Cohort study examines the effect of sleep quality and stress on academic performance in medical students, suggesting important correlations.
Key Points
This research aims to explore how sleep quality and perceived stress influence the academic performance of MBBS students.
Prospective cohort study of 101 first-year MBBS students
Evaluated sleep quality using Pittsburgh Sleep Quality Index and perceived stress with Perceived Stress Scale
Data analysis included paired-samples t-tests, one-way ANOVA, and Pearson’s correlation
Prevalence of poor sleep rose from 38.6% to 47.5% during the pre-examination period
Female students exhibited higher baseline stress levels (21.53 vs. 19.02, p < 0.05) and GPA (1.12 vs. 0.79, p < 0.05)
Negative correlation found between GPA and pre-exam PSQI scores (r = −0.213, p = 0.033) while stress positively correlated with poor sleep (r = 0.348, p < 0.001)
