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 .
Methods and participant characteristics of a randomized intervention to promote physical activity and healthy eating among brazilian high school students: the Saude na Boa project.
BACKGROUND A cross-cultural , r and omized study was proposed to observe the effects of a school-based intervention design ed to promote physical activity and healthy eating among high school students in 2 cities from different regions in Brazil : Recife and Florianopolis . The objective of this article is to describe the methodology and subjects enrolled in the project . METHODS Ten schools from each region were matched and r and omized into intervention and control conditions . A question naire and anthropometry were used to collect data in the first and last month of the 2006 school year . The sample ( n=2155 at baseline ; 55.7 % females ; 49.1 % in the experimental group ) included students 15 to 24 years , attending nighttime classes . The intervention focused on simple environmental/organizational changes , diet and physical activity education , and personnel training . RESULTS The central aspects of the intervention have been implemented in all 10 intervention schools . Problems during the intervention included teachers ' strikes in both sites and lack of involvement of the canteen owners in schools . CONCLUSIONS The Saude na Boa study provides evidence that public high schools in Brazil represent an important environment for health promotion . Its design and simple measurements increase the chances of it being sustained and disseminated to similar schools in Brazil
