The aim of this study was to investigate occupational noise exposure and hearing defects among sawmill workers in the south of Thailand. Seven hundred sawmill workers participated, of which 335 (47.9%) were male. The mean age of the sawmill workers was 33.5 years ( 10.2), and more than 60% were <35 years old; 75.1% of the workers had less than 5 years of work experience. Only about one in four workers (25%) had been trained in use of personal protective equipment (PPE), and half of the participants never or rarely wore PPE while working. The prevalence rate of noise-induced hearing loss (NIHL) was 22.8% ( = 42). Male workers had significantly higher risk than female workers (odds ratio [] = 2.21). Workers aged older than 25 years had significantly higher risks for NIHL ( = 3.51-12.42) than workers younger than 25 years. Sawing workers had higher risk for NIHL than office workers ( = 3.07).
本研究旨在调查泰国南部锯木厂工人的职业噪声暴露和听力缺陷。700 名锯木厂工人参与了研究，其中 335 名（47.9%）为男性。锯木厂工人的平均年龄为 33.5 岁（10.2），超过 60%的工人年龄小于 35 岁；75.1%的工人工作经验不足 5 年。只有大约四分之一的工人（25%）接受过个人防护设备（PPE）使用方面的培训，而一半的参与者在工作时从不或很少佩戴 PPE。噪声性听力损失（NIHL）的患病率为 22.8%（=42）。男性工人的患病风险显著高于女性工人（优势比[]=2.21）。年龄大于 25 岁的工人比年龄小于 25 岁的工人患 NIHL 的风险显著更高（=3.51-12.42）。锯木工人患 NIHL 的风险高于办公室工人（=3.07）。
