背景以往的研究表明，自述的听力障碍可能会增加农业伤害的风险。然而，自我报告的听力测量可能会不准确和主观感知。我们通过测量听力来评估农业伤害与听力损失和其他听力特征的关系。方法研究对象为参加爱荷华州认证安全农场研究的150名农民。在1999年9月至2002年10月期间，每隔2-5个月通过电话访问收集伤害信息。从1998年到2002年，每年使用纯音测听仪测量听力水平。采用多元泊松回归模型计算调整后的损伤率比。结果较好耳听力损失（RR = 1.62）、听力不对称（RR = 1.67）和自述听力一般/较差（RR = 1.96）与农业伤害风险显著相关。值得注意的是，自我报告的听力可能比纯音听力（PTA）更能预测损伤。暴露在噪音中增加了听力损失或听力不对称的农民受伤的风险。偶尔使用听力保护与农业伤害显著相关。结论本研究增加了大量证据，证明听力损失是农业伤害的风险因素。预防听力损失和噪音暴露可能对减轻农业伤害的负担很重要。
Background Previous studies suggested that hearing impairment based on self-report might increase the risk of agricultural injuries. However, self-reported hearing measures may be subject to inaccuracy and subjective perception. We assessed the association of agricultural injuries with hearing loss and other hearing characteristics using measured hearing.Methods Study subjects were 150 farmers who participated in the Iowa Certified Safe Farm study. Injury information was collected by telephone interviews at 2-5 month intervals from September 1999 to October 2002. Hearing levels were measured annually using the pure tone audiometry from 1998 to 2002. Adjusted rate ratios of injuries were calculated using the multivariate Poisson regression model.Results Hearing loss in the better ear (RR = 1.62), hearing asymmetry (RR = 1.67), and fair/poor self-reported hearing (RR = 1.96) were significantly associated with the risk of agricultural injuries. It is notable that self-reported hearing might be a stronger predictor of injuries than pure tone audiometry (PTA). Exposure to noise elevated the risk of injuries in those farmers with hearing loss or hearing asymmetry. The occasional use of hearing protection was significantly associated with agricultural injuries.Conclusions This study adds substantial evidence that hearing loss acts as a risk for agricultural injuries. Prevention of hearing loss and noise exposure may be important in reducing the burden of agricultural injuries.
