Bulimia Nervosa with History of Anorexia Nervosa: Could the Clinical Subtype of Anorexia Have Implications for Clinical Status and Treatment Response?

Objective: To investigate whether the subtype of anorexia nervosa (AN) could influence the bulimic syndrome and treatment response in bulimia nervosa (BN) patients with a history of AN (BN/AN+). Method: Seventy female BN patients were assessed for eating disorder, psychopathology and personality, and treated for 6 months. Results: BN/AN+ patients retained some traits of their past condition: lower body weight, higher perfectionism, and higher reward dependence. They also had more severe symptoms, longer evolution time, and worse response to treatment. A history of restricting AN was associated to higher age, longer evolution time, higher impulsivity, and greater tendency to use diet pills and diuretics. A history of binge-purging AN was associated to more severe vomiting, lower body dissatisfaction and less depressive symptoms, as well as better outcome. Discussion: The influence of the AN subtype in BN/AN+ patients is worthy of further study as it might have clinical implications. (C) 2010 by Wiley Periodicals, Inc.
