The influence of ethanol and coffee on medical students’ sleep quality

Abstract

Introduction: The comsuption of ethanol and coffee may be retracted as a sleep disruptor principally in medical students and this can compromise their welfare and daily activities. Objectives: The purpose of this study was to evaluate sleep quality and your possible correlation between comsuption of ethanol and caffeine in medical students of Faculdade de Medicina de Jundiaí. Methodology: This is a cross-sectional study with 143 medical students that answered specific questionnaires about sleep quality (Pittsburg Sleep Quality Index), alcohol comsuption (AUDIT) and caffeine comsuption. Chi-square tests and multivariate logistic regression models were used to identify statistically significant association between these variables. Results: The results showed that the prevalence of poor sleep quality (PSQI > 5 points) was found to be 65,7%; 71,3% had low risk comsuption of ethanol. There was a weak correlation (R = 0.251), however statistically significant (p = 0.020) only between sleep quality and ethanol comsuption. Conclusion: These results designate the necessity of projects and wariness to aim for promotion of medical student’s quality of life.
