低出生体重儿近期生长发育随访结果分析

目的 :研究低出生体重对婴儿生长发育的影响。方法 :对 10 0例低出生体重儿 ( L BW)进行定期生长发育随访及神经运动检查 ,同期分娩的正常足月儿 4 3例做为对照组 ,14 3例婴儿 1周岁时均用 CDCC法进行智测。结果 :1周岁时 L BW组身高、头围与正常足月儿已无差异 ( P>0 .0 5 ) ,但体重 15 0 1～ 1999g组和≤ 15 0 0 g组体重仍明显低于正常足月儿 ( P<0 .0 5 ,P<0 .0 0 1) ;MDI(智力发育指数 )、PDI(运动发育指数 ) 2 0 0 0～ 2 4 5 0 g组与正常足月儿已无差异 ( P>0 .0 5 ) ,但 <2 0 0 0 g组 MDI、PDI明显落后于正常足月儿 ( P<0 .0 0 1)。结论 :低出生体重对婴儿的智能、运动发育有非常显著的负面影响

A Short-term Study of Development of Low Birth Weight Infants for 100 cases

Objective:To explore the short-term effect of low birth weight(LBW)on physical and mental development in infants.Methods:The physical,mental and psychomotor development of 100 LBW infants were regularly observed from birth till one year old and 43 full-term infants as controls.All infants received infant development test of Chid Development Center of China (CDCC),when they were one year old.Results:Both height and headcircumference in LBW group caught up with those infull-term infants( P >0.05),But in 1 501~1 999 g and≤1 500 g groups,the weight were lower than those in full-term infants.( P <0.05,0.001);In 2 000~2 045 g group,Both MDI(mental development index)and PDI(psychomotor development index)caught up with those in full-term infanes( P >0.05),But in <2 000 g group,bothMDI and PDI respectively were lower than those in full-term infants( P <0.001).Conclusion:It was very obvious that LBW had a negative effect on baby's mental and psychomotor development.
