Association between vitamin D status in early pregnancy and atopy in offspring in a vitamin D deplete cohort

Vitamin D status may play a role in the development of atopic diseases due to its action on lung development and immune system development and function. Our objective was to assess whether 25-hydroxyvitamin D (25OHD) levels in maternal blood in pregnancy were associated with atopy in children. We analysed 279 mother-child pairs from the ROLO study conducted in Dublin, Ireland. Serum 25OHD was measured at 13 and 28 weeks of pregnancy. Development...
