Children born to obese fathers, but not obese mothers, may have a slightly higher risk of autism than kids with thinner dads, a large new study suggests.
Researchers found that of nearly 93,000 Norwegian children they followed, those born to obese dads had double the risk of developing autism. But the odds were still small: just under 0.3 percent were diagnosed with autism, versus 0.14 percent of kids with normal-weight fathers.
