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 .
Action Schools! BC: a school-based physical activity intervention designed to decrease cardiovascular disease risk factors in children.
OBJECTIVE Our primary objective was to determine whether a novel ' active school ' model -- Action Schools ! BC -- improved the cardiovascular disease ( CVD ) risk profile in elementary-school children . Our secondary objective was to determine the percentage of children with elevated CVD risk factors . METHODS We undertook a cluster-r and omized controlled school-based trial with 8 elementary schools across 1 school year , in British Columbia , Canada , beginning in 2003 . Boys and girls ( n=268 , age 9 - 11 years ) were r and omly assigned ( by school ) to usual practice ( UP , 2 schools ) or intervention ( INT , 6 schools ) groups . We assessed change between groups in cardiovascular fitness ( 20-m Shuttle Run ) , blood pressure ( BP ) , and body mass index ( BMI , wt/ht(2 ) ) . We evaluated total cholesterol ( TC ) , total : high-density cholesterol ( TC : HDL-C ) , low-density lipoprotein , apolipoprotein B , C-reactive protein and fibrinogen on a subset of volunteers ( n=77 ) . RESULTS INT children had a 20 % greater increase in fitness and a 5.7 % smaller increase in BP compared with children attending UP schools ( P<0.05 ) . Forty five percent of children had at least one elevated risk factor ( fitness , BP or BMI ) at baseline . There were no significant differences between groups for change in BMI or in any of the blood variables . CONCLUSION Action Schools ! BC was an effective school-based physical activity model for improving the CVD risk profile of elementary-school children . Our multi-component intervention exposed children to fitness enhancing physical activity . It may be important for education stakeholders to adequately re source the delivery of the active school models if cardiovascular health benefits are to be achieved on a population basis
