Association of binge eating behavior and psychiatric comorbidity in ELSA-Brasil study: Results from baseline data

Abstract

ObjectiveTo estimate the association of binge eating behavior (BE) with common mental disorders (CMD). MethodCross sectional investigation of 14,088 adults, aged 35–74years (ELSA-Brasil study). BE was assessed with Structured Clinical Interview for DSM Disorders (SCID – DSM IV) questions, and psychiatric morbidity with CIS-R (CIS R – Clinical Interview Schedule Revised). Poisson regression was used to estimate the association of BE and psychiatric morbidity. ResultsAdjusted prevalence ratios (PR) for CMD and BE were: PR=1.60 (1.34–1.91) for a CIS R score 12–18 (presence of CMD with lower clinical severity); PR=2.40 (2.06–2.80) for a CIS R score≥18 (severe symptom profile likely to require treatment); for psychiatric diagnoses: PR=2.24 (1.84–2.73) for depressive episodes; PR=1.77 (1.53–2.04) for anxiety disorders, and PR=1.42 (1.20–1.67) for mixed depressive-anxiety disorder. ConclusionBE was associated with higher prevalence of common mental disorders. Our findings highlight the need to investigate mechanisms involved in the relationship of BE, obesity and psychopathology in low/middle income countries.
