title: Version 2

description: The purpose of the National Health Interview Survey (NHIS)
is to 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. Implementation of a
redesigned NHIS, consisting of a basic module, a periodic module, and
a topical module, began in 1997 (See NATIONAL HEALTH INTERVIEW SURVEY,
1997 [ICPSR 2954]). This final release of the 2000 NHIS contains the
Household, Family, Person, Sample Adult, Sample Child, and
Immunization, and Injury and Poison data files from the basic
module. The 2000 NHIS also contains the Cancer Control Module
(included in the Sample Adult File, Part 4), which corresponds to the
Cancer Supplements of 1987 and 1992 and examines such items as diet
and nutrition, use of herbal supplements, Hispanic acculturation,
genetic testing, and family history. Each record in the
Household-Level File (Part 1) of the basic module contains data on the
type of living quarters, number of families in the household
responding and not responding, and the month and year of the interview
for each eligible sampling unit. The Family-Level File (Part 2) is
made up of reconstructed variables from the person-level data of the
basic module and includes information on sex, age, race, marital
status, Hispanic origin, education, veteran status, family income,
family size, major activities, health status, activity limits, and
employment status, along with industry and occupation. As part of the
basic module, the Person-Level File (Part 3) provides information on
all family members with respect to health status, limitation of daily
activities, cognitive impairment, and health conditions. Also included
are data on years at current residence, region variables, height,
weight, bed days, doctor visits, hospital stays, and health care
access and utilization. A randomly-selected adult in each family was
interviewed for the Sample Adult File (Part 4) regarding respiratory
conditions, renal conditions, AIDS, joint symptoms, health status,
limitation of daily activities, and behaviors such as smoking, alcohol
consumption, and physical activity. The Sample Child File (Part 5)
provides information from a knowledgeable adult in the household on
medical conditions of one child in the household, such as respiratory
problems, seizures, allergies, and use of special equipment such as
hearing aids, braces, or wheelchairs. Also included are questions
regarding child behavior, the use of mental health services, and
Attention Deficit Hyperactivity Disorder (ADHD). The Child
Immunization File (Part 6) presents information from shot records and
supplies vaccination status, along with the number and dates of shots,
and information about the chicken pox vaccine. The Injury and Poison
Data File (Part 7) contains episode-level data for injuries and
poisonings and the Injury and Poison Verbatim File (Part 8) contains
verbatim comments for both injuries and poisonings.
description: The NHIS uses a stratified multistage probability design.
 The sample for the NHIS is redesigned every decade using population
 data from the most recent decennial census. A redesigned sample was
 implemented in 1995. This new design includes a greater number of
 primary sampling units (PSUs) (from 198 in 1994 to 358), and a more
 complicated nonresponse adjustment based on household screening and
 oversampling of Black and Hispanic persons, for more reliable
estimates of these groups.

description: The 2000 NHIS data include new race and ethnicity
variables along with changes to the Hispanic origin categories that
reflect the changing composition of the Hispanic population. The race
category of "Asian and Pacific Islander" has now been split into
"Asian" and "Native Hawaiian and Other Pacific Islander." Users should
refer to the codebook for a detailed description of the changes for
the 2000 NHIS.The data from the Household-Level File can be
merged with any of the other files, and other files can be merged as
well. For further information on merging data, consult the
codebook.The periodic module is not yet available from the National Center for Health Statistics (NCHS). When
released, it will provide more detailed information on topics
resulting from the basic module.Per agreement with NCHS, ICPSR
distributes the data files and text of the technical documentation in
this collection in their original form as prepared by NCHS.The
codebooks, data collection instruments, and field representative
manual are provided by ICPSR as Portable Document Format (PDF)
files.
