Objectives To evaluate vitamin D (vitD) status in early preterm infants (EPTIs) at birth and during birth hospitalisation on current vitD intake. Design/methods Serum 25- hydroxyvitamin-D [25(OH) D] concentrations, vitD intake and risk factors for low vitD status were assessed in 120 infants born at <= 32 weeks gestation. Results Mean (SD) serum 25(OH)D at birth was 46.2 (14.0) nmol/L with lower concentrations in infants born < 28 weeks than at 28-32 weeks gestation, p=0.02. Serum 25(OH) D was < 50 nmol/L in 63% of mothers, 64% of infants at birth and 35% of infants at discharge. Mean daily vitD intake was 289+/-96 IU at 4 weeks of age and 60% achieved 400 IU/day intake at discharge. Conclusions Serum 25(OH) D < 50 nmol/L was widespread in parturient women and in EPTIs at birth and at discharge. Optimising maternal vitD status during pregnancy and improving postnatal vitD intake may enhance infant vitD status during hospitalisation.
