玉环县农村社区≥35岁居民超重和肥胖及其与高血压的关系

The association of overweight and obesity with hypertension among residents aged 35 years or older in Yuhuan county

目的了解浙江省玉环县农村社区≥35岁居民超重和肥胖流行现状,探索超重、肥胖与高血压患病的关系。方法 2009-2010年,采用整群抽样方法在玉环县所有农村社区中抽取124 693名≥35岁常住居民进行横断面调查,分析超重和肥胖与高血压患病之间的关系。结果玉环县农村社区≥35岁居民超重和肥胖率分别为34. 53%和10. 18%。其中男性超重率(35. 56%)高于女性(33. 66%),女性肥胖率(11. 26%)高于男性(8. 90%),差异均有统计学意义(均有P <0. 05)。多因素分析显示:年龄、是否务农、教育程度、规律体育锻炼、吸烟、饮酒和高盐饮食等均为超重/肥胖的可能影响因素(均有P <0. 05)。在调整可能的混杂因素后,非条件Logistic回归分析结果显示:男性超重和肥胖者患高血压的风险分别是体重正常人群的2. 02(95%CI:1. 93～2. 11)和3. 83 (95%CI:3. 57～4. 10)倍;女性分别为1. 94 (95%CI:1. 86～2. 02)和3. 56(95%CI:3. 35～3. 77)倍。结论玉环县农村社区≥35岁居民超重和肥胖患病率较高,且超重和肥胖可能增加高血压的患病风险。

Objective To assess the prevalence of overweight and obesity among residents aged 35 years or older in Yuhuan county of Zhejiang Province and explore the associations of overweight and obesity with hypertension.Methods A cross-sectional study was conducted among 124 693 permanent residents aged 35 years or older,who were randomly selected using cluster sampling method from Yuhuan county.Results The prevalence of overweight and obesity was 34.53%and 10.18%among subjects,respectively.The overweight prevalence for male(35.56%)was higher than that for female(33.66%),whereas the obesity prevalence for female(11.26%)was higher than that for male(8.90%)(all P<0.05).The multivariate analysis showed that age,education,occupation,regular physical exercise,smoking,drinking and high-salt diet were possible factors for overweight and obesity(all P<0.05).After adjustment for covariates,compared to participants with normal weight,the multivariate logistic regression indicated that the adjusted odds ratio(OR)and their 95%confidential interval of overweight and obesity were 2.02(95%CI:1.93-2.11)and 3.83(95%CI:3.57-4.10)for hypertension in men,and were 1.94(95%CI:1.86-2.02)and 3.56(95%CI:3.35-3.77)in women,respectively.Conclusions The prevalence of overweight and obesity was high among residents aged 35 years or older in Yuhuan county,and they may relate to the increasing risk of hypertension.
