Abstract

Background: Past research suggests self-harm/suicidality are more common among adults who have undergone bariatric surgery than the general population. Objectives: To compare prevalence of self-harm/suicidal ideation over time and identify presurgery risk factors for postsurgery self-harm/suicidal ideation. Setting: The Longitudinal Assessment of Bariatric Surgery-2 is a cohort study with presurgery and annual postsurgery assessments conducted at 10 U.S. hospitals. Methods: Adults with severe obesity undergoing bariatric surgery between March 2006 and April 2009 (n = 2458). Five-year follow-up is reported. Self-reported history of suicidality assessed retrospectively via the Suicide Behavior Questionnaire-Revised (SBQ-R) and self-reported self-harm/suicidal ideation assessed prospectively via the Beck Depression Inventory-Version 1 (BDI-1). Results: The SBQ-R was completed by 1540 participants; 2217 completed the BDI-1 pre- and postsurgery. Over 75% of participants were female, with a median age of 46 years and body mass index of 45.9 kg/m2. Approximately one fourth of participants (395/1534) reported a presurgery history of suicidal thoughts or behavior (SBQ-R). The prevalence of self-harm/suicidal ideation (BDI-1) was 5.3% (95% confidence interval [CI], 3.7–6.8) presurgery and 3.8% (95% CI, 2.5–5.1) at year 1 postsurgery (P =.06). Prevalence increased over time postsurgery to 6.6% (95% CI, 4.6–8.6) at year 5 (P =.001) but was not significantly different than presurgery (P =.12). Conclusions: A large cohort of adults with severe obesity who underwent bariatric surgery had a prevalence of self-harm/suicidal ideation that may have decreased in the first postoperative year but increased over time to presurgery levels, suggesting screening for self-harm/suicidality is warranted throughout long-term postoperative care. Several risk factors were identified that may help with enhanced monitoring.
