Prenatal Vitamins Limit Risk for Autism

By Heartspring Staff

A previously unreported association has been made between the nutritional status of pregnant mothers, gene variants, and autism. Researchers at UC Davis, in the July 2011 edition of Epidemiology, published standardized clinical assessments on children, aged 24-60 months, to calculate associations between autism, and the vitamin intake of mothers before and during pregnancy.

The study named, CHARGE (CHildhood Autism Risks from Genetics and Environment) enrolled northern California families from 2003 to 2009 explored interaction effects with functional genetic variants carried by the mother, and child.

Mothers with autistic children were compared with mothers who used prenatal vitamins during the first 3 months before pregnancy, or during the first month of pregnancy.

Results confirmed, with a 95% percent confidence ratio, that pre conceptional use of prenatal vitamins reduces the risk of newborns having autism. This wasespecially true for genetically susceptible mothers, and children. With this new approach of investigation, researchers encourage the replication of their work, as well as, calling for more research to identify the mechanistic pathways between autism, and environmental toxic exposures.
