Fewer indications of ADHD in children whose mothers took vitamin D during pregnancy

Children of mothers who took vitamin D during pregnancy with resultant high levels of the vitamin in the umbilical blood have fewer symptoms of ADHD at the age of 2½ years.

These were the findings in a new study from the Odense Child Cohort just published in The Australia & New Zealand Journal of Psychiatry.

“And for every 10 nmol/L increase in the vitamin D concentration in umbilical blood, the risk of a being among the 10% highest score on the ADHD symptom scale fell by 11%,” explains one of the study’s initiators, Professor Niels Bilenberg.

1,233 children from Odense Municipality were monitored in the study. Vitamin D was measured in umbilical blood, and mothers completed the Child Behavior Checklist (CBCL) when their child was 2½ years old. The CBCL questionnaire can be used to identify early symptoms of ADHD, even though an ADHD diagnosis cannot be made at that age.
