Abstract

Background: Sleep plays an important role in students’ physical and mental health and academic performance, especially for medical students who are more susceptible to sleep disorders due to academic pressure, prolonged study hours, and high workload. Objectives: To assess the prevalence and associated factors of sleep quality among medical students from the first to the sixth year at Can Tho University of Medicine and Pharmacy. Materials and methods: A cross-sectional descriptive study was conducted on 1,430 medical students from the first to the sixth year at Can Tho University of Medicine and Pharmacy. Data were collected using a structured questionnaire, including general information, the Pittsburgh Sleep Quality Index (PSQI), and the Depression Anxiety Stress Scale-21 (DASS-21). Data were analyzed using SPSS 25.0 with appropriate statistical tests. Results: The percentage of students at risk of sleep disorders was 52.8%, with an average PSQI score of 6.21 ± 3.22, which tended to increase with academic year, being highest in the last three years of the program (p<0.01). There were statistically significant positive correlations between PSQI scores and DASS-21 scores, specifically for stress (r=0.414; p<0.001), anxiety (r=0.408; p<0.001), and depression (r=0.388; p<0.001). These three factors combined accounted for 18.6% of the variance in PSQI scores. Conclusion: The percentage of medical students at Can Tho University of Medicine and Pharmacy at risk of sleep disorders was 52.8%, which varied by year of the program. Depression, anxiety, and stress factors on the DASS-21 scale were positively correlated with the risk of sleep disorders on the PSQI scale.
