 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, 178-187, and 337-352 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
                Person Records)

  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.

 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 1995 version, in particular, is found in the Current Estimates
 Series report included with this public use tape documentation.  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 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 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.

 The chronic condition prevalence factor, however, does not incorporate
 the person weight.  It adjusts the sample for distributional
 variations (age, sex, race) within the one-sixth subsample of persons
 who are asked one of six chronic condition lists.  It 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.

 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.  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 decennial census.  Also, the NHIS sample is divided into
 four representative panels to further facilitate linkage to other NCHS
 surveys.  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.
 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.

 It is recommended that users of NHIS data use computer software that
 provides the capability of variance estimation for complex sample
 designs.  The user is referred to the Internet 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 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
 Public Use NHIS database is in preparation.  It will be distributed
 with future releases of this documentation, and will be available from
 the NCHS web site "http://www.cdc.gov/nchswww/nchshome.htm".

 The user should be 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.

 CHANGES IN THE 1995 PUBLIC USE TAPE COMPARED TO 1994

 The 1995 Public Use Tape resembles the 1994 version, with the
 following exceptions.  Most of the modifications occurred because of
 changes to the sampling design.  (Please see section on Sample Design,
 etc. on page 1 of the Introduction). Because of these changes new
 fields have been added while fields that represented the old sampling
 frame have been dropped.  The locations and code differences are
 described below:

 HOUSEHOLD, PERSON, CONDITION, DOCTOR VISIT, AND HOSPITAL RECORD

 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 1995 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.
