- Abstract
Background: Problematic eating behaviors and general psychopathology have been associated with poor weight loss after bariatric surgery. However, little is known about how these aspects impact weight loss outcomes for the increasing number of patients undergoing reoperative surgeries. This study compares disordered eating and weight-related outcomes before and 6 months after surgery in patients undergoing primary (P-Group) and reoperative bariatric surgery (R-Group).Methods: This longitudinal study assessed 122 P-Group and 116 R-Group patients before and 6 months after surgery. The assessment included the eating disorder examination diagnostic items, and a set of self-report measures assessing eating disorder symptomatology, grazing, depression, anxiety, and negative urgency.Results: Preoperatively, no differences were found between the R- and P-Groups in terms of disordered eating-related variables (except for shape concern, which was higher for the R-Group). At 6 months after surgery, the R-Group revealed significantly higher values for restraint (F(1,219) = 5.84, p = 0.016), shape (F(1,219) = 5.59, p = 0.019), weight concerns (F(1,219) = 13.36, p = 0.000), depression (F(1,219) = 7.17, p = 0.008), anxiety (F(1,219) = 6.94, p = − 0.009), and compulsive grazing (F(1,219) = 6.13, p = 0.014). No significant pre- or post-surgery predictors of weight loss were found for the P-Group (χ2 = 0.70, p = 0.872). In the R-Group, post-surgery anxiety (Waldχ2(1) = 6.19, p = 0.01) and the post-surgery number of days with grazing in the previous month (Waldχ2(1) = 3.90, p = 0.04) were significant predictors of weight loss.Conclusion: At 6 months after surgery, the R-Group presented more problematic eating and general psychological distress, which may put these patients at greater risk of poorer long-term weight outcomes.
