    BACKGROUND: Knee laxity measurements have been shown to be associated with some medical conditions such as chronic joint pain and collagen tissue diseases. The aim of this study was to determine the effects of demographic factors and anthropometric measures on knee laxity.
    MATERIALS AND METHODS: Data were collected from 521 visitors, staffs and students from the University Malaya Medical Centre and University of Malaya between December 2009 and May 2010. Knee laxity was measured using a KT-1000 arthrometer. Multiple regression analysis was used to find the association of knee laxity with age and anthropometric measures.
    RESULTS: Using ANOVA, knee laxity did not show significant differences among ethnic groups for both genders. The average knee laxity in men was 3.47 mm (right) and 3.49 mm (left); while in women were 3.90 mm (right) and 3.67 mm (left). Knee laxity in women was significantly higher (right knee p<0.01 and left knee p<0.05) than men. Right knee laxity of men was negatively associated with height (p<0.05) and BMI (p<0.05); also a negative association was observed between left knee laxity and BMI (p<0.05). Overweight and obese men had less knee laxity than normal weight and underweight individuals. Elderly men and women (age 55 and above) had lower knee laxity (p<0.01) than young adults (ages 21-39).
    CONCLUSION: These results suggest that age and body size are important factors in predicting knee laxity.

    INTRODUCTION: Post-mortem computed tomography (PMCT) provides information that helps in the determination of the cause of death and corpse identification of disaster victims. One of the methods for corpse identification includes assessment of the body stature. There is a lack of post-mortem imaging studies that focus on the anthropometric assessment of corpses. Our aim was to identify the relationship between cadaveric spine length and autopsy length (AL) among and autopsy length (AL) among a Malaysian population and derive a regression formula for the estimation of corpse body height using PMCT.

    MATERIALS AND METHODS: We retrospectively assessed 107 cadavers that had undergone conventional autopsy and PMCT. We made 5 measurements from the PMCT that included cervical length (CL), thoracic length (TL), lumbosacral length (LS), total column length of the spine, excluding the sacrum and coccyx (TCL), and ellipse line measurement of the whole spine, excluding the sacrum and coccyx (EL). We compared these anthropometric PMCT measurements with AL and correlated them using linear regression analysis.

    RESULTS: The results showed a significant linear relationship existed between TL and LS with AL, which was higher in comparison with the other parameters than the rest of the spine parameters. The linear regression formula derived was: 48.163 + 2.458 (TL) + 2.246 (LS).

    CONCLUSIONS: The linear regression formula derived from PMCT spine length parameters particularly thoracic and lumbar spine gave a finer correlation with autopsy body length and can be used for accurate estimation of cadaveric height. To the best of our knowledge, this is the first ever linear regression formula for cadaveric height assessment using only post mortem CT spine length measurements.

    This paper describes the findings of a survey on perinatal cases in Kuala Lumpur. Information on the deceased infants and their deliveries were documented as well as selected social, demographic and anthropometric data on the mothers. This includes quality of the home environment in terms of presence of basic amenities. It was evident that the lower classes were better represented in the sample.
    This paper also highlights a major problem in retrospective studies, that of successfully tracing eligible respondents. There were also cases of non-cooperation. Another problem which emerged, and one common to many developing countries, was the incompleteness of birth weight records.

    A cross-sectional study of the nutritional status of schoolchildren aged 7-10 years from the Kuala Betis Resettlement Scheme in Gua Musang, Kelantan was done. A total of 291 schoolchildren were examined but only 183 (62.9%) fecal samples were returned for geo-helminth infection analysis. The prevalence of stunting was 40.4% and underweight was 28.4%. A total of 127 schoolchildren (69.4%) were positive for at least one of the 3 geo-helminth infections. The most common geo-helminth was Ascaris lumbricoides (62.8%), followed by Trichuris trichiura (38.9%), and hookworm infection was relatively low (12.6%). All the anthropometric indices measured were lower in the geo-helminth infected children compared to the uninfected childen, except for the weight-for-height z-score. However the differences were insignificant Geo-helminth infections may not be a significant factor in malnutrition of these schoolchildren. However, with the availability of safe, efficacious and cheap broad spectrum anthelmintics, regular mass treatment should be given in selected areas where the prevalence of geo-helminth infections is still high, so that these schoolchildren will be able to achieve their growth potential during their school years.

    This study aimed to determine the relationship between blood lead (BPb) concentrations and cognitive and physical development in school children. A total of 169 urban children and 100 industrial children of Malay ethnicity, in the age range of 6(1/2) to 8(1/2) years, were selected. BPb was determined using GF atomic absorption spectrophotometer. The mean cognitive score (102.55) of the children from the industrial area was significantly higher than that of the urban children (95.09; P < .001). However, no significant differences were found in the BPb levels between the 2 groups (industrial, 3.75 microg/dL; urban, 3.56 microg/dL). There was significant inverse correlation between BPb and cognitive scores for all children (P < .05). The cognitive scores for all children were influenced by BPb after adjustments (P < .05). The urban children had significantly better Weight for Height and Left Arm Circumference values than those from industrial area. There was no significant correlation between BPb and the anthropometric measurements. In conclusion, low BPb influenced the cognitive development, whereas physical development was not affected.

    AIM: Both inadequate and excessive weight gain during pregnancy can have immediate and long-term health risks for women and infants. This study investigated rate of gestational weight gain (GWG) and its associated factors in Malaysian pregnant women.
    METHODS: This cross-sectional study was conducted at maternal and child health clinics in Selangor and Negeri Sembilan between November 2010 and April 2012. A pre-tested questionnaire was used to obtain sociodemographic, obstetric, dietary intake and physical activity information. Current weight and height were measured using standard procedures. GWG rate was calculated as the average weekly weight gain in that particular trimester of pregnancy and further categorized according to the Institute of Medicine (IOM) recommendations.
    RESULTS: Mean GWG rate for all pre-pregnancy BMI categories in the second and third trimesters was higher than the IOM recommendations. Overweight women (adjusted OR, 4.26; 95%CI: 1.92-9.44) and women <153 cm tall (adjusted OR, 1.96; 95%CI: 1.21-3.18) tend to have inadequate GWG rate. Women with high pre-pregnancy body mass index (BMI; ≥25.0 kg/m(2) ; overweight: adjusted OR, 3.88; 95%CI: 2.12-7.09; obese: adjusted OR, 2.34; 95%CI: 1.28-4.29) and low physical activity (adjusted OR, 1.74; 95%CI: 0.77-3.97) were two-threefold more likely to have excessive GWG.
    CONCLUSION: Both inadequate and excessive GWG can have detrimental effects on the health of mothers and infants. Pre-pregnancy BMI, height and physical activity should be emphasized in prenatal care to ensure that women have adequate GWG rate.

    BACKGROUND AND OBJECTIVES: Information on the growth status of indigenous children is useful for developing intervention strategies, but the data are limited. This study determined the prevalence of undernutrition among under-five indigenous children (Orang Asli) and tracked the growth status of Orang Asli children aged 0-3 years.

    METHODS AND STUDY DESIGN: This study had two phases: a cross-sectional growth study of under-five Orang Asli children (N=304; Phase 1) and a 2-year prospective cohort growth study of Orang Asli children aged 0-3 years (N=214; Phase 2) in the Temerloh district of Pahang, Malaysia. Weight-for-age, length/height-for-age, weight-for-length/height, and body mass index-for-age were determined.

    RESULTS: The prevalence rates of stunting, underweight, wasting, and thinness in under-five Orang Asli children (Phase 1) were 64%, 49%, 14%, and 12%, respectively. In the cohort of 214 children (Phase 2), weight-for-age was initially documented and maintained closely at -1.50 standard deviations (SD) in the first 6 months, but it declined to approximately -2.00 SD at 15 months and remained close to -2.00 SD thereafter. Length/height-for-age declined rapidly to approximately -2.50 SD at 18 months and fluctuated between -2.30 and -2.50 SD thereafter. Weight-for-length/height increased sharply to -0.40 SD at 2-3 months, declined gradually to less than -1.00 SD at 12 months, and plateaued between -1.00 and -1.30 SD thereafter.

    CONCLUSIONS: Undernutrition is prevalent among Orang Asli children, with length rather than weight faltering being more pronounced in the first 2 years of life. Identifying the causes of early growth retardation in this population is required to inform future preventive strategies.

    When standing height (StndHt) cannot be assessed, arm span (AS) or sitting height (SitHt) has been used as surrogate variables for prediction of StndHt in adult caucasians and blacks. We examined (1) the relationship between StndHt, AS and SitHt among adult Chinese, Malays and Indians; and (2) whether anthropometry could explain the ethnic differences in lung volumes (as StndHt-adjusted lung volumes are known to differ significantly: Chinese > Malays > Indians). We recruited 1250 consecutive outpatients aged 20-90 years. Prediction equations of StndHt (with AS, SitHt, weight, age as predictors) for each subgroup of race and sex were formulated with multiple linear regressions. Equations with both AS and SitHt as predictors had the best goodness of fit (SEE = 2.37-2.85 cm, adjusted R2 = 0.67-0.87), as compared to equations with either AS (SEE = 3.00-3.91 cm, adjusted R2 = 0.58-0.80) or SitHt alone (SEE = 3.48-4.00 cm, adjusted R2 = 0.45-0.76). GLM general factorial analyses found that age- and weight-adjusted SitHt-to-StndHt ratios differed significantly among Chinese (0.539), Malays (0.529) and Indians (0.518). This paralleled the ethnic differences in lung volumes. The equations with both AS and SitHt as predictors provide the most accurate estimate of StndHt. Ethnic differences in upper body segment length may explain in part the lung volume differences.

    This study aimed to identify the prevalence of energy misreporting amongst a sample of Malay children aged 9-11 years (n = 14) using a range of commonly used cut points. Participants were interviewed using repeated 24 h dietary recalls over three occasions. The Goldberg equations (1991 and 2000), Torun cut points and the Black and Cole method were applied to the data. Up to 11 of 14 children were classified as misreporters, with more under-reporters (between seven and eight children) than over-reporters (four or less children). There were significant differences in the proportion of children classified as energy misreporters when applying basal metabolic rate calculated using FAO/UNU/WHO (1985) and Malaysian-specific equations (p < 0.05). The results show that energy misreporting is common amongst Malay children, varying according to cut point chosen. Objective evaluation of total energy expenditure would help identify which cut point is appropriate for use in Malay paediatric populations.

    Several distributions of country-specific blood pressure (BP) percentiles by sex, age, and height for children and adolescents have been established worldwide. However, there are no globally unified BP references for defining elevated BP in children and adolescents, which limits international comparisons of the prevalence of pediatric elevated BP. We aimed to establish international BP references for children and adolescents by using 7 nationally representative data sets (China, India, Iran, Korea, Poland, Tunisia, and the United States).

    CONTEXT: No universal waist circumference (WC) percentile cutoffs used have been proposed for screening central obesity in children and adolescents.

    OBJECTIVE: To develop international WC percentile cutoffs for children and adolescents with normal weight based on data from 8 countries in different global regions and to examine the relation with cardiovascular risk.

    DESIGN AND SETTING: We used pooled data on WC in 113,453 children and adolescents (males 50.2%) aged 4 to 20 years from 8 countries in different regions (Bulgaria, China, Iran, Korea, Malaysia, Poland, Seychelles, and Switzerland). We calculated WC percentile cutoffs in samples including or excluding children with obesity, overweight, or underweight. WC percentiles were generated using the general additive model for location, scale, and shape (GAMLSS). We also estimated the predictive power of the WC 90th percentile cutoffs to predict cardiovascular risk using receiver operator characteristics curve analysis based on data from 3 countries that had available data (China, Iran, and Korea). We also examined which WC percentiles linked with WC cutoffs for central obesity in adults (at age of 18 years).

    MAIN OUTCOME MEASURE: WC measured based on recommendation by the World Health Organization.

    RESULTS: We validated the performance of the age- and sex-specific 90th percentile WC cutoffs calculated in children and adolescents (6-18 years of age) with normal weight (excluding youth with obesity, overweight, or underweight) by linking the percentile with cardiovascular risk (area under the curve [AUC]: 0.69 for boys; 0.63 for girls). In addition, WC percentile among normal weight children linked relatively well with established WC cutoffs for central obesity in adults (eg, AUC in US adolescents: 0.71 for boys; 0.68 for girls).

    CONCLUSION: The international WC cutoffs developed in this study could be useful to screen central obesity in children and adolescents aged 6 to 18 years and allow direct comparison of WC distributions between populations and over time.

    European standards on height, weight, centres of ossification and date of onset of puberty are not applicable to Asiatic girls in Malaya. " Asiatics " could not be grouped together, racial groups showed differences, especially the three main groups-Chinese, Indians and Malays. Nine tables are furnished showing the average and maximum and minimum heights and weights of the four main groups examined, as well as of some of the minor groups, arranged according to ages from 5 years to 19 years. The conclusion is drawn that the European standard of height and weight is higher than that of any of the Asiatic races in Malaya; a greater difference is noted in the weight than in the height and there is a much greater range in the weight of Asiatics but a smaller range in the height. Onset of menstruation tended to be earlier in the local Asiatic groups than in Europeans. The date of eruption of permanent teeth appeared to be earlier among Asiatic races. No deciduous teeth were found at the age of 12-13 years, the lower second molar was seen in all those examined at that age and the whole lower set was present, excluding the third molar. Earlier efuption of the canine teeth was also noticeable. Details should be consulted in the original by all those interested in medico legal work in tropical countries. P. A. Clearkin.

    Lower Perak, an alluvial plain, much of it below spring tide levels, lies between tidal reaches of the large Perak and Bernam rivers. It has a mixed rural population, about 40 per cent. being Malaysians. Inspection, with individual card records, was made of 2, 388 boys in vernacular schools aged 6 to 16 years, local prejudice exempting girls. The diet, largely rice, of these children appears deficient in animal protein, and probably in calcium, iron, phosphorus, and vitamin B. They show few signs of deficiency diseases, have a dental caries rate of about 70 per cent., and one-third had poor muscular development. They suffer mainly from fever, anaemia and skin infections. * An asterisk denotes that the paper dealt with is thought to be of more than ordinary interest to tropical readers. As ages were quite unreliable, only the 513 presenting birth certificates were grouped to the nearest birthday. [img 1T161260A.tif] Comparisons are made with the Baldwin-Wood scale for American medium type boys, who at every age are of superior weight. Full correlation tables are given for the 513 and 2, 388 boys. To eliminate doubtful ages the, Baldwin-Wood tables were used to calculate the mean weights of Americans at the height of the Perak boys, and now the Americans only [img 1T161260B.tif] come out slightly higher than these. The essential difference therefore seems to be more a matter of size and physical development in relation to age, than any significant change in-ratios at different ages. Comparison was made with Kedah measurements. This is a similar district 120 miles north of Lower Perak. Curves are used which are not strictly comparable, as some girls were included, but Dr. J. H. STRACHAN took out the figures of 1, 018 Kedah boys. These are compared with the 2, 388 Perak boys, in weight for inches in height. Although the conditions and districts seem in all respects similar the Kedah boys are significantly lighter for all heights. No explanation has been found for this. The authors insist on the usefulness of correlation tables. " It is obvious that the medium American boys are much heavier than the Malaysian children. But the second American weight/height curve seems to show that if one selects for comparison boys of the same stature at each age, the American boys would be on the whole only slightly heavier than the Lower Perak boys." This investigation has got the utmost value from rather unpromising materials. Any school worker will gain some new viewpoints from its careful perusal. James Kerr.

    Combined heredity of surnames and physique, coupled with past marriage patterns and trade-specific physical aptitude and selection factors, may have led to differential assortment of bodily characteristics among present-day men with specific trade-reflecting surnames (Tailor vs. Smith). Two studies reported here were partially consistent with this genetic-social hypothesis, first proposed by Bäumler (1980). Study 1 (N = 224) indicated significantly higher self-rated physical aptitude for prototypically strength-related activities (professions, sports, hobbies) in a random sample of Smiths. The counterpart effect (higher aptitude for dexterity-related activities among Tailors) was directionally correct, but not significant, and Tailor-Smith differences in basic physique variables were nil. Study 2 examined two large total-population-of-interest datasets (Austria/Germany combined, and UK: N = 7001 and 20,532) of men's national high-score lists for track-and-field events requiring different physiques. In both datasets, proportions of Smiths significantly increased from light-stature over medium-stature to heavy-stature sports categories. The predicted counterpart effect (decreasing prevalences of Tailors along these categories) was not supported. Related prior findings, the viability of possible alternative interpretations of the evidence (differential positive selection for trades and occupations, differential endogamy and assortative mating patterns, implicit egotism effects), and directions for further inquiry are discussed in conclusion.

    The convergent evolution of the human pygmy phenotype in tropical rainforests is widely assumed to reflect adaptation in response to the distinct ecological challenges of this habitat (e.g. high levels of heat and humidity, high pathogen load, low food availability, and dense forest structure), yet few precise adaptive benefits of this phenotype have been proposed. Here, we describe and test a biomechanical model of how the rainforest environment can alter gait kinematics such that short stature is advantageous in dense habitats. We hypothesized that environmental constraints on step length in rainforests alter walking mechanics such that taller individuals are expected to walk more slowly due to their inability to achieve preferred step lengths in the rainforest. We tested predictions from this model with experimental field data from two short-statured populations that regularly forage in the rainforest: the Batek of Peninsular Malaysia and the Tsimane of the Bolivian Amazon. In accordance with model expectations, we found stature-dependent constraints on step length in the rainforest and concomitant reductions in walking speed that are expected to compromise foraging efficiency. These results provide the first evidence that the human pygmy phenotype is beneficial in terms of locomotor performance and highlight the value of applying laboratory-derived biomechanical models to field settings for testing evolutionary hypotheses.
