The main objective of this paper was to determine the utility of various anthropometric measures to assess total and regional body fatness using dual-energy X-ray absorptiometry (DXA) as the criterion in 454 adolescent boys and girls aged 12-19 years. Multivariable regression analyses of gender-specific and gender-combined models were used to determine anthropometric measures on DXA-derived body fatness models, after adjusting for known confounding biological factors. Partial correlation analyses, after adjusting for age, pubertal growth status and ethnicity in boys and girls, showed that body mass index (BMI), waist circumference (WC), waist-to-hip ratio (WHR), and waist-height ratio (WhtR) were significantly correlated with total body fat (TBF), percent body fat (%BF), android region fat (ARF) and trunk fat (TF) (all p<0.0001). BMI was the greatest independent determinant, contributing 43.8%-80.9% of the total variance for DXA-derived body fatness models. Results confirmed that a simple anthropometric index such as the BMI is a good surrogate indicator of body fat levels in Malay and Chinese adolescents.
本文的主要目的是确定在454名年龄在12至19岁的青少年男孩和女孩中，以双能X线吸收法（DXA）为标准，各种人体测量指标评估全身和局部体脂的效用。在调整已知的混杂生物学因素后，使用性别特异性和性别组合模型的多变量回归分析来确定基于DXA得出的体脂模型的人体测量指标。在对男孩和女孩的年龄、青春期发育状况和种族进行调整后，偏相关分析表明，体重指数（BMI）、腰围（WC）、腰臀比（WHR）和腰高比（WhtR）与全身脂肪（TBF）、体脂百分比（%BF）、男性化区域脂肪（ARF）和躯干脂肪（TF）显著相关（所有p<0.0001）。BMI是最大的独立决定因素，对基于DXA得出的体脂模型的总方差贡献为43.8%-80.9%。结果证实，诸如BMI这样简单的人体测量指数是马来族和华裔青少年体脂水平的良好替代指标。
