ObjectiveTo 学习为在 China.MethodsA 的山东省在中年、老的题目识别新陈代谢的风险因素的截止价值 2 873 个男人和 5 559 个女人总计的最佳的腰圆周(WC ) 在这代表性的研究被包括。新陈代谢的症候群(MetS ) 在 2004 根据中国糖尿病社会的定义被诊断。在 WC 和 MetS 之间的关系被 multivariate 分析逻辑回归分析。最佳的 WC 截止价值在 ROC 曲线下面用区域被识别,为中央肥胖的不同诊断标准是 compared.ResultsThe WC 是为独立于 BMI,血葡萄糖,血类脂化合物,和血压的 MetS 的风险因素。最佳的 WC 截止价值为分别地在女人和男人识别 MetS 是 83.8 厘米和 91.1 厘米。与为女人和男人的 80 厘米和 85 厘米相比, 85 厘米和 90 厘米为鉴别在女人和 men.ConclusionThe 的所有新陈代谢的风险因素和 MetS 拨出有一个更高的 Youden 索引 WC 截止价值为在中国的山东省在女人和男人识别中央肥胖和 MetS 是 85 厘米和 90 厘米。
Objective To study the optimal waist circumference (WC) cut-off values for identifying metabolic risk factors in middle-aged and elderly subjects in Shandong Province of China. Methods A total of 2 873 men and 5 559 women were included in this cross-sectional study. Metabolic syndrome (MetS) was diagnosed according to the definition of Chinese Diabetes Society in 2004. The relation between WC and MetS was analyzed by multivariate logistic regression analysis. The optimal WC cut-off values were identified using the area under the ROC curve and the different diagnostic criteria for central obesity were compared. Results The WC was the risk factor for MetS independent of BMI, blood glucose, blood lipid, and blood pressure. The optimal WC cut-off value was 83.8 cm and 91.1 cm for identifying MetS in women and men, respectively. Compared with 80 cm and 85 cm for women and men, 85 cm and 90 cm had a higher Youden index for identifying all metabolic risk factors and MetS in women and men. Conclusion The appropriate WC cut-off value is 85 cm and 90 cm for identifying central obesity and MetS in women and men in Shandong Province of China.
