目的：NIH临床指南（1998）建议测量腰围体重指数内（WC，厘米）（体重指数，千克每平方米）类别作为筛选工具增加健康风险。研究方法和程序：加拿大心脏健康调查（1986年至1992年）被用来描述加拿大代谢综合征的患病率，并测试使用NIH指南预测代谢危险因素。样本包括7981名年龄在20到74岁之间的参与者，他们有完整的WC，BMI，高密度脂蛋白胆固醇，甘油三酯，糖尿病状态，收缩压和舒张压数据。使用国家胆固醇教育计划成人治疗小组III风险类别来确定代谢综合征和相关风险因素。采用Logistic回归检验WC可提高超重（25 ~ 29.9 kg/m2）和肥胖I（30 ~ 34.9 kg/m2）BMI类别中代谢综合征的预测能力的假设。与低WC的超重和肥胖女性相比，高WC的超重和肥胖女性预测代谢综合征的比值比（OR）分别升高[OR，1.85; 95%可信区间（95%CI），1.02 - 3.35]和肥胖（OR，2.35; 95%CI，1.25 - 4.42）。另一方面，WC是没有预测的代谢综合征或成分的危险因素在男性中，BMI categories.Discussion：在妇女已经在增加健康风险，因为BMI升高，WC的额外测量可能有助于确定心血管疾病的风险。
Objective: NIH Clinical Guidelines (1998) recommend the measurement of waist circumference (WC, centimeters) within body mass index (BMI, kilograms per square meter) categories as a screening tool for increased health risk.Research Methods and Procedures: The Canada Heart Health Surveys (1986 through 1992) were used to describe the prevalence of the metabolic syndrome in Canada and to test the use of the NIH guidelines for predicting metabolic risk factors. The sample included 7981 participants ages 20 to 74 years who had complete data for WC, BMI, high-density lipoprotein-cholesterol, triglycerides, diabetic status, and systolic and diastolic blood pressures. National Cholesterol Education Program Adult Treatment Panel III risk categories were used to identify the metabolic syndrome and associated risk factors. Logistic regression was used to test the hypothesis that WC improves the prediction of the metabolic syndrome, within overweight (25 to 29.9 kg/m(2)) and obese I (30 to 34.9 kg/m(2)) BMI categories.Results: The prevalence of the metabolic syndrome was 17.0% in men and 13.2% in women. The odds ratios (OR) for the prediction of the metabolic syndrome were elevated in overweight [OR, 1.85; 95% confidence interval (95%CI), 1.02 to 3.35] and obese (OR, 2.35; 95%CI, 1.25 to 4.42) women with a high WC compared with overweight and obese women with a low WC, respectively. On the other hand, WC was not predictive of the metabolic syndrome or component risk factors in men, within BMI categories.Discussion: In women already at increased health risk because of an elevated BMI, the additional measurement of WC may help identify cardiovascular risk.
