Vitamin D Deficiency during Pregnancy Connected to Elevated Risk of ADHD
According to a study conducted in Finland, the risk of ADHD was 34 percent higher in children whose mother had a vitamin D deficiency during pregnancy than in those children whose mother’s vitamin D level was sufficient during the first and second trimesters. The result was adjusted for maternal age, socioeconomic status and psychiatric history. The study was done in collaboration between researchers from the University of Turku, Finland, and Columbia University, New York.
