重庆酉阳成年居民高血压前期流行病学特点及危险因素

Epidemiological characteristics and risk factors of prehypertension among adult residents in Youyang area of Chongqing

目的：探讨重庆酉阳地区成年居民高血压前期的流行病学特点及危险因素。方法采取整群随机抽样方法对重庆市酉阳县3100例成年常驻居民进行调查，包括调查问卷填写、体检、血样采集等。结果该地区居民高血压的患病率为43．0％，男性（49．5％）明显高于女性（35．0％），差异有统计学意义（P＜0．05）。高血压前期的患病率随着年龄的增加呈现先升后降的趋势，在＞40～50岁年龄段达到最高（50．7％）。高血压前期患者的吸烟率、饮酒率、体质量指数（BMI）、腰围、总胆固醇、三酰甘油明显明显高于血压正常者（P＜0．05）。Logistic回归分析表明，男性、超重、腹型肥胖、高胆固醇血症、高三酰甘油血症、吸烟、饮酒等是高血压前期的危险因素，而经常体育锻炼则是高血压前期的保护因素。结论重庆酉阳地区成人居民高血压前期的患病率仍较高，应尽早对针上述相关危险因素进行干预。

Objective To investigate the epidemiological characteristics and risk factors of prehypertension a‐mong adult residents in Youyang area of Chongqing .Methods The cluster random sampling method was adopted to conduct the survey on 3 100 ordinarily adult residents ,including the questionnaire filling ,physical examination ,blood sampling ,etc .Results The prevalence rate of prehypertension in Youyang area was 43 .0% ,male was significantly higher than female（49 .5% vs .35 .0% ） ,the difference was statistically significant（P〈 0 .05） .The prevalence rate of prehypertension showed the rising first then decreasing trend with age increase ,and reached the highest（50 .7% ） in the period of 40 - 50 years old .The of moking rate ,drinking rate ,BMI index ,waist circumference ,total cholesterol and triglycerides in the patients with prehypertension were significantly higher than those in the normotensive people （P〈 0 .05） .The Logistic regression analysis indicated that male ,overweight ,abdominal obesity ,hypercholesterol‐emia ,hypertriglyceridemia ,smoking and drinking were the risk factors of prehypertension ,while frequently physical exercise was the protective factor of prehypertension .Conclusion The prevalence rate of prehypertension among the adult residents in Youyang area of Chongqing is higher .The intervention aiming at the related risk factors should be conducted as early as possible .
