Information on the likelihood of catch up growth in poorly grown very low birthweight children is sparse. The centiles for weight, height, and head circumference were recorded at both 2 and 5 years of age for 135 very low birthweight children and 42 normal birthweight children. At both ages significantly more children of very low birth weight were under the 10th centile for weight and height. Children of birth weight under 1000 g were more often under the 10th centile for weight at 5 years compared with those of birth weight 1000-1500 g. Mean incremental weight gain between 2 and 5 years was significantly less for very low birthweight children. Mean increment in weight from 2 to 5 years was less for very low birthweight children who had been under the 10th centile for weight at 2 years; children who had been under the 10th centile for height also had lower mean height increments. The growth centiles achieved by 2 years of age were useful predictors of poor growth at 5 years, with perinatal data of marginal importance. Only six of 43 (14%) children with a weight at 5 years of age under the 10th centile were small for gestational age at birth. Very low birthweight children who had a weight or height under the 10th centile at 2 years of age usually remained in this category at 5 years with no evidence of catch up growth.
关于生长发育不良的极低出生体重儿童追赶生长可能性的信息十分稀少。对135名极低出生体重儿童和42名正常出生体重儿童在2岁和5岁时记录了体重、身高和头围的百分位数。在这两个年龄段，极低出生体重儿童体重和身高低于第10百分位数的人数显著更多。出生体重低于1000克的儿童在5岁时体重低于第10百分位数的情况比出生体重在1000 - 1500克的儿童更常见。极低出生体重儿童在2岁至5岁期间的平均体重增加显著较少。2岁时体重低于第10百分位数的极低出生体重儿童在2岁至5岁期间的体重平均增加较少；身高低于第10百分位数的儿童平均身高增加也较低。2岁时达到的生长百分位数是5岁时生长不良的有效预测指标，围产期数据的重要性不大。43名5岁时体重低于第10百分位数的儿童中只有6名（14%）出生时为小于胎龄儿。2岁时体重或身高低于第10百分位数的极低出生体重儿童在5岁时通常仍处于这一类别，没有追赶生长的迹象。
