Scientists from the University of Queensland have concluded that a lack of vitamin D during pregnancy can lead to the birth of a child with autism.
Previously, the question of why boys are three times more likely to develop autism spectrum disorders than girls has remained open. It was assumed that this is due to the influence of high testosterone levels in the prenatal period. It was later found that a lack of vitamin D in the 20th week of pregnancy was associated with an increased likelihood of autism spectrum disorders in children.
Scientists at the University of Queensland, in turn, conducted a study aimed at elucidating the effect of vitamin D deficiency on the occurrence of autistic disorder. As a result, it was found that a lack of vitamin D leads to an increase in testosterone in the fetus's brain and increases the likelihood of autism in the child. Moreover, the connection between these states is inherent only in boys.
