Effect of binge eating on treatment outcomes for smoking cessation

Abstract

Introduction: This study investigated the effect of binge eating on smoking cessation outcomes. Methods: Participants (n = 186) reported binge eating status at baseline and at a 6-week postquit evaluation during a larger clinical trial for smoking cessation. Binge eating was defined with a single self-report questionnaire item from the Dieting and Bingeing Severity Scale. Participant groups defined by binge eating status were compared on abstinence rates. Results: Among participants, 22% reported binge eating at baseline, 17% denied binge eating at baseline but endorsed binge eating by 6 weeks, and 61% denied binge eating at both timepoints. Participants who reported binge eating prior to or during treatment had lower quit rates at 6-week postquit and at the 24-week follow-up point than those without binge eating; the groups did not differ at the 12-week follow-up point. The group that experienced an emergence of binge eating reported significantly more weight gain than the other groups. Conclusions: These results suggest that treatments addressing problematic eating behaviors during smoking cessation are warranted. © The Author 2010.
