Document Summary

There are two important periods of adolescence for eating disorders, early passage into adolescence and transition from later adolescence into young adulthood. Childhood risk factors such as eating problems, dieting patterns, and negative body image may cause teens to exert excessive control over their eating as a way to manage stress and physical changes. The restraint pathway theoretical model for understanding body dissatisfaction/disordered eating starts with an internalization of societal ideals of beauty/thinness plus a discrepancy between actual and ideal body shape, which leads to dieting/binging/purging. The interpersonal vulnerability theoretical model for understanding body dissatisfaction/disordered eating starts with inadequate nurturing, plus a disturbance in self-image and social functioning, plus feelings of ineffectiveness leads to body dissatisfaction and disordered eating. Anorexia is characterized by refusal to maintain minimally normal body weight; intense fear of gaining weight; and significant disturbance in perception and experiences of body size. Dsm-5 subtypes include the restricting type, and the binge-eating/purging type.
