Abstract
Objective: This study aims to determine the prevalence and the association of stress with sleep quality among medical students at King Abdulaziz University (KAU), Jeddah, Saudi Arabia. Methods: A cross-sectional study was done among 326 medical students of KAU using a stratified random sampling technique. An electronic self-administered questionnaire was used. Kessler Psychological Distress Scale (K10) and Pittsburgh Sleep Quality Index (PSQI) were used to assess the stress and sleep quality, respectively. Results: The overall students who experienced stress were 65%. The prevalence of poor sleep quality (total PSQI score >= 5) was 76.4%. There was a strong association between stress and poor sleep quality (value of Cramer's V = 0.371, P < 0.001), and it showed that the increase in stress level is a significant predictor of poor sleep quality. Conclusion: A high prevalence of stress and poor sleep quality was found among the students and the study confirms a strong association between them. We recommend establishing courses focusing on educating the students about proper sleep hygiene and how to deal with the stressful environment.
