Abstract: The Longitudinal Study of Aging (LSOA), conducted by the National Center for Health Statistics (NCHS) in collaboration with the National Institute on Aging (NIA), is designed to (1) provide mortality rates by demographic, social, economic, and health characteristics that are not available from the vital statistics system, (2) measure change in the functional status and living arrangements of older people, and (3) provide measures of health care use. It is also designed to describe the continuum from functionally independent living in the community through dependence, possible institutionalization, and finally death. The LSOA is an extension of the National Health Interview Survey (NHIS) of 1984, following its sample of 16,148 noninstitutionalized elderly people (55 years and over) living in the United States, with a special focus on those who were 70 years and over in 1984. This release of the LSOA contains data on those respondents who had been 70 years and older at the time of their 1984 interviews. The data include 1986, 1988, and 1990 reinterviews, National Death Index matches from 1984-1989, and 1987 interviews with contact persons named by decedents, as well as selected variables from the 1984 NHIS core questionnaire and its two supplements, Health Insurance and the Supplement on Aging (SOA). Two Medicare files are included for 1984-1990: Hospital Records, and Other Medicare Use (Indicators of Home Health Care, Hospice, and Outpatient Use ). Links also are provided to allow merging of additional variables from the NATIONAL HEALTH INTERVIEW SURVEY, 1984 (ICPSR 8659).

SOURCE: personal interviews, computer-assisted telephone interview (CATI) plus follow-up mail questionnaire where necessary, National Death Index records from the National Center for Health Statistics, and Medicare Automated Data Retrieval System (MADRS) records from the Health Care Financing Administration

UNIVERSE: Persons who in 1984 were 70 years and older and living in the community.

SAMPLE: The sample for the LSOA was drawn in stages. First, in 1984, all SOA households with a person aged 80 or over (''oldest old'') were selected. Within these households, all persons aged 80 or over and their relatives aged 70-79 were selected. Second, all other households with a person aged 70-79 were selected. From these households, all Black persons and their relatives aged 70-79 were selected. Finally, the remaining households with a person aged 70-79, whose residents were all either white or other non-Black persons, were randomly sorted, and one-half of the households were selected for the sample. If more than one person aged 70-79 resided in a household that was selected, all were included. The 1986 sample was reduced in size, but 1988 and 1990 data collection expanded to trace all the original respondents 70 years and older.

NOTE: Per agreement with NCHS, ICPSR distributes the data file(s) and technical documentation for this collection in their original form as prepared by NCHS. The age distribution of the sample of 7,527 persons in 1984 was: ages 70-74 (N = 3,131), 75-79 (N = 2,306), 80-84 (N = 1,266), and 85-99 (N = 824).

EXTENT OF COLLECTION: 3 data files + machine-readable documentation (text) + data collection instrument.

RESTRICTIONS: In preparing the data tape(s) for this collection, the National Center for Health Statistics (NCHS) has removed direct identifiers and characteristics that might lead to identification of data subjects. As an additional precaution, NCHS requires, under section 308(d) of the Public Health Service Act (42 U.S.C. 242m), that data collected by NCHS not be used for any purpose other than statistical analysis and reporting. NCHS further requires that analysts not use the data to learn the identity of any persons or establishments and that the director of NCHS be notified if any identities are inadvertently discovered. ICPSR member institutions and other users ordering data from ICPSR are expected to adhere to these restrictions.
