Abstract
Objective: To evaluate the sleeping quality and the excessive daytime sleepiness degree in medical
students at a university center in the state of Pará. Methods: This is a descriptive cross-sectional study,
conducted with 192 medical students attending the first the four years of graduation, investigated through
questionnaires: Pittsburgh Sleeping Quality Index (PSQI), Epworth Sleepiness Scale (ESE) and
sociodemographic. Analytical statistics were performed using the G and Chi-Square Tests in the BioEstat 5.5
program. Results: There was a predominance of low sleeping quality, with 29.7% of patients with sleeping
disorders. Over the years, the proportion of poor sleeping has increased. The ESE indicated absence of
sleepiness over most students, with an increase in the proportion of absence of sleepiness over the years. It
is pointed out that this discrepancy may be related to the increased consumption of stimulating substances
assessed by the study. There was no significance regarding gender and marital status differences.
Conclusion: There was a significant incidence of students with poor sleeping quality, including those with
sleeping disorders. In contrast, the study showed excessive daytime sleepiness in the minority of students.
