Background: Patients with obesity seeking bariatric surgery often display high rates of depressive symptoms, which are linked to worse clinical and surgical outcomes. A comprehensive evaluation of depression-related features in this population is lacking. Therefore, this study investigated clinical and psychopathological factors associated with depressive symptoms’ severity in 946 outpatients with obesity undergoing pre-surgical evaluation.
Methods: The sample (45.1 ± 12 years) was subdivided according to Patient Health Questionnaire-9 (PHQ-9) into ‘absent’, ‘mild’, and ‘moderate-to-severe depression’ groups, which were compared for sociodemographic characteristics, childhood trauma, and emotional dysregulation. Assessments included the Childhood Trauma Questionnaire-Short-Form (CTQ-SF) and Difficulties in Emotion Regulation Scales (DERS). Inflammatory levels were evaluated through the Systemic Immune-inflammatory Index (SII). Multinomial logistic regression and correlations were performed to evaluate predictors of depression severity and their interrelationship.
Results: Beyond sociodemographic and clinical differences, patients with moderate-to-severe depression displayed higher childhood trauma, emotional dysregulation, and inflammatory levels. Logistic regression with 95% confidence intervals showed that higher CTQ-SF scores were significantly associated with moderate-to-severe vs. absent depression (
p = 0.005, 95% CI: 1.02–1.09), while elevated DERS scores were a risk factor for both moderate-to-severe vs. mild (
p < 0.001, 95% CI: 1.04–1.11) and vs. absent depression (
p < 0.001, 95% CI: 1.11–1.18). Additionally, PHQ-9 was significantly correlated with CTQ-SF, DERS, and SII.
Conclusions: A worse clinical picture was observed in patients with moderate-to-severe depression, and significant interactions were found between psychopathology and inflammatory indexes. Emotional dysregulation was primarily associated with depression severity. These preliminary results support the implementation of rigorous pre-operative screening to identify and deliver targeted psychotherapeutic/pharmacological interventions aimed at improving clinical and post-surgical outcomes.
