【目的】 探讨特发性矮小(idiopathic short stature,ISS)患儿的智力水平和智力结构以及其持续注意力状况。 【方法】 采用中国韦氏儿童智力量表(C-WISC)对32例ISS患儿的智力结构进行测试,并与32例年龄和性别相匹配的正常儿童进行对照研究;且采用视听整合持续操作测试系统(IVA-CPT)对其中29例患儿进行了注意力测试。 【结果】 ISS组的总智商(full intelligence quotient,FIQ)、言语智商(verbal IQ,VIQ)和操作智商(performance IQ,PIQ)均在正常范围,与对照组比较差异无统计学意义(P>0.05),但言语量表中的知识量表分高于对照组(P<0.05),而操作量表中的图片排列量表分低于对照组(P<0.05);两组PIQ与VIQ差值率比较,ISS组高于对照组(P<0.05)。ISS组综合注意商数、视觉注意力商数、听觉谨慎商数、视觉警醒商数低于对照组,差异有统计学意义(P<0.05),其余商数两组得分差异无统计学意义(P>0.05)。 【结论】 ISS患儿智力水平正常,但智力结构不平衡;ISS患儿比对照组更容易发生注意缺陷多动障碍。

【Objective】 To investigate idiopathic short stature (ISS) children's intelligence level and intelligence structure, and its continued attention to the situation. 【Methods】 The intelligence were tested by Wechsler Intelligence Scale for Children- Chinese (C-WISC) in 32 children with ISS and in 32 normal children; and attention were tested by the integrated visual and auditory continuous performance test( IVA-CPT) in 29 children with ISS. 【Results】 The full intelligence quotient (FIQ), verbal IQ (VIQ) and Performance IQ (PIQ) in the ISS Group were in a normal range, compared with the control group no significant difference (P>0.05). But the knowledge scale score of the verbal scale was significantly higher (P<0.05), while picture arrangement scale score of the operating scale was significantly lower than the control group (P<0.05); The difference rate between VIQ and PIQ,ISS group was higher than the control group (P<0.05). In ISS group ,full scale attention quotient, visual attention quotient, auditory prudence quotient, visual vigilance quotient were significant lower than the control group (P<0.05),the other data had no significant difference between ISS group and control group(P>0.05). 【Conclusion】 ISS children have normal intelligence, but intelligence structural is imbalances; ISS children are more likely with attention deficit hyperactivity disorder than the control group.
