Abstract
Background and objective The aims of this study were to know the prevalence of the psychopathological alterations among patients with morbid obesity (MO) candidates for bariatric surgery in our centre, to analyze its predictive value on the surgical outcome and to study the evolution after weight stabilization was achieved. Patients and methods One hundred and forty five patients of the University Hospital Foundation Alcorcón (122 women) candidates for bariatric surgery (108 finally operated) were included in the study. A clinical interview was carried and several scales of psychopathology were applied before and after surgery: Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), Maudsley Obsessive-compulsive Interview (MOCI), Barrat Impulsiveness Scale (BIS), Eating Disorder Inventory (EDI), Eating Attitudes Test (EAT), Bulimic Investigation Test Edinburg (BITE), and Body Shape Questionnaire (BSQ). A comparison of means between the initial and final scores of the psychometric tests and a logistic regression analysis to identify the predictive variables of positive evolution after surgery (defined as percentage of lost overweight> 50% and final IMC <35) were performed. Results An improvement in the scores of BDI, BAI and in the subscales of EDI, Impulse to the thinness (EDI-DT) and corporal Dissatisfaction (EDI-BD) was observed. The differences were not significant for the rest of the psychometric tests. The multivariate analysis identified 3 predictive factors for postsurgical evolution: BDI (OR 0.91, IC95% 0.82–1.02), BIS (OR 1.08, IC 95% 1.0–1.16) y EDI-DT (OR 1.18, IC 95% 1.0–1.39). Conclusions In our study, the scales of depression, anxiety, impulse to thinness and corporal dissatisfaction improved in patients with MO after bariatric surgery. Some baseline psychometric variables may predict a favourable postsurgical evolution of these patients.
