The characteristics of catch-up growth in very low birth weight infants (VLBW) have not been clearly established. The aim of this study was to analyse the height catch-up and some associated factors in a cohort of VLBW (birth weight<1,500g) from birth to age 14 years.
We obtained retrospective data on weight and height at birth and ages one, 2, 3, 4, 6, 8, 10, 12 and 14 years in a cohort of 170 VLBW. We compared these anthropometric values with those documented in a control group.
Thirty-seven children (21.8%) were born with an extremely low birth weight and 32 (18.8%) extremely preterm. At 10 years of age, 7% of VLBW (1,000-1,500g) and 35% of extremely low birth weight (<1,500g) children had short stature (P=.001). Almost all VLBW children who had a normal height at ages 2, 4 and 10 years had exhibited adequate weight catch-up in previous evaluations. We found that extremely low birth weight and extremely preterm were independent predictors for inadequate height catch-up.
The growth pattern of VLBW children has specific characteristics. The catch-up in weight seems to be an important factor for catch-up in height, and therefore a thorough nutritional follow-up is recommended in these children.
极低出生体重儿（VLBW）追赶生长的特征尚未明确。本研究旨在分析一组出生体重<1500g的极低出生体重儿从出生到14岁的身高追赶情况及一些相关因素。
我们获取了170名极低出生体重儿队列中出生时、1岁、2岁、3岁、4岁、6岁、8岁、10岁、12岁和14岁时体重和身高的回顾性数据。我们将这些人体测量值与对照组记录的数据进行了比较。
37名儿童（21.8%）出生时为超低出生体重，32名（18.8%）为极早产儿。10岁时，1000 - 1500g的极低出生体重儿中有7%，超低出生体重（<1500g）儿童中有35%身材矮小（P = 0.001）。几乎所有在2岁、4岁和10岁时身高正常的极低出生体重儿在之前的评估中体重追赶情况良好。我们发现超低出生体重和极早产是身高追赶不足的独立预测因素。
极低出生体重儿的生长模式具有特定特征。体重追赶似乎是身高追赶的一个重要因素，因此建议对这些儿童进行全面的营养随访。
