- Prenatal factors such as vitamin D deficiency during pregnancy, can influence the development of attention deficit hyperactivity disorder (ADHD), say researchers.
- The findings demonstrated an association between low maternal vitamin D level in early to mid-pregnancy and an elevated risk for diagnosed ADHD in the offspring.
- In the study, the researchers used the exceptionally comprehensive Finnish Maternity Cohort (FMC) consisting of approximately 2 million serum specimens collected during the first and early second trimester of pregnancy.
