Among agricultural populations, hearing loss caused by excessive noise exposure is common. However, examinations of associations between exposure to agricultural tasks and hearing loss are limited.
Audiometry and lifetime exposure to 11 agricultural tasks were analyzed among 1,568 participants. Gender stratified multivariable linear regression was used to estimate associations between exposure duration and three hearing loss metrics.
Among men, significant associations were observed between hearing loss and hunting or target shooting, all-terrain vehicle (ATV) or motorcycle riding, chain saw use, electric or pneumatic tool use, living on a farm, and all agricultural tasks combined. When all significant exposure metrics were included in a single model, associations remained for hunting or target shooting, electric or pneumatic tool use and living on a farm. Significant associations were sparse among women, and in all cases paradoxical.
Despite imprecise estimation of noise exposure, specific agricultural tasks were associated with hearing loss.
在农业人群中，因过度噪声暴露而导致的听力损失较为常见。然而，有关接触农业作业与听力损失之间关联的研究有限。
对 1568 名参与者进行了听力测试和对 11 项农业作业的终生暴露情况分析。采用性别分层多变量线性回归来评估接触时间与三种听力损失指标之间的关系。
在男性中，与听力损失相关的作业有狩猎或射击、全地形车（ATV）或摩托车驾驶、链锯使用、电动或气动工具使用、务农以及所有农业作业。当将所有显著的暴露指标纳入一个单一模型中时，与狩猎或射击、电动或气动工具使用和务农仍存在关联。在女性中关联较为稀疏，且所有情况均呈矛盾关系。
尽管对噪声暴露的估计不够精确，但特定的农业作业与听力损失相关。
