Abstract

BACKGROUND:

Morbid obesity is associated with debilitating psychosocial consequences, such as depression, anxiety, and low self-esteem. One of the main goals of bariatric surgery should not only be reducing weight and counteracting co-morbid conditions, but also improving postoperative psychosocial functioning. The objective of our study was to determine the preoperative variables that could predict the psychological symptoms 6 and 12 months after surgery to improve the clinical outcome of morbidly obese patients undergoing bariatric surgery. The setting was a university hospital in Spain.

METHODS:

The study group consisted of 60 morbidly obese patients (46 women and 14 men) who had undergone gastric bypass surgery for weight reduction and had ≥ 1 year of follow-up. The patients were evaluated using different questionnaires (Symptom Checklist-90-Revised, Body Shape Questionnaire, Rosenberg Self-Esteem Questionnaire, COPE, Medical Outcomes Study Social Support Survey) at 3 points: before surgery, at 6 months postoperatively, and at 1 year postoperatively. To determine the influence of preoperative variables on long-term psychological status, a step-by-step multivariate linear regression analysis was performed, taking P < .05 as statistically significant.

RESULTS:

The variables of self-esteem, instrumental support, and coping focused in the emotions were the main preoperative predictors for psychological symptoms 6 months after surgery. Preoperative drug abuse as a strategy of problem solving and mainly body image significantly predicted most of the psychological disorders 1 year after surgery.

CONCLUSION:

The study of different psychosocial variables in patients before bariatric surgery is an important aid to predict postoperative psychological functioning. Self-esteem and body image were the most influential factors in the postoperative psychological outcome of morbidly obese patients in our study.
