Abstract
Background/Aims: Human milk fortification has been advocated to enhance premature infants’ growth. We, therefore, undertook this study of a new human milk fortifier containing more protein than a reference one. Methods: Open, randomized, controlled, multiclinic trial, with weekly growth parameters and safety evaluations in premature infants <1,500 g. Results: The 2 groups did not differ in demographic and baseline characteristics. The adjusted daily milk intake was significantly higher in the infants fed reference human milk fortifier (n = 29; 154.2 ± 2.1 vs. 144.4 ± 2.5 ml/kg/day, mean ± SE; p < 0.05). Both human milk fortifiers produced increases over baseline in weight, length, and head circumference, with greater gains observed in the new human milk fortifier-fed infants for the former two parameters (weight gain 26.8 ± 1.3 and 20.4 ± 1.2 g/day, p < 0.05; head circumference 1.0 ± 0.1 and 0.8 ± 0.1 cm/week; length 0.9 ± 0.1 and 0.8 ± 0.1 cm/week, respectively). Serum chemistries were normal and acceptable for age. Study events were typical for premature infants and similar in both groups. Conclusions: This new human milk fortifier had comparable safety to the reference human milk fortifier and promoted faster weight gain and head circumference growth.
