Autism Linked To Maternal Grandmother’s Smoking During Pregnancy, New Study Says

Study found a link between autism and grandmother's smoking.

A new study has found a link between autism and the smoking habits of the child’s maternal grandmother.

In a study published April 27 in Scientific Reports, scientists at the University of Bristol studied 14,500 participants in its Children of the 90s, which studied kids in the Avon, UK, area born in 1991 to 1992. They found a link between children diagnosed with autism spectrum disorder and their maternal grandmother’s smoking.

“If a girl’s maternal grandmother smoked during pregnancy, the girl is 67 percent more likely to display certain traits linked to autism, such as poor social communication skills and repetitive behaviors”

In addition, the researchers found that the grandmother had a 53 percent chance of having a grandchild afflicted with autism spectrum disorder.
