Key result
Postsurgery binge eating and sedentary time linked to ~8% greater weight regain after gastric bypass.
Why the study?
There is considerable variation in the magnitude of weight regain after Roux-en-Y gastric bypass surgery, highlighting the importance of patient-level factors.
Do specific patient behaviors affect weight regain in adults after Roux-en-Y gastric bypass surgery?
Population
1278 adults who underwent RYGB with adequate follow-up from 6 US cities
Comparison
Specific postsurgery behaviors vs reference behaviors
Design
Prospective cohort study
Follow-up
Median 6.6 years

May warrant postoperative behavioral screening after RYGB; hypothesis-generating and requires prospective trials before changing practice.

Do specific patient behaviors affect weight regain in adults after Roux-en-Y gastric bypass surgery?
Mean Difference: 8 (95% CI 5.1–11)
Specific postsurgery behaviors, such as binge eating and increased sedentary time, are independently associated with greater weight regain after Roux-en-Y gastric bypass.
King et al. (2019) conducted a cohort in Weight regain after Roux-en-Y gastric bypass (n=1,278). Postsurgery eating behaviors and sedentary time vs. Reference groups (e.g., lowest quartile, absence of behavior) was evaluated on Weight regain (percentage of maximum weight lost) (MD 8.0%, 95% CI 5.1-11.0). Postsurgery behaviors including binge eating (mean difference 8.0%; 95% CI 5.1-11.0) and sedentary time were independently associated with weight regain after Roux-en-Y gastric bypass.
