背景：成人躯干肥胖对健康有不良影响，但在中国缺乏正确测量躯干肥胖的有效和实用的方法。目的：本研究旨在评估人体测量指标作为筛查中国年轻人躯干肥胖预测因素的有效性。对象与方法：共招募20 ~ 40岁的中国志愿者1946人（女性853人，男性1093人）。躯干脂肪量采用双能x线吸收仪测定。测量或计算体重指数（BMI）、腰围（WC）、腰臀比（WHR）和锥度指数（C指数）。采用受试者工作特征（ROC）曲线比较各人体测量指标预测躯干肥胖的有效性。结果：BMI和WC作为界定躯干肥胖的人体测量指标优于WHR和C指数，BMI（男性0.94，女性0.89）和WC（男性0.93，女性0.88）的ROC曲线下面积相似。结论：BMI和WC比WHR和C指数更能有效预测中国青壮年躯干肥胖。
Background: Trunk obesity has adverse health implications in adults, but valid and practical methods to correctly measure trunk obesity in China are insufficient.Aim: This study aimed to assess the validity of anthropometric indices as screening the predictors of trunk obesity in young Chinese adults.Subjects and methods: A total of 1946 (853 women, 1093 men) Chinese volunteers aged 20-40 years were recruited. Trunk fat mass was measured by dual-energy X-ray absorptiometry. Body mass index (BMI), waist circumference (WC), waist-to-hip ratio (WHR) and conicity index (C index) were measured or calculated. Receiver operating characteristic (ROC) curves were used to compare the validity of each anthropometric index to predict trunk adiposity.Results: BMI and WC performed better as the anthropometric indices defining trunk obesity than WHR and C index, and the areas under the ROC curves for BMI (0.94 in men and 0.89 in women) were similar to those for WC (0.93 in men and 0.88 in women).Conclusions: Both BMI and WC are more effective predictors of trunk obesity than WHR and C index in Chinese young adults.
