[Psychological, social and cultural factors of overweight and obesity in children and adolescents in México].

Child obesity is a serious problem of public health in México. If we don't reverse it quickly, it will generate unsustainable economical consequences to the health institutions in this country, as well as serious health problems. This article reviews some psychological, social and cultural factors in the health-illness process, in particular in relation to food choices, the function of the family, and the food-related parental practices, changes in physical activity, and the role of media. As a conclusion, we can say it is very important to take into account psychological and cultural aspects, as well as the family as a whole in the creation of public policies in the fight against the obesity epidemic. Other fundamental aspect to bear in mind is the generation and effective monitoring of regulations on food advertising, particularly that aimed to children, and also in regards to a labelling of edible products accessible to all people. An interdisciplinary work is essential to generate synergies that help us to control obesity in the first place, and then to be able to reverse this problem, without disregarding the role of prevention.
