Hi! I am trying to compare the prevalence of Eating Disorders (including anorexia, bulimia, binge eating) of athletes to general population.
1) I know that the prevalence of anorexia, bulimia, and binge eating in general population is 0.3%, 0.9%, 1.6% respectively.
2) I also know that the prevalence of Eating disorders (which already combined anorexia, bulimia, and binge eating) in athletes is 28%.
How do I combine the prevalences of anorexia, bulimia, and binge eating in general population so I can compare it to the athletes?
