Black preterm infants who received vitamin D supplementation until 12 months’ adjusted gestational age were nearly 11% less likely to experience recurrent wheezing when compared with neonates who did not receive the supplementation, according to research published in JAMA.

“Parents need to know that African American preterm infants are at high risk of wheezing in infancy,” Anna Maria Hibbs, MD, MSCE, FAAP, from Case Western Reserve University and the University Hospitals Cleveland Medical Center, said in a press release. “I hope this study can highlight the burden of wheezing illness experienced by premature babies and the importance of targeting interventions that can lessen this burden.”
