Abstract
Objective: To describe the quality of sleep of medical students at na university in Teresina-PI and correlate it with epidemiological data. Methods: The study is a cross-sectional analytical type, carried out through an online self-administered questionnaire containing the validated Pittsburgh Sleep Quality Index (PSQI), in addition to additional socio-demographic data. Results: The sample consisted of 151 students. According to the PSQI, 79.48% (n = 120) of the participants had poor quality sleep patterns. There was statistical significance only between poor quality sleep and medication use (p <0.05). Conclusion: It is clear that, despite the extensive literature covering the quality of sleep in this population, little is done to combat this serious problem. The poor quality of sleep continues to be neglected, mainly by the students themselves, who do not recognize themselves as a population of risk and do not seek, in most cases, the correction of harmful habits or attitudes that compromise their quality of sleep.
