中国成年人体质指数与血压关系的探讨

利用 1992年全国营养调查中的体格测量资料 ,选取 2 0岁以上的成人作为研究对象 ,探讨我国成人体质指数的分布状况及与血压的关系 ,并拟为确定我国居民的适宜BMI参考值提供一定的参考资料。结果表明 ,我国成人体质指数的分布存在明显的年龄、性别及城乡差异 ;平均收缩压和平均舒张压均随着BMI的增加呈逐渐上升的趋势 ,多元线性回归分析显示BMI对血压值存在明显的线性关系 ;控制年龄、性别及城乡等混杂因素后 ,Logistic回归分析显示体质指数对高血压发生的相对危险度随着BMI值的增加大体呈升高趋势

Study on the relationship between body index and blood pressure in Chinese adult

the authors use the anthropometry data of the Third National Nutrition Survey in China, and select the adult above 20 year old as the study subjects in order to study the relationship between BMI and blood pressure value and to provide some reference data for defining the suitable BMI cut off point of overweight and obesity in Chinese adult. The results show that the distribution of BMI varied with sex, age and areas;mean levels of systolic and diastolic blood pressure both gradually increased as BMI increased, multifactor linear regression analyses indicates there is obvious linear relationship between blood and BMI;The associations of BMI with high blood pressure were statistically significant after controlling for age, sex, area or smoking, logistic regression analyses indicate that odds ratios increased gradually at the different levels of BMI. These data quantify the strong associations of BMI with hypertension.
