Vitamin D status and the adequacy of its supplementation during the first year of life in preterm infants in northern Japan
Preterm infants in northern Japan exhibited substantial VDD, regardless of gestational age. In our cohort, VD supplementation at 400 IU/day safely increased 25OHD levels. However, VD levels improved gradually over the months, and several of these infants developed secondary hyperparathyroidism. Further studies are warranted to determine the optimal VD supplementation dose for preterm infants in this region.
