We examined the relationship between body fat and body mass index (BMI) in a multiethnic population of obese children. BMI z-scores were compared to DEXA measures of whole body composition and regional fat distribution. Fat mass index (FMI) was best predicted by the equation: 1/[(0.159- 0.013 x percentile of total abdominal fat)- (0.01 x BMI z-score)], where percentile of abdominal fat ranges from 1 to 5. Predicted FMI had high agreement with FMI measured by DEXA. There were no detectable differences in this relation between different ethnic groups. Both BMI and abdominal fat should be used as a proxy to determine adiposity.
我们在一个多民族肥胖儿童群体中研究了体脂与体重指数（BMI）之间的关系。将BMI z评分与双能X线吸收法（DEXA）测量的全身成分和局部脂肪分布进行比较。脂肪量指数（FMI）的最佳预测方程为：1/[（0.159 - 0.013×腹部总脂肪百分比）-（0.01×BMI z评分）]，其中腹部脂肪百分比范围为1至5。预测的FMI与DEXA测量的FMI高度一致。不同种族群体之间在这种关系上没有可检测到的差异。BMI和腹部脂肪都应用作确定肥胖程度的替代指标。
