遗尿症患儿智力水平和智力结构分析

Intelligence level and intelligence structure of children with primary nocturnal enuresis

目的有文献报道原发性夜间遗尿症(PNE)患儿存在注意力/记忆力缺陷,并认为这种缺陷可能与患儿的智力情况有关,因此该研究对PNE患儿的智力水平和智力结构进行分析。方法采用中国韦氏儿童智力量表(C-WISC)对40例PNE患儿的智力结构进行测试,并与40例年龄和性别相匹配的正常儿童进行对照研究。结果PNE组的总智商(FIQ)、言语智商(VIQ)和操作智商(PIQ)均在正常范围,与对照组比较差异无显著性(P>0.05),但数字广度、编码、知识与算术分测验量表分与对照组比较差异有显著性(P<0.05);记忆/不分心因子(M/C)与对照组比较差异有显著性(P<0.05);两组PIQ与VIQ差值比较,差异无显著性(P>0.05)。结论PNE患儿智力水平正常,但智力结构中的记忆/不分心因子存在一定缺陷,提示可能与大脑额叶执行功能异常有关。

Objective Some research has shown that there may be memory/caution （M/C） defects in children with primary nocturnal enuresis （PNE）. This study aimed to investigate whether the defects affect the intelligence level and the intelligence structure in PNE children. Methods Intelligence tests were performed by means of Wechsler Young Children Scales of Intelligence （ C-WISC ） in 40 children with PNE and 40 age-matched normal children. Results The full intelligence quotient （FIQ）, verbal IQ （VIQ） and performances IQ （PIQ） in the PNE group were in a normal range and did not different from the control group. There were significant differences in the scores for digit extent, decipher, knowledge and arithmetics between the PNE and the control groups （ P 〈 0.05 ）. M/C factor in the PNE group was statistically lower than in the control group （93.44 ± 11.27 vs 100.03 ± 11.79 ; P 〈 0.05 ）. Conclusions The total intelligence level of children with PNE was normal, but the M/C factor in the intelligence structure had some defects, suggesting that PNE may be related to the abnormity of executive function in the frontal lobe.
