Prevención de la obesidad desde la actividad física: del discurso teórico a la práctica

Childhood obesity has increased considerably in most countries in recent years. Obese children already have many co-morbidities since infancy, which can have serious consequences in adulthood. From a health standpoint, the most appropriate to address this problem is primary prevention. This article aims to summarize the relevant aspects from the point of view of prevention of childhood obesity, and in particular to those related to physical activity. To this end, health and education professionals have a role. In all cases, it is necessary to perform the evaluation of programs to see if they are really effective. Developing new programs should be based on previous experiences that had positive results. As most interventions to date have not been very effective, much more research is needed in this area in the future.
