Abstract

Introduction While depression generally improves after bariatric surgery, less is known regarding heterogeneity in long-term symptom change. Given that depressive symptoms have been associated with weight change following bariatric surgery, identifying and characterizing subgroups with more severe depressive symptoms may have prognostic utility for understanding post-surgical weight loss. This study sought to characterize patterns of change in depressive symptoms and evaluate associations with weight loss in the seven years following bariatric surgery.Methods Participants were 2308 patients who underwent bariatric surgery as part of the Longitudinal Assessment of Bariatric Surgery-2 (LABS-2) study. Depressive symptoms (measured by the Beck Depression Inventory) and weight were assessed annually following surgery.Results A group-based trajectory model identified six subgroups that evidenced distinct patterns of change in depressive symptoms, with the majority (87.0%) exhibiting stable low to average levels. Generalized linear mixed models indicated trajectory groups differed in percent total weight loss (%TWL), with trajectories characterized by initial decreases in depressive symptoms over the first two years (5.2% of participants) experiencing the highest %TWL (20.7% vs. 14.9-18.4% in the other trajectories at 7 years).Conclusions Findings demonstrate meaningful heterogeneity in the pattern of changes in depressive symptoms after surgery. While most patients experience relatively low stable levels of depressive symptoms, those who have initial symptom improvement demonstrate the greatest magnitude of weight loss. Further research is necessary to explore the directionality of this association and the time-varying mechanisms by which depression and weight may mutually influence each other.

  • As negative emotional states return and the honeymoon period after bariatric surgery ends, patients may find themselves craving food to manage negative emotions.

    “Over time, as negative emotional states may return and the “honeymoon period” after having bariatric surgery ends, patients may find themselves craving food to manage negative emotions (43, 44).”

    From Behavioral Interventions to Attenuate Driven Overeating and Weight Regain After Bariatric Surgery (2022) · cites this paper as [44]

    The Discussion (page unavailable) reports that a small minority of patients had depressive symptoms increase or rebound after an initial decline, supporting the possibility that negative emotional states return. It does not describe a “honeymoon period” ending or patients craving food to manage negative emotions; it instead raises loss of appetite as a possible manifestation of depression in the rebound group.

  • Symptoms of depression typically improve in the first year after bariatric surgery, but these improvements may erode over time.

    “Symptoms of depression typically improve in the first year after having bariatric surgery, but these improvements may erode over time (44), and there is some evidence that many patients increase their antidepressant medications after having bariatric surgery (67).”

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.
