室内空气污染对呼吸道症状和肺功能的影响

Effects of indoor air pollution on respiratory symptoms and lung function

目的 探讨室内空气污染对呼吸道症状和肺功能的影响。方法 通过逐步回归分析方法分析不同生活燃料造成的室内空气污染对肺功能的影响。结果 分析了 1 0 892人的调查资料 ,在调整了混杂因素影响后 ,家庭内使用有烟煤的人群产生呼吸道症状 (气短、咳嗽和咳痰 )的危险性高于使用无烟煤者。使用有烟煤者患有气短、咳嗽和咳痰的 OR值分别为 1 .71、3.30和 4 .2 3;使用无烟煤者发生咳嗽、咳痰的危险性分别是使用柴者的 1 .35和 1 .6 7倍。改炉灶可以降低这些症状的出现率。结论 使用有烟煤造成的室内空气污染是最大呼气流速 (PEER)降低的主要危险因素 。

Objective To study effects of indoor air pollution on respiratory symptoms and lung function. Methods To analyze the lung effects of indoor air pollution by using diverse living fuel with the stepwise regression analysis. Results With analysis of 10 892 people's data, after adjusted the confounding factors, people who using smoking coal as cooking fuel had a greater risk of respiratory symptoms including breathless, cough and sputum than who using smokeless coal, OR were 1.71, 3.30,4.23, respectively. The risk of cough and sputum that compared people who using smokeless coal with who using wood as cooking fuel was 1.35 and 1.67 times higher, repectively. Improved stove type could decrease the risk of the respiratory symptoms and improve lung function. Conclusions Indoor air pollution caused by smoking coal is the main risk factor of peak expiratory flow rate (PEER), and the next is smokeless coal and wood in turn.
