Abstract

Human milk, either from milk banks or as milk expressed by the baby’s own mother, is often considered the feed of first preference for low birthweight infants. Infant formulas (“preterm formulas”) are now available which have been designed to address the theoretical nutritional needs of growing low birthweight infants, and unlike previous formulas there is a deliberate departure in their design from the composition of human milk. A number of studies have shown that infants fed with banked human milk gain weight more slowly than do the infants fed with a “regular” 2.8 mJ/L (20 kcal/oz) commercial formula (1,2,3,4) and that the advantage in weight gain is even more striking when infants fed with 3.5 mJ/L (24 kcal/oz) formulas are compared to those fed with banked human milk (4,5,6). It has been demonstrated that in many of these studies the methods used for collecting human milk for banking resulted in a banked milk of exceptionally low nutrient content (5,6), and feedings with mother’s own expressed breast milk gave rates of weight gain comparable to those of infants fed with regular formula (3). Nevertheless, low birthweight infants fed with high-energy, protein and mineral containing “preterm” formulas appear to experience much greater weight gains than do infants fed with their own mother’s expressed breast milk.
