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 .
Design and evaluation protocol of "FATaintPHAT", a computer-tailored intervention to prevent excessive weight gain in adolescents
Background Computer tailoring may be a promising technique for prevention of overweight in adolescents . However , very few well-developed , evidence -based computer-tailored interventions are available for this target group . We developed and evaluated a computer-tailored intervention for adolescents targeting energy balance-related behaviours : i.e. consumption of snacks , sugar-sweetened beverages , fruit , vegetables , and fibre , physical activity , and sedentary behaviours . This paper describes the planned development of a school-based computer-tailored intervention aim ed at improving energy balance-related behaviours in order to prevent excessive weight gain in adolescents , and the protocol for evaluating this intervention . Methods / design Intervention development : Informed by the Pre caution Adoption Process Model and the Theory of Planned Behaviour , the computer-tailored intervention provided feedback on personal behaviour and suggestions on how to modify it . The intervention ( VETisnietVET translated as ' FATaintPHAT ' ) has been developed for use in the first year of secondary school during eight lessons . Evaluation design : The intervention will be evaluated in a cluster-r and omised trial including 20 schools with a 4-months and a 2-years follow-up . Outcome measures are BMI , waist circumference , energy balance-related behaviours , and potential determinants of these behaviours . Process measures are appreciation of and satisfaction with the program , exposure to the program 's content , and implementation facilitators and barriers measured among students and teachers . Discussion This project result ed in a theory and evidence -based intervention that can be implemented in a school setting . A large-scale r and omised controlled trial with a short and long-term follow-up will provide sound statements about the effectiveness of this computer-tailored intervention in adolescents .
