河南省某地区农村居民肥胖指标与血压及高血压的关系

目的:了解河南省农村居民不同肥胖指标与血压及高血压的关系。方法:2007年7月至2008年7月,采用随机整群抽样的方法抽取河南省某地区68个自然村18岁以上的常住居民共计20152人,进行肥胖和血压水平的横断面调查。结果:随着WHtR和BMI的增加,收缩压、舒张压、脉压和高血压患病率呈升高趋势;中心性肥胖者以上指标高于正常者(P<0.001)。BMI、WC和WHtR与收缩压、舒张压和脉压呈正相关关系(P均<0.001)。相对于BMI<18.5kg.m-2组,18.5kg.m-2～、24.0kg.m-2～和≥28.0kg.m-2组高血压患病的OR分别为1.6(95%CI:1.2～2.0)、2.2(95%CI:1.7～2.9)和3.6(95%CI:2.7～4.8);相对于正常者,中心性肥胖的OR为1.3(95%CI:1.1～1.4);相对于WHtR<0.47组,0.47～、0.52～和≥0.57组的OR分别为1.4(95%CI:1.3～1.6)、1.6(95%CI:1.3～1.8)和2.0(95%CI:1.7～2.4),P均<0.001。结论:河南省某地区农村居民肥胖指标与血压、脉压及高血压患病率之间存在密切联系,应控制全身性肥胖和中心性肥胖,从而防治高血压。

Relationship between obesity indices and blood pressure and hypertension among rural residents in Henan province

Aim:To investigate the relationship between different obesity indices and blood pressure and hypertension among rural residents in Henan province.Methods:Data of 20 152 participants aged ≥18 years in a rural district of Henan in 2007 to 2008 were collected and analyzed.Results:The systolic pressure(SBP),diastolic pressure(DBP),pulse pressure(PP) and the prevalence of hypertension increased along with BMI and WHtR,and the above parameters in people with central obesity were higher than the normal people(P<0.001).All the indices were positively correlated with SBP,DBP and PP(P<0.001).Compared with the BMI<18.5 kg·m-2 group,the odds ratios of 18.5 kg·m-2～,24.0 kg·m-2～,and ≥28.0 kg·m-2 groups for hypertension were 1.6(95%CI:1.2～2.0),2.2(95%CI:1.7～2.9),and 3.6(95%CI:2.7～4.8).Compared with the non-obesity group,the odds ratios of central obesity for hypertension was 1.3(95%CI:1.1～1.4).Compared with the WHtR<0.47 group,the odds ratios of 0.47～,0.52～ and ≥0.57 groups for hypertension were 1.4(95%CI:1.3～1.6),1.6(95%CI:1.3～1.8),and 2.0(95%CI:1.7～2.4),P<0.001.Conclusion:The obesity indices are positively correlated with blood pressure,PP,and the prevalence of hypertension among rural residents in Henan province;general obesity and central obesity should be controlled in order to prevent and treat hypertension.
