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 .
Outcomes of a school-based intervention (RESCATE) to improve physical activity patterns in Mexican children aged 8-10 years.
The aim of this study was to evaluate the impact of an intervention program on the patterns of physical activity in 8- to 10-year-old Mexican children from lower socioeconomic status . This study performed a r and omized controlled field trial in 498 children aged 8 - 10 years from 10 public schools of low socioeconomic status in Mexico City . Schools were r and omly assigned to intervention ( n = 5 ) or control ( n = 5 ) groups and followed up during 12 months . Physical and sedentary activities were assessed at the beginning of the program and after 6 and 12 months . At the end of follow-up , there was a significant increase in the performance of moderate physical activity ( MPA ) among children in intervention group who had not performed MPA at baseline any day of the week ( 40 % , P = 0.04 ) but not in the control group ( 8 % , P = not significant ) . The intervention group also showed a significant reduction in the proportion of children who spent more than 3 hours a day playing video games ( from 23 to 13 % , P = 0.01 ) , while control group did not show significant changes . Given these findings , we conclude that intervention was able to modify positively physical activity and reduce time spent on such sedentary activities as video games among those at highest risk studied children
