In this paper are reviewed 47 universal prevention programs on eating disorders and disordered eating published in the period 1993-2011, mainly administered in schools and aimed at children and adolescents. In each program have been revised the elements linked to the design (methodological rigor, follow-up, control group, specificity, covert approach, replication, effectiveness, areas of application and measures). This review allows analyze the evolution of this field of study in the specified period. Progressively has been increased the rigor and methodological sophistication of designs, but they are still with some major problems, such as the absence of a set of agreed measures, among others. Finally, we suggest some elements of debate on the future direction to be taken by the development of new prevention programs in this area. Among others, the need to adapt to male population, ideal characteristics of target population in age and level of risk, the specific content that should be worked, the theoretical approach which should be based, about the intensity and duration, and the need to integrate the prevention of eating disorders and obesity.
