No correlation was found between cumulative grades (GPA), sleep quality, chronotype, body mass index, and sleep duration during weekdays and weekends (p>0.005), the females medical students had good sleep quality and lower body mass index, were more likely morning chronotype, and had higher GPA compared to males.
