Abstract

Abstract: In recent years,an increasing number of small-for-gestational-age(SGA) infants are seen among live birth. SGA infants,a special group of neonates, have considerable impact on children's health during their development both in the short- and long-term periods. Through the statistical analysis of the birth cohort of the newborns,there is a comprehensively epidemiological document of SGA. At the same time,etiological study on SGA has also reached new depth with focus on the maternal,placenta and fetus. This review mainly introduces the epidemiological features and etiological mechanism of SGA.

Key words: Small-for-gestational-age infants, epidemiology, maternal, placenta, fetal

摘要： 近年来小于胎龄儿(SGA)在活产婴儿中所占的比例不断增加,作为新生儿中的特殊群体,SGA对儿童生长发育的近期及远期健康影响均较大。通过对新生儿出生队列的统计学分析,得出了较为完善的SGA的流行病学资料。同时,关于SGA的病因学研究也日渐深入,主要涉及母体、胎盘、胎儿三方面。因此,本文主要从SGA的流行病学特点及病因学机制等方面进行综述。
