Measurements of weight, head circumference, crown-heel length, crown-rump length, rump-heel length and limb lengths were made in 514 neonates. From these measurements the differences in trunk and limb growth and their relations with head growth and body weight were examined in small-for-gestation (SGA) and appropriate grown (AGA) infants, and in different ethnic groups. We found that Asian infants had different body proportions from blacks and whites, with shorter trunks and forearms. SGA infants as a whole showed little difference in proportions from AGA infants except in their ponderal indices and the ratio of head size to body weight. However there was a preponderance of thin, relatively well-grown infants among them. When very short SGA infants were compared with AGA infants significant differences emerged, the short infants of all ethnic groups having shorter trunks and forearms in relation to their other measurements. We found no evidence of relative sparing of head growth. The results suggest that infants with prolonged intrauterine growth retardation are most likely to have disturbed skeletal proportions.
对514名新生儿进行了体重、头围、顶跟长度、顶臀长度、臀跟长度和肢体长度的测量。根据这些测量结果，研究了小于胎龄儿（SGA）和适于胎龄儿（AGA）以及不同种族群体中躯干和肢体生长的差异及其与头部生长和体重的关系。我们发现，亚洲婴儿与黑人和白人的身体比例不同，躯干和前臂较短。SGA婴儿总体上与AGA婴儿在比例上差异不大，只是在其 ponderal 指数以及头围与体重的比例方面有所不同。然而，其中瘦但相对生长良好的婴儿占多数。当将非常短小的SGA婴儿与AGA婴儿进行比较时，出现了显著差异，所有种族的短小婴儿相对于其他测量值而言，其躯干和前臂较短。我们没有发现头部生长相对 spared 的证据。结果表明，宫内生长迟缓时间延长的婴儿最有可能骨骼比例失调。
