Abstract

Objectives We explored the severity of binge eating, loss of control over eating, emotional eating, and night eating before bariatric surgery and annually for 3 years following surgery. We also assessed the impact of post-operative eating psychopathology on weight outcomes.Methods Eight hundred forty-four patients participated in this prospective cohort study. Demographic factors, self-report measures of eating pathology (BES, NEQ, EES, EDE-Q), and weights (kg) were collected pre-surgery and annually for 3 years after surgery.Results The severity of problematic eating behaviors decreased after surgery and remained lower than baseline throughout follow-up. An increase was noted in binge eating scores (change in mean score ± SD = 0.85 ± 4.71; p = 0.002), emotional eating scores (2.00 ± 13.63; p = 0.033), and loss of control eating scores (1.11 ± 7.01; p < 0.001) after the first post-operative year that continued to the third post-operative year. There was also an increase in night eating scores between 2 and 3 years post-surgery (2.52 ± 8.00; p = 0.01). Higher 1-year post-operative binge eating scores were a significant predictor of lower 2-year % total weight loss (β = - 0.39, confidence interval (CI) - 1.23, - 0.16, p = 0.012).Conclusions The severity of problematic eating behaviors decrease after bariatric surgery, but increase significantly between the first and third post-operative years. Binge Eating Scale score at 1 year post-surgery was the only significant predictor of reduced percent total weight loss at 2 years. Additional prospective studies with adequate power are required to assess the progression of these eating pathologies beyond 3 years and their impact on weight outcomes beyond 2 years.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Beyond 18 months after bariatric surgery, results on emotion-based eating are mixed, with some studies suggesting attenuation through 36 months and others finding reoccurrence between 12 and 36 months.

    “Results beyond the 18-month timeframe are mixed, with some studies suggesting attenuation of emotion-based eating through 36 months after having bariatric surgery and other studies finding reoccurrence between 12 and 36 months after having bariatric surgery (33–39).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
