摘要
目的探讨社区中老年人代谢综合征（MS）中腰围的适宜切点。方法利用2005至2007年对上海市长风社区糖尿病高危人群筛查所调查的1558例40-79岁社区居民资料，分析男性和女性不同腰围水平检出腰围以外的2个及2个以上MS组分的敏感度和特异度，采用受试者工作特征（ROC）曲线寻找适宜腰围切点。结果根据ROC曲线，检出多个MS组分的适宜腰围切点，男性为85．0cm，女性为80．0cm，敏感度分别为72．3％和74．9％，特异度分别为50．2％和62．2％。以该切点为基础，参照国际糖尿病联盟的MS诊断工作定义，该人群MS的检出率为38．8％，其中男性40．7％、女性37．8％。结论上海市社区中老年人群MS适宜腰围切点为男性≥85．0cm、女性≥80．0cm。
Objective To explore an optimal cut-off value of waist circumference （WC） for identifying metabolic syndrome （MS） in middle-aged and elder residents in an urban community. Methods Database of 1558 residents aged 40 - 79 years at high-risk in screening for diabetes from Changfeng community, Putuo District, Shanghai during 2005 to 2007 was used to analyze sensitivity and specificity of varied cut-off values of WC for identifying two or more components of MS in men and women, respectively. Receiver operating characteristics （ROC） curve was used to explore the optimal value. Results Optimal cut-off value of WC was 85.0 cm for men and 80. 0 cm for women, respectively, for identifying two or more components of MS by ROC curve, with sensitivity of 72. 3% and 74. 9%, and specificity of 50. 2% and 62.2%, respectively. Based on that optimal cut-off value of WC and definition of International Diabetes Federation （ IDF）, prevalence of MS was 38.8% in this population, 40. 7% in men and 37.8% in women, respectively. Conclusion The optimal cut-off value of WC was 85.0 cm in men and 80.0 cm in women, respectively, for identifying MS in the middle-aged and elderly in an urban community of Shanghai.
