An increased vitamin D value in mothers seems to have a positive effect on the child
Researchers have now found that pregnant women can significantly reduce their children's hyperactivity risk. They just need more vitamin D for this. We get this so-called sunshine vitamin, for example, from sunbathing, oily fish, egg yolk and, of course, from vitamin D supplements.
Researchers at the University of Southern Denmark found that vitamin D protects the unborn child of pregnant women from the risk of hyperactivity. So expectant mothers should spend more time in the sun or adjust their diet. The doctors published the results of their study in the journal "Australia & New Zealand Journal of Psychatry".
Study checks the value of vitamin D in umbilical cords
In a Danish study, the concentrations of vitamin D in the umbilical cords of mothers were measured. In addition, the mothers had to fill out a questionnaire that described the behavior of the child at the age of two and a half, the researchers explain.
Children of mothers with higher vitamin D levels are at lower risk for ADHD
The study found that children of mothers with a higher level of vitamin D were less likely to develop ADHD during pregnancy.
If the vitamin D level in the umbilical cord blood is high enough, this protects the children
There was a clear trend when mothers took more vitamin D and the vitamin D level in their umbilical cord blood was above 25 nmol / l, their children were less likely to develop ADHD, says Prof. Niels Bilenberg from the University of Southern Denmark.
Smoking, alcohol consumption and obesity also increase the risk of ADHD
Other factors could also be linked to the development of ADHD. These include, for example, mother's age, smoking, alcohol consumption and obesity. A possible link between taking vitamin D and early symptoms of ADHD has never been investigated in detail before, explains Prof. Bilenberg.
Follow-up examination could bring interesting results
"We were extremely surprised to find such a clear connection at an early age," said co-authors Jens Bull Aaby and Mats Mossin from the University of Southern Denmark. It is impossible to tell exactly which of the children will develop ADHD later in life. A further follow-up examination of these children could therefore bring extremely interesting results.
Further research could clarify the causes
Previous studies have already shown that vitamin D plays an important role in the early development of the brain, the experts explain. We cannot say with certainty that vitamin D protects against the early symptoms of ADHD. The current study shows only a connection between the intake of vitamin D and the development of ADHD. To explain this, we need to do more research, adds Aaby. (as)
