Pre- and postoperative psychological characteristics in morbidly obese patients.
BACKGROUND
Quality of life is poor in morbidly obese patients, because of impaired physical and psychosocial functioning. Surgical treatment offers long-term weight reduction and amelioration of most associated comorbidities. Studies of the effect of weight loss on patients' mental well-being are required, because discrimination and psychopathologic consequences represent a heavy burden.


METHODS
53 patients were interviewed 48 hours before vertical banded gastroplasty (VBG) by the psychiatric team and completed the self-administered SCL-90-R questionnaire. Correlations of patients' age, educational level, employment, duration of obesity and family conditions were investigated and compared with the degree of obesity 10-12 months postoperatively. 35 patients returned to psychiatric follow-up and completed the same questionnaire, and the various psychopathologic characteristics were compared to the preoperative ones.


RESULTS
Females had statistically significant higher scores in all psychopathologic parameters studied; more obvious differences were seen in depression (P < 0.001), paranoid ideation (P < 0.001) and interpersonal sensitivity (P < 0.001). Correlations of several demographic characteristics with the patients' preoperative BMI were negative. 10-12 months following VBG, statistically significant improvement in the parameters of phobic anxiety, obsessions-compulsions, paranoid ideation and interpersonal sensitivity (P < 0.05) were found.


CONCLUSIONS
Pre-existing psychopathology was more obvious among females, and improved significantly following successful weight loss 1 year postoperatively.
