    Abstract:
    BACKGROUND: Post-discharge optimal growth and nutritional intake have beneficial effects for neurodevelopment in preterm very low birth weight infants (VLBWIs) with extrauterine growth retardation (EUGR). The present study aimed to compare the effects of a nutrient-dense formula (NDF) to a post-discharge formula (PDF) on post-discharge growth of preterm VLBWIs with EUGR. METHODS: Forty-eight preterm VLBWIs with EUGR at discharge were randomised to receive NDF (100 kcal per 100 mL; 2.6 g protein per 100 mL) or PDF (74 kcal per 100 mL; 1.95 g protein per 100 mL) for 1-6 months until body weight reached the 50th percentile on growth charts with corrected age. Volume, nutrient intake, anthropometry and biochemistry data were collected. RESULTS: Volume intake was lower in the NDF group than the PDF group during the first 2 months of feeding (P = 0.039 and 0.018, respectively).There were no significant differences in volume intake during months 2-6 of feeding. Energy, protein, carbohydrate and fat intake were higher in the NDF group during months 1-6 of feeding. There were no significant differences in weight, length, and head circumference Z-scores during months 1-6 between the two groups. The △length Z-score from discharge to month 6 was significantly higher in the NDF group than the PDF group (P = 0.043). No differences existed between the two groups with respect to biochemistry. CONCLUSIONS: After discharge, preterm VLBWIs with EUGR fed a NDF gain anthropometric parameter Z-scores similar to those for a PDF within 6 months of follow-up. A NDF leading to gain in length requires further follow-up.
