Summary: |
This study, commonly known as the Longitudinal Study of
Aging (LSOA), was conducted by the National Center for Health
Statistics (NCHS) in collaboration with the National Institute on
Aging (NIA) and 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 was 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
also included: Part 2, Medicare Hospital Records, and Part 3, Other
Medicare Use Records (which covers 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).

Data Collection Notes: |
The current release of this collection is NCHS's
Version 5 of the LSOA.
The codebooks with frequencies, data
collection instrument, and new record layouts for Version 5 of the
LSOA are provided as a Portable Document Format (PDF) file.
Per
agreement with NCHS, ICPSR distributes the data file(s) and text of
the 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).

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 person 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.

Data 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
|
Extent of Processing: |
All archived data undergo a confidentiality review and are altered when necessary to limit the risk of
disclosure. The archive also routinely creates ready-to-go data files along with setups in the major
statistical software formats as well as standard codebooks to accompany the data. In addition to
these procedures, the archive performed the following processing steps for this data collection:
-
Created online analysis version with question text.

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.
