佛山市南海区社区人群体型指数、腰围与高血压的关系

目的采用腰围(WC)、体质指数(BMI)综合评价广东省佛山市南海区成年人中心性肥胖者高血压患病风险。方法采用多阶段分层随机抽样方法抽取南海区2个街道6个镇共17124户中18岁以上常住居民进行调查。采用入户面对面访谈的方法,并进行相关人体测量。采用SPSS13.0统计软件进行多因素Logistic回归分析,比较各BMI组别中心性肥胖者高血压患病的OR值。结果体质指数偏瘦、正常、超重和肥胖组中,男性中心性肥胖者高血压患病率分别为14.6%、23.8%、34.1%和42.7%;女性中心性肥胖者高血压患病率分别为20.3%,24.2%,33.8%和43.5%;除男性体型偏瘦组外,中心性肥胖者高血压患病率均明显高于同组内的正常腰围人群(P0.01);调整混杂因素(年龄、吸烟、饮酒和体育锻炼等)后,与正常腰围人群比较,BMI正常、超重及肥胖组别中男性中心性肥胖者患高血压患病的OR值分别为1.485(1.319~1.672)、1.827(1.536~2.191)、2.849(1.659~4.893);中心性肥胖女性BMI偏瘦、正常、超重及肥胖组高血压患病OR值分别为1.642(1.112~2.425)、1.530(1.363~1.717)、1.644(1.299~2.080)、3.529(2.001~6.225)。结论 BMI与WC两者结合可明显提高高血压风险预测价值;应将腹型肥胖尤其是全身性肥胖合并腹型肥胖的人群作为社区高血压防治的重点干预人群。

Relationship between body mass index,waist circumstance and hypertension among community residents in Nanhai District,Foshan City

Objective To comprehensively evaluate the risk for the occurrence of hypertension among adults with central obe-sity in Nanhai District,Foshan City,Guangdong Province by waist circumstance （WC） and body mass index （BMI）.MethodsMultistage stratified random sampling method was used to select permanent residents aged 18 years and above from 17,124families in 2 streets and 6 towns of Nanhai District.The data of these residents were collected with questionnaires by face-to-face interview.Physical examinations and blood pressure determination were taken by trained interviewers.Multi-factor Logis-tic regression analysis was conducted by SPSS13.0 statistical software.Odds ratio for hypertension associated with central obesitywas compared among the 4 BMI groups.Results The prevalence rates of hypertension in the male subjects with central obe-sity of the lean,normal-weight,over-weight and obesity BMI groups were 14.6 ％,23.8 ％,34.1％ and 42.7 ％ respective-ly,and those in the female subjects with central obesity of the above-mentioned groups were 20.3％,24.2％,33.8％ and43.5 ％ respectively.Except for the male subjects of the lean BMI group,the prevalence rates of hypertension in the subjects withcentral obesity of the other 3 groups were significantly higher than those in the subjects with normal WC of the same BMI groups（P ＜ 0.01）.After adjusting the confounding factors （age,smoking,alcohol consumption,physical exercise and so on）,odds ra-tios for hypertension in the male subjects with central obesity of the normal-weight,over weight and obesity BMI groups were1.485 （1.319～ 1.672）,1.827 （1.536 ～ 2.191） and 2.849 （1.659 ～ 4.893） respectively when compared with the subjects withnormal WC of the sarne BMI groups.Odds ratios for hypertension in the female subjects with central obesity of the lean,normal-weight,over-weight and obesity BMI groups were 1.642 （1.112～ 2.425）,1.530 （1.363～ 1.717）,1.644 （1.299～ 2.080）and 3.529（2.001～6.225） respectively.Conelusion
