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.

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.

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.

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.
Data tape description
Data tapes from NHANES I are organized by subject matter, with demographic
and socioeconomic information included where applicable.
Geographic coverage
Civilian noninstitutionalized U.S. population 1-74 years of age.
Time coverage
Data from both the main nutrition component and the augmentation portion of

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.

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.

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.

entire course of the survey: October 1959 to December 1962.
Documentation contents
Data tapes from NHES I are organized by subject. The person and
demographic characteristics tape is a master tape intended for use in
conjunction with any or all other data tapes in the set. It contains
demographic, socioeconomic, and geographic classification information not
available on most of the other data tapes, along with the sample weight for
each examined person. A uniform sequence file number on all data tapes
permits the user to merge any of the tapes. Data tape documentation packages
contain a brief description of NHES I, a file description, a detailed
description of data items, and detailed notes on items judged not to be self-
explanatory.

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.
Data tape description
NHEFS public use data tapes
1. Vital and tracing Status Tape - The 1982-84 version contains
tracing, vital status, and demographic data for all 14,407 NHEFS respondents
and the 1986 version contains the same type of information for the 5,677
elderly respondents.
2. Interview Tape - The 1982-84 version contains information collected
from the 12,220 subject and proxy interviews and the 1986 version contains
3,068 subject and proxy interviews of elderly respondents.
3. Health Care Facility Stay Tape - The 1982-84 version contains data
on 25,4366 overnight stays in health care facilities including diagnostic and
summary information abstracted from 18,085 hospital and 418 nursing home
records. The 1986 version contains the same information from 5,405 overnight
stays including information abstracted from 3,496 hospital and 413 nursing
home records.
4. Mortality Data Tape - These files contain death certificate
information for NHEFS decedents. The 1982-84 version includes the 1,935
records for NHEFS subjects collected ruing the 1982-84 followup period. The
1986 version includes 2,266 records for elderly decedents collected during
both the 1982-84 and 1986 followup periods. The death certificates are coded
according to ICD-9 multiple cause of death procedures.
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.

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

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.

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

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
description of the office visit containing all the items in the following
summary, including the statistical weight for inflating the sample visit to
reflect annual utilization of 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. See tables 28 and
29.
Geographic coverage

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
on separate reels. All files include a patient identification number common
across files to allow linkage between files. The tapes have been edited to
ensure consistency and to adjust for nonresponse.

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
Represent inpatient facilities in the entire United States. Geographic
detail available by State, county, and census region.
Time coverage
Hospital tapes are available for the years 1971-76. Nursing and related
care homes plus other inpatient facilities are available for the years 1971,
1973, and 1976. Only nursing and related care homes are available for 1980
and 1982. Nursing homes, residential facilities, and facilities for the
mentally retarded are available for 1986.

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.

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

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).

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.
Prescribed medicines and other medical expenses
......Contains one record for each prescription medicine and for
certain other medical expenses. Data in the file include
data of purchase, prescribed medicine codes, ICD codes and
recodes of conditions resulting in the purchase of
prescribed medicines or other medical expenses, and
sources of payment.
Condition file....Contains one record for each unique condition reported by
the respondent. The file contains ICD codes and recodes;
dates of onset of illness; counts of visit types,
prescribed medicines, and other medical expenses;
associated charges by condition; and reason for not seeing
a doctor for the condition (if applicable).

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
