Objectives: To investigate the association between sedentary behavior and sleep variables (daytime sleepiness and sleep duration) of adolescents in a small city in the south of Brazil. Methods: This is a representative school-based sample in the city of Maravilha, SC, Brazil, composed of 516 adolescents of both sexes, from 10 to 19 years old. Associations were investigated among sedentary behaviors, sleep, perception of stress and physical activity. Sedentary behavior was investigated by mean of sitting time during the day. In addition, other issues were investigated as sex, age, school shift, place of residence, income, and level of education of household head, sleep duration, and daytime sleepiness, perception of stress and level of physical activity. Results: The prevalence of short sleep duration was 53.6%. The average time sitting during a weekday was 382.2 min, being higher in females (p = 0.001). Adolescents with short sleep duration had higher average values of sitting time (p<0.001), daytime sleepiness (p<0.001) and sleepiness in classroom (p<0.001). Adolescents with highest sleepiness were 4.97 (CI: 2.50 to 9.87) times more likely to have high sedentary behavior. Conclusion: Adolescents with higher daytime sleepiness showed greater time spent on sedentary behaviors. Thus, the education measures for a more active lifestyle during adolescence should also observe general questions about sleep and daytime sleepiness.
