Abstract

Objective: Bodyweight restoration is one of the most important targets in adolescent inpatient treatment of anorexia nervosa (AN). This study examined the association between achieving target weight and rehospitalization in two groups of adolescents with AN and atypical anorexia nervosa (AAN) admitted to a specialized inpatient unit. Method: Included were 202 adolescent patients hospitalized in a specialized eating disorder unit, 10–18 years old. One hundred fifty-four adolescents were diagnosed with AN, and 48 with AAN. We examined the patients' demographic and clinical characteristics, the achievement of treatment goals, and their rehospitalization history within a year of discharge from the unit. Results: Log-linear regression indicated a significant association between achieving target weight during the inpatient program and rehospitalization at one-year follow-up in the AN group; this association was not significant in the AAN group. Discussion: This study emphasizes the importance of differentiating patients with AAN from those with classical AN. Specifically, it raises questions about the predictive power of target weight at discharge in preventing relapse and its centrality in determining AAN patients' treatment plans.
