Abstract

Aim: Determination of psychopathological factors before bariatric surgery has an important role in successful weight loss and in maintaining this weight loss after surgery. The purpose of this study was to evaluate depression, anxiety, temperament and sociodemographic characteristics that may affect weight loss after bariatric surgery.

Methods: A total of 94 patients with morbid obesity who underwent bariatric surgery between 2013 and 2016 were followed-up for one year. Pre-operative sociodemographic characteristics, binge eating and family history of obesity were determined. In addition, the Memphis, Pisa, Paris and San-Diego Auto-questionnaire (TEMPS-A) for temperament characteristics, the Beck Depression inventory and the Beck Anxiety Inventory were applied.

Results: 94 morbidly obese patients were included in the study. 23(22.8%) of the patients had failed to lose weight [Excess weight loss (EWL) <50%] after 12 months. Participants who had obese siblings (X2 = 4.145, p = 0.042) and clinically significant depressive symptoms (X2 = 4.446, p = 0.035) showed failure to lose weight. According to BDI, it was found that the depressive, cyclothymic, irritable and anxious temperament characteristics of the participants with depression differed significantly compared to those without (respectively; t = 6.46, p = <0.001; t = 5.59, p = <0.001; t = 4.83, p = 0.001, respectively; t = 5.06, p = <0.001).

Conclusions: It may be important to determine the individuals who have depressive disorder before bariatric surgery and to include practices related to temperament characteristics in their follow-up and treatment. It may be useful to train eating habits and to follow diet programs more closely for those who have obesity among their siblings.
