Infants delivered preterm often reflect accelerated maturation. The present study examines the occurrence of suboptimal intrauterine growth in infants delivered preterm by comparing their birth weights to the weights sonographically predicted for in utero fetuses at similar gestational ages but who ultimately deliver at term. Two weight-predicting formulas based on different sonographic parameters were used. In the fifth, tenth, and 50th percentiles of birth weight, the predicted weights were persistently and significantly greater than the actual birth weights between 24 and 31 weeks' gestation. The results of this model support the concept that the growth of infants delivered prematurely has been suboptimal. The authors hypothesize that preterm delivery may be in some instances another manifestation of the same underlying stress that hastens pulmonary and neurologic maturity.
早产婴儿往往反映出加速成熟。本研究通过比较早产婴儿的出生体重与超声预测的相似孕周但最终足月分娩的宫内胎儿体重，来检查早产婴儿宫内生长发育欠佳的情况。使用了基于不同超声参数的两种体重预测公式。在出生体重的第五、第十和第五十百分位数中，在孕24至31周之间，预测体重始终显著高于实际出生体重。该模型的结果支持了早产婴儿生长发育欠佳这一概念。作者推测，在某些情况下，早产可能是加速肺和神经成熟的相同潜在应激的另一种表现。
