In our adolescent inpatient unit in France, 268 girls (mean age=16.7 years, SD=2.0) were hospitalized between 1996 and 2004. The mean duration of illness was 20.4 months (SD=17.1, median=13.9). When we considered dropouts as all subjects who did not achieve their therapeutic contract (did not reach the target weight for discharge) (6), we found a dropout rate of 24.6% (N=66). One-half were staff-initiated, and one-half were patient-initiated. Only six of 66 (9%) were discharged at the first part of their therapeutic contract (early dropouts). As usual, with the youngest patients, the purging subtype was rare (N=51, 19%). To examine dropout predictors, we performed a step-by-step backward logistic regression analysis. We considered 13 predictive variables reported by the literature (1–4): body mass index (kg/m2) at admission, maximum and minimum previous body mass indexes, age at admission, length of hospitalization, time since first treatment, duration of illness, anorexia nervosa subtype, number of previous hospitalizations, body mass index at discharge, age at onset, educational status, and socioeconomic status.
