Epidemiology of eating disorders part II: an update with a special reference to the DSM-5

The present article is the second one of three about the epidemiology of eating disorders. The first introductory article outlined basic epidemiological issues, approaches and concepts and provided a historical panorama of the epidemiology of eating disorders. The present paper presents an updated review about the incidence and prevalence of eating disorders and eating problems. A particular concern is to discuss the impact of using the DSM-5 for case definitions. Moreover, the current paper will discuss recent findings with respect to outcome distributions. Finally, advances within analytic epidemiology are discussed in terms of risk for onset and predictors of outcome and how recent evidence may increase the potentials for prevention or other social epidemiology strategies.
