南京市成年居民体质指数和腰围与高血压关系

目的 探讨江苏省南京市成年居民人体质数(BMI)和腰围(WC)的变化与高血压发病的关系。方法 2004年7月开展南京市3个城区和1个郊县的35岁～居民的慢病相关调查及体格检查,对无高血压的研究对象进行为期3年的随访研究,2007年10月完成项目终期调查。结果 2007年与2004年相比,男、女性的高血压发病率分别为6.0%和5.4%;BMI、WC均值及舒张压均值皆有不同程度的增加;随着基线肥胖程度的增加,高血压的发生风险也增加。与BMI和WC均不超标者相比,超重且伴腹部肥胖者发生高血压的相关性最高(男性:RR=1.74,95%CI=1.19～1.32;女性:RR=2.471,95%CI=1.42～4.03。结论 超重和腹部肥胖是罹患高血压的重要危险因素,BMI、WC的增长与血压升高关系密切,并且BMI和WC的升高均可增加高血压发病的危险。

Body mass index and waist circumferences positively associated with hypertension:a three-year follow-up study in Nanjing

Objective To explore whether the increase of body mass index(BMI)and waistcircum ferences(WC) can predict the higher risk of hypertension in residents of Nanjing.Methods Population based cross sectional study was conducted in local residents older then 35 years in three urban districts and one rural county in July 2004.The subjects with out hypertension in the base line survey were selected to participate the follow-up survey in Oct.2007.Logistic regression models were used to estmiate the relative risk(RR)of developing hyper tension associated with BMI and WC in ba seline and the three year change of BMI and WC.Results The cumulative hypertention incidence of men and women was 6.0% and 5.4%,respectively(χ²=0.32,P>0.05)during the 3 years of follow-up.The risk of developing hypertension rose with the increase of either BMI or WC in ba seline.Compared with the group with neither general obesity(defined by BMI) norabdominal obesity(defined by WC),the group with both general obesity and abdominal obesity had the highe strisk(for male,RR=2.395,95%CI:1.672~3 341,for female,RR=2.550,95%CI=1.809~3.395).Conclusion Over weight and abdominal obesity were miportant independent risk factors of hypertension.The increase of BMI and WC can predict the higher risk of the development of hypertension.
