摘要：
This study compared body mats index (BMI) and inverted BMI (IBMI) as predictors Of body fatness in 177 Portuguese children (149 girls and 96 boys) aged 7-16 years. Participants undertook measures of height and body mass from which BMI (kg/m(2)) and iBMI (cm(2)/kg) were determined. Maturation was detertnined via self-report and fat mass index (FMI, kg/m(2)) via dual-energy X-ray absorptiometry. Significant relationships were evident between BMI and iBMI and FMI (both P = 0.0001). BMI was not normally distributed (P = 0.0001) but iBMI was (P > 005). Analysis of covariance identified that BMI and iBMI, controlling for maturation, were both significant predictors of FMI (both P = 0.0001) but that iBMI predicted a slightly greater amount of the variance (adjusted R-2 = 0.970) compared with BMI (adjusted R-2 = 0.968). This study suggests that iBMI is a similar proxy for body fattiest compared with BMI in children.
