小于胎龄儿过快追赶生长与儿童期肥胖关系的研究

Research progress in the relationship between rapid catch-up growth and childhood obesity in small for gestational age infants

由于宫内生长受限的解除以及出生后的营养环境改变,大部分小于胎龄(SGA)儿都会出现追赶生长。追赶生长可以促进SGA儿的体格发育,提高生存质量。近年来许多研究表明SGA儿过快追赶生长与儿童期肥胖密切相关,母乳喂养可降低肥胖的发生率。本文就SGA儿过快追赶生长与儿童期肥胖关系、可能机制的研究进展做一综述。

Because of the lifting of intrauterine growth restriction and the altered nutritional environment after birth,most small for gestational age(SGA)would have catch-up growth.Catch-up growth can promote the physical development and improve the quality of survival of SGA.Recently,there is much evidence that rapid catch-up growth is associated with childhood obesity,while breastfeeding can reduce the incidence of obesity.This article reviews the progress in the relationship between rapid catch-up growth of SGA and childhood obesity,and discusses possible mechanisms.
