The aim of the present study was to evaluate changes in body composition in 48 preterm infants in relation to protein and energy intakes from term up to 3 months of corrected age, using air displacement plethysmography. Protein intake (grams per kilogram per day) was negatively associated with percentage of fat mass at 1 month of corrected age. The high-protein-intake group showed greater gain in lean body mass gain than did the low-protein-intake group. This finding suggests that during the first month of corrected age, high protein intake results in a significantly different weight gain composition.
本研究的目的是使用空气置换体积描记法评估48名早产儿从足月至矫正年龄3个月期间身体成分的变化与蛋白质和能量摄入量的关系。蛋白质摄入量（克/千克/天）与矫正年龄1个月时的脂肪量百分比呈负相关。高蛋白摄入组的瘦体重增加比低蛋白摄入组更大。这一发现表明，在矫正年龄的第一个月，高蛋白摄入会导致体重增加的组成有显著差异。
