Pregnant? Making sure to take enough Vitamin D, known as the “sunshine vitamin” can help prevent ADHD in your new child.
Alongside genotype, researchers in Finland have found that Vitamin D deficiency during pregnancy can raise the risk of ADHD in the developing baby.
The study is the first population-level research to demonstrate an association between low maternal Vitamin D level in early to mid-pregnancy and an elevated risk for diagnosed attention-deficit/hyperactivity disorder ADHD in the offspring.
The study included 1,067 children born between 1998 and 1999 diagnosed with ADHD in Finland, and the same number of matched controls.
The data was collected before the current national recommendation in Finland for the intake of vitamin D during pregnancy, which is 10 micrograms per day throughout the year.
Vitamin D is essential
The primary investigator, Professor Andre Sourander says that, despite the recommendations, Vitamin D deficiency is still a global problem.
In Finland, for example, mothers’ Vitamin D intake among several immigrant groups is not at a sufficient level.
“This research offers strong evidence that a low level of vitamin D during pregnancy is related to attention deficiency in offspring. As ADHD is one of the most common chronic diseases in children, the research results have a great significance for public health.” says Professor Sourander.
A study in Oregon has also found that supplementing with all known vitamins and essential minerals, at doses between Recommended Daily Allowance and Upper Tolerable Limit, could improve mood and concentration in children with ADHD and emotional dysregulation.
Seeking path to prevention
The study is part of a larger research project that aims to discover the connections between the mother’s health during pregnancy and ADHD in offspring.
The goal is to produce information for developing preventative treatments and measures for identifying children with ADHD risk.
The study was done in collaboration between researchers from the University of Turku, Finland, and Columbia University, New York and it was funded by the National Institute of Mental Health NIHM (USA) and the Academy of Finland, and it is part of the INVEST flagship program of the University of Turku.
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.
