Studies suggest that children exposed to air pollution are at increased risk of developing ADHD.health

ADHD is one of the most common neurodevelopmental disorders in children. Children living in areas with high air pollution and low levels of green space may have an increased risk of developing ADHD by up to 62%, according to a new study led by researchers at the Barcelona Global Health Institute (ISGlobal). ..

This study was published in the journal “Environment International”.

We have found that children living in areas with high levels of air pollution from PM 2.5 particles and very low levels of green space can have an increased risk of developing ADHD by up to 62%. On the other hand, children living in more environmentally friendly and less polluted areas have a 50% lower risk of developing disability.

The purpose of this scientific study is childhood exposure to greenery, air pollution, noise and the development of ADHD, one of the most common neurodevelopmental disorders affecting up to about 5-10% of children. It was to investigate the possibility of a relationship with the rate. And youth. One of the goals of this study was to assess the potential effects of these exposures on joints in relation to ADHD.

This study used birth management data from 2000 to 2001 in Metro Vancouver to obtain data on ADHD cases from hospital records, doctor visits, and prescriptions. The proportion of green space in the vicinity of the participants was estimated using novel and accurate satellite metrics, and the habitat levels and noise levels of the two air pollutants (NO2 and PM 2.5) provided an available exposure model. Estimated using. Finally, the possible association between the three environmental exposures and ADHD was assessed using a statistical model that allowed the hazard ratio to be determined.

Researchers have identified 1,217 cases of ADHD. This represents 4.2 percent of the total study population. Green space analysis revealed that participants living in areas with high vegetation rates were at lower risk of ADHD. More specifically, the results show that a 12% increase in vegetation percentage reduces the risk of ADHD by 10%.

Regarding air pollution, the opposite association was observed in PM2.5. Participants with high exposure to detailed articles were at increased risk of ADHD (for every 2.1 ug increase in PM2.5 levels, the risk of ADHD increases by 11%).

No association was found for the remaining environmental exposures evaluated (NO2 and noise).

The results were consistent with previous studies that discovered the respective associations of green space and air pollution with ADHD. However, most of the studies conducted so far have focused on assessing a single exposure and rarely assessed the combined effects of multiple environmental exposures.

“We have found that children living in green areas with less air pollution have a significantly reduced risk of ADHD. This is environmental inequality, and children living in highly polluted and less green areas We face a disproportionate amount of risk. ” Lead author Matilda van den Bosch.

“These associations are especially important because exposures occur in early childhood, when children are particularly important for the development of vulnerable brains. Importantly, these exposures are variable and healthier. The findings need to be taken into account for a typical city plan, “she added. ..

“Our findings show that the link between PM 2.5 and ADHD is weakened by residential green spaces and vice versa,” said Weeiran Yuchi, a university researcher in British Columbia (Canada). ) And the lead author of the study.
