This study aims to evaluate sociodemographic variables, psychiatric comorbidities, emotional dysregulation, executive functions and affective temperaments in obese bariatric patients. A second objective is to explore the differences in these dimensions between obese patients and a control group of normal-weight healthy controls, as well as between BED and NBED obese patients. Thirty-eight obese patients (BMI ≥ 35), candidates for bariatric surgery, were consecutively enrolled at the Obesity Center of Endocrinology Unit 1. In a single consultation, socio-demographic and clinical variables were recorded and psychometric scales assessing temperamental characteristics, emotional regulation and impulsivity were administered to the patients. An age- and sex-matched control group of 75 non-obese subjects (18,5 ≤ BMI < 30) was also recruited through a web-based survey. Compared to control subjects, obese patients showed a lower level of education and employment and a higher level of non-planning impulsivity. Obese patients presenting a diagnosis of BED (53%) showed higher rates of emotional dysregulation, cyclothymic temperament and family history for suicide compared to non-BED patients. Our data are in agreement with the extant literature as regards sociodemographic and socioeconomic indicators associated with obesity, including lower educational levels, higher frequency of married civil state and unemployment. Our results seem to confirm that obese people commonly exhibit greater impulsivity with respect to the general population, and that BED-comorbid obesity is associated with more severe psychiatric comorbidity, emotional dysregulation and impulsivity by comparison with N-BED obesity.
