Not mutually exclusive. Counts are limited to diagnoses performed at the first day of a recorded diagnosis of an eating disorder (i.e., more than one diagnosis can be recorded at the same day). ICD‐10‐CM codes were used to identify forms of EDs. The F50.1 and F50.2 codes were used to define anorexia nervosa and bulimia nervosa, respectively. Conditions classified under the F50.8 diagnostic code were considered as other eating disorders, and included binge eating disorder and avoidant restrictive food intake disorder, among others. Conditions classified under the F50.9 diagnostic code were considered as unspecified eating disorders.
Rural was included as a category since theindex cannot be calculated for people living in rural areas.
