男性人体测量指标与体脂含量相关性分析

Analysis of the Relationship Between Anthropometric Measurements and Body Fat Content in Men

[目的]探讨男性人体测量指标与体脂含量的相关性.[方法]选取 20～50岁男性 89例为研究对象,根据体重指数分为 3组.应用双能X线进行体脂含量测定.[结果]超重组和肥胖组体脂含量,总体脂肪质量和躯干脂肪质量均高于对照组（P〈0.05）.体脂含量与体重指数（r =0.765）,腰围（r =0.798）,腰围身高比（r =0.809）和腰臀比（r =0.665）均呈正相关（P〈0.01）.以体脂含量为因变量,行多元线性回归显示,腰围身高比（β=93.983,P=0.000,R2=0.654）被引入方程.[结论]男性人体测量指标与体脂含量密切相关,利用简单的人体测量指标推算体脂含量是可行的,但有待流行病学研究进一步证实.

[Objective]To explore the relationship between anthropometric measurements and body fat content in men. [Methods] Totally 89 men aged 20450 years old were enrolled in this study. According to body mass index, these men were assigned to 3 groups. Body fat content was measured by dual-energy X-ray absorptiometry. [Results] Body fat content, total body fat mass and trunk fat mass in overweight and obese group were higher than those in control group（ P〈0.05）;. Body fat content was positively correlated with body mass index（r =0. 765）, waist circumference（r ：0. 798）, waist to height ratio（r =0. 809） and waist to hip ratio（r =0. 665）（ P 〈0. 01）. Multiple linear regression analysis showed that waist to height ratio （β= 93. 983, P = 0. 000, R^2 = 0. 654） was the independent predictor for body fat content. [Conclusion] Anthropometric measurements in men are closely correlated with body fat content in men. Simple anthropometric measurement for estimating body fat content is feasible, but should be further confirmed by epidemiological studies.
