Abstract: In response to the high prevalence of obesity, eating disorders and disordered eating behaviors among youth, researchers in both the obesity and eating disorders fields have proposed using an integrated approach to prevention that addresses the spectrum of weight-related disorders within interventions. The identification of risk factors that are shared between these weight-related disorders is an essential step to developing effective prevention interventions. This article provides preliminary support for the existence of shared risk factors for obesity and eating disorders. Specifically, the authors examined and found preliminary evidence that dieting, media use, body image dissatisfaction and weight-related teasing may have relevance for the development of the spectrum of weight-related disorders. Future etiologic research designed to specifically test these and other potentially shared risk factors is needed and would provide important insights into the relevant factors to be addressed in interventions aimed at preventing a broad spectrum of weight-related disorders.
