The study found high rates of mental disorders, particularly mood and eating disorders, among obese patients seeking bariatric surgery. Comparative results showed significant differences in psychiatric comorbidities, temperaments, emotional dysregulation, and impulsivity between obese patients with and without mood disorders.
Background: Obese patients seeking bariatric surgery are known to show high rates of mental disorders, mainly mood and eating disorders. The aim of the present study is to evaluate psychiatric comorbidities, affective temperamental dimensions, emotional dysregulation and impulsivity in a sample of obese bariatric patients, exploring the differences between obese patients with and without mood disorders (MD). Methods: A total of 69 obese patients were consecutively enrolled between March and November 2019 during the presurgical evaluation routinely performed before the bariatric intervention. Sociodemographic and clinical features were collected by psychiatrists during a single consultation. Affective temperaments, emotional dysregulation and impulsivity were also investigated through self-report questionnaires. Epidemiological and clinical variables were compared between patients with and without MD. Results: In our sample, almost 3 out of 4 patients presented a lifetime psychiatric disorder, mainly MD (n=33, 48%), binge eating disorder (BED) (n=34, 49%) and anxiety disorders (n=30, 43%). Compared to N-MD patients, those with MD showed higher rates of psychiatric comorbidity with BED, bulimia and panic disorder. In addition, obese patients with MD showed more frequently cyclothymic, depressive and anxious temperaments, and higher mean scores on the psychometric questionnaires assessing emotional dysregulation and impulsivity compared to obese subjects without MD. Limitations: the small sample size, the retrospectively assessment of psychiatric disorders and the self-report questionnaires. Conclusions: A subgroup of obese patients, especially among those with MD, show high emotional dysregulation, affective lability and impulsiveness that could represent suitable substrates for the development of compulsive and addictive eating habits.
