中年知识分子体重指数、腰围及腰臀比与高血压发生的风险性分析

The Purposed Value of Body Mass Index, Waist Circumference and Waist to Hip Ratio Used as Indexes Predicting Hypertension in Middle-age Intellectuals

目的 :了解体重指数 (BMI)、腰围 (WC)及腰臀比 (WHR)对人群高血压发生的风险性的价值。方法 :对广州市 1191名 35～ 6 5岁知识分子进行身高、体重、腰围、臀围及血压的测量。用直线相关分析BMI、WC和WHR与收缩压和舒张压的关系 ;将BMI、WC和WHR分别根据最大和最小值分成 3等份 ,分析 3个指标对高血压患病率的影响 ;分析三个指标对高血压发生的风险性预测的价值。结果 :男女血压水平及高血压患病率均随BMI、WC和WHR的增加而上升 (P值均 <0 .0 5 ) ;对血压影响的贡献的次序为 :体重指数 >腰围 >腰臀比 ;BMI≥ 2 5、腰围≥ 85cm、女性腰臀比≥ 0 .95可作为预测高血压危险性的诊断建议值。结论 :BMI、WC和WHR是预测高血压危险性的有效指标 ;控制BMI、WC和WHR可以有效地防治高血压。

Objective:To study the relationship between body mass index (BMI), Waist circumference(WC)and waist hip ratio(WHR) and blood pressure in population. Method: A total of 1191 people from 35 years old to 65 years old intellectuals in Guangzhou were surveyed. Height, weight, waist circumference, hip circumference and blood pressure were measured. The effects of WHR, WC and BMI on the average blood pressure and the prevalence of hypertension in crowd were analyzed by dividing WHR,WC and BMI into trisect. Result: The average blood pressures level and the prevalence of hypertension of male and female were increased significantly with the increase of BMI as well as with the increase of WC and also WHR (P<0.05). Conclusion: BMI,WC and WHR are valid indices to predict the hypertension risks. Controlling BMI,WC and WHR can effectively prevention and cure hypertension.
