The number of people with impaired hearing is increasing; knowing its magnitude is essential for public health.
To study the prevalence and determinants of impaired hearing in Itajaí/SC.
A population-based survey based on a World Health Organization protocol. Field research was carried out from July 2008 to 2011. Procedures for evaluating hearing in households: questionnaire, measurement of noise, otoscopy, pure tone audiometry at 1000, 2000, and 4000 Hz, tympanometry, and acoustic reflexes: individuals above 4 years; children under 4 years: evoked otoacoustic emissions (OAE), cocleo-palpebral reflex(CPR), tympanometry, and acoustic reflexes. In the elderly population a questionnaire of perception of hearing loss was applied.
The study sample consisted of 379 individuals--45.38% were males and 54.62% were females. Age-range: 11.34% up to 10 years; 64.39% 10 to 60 years, 24.27% over 60 years. Evaluation of the best hearing ear showed that 74.1% of residents had normal hearing, 18.9% had mild hearing loss, 5.1% had moderate hearing loss, 1.9% had severe hearing loss. Disabling impaired hearing was detected in 26 subjects: one child (otitis media); four adults (one otitis, one noise-induced, two idiopathic); 21 elderlies (presbyacusis). Of eight children under 4 years all presented CPR, three were normal examinations, two had absent OAE bilaterally, one had absent OAE in the right ear and one in the left ear.
The prevalence of disabling impaired hearing in Itajaí was 7%; the highest prevalence was in the 50-year and above age group--the main cause was presbyacusis.
听力受损的人数正在增加；了解其严重程度对公共卫生至关重要。
研究伊塔雅伊/圣卡塔琳娜州听力受损的患病率和决定因素。
基于世界卫生组织方案的基于人群的调查。实地研究于 2008 年 7 月至 2011 年进行。家庭听力评估程序：问卷、噪声测量、耳镜检查、1000、2000 和 4000 Hz 纯音测听、鼓室图和听觉反射：4 岁以上个体；4 岁以下儿童：听觉诱发电位（OAE）、耳蜗-鼓膜反射（CPR）、鼓室图和听觉反射。老年人群中应用了听力损失感知问卷。
研究样本由 379 人组成——45.38%为男性，54.62%为女性。年龄范围：11.34%至 10 岁；64.39%为 10 至 60 岁，24.27%为 60 岁以上。最佳听力耳评估显示，74.1%的居民听力正常，18.9%有轻度听力损失，5.1%有中度听力损失，1.9%有重度听力损失。26 名居民存在残疾性听力障碍：1 名儿童（中耳炎）；4 名成人（1 名中耳炎，1 名噪声性，2 名特发性）；21 名老年人（老年性聋）。8 名 4 岁以下儿童均行 CPR 检查，3 名检查正常，2 名双侧 OAE 缺失，1 名右耳 OAE 缺失，1 名左耳 OAE 缺失。
伊塔雅伊听力障碍的患病率为 7%；患病率最高的是 50 岁及以上年龄组——主要原因是老年性聋。
