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 .
Effectiveness of a school-based intervention on physical activity for high school students in Brazil: the Saude na Boa project.
BACKGROUND We evaluated the effectiveness of a school-based intervention on the promotion of physical activity among high school students in Brazil : the Saude na Boa project . METHODS A school-based , r and omized trial was carried out in 2 Brazilian cities : Recife ( northeast ) and Florianopolis ( south ) . Ten schools in each city were matched by size and location , and r and omized into intervention or control groups . The intervention included environmental/organizational changes , physical activity education , and personnel training and engagement .  Students age 15 to 24 years were evaluated at baseline and 9 months later ( end of school year ) . RESULTS Although similar at baseline , after the intervention , the control group reported significantly fewer d/wk accumulating 60 minutes+ moderate-to-vigorous physical activity ( MVPA ) in comparison with the intervention group ( 2.6 versus 3.3 , P<.001 ) . The prevalence of inactivity ( 0 days per week ) rose in the control and decreased in the intervention group . The odds ratio for engaging at least once per week in physical activity associated with the intervention was 1.83 ( 95 % CI=1.24 - 2.71 ) in the unadjusted analysis and 1.88 ( 95 % CI=1.27 - 2.79 ) after controlling for gender . CONCLUSION The Saude na Boa intervention was effective at reducing the prevalence of physical inactivity . The possibility of exp and ing the intervention to other locations should be considered
