Study: Shorter Time Between Pregnancies May Increase Autism Risk
According to a study published in Pediatrics, children conceived within one year of a sibling are three times more likely to be diagnosed with autism than those conceived after three years or more.
Although the reason behind the increased risk is unclear, the authors purport two explanations. One, autistic behaviors might be more noticeable when there’s an older sibling close in age for comparison. Second, it may be biological, such a mom lacking essential nutrients like folate, which is important for brain development.
There’s no denying that the numbers have climbed. According to the CDC, in 2006 1 in 110 children had some form of an autism spectrum disorder. However, many experts have disclaimed the recent Pediatrics study, stating that the reasons don’t make sense. Parents usually remember when their child met his/her first milestones, and therefore spacing of births makes no difference. Also, mothers have lacked proper nutrition for decades and the autism has not historically been so prevalent.
