Résumé fourni par la source

More and more children worldwide are overweight or obese, increasing their risk of medical problems including non-communicable diseases, and psychosocial problems including self-esteem, depression and bullying. A team from Australia, the United Kingdom and Hong Kong reviewed trials that evaluated interventions promoting healthier diets and increased physical activity to prevent children from becoming overweight and obese. The last search for the Cochrane Review was conducted in March 2010. Randomised and non-randomised controlled trials of at least 12 weeks duration that compared interventions targeting dietary behaviour, physical activity, or both with no intervention or a different intervention in children aged from 0 to 18 years old were included. Body mass index (BMI) was the main outcome. Fifty-five studies were included, 50 in high-income countries, mostly North America. Thirty-nine studies included children aged between 6 and 12 years and 41 studies ranged between 12 and 52 weeks. The most common setting for interventions was schools in 43 studies. The meta-analysis included 37 studies (27 946 children). A funnel plot suggested that some small studies that did not demonstrate an effect may not have been published, potentially influencing the meta-analysis.
