Analysis reveals increasing occupational noise-induced hearing loss burden in Asia, indicating growing inequality.
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.
