 GUIDELINES

 With the goal of mutual benefit, NCHS requests that recipients of data tapes
 cooperate in certain actions related to their use.

 Any published material derived from the data should acknowledge the National
 Center for Health Statistics as the original source.  It should also include a
 disclaimer that credits any analyses, interpretations, or conclusions reached
 to the author (recipient of the tape) and not to NCHS, which is responsible
 only for the initial data.  Consumers who wish to publish a technical
 description of the data should make a reasonable effort to insure that the
 description is not inconsistent with that published by NCHS.

 Tape formats, diagnostic recodes, and guidance on weighting and procedures for
 deriving estimates from National Health Interview Survey data tapes are
 included in this volume.  Detailed technical information is also contained in
 the following publications and documents which accompany the NHIS Public Use
 Data Tape Package.  Additional copies of the documentation may be purchased

 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 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 house
          hold (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

          Household Number                                      13-14
          Person Number (Blank on Household Record)             15-16
          Record Serial Number (Blank on Household and          17-18
            Person Records)


    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.

     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 1986 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) and SURREGR,(4) are programs that
 calculate the variance-covariance matrix using the linearization
 approach(5),(6) (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
 Strata and Pseudo Primary Sampling Unit (PSU) codes on all data tapes in
 positions (187-189).  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.

 An NCHS Series 2 publication discussing these issues is in process.  Detailed
 information from this publication on calculating variances and the use of
 sample weights is available, upon request, from NCHS.

 CHANGES IN THE 1986 PUBLIC USE TAPE COMPARED TO 1985

 The 1986 Public Use Tape resembles the 1985 version, with only one exception.
 This difference is described below:

 HOUSEHOLD VARIABLES:

 Tape Location

    182           The label of "Midwest has been substituted for "North
                  Central" in accordance with current Census Bureau usage.  The
                  states included remain the same.

 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.

 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.

 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.

 To illustrate the use of reference periods, suppose we have a person whose
 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.


 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 1984 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.
