Group 3 underwent clinical interview and neurocognitive assessment.Results. Verbal Intelligence Quotient (VIQ), Performance Intelligence Quotient (PIQ) and Full-Scale Intelligence Quotient (FSIQ) were lower in groups 1 e 2 than in controls (VIQ 98,11 ± 12,68 vs 91,78±16,11 vs 109,63±12,04; PIQ: 100.63±14.98 vs 93.92±14.89 vs 117.27±11.96; FSIQ: 96.75±13.51 vs 91.81±13.97 vs 114.93±11.05, respectively) (p<0.05).A positive correlation between PIQ and age of onset of SDB (r= 0,335, p=0,04) was found in group 1. A positive correlation between VIQ and age of onset of SDB (r=0,335, p=0,05) and a negative correlation between VIQ and duration of SDB (r=-0,362, p=0,02) PIQ and BMI percentile (r=-0,341, p=0,03), FSIQ and Apnea/Hypopnea index (r=-0,321, p=0,05) were found in group 2.ADHD scores correlated negatively with IQ scores in all subjects. Group 1 had the highest hyperactivity score.Conclusions. Children with obesity and SDB showed the highest cognitive impairment while children with only SDB the highest hyperactivity score. ER -
