Adherence
In children and adolescents, high sedentary behavior (specifically TV viewing and screen time) is strongly associated with obesity, and moderately associated with high blood pressure, high cholesterol, and poor academic achievement.
For parents of children, limit recreational screen time. High sedentary time is linked to obesity and poor academic performance. Encourage active play and limit TV/computer use to healthy levels.
GoodSupportsHIGH confidence
Based on the systematic reviews with the best methodological quality, we found in children and adolescents, strong evidence of a relationship between time spent in sedentary behavior and obesity. Moreover, moderate evidence was observed for blood pressure and total cholesterol, self-esteem, social behavior problems, physical fitness and academic achievement.
Why this rating
Based on systematic reviews, though some evidence is cross-sectional.
