Studies of the epidemiology of bulimia nervosa.
ABSTRACT Research on the epidemiology of bulimia nervosa has focused largely on the prevalence of the disorder. As methods have improved, consensus has increased regarding the prevalence rate among adolescent and young adult women--about 1%. However, the accuracy of this figure and its clinical significance must be questioned. In this synthesis of the epidemiological work to date, the authors review the literature from a clinical and research perspective. They recommend a shift in emphasis away from studies of the distribution of the disorder toward studies of the determinants of the whole spectrum of the disturbance that exists in the community.

ABSTRACT: A previous study found that self-reported body dissatisfaction, depression, and peer pressure to maintain a thin body shape were significant predictors of bulimic behavior in college women, but that family functioning was not a significant predictor [Eat. Behav. 2 (2001) 323]. The current study examined whether perfectionism, low self-esteem, and a more specific family variable—perceived pressure from the family to be thin—predicted any additional variance in eating-disordered behavior after significant variables from the previous study had been taken into account. As in the previous study, self-reported body dissatisfaction, depression, and peer pressure to maintain a thin body shape were significant predictors of bulimic behavior. Perceived weight-related pressure from the family was also a significant predictor. In contrast, high parental expectations were found to predict lower levels of bulimic behavior and to moderate the effects of peer influence on bulimic behavior. The variables found in this study to be related to bulimic behavior may be useful targets for clinical intervention for women with disturbed eating patterns.Eating Behaviors 05/2004; DOI:10.1016/S1471-0153(04)00047-9 · 1.58 Impact Factor
