To examine the relative contribution for the prediction of hypertension by waist circumference (WC), waist:stature ratio (WSR) or waist:hip ratio (WHR) with that by BMI, to ascertain if WC, WSR or WHR enhances the prediction of hypertension by BMI.
Population-based, cross-sectional study. A change of >or=10 % in the prevalence ratio of BMI (PR) or the area under the receiver-operating characteristic curve (AUC) when WC, WSR or WHR was added to a model with BMI was used as the criterion for significant contribution to the prediction of hypertension by BMI. For greater contributions (>or=10 %) these waist measures were considered as better predictors.
Nine provinces in China.
Chinese adults aged 18 to 65 years (n 7336) who participated in the 2004 China Health and Nutrition Survey.
The prevalence of hypertension (17 % and 23 % for women and men, respectively) was significantly related to increased BMI, WC, WSR and WHR (P for trend <0.001). Although there was a better model fit when WC, WSR or WHR was added to a model with BMI (P < 0.05; likelihood ratio test), the changes in PR and AUC were <10 % and <5 %, respectively. The sex-specific AUC for the prediction of hypertension by BMI (of 0.7-0.8) was similar to that by WC, WSR or WHR.
The waist indices do not perform better than BMI or markedly enhance the prediction of increased hypertension risk by BMI in Chinese adults.
探讨腰围(WC)、腰高比(WSR)和腰臀比(WHR)对高血压预测的相对贡献,以确定 WC、WSR 或 WHR 是否能增强 BMI 对高血压的预测作用。
基于人群的横断面研究。当 WC、WSR 或 WHR 加入到包含 BMI 的模型中时,如果 BMI 的患病率比(PR)或受试者工作特征曲线(ROC)下面积(AUC)的变化大于等于 10%,则认为其对 BMI 预测高血压有显著贡献。如果这些腰围指标的贡献大于等于 10%,则认为其对高血压的预测作用更好。
中国 9 个省份。
参加 2004 年中国健康与营养调查的年龄在 18 至 65 岁之间的中国成年人(n=7336)。
高血压的患病率(女性和男性分别为 17%和 23%)与 BMI、WC、WSR 和 WHR 的增加呈显著相关(P<0.001)。虽然当 WC、WSR 或 WHR 加入到包含 BMI 的模型中时,模型拟合得到改善(P<0.05;似然比检验),但 PR 和 AUC 的变化小于 10%和 5%,分别。BMI 预测高血压的性别特异性 AUC(0.7-0.8)与 WC、WSR 或 WHR 相似。
在中国成年人中,腰围指数并不比 BMI 表现更好,也不能显著增强 BMI 对高血压风险增加的预测作用。
