Objective: This study aims to investigate: (a) the association of eating disorders with childhood sexual abuse and recent stressful life events; (b) the coexistence of eating disorders and other common psychiatric disorders; and (c) the impact of eating disorders on obesity, medical conditions, and health service utilization. Method: We conducted secondary data analyses based on population-based study, which consists of a nationally representative sample of 2,870 community-dwelling adults aged 50 and above, interviewed in 2006 to 2007. Results and conclusion: The 12-month prevalence of eating disorders was 2.61%. Multivariate analyses revealed that eating disorders were more common among younger age groups, women, and those who reported stressful life events. In addition, eating disorders were significantly related to anxiety disorders, agoraphobia, panic disorder, obesity, and cancer. Discussion: This study supports the notion that eating disorders in older adults are associated with a number of psychosocial, psychiatric, and medical conditions.
