Introduction: Prolonged use of electronic devices has increased significantly among university students.
Objective: To evaluate the impact of screen time on academic performance, stress, and sleep quality.
Methodology: Explanatory, non-experimental, correlational study in third-semester medical students. A 20-item questionnaire was administered, which included the Perceived Stress Scale-10. The analysis was performed using SPSS and Excel, using Pearson's correlation and ANOVA.
Results: Cell phones were the most commonly used screens, with ranges from 7 to 10 hours per day. No significant relationship was observed between screen time and academic performance. A moderate negative correlation was identified between stress and sleep quality.
Conclusion: Screen time did not show a significant direct impact on academic performance, although stress was negatively associated with sleep quality.
