Energy balance, nitrogen balance, and growth studies were done in 37 preterm infants (20 of very low birthweight) who were fed on expressed breast milk or on one of 3 formulae each of different composition, including a special premature formula and a highly adapted 'humanised' formula. The variability of breast milk composition was such that it would have been difficult to predict the infants' protein and energy intakes under normal nursing conditions. All measured parameters of nutritional performance were best in infants fed on the 'premature' formula and were reflected in greater weight gain, linear growth, and head growth. The nitrogen balance data suggest that the highly adapted formula, which had a protein content comparable with that of mature human milk, contained too little protein for small preterm infants.
对37名早产儿(其中20名极低出生体重儿)进行了能量平衡、氮平衡及生长研究,这些婴儿喂食的是挤出的母乳或三种不同成分配方奶中的一种,包括一种特殊的早产儿配方奶和一种高度适配的“人乳化”配方奶。母乳成分的变异性使得在正常哺乳条件下很难预测婴儿的蛋白质和能量摄入量。所有营养表现的测量参数在喂食“早产儿”配方奶的婴儿中最佳,这体现在体重增加、线性生长和头部生长方面更为显著。氮平衡数据表明,蛋白质含量与成熟母乳相当的高度适配配方奶,对于早产小婴儿来说蛋白质含量过低。
