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 .
A school-based intervention to teach third grade children about the prevention of heart disease.
Coronary heart disease continues to be a leading cause of death in adults . Because many risk factors for heart disease make their first appearance in childhood , early intervention is an attractive strategy for this disease . A convenience sample of 58 third grade children participated in a year-long , quasi-experimental study to compare a school-based educational program , HeartPower ! , to the st and ard health education curriculum . Variables examined included knowledge , hypercholesterolemia , obesity , sedentary lifestyle , hypertension , exposure to cigarette smoke , and parental participation . The students who participated in the HeartPower ! Program showed improvement ( p < 0.05 ) in their knowledge of healthy lifestyles . Modest improvements in hypertension and exposure to tobacco smoke were observed . These results indicate that focused instruction on important health issues may be preferable to a broad approach
