Postnatal growth in terms infants born small for gestational age is associated with later neurocognitive and metabolic outcomes

Abstract

We systematically reviewed papers published in English between 1994 and October 2015 on how postnatal weight gain and growth affects neurodevelopment and metabolic outcomes in term-born small for gestational age (SGA) infants. Two randomised trials reported that enriched infant formulas that promoted early growth also increased fat mass, lean mass and blood pressure, but had no effect on early neurocognitive outcomes. Meanwhile, 31 observational studies reported consistent positive associations between postnatal weight gain and growth with neurocognitive outcomes, adiposity, insulin resistance and blood pressure
