Brain dEvelopment and Air polluTion ultrafine particles in scHool childrEn (BREATHE)
The BREATHE study aimed to assess whether exposure of children in primary school to traffic-related air pollutants is associated with impaired cognitive development. The study involved children aged 7 to 10 from 39 schools in Barcelona, Spain, selected based on traffic-related nitrogen dioxide (NO2) values. Schools were paired by socioeconomic vulnerability and type (public/private), with 39 agreeing to participate, reflecting similar socioeconomic vulnerability and NO2 levels as other schools in Barcelona. Families of almost 2,900 children consented to participate, all of whom had been enrolled in their respective schools for at least 6 months before the study. Children were on average 8.5 years old at baseline, and 50% were girls.
