Scientific Data Documentation
Core Data, 1996
INTRODUCTION
Since 1957, the National Center for Health Statistics has conducted the
National Health Interview Survey (NHIS) annually. It includes a "core"
set of questions on health-related variables which generally change
little from year-to-year and supplements which can vary annually. In
1982, however, fairly substantial changes were made to parts of the
core. These changes reflect different concepts in the measurement of
health-related variables. Therefore, data derived from these changed
concepts, particularly limitation of activity, acute conditions,
disability days and doctor visits, should not be compared to data
gathered before 1982. A discussion of these changes and the effect on
resulting statistics are contained in the Series 1, No. 18 report and in
a special appendix to the Current Estimates, 1982 (Series 10, No. 150).
More information on the survey in general and the 1996 version, in
particular. The Current Estimates Series report has information about
1996 noninterview rates in the "Source and limitations of data" section.
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.
Sample Size Reduction for 1996
Part of the 1996 NHIS sample was used for testing of the computer
assisted personal interview (CAPI) system that was implemented for the
1997 NHIS. The CAPI test cases are not included in the 1996 Public Use
Tape. Relative to 1995, the 1996 NHIS sample size is reduced by
approximately 25% in the first and second quarters, and by approximately
50% in the third and fourth quarters.
Use of Sample Weights
Since the 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 person record 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.
Each of the six chronic condition lists was administered to a one-sixth
subsample of persons. Hence, the person's basic weight must be
multiplied by the chronic condition prevalence factor to create
prevalence estimates for chronic conditions. Note that the chronic
condition prevalence factor adjusts the sample for distributional
variations (age, sex, race) within the one-sixth subsample of persons.
The chronic condition prevalence factor must be multiplied by the person
weight to create prevalence estimates of chronic conditions. Details
are given in the documentation preceding the condition record tape
layout.
In general, the user should refer to the "Specifications for Recreating
Current Estimates Tables" section for guidance as to the appropriate
weight to use for various analyses.
Imputation
Several variables (age, month of birth, and Hispanic origin) include a
small proportion of imputed values. Imputed values may be identified
using imputation flags that are adjacent to the variables in the Public
Use Tape layout.
Sample Design, Variance Estimation, and Hypothesis Testing
Traditionally, the sampling frame for the NHIS is redesigned every ten
years to better measure the changing U.S. population and to meet new
survey objectives. The fundamental redesign structure of the 1995-2004
NHIS is similar to that of the 1985-1994 NHIS; however, there are two
major changes to the sampling design. First, a state-level
stratification increases the number of primary sampling locations from
the previous value of 198 to a new value of 358. (For confidentiality
reasons, some of the primary sampling locations are collapsed on the
Public Use Tape.) This enhances the capability of using the NHIS for
state estimation and future dual-frame surveys at the state level.
Secondly, both the black and Hispanic populations are oversampled to
allow for more precise estimation of health in these growing minority
populations. In the previous design only black Americans were
oversampled.
Two other important features first implemented in the 1985-1994 design
continue. NCHS survey linkage and followback surveys are facilitated by
an all-area frame with independent address lists which are not based on
the preceding decennial census. Also, the NHIS sample is divided into
four representative panels to further facilitate linkage to other NCHS
surveys. A Series 2 publication containing a description of the survey
design, the methods used in estimation, and general qualifications of
the data obtained from this survey is in preparation.
The data collected in the NHIS are obtained through a complex sample
design involving stratification, clustering, and multistage sampling.
In addition, the weighting factors are subject to adjustments. Because
of this complex design and adjusted sampling weights, the direct
application of standard statistical analysis methods for estimation and
hypothesis testing may yield misleading results. If data are not
weighted, severely biased estimators may result. For this reason, as
indicated previously, it is necessary to use the weights that are
included in the Public Use Tape for analyses.
Weighted data used in standard software packages may provide unbiased
estimators for the typically computed first-order statistics like means
or regression coefficients, but the computed standard errors may be too
small on the average. Also, standard packages may produce hypothesis
test results (such as p values) that are incorrect. Hence, it is
recommended that users of NHIS data use computer software that provides
the capability of variance estimation and hypothesis testing for complex
sample designs. The user is referred to the Internet World Wide Web
site "http://www.fas.harvard.edu/~stats/survey-soft/survey-soft.html"
entitled "Summary of Survey Analysis Software" for current software
information. NCHS uses Taylor series linearization methods, in
particular the SUDAAN software, for NHIS variance estimation. At this
time NCHS does not provide information for use with balanced repeated
replication variance estimation methods. A document providing SUDAAN
code to compute standard errors of means, percentages and totals with
the 1996 Public Use NHIS database is in preparation. It will be
distributed with future releases of this documentation, and will be
available from the NCHS Internet World Wide Web site
"http://www.cdc.gov/nchswww".
The user also is warned that while analyses of large NHIS domains
usually produce reliable estimators with stable variances, the analysis
of small domains may yield unreliable estimators along with unstable
variance estimators. The analyst should pay particular attention to the
estimated coefficient of variation for the estimators of means,
proportions and totals. In addition, small sample sizes, or small
numbers of primary sampling units containing targeted data, may be an
indication of variance estimator instability.

PREFACE
The basic NHIS tape files are created and maintained by Processing
Quarter by Record Type. The contents of these tape files are presented
in the Outline of Items and Codes for each record type. Note that
Household items in tape locations 3-24, 178-186, and 337-358 are repeated
in all records associated with a household; Person items in tape
locations 25-92 are repeated in all records associated with a person.
Users of the tape files should take note of the following tape
characteristics:
1. Type of Record (Tape Locations 1-2)
10 = Household Record - The Household file contains one
household record for each interviewed household and
each Type A non-interviewed household (see Household
locations 28-29).
20 = Person Record - The Person file contains one person
record for each person for whom information was
obtained in an interviewed household.
30 = Condition Record - The Condition file contains one
condition record for each reported condition.
40 = Doctor Visit Record - The Doctor Visit file contains
one record for each reported two-week doctor visit
(includes telephone calls).
50 = Hospital Record - The Hospital file contains one
record for each reported hospitalization (twelve-month
recall).
2. File Sequence
Each file is in sequence by the following identifying items
Tape
Item Location
Household ID 5-14
Person Number
(Blank on Household Record) 15-16
Record Serial Number
(Blank on Household and 17-18
2. File Sequence (Continued)
The household is uniquely identified by the Household ID.
The Person number identifies a person within a household.
Records belonging to a single family within a household can be
identified by using the household identifiers (specified
above) and location 62. Unrelated individuals will have an
"&" or "-" in this location. Persons within a single family
will have the same numeric value from 0-9 in this location on
all family records.
The Record Serial Number identifies multiple records within a
Record Type for a person; for example, condition records for a
person are identified with a unique number beginning with 01
for each condition associated with the person. A person may
have a zero, one, or a multiple number of condition, hospital,
and doctor visit records.
3. Other Tape Characteristics
.1 Headers and trailers = Standard IBM labels

CONDITION FILE INCLUSIONS
The Condition file contains the following types of records:
1. Condition records, either acute or chronic, which are associated
with disability days, doctor visits and/or hospitalizations in
the two weeks preceding the interview (location 107=1 or 2 and
111-112=01-14 or 109=1).
2. Chronic condition records when the condition is reported to be
the main or secondary cause of activity limitation (location
107=1 and 126=1 or 2) or limitation in ability to work.
3. Chronic condition records reported in response to a check list of
conditions for each body system, e.g., digestive. The total
sample was divided into six subsamples. Each subsample was asked
the set of conditions corresponding to one of the six chronic
disease check lists.
Use of Condition Records
NHIS condition records can be used to calculate aggregate estimates and rates
of the incidence of acute conditions (Recode A), prevalence of selected
chronic conditions (Recode C), disability days and utilization associated
with acute or chronic conditions, and chronic conditions causing limitation
of activity. Explanations of the procedures used to calculate these figures
and rates are given below as well as restrictions due to content and
reliability factors.
Included below is a list of special codes in ICD format and tape location
created by NHIS as well as a list of ICD codes not used by NHIS.
NHIS Created Codes
The codes listed below are ICD-like codes with meanings specific to NHIS.
These codes and the Impairment X-codes (see Medical Coding Manual for
complete list of X-codes) are found in the ICD column locations of the
Condition and Doctor Visit Records. The X of the Impairment Codes
(represented by a hyphen '-') is in the first of the four columns.

In addition, the NHIS does not use certain ICD codes, which are conditions
known to be caused by other conditions. In the Ninth Revision of the ICD,
some causal conditions are marked by a dagger and the resulting condition
by an asterisk. NHIS codes the dagger and not the asterisk.
Acute Conditions
Annual incidence estimates can be calculated by the following:
1. Use acute condition records (107:2) and categories from Recode
A (location 100-103).
2. Select those with onset in last two weeks (108:1)
3. Use 6.5 weight (228-236) for all four quarters of data.
Denominators for subdomain rates should be computed by summing the weights
for the entire domain of interest.
When associated disability days such as annual bed days are needed, the
weighted number of bed days in location 246-254 should be substituted for
the 6.5 weight in 3 above).
For additional examples of calculating estimates associated with acute
conditions, see the back of this document.
Chronic Conditions
Recode C is the list of selected chronic conditions for which NHIS
calculates prevalence and associated disability and use data. We feel
that the collection and coding procedures used do not justify any further
breakdown of categories for purposes of estimating prevalence from our
survey. These categories correspond to questions asked on the six chronic
condition lists and therefore produce reliable estimates except where the
numbers are small. In order to obtain NHIS prevalence estimates, use the
Recode C categories following the Tape Layouts.
For chronic conditions not specified in the six lists, estimates do not
reflect prevalence but may be useful in epidemiological investigations.
For most of the non-list conditions only those resulting in limitation of
activity, recent disability days, or doctor visits will be included.
Because chronic conditions-related estimates are made based on a one-sixth
subsample, many estimates, especially for population subgroups, may not be
statistically reliable.
The weights for the six subsamples have been adjusted to the Census
population controls using the same age-sex-race cells as were used for the
entire sample. The most accurate chronic condition aggregate estimates for
population variables other than age, sex and race are achieved by
multiplying rates calculated for the one-sixth subsample by the population
estimate based on the total sample.
For example, to estimate the prevalence of hypertension in the population
with income $25,000+, the rate calculated using the entire circulatory
system subsample and those in the sample with hypertensive disease should
be multiplied times the population estimate from the entire NHIS sample in
the $25,000 income category.
In order to calculate annual prevalence estimates:
1. Use chronic condition records (107:1)
2. Select on the appropriate list number in tape Location 92
3. Select on specified codes in Location 104-106 (Recode C).
4. Multiply the chronic condition prevalence factor (Location 190-
200 divided by 1,000,000,000 to adjust for the implied decimal)
times the annual basic weight in location 219-227.
Rates should be calculated using the population estimates from the
subsample as the denominator. Population estimates from the total sample
also may be used as denominators; however, if rates are to be calculated
for groups other than those defined by age, sex, and race, it may be
preferable to use denominators based on the subsample.
In order to calculate associated disability days, doctor visits, etc., the
specifications above should be used, substituting the appropriate weight
for the basic weight factor in 4. For example, to calculate annual bed
day estimates based on a two-week recall period, use the chronic condition
factor multiplied by the weighted bed days in location 246-254.
Limitation of Activity due to Chronic Condition
To calculate limitation of activity due to chronic conditions on a
condition basis, use the entire NHIS sample, rather than the one-sixth
subsamples. NHIS recommends that Recode B (Location 97-99) be used to
categorize the causal conditions.
Use of Recodes
Recode A - Recode categories for acute conditions. It contains the
smallest categories considered reliable by NHIS for estimating acute
conditions.
Recode B - The recommended recode for limitation of activity. It
corresponds directly to Ninth Revision ICD categories.
Recode C - Recode categories for chronic conditions. It is used by NHIS
for estimating prevalence of chronic conditions.

DIAGNOSTIC RECODE A
Acute Conditions
I. Purpose - Recode A consists of 32 4-digit categories of frequently
reported acute conditions. The NHIS routinely publishes acute
condition incidence estimates and other related acute condition data
using these specific recode categories.
II. Format and Content - The first digit of this 4-digit recode
separates the data into five major condition groups, and the second
digit into subcategories of these five. The third and fourth digits
are the basic units of the recode.
III. Definition of Acute Condition - An acute condition is any disease or
injury with onset in the 3-month reference period prior to the week
of interview except for certain conditions always classified as
chronic regardless of onset. Acute conditions must also have either
activity restriction or medical attention. Current deliveries,
normal or complicated, and current complications of pregnancy and
puerperium are always considered acute conditions. The incidence of
acute conditions is limited to acute conditions with onset in the
2-week reference period prior to the interview week.
This recode is different from Acute Condition Recode 2, used prior to
1982.

DIAGNOSTIC RECODE B
Diseases, Injuries and Impairments
I. Purpose - Recode B is a listing of diseases and injuries
developed by the World Health Assembly (WHA) and modified by the
NHIS to include special impairment codes and residual categories.
This recode, without NHIS modifications, also appears in Volume 1
of the International Classification of Diseases (1975 Revision).
The recode is intended to provide data users with a
classification scheme whereby the NHIS diagnostic categories are
more closely grouped according to the standard International
Classification of Disease groupings. This recode is primarily
used by NHIS to classify conditions reported as causing activity
limitation. For data users interested in producing chronic
condition prevalence estimates, see also Diagnostic Recode C.
II. Format and Content - Recode B is a 3-digit recode that can be
tabulated in two ways. The first 2 digits represent more general
groupings of condition categories and range from 01-57 and 99.
For more detailed condition categories, the complete 3-digit
number - from 010-570 and 990 - is used.
The NHIS has modified this recode in two ways. First, the NHIS
diagnostic coding procedure uses an X-code designation for
impairments instead of an ICD number. For this recode, the X-codes
are reassigned to the recode categories that would have been used
under the ICD scheme. Secondly, residual categories have been added
to accommodate all conditions coded by the NHIS. A code with the
letter "A" following indicates conditions coded by the NHIS only.
This recode is the same as Recode 5 used prior to 1982.

DIAGNOSTIC RECODE C
Chronic Conditions and Impairments
I. Purpose - Recode C consists of 134 3-digit categories of
chronic conditions and impairments. The categories correspond
to the conditions that appear on the six (6) NHIS check-lists
of selected chronic conditions. These categories are used by
NHIS to produce prevalence estimates of selected chronic
conditions.
II. Format and Content - The first digit of this 3-digit recode
identifies the specific chronic condition check-list number,
i.e., 1-6, that corresponds to the number of the list used on
the NHIS questionnaire. The second and third digits are
numbered sequentially within each of the 6 lists. Each
condition group contains between 15 and 43 2-digit categories.
III. Definition of Chronic Condition and Impairment - In most cases,
a chronic condition or an impairment is any departure from
normal health with onset more than 3 months from date of
interview. Certain chronic conditions and impairments are
classified as chronic, however, regardless of date of onset.
Complications of pregnancy are always classified as acute. All
chronic conditions and impairments are counted whether or not
they necessitated activity restriction or medical care.
Impairments coded with an "X" in the first digit are, by
definition, chronic.
This recode is different from Chronic Condition Recode 3, used prior to
1982.

TABULATION SPECIFICATIONS AND WEIGHTING
INTRODUCTION
The tabulation specifications which were used to tabulate
data for the "Current Estimates" report are attached. A
brief description of the key points of each tabulation used
to prepare each table is shown on the attached chart.
The weight for an event occurring or not occurring (binomial
1 or 0) uses the basic weights for the person. Similarly,
if the event has occurred and when it occurs it can have a
frequency of 1, 2, 3, etc.; the weight shown includes the
cross product of the person's basic weight times the
frequency. For instance, if a person is injured and
requires 5 days in bed, the weight shown in the appropriate
table is the person's basic weight times 5.
In most instances in the Health Interview Survey there are
three reference periods used to make estimates: the 2-week
reference period, 6 months, and 12 months. In producing
estimates two types of weights are presented in the tape
records; the basic weight and the 6.5 weight.
The 6.5 weight is a modification of the basic weight
obtained by multiplying the basic weight by 6.5. The figure
6.5 indicates that 2 weeks multiplied by 6.5 represents 13
weeks or one calendar quarter. Summing over 4 calendar
quarters equals 52 weeks. The basic weight for a quarter is
4 times the size of the annual weight (divide basic quarter
weight by 4 to get annual weight).
To illustrate the use of reference periods, suppose we have
a person whose basic weight is 6,000 in the tape for the
quarter. This person's annual weight is 6,000/4 = 1,500.
His 6.5 weight is obtained by multiplying 6,000 x 6.5 to
obtain the 6.5 weight of 39,000. Therefore, if this person
had 2 doctor visits occurring in the 2-week reference
period, his contribution to the annual volume of doctor
visits would have been 39,000 x 2 or 78,000. If he had been
discharged from a hospital once during the 6 months prior to
interview, his contribution to the annual volume of hospital
discharges would be 1,500 x 2 or 3,000 for the full year's
sample, or 6,000 x 2 or 12,000 for a sample of one quarter.
If the reference period was 12 months, the weight for the
year's sample is 1,500 (or 6,000 for the quarterly sample).
The weights are presented in character format in the tape in
Locations 190-236. Where applicable, locations from 237 to
335 contain cross products of variables with frequency
greater than one. For instance, the number of restricted
activity days in the Person Record Locations 98-99 may be 5
days. As a convenience in tabulation, these 5 days have
been multiplied times the appropriate weight (the 6.5 weight
in Locations 228-236) to obtain the weighted estimate of
restricted activity days in Locations 237-245.
A table summarizing these tape locations and their uses follows:

SPECIFICATIONS FOR RECREATING THE CURRENT ESTIMATES TABLES
The accompanying instructions show procedures for deriving estimates from
Health Interview Survey data tapes. The publication, "Current Estimates",
for the year 1996 is used as a source for the examples.
Instructions for inclusions and all appropriate weights are included for
each table specified. In cases where classifications such as "other" may
not be clear or where several fields must be specified to produce a single
variable, for example, persons injured, the variables needed will be
listed.
