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. 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.

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

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

Investigators: National Center for Health Statistics

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.

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.

National Household Survey on Drug Abuse, 1990

Investigators: Joseph Gfroerer, Joseph Gustin, Thomas Virag, Ralph Folsom & J. Valley Rachal

The 1990 National Household Survey on Drug Abuse (NHSDA) is the tenth in a series of cross-sectional studies, which began in 1971, designed to measure the prevalence and correlates of drug use in the United States household population aged 12 and over. The 1990 NHSDA was sponsored by the National Institute of Drug Abuse (NIDA). Researchers from the Research Triangle Institute in Research Triangle Park, North Carolina, directed the 1990 study. The basic sample design involved several selection stages; these were the selection of Primary Sampling Units (PSUs, e.g. counties), area segments (e.g., blocks or enumeration districts) within these PSUs, sample households within area segments, one or two (if any) age group domains within sample households, and a person within selected age group domains. Interviewers administered questionnaires in-person. All samples were done using probability methods. Topics covered in the 1990 NHSDA include tobacco, alcohol, and illicit drug use; consequences of various drugs; health condition; and general demographic information.

National Household Survey on Drug Abuse, 1991

Investigators: Joseph Gfroerer, Joseph Gustin, Thomas Virag, Ralph Folsom & J. Valley Rachal

The NHSDA is the only study that produces estimates of drug use among members of the household population the United States. The survey is appropriate for estimating prevalence rates for different drugs, since much drug use would not ordinarily come to the attention of administrative, medical, or correctional authorities and therefore would not be included in official statistics. In-person interviews with a large national probability sample seem to be the best way to estimate drug use in virtually the entire population of the United States. Topics covered in the 1991 NHSDA include tobacco, alcohol, and illicit drug use; consequences of various drugs; health condition; treatment for drug use; illegal activities; and use of anabolic steroids. Also, sets of questions regarding insurance and personal and family income sources and amounts were expanded in comparison to previous surveys. The 1991 survey includes 1,283 variables. The content of the NHSDA changes slightly from year to year. Changes made over the course of the 1990 and 1991 surveys include changes regarding sampling methods, sample populations, and the deletion and addition of variables. The 1991 NHSDA is the first NHSDA to sample from Alaska and Hawaii in addition to the contiguous states. Furthermore, unlike previous surveys, residents of non-institutional group quarters (e.g., college dormitories, group homes, civilians dwelling on military installations) and persons with no permanent residence (homeless people and residents of single rooms in hotels) were sampled in the 1991 NHSDA.

National Long Term Care Survey: 1982, 1984, 1989

Investigators: Center for Demographic Studies United States Department of Health and Human Services Health Care Financing Administration

The National Long Term Care Survey is a longitudinal study designed to provide information about the population of chronically disabled elderly persons in the United States. It was the first major nationally representative survey that dealt explicitly with the health and functional problems of the disabled elderly who live in the community, the formal and informal home long term care options available to meet the problems of the impaired elderly, and the ability to interchange home and institutional services for a specific population. The first three waves of interviews (1982, 1984, and 1989) were conducted with nationally representative sample of 30,308 persons age 65 or over who reported having a chronic functional impairment, defined as being unable to perform an activity of daily living (ADL) or an instrumental activity of daily living (IADL) for three months or more. Data were collected on a number of topics including cognitive ability, medical conditions, problems and help received for ADLs and IADLs, housing, health insurance, medical providers, income and assets, and personal characteristics. In addition, the 1989 wave collected extensive data from informal caregivers, unpaid caregivers who help the sample person with ADL or IADL activities. Topics covered in the survey of informal caregivers included demographic and social characteristics of the caregiver, the relationship between the caregiver and the impaired person, the kinds of care provided, expense and time costs to the caregiver, inconveniences and problems of the caregiver, work restrictions due to caregiving, and the caregivers feeling about caregiving.
