Data on the prevalence of disabling hearing loss (DHL) in Brazil is scarce, which impacts healthcare professionals' knowledge on the extent of the problem.
This study aimed at estimating DHL prevalence in the municipality of Juiz de Fora, Minas Gerais, to identify individual-related variables and find risk areas.
This was a descriptive sectional population study held from January to October of 2009. We randomly selected 349 households with 1,050 individuals who with ages ranging between 4 days and 95 years. The data collection instruments were: WHO structured questionnaire, ENT examination and laboratory tests. Chi-square and Poison regression models were used for analyses.
DHL prevalence was estimated at 5.2% (95% CI = 3.1 to 7.3) which was classified as moderate in 3.9% (95% CI = 0.001 to 0.134), severe in 0.9% (95% CI = 0.001 to 0.107) and profound in 0.4% (95% CI = 0.001 to 0.095). We found correlation between DHL and tinnitus; age over 60 years and low educational level.
Our data obtained pointed to the need to create hearing health programs targeted to specific risk groups, promoting quality of life for hearing impaired patients.
巴西失能性听力损失（DHL）的流行数据稀缺，这影响了医疗保健专业人员对问题严重程度的了解。
本研究旨在估计米纳斯吉拉斯州茹伊斯-迪福拉市的 DHL 患病率，以确定与个体相关的变量并发现风险区域。
这是一项于 2009 年 1 月至 10 月进行的描述性、截面人群研究。我们随机选择了 349 个家庭，共 1050 人，年龄在 4 天至 95 岁之间。数据收集工具包括：世界卫生组织结构化问卷、耳鼻喉科检查和实验室测试。采用卡方检验和泊松回归模型进行分析。
DHL 的患病率估计为 5.2%（95%CI=3.1 至 7.3），其中中度为 3.9%（95%CI=0.001 至 0.134），重度为 0.9%（95%CI=0.001 至 0.107），深度为 0.4%（95%CI=0.001 至 0.095）。我们发现 DHL 与耳鸣之间存在相关性；年龄超过 60 岁和教育程度低。
我们获得的数据表明，需要为特定的高危人群制定听力健康计划，以提高听力受损患者的生活质量。
