| A model of the dual etiology of eating disorders is proposed to account for various inconsistencies in the eating disorders research literature. The model was developed following a thorough review of the quantitative and qualitative literature related to anorexia, bulimia, and obesity. Eating disturbances are conceptualized as nonspecific symptoms of distress in one or many areas of life (primary etiology) which have biological, psychological, and social consequences (secondary etiology) that can give rise to an eating disorder. Theory and research from fields such as nutrition and neurochemistry were integrated to advance the understanding of secondary etiological factors. The research and treatment implications of separating primary and secondary etiological factors are discussed. |
