Sleep quality of working and physically inactive adolescents

Abstract

Introduction: Sleep is a physiological need that restores the physical and psychological conditions worn during the waking state. A good sleep quality is directly linked to the healthy development, especially for adolescents. Objective: This study aimed to analyze the associations between sleep quality with occupational status and physical activity of adolescents from Amazonas. Method: This is a cross-sectional, school-based epidemiological study conducted with 2,517 adolescents (1,411 girls and 1,106 boys) with a mean age of 16.6 (SD = 1.2) years, from public schools in Amazonas. The adolescents answered a self-administered questionnaire containing information on sleep quality (dependent variable), gender, age group, scholar shift, family income, occupational status and physical activity. The association between the exploratory variables and the sleep quality was verified by means of binary logistic regression. The analysis was adjusted by all variables, including sociodemographic variables. Results: The prevalence of low sleep quality was 20.3%. Working adolescents were 69.0% more likely to have poor sleep quality, and those who were physically inactive had a 66.0% chance when compared to their respective peers who did not work and were physically active. Conclusion: Two out of ten adolescents presented poor sleep quality. The development of feasible interventions and public policies aimed at improving the sleep quality in adolescents should consider the occupational activities and physical inactivity.
