Childhood obesity undermines the physical, social and psychological well-being of children and is a known risk factor for adult obesity and noncommunicable diseases. There is an urgent need to act now to improve the health of this generation and the next. The Commission recognizes that the scope of potential policy recommendations to address childhood obesity is broad and contains a number of novel elements. However, it is only by taking a multisectoral approach through a comprehensive, integrated package of interventions that address the obesogenic environment, the life-course dimension and the education sector, that sustained progress can be made. This requires government commitment and leadership, long-term investment and engagement of the whole of society to protect the rights of children to good health and well-being. The Commission believes that progress can be made if all actors remain committed to working together towards a collective goal of ending childhood obesity.
