Abstract
OBJECTIVES: To examine the prevalence of different communication- and media-based sedentary behaviors and examine how they are associated with modifiable risk behaviors and key demographic correlates among a large sample of youth. METHODS: Data from 23,031 grade 9 to grade 12 students in Year 1 (2012-2013) of the COMPASS study (Canada) were used to examine the prevalence of sedentary behaviors by gender and by grade. The between-school variance in sedentary behaviors was calculated and models were developed to examine how modifiable risk factors and demographic correlates were associated with sedentary behaviors. RESULTS: Youth averaged 494 (± 313) min/day of sedentary behavior and 96.7% of the sample exceeded the sedentary behavior guidelines of no more than 2h per day. Significant between-school random variation in the sedentary behaviors was identified. Substance use, weight status, ethnicity, and gender were the main predictors of the sedentary behaviors examined. CONCLUSIONS: The vast majority of youth in the COMPASS sample are considered highly sedentary. The evidence clearly suggests we need to develop more effective methods of intervening, that school-based programming is warranted, and that gender-specific programming may be required.
