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 .
A primary-school-based study to reduce prevalence of childhood obesity in Catalunya (Spain) - EDAL-Educació en alimentació: study protocol for a randomised controlled trial
Background The EdAL ( Educació enAlimentació ) study is a long-term , nutrition educational , primary -school-based program design ed to prevent obesity by promoting a healthy lifestyle that includes dietary recommendations and physical activity . The aims are : 1 ) to evaluate the effects of a 3-year school-based life-style improvement program on the prevalence  of obesity in an area of north-west Mediterranean 2 ) To design a health-promotion program to be implemented by health-promoter agents ( university students ) in primary schools . Methods / Design 1 ) The intervention study is a r and omised , controlled , school-based program performed by  university-student health-promoter agents . Initial pupil enrolment was in 2006 and continued for 3 years . We considered two clusters ( design ated as cluster A and cluster B ) as the units for r and omisation . The first cluster involved 24 schools from Reus and the second involved 14 schools from surrounding towns Cambrils , Salou and Vilaseca combined in order to obtain comparable groups . There are very good communications between schools in each town , and to avoid cross influence of the programs result ing from inter-school dialogue , the towns themselves were the unit for r and omisation . Data collected included name , gender , date and place of birth at the start of the program and , subsequently , weight , height , body mass index ( BMI ) and waist circumference every year for 3 years . Question naires on eating and physical activity habits are filled-in by the parents at the start and end of the study and , providing that informed consent is given , the data are analysed on the intention-to-treat basis . The interventions are based on 8 nutritional and physical activity objectives . They are implemented by university students as part of the university curriculum in training health-promoter agents . These 8 objectives are developed in 4 educational activities/year for 3 years ( a total of 12 activities ; 1 h/activity ) performed by the health-promoter agents in primary schools . Control pupils follow their usual activities.2 ) Courses on education and promotion of health , within in the curriculum of medicine and health sciences for university students , are design ed to train health-promoter agents to administer these activities in primary schools . Discussion This controlled school-based intervention will test the possibility of preventing childhood obesity . Trial registration numberIS RCT N : IS RCT
