Epidemiology of eating disorders: population, prevalence, disease burden and quality of life informing public policy in Australia—a rapid review

Abstract

Plain English summary Our understanding of the prevalence and impact of eating disorders has improved significantly over the past 20-years. Research highlights that rates of eating disorders are increasing. To inform the development of the Eating Disorder Research and Translation Strategy 2021–2031 this review aimed to better understand the global change in prevalence and impact of eating disorders to inform policy decision-making. Three scholarly databases were systematically searched for related research published between 2009 and 2021. Searches identified 135 studies which met our inclusion criteria. Estimates in lifetime eating disorder prevalence varied from 2.58 to 8.4% in women and girls. Findings indicated that eating disorders appeared more prevalent in young people and adolescents, particularly young women, while sexuality diverse (LGBTQI +) individuals were six-times more likely to have an eating disorder compared to the general male population. The little research suggests moderate to high prevalence of eating disorders in First Australian peoples, Australia’s spending on eating disorders was estimated at ~ $84 billion due to disability or death. There is no doubt that eating disorder prevalence and impact are on the rise. Future research should include more diverse populations to increase estimate accuracy and improve care for all.
