To identify the prevalence of hearing loss for the population in the urban area.
A cross-sectional household survey based on the World Health Organization Ear and Hearing Disorders Survey Protocol was conducted in 298 households in the urban area of Monte Negro, Rondonia, Northern Brazil, from 2005 to 2007. Ear examinations, behavioral audiometry and pure tone audiometry were conducted on 577 individuals.
The results showed that 3.8% (95%CI 2.17;5.45) of population were classified in the disabling hearing impairment category. The prevalence of moderate hearing impairment was 3.4%; severe impairment was 0.4%; and profound hearing impairment was not found.
The impairing hearing loss prevalence found in this study is within of the international prevalence for this level of hearing loss and smaller than observed in a previous study in the South region of Brazil.
确定城市地区人群的听力损失患病率。
2005 年至 2007 年，在巴西北罗赖马州蒙特内格罗的城区的 298 户家庭中进行了一项基于世界卫生组织耳与听力障碍调查方案的横断面家庭调查。对 577 人进行了耳部检查、行为测听和纯音测听。
结果显示，3.8%（95%CI 2.17;5.45）的人群被归类为失能性听力损伤类别。中度听力损伤的患病率为 3.4%；重度损伤为 0.4%；未发现极重度损伤。
本研究发现的听力损失患病率处于国际同级别听力损失的患病率范围内，且小于巴西南部之前研究的观察结果。
