The prevalence of psychological disorders in bariatric surgery candidates is well established, where anxiety and depression are commonly observed. Depression prevalence and evolution after gastric bypass, and its impact on weight loss, have been less explored, especially among low-income patients.
A retrospective study with low-income patients undergoing bariatric surgery from 2015 to 2016. A comparative analysis of preoperative depression (the Beck Depression Inventory II) was performed and compared at 6 and 12 months. A demographic and weight loss analysis was also performed.
Seventy-three patients were included. Female sex comprised 76.7% of cases, and baseline depression was present in 45.2%, being severe in 2.7%. The analysis at 6 months showed Beck's score improvement (12.3 baseline vs. 4.2 points at 6 months, p = 0.006), as well as for individual items (excepting irritability). At 12 months, the mean score was 5 points, without difference vs. 6 months. At 6 and 12 months, depression (any degree) was present in 9.6 and 8.6%, corresponding to percentage change rates of - 65.8 and - 59.3%. Only one patient (2.7%) presented severe depression. Depression status before surgery had no influence in weight loss amount at 12 months.
Almost half of bariatric surgery candidates have some degree of depression that improves dramatically soon after bariatric surgery. Such change continues stable during the first year. Improvement was independent of gender, and depression has no influence on weight loss. In low-income bariatric patients, depression is lower than reports from developed countries, but similar improvement has been observed.
减重手术候选人中心理障碍的患病率很高，其中焦虑和抑郁较为常见。胃旁路术后抑郁的患病率和演变，及其对体重减轻的影响，研究得较少，尤其是在低收入患者中。
这是一项回顾性研究，纳入了 2015 年至 2016 年期间接受减重手术的低收入患者。对术前抑郁（贝克抑郁量表 II）进行了比较分析，并在 6 个月和 12 个月时进行了比较。还进行了人口统计学和体重减轻分析。
共纳入 73 例患者。女性占 76.7%，基线时存在抑郁的患者占 45.2%，重度抑郁的患者占 2.7%。6 个月时分析显示贝克评分有所改善（基线时为 12.3 分，6 个月时为 4.2 分，p=0.006），个别项目（除易怒外）也是如此。12 个月时，平均得分为 5 分，与 6 个月时无差异。6 个月和 12 个月时，任何程度的抑郁分别为 9.6%和 8.6%，相应的百分比变化率为-65.8%和-59.3%。仅 1 例患者（2.7%）患有重度抑郁。术前抑郁状态对 12 个月时的体重减轻量无影响。
近一半的减重手术候选者存在一定程度的抑郁，这种抑郁在减重手术后很快会显著改善。这种变化在第一年期间保持稳定。改善与性别无关，且抑郁对体重减轻没有影响。在低收入的减重患者中，抑郁的发生率低于发达国家的报告，但观察到了相似的改善。
