Nutrition in late preterm infants

Late preterm infants comprise the majority of preterm infants, yet there are few data to support best nutritional practice for these infants. Breastmilk is considered the best choice of enteral feeding for late preterm infants. However, supplementation of breastmilk may be indicated to promote optimal growth. Preterm formulas can be used for supplementation of breastmilk or as a breastmilk substitute but there is little evidence for their use in the late preterm infant. Feeding difficulties are common and some infants require intravenous nutritional support soon after birth. Others require tube feeding until full sucking feeds are established. Future research should focus on whether nutritional support of late preterm babies pending exclusive breastfeeding influences growth, body composition and long-term outcomes of late preterm infants and, if so, how nutritional interventions can optimise these outcomes.
