Vitamin D deficiency during pregnancy linked to autism

Queensland researchers who analysed the blood of pregnant women and their offspring found those with vitamin D deficiencies scored “significantly higher” on the autism scale than those whose vitamin D levels were regular.

The Queensland Brain Institute study found that pregnant women with low vitamin D levels at 20 weeks’ gestation were more likely to have a child with autistic traits by the age of six.

"This study provides further evidence that low vitamin D is associated with neurodevelopmental disorders," says Professor John McGrath from the University of Queensland. "Just as taking folate in pregnancy has reduced the incidence of spina bifida, the result of this study suggests that prenatal Vitamin D supplements may reduce the incidence of autism."
