Excess weight in adolescents is associated with an increased risk of disorders such as hyperlipidemia and type 2 diabetes5 and can result in decreased emotional and physical quality of life.6,7 In addition, childhood obesity results in increased risk of morbidity and mortality in adulthood.8,9 Long-term follow-up studies of children and adolescents indicate that overweight children have a 15-fold greater risk of becoming overweight adults compared with those children and adolescents who were not overweight.8 Effective weight management in children and adolescents may therefore have important immediate and future societal health benefits.
