A study in Pediatrics suggests that pregnancy weight gain does not cause autism spectrum disorders but the two may share underlying processes, such as abnormal hormone levels or inflammation. University of Utah researchers found that pregnancy weight gain patterns were common factors among women who gave birth to children with autism. "We hypothesize that excess pregnancy weight gain serves as a marker of gestational phenomena leading to autism spectrum disorders rather than as a direct risk factor," the authors wrote.
