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 .
Effect of including parents in a school-based exercise and nutrition program for children.
The purpose of this study was to examine the effect of  parental involvement in a  school-based program about exercise and nutrition .  One fifth grade and one sixth grade class were r and omly assigned to each of the three different treatment conditions , a  school- and -home condition ( n = 45 ) , a  school-only condition  ( n = 43 ) , and a control condition  ( n = 44 ) . In the school- and -home condition , the children 's parents were also asked to participate in nutritional and exercise activities at home as a family " home team . " A multivariate analysis of variance on change scores was completed on the following variables : height , weight , skinfold , sit- and -reach , sit-ups , mile run , exercise knowledge , saturated fat , cholesterol , percent calories from fat , percent calories from carbohydrates , and nutrition knowledge . There was a significant difference among groups . The school- and -home and school-only groups showed significantly greater improvement than the control group but were not significantly different from each other . Univariate analyses on posttest scores indicated that the school- and -home children scored significantly higher than the control group on sit- and -reach flexibility and nutrition knowledge . The results indicate that including the family was primarily effective in facilitating children 's improvements in flexibility and nutrition knowledge rather than in diet and exercise behaviors
