目的:探讨室内环境因素与学龄儿童呼吸系统健康之间的关联性。方法:调查对象为广州市3个不同空气污染程度地区8所小学的2179例3、4年级小学生。通过标准化问卷了解调查儿童的家庭、社会经济状况和呼吸道症状、疾病史,并测量其身高、体质量和肺功能。结果:在室内环境诸多因素中,地毯、新家具、装修、熏香、发霉、宠物和被动吸烟均显著增加儿童呼吸道症状和疾病的患病风险,OR值1.34～2.88。室内熏香和房间夏季通风多与儿童肺功能水平呈负相关(P<0.05)。结论:室内环境中存在多种因素显著影响学龄儿童呼吸系统健康。
Objective: To explore the relationship between indoor environmental factors and respiratory health in school-age children. Methods: The survey was conducted on 2179 Grade 3 and 4 pupils in 8 primary schools in 3 districts with different levels of air pollution in Guangzhou. Investigate children’s family, socioeconomic status and respiratory symptoms, disease history, and measure their height, weight, and lung function through standardized questionnaires. Results: Carpet, new furniture, decoration, incense, mildew, pet and passive smoking all significantly increased the risk of respiratory symptoms and diseases in children. The OR values ranged from 1.34 to 2.88. Room incense and summer ventilation in the room and child lung function level was negatively correlated (P <0.05). Conclusion: There are many factors in the indoor environment that significantly affect the respiratory health of school-age children.
