Paternal Obesity Seen as an Independent Risk Factor for Autism

By Joe Elia

A Pediatrics study finds the risk for autism spectrum disorder strongly associated with paternal obesity (that is, with a BMI of 30 or more).

Investigators examined the relationship in a Norwegian cohort of some 93,000 children, whose health was tracked in national databases. By the end of follow-up, at a mean age of 7 years, the odds ratio for autism spectrum disorder among children of obese fathers was 1.53, compared with those of normal-weight fathers. Maternal obesity was not significantly associated.

The authors express surprise at the findings, which suggest an unidentified genetic or epigenetic mechanism.
