A cross-sectional survey was conducted among 3646 persons, 15 to 23 years of age, in the southern plains District of Sarlahi, Nepal, to assess the prevalence and severity of hearing loss and middle-ear dysfunction, and adverse effects of hearing loss on social integration. Between 2006 and 2008, subjects were enumerated and underwent otoscopic, tympanometric, and audiometric evaluations at central sites in villages. Hearing loss was diagnosed in subjects who failed a hearing screening and exhibited an average air conduction threshold value greater than or equal to 30 dBHL in the worse ear. Clinically, 32.8% of subjects exhibited a dull or retracted tympanic membrane, and 18% had abnormal tympanometry. Nearly 12% failed the hearing screening test, among whom more than half, or 6.1% overall, had hearing loss. Hearing-impaired subjects were six- to eight-fold (ORs, with 95% CIs excluding 1.0) more likely to report problems in hearing usual sounds or communicating with other people. Among young adults living in southern Nepal, hearing loss is common, and associated with social disability.
一项横断面调查在尼泊尔南部平原萨勒希地区的 3646 名 15 至 23 岁的人群中进行，以评估听力损失和中耳功能障碍的患病率和严重程度，以及听力损失对社会融合的不良影响。2006 年至 2008 年期间，在村庄的中心地点对受试者进行了计数，并进行了耳镜、鼓室图和声导抗评估。在未通过听力筛查且在较差耳中平均气导阈值大于或等于 30 dBHL 的受试者中诊断为听力损失。临床上，32.8%的受试者表现为鼓膜混浊或回缩，18%的受试者鼓室图异常。近 12%的人未能通过听力筛查测试，其中超过一半，即总体的 6.1%，有听力损失。听力受损的受试者报告听力正常声音或与他人交流有问题的可能性是其他人的六到八倍（OR，95%CI 不包括 1.0）。在尼泊尔南部生活的年轻成年人中，听力损失很常见，并且与社会残疾有关。
