摘　　要：不同出生体重及胎龄的新生儿在婴儿期呈现不同的生长方式,足月儿体重和身长在第2个月有一生长高峰:高出生体重儿生后头两个月显示“低速”生长趋势,但实际生长值始终高于正常儿组;足月小样儿在第1年展示不同程度的追赶生长,尤其在前半年。然而1岁时并未达到正常儿生长水平,并且也落后于早产儿;早产儿生长与胎龄有关,“足月”前显示缓慢增长,“足月”后加速生长。A longitudinal study on growth of infants from birth to 12 months was conducted which was aimed at a comparison of different growth pattern of infants with different birth weight and gestational age. 132 of infants being observed were divided into four groups. The study showed that the peak velocities of weight and length were taken place in the second month for not-preterm infants. In LGA group, even through the growth increased at lower rate during the period of first two months,the attained value of growth have always heen higher than that in other groups anyway. SGA infants appeared to exhibit catch up growth with different rate in the first year,especially in the first 6 months after birth,bur they did not achieve the attained value at 12 month of age as FGA group did, meanwhile they have also laged behind that of preterm infant group. The growth pattern in preterm infants dependented on the gestational age they had at birth. Before'term to be reached' ,their growth velocity was slower and after that it became rapid.
