Abstract
BackgroundFew studies have investigated the epidemiology of eating disorders using national representative data. In this study, we investigated the treatment prevalence and economic burden of eating disorders in South Korea.MethodsThe aim of this study was to estimate the treatment prevalence and the medical expenditure of diagnosed eating disorders (ICD F50.x) in South Korea between 2010 and 2015. We also examined the economic costs of eating disorders, including the direct medical cost, direct non-medical costs, and indirect costs, in order to calculate the economic burden of such disorders.ResultsThe total treatment prevalence of eating disorders in South Korea was 12.02 people (per 100,000) in 2010, and 13.28 in 2015. The cost of medical expenditures due to eating disorders increased from USD 1229724 in 2010 to USD 1843706 in 2015. The total economic cost of eating disorders was USD 5455626 in 2015. In 2015, the economic cost and prevalence of eating disorders was the highest in the 20–29 age group.ConclusionsThe results showed the eating disorders are insufficiently managed in the medical insurance system. Further research is therefore warranted to better understand the economic burdens of each type of eating disorder.
Highlights
Few studies have investigated the epidemiology of eating disorders using national representative data
Plain English summary This article is the result of estimating the overall medical expenditures due to eating disorders in South Korea, a country that has introduced the National Health Insurance system, the prevalence rate based on this, and further the economic burden
The economic cost of eating disorders was derived from the data of the National Health Insurance Services (NHIS), which is the single insurer in South Korea [23]
Summary
Few studies have investigated the epidemiology of eating disorders using national representative data. We investigated the treatment prevalence and economic burden of eating disorders in South Korea. Even when eating disorders are treated, medication has limited efficacy and, in general, more than half the patients with anorexia and bulimia nervosa do not recover fully [1, 6]. The quality of life for patients with eating disorders deteriorates more than it does for patients with symptomatic coronary heart disease or major depression, and the duration of illness tends to be longer [14]. The socio-economic burden and costs of anorexia nervosa and bulimia nervosa are similar to those of anxiety disorders and depression [6], as quantified by the Global Burden of Disease Study conducted in 2013 [17]
