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 .
Reducing overweight through a multidisciplinary school-based intervention.
OBJECTIVE This study sought to evaluate the effectiveness of a multidisciplinary elementary school-based intervention entitled Wellness , Academics & You . The primary areas of impact examined were BMI , consumption of fruits and vegetables , and physical activity . RESEARCH METHODS AND PROCEDURES The sample consisted of 1013 students in fourth and fifth grade s from 69 classes in four states .  Intervention and comparison classes were r and omly selected at each school . Intervention teachers participated in workshops on the intervention and received program material s.  BMI was calculated for baseline and post- data points based on measured height and weight collected by trained research teams . Baseline surveys were administered by the students ' teacher in the presence of one of the research team members and collected . RESULTS SPSS ( SPSS , Inc. , Chicago , IL ) analysis of post- data shows significant positive shifts ( p = 0.01 ) in BMI in the intervention group compared with the comparison group . Notable increases in the consumption of fruits and vegetables and increased physical activity levels were reported in the intervention group . DISCUSSION Data from this study indicate that this school-based program may contribute to the reduction of overweight and obesity . The intervention was well received by the classroom teachers and shows promise for a school-based obesity prevention initiative . This program has shown the capacity to effect positive changes in BMI through consumption of fruits and vegetables and physical activity . The evaluation covered a limited time period and , therefore , warrants additional studies to determine whether long-term program fidelity will result in continued improvement
