目前国内关于学校空气污染与儿童呼吸系统健康关系的研究较少。工业的发展和交通的增加可能会影响学校环境中空气污染物的室内暴露。此外，有必要研究环境烟草烟雾（ETS）和中国家庭新建筑材料排放物对呼吸系统的影响。我们研究了中国北方一个燃煤城市的学生哮喘症状与学校室内和室外空气污染以及选定的家庭暴露之间的关系。对太原市城区10所学校11-15岁学生进行问卷调查，收集学生呼吸系统健康状况及家庭环境因素。在冬季，室内和室外的学校空气污染物和气候因素进行了测量。共有1，993名学生（90.2%）参加; 1.8%有累积性哮喘，8.4%有喘息，29.8%有白天呼吸急促发作。二氧化硫、二氧化氮、臭氧和甲醛的室内平均浓度分别为264.8、39.4、10.1和2.3微克/立方米。室外的辐射水平要高出两到三倍。控制可能的混杂因素，无论是喘息或白天或夜间发作的呼吸急促与SO2，NO2，或甲醛呈正相关。此外，ETS和家里的新家具是喘息、白天呼吸困难和呼吸道感染的危险因素。主要来自室外的室内化学空气污染物可能是学生在学校出现呼吸道症状的危险因素，而家中暴露于ETS和新家具的化学排放物可能影响学生的呼吸道健康。
There are few studies on associations between children’s respiratory heath and air pollution in schools in China. The industrial development and increased traffic may affect the indoor exposure to air pollutants in school environment. Moreover, there is a need to study respiratory effects of environmental tobacco smoke (ETS) and emissions from new building materials in homes in China. We studied the associations between pupils’ asthmatic symptoms and indoor and outdoor air pollution in schools, as well as selected home exposures, in a coal-burning city in north China. A questionnaire survey was administered to pupils (11–15 years of age) in 10 schools in urban Taiyuan, collecting data on respiratory health and selected home environmental factors. Indoor and outdoor school air pollutants and climate factors were measured in winter. A total of 1,993 pupils (90.2%) participated; 1.8% had cumulative asthma, 8.4% wheezing, 29.8% had daytime attacks of breathlessness. The indoor average concentrations of sulfur dioxide, nitrogen dioxide, ozone, and formaldehyde by class were 264.8, 39.4, 10.1, and 2.3 μg/m3, respectively. Outdoor levels were two to three times higher. Controlling for possible confounders, either wheeze or daytime or nocturnal attacks of breathlessness were positively associated with SO2, NO2, or formaldehyde. In addition, ETS and new furniture at home were risk factors for wheeze, daytime breathlessness, and respiratory infections. Indoor chemical air pollutants of mainly outdoor origin could be risk factors for pupils’ respiratory symptoms at school, and home exposure to ETS and chemical emissions from new furniture could affect pupils’ respiratory health.
