Abstract
BACKGROUND
Eating disorders (EDs) have increasingly become a public health problem globally, especially among children and adolescents.
AIM
To estimate the burden of EDs in children and adolescents (ages 5-19 years) at the global, regional, and national levels.
METHODS
Retrieved from Global Burden of Disease Study 2019 for EDs, including anorexia nervosa and bulimia nervosa, we extracted the disability-adjusted life years (DALYs) and prevalence rates with 95% uncertainty intervals between 1990-2019. The temporal trends of the DALYs and prevalence rates of EDs were assessed according to the estimated annual percentage changes.
RESULTS
In our study, we found that the burden of EDs continuously increased globally from 1990 to 2019. Although females accounted for more EDs cases, the burden of EDs in males had a greater increment. Meanwhile, the burden of EDs was associated with the high sociodemographic index (SDI) over the past 30 years and the human development indexes in 2019.
CONCLUSION
EDs, predominantly in high-income countries, are rising globally, especially in Asia, highlighting the need for resource planning and medical policy prioritization across all SDI quintiles.
Core Tip: This study offered a comprehensive assessment of the global burden of eating disorders (EDs) among children and adolescents over three decades using data from the Global Burden of Disease Study 2019. We observed a continuous increase in the disability-adjusted life years and prevalence rates of anorexia nervosa and bulimia nervosa worldwide. Notably, while EDs predominantly affected females, the relative increase in burden was more significant among males. The study highlighted an association between higher sociodemographic index regions and increased EDs burden, underscoring the need for targeted healthcare strategies across varying socioeconomic landscapes.
