Children exposed to air pollution at school may be at risk of being overweight and obese
Exposure to air pollution, especially at school, may be associated with an increased risk of overweight and obesity during childhood. This is the result of a study carried out by the World Health Institute of Barcelona (ISGlobal), an institution supported by “La Caixa”, carried out with 2,660 children between 7 and 10 years old from 39 schools in Barcelona.
Some studies have linked exposure to air pollution with an increased risk of childhood obesity and weight gain. However, these studies have focused mainly on exposure in the home, regardless of the school environment.
The study, published in the journal Environment International, evaluated the relationship between obesity, overweight and levels of air pollution at school and at home, the two young sections in which children in schools spend the vexgen keto majority weather.
On the one hand, the research team collected data on the weight, height, BMI, obesity and obesity of children. On the other hand, they used sensors in the school yard to measure the levels of outdoor pollution (NO2, carbon carbonate (EC), particulate matter (PM2.5) and nanoparticles) during one week in summer and another in winter. They also estimated exposure levels for NO2, NOx, PM2.5, PM10 and PMcoarse at home.
“We observed that children exposed to high or medium levels of air pollution in the studied particles NO2, PM2.5 and EC had a higher risk of obesity and overweight than those who were exposed to lower levels,” concludes first author Jeroen of Punt. In ISGlobal and IDIAP Jordi Gol. Exposure to high levels of PM10 in the home was also associated with an increased risk of obesity or overweight during childhood, although in this case the analysis was performed with estimates of exposure levels.
