据报道，小于胎龄儿出生后的追赶性生长主要发生在生命的最初3-9个月。本研究描述了两个人群中出生时小于胎龄（GA）（出生身长< -2标准差评分[SDS]）的健康足月婴儿的出生后早期生长特征。1973年至1975年在瑞典哥德堡对139名出生时GA不足的婴儿进行了一项从出生到最终身高的纵向生长研究，并将结果与1995年至1996年对41名出生时GA不足的香港中国婴儿进行的持续详细的前瞻性6个月随访结果进行了比较。对于两个人群，使用出生时和出生后更新的瑞典生长参考数据，以SDS表示身高。在瑞典的研究中，92%出生时GA不足的儿童最终身高大于-2 SDS; 76%在2个月大时身高大于-2 SDS。在香港研究中，79%的儿童在5个月龄时身高达到-2 SDS以上（迄今为止最长的随访时间）。研究了1967年出生的第三批香港中国婴儿，其中65%在5个月大时达到正常身高范围。在后来的香港研究（1995-1996）中，早在12周龄时就可以确定追赶性生长，这对临床实践具有重要意义。因此，出生后第一周的生长监测提供了有用的信息，在出生时缺乏GA的婴儿追赶生长。
Postnatal catch-up growth in infants born small for gestational age has been reported to occur mainly during the initial 3-9 months of life. The study presented here characterized early postnatal growth in healthy, full-term infants born short for gestational age (GA) (< -2 standard deviation scores [SDS] in birth length) in two populations. Results from a longitudinal growth study from birth to final height of 139 infants born short for GA between 1973 and 1975 in Goteborg, Sweden, were compared with results from an ongoing detailed prospective 6-month follow-up of 41 Hong Kong Chinese infants born short for GA in 1995 and 1996. For both populations, height was expressed in SDS using the updated Swedish growth reference data at birth and postnatally. In the Swedish study, 92% of the children born short for GA reached a final height greater than -2 SDS; 76% had a height greater than -2 SDS by 2 months of age. In the Hong Kong study, 79% reached a height greater than -2 SDS by 5 months of age (the longest follow-up time to date). A third population of Hong Kong Chinese infants born short for GA in 1967 was studied; 65% had reached the normal height range by 5 months of age. In the later Hong Kong study (1995-1996), catch-up growth could be identified as early as 12 weeks of age, which has important implications for clinical practice. Thus, growth monitoring during the first weeks of postnatal life gives useful information on catch-up growth in infants born short for GA.
