Prenatal vitamin D status and a mother’s race affected their children’s allergy and some pulmonology outcomes, according to two studies presented at the annual meeting of the American Academy of Allergy, Asthma & Immunology in Orlando.
Researchers in the first study looked at the link between prenatal vitamin D levels and allergic rhinitis in children of 1,091 women-child dyads participating in the Conditions Affecting Neurocognitive Development in Early Childhood (CANDLE) cohort in Tennessee.
Maternal vitamin status was ascertained in the second trimester and the children’s allergic rhinitis status was determined while they were between 4 and 6 years of age. Results were analyzed utilizing covariates such as the season of the child’s birth, sex, education and whether the mother had asthma.
Sixty-seven percent of the women studied were black and 23% of the children had allergic rhinitis. The median vitamin D levels were 25.1 ng/mL in the white women and 19.2 ng/mL in the black women.
