In order to assess the potential for "catch-up" growth of the head in "symmetrically" growth retarded infants and the influence of neonatal nutrition, head growth over the first year of life in 18 preterm infants with severe intra-uterine retardation of head growth, but who were otherwise normal, was examined retrospectively. All were delivered before 34 weeks of gestation and, except for 1 with cerebral palsy, showed a significant "catch-up" in head circumference by 10 months post term, with 8/18 stabilizing on or above the fiftieth centile (Fig. 1). This suggests that the reduction in head size in such infants is due to factors extrinsic to the fetus, rather than to a reduced fetal growth potential. Differences in protein and calorie intakes in the neonatal period did not appear to influence the "catch-up".
为了评估“对称”生长迟缓婴儿头部“追赶性”生长的潜力以及新生儿营养的影响，我们回顾性研究了18例严重宫内头部生长迟缓但其他方面正常的早产儿出生后第一年的头部生长情况。所有婴儿均在妊娠34周前出生，除1例患有脑瘫外，其余婴儿在足月后10个月时头围均有显著的“追赶性”生长，18例中有8例稳定在或高于第50百分位（图1）。这表明此类婴儿头部尺寸减小是由于胎儿外部因素，而非胎儿生长潜力降低。新生儿期蛋白质和热量摄入的差异似乎并未影响“追赶性”生长。
