Associations of COVID-19 Lockdowns on Eating Behaviors and Body Mass Index in Patients with a History of Bariatric Surgery: a Cross-Sectional Analysis

Introduction: Few studies have explored the impact of the COVID-19 pandemic on the eating behaviors, dietary quality, and changes in weight of postoperative bariatric surgery patients. Methods: A cross-sectional survey on eating behaviors and attitudes toward food was emailed or given to patients who had bariatric surgery before March 2020. Patient charts were reviewed for weight measures. Results: Seventy-five (71.43%) patients experienced weight recurrence with an average increase in body mass index (BMI) of 2.83 kg/m² (SD: 2.19). The majority of patients reported no symptoms of binge eating (n = 81, 77.14%) with 16 (15.24%) qualifying for loss of control eating (LOCE). LOCE was significantly associated with grazing behavior (p = 0.04), emotional over-eating (p = 0.001), and food responsiveness (p = 0.002). LOCE was negatively associated with dietary quality (p = 0.0009) and satiety responsiveness (p = 0.01). Grazing behavior was significantly associated with emotional over-eating (p < 0.0001) and food responsiveness (p < 0.0001) as well as negatively associated with dietary quality (p < 0.0001). Slow eating was negatively associated with grazing (p = 0.01), emotional over-eating (p = 0.003), and food responsiveness (p < 0.0001). When included in a regression model controlling for age and sex, emotional over-eating was a significant predictor of weight recurrence (β = 0.25; p = 0.04). Conclusion: Our results suggest that maladaptive eating behaviors contributed to LOCE and poor dietary quality during the COVID-19 pandemic; however, slow eating may be protective against grazing, emotional over-eating, and food responsiveness.
