Abstract

Background: Human milk (HM) is the first choice for preterm infants, but exclusive HM feeding is inadequate for the growth of very preterm infants. The hypothesis of this trial is that infants fed according to an individualized fortification regimen will have higher protein intake and improved weight gain velocity (WGV).

Methods: A prospective, randomized, controlled study was conducted. Infants <34 weeks of gestational age were enrolled when enteral feeding volume reached 60 mL/kg/d and were randomly allocated to the individualized fortification (IF) group or the standard fortification group. The IF group was fed using a regimen that featured modifying HM fortifier and supplemental protein powder based on the protein concentration in HM, current body weight of infants, and blood urea nitrogen (fortification level was set as L-1, L0, L1, L2, L3; the amount of HM fortifier and protein powder were determined accordingly).

Results: Between September 2012 and August 2016, 51 preterm infants completed the study. In the IF group, 62.5% (15/24) of preterm infants were fed with HM fortified to level 1, 29.2% (7/24) to level 2, and 12.5% (3/24) to level 3. The WGV of the third week in the IF group was greater than the standard group (20.8 ± 7.9 vs 14.9 ± 4.5 g/kg/d, P = 0.022).

Conclusion: About two-thirds of preterm infants needed to adjust the HM fortification to a higher level. The WGV of infants in the IF group was better than that of the standard group in the third week of this study.
