Abstract
In litterature, there are discrepancies about nutrient and energy metabolism in SGA premature infants; that could be related to differences in type of intrauterine growth retardation. This study compares results of anthropometric data, 3-day nutritional balance and indirect calorimetry measurements performed in 8 AGA and 8 symmetrically growth retardated infants, at the same post-natal age. Infants were fed pooled HM protein and energy supplemented (HM fortifier: Eoprotin®, Milupa).
Volume of milk intake, amounts of nitrogen and energy intake were similar in both groups. There was no significant difference in protein and energy absorption, but SGA infants tended to present a better fat absorption, likely because they were 3 weeks older. Weight gain and it's composition were similar in both groups, with approximately 20% of fat (non-protein energy deposition). In conclusion, there was no significant difference in response to diet between AGA and SGA VLBW infants. Nutritional needs seem to be similar in AGA and SGA infants, as long as growth retardation is syrnmetrical. This may be different when asymmetrically growth retardated infants are concerned.
