Background:Bariatric surgery (BS) is an effective therapy for those who are excessively obese. However, the consequences of surgery on mental health are still debatable. We aimed to investigate the patients’ depression, stress, and anxiety levels before and after BS at two different times: just before surgery and 12 months later.Methods:This is a repeated cross-sectional study. The Depression Anxiety Stress Scale (DASS-21) was used to assess depression, anxiety, and stress levels.Results:There were 288 participants in the BS groups. Changes in anxiety, stress, and depressive symptoms over time were examined using generalised estimating equations models with repeated measurements per individual. Anxiety (incidence rate ratio [ IRR] = 1.2, p < .001) and stress (IRR = 0.86, p < .001) worsened, whereas depression ( IRR = –1.8, p < .001) improved significantly in 288 patients one year after BS.Conclusions:BS had significant impacts on obesity-associated mental health issues.

减肥手术前和术后十二个月的压力、焦虑和抑郁：重复横断面研究

背景：减肥手术（BS）是治疗过度肥胖者的有效疗法。然而，手术对心理健康的影响仍然存在争议。我们旨在调查 BS 前后两个不同时间患者的抑郁、压力和焦虑水平：手术前和 12 个月后。方法：这是一项重复的横断面研究。使用抑郁焦虑压力量表（DASS-21）来评估抑郁、焦虑和压力水平。结果：BS 组有 288 名参与者。使用广义估计方程模型对每个人进行重复测量来检查焦虑、压力和抑郁症状随时间的变化。一年内 288 名患者的焦虑（发生率比 [IRR] = 1.2，p < .001）和压力（IRR = 0.86，p < .001）恶化，而抑郁症（IRR = –1.8，p < .001）显着改善结论：BS 对肥胖相关的心理健康问题有显着影响。
