BACKGROUND The associations between indoor environmental quality (IEQ) in homes and symptom reporting of children have been extensively studied, but only few large-scale studies have been done in schools. We examined associations between expert-assessed IEQ in schools and pupils' reporting of different symptoms, and whether associations were stronger if participants relate symptoms to the school environment. METHODS The questionnaire survey was done in all primary and secondary schools in two areas of Helsinki, Finland. Primary school pupils (grade 3-6, n = 8775, 99 school-buildings) and secondary school pupils (grade 7-9, n = 3410, 30 school-buildings) reported their symptoms. Symptoms were combined into respiratory, lower respiratory, eye, skin, and general symptom groups. Surveys were also done among the parents of the primary school pupils (grade 1-6, n = 3540, 88 school buildings), but results are reported only in the supplement due to the low response rate (20% in 2017 and 13% in 2018). The associations between IEQ and symptoms were analyzed using multilevel logistic regression analysis. RESULTS Several of the IEQ indicators were highly correlated and indicators were therefore mainly analyzed by combining them into a summary score and into latent classes. Dose-response associations were found between IEQ problems and higher reporting of respiratory and general symptoms among both primary and secondary school pupils. Some associations were also observed with lower respiratory and skin symptoms, but not with eye symptoms. The associations were somewhat stronger with symptoms related to the school environment compared to symptoms reported without such relation: for a unit change in IEQ summary score and respiratory symptoms in primary schools, odds ratios were 1.07 (95% CI 1.02-1.06) and 1.04 (95% CI 1.04-1.10), and in secondary schools 1.09 (95% CI 1.01-1.09) and 1.05 (95% CI 1.02-1.17), respectively. CONCLUSIONS Expert-assessed IEQ problems in schools were associated with increased reporting of especially respiratory and general symptoms. The associations were only somewhat stronger in magnitude for symptoms reported in relation to the school environment compared to symptoms reported without such relation.

学校室内环境质量与学生管理问卷中症状报告之间的关联。

背景技术已经广泛研究了家庭中的室内环境质量（IEQ）与儿童的症状报告之间的关联，但是在学校中仅进行了很少的大规模研究。我们研究了学校专家评估的IEQ与学生报告不同症状之间的关联，以及如果参与者将症状与学校环境相关联，则该关联是否更强。方法在芬兰赫尔辛基两个地区的所有中小学进行了问卷调查。小学生（3-6年级，n = 8775，99个教学楼）和中学生（7-9年级，n = 3410，30个教学楼）报告了他们的症状。症状分为呼吸，下呼吸，眼，皮肤和一般症状组。还对小学生的父母进行了调查（1-6年级，n = 3540，有88栋教学楼），但由于响应率低（2017年为20％，2017年为13％），仅在补品中报告了结果。 2018）。IEQ和症状之间的关联使用多级Logistic回归分析进行了分析。结果IEQ指标中的几个指标高度相关，因此主要通过将指标合并为总分和潜伏类来对指标进行分析。在小学生和中学生的IEQ问题与更高的呼吸道症状和一般症状报告之间发现了剂量反应关系。还观察到与下呼吸道和皮肤症状有关，但与眼睛症状无关。与无此关联的症状相比，与学校环境相关的症状的关联性更强：对于IEQ汇总得分和小学呼吸症状的单位变化，优势比分别为1.07（95％CI 1.02-1.06）和1.04（ 95％CI 1.04-1.10）和中学1.09（95％CI 1.01-1.09）和1.05（95％CI 1.02-1.17）。结论在学校中，专家评估的IEQ问题与特别是呼吸道症状和一般症状的报告增多有关。与所报告的与学校环境有关的症状相比，与学校环境有关的症状在关联上的强度稍强。07（95％CI 1.02-1.06）和1.04（95％CI 1.04-1.10），中学1.09（95％CI 1.01-1.09）和1.05（95％CI 1.02-1.17）。结论在学校，专家评估的IEQ问题与特别是呼吸道症状和一般症状的报告增多有关。与所报告的与学校环境有关的症状相比，与学校环境有关的症状在关联上的强度稍强。07（95％CI 1.02-1.06）和1.04（95％CI 1.04-1.10），中学1.09（95％CI 1.01-1.09）和1.05（95％CI 1.02-1.17）。结论在学校中，专家评估的IEQ问题与特别是呼吸道症状和一般症状的报告增多有关。与所报告的与学校环境有关的症状相比，与学校环境有关的症状在关联上的强度稍强。
