A recent study focused on the relationship between sleep quality, particularly insomnia, and academic performance among high school students in Vietnam. A total of 639 students from both urban Hanoi and rural Hung Yen participated, leading to an analysis of 541 students due to the absence of missing data. The study utilized self-report questionnaires to assess sleep quality, insomnia symptoms, academic performance, motivation, and fatigue.

Results from canonical correlation analyses indicated a significant correlation (r = 0.20, p < 0.05) between insomnia symptoms and lower academic performance. Specifically, sleep quality factors such as Sleep Duration, Day Dysfunction, and Medication Use exhibited unique statistical relationships with academic performance. The academic performance metric primarily reported by students was their GPA. When motivation and fatigue were included in the analysis as covariates, the strength of the relationship diminished significantly, suggesting these factors might act as mediators between insomnia and academic outcomes.
The study highlighted that insomnia is prevalent among adolescents, with estimates suggesting rates as high as 25%. Among the Pw participants, the associations between insomnia components like Day Dysfunction showed variability depending on the students' grade levels but were unaffected by gender.
In conclusion, the findings suggest potential interventions, such as Sleep Extension Therapy targeting increased sleep duration, could enhance academic performance. Future longitudinal studies are needed to explore these relationships further, particularly in understanding the impact of different insomnia components on cognitive functions essential for academic success.
