There is a large body of evidence from all study design s which suggests that decreasing any type of sedentary time is associated with lower health risk in youth aged 5 - 17 years .
In particular , the evidence suggests that daily TV viewing in excess of 2 hours is associated with reduced physical and psychosocial health , and that lowering sedentary time leads to reductions in BMI
Accumulating evidence suggests that , independent of physical activity levels , sedentary behaviours are associated with increased risk of cardio-metabolic disease , all-cause mortality , and a variety of physiological and psychological problems .
Therefore , the purpose of this systematic review is to determine the relationship between sedentary behaviour and health indicators in school-aged children and youth aged 5 - 17 years .
The effect of reinforcement or stimulus control to reduce sedentary behavior in the treatment of pediatric obesity.
Obese children were r and omly assigned to a family-based behavioral treatment that included either stimulus control or reinforcement to reduce sedentary behaviors . Significant and equivalent decreases in sedentary behavior and high energy density foods , increases in physical activity and fruits and vegetables , and decreases in st and ardized body mass index ( z- BMI ) were observed . Children who substituted active for sedentary behaviors had significantly greater z- BMI changes at 6 ( -1.21 vs. -0.76 ) and 12 ( -1.05 vs. -0.51 ) months , respectively . Substitution of physically active for sedentary behaviors and changes in activity level predicted 6- and 12-month z- BMI changes . Results suggest stimulus control and reinforcing reduced sedentary behaviors are equivalent ways to decrease sedentary behaviors , and behavioral economic relationships in eating and activity may mediate the effects of treatment
