摘要
目的探讨煤烟型大气污染对中小学生呼吸系统健康的影响,为大气污染的预防控制提供依据。方法采用分层整群抽样的方法,抽取淮南市燃煤污染区3所中学和5所小学的1892名学生进行呼吸道症状与呼吸系统疾病现况调查,以同城农村的2所中学及2所小学的917名学生为对照。结果城区学生呼吸系统总症状、咳嗽、咳痰、咽痛、气喘等呼吸道症状,感冒、鼻炎、咽炎、扁桃体炎、急性支气管炎等呼吸系统疾病的检出率均显著高于农村学生(P<0.01或P<0.05);呼吸系其他症状与疾病差异均无统计学意义(P值均>0.05)。结论煤烟型大气污染可引起中小学生呼吸系统症状和疾病的检出率增高,是导致儿童呼吸系统损害的危险因素。
Objective To investigate impact of coal-burning air pollution on respiratory system among primary and middle school students, and to provide evidence for the prevention and control of air pollution. Methods A stratified cluster sampling was taken to investigate the respiratory diseases of 1 892 students in three middle schools and five primary schools in the coal-fired contaminated area compared with the 917 students in two middle schools and two primary schools in rural areas in Huainan, Anhui province. Results The prevalence rate of urban students was significantly higher than students in rural areas in aspects of respiratory symptoms and respiratory diseases such as cough, expectoration, pharyngalgia, asthma, common cold, rhintis, pharyngitis, tonsillitis, acute bronchitis and so on. However, other respiratory symptoms and disease had no significant difference. Conclusion Coal-burning air pollution may cause respiratory diseases in primary and middle school students and increase the prevalence rate of respiratory symptoms, which is the health risk factor to cause damage to children＇s respiratory system.
