Vitamin D Intake in Very Low Birth Weight Infants in Neonatal Intensive Care Unit.

It is unknown how often preterm infants in neonatal intensive care units achieve the American Academy of Pediatrics-recommended daily intake of 400 international units of Vitamin D. We studied 378 preterm infants with birth weight 1500 g or less admitted to our neonatal intensive care unit, 151 infants before and 227 infants after daily vitamin D-intake monitoring was introduced. Infants were stratified into 2 groups: extremely low birth weight (<1000 g) and Very low birth weight (1000-1500 g). Monitoring of daily intake coincided with significant improvement in vitamin D intake in both extremely low birth weight and very low birth weight groups.
