Eating disorder severity and psychological morbidity in adolescents with anorexia nervosa or atypical anorexia nervosa and premorbid overweight/obesity.

A significant proportion of adolescents with anorexia nervosa (AN) or atypical anorexia nervosa (AAN) experience premorbid overweight/obesity, yet distinct characteristics among this subset of patients remain unclear. This study examined eating disorder (ED) symptom severity, psychological morbidity, and weight stigma in patients with premorbid overweight/obesity as compared to patients with premorbid normal weights.
