Introduction: Binge eating is often associated with multiple comorbidities, including obesity, metabolic disorders, and cardiovascular diseases, which often cause functional impairment and impose a substantial burden on health. Objective: To analyze the epidemiological profile of binge eating disorder (BED), bulimia nervosa (BN) and any binge eating disorders or behaviors (ABEDB) in a representative sample of the adult population living in the Metropolitan Region of São Paulo, Brazil. Methods: A crosssectional population-based study was conducted with a representative sample of adults living in the Metropolitan Region of São Paulo, Brazil (n=2,942). The CIDI 3.0 diagnostic interview was used to determine estimates of lifetime, 12-month and 30-day prevalence of BN, BED and ABEDB defined by DSM-IV criteria, in addition to sociodemographic data, self-reported anthropometric measures and chronic health conditions, including rheumatologic diseases, chronic pain, hypertension and cardiovascular diseases, chronic lung disease, diabetes or glucose intolerance and gastrointestinal ulcer. Statistical analysis employed cross-tabulations to assess prevalence distributions across sociodemographic variables and comorbidity with chronic conditions and overweight. Bivariate analyses and Poisson regression models adjusted for sex and age (Stata 17.0) evaluated associations, with significance of p< 0.05. Results: Lifetime, 12-month and 30- day prevalence estimates were, respectively, 2.0% (SE 0.3), 0.9% (SE 0.2) and 0.4% (SE 0.1) for BN; 4.7% (SE 0.3), 1.8% (SE 0.3) and 1.2% (SE 0.2) for BED; and 9.0% (SE 0.5), 3.4% (SE 0.4) and 2.0% (SE 0.3) for ABEDB. Women had higher prevalences of binge eating disorders and behaviors. The lifetime prevalence of ABEDB was higher among younger cohorts. No significant differences were observed in the distributions according to marital status, education or income. Lifetime prevalence of BN was higher among individuals with gastrointestinal ulcer (8.2%, SE 2.8, PR 5.2), headache (3.5%, SE 0.6, PR 2.3), cervical/lumbar pain (3.3%, SE 0.6, PR 2.1), and hypertension (3.1%, SE 0.7, PR 2.5). Lifetime prevalence of BED was higher among those with chronic lung disease (13.2%, SE 6.0, PR 3.3), arthritis/rheumatism (10.0%, SE 2.1, PR 2.8), gastrointestinal ulcer (9.2%, SE 2.6), cervical/lumbar pain (8.9%, SE 1.3) and other chronic pain (7.7%, SE 1.2, PR 1.8). Lifetime prevalence of ABEDB was higher among respondents who reported gastrointestinal ulcer (18.1%, SE 3.1, PR 2.5), cervical/lumbar pain (14.0%, SE 1.9, PR 2.0), headaches (12.8%, SE 1.2, PR 1.5), and other chronic pain (11.7%, SE 1.5, PR 1.4). Prevalence estimates of binge eating disorders and behaviors were also elevated among individuals in higher BMI categories. Conclusion: Binge eating disorders and behaviors are highly prevalent in the population studied, especially among women (11.2%; SE 0.92) and have high comorbidity with overweight, obesity and different chronic conditions, including metabolic and cardiovascular diseases, and other conditions such as chronic pain, rheumatologic diseases, and gastrointestinal ulcers.
