煤烟型大气污染对成人呼吸系统疾病及其症状影响的研究

Effects of air pollution from burning coal on respiratory diseases in adults

采用环境流行病学方法调查了太原市 3个不同程度大气污染研究区成人的呼吸系统疾病和症状以及相关影响因素。结果表明 ,成人呼吸系统症状的标化发生率和疫区的标化患病率均为重度污染区 >中度污染区 >相对清洁区 (P <0 0 5 ) ,出现呼吸系统症状和疾病的危险性 ,重、中污染区分别是相对清洁区的1 8倍和 2 1倍、1 3倍和 1 8倍 ,经多因素Logistic回归分析 ,在调整了年龄、性别、职业、吸烟、家庭燃料、家族史等因素后 ,燃煤产生的LNSO2 、LNTSP、LNPM1 0 、LNPM2 5 每增加一个单位 ,成人呼吸系统症状发生的危险性分别增加 1 39倍、1 71倍、1 6 7倍和 1 79倍 ,慢性阻塞性肺部疾病患病的危险性分别增加 1 31倍、1 5 3倍、1 5 1倍和 1 6 8倍。提示煤烟型大气污染对成人呼吸系统症状和疾病的发生已产生一定程度的影响。
