Global burden and trends of major mental disorders in individuals under 24 years of age from 1990 to 2021, with projections to 2050
Background: Mental disorders are the leading cause of global non-fatal disease burden, with rising prevalence among children, adolescents, and youth. This study analyzed location-, age-, and sex-specific estimates for nine mental disorders from 1990 to 2021 using GBD 2021 data, projecting burden to 2050. Methods: Methods included calculating average annual percentage change (AAPC) and annual percentage change (APC) for age-standardized prevalence…
