2021年世界听力报告

2021年世界听力报告根据世卫组织有史以来第一份《世界听力报告》估计，到2050年，将有近25亿人患有某种程度的听力损失。报告指出，每年因未确诊的听力损失而造成的损失为近1万亿美元。与此同时，在耳部和听力保健方面的投资具有成本效益。2050年将会有25亿人患有听力损失世界卫生组织在报告中预估到，至2050年，将有近25亿人患有某种程度的听力损失，其中至少有7亿人需要康复服务。这就意味着，到2050年，预计将会有1/4的人患有听力障碍。现今，有15亿人患有一定程度的听力损失。全球和世界卫生组织区域内，患有一定程度听力损失的人口数量为：全球范围内现今：15亿人至2050年：25亿人非洲现今：1.36亿人至2050年：3.37亿人美国现今：2.17亿人至2050年：3.32亿人东地中海地区现今：7800万人至2050年：1.94亿人欧洲地区现今：1.96亿人至2050年：2.36亿人东南亚地区现今：4.01亿人至2050年：6.66亿人西太平洋地区现今：5.46亿至2050年：7.76亿世界卫生组织写道，如不采取应对，听力损失将对人们的健康和福祉产生影响，同时也会因人们在交流，教育和就业中受到排挤而造成巨大的经济损失。该报告指出，很多种听力损失情况可以通过行之有效的方法进行预防。有超过10亿的年轻人可以避免患上听力损失，而约有2亿人患有可预防或者可治疗的慢性耳部感染。这两种情况都需要采取紧急应对措施。有更多人需要治疗世界卫生组织在报告中写道，创新的、具有成本效益的技术和临床解决方案可以改善大多数听力损失患者的生活质量，且目前已经有数百万人从中受益。将技术力量与公共卫生规划相结合，可以确保所有人受益其中，尤其是那些身处服务水平较低以及偏远地区的人们。年损失1万亿美元报告指出，按照目前的流行率，每年因未确诊的听力损失而造成的损失为近1万亿美元。如不采取行动，这一数字在未来几十年将继续上升。世界卫生组织建议，在国家卫生计划中应涵盖全民听力和耳部保健服务，以减少未确诊的听力损失患者数量。这不仅可以帮助到听力损失患者，同时还可以减少因听力损失得不到治疗而引起的社会成本。按照世界卫生组织的数据所示，在耳部和听力保健方面的投资已被证实具有成本效益。预计政府每投入1美元，便可获得近16美元的回报。COVID-19世界卫生组织在报告中还指出，COVID-19在世界范围内造成的封锁凸显了听力的重要性，以及对耳部和听力保健的需求。当无法实现视觉和社交接触时，听觉还可以发挥作用。eWorldHealthOrganizationWORLDREPORT
