"There is evidence of an overlap of symptoms between binge-eating disordered (BED) and bulimia nervosa non-purging (BN-NP) patients. In addition, there are indications of an evolution from bulimia nervosa to BED along a continuum of vulnerability. However, DSM-IV categorizes BED and BN-NP as distinct disorders based on clinical characteristics," scientists in Belgium report.
"In this study weight history and personality-related characteristics (TCI; Cloninger, Svrakic, & Przybeck, 1993) were studied in 30 BED and 17 BN-NP patients," stated Myriam Vervaet and colleagues at Ghent University Hospital. "BED patients were older, and had a longer duration of illness, a larger weight cycling, a higher current and previous BMI, and a lower score for the temperament dimension 'Persistence' than BN-NP patients. After correcting for age, differences between weight variables remained, including comparatively higher BMIs and larger weight fluctuations among the BED patients.
"A possible explanation is that this difference is due to a genetic effect of the propensity to be overweight and the temperamental characteristic of Persistence," reported the investigators. "This ...
