Background: Age-related hearing loss is a common degenerative disorder among older individuals that warrants attention in a society with an aging population. The objectives of this study were to investigate age-related hearing loss and to estimate the prevalence of age-related hearing loss in Korea using a healthcare center-based study.
Methods: Persons older than 50 years of age visiting a selected health promotion center were recruited (n=10,118). Pure tone audiometry was performed on the subjects, and the average hearing thresholds were obtained using 500 Hz, 1,000 Hz, 2,000 Hz, and 4,000 Hz for the six-dimension method.
Results: The prevalences of age-related hearing loss for subjects older than 65 years were 36.8% at a cutoff of ≥26 dBHL and 10.1% at a cutoff of ≥41 dBHL. When age and gender were corrected for, the estimated prevalences of age related hearing loss for those subjects greater than 65 years in the general population were 45.8% at a cutoff value of ≥26 dBHL and 14.8% at a cutoff value of ≥41 dBHL.
Conclusion: Our study provides important information concerning age-related hearing loss in Korea. The estimated prevalence of age-related hearing loss in the general population in Korea was high.
