Low vitamin D in pregnancy could increase eczema risk in baby

Researchers from the University of Western Australia measured 25-hydroxyvitamin D3 in the cord blood of 231 high-risk infants and checked their allergy status at 12 months.

Babies with cord blood 25-hydroxyvitamin D3 < 50nmol/L were more than 2.5 times more likely to develop eczema than those with levels > 75nmol/L. But no associations were found between vitamin D and allergen sensitisation or IgE-mediated food allergy.

“The role of vitamin D in both skin barrier function and local antimicrobial defence could contribute to protective effects at mucosal and cutaneous
