Anatomy of a binge: food environment and characteristics of nonpurge binge episodes.

This secondary analysis prospectively examined nonpurge binge eating patterns in a naturalistic setting in 48 nonpurge binge eating women. Binge eating episodes were analyzed from 14-day food diaries to describe the binge and to determine how types of foods consumed and setting variables affected nonpurge binge eating women. Findings indicated that binge episodes occurred mostly during the lunch (27.1%) and dinner hours (45.8%) and on weekends (62.5%). Half of the binge episodes occurred in restaurants. The most common items consumed during binges were breads/pasta (64.6%), sweets (56.2%), high fat meat items (45.3%), and salty snacks (39.6%) while the predominant foods consumed during these binges were high fat meat items (29.2%), sweets (21.0%), and salty snacks (18.8%). Those who predominantly binged on sweets had significantly more binge days [t(46)=-2.8, p<.01]. Women who predominantly binged on fried meat had significantly higher body mass index (BMI) [t(46)=-2.8, p<.01]. A higher BMI was also associated with binging during meals rather than binging during snacks [t(46)=2.4, p<.05]. The results suggest that nonpurge binge eating patterns are more problematic during meal times.
