目的研究我国蒙古族农牧民代谢综合征(MS)诊断的腰围(WC)适宜切点。方法以内蒙古自治区通辽市科左后旗朝鲁吐苏木和奈曼旗固日班化苏木32个自然村2589名年龄大于20岁的蒙古族农牧民为研究对象,以国际糖尿病联盟(IDF)MS全球共识诊断标准为基础,分析蒙古族男女不同WC水平与MS其他组分聚集的关联,检出至少两个组分存在时灵敏度和特异度均较高的WC界限,作为诊断蒙古族农牧民MS的WC切点,并以此计算不同年龄组MS的检出率。结果随WC增大,MS组分聚集的OR值显著增高。当男性WC≥84 cm、女性WC≥81 cm时,ROC曲线下面积最大。结论 IDF标准在蒙古族农牧民男性中WC切点偏高,宜降至男性≥85cm、女性≥80cm。
Objective To study waist circumference (WC) suitable point of diagnosis of metabolic syndrome (MS) in Mongolian nationality in China. Methods A total of 2589 Mongolian herds and herdsmen aged over 20 years in 32 natural villages of Lu Mu and Naiman Qi solid-day classes in Tongliao City, Inner Mongolia Autonomous Region were enrolled in this study. The International Diabetes Federation (IDF) ) MS Global Consensus Diagnostic Criteria, the association of different WC levels in Mongolian men and women with the aggregation of other MS components was analyzed, and a WC limit of higher sensitivity and specificity in the presence of at least two components was detected as a diagnostic tool for Mongolian farmers Herdsman MS cut point of WC, and to calculate the MS detection rate of different age groups. Results With the increase of WC, the OR of aggregation of MS components increased significantly. When the male WC ≥ 84 cm, female WC ≥ 81 cm, the area under the ROC curve is the largest. Conclusion The IDF standard is high in the point of WC in Mongolian farmers and herdsmen, and should be reduced to ≥85cm in male and ≥80cm in female.
