Global, regional, and national burdens of eating disorders from 1990 to 2021 and projection to 2035

This is the first study to use the GBD 2021 data to provide a comprehensive in-depth study of the global, regional, and national burdens of eating disorders between 1990 and 2021. In this study, we explored the deeper drivers of the disease burden using frontier, decomposition, and health inequality analyses, in addition to describing the burden of mortality, morbidity, and DALYs in eating disorders. Potential trends through 2035 were also projected using BAPC modeling. We found that the disease burden imposed by eating disorders was gradually increasing. Health inequalities due to the wealth gap had become more severe. This study offered the most current and comprehensive global assessment of the burden of eating disorders, providing critical and updated evidence for healthcare professionals, public health practitioners, and policymakers worldwide. Emphasizing the holistic treatment of mental and physical health, and fostering global collaboration and data sharing were critical for advancing the study and prevention of eating disorders.
