【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.
