Abstract
Background/Objectives: Sleep problems affect the quality of life (QoL) and treatment prognosis of children with epilepsy (CWE). We analyzed sleep problems and QoL in CWE but without neurodevelopmental disorders, which affect sleep and QoL. We also examined discrepancies between child self-reports and parent proxy reports in QoL assessments. Methods: Thirty-two CWE in grades 2-6 (aged 7-12 years) in regular classes who attended Osaka Metropolitan University Hospital and PL General Hospital between January 2022 and August 2023 were compared with 21 children who had attended the hospitals for acute non-neurological disorders and had recovered (control group). Children with neurodevelopmental disorders, those unable to answer questionnaires, and those taking sleeping pills were excluded. Children in both groups completed the Kinder Lebensqualität Fragebogen (KINDL-R); their parents completed the KINDL-R and Japanese Sleep Questionnaire for Elementary Schoolers (JSQ-ES). Results: There were no significant differences in mean (±SD) JSQ-ES total scores between the epilepsy and control groups (71.6 ± 21.4 vs. 63.2 ± 15.2, respectively; p = 0.16). In the epilepsy group, there were no significant differences in total or subscale KINDL-R scores between children with (JSQ-ES ≥ 80) and without (JSQ-ES < 80) sleep problems. Correlation coefficients between child self-reports and parent proxy reports for KINDL-R total scores were 0.171 (p = 0.348) and 0.656 (p = 0.001) for the epilepsy and control groups, respectively. There was a significant difference between the total scores of children's self-reports and parents' proxy reports in the control (p = 0.008) group, but not in the epilepsy group (p = 0.837). Conclusions: Sleep problems may not have significant impacts on the QoL of CWE without neurodevelopmental disorders. Parents of CWE do not always correctly assess their children's QoL, so it is important to ask both children and their parents to obtain a comprehensive picture of their QoL.
