Too little — or too much — of certain substances during pregnancy may increase the odds of having a child with autism. Here we explain what scientists know about these associations.
Autism and other neurodevelopmental conditions are more common among children born by C-section than those delivered vaginally, but the procedure itself does not underlie the association, according to a new study.

About 0.7 percent of children in China aged 6 to 12 — and 1.15 percent of 10- and 11-year-olds in Greece — have autism, figures that are consistent with prevalence estimates elsewhere.
Brothers and sisters of people with autism are both about two to three times more likely than the general population to have an autistic child themselves.
The relative contributions of genetic and environmental factors to autism have held steady over multiple decades, according to a large twin study.
