Plain English Summary
Background and study aims
Human milk is the ideal food for all human babies and has a nutrient composition ideal for babies that have been born at full term. However, the protein and mineral content of human milk may not be sufficient for premature babies as they need more protein, sugars and fats for growth and development. Lack of nutrition of premature babies can lead to slower than usual growth and there are concerns regarding both the short and long-term neurodevelopment (brain and central nervous system development) of these babies. In this study, we are going to observe very premature babies, fed with their mother’s milk with blind macro nutrient content, fortified with standard human milk fortifier and protein supplementation according to ESPGHAN recommendations. We expect to find variation in the content of these nutrients and to see if that has some influence in body composition measured by somatometry and air plethismography as well as in neurodevelopment at 12 and 18 months of age.
Who can participate?
Premature babies of less than 34 weeks gestational age.
What does the study involve?
Immediately after discharge from hospital, the body composition of the babies included in the study is measured by plethismography, generally in the same day of other standard study. They all receive standard neonatal and after discharge care. At 12 months and again at 18 months, the neurodevelopment of all babies are assessed.
What are the possible benefits and risks of participating?
The study may give some insight in the need of macro-nutrient evaluation of feeding premature babies and may result in adjusting the nutrient content of supplements given. There are no expected risks, as it is an observational study and the follow up is the same for all the babies.
Where is the study run from?
Lisbon Central Hospital Centre (Portugal)
When is the study starting and how long is it expected to run for?
February 2014 to December 2014

Effect of different composition of human milk and its fortification in body composition and neurodevelopment in a cohort of very preterm infants: a observational cohort study
Preterm infants feed in the first weeks of life with recommended but different amounts of protein have different body composition (measured as % of FFM/FM) at 40 weeks gestational corrected age and different psychomotor development in the medium term.
