Psychiatric Comorbidities Associated with Food Addiction in Post-Bariatric Patients: Toward Personalized Mental Health Screening and Postoperative Care

<b>Background:</b> Food addiction (FA) is an emerging construct that mirrors the behavioral and neurobiological characteristics of substance use disorders. Despite growing interest, its association with specific psychiatric disorders among bariatric patients remains understudied. <b>Objective:</b> Our aim was to examine the prevalence and strength of associations between FA and seven major psychiatric disorders in individuals who underwent bariatric surgery. <b>Methods:</b> In a sample of 100 post-bariatric patients referred for psychiatric evaluation, FA was assessed using the modified Yale Food Addiction Scale 2.0 (mYFAS 2.0), and psychiatric disorders were diagnosed using the Mini International Neuropsychiatric Interview (MINI). Logistic regression models were used to estimate adjusted odds ratios (aORs) for the association between FA and each psychiatric disorder, controlling for sex, age, body mass index (BMI), employment status, the number of children, clinical comorbidities, physical activity, family psychiatric history, and region of residence. <b>Results:</b> FA was present in 51% of the sample. Descriptive analyses revealed a significantly higher prevalence of major depressive disorder, panic disorder, generalized anxiety disorder, social anxiety disorder, agoraphobia, obsessive-compulsive disorder, and bulimia nervosa among individuals with FA. Multivariate models showed robust associations between FA and bulimia nervosa (aOR = 19.42, <i>p</i> < 0.05), generalized anxiety disorder (aOR = 2.88, <i>p</i> < 0.05), obsessive-compulsive disorder (aOR = 6.64, <i>p</i> < 0.05), agoraphobia (aOR = 3.14, <i>p</i> < 0.05), social anxiety disorder (aOR = 4.28, <i>p</i> < 0.05) and major depressive disorder (aOR = 2.79, p < 0.05). <b>Conclusions:</b> FA is strongly associated with a range of psychiatric comorbidities in post-bariatric patients, reinforcing the need for comprehensive mental health screening in this population. These findings underscore the potential role of FA as a clinical marker for stratified risk assessment, supporting more personalized approaches to mental health monitoring and intervention following bariatric surgery.
