National Health Interview Survey (NHIS) is the principal source of information on the
|
|||
|
|
health of the civilian noninstitutionalized population of the United States and is one of the
|
|||
|
|
major data collection programs of the NCHS. The National Health Survey Act of 1956
|
|||
|
|
provided for a continuing survey and special studies to secure accurate and current
|
|||
|
|
statistical information on the amount, distribution, and effects of illness and disability in
|
|||
|
|
the United States and the services rendered for or because of such conditions. The survey
|
|||
|
|
referred to in the Act, now called the National Health Interview Survey, was initiated in July
|
|||
|
|
1957. Since 1960, the survey has been conducted by NCHS, which was formed when the
|
|||
|
|
National Health Survey and the National Vital Statistics Division were combined.
|
|||
|
|
|
|||
|
|
|
|||
|
|
The main objective of the NHIS is to monitor the health of the United States population
|
|||
|
|
through the collection and analysis of data on a broad range of health topics. A major
|
|||
|
|
strength of this survey lies in the ability to categorize these health characteristics by many
|
|||
|
|
demographic and socioeconomic characteristics.
|
|||
|
|
|
|||
|
|
|
|||
|
|
NHIS data are used widely throughout the Department of Health and Human Services
|
|||
|
|
(HHS) to monitor trends in illness and disability and to track progress toward achieving
|
|||
|
|
national health objectives. The data are also used by the public health research
|
|||
|
|
community for epidemiologic and policy analysis of such timely issues as characterizing
|
|||
|
|
those with various health problems, determining barriers to accessing and using
|
|||
|
|
appropriate health care, and evaluating Federal health programs.
|
|||

|||
|
|
|
|||
|
|
Since 1957, the content of the survey has been updated about every 10-15 years to
|
|||
|
|
incorporate advances in survey methodology and coverage of health topics. In January
|
|||
|
|
2019, NHIS launched a redesigned content and structure that differs from the 1997-2018
|
|||
|
|
NHIS.
