SYNOPSIS

An anthropometric survey of military personnel of the ArmedForces of Thailand was conducted between October 1962 and March1963. The survey was sponsored by the Advanced Research ProjectsAgency, Washington, D. C. and was authorized by ARPA Memorandumof July 27, 1962, Subject: Anthropometry Research in SoutheastAsia.

Body measurements were obtained on a total series of 2,950men, consisting of 2,010 of the Royal Thai Army, 610 of the RoyalThai Marine Corps and 330 of the Royal Thai Air Force. Fifty-twomeasurements were made on each individual. The anthropometricdata have been analyzed and are presented in this report in theform of statistical values.

It was found that the average height and weight of Thaimilitary personnel were equivalent to the 5th percentile valuesof height and weight for United States soldiers, The Thai soldieris about four inches shorter in stature and 30 pounds lighter inweight than the average United States soldier.

The results of the survey, which provide information on thebody size of Thai military personnel, may be utilized in theengineering design and sizing of clothing and equipment intendedfor use by the Royal Thai Armed Forces.

1. INTRODUCTION

a. Purpose

Anthropometric data constitute a basic requisite for definingthe elements of body size in the human engineering of man-equipmentsystems. Effective human engineering requires the use of data on thespecific population for which the equipment is intended. Since noadequate data existed on the Royal Thai Armed Forces, an anthropometricsurvey was conducted to collect data on the body dimensions of a largesample of this military population. Analysis of these data has made itpossible to define the range and variation in body size to be expectedin the military personnel of Thailand.

The results of this survey should be utilized in all areas ofresearch and development where detailed knowledge of Thai body sizesand proportions are necessary. Anthropometric data on Thai militarypersonnel are of primary application in the engineering design ofmilitary equipment for the Royal Thai Armed Forces. The furtherapplication of this information to problems of design, sizing and fitof military clothing and personal equipment will result in increasedefficiency, performance and comfort. Data on the range and variationof body size in the user population thus may be employed in theimprovement of size systems and tariffing in order to achieve increasedlogistic efficiency and economy of supply.

b. Summary

An anthropometric survey of military personnel of Thailand wascarried out between October 1962 and March 1963. A total series of2,950 was measured, including 2,010 men of the Royal Thai Army, 610 menof the Royal Thai Marine Corps and 330 men of the Royal Thai Air Force.Fifty-two body measurements were made on each individual. The resultsof the survey, together with analyses of the data, are presented inthis report.

The survey was sponsored by the Advanced Research Projects Agency(ARP4) of the United States Department of Defense. The data collectionin Thailand was carried out under the authority of the Ministry ofDefense of Thailand. The project was supported by the Military Researchand Development Center (MRDC), a joint United States-Thailand researchand development activity in Bangkok. The survey was directed by Mr.Robert M. White, Head, Anthropology Laboratory, United States ArmyNatick Laboratories, Natick, Massachusetts. During his tour of duty inThailand, Mr. White was attached to the ARPA Research and DevelopmentField Unit, the United States element of the Military Research andDevelopment Center in Bangkok.

2. PROCEDURES

a. Planning and Organization

Planning for the ahthropometric survey of Thailand was carriedout at the Military Research and Development Center, Bangkok inSeptember 1962. The first consideration to be taken up was the sizeof the sample of men to be measured. It was estimated that a seriesof between 3,000 and 3,500 men would serve as an adequate sampling ofthe Armed Forces of Thailand. In order to provide representation fromall services in the Armed Forces, it was planned that a large samplewould be drawn from the Royal Thai Army, with smaller samples from theRoyal Thai Navy and Royal Thai Air Force. Subsequently, a decisionwas made that Royal Thai Marine Corps personnel would be measured asrepresentatives of the Navy.

During the planning for the survey, it was stipulated that men ofall age groups would be included in order to cover the range ofmilitary personnel from young recruits to older veterans. It was alsoplanned that enlisted men of all ranks would be measured. Althoughthe plan for the survey did not include the measurement of officers,it was requested that a small sample of Air Force flying officers beobtained in order to provide information for application to flightclothing and equipment. With respect to the geographical location ofmilitary installations, it was planned that a large sample of Armypersonnel would be measured in the Bangkok area, while the Air Forceand Marine Corps samples would be measured at an Air Force base andat a Naval base near Bangkok. Subsequently, further samples of Armypersonnel were obtained at three installations in the east, north andsouth of Thailand.

A significant aspect in planning the anthropometric survey ofThailand was the provision that all of the measuring would be carriedout by Thai personnel who would be trained and supervised by a quali-fied physical anthropologist. This procedure proved to be entirelysatisfactory, not only since trained and experienced Americanpersonnel were not available, but also because the utilization of Thaipersonnel had the advantage of operational convenience. The fact thatthe first large-scale anthropometric survey of military personnel inSoutheast Asia was carried out by the Thais themselves is a source ofconsiderable satisfaction.

b. Measurements and Equipment

The initial step in setting up the measurement procedure wasthe selection of the body dimensions to be measured. A list ofapproximately fifty measurements was drawn up for consideration. Thesewere reviewed with Thai military personnel, and several additions were

5

Page 11: ANTHROPOMETRIC SURVEY OF THE ROYAL THAI ARMED FORCES · of July 27, 1962, Subject: Anthropometry Research in Southeast Asia. Body measurements were obtained on a total series of 2,950

made at the request of Thai Quartermaster officers. The fifty-two bodymeasurements finally agreed upon included dimensions of all parts ofthe body: weight, body lengths, breadths and circumferences, togetherwith selected measurements of the head and face, the hands and the feet.The measurements chosen fell into two general categories. Some of themeasurements are those of primary use in the design, sizing and gradingof clothing, while others are of importance in the design and sizing ofmilitary equipment from the standpoint of human engineering. Themeasurements are described in Section 4,a.

Following the choice of measurements to be taken, a data sheet wasprepared for use in recording the measurements and the background dataon each man. Although the data sheet was drawn up in English, acomplete Thai translation was provided. The data sheet was arranged sothat the recorded information subsequently could be transferred topunched cards for use in data processing. The data sheet is reproducedin Appendix A.

Standard anthropometric instruments were used throughout thesurvey. Anthropometers (calibrated metal measuring rods, 2 meters long)were used to measure stature and various body lengths; the anthropometersalso were utilized as large sliding calipers for body breadths and formeasurements of some arm and leg segments. Small sliding and spreadingcalipers were used for measurements of the head, face and hands. Bodycircumferences and surface measurements were taken with 2-meter steeltapes. Foot length, instep length and foot breadth were measured on aspecial foot board, while heel breadth was taken with sliding calipers.Weight was taken on spring platform scales, calibrated in kilograms.All of the body dimensions were measured and recorded in the metricsystem, with the measurements taken to the nearest millimeter.

c. Measuring Teams

A total of twelve measuring teams of five men each wereutilized during the anthropometric survey in Thailand. The first threeteams consisted of fifteen men of the First Infantry Division, RTA;these teams measured a large part of the Army sample in Bangkok. Twoadditional Army teams were made up of ten civilian clothing techniciansfrom the Quartermaster Corps, RTA. Another Army team consisted of fivemen supplied by the Medical Corps, RTA. Three teams of fifteen Marineswere trained and utilized for measuring Marine Corps personnel, andthree teams of fifteen Air Force men were trained and used to measureAir Force personnel.

Each measurer was provided with a recorder who wrote down themeasurements called out by the measurer, The recorders were furnishedby the installation where the measuring was carried out.

6

Page 12: ANTHROPOMETRIC SURVEY OF THE ROYAL THAI ARMED FORCES · of July 27, 1962, Subject: Anthropometry Research in Southeast Asia. Body measurements were obtained on a total series of 2,950

The basic measuring team consisted of five men: a team leaderand four measurers. The team leader was responsible for filling inthe background information on the data sheet and for recordingweight; it was also his assigned duty to maintain an even flow ofmen through the measuring line. Each of the four measurers wasresponsible for taking a block of related measurements.

In order to increase the number of men measured during a work-ing day, three measuring teams were used simultaneously at mostinstallations. It was thus possible to operate three processinglines and effectively triple the number of men measured per day.On the average, about 120 men were measured per working day.

In order to simplify training and to increase operationalefficiency, all measurements to be made with one instrument weregrouped together on the data sheet. In this way any one measurerlearned the use of only one type of instrument and was responsiblefor a block of related measurements. The fifty-two measurements,therefore, were divided into four groups or blocks, so that anindividual would be measured by four measurers in turn as heprogressed through the processing line. The instructions used intraining the measurers are given in Appendix B; these instructionsshow the order of the measurements in accordance with the datasheet.

The training of the measurers was carried out by the anthro-pologist in charge of the survey. Four training sessions wereutilized, and three measuring teams or 15 men were trained at eachsession. Initially, the measurers were briefed on the survey andtheir duties were explained. The anthropometric instruments werethen demonstrated and their use described. Sketches illustratingthe measurements and sample data sheets were distributed to themeasurers so that they could become familiar with the measurementsand the sequence in which they were to be taken. The measurersthen practiced with the instruments by measuring each other.After becoming familiar with the use of the instruments, themeasurers were drilled by repeatedly measuring the instructor andseveral test subjects in order to achieve consistency andreliability.

The measurement of personnel during the survey at Bangkok,Don Muang and Sattahip was carried out under the supervision ofthe anthropologist in charge, while the subsequent measuringsessions at Chiengmai, Haad Yai and Ubol were supervised by ColonelPrasert, RTA. Techniques of measurement were frequently checkedfor accuracy and consistency.

d. Data Processing

Processing of the data from the anthropometric survey ofThailand was accomplished by the Computer Branch, U. S. Army NatickLaboratories, Natick, Massachusetts. After coding the backgroundinformation, all of the data were transferred from the data sheetsto punched cards. Three cards were required for the data on eachman in the series.

The background data and the measurement data were checked byexamination of print-outs from the punched cards in order toeliminate duplications and obvious errors. The data for each ofthe 52 measurements were checked by careful examinations of theranges and frequency distributions.

Computations of statistical values for the anthropometric datawere then carried out on a General Electric 225 digital computer.These computations were based upon the use of ungrouped wholecentimeter values for the larger body measurements. In the case ofthe smaller measurements of the head, hands and feet, the data weregrouped into five millimeter (.5 centimeter) intervals.

Most of the statistical values are reported as computed. Inthe case of the percentiles, however, a further check on thecomputed values was made by plotting percentile curves. In thismethod, the cumulative percentages from the frequency distributionof each measurement are plotted on probability scale graph paperand the points are connected by a smooth line or curve. The per-centile values given in this report are those read from thesesmoothed curves. The percentile values shown in inches wereobtained by multiplying the metric values by .3937.

3. DESCRIPTION OF THE SAMPLE

a. Introduction

Although the main purpose of the survey was to obtain dataon the body sizes of Thai military personnel, various other kindsof background information were recorded so that the samples of menwho were measured could be described and characterized. The back-ground data which were recorded for each man included the following:name and serial number, location and date of measuring, birthplaceand home, religion, age, military service, branch, unit, rank,military specialty or duty and length of service.

c. Locations of Measuring

Military personnel were measured at ten locations inThailand during the survey. Five of these locations were Royal ThaiArmy installations in Bangkok. Royal Thai Air Force personnel weremeasured at Don Muang airfield, 29 kilometers north of Bangkok.Royal Thai Marine Corps personnel were measured at the Royal ThaiNaval Station at Sattahip, located on the Gulf of Thailand approxi-mately 170 kilometers southeast of Bangkok. Additional personnelwere subsequently measured at three Royal Thai Army posts locatedat Haad Yai, near Songkhla in the south; at Ubol in the east; andat Chiengmai in the north. (See map, Figure 1).

On the basis of geographical distribution, a large Army sample,or 40 percent of the total series, was measured in Bangkok whilethree smaller Army samples comprising 28 percent of the total serieswere measured in the south, east and north of Thailand. The AirForce and Marine Corps samples, eleven and 21 percent of the totalseries respectively, were measured near Bangkok. A summary of thelocations of measuring and the number of men measured at eachlocation is given in Table 3.2.

d. Background Information

(1) Age

The information on age for the series of men measured inThailand is summarized in Table 3.3 while the distribution of age isgiven in Table 3.4. The statistical terms of mean, standard deviation(S. D.) and co-efficient of variation (V) are discussed in Section 4c.

Mean age for the total series was 24 years, with a standarddeviation of four years. Although the range of age for the totalseries was from 17 to 52 years, 62.7 percent of the series were 21 and22 years old. The sample of Marine Corps personnel had the lowest meanage, 22 years, and the lowest standard deviation, 1.8 years; 59.1 per-cent of the Marines were 21-and 22-year eld men. The Army sample hada mean age of 24.2 years, with 70.7 percent concentrated in the 21-22year age group. The Air Force sample showed the highest mean age of26.8 years. This group included 22 officers with a mean age of 28.7years; these were the only officers measured during the survey. Themean age of the Air Force series of 308 men, excluding officers, was26.7 years.

(2) Geographical Distribution

There are four natural regions based on the pattern ofrivers and mountains in Thailand. These are the Central Plain,formed by the basin of the Chao Phraya River; the East, consisting ofthe Khorat Plateau area; the North, an area of hills and valleys; andthe South, the region of the peninsula. However, for convenience the71 provinces or changwats of Thailand are grouped into nine geographi-cal regions. These regions are those utilized for administrativepurposes, primarily by the Ministry of the Interior. The nine regionsand the provinces included in each region are listed in Table 3.5.The provinces have the same names as their provincial capitals, withthe exception of Pra Nakorn province whose capital is Bangkok. Thenine regions, which are numbered counter-clockwise from Bangkok, havebeen designated by their approximate directions from Bangkok and areshown in the outline map in Figure 1.

Region One (Central) consists of eleven comparatively smallprovinces in the central part of Thailand at the head of the Gulf ofThailand. Bangkok, the capital and largest city of the country, islocated in Pra Nakorn province and dominates this area of low-lyingflood plain and high population density. Region Two (Southeast),containing seven provinces, is in the southeastern part of the countrybordering Cambodia and the Gulf. Regions Three and Four are in theKhorat Plateau area of eastern Thailand. Region Three (East), withsix provinces, forms the southern portion, and Region Four (Northeast),with nine provinces, forms the northern portion of this area. RegionFive (North) consists of seven provinces in the north of Thailandcharacterized by high hills and deep valleys. Region Six (Northwest),with nine provinces, lies in the upper central valley area of thecountry. Region Seven (West), consisting of eight provinces, islocated to the west of the central area, along the border with Burma.Region Eight (Southwest), with seven provinces, lies in the narrowsouthern extension of Thailand in the Isthmus of Kra area. RegionNine (South) comprises seven provinces in the extreme southern part of thecountry, bordering Malaysia.

According to reports based upon the 1957 census, the population ofThailand was 22,800,000. A United Nations estimate of 1961 gives thepopulation as 27,181,000. The population is concentrated mainly in theriver valleys. The entire southern portion of the Central Plain around

Bangkok and Thonburi is the most thickly populated area, followedclosely by the northern portion of the Central Plain around Lopburi andSingburi. Other areas of relatively high population concentration arethe valleys of the Chi and Mun Rivers in the Khorat Plateau region inthe east, and the Chiengmai area of the north, as well as portions ofthe east coast in the south of Thailand, particularly betweenNakornsrithamaraj and Songkhla and between Pattani and Narathivas.Bangkok, the capitol, is the largest city in Thailand with a populationof 1,330,153. Thus, about five percent of the population of Thailandis concentrated in Bangkok.

Average population density in Thailand is about 137 persons persquare mile. However, in areas of high population concentration, suchas in the river valleys, the density is over 200 per square mile.Since only about 18 percent of the total area is cultivated, there ismore significance in the average density per cultivated square mile,which is near 550. The Chao Phraya valley has over 600 persons persquare mile of cultivated land, and some sections of the narrow south-east coastal area have over 3,000.

The population densities for the nine geographical regionsdiscussed above are not available. However, based upon the populationdensities of the 71 provinces, it is estimated that Region One has thehighest population density, while Regions Four and Seven have mediumdensities. Population densities in the other six regions are relativelylower.

The geographical distribution of the series of men measured inThailand may be assessed by examining the information on birthplaceand home which were recorded when the men were measured. Locations ofbirthplace and home were recorded by province rather than by city ortown. The geographical distribution of birthplace is shown in Table3.6.

About 37 percent of the total series of men measured in Thailandwere born in Region One, while about two-thirds (or 65.4 percent) werefrom the central part of the country comprising Regions One, Two andSeven. A smaller group of the total series (30.2 percent) came fromRegions Three, Five and Nine; the majority of these individuals wereArmy men measured at Ubol in the east, at Chiengmai in the north and atHaad Yai in the south. Only 4.4 percent of the total series were bornin Regions Four, Six and Eight.

In the Army sample, 56.1 percent were born in the central part ofthe country (Regions 1, 2, 7), 42.4 percent were from Regions 3, 5 and9 and only 1.5 percent were from the remaining three regions. Most ofthe Marine Corps personnel (87 percent) were born in the central areaof Regions 1, 2 and 7, with the remaining 13 percent from the rest ofThailand. Three fourths (75.5 percent) of the Air Force sample wereborn in Regions I and 7, with 24.5 percent from the rest of the country.

In summary, the geographical distribution of Thai militarypersonnel with respect to birthplace shows that two-thirds of the serieswere from the central area of the country (Regions 1, 2, 7). Thirtypercent were from the east, north and south (Regions 3, 5, 9). Lessthan five percent of the series were from the northeast, northwest andsouthwest (Regions 4, 6, 8). Data are not available upon which to basespecific correlations between regional population densities and samplesof military personnel from the nine geographical regions. However, itmay be noted that the series of military personnel measured in Thailandis deficient in numbers of men from the northeast, the northwest andthe southwest.

In addition to birthplace, the home province was recorded for eachman. Originally, it was intended that this information would refer tothe man's home or residence prior to entry into military service. How-ever, it is believed that most responses indicate the man's presentresidence, thus corresponding to the area of his military assignmentrather than to his home. The geographical distribution of home orresidence is shown in Table 3.7. Of the total series, 68.2 percentrecorded their home province in the central area of Regions 1, 2 and 7.The home province was listed by 29 percent as in the east, north orsouth (Regions 3, 5, 9), while only 2.8 percent listed their homeprovince in Regions 4, 6 or 8.

The correspondence between birthplace and home may be seen in Table3.8. There are two possible interpretations of the information in thistable. One is that there is a close correlation between the birthplacesand homes of military personnel in Thailand. If, however, "home" is anindication of a man's military assignment, it is apparent that men tendto be assigned to the area in which they were born.

(3) Religion

The traditional religion of Thailand is TheravadaBuddhism, which is also known as Hinayana or Southern Buddhism. Over90 percent of Thais are Buddhists. The largest religious minority inThailand consists of Moslems who are concentrated in the southadjacent to Malayasia. Some additional Moslems are scattered in smallgroups in central and northern Thailand.

The distribution of religion for the series of military personnelmeasured in Thailand is shown in Table 3.9. In the total series,about 94 percent were Buddhists and six percent were Moslems. Two-thirds of the men listed as Moslem were born in the southern provincesof Region 9.

(4) Military Service, Branch and Unit

The series of military personnel measured during theanthropometric survey of Thailand included representatives of the RoyalThai Army, Marine Corps and Air Force. The Army sample of 2,010 mencomprised 68 percent of the total series. The Marine Corps sample of610 men represented about 21 percent of the series, while the Air Forcesample of 330 men represented about 11 percent of the total series.Although no Navy personnel as such were measured during the survey, thesample of Marine Corps personnel may be considered to represent the Navysince the Marine Corps is an integral part of the Royal Thai Navy. Itwas requested that military personnel of all ages and ranks be measuredduring the survey. No selection of personnel was made in that all menmade available by their commanding officers were measured.

With respect to branch of service, approximately half of the Armysample (or 1,016 men) consisted of infantrymen of the First InfantryDivision measured in the Bangkok area. A small sample of 171 men of theArmy's Transportation Corps also was measured in Bangkok. Army personnelof the three Regimental Combat Teams measured at Haad Yai, Ubol andChiengmai were predominantly infantrymen, although some artillery andservice personnel also were included. The Marine Corps sample includedinfantry personnel, a few artillerymen and a group of petty officercadets in training. The Air Force personnel, drawn from the First and

(5) Rank

Most of the military personnel measured during theanthropometric survey of Thailand were enlisted men, comprising 94.9percent of the total series. Non-commissioned officers made up 4.3percent of the total series. The only officers measured were Air Forcepersonnel; these 22 pilots and navigators comprised 0.8 percent of thetotal series.

Distribution of rank is shown separately for the Army, MarineCorps and Air Force in Tables 3.12, 3.13 and 3.14 respectively. Inthese tables the Thai rank is given, followed by an approximateEnglish translation of the term. For comparison the approximatelyequivalent United States Army, Marine Corps or Air Force ranks also areincluded.

The largest group of Army men measured were recruits; 75.3 percentof the Army sample were of this rank. Another 23.2 percent of the Armysample were enlisted men. While the translations of the three ranks inthis group are given as senior, intermediate and junior private theycould also be called sergeant, corporal and private first class sincethese men wear three, two or one stripes, respectively. Only 1.5percent of the Army sample were non-commissioned officers or "firstthree graders" in U. S. Army terms.

(6) Military Duty or Specialty

The military duties of Thai personnel measured during thesurvey covered a wide range of assignments or specialties. Althoughsome difficulties were encountered intranslating the duty designationsfrom Thai into English, it was possible to group personnel into generaloccupational categories. These groupings are summarized in Table 3.15.

Personnel of the Royal Thai Army may be classified as infantry ornon-infantry on the basis of their military assignments. Threecategories are shown under infantry: headquarters, rifle platoon andweapons platoon personnel. Headquarters personnel are those assignedto administration, communications, messing, supply and transportationduties. Rifle platoon personnel are primarily men designated asriflemen, automatic riflemen, or machine gunner, while weapons platoonpersonnel are trained in the use of recoilless rifles or mortars. Thelargest group of non-infantry personnel are designated as recruits ortrainees, while smaller samples of artillery, transportation, medicaland miscellaneous personnel also are included. The sample of Royal ThaiArmy personnel also may be classified on the basis of combat or supportassignments. On this basis, about 53 percent are combat personnel, andabout five percent are support personnel, while 42 percent are recruitsor trainees.

The Royal Thai Air Force sample measured in the survey includedflying, ground and support personnel. Flying personnel included theduties of pilot, navigator, flight engineer, radio operator and crewchief. A total of 29 pilots was measured; fifteen were officers andfourteen were non-colmissioned officers. Five navigators also wereofficers, while the other flying personnel were NCOs or Airmen IstClass. Air Force ground personnel included mechanics, armorers andradio and radar technicians. The support category consisted ofindividuals assigned to administrative duties such as supply, finance,transportation or guards.

(7) Length of Military Service

The length of military service among Thai personnelmeasured during the survey ranged from a few months for 21-year-oldrecruits to as much as 31 years in the case of a 52-year-old Armysergeant. The distribution of length of service is given in Table3.16 and is summarized in Table 3.17. In the total series 38 per-cent had been in service from one to eleven months while 31 percenthad been in service from twelve to 23 months. Thus, 69 percent ofthe total series had less than two years of military service, and31 percent had between two and 31 years of service.

b. Percentile Values

Presentation of anthropometric data in the form of percentilevalues is one of the most useful and practical methods for purposes ofclothing and equipment sizing, design guidance and other humanengineering applications. The data from this anthropometric survey aregiven in four tables (Tables 4.1 - 4.4) which show nine percentilevalues for each measurement. These data are based upon the total seriesof 2,950 men. The values are given in centimeters, with the exceptionof weight (No. 52) which is shown in kilograms. Facing each of thetables are sketches which indicate the location of each body measurement(Figures 2-5).

In using the percentile values, it may be pointed out that fora particular dimension, the measurement on 95 percent of the men inthe series will be equal to or less than the value shown for the95th percentile, while on the remaining five percent, the measurementwill be greater than the 95th percentile value. In the case ofstature, for example (Table 4.1), 95 percent of Thai militarypersonnel will be 172 centimeters or less in height, while only fivepercent will be taller than 172 centimeters. Similarly, the measure-ment on five percent of the men in the series will be equal to orless than the value shown for the 5th percentile, while on theremaining 95 percent, the measurement will be greater than the 5thpercentile value. Again, in the case of stature, five percent ofThai military personnel will be 155 centimeters or less in height,while 95 percent will be taller than 155 centimeters. In effect,then, the 1st and 99th percentile values of a measurement indicatethe range of that measurement for the middle 98 percent of thepopulation, while the 5th and 95th percentile values of a measure-ment define the range for the middle 90 percent of the population.

For ready reference by those not accustomed to the metricsystem, percentile values for all of the body measurements aregiven in inches in Tables 4.5, 4.6 and 4.7. Weight (52 in Table4.7) is shown in pounds.

c. Means and Standard Deviations

While the anthropometric data for a population are useful inthe form of percentiles, othe'r statistical values also are of interest.There are two kinds of averages frequently employed for anthropometricdata. These are the arithmetic mean and the median. The mean of ameasurement is the average value of that measurement, obtained bydividing the sum of the values by the number of values. The medianmay be defined as the middle value in a series of data. Since themedian corresponds to the 50th percentile value, medians are not shownseparately here, but they may be found in the tables of percentiles.

The standard deviation (S.D.) is an indication of the variabilityof a measurement within the population. If most of the values for ameasurement are close to the mean value, the standard deviation willbe small, but if many of the values are much lower or higher than themean, the standard deviation will be large. As a general estimate,the mean minus one standard deviation and plus one standard deviationwill give a range which covers approximately the middle two-thirds ofthe values for any given measurement. Similarly a range determined bysubtracting and adding two standard deviations from and to the meanwill include approximately 95 percent of the values for a givenmeasurement. Practically all of the values of a measurement will fallwithin a range determined by subtracting and adding three standarddeviations from and to the mean value of that measurement.

Finally, the coefficient of variation (V) is a statistical valuewhich expresses the standard deviation as a percentage of the mean.

Although the anthropometric survey of Thailand included samplesof men drawn from the Royal Thai Army, the Royal Thai Marine Corpsand the Royal Thai Air Force, the percentile values for the bodymeasurements discussed above are based upon the total series of 2,950Thai military personnel. However, additional statistical values havebeen computed for the total series, and for the Army, Marine Corps andAir Force samples separately. These statistical values, consisting ofthe mean, the standard deviation (S.D.) and the coefficient of variation(V) for each body measurement are presented in Tables 4.8, 4.9 and 4.10.The means and standard deviations are given in centimeters (with weightin kilograms), while the coefficients of variation are expressed aspercentages.

5. DISCUSSION OF THE DATA

a. Royal Thai Armed Forces

Since the survey included samples from the Army, Marine Corps andAir Force, data for these groups have been analyzed separately. Asummary of the statistical values for the Royal Thai Armed Forces isgiven in Table 5.1.

The samples from the three services differ somewhat in mean age.The Marine Corps sample has the lowest mean age, the large Army sampleis intermediate in age, while the Air Force sample shows the highestmean age. Average weights for the three services reflect the differ-ences in mean age. The Marines are lightest, the Army sample is inter-mediate, while the Air Force group has the highest mean weight. Withrespect to stature, Army personnel show the lowest average (162.9 cm);the Marines are one centimeter taller (163.9 cm), while the Air Forcesample (165.4 cm) averages 1.5 centimeters taller than the Marines.Army and Marine Corps personnel have the same average chest girth(84.9 cm), but the Air Force sample is somewhat larger in this measure-ment (86.1 cm). While it may be demonstrated that these differencesare significant on the basis of statistical analysis, the differencesin body size among the Armed Forces are not considered to be ofpractical significance.

Number of Men 2,010 610 330

b. Geographical Differences

Ot the large Royal Thai Army sample (2,010 men) in the survey,1,187 men (59 percent) were measured in the Bangkok area, while 823 men(41 percent) were measured at three RTA installations at Haad Yai, Uboland Chiengmai. The analysis of birthplace has shown that in general menare stationed in the area in which they were born. The Army personnelmeasured in Bangkok, therefore, are predominantly men from the centralpart of Thailand, while those measured at Haad Yai, Ubol and Chiengmaiare laregly from the south, east and north, respectively.

The statistical values for body size of Army men measured inBangkok, as" contrasted with Army men measured at the other threelocations, are given in Table 5.2. The Bangkok Army personnel are,on the average, heavier by .6 kilograms and taller by 2.8 centimeters,but they are also smaller in chest girth by 1.2 centimeters. TheArmy personnel measured in Bangkok are, however, about three and onehalf years older in mean age, which may be explained by the fact thata large number of the troops measured at the other three Armyinstallations were 21 and 22-year-old recruits.

c. Age Changes in Weight and Stature

When the data of an anthropometric survey are sufficient towarrant such analysis, it is of interest to examine the changes inweight and height in a population with increasing age. Means andstandard deviations for the weight and stature of Thai militarypersonnel have been calculated for age groups between 18 and 35 years,as shown in Table 5.3. The data indicate a gradual increase in bothweight and height with increasing age. Mean weight in this seriesbegins with a value of 52 kilograms at age 18, and rises sharply to 56kilograms in the 20-22 year age group. Mean weight for 27-year-oldsis about 58 kilograms, while the highest weight in this series is about60 kilograms at age 34. The lowest mean stature in this series is 162.4centimeters at age 21. Stature increases to 166.0 centimeters for27-year-olds, with a maximum of 166.6 at age 32.

d. Nutrition Survey of Thailand

In any anthropometric survey, questions relating to therepresentation of the samples of men measured or to the reliability ofthe data may be raised. In the case of Thailand, it is fortunate thatcomparable data on height and weight are available. These datacorroborate the results of the anthropometric survey.

Between October and December 1960, a nutrition survey was conductedin Thailand by a joint Thai-American team under the sponsorship of theInterdepartmental Committee on Nutrition for National Defense of theUnited States Department of Defense. The report on this survey waspublished in February, 1962. During the survey, clinical and nutritionalstudies were made on 4,325 Royal Thai Army, Navy (Marine Corps), and AirForce personnel at eleven military installations in Thailand. Severalof the units sampled in the nutritional survey of 1960 were the same asthose sampled in the anthropometric survey of 1962. The Royal Thai Armyunits were the l1th Infantry Regiment (Bangkok), the 5th RegimentalCombat Team (Songhkla), the 6th RCT (Ubol), the 7th RCT (Chiengmai),while Royal Thai Marine Corps personnel at Sattahip also were sampled inboth surveys.

A summary of the pertinent data from the anthropometric andnutrition surveys of Thailand is given in Table 5.4. In the totalseries (combined services), Thai personnel measured in the anthro-pometric survey averaged two years older, .9 kilograms heavier and.4 centimeters -taller than men measured during the nutrition survey.In general, the means of age, weight and height for the differentservices are comparable in the two surveys. While the data obtainedin the two surveys show some minor differences, these are not con-sidered to be of practical significance.

e. Related Anthropometry of Other Countries

Since data on the height and weight of Thai military personnelare now available from both anthropometric and nutrition surveys, it isof some interest to compare these values with similar data for samplesof military personnel of other Asian countries. Means of weight andstature for various Asian countries are given in Table 5.5, togetherwith the mean ages of the samples measured. An anthropometric survey ofmilitary personnel of the Republic of Vietnam was conducted in 1963,(under the sponsorship of ARPA) while a nutrition survey was carried outthere in 1959. Nutrition surveys also were conducted between 1956 and1961 in Pakistan, Burma, The Philippines, the Republic of China (Taiwan)and the Republic of Korea, all under the sponsorship of the United StatesInterdepartmental Committee on Nutrition for National Defense. The datashown in Table 5.5 have been abstracted from the reports of thesenutrition surveys.

The data in Table 5.5 indicate that Thai military personnel areapproximately four kilograms heavier and three centimeters taller onthe average than Vietnamese military personnel, although the Thaiseries have lower mean ages. Thai military personnel also areslightly heavier (three kilograms) but of about the same height on theaverage as Burmese military personnel. While the military sample fromthe Philippines is older, with an average age cf 30 years, theFilipinos show about the same weight and height as the Thais. TheThais appear to be slightly shorter than Chinese and Korean militarypersonnel; they are also of about the same mean weight as the TaiwanChinese, but a few kilograms lighter in weight than Koreans. Thaimilitary personnel are approximately 2.5 kilograms lighter thanPakistani military personnel, and almost seven centimeters shorter instature.

An approximation of body build may be made through the use of anindex expressed by dividing stature by the cubic root of weight. Onthis basis, the data on height and weight shown in Table 5.5 indicatethat, in general, Pakistanis, Burmese, Chinese and Vietnamese appearto be relatively slender for their height, while Filipinos, Thais andKoreans are relatively heavier for their height.

6. HUMAN FACTORS IMPLICATIONS OF THE DATA

a. Human Engineering

The anthropometric data presented in this report shouldreceive wide use and application in the human engineering ofequipment for Thai military personnel. The utilization ofinformation on the body size of Thai military personnel will serveas an important factor in improving the efficiency and performanceof Thai man-equipment systems.

Detailed sizing and space requirements for military equipmentintended for use by the Royal Thai Armed Forces may be developedfrom the body size data of this report. The specific informationrequired will vary with the design problem under consideration,but most of the basic requirements with respect to body size areincluded within the 52 body dimensions taken during this survey.

Many human engineering problems in design, sizing andadjustability involve the spatial requirements of the seatedoperator. Data on sitting height, eye height, shoulder height andknee height, as well as shoulder and hip breadths are required forthe seated operator. Also of importance in this category are thearm reach measurements.

In considering the use of American equipment by the RoyalThai Armed Forces, some of the differences in body size betweenThai and U. S. military personnel may be noted. The average weightof Thai military personnel is 56 kilograms (124 pounds), while U. S.Army men average 70.4 kilograms (155 pounds). The difference ofabout 30 pounds in average body weight is of considerable importancewith respect to the weight to be carried by the individual soldier.If it is assumed that the soldier's load should not exceed one-thirdof his body weight, it is apparent that the American soldier couldcarry about 23 kilograms or 50 pounds. on the average, whereas theThai soldier should be limited to about 18 kilograms or 40 pounds.

The average height of Thai military personnel is 163o4centimeters (64.3 inches); this value is equivalent to the 5thpercentile of U. S. Army stature, In other words, only five percentof U. S. Army men are shorter than the average Thai, while 95 per-cent are taller. The average height of U. S. Army men is 174.0centimeters (68.5 inches);'thus, the American soldier is about 10.6centimeters (4.2 inches) taller on the average than the Thaiserviceman.

51

Page 57: ANTHROPOMETRIC SURVEY OF THE ROYAL THAI ARMED FORCES · of July 27, 1962, Subject: Anthropometry Research in Southeast Asia. Body measurements were obtained on a total series of 2,950

The difference in stature between American and Thai militarypersonnel is also reflected in the differences in other bodyproportions. The Thai soldier has a shorter torso and shorter armsand legs than the American. These differences become important inhuman engineering considerations, since it is obvious that inoperating American equipment, the Thai cannot reach as far with hishands or his feet as the American.

Body girth and body breadth measurements are smaller for Thaimilitary personnel. Items of personal equipment intended for useby Thais, such as load-carrying suspenders and belts or parachuteharnesses must be capable of adjustment to acconmmodate these smallergirths.

b. Clothing

Since no information is available as yet on the size systemsfor military clothing currently in use by the Armed Forces ofThailand, no attempt is made here to assess the adequacy of such sizesystems with respect to the anthropometric data now available. How-ever, some general comments may be made on the ranges of availableThai body measurements in terms of clothing sizes.

The overall range of stature among Thai military personnel issome 33 centimeters. If clothing is sized in three lengths, eachlength would be required to fit men with a range of 11 centimetersin height. With four lengths of clothing, the range of stature foreach length would be reduced to about 8.25 centimeters. Twoadditional body measurements are of use in considering the lengthsof upper body clothing. One of these is coat length,. which is thevertical distance from the base of the neck to the base of thethumb. Since the overall range of this measurement among Thaimilitary personnel is 26 centimeters, each of three lengths wouldbe required to fit a range of about 8.7 centimeters in coat length.

A second body length measurement is back-waist length, measuredfrom the base of the neck to the waist level, The range of thismeasurement is 17.5 centimeters; thus, each of three lengths wouldbe required to fit a range of about 5.8 centimeters in back-waistlength.

The overall range of chest circumference among Thai militarypersonnel is 27 centimeters. Thus, with three girth sizes of upperbody clothing, each size would be required to fit a range of ninecentimeters. Neck circumference and sleeve lengths are utilizedin the sizing of shirts. The range of neck circumference in thisseries is 10.4 centimeters, while the range of sleeve length is 23centimeters.

52

Page 58: ANTHROPOMETRIC SURVEY OF THE ROYAL THAI ARMED FORCES · of July 27, 1962, Subject: Anthropometry Research in Southeast Asia. Body measurements were obtained on a total series of 2,950

Waist circumference and crotch height (or inseam) are the twobody measurements controlling the sizing of trousers. The overallrange of waist circumference among Thai military personnel is 34centimeters. With three waist sizes of trousers, each size wouldbe required to fit a range of 11.3 centimeters in waist girth. Withfour sizes, the waist girth range for eash size would be reduced to8.5 centimeters. The range of the crotch height or inseam measure-ment is 24 centimeters. Therefore, each of three trouser inseamlengths would be required to fit a range of eight centimeters ininseam.

The range of head circumference may be used for the sizing ofheadwear. Head circumference among Thai military personnel coversa range of 6.5 centimeters.

The overall range of foot length among Thai military personnelis about seven centimeters, while the range of foot breadth is 3.25centimeters. In general, the Thai foot appears to be relativelyshort and broad. The hands of the Thai soldier also are relativelyshort and broad.

In conclusion, it is obvious that only a few of the humanfactors implications of the anthropomietric survey of Thailand havebeen suggested. The application of the information on body sizesof Thai military personnel will involve a research effort coveringseveral years. A start has been made, however, and data on therange and variation in body size in the military population ofThailand are now available for use.

7. SUMMARY

During an anthropometric survey of military personnel ofThailand, 52 body measurements were made on 2,950 members of theRoyal Thai Armed Forces. The series included samples of men fromthe Army, Marine Corps and Air Force. The resulting anthropometricdata have been analyzed and are available for application in sizesystems for clothing and personal equipment and in the humanengineering of man-operated equipment for the military populationof Thailand.
