To investigate the association between self-reported hearing difficulties and occupational exposure to industrial dust in workers in southern Brazil.
This is a cross-sectional analytical study conducted with data from the National Health Survey (Pesquisa Nacional de Saúde, 2013). The dependent variable was self-reported hearing impairment, and the primary independent variable was occupational exposure to industrial dust. The covariables were: sex, skin color, age in complete years, exposure to noise, and exposure to chemical substances. The variables of occupational exposure to noise and chemical substances were used as adjustment variables (confounding variables), and the analyses were stratified per state (Santa Catarina, Paraná, and Rio Grande do Sul) to verify the difference in magnitude results per region. For the crude and adjusted analysis, the odds ratio (OR) was used as a measure of association, estimated through the logistic regression analysis. The data were analyzed through the software Stata, version 14.
Regarding the main exposure, 10.1% of the sample (n = 490) reported being exposed to industrial dust in an occupational environment, while 7.0% reported hearing impairment. In the final analysis, workers exposed to industrial dust were 1.77 times more likely to report hearing impairment when compared to individuals not exposed to this agent.
There was an association between hearing impairment and exposure to industrial dust in workers in the southern region of Brazil.
调查巴西南部工人自我报告的听力困难与职业性接触工业粉尘之间的关联。
这是一项横断面分析研究，使用了来自全国健康调查（2013年全国健康调查）的数据。因变量是自我报告的听力障碍，主要自变量是职业性接触工业粉尘。协变量包括：性别、肤色、周岁年龄、接触噪声和接触化学物质。将职业性接触噪声和化学物质的变量用作调整变量（混杂变量），并按州（圣卡塔琳娜州、巴拉那州和南里奥格兰德州）进行分层分析，以验证各地区结果大小的差异。对于粗分析和调整分析，使用比值比（OR）作为关联度量，通过逻辑回归分析进行估计。数据通过Stata 14版软件进行分析。
关于主要暴露情况，样本中有10.1%（n = 490）报告在职业环境中接触过工业粉尘，而7.0%报告有听力障碍。在最终分析中，与未接触该物质的个体相比，接触工业粉尘的工人报告听力障碍的可能性高出1.77倍。
巴西南部工人的听力障碍与接触工业粉尘之间存在关联。
