Abstract

Abstract: Objective To investigate the physical growth of low birth weight infants from 0 to 3 years old in Shanghai Pudong district,and to master the different growth trajectories of preterm low birth weight infants and mature low birth weight infants. Methods Totally 387 low birth weight infants born from October 2014 to September 2016 in community health centers in Pudong district were selected as the observation group,and 386 normal infants with the same gender and age in the same community were selected as control group.The weight,body length and height of infants from 0 to 3 years old were compared. Results During the period from 0 to 3 years old,the weight and length/height of low birth weight infants lagged behind the control group (P<0.01).With the increase of age,the weight and height of premature infants at high risk group and low risk group were higher than those at full term infants with statistical significance (P<0.05).While there were no significant differences on weight and length/height between low-risk infants and high-risk infants (P>0.05).There was statistically significant difference on the overall weight among three groups of children with low birth weight from 0 and 3 years old (P<0.05),but no significant difference on height was found (P>0.05).The weight and length/height growth rate of high-risk premature infants and low-risk premature infants were higher than those of mature low birth weight infants and full-term normal infants. Conclusions There is catch-up growth in low birth weight infants from 0 and 3 years old.The growth trajectory of premature low birth weight infants is different from that of full-term infants,and low birth weight preterm infants may have greater growth potential.

摘要： 目的了解上海市浦东新区低出生体重儿童0～3岁体格生长状况,并掌握早产低出生体重儿和足月小样儿不同的生长轨迹。方法选取2014年10月-2016年9月出生并在浦东新区各社区卫生服务中心接受保健管理的387名低出生体重儿为观察组,并在同社区选取同性别同年龄段的386名正常儿童作为对照组,对其0～3岁期间的体重、身长/身高进行对比研究。结果 0～3岁期间,低出生体重儿的体重、身长/身高发育均落后于对照组(P<0.01);随着年龄增长,高危早产儿和低危早产儿的体重、身长/身高均赶超足月小样儿,且有差异统计学意义(P<0.05);高危早产儿和低危早产儿两组间的体重和身长/身高差异无统计学意义(P>0.05);三组低出生体重儿在0～3岁期间整体体重差异有统计学意义(P<0.05),但身高差异无统计学意义(P>0.05);高危早产儿和低危早产儿的体重、身长/身高长速均超过足月小样儿和足月正常儿童。结论低出生体重儿在0～3岁期间存在追赶性生长;早产低体重儿与足月小样儿呈现不同的生长轨迹,早产低体重儿可能具有更大的生长潜能。
