Mineral balance and bone mineral content (BMC) in very low birth weight(VLBW) infants fed new protein hydrolysate preterm formula (HPTF) or standard preterm formula (PTF). 1411

A decrease in mineral utilization has been reported in VLBW infants fed HPTF (Rigo Acta Paediatr 1995). Subjects and methods: Bone mineral accretion was evaluated in 16 VLBW infants randomly designed to receive HPTF(n=9, BW=1183±242 g, GA=28.9±1.7 wks) or PTF (n=7, BW=1139±162 g, GA=27.7 ±1.0 wks) from inclusion until theoretical term. Vitamine D supplementation (800 IU/d) was given in both groups. A 3-day metabolic balance was performed at the end of the first month of life and gain in BMC was measured (dual x-ray absorptiometry-DXA) between time of discharge and theoretical term. Table

Table 1

According to nutritional balance, mineral retention was higher in infants fed HPTF than in those fed PTF; on contrast, gain in BMC between discharge and theoretical term tended to be lower in HPTF group.
