How air pollution affects children at school
Exposure to air pollution, particularly at school, could be associated with a higher risk of overweight and obesity during childhood. This is the conclusion of a study by the Barcelona Institute for Global Health (ISGlobal), an institution supported by “la Caixa,” performed with 2,660 children between 7 and 10 years of age from 39 schools in Barcelona.
A few studies have associated exposure to air pollution with a higher risk of child obesity and overweight. However, these studies focused mainly on exposure at home, without considering the school environment.
The study, published in Environment International and performed under the BREATHE project, assessed for the first time the relation between obesity and overweight risk and air pollution levels at school and home, the two microenvironments where schoolchildren spend most of their time.
