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 .
Short-term effects of school-based weight gain prevention among adolescents.
OBJECTIVE To determine whether a multicomponent health promotion intervention for Dutch adolescents would be successful in influencing body composition and aerobic fitness . DESIGN R and omized controlled trial . SETTING Ten intervention and 8 control prevocational secondary schools . PARTICIPANTS A total of 978 adolescents ( mean age , 12.7 years ) . INTERVENTION An interdisciplinary multicomponent intervention program with an adapted curriculum for 11 biology and physical education lessons and environmental change options , including additional lessons on physical education and advice on the school canteen selection . MAIN OUTCOME MEASURES Body height and weight , hip and waist circumference , 4 skinfold thickness measurements , and aerobic fitness . RESULTS Multilevel analyses showed significant differences in changes after the 8-month intervention period in favor of the intervention group with regard to hip circumference ( mean difference , 0.53 cm ; 95 % confidence interval , 0.07 to 0.98 ) and sum of skinfolds among girls ( mean difference , -2.31 mm ; 95 % confidence interval , -4.34 to -0.28 ) . In boys , the intervention result ed in a significant difference in waist circumference ( mean difference , -0.57 cm ; 95 % confidence interval , -1.10 to -0.05 ) . No significant intervention effects were found related to aerobic fitness . CONCLUSIONS The multicomponent Dutch Obesity Intervention in Teenagers program positively influenced several measures of body composition among both girls and boys . Our results indicate that secondary prevocational school curriculum changes may contribute to excessive weight gain prevention among adolescents
