This study addressed the relationship of hearing loss and coexposure to solvents and noise among farmers and ranchers in central United States.
The surveillance study included surveys to stratified random samples of operations in 2018 and 2020 (n = 34,146), requesting information on injuries, illnesses, exposures, and preventive measures. Responses (n = 7495) were analyzed using hierarchical multinomial logistic regression, adjusting for personal and work characteristics.
Nearly 60% of respondents exposed to both solvents and noise reported hearing loss. The exposures increased the adjusted odds of moderate/severe hearing loss as follows: solvents alone, (odds ratio [OR], 1.49; 95% confidence interval [CI], 0.93-2.38), noise alone (OR, 4.42; 95% CI, 3.39-5.76), and coexposure to both noise and solvents (OR, 6.03; 95% CI, 4.67-7.78).
Solvent exposure, along with noise, should be considered in hearing conservation programs among farmers and ranchers.
本研究探讨了美国中部农民和牧场主的听力损失与同时接触溶剂和噪声之间的关系。
这项监测研究包括在2018年和2020年对分层随机抽样的作业进行调查（n = 34,146），询问有关伤害、疾病、接触情况和预防措施的信息。使用分层多项逻辑回归分析了答复（n = 7495），并对个人和工作特征进行了调整。
近60%同时接触溶剂和噪声的受访者报告有听力损失。这些接触因素增加中度/重度听力损失的调整后比值如下：仅接触溶剂（比值比[OR]，1.49；95%置信区间[CI]，0.93 - 2.38），仅接触噪声（OR，4.42；95% CI，3.39 - 5.76），以及同时接触噪声和溶剂（OR，6.03；95% CI，4.67 - 7.78）。
在农民和牧场主的听力保护计划中，应考虑溶剂接触以及噪声接触。
