The Association of Prenatal Vitamin D Sufficiency With Aeroallergen Sensitization and Allergic Rhinitis in Early Childhood.

What Was Tested

This randomized controlled trial looks at Vitamin D, K2, Magnesium and Zinc.

The role of prenatal vitamin D sufficiency and supplementation in the development of childhood aeroallergen sensitization and allergic rhinitis remains uncertain.

Who Took Part

The age groups tagged for this paper are young children and children, women only.

The researchers examined the association between prenatal vitamin D sufficiency status, based on vitamin D levels measured in the first and third trimesters, or vitamin D supplementation treatment assignment with the outcomes of aeroallergen sensitization, parent-reported clinical allergic rhinitis, parent-reported clinical allergic rhinitis with aeroallergen sensitization, food sensitization, any sensitization, eczema, and total IgE at ages 3 and 6 years.

How the Study Was Run

The design is described as randomized.

Random assignment meant chance, not the researchers, decided who got Vitamin D, K2, Magnesium and Zinc and who got the comparison, which limits bias.

The researchers included 414 mother-offspring pairs with offspring aeroallergen sensitization data available at age 6 years in this analysis.
