There are limited data on the epidemiology of eating disorders (ED) in migrants. Recent Scandinavian research suggests that migrants are at lower risk of eating disorders, however, to our knowledge there have not been comparable studies exploring eating disorders in Australian adult populations. We sought to explore the prevalence of EDs in first-generation migrants to Australia in comparison with the Australian-born population. A secondary aim was to explore ED prevalence across first-generation migrants from different regions of birth (Europe, Asia, Africa, and Other).
