Welch, Chief, Publications Branch Terence A. Drizd, Chief, Office Automation Branch ContentsINTRODUCTION 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 order a file on disc.

(Available for most computer products; U.S., Canada, and Mexico only) 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.

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.

Send indicated data sets to: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.Data tape description General Information Data tapes from the HHANES are generally organized by data collection method (e.g., Child Sample Person Questionnaire or Dental Examination), with applicable demographic and socioeconomic information included on each tape.

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.

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.

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.

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 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. Related reports Reports that relate to the data are available in Vital and Health Statistics Series 21, Supplements to the Monthly Vital Statistics Report, and Vital Statistics of the United States, Volume I, Natality. 3Contact Joseph D.

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.

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. Table 17.

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.

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. Table 20.

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. Table 22.

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. Table 24.

Contact Natality Statistics Branch (301) 436-8954 Room 840 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.

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).

Contact Robert Pokras (301) 436 7125 Room 950 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.

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.

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. Related reports More detailed discussion of the 1985 NNHS is in Series 13, Numbers 97, 98, 102, and 103. More detailed discussion of the 19767 NNHS, tables, and copies of the questionnaires are found in Series 13, Numbers 43, 48, 51, 53, and 54, and in Series 14, Number 25.

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.

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.

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.

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. Other health-related data 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.

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.
