THIS REPORT presents and analyzes data on standing height and on 

weight of children aged 6 through 11 years in the United States, India, 

and the United Arab Republic (Egypt). Data for all three countries come 

porn representative national samples and present the first opportunity 

to compare data from several countries that are bvoadly representative 

of the respective populations of children. The present ckzta provide 

basic nwms which have long been needed. 

The variability of height and weight with age and with sex is veYy simikzr in each of the three countries. The level of the values, however, is 

clearly diflavent in each of the three. The means and the percentiles 

for both height and weight are markedly higher for children of the 

United States than for children of the other two counties. Indian children had the lowest mean Flues, and the heights and weights of children of the United Arab Republic fell between those of the other two 

countries, but somewhat closer to those fov Idia. 

Heights of children have increased during the past half century. While 

no tvuly comparable national data exist for earlier periods, it is of interest that the available but limited data on height of children of the 

United States around the turn of the century ave slightly lower than 

the current olzta fov childven of Egypt and are slightly higher than 

those for children of India. 

The report presents information on the samples in the three countvies 

and discusses, the sampling error and measurement mors in the daka. 
HEIGHT AND WEIGHT OF CHILDREN


IN THE 

UNITED STATES, INDIA, AND THE UNITED ARAB REPUBLIC 

Arthur J. McDowell, Anand D. Taskar, 

INTRODUCTION 

Measurements of height and weight are of 

interest from various points of view. Aside from 

their usefulness to persons concerned with human 

engineering problems such as, say, seat design, 

they are related to health. This is particularly 

true when the measurements are for children, 

since they reflect the process of growth and 

development and may be affected by nutritional 

factors. 

The National Center for Health Statistics has 

as one of its major programs the Health Examination Survey program. This program is carried 

out as a series of separate surveys concerned 

with the direct examination; testing, and measuring (including body measurements) of probability samples of specific segments of the lJ.S. 

population to obtain a wide range of health related 

data. The Center also sponsors a number of 

projects in various parts of the world as part of 

the Special International Research Programs 

authorized by Public Law 480 to utilize foreign 

currency in scientific research (Special Foreign 

Credit Programs funded research). Two of the 

projects involved the tabulation and analysis of 

large sets of data which include some body 

measurements of children of India and Egypt. 

Some of the same kinds of data available from 

aArthur J. MoDowell, Director, Division of Health Examination Statistics, National Centsr for HeaLth Statistics; 

Anmd D. TtuAar, Chief, Divieion of Biostatistics, Indian 

Council of Medical Research, New Delhi, India; Ahmed E. 

Sarhan, Dean, Institute of Statistical Studies and Research, 

University of Cairo, Egypt. 

Ph.D., and Ahmed E. Sarhan, Ph.D! 

these two programs have been collected in the 

Health Examination” Survey for children of the 

United States. 

The present report gives data on standing 

height and on weight of children aged 6 through 

11 years for the United States, India, and the 

United Arab Republic (Egypt). Data are considered 

separately by sex and individual years of age. 

Means are shown along with their standard deviations. Percent distributions and selected percentiles for height and weight distributions are 

also shown. Percentiles for mean weight are 

cross-classified by grouped intervals of height 

to the extent that the data permit. 

In presenting these data, their limitations 

are acknowledged. Body measurements other than 

height and weight—perhaps particularly certain 

skinfold thicknesses and girths-are also useful 

in making assessments related to such aspects 

of health as obesity or malnutrition. Considerable other data, including body build information, dietary intake records, clinical evaluations, and certain laboratory test results, would 

be important elements in any complete assessment 

of the nutritional state of a population. Moreover, 

there are restrictions on the kinds of uses in 

studies of growth and development that can be 

made of height-weight data collected through a 

cross-sectional survey, as distinguished from 

longitudinal data when the interest is primarily 

upon the velocity of growth and particularly upon 

the variability in that velocity.1 

The present data are cross-sectional. Moreover, national averages for each of the countries 

involved conceal the differences that exist within 

1

each country arncmg various subgroups (regional, 

ethnic, racial, religious). Other repormhave keen 

or will be prepared exami.ling height and weight 

data for each country in more detail with respect 

to some of these variables; none of them are 

treated !lere. 

Despite all the foregoing limitations, these 

data are important in their own right. This is 

the first time that any complete national data 

on the height and weight of children aged 6 

through 11 years have been available for any of 

these three countries. In each country the data 

have been collected with considerable concern 

for standardization of measurement techniques 

and uniformity of recording procedures. In each 

DESCRIPTION 

CHILDREN OF THE UNITED STATES 

General 

Data for the United States were obtained 

from one of the programs o~ the Health Examination Survey. This program involved, along 

with body measurements, a variety of tests and 

procedures, including medical, dental, and psychological examinations. Subjects were a probability sample of all noninstitutionalized children 

aged 6 through 11 years. From July 1963 to 

December 1965, the survey staff completed examinations on 7,119 children, 96 percent of the 

7,417 sample children. A detailed description of 

the sampling process, the operation of the program, ~and the response results has been published.” Some of these matters need to be 

described briefly to assist in understanding 

and evaluating the data. 

Sample Design 

The National Center for Health Statistics 

set specifications for the sample of U.S. children 

and developed the overall design. The steps of 

drawing the sample were carried out jointly with 

the U.S. Bureau of the Census under a contract 

arrangement. The starting points were the decennial census lists and the nearly 2,000 primary 

sampling units (P SU’s) into which the entire 

2 

country thousands of children were included in 

the study, and they were selected to constitute 

representative samples of all children 6 through 

11 years. The data for each country have been 

presented in a standard manner and show not 

only the average values but the dispersion around 

the averages. An effort has been made to make 

some evaluation of the sampling error and the 

measurement error that may persist in the data. 

Measurements of height and weight continue to be 

important indexes of the progress of a child 

through his stages of growth. and development 

and of a nation’s progress in the field of health. 

The. present data p~ovide basic norms which have 

been long needed. 

OF THE DATA 

United States is divided. These PSU’S were 

grouped into 40 superstrata (a somhining of an 

earlier grouping into a larger numker of strata). 

In this process the areas were classified by broad 

geographic region, by population density classes 

(degree of urbanization), and by rate of change 

of population between two decennial censuses. 

Through a process of controlled selection, specified numbers of clusters of households, called 

segments, were selected. Interviewers visited 

each household in the selected segments to 

obtain data on household composition that could 

be used in the final random selection of sample 

children. 

The foregoing description of the sample 

design is so,mewha: oversimplified. For example, 

provisions were made to supplement the original 

data, taking into account persons who had moved 

into the area subsequent to the census. The 

strata were selected so as to be roughly equal 

in population, so that, with approximately the 

same num!,,er of children coming from sach 

stratum, the total sample would be essentially 

self-weighting. The estimai ion process developed 

for use with the sample design, however, included 

an adjustment for nonresponse (even though a high 

response rate was achieved) and also included 

poststratification ratio adjustments. These insured that the weighted totals would equal the 

age, color, and sex distributions of the corresponding U.S. population figures derived independ-
ently ‘by the Bureau of the Census for the survey. 

h seems reasonable to assume that the sample, 

although relatively small, is representative of 

the U.S. population of noninstitutionalized children 

aged 6 through 11 years. 

Plan of Survey Operation 

Data on U.S. children were collected in the 

40 different locations chosen in the sample design 

of the Health Examination Survey. However, each 

area had the same physical setting for the entire 

examination, including the measurement process 

for height and weight. Specially designed mobile 

examination centers, consisting of several tractor-drawn trailers, were moved into each of the 

areas. Sample children were brought into the 

center at scheduled times throughout the day. 

The clothing worn during the examination was a 

standard uniform provided by the survey, consisting of gym-type shorts, a standard shirt or 

shirtwaist, socks, and a robe. The robe was removed during the weighing process. 

Data “on U.S. children were collected during 

the period July 1963-December 1965. The basic 

source document was the household questionnaire, 

which provided considerable information about 

each potential sample child and was used in the 

final stages of sample selection. Information 

obtained included the age and birthplace of the 

child. The latter was used to request a copy of 

the birth certificate from the appropriate registrar’s office (State or city). 

The survey operation made every effort to 

insure complete standardization of the measurement process. (See section on Measurement 

Process.) However, because measurements were 

made at various times throughout the day at each 

location and in summer in some areas and in 

winter in others, height and weight measurements were not standardized with regard to 

diurnal and seasonal variation. Weights vary 

somewhat between winter and summer and differ 

slightly depending on recency of food and water 

intake. 

In any study which focuses on the growth of 

children, it is important that the age of each 

child be correctly recorded. Age data for children of the United States are based on bhth 

certificates. Age is determined by the difference 

between date of interview and date of birth as 

shown on the birth certificate and is used in 

the present analysis. Birth certificates were 

obtained for more than 95 percent of the examined sample children. For the remaining 

children, age was used as stated by the parent. 

Measurement Process 

Control of the measurement process so 

as to minimize nonsampling error (or me&­

urement error) was a matter to which considerable effort was directed. This included steps 

related to the accuracy of measuring equipment, 

to the training and retraining of examining personnel, to the procedures established for the 

measurement process and the fidelity with which 

they are carried out, and to the minimizing of 

recording or transcribing error. 

Weight was recorded-using a highly accurate, 

self-balancing, automatic printing set of scales. 

The examinee stood on the scales, wearing only 

the standard examining uniform, less robe. The 

“Body Measurement” page of the examinee’s case 

record was inserted in the slot at the front of 

the scale, and the survey technician pressed a 

button which recorded the weight directly onto 

the record form. Thus, the possibility y of an error 

in the first step of recording the weight on the 

record form was avoided. The later transcription 

of the recorded weight in the data preparation 

and processing operation was susceptible to and 

was subjected to sample quality control verification. Weights were recorded to the nearest 

0.5 pounds, and this was transformed within the 

computer into kilograms (and decimals thereof) 

to the nearest gram. 

For measuring standing height, a special 

device involving a horizontal platform on which 

the examinee stood and an attached vertical bar 

on which was fastened a moveable horizontal arm 

was used. A camera capable of producing a 

finished print in a matter of seconds was attached 

to the moveable arm. The examinee, wearing 

the standard uniform, including socks but without 

shoes, was positioned on the platform with his 

back and heels against the upright bar of the 

height scale. He was then urged to stand erect 

(“Stand up straight” or “Stand up tall”). With 

feet together and head in an approximation of the 

3 
Frankfort plane ~%ook straight ahead”), the 

moveable arm was lowered to fit snugly against 

the top of the examinee’s head. An adhesive 

label bearing the examinee’s case number was 

fastened to the vertical bar at a point where the 

camera focus included both it and the pointer 

arrow which designated the height. The technician 

pressed the camera shutter button and photographed the scale reading and case number. The 

finished print was removed from the camera 

seconds later and was made a part of the survey 

record of. the examination. Again with this procedure, the possibility of an error in the first 

step of recording was avoided. The later transcription of the photographed scale reading in 

the data preparation and processing operation 

was subjected to sample verification. Height was 

recorded to the nearest millimeter. 

Considerable effort was directed to insuring 

that the prescribed procedures were followed in 

making the various body measurements, including 

standing height and weight. These were always 

made by designated members of the survey team. 

The several technicians who took X-rays also 

did audiometric testing and carried out various 

parts of the examination. During tie 3 Years of 

the survey, there was no personnel turnover in 

the technician category, and the total number of 

different individuals who did the examining was 

only four. At any single time there were two 

technicians in each of the two Mobile Examination Centers which operated concurrently in 

diffe$ent locations. All of these technicians were 

trained by and were under the technical supervision of the medical advisors to the Health 

Examination Survey. Written manuals of procedure spelled out the precise way in which the 

measurement process was tp be carried out, and 

the medical advisor visited the Mobile Examination Center periodically to observe the process. At each new location, or approximately each 

month, the first day of operations was devoted 

to retraining. No sample children were seen on 

that day, but a number of examinations on nonsample children of the same age were made. 

During the training operation each of the two 

technicians would measure the same subject 

and compare their results to increase standardization of procedures. With respect to some of 

the tidy measurements, this and other replication activities were an important part of the 

effort to control measurement error. With respect to standing height and weight, the measures 

taken to mechanize the recording were regarded 

as sufficient to obtain this same end. 

At every new location certain established 

procedures to recalibrate the measuring devices 

were carried out. A set of standard weights was 

used to verify the accuracy of the weight scaleE:. 

Combinations of the separate weights were placed 

on the scales, and recording accuracy was verified at 25-pound intervals from O to 150 poundw 

Whenever any discrepancy was detected, the 

necessary adjustment was made. At the beginning and end of each stand a systematic check 

was also made of the equipment for measuring 

height. It is believed that these checking and 

calibration procedures safeguarded the survey 

agtiinst the introduction of measurement errcr 

through equipment malfunction. 

It was noted that weights were all recorded 

with examinees wearing the standard survey 

uniforms. While four different sizes were used, 

they varied in weight from. only .11 to .30 kilcgrams. The amount of difference from nuc e 

weights, even though always in one direction, !s 

regarded as negligible in data where the precj ­

sion of the original measurement is only to tl e 

nearest .23 kilograms. The effect of the socks 

worn for the measurement of height is likewiE e 

negligible. 

While no direct quantitative assessment can 

be given of the effect of examiner-related mea+ 

urement error on the height data, there are 

some relevant data from another Health ExarrLination Survey using similar procedures. The 

data suggest that the median absolute interexaminer and intraexaminer differences found in the 

replication of height measurements of the same 

subjects amounted to only about 3 or 4 mill;­

meters. In the analysis of the data, heights ha~pe 

generally been considered in 5-centimeter group 3. 

Since the variability in the measurements due :0 

examiner error seems equally likely to be in 

either direction and since the magnitude of that 

error is small relative to the measurement 

itself and to the range included in the grouped 

frequencies, it is believed that the effect on the 

resultant means, percentiles, and the like can he 

disregarded.

CHILDREN OF INDIA 

General 

Data on children of India are taken from a 

larger cross-sectional survey carried out in 

India by the Indian Council on Medical Research. 

The study, “Growth and Physical Development 

of Indian Children,” was planned and executed, 

insofar as data collection is concerned, during 

the period 1956-65.. The principal purpose of the 

study was to establish standards of reference on 

growth and development of Indian children. The 

Indian Council on Medical Research appointed a 

Working Party to evolve uniform procedures for 

the conduct of studies and the collection, analysis, tabulation, and interpretation of the data 

obtained. The survey was made on a country-wide 

basis and covered the entire age range from 

birth to 21 years of age. The “National Center 

for Health Statistics assisted in the process of 

tabulating and analyzing the collected data. This 

report presents only the data on standing height 

and weight of children aged 6 through 11 years. 

Sample Design 

Data were collected from a representative 

sample covering all socioeconomic groups and 

religions and as many areas of the country as 

possible. Uniform instructions were prepared to 

govern the procedures of sample selection in the 

various parts of the country, The original sample 

proportion was set at ‘one in a thousand. The size 

of the sample was fixed at 200,000 children. Of 

the total sample children, about 44,000 children 

aged 6 through 11 were examined. Slightly more 

than half were boys, and there were approximately the same number of children at each 

single year of age. 

The sample was stratified on a rural-urban 

axis. Three-eighths of the total sample were 

from rural areas, and the balance was from urban 

areas. A stratified random sampling design was 

adopted to select the rural sample. Further 

stratification was introduced for the urban areas, 

so that specified numbers of the sample were 

drawn from groups of towns or cities of various 

sizes. An attempt was made to insure that the 

nonschool population was properly represented 

along with the in-school population. Consideration was also given to appropriate representation from various socioeconomic groups in the 

population. Thus, for example, schools were 

stratified according to the different socioeconomic groups which they tend to serve, and the 

required sample was drawn after the stratification, taking into account the relative numbers 

of persons in the different strata. 

It was decided to limit the sample to persons 

who were residents of the area, in the sense that 

they had spent the major part of their life there. 

In addition the sample excluded certain children 

classed as abnormal. The instructions for this 

exclusion read as follows: 

“Only those children showing the following 

signs or symptoms should be eliminated from 

the study: 

(a)	 Those, who have been bedridden for 

more than 15 days, during the six 

months preceding the time of examination and those who suffered from any 

ailment in the preceding one month. 

(b) Those with physical deformities or clinical evidence of endocrine dysfunction. 

(c) Those with any chronic systemic diseases of the organs as listed in the PYO 

forma, and 

(d) Those showing the following signs of 

malnutrition, e.g., Bitot’s spots, keratomalacia, glossitis or angular stomatitis, marked anaemia and stigmata 

of past rickets. 

One need not eliminate children with chronic 

conjunctivitis, trachoma, history of tonsillitis, 

skin infections, etc., but such conditions, when 

observed may be noted clearly under the remark~ 

column before the measurements are obtained.” 

Plan of Survey Operation 

The Indian Medical Research Council established seven different units in different parts of 

5 
the country to carry out the survey. The units 

were located at specified universities, medical 

colleges, and laboratories. Ten survey teams 

performed the examinations in the seven areas, 

each team examining approximately 20,000 persons for the total sample. Each team had one 

medical officer for a clinical appraisal of the 

child, one anthropologist for obtaining the measurements, one statistical assistant to help in the 

selection of the sample, one social worker, and 

an attendant. 

The social worker was to ascertain the 

correct age of the child and to assess the 

socioeconomic status and living conditions. It 

was recognized that assessment of correct age 

would be difficult although it was extremely 

important to the usefulness of the data. The 

Working Party recommended that, through tactful interview with parents, attempts be made to 

check on the age of the children in a subsample 

of at least 5 to 10 percent of the examinees. For 

this check reliance should be placed only on 

“documentary evidence like authentic home records, horoscopes, baptismal certificates, birth 

registers maintained at hospitals or municipal 

or local board offices, etc.” Reliance was not to 

be placed on school records or on oral statements 

for the correct age. 

The sample design as developed by the 

Working Party has already been described. The 

plan of operation called for the statistician or 

statistical assistant attached to each of the 

teams to actually execute the design and select 

the sample. He was instructed to “see that the 

sample is not affected by conscious or unconscious bias” and to “make it as representative 

as possible of the population” from which it was 

drawn. 

Verification of age was actually obtained 

for more than one-fourth of the cases in the 6-11 

age range. Separate analysis of these ‘‘age-veri. 

fied” cases showed that the means for both height 

and weight were almost identical with those for 

the total sample, for both males and females, 

and for each year of age. It is interesting to note 

that the standard deviations of these means for 

the age-verified children tended to be somewhat lower than for the total sample. 

Measurement Process 

The importance of standardization in tht: 

measurement process was clearly recognized, 

Persons who were to make the measurement~ 

were trained together at central points, and the 

training included replicate measurements to as. 

sess the range of personal error of each worker. 

From time to time instruments used were checkec~ 

for accuracy. Measurements were made with 

minimal clothing. 

For the measurement of standing height tht 

child was made to stand (with heels together anc 

without shoes) so” that the shoulders, buttocks, 

and heels touched the vertical upright portion 01’ 

the scales. The individual looked straight forwarc 

so that the line drawn from the tragus to the 

inferior orbital margin was in a plane parallel 

with the floor. At the time of measuring he wa5 

asked to take a deep breath and make himself 

as tall as possible without raising his heels. The 

height was recorded when the anthropometer 

beam was brought down firmly on the vertex. 

When necessary, combs, ribbons, clasps, or 

other impediments were removed from girls’ 

hair prior to this procedure. 

For the measurement of weight a beam type 

scale was used. Its accuracy was checked daily 

by the use of standard weights. Younger children 

of both sexes and boys of all ages were weighecl 

in the minimum of clothing possible, and the 

weights may be taken to approximate nude 

weights. In the case of older girls, four or five 

of the most common types and sizes of dresses 

were weighed in order to determine standard 

adjustment factors. An appropriate allowance 

was made for the clothing, depending upon the 

kind worn. Thus, these weights as recorded may 

also be taken to approximate nude weights. 

CHILDREN OF THE UNITED ARAB 

REPUBLIC (EGYPT) 

General 

Data on children of Egypt are taken from a 

larger cross-sectional national school health 

survey carried out in each of the Egyptian 

6 
governates in 1962 and 1963. The survey was 

jointly planned and conducted by the Egyptian 

Central Statistical Committee and the Ministry 

of Public Health. It was larger in the sense that 

it covered the age range from 6through 18 years. 

The population surveyed by representative sampling was that of children aged 6-18 who were 

enrolled in public primary, preparatory, and 

secondary schools.4 

One objective of the survey was to provide 

information on certain school-age health problems such as skin diseases, dental diseases, and 

urinary and intestinal parasitic infections. Another objective was to provide standards and 

norms of growth in height and weight. The 

information was needed not only for school health 

program planning but for medical and industrial 

uses as well. Pediatricians and other physicians 

had been obliged to use European or American 

standards of growth since data for a, national 

sample of Egyptian —.. children had never been obtained. Two limited studies in Cairo in 1956 and 

in Alexandria in 1959 indicated that the norms 

for children of Egypt did differ from those for 

children of Europe and America, but that there 

had never been a study on a national representative sample. 

The National Center for Health Statistics 

assisted in tabulating and analyzing the collected 

data. This report presents only the data on standing height and weight for children aged 6 through 

11 years. 

Plan of Survey Operation 

A survey committee composed of various 

medical and health specialists was organized in 

the Ministry of Health and was responsible for 

the planning and conduct of the survey. The 

committee supervised the field work, and its 

members and officials in the Department of 

School Health and the Department of Statistics 

(both of the Ministry of Public Health) periodically visited the field teams during the survey. 

The committee devised the survey forms and the 

instruction manuals. There was at least one 

field team in each governate. Each field team 

was composed of a physician, a dermatologist, an 

oculist, a dentist, twp laboratory technicians, 

two “health visitors ,“b attendants, and a driver. 

Prior to the survey all members of all field 

teams attended a training course in Cairo and 

also participated in pretesting the survey form. 

The teams then visited the chosen schools and 

examined the sample pupils. They operated under 

the direct supervision of the Assistant Director 

for School Health of the Governate Health Administration. 

The sample selected was a stratified proportionate random sample of school children 

drawn from a frame maintained in the Ministry 

of Education of all primary, preparatory, and 

secondary public schools in all governates of the 

UAR. The sample selected included over 100,000 

pupils in the age range from 6 through 11 years. 

The sample was shown to be representative in 

respect to age, sex, type and place of education, 

and the rural-urban distribution of the universe 

in each of the governates. Slightly over one-fifth 

of the sample was not examined, because of 

absenteeism on the day of the visit. The high 

absentee rate has been attributed to causes not 

mainly medical. The period during which much 

of the survey was carried out (April-June) 

coincides with the harvest season, the cotton-leaf 

worm campaign in the rural areas, and the preexamination period at the end of the school year. 

The sample examined is assumed to be fairly 

representative of the universe from which it was 

selected. It should be noted that this is a universe 

of children enrolled in public schools. The 

exclusion of children attending private schools 

may be numerically insignificant. There is, 

however, variation by governate in the proportion of the total child population enrolled in 

public schools despite compulsory education laws 

applicable to these ages. In part the variation 

reflects the differing situations with respect to 

school capacities for enrollments. It has been 

estimated that the proportion of children 

through 11 years enrolled in school may vary 

by governate from a low of about 80 percent 

to well over 90 percent. This should be kept in

mind when relating findings of the school survey 

to the total population aged 6-11 years. 

The age recorded in the survey was obtained 

from the school records, which showed the age 

as stated on the birth certificate. 

The measurements of height and weight 

were made by the two “health visitors” under 

the direct supervision of the pnysician member 

of the team. Height was recorded to the nearest 

centimeter. For the height measurement the 

pupil stood erect and barefooted. The head 

STATEMENT OF 

CHILDREN OF THE UNITED STATES 

Mean Height and weight by Sex and Age 

Height.—The mean heights of U.S. children 

aged 6 through 11 years increased quite regularly 

by about 4 or 5 percent for both boys and girls at 

each successive year of age. At ages 6 and 7, boys 

were on the average only about 1 cm. taller than 

girls. The means were identical for the two sexes 

at age 9, and at ages 10 and 11 girls were on the 

average about 1 or 2 ems. taller than boys. 

At age 6 boys had a mean height of 118,6 ems. 

The mean increased by about 5 or 6 ems. for each 

single year of age until it reached 145.7 ems. at 

age 11. Girls at age 6 had a mean height of 117.8 

ems.; the mean increased about 6 or 7 ems. for 

each single year of age until it reached a mean of 

147.6 at age 11 (table 1). It is important to remember that these increments are true of the means of 

groups of children. Individual children vary in 

their rates of growth, and the limitations of 

cross-sectional data, already noted, must be 

recognized in considering year-to-year changes. 

It is apparent from the foregoing that the 

graphs for mean height for this populaticsn are very 

nearly straight lines. The question of the appropriate curve to properly fit human growth data is 

much more complicated than is seen by examining 

this limited age group. The subject has been 

studied intensively most recently by Pineau, 5 who 

begins with a review of the related work done in 

many countries and proceeds to demonstrate that 

the appropriate curve of human growth is formed 

by joining two S curves. During the short period of 

marker was kept parallel to the floor and wtts 

made to touch the head tightly. The reading wus 

to be rechecked before recording. Weight wt:s 

taken with the pupil clad only in underwear and 

barefooted and was recorded, after the “heal h 

vistor” rechecked the reading, rounded to tl e 

nearest kilogram. The pupil was to have urinated 

prior to the recording. The height and weight 

scales used were regularly checked by the field 

team members to insure accuracy and levelin~;.

years from age 6 to 11, however, a period just 

preceding and partly including the second point of 

inflection of the combined curve of Pineau, the rate 

of curvature is very slight and the curve in this 

segment is roughly linear. Since the presently 

available data on U.S. children include only a 

limited portion of the total period of growth and 

development, no attempt has been made to fit a 

curve to the data. Figure 1 shows the broken lines 

(boys and girls) resulting from connecting the 

means for each year of age.

Weight. —Mean weights by sex and age showed 

a generally similar pattern, but there were some 

differences, The mean weights for boys at ages 6 

and 7 were only slightly above those for girls 

(about 0.5 kgs.). The means for weight, as for 

height, at ages 8 and 9 were intermediate and 

quite close together. The main difference in the 

comparison is that at ages 10 and 11 girls had 

mean weights that exceeded those of boys of 

similar ages by a relatively greater amount (about 

1,5 kgs,)-relative to the advantages of boys aged 

6 and 7—than was true for the means of height. 

Another way of stating the same difference is that 

the graph of the changes in mean weight of girls is 

less nearly linear than either the graph for mean 

weight of boys or the graphs for mean height of 

both boys and girls (figs. 1 and 2). 

Standard Deviations of Height and 

Weight Data 

Standard deviations of height ranged from 5.3 

ems. to 7.0 for bays. The lowest value was for the 

6-year-old boys, and the figures increased regularly throughout the age range. Corresponding 

values for girls displayed the same pattern of increase with increasing age (from 5.5 ems. at age 

6 to 7,8 at age 11), but were slightly higher at 

ever y year of age than the standard deviations for 

IXlys. 

Essentially the same age and sex differences 

were seen in the standard deviations of weight. 

Here again, as with the height, the dispersion of 

the distribution was a little greater for girls than 

it was for boys. Also, with only one exception, the 

standard deviations increased as age increased 

(table 1). 

Standard deviations for weight data were much 

larger relative to the measured weights than were 

standard deviations for height data relative to the 

measured heights. The magnitudes of the standard 

deviations for height were about 4 or 5 percent of 

the mean values; for weight the standard deviations 

were from 16 to 23 percent of the means. These 

figures are, of course, the coefficients of variation. Thus the frequency distributions of the 

weights are less compact and are spread out more 

widely.

Percent Distributions 

Percent distributions for height and weight 

are presented by sex and single years of age in 

tables 2 and 3. The tables show the percent of the 

total population of specified sex and age that falls 

within each of the designated height or weight 

groups, or ranges of measurement. 

The general pattern displayed by the height 

distributions is seen more readily in figure 3. 

Here it is apparent that the shape of the distributions for each age forms a more or less normal 

curve pattern. At the older ages in this range, the 

curves become less peaked, a fact that had already 

been implied by the increase of the standard deviations with age. 

It is apparent from either the graphs or the 

tables that the modal group of the distribution increased by about one group with each year of increased age. The ranges of the distributions have 

some overlap for any two of these ages, the degree 

of overlap decreasing regularly as the two ages are 

farther apart. Thus, only abut 5 percent of the 

11- year-old boys were short enough to fall in the 

range which included essentially all of the 6- yearold boys and over 95 percent of the 7- year- olds.

As shown in figure 4, distributions of the peaked and the range more limited relative to the

‘The medians for height of lmth boys and girls 

were almost identical with the means. This was 

true for each single year of age 6 through 11. For 

weight, however, means and medians were almost 

the same at age 6, but at the older ages the means 

were higher—reflecting the fact that more extreme values were above the median than below it. 

Medians (50th percentile) are shown in figure

Standard Errors of the Means 

The values presented for height and weight 

of U.S. children have been obtained through a survey which was based on a probability sample. 

Because this survey used a complex, multistage, 

clustered design, the computation of statistic 

measures such as the standard error of the mean 

presents certain problems. The method used to

The standard errors of the means for heights 

ranged, by single year of age, from 0.24 ems. to 

0.44 for boys and from 0.18 to 0.33 for girls. For 

weight the standard errors of the mean fell between 

0.15 and 0.43 kgs. for boys and between 0.21 and 

0.41 kgs. for girls. These standard errors include 

some effects of residual measurement error as 

well as the sampling error in the data. Values are 

small relative to the measurements.

the specified sex-age group with measurements 

falling within that range. Figures 8 and 9 display 

the same data graphically. It can be seen that the 

patterns are much the same for boys and girls, 

but that the two distributions for height present a 

somewhat clifferent pattern from that seen for the 

weight. 

The distributions for heights were similar at 

each year of age for both boys and girls. The pattern was that of a normal curve, and the modal 

group of the distribution increased by one interval with each increase in age. The curves shown 

for the distributions of weight appeared to be 

markedly more peaked for the younger ages and 

did not show the same upward shift of the modal 

groups with each increase in age. In part this may 

reflect the size of the grouping used for weight, 

but it also reflects the more compact distribution 

and more limited range of weights in the younger 

portion of the population at these ages. These 

changes in the distributions are implied by the increases in the coefficients of variation from 0.16 

for both boys and girls at age 6 to 0.24 for boys 

and 0.21 for girls at age 11.

The medians (or 50th percentile) for height of 

boys and girls at each year of age 6 through 11 was 

very nearly identical with the means. The medians

not as closely so. For boys aged 6-8 the mean

the corresponding median, while for boys aged 

9-11 and for girls aged 6-11 the means were

For girls the mean was 113.5 ems. lower than for 

boys by less than a centimeter. The very slight 

difference in the means by sex decreased further 

for each year of age as the means increased. Those 

for girls increased slightly faster than for boys 

until at age 10 girls were only 0.1 cm. below the 

boys. By age 11 the mean height of girls was 1 cm.

Weight. — Like height, the mean weights for 

both boys and girls were very close together at 

ages 6 through 11. Boys were slightly heavier at 

ages 6-8, but this advantage disappeared by age 9, 

and by age 11 girls outweighed boys on the average. 

The weights rose rather sharply for each single 

year of age, from 20.3 kgs. to 30.3 for boys and 

from 20.1 kgs. to 31.1 for girls (table 9 and fig.

Standard Deviations of Height and 

Weight Data 

The standard deviations of the means for 

both height and weight of UAR children are shown 

in table 9 for each year of age. Standard deviations 

for both height and weight were slightly higher for 

girls than for boys, and they increased somewhat 

irregularly for both sexes throughout the age 

range. The standard deviations for weight were 

relatively higher than for height. The coefficients 

of variation were between 5 and 6 percent for 

height and around 15 to 18 percent for weight. 

Percent Distribution 

Percent distribution for various height and 

weight groups are shown by sex and single year of 

age in tables 10 and 11. Figures 13 and 14 make it 

apparent that each of the distributions approximates a normal curve, with heights showing less 

departure from normality than the weights. The 

modal group for height increased regularly by one 

5-centimeter classification for each year of age. 

Distributions for weight are more peaked, 

particularly at 6 and 7 years of age. At the older 

ages the distributions are somewhat more skewed 

towards the higher values. 

Selected Percentiles of Height and Weight 

Distributions 

The 10th, 25th, 50th, 75th, and 90th percentiles of the distributions of height and weight are 

shown in table 12 and figure 15. The value of 

height or weight that divided the lowest and the 

highest 10 percent—for example, 10th and 90th 

percentiles-of the population from the others are 

shown separately by sex. It is seen that the range 

at each age was quite great. Thus the top 10 percent of both boys and girls aged 6 years had 

weights that were higher on the average than the 

~	 bo~om 10 percent o~the n-year-old;. The 90th 

percentile for height of 6-year-olds was about the 

same as the 10th percentile for the 10-year-olds. 

The maximum interdecile range (90th minus 10th 

percentile) increased steadily throughout the age 

range. The range for height increased _&omabout

that sex, like age, had relatively little effect on 

this relationship. 

The relation between height and weight is 

readily seen in figure 16. The pattern is remarkably similar for boys and girls. The values shown 

in the graph are the mean weights for each of the 

5-centimeter height groupings, plotted at the midpoint of the intervals. The relation between the 

two variables is nearly linear for the middle range 

of heights shown, but for the full range the Mnear 

regression line shown does not give a particularly 

good fit. The same data are shown in figure 17, 

where the vertical axis is on a logarithmic scale. 

Here the lineari~ indicates that the proportionate 

increases in weight with successive increases in 

height are very nearly equal. 

It was noted that for specific heights of children 6-11 years, weight was relatively independent of year of age. Table 16 shows this for the 

weight-height ratios. Also shown is the very clear 

increase in the ratios (expressed as grams weight

per centimeter height) with increasing height. 

The range of the ratios was from less than 200 to 

more than 300 grams per centimeter. The ratio 

increased fairly regularly with increasing height. 

Figure 18 displays this separately for boys and 

girls although the patterns for the two sexes were 

quite similar. The graph is very nearly linear, 

except for the exmeme values at both ends of the 

range. Here, again, it is. seen that the successive 

height increases produced proportionate weight 

increases since the weight values were plotted on 

a logarithmic scale. 

Table 17 shows not only the mean weights for 

successive height intervals but also the values for 

five selected percentiles. These are plotted on 

semilogarithmic scale in figure 19. The patterns 

for boys and girls are remarkably similar. The 

values for each of the percentiles showed consistent increases in weight with increases in height, 

and the proportionate increases were very nearly 

constant. It appears from these data that the mean

weight of each successively greater height group 

increased by approximately 10 percent. Since 

these are 5-centimeter height groups, it might be 

restated as follows: in the range of heights observed for both boys and girls, each successive increase of a centimeter of height was associated on 

the average with an increase of roughly 2 percent 

in the weight. This was generally true of each of 

the various parameters examined, not only the 

mean and the median but the 10th, 25th, 75th, and 

90th percentiles as well. It was generally true for 

both boys and girls. 

CHILDREN OF INDIA. 

Coefficients of correlation between height and 

weight were computed for each of the 12 sex-age 

groups and all fell between 0.69 and 0.77. 

The increase in weight with increase in height 

was examined separately by sex and single year of 

age. The pattern of the height-weight relationship

was almost identical for each of the ages and for 

both sexes. The only notable exception was in tl e 

pattern for n-year-old boys. Here, taking age into 

account did make some difference. Thus, for ex -

ample, an 11-year-old who fell in the height 

group of 115.0 -119.9 ems. and who weighed abou; 

19 kgs. would be at about the 10th percentile of 

the weight distribution for 11-year-old boys of 

this height, but he would be at about the 50th percentile for the corresponding distribution of all 

boys 6-11 years. A boy at any of the ages 6 through 

10 would be at about the median of both the distribution for his particular age and the distribution 

for boys 6-11 years. Similarly, a boy of the same 

height (115.0 -119.9 ems.) who weighed 21 kgs. 

would be at about the mean or median of the weight 

distribution for his specific year of age if he was 

11 years old, but he would beat the 90th percentile 

if he was any one of the ages from 6 through 10 

years. The same kinds of examples could be given 

for boys in the height groups 120.0 -124.9 ems. and

125.0 -129.9 ems., and they would show the same 

exception status as for the 11-year-old. 

Table 17 and figure 20 show the means and 

selected percentiles of the distribution of weight 

cross-classified by height for all boys and all 

girls, respectively, at ages 6-11 combined. Because of the relative inappropriateness of these 

combined data for 11-year-old boys in some instances, separate data for them are shown in 

table A. 

As seen from figure 20 (where the vertical 

scale is logarithmic) the proportionate increase in 

weight with each increase in height was very nearly 

constant, about 10 percent. This was true of the 

mean and generally true of each of the-selected 

percentile values shown. 

CHILDREN OF THE UNITED ARAB 

REPUBLIC (EGYPT) 

There is a marked, direct correlation between weight and height of children at ages 6 

through 11 years. Those children who were less 

than 115.0 ems, in height had a mean weight of less 

than 20 kgs., while those whose height was more 

than 150.0 cms. had a mean weight more than twice 

this figure. The increase was roughly about the 

same proportion with each successive height 

group-about 10 percent increase. Table 18 shows 

these successive increases separately for boys 

and girls aged 6-11 years. Figure 21 shows this for 

selected percentiles. 

The relationship was examined separately for 

each individual year of age. Although the heightweight relationship was quite similar for each age, 

there appeared to be some age factor present in 

the relationship, although the effect was not a 

marked one. Thus, boys in a particular height 

group tended to have a slightly greater mean weight 

as age increased. For example, for boys who were 

between 120.0 and 124.9 ems. in height, the mean 

weights (in kgs.) at successive ages 6 through 11 

years were as follows: 22.9,22.9,23.3,23.7, 24.0, 

and 26.3. Table B shows mean weights by sex for 

specified height groups. The relationship between 

height and weight is seen clearly by examing the 

weight-height ratios shown in table 19. Here too, 

it is evident that the ratio mean weight to height 

not only increased with increasing height but it 

tended to be higher for children at the older ages 

even when height is held constant.

COMPARISON OF DATA FOR THE THREE COUNTRIES


ABSC)LUTE VALUES AND THEIR 

DISTRIBUTIONS 

The data for height and for weight of children 

aged 6-11 years for the three countries studied 

here present three cIearly distinct levels. The 

U.S. children had mean heights and weights considerably above those of the Indian children, while 

the UAR children had means that were intermediate (tables 20 and 21; fig. 22). 

Indian children had mean heights which fell 

about 9 percent below those of children of the 

United States at every age. Mean heights of UAR 

children were intermediate-nearer but above the 

Indian level and about 4 percent below the U.S. 

means at age 6, with the difference increasing to 

where they were about 7 percent below at age 11. 

Stated another way, the means for heights of Indian 

children at every age from 6 through 11 years fell 

below the comparable U.S. means by nearly two 

standard deviations. UAR children aged 7 through 

11 fell a little more than one standard deviation 

below the means for the U.S. children; those aged 

6 years were a little closer to their U.S. counterparts. 

The comparisons with respect to mean weights 

were somewhat similar. Means for U.S. children 

were considerably above those for the other two 

countries, those for UAR children were intermediate, and for children of India they were lowest 

at each single year of age. UAR children had mean 

weights which were a little less than one standard 

deviation below the means for U.S. children. 

Means for Indian children fell about 1!4standard 

deviations below those for U.S. children at each 

single year of age. In terms of the relative magnitude of the weight means, Indian children were 

about 30 percent and UAR children were roughly 10 

to 20 percent below U.S. children. 

In comparing the heights of children of the 

United States, India, and the United Arab Republic, 

it is interesting to look at some of the available 

data concerning the average heights of children of 

the United States at an earlier period. It is known 

that heights of children of the United States have 

increased during the past half century. Wle no 

truly comparable data are available from any earlier period, there are a number of stu~es7 of selected groups of children that demonstrate this increase. Table 23 shows ‘the mean heights of U.S. 

children aged 6 through 11 years at four different 

time periods based on the best available data. The 

means for the U.S. children for the period about 

60 years earlier were only slightly lower than the 

current data for UAR children and slightly higher 

than those for Indian children. 

The patterns displayed by the distributions of 

both height and weight show many similarities 

among the three countries. All of the curves tend 

towards a normal dis~ibution. For the most part 

the standard deviations for height and for weight 

increased from year to year. In the case of weight, 

but less so for height, there was usually some increase in the coefficient of variation (the standard 

deviations relative to the mean) with age. In all 

three countries the weights displayed far more 

relative variability the coefficients of variation 

for the weights were about 3 to 4 times as great as 

those for height in each country and for each age 

and sex group. The coefficients of variation for 

height (but not weight) of, Indian children tended to 

be somewhat higher than in the other two countries. 

This reflects the lower means for height of Indian 

children being accompanied by relatively high 

standard deviations of the heights. The coefficients 

of variation for height were between 5 and 6 percent for the U.S. and UAR children, and mostly between 7 and 8 percent for Indian children. The 

coefficients of variation for weight range between 15 and 25 percent in all three countries. 

While the mean weights in the United States were 

clearly higher than in the other two countries, 

the standard deviations of the mean weights were 

correspondingly higher in the United States. 

Comparison of selected percentiles of the 

distributions of height and weight showed clearly 

the fact of the three different levels of values for. 

the three countries. The 25th, 50th, and75thpercentiles at each year of age for both boys and girls 

were highest for the United States, lowest for India, 

and intermediate for Egypt (table 22). In each of the 

comparisons the 25th percentile for U.S. children 

was higher than the 75th percentile for Indian children. fi 10 of the 12 comparisons the 25th percentile for U.S. children was above the 50th (or 

median) for UAR children.

INTERRELATIONSHIP BETWEEN 

HEIGHT, WEIGHT, AGE, 

AND SEX 

The variaMlity of height and weight with age 

and with sex is very nearly the same in each of 

the three countries, although the overall levels 

at which the means fall do differ, as seen above. 

There was a steady, nearly linear, increase in 

height with increasing age. Weight also increased 

with age, but showed some greater variability. 

Both height and weight showed increases in the 

standard deviations with increasing age throughout the age range as has been noted. Within each 

of the three countries, the means for boys and 

girls were quite close together, and the pattern 

was for boys of all countries to be slightly taller 

and slightly heavier than the girls in the early part 

of the age range and for girls to catch up and/or 

surpass the boys by at least age 11. The point at 

which the girls surpassed the boys varied a little 

among the three countries, with the event occurring earliest for U.S, children. 

In each country weight was highly correlated 

with height. As height increased, weight increased 

both absolutely and relatively. In other words, wirh 

each increase in 5-centimeter height groups, not 

only did the mean weight increase but the ratio of 

weight to height also increased. The relative 

weight (kgs. of weight per ems. of height) W6.S 

slightly different among the three countries, whh 

the United States having the highest relathe 

weights and India the lowest. The pattern WE.S 

essentially the same, however, in all three coLw,­

tries.
