Noise and pesticide exposure is frequent among Brazilian agricultural workers, however, few studies analyzed its association with work accidents.
To investigate the association between self-reported noise and pesticide exposure and self-reported work accidents among rural workers.
Cross-sectional study performed in Conceição das Pedras, southern Minas Gerais, Brazil. We administered a questionnaire to 170 rural workers from April through October 2014. We subjected the data to unconditional multiple logistic regression analysis by means of the stepwise method.
The prevalence of work accidents was 11.8% (95%CI 7.3-17.6). Independent variables associated with occurrence of work accidents were: use of the fungicide Priori (OR 11.8; p=0.007), use of hand-held power tools (OR 8.28; p=0.010), noise-induced hearing loss (OR 38.60; p=0.022) and length in the job (OR 1.04; p=0.034).
We did not find association between work accidents and self-reported combined noise and pesticide exposure. The results, however, evidenced factors significantly related to the occurrence of work accidents, which identification might serve to ground preventive actions. We recommend performing additional studies likely to overcome detected limitations to establish the role of combined exposures in work accidents.
巴西农业工人经常暴露于噪音和农药环境中，然而，很少有研究分析其与工伤事故的关联。
调查农村工人自我报告的噪音和农药暴露与自我报告的工伤事故之间的关联。
在巴西米纳斯吉拉斯州南部的康塞桑迪佩德拉斯进行横断面研究。2014年4月至10月，我们对170名农村工人进行了问卷调查。我们采用逐步法对数据进行无条件多元逻辑回归分析。
工伤事故的发生率为11.8%（95%可信区间7.3 - 17.6）。与工伤事故发生相关的独立变量为：使用杀菌剂Priori（比值比11.8；p = 0.007）、使用手持式电动工具（比值比8.28；p = 0.010）、噪声性听力损失（比值比38.60；p = 0.022）和工作年限（比值比1.04；p = 0.034）。
我们未发现工伤事故与自我报告的噪音和农药联合暴露之间存在关联。然而，研究结果表明了与工伤事故发生显著相关的因素，识别这些因素可能有助于采取预防措施。我们建议开展更多研究，以克服已发现的局限性，从而确定联合暴露在工伤事故中的作用。
