Vitamin D Deficiency Clinical Trial
Preterm newborns are born with lower vitamin D stores. Although vitamin D supplementation is recommended there is no consensus regarding the adequate dose of supplementation for preterm infants.
Vitamin D is a fat-soluble vitamin that is either taken by dietary sources or synthesized
upon exposure to sun light. Although major function is on bone metabolism, in recent years
other effects of Vitamin D attracted attention. Low neonatal vitamin D levels were reported
to be associated with increased risk of respiratory distress syndrome (RDS),
bronchopulmonary dysplasia (BPD) and sepsis.
Vitamin D level in the fetus and the newborn is mostly dependent on maternal vitamin D
levels. Most of the vitamin D is transferred to the fetus during third trimester and as a
result preterm newborns especially those with <32 weeks gestational age are born with lower
vitamin D stores. But there is no consensus regarding the adequate dose of vitamin D
supplementation for preterm infants. The American Academy of Pediatrics recommends
supplementation of 200-400 IU/d vitamin D for preterm infants. And the European Society of
Pediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) recommends 800-1000 IU/d
vitamin D supplementation for preterm infants.
