Epidemiology

United States

 * In the general population, lifetime prevalence for BED ranges from 1.1 to 1.9 percent.
 * One literature review found that point prevalence rates for BED vary from 0.1 percent to 24.1 percent depending on the sample. This same review also found that the 12-month prevalence rates vary between 0.1 percent to 8.8 percent.
 * BED cases usually occur between the ages of 12.4 and 24.7, but prevalence rates increase until the age of 40.
 * Lifetime prevalence rates for BED in women is anywhere from 1.5 to 6 times higher than in men.
 * Due to limited and inconsistent information and research on ethnic and racial differences, prevalence rates are hard to determine for BED. One literature review found information citing no difference between BED prevalence among Hispanic, African American, and White women while other information found that BED prevalence was highest among Hispanics followed by Black individuals and finally White people.

Worldwide

 * The worldwide prevalence of BED is around 0.9 percent with women reporting significantly higher rates than men from 1.4 percent in women to 0.4 percent in men. There was not a significant difference between prevalence rates of BED in low-, middle-, and high-income countries.
 * Eating disorders have usually been considered something that was specific to Western countries. However, the prevalence of eating disorders is increasing in other non-Western countries.

Nordic Countries

 * The prevalence of BED is lower in Nordic countries compared to Europe in a study that included Finland, Sweden, Norway, and Iceland. The point prevalence ranged from 0.4 to 1.5 percent and the lifetime prevalence ranged from 0.7 to 5.8 percent for BED in women.

Latin American Countries

 * In a study that included Argentina, Brazil, Chile, Colombia, Mexico, and Venezuela, the point prevalence for BED was 3.53 percent. Therefore, this particular study found that the prevalence for BED is higher in these Latin American countries compared to Western countries.

European Countries

 * The prevalence of BED in Europe ranges from <1 to 4 percent.

Underreporting in men
Eating disorders are oftentimes underreported in men. Underreporting could be a result of measurement bias due to how eating disorders are defined. The current definition for eating disorders focuses on thinness. However, eating disorders in men tend to center on muscularity and would therefore warrant a need for a different measurement definition. Further research should focus on including more men in samples since previous research has focused primarily on women.

Co-morbidity
BED is co-morbid with diabetes, hypertension, previous stroke, and heart disease in some individuals.

In people who have obsessive-compulsive disorder or bipolar I or II disorders, BED lifetime prevalence was found to be higher.
