摘要
为了探讨室内空气污染与慢性阻塞性肺部疾病(COPD)的关系,对云南省宣威县使用不同生活燃料、年龄≥40岁的农民10892人进行了COPD及其症状的现患率调查,同时测定了调查对象的最大呼气流速(PEF).结果表明,不同燃料造成的室内空气污染对COPD及其症状和最大呼气流速的作用顺序依次为有烟煤>无烟煤>柴.在调整了年龄、性别、吸烟和改灶年限等因素后发现,使用有烟煤和使用无烟煤的人群患COPD的危险性分别是使用柴的4.63倍和1.55倍.改灶年限越长,COPD及其症状的现患率越低,最大呼气流速越高.室内燃煤空气污染是影响宣威慢性阻塞性肺部疾病(COPD)的主要危险因素,改炉改灶对控制COPD及其症状的现患水平,改善肺功能具有积极的作用.
An investigation was conducted on COPD and its present suffer rate of symptom on 10892 farmers of age≥40 years, and using different domestic fuel in Xuanwei County, Yunnan Province, China, for exploring the relation between indoor air pollution and COPD. The expiratory flow rate （PEF） of the investigation object was determined, meanwhile. The proper order of different fuels creating indoor air pollution on COPD and its symptoms and PEF was smoky coal〉smokeless coal〉wood. After adjusting of the factors such as age, sex, smoking and the duration of vented stove usage, it was found that the risk property of using smoky coal and smokeless coal was 4.36 and 1.55 times, respectively, than those using wood. The longer the duration of vented stoves usage, the lower the COPD and its present suffer rate of symptoms. The indoor coal burning pollution was the main risk factor affecting the Xuanwei COPD; the vented stoves usage possessed positive action on controlling COPD and its present suffer rate of symptom level and had better PEF observation values than those who did not.
