Background Binge-eating disorder (BED) as a distinct eating disorder category and night eating syndrome (NES) as a form of Other Specified Feeding or Eating Disorders were recently included in the 5th edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). This study sought to investigate the prevalence of BED and NES and associations with various forms of nonnormative eating behavior and psychopathology in prebariatric patients. Within a consecutive multicenter registry study, patients in 6 bariatric surgery centers in Germany were recruited. Methods Overall, 233 prebariatric patients were assessed using the Eating Disorder Examination and self-report questionnaires. Assessment was unrelated to clinical procedures. Results Diagnostic criteria for full-syndrome BED and NES were currently met by 4.3% and 8.2% of prebariatric patients, respectively. In addition, 8.6% and 6.9% of patients met subsyndromal BED and NES criteria, respectively. Co-morbid BED and NES diagnoses were present in 3.9% of patients. In comparison to patients without any eating disorder symptoms, patients with BED and NES reported greater emotional eating, eating in the absence of hunger, and more symptoms of food addiction. Moreover, differences between patients with BED and NES emerged with more objective binge-eating episodes and higher levels of eating concern, weight concern, and global eating disorder psychopathology in patients with BED. Conclusion BED and NES were shown to be prevalent among prebariatric patients, with some degree of overlap between diagnoses. Associations with nonnormative eating behavior and psychopathology point to their clinical significance and discriminant validity. © 2015 Published by Elsevier Inc. on behalf of American Society for Metabolic and Bariatric Surgery.

Background Physical activity (PA) seems to be important for long-term weight loss after bariatric surgery; however, studies provide evidence for insufficient PA levels in bariatric patients. Research found self-efficacy to be associated with PA and weight bias internalization, for which an influence on mental and physical health has been shown in recent studies. The purpose of the present study was to investigate the influence of general self-efficacy on PA, mediated by weight bias internalization. Methods In 179 bariatric surgery candidates, general self-efficacy, weight bias internalization, and different intensities of PA were assessed by self-report questionnaires. Structural equation modeling was used to analyze the assumed mediational relationship. Results After controlling for sociodemographic variables, weight bias internalization fully mediated the association between general self-efficacy and moderate-intense as well as vigorous-intense PA. Lower general self-efficacy predicted greater weight bias internalization, which in turn predicted lower levels of moderate-intense and vigorous-intense PA. Conclusions The results suggest an influence of weight bias internalization on preoperative PA in bariatric surgery candidates. Subsequently, implementation of interventions addressing weight bias internalization in the usual treatment of bariatric surgery candidates might enhance patients' preoperative PA, while longitudinal analyses are needed to further examine its predictive value on PA after bariatric surgery. © 2015 American Society for Bariatric Surgery.

Objective Weight bias internalization (WBI) is associated with eating disorder psychopathology and non-normative eating behaviors among individuals with overweight and obesity, but has rarely been investigated in prebariatric patients. Based on findings demonstrating a relationship between emotion dysregulation and eating behavior, this study sought to investigate the association between WBI and eating disorder psychopathology as well as non-normative eating behaviors (i.e., food addiction, emotional eating, and eating in the absence of hunger), mediated by emotion dysregulation. Method Within a consecutive multicenter study, 240 prebariatric patients were assessed using self-report questionnaires. The mediating role of emotion dysregulation was examined using structural equation modeling. Results The analyses yielded no mediational effect of emotion dysregulation on the association between WBI and eating disorder psychopathology. However, emotion dysregulation fully mediated the associations between WBI and emotional eating as well as eating in the absence of hunger. Further, emotion dysregulation partially mediated the relationship between WBI and food addiction symptoms. Discussion Prebariatric patients with high levels of WBI are at risk for non-normative eating behaviors, especially if they experience emotion regulation difficulties. These findings highlight the importance of interventions targeting WBI and improving emotion regulation skills for the normalization of eating behavior in prebariatric patients. © 2015 Wiley Periodicals, Inc.
