In order to gain effectiveness against the worldwide spread of obesity it has been recommended by high health offices and scientific societies caring for adults to begin at the earliest possible time. This was also the pediatric point of view based on prevalence trends, clinical burden (comorbidities already in pediatric age), tracking and poor therapeutic results. Because of the population growth this problem will not be solved easily.
Types of prevention:The three levels of prevention primary (before the disease), secondary (latent disease) and tertiary (for disease consequences) plus the fourth holistic level, when carried out in practice fall on the classical questions: What, When and How, issued by WHO Population Health Promotion. What kind of prevention? The answer would be general and individual. The general approach is crowded by a great extent of plans and guidelines; therefore the evidence based policies are and will be applied to clear the overlapping and sometimes confusing panorama. Who is the recipient of prevention? This has been changed because of the notion of earliest prevention that should start preconceptionally, going on during pregnancy and newborn period. The negative consequences of high birth weight are clearly demonstrated. Even the classical age to start prevention (4-6 years) is receding in favor of the early rebound of BMI. How prevention is carried out? The present ways should be based on demonstrated plans, but a lot of very varied norms appear, although these seem unable to improve the problem. New interventions for pediatric population are analyzed and the common points of action are: Reduction of energy intake, Increase energy expenditure, Involvement of parents/ family, appropriate information to child or adolescent.In this panorama of good prevention programs yet increased prevalence trends of obesity in the world it is clear that something new must be done but it has not been defined yet. In the meantime this succinct analysis of positive facts and done negative issues, will perhaps contribute step by step to improve the obesity prevention future.
