DESCRIPTION: The National Center for Health Statistics (NCHS), in collaboration with the National Institute on Aging (NIA), is conducting the Longitudinal Study of Aging (LSOA). 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. The LSOA is designed to (a) provide mortality rates by demographic, social, economic, and health characteristics that are not available from the vital statistics system, (b) measure change in the functional status and living arrangements of older people, and (c) 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 II is a prospective study with a nationally representative sample comprised of 9,447 civilian noninstitutionalized persons 70 years of age and over at the time of their SOA II interview. The LSOA II followed this cohort of older persons through two follow-up interviews, conducted in 1997-98 and 1999-2000. While the baseline interview was administered face-to-face in the home by U.S. Census Bureau interviewers, follow-up interviews were administered using Computer Assisted Telephone Interviews (CATI) by the National Opinion Research Center at the University of Chicago. Plans are to augment the interview data by linkage to Medicare records, the National Death Index, and multiple cause-of-death records. For more info, see the LSOA II Web Page at NCHS (see below for link).
