Hearing loss is prevalent among adults in the farming community, with some evidence it begins in childhood. Our objective was to compare hearing thresholds of Ohio farm youth to published data on national norms.
Baseline data were collected on youth (n = 212) in 1994-1996 with follow-up (n = 132) in 2003-2004 including pure-tone air conduction thresholds at 0.5, 1, 2, 3, 4, 6, and 8 kHz.
When compared to nationally-representative data, study youth had a higher prevalence of hearing loss. The high-frequency range was most affected, particularly at 6 kHz where nearly 50% of the farm youth exhibited some degree of hearing loss at baseline testing. The prevalence of noise-induced threshold shifts, characterized by an audiometric notch, was nearly twice that of the national sample.
These data suggest that hearing loss, which is common among adult farmers, may be problematic for farm youth as well.
听力损失在农业社区的成年人中很普遍，有证据表明其始于儿童时期。我们的目标是将俄亥俄州农场青年的听力阈值与已公布的全国标准数据进行比较。
在1994 - 1996年收集了青年（n = 212）的基线数据，并在2003 - 2004年进行了随访（n = 132），包括0.5、1、2、3、4、6和8千赫兹的纯音气导阈值。
与全国代表性数据相比，研究中的青年听力损失患病率更高。高频范围受影响最大，尤其是在6千赫兹处，近50%的农场青年在基线测试时表现出某种程度的听力损失。以听力图切迹为特征的噪声诱发阈值变化的患病率几乎是全国样本的两倍。
这些数据表明，听力损失在成年农民中很常见，对农场青年也可能是个问题。
