Body weight as a prognostic factor for day hospital success in adolescents with anorexia nervosa.

For female adolescents with anorexia nervosa, body weight at admission as a predictor of treatment outcome in the day hospital setting was examined. A retrospective review of patient charts was completed to determine success or failure in the day hospital program based on weight above or below 85% of ideal body weight. There was not a greater risk of failure in the day hospital program for patients with ideal body weight below 85% compared to those patients with an ideal body weight of ≥ to 85%. Body weight did not predict day hospital success in adolescents with anorexia nervosa in this study.
