This study found no evidence of a significant
association between IAP in nursery and primary schools and the prevalence of childhood asthma. However, reported
active wheezing was associated with higher NO2, and reduced FEV1 was associated with higher O3 and PM2.5, despite NO2 and O3 in schools were always below the 200 μgm−3 threshold from WHO and National legislation,
respectively. Moreover, sensitised children to common aeroallergens were more likely to have asthma during childhood when exposed to particulate matter in schools. These findings support the urgent need for mitigation measures to reduce IAP in schools, reducing its burden to children's health.
