Analysis of factors related to low health-related quality of life in children with epilepsy using a self-assessed Japanese version of the KIDSCREEN-52

Background: There is a paucity of studies on self-assessed generic health-related quality of life (HRQOL) in children with epilepsy. The purpose of this study was to investigate generic HRQOL and associated factors among Japanese children with epilepsy.

Methods: In this clinic-based study, 277 children (aged 8-18 years) with epilepsy and 429 children without any chronic illnesses were recruited. HRQOL was evaluated using the Japanese version of the KIDSCREEN-52 self-reported questionnaire, which consisted of 52 items categorized into 10 dimensions related to the environment surrounding children. Multiple regression analysis was applied to explore related factors with low HRQOL in each dimension.

Results: We obtained the questionnaire from 171 (61.7%) and 306 (71.3%) children in the epilepsy and control groups, respectively. Short treatment period (<2 years), seizure lasting >30 min, and post-ictal symptoms were associated with a low HRQOL for School Environment (OR: 3.81; 95% CI: 1.34-10.86), Moods & Emotions (OR: 3.82; 95% CI: 1.67-8.78), and Parent Relations & Home Life (OR: 3.53; 95% CI: 1.29-9.72) dimensions, respectively. Complex neurodevelopmental disorders were associated with a low HRQOL for Social Support & Peers (OR: 3.59; 95% CI: 1.33-9.66), School Environment (OR: 2.49; 95% CI: 1.07-5.77), and Psychological Well-being (OR: 3.47; 95% CI: 1.20-10.00) dimensions.

Conclusions: Our results suggest that early psychosocial support and better management of epilepsy may improve HRQOL. More support in school environments may be required for children with epilepsy and neurodevelopmental disorders.
