Research Article: Prevalence and short-term change in symptoms of anxiety and depression following bariatric surgery: a prospective cohort study

Date Published: 2024-01-03

Abstract:
Objectives Bariatric surgery is an effective treatment for severe obesity that leads to significant physical health improvements. Few studies have prospectively described the short-term impact of surgery on mental health using standardised case-finding measures for anxiety or depressive disorders. This study describes the prevalence and short-term course of these conditions following surgery. Design Prospective observational cohort study. Setting 12 National Health Service centres in England. Participants Participants studied took part in the By-Band-Sleeve study, a multicentre randomised controlled trial evaluating the surgical management of severe obesity. We included participants who had undergone surgery (gastric bypass, gastric band or sleeve gastrectomy) within 6 months of randomisation. Primary and secondary outcome measures Anxiety and depression were assessed using the Hospital Anxiety and Depression Scale (HADS) at baseline and 12 months post-randomisation. Sociodemographic variables collected at prerandomisation included body mass index, age, sex, ethnicity, marital status, tobacco use, employment status and income band. Results In our sample of 758 participants, 94.5% (n 716) and 93.9% (n 712) had completed baseline anxiety (HADS-A) and depression (HADS-D) subscales. At pre-randomisation 46.1% (n 330/716, 95% CI 42.4% to 49.7%) met clinical case criteria for anxiety and 48.2% (n 343/712, 95% CI 44.5% to 51.8%) for depression. Among participants returning completed 12 months post-randomisation questionnaires (HADS-A n 503/716, HADS-D n 498/712), there was a significant reduction in the proportion of clinical cases with anxiety (?9.5%, 95% CI ?14.3% to -4.8% p<0.001) and depression (?22.3%, 95% CI ?27.0% to ?17.6% p<0.001). Conclusions Almost half of people undergoing bariatric surgery had underlying anxiety or depressive symptoms. In the short term, these symptoms appear to substantially improve. Future work must identify whether these effects are sustained beyond the first post-randomisation year. Trial registration number NCT02841527 and ISRCTN00786323 .

Introduction:
Obesity and common mental disorders, such as anxiety and depression, contribute greatly to global disease burden and pose significant public health challenges. 1–3 There has been a recent focus on understanding the relationship between obesity and common mental disorders. Systematic reviews and meta-analyses of longitudinal studies have found a bidirectional relationship between having obesity and developing a depressive disorder 4 5 across both sexes, however, a recently updated review found an elevated risk only…
