成都地区中年人群高血压前期患病率及影响因素的分析

Prevalence and influential factors of prehypertension among middleaged people in Chengdu area

目的调查成都地区高血压前期患病率及危险因素。方法 2008年我们在成都地区采用分层整群抽样的方法,以社区(村)为单位,共抽取城乡地区40～59岁以上有代表性人口2940人,进行高血压前期及相关因素的调查。结果成都地区中年人群高血压前期患病率41.5%,标准化率为33.7%。40～54岁高血压前期患病率随年龄增大而逐渐增高,55岁开始高血压前期患病率略有降低。男性患病率为47.4%,女性患病率为38.3%,男性患病率高于女性。城市患病率为41.5%,农村患病率为41.3%,城、乡患病率无明显差异。多因素回归分析表明,性别、文化程度、超重或肥胖、腹型肥胖、高胆固醇血症、睡眠时间不足、口味偏咸、体育锻炼频率与高血压前期有关。结论成都地区高血压前期患病率较高,男性、超重或肥胖、腹型肥胖、高胆固醇血症、睡眠时间不足、口味偏咸是高血压前期的主要危险因素,体育锻炼频率及文化程度较高为该人群发生高血压前期的保护因素。在有相关因素的人群中应加强血压监测,及时对高血压前期人群进行干预。
