北京市顺义区居民体重指数和腰围对血压的影响

Association between BMI and waistline with blood pressure among residents in Shunyi District, Beijing

目的 探讨北京市顺义区人群体重指数（BMI）、腰围、年龄及性别对血压的影响。方法 运用与人口规模成比例的概率抽样方法抽取18～79岁顺义区常住居民3840人,采用自行设计的调查问卷及体格测量表对调查对象进行面对面问卷调查和体格测量。结果 高血压患病率随着年龄的增高而增高,〈60岁组男性患病率明显高于女性,60岁以上组,男女性患病率差异无统计学意义;随着BMI值的增大,高血压患病率逐渐增高;腰围异常者高血压患病率亦高于腰围正常者,患高血压的风险增大（男性OR=2.329,95%CI：1.912～2.836;女性OR=4.806,95%CI：3.940～5.862）;体重指数正常组、超重及肥胖组中,腰围异常者高血压患病率均高于同组腰围正常者;BMI及腰围是高血压分级的影响因素。结论 应积极倡导健康生活方式,有效预防和控制超重、肥胖,降低高血压发病风险。

Objective To investigate the association of body mass index （BMI） and waistline with blood pressure among residents in Shnnyi District, Beijing. Methods Using Probability Proportional Sampling （PPS）, 3840 residents were investigated by face-to-face interview with a self-designed questionnaire and physical measurement. Results With in- creasing of age, the prevalence of hypertension was increased. The male prevalence of hypertension was higher than that of female among group aged less than 60 years. While among group age above 60 years, the difference of prevalence had no sta- tistical significance. With BMI increasing, the prevalence of hypertension was gradually increased. The hypertension preva- lence rates among residents with abnormal waistline were higher than those with normal waistline, their risk of high blood pressure was increased （male OR = 2. 329, 95% CI： 1. 912 - 2. 836 ; female OR = 4. 806, 95% CI： 3. 940 - 5. 862）. The prevalence of hypertension among residents with abnormal waistline was higher than those with normal waistline. BMI and waistline were the influencing factors of hypertension grading. Conclusion Healthy lifestyles should be promoted actively, preventing and controlling overweight and obesity effectively is important to reduce the risk of hypertension.
