title: [Strategies for obesity prevention in children and adolescents].
abstract: Few studies on treatment or prevention of obesity have shown significant results. Theoretically, in children and adolescents as compared to adults, prevention of excessive weight gain should be easy due to the energy expended during growth, associated with more time spent in leisure-time activities. However, numerous factors that stimulate overeating and sedentary behaviors are difficult to overcome. Additionally, most intervention studies have focused on a minor portion of the many factors associated with obesity. Important aspects of the obesity epidemic such as the role of the food industry, fast food chains, advertising, and a lifestyle that limits children to sedentary activities and overeating cannot be explored by a traditional clinical trial design. At any rate, among the published interventions, those including the family in weight-reduction strategies have shown the best results, as compared to children-centered approaches. Meanwhile, studies on specific nutrient or dietary composition (such as calcium, protein, or glycemic index) related to prevention or treatment of obesity have failed to yield good results. Reducing the intake of high-sugar carbonated drinks and juices has shown promising but still inconclusive results.
