 PREFACE

     The basic NHIS tape files are created and maintained 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 and 182-186 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 character-
     istics:

     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                                           Locations

              Quarter                                                 5
              PSU - Random recode                                    6-8
              Week - Census code                                     9-10
              Segment                                               11-12
              Household Number                                      13-14
              Person Number (Blank on Household Record)             15-16
              Record Serial Number (Blank on Household and          17-18
                Person Records)
                                   
  2. File Sequence - continued

     The Quarter x PSU x Week x Segment x Household Number identifies a
     household.

     The Person Number identifies a person within a household.  Records belonging
     to a single family within a household can be identified by using the house-
     hold 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 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 335 bytes

     .4   Blocksize = 3350 (10 records per block)

 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 1991 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

 The data collected in the 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
 approach(1) is utilized in &REPERR-&PSALMS-OSIRIS.IV(2) to calculate the
 variance-covariance matrix.  SESUDAAN(3) SURREGR and SUDAAN(4,5) are programs
 that calculate the variance-covariance matrix using the linearization
 approach(6,7,8) (Taylor series expansion).

 In order to provide the user with the capability of estimating the complex
 sample variances in the NHIS data using the above procedures, we have provided
 the Basic Weight Before Age-Sex-Race Adjustment (loc. 172-177 - Person Record
 only), Substratum Identifier (loc. 178), Full Sample Stratum Identifier (loc.
 179-181), and Strata and Pseudo Primary Sampling Unit (PSU) (loc. 187-189)
 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.

 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 Person,
 Condition, and Doctor Visit Records.  The X of the Impairment Codes 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
         basic weight factor 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.

 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.  Locations from 237 onward 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 1991 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.
