| Resumo: | INTRODUCTION: The irregularity in sleep/wake cycle between free days and work/study
days, which called social lag, added the reduction in sleep duration during the week are habits
that are increasingly observed in university students. In the last decade in Brazil, there was a
process of migration of students to a university city due to the growth of higher education in
less urbanized cities, which can generate changes in lifestyle and in the sleep habits of these
students. The study of how the social environment can impact on the health of the individuals
can be carried out based on models of social determinants of health, which can be of a structural
or intermediate nature. The first is related to socioeconomic positions, education and work
issues and the second is related to behavioral influences at the individual level. In view of this,
the aim of this study was to analyze which factors of the Social Determinants of Health are
associated with the duration of sleep and social lag in university students in the country city of
Rio Grande do Norte (RN). METHODS: Developed with university students from the Faculty
of Health Sciences of Trairi, located in Santa Cruz-RN, through the application of two
questionnaires: “Health and sleep” and the “Munich chronotype questionnaire”. To analyze the
association between the independent variables and the sleep duration outcomes at week and
weekend, and social lag, multiple linear regression was adopted with stepwise forward method.
The level of significance adopted was 5%. RESULTS: There was no association between the
determinants of health (socioeconomic class, work, knowledge about sleep and the start time of
classes) with variables sleep duration in the week and weekend, and social lag. Regarding the
intermediate determinants of health, the predictive variables for the duration of sleep during the
week were chronotype (β = -0.55, p = 0.001), gender (β = - 24.78, p = 0.008), leisure activities
(β = -27.94; p = 0.003), sleeping place (β = -42.78; p = 0.005) and housing (β = 24.95; p =
0.010). For the duration of sleep over the weekend were gender (β = -36.36; p = 0.001),
chronotype (β = 0.24; p = 0.001), sleeping place (β = -58.15; p = 0.001), recreational and
religious activities (β = -31.11; p = 0.027), leisure activities (β = -25.10; p = 0.021) and
academic demand (β = -23.60; p = 0.025). The predictive variables of social lag were leisure
activities (β = 23.24), academic demand (β = 19.51), household chores (β = 17.61) and
stimulating drinks (β = -15.17). In addition, it was observed that 43% of the sample had a sleep
duration in the week less than 6h (average = 6h39min ± 1h28min), while 92.3% had sleep
duration of more than 6h (average = 8h01min ± 1h32min). The average social lag was 1h21min
± 55min. 34.2% of the participants had social lag less than 1h, 52.3% had social lag between
1h and 2h and 13.4% had social lag greater than 2h. CONCLUSION: The observed associations
were related to the intermediate determinants of health classified as biological, behavioral and
housing conditions of university students. University students from the interior of RN had
shorter sleep duration on school days and longer duration on free days, and 65.7% of the sample
had social lag greater than 1h. This study carried out with students from the country city of the
state of Rio Grande do Norte is a pioneer study and may contribute to the discussions related to
the university context. In addition, considering that these university students will be future
health professionals, the results can serve as a basis for discussing the impact of social
determinants of health on sleep/wake cycle of individuals and discussing sleep hygiene in the
public health context. |
