中国成人腰围、体质指数与高血压关系

目的 采用腰围(WC)、体质指数(BMI)综合评价中国18～69岁成年人中心性肥胖者高血压患病风险。方法 利用2004年中国慢性病及其危险因素监测样本人数,采用多级抽样方法抽取18～69岁成年人30686人,采用问卷调查和人体测量方法收集数据,比较各BMI组别中心性肥胖者高血压患病的OR值。结果 体质指数正常、超重和肥胖组中,男性中心性肥胖者高血压患病率分别为26.1%,32.0%和49.2%;女性中心性肥胖者高血压患病率分别为22.5%,28.2%和41.5%;除男性肥胖组外,中心性肥胖者高血压患病率均明显高于同组内的正常腰围人数(P<0.01);调整混杂因素(年龄、吸烟状况、饮酒状况和锻炼等)后,与正常腰围人群比较,各BMI组别中男性中心性肥胖者患高血压患病的OR值分别为1.9(95%CI=1.6～2.3),1.6(95%CI=1.3～1.9),1.6(95%CI=0.7～3.7);女性患高血压患病OR值分别为1.5(95%CI=1.3～1.8),1.4(95%CI=1.2～1.6),2.5(95%CI=1.2～5.2)。结论 中心性肥胖者与正常腰围者比较具有更高的高血压患病风险。

Analysis on association of waist circumstance and body mass index with risk of hypertension in Chinese adults

Objective To evaluate whether the risk of hypertension in individuals with central obesity is high than those with nounal waist cireum ference (WC) within the sam a body mass index (BMI) categories.Methods Questionnaire and body measurem entwere used to collecte data 30,686 adults participated in Chinese Chronic Disease and Risk Factors Surveillance (2004) were included in the analysis and grouped by BMI and WC.Odds ratio for hypertension was computed within nouna by eight(18.5-23.9),overiveight(24.0-27.9) and obesity(≥28) BMI category and subjects with noun al WC and abdomen obesity were compared.Results Within noun alweight and ovemveight BMI categories,compared with those with nounal WC,male subjects with central obesity had higher prevalence rates of hypertension (26.1%,32.0% and 49.2%,respectively; P<0.0l) and higher hypertension risk(adjusted ORs=1.9 and 1.6,respectively; P<0.01).Within the three BMI categories,female subjects with central obesity had higher prevalence rate of hypertension (22.5%,28.2% and 41.5; P<0.01) andhigherhypertensionrisk(adjusted ORs=1.5,1.4 and 2.5; P<0.05).Conclusion The risk of hypertension in individuals with central obesity is high than those with nounal waist circum ference within three BMI categories.
