Vitamin D lack in mothers associated with ADHD in children

22 May 2020

Low levels of maternal vitamin D in early pregnancy are associated with an increased risk of attention deficit hyperactivity disorder (ADHD) in children, according to a study.

Researchers observed a significant association between decreasing maternal vitamin D levels and offspring ADHD: an odds ratio of 1.45 when adjusted for maternal socioeconomic status and age. ADHD risk was higher for the lowest versus highest quintile of maternal vitamin D levels, with an adjusted odds ratio of 1.53. The study, published in the Journal of the American Academy of Child and Adolescent Psychiatry, analysed 1067 cases of ADHD between 1998 and 1999, and 1067 matched controls.

The study’s authors said if these findings are replicated, they might have public health implications for vitamin D supplementation and perhaps changing lifestyle behaviours during pregnancy to ensure optimal maternal vitamin D levels.
