Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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).

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

High protein supplementation

Infants will receive a diet that consists of mother's own milk or donor human milk and bovine-based human milk fortifier plus a fixed amount of commercially available hydrolyzed bovine protein. The study intervention will begin the day after fortification is ordered and will be continued until postnatal day 50 or 32 weeks postmenstrual age, whichever occurs first.

Group Type EXPERIMENTAL

High protein supplementation

Intervention Type DIETARY_SUPPLEMENT

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.

Standard protein supplementation

Infants will receive a standard diet that consists of mother's own milk or donor human milk (DHM) and bovine-based human milk fortifier. The study intervention will be continued until postnatal day 50 or 32 weeks postmenstrual age, whichever occurs first.

Group Type ACTIVE_COMPARATOR

Standard protein supplementation

Intervention Type DIETARY_SUPPLEMENT

Infants assigned to the standard protein supplementation group will receive fortified human milk (\< 4.5 g/kg/day of enteral protein)

High protein supplementation

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.

Intervention Type DIETARY_SUPPLEMENT

Standard protein supplementation

Infants assigned to the standard protein supplementation group will receive fortified human milk (\< 4.5 g/kg/day of enteral protein)
