Impact of macronutrient supplements on later growth of children born preterm or small for gestational age: a systematic review and meta-analysis of randomised and quasi-randomised controlled trials

We undertook a systematic review and meta-analysis of the available evidence from published studies that explore the effects of macronutrient supplements given to preterm and small-for-gestational-age infant on their growth after hospital discharge. We found no evidence that early macronutrient supplementation for infants born small altered body mass index (BMI) in childhood. Although supplements appeared to increase weight and length in toddlers, effects were inconsistent and unlikely to be clinically significant. Limited data suggested that supplementation increased fat mass in childhood, but these effects did not persist in later life.
