ABSTRACT The aim of the present study was to find factors that predict the short-term outcome of inpatients with anorexia nervosa (AN).
Female inpatients with AN (N = 100) were divided into treatment completers (N = 50) and drop-outs (N = 50). Using stepwise linear regression the relationship of demographic data, illness history and patterns of weight gain to BMI gain up to discharge were analysed.
Among drop-outs, 69% of the variance in BMI gain up to discharge was explained by length of the first half of treatment (FHT), average weekly BMI gain and average weight loss during FHT. Among completers, 52% of the variance in BMI gain up to discharge was explained by BMI at admission and average weekly BMI gain during the second half of treatment (SHT).
Weight curves offer important information about short-term outcome for patients with AN.
