To identify factors influencing the course of anorexia nervosa (AN) over time.
Former female patients with AN (36 remitted and 24 nonremitted) and 31 healthy females responded to standardized interviews and self-rating questionnaires. Remitted patients maintained normal eating, normal weight, and regular menses for the past 12 months. Patients not fulfilling these criteria were considered nonremitted.
Using logistic regression, we identified that number of hospitalizations, duration of ambulatory treatment, past vegetarianism, past anxiety, and childhood sexual abuse differentiated remitted from nonremitted patients, predicting nonremission. A similar analysis identified that elevated follow-up vegetarianism and eating-related concerns and lower body mass index (BMI) differentiated remitted from nonremitted patients, contributing to nonremission. Univariate analyses identified that remitted patients had elevated anxiety and eating-related obsessionality compared with the controls, suggesting these variables to potentially predispose to AN.
Elevated anxiety and eating-related obsessionality may increase the risk for the development of AN and for nonremission. © 2008 by Wiley Periodicals, Inc. Int J Eat Disord 2009
