目的探讨体质指数(BM I)对人群高血压和高血压前期患病率的影响。方法分层抽取社区居民,用描述性流行病学方法进行比较分析。结果根据我国判断BM I的标准超重和肥胖的患病率分别为:男性37.56%、23.00%;女性35.33%、18.69%。按不同BM I标准分组的高血压患病率分别为17.58%(BM I<24.0 kg/m2)、64.52%(BM I:24.0~27.9 kg/m2)、86.30%(BM I≥28.0 kg/m2)。高血压的危险性随着体质指数的增加而升高。多因素Lo-gistic回归分析显示:超重和肥胖是高血压的危险因素。结论超重和肥胖组的高血压患病率明显高于非超重和非肥胖组的患病率,超重和肥胖往往与高血压共存。
Objective To investigate the effect of body mass index (BM I) on the prevalence of hypertension and prehypertension in population. Methods The community residents were drawn by stratification and compared by descriptive epidemiological method. Results The prevalence rates of overweight and obesity in our country according to the standard of BM I were 37.56% for men and 23.00% for men, 35.33% for women and 18.69% for women. The prevalence rates of hypertension according to different BM I criteria were 17.58% (BM I <24.0 kg / m 2), 64.52% (BM I: 24.0-27.9 kg / m 2) and 86.30% (BM I ≧ 28.0 kg / m 2 ). The risk of high blood pressure increases as the body mass index increases. Multi-factor Lo-gistic regression analysis showed that overweight and obesity were risk factors for hypertension. Conclusions The prevalence of hypertension in overweight and obesity groups was significantly higher than that in non-overweight and non-obese groups, and overweight and obesity often coexisted with hypertension.
