Low vitamin D in pregnancy leads to language impairment in children

The study of 743 Caucasian women, conducted by the Telethon Institute for Child Health Research in Perth, measured vitamin D levels at 18 weeks’ gestation and then recorded their children’s behaviour at ages two, five, eight, 10, 14 and 17 years of age.

The researchers found significant linear trends between quartiles of maternal vitamin D levels and language impairment at five and 10 years of age.

Women with vitamin D insufficiency of less than or equal to 46 nmol/L during pregnancy had close to a twofold risk of having a child with clinically significant language difficulties compared to women
