Post-discharge nutrition to optimize preterm infant short- and long-term outcomes.

The preterm infant misses fetal nutrition, and the nutritional deficit is proportional to the degree of preterm birth with very preterm infants demonstrating the greatest need for supplemental nutrition to overcome deficiencies. Preterm infants' growth patterns are linked to both their risk for neurodevelopmental difficulties and to the development of obesity. Therefore, establishing healthy growth patterns by providing the best nutrition both in the hospital and post-hospital discharge is critical for long-term health. Despite numerous clinical trials, uncertainty persists as to the duration of nutritional supplement, the degree of benefit of maternal milk feedings, and the best short-term measures of growth and body composition to predict long-term outcomes. As more is learned about optimal post-discharge nutrition, it is very likely that best practice in post-discharge nutrition will include use of a standardized approach to deliver individualized care.
