 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

         .2     Density = 1600 BPI

         .3     Record length = Fixed length of 360 bytes

         .4     Blocksize = 32760

         .5     Tape format = All fields are in character format

         .6     Data Set Names:

                HOUSEHOLD    = HISY1996.HOUSEHLD

                PERSON       = HISY1996.PERSONSX

                CONDITION    = HISY1996.CONDITON

                HOSPITAL     = HISY1996.HOSPITAL

                DOCTOR VISIT = HISY1996.DRVISITS

      NOTE: Metropolitan Statistical Areas are those defined for the
            1990 Decennial Census.

 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

 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.
