MedicalResearch.com: What is the background for this study?
Response: The National Epidemiologic Survey on Alcohol and Related Conditions III (NESARC III) was the largest epidemiological study on psychiatric disorders in US non-institutionalized adults that was conducted by the National Institution on Alcohol Abuse and Alcoholism, and the first one sinceDSM-5 came out. The last population-based study with US adults that examined eating disorders was the National Comorbidity Survey-Replication Study conducted by Hudson and his colleagues and published in 2007.
We felt that it was important to obtain new prevalence estimates in a larger and representative sample especially because the DSM-5 included several changes to the criteria for eating disorders from the earlier DSM-IV. Thus, we thought it was important to provide updated and new prevalence estimates for eating disorders as well as how they are distributed across sex, ethnicity/race, and age. Many researchers and clinicians expected higher estimates than earlier studies as a result of “loosening” of diagnostic criteria for eating disorders.
