RESEARCHERS from Simon Fraser University, Canada, in a new study have linked the increased risk of autism spectrum disorder in children to prenatal exposure to air pollution.

As reported by the Cable News Network, the researchers said that pregnant women, who were exposed to the highest level of environmental nitric oxide, an airborne and traffic-related pollutant, were more likely to give birth to autistic children.

The lead author of the study and a member of the Faculty of Health Sciences at the Simon Fraser University, Dr Lief Pagalan, warned that the study, which was published in the medical journal JAMA Pediatrics, only showed an association between prenatal exposure to nitric oxide and autism rates. It did not prove that air pollution caused autism.

“The study adds to the growing concern that there may be no safe levels of exposure to air pollution. Not only did we have access to rich data, enabling us to develop one of the largest studies to date, but we were also able to conduct this study in a city with relatively lower levels of air pollution,” he said.

The researchers analysed the records of 129,436 children born in Vancouver, Canada from 2004 through 2009 and they assessed air pollution exposures in the pregnant woman.

The researchers found out that one per cent of the kids were diagnosed with autism by age five, as they compared autism rates among the children of women who had been exposed to the least amount of air pollution during pregnancy against the rates among the children of women exposed to the most.

According to the study, the odds of developing autism among children prenatally exposed to higher levels of air pollution were 1.04 per cent, the odds of autism in children exposed to higher levels of nitrogen dioxide were 1.06 per cent, and the odds of autism in children exposed to higher levels of nitric oxide were 1.07 per cent. This final increased risk proved to be “statistically significant,” which means that it crossed the line from random chance and shows a true relationship.
