PREFACE
The National Center for Health Statistics has as its mission the collection,analysis, and dissemination of data on the health of the population of the UnitedStates. One of the major programs is the National Health Examination Survey, inwhich extensive examinations of a sample of the U.S. population are conducted.Data from this survey have been published periodically in Series 11 reports ofVital and Health Statistics.
Historically, the published documents in Series 11 present only a small frac-tion of the availabl: data. In order to make additional data available for users, theCenter has for many years had a policy of preparing public use tapes for purchaseby persons interested in more detailed analysis or analysis of additional variablesnot published in Series 11 reports. However, these data are only accessible to per-sons with computers and support staff who can read, interpret, and analyze thedata. In order to make these data more generally accessible to many users and, inparticular, to persons not able to directly use data tapes, the Division of HealthExamination Statistics, in the autumn of 1977, initiated a program to release,along with the data tapes, basic descriptive summary tables of data contained inthose tapes. These tabular summaries have been termed “basic data publications,”of which this report is one.
These basic data publications present findings of the first National Health andNutrition Examination Survey of 1971-75. For each of the data sets, these publi-cations include information on the methods used to collect the data, a descriptivesummary of the tables included, an index to the tables, and the tables themselves.An appendix describes the basic format of the associated data tape. More detailedinformation on use of the data for additional analysis is avaiIable on request fromthe staff of the Division of Health Examination Statistics.

INTRODUCTION
This report presents findings on anthropo-metnc and goniometric measurements from thefirst National Health and Nutrition ExaminationSurvey, 1971-75. The survey, conducted by theDivision of Health Examination Statistics of theNational Center for Health Statistics, was de-signed to collect data by direct examination ofprobability samples of the U.S. civilian noninsti-tutionalized population 1-74 years. Data in-cluded measures of nutritional status as weIl asan assessment of hezdth and medical care needs.
The sample persons were examined in spe-cially constructed mobile examination centersthat were moved from location to locationaround the country. The field teams includedprofessional and paraprofessionzd mediczd anddental examiners and technicians, interviewers,and other staff who traveled to various loca-tions. A detailed description of the specific con-tent and plan of operation of the survey, in-cluding the sample design and forms used to col-lect the data, has been pubIished.1,2
The NationaI Center for Health Statistics hasalso published data on body measurements col-lected during Cycles I, II, and III of the NationalHealth Examination Survey-data was collectedin 1960-62 for adults ages 18-79 years (Cycle I),in 1963-65 for children ages 6-11 years (CycleII), and in 1966-70 for youths ages 12-17
years (Cycle 111). If the reader is interested inacquiring any of these reports, the CurrentListing and Topical Index to the Vital andHealth Statistics Series 1962-19773 should beconsulted.
The age, sex, and race distribution of theU.S. civilian noninstitutionalized population atthe midpoint of the survey and the distributionof the probability sample drawn from it are pre-sented in appendix 1. AIso in appendix I, the sta-tistical design for the first National Health andNutrition Examination Survey (NHANES I) andthe reliability of the estimates are discussed. Anillustration of the use of the standard error esti-mates and a formula for approximating standarderrors for estimates shown in the body measure-ment tables of this report are also presented inappendix I.
The definitions of certain demographicterms used in this report are found in appen-dix II. A summary of the anthropometic andgoniometric contents of the micro data tape usedin preparation of this report is found in appen-dix 111.Microdata tapes, including the one fromwhich the findings in this report were prepared,are available for purchase by persons interestedin more detailed analysis. The sample distribu-tion of all the variables on the microdata tapescan be found in the respective tape documenta-tation. Appendix IV contains methods and defi-nitions used in the collection of anthropometricand goniometric measures.
METHODS
Anthropometric Measurements
The examinees changed from their streetclothing into disposable paper examination uni-forms and foam rubber slippers designed to facil-itate and standardize as many elements of theexamination as possible. Body measurementswere made at various times throughout the dayat each examination center and in different sea-sons of the year and, thus, body measurementswere not standardized with regard to diurnal andseasonal variations.
Trained technicians, using standardized an-thropometric equipment, made measurementsquickly and at an acceptable level ojf accuracyand replicability. Multiple measurements weretaken until two results agreed within specifiedlimits. One member of the examining team, whowas responsible for observing and correcting anyerror in the measurement technique while aidingin the positioning of the examinee, acted as arecorder.
Where possible and applicable, all measure-ments were taken on the right side of the body.Left side measurements were taken if the rightside could not be used because of casts, amputa-tions, or any other reasons. Detailed explana-tions of the procedures used to determine thebody measurements included in this report arefound in appendix IV.
NHANES I primarily provided anthropo-metric data to evaluate the nutritional andhealth status of the population in regard togrowth, obesity, skeletal, and muscular devel-opment. Such evaluation depends prinlcipa.lly onthe physical measurements of the body andcomparisons with suitable standards of selecteditems of body measurements. Body measure-ments depend, in part, on the supply of nutri-ents and, thus, provided one method of assessingnutritional status. Heights and weights axe in-formative though limited in terms of body com-position. Body weight is influenced by suchcomponents as bone, muscle, and fat. The sepa-ration into its primary components provides theframework for description of the population’snutritional status. Therefore, the anthropo-metnc battery included height, sitting height,
weight, skinfoldlar), upper arm
thickness (triceps and sul~scapu-girth, and body dimensions (el-
bow and bitrochanteric breadths). Also includedwere measurements of chest circumference ofchildren 1-7 years of age and a special sublsampleof adults 25-74 years of age. In addition, thesebody measurements provide indices of over-weight, obesity, and muscularityy. Height,weight, growth, overweight, and obesity findingshave been published in previous reportsl~ andwill not be presented in this report.
The cross-sectional data on body measurem-ents were obtained on persons of differentages who represent different birth cohorts. Theage trends show the body measurement valuesfor successive birth cohorts of persons who wereof different ages when examined and reff,ect theeffect of different environmental as well ashereditary influences. The limitations of cross-sectional data in contrast to longitudinal dataare recognized in considering changes with age.
As suggested by the recommendations con-cerning body measurements for the characterizat-ion of nutritional status,g skinfold thicknessmeasurements were taken with a Lange s:kinfoldcaliper that was calibrated to exert a pressure of10 g per square millimeter of jaw surface. Thesemeasurements of adipose tissue are, thus, con-tained in the subcutaneous fat deposit that canbe characterized quantitatively by measuring thethickness of the skinfolds.
The measurement of skinfold thickness isone of a number of methodsl 0-1z used to de-termine the body fatness of individuals. It is lessinvolved, does not require sophisticated hard-ware, and can provide accurate results. In thisregard, the taking of skinfolds has distinct ad-vantages. Their measurement does not requireelaborate, expensive, or timely procedures and,particularly for field studies, are recommendedas an integral element in body composition re-search.13 The taking of skinfolds is the easiestand most direct approach to the measurement ofbody fat. The validity of skinfolds as measuresof body fat has been proven an acceptable sur-vey method. This approach involves the meas-urement of a double fold of subcutaneous tissueplus skin, pulled away from the underlying tis-sue at a predetermined site on the body.
With regard to skeletal structure, two directanthropom~tric measures were taken-elbow andbitrochanteric breadth; both measures are unaf-fected by degree of adiposity and are closelyrepresentative of bony dimensions.
Upper arm girth is a measure of three bodycomponents—bone, muscle, and fat. The upperarm diameter, corrected for the thickness of thelayer of subcutaneous fat (triceps skinfoldthickness), may serve as a criterion of musculardevelopment.
Goniometric Measurements
Goniometry means the measurement of an-gles. More specifically, in the NHANES I survey,it means the measurement in degrees of therange of motion of specific joints whose naturalanatomical position is generally considered to bezero degrees. All goniometric measurementswere taken with a double-armed Universal goni-ometer, pivoted over the axis of motion of thejoint of interest. Since the axis of motion couldshift somewhat if the joint were to move, carewas taken to make sure the pivot of the goni-ometer was as close as possible to the axis whenthe measurements were made.
Goniometric measurements were taken toascertain the range of motion of certain joints ina special subset of NHANES I adults 25-74 yearsof age. Specifically, 16 measurements were takeqinvolving the extension, flexion, abduction, ad-duction, internal and external rotation of bothhips, and extension and flexion of the knees. Nogoniometric findings are presented in this reportfor adduction of the right and left hip and ex-tension of the right and left knee since few samp-le persons were found to have nonnormal val-ues for these measures. Detailed explanations ofthe procedures used in the goniometric examinat-ion are given in appendix IV.
Using a procedure similar to that utilized inthe determination of body measurements, twotechnicians were employed in the collection ofgoniometnc data in an attempt to insure accu-rate reading and recording of the measurements.One of the technicians acted as the examinerwhile the second technician recorded the meas-urements on the examinee’s form. As each
measurement was completed, its wdue was dic-tated to the recorder. The recorder repeated thevalue aloud for verification and then entered iton the examinee’s form.
These efforts to reduce errors may not havebeen sufficient. The original plan called for thecollection of this data for all 65 stands of thesurvey, but investigations into the quality of thedata showed that a satisfactory level of repro-ducibility was not being achieved. The collectionof goniometnc data was discontinued after the35 stand subsarnple was complete.
In this context, reproducibility is defined asthe equaIity or similarity of replicated values ofthe same measurement on the same person. Re-producibility is a function of both technicianperformance and the inherent variability of thegiven measurement. The inherent variability is inturn, at least partially, a function of the degreeof effort-dependence with the more effort-dependent measurement being generally lessreproducible.
Most goniometnc measurements are highlyeffort-dependent. In light of the strenuous ef -forts made to maximize technician performanceand recording accuracy, it seems likely that thelack of reproducibility is due almost entirely tothe inherent variability (effort-dependency) ofthe measurements; therefore, technician retrain-ing or procedural modifications would not sig-nificantly increase the level of reproducibilityy.
When a satisfactory reproducibility criterionis not met, making inferences solely from esti-mates derived from the data may be somewhatmisleading. However, if inferences have to bemade, this subsample of 35 stands represents thebest estimates available. Moreover, the goni-ometric data may be used with other data gath-ered in the survey to collectively produce morereliable estimates of specific health conditions inthe civilian noninstitutionalized population ofthe United States~

Triceps and subscapular skinfolds. –Compar-isons in this report of skinfold measures arebased on medians rather than means since themarked skewness of the skinfold distributionssuggests the use of the median as the bettermeasure of central tendency.
The differences between sexes in limb fat, asmeasured by the triceps skinfold, are particu-larly evident in adults (tables 1-4 and figure 1).In 22 of the 24 age groups from 1-74 yearsshown in the tables, the median triceps skinfold
females exceeded those for males. Inthe other two age groups (ages 1 year and 2years), the median triceps skinfolds for malesand females were equal.
After age 11, the median triceps skinfoldvalues for females substantially exceeded thosevalues for males, reaching a peak of 2!5 mm(millimeters) at ages 45-64 years. The peak tri-ceps value for males was only 12 mm and wasreached at ages 25-44 years.
With one exception, the observed n~ediantriceps skinfold for white males was greatei thanthat for black males for all the selecte# agegroups (figure 2). The pattern observed fbr fe-males was different. In the age groups 1 year to20-24 years white females generally had higher

females had higher mean values than white fe-males, and in the older age groups, they had thelargest observed mean values of all four sex-racegroups. Since bone and muscle do not increaseat these ages, the increases in upper arm girth forblack women are probably due to larger in-creases in arm subcutaneous tissue.
Elbow breadth. –The differences in elbowbreadth between males and females were smallin children ages 1-12 years, with boys havingmean values equal to or slightly greater thanthose of girls at all ages. After age 12, the differ-ences in mean elbow breadth between males andfemales increased and remained fairly constantat about 1 cm all through adulthood (tables13-16).
Other body measurements.-Tables 17-20present findings for sitting height, a measure ofupper and lower extremity lengths. Due to aprocedural problem, many sitting height meas-ures for children 2 years of age were not done.While information for 2 year olds is presented inthis report, the data do not represent a nationalprobability sample and are included for compar-ative purposes only. Distributions of bitro-chante~ic breadth are found in tables 21-24.Table 25 presents findings for chest circumfer-ence of children 1-7 years of age. In addition,chest circumferences at full inspiration and fullexpiration are presented for a special subsampleof adults 25-74 years of age (tables 26 and 27).
Czme smoothing. –In addition to presentingobserved dktributions of skinfolds and upperarm girth (arm circumference) for chiIdren ages1-17 years from NHANES I, smoothed percen-tile curves are presented. These curves were pro:duced by utilizing the same smoothing techni-que employed in the production of the NCHSGrowth Charts.8 The National Health Examina-tion Survey Cycles II and 111 and NHANES Idata were pooled for persons aged 1-20 by sexand half-year age groups as shown in tables 28-30, and smoothed percentile curves were derivedfor children aged 2-18 years. The data for thesmoothed percentile triceps skinfold, subscap-ular skinfold, and upper arm girth curves forchildren aged 2-18 years by sex and half-year agegroups are presented in tables 31-33; the cor-responding smoothed percentile curves areshown in figures 5-10.
The skinfold thickness percentiles providedistributions of these measures among the U.S.population of children and youth ages 2-18years from 1963-74. The general concensus isthat some proportion of the U.S. population inboth children and adults is probably too fat.Presently, it is inappropriate to conclude that askinfold thickness above or below some arbitrarypercentile or number is unacceptable; availabledata are insufficient to define or valdate risks ofrelative fatness. We do know that the subscapu-Iar skinfold correlates better with serum totalcholesterol, HDL-cholesterol, triglycerides, andblood pressure than the triceps skinfolddoes}q-1s We also know that both the tricepsand subscapular skinfolds seem to correlatebetter with estimates of total body fat in chil-dren than weight, height, weight-for-heightratios, or power functions of weight and heightdo>6-19
From examination of central data, that is,the 25th to 75th percentiles, the secular changeamong children of the same sex and age exam-ined in 1963-65 and 1971-74 does not appear tohave been significant. This finding suggests thatthese percentiles, which incorporate both peri-ods, can provide useful references for compari-sons with other populations of children such asthose included in nutrition surveys or in nutri-tion surveillance programs.
With the merger of data from NHES II,NHES 111, and NHANES I, reasonable numbersof children represented in the given age and sexgroups exist. Still, the percentile curves as pre-sented have been smoothed considerably fromthe observed data.
This finding is especially true at the 5th,10th, 90th, and 95th percentiles. Clinical em-phasis in use of these skinfold curves will befocused largely at the extremes, that is, is thischild too fat or too skinny? However, consid-erable caution must be exercised in use of thesereference data to avoid identifying or labellingindividual children included in surveys or screen-ing programs as excessively lean (thin) or fat(obese) on the basis of single skinfold measure-ments.
It is more difficult to measure triceps or sub-scapular skinfolds in the infant than in the olderchild or adolescent. The clinician dealing with

preschool children and preadolescents may pre-fer to measure weight and height periodicallyand measure skinfolds only when weight-for-height shows a trend towards higher percentiles.Skinfolds should be measured periodicallythroughout childhood, thereby providing a po-tentially useful indicator of the trend of relativefatness in the individual child. Knowledge ofthis trend during the preadolescent years may behelpful in interpreting skinfold thickness meas-urements during adolescence.
Although these percentiles constitute ,distri-butions of triceps and subscapular skinfoldthickness for U.S. children at various ages, theyshould not be interpreted as fat growth curves.Differences in fatness reflecting racial and socio-economic differences are obscured within thesepercentiles. This situation is especially true dur-ing adolescence where differences in relativefatness in individuals of the same sex, chrono-logic age, race, and socioeconomic status arefound. These differences in relative fatness re-

Goniometric Measurements
A description of the measuring techniquesand diagrams used in the goniometric examina-tion is located in appendix IV.
Extension of right and left hip. –About 90percent of the adult population is capable of ex-
tending each hip in the range of 170-150 degrees(tables 34 and 35). Of those individuals incapa-ble of extending their right hip into the range of175 degrees or less (e.g., who could move itno more than 5 degrees from the 180 degreeplane), approximately 6.4 percent are females,3.4 percent are males, 4.5 percent are white, and9.7 percent are black. Of those incapable of ex-tending their left hlp less than 175 degrees, ap-proximately 5.5 percent are females, 2.1 per-cent are males, 3.4 percent are white, and 8.4

percent are black. In general, a larger proportionof females and white adults are capable of ex-tending their hips through a larger arc (as meas-ured here a smaller angle) than males and blackadults.
Abduction of raght and left hip. –Tables 36and 37 show that 16.3 percent of adults canabduct either hip 145 degrees or more.
Flexion of right and left hip. –Tables 38 and39 present findings on the flexion of the rightand left hip. About 25 percent of the blackpopulation, compared with about 49 percent of
the white population, have flexion of the righthip less than 60 degrees. Correspondingly,’ forthe left flexion, the proportions were 31 and 50percent, respectively. Noted is the tremendousdifference in the proportions between black andwhite persons who are capable of flexing theirhips to small angles. There is virtually no differ-ence in the proportions for males and femaleswith flexion of the right or left hip less than 60degrees.

can internally rotate their right hip between 50and 70 degrees (table 40); correspondingly,about 84 percent can externally rotate their lefthip between 50 and 70 degrees (table 41). Table42 shows that 46 percent of the adults arecapable of externally rotating their right hip be-tween 120 and 125 degrees; the proportion iscomparable for internal rotation of the left hip—about 50 percent (table 43).
Flexion of right and left knee. –In general,white adults are more capable of flexing theirknees to smaller angles than black adults. About
90 and 80 percent, respectively, can flex theirright knees to less than 60 degrees (table 44).Table 45 shows that the difference in the pro-portions is even larger for the left knee (about90 and 77 percent, respectively). However, ifflexion less than 70 degrees is considered, thereare virtually no differences between the races. Ineach of the flexion categories, the proportionsachieving small angles generally decreases withage, reflecting that the proportions with poorflexion of the knees is higher in the older agegroups, particularly ages 65-74 years.

APPENDIX I
STATISTICAL NOTES
Survey Design
The sample design for NHANES I is basicallya three-stage, stratified, probabilityy sample ofIoose clusters of persons in land-based segments.The sample was designed to be representative ofthe civilian noninstitutionalized population, ages1-74 years, living within the coterminous UnitedStates, with the exception that all persons re-siding upon reservation lands set aside for theuse of American Indians would be excluded.
In the first stage of the design, 100 primarysampling units (PSU’S) were selected with prob-ability proportional to size from the approxi-mately 1,900 PSU’S into which the UnitedStates has been divided. (Ten of the PSU’S wereselected into the sample twice, so that in factthere were only 90 distinct PSU’S selected.) APSU consists of a county, a smalI group of con-tiguous counties, or a standard metropolitan sta-tistical area. Before selecting the 100 PSU’S forinclusion in NHANES I, the approximately1,900 PSU’S were first grouped into 40 strata ofwhich 15 contained ordy one PSU, consisting ofa single large metropolitan area with a popula-tion of more than 2 million. All 15 of the largestPSU’S and three PSU’S from each of the other 25strata were selected. In the nutrition examina-tion component in NHANES I, two PSU’S fromeach of the other 25 strata were selected result-ing in a total of 65 PSU’S for this componentsample design.
At the second stage of the design a sample ofsegments, consisting of approximately sixhouseholds each, was systematically selectedwithin each selected PSU. Although the 1970census data were used as the frame for samplingwithin PSU’S when they became available, thecalender of operations required that the 1960
census data be used for the first 44 selectedPSU’S. Generally, three types of segments wereused: (1) segments from the Census ListingBooks that were created in taking the popula-tion census, (2) area segments that are definedgeographically, and (3) permit se~ents, usingupdated lists of building permits issued in sam-ple PSU’S since January 1970.
At the third stage of sampling, a list of alleligible persons was made within each selectedsegment. From this list, persons were then sys-tematically selected for inclusion in NHANES 1.
A more complete description of the surveydesign is included in Vital and Health Statistics,Series 1, No. 10al and supplemented in Series 1,No. 14.2
Because the design of NHANES I is a multi-stage probabilityy sample, it is necessary to usecomplex procedures in the derivation of esti-mates. Three basic operations are involved.
Inflation by the reciprocal of the probabilityof selection. The probability of selection is theproduct of the probabilities of selection fromeach step of selection in the design (PSU, seg-ment, and sample person).
Nonresponse adjustment. –The estimates areinflated by a muItipJ.ication factor calculatedwithin each PSU for each of five seIected incomegroups. The numerator of these factors consistsof the sum of the weights for sample persons re-sulting from the reciprocal of the probability ofselection and the denominator consists of thesum of the weights for examined persons also re-sulting from the reciprocal of the probability ofselection.

Posts gratification by age-sex-race. –The esti-mates are ratio adjusted within each of 60 age-sex-race cells to an independent estimate, pro-vided by the U.S. Bureau of the Census, of thepopulation of each cell as of the midpoint of thesurvey. The ef feet of the ratio-estimating processis to make the sample more closely representa-tive of the civilian noninstitutionalized popula-tion by age, sex, and race, which thereby re-duces sampling variance.
In NHANES I the locations were drawn forthe detailed examination component so that lo-cations 1-35, 1-65, 66-100, and 1-100 are sepa-rate but overlapping probability samples of thecivilian noninstitutionalized population ages 25-74 years. Examinations for the first 65 locationswere conducted between April 1971 and June1974. For the remaining 35 locations, examinat-ions were started in July 1974 and completedby October 1975. The total examined samplepopulation and the estimated U.S. populationfor locations 1-35, 1-65, and 1-100 are presentedin tables I, H, and III.
Missing Data
Examination surveys are subject to the lossof information not only through the failure toexamine all sample persons but also from thefailure to obtain and record all items of infor-mation for examined persons. For a number ofexaminees, one or more of the anthropometncmeasurements were not available. The extent ofthese missing measurements is indicated in tableIV. The number of missing goniometric meas-ures is in table V.
For most measures, estimates for missinganthropometric data were made on the basis ofa multiple regression type decision, substitutingfor the missing measurements those of an indi-vidual who was of the same age, sex, and race,and had other dimensions similar to those avail-able for the examinee with incomplete data.Skinfold measurements recorded as “tight skin”were imputed using the same procedure as thosethat were not recorded.
For those few sample persons with no an-thropometric measurements available, a respon-dent of the same age-sex-race group was selectedat random and his measurements were assignedto the nonexamined person.

No imputations were done for the chest cir-cumference measurements on the special sub-sarnple of adults 25-74 years of age. In addition,there was no procedure defined to estimatemissing data for the goniometric measures.
All findings for these data are based only onobserved measures from examined persons.
53
Parameter and Variance Estimation
Because each of the sample persons has anassigned statistical weight, all estimates of popu-lation parameters presented in NHES publica-tions are computed taking this weight into con-sideration. Thus the estimate of a populationmean p is computed as follows:
where ~ is the observation or measurement onthe ith person and Wi is the weight assigned tothat person.
The Health and Nutrition Examination Sur-vey has an extremely complex sampling plan,and obviously the variance estimation procedureis, by the very nature of the sample, complex aswell. A method is required for estimating thereliability of findings that “reflects both lossesfrom clustering sample cases at two stages andthe gains from stratification, ratio estimation,and poststratification .“20
The method of estimating variances inNHANES I is the half-sample replication tech-nique. The method was developed at the U.S.Bureau of the Census prior to 1957. The half-sarnple replication technique is particularly wellsuited to NHANES I because the sample, al-though complex in design, is relatively small(20,749 persons) and is based on only 40 strata.This feature permitted the development of avariance estimation computer program that pro-duces tables containing desired estimates of ag-gregates, means, and distributions, together witha table identical in format but with the estima-ted variances instead of the point estimates. Thecomputations required by the method are sim-ple, and the internal storage requirements arewell within the limitation of the IBM 370-158computer system used at the National Center forHealth Statistics.
Variance estimates of anthropometric pa-rameters computed for this report were basedon 40 balanced half-sample replications. A half-sample was formed by choosing one sample PSUfrom each of 40 pairs of sample PSU’S. To com-pute the variance of any statistic, this statistic iscomputed for each of the 40 half-samples. Thenthe weighted mean of the entire undivided sarn-
NOTE: A list of references follows the text.
54
ple is computed. The variance of the mean is themean square deviation -of each of the 40 half-sample means about the overall mean. Thestandard error of the mean is simply the squareroot of this variance of the mean. In a similarmanner, the standard error of any statistic maybe computed. Variance estimates for gonio-metnc statistics included in this report werecomputed in a similar manner to those for an-thropometric measurements, but were bas$d on20 balanced half-sample replications d&ivedfrom the first 35 locations from NHANES {.
In order to eliminate many of the tables re-quired to present variance estimates for all thestatistics in this report, a “variance smoothing”approach has been used for the presentation ofestimated variances for the anthropometricmeasures.
By using this approach, a variance estimatefor a sample mean (Xi) is produced in two steps.First the simple random sample (SRS) estimateof variance is calculated by squaring the stand-ard deviation of the sample (Sxi) and dividing
by the size of the sample (ni). This step id sum-marized with the following equation:
VAR~w (~) = (sXi)2/ni
Secondly, the SRS estimate of varia.qce ismultiplied by a design effect (defined as theeffect that the complex sampling design has onthe magnitude of the variances) that correspondsto the variable of interest (e.g., type of bodymeasurement by race by sex by age) to producethe variance estimate of ~.
The design effects were estimated by themethod of least squares. The replicated ~half-sample variance estimates presented were usedas the dependent variables and the correspond-ing SRS variance estimates were used as ~inde-pendent variables in the model
VAR(~) = (desigm effect) X VAR~w (~)+ .s
to produce the estimates of the design effects.The estimated design effects and the correla-
tion between the half-sample variance estimatesand the “smoothed” or predicted variance esti-mates (giving a measure of strength of the rela-tionship between the two, that is, the effective-ness of the fitting process) are given in table VI.

The following exampIe may be illustrative. andThe variances for the mean sitting height ofblack and white males age 13 years (denoted by VAR~M (YB) = (4.4)2/45 = .430XB and lizW,respectively) are estimated using thefollowing calculations: thus, the estimated variances are
The variances used in all significance testspresented in the main text for the anthropo-metric measurements employed this technique.
The usual test for the difference betweenmeans (where the estimated variances are treatedas constants and the covariance between themeans is ignored) is used to determine
z = (XW - XB)/ VAR(XW) + VAR(YB )
for the example described in the parajy-aphabove,
Z = (82.32 - 78.87)/~~1~
z =3.37 (p<o.ol)

prior to the examination. The age criterion usedin this report was defined as the examinee’s ageat the time of the examination. Twent y personswho were 74 years of age at the time of the in-terview became 75 years of age at the time ofthe examination. In the adjustment and weight-ing procedures used to produce national esti-mates, these persons were included in the 74year age group.
Race. –For each individual, race was re-corded as “white,” “black,” or “other races.”The last category included American Indians,Chinese, Japanese, and all races other than whiteor black. Mexican persons were included with“white” unless definitely known to be a raceother than white. Black persons and persons ofmixed black and other parentage were recordedas “black. ”

MEASURING
Anthropometry
APPENDIX IV
PROCEDURES AND DEFINITIONS
Eat-h meas&-ement is taken by the examiner,read to the nearest tenth of a centimeter (exceptskinfolds which are taken to the nearest half of amillimeter) and said to the recorder. If a skin-fold is too tight to be measured, “too tight” iswritten in the recording space for that measure-ment (figure I). The recorder repeats the num-ber, records it in the proper space, and says thename of the next measurement. The examinerkeeps the measuring instrument set until therecorder repeats the number. If the anthropom-eter becomes unset in any way before themeasurement is read back, the measurementshould be read again. On standing measure-ments, the recorder will insure that the subjectstands erect.
The recorder is important not only to insurethe accurate recording of the measurement butalso to assist the examiner in positioning theexaminee correctly. The recorder also aids theexaminer by seeing that the steel tape is hori-zontal with the proper tension when girths aremeasured. The recorder, having had the sametraining as the examiner, should recognize an er-~or in measurement or in reading from thewrong scale. (The anthropometer has twoscales-ascending and descending.)
For the following six measurements the ex-aminee was asked to stand with his feet togetherin the standard erect position.
Bitrochanteric breadth. –The maximumbreadth of the body at the level of thefemoral trochanters was measured with thetop section of the anthropometer (figure II).
Elbow breadth.–The examinee’s right armwas extended forward perpendicular to the
body. With the arm bent so the angle at theelbow forms 90 degrees with the fingerspointing up and the dorsal part of the wristtoward the examiner, the greatest breadthacross the elbow joint was measured withthe sliding caliper along the axis of the upperarm.Upper arm girth.–The examinee’s right armwas flexed 90 degrees at the elbow. The steeltape was used to measure the distance fromthe acromion to the end of the humerus tomark the lateral part of the arm at its mid-point. Now with the arm hanging freely, thecircumference of the upper arm at themarked level was measured. The examinerwas instructed not to compress the tissue.
Chest circumference (l-7 yeam).-Wlth thechild’s shirt removed, the chest circumfer-ence was measured at the nipple line withthe child breathing normally, arms at hissides. The steel tape passed around thechild’s back about 2 inches above the base ofthe scapula.
Chest circumference (Detailed exam only). –These chest girths were measurements ofthe bony rib cage only, not tissue measure-ments, and were made at the levels of thefourth intercostal space.
A. Full expiration. –The examinee wascoached to take in a deep breath andthen really let it M out.
aTo find this level, palpate the sternal-manubnumjunction which is at the level of the second intercostalspace. Count down two intercostal spaces from thispoint to the fourth intercostal space. The tape waspassed around the examinee’s chest at this level.

B. Full inspiration. –The examinee wasasked to take in a “great big deepbreath” for the measurement to bemade.
Triceps skinfold. –With the examinee’s armhanging freely at his side the skinfold calipermeasured the thickness of a fold of skin plussubcutaneous tissue, but no muscle, takenover the right midtriceps at the level previ-ously marked. The crest of the fold wasparallel to the long axis of the arm. Thecalipers were applied about 1 cm below thethumb and forefinger.
Subscapular skinfold. –The thickness of afold of skin taken just below the angle ofthe right scapula (shoulder and arm relaxed)was measured. The fold was parallel to nat-ural cleavage lines of the skin-often a line45 degrees from the horizontal extendingmedially upward.
Sitting height (2 years and over). –The ex-arninee sat erectly on the measuring tablewith his eyes straight ahead and the infra-orbital meatal line parallel to the table top.Sitting as far back as possible with feet onthe appropriate step of the stool so that thethighs were horizontal with the poplitealfossa at the table edge, the movable caliperarm was brought down firmly against themidline of the examinee’s head.
Goniometry
Below is a complete description of the pro-cedures of the goniometnc examination.
Extension of hip (Figure III)
1.

3.
Have the examinee lie on his sto]mach withboth hips firmly resting on the table.
Ask him to lift his entire near leg as high ashe can without bending his knee or liftingeither hip off the table.
Have him relax and then repeat the pro-cedure.

Have him relax the leg and then repeat theprocedure.
Place the stationary arm of the goniometeralongside and parallel to the long axis of thetrunk and the movable arm along the lateralmdine of the femur with the pivot pointover the greater trochanter.
Take the measurement, which shouId nor-mally be an angle between 180° and 55°.
Abduction and adduction of h+ (Figure V)
1. Have the exarninee Iie on his back with bothlegs straight and together. The adduction ofthe hip is normally an observed measure ofzero degrees. (If it isn’t, then measure andrecord the correct angle of adduction. Sub-tract the angle from 180° and record it as atwo-digit number.)
2. Tell the examinee that you are going tocarry the weight of his leg while he relaxesand moves his leg as far sideways as possible.
3. While You are holdinE his leg with the kneestraight, have the exa&inee move his leg outto the side.

Have him relax and repeat the procedurewhile putting one finger on each of his ante-rior superior iliac spines.
Place the stationary arm of the goniometeracross the pelvic area along the line betweenthe anterior superior iliac spines with thepivot point over the anterior superior iliacspines of the leg being measured.
Place the movable arm along the anteriormidline of the femur and measure the ab-duction of the hip.
Read and record the obtuse angle betweenthe arms of the goniometer. ‘This angleshould be between 90° and 140°.
Internal and external rotation of h$ (Figure VI)
1. Have the exarninee sit with his legs over theside of the table and knees flexed to 90degrees.
2. Making sure he does not raise his hips fromthe table, have him swing one leg and thenthe other to the inside as far as he can andthen to the outside as far as he can.
3. Have him relax and repeat the procedurewhile you measure.

Place the stationary arm in your right handand hold it parallel to the table top.
With the anterior aspect of the knee as apivot point and with the movable arm of thegoniometer along the anterior tibial crest,follow the leg in and take the measurementof internal rotation.
Follow the leg out and take the measure-ment of external rotation.
For the measurements of external rotationof the right hip and internal rotation of theleft hip, the angle should be between 90°and about 140°.
For the measurements of external rotationof the left hip and internal rotation of theright hip, the angle should be between about40° and 90°.
Extension and jlexion of knee (Figure VII)
1. Have the examinee lie on his back with legsextended. The extension of the knee is nor-mally an observed measure of zero degreeswith the back of the knee flat on the table.(If not, then measure and record the correctangle of the knee while the leg is extended asfully as possible. Subtract the angle from.180° and record it as a two-digit number.)
