ABSTRACT
The National Center for Health Statistics has conducted the Health Interview
Survey (NHIS) annually beginning in 1957. It includes a "core" set of
questions on health-related variables which change little from year-to-year
and supplements which can vary annually. More information on the survey in
general is found in the Current Estimates Series report. The NHIS is a
personal interview household survey using a nationwide sample of the
civilian, noninstitutionalized population of the United States. The sample
is chosen in such a way that each person included has a known non-zero
probability of selection. These probabilities of selection along with
adjustments for nonresponse and poststratification are reflected in the
sample weights which are provided on the Public Use Tape.
USE OF SAMPLE WEIGHTS
Since NHIS uses a multistage sample designed to represent the civilian
noninstitutionalized population of the United States, it is necessary to
utilize the person's basic weight for proper analysis of the data. In
addition to the design and ratio adjustments included in the person basic
weight the person weight is further modified depending on the variable
selected (e.g., 2-week bed days), the length of the recall period, and the
period of time for which the estimate is to be made.
For annual prevalence estimates of chronic conditions reported in response
to a condition list, the condition list weight should be used instead of the
person weight. This weight also adjusts for the subsample of persons that
were assigned a given condition list.
SAMPLE DESIGN, VARIANCE, ESTIMATION, AND HYPOTHESIS TESTING
The data collected in the National Health Interview Survey (NHIS) are
obtained through a complex sample design involving both clustering and
stratification. Because of the complex design and the ratio adjustments
applied to the sample weights (see previous section on use of sample
weights), the direct application of standard statistical analysis methods
for variance estimation and hypothesis testing may yield misleading results.
There are computer programs available which provide the capability of
variance estimation for complex sample designs. The balanced repeated
replication approach1 is utilized in &REPERR-&PSALMS-OSIRIS.IV2 to calculate
the variance-covariance matrix. SESUDAAN3 and SURREGR,4 are programs that
calculate the variance-covariance matrix using the linearization approach5
(Taylor series expansion).
In order to provide the user with the capability of estimating the complex
sample variance in the NHIS data using the above procedures, we have
provided Pseudo-Strata and Pseudo Primary Sampling Unit (PSU) codes on the
data tapes. These variables and the sample weights are necessary for the
calculation of variances.
Even though the overall number of persons in this survey is quite large for
statistical inference purposes, subclass analyses can lead to estimators
that are unreliable. Consequently, analyses of subclasses require that the
user pay particular attention to the coefficient of variation for the
estimates of means, proportions and totals. In addition, small sample
sizes, or a small number of PSU's used in the variance calculations may
produce unstable estimates of the variances using the above computer
programs.
A NCHS Series 2 publication discussing these issues is in publication.
Detailed information from this publication on calculating variances and the
use of sample weights is available, upon request, from NCHS.
SELECTION CRITERIA
(a) Age greater than or equal to 30 (at the time of interview).
(b) Variables of specific substantive interest (e.g., ethnicity).
(c) Information on a given variable being available for at least 8 years.
(d) Variable selected only once, though parallel entries exist on the input
files that were merged.
(e) Variables that related only to data processing and collection such as
interview number, etc., were excluded.
(f) Conditions that were defined as chronic by NCHS and caused limitation
of activity either as the primary cause or as a secondary cause.

APPENDIX F - CONDITION LISTS
Condition Lists
Methodological studies, which had been conducted since the beginning of
the survey, showed that chronic conditions are generally under-reported in
interviews. They also indicated that the expansion of a checklist of
chronic conditions to include as many descriptive titles as possible will
increase the probability of a person reporting a condition, assuming that he
is aware of its existence. These findings led to the decision to restrict
the collection of prevalence data on chronic conditions to specific types of
conditions during a given collection year.
Concentrating on a group of chronic conditions involving a specific
system of the body (e.g., those affecting the digestive system) rather than
on the entire spectrum of chronic conditions not only improve the quality of
response but also permits the collection of more detailed diagnostic
information related to that body system. See Appendix I. The survey plan
calls for the collection of different types of conditions each year, so that
within 5 or 6 years after the initiation of this plan, information on the
prevalence of virtually all chronic conditions will have been obtained.
For purposes of making prevalence estimates of chronic conditions, a
list of conditions is read to the respondent. For each condition reported,
detailed questions are asked. From 1968-77 the following six lists of
conditions were used (one per year except in 1974 when no list was used):
* Conditions of the musculoskeletal system and skin: 1969, 1976.
* Conditions of the respiratory system: 1970.
* Impairments: 1971, 1977.
* Conditions of the cardiovascular system: 1972.
* Conditions affecting the nervous system, glandular disorders, and
conditions of the genitourinary system: 1973.
* Conditions of the digestive system: 1968, 1975.
Starting in 1978 and continuing through 1983 a major change in interview
procedures was made in which all six of the lists of conditions were
included on the questionnaire. However, any specific household was asked
only one list.
APPENDIX G - DEFINITIONS OF CERTAIN TERMS USED IN NHIS
Terms Relating to Conditions
Definitions Of Certain Terms Used In The Health Interview Survey
Condition. A morbidity condition, or simply a condition, is any entry
on the questionnaire that describes a departure from a state of physical or
mental well-being. It results from a positive response to one of a series
of "medical-disability impact" or "illness-recall" questions. In the coding
and tabulating process conditions are selected or classified according to a
number of different criteria such as whether they were medically attended,
whether they resulted in disability, or whether they were acute or chronic;
or according to the type of disease, injury, impairment, or symptom
reported. For the purposes of each published report or set of tables, only
those conditions recorded on the questionnaire that satisfy certain stated
criteria are included.
Conditions except impairments are classified by type according to the
Eighth and Ninth Revision of the International Classification of Diseases,
Adapted for Use in the United States, with certain modifications adopted to
make the code more suitable for a household interview survey.
Acute Condition. An acute condition is defined as a condition that has
lasted less than 3 months and that has involved either medical attention or
restricted activity. Because of the procedures used to estimate incidence,
the acute conditions included in this report are the conditions that had
their onset during the 2 weeks prior to the interview week and that involved
either medical attention or restricted activity during that 2-week period.
However, certain conditions are always classified as chronic regardless of
onset (see list under the definition of chronic condition).
Acute Condition Groups. In this report all tables that have data
classified by types of condition employ a five-category regrouping plus
several selected subgroups.
Chronic Condition. A condition is considered chronic if (1) the
condition is described by the respondent as having been first noticed more
than 3 months before the week of the interview of (2) it is one of the
conditions listed below that are always considered chronic regardless of the
date of onset.
Allergy, any
Arthritis or rheumatism
Asthma
Cancer
Cleft Palate
Club foot
Condition present since birth
Deafness or serious trouble with hearing
Diabetes
Epilepsy
Hardening of the arteries
Hay fever
Heart trouble
Hemorrhoids or piles
Hernia or rupture
High blood pressure
Kidney stones
Mental illness
Missing fingers, hand, or arm-toes, foot, or leg
Palsy
Paralysis of any kind
Permanent stiffness or deformity of the foot, leg, fingers, arm, or back
Prostate trouble
Repeated trouble with back or spine
Rheumatic fever
Serious trouble with seeing, even when wearing glasses
Sinus trouble, repeated attacks of
Speech defect, any
Stomach ulcer
Stroke
Thyroid trouble or goiter
Tuberculosis
Tumor, cyst, or growth
Varicose veins, trouble with
Prevalence of Conditions. In general, prevalence of conditions is the
estimated number of conditions of a specified type existing at a specific
time or the average number existing during a specified internal of time.
The prevalence of chronic conditions is defined as the number of chronic
cases reported to be present or assumed to be present at the time of the
interview. Those assumed to be present at the time of the interview are
cases described by the respondent in terms of one of the diseases on the
list of conditions always considered chronic (see definition of chronic
condition above) and reported to have been present at some time during the
12-month period prior to the interview.
Incidence of Conditions. The incidence of conditions is the estimated
number of conditions having their onset in a specified time period. As
previously mentioned, minor acute conditions involving neither restricted
activity nor medical attention are excluded from the statistics. The
incidence data shown in some reports are further limited to various
subclasses of conditions, such as "incidence of conditions involving bed
disability."
Onset of Condition. A condition is considered to have had its onset
when it was first noticed. This could be the time the person first felt
sick or became injured, or it could be the time when the person or his
family was first told by a physician that he had a condition of which he was
previously unaware.
Persons With Chronic Conditions. The estiated number of persons with
chronic conditions is based on the number of persons who at the time of the
interview were reported to have one or more chronic conditions.
Activity-Restricting Condition. An activity-restricting condition is
one that had its onset in the past 2 weeks and that caused at least 1 day of
restricted activity during the 2 calendar weeks before the interview week.
(See "Restricted-activity day" under "Terms Relating to Disability.")
Bed-Disabling Condition. A condition with onset in the past 2 weeks
involving at least 1 day of bed disability is called a bed-disabling
condition. (See "Bed-disability day" under "Terms Relating to Disability.")
Medically Attended Condition. A condition with onset in the past 2
weeks is considered medically attended if a physician has been consulted
about it either at its onset or at any time thereafter. However, when the
first medical attention for a condition does not occur until after the end
of the 2-week period, the case is treated as though there was not medical
attention. Medical attention includes consultation either in person or by
telephone for treatment or advice. Advice from the physician transmitted to
the patient through the nurse is counted as well as visits to physicians in
clinics or hospitals. If during the course of a single visit the physician
is consulted about more than one condition for each of several patients,
each condition of each patient is counted as medically attended.
Discussions of a child's condition by the physician and a responsible
member of the household are considered as medical attention even if the
child was not seen at that time.
For the purpose of this definition, the term "physician" includes
doctors of medicine and osteopathic physicians.
Terms Relating to Disability
Disability. Disability is the general term used to describe any
temporary or long-term reduction of a person's activity as a result of an
acute or chronic condition.
Disability Day. Short-term disability days are classified according to
whether they are days of restricted activity, bed days, hospital days,
work-loss days, or school-loss days. All hospital days are, by definition,
days of bed disability; all days of bed disability are, by definition, days
of restricted activity. The converse form of these statements is, of
course, not true. Days lost from work and days lost from school are special
terms that apply to the working and school-age populations only, but these
too are days of restricted activity. Hence, "days of restricted activity"
is the most inclusive term used to describe disability days.
Restricted-Activity Day. A day of restricted activity is one on which a
person cuts down on his usual activities for the whole of that day because
of an illness or an injury. The term "usual activities" for any day means
the things that the person would ordinarily do on that day. For children
under school age, usual activities depend on whatever the usual pattern is
for the child's day, which will in turn be affected by the age of the child,
weather conditions, and so forth. For retired or elderly persons, usual
activities might consist of almost no activity, but cutting down on even a
small amount for as much as a day would consititute restricted activity. On
Sundays or holidays, usual activities are the things the person usually does
on such days--going to church, playing golf, visiting friends or relatives,
or staying at home and listening to the radio, reading, watching television,
and so forth. Persons who have permanently reduced their usual activities
because of a chronic condition might not report any restricted--activity
days during a 2-week period. Therefore, absence of restricted-activity days
does not imply normal health.
Restricted activity does not imply complete inactivity, but it does imly
only the minimum of usual activities. A special nap for an hour after lunch
does not constitute cutting down on usual activities, nor does the
elimination of a heavy chore such as cleaning ashes out of the furnace or
hanging out the wash. If a farmer or housewife carried on only the minimum
of the day's chores, however, this is a day of restricted activity.
A day spend in bed or a day home from work or school because of illness
or injury is, of course, a restricted-activity day.
Bed-Disability Day. A day of bed disability is one on which a person
stays in bed for all or most of the day because of a specific illness or
injury. All or most of the day is defined as more than half of the daylight
hours. All hospital days for inpatients are considered to be days of bed
disability even if the patient was not actually in bed at the hospital.
Work-Loss Day. A day lost from work is a day on which a person did not
work at his job or business for at least half of his normal workday because
of a specific illness or injury. The number of days lost from work is
determined only for persons 17 years of age and over who reported that at
any time during the 2-week period covered by the interview they either
worked at or had a job or business. (See "Currently employed persons" under
"Demographic Terms.")
School-Loss Day. A day lost from school is a normal school day on which
a child did not attend school because of a specific illness or injury. The
number of days lost from school is determined only for children 6-16 years
of age.
Person-Day. Person-days of restricted activity, bed disability, and so
forth are days of the various forms of disability experienced by any one
person. The sum of days for all persons in a group represents an
unduplicated count of all days of disability for the group.
Condition-Day. Condition-days of restricted activity, bed disability,
and so forth are days of the various forms of disability associated with any
one condition. Since any particular day of disability may be associated
with more than one condition, the sum of days for conditions may add to more
than the total number of person-days.
Chronic Activity Limitation
Persons are classified into four categories according to the extent to which
their activities are limited at present as a result of chronic conditions.
Since the usual activities of preschool children, school-age children,
housewives, and workers and other persons differ, a different set of criteria
is used for each group. There is a general similarity between them, however,
as will be seen in the following descriptions of the four categories:
1. Persons unable to carry on major activity for their group (major
activity refers to ability to work, keep house, or engage in school or
preschool activities).
Preschool children:
Inability to take part in ordinary play with other children.
School age children:
Inability to go to school.
Housewives:
Inability to do any housework.
Workers and all other persons:
Inability to work at a job or business.
2. Persons limited in amount or kind of major activity performed (major
activity refers to ability to work, keep house, or engage in school or
preschool activities).
Preschool children:
Limited in amount or kind of play with other children, e.g., need
special rest periods, cannot play strenuous games, or cannot play for
long periods at a time.
School-age children:
Limited to certain types of schools or in school attendance, e.g.,
need special schools or special teaching or cannot go to school
full-time or for long periods at a time.
Housewives:
Limited in amount or kind of housework, e.g., cannot lift children,
wash or iron, or do housework for long periods at a time.
Workers and all other persons:

APPENDIX H - NOTE RE CHANGE IN ICD CODES
A major change made in 1979 affects the comparison of 1979, 1980, and
1981 illness data with data from earlier years. Beginning in 1979,
illnesses and injuries were coded using the ninth revision of the
International Classification of Diseases rather than the eighth revision
used in 1978 and earlier years mentioned in the report. Caution should
therefore be used when comparing data in specific disease categories.
Detailed information on the old and new disease category classification is
available from the Interview and Examination Statistics Program of the
National Center for Health Statistics.
APPENDIX I - Changes in questions regarding limitations
With the introduction of restricting the collection of information on
chronic conditions to those affecting a specific system (beginning in July
1967), it was felt that the amount of data relating to the history,
treatment, and development of such conditions should be increased. Since
the new "person approach" called for the collection of information on
activity and mobility limitation on a person basis, the questions relating
to limitation were transferred to another area on the questionnaire, and
detailed information on specific chronic conditions was obtained by adding a
section identified as AA to each condition page. Section AA was revised to
some extent during the trial period (July 1967 - December 1968) and has
remained as an integral part of the condition page through calendar year
1981 (see below).
AA Continue for conditions listed or reported in probe question 31,
otherwise go to A5. For missing extremities or organs, go to A5.
