Effect of Vitamin D Supplementation on Recurrent Wheezing in Black Infants Who Were Born Preterm: The D-Wheeze Randomized Clinical Trial.
Summary
The goal of this study is to identify a vitamin D supplementation strategy that best promotes the lung, immune, and overall health of black infants born preterm (28-36 weeks gestational age). This is a high risk population that seems to have unique vitamin D needs, and inappropriate supplementation may promote wheezing or allergy. The results of this study will help form nutritional recommendations for the approximately 100,000 black infants born at 30-36 weeks gestational age in the U.S. every year.
