In the modified ATP III definition for metabolic syndrome (MS), the cut-off values for central obesity were set to > or =90 cm for male and > or =80 cm for women. Recently, a new Chinese definition for central obesity was set to > or =90 cm for male and > or =85 cm for women according to the corresponding BMI value of 25 kg/m(2).
The purpose of this study was to explore the optimal WC cut-off points to reflect the cluster of multiple risk factors for adults in Beijing.
The data collected during the surveillance of risk factors for non-communicable diseases in Beijing 2005 were used, with a total of 16,711 adults studied. Subjects with two or more components from the modified ATP III definition other than central obesity were considered to have multiple risk factors.
The optimal WC cut-off points were 87 cm in men and 80 cm for women. When applied the WC advised definition for MS, the age-standardized prevalence was 38.0% for male and 32.3% for women, which is significantly higher than using the original one for men (34.7% vs 32.3%, P<0.001).
The present study indicated that optimal waist circumference cut-off points were lower than that proposed in the modified ATP III definition, especially for men.
在代谢综合征（MS）的改良 ATP III 定义中，中心性肥胖的截断值设定为男性>或=90cm，女性>或=80cm。最近，根据相应的 BMI 值 25kg/m²，中国制定了一个新的中心性肥胖定义，男性>或=90cm，女性>或=85cm。
本研究旨在探讨反映北京成年人多种危险因素聚集的最佳 WC 截断点。
使用 2005 年北京非传染性疾病危险因素监测收集的数据，共研究了 16711 名成年人。被认为有多种危险因素的受试者除中心性肥胖外，还具有改良 ATP III 定义中的两个或两个以上组成部分。
男性最佳 WC 截断点为 87cm，女性为 80cm。当应用建议用于 MS 的 WC 定义时，男性和女性的年龄标准化患病率分别为 38.0%和 32.3%，显著高于男性使用原始定义的患病率（34.7%比 32.3%，P<0.001）。
本研究表明，最佳腰围截断点低于改良 ATP III 定义中提出的截断点，尤其是男性。
