摘　　要：目的:探讨成人诊断代谢综合征的适宜体质指数切点。方法:以2008-2009年南京地区参加健康体检成人27822人为研究对象,测量身高、体重、血压,采集空腹静脉血测定葡萄糖、血甘油三酯、高密度脂蛋白胆固醇,通过对体质指数和各代谢异常危险因素的分析,建立受试者工作特征曲线(ROC曲线),探讨适宜的体质指数诊断切点。结果:男性出现代谢异常危险因素的比例高于女性;根据ROC曲线分析,在男性BMI为24.32、女性BMI为23.06时,预测≥2项代谢异常危险因素的Youden指数最大。结论:南京地区成人代谢综合征的体质指数切点,以男性BMI=24,女性BMI=23比较合适。Objective：To study the optimal cutoff point of body mass index （BMI） for identifying the metabolic syndrome in adults. Methods： Based on data of 27 822 people received routine annual health examinations in a hospital of Nanjing during 2007 - 2008, the relationship between BMI and metabolic risk factors was analyzed, and receiver operating characteristic curves （ROC curve）were built to estimate the optimal cutoff points of BMI. Results：The proportion of the risk factors of metabolic abnormality was higher in men than in women. Based on ROC curves analysis and Youden index, the BMI value for predicting two or more metabolic risk factors was 24.32 for men and 23.06 for women. Conclusion ：The appropriate BMI cutoff point for the metabolic syndrome was determined to be 24 for man and 23 for women in adults of Nanjing residents.
