Depressive symptoms before and after abdominoplasty among post-bariatric patients – a cohort study

Abstract

Abstract The majority of post-bariatric patients suffer from excess skin after weight loss, impairing physical, psychosocial and mental health. The abdomen is the most common location for excess skin, and abdominoplasty is the most commonly required reconstructive procedure. Abdominoplasty removes excess abdominal skin and attenuates related symptoms, but knowledge regarding mental health-related effects is scarce. Here, we aimed to evaluate the symptoms and severity of depression before and after abdominoplasty in post-bariatric patients and to analyse the relationships between depressive symptoms, quality of life (QoL) and experience of excess skin. We enrolled 110 former obese patients undergoing abdominoplasty. Three questionnaires evaluating the symptoms of depression (Beck Depression Inventory (BDI-II)), experience of excess skin (Sahlgrenska Excess Skin Questionnaire (SESQ)) and QoL (36-item Short-Form Health Survey (SF-36)) were completed preoperatively and 1year postoperatively. After abdominoplasty, symptoms of depression (BDI sum score) significantly decreased (5.8 vs. 3.0, p = .037). Scores on three BDI questions improved (p < .05), and the SESQ score normalised (p < .001), while the SF-36 score was unaffected. The BDI sum score was moderately correlated with the SF-36 mental composite score (preoperatively, rs = −0.69; postoperatively, rs = −0.66) and fairly correlated with the SF-36 physical composite score (rs = 0.32, rs = 0.26). The correlation between the BDI sum and SESQ scores was poor preoperatively (rs = −0.106) and fair postoperatively (rs = 0.232). The results indicate that abdominoplasty may reduce symptoms of depression in post-bariatric patients. However, the procedure did not affect SF-36 scores. Further studies are required to validate these results.
