Abstract Mkid 116

Although hyperactivity is reported to be common among children with suspected sleep disordered breathing (SDB), the spectrum of behavioral abnormalities in these children is uncertain. The aim of this study is to survey behavioral abnormalities seen in children with suspected SDB. We compared the scores from the Child Behavior Checklist of 32 suspected SDB children with those of 137 age-matched healthy children. The CBCL we used (a Japanese version of the CBCL for ages 4 through 18 years) has 113 questions that are classified into 8 categories. On this CBCL, the higher the score, the more likely is the child to have problems. We also performed one-night polysomnography on the 32 suspected SDB children and compared the SDB measures obtained from polysomnography with the CBCL scores. Suspected SDB children showed higher scores on attention, withdrawal, somatic complaints, anxiety/depression, social problems and thought problems than in the controls. However, the severity of SDB failed to significantly elevate the scales of each CBCL category. Suspected SDB children had more behavioral problems than age-matched healthy children. The spectrum of behavioral abnormalities in suspected SDB children is wider than previously recognized. The factors causing behavioral problems in suspected SDB children remain unknown.
