Formula milk versus maternal breast milk for feedingpreterm or low birth weight infants

Abstract

Background: Maternal breast milk may contain less nutrients than artificial formula milk but may confer important non-nutrient advantages for preterm or low birth weight infants. Objectives: To determine the effect of feeding with formula milk compared with maternal breast milk on rate of growth and developmental outcomes in preterm or low birth weight infants. Search strategy: The standard search strategy of the Cochrane Neonatal Review Group was used. This included electronic searches of the Cochrane Central Register of Controlled Trials Register (CENTRAL, The Cochrane Library, Issue 3, 2007), MEDLINE (1966 - June 2007) and EMBASE (1980 - June 2007) and CINAHL (1982 to June 2007) (all accessed via OVID) and previous reviews including cross references. Selection criteria: Randomised controlled trials comparing feeding with formula milk versus preterm human milk in preterm or low birth weight infants. Data collection and analysis: The standard methods of the Cochrane Neonatal Review Group were used, with separate evaluation of trial quality and data extraction by two authors. Main results: No eligible trials were identified. Authors' conclusions: There are no data from randomised trials of formula milk versus maternal breast milk for feeding preterm or low birth weight infants. This may relate to a perceived difficulty of allocating an alternative feed to an infant whose mother wishes to feed with her own breast milk. Maternal breast milk remains the default choice of enteral nutrition because observational studies, and meta-analyses of trials comparing feeding with formula milk versus donor breast milk, suggest that feeding with breast milk hasmajor non-nutrient advantages for preterm or low birth weight infants.
