Summary View help for Summary
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 (ICPSR 2563), serves as the baseline for this study. LSOA II Wave 2 interviews were conducted with a total of 7,998 respondents who were interviewed at baseline and consists of 7,060 survivor interviews and 998 decedent interviews. LSOA II Wave 2 is comprised of two data files, the Survivor Data (Part 1) and the Decedent Data (Part 2). The Survivor Data contains one record for each sample person (N = 9,447) interviewed at baseline and includes information drawn from several additional sources, including NATIONAL HEALTH INTERVIEW SURVEY, 1994 (ICPSR 6724) core questionnaire, NATIONAL HEALTH INTERVIEW SURVEY, 1994: FAMILY RESOURCES INCOME AND ASSETS SUPPLEMENT (ICPSR 2656), and NATIONAL HEALTH INTERVIEW SURVEY ON DISABILITY, 1994: PHASE I, DISABILITY OUTCOME SUPPLEMENT (ICPSR 2539). Wave 2 questions examined migration, convalescent home utilization, persistent symptomatic conditions such as pain in legs, swelling in feet, etc., nutrition, influenza immunization, mammogram, prostate, and cholesterol screenings, routine use of vitamins and aspirin, 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 Data (Part 2) information was gathered from a family member or close relative regarding sample persons (N = 938) who were deceased at the time of Wave 2 interviews. Questions focused on housing, long-term care, assistance with key activities, chronic conditions, cognitive functioning, and health care use and health insurance.

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. 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.
