Body weight (BW), body mass index (BMI), skinfolds measurement (SKF), and bioelectrical impedance analysis (BIA) are widely used field methods in evaluating body composition. The associations of these body composition measurements with the criterion of body fat were documented extensively in adult population. However, few comparison studies were found for Chinese children. The existing SKF (Slaughter et al., 1988) and BIA prediction equations (Kim et al., 1993; Watanabe et al., 1993) for children have not been cross-validated in Chinese children. The purpose of this study was to evaluate the BW, BMI, SKF, and BIA in predicting %fat in Hong Kong Chinese children. Chinese children age 8 to 12 (42 girls, age = 10.33 [+ or -] 1.15 years; 32 boys, age = 10.66 [+ or -] 1.28 years) recruited from local primary schools participated in this study. All children participated in BW, BMI, SKF, and BIA measurement following standard procedures. The body fat criterion was measured by hydrostatic weighing, in which the resid ual volume was measured using the oxygen dilution method. Zero-order correlations (see below) found that most body composition measurements yielded high correlations with %fat criterion, except impedance (Z) and estimated %fat derived from BIA.

Highest r was found in BW for girls and in BMI for boys. Lowest r were found for BIA and Z. Multiple regression analysis revealed that the 2-site skinfolds equations produced relatively large standard errors (6. …
