Objective:
We characterized long-term trends, regional disparities, and socioeconomic inequalities of occupational noise-induced hearing loss (ONIHL) among Asian working populations.
Methods:
Using GBD 2023 data, we analyzed DALYs and age-standardized DALY rates (ASDR) from 1990-2023. Joinpoint regression, spatial autocorrelation, socioeconomic associations (SDI/HDI), inequality metrics, and projections (2024-2053) were employed.
Results:
From 1990-2023, Asian ONIHL DALYs increased while ASDR remained stable. South/Southeast Asia, males, and older workers bore the highest burden. ASDR was inversely associated with SDI and HDI, with widening cross-country inequalities. Projections suggest rising absolute burdens and regional disparities through 2053.
Conclusion:
The ONIHL burden in Asia persists and is increasingly unequal, disproportionately affecting low-development regions. Targeted prevention and strengthened occupational health management are essential to mitigate future impacts.

The human ear can perceive an extensive range of sound intensity, necessitating the use of the logarithmic scale to define a physical quantity—the intensity level. It is a ratio of two intensities and hence a...
