Study: Counties with more rainfall have higher autism rates

An analysis of data from three states suggests that counties with higher precipitation levels also have higher autism rates, researchers report today.

The scientists speculate that the precipitation itself, which might carry pollutants, or its possible consequences, such as increased TV-watching, decreased vitamin D levels or increased exposure to household chemicals, might trigger autism in genetically susceptible children.

“If you look at the autism literature now, they’re much more open to an environmental trigger,” says lead author Michael Waldman, a Cornell University economist who says his son was diagnosed with an autism spectrum disorder at age 3 but has recovered and is now a normal third-grader.
