Environmental link to autism?

Three new studies identify environmental issues as possible risk factors.

Why does autism happen? Three new studies identify environmental issues as possible risk factors.

A study from the Harvard School of Public Health found that when pregnant women were exposed to high levels of certain air pollutants, such as those from diesel fuel, their risk of having a baby with autism increased by 30 to 50 percent.

A second study, this one from the University of California-Davis, found that women who took iron supplements before getting pregnant or early in pregnancy were 40 percent less likely to have a child with autism.

In a third study, also from UC-Davis, a link was found between a woman’s exposure to household insecticides during pregnancy and her risk of having a child with autism. The Centers for Disease Control and Prevention says at least one in 50 U.S. children will be affected by autism or a related disorder.

Finding out what causes autism is the first big step toward preventing it. For more, go to: http://www.advisory.com/Daily-Briefing/2013/05/06/Three-studies-link-autism-to-environmental-factors
