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 .
PRALIMAP: study protocol for a high school-based, factorial cluster randomised interventional trial of three overweight and obesity prevention strategies
Background Given the increase in overweight and obesity prevalence in adolescents in the last decade , effective prevention strategies for these conditions in adolescents are urgently needed . The PRALIMAP ( Promotion de l'ALImentation et de l'Activité Physique ) trial aims to evaluate the effectiveness for these conditions of 3 health promotion strategies -- educational , screening and environmental -- applied singly or in combination in high schools over a 2-year intervention period . Methods PRALIMAP is a stratified 2 × 2 × 2 factorial cluster r and omised controlled trial including 24 state high schools in Lorraine , northeastern France , in 2 waves : 8 schools in 2006 ( wave 1 ) and 16 in 2007 ( wave 2 ) . Students entering the selected high schools in the 4 academic years from 2006 to 2009 are eligible for data collection . Interventional strategies are organized over 2 academic years . The follow-up consists of 3 visits : at the entry of grade 10 ( T0 ) , grade 11 ( T1 ) and grade 12 ( T2 ) . At T0 , 5,458 ( 85.7 % ) adolescents participated . The educational strategy consists of nutritional lessons , working groups and a final party . The screening strategy consists in detecting overweight/obesity and eating disorders in adolescents and proposing , if necessary , an adapted care management program of 7 group educational sessions . The environmental strategy consists in improving dietary and physical activity offerings in high schools and facilities , especially catering . The main outcomes are body size evolution over time , nutritional behaviour and knowledge , health and quality of life . An evaluation process documents how each intervention strategy is implemented in the schools and estimates the dose of the intervention , allowing for a per protocol analysis after the main intention-to-treat analysis . Discussion PRALIMAP aims at improving the prevention and management of overweight and obesity in adolescents by translating current evidence into public health practice . Particular attention is paid to clustering , multiple factorials and long-term duration to address common pitfalls in health promotion trials . The results should inform how best to implement , in a school environment , effective nutrition prevention programs targeting adolescents who are at a point their lives when they develop responsibilities and empowerment for health attitude behaviours .
