Prevention of overweight in the school arena

This paper gives an overview of studies with the main purpose to intervene against obesity in children at the school arena. Through databases and Cochrane reviews, 14 studies fulfilled the criteria for inclusion. Most of the studies are American and none were performed in Scandinavia. The European studies were performed in Germany and in the United Kingdom. The studies, which had a significant effect on overweight were 'Dance for Health', 'Planet Health', 'San Jose Study', 'Kiel Obesity Prevention Study', 'Healthy Schools' programme, 'El Paso Catch', and 'Medical College of Georgia FitKid Project'. The studies differ greatly in regards to age group, type of and length of intervention and type and amount of actions. Furthermore, the measures used to evaluate the effect differed. It seems to be important to use several measures of obesity in order to accurately detect a possible effect. In conclusion, half of the studies were successful and had an effect on either overweight or obesity. Much more research is needed in order to effectively prevent paediatric obesity.
