早期干预对早产儿智能影响的研究

目的：研究早期干预对早产儿的智能发育的影响。方法：将60名早产儿分为两组，一组接受培训中心有关早期干预的措施称早产儿干预组，另一组为早产儿对照组。另将30名足月健康儿作为正常对照组，三组小儿及家长均参加定期的常规儿童保健门诊检查和指导，并均于1岁和1岁半时采用张家健等0－4岁小儿发育诊断量表评定发育商（DQ）。结果：早产儿干预组和正常对照组的DQ无差别（P＞0．05），这两组DQ都明显高于早产儿对照组（P＜0．01）。两组早产儿1岁半时的DQ均较1岁时提高（P＜0．01），正常对照组则提高不明显（P＞0．05），说明早产儿在1岁至1岁半期间明发展较足月健康儿快。此外，早产儿有2例智能低下（DQ＜70），早产儿干预组则没有。结论：早期干预可有效地促进早产儿的智能发育。

Early Intervention onIntelligent Development of Premature Infant

Objective: To study the effect of early intervention on intel1igent deve1opment of premature infant.Method: 60 premature infants were divided into two groups: intervention group in the training center and premature control group. Other 30 full- term infants were collected as normal control. All infants of the 3 groups and their family master were followed in out- patient clinic for regular medical exaamination and guidance in children health. They were all assessed with the Developmental Diagnostic Scale of Children aged 0～4 years of Zhang Jiajian. At the age of 1 and 1.5 year- old, they were examined in DQ (development quotient) . Results: There was no difference of DQ at age I between intervention group and normal control (p ＞ 0.05) . Both of them showed higher DQ than premature control (p ＜ 0.01) . Compared with DQ at age 1, premature infants (both intervention group and premature control group) had higher DQ at age 1.5, while nornal infants had no significant progress. There were two case of low intelligence (DQ ＜ 70) in premature control group at age 1.5, but no such case in intervention group. Conclusion: Early intervention has a positive effect on intelliqent development of premature infant.
