中文摘要：

目的对因听力相关疾病就诊的成人患者年龄因素进行分析,了解听力损失年龄分布特征,为听力损失的预防及干预策略的制定提供依据。方法对首都医科大学附属北京同仁医院临床听力学中心2009年6月1日至2009年8月31日因听力相关疾病就诊的3 018例成人患者的年龄分布进行分析,并比较不同听力损失程度、听力损失类型、听力曲线类型的年龄分布特征。结果①患者年龄分布集中于41~60岁,占全体就诊患者的44.70%;②除正常听力外,轻度、中度、重度和极重度听力损失分布比例最高的年龄范围均为51~60岁;③传导性听力损失主要分布在低年龄范围,感音神经性和混合性听力损失分布比例最高的年龄范围均为51~60岁;④陡降型听力损失分布比例最高的年龄范围为51~60岁,平坦型和＂U＂型听力损失在60岁以下呈均衡分布。结论成人听力损失在程度、类型及听力曲线类型上均呈现出明显的年龄分布特征,感音神经性及混合性听力损失及听阈曲线为陡降型者以51~60岁年龄段为多见。

英文摘要：

Objective Age distribution of hearing loss was analyzed for public policy efforts of hearing loss prevention and rehabilitation.Methods According to the archived records of the Clinical Audiology Center of Beijing Tongren Hospital,Capital Medical University,3 018 audiometric records of adult cases were available during June 1,2009,to August 31,2009.Age distribution was analyzed by different degree,type of hearing loss and audiometric configuration.Results ①Age distribution focused on 41~60 year old,which contributed 44.70% of hearing loss.②Age distribution by hearing loss degree： mild,moderate,severe and profound hearing loss focused on 51~60 year old.③Age distribution by hearing loss type： conductive hearing loss focused on lower age,sensorineural and mixed hearing loss most focused on 51~60 year old.④ Age distribution by audiometric configuration： Slopping hearing loss focused on 51~60 year old,however,the flat and U-shaped hearing loss showed nearly flat distribution under 60 year old.Conclusion Hearing loss showed obvious characteristic of age distribution on the degree,type of hearing loss and audiometric configuration.
