Protein supplementation, Human milk fortification
Brief summary
The study hypothesis is that, in human milk-fed extremely preterm infants, higher protein intake compared to usual protein intake reduces percent body fat (%BF) at 3 months of age.
Detailed description
Qualifying participants will be randomly assigned to receive either standard protein supplementation (control group) or high protein supplementation (intervention group). Intervention group: A fixed amount of commercially available hydrolyzed bovine protein will be added to fortified human milk after establishment of full enteral feeding. Control group: Hydrolyzed bovine protein will not be added to fortified human milk after establishment of full enteral feeding. If parent agrees, stool dirty diapers will be collected 2 times (at the time of hospital discharge and at 3 months of corrected age).
Interventions
To increase protein content of human milk, a fixed amount of commercially available hydrolyzed bovine protein will be added to fortified human milk. With this pragmatic approach, preterm infants assigned to the high protein supplementation group will receive \> 4.5 g/kg/day of enteral protein after establishment of full enteral feeding.
Infants assigned to the standard protein supplementation group will receive fortified human milk (\< 4.5 g/kg/day of enteral protein)
