Postnatal weight gain during the first 8 weeks of life of 20 very low birthweight preterm infants (gestational age: 28.9 +/- 1.7 weeks, birthweight: 1098 +/- 199 g, mean +/- SD) was compared to the in utero weight gain of theoretical control fetuses. By the end of the study period preterm infants gained significantly less weight than their controls (155 +/- 15 vs 221 +/- 16%, p less than 0.001). During the first 6 weeks of life daily additional weight gain of the preterm infants was less than that of the controls, but after that time no significant difference was seen (7th-8th week: 12.0 +/- 3.6 vs 13.7 +/- 3.9 g/kg/day, study infants vs controls, ns). During the 7th-8th weeks of life positive correlation was found between calorie intake and weight gain (r = 0.33, F = 2.17, p less than 0.05). The changes in serum total protein and albumin levels, including an initial increase by the age of 2 weeks, were statistically not significant.
将20名极低出生体重早产儿（胎龄：28.9±1.7周，出生体重：1098±199克，均值±标准差）出生后前8周的体重增加情况与理论对照胎儿的宫内体重增加情况进行了比较。在研究期末，早产儿体重增加显著低于其对照胎儿（155±15对221±16%，p<0.001）。在出生后的前6周，早产儿每日额外体重增加低于对照胎儿，但此后未观察到显著差异（第7 - 8周：12.0±3.6对13.7±3.9克/千克/天，研究婴儿对对照胎儿，无显著性差异）。在出生后的第7 - 8周，发现热量摄入与体重增加之间存在正相关（r = 0.33，F = 2.17，p<0.05）。血清总蛋白和白蛋白水平的变化，包括在2周龄时最初的升高，在统计学上无显著意义。
