“…However the conversion of TBW to FFM may have not been affected, as it had been shown that there was no biologically relevant difference in the hydration of FFM across different ethnic groups 28 . Shaikh et al 29 . showed that Fjeld's BIA and Mellits and Cheeks anthropometric equations predicting TBW had a close concordance with TBW assessed by D 2 O in a group of Indian children.…”

Sri Lankan Australian children appear to have a high percentage of fat with a low BMI and some of the available indirect techniques are not helpful in the assessment of body composition. Therefore ethnic and/or population specific predictive equations have to be developed for the assessment of body composition, especially in a multicultural society using indirect methods such as BIA or anthropometry.

“…LBM in preschool-age children can, however, be estimated using suitable anthropometric equations and by bioelectric impedance analysis (NIH, 1994). In the present study we have measured the LBM in a group of urban preschool children belonging to low socio-economic group using bioelectrical impedance analysis (BIA) and anthropometric equations as validated earlier (Shaikh et al, 2002) for this population and investigated the pattern of percentage LBM (LBM%) in boys and girls.…”

Lean body mass in preschool aged urban children in India: gender difference

Objective: To estimate lean body mass (LBM) in preschool aged boys and girls in India and explore gender difference. Design: Crossectional. Setting: Immunization clinic of a charitable Government General Hospital in Kolkata, India. Subjects: Two-hundred and forty-five children (147 boys and 98 girls) aged 1 -5 y from among the urban poor were admitted in the study between July 1999 and December 2000. Children with acute or chronic illness or congenital malformation were excluded. Methods: Length=height to the nearest 0.1 cm, weight to the nearest 10 g and total body resistance using multifrequency bioelectrical (Xitron 4000B) impedance analyzer (BIA) at 50 kHz were measured. Their nutritional status was compared with National Center for Health Statistics (NCHS) median data and lean body mass (LBM) was calculated using anthropometry and BIA equations. The groups were compared using analysis of variance and multiple linear regression. Results: Girls were more stunted (P < 0.001) and underweight (P < 0.047), while the degree of wasting was similar. Mean LBM percentage was higher in boys compared with girls by anthropometry (P < 0.001) and BIA (P < 0.005), which persisted after adjusting for age. With increasing age, LBM percentage declined in girls (P < 0.02) in contrast to reference girls, in whom it increased. In boys LBM percentage increased with age as is in reference boys. Conclusions: In addition to the girls being more stunted and underweight, LBM% decreased in girls with increasing age but steadily increased in boys, suggesting hidden deprivation of female children.

“…They came from a low socioeconomic background. In addition, we measured height, weight (Shaikh et al, 2002;Gibson, 1990), BIA (Shaikh et al, 2002;Kabir et al, 1994;Khaled et al, 1988;Kushner, 1992;NIH, 1994;Sun et al, 2003), and also recorded the skinfold thicknesses (biceps, triceps, subscapular, and suprailiac) and midarm circumference (MAC) on these children. The methods for these additional measurements are described.…”

“…Traditionally, body fatness has been estimated for clinical or field use from measurements of skinfold thicknesses (de Meer et al, 1999;Schmelzle and Fusch, 2002), which correlate reasonably well with measurements by methods based on dual energy X-ray absorptiometry or D 2 O dilution (Pritchard et al, 1993;Salazar et al, 1994) in adults and older children. In the present study, we developed two new equations (one for boys and the other for girls) for preschool children using skinfold thickness (triceps and subscapular), midarm circumference (MAC), and age by comparing the results derived from equations based on anthropometry (height and weight) and BIA methods, which were validated previously (Shaikh et al, 2002) in a small number of children and applied by us in preschool children from among the urban poor in India (Shaikh et al, 2003). We then applied these equations to a small group of children to calculate %fat in whom this was also measured using a deuterium oxide (D 2 O) dilution method.…”

“…We then applied these equations to a small group of children to calculate %fat in whom this was also measured using a deuterium oxide (D 2 O) dilution method. Furthermore, we applied these equations on a separate group of boys and girls to estimate %fat and compared them with the estimates derived from anthropometry (Mellits and Cheek, 1970) and BIA (Fjeld et al, 1990) based equations used earlier (Shaikh et al, 2002).…”

We wanted to develop and apply new equations based on skinfold and midarm measurements for estimating %fat in preschool children suitable for field use. Prediction equations were developed on preschool-aged urban boys (n = 100) and girls (n = 84). Skinfolds at four sites and midarm measurements were regressed on %fat derived from equations based on height and weight and from bioelectrical impedance analysis (BIA; resistance at 50 kHz). These equations were applied: 1) to 12 children in whom the %fat was determined using D2O dilution, and 2) to 50 children in whom their %fat was derived using height-weight and BIA equations. The 95% limits of agreement (mean +/- 2 SD) for %fat derived by anthropometry and by new equations were within 1.7% in boys (r = 0.85; P < 0.001) and girls (r = 0.90; P < 0.001) and by BIA and new equations were within 1.5% in boys (r = 0.82; P < 0.001) and 2% in girls (r = 0.88; P < 0.001). For %fat measured by D2O dilution and new equations, 95% limits of agreement was within 1.3% (r = 0.98; P < 0.001). In 50 children 95% limits of agreement between anthropometry and new equations were within 1.8% in boys (r = 0.88; P < 0.001) and 1.4% in girls (r = 0.92; P < 0.001) and between BIA and new equations were within 1% in boys (r = 0.91; P < 0.001) and 1.5% in girls (r = 0.89; P < 0.001). The new equations for measuring %fat based on midarm circumference and skinfold measurements are rapid and accurate for South Asian children and should be useful for prediction of body composition and nutritional survey in field studies.
