剖宫产对学龄期儿童注意力影响的研究

Attentiveness in school children: effect of cesarean section birth

摘要:

目的:探讨不同原因剖宫产对学龄期儿童注意力的影响。方法:将308例健康学龄期儿童分为自然分娩组（n＝105）、社会因素剖宫产组（n＝101）和医学指征剖宫产组（n＝102）。采用视听整合持续操作测试（IVA-CPT）进行注意力测试。结果:①三组间综合控制、听觉反应控制、综合注意、听觉注意力、视觉注意力、听觉警醒、视觉一致性、视觉警醒、视觉注意集中等9项商数差异有显著性（P＜0.05）；②医学指征剖宫产组IVA-CPT结果明显差于自然分娩组和社会因素剖宫产组，而社会因素剖宫产组与自然分娩组差异无显著性意义。结论:剖宫产手术本身对健康学龄期儿童的注意力无明显影响，影响剖宫产儿童注意力的真正原因是导致剖宫产的医学指征。［中国当代儿科杂志，2009，11（11）：913-916］

Abstract:

OBJECTIVE: To study the effect of cesarean section birth based on different indications on attentiveness in school children. METHODS: A total of 308 school children were assigned to three groups according to their birth model: natural delivery (n=105), cesarean section due to social factors (n=101) or medical factors (n=102). The integrated visual and auditory continuous performance test (IVA-CPT) was performed for assessing attentiveness. RESULTS: The IVA-CPT demonstrated that there were significant differences in the quotients of combination control, auditory response control, combination attention, auditory attention, visual attention, auditory vigilance, visual concordance, visual vigilance and visual attention among the three groups (P<0.05). The results of the IVA-CPT in the group of cesarean section due to medical factors was obviously poorer than that of the natural delivery group and the group of cesarean section due to social factors. However no significant differences were observed between the groups of natural delivery and of cesarean section due to social factors. CONCLUSIONS: Cesarean section itself has no significant impacts on attentiveness in school children, while medical indications for cesarean section may contribute to major cause of attention deficit disorder.［Chin J Contemp Pediatr, 2009, 11 (11):913-916］
