AIMS: To further investigate the differentiation between non-purging bulimia nervosa (BN-NP) and binge eating disorder (BED), particularly as concerns weight-shape overconcern affecting self-esteem, a core belief to both anorexia and bulimia nervosa. METHODS: Twenty-five female subjects with BN-NP and 25 female subjects with BED, consecutively referred to the Eating Disorder Unit of the DPPhNB, were administered the BEDCI, the EDI-2 and the BUT. RESULTS: BED patients had a higher BMI (35.5 vs. 23.8 kg/m2, p<0.0001) and were slightly older than BN-NP ones. Weight-shape concerns as one of the main/the most important things influencing self-esteem were reported by 68% of BN-NP patients and 62.5% of BED ones. Age at onset of binge-eating, weight-cycling, overall impairment due to the eating behavior, sexual harassment, depressive and substance abuse comorbidity were equally represented in the two groups of patients. BN-NP patients scored higher than BED ones as regards EDI drive for thinness (p<0.05) and BUT weight phobia (p<0.05), with these scores significantly related to differences in BMI (p<0.0005 and p=0.012). Weight-shape overconcern influencing self-esteem was predictive of an earlier onset of binge-eating (p<0.05) and higher scores at the BUT weight phobia, and body image concerns (p<0.05). CONCLUSIONS: Differences between BED and BN-NP seem to be more of degree than type and there seems little value in the separation between BED and BN-NP based on weight-shape concerns that substantially impair self-esteem. This construct seems core to both disorders and plays a substantial role in triggering and maintaining the binge-eating cycle.
