中国心力衰竭流行病学调查及其患病率

目的　了解我国成年人慢性心力衰竭 (心衰 )的患病率和分布特征。方法　中国心血管健康多中心合作研究应用四阶段整群随机抽样方法 ,在全国 1 0个省市 (南方和北方各 5个省市 )抽取具有代表性的样本 ,年龄在 35～ 74岁之间 ,城市和农村各半 ,男、女人数均衡。统计不同年龄组、不同性别和不同地区人群的心衰患病率。结果　共抽样调查 35～ 74岁城乡居民 1 5 51 8人 ,心衰患病率为0 9% ;其中男性为 0 7% ,女性为 1 0 % ,女性患病率高于男性 (P <0 0 5)。 35～ 44岁、45～ 54岁、55～64岁、65～ 74岁年龄组的心衰患病率分别为 0 4%、1 0 %、1 3 %和 1 3 % ;随着年龄增高 ,心衰的患病率显著上升 (P <0 0 1 )。我国北方地区心衰患病率为 1 4% ,南方地区心衰患病率为 0 5 % ,北方明显高于南方 (P <0 0 1 ) ;城市人群心衰患病率为 1 1 % ,农村人群心衰患病率为 0 8% ,城市人群心衰患病率高于农村。结论　心衰正在成为我国心血管病领域的重要公共卫生问题

Investigation of prevalence and distributing feature of chronic heart failure in Chinese adult population

Objective To investigate the prevalence and distributing feature of chronic heart failure (CHF) in Chinese adult population Methods Four stage selected random samples aged 35-74 years were used to analyze the prevalence and distributing feature of self reported congestive heart failure in different age, sex and regional groups The sampled adult population were collected from 10 provinces (5 in north and 5 in south) in China The urban and rural population accounted for 50% each, so was the proportion of male to female Results A total of 15 518 adults were surveyed The prevalence of CHF was 0 9%, 0 7% and 1 0% for the general population, the males and females, respectively The females had CHF more frequently than the males ( P <0 05) The prevalence of CHF was 0 4%, 1 0%, 1 3% and 1 3% in 35-44, 45-54, 55-64, 65-74 years of age groups, respectively The prevalence of CHF increased substantially with aging The prevalence of CHF was 1 4% and 0 5% in northern and southern population, respectively; and the prevalence was 1 1% and 0 8% in urban and rural population, respectively The risk of CHF was higher in northern than in southern China and was higher in urban than in rural area Conclusion CHF is becoming an important component of the public health problem of cardiovascular diseases in China
