interview, and numerous laboratory tests
 on blood and urine specimens. Children six and over had vision and hearing
 tests. Most of the other specialized tests, such as gallbladder ultrasound,
 glucose tolerance, electrocardiogram, and liver disease tests, were given to
 a selection of those 20 years or older.
HISPANIC HEALTH AND NUTRITION EXAMINATION SURVEY, 1982-84

Specific survey description

General Information
    Hispanic HANES (HHANES) was conducted on a nationwide probability sample
 of approximately 16,000 persons, aged 6 months-74 years, in the
 noninstitutionalized population of eligible Hispanics: Mexican-Americans in
 the southwest; Puerto Ricans in the New York area (defined as selected
 counties in New York, New Jersey, and Connecticut); and Cuban-Americans in
 Dade County (Miami), Florida. Of this sample, 11,653 persons were examined:
 7,462 Mexican-Americans, 1,357 Cuban-Americans, and 2,834 Puerto Ricans.

Data collection techniques and content

Questionnaires administered in the household

Household screener questionnaire
    This questionnaire was used in each household to determine household
 composition and eligibility (that is, appropriate Hispanic ethnicity) and
 for the selection of sample persons.

Family questionnaire
    This form was administered to each eligible family and contained five
 sections: a) a family relationship chart which determined kinship for sample
 persons under 20 years old; b) a family characteristics section, which
 obtained for heads of families and all sample persons basic demographic
 information, such as race, education, place of birth, occupation, and marital
 status; c) a section on Medicare and health insurance coverage; d) questions
 on participation in income assistance programs; and c) selected housing
 characteristics, family income, and participation in food stamp programs.

Adult sample person questionnaire
    For sample persons 12-74 years of age, this questionnaire included items
 on health habits, tuberculosis, anemia, smoking, weight status, functional
 impairment, chronic conditions, pesticide exposure, acculturation, meal
 programs, and medicine and vitamin usage. To address the issues of health
 care needs and health status assessment, detailed sections on health
 services, dental care, diabetes, vision, hearing, hypertension, digestive
 disease, and cardiovascular conditions were included. Finally, to facilitate
 linkage with the National Death Index, full name, father's name, and social
 security number were obtained.

Questionnaires administered in the mobile examination center
 Dietary questionnaire
    For each sample person, a trained dietary interviewer recorded the
 quantity of every item of food or drink consumed during the previous day,
 thus enabling estimates to be made of calories, protein, carbohydrates, fat,
 unsaturated fats, cholesterol, and specific vitamins and minerals consumed
 during the recall period. A food frequency section ascertained usual patterns
 of food consumption measured by daily and/or weekly frequency of groupings,
 including milk, meat, fish, eggs, fats and oils, legumes and cereals, fruits,
 vegetables, and alcoholic beverages. Additional questions on special diets
 and dietary practices were included in this questionnaire.

Adult sample person supplement
    This questionnaire was administered to examined persons 12-74 years of
 age. It contained sections on recent periodic exposure, cigarette smoking
 for persons 12 through 19 years of age, reproductive history for females,
 alcohol consumption, drug abuse, and, for persons 20-74 years of age,
 depression.

Examination by physician
    A physician performed and recorded a medical examination giving special
 attention to specified findings related to hearing, vision, gallbladder
 disease, and the cardiovascular, neurological, and musculoskeletal systems.
 The physician also assessed overall health status, nutritional status, and
 weight status and noted diagnostic impressions and related health care needs.

Special clinical procedures and tests
 Ultrasound examination of the gallbladder
    For the purpose of estimating the prevalence of gallstones, an ultrasound
 examination was conducted on a specified subsample of examinees 20-74 years
 of age.

 Dental examination
    All examined persons received an examination that included the following
 measures of dental health: 1) a Decayed, Missing, Filled (DMF) surface index,
 2) a Dental Restorative Treatment Needs Index, 3) a simplified Oral Hygiene
 Index, 4) a Periodontal Index, 5) assessment of need for and quality of full
 dentures, and 6) assessment of malocclusion.

 Vision screening
    Examined persons 6-74 years of age were tested for visual acuity. The
 near vision and distance vision tests involved reading test cards with Sloan
 letters or Landolt rings set at standard distances from the eyes.
 Binocularity of vision was tested by using the Random Dot E (RDE) test.

 Tympanic impedance
    For the purpose of assessing levels of effusive and noneffusive middle
 ear disease, impedance tympanometry was performed on all examined persons. In
 this procedure, the mobility of the tympanic membrane is induced and recorded
 electronically under varied air pressures in the ear canal.

 Puretone audiometry
    This test, conducted on examined persons between the ages of 6 and 74,
 permitted determination of threshold levels of hearing for frequencies of
 500, 1,000, 2,000, and 4,000 hertz for each ear.

 Electrocardiograms
    Electrocardiographic signals, for examined persons 20-74 years of age,
 were digitized and recorded on magnetic tape, providing normative data on
 amplitude, duration, interval, and axis measurements, and permitting
 interpretations of heart disease according to the Minnesota classification
 code.

 Body measurements
    Measurements were made on all examinees and included standing height
 and/or recumbent length, depending on age; body weight; triceps and
 subscapular skinfolds; and various other measurements.

 Tuberculin skin test
    In the California and Dade County, Florida, PSUs, examinees were injected
 with 5 Tuberculin Units of purified protein derivative (PPD) to test for
 exposure to tuberculosis. Examinees were examined at the examination center
 or at home 2 or 3 days later by a trained nurse who read and recorded the
 test results.

 X-rays
    Two chest X-rays were made, as follows:

 -Posterior-Anterior (PA)
    This X-ray, done on persons 20-74 years of age, was used for the
    diagnosis of heart size and cardiovascular conditions, lung and chest
    conditions, and structural deformities.

 -Lateral
    Done on persons 45-74 years of age, this X-ray provided an additional
    parameter for the determination of heart size.
 *No X-rays were done on pregnant women.

 Urine tests
    The following tests were performed on casual samples of urine:

 N-Multistix tests
    The urinary dipstick tests for qualitative protein, glucose, ketones,
    bilirubin, blood, urobilinogen, pH, and bacteriuria (nitrite test) were
    done for examined persons 6-74 years of age.

 Urinary sediments
    Sediments including red cells, white cells, and casts were measured for
    persons 6-74 years of age.

 Analysis for pesticide levels
    Urine samples from a half-sample of examined persons 12-74 years of age
    were tested for the presence of alkyl phosphate residues and metabolites,
    carbamate residues, phenolic compound residues, and malathion metabolites.

 Tests on blood samples
    Tests on blood samples provide a broad range of information related to
    health and nutrition. The particular tests performed varied with the
    specific target condition and age group.

 Oral glucose tolerance test (OGTT)
    This test involved the collection of blood specimens from examined
    persons while in a fasting state as well as at 1 and 2 hours after glucose
    challenge. The test was performed on a specified half-sample of examined
    adults 20-74 years of age to provide estimates of the prevalence of
    diabetes and impaired glucose tolerance.

 Liver function tests
    Biochemical liver tests, performed on examined persons 20-74 years of age,
    included bilirubin, SGOT, SGPT, and alkaline phosphatase.

 Anemia-related laboratory tests
    For the diagnosis of anemia, tests on blood samples included
    protoporhyrin, iron, total iron-binding capacity, red cell folates, serum fo
    ferritin, and abnormal hematological indices.

 Other biochemical nutritional tests
    These tests included albumin and vitamin A.

 Serum lipids
    Because of their relevance to cardiovascular disease, determinations were
    made of serum cholesterol, triglycerides, and high-density lipoprotein
    (HDL).

 Biochemical tests for body burden from environmental exposures
    Levels of lead (all persons) and organochlorine pesticide residues and
    metabolites (half-sample of persons 12-74 years of age) were determined.
    Tests for carboxyhemoglobin and thiocyanate were performed on a half
    sample of persons 3-74 years of age for the first 12 examination sites
    only.

 Hematology
    The hematological determinations included hemoglobin, hematocrit, red
    blood cell count, white blood cell count and differential analysis, and
    red blood cell morphology.

 Kidney function
    The serum creatinine test for kidney function was performed on blood
    samples.

SECOND NATIONAL HEALTH AND NUTRITION EXAMINATION SURVEY, 1976-80
Specific survey description
    The second National Health and Nutrition Examination Survey, NHANES II,
 was conducted between 1976 and 1980 on a nationwide probability sample of
 27,801 persons from 6 months to 74 years of age selected from the civilian
 noninstitutionalized population of the United States. From this sample,
 25,286 people were interviewed and 20,322 persons were examined, resulting
 in an overall response rate of 73 percent. Because children and those persons
 classified as living at or below the poverty level were assumed to be at
 special risk of having nutritional problems, they were sampled at rates
 substantially higher than their proportions in the general population.
 Adjusted sampling weights were computed within 76 age-sex-income groups in
 order to inflate the sample to closely reflect the target population at the
 midpoint of the survey.
Data collection techniques and content
Summary statement of data collection techniques.
 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, neurologic 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 conditions,
         hearing and speech, liver and gallbladder condition, kidney and
         bladder disease, allergies, hypertension, cardiovascular
         condition, stroke, arthritis (stressing middle and upper back
         and neck problems), and participation in food programs.
     (3)Dietary Questionnaires were given by a trained dietitian.
        (a)For each examined person, a 24-Hour Recall was administered.
         Specific and quantitative detail of every item of 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 during the recall period.
        (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 a history of
         special diets, recent medications, and barriers to purchasing
         groceries or eating foods; it did not provide information on
         vitamin, mineral, or other supplements to the diet.
     (4)Medication and Vitamin Usage Form provided information on the past
      week's usage of any medicines; vitamins or mineral for all examined
      persons.
     (5)Behavior Questionnaire elicited data on behavior that 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,
    neurologic, 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 including 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, 1,000, 2,000 and
      4,000 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
      interpretation as an indication of problems with articulation and
      language development.
     (6)Allergy tests, involving skin tests (prick test) with eight common
      allergens (house dust, 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 was taken to provide evidence of
      osteoarthritis and degenerative disk disease.
     (2)X-ray of chest was taken to diagnose 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. Test 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.
     (1)Glucose tolerance test (GTT)
      This test involved collection of blood specimens while in a fasting
      state as well as at 1 and 2 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)Postprandial 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 l
     (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 determination s of hemoglobin, hematocrit
      red blood cell count, white blood cell count and differential
      analysis, and red blood cell morphology and hemoglobin phenotyping.
     (8)Kidney function
      The only 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, an FTA-ABS, and an MHA-TP.

FIRST NATIONAL HEALTH AND NUTRITION EXAMINATION SURVEY. 1971-75

Specific survey description
    NHANES I was conducted on a nationwide probability sample of approximately
 32,000 persons aged 1-74 years in the civilian noninstitutionalized
 population of the conterminous United States. The survey started in April
 1971; the nutrition component and some general health components were
 completed in June 1974. The NHANES 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 preset rates. On completion of the survey, 31,973 sample
 persons had been interviewed; of these, 23,808 people were examined. Adjusted
 sampling weights were computed within 60 age-sex-race categories in order to
 inflate the sample so as to closely reflect the U.S. civilian
 noninstitutionalized population 1-74 years of age at the midpoint of the
 survey.  Although a major emphasis of NHANES I was on nutrition and some
 limited aspects of health, a subset of 3,854 persons aged 25-74 received a
 more detailed health examination. No oversampling of subgroups of the
 population was done in this subsample, as it had been for the major
 nutrition component. This subsample is representative of the U.S. population
 25-74 years of age at the midpoint of NHANES I. After the nutrition survey
 was completed, the detailed medical examination was given to adults 25-74
 years of age. This portion of the survey is referred to as the NHANES I
 Augmentation and was continued through October 1975, bringing the total
 number of persons who received a detailed examination to 6,913.

Data collection techniques and content

General Information
    Information for all examined persons in NHANES I was obtained by means of
 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, dermatologic, and ophthalmologic
 examinations; anthropometric measurements; hand-wrist X-rays (for skeletal
 maturation assessments of those ages 1-17 only); and hematologic, blood
 chemistry, and urologic laboratory determinations.
    Additional data were gathered on the subsample of adults ages 25-74 by
 means of a supplementary medical history questionnaire; supplementary
 questionnaires concerning arthritis, respiratory conditions, and
 cardiovascular conditions (when applicable); a health care needs
 questionnaire; a general well-being questionnaire; an extended medical
 examination; X-rays of the chest for determination of heart size and
 pathology, as well as lung volume and pathology; X-rays of the
 hip-sacroiliac and knee joints for assessment of arthritic and related
 changes, X-rays of the hand and wrist for measurements of bone density and
 cortical thickness; audiometry, electrocardiography; goniometry; spirometry;
 pulmonary diffusion and tuberculin tests; and additional laboratory
 determinations.
    NHANES I was composed of two overlapping sets of examination components.
 The nutrition examination was given to all sample persons at the survey
 locations, and the detailed medical examination was given to a subsample of
 adults ages 25-74 years at the first 65 survey locations. This survey was
 continued as the NHANES I Augmentation for 35 additional locations after the
 nutrition examinations had ended.
    This resulted in six distinct NHANES I samples, each a separate
 probability sample and each with its own set of sampling weights. Note that
 although 23,808 persons were examined during the entire course of NHANES I,
 this is not a probability sample. This number represents the total nutrition
 sample of 20,740 (including the subsample of 3,854 of this group given the
 detailed examination also) and the detailed subsample of 3,059 adults who
 were examined in the augmentation portion of the survey.

NATIONAL HEALTH EXAMINATION SURVEY, CYCLE III, 1966-70

Specific survey description
      NHES III was conducted on a nationwide probability sample of 7,514
 youths 12-17 years of age in the civilian noninstitutionalized population of
 the conterminous United States.  The survey began in March 1966 and was
 completed in March 1970.  Of the 7,514 youths selected for the sample, 6,768
 (90 percent) were examined.  Adjusted sampling weights were computed in order
 to inflate the sample so as to closely reflect the 23 million youths in the
 U.S. population at that time in terms of age, sex, and certain other
 demographic characteristics.
     Because the same basic sampling plan was used in Cycle III as in the
 earlier Cycle II, nearly one-third of the children examined in Cycle II were
 also examined in Cycle III.  In the Cycle III Extended Data Tape (EDT),
 provision has been made for the user to identify sample persons examined in
 both surveys and to create from the Cycle II Integrated Data Tape (IDT) and
 the Cycle III EDT a composite data set for longitudinal studies.
Data collection techniques and content
      Information was obtained for each examined youth by means of a household
 interview; detailed questionnaires for medical and developmental histories; a
 school questionnaire; medical, dental, and psychological examinations; vision
 and hearing tests; anthropometric measurements; and certain x rays and
 laboratory tests.
Geographic coverage
 Civilian noninstitutionalized U.S. population between the ages of 12-17 yrs.
Time coverage
    All data tapes available from the third cycle of the National Health
 Examination Survey contain data collected over the entire course of the
 survey: March 1966 to March 1970.
Documentation contents
    The major data elements obtained and derived from this survey have been
 compiled into one EDT, which is available for release.  The data tape
 documentation contains a brief description of NHES, a file description, a
 detailed description of the data items, and detailed notes on items judged
 not to be self-explanatory.  A sample weight for each examined person is
 included.

NHANES I EPIDEMIOLOGIC FOLLOWUP STUDY
General survey description
    The NHANES I Epidemiologic Followup Study (NHEFS) is a longitudinal study
 which uses as its baseline those adult persons ages 25-74 years who were
 examined in the first National Health and Nutrition Examination Survey
 (NHANES I).  The study was jointly sponsored by the National Center for
 Health Statistics (NCHS), the National Institute on Aging, and other
 components of the National Institutes of Health and Public Health Service.
 The primary purpose of the followup study is to investigate the relationships
 between physiological, nutritional, behavioral, and demographic
 characteristics collected at the NHANES I interview (1971-75) and subsequent
 morbidity or mortality from specific diseases and conditions.
      The NHEFS is comprised of a series of followup surveys.  The first wave
 of data collection was conducted from 1982 to 1984 and included all persons
 who were between 25 and 74 years of age at their NHANES I examination
 (n = 14,407). Tracing was successfully completed on 93 percent of the cohort.
 Personal interviews including weight, pulse, and blood pressure measurements
 were conducted with traced, surviving subjects.  Interviews with proxy
 respondents were conducted for deceased or incapacitate subjects.  Hospitals
 and nursing home records were obtained for all subjects and death
 certificates were obtained for decedents.
      The second wave, 1986 NHEFS, was conducted for members of the NHEFS
 cohort who were 55-74 years of age at their baseline examination and not
 known to be deceased at the 1982-84 NHEFS (n = 3,980).  Computer-assisted
 telephone interviews were conducted with survey subjects or their proxies and
 hospital and nursing home records were collected.  Death certificates were
 obtained for deceased subjects.

Geographic coverage
      In the first National Health and Nutrition Examination Survey
 (NHANES I), data were collected from a national probability sample of the
 civilian noninstitutionalized population.  The 1982-84 NHANES I Epidemiologic
 Followup Study population is comprised of the 14,407 examined persons aged
 25-74 years at the time of NHANES I and the 1986 study is comprised of the
 5,677 persons aged 55-74 at NHANES I.
Time coverage
      Data collection for the NHANES I Epidemiologic Followup Study was
 conducted from 19182 to 1984 and again in 1986.  The data collection period
 for its baseline study was 1971-75.
Technical characteristics
      Each data file is rectangular and contains fixed-length records.  The
 data tape characteristics for each NHEFS data tape are as follows:

DATA ON VITAL EVENTS

General survey description
      The National Center for Health Statistics promotes uniform collection of
 birth, death, fetal death, marriage, and divorce records in a national
 registration system; analyzes and interprets official vital statistics;
 integrates technical and legal aspects of the vital registration system;
 conducts surveys to expand the scope of national vital statistics beyond the
 data usually available from vital records; uses actuarial methods to
 construct annual life tables; and investigates the quality and reliability of
 data and methodology.
      The birth, fetal death, and death registration system of the United
 States covers the 50 States and the District of Columbia.  Data on marriages
 and divorces are not uniformly available for the United States.  The number
 of States covered by the marriage-registration area varied from 39 in 1968
 to 42 in 1987. The District of Columbia was included for all years.  The
 number of States covered by the divorce-registration area varied from 26 in
 1968 to 31 in 1987.
      Mortality, underlying cause of death, and multiple cause of death data,
 natality data, fetal death data, marriage data, and divorce data are
 available for the years 1968-87.  Linked data for births and infant deaths
 are available for the birth cohorts of 1983-85.  The data can be used only
 for statistical purposes; no identifiers of persons or establishments are
 included.

NATALITY DATA

Specific survey description
 Natality data include all births occurring within the United States.
 Births occurring to U.S. citizens outside the United States are not included.
Data tape description
      Data are obtained from certificates filed for births occurring in each
 State.  Data were obtained from a 50-percent sample of certificates during
 1968-71.  Stating in 1972 all records were included for States that
 participated in the Vital Statistics Cooperative Program (VSCP).  The number
 of States participating in the VSCP increased from 6 in 1972 to 46 in 1984;
 beginning in 1985, all States and the District of Columbia participated.
      Three data tape files are available for each year.  Tables 4 and 5 list
 the items included in each data file.  The detailed files include on tape
 record for each birth in the sample.  Birth certificate numbers are not on
 the tapes.  Data on the local area summary and the State summary files have
 been weighted and represent a total count of births.  Table 4 lists the items
 in these files.  A discussion of the sample design, sampling errors, and a
 table of standard errors are part of the documentation of these files.
Geographic coverage
      Place of birth is classified by State and county.  In residence
 classification, all births are allocated to the usual place of residence of
 the mother as reported on the birth certificate and are classified by State,
 county, and city.
      For data years 1968-78, cities of 250,000 persons or more are
 classified. Beginning with 1979, cities of 100,000 persons or more are
 classified.
      Geographic classification for 1968-69 is based on the 1960 census
 enumeration.  Geographic classification for 1970-81 is based on the 1970
 census enumeration.  Geographic classification for 1982-87 is based on the
 1980 census enumeration.
Time coverage
 Data tapes are available for individual years from 1968 to 1987.
Technical characteristics
 All natality data files are fixed-length blocked files.  Specific
 characteristics for each file and year are listed in table 5.
Documentation contents
      Each data tape package contains the necessary documentation, including
 tape content and technical information, needed to access the data.  Control
 total tables are also included.

      Reports that relate to the data are available in Vital and Health
 Statistics Series 21, Supplements to the Monthly Vital Statistics Report, and

MORTALITY DATA:  Mortality-underlying cause of death

Specific survey description
      Mortality, underlying cause-of-death data, include all deaths occurring
 within the United States.  Deaths of U.S. civilians and deaths of member of
 the Armed Forces occurring outside the United States are not included.
Data tape description
      Data are obtained from certificates filed for deaths occurring in each
 State.  Data were obtained from all certificates for 1968-71 and for 1973-87.
 Data were obtained from a 50-percent sample of certificates for 1972.  Causes
 of death for 1968-78 were coded according to the Eighth Revision,
 International Classification of Diseases, Adapted.  Causes of death for
 1979-87 were coded according to the Ninth Revision, Internal Classification
 of Diseases.
      Three underlying cause-of-death data files are available for each year.
 The detailed files include one tape record for each death occurring in the
 data year except for 1972.  For 1972, the file includes one tape record for
 each death in the 50-percent sample.  Death certificate numbers are not on
 the tapes.  Data on the local area summary files and the cause of death
 summary files have been weighted and represent a total count of deaths.
 Tables 6 and 7 list the items in these files.
Geographic coverage
     Place of death is classified by State and county.  In residence
 classification, all deaths are allocated to the usual place of residence as
 reported on the death certificate and are classified by State, county, and
 city.
     For data years 1968-78, cities of 250,000 persons or more are classified.
 Beginning with 1979, cities of 100,000 persons or more are classified.
     Geographic classification for 1968-69 is based on the 1960 census
 enumeration.  Geographic classification for 1970-81 is based on the 1970
 census enumeration.  Geographic classification for 1982-87 is based on the
 1980 census enumeration.
Time coverage
  All mortality data files are fixed-length, blocked files.  Specific
  characteristics for each file and year are listed in table 8.
Technical characteristics
 All mortality data files are fixed-length, block files.  Specific
 characteristics for each file and year are listed in table 8.
Documentation content
     Each data tape package contains the necessary documentation, including
 tape content and technical information, needed to access the data.  Control

Summary Information
 All data items in the detail are in EBCDIC code.  The stub portion of all
 summary records consists of EBCDIC codes, and the spread portion consists of
 a series of full-word binary fields containing numbers of deaths.

 Beginning in 1970 the place of residence for decedents who were non residents
 of the United States has been coded to the country of residence (8
 categories). Formerly these deaths were considered resident deaths of the
 place of occurrence. The local area and cause-of-death summaries exclude data
 for nonresidents of the United States.

 Causes of death for 1968-78 were coded according to the Eighth Revision,
 International Classification of Diseases, Adapted.

 MORTALITY-MULTIPLE CAUSE OF DEATH
 Specific survey description
 Mortality, multiple cause-of-death data, include all deaths occurring within
 the United States.  Deaths of U.S. civilians and deaths of member of the
 Armed Forces occurring outside the United States are not included.
 Data tape description
      Data are obtained from certificates filed for deaths occurring in each
 State.  Data were obtained from all certificates for 1968-71 and for 1973-87.
 Data were obtained from a 50-percent sample of certificates for 1972.  Causes
 of death for 1968-78 were coded according to the Eighth Revision,
 International Classification of Diseases, Adapted.  Causes of death for
 1979-87 were coded according to the Ninth Revision, Internal Classification
 of Diseases.
      Three underlying cause-of-death data files are available for each year.
  The detailed files include one tape record for each death occurring in the
 data year except for 1972.  For 1972, the file includes one tape record for
 each death in the 50-percent sample.  Death certificate numbers are not on
 the tapes.  Data on the local area summary files and the cause of death
 summary files have been weighted and represent a total count of deaths.
 Tables 6 and 7 list the items in these files.
Geographic coverage
      Place of death is classified by State and county.  In residence
 classification, all deaths are allocated to the usual place of residence as
 reported on the death certificate and are classified by State, county, and
 city.
      For data years 1968-78, cities of 250,000 persons or more are
 classified. Beginning with 1979, cities of 100,000 persons or more are
 classified.
      Geographic classification for 1968-69 is based on the 1960 census
 enumeration.  Geographic classification for 1970-81 is based on the 1970
 census enumeration.  Geographic classification for 1982-87 is based on the
 1980 census enumeration.

FETAL DEATH DATA

Specific survey description
     Fetal death data are obtained from all reports of fetal death received
 from the 50 States and the District of Columbia for fetal deaths occurring
 in those areas.  Fetal deaths occurring to U.S. citizens outside the United
 States are not included.
Data tape description
General Information
    Registration area requirements for reporting fetal deaths vary.  Most of
 these areas require reporting fetal deaths of gestations of 20 weeks for more
 while some of these areas require reporting of all periods of gestation.
 There is substantial evidence that not all fetal deaths for which reporting
 is required are reported.
    A detailed data tape file is available for each year 1982-87 and includes
 one tape record for each report of fetal death received by NCHS.
    Fetal Death report numbers are not on the tape.  Table 15 lists the items
 in this file.

LINKED BIRTH/INFANT DEATH DATA

Specific survey description
     The birth cohort linked file of live births and infant deaths (numerator)
 includes linked vital records for births and deaths that occurred in the
 United States to U.S. residents and to U.S. nonresidents.  Excluded are
 deaths that occurred outside the United State to infants born in the United
 States, deaths that occurred in the Untied States to foreign-born infants;
 and births and deaths that occurred outside the United States to U.S.
 residents.
     The denominator file includes records for all births occurring within he
 United States.  Births occurring to U.S. citizens outside the United States
 are not included.
Data tape description
     The linked birth/infant death data set is comprised of two distinct
 files: (1) the numerator file comprised of linked birth and infant death
 statistical records; and (2) the denominator file which contains the National
 center for Health Statistics (NCHS) natality statistical records; and in
 addition, a small number of statistical records for late-filed birth
 certificates, and, for the 1983-84 cohorts, other birth certificates, from
 selected States were needed to match to infant death records.  The
 denominator file is not the same as the NCHS natality statistical file.
     The linked file is comprised of linked vital records for infants born in
 a given year who died in that year or the next year before their first
 birthday. The methodology used to create the national file of linked birth
 and infant death records takes advantage of two existing data sources:
 (1) State linked files for the identification of linked birth and infant
 death certificates; and (2) NCHS natality and mortality computerized
 statistical files.
     The national linked file was established by matching a file that
 contained only State-provided identifiers for linked certificates to the NCHS
 mortality statistical files and to the denominator file.  Matched birth and
 death records for the same infant were linked into a single statistical
 record to create the national linked file.
     The linked record data system provides a new national resource for
 research and analysis of infant mortality.  Included i the linked file is
 information from the death certificate of infants supplemented with
 information from the birth certificate, including characteristics of the
 infant at birth such as birth weight and gestational age, characteristics of
 the mother such as her age, educational attainment, and marital status, and
 information about prenatal care.
 **Table 17 lists the items in this file.
Geographic coverage
     Place of birth and place of death are classified by State and county. In
 residence classification of the birth, all births are allocated to the usual
 place of residence of the mother as reported on the birth certificate and are
 classified by State, county, and city.  In residence classification of the
 death, all deaths are allocated to the usual place of residence of the
 decedent as reported on the death certificate and are classified by State,
 county, and city.
     Counties of 250,000 persons or more and cities of 250,000 persons or more
 are classified in the linked data set.  Geographic classification for the
 linked data set is based on the 1980 census enumeration.
Time coverage
     Data tapes are available for the birth cohorts of 1983-85.

NATIONAL MORTALITY FOLLOWBACK SURVEY

General survey description
     The 1986 National Mortality Followback Survey (NMFS), supplements
 information from death certificates in the vital statistics file with
 information on important characteristics of the decedent.  These include use
 of health services prior to death, socioeconomic status, aspects of life
 style, health services experience prior to death, and other factors that may
 affect when and how death occurs.  Supplemental information is obtained from
 a variety of sources; e.g., a followback survey of informants (for example,
 spouse, child, and/or other next of kin) identified on the death certificate
 filed in State and independent registration areas, and information from
 hospital and other institutions used i the last year of life.  Reflecting
 these interests, the three broad foci of the survey are (1) socioeconomic
 status and mortality, (2)associations between risk factors and mortality,
 and (3) health care sought and provided in the last year of life.  A major
 objective of the NMFS is to examine the reliability of items reported on the
 death certificate by comparison of these items with the same items reported
 by the survey respondent.  This include age, race, veteran status,
 occupation, and industry.
Data tape description
     The tape consists of four types of linked records for 18,733 decedents:
 (2)data from death certificates, (2) 24 page informant survey questionnaire,
 (3) 16 page nursing home, hospital, and hospice questionnaire, and (4) the
 facility abstract record.  The NMFS is a nationally representative sample of
 adults aged 25 and over who died in 1986.  Data items contained in each
 record type are shown in table 19.
Geographic coverage
     While all 50 States and the District of Columbia granted their approval
 for use of a sample of their death certificates in the NMFS, deaths from
 Oregon are not included in the NMFS sample due to the State's respondent
 consent requirements.  Therefore, the data are representative of deaths to
 adult residents in the United States, excluding Oregon.  Death certificates
 were sampled from the 1986 Current Mortality sample (CMS).  The CMS is a ten
 percent sample of the States' death certificates, which NCHS receives about
 three months after the deaths occur.  Approximately 2,500 of the 18,733
 sample death certificates from the CMS were selected with certainty to meet
 specific research needs.
Time coverage
  Survey data are only available for 1986.  Another NMFS is planned for 1992.
Technical characteristics
    The data tape was generated on an IBM 3031.  The code scheme is numeric/
 alphabetic/blank.  Labels are Standard label.  The density of 6,250 and the
 record format is blocked, fixed.

NATIONAL NATALITY AND MORTALITY SURVEYS

General survey description
     All of the surveys in this group are called "followback" surveys because
 they follow back one or more informants identified on vital records.  There
 are three National Natality Surveys (NNS's) which cover births to married
 women in the years 1964-66, 1967-69, and 1972.  The 1964-66 NNS includes
 such topics as pregnancy history, birth expectations, family composition,
 employment status, health insurance coverage, and selected socioeconomic
 variables (table 20).  In the 1967-69 NNS, several new variables were
 introduced, including additional items relative to employment of the mother,
 religious preference, prenatal and postnatal care, and cigarette smoking
 (table 21).  In 1968 and 1969 a variable was added on whether or not the
 mother had wanted to become pregnant with the sample child.  The 1972 NNS is
 similar in content to the 1964-66 NNS and 1967-69 NNS but does not include
 items on employment status, religious preference, or cigarette smoking.
 However, the 1972 NNS includes new data on maternal and infant health
 available from questionnaires sent to physicians and hospitals (table 22).
     A 1964-66 National Infant Mortality Survey (NIBS) was patterned closely
 after the 1964-66 NNS, which also provides denominators for the 1964-66 NIBS.
 because the data tapes contain multiple records per sample child, the number
 of records is not the same as the number of sample children or single cases.
 Table 23 lists the items on the data tapes.
     Separate data tapes are available for each year of the 1967-69 NNS.
 Combined 3-year tapes are available for the 1964-66 NNS and 1964-66 NIBS. A
 combined tape is not available for the 1967-69 NNS.
     The 1966 -68 National Mortality Survey (NMS) collected data on the
 smoking habits of decedents aged 35-84.  Further information was gathered on
 household composition, family income, and assets for decedents aged 50 and
 over.  Only a combined tape is available for the 1966-68 NMS; the tape
 summary can be seen in table 24.

Summary Information
    In the 1980 national Natality Survey and 1980 National Fetal Mortality
 Survey (NNS/NFMS), four groups associated with the sampled deliveries-
 married mothers, hospitals, attendants at delivery, and other medical
 providers of radiation during pregnancy-responded to questionnaires.  The
 medical data were collected for married and unmarried mothers in the
 NNS/NFMS.  The 1980 NNS and NFMS are only available on one combined tape,
 and cannot be purchased separately.  A list of over 100 papers or reports
 utilizing the data is available for the Natality Statistics Branch.  These
 findings include electronic fetal monitoring in relation to cesarean section
 delivery, trends in maternal and infant health factors associated with low
 infant birth weight, radiation procedures performed during pregnancy, infant
 health consequences of childbearing by teenagers and older mothers, social
 and clinical correlates of postpartum sterilization, and maternal smoking and
 drinking behavior before and during pregnancy (table 25). Certain additional
 infant mortality information obtained from the National Death Index is not
 on the public use tape, but is available through the Natality Statistics
 Branch.
      The 1986 National Mortality Followback Survey (NMFS) includes a sample
 of 18,500 death certificates of persons ages 25 years and older who died in
 the United States in 1986.  A next of kin identified on the death certificate
 or some other knowledgeable informant is the respondent.  The survey is
 designed to supplement the information on the death certificate.  Additional
 questions are asked about socioeconomic status, including family income,
 assets, and education. Other major topic ares are the use of health care
 resources in the last year of life, disability prior to death, and health
 habits such as smoking and drinking alcoholic beverages.
      A major purpose of the 1986 NMFS is to examine the reliability of items
 reported on the death certificate by comparing these items with the same
 items reported by the survey respondent.  Items that will be compared include
 age, race, veteran status, and occupation and industry.
      While all 50 States granted their approval for use of a sample of their
 death certificates in the NFMS, Oregon is not included in the NMFS, Oregon is
 not included in the NMFS.
      The facility phase of the 1986 NMFS involves mailing  a Facility
 Abstract Record (FAR) to those health facilities in which a decedent had
 spent at least one night in the year prior to death.  The FAR obtains the
 admission date discharge data, diagnoses, and procedures for each facility
 stay.
      By the end of 1988, the Center plans to release a public use data tape.
 Data from the facility phase of the NMFS should be available in 1989 or 1990.

Summary Information
 A National Maternal and Infant Health Survey will be conducted by the
 National Center for Health Statistics in 1988.  This survey will consist of
 three components:  a natality survey, which will be sampled from certificates
 of  live birth; a fetal mortality survey, which will be sampled from reports
 of fetal death; and an infant mortality survey, which will be sampled from
 infant death certificates.  The major areas of investigation will be:  causes
 related to low- birth-weight infants and infant deaths; barriers and
 facilitators to prenatal care; the effects of maternal smoking, drinking, and
 drug use on pregnancy outcome; the effects of sexually transmitted diseases
 (STD's including AIDS) on pregnancy outcome; and use and evaluation of public
 programs, such as WIC and Medicaid, by mothers and infants.  Data will be
 collected throughout 1988 =-89. A public use data tape for these data will
 probably be available by 1992.

COMPRESSED MORTALITY FILE
General program description
      The Compressed Mortality File (CMF), formerly the Mortality Surveillance
 System, is a county-level national mortality and population data based from
 which differential mortality trends can be easily and efficiently examined.
 The CMF spans the years 1968-85, the period covered by the 8th Revision and
 the first 7 years of the 9th Revision of the International Classification of
 Diseases (ICD).
      The mortality data base of the CMF is derived from the U.S. Microdata
 death records from the National Center for Health Statistics (NCHS) for this
 period.
      The 35 million 159-160 byte records were reduced to 15 million 23-byte
 records.  The variables included on the condensed file are (1) county of
 residence, (2) year of death, (3) color (White, all other), (4) sex, (5) age
 group at death (15 age groups), and (6) underlying cause of death (4 digit
 ICD code).  The population data base is derived from annual estimate for each
 U.S. county be age, color, and sex, prepared by the Bureau of the Census,
 with modifications by NCHS.
Data tape description
      The information on the mortality tapes is based on NCHS mortality files
 for the years 1968-85.  The source files were stored on 126 tapes with a
 total of 35 million 159- or 160-byte records, one for every death recorded in
 the United States during this period.  (For the year 1972, the data are based
 on a 50-percent sample and are weighted by a factor of 2.)  The sources have
 been condensed to a two-tape file of approximately 15 million  23-byte
 records.
       Specific age was recoded into 15 age groups and full date of death to
 year of death.
      The variables included on the condensed file are:  (1) county of
 residence, (2) year of death, (3) color (white, all other), (4) sex, (5) age
 group at death, and (6) underlying cause of death (4-digit ICD code).  The
 number of records was reduced by counting records identical with respect to
 underlying cause of death, age group at death, year of death, color, sex, and
 county of residence and then adding a count field.
      The population data base of the CMF is derived from annual estimates for
 each U.S. county by 5-year age group, color (white, all other), and sex. The
 estimates for 1970-82 were prepared by the Bureau of the Census and modified
 by NCHS.  The estimates for 1968-69, and 1883-85 were derived by NCHS using
 linear extrapolation.  To permit the calculation of infant mortality rates,
 NCHS live-birth data were substituted for the estimate of the population
 under 1 year of age.

 Data on health resources utilization

NATIONAL HOSPITAL DISCHARGE SURVEY (NHDS)
General survey description
     The National Hospital Discharge Survey is a continuous nationwide survey
 of inpatient utilization of short-stay hospitals.  Survey data are abstracted
 form sampled medical records of inpatients discharged from a national sample
 of non-Federal short-stay hospitals (see table 26).
Data tape description
      Medical record data include age, sex, race, marital status, expected
 source of payment (1977 on), discharge status, admission and discharge dates,
 and length of stay for discharged patients.  Hospital characteristics include
 region of country, bedsize, and type of ownership.  Diagnostic data include
 up to five diagnoses per patient from 1970-78, and up to seven diagnoses
 after 1978.  Data on procedures include a maximum of three procedures per
 patient from 1970-78 and up to four procedures after 1978.  From 1970 to 1978
 diagnoses and procedures were coded according to the Eighth Revision
 International Classification of Diseases, Adapted for Use in the United
 States (ICDA), with certain modifications.  Beginning in 1979 the
 International Classification of Diseases, Ninth Revision, Clinical
 Modification (ICD-9-CM) was used to code diagnoses and procedures.  The tapes
 contain no confidential data.
Geographic coverage
     The National Hospital Discharge Survey is a nationwide survey, but allows
     analysis at the Census division level (region level in 1988).
Time coverage
     Data tapes for calendar years 1970-88 are now available.
Technical characteristics
General Information
     Separate files are prepared fore each annual survey.  Each file contains
 approximately 200,000 records which have a fixed length format (150
 characters for 1970-78, 200 characters for 1979-85, and 250 for 1986-88).

NATIONAL HOSPITAL DISCHARGE SURVEY: DATA ON DISKETTE
Data diskette description
     Data on diskettes offer microcomputer users the opportunity to
 manipulate, analyze, and display data using standard software packages.  The
 National Hospital Discharge Survey (NHDS) diskettes contain data on hospital
 utilization by age and sex of patient and geographic region of the hospital
 for conditions diagnosed and surgical and nonsurgical procedures performed.
 Data on hospital discharges by diagnosis-related groups also are presented.
 Population rates also can be calculated.  All data are crossed by four age
 groups or sex or regions. The data diskettes are intended as an information
 source for researchers and others who need data for detailed diagnostic,
 procedures, and DRG categories but do not need the record-level detail
 provided by the entire data tape.
     The data diskettes and documentation provide an easy one-step automated
 access to a wide range of statistics on hospitalization produced by the
 survey. The data diskettes are a complete package including software for
 accessing the database files, for computing rates of selected population, and
 for creating smaller files for use with other software packages.
     The NHDS consists of data abstracted from face sheets of the medical
 records for sampled inpatients discharged from a national sample of
 non-Federal short-stay hospitals and are weighted to produce national
 regional estimates. Approximately 500 hospitals and 190,000 records are
 included in the sample each year.
Geographic coverage
    The National Hospital Discharge Survey is a nationwide survey, but allows
    analysis at the Census regional level.
Time coverage
     Diskettes are available for calendar years 1985-88.

NATIONAL AMBULATORY MEDICAL CARE SURVEY

General survey description
     The National Ambulatory Medical Care Survey (NAMCS) is a nationwide
 survey designed to meet the needs for objective, reliable information about
 the provision and use of ambulatory medical care services int he United
 States. Findings are abased on a sample representative of all ambulatory
 office visits to physicians in the United States who are engaged in patient
 care in an office setting, physicians in government service, and physicians
 inn the specialties of anesthesiology, pathology, and radiology are excluded
 from the survey.
     Specially trained interviewers visited the physicians prior to their
 participation in the survey, provided them with survey materials, and
 thoroughly instructed each physician and staff member in the methods and
 definitions to be used.  During a randomly assigned 7-day period, data for a
 systematic random sample of visits were recorded by the physicians or their
 staff on an encounter form provided for that purpose.  Data were obtained on se
 characteristics of patients, several clinical aspects of the visit, including
 medications (if any), and physician specialty and type of practice.
     There are two public-use tapes available from the NAMCS:  one dealing
 with patient visit information and a second dealing with Drug Mentions.  The
 second is limited to information concerning only those visits involving
 drugs.

Patient visit data tape description
     Data are arranged by Patient Record Form.  Each tape record is a complete

Drug mention data tape description
     The "drug tape" is a collection of data concerning only those office
 visits where one or more medications were ordered, administered, or provided.
  Data are arranged by drug record, one for each drug mentioned or entered on
 the encounter forms.  A single office visit in 1985 could have up to five
 drugs mentioned on the encounter form, and thus have up to five separate
 records on the drug tape. On the other hand, if there were no drugs mentioned
 on the encounter form for a particular visit there will be no record on the
 drug tape for that office visit.
     Each drug record is a complete description of the office visit containing
 all the items in the following summary, including the statistical weight for
 inflating the drug mention sample to reflect (drug) annual utilization in
 private office-based practice in the United States.  All data on the tape are
 in EBCDIC code.  Each data tape package contains one tape volume and the
 necessary documentation.

NATIONAL NURSING HOME SURVEY

General Survey description
     The National Nursing Home Survey (NNHS) is a continuing series of
 national sample surveys of nursing homes, their residents, and their staff.
 To date, three nursing home surveys have been conducted, the firs tin
 1973-74, the second in 1977, and the third in 1985.  These three surveys
 were preceded by a series of surveys between 1963 and 1969 which were called
 the "resident places" surveys. While each of these past surveys emphasized
 different topics, they all provided some common basic information about
 nursing homes, their residents, and their staff.
     The two most recent surveys, 1985 and 1977, were similar in scope in that
 they both included nursing care homes, personal care homes (with and without
 nursing), and domiciliary care homes.  These surveys represent a broadening
 in scope over that of the 1973-74 survey which excluded facilities providing
 only person care of domiciliary care.  However, because personal and
 domiciliary care homes constitute such a small proportion of the 1977 and
 1985 surveys, no special adjustments need to be made when comparing the three
 surveys. besides providing national estimates of nursing homes, the 1977 NNHS
 was supplemented with additional nursing homes to provide reliable estimates
 for selected States. The States for which estimates are available
 (California, Illinois, Massachusetts, New York, and texas) cover one-third of
 the nursing home population.  Data from the three previous surveys of nursing
 homes, conducted during May through December 1977, August 1973 through April
 1974, and June through August 1969 are also available.
     The data were sampled using a stratified two-stage probability design.
 The first stage was a selection of facilities; the second was a selection of
 residents and employees of the sample facilities.  In the 1985 survey, only
 registered nurses were sampled. The sampling frame for residents was the
 total number of residents on the register of the facility on the evening
 prior to the day of the survey.  The sampling frame for employees was the
 list of all staff members including those employed by contact.  Only staff
 members involved in direct patient care (administrative, medical,
 therapeutic, and nursing staff) were sampled.  Survey data were collected
 using a combination of personal interview and self-enumerated forms.
 Additional information about both current and discharged residents was
 obtained in a telephone interview with a relative in the 1985 survey only.
     The 1985 and 1977 NNHS differed from previous surveys by the inclusion of
 an additional sample of discharges from the nursing home during the preceding
 year. The sample of discharges (both alive and dead) was included in the NNHS
 to provide information on duration of stay in nursing homes and the
 characteristics of persons spending a relatively short time in the facility.

Data tape description
     All data except the next-of-kin telephone followup from the 1985 survey
 will be on one tape (table 27).  The next-of-kin file and two additional
 telephone followup files will be available in 1990.  See National Nursing
 Survey Followup for details.  The package of data tapes form the 1977 survey
 is available in two versions:  national and State.  The national version
 includes only those cases selected in the national sample, while the State
 version includes only those cases selected for California, Illinois,
 Massachusetts, New York, and Texas. Thus the record weights on the national
 tapes inflate to national estimates of nursing homes, residents, etc., while
 the record wights on the State tapes inflate to State estimates. The package
 of tapes in both the national and State versions consists of the facility
 file, resident file, discharge file, and staff file (tables 32 and 33).  The
 tape layouts for all of these files are the same for both the national and
 State versions.     The package of tapes for the 1973-74 survey consists of
 the facility file, resident file, staff control record, and staff file
 (table 34).  The package of data tapes available from the 1969 survey
 consists of the facility file and the resident file (table 35).  Although the
 design of the 1979 survey was similar to that for 1973-74, much less data was
 collected in 1969.     For each survey year, all tapes include a facility
 number common across files to allow linkage between files.  The tapes have
 been edited to ensure consistency and to adjust for nonresponse.
Geographic coverage
     The data represent nursing homes, their residents and staff int he
 conterminous United States.  Geographic identifiers are also available region
 (all files), SMSA indicator (1973-74 and 1985 only), and DHHS administrative
 region (1977 and 1985 only).
Time coverage
     Tapes are available for 1985, 1977, 1973-74, and 1969.
Technical characteristics
 Each file is rectangular and contains fixed-length character records.  See
 tables 32-35 for the record length, block size, and number of records for
 each file.
Documentation contents
     For each survey year the tapes are sold as a complete package.  Tape
 layouts for each file in the package are included.

NATIONAL NURSING HOME SURVEY NEXT OF KIN COMPONENT
Complete Title
 National Nursing Home Survey:  Next-of-Kin Component and Followup
General survey description
     The Next-of-Kin (NOK) is one of the six components of the 1985 National
 Nursing Home Survey (NNHS).  The NOK was designed to collect information on
 factors affecting patterns of nursing home and health care facility
 utilization by supplementing the current and discharged resident components
 of the study. The NOK was used to obtain information that was not  readily
 available from patient records or other sources in the home.
     Unlike the other components of the 1985 NNHS, the NOK Component was
 conducted using a Computer-Assisted Telephone Interview (CATI) system.
 Interviewing occurred between October 1985 and October 1986.  NOK interviews
 were completed for 9,084 subjects.  If the subject could not participate,
 interviews with proxy respondents (primarily next-of-kin) were conducted.
 Administrators or other facility personnel were contacted for a few subjects
 who were in facilities and for whom no next-of-kin could be located.
     The National Nursing Home Survey Followup (NNHSF) is a longitudinal study
 which follows the cohort of current residents and discharged residents
 sampled from the 1985 NNHS.  The National Nursing Home Survey Followup
 extends the period of observation of these utilization patterns by
 approximately four years after the baseline nursing home interview.  The
 NNHSF is being conducted in three Waves.  Wave I was conducted between August
 and December 1987, Wave II between July and November 1988, and Wave III was
 begun in February 1990.  The expected completion date for Wave III is July
 1990.
     The same questionnaire and CATI system were used for both Waves.  If the
 subject could not participate, interviews, with proxy respondents (primarily
 next-of-kin) were conducted.  For those subjects in facilities,
 administrators or other facility personnel were interviewed.
     Approximately 6,600 subjects were eligible for Wave I.  Based on the
 results of Wave I, about 4,000 subjects were eligible for Wave II
 interviewing.  The vital status of the subject (alive/deceased) at the time
 of the Wave I interview and the response status to the Wave I questionnaire
 (completed/not completed) were used for identifying these subjects.  The same
 procedures used in wave I for locating respondents to interview were again
 used in Wave II.      Wave I and Wave II of the NNHSF will be released in the
 summer of 1990.
Data tape description
     The Next-of-Kin file, the NNHSF Wave I, and NNHSF Wave II files are each

NATIONAL MASTER FACILITY INVENTORY

General survey description
     NCHS maintains a computer file of selected characteristics of inpatient
 health facilities.  This file, called the National Master Facility Inventory
 (NMFI), is a comprehensive list of facilities in the United States that
 provide medical, nursing, personal, or custodial care to groups of unrelated
 persons on an inpatient basis.  Earlier files included hospital, nursing and
 related care homes, and other inpatient health facilities.  The most recent
 files include only nursing and related care homes.  In 1986 the name of the
 Survey was changed to the Inventory of Long-Term Care Places since the Survey
 was expanded to include facilities for the mentally retarded.
Data tape description
     Each file contains the names and address of the facility.  Other data
 items vary by type of facility.  See tables 36 and 37 for a list of items
 available on each file.
Geographic coverage

NATIONAL INVENTORY OF FAMILY PLANNING SERVICES

General survey description
     NCHS maintains a computer file of selected characteristics of facilities
 providing medical and nonmedical family of Family Planning Services.  It is
 a comprehensive listing of planning services.  This file is called the
 National Inventory all facilities or service sites (excluding private
 physician's offices) in which some type of family planning service, whether
 medical or nonmedical, is provided.  The file is maintained on computer tape
 and contains the name and address for each facility.

Data tape description
     Data are given on the physical location of the service sites, their
 primary purpose and operating responsibility, the number of patients served,
 medical and ancillary services provided, and the contraceptive methods
 available.  Data are based on a mail survey taken by the National Inventory
 of Family Planning Services of 11,340 known family planning service
 providers.
     Copies of the data tape, in addition to printouts of the data, are
 available from NCHS.  Neither the tape nor the printout contains confidential
 data.  The cost for each tape is $125.000; the printout costs $150.00.  It
 takes about four weeks for delivery of tape or printout.
Documentation contents
     Documentation consists of copies of the tape layout and questionnaire.
 When a data item was missing from the questionnaire, an imputed value was
 derived. These values are flagged so the user is aware that an imputation was
 performed.
Time coverage
     Tapes are available for 1974 and 1975.
Related reports

NATIONAL FAMILY PLANNING REPORTING SYSTEM

General survey description
     The National Center for Health Statistics maintains a computer file of
 1980 sample survey called the National Reporting System for Family Planning
 (NRSFPS). The NRSFPS covers all family planning visits to nonmilitary sites
 in the United States and some of its territories that offer medical family
 planning services.
     Begun in 1972, the NRSFPS collected data on visits to family planning
 service sites in the United States and some of its territories.  From 1972
 through June 1977, the survey was conducted as a complete enumeration,
 collecting information for every family planning visit at every participating
 site.  From July 1, 1977, through 1980, however, the system was conducted as
 a sample survey.
Data tape description
     The data tape of the NRSFPS includes medical family planning visits
 occurring in nonmilitary clinics.
Time coverage
     The time frame covered by this survey is from July 1977 to 1980.

Technical characteristics
 The 1980 NRSFPS estimates are based on a stratified two-stage sample
 design.

 The first stage sampling consists of a list of family planning service sties
 participating in the 1976 full-count NRSFPS augmented by other Federal
 agencies.

 In the second stage, family planning visits at each sample site were
 systematically selected.

Documentation contents
     Documentation for users of the data tapes of NRSFPS is included in Public
 Use Tape Documentation, 1980 National Reporting System for Family Planning
 Services, April 1983.

NATIONAL SURVEY OF FAMILY GROWTH

General survey description
     The National Survey of Family Growth was initiated to provide current
 information on childbearing, contraception, and closely related aspects of
 maternal and child health.  It is similar in design and purpose to the Growth
 of American Families GAF) studies conducted by the Scripps Foundation and the
 University of Michigan in 1955 (GAF-I) and 1960 (GAF-II) and to the National
 Fertility Surveys (NFS) conducted by the Office of Population Research,
 Princeton University, in 1965 (NSF-I) and 1970 (NFS-II).  These surveys
 provide comparable data on trends in many of the factors affecting the birth
 rate and reproductive health from 1955 to the 1980's.
     Topics covered in the interview include:  the month and year of first
 intercourse (Cycles III and IV only): pregnancy, contraceptive, and marital
 histories; employment; occupation; child care; fecundity and sterility;
 prenatal medical care; family planning services; birth expectations;
 ethnicity; education; religion; and income.  Information on contraception was
 obtained for each pregnancy interval, and detailed contraception information
 was obtained for each month in the 3 years before the interview.  A series of
 questions was also asked to establish whether or not each pregnancy was
 wanted by the husband and wife just before conception.
     The file consists of a "respondent" or "woman" record, followed by a
 "pregnancy interval" record for each of the woman's pregnancies, if nay.
 (See table 39.)
     Each record contains a weight to be used in obtaining national estimates
 from the data.  The complex sample design makes computation of variance
 estimates difficult, but reprots published by NCHS contain charts and
 parameters form which standard errors for certain statistics may be
 calculated.  (See Series 2, Numbers 76, 87, and 98.)
     Each data tape package contains one tape volume and all necessary
 documentation, including the tape contents manual, and a description of the
 sample design weighing and variance estimation.

Time coverage
     The National Survey  of Family Growth (NSFG) is a periodic survey of
 women 15-44 years of age in the civilian noninstitutionalized population of
 the coterminous United States.  In Cycles I (1973) and II (1976), the survey
 was limited to women who had ever been married or had their own children
 living with them; in 1982 and 1988, all women 15-44 years of age were
 included.  Data are collected from a probability sample of these women in
 person in their own households using a pre-printed questionnaire.  Sample
 sizes were 9,797 in Cycle I (1973), 8,611 in Cycle II (1976), 7,969 in Cycle
 III (1982), and 8,450 in Cycle IV (1988).

Data years available
     Tapes for Cycle I (1973), II (1976), III (1982), and IV (1988) are now
 available.

Related reports
     Over 100 reports and articles have been published using NSFG data.
 Results have been published in Advance Data Numbers 9, 10, 11, and 26 (based
 on Cycle I); 36, 43, 45, 55, 56, 58, 59, and 61 (based on Cycle III); and
 102, 103, 104, 107, and  108 (based on Cycle III); and in Series 23 of Vital
 and Health Statistics, Numbers 1-16; Series 2, Numbers 76, 87, 91, and 98;
 and many journal articles. A current listing of NSFG publications may be

NATIONAL MEDICAL CARE UTILIZATION AND EXPENDITURE SURVEY

General survey description
     National Medical Care Utilization and Expenditure Survey (NMCUES) was a
 panel survey designed to collect data about the U.S. civilian
 noninstitutionalized population in 1980.  Information was obtained on heath,
 access to and use of medical services, associated charges and sources of
 payment, and health insurance coverage.
     NMCUES consisted of three survey components.  The National Household
 Component comprised about 6,000 randomly selected households that were
 interviewed five times during 14 months in 1980-81.  The State Medicaid
 Household Component consisted of about 4,000 households selected from the
 Medicaid eligibility files in California, Michigan, New York, and Texas
 (1,000 households in each State).  Each household was interviewed five times
 during 14 months in 1980-81.  The Administrative Records Component was used
 to obtain information on program eligibility and payments for Medicare for
 persons receiving Medicare and Medicaid.

Data tape description
     The NMCUES Public-Use Data Files contain only respondent data from the
 National Household Survey.  These data are from a sample of 17,123 persons
 representing the civilian noninstitutionalized population of the United
 States. The public-use file consists of six fixed-length files:

 Person............Contains one record for each sample person.  Each record
                   includes the person's survey response status; demographic
                   characteristics; health insurance coverage; number of
                   visits and other medical events and associated charges;
                   limitations and disabilities and related conditions; and
                   employment, income, and data on usual source of care.

 Medical visit.....Contains one record for each visit to an emergency room,
                   hospital outpatient clinic, and physician or other
                   practitioner's office.  The data in the file include place
                   of visit, type of physician or nonphysician see, type of
                   services provided, conditions causing or associated with
                   the visit, tests done during the visit, associated
                   charges, and sources of payment.

 Dental visit......Contains one record for each dental visit reported.  Data
                   on the file include services provided, associated visit
                   charges, and source of payment.

 Hospital stay.....Contains one record for each reported short-term hospital
                   admission with a discharge date in 1980.  The file
                   contains date of admission and discharge; International
                   Classification of Diseases (ICD) codes and recodes of
                   conditions causing the hospital stay; codes for surgical
                   procedures performed, other nonsurgical procedures,
                   charges, and sources of payment; and data on physicians
                   providing treatment during the hospital stay but who
                   billed separately.  These physician data include type of
                   physician, associated charges, and sources of payment.

NATIONAL SURVEY OF PERSONAL HEALTH PRACTICES AND CONSEQUENCES

General survey description
     The National Survey of Personal Health Practices and Consequences
 (NSPHPC) was conducted by the National Center for Health Statistics (NCHS)
 as part of the effort to meet the data needs of the prevention initiative of
 the U.S. Department of Health and Human Services.  The survey is a national
 probability sample selected using random-digit dialing techniques and was
 conducted in two waves of interviews among a panel of noninstitutionalized
 civilian persons 20-64 years of age inn the conterminous United States.
 Wave I was conducted in the spring of 1980.  In the second wave of the
 survey, 2,453 interviews (81 percent) were completed for the respondents
 interviewed in Wave I.  The NSPHPC replicates, in part, a 1965 study
 conducted among a sample of the adult residents of Alameda County, Calif., by
 the Human Population Laboratory of the California State Department of Health.

Data tape description
     Data are included on diet and exercise; sleeping; smoking; drinking of
 alcoholic beverages; weight status; dental hygiene; use of seat belts;
 changes in preventive health behavior due to illness; perceived health status
 and energy level; concern about health and feelings about capability of
 taking care of one's own health; use of preventive health services; use of
 medical and hospital care; behavior with respect to high blood pressure;
 disability status; frequency of colds and headaches; limitations on usual
 activities because of health; family heritage of longevity; work status,
 conditions of work with respect to hazards, stress, physical demands, and
 sick leave; participation in social groups and religious services; enjoyment
 of free time; number and closeness of friends and relatives; general
 psychological well-being; recent stressful life events; and sociodemographic
 information, such as age, sex, marital status, educational level, race, and
