Global trends and health inequalities in mental disorders among older adults: a comprehensive analysis using global burden of disease 2021 data.

ABSTRACT:

Objective

This study aims to analyze global trends and health inequalities in mental disorders among older adults (≥60 years) using Global Burden of Disease (GBD) 2021 data, with a focus on informing equity-focused public health strategies to address disparities in burden and access to care.

Methods

Using GBD 2021 data, we examined mental disorders in adults ≥60 across 204 countries (1990-2021). We calculated age-standardized incidence (ASIR) and disability-adjusted life years (DALYs) rates and estimated annual percentage change (EAPC). Bayesian Age-Period-Cohort modeling and frontier analysis assessed trends and projections. Analyses used R (v4.4.2) and JD_GBDR software.

Findings

In 2021, there were 74.9 million (95%UI: 59.8-94.2) new mental disorder cases among olde
