Purpose. Sedentary behavior has been identified as a risk factor for chronic non-communicable diseases. This study identified the prevalence of excessive TV viewing time during the week and weekend and associated factors in adolescents living in a small urban and rural area. Methods. A cross-sectional study involving 283 students (aged 10-19 years) from Brazil was conducted in 2010. Data on TV viewing time and sociodemographic information were collected by questionnaires, cardiorespiratory fitness was evaluated by the 20-m shuttle run test, and anthropometric characteristics were obtained by measuring waist circumference and skinfold thickness. Statistical analysis involved binary logistic regression. Results. The prevalence of excessive TV viewing time ( 2 h) was 76.7% during on weekdays and 78.4% on the weekend. Adolescents aged 10-12 years (OR = 6.20; 95% CI = 2.91, 13.19; p < 0.001) and 13-15 years (OR = 2.57; 95% CI = 1.28, 5.18; p = 0.008) were more exposed to excessive TV viewing time during the week. No associations were found for excessive TV viewing time on the weekend. Conclusions. Approximately 8 in 10 adolescents presented excessive TV viewing time; excessive TV viewing time during the week was associated with age.
