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.
