This study compared nutrient utilization and postnatal weight gain composition in eight appropriate for gestational age (AGA: birth weight 1293 +/- 107 g; gestational age 28.8 +/- 1.4 weeks) and eight symmetrically growth-retarded (SGA: birth weight 1110 +/- 230 g; gestational age 32.7 +/- 1.9 weeks), very low-birth-weight (VLBW) infants. There was no significant difference in protein, mineral and energy intake between AGA and SGA infants. Nitrogen absorption (84 +/- 3 and 83 +/- 4%) and nitrogen retention (356 +/- 48 and 352 +/- 43 mg/kg/day) were similar in both groups. Fat absorption tended to be lower in AGA (78 +/- 15%) than in SGA (87 +/- 4%) infants. Calcium, phosphorus and magnesium absorptions were similar in AGA and SGA infants. Metabolizable energy utilization was similar in both groups; about 55% was expended and 45% stored in new tissues. Energy expenditure was 58 +/- 4 kcal/kg/day in SGA infants and 61 +/- 9 kcal/kg/day in AGA infants. Weight gain and its composition were similar in both groups. We conclude that nutrient and energy utilization are similar in AGA and symmetrically growth-retarded, VLBW infants.
本研究比较了8名适于胎龄（AGA：出生体重1293±107g；胎龄28.8±1.4周）和8名对称生长受限（SGA：出生体重1110±230g；胎龄32.7±1.9周）的极低出生体重（VLBW）婴儿的营养物质利用情况和出生后体重增加的构成。AGA和SGA婴儿在蛋白质、矿物质和能量摄入方面无显著差异。两组的氮吸收（84±3%和83±4%）和氮潴留（356±48和352±43mg/kg/天）相似。AGA婴儿的脂肪吸收（78±15%）倾向于低于SGA婴儿（87±4%）。AGA和SGA婴儿的钙、磷和镁吸收相似。两组的可代谢能量利用相似；约55%用于消耗，45%储存于新组织中。SGA婴儿的能量消耗为58±4kcal/kg/天，AGA婴儿为61±9kcal/kg/天。两组的体重增加及其构成相似。我们得出结论，AGA和对称生长受限的VLBW婴儿在营养物质和能量利用方面相似。
