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 .
Results of an intensive school-based weight loss program with overweight Mexican American children.
Childhood overweight has increased significantly in the past 20 years , with the highest rates noted among Mexican Americans . Schools are an optimal setting for intervention efforts ; however , few programs have demonstrated actual decreases in weight . This study evaluated an intensive school-based program design ed to result in weight reduction for overweight Mexican American children . A total of 71 children ( 32 males , 48 % ) between the ages of 10 and 14 at or above the 85th percentile for body mass index ( BMI ) were r and omized into a six-month intensive intervention ( II ) or self-help ( SH ) condition . Results revealed that children in the II condition significantly reduced their st and ardized BMI ( z BMI ) when compared with the children in the self-help condition ( F(2,62)=6.58 , p=0.003 ) . The change in z BMI was significantly different at both 3 and 6 months ( F(1,63)=5.74 , p=0.019 , F(1,63)=12.61 , p=0.001 , respectively ) with II participants showing greater decreases in weight . The 3-month change in z BMI for the II participants was a decrease of 0.07 compared with a decrease of 0.01 for SH participants . The 6-month change in z BMI was a decrease of 0.11 for II and an increase of 0.03 for SH . Overall , the results are promising , suggesting that an intensive school-based intervention may be an effective means for promoting weight loss in overweight Mexican American children
