研究背景:小于胎龄(SGA)超低出生体重(ELBW)儿,通常比较矮小,或学习能力低下,或两种现象同时存在。适宜胎龄(AGA)的双胞胎或三胞胎儿童中,出生体重较小的儿童也可发生类似的问题。目的:评价小于胎龄的超低出生体重(SGAELBW)的双胞胎或三胞胎婴
Background: ELBW children younger than gestational age (SGA) are usually shorter, less able to learn, or both. A similar problem can occur in twins or triplets of suitable gestational age (AGA) among children of low birth weight. PURPOSE: To evaluate twin or triplets infants with very low birth weight (SGAELBW) of less than gestational age
