A new study from Sweden suggests that maternal exposure to airborne pollution during pregnancy may increase the likelihood of a child being diagnosed with classical autism or an autism spectrum disorder (ASD).<\/p>\n

Erin Flanagan analyzed data on 40,245 births from 2000 to 2009 in Scania, Sweden, linking the mothers\u2019 locations to data on locally emitted PM2.5 (small, inhalable particulate matter) from all sources as well as specifically from wood burning, tailpipe exhaust, and vehicle wear-and-tear. The researchers note that air pollution concentrations in the area they studied generally complied with current European air quality guidelines.<\/p>\n<\/div>

Investigating the association between PM2.5 and either classical autism or the broader category of ASD, they report, \u201cExposure to local PM2.5 during pregnancy from each of the investigated sources was associated with childhood autism in the fully adjusted models. For ASD, similar, but less pronounced, associations were found.\u201d<\/p>\n

The researchers conclude, \u201cThe results add to existing evidence that exposure to air pollution during pregnancy may be associated with an increased risk of childhood autism. Further, these findings suggest that locally produced emissions from both residential wood burning and road traffic related sources (tailpipe exhaust and vehicle wear-and-tear) contribute to this association.\u201d<\/p>\n
