摘要

Background

Age-related macular degeneration (AMD) is a critical public health issue, requiring prioritized public health strategies.

Methods

Based on the Global Burden of Disease Study 2021, AMD burden and risk factors were analyzed, considering variables such as sex, age, and location. Age-standardized rates (ASR) were employed to evaluate and compare the burdens across different regions. Frontier analysis was used to determine the lowest achievable burden based on the Sociodemographic Index (SDI), while decomposition analysis revealed factors influencing age-related macular degeneration burden change.

Results

Globally, in 2021, ASR of prevalence and disability-adjusted life years (DALYs) were 94.00 (95% UI 78.32, 114.42) per 100,000 and 6.78 (95% UI 4.70, 9.32) per 100,000 respectively. Additionally, a reduction of smoking exposure to its theoretical minimum risk exposure level (TMREL) would lead to an estimated 10.0% decrease in AMD DALYs in 2021. Frontier analysis suggested that Nepal, Iran (Islamic Republic of), and Nigeria were the top three countries with the most substantial potential for reducing disparities. Decomposition analysis indicated that population growth and aging are the primary driving factors for the increase in AMD DALYs.

Conclusions

We identify countries and territories with potential for improvement and emphasize the importance of equitable, cost-effective control strategies, particularly tobacco control.
