ASSOCIATE FACTORS WITH SLEEP DURATION AND SOCIAL LAG IN UNIVERSITY STUDENTS IN THE COUNTRYSIDE OF RIO GRANDE DO NORTE: STUDY BASED ON SOCIAL HEALTH DETERMINANTS
Sleep-wake cycle; Structural Determinants of Health; Intermadiate Determinants of Health; Jetlag Social.
In the last decade, the growth of higher education in countryside has led to the migration of students from neighboring municipalities to a university city, and this displacement may generate a change in lifestyle. Among these changes, sleep deprivation and different schedules sleep anda wake up times between free days and work / study days, which characterize social lag, are increasingly observed in society, being prevalent in university students. Therefore, the aim of this study was to analyze which factors of Social Determinants of Health are associated with sleep duration and social lag in university students in the countryside of Rio Grande do Norte (RN). Developed with students from the Faculty of Health Sciences of Trairi, located in Santa Cruz-RN, through the application of 02 questionnaires: “Health and sleep” and the Munich chronotype questionnaire. Pearson's correlation coefficient was used to analyze the association of variables independently to outcomes, sleep duration during the week and weekend, and social lag. Independent variables with significant association (p <0.20) in the correlation test were included in the multivariate model. Multiple linear regression with stepwise foward method was used, with variables that showed a statistically significant correlation with the analyzed outcome remaining in the final model (p <0.05). Sleep duration in the week of less than 6h was prevalent in 43% of the sample (6h39min ± 1h28min) while at the weekend, 92.3% had sleep duration greater than 6h (8h01min ± 1h32min). Regarding social lag (1h21min ± 55min), 34.2% of the participants had social lag <1 hour, 52.3% had social lag between 1 and 2 hours and 13.4% had> 2 hours. There was no association between structural health determinants and the variables sleep duration in the week, sleep duration at the weekend and social lag. Regarding the intermediate determinants of health, the predictive variables for the duration of sleep in the week: chronotype (B = -0.55), sex (B = - 24.78), leisure activities (B = -27.94), sleeping place (B = -42.78) and housing (B = 24.95). For the duration of sleep over the weekend: sex (B = -36.36), chronotype (B = 0.24), sleeping place (B = -58.15), recreational and religious activities (B = -31 , 11), leisure activities (B = -25.10) and academic demand (B = -23.60). For Social lag were: leisure activities (B = 23.24), academic demand (B = 19.51), household chores (B = 17.61) and stimulating drinks (B = -15.17).Therefore, university students in the countryside of RN had shorter sleep duration on school days and longer duration on free days, and more than half of the sample had social lag. Regarding the intermediate determinants of health, there was an association of the outcomes with the biological, behavioral factors and with the students' living conditions. It is important to note that this is an unprecedented study carried out with students from the countryside of the state. Therefore, these discussions help both in the university context and in public health, and can expand the knowledge of how DSS impact sleep health. Considering that these university students will be future health professionals, the results of this study can serve as a basis for expanding the discussion and dissemination of knowledge about sleep hygiene in order to contribute to the learning process of these future health professionals.
