3903例体检人群体质指数腰围与血压关系的研究

Analysis on the relationship between body mass index,waist circumference and blood pressure among 3903 physical check-up individuals

目的研究体质指数、腰围与血压水平以及高血压患病率之间的关系。方法采用整群抽样的方法,对2011年11月-2012年2月在中国人民解放军总医院国际医学中心进行体检的全部体检人群共计3 903人的血压、身高、体重和腰围（WC）进行测量,计算体质指数（BMI）。结果体重过低人群收缩压为（105.2±12.9）mm Hg,舒张压为（69.1±7.5）mm Hg;正常体重人群收缩压为（115.5±15.6）mm Hg,舒张压为（75.4±9.3）mm Hg;超重人群收缩压为（123.7±15.9）mm Hg,舒张压为（80.4±9.2）mm Hg;肥胖人群收缩压为（129.5±17.2）mm Hg,舒张压为（83.8±10.7）mm Hg。随着体质指数的增加,血压水平以及高血压患病率均逐渐增加,差异有统计学意义（P〈0.05）。腰围正常人群的收缩压为（114.4±16.0）mm Hg,舒张压为（74.5±9.6）mm Hg;腹型肥胖人群的收缩压为（124.3±16.5）mm Hg,舒张压为（80.8±9.6）mm Hg。腹型肥胖人群的血压水平和高血压患病率高于腰围正常人群,差异均有统计学意义（P〈0.05）。结论血压水平和高血压患病率与体质指数和腰围呈正相关。

Objective To explore the relationship between body mass index（BMI）,waist circumference（WC）and blood pressure. Methods Total of 3 903 individuals who came to the Health Management Institute of Chinese PLA General Hospital for physical check-up from November 2011 to February 2012 were selected by cluster sampling method into the study.Their blood pressure,height,weight and waist circumference were measured and BMI was calculated. Results Both SBP and DBP gradually increased from（105.2±12.9）and（69.1±7.5）mm Hg among individuals with low body weight to（129.5±17.2）and（83.8±10.7）mm Hg among individuals with obesity.Meanwhile,the SBP and DBP of individuals with normal WC were（114.4±16.0）and（74.5±9.6）mm Hg,and were（124.3±16.5）and（80.8±9.6）mm Hg among individuals with high WC.The blood pressure and the incidence of hypertension increased along with the rise of BMI and WC（P0.05）. Conclusions Blood pressure and the incidence of hypertension are positively correlated with BMI and WC.
