National Health Interview Survey (NHIS) 2015

Investigators: Centers for Disease Control and Prevention (CDC)

The National Health Interview Survey (NHIS) is the principal source of information on the health of the civilian noninstitutionalized population of the United States and is one of the major data collection programs of the National Center for Health Statistics (NCHS). The main objective of the NHIS is to monitor the health of the United States population through the collection and analysis of data on a broad range of health topics. A major strength of this survey lies in the ability to categorize these health characteristics by many demographic and socioeconomic characteristics. NHIS data are used widely throughout the Department of Health and Human Services (HHS) to monitor trends in illness and disability and to track progress toward achieving national health objectives. The data are also used by the public health research community for epidemiologic and policy analysis of such timely issues as characterizing those with various health problems, determining barriers to accessing and using appropriate health care, and evaluating Federal health programs. The NHIS questionnaire consists of two parts: (1) a set of basic health and demographic items (known as the Core questionnaire), and (2) Supplements. The Core questions remain largely unchanged from year to year and allow for trends analysis and for data from more than one year to be pooled to increase sample size for analytic purposes. The Core contains four major components: Household, Family, Sample Adult, and Sample Child. The Household component collects limited demographic information on all of the individuals living in a particular house. The Family component verifies and collects additional demographic information on each member from each family in the house and collects data on topics including health status and limitations, injuries, healthcare access and utilization, health insurance, and income and assets. The Family Core component allows the NHIS to serve as a sampling frame for additional integrated surveys as needed. From each family in the NHIS, one sample adult and one sample child (if any children are present) are randomly selected and information on each is collected with the Sample Adult Core and the Sample Child Core questionnaires. Because some health issues are different for children and adults, these two questionnaires differ in some items but both collect basic information on health status, health care services, and health behaviors.

National Health Interview Survey on Child Health, 1988

Investigators: National Center for Health Statistics

The 1988 National Health Interview Survey on Child Health (NHIS-CH) was conducted by the National Center for Health Statistics (NCHS), and cosponsored by the National Institute for Child Health and Human Development and the Health Resources and Services Administration. The U. S. Census Bureau directed field work for the survey. The National Health Interview Survey (NHIS) is a continuous, cross-sectional survey representing the household population of the United States. Each year the NHIS collects basic health and demographic information by face-to-face interview with a sample of about 122,000 family members in about 47,000 families. Typically, different households are sampled each year. For the 1988 NHIS-CH, additional information was collected for one randomly selected child 0-17 years of age in each NHIS sample household. Topics covered in the 1988 NHIS-CH interview included child care, marital history of the child's parents, geographic mobility, circumstances of the pregnancy and birth, injuries, impairments, acute conditions, chronic conditions, passive smoking, sleep habits, school problems, developmental problems, and use of health care services. Some of the same topics were included in the 1981 NHIS on child health, permitting trend analyses. Other special health topic questionnaires administered in 1988 resulted in public use data files that can be linked to the NHIS-CH. Those topics included alcohol use and occupational health, both asked of a sample adult in the family. Those data sets are available from NCHS. It should be noted that the health characteristics described by NHIS estimates pertain only to the resident, civilian non-institutionalized population of the United States living at the time of the interview. The sample does not include persons residing in nursing homes, members of the armed forces, institutionalized persons, or U.S. nationals living abroad

The 1988 National Health Interview Survey on Child Health (NHIS-CH) was conducted by the National Center for Health Statistics (NCHS), and cosponsored by the National Institute for Child Health and Human Development and the Health Resources and Services Administration. The U.S. Census Bureau directed field work for the survey. Every year the National Health Interview Survey (NHIS) asks a standard set of health and demographic questions about each member of sample families; in addition, one or more questionnaires on special health topics may be administered to one or more selected family members. For 1988, the NHIS focussed on the child and the supplemental section consisted of the Child Health Supplement. In addition to the Child Health Supplement the questionnaire contained items on demographic and health information for other individuals within the sample child's household. Topics covered in the 1988 NHIS-CH interview included child care, marital history of the child's parents, geographic mobility, circumstances of the pregnancy and birth, injuries, impairments, acute conditions, chronic conditions, passive smoking, sleep habits, school problems, developmental problems, and use of health care services. The resulting data set for this survey includes 1347 variables and 17,110 cases.

National Health Interview Survey on Disability, Complete Phase I, 1994-1995

Investigators: National Center for Health Statistics

Since 1957, the National Center for Health Statistics (NCHS) annually conducts a National Health Interview Survey (NHIS), which consists of a core questionnaire and supplements. The core questionnaire is aimed at a continuous assessment and analysis of health trends in the United States, and its topics--basic health, socioeconomic, and demographic data--do not vary much across years. Each year, one or more supplements are added to this core questionnaire to reflect public health data needs. Recent supplement topics included cancer risk factors, youth risk behaviors, knowledge and attitudes about AIDS, and child health. The 1994-1995 National Health Interview Survey on Disability (NHIS-D) was one of the supplements to the 1994 and 1995 NHIS core questionnaires. Due to the low prevalence of disabilities among noninstitutionalized civilians, the NHIS-D was collected over two years, from January 1994 to December 1995. The NHIS-D was designed to meet the need for data on the prevalence and nature of disability in the U.S. since the establishment of the Americans with Disabilities Act (ADA) in 1990. One of the main objectives of the NHIS-D was to develop a survey instrument that would provide useful disability measures while accommodating social, administrative, and medical considerations, so that the data could be analyzed by a variety of agencies and programs. Also, the NHIS-D was designed to collect data to facilitate public health policy and provide descriptive baseline statistics on the effects of disabilities. The NHIS-D, Phase I questionnaire was administered at the same time as the NHIS core questionnaire and the other supplements. Given the limited amount of time allocated for the disability supplement, the NCHS decided to conduct a two-phase data collection with two separate questionnaires on disability. Eligibility for the NHIS-D, Phase II was based on the responses to the Phase I disability supplement, as well as the core questionnaire topics on activity limitation, and the family resource supplement regarding the receipt of disability benefits. The Phase II survey began in August 1994 with sample numbers of 20,410 in 1994 and 12,378 in 1995, and it was completed in 1997. This follow-up survey data on disability (1994-1995 NHIS-D, Phase II) will be archived in RADIUS during fall of 1998 and will include ID variables for linking Phase I and II datasets. The sample size for Phase I is 202,560 (107,469 in 1994 and 95,091 in 1995). The decrease in sample size for the 1995 survey reflects a change in the sample design as well as the federal government furlough, which reduced the time for data collection.

National Health Interview Survey on Disability, Complete Phase II, 1994-1995

Since 1957, the National Center for Health Statistics (NCHS) annually conducts a National Health Interview Survey (NHIS) of the U.S. noninstitutionalized civilian population, which consists of approximately 122,000 individuals in 48,000 households. The NHIS consists of a core questionnaire and supplements. The core questionnaire is aimed at a continuous assessment and analysis of health trends in the United States, and its topics--including basic health, socioeconomic, and demographic data--do not vary much across years. Each year, one or more supplements are added to this core questionnaire to reflect public health data needs.

The NHIS-D, Phase I questionnaire was administered at the same time as the NHIS core questionnaire and the other supplements. Given the limited amount of time allocated for the disability supplement, the NCHS decided to conduct a two-phase data collection with two separate questionnaires on disability. Eligibility for the NHIS-D, Phase II was based on the responses to the Phase I disability supplement, as well as the core questionnaire topics on activity limitation, and the family resource supplement regarding the receipt of disability benefits. The complete--merged 1994/95--NHIS-D Phase I data and documentation are available as RADIUS dataset 35-36. The Phase II interviews were conducted six to eight months after the Phase I interviews, beginning in August 1994 and ending in 1997. Interviews using the Adult questionnaire were conducted with the individual identified from the Phase I interview whenever possible. The respondent for the Child component was the parent or the adult in the household who knew the most about the child's health. The NHIS-D, Phase II Child survey includes information on utilization and the need for services, functional assessment, and the impact of the child's disability on the family. The 1994 and 1995 Child surveys were merged and archived by RADIUS staff as Dataset 37-38. Dataset 37-38 contains 1,199 variables and 6,983 cases. The Adult questionnaire obtained extensive information on issues such as employment, transportation needs, personal assistance needs, use of services and benefits, and participation in social activities. The 1994 and 1995 Adult surveys were merged and archived by RADIUS staff as Dataset 39-41. Dataset 39-41 contains 2,534 variables and 25,805 cases. An additional Outcome file, archived as RADIUS Dataset 42, provides information on the response or non-response of Phase I respondents eligible for either the Adult or Child phase II. Dataset 42 contains 4 variables and 202,560 cases. Identification variables are available to link NHIS-D respondents between Phases (I/II) as well as within households (Child/Adult), and to related government-sponsored data collections.

National Health Interview Survey, Sample Adults, 2000

Investigators: National Center for Health Statistics

The National Health Interview Survey (NHIS) is a multi-purpose health survey conducted annually by the National Center for Health Statistics (NCHS) and is the principal source of information on the health of the civilian, noninstitutionalized, household population of the United States. The NHIS has been conducted continuously since its beginning in 1957. The main objective of the NHIS is to monitor the health of the United States population through the collection and analysis of data on a broad range of health topics. A major strength of this survey lies in the ability to display these health characteristics by many demographic and socioeconomic characteristics. NHIS data are used widely throughout the Department of Health and Human Services (DHHS) to monitor trends in illness and disability and to track progress toward achieving national health objectives. The data are also used by the public health research community for epidemiologic and policy analysis of such timely issues as characterizing those with various health problems, determining barriers to accessing and using appropriate health care, and evaluating Federal health programs. The data set archived by Sociometrics contains data from three components or modules of the 2000 NHIS: the family core, the sample adult core, and the cancer control module. The family core component collects information on everyone in the respondent's family, including information on household composition and socio-demographic characteristics, basic indicators of health status, activity limitations, injuries, health insurance coverage, and access to and utilization of health care services. Within each family in the NHIS, one sample adult is randomly selected, and is administered the sample adult core questionnaire. For each sample adult, extensive information is collected on health status, conditions, disability, health care services, and behavior. In addition, sample adults were administered the cancer control module, which focused on cancer risk factors and behaviors and collected information on Hispanic acculturation, diet and nutrition, physical activity, tobacco, cancer screening, genetic testing, and family history.

National Health and Social Life Survey, 1992

Investigators: Edward O. Laumann, Robert T. Michaels, John H. Gagnon, & Stuart Michaels

The 1992 National Health and Social Life Survey (NHSLS) is the most comprehensive representative survey to date of sexual behavior in the United States general population. Conducted by a research team centered at the University of Chicago, the NHSLS was designed not only to determine the prevalence of various sexual practices, but also to examine the social and psychological contexts in which those practices occur. The NHSLS dataset contains information on 1,604 variables gathered from interviews with a national probability sample of 3,432 American men and women between the ages of 18 and 59. The study explores the extent to which sexual conduct and general attitudes toward sexuality are influenced by gender, age, marital status, and other demographic characteristics. Among the numerous topics covered by the NHSLS are early sexual experiences, masturbation, contraception and fertility, sexual abuse, coercion, sexual health, satisfaction, sexual fantasy, sexual dysfunction and homosexuality. Demographic information was collected on race, religious affiliation, education, and income.
