 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)

     .5   Tape format = All fields are in character format.

     .6   Data Set Names:

 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 1993 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.

 CHANGES IN THE 1993 PUBLIC USE TAPE COMPARED TO 1992

 The 1993 Public Use Tape resembles the 1992 version, with a few exceptions.
 The most notable change was the expansion of the race categories.  The
 location and code differences are described below:

 PERSON, CONDITION, DOCTOR VISIT,
 AND HOSPITAL RECORD VARIABLE:

 Tape Location                Item and Codes

                              (In 1992, the Main Racial Background
                              field was expanded from a one position
                              field to a two position field)

    169                       Blank

 NOTE:  In 1992 some deletions and additions occurred to the Detail and
        Standard Industrial Classification and Standard Occupational
        Classification codes which caused changes to occupation and
        industry recode categories.  Please see appendixes B and C for
        complete listing of these codes.

 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.

 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.  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 1993 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.
