Fine particulate
air pollution linked with increased autism risk

Public Health

Summary:

Women exposed to high
levels of fine particulate matter specifically during pregnancy -- particularly
during the third trimester -- may face up to twice the risk of having a child
with autism than mothers living in areas with low particulate matter, according
to a study. The greater the exposure, the greater the risk, researchers found.
It was the first US-wide study exploring the link between airborne particulate
matter and autism.

women exposed to high
levels of fine particulate matter specifically during pregnancy--particularly
during the third trimester--may face up to twice the risk of having a child
with autism than mothers living in areas with low particulate matter, according
to a new study from Harvard School of Public Health (HSPH). The greater the
exposure, the greater the risk, researchers found. It was the first U.S.-wide
study exploring the link between airborne particulate matter and autism.

"Our data add additional important support to the hypothesis that
maternal exposure to air pollution contributes to the risk of autism spectrum
disorders," said Marc Weisskopf, associate professor of environmental and
occupational epidemiology and senior author of the study. "The specificity
of our findings for the pregnancy period, and third trimester in particular,
rules out many other possible explanations for these findings."

The study appears online December 18, 2014 inEnvironmental Health
Perspectives.

Prior studies have suggested that, in addition to genetics, exposure to
airborne environmental contaminants, particularly during pregnancy and early
life, may affect risk of autism. This study focused specifically on the
pregnancy period.

The study population included offspring of participants living in all 50
states in Nurses' Health Study II, a cohort of more than 116,000 female U.S.
nurses begun in 1989. The researchers collected data on where participants
lived during their pregnancies as well as data from the U.S. Environmental
Protection Agency and other sources on levels of fine particulate matter air
pollution (PM2.5)--particles 2.5 microns in diameter or smaller--in locations
across the U.S. The researchers identified 245 children who were diagnosed with
autism spectrum disorder (ASD) and a control group of 1,522 children without
ASD during the time period studied.

The researchers explored the association between autism and exposure to
PM2.5 before, during, and after pregnancy. They also calculated exposure to
PM2.5 during each pregnancy trimester.

Exposure to PM2.5 was significantly associated with autism during
pregnancy, but not before or after, the study found. And during the pregnancy,
the third trimester specifically was significantly associated with an increased
risk. Little association was found between air pollution from larger-sized
particles (PM10-2.5) and autism.

"The evidence base for a role for maternal exposure to air pollution
increasing the risk of autism spectrum disorders is becoming quite
strong," said Weisskopf. "This not only gives us important insight as
we continue to pursue the origins of autism spectrum disorders, but as a
modifiable exposure, opens the door to thinking about possible preventative
measures."
