A deficiency of vitamin D in pregnant women lead to an increased risk of autism in their children. At the age of six, these children are two times more likely to have problems with social interaction, and they show different behaviour in comparison with peers.

Conclude that Australian scientists and researchers of the Erasmus MC.

That vitamin D is important for healthy bones is known. But it also seems to be an important role in the development of the brain to play. “Our research provides evidence that a deficiency of vitamin D in pregnant women before the birth of children to the risk of autism increases,” says professor of Psychiatry Henning Tiemeier.

“A too-low vitamin D-mirror of the mother during the pregnancy interferes with optimal development of the brain of these children. At the age of six to exhibit these children are two times more common symptoms that are associated with autism. They make little or no eye contact during social interaction with others. Also they show different behaviour in their movements, the so-called repetitive stereotype behavior.”

Four thousand children

The researchers used the data of more than four thousand children, of which the vitamin D concentrations in the blood of the mothers were measured at twenty weeks of pregnancy and shortly after birth from the umbilical cord.

Tiemeier: “These two moments give us a consistent picture of the situation, because 16 percent of the mothers had low vitamin D-mirror. At birth, one in three children and low vitamin D-mirror, but the low value of the mother during pregnancy appears to be the most important influence on the different symptoms that the children at a later age show.”

In the Netherlands recommends that the Health pregnant women for vitamin D to swallow. Tiemeier: “Our results confirm that this advice is good and that you damage in the development of the brain during pregnancy can prevent, that may not at a later time to recover.”
