OBJECTIVE
Knowing the percent of the body fat in the Chinese young and doing some basic works of making the fat mass criteria of the Chinese children obesity and prevention of the obesity in the young children.
METHODS
2445 children (1257 males and 1188 females) from Beijing and Guangzhou were studied. All of them underwent anthropometrical measurements and bioelectrical impedance analysis (BIA). By applying Chinese children fat mass predict equation to estimate their FFM. The percent of fat mass was calculated by subtracting FFM from weight (Wt).
RESULTS
The body fat percent increase with the age increase both in boys and girls. There is gender different between boys and girls. The boys' BF(%) is higher than in the girls'. The boys and girls' BF(%) in Beijing are higher than boys and girls' BF(%) in Guangzhou. At the same growth degree with the ages increase the BF(%) decrease; while at the same age, with growth increase, BF(%) decrease both in boys and girls.
CONCLUSION
The BF(%) is different between the ages, area, and gender and growth degree.
目的
了解中国青少年的体脂百分比，为制定中国儿童肥胖的体脂量标准及预防幼儿肥胖做一些基础工作。
方法
对来自北京和广州的2445名儿童（1257名男性和1188名女性）进行了研究。他们全部接受了人体测量和生物电阻抗分析（BIA）。通过应用中国儿童体脂量预测方程来估算他们的去脂体重（FFM）。体脂百分比通过体重（Wt）减去去脂体重来计算。
结果
男孩和女孩的体脂百分比均随年龄增长而增加。男孩和女孩之间存在性别差异。男孩的体脂百分比（BF(%)）高于女孩。北京男孩和女孩的BF(%)高于广州男孩和女孩的BF(%)。在相同生长程度下，随着年龄增长BF(%)下降；而在同一年龄，随着生长增加，男孩和女孩的BF(%)均下降。
结论
BF(%)在年龄、地区、性别和生长程度之间存在差异。
