Abstract

Traffic enforcers are exposed to various occupational health and safety hazards, including noise pollution, which may lead to occupational hearing loss. This cross-sectional study aimed to estimate the prevalence of hearing loss and to assess the relationship between occupational noise exposure level (ONEL) and abnormalities in air conduction thresholds among Metropolitan Manila Development Authority (MMDA) employees along Epifanio delos Santos Avenue, Philippines. Eight-hour ONELs were measured among 108 participants working with greater than 5 years of service. Participants had hearing evaluations using pure tone audiometry (PTA) to calculate the prevalence of hearing loss. Generalized linear models with a Poisson distribution were fitted to estimate the association between ONEL and audiologic abnormalities, controlling for confounding factors. Approximately 16% of employees had hearing loss. The prevalence of hearing loss was higher with ONEL exposures greater than 85 A-weighted decibels (dBA), with traffic enforcers exposed to higher ONELs than office workers. ONELs greater than 85 dBA were related to audiologic abnormalities at different frequencies in PTA. The prevalence of audiologic abnormalities at 4000 Hz and 6000 Hz was 48% higher (adjusted prevalence ratio [aPR], 1.48; 95% CI, 1.12-1.96) and 25% higher (aPR, 1.25; 95% CI, 1.00-1.55), respectively, among participants with ONELs greater than 85 dBA than with ONELs less than or equal to 85 dBA. Participants exposed to ONELs greater than 85 dBA, more likely traffic enforcers, may have increased risk of audiologic abnormalities. Regular ONEL monitoring is warranted for occupational risk assessment of traffic enforcers. A hearing conservation program may need to be considered for this population. Additional studies are needed to determine trends in hearing deterioration among traffic enforcers.

马尼拉大都会发展局员工的职业噪声暴露水平与纯音测听异常之间的关系:一项横断面研究。
交通执法人员暴露于包括噪声污染在内的各种职业健康和安全危害中,这可能会导致职业性听力损失。这项横断面研究旨在估算听力损失的发生率,并评估菲律宾埃皮法尼奥-德洛斯-桑托斯大道沿线的马尼拉大都会发展局(MMDA)员工的职业噪声暴露水平(ONEL)与空气传导阈值异常之间的关系。对 108 名工龄超过 5 年的参与者进行了 8 小时 ONEL 测量。参与者通过纯音测听(PTA)进行听力评估,以计算听力损失的发生率。采用泊松分布的广义线性模型来估算 ONEL 与听力异常之间的关系,并对混杂因素进行了控制。约 16% 的员工患有听力损失。当 ONEL 暴露值大于 85 A 加权分贝(dBA)时,听力损失的发生率较高,其中交通执法人员的 ONEL 暴露值高于办公室工作人员。ONEL 超过 85 分贝与 PTA 不同频率的听力异常有关。与 ONEL 值小于或等于 85 dBA 的参与者相比,ONEL 值大于 85 dBA 的参与者在 4000 Hz 和 6000 Hz 的听觉异常发生率分别高出 48% (调整后发生率比 [aPR],1.48;95% CI,1.12-1.96)和 25% (aPR,1.25;95% CI,1.00-1.55)。暴露于 ONEL 超过 85 dBA 的参与者(更可能是交通执法人员)可能会增加听力异常的风险。在对交通执法人员进行职业风险评估时,有必要对 ONEL 进行定期监测。对于这类人群,可能需要考虑听力保护计划。还需要进行更多的研究,以确定交通执法人员听力退化的趋势。

期刊介绍: The Journal of Occupational and Environmental Hygiene ( JOEH ) is a joint publication of the American Industrial Hygiene Association (AIHA®) and ACGIH®. The JOEH is a peer-reviewed journal devoted to enhancing the knowledge and practice of occupational and environmental hygiene and safety by widely disseminating research articles and applied studies of the highest quality. The JOEH provides a written medium for the communication of ideas, methods, processes, and research in core and emerging areas of occupational and environmental hygiene. Core domains include, but are not limited to: exposure assessment, control strategies, ergonomics, and risk analysis. Emerging domains include, but are not limited to: sensor technology, emergency preparedness and response, changing workforce, and management and analysis of "big" data.
