BACKGROUND: Binge-eating disorder may represent a risk factor for the metabolic syndrome. OBJECTIVE: The objective was to assess longitudinally the relation between binge-eating disorder and components of the metabolic syndrome. DESIGN: At 2.5 and 5 y of follow-up, 134 individuals with binge-eating disorder and 134 individuals with no history of eating disorders, who were frequency-matched for age, sex, and baseline body mass index (BMI), were interviewed during the follow-up interval regarding new diagnoses of 3 metabolic syndrome components: hypertension, dyslipidemia, and type 2 diabetes. RESULTS: A comparison of individuals with and without a binge-eating disorder in analyses adjusted for age, sex, baseline BMI, and interval BMI change had hazard ratios (95% CIs) for reporting new diagnoses of metabolic syndrome components of 2.2 (1.2, 4.2; P = 0.023) for dyslipidemia, 1.5 (0.76, 2.9; P = 0.33) for hypertension, 1.6 (0.77, 3.9; P = 0.29) for type 2 diabetes, 1.7 (1.1, 2.6; P = 0.023) for any component, and 2.4 (1.1, 5.7; P = 0.038) for ≥2 components. CONCLUSION: Binge-eating disorder may confer a risk of components of the metabolic syndrome over and above the risk attributable to obesity alone.
