Well-being, cognition and health status assessment in college students and general population of Sao Paulo, according to chronotype and presence of sleep disorders

Coordinator: Prof. Dr. Dalva Lucia Rollemberg Poyares


Wake / Sleep Cycle and Sleep Disorders are common among young people and can greatly affect overall performance. Sleep and wakefulness play an important role in students’ performance. The maintenance of the biological rhythmicity is preponderant for the proper functioning of the organism, and changes in its synchronization and / or timing have been related to the development of metabolic disorders, mood disorders, increase in the incidence of tumors, among other changes in the physiology of the human organism. Respect for individual biological rhythmicity (expressed by chronotype) has also proved important for more effective initiatives in the field of education and cognition, such as changes in the school period showing that the later onset in the morning has is a more adequate alternative for adolescents, in particular (with potential to be applied for all age groups), with a significant improvement in learning scores and school social interaction. In this sense, the evaluation and implementation of strategies that propose better adaptation of students according to their chronotype are welcome in the current context. The recent Nobel Prize in Medicine, 2017 was awarded to scientists who revealed the molecular mechanisms controlling biological rhythmicity, recognizing the importance that the preservation of rhythms and their synchronization to the environment plays a critical role in the overall functioning and performance of the organism. Given that our University has professors and researchers with experience in this area of knowledge, and that the applicability of discoveries and studies of circadian rhythms have important implications on health, well-being, cognition and learning, we also propose to evaluate the patterns of wakefulness and sleep disturbances in students and in the general population of São Paulo. However, other sleep disorders unrelated to the wake / sleep rhythm are prevalent and significantly affect the acquisition and learning process in a complex way. Several studies are proposed and others are already being carried out aiming to evaluate physiological, diagnostic and therapeutic aspects of sleep and its disorders in special populations and in the general population. These protocols will be conducted jointly by 3 of the participating PGPs.
