Core Outcome Measures in Effectiveness Trials

Core Outcome Set for NEOnatal Nutrition and growth studies (COSNEON).

General Information

Newborns make a transition from intra-uterine feeding through placental supplies to feeding through their gastrointestinal system. Newborns who were born with complications such as too small or too early may benefit from individualized composition of the various components. International consensus is that increased energy and protein intakes in the neonatal period of preterm babies improve growth and neurodevelopment, but after more than 100 y of research the optimum intakes of energy and protein remain unknown. We suggest an important factor contributing to the lack of progress is the lack of a standardized approach to reporting nutritional intake data and growth in the neonatal literature. Such variability makes comparisons amongst studies difficult and meta-analysis unreliable. We propose a core outcome set for neonatal nutrition and growth studies.
