Geographic coverage: United States

The basic purpose of the National Health Interview Survey is to obtain information about the amount and distribution of illness, its effects in terms of disability and chronic impairments, and the kinds of health services people receive. There are five types of records in the core survey, each in a separate data file. The variables in the Household File (Part 1) include type of living quarters, size of family, number of families in household, and geographic region. The variables in the Person File (Part 2) include sex, age, race, marital status, veteran status, education, income, industry and occupation codes, and limits on activity. These variables are found in the Condition, Doctor Visit, and Hospital Episode Files as well. The Person File also supplies data on height, weight, bed days, doctor visits, hospital stays, years at residence, and region variables. The Condition (Part 3), Doctor Visit (Part 4), and the Hospital Episode (Part 5) Files contain information on each reported condition, two-week doctor visit, or hospitalization (twelve-month recall), respectively. A sixth, seventh, and eighth file have been added along with the five core files. The Health Promotions and Disease Prevention Supplement is separated into three categories as follows: Child Safety/Infant Feeding (Part 6), Sample Person (Part 7), and Smoking (Part 8). These data files include questions on health and fitness awareness, general health habits, injury control, child safety and health, high blood pressure, stress, exercise, smoking, alcohol use, dental care, and occupational safety and health.

The purpose of the National Health Interview Survey (NHIS) is to obtain information about the amount and distribution of illness, its effects in terms of disability and chronic impairments, and the kinds of health services people receive. In 1985, the NHIS questionnaire included a special section, the Health Promotions and Disease Prevention (HPDP) supplement, that queried female respondents aged 18 through 44 who had had live births in the past five years about smoking during pregnancy. Their responses to the supplement are recorded in this dataset, along with other information about them derived from the HPDP and the 1985 core questionnaire (see HEALTH INTERVIEW SURVEY, 1985 [ICPSR 8668]). Questions on smoking history during pregnancy included current pregnancy status, whether the respondent had ever smoked 100 cigarettes, whether she currently smoked, time elapsed since the respondent last smoked regularly, number of cigarettes the respondent smoked per day, whether the respondent smoked during pregnancy, number of cigarettes smoked before learning of pregnancy, number of cigarettes smoked after learning of pregnancy, whether the respondent smoked during most of last pregnancy, and whether the respondent was ever advised by a doctor to quit smoking. Other variables in the HPDP focus on health and fitness awareness, general health habits, injury control, child safety and health, high blood pressure, stress, exercise, smoking, alcohol use, dental care, and occupational safety and health. Variables from the core questionnaire include height, weight, age, race, sex, Hispanic origin, type of living quarters, region and metropolitan status of residence, marital status, veteran status, education, family income, health status, industry, occupation, activity limitation status, medical conditions, restricted activity days in the past two weeks, bed days in the past two weeks and past 12 months, time interval since the last doctor visit, and the number of doctor visits and short-stay hospital episodes in the past 12 months.

National Health Interview Survey, 1988: Occupational Health Supplement (ICPSR 6047)

Released/updated on: 1993-10-02

Geographic coverage: United States

The basic purpose of the National Health Interview Survey (NHIS) is to obtain information about the amount and distribution of illness, its effects in terms of disability and chronic impairments, and the kinds of health services people receive. Each year, the National Center for Health Statistics conducts the NHIS, a personal interview household survey that uses a nationwide sample of the civilian, noninstitutionalized population of the United States. The NHIS includes a core set of questions that remains virtually unchanged across years on a variety of sociodemographic and health-related concerns. In addition, one or more current health topics is selected for special emphasis annually. For this supplement on occupational health, adult sample persons were asked questions regarding their lifetime working status and their work experience in the year prior to the interview. The primary focus of the supplement was on those individuals who had worked at civilian jobs in the prior year. These persons were asked about work-related injuries, back pain, hand discomfort, skin conditions, eye, nose, and throat irritations, health conditions, and smoking. Those who had previously worked, but not in the prior year, were asked questions about lifetime work experience, and then skipped to the questions on chronic conditions and smoking. Sample persons whose work during the prior year was active military duty also followed this sequence of questions. Those who had never worked were only asked about smoking. This collection also contains data from the basic questionnaire (see NATIONAL HEALTH INTERVIEW SURVEY, 1988 [ICPSR 9412]), including age, sex, race, marital status, education, veteran status, income, family relationship, self-reported health status, and activity limitations, and the number of bed days, doctor visits, and hospital stays in the previous year.

The National Health Interview Survey (NHIS) is conducted annually and sponsored by the National Center for Health Statistics (NCHS), which is part of the U.S. Public Health Service. The purpose of the NHIS is to obtain information about the amount and distribution of illness, its effects in terms of disability and chronic impairments, and the kinds of health services people receive across the United States population through the collection and analysis of data on a broad range of health topics. The redesigned NHIS questionnaire introduced in 1997 (see National Health Interview Survey, 1997 [ICPSR 2954]) consists of a core that remains largely unchanged from year to year, plus an assortment of supplements varying from year to year.

The 2010 NHIS Core consists of three modules: Family, Sample Adult, and Sample Child. The datasets derived from these modules include Household Level, Family Level, Person Level, Injury/Poison Episode Level, Injury/Poison Verbatim Level, Sample Adult Level, and Sample Child level.

The 2010 NHIS supplements consist of stand alone datasets for Cancer Level and Quality of Life data derived from the Sample Adult core and Disability Questions Tests 2010 Level derived from the Family core questionnaire. Additional supplementary questions can be found in the Sample Child dataset on the topics of cancer, immunization, mental health, and mental health services and in the Sample Adult dataset on the topics of epilepsy, immunization, and occupational health.

Part 1, Household Level, contains data on type of living quarters, number of families in the household responding and not responding, and the month and year of the interview for each sampling unit. Parts 2-5 are based on the Family Core questionnaire. Part 2, Family Level, provides information on all family members with respect to family size, family structure, health status, limitation of daily activities, cognitive impairment, health conditions, doctor visits, hospital stays, health care access and utilization, employment, income, participation in government assistance programs, and basic demographic information. Part 3, Person Level, includes information on sex, age, race, marital status, education, family income, major activities, health status, health care costs, activity limits, and employment status. Parts 4 and 5, Injury/Poisoning Episode Level and Injury/Poisoning Verbatim Level, consist of questions about injuries and poisonings that resulted in medical consultations for any family members and contains information about the external cause and nature of the injury or poisoning episode and what the person was doing at the time of the injury or poisoning episode, in addition to the date and place of occurrence.

A randomly-selected adult in each family was interviewed for Part 6, Sample Adult Level, regarding specific health issues, the relation between employment and health, health status, health care and doctor visits, limitation of daily activities, immunizations, and behaviors such as smoking, alcohol consumption, and physical activity. Demographic information, including occupation and industry, also was collected. The respondents to Part 6 also completed Part 7, Cancer Level, which consists of a set of supplemental questions about diet and nutrition, physical activity, tobacco, cancer screening, genetic testing, family history, and survivorship. Part 8, Sample Child Level, provides information from an adult in the household on medical conditions of one child in the household, such as developmental or intellectual disabilities, respiratory problems, seizures, allergies, and use of special equipment like hearing aids, braces, or wheelchairs.

Parts 9 through 13 comprise the additional Supplements and Paradata for the 2010 NHIS. Part 9, Disability Questions Tests 2010 Level, is a supplemental set of six questions asked at the end of the Family Core questionnaire about sensory, mobility, self-care, cognition, and independent living issues. Part 10, Paradata Level, does not contain health related information, but rather data which are related to the interview process, including measures of time, contact-ability, and cooperation. Please see the User Guide for additional information and details. Part 11, Quality of Life Level, was asked to a randomly selected subsection of the Sample Adult questionnaire. Respondents were asked about participation in society, degree of difficulty and functioning in activity domains including vision, hearing, mobility, upper body, learning, cognition, affect, pain, fatigue, and communication. Part 12, Special Sample Adult Disability Weights Level, contains weights for use with an analysis of the merged data from the Sample Adult Level and Disability Questions Tests 2010 Level. Part 13, Sample Child Birth Weights Level, contains corrected birth weight data for 2010. Please see the Survey Description files for additional information and details.
