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 .
Effects of decreasing sedentary behavior and increasing activity on weight change in obese children.
Obese children 8 - 12 years old from 61 families were r and omized to treatment groups that targeted increased exercise , decreased sedentary behaviors , or both ( combined group ) to test the influence of reinforcing children to be more active or less sedentary on child weight change . Significant decreases in percentage overweight were observed after 4 months between the sedentary and the exercise groups ( -19.9 vs. -13.2 ) . At 1 year , the sedentary group had a greater decrease in percentage overweight than did the combined and the exercise groups ( -18.7 vs. -10.3 and -8.7 ) and greater decrease in percentage of body fat ( -4.7 vs. -1.3 ) . All groups improved fitness during treatment and follow-up . Children in the sedentary group increased their liking for high-intensity activity and reported lower caloric intake than did children in the exercise group . These results support the goal of reducing time spent in sedentary activities to improve weight loss
