OBJECTIVE: To study the intelligence level and structure in school age children with fetal growth restriction (FGR). METHODS: The intelligence levels were tested by the Wechsler Children Scales of Intelligence (C-WISC) in 54 children with FGR and in 84 normal children. RESULTS: The full intelligence quotient (FIQ), verbal IQ (VIQ) and performance IQ (PIQ) in the FGR group were 105.9±10.3, 112.4±11.2 and 97.1±10.6 respectively, and they all were in a normal range. But the PIQ was significantly lower than that in the control group (104.8±10.5; P<0.001), and the picture arrangement and the decipher subtest scores were significantly lower than those in the control group (P<0.01). The scores of perception/organization and memory/attention factors in the FGR group were 99.8±11.1 and 116.3±14.4, respectively, which were inferior to those in the control group (104.6±11.5 and 113.4±14.5 respectively; P<0.05). CONCLUSIONS: The total intelligence level of children with FGR is normal, but there are imbalances in the intelligence structure and dysfunctions in performance ability related to right cerebral hemisphere. Performance trainings should be done from the infancy in children with FGR.［Chin J Contemp Pediatr, 2009, 11 (10):833-835］
