【摘要】 目的探讨成都城乡地区中老年人群单纯收缩期高血压流行状况及危险因素,为本地区中老年高血压防治工作提供理论依据。方法 2008年应用分层整群抽样方法调查成都城乡地区40~79岁中老年人5205人,经统一培训的30余名医护人员进行血压测量及资料收集。了解中老年单纯收缩期高血压的患病率,分析中老年单纯收缩期高血压的影响因素。结果成都城乡地区中老年人群单纯收缩期高血压患病率为16.64%,标化患病率为15.87%。城市居民患病率为17.18%,农村居民患病率为14.23%;城市高于农村(P<0.01)。男性患病率为16.09%;女性患病率为16.99%(P=0.40)。随着年龄的增加,单纯收缩期高血压患病率呈明显的增高趋势。多元Logistic逐步回归分析发现,年龄、偏咸膳食、腹型肥胖为男性单纯收缩期高血压的危险因素。年龄、绝经、超重或肥胖、腹型肥胖、高胆固醇血症为女性单纯收缩期高血压的危险因素。文化程度高及适度的运动为女性单纯收缩期高血压的保护因素。结论成都地区中老年人单纯收缩期高血压患病率较高,与增龄关系密切。控制腰围、体质量、钠盐摄入,适度运动对中老年人单纯收缩期高血压防治工作有较为重要的意义。更多还原

【Abstract】 Objective To assess the prevalence of isolated systolic hypertension(ISH)and its associated risk factors among the middle-aged and elderly adults in Chengdu area,and further to provide a theoretical basis for the prevention and treatment of hypertension. Methods In 2008,a total of 5205middle-aged and elderly adults aged 40-79 years were enrolled from Chengdu area using a stratified cluster sampling method. Data on blood pressures and other clinical characteristics were collected by more than 30 healthy workers who had undergone unified trainings. The prevalence of ISH was recorded,and potential risk factors were analyzed. Results Overall,the prevalence of ISH was 16.64%in the rural and urban areas of Chengdu,and its standardized prevalence was 15.87%. The prevalence of ISH was 17.18%in the urban areas of Chengdu,which was significantly higher than that(14.23%)in the rural areas(P<0.01). The prevalence of ISH was respectively 16.09% and 16.99% in males and females,the difference being nonsignificant(P=0.40). There was an increasing prevalence with the increase of age. Stepwise Logistic regression analyses indicated that for males age,salty food and abdominal obesity were associated with ISH risk,while for females risk factors included age,menopause,overweight or obesity and abdominal obesity and protective factors included high education degree and appropriate exercise. Conclusion There was a high prevalence of ISH among the middle-aged and elderly adults in Chengdu area,and this prevalence was closely related with aging.It will be of importance to control body waist and weight,reduce salt intake and increase moderate exercise to prevent ISH in this area.更多还原
