目的了解天津市社区成年人超重、肥胖与高血压患病率的关系,为制定相应的干预措施提供科学依据。方法按分层整群随机抽样方法,于2007年9月—2009年7月抽取天津市内18岁及以上23 533名常住居民进行调查。结果高血压患病率有随BMI增高而增高的趋势,正常体重组、超重组和肥胖组的高血压患病率分别为20.1%,37.5%和52.2%,青年人中超重、肥胖者患高血压风险更大(男性OR值分别为2.737和5.236;女性OR值分别为3.744和7.360),大于中年组(男性OR值分别为1.913和4.090;女性OR值分别为2.099和3.942)和老年组(男性OR值分别为1.671和2.848;女性OR值分别为1.674和2.685)。结论与正常体重相比,超重和肥胖者患高血压危险增加。控制青年人群的超重和肥胖的发生率对于降低该人群的高血压患病水平有重要意义。
Objective To understand the relationship between overweight, obesity and the prevalence of hypertension among community adults in Tianjin and to provide a scientific basis for formulating appropriate interventions. Methods According to stratified cluster random sampling method, from September 2007 to July 2009, 23 533 permanent residents aged 18 years and over in Tianjin were sampled for investigation. Results The prevalence of hypertension tended to increase with the increase of BMI. The prevalence of hypertension in normal weight group, overweight group and obesity group were 20.1%, 37.5% and 52.2%, respectively. The prevalence of overweight and obesity in young people was high (OR = 2.737 and 5.236, respectively; OR = 3.744 and 7.360, respectively), which were significantly higher than those in middle age group (male OR = 1.913 and 4.090; female OR = 2.099 and 3.942, respectively) (Male OR values were 1.671 and 2.848, respectively; female OR values were 1.674 and 2.685, respectively). Conclusion Compared with normal body weight, the risk of hypertension in overweight and obese people increases. Controlling the incidence of overweight and obesity in young people is important for reducing the prevalence of hypertension in this population.
