    Summary points

    • Few obesity prevention interventions have been shown to be effective in children

    • Comprehensive strategies that tackle diet and physical activity as well as providing psychosocial support and environmental change may help prevent obesity

    • Community based interventions aimed at changing activity levels, dietary knowledge, and eating behaviour may be useful but need evaluation for effectiveness and cost effectiveness

    • Specialist treatment may include treatment with sibutramine or orlistat in children over 12, although long term studies are needed

    • Surgery is recommended only in adolescents with extreme obesity, in limited circumstances, but the benefits need to be balanced against the possible side effects

    In the first part of this article we described how obesity in children is measured, its prevalence, whether children should be screened, and the risk factors for and consequences of obesity.1 In this part we review the current evidence on the prevention and management of childhood obesity.

    Sources and selection criteria

    This review draws on the Foresight report, guidance from the National Institute for Health and Clinical Excellence and the Australian National Health Medical Research Council, and Cochrane review.

    In April 2008 we searched the Cochrane Library database of reviews and the Centre for Reviews and Dissemination databases using the search term “obesity”. We also conducted a Medline search ((Child$ or paediatric or pediatric or adolescent) and (Obes$ or overweight)) limited to 1 January 2005 to 6 May 2008 and “review articles”; this identified 1105 articles. We read the abstracts of these articles and retrieved relevant papers. We also used articles from our own bibliographies collected over the past 10 years.

    The evidence to support the measurement, prevention, and management of obesity in children is still relatively weak, with few randomised controlled trials or systematic reviews. The strength of evidence is developing and the updated Cochrane review that will be published in 2009 …
