背景：室内空气质量差被认为与西方世界哮喘患病率的增加有关，特别是在儿童和年轻人中。除了家，学校是孩子们最重要的室内环境。目的研究当前中学生哮喘患病率及其与学校环境、个人因素和家庭暴露的关系。方法随机抽取瑞典乌普萨拉县11所学校的762名七年级学生（13-14岁）进行问卷调查，收集哮喘症状、其他健康方面和家庭暴露情况等数据。回答“是”的学生被医生诊断患有哮喘，最近有哮喘发作，或使用哮喘药物被定义为目前患有哮喘。通过对28个教室进行测量，收集了学校接触情况的数据。采用多元logistic回归分析哮喘与暴露的关系。结果627人（82%）完成问卷调查。有40名小学生（6.4%）患有哮喘。目前的哮喘在那些有特应性倾向、食物过敏或在日托中心待了几年的人身上更为常见。控制这些因素后，当前哮喘与学校环境中的几个因素有关。在那些更大的学校里，有更多的开放式架子，更低的室温，更高的相对空气湿度，更高浓度的甲醛或其他挥发性有机化合物，可存活的霉菌或细菌，或更多的猫过敏原。结论虽然小学生上学的时间只占其全部时间的一小部分，但我们的研究表明，学校环境的质量是重要的，并可能影响哮喘症状。
Background Poor indoor air quality has been suggested to be related to the increase in the prevalence of asthma that has occurred in the western world, especially among children and young persons. Apart from the home, school is the most important indoor environment for children.Objectives The aims were to study the prevalence of current asthma among secondary pupils and its relationship to the school environment, but also to personal factors and domestic exposures.Methods Data on asthmatic symptoms, other health aspects, and domestic exposures were gathered using a questionnaire which was sent to 762 pupils in the seventh form (13-14 years old) in 11 randomly chosen schools in the county of Uppsala in Sweden. Pupils answering 'yes' to having had asthma diagnosed by a physician, and having had recent asthma attacks, or who used asthma medication were defined as having current asthma. Data on exposures at school were gathered by measurements in 28 classrooms. The relationship between asthma and exposures was analysed by multiple logistic regression.Results The questionnaire was completed by 627 (82%). Current asthma was found among 40 pupils (6.4%). Current asthma was more common in those who had an atopic disposition, or food allergy, or who had attended a day care centre for several years. Controlling for these factors, current asthma was related to several factors in the school environment. There were more pupils with current asthma in schools that were larger, had more open shelves, lower room temperature, higher relative air humidity, higher concentrations of formaldehyde or other volatile organic compounds, viable moulds or bacteria or more cat allergen in the settled dust.Conclusions Although the pupils attended school for a minor part of their time, our study indicates that the quality of the school environment is of importance and may affect asthmatic symptoms.
