农村中老年人血压水平与体质指数和腰臀比的关系

为了解体质指数(BMl)和腰臀比(WHR)对人群血压水平的影响,对河南、安徽、北京农村12995名40岁及以上中老年男女进行了身高、体重、腰围、臀围及血压的测量.将BMI和WHR分别根据最小和最大值分成3等份,分析BMI、WHR及两者相结合对人群平均血压水平及高血压患病率的影响.结果:BMI与男女平均血压水平和高血压患病率均呈明显正相关(P<0.01);BMI和WHR同时增加对平均血压水平和高血压患病率的上升影响更为明显(P<0.01);WHR≥0.76时男女调查对象的平均血压及高血压患病率均不再随着WHR的增加而上升(P>0.05),提示WHR≥0.80可作为预测高血压危险性的界限值.我们认为:BMI和WHR相结合是预测高血压危险性的有效指标;控制BMI和WHR可以有效地防治高血压.

The Relationship Between BMI and WHR and Average Blood Pressure levels of Middle and Elderly People in Rural China

To Study the relationship between BMI and WHR and blood pressure,A total of 12,995 people over 40 years of age in rural China was surveyed.Height,weight,waist circumference,hip circumference and blood pressure were measured.The relationship betwween BMI and WHR and blood pressure were analyzed by dividing BMI and WHR into tertiles.Results:The average blood pressure level and the prevalence of hypertension of male and female are increased significantly with the increase of BMI(P< 0.01)as well as with the increase of BMI and WHR simultanceously(P<0.01).The average blood pressure and prevalence of hypertension did noth increase when WHR≥0.76(P>0.05),and this suggest that WHR≥0.80 may as a cut-off value for hypertension risks prediction.We believe that the combination of BMI and WHR is an effective indicator for the prediction of hypertension risks,and hypertension can be effectively prevented and controlled by controlling BMI and WHR.
