Abstract： 目的了解孕妇营养状况与胎儿发育迟缓(IUGR)及新生儿出生后视力发育障碍的关系.方法将60例住院产妇分为两组:即IUGR组与对照组,各30例.分析孕妇8种营养食品的摄取情况,用荧光法检测母血及脐血中维生素A含量,用吸收光谱法测定母血与脐血中铁、铜、锌含量,检测新生儿出生后3～7 d及出生后10个月时的闪光视觉诱发电位.结果与对照组相比,IUGR组孕妇的鸡蛋、猪肝与瘦肉的摄取量均明显减少(P＜0.05),母血及脐血中维生素A、铁含量显著降低(P＜0.01),脐血中锌含量降低(P＜0.05),新生儿闪光视觉诱发电位检测提示,三相波中波峰向上主波(P100)的潜伏期延长,幅值降低.结论孕期富含维生素A、铁与锌等营养成分的食物摄取减少与ICGR的发生密切相关,并可导致胎儿视觉发育障碍.
