Relationship of personality characteristics and eating attitude with the success of bariatric surgery

Obesity is a chronic disease that causes several medical and psychiatric complications. There are plenty of pharmacological and non-pharmacological therapies for obesity treatment. Bariatric surgery is one of the most efficient non-pharmacological treatment for morbid obesity; however, several psychological factors affect the success of bariatric surgery. This study aims to evaluate personality characteristics and eating attitude relationship with the success of bariatric surgery.

This study was carried out on 75 patients with obesity who were candidates of bariatric surgery in the obesity clinic of Rasoul-e-Akram Hospital in Tehran. The patients were asked to fill the TCI and EAT-26 questionnaires before and after the surgery. Statistical analyses were performed using the SPSS-23 applying T-test, Mann-Whitney tests and Pearson and Spearmanchr('39')s correlation coefficient. The significance level was set at 0.05.

Seventy-five patients, including 13 men and 62 women, were assessed through this study. The mean of the BMI of the participants was 44.7 prior to the surgery and 30 after the operation. Personality characteristics and eating attitudes had no significant relationship with the success of bariatric surgery.

Although the eating attitude and personal characteristics of the bariatric surgery candidates before the surgery was not related to the outcome of the surgery, they should be considered in post-operational psychological assessments.
