This study was designed to assess occupational noise exposure levels, prevalence of temporary hearing loss and associated factors among textile industry workers in Amhara region, Ethiopia.
An institution-based, cross-sectional study was conducted between June and July 2022. Participants were selected via a simple random sampling technique.
Textile industry workers in Bahir Dar and Kombolcha.
A total of 413 study participants were included in the data analysis.
The data were collected using a structured questionnaire. Area noise exposure levels in different work sections were measured using a sound level meter. Data analysis was done using Stata Version 14.0 software. Bivariate and multivariable logistic regression analysis were used to identify factors associated with temporary hearing loss. Adjusted OR with 95% CI and p-value<0.05 were used to determine statistical significance.
A total of 413 workers participated in the study with a response rate of 97.9%. The age of respondents ranged from 22 to 59 years (median age 32 years). The prevalence of work-related temporary hearing loss was 38.7% (95% CI 34.14% to 43.6%). Weaving department (AOR=6.6, 95% CI 3.06 to 14.3) and higher sound pressure level (>90 dBA) (AOR=7.9; 95% CI 2.6 to 23.7) were significantly associated with work-related temporary hearing loss among textile workers.
The prevalence of work-related temporary hearing loss among textile industry workers was high. Weaving department and higher sound pressure level were significantly associated with work-related temporary hearing loss. Implementation of noise reduction measures, particularly in the weaving department, should be prioritised. Provision and enforcement of the use of hearing protection devices and establishment of regular hearing screening programmes to monitor workers' auditory health are advisable.
本研究旨在评估埃塞俄比亚阿姆哈拉地区纺织业工人的职业噪声暴露水平、暂时性听力损失患病率及相关因素。
2022年6月至7月进行了一项基于机构的横断面研究。通过简单随机抽样技术选取参与者。
巴赫达尔和孔博尔查的纺织业工人。
共有413名研究参与者纳入数据分析。
使用结构化问卷收集数据。使用声级计测量不同工作区域的噪声暴露水平。使用Stata 14.0软件进行数据分析。采用双变量和多变量逻辑回归分析来确定与暂时性听力损失相关的因素。使用调整后的比值比（OR）及95%置信区间（CI）和p值<0.05来确定统计学意义。
共有413名工人参与研究，应答率为97.9%。受访者年龄在22至59岁之间（中位年龄32岁）。与工作相关的暂时性听力损失患病率为38.7%（95%CI 34.14%至43.6%）。织造部门（调整后的比值比[AOR]=6.6，95%CI 3.06至14.3）和较高的声压级（>90分贝）（AOR=7.9；95%CI 2.6至23.7）与纺织工人中与工作相关的暂时性听力损失显著相关。
纺织业工人中与工作相关的暂时性听力损失患病率较高。织造部门和较高的声压级与工作相关的暂时性听力损失显著相关。应优先实施降噪措施，特别是在织造部门。建议提供并强制使用听力保护装置，并建立定期听力筛查计划以监测工人的听觉健康。
