Objective: This study aimed to investigate the circadian typology of medical students at public universities from one of the northeastern states in Brazil, active in the morning and afternoon shifts, checking the compatibility between their study time, productivity, income and chronotype. Methods: To obtain the results, the assessment of the chronotype in 342 medical students of both sexes was considered. Each participant was submitted to the questionnaire developed by Horne and Ostberg, adapted by Cardinali, Colomberk and Rey. It's composed of 9 questions, providing the general ranking of each individual. Based upon scored, the chronotypes were classified. Results: The sample was composed of 49.12% (168) male and 50.87% (174) female subjects, a similar gender distribution of enrolled students during data collection time. By applying the questionnaire, the prevalent rating among the medical students as moderately morning (29.82%) and intermediate (43.85%) has been relevant. The academic performance assessment in two morning-intermediate groups (8.16) had no significant distance from others considered afternoon active (8.20). Conclusion: The health sciences student, especially Medicine, faces constant adaptation of scheduling, in the attempt of fulfilling the requirements throughout the course, causing chronogram desynchronization effects and forced readaptation to each different school semester.

There are few empirical studies on the teaching of human sexuality in medical curricula, lacking in knowledge of how sexuality is taught, what content is used and how it is offered. The emergence of sexuality for a significant portion of university students occurs in college, which increases the importance of sexual education for this group, even though it constitutes only a small portion of our younger population. This is especially important for health students who should address the issue with their future patients. This research aimed to establish sexual differences between students of both sexes in an entire class of medical students. Evaluating the prevalence of sexual behaviors and sexual dysfunctions in this community was investigated, and finally the sexual patterns of students from a bioethical point of view were analyzed. General and specific questionnaires for both genders were used to evaluate and confront them. As a result, 120 questionnaires were applied in a 3rd year medical class of public universities of a northeastern Brazilian state, representing 100% of the sample. According to the Sexual Exposure Index (SEI), 35% of females predominated in the low risk exposure range. The male gender predominated in the medium exposure range, corresponding to 24.16% of the total target population. Applying the chi-squared test for group B versus A there was a p=8x10-4, X2=15 and OR=1.7. Finally, there is a need to approach this theme in the agenda for inserting it in the curriculum, but more studies are needed to apply this model.
