应用生物电阻抗（BIA）法测定314名部队士兵的人体成分。年龄（20．3±1．5）岁，身高（171．2±5．7）cm，体重（61．8±6．9）kg，体质指数（BMI）21．1±2．1，瘦体（L）（55．2±5．8）kg，L占体重（89．6±7．1）％，脂肪（F）（6．6±4．9）kg，F占体重（10．4±7．1）％；BIA、理想体重和BMI三种方法对肥胖的检出率分别为8．3％，36．2％和6．7％，BIA法与理想体重法有非常显著性差异，BIA法与BMI法差异不显著，但两者一致性较差；年龄、体重、电阻抗（Z）、BMI、F与F％为非常显著性正相关。结果提示：（1）部队士兵随着年龄的增高，F有增多的趋势；（2）受试人群营养状况良好，锻炼强度适宜；（3）理想体重法与BMI法判断肥胖，不适用于全训部队士兵。
The bioelectrical impedance (BIA) method was used to determine the body composition of 314 troops. The age (20.3 ± 1.5) years old, height (171.2 ± 5.7) cm, body weight (61.8 ± 6.9) kg, body mass index (BMI) 21.1 ± 2.1, Body weight (L) (55.2 ± 5.8) kg, L body weight (89.6 ± 7.1)%, F (6.6 ± 4.9) 4 ± 7.1)%. The detection rates of obesity by BIA, ideal body weight and BMI were 8.3%, 36.2% and 6.7% respectively. There was a significant difference between BIA and ideal body weight There was no significant difference between BIA and BMI, but the consistency was poor. Age, weight, electrical impedance (Z), BMI, F and F% were highly significant positive correlation. The results suggest that: (1) F soldiers have an increasing trend with age; (2) the nutritional status of the test subjects is good and exercise intensity is appropriate; (3) the ideal body weight method and the BMI method determine the obesity and are not applicable to the whole Training soldiers.
