Evolution of depressive symptoms from before to 24 months after bariatric surgery: A systematic review and meta‐analysis

“…Higher preoperative depressive symptom scores were associated with larger decreases to scores postoperatively, which is consistent with previous meta-analyses examining psychological and pharmacological interventions 18,35 and suggests large improvements to the quality of life among those initially more impaired. 2 Despite higher preoperative depressive symptom scores being associated with larger reductions, postoperative depression values might continue to be above questionnaire thresholds that are indicative of clinical depression.…”

“…Decreased depressive symptom scores at 6 and 12 months did not differ by the type of bariatric procedure. This aligns with most reports of depression outcomes by surgery type 18,21,74,75 . Murphy et al 76 observed larger decreases to depressive symptom scores initially if having undergone gastric bypass compared to gastric banding, but these differences between procedures were negligible 24 months after surgery.…”

“…This aligns with most reports of depression outcomes by surgery type. 18,21,74,75 Murphy et al 76 observed larger decreases to depressive symptom scores initially if having undergone gastric bypass compared to gastric banding, but these differences between procedures were negligible 24 months after surgery. Considering that specific procedures are recommended according to obesity severity 77 and presences of other comorbidities, 78 these results suggest similar favorable psychological outcomes irrespective of the type of procedure received.…”

Prevalence and Outcomes of Depression After Bariatric Surgery: A Systematic Review and Meta-Analysis

“…Pooling the data revealed a prevalence rate of 15.3% (95% CI: 15.0-15.5%, p<0.001) (Figure 3) [10,16,32,33,[36][37][38][39][40][42][43][44][45][46][47][48][49][51][52][53][54][55][56][57][58]60,61]. Subgroup analysis among patients with depression revealed that prevalence of severe depression was 1.9% (95% CI: 1.5-2.4%, p<0.001).…”

“…Subgroup analysis among patients with depression revealed that prevalence of severe depression was 1.9% (95% CI: 1.5-2.4%, p<0.001). The prevalence of moderate depression was 5.1% (95% CI: 4.4-5.8%, p<0.001), whereas the prevalence of mild and minimal depression was 12.7% (95% CI: 11.8-13.7%, p<0.001), and 64.9% (95% CI: 63.3-66.5%, p<0.001) (Figure 4, panels A-D) [33,41,43,47,55,57,60].…”
