目的探讨重庆市永川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永川区3 100名常驻居民（≥18岁）进行调查,调查包括调查问卷填写、体检、血样采集等。结果重庆市永川区成年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先升后降的趋势,在40-〈50岁年龄段达到最高,为50.7%;高血压前期患者的平均年龄吸烟率、饮酒率、体质量指数（BMI）、腰围、总胆固醇、三酰甘油尿酸明显高于血压正常者（P〈0.05）;Logistic回归分析表明,男性、BMI增高、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患病的危险因素（P〈0.05）,而经常体育锻炼则是高血压前期患病的保护因素（P〈0.05）。结论重庆市永川区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。
