Objective: This study aimed to investigate the relationship between sleep quality and the general degree of academic achievement in school students.
Methods: A cross-sectional, school-based study was conducted including elementary, intermediate, and secondary school students. The study used a standardized, confidential, validated self-administered questionnaire to assess sleep quality and habits, socio-demographic data, and the Epworth sleepiness scale for daytime sleepiness. The main outcome of the measure was the achievement of students.
Results: A total of 957 participants were included in the study. Achievement of the students was significantly related to the following parameters including laziness and fatigue after wake-up time, laziness and fatigue during school time, lack of concentration during school time, difficulty in completing tasks during school time, and inability to maintain wakefulness during school time. Furthermore, students with poor academic degrees reported more significant incidents of sleeping at school, paralysis, loss of ability to talk during and after sleep, snoring, restless syndrome, and excessive daytime sleepiness.
Conclusion: Students with poor sleep quality had lower school grades.
