Antecedents and consequences of binge eating episodes in women with an eating disorder.

The aim of this study was to explore antecedents and sequelae of binge eating episodes. A sample of eating disorders (n = 154 women) was selected from a total of 1849 female respondents (out of 2500) recruited as part of a general population-based survey. Included participants met DSM-III-R criteria for anorexia nervosa (AN), bulimia nervosa (BN) or eating disorder not otherwise specified (EDNOS) based on the Survey for Eating Disorders (SEDs). Preliminary criteria for binge eating disorder (BED) were added. Results indicated that the most frequently reported antecedents and consequences of binge eating were emotional and physiological factors. There were significant differences between the different ED subgroups in their frequency of binge eating episodes. Regarding antecedents of a binge eating episode, the SEDs-defined ED subgroups had overall differences in frequency on "stomach feeling". In particular, the BN-group reported "euphoria" more frequently than the BED and EDNOS-groups. Concerning consequences of a binge eating episode, there were overall differences between the ED subgroups on "fall asleep", and in addition a borderline significance was found for "disturbed by others" (p = 0.059). None of the eight women in the AN group reported "euphoria" as a factor that terminated a binge eating episode. The findings may have important implications with regard to prevention and treatment of ED.
