Summary: | Conducted by the National Center for Health
Statistics, the Health Interview Surveys (later titled National Health
Interview Survey) first began gathering information as of
1957. Microdata files were permanently retained beginning in 1963. The
surveys obtain information about the amount and distribution of
illness, its effects in terms of disability and chronic impairments,
and the kinds of health services people receive. The series provides a
continuous sampling and interviewing of the civilian,
noninstitutionalized population of the United States through core
surveys and supplemental datasets. Supplemental NHIS data provide
information on topics such as AIDS knowledge and attitudes, child
health care and immunization, dental care, substance abuse,
hospitalization, preventive care, nursing care, prosthetic appliances,
and self-care. Supplements on Aging (SOA) conducted in 1984 and 1994
and the 1984-1990 Longitudinal Study of Aging (LSOA) were designed to
furnish information on the causes and correlates of changes in the
health and functioning of older Americans. Another component of the
NHIS is the National Health Interview Survey on Disability
(NHIS-D). Begun in 1994, the NHIS-D was designed to collect data that
can be used to understand disability and to develop public policy on
disability. Starting in 1997, the NHIS was redesigned to include a
basic module, a periodic module, and a topical module. The basic
module corresponds to the NHIS core questionnaire and is made up of
the family core, the sample adult core, and the sample child core
questions. The periodic module provides more detailed information on
topics resulting from the basic module. The topical modules correspond
to the supplements of the 1982-1996 NHIS and focus on public health
data needs as they arise. |
