目的了解成都市社区慢性阻塞性肺疾病(COPD)的发病情况及相关危险因素,为COPD的防治提供依据。方法 2007年8月至2009年8月,随机抽取成都市成华区和郫筒镇各四个社区40岁及以上人群为调查对象。采用整群-随机抽样方法进行调查,使用统一调查表格,并进行肺通气功能检测。结果调查共抽取40岁及以上成年人4315例,其中资料合格、完整且肺功能检查质控合格者3687例,男1539例,女2148例;平均年龄(60.35±13.21)岁。COPD患病率为9.6%,男性患病率高于女性(14.0%比6.4%,P<0.01);COPD患病率随年龄增长而升高,各年龄段患病率差异有统计学意义(P<0.05)。COPD主要的危险因素为吸烟(OR=3.012,95%CI2.390～3.797,P<0.01)和室内油烟污染(OR=2.546,95%CI1.734～3.425,P<0.01)。结论成都市社区COPD患病率明显高于全国平均水平,应该引起高度重视。
Objective To understand the incidence and related risk factors of chronic obstructive pulmonary disease (COPD) in community in Chengdu and provide evidence for the prevention and treatment of COPD. Methods From August 2007 to August 2009, 40 age group and above in each of four communities in Chenghua District and Baituo Town of Chengdu City were randomly selected as the survey subjects. A cluster-random sampling method was used to investigate the use of a unified survey form and pulmonary function tests. Results A total of 4315 adults aged 40 and over were enrolled in this survey. Among them, 3687 were eligible and complete with satisfactory quality control of pulmonary function tests. There were 1539 males and 2148 females, with an average age of 60.35 ± 13.21 years. The prevalence of COPD was 9.6%, and the prevalence rate of males was higher than that of females (14.0% vs 6.4%, P <0.01). The prevalence of COPD increased with age and the prevalence of COPD was statistically significant P <0.05). The main risk factors of COPD were smoking (OR = 3.012, 95% CI2.390 ~ 3.797, P <0.01) and indoor soot pollution (OR = 2.546,95% CI 1.734 ~ 3.425, P <0.01). Conclusion The prevalence of COPD in Chengdu community is significantly higher than the national average, which deserves our attention.
