There was some evidence that school-based physical activity interventions had a positive impact on four of the nine outcome measures .
Specifically positive effects were observed for duration of physical activity , television viewing , VO2 max , and blood cholesterol .
Generally , school-based interventions had little effect on physical activity rates , systolic and diastolic blood pressure , BMI , and pulse rate .
At a minimum , a combination of printed educational material s and changes to the school curriculum that promote physical activity result ed in positive effects .
Few changes in outcomes were observed in this up date with the exception of blood cholesterol and physical activity rates .
For example blood cholesterol was no longer positively impacted upon by school-based physical activity interventions .
The evidence suggests the ongoing implementation of school-based physical activity interventions at this time , given the positive effects on behavior and one physical health status measure .
BACKGROUND The World Health Organization ( WHO ) estimates that 1.9 million deaths worldwide are attributable to physical inactivity and at least 2.6 million deaths are a result of being overweight or obese .
In addition , WHO estimates that physical inactivity causes 10 % to 16 % of cases each of breast cancer , colon , and rectal cancers as well as type 2 diabetes , and 22 % of coronary heart disease and the burden of these and other chronic diseases has rapidly increased in recent decades .
OBJECTIVES The purpose of this systematic review was to summarize the evidence of the effectiveness of school-based interventions in promoting physical activity and fitness in children and adolescents .
Kids and adults now! Defeat Obesity (KAN-DO): rationale, design and baseline characteristics.
BACKGROUND Prevention of childhood obesity is a public health priority . Parents influence a child 's weight by modeling healthy behaviors , controlling food availability and activity opportunities , and appropriate feeding practice s. Thus interventions should target education and behavioral change in the parent , and positive , mutually reinforcing behaviors within the family . METHODS This paper presents the design , rationale and baseline characteristics of Kids and Adults Now ! - Defeat Obesity ( KAN-DO ) , a r and omized controlled behavioral intervention trial targeting weight maintenance in children of healthy weight , and weight reduction in overweight children . 400 children aged 2 - 5 and their overweight or obese mothers in the Triangle and Triad regions of North Carolina are r and omized equally to control or the KAN-DO intervention , consisting of mailed family kits encouraging healthy lifestyle change . Eight ( monthly ) kits are supported by motivational counseling calls and a single group session . Mothers are targeted during a hypothesized " teachable moment " for health behavior change ( the birth of a new baby ) , and intervention content addresses : parenting skills ( ( e.g. , emotional regulation , authoritative parenting ) , healthy eating , and physical activity . RESULTS The 400 mother-child dyads r and omized to trial are 75 % white and 22 % black ; 19 % have a household income of $ 30,000 or below . At baseline , 15 % of children are overweight ( 85th-95th percentile for body mass index ) and 9 % are obese ( ≥ 95th percentile ) . CONCLUSION This intervention addresses childhood obesity prevention by using a family-based , synergistic approach , targeting at-risk children and their mothers during key transitional periods , and enhancing maternal self-regulation and responsive parenting as a foundation for health behavior change
