Exploring the association between perceived excessive daytime sleepiness in children and academic outcomes

Excessive daytime sleepiness (EDS) in children has been associated with a number of problems. In contrast to adults who experience EDS and who may fall asleep or doze when in a monotonous or boring situation, children with EDS may present as hyperactive or poorly behaved. This community-based study aims to identify the prevalence of EDS in children from three perspectives: parent report, self-report, and teacher report. The study also explores the association between EDS and academic outcomes in children. The participants were 365 students (161 males) aged 4-12 years, their parents, and their teachers at a regional school. Academic outcomes were based on each student's school grades at the conclusion of the semester in which the community-based survey was administered. Using a cutoff score of 15 or greater on the PDSS, 113 (31%) students were identified by at least one respondent as displaying or experiencing EDS. EDS as observed by teachers using the PDSS was found to be associated with the student's academic outcomes, higher sleepiness scores being associated with poorer academic outcomes. Our findings suggest that the prevalence of EDS in a community setting may be higher than previously identified.
