title: Mood change during weight restoration in patients with anorexia nervosa.
abstract: OBJECTIVE
  Although depression is known to co-occur with anorexia nervosa (AN), there are few clear studies of mood in the context of weight gain treatment without the use of medication.
  
  
  METHODS
  Twenty-one patients admitted consecutively to an inpatient clinical research unit normalized weight to at least 90% of ideal body weight (IBW). Depression was assessed at admission and weight normalization (pre-discharge) with the Beck Depression Inventory (BDI).
  
  
  RESULTS
  Multivariate F tests showed BDI scores to be significantly improved across these two time points (BMI: F(2,20) = 166.58, p = 0.000; BDI: F(2,19) = 22.64, p = 0.000). Moreover, improvement in mood was also evident at partial weight restoration (80% IBW).
  
  
  CONCLUSIONS
  Patients with AN undergoing nutritional rehabilitation and psychotherapy on an inpatient unit present with significant depressive symptoms as measured by the BDI, and, with weight restoration, demonstrate statistically significant improvement in mood symptoms without the use of adjunctive medication. Data at partial weight restoration suggest that these results cannot be explained by improved mood related to anticipation of discharge.
