 This systematic review examines the relationship between sedentary behavior and health indicators in school-aged children and youth aged 5 to 17 years. The study found that increased sedentary behavior was associated with unfavorable health outcomes, including body composition, fitness, self-esteem, prosocial behavior, and academic achievement. Watching TV for more than two hours per day was particularly associated with these negative outcomes. A meta-analysis of randomized controlled studies revealed an overall significant effect of decreasing sedentary time on mean BMI, indicating that reducing any type of sedentary time is associated with lower health risk in youth aged 5 to 17 years. The evidence suggests that daily TV viewing in excess of two hours is associated with reduced physical and psychosocial health, and that lowering sedentary time leads to reductions in BMI.
