To assess the disease burden and trends of age-related and other hearing loss in China from 1990 to 2021, and to project future developments through 2030, thereby informing the optimisation of healthcare resource allocation and the formulation of targeted prevention and control strategies.
Data sourced from the 2021 Global Burden of Disease (GBD) study. Indicators including the number of prevalence cases, Years Lived with Disability (YLDs), and age-standardized rates for age-related and other hearing loss in China were extracted. Joinpoint regression models were used to analyse temporal trends, calculating annual percentage change (APC) and average annual percentage change (AAPC) with 95% confidence intervals. Bayesian age-period-cohort (BAPC) models projected disease burden for 2022-2030.
Between 1990 and 2021, the number of prevalence cases and YLDs for age-related and other hearing loss in China increased by 125.06% (AAPC=2.65%, P<0.001) and 135.13% (AAPC=2.79%, P<0.001), respectively. Crude rates of prevalence and YLDs increased by 86.10% and 94.43%, respectively, whereas age-standardized rates of prevalence YLDs showed smaller increases with AAPCs of 0.19% and 0.28%. Absolute disease burden values were higher among males than females, though females exhibited faster growth rates. The most pronounced increase in disease burden occurred among the working-age population aged 20-54 years. Moderate and profound hearing loss showed significant growth, whereas the prevalence of complete hearing loss declined. Projections indicate that age-standardized rates of prevalence YLDs will continue to rise through 2030, albeit at a slower pace.
The disease burden of age-related hearing loss in China continues to rise, with population ageing as the primary driver. Sex, age, and severity differences exist within this burden, necessitating the development of lifecycle-spanning and differentiated hearing health prevention and control strategies. These should prioritize working-age populations and female cohorts, while strengthening early intervention and noise control measures.
