National Health Interview Survey, 1994: Second Longitudinal Study on Aging, Wave 3, 2000 (ICPSR 3807)

Principal Investigator(s):


The Second Longitudinal Study of Aging (LSOA II) is a collaborative effort of the National Center for Health Statistics (NCHS) and the National Institute on Aging (NIA). The NATIONAL HEALTH INTERVIEW SURVEY, 1994: SECOND SUPPLEMENT ON AGING (SOA II) (ICPSR 2563) serves as the baseline for this study. LSOA II, Wave 3 consists of 7,936 survivor interviews and 906 decedent interviews in two data files: the Survivor File (Part 1) and the Decedent File (Part 2). The Survivor File contains one record for each sample person (N = 9,447) interviewed at baseline and includes information drawn from several additional sources, including the 1994 National Health Interview Survey (ICPSR 6724) core questionnaire, the 1994 National Health Interview Survey: Family Resources Supplement (ICPSR 2656), Phase I of the 1994 National Health Interview Survey on Disability (ICPSR 2539), and the SOA II baseline interview (ICPSR 2563). Wave 3 questions (beginning at variable SF3664) examined migration, convalescent home utilization, nutrition, influenza immunization, mammogram, prostate, and cholesterol screenings, routine use of vitamins, aspirin, calcium supplements, and antioxidants, and detailed questions on home health care utilization. In addition, a random one-quarter sample of the follow-up respondents were chosen to complete the Childhood Health and Family Longevity Module. This section is similar to that administered during the 1996 Health and Retirement Survey (HRS). Variable SF3462 indicates whether the sample person answered the childhood module. For the Decedent File (Part 2), information was gathered from a family member or close relative regarding sample persons (N = 906) who were deceased at the time of Wave 3 interviews. Questions focused on housing, long-term care, assistance with key activities, chronic conditions, cognitive functioning, health care use, and health insurance.

Restrictions: In preparing the data file for this collection, the National Center for Health Statistics (NCHS) has removed direct identifiers and characteristics that might lead to identification of data subjects.

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.
