To compare growth velocity (GV) in preterm infants fed mother's own milk (MOM) fortified with human milk-based fortifier (HMBF) to those who received donor human milk (DHM) fortified with HMBF.
Study Design:
A retrospective study of preterm infants with birth weight <1,250 g receiving an exclusive human milk diet. Maternal and infant charts were reviewed for feeding, growth, and short-term neonatal morbidities.
Results:
On regression analysis, after adjusting (gestational age, multiple births, antenatal steroids, and small for gestational age), no significant difference was observed between the two groups in GV from birth to 32 weeks postmenstrual age (β-coefficient 0.83, 95% confidence interval [CI]: −0.47 to 2.14, p = 0.21), GV from the day of regaining of birth weight to discharge (β-coefficient −0.015, 95% CI: −1.08 to 1.05, p = 0.98). The rate of Grade 3 and 4 intraventricular hemorrhage was significantly higher in the DHM group (19.6% compared to 5.5% in MOM, p = 0.03).
Conclusion:
At our institution, there was no difference in GV of preterm infants fed HMBF-fortified MOM versus HMBF-fortified DBM.
