  • Title: Extrauterine growth restriction in very-low-birthweight infants.
    Author: De Curtis M, Rigo J.
    Journal: Acta Paediatr; 2004 Dec; 93(12):1563-8. PubMed ID: 15841762.
    Abstract:
    UNLABELLED: Postnatal growth failure of very-low-birthweight (VLBW) infants may result from a complex interaction of genetic and environmental factors, including inadequate nutrition, morbidities affecting nutrient requirements, endocrine abnormalities and treatments. Among VLBW infants, those small for gestational age (SGA) at birth and those with postnatal growth restriction at the time of discharge are at higher risk of later growth failure and long-term consequences. Nutritional intervention with an "aggressive nutrition" during the first weeks of life may be able to minimize the interruption of nutrients that occurs at birth, and reduce as much as possible the incidence of growth restriction at the time of discharge and later. Even though aggressive parenteral and enteral nutrition appear to be effective and safe in VLBW infants, further evaluations of their long-term effect on growth and health consequences are needed. Several studies evaluating the effect of enriched nutrient formulas after hospital discharge on growth and neurodevelopment have produced conflicting results, whereas the potential deleterious long-term effects of prolonged use of high protein and/or of later catch-up growth have been questioned. In contrast, recent data seem to indicate that the use of human milk after hospital discharge could be the most beneficial diet for subsequent health and development. CONCLUSION: VLBW infants SGA at birth and those with early postnatal growth restriction are at high risk of later growth failure and long-term consequences. Therefore, the first objective of early nutrition should be to reduce the incidence of growth restriction at the time of discharge. Further studies on VLBW infants to evaluate the safety and beneficial effects of prolonged dietary manipulation during the first year of life are needed.
