To estimate prevalence of severe-profound hearing loss (HL) in South Korea, and analyse a 10-year trend of HL according to age, sex, and region by using a nationwide population-based database. Retrospective review from Korean National Health Insurance Service from 2006 to 2015. The degree of severe-profound HL was classified into six grades, based mostly on HL worse than 60 dB HL for both ears. Absolute number of HL was the highest in 2011 (0.25 million; males, 0.14 million; females, 0.11 million); it decreased gradually until 2015. Total HL prevalence was the highest in 2010 (0.5%; 251,954), and decreased annually to 2015 (0.46%; 237,272). The trend of HL prevalence showed a gradual decrease from 2010 to 2015. Prevalence of severe-profound HL was always higher in the male population (1.19 times higher than female in 2015). Prevalence of HL was higher in rural areas than in urban areas (1.4 times higher in 2015). Number of severe-profound HL in South Korea decreased gradually in all age groups annually, even though some older age groups had the highest peak in 2010-2011. Prevalence of severe-profound HL decreases gradually in all age groups annually in South Korea, although the absolute number of HL cases increases rapidly among those aged over 80 years.
为了评估韩国重度-极重度听力损失（HL）的流行率，并利用全国人口为基础的数据库，按年龄、性别和地区分析 HL 10 年趋势。对韩国国民健康保险服务局 2006 年至 2015 年的数据进行回顾性分析。根据双耳 HL 均大于 60dB HL 的情况，将重度-极重度 HL 分为六个等级。HL 的绝对数量在 2011 年最高（0.25 百万；男性 0.14 百万；女性 0.11 百万）；此后逐渐减少，直到 2015 年。总 HL 流行率在 2010 年最高（0.5%；251954 人），并逐年下降至 2015 年（0.46%；237272 人）。HL 流行趋势从 2010 年到 2015 年逐渐下降。重度-极重度 HL 的流行率在男性中始终高于女性（2015 年男性是女性的 1.19 倍）。农村地区 HL 的流行率高于城市地区（2015 年农村地区是城市地区的 1.4 倍）。尽管一些年龄较大的组在 2010-2011 年达到了最高峰值，但韩国所有年龄组每年的重度-极重度 HL 数量都在逐渐减少。尽管 80 岁以上人群的 HL 病例绝对数量迅速增加，但韩国所有年龄组每年的重度-极重度 HL 流行率都在逐渐下降。
