Are vitamin supplements used before or during pregnancy associated with a reduction in the risk of autism? A recent study suggests this while pointing out certain interferences.
The use of folic acid supplements and multivitamins by women before and during pregnancy is associated with a lower probability of autism spectrum disorder in children, but this conclusion should be interpreted with caution as other intercurrent factors can explain it. This is apparent from a study published in JAMA Psychiatry.
A vitamin deficiency during pregnancy is associated in some studies with deficits in neuronal development in children. To prevent neural tube defects in children, it is recommended that pregnant women take folic acid during pregnancy, but the results of the studies on this combination are contradictory.
A risk reduction that remains probable
To unravel the true and false, 45,300 Israeli children born between 2003-2007 were examined. At the end of the analyzes, the association between the use of maternal supplements and the likelihood of autism in children was reported as a statistical measure known as relative risk (a relative risk less than 1 suggests a lower risk).
The mother's intake of folic acid and multivitamin supplements before and during pregnancy appears to be associated with a reduction in this risk in children compared to the children of mothers who do not ingest it.
However, the authors can not exclude that the risk reduction is due to other associated causes. Further complementary research is therefore essential.
