Postnatal growth was followed in a population-based group of 123 small-for-gestational-age (SGA, birth weight < -2 SD) children (66 boys and 57 girls) to four years of age in order to determine the incidence and time of catch-up growth. Gestational age was determined by ultrasound in gestational weeks 16-17 in all pregnancies, thus eliminating the problem of distinguishing between SGA and preterm infants. Infants with well-defined causes for slow growth rate, i.e. those infants with chromosomal disorders, severe malformations, intrauterine viral infections or cerebral palsy, were excluded. The boys showed an extremely fast weight catch-up, 85% of them reaching weights greater than -2 SD at the age of three months and remaining above this level to the end of the study period. Such a fast catch-up growth was observed in only two-thirds of the girls, but at four years of age 85% of the girls were also above -2 SD. Length catch-up was more gradual than weight catch-up. Of the boys, 54% had lengths below -2 SD at birth, 26% at 1 year of age, 22% at 2 years of age, 17% at 2.5 years of age and 11% (n = 8) at 4 years of age. Corresponding figures for girls were: 69% at birth, 28% at 1 year, 15% at 2 years, 12% at 2.5 years and 5% (n = 3) at 4 years. At 4 years of age, only six boys and three girls remained below -2 SD for both weight and height.(ABSTRACT TRUNCATED AT 250 WORDS)
对一组基于人群的123名小于胎龄儿（SGA，出生体重＜-2标准差）儿童（66名男孩和57名女孩）进行出生后生长情况跟踪，直至4岁，以确定追赶生长的发生率和时间。所有妊娠在孕16 - 17周时通过超声确定孕周，从而消除了区分SGA和早产儿的问题。排除生长速率缓慢原因明确的婴儿，即患有染色体疾病、严重畸形、宫内病毒感染或脑瘫的婴儿。男孩体重追赶极快，85%的男孩在3个月大时体重超过-2标准差，并在研究期末保持在该水平以上。只有三分之二的女孩出现如此快速的追赶生长，但在4岁时，85%的女孩体重也超过了-2标准差。身长追赶比体重追赶更缓慢。男孩中，出生时54%的身长低于-2标准差，1岁时为26%，2岁时为22%，2.5岁时为17%，4岁时为11%（n = 8）。女孩的相应数据为：出生时69%，1岁时28%，2岁时15%，2.5岁时12%，4岁时5%（n = 3）。4岁时，只有6名男孩和3名女孩体重和身高均低于-2标准差。（摘要截选至250词）
