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 .
The impact of the Pathways intervention on psychosocial variables related to diet and physical activity in American Indian schoolchildren.
BACKGROUND The purpose of this study was to examine the impact of the Pathways intervention on pychosocial variables related to physical activity and diet in American Indian children . METHODS Schools serving American Indian children were r and omized to a multicomponent intervention or control condition . At baseline ( fall of third grade ) and in the spring semester of third , fourth , and fifth grade s 755 boys and 692 girls completed a classroom-administered question naire . The question naire assessed self-efficacy , knowledge , and behavioral intentions related to diet and physical activity , as well as weight loss behaviors and body image . RESULTS Knowledge of nutrition and physical activity messages increased in both boys and girls in the intervention group compared to controls ; however , knowledge of which foods contained more fat did not increase consistently . Compared to controls , self-efficacy to be physically active increased among girls in intervention schools , but not among boys , whereas self-efficacy to make more healthy food choices did not increase more than in controls in either gender . In the intervention group , compared to controls , healthy food intentions and participation in physically active behaviors increased in both boys and girls . Perception of healthy body size and weight loss attempts did not differ in the intervention and control groups . CONCLUSION The Pathways intervention program had a positive impact on several aspects of obesity-related knowledge , attitudes , and behaviors
