Background: Little population-based data exist in the United Sates on the epidemiology of racial/ethnic influences on the development of binge eating disorder. Cross-national data on BED are presented and compared among period prevalence and lifetime prevalence groups using the Collaborative Psychiatric Epidemiology Surveys.

Methods: Cross-sectional survey data generated from the 2001-2003 Collaborative Psychiatric Epidemiology Surveys (CPES) were used in this study. CPES contains three national representative surveys: the National Comorbidity Survey Replication (NCS-R), the National Survey of American Life (NSAL), and the National Latino Asian American Study (NLAAS). The survey population includes all United Sates adults who are 18 years of age and older residing in housing located in one of the 48 contiguous states.

Results: Racial/Ethnic-specific prevalence estimates are consistently higher within 12-Month and Lifetime BED groups. Crude estimates show Hispanic/Latin-American survey respondents as having a higher odds of endorsing 12-Month (OR: 1.85, 95%CI: 1.06 - 3.24) binge eating disorder compared to Caucasians. Additionally, adjusted estimate reports reveal a decreased odds of both 12-Month and Lifetime BED when assessing the effect of immigration status on the racial/ethnic category called "other".

Conclusion: BED represents a public health problem greater than other eating disorders such as Anorexia and Bulimia Nervosa, with slight differences among persons of different cultural/racial groups. New and updated DSM-V BED guidelines exist that can guide research and highlight the clinical importance of diagnosing and treating patients with BED and other health problems.
