Objective: To replicate our previous findings of an association between energy density and diet variety in recently weight-restored patients with anorexia nervosa (AN) and clinical outcome in the year following treatment.
Method: Nineteen hospitalized, weight-restored women with AN completed a food record, from which a diet energy density score (DEDS) and a diet variety score (DVS) were calculated. After hospital discharge, patients were contacted regularly; at the end of one year, clinical outcome was determined using modified Morgan-Russell criteria. As in our previous study, outcome was dichotomized into "full, good, or fair'' and "poor'' groups.
Results: Data from 16 subjects were available. The DEDS was significantly lower (p < .05) in the poor outcome group (0.7 +/- 1) compared with the "full, good, or fair'' outcome group (0.9 +/- 1). Although the DVS was also lower in the poor outcome group (13.9 +/- 2) compared with the "full, good or fair'' outcome group (15.7 +/- 1.8), this difference was not statistically significant.
Discussion: In recently weight-restored patients with AN, a lower DEDS, but not DVS, is associated with poor clinical outcome after inpatient treatment. This finding may be important in the assessment of risk for relapse in patients with AN.
