木尘是一种可吸入颗粒物，可穿透肺部组织，影响呼吸系统健康。木工厂工人由于暴露在工作环境中，患呼吸道健康问题的风险更大，但现有数据很少。本研究旨在探讨中型木工厂工人慢性呼吸道症状之盛行率、相关因素及个人总木尘浓度。对506名木工厂工人进行了一项基于机构的横断面研究。我们使用简单的随机抽样技术选择研究参与者。我们使用英国医学研究理事会呼吸系统症状问卷进行了一些修改，以评估慢性呼吸系统症状。多因素Logistic回归模型被用来确定的因素。40粉尘测量收集从20个随机选择的工人使用封闭面盒式（CFC）个人采样器。我们使用标准微量天平对灰尘样品进行了重量分析。我们在研究中随机招募了506名工人，应答率为98%。木工慢性呼吸道健康症状的患病率为69.8%，其中咳嗽（54.6%）、痰（52.2%）、喘息（44.6%）、呼吸困难（42.1%）和胸痛（42.9%）的患病率最高。既往职业性粉尘接触史（AOR = 2.09，95%CI; 1.09 - 4.01），工作经验> 5年（AOR = 9.18，95%CI; 5.27 - 16.00），使用生物燃料作为烹饪能源（AOR = 2.42，95%CI; 1.44-4.07）、未接受过职业安全卫生培训（AOR = 3.38，95%CI; 1.20-9.49）是木工慢性呼吸道症状的危险因素。木工粉尘接触水平的几何平均值为10.27 mg/m3，超过了ACGIH规定的限值10 mg/m3。据报告，木工厂工人慢性呼吸道症状的发病率很高。增加的工作经验，使用生物燃料作为烹饪的能源，过去的职业粉尘接触史，没有职业安全和健康培训被确定为风险因素。测得的平均个人木尘接触水平高于推荐的职业阈值限值。因此，应实施减少和控制工人木尘暴露的方法和呼吸道健康意识方案。
Wood dust in a form of inhalable particulates can penetrate the lung tissues and affect respiratory health. Woodwork factory workers are at a greater risk of developing respiratory health problems because of exposure in their working environment, but existing data were few. The aim of this study was to assess the prevalence of chronic respiratory symptoms, associated factors, and concentration of personal total wood dust level among medium-scale woodwork factory workers. An institutional based cross-sectional study was conducted among 506 woodwork factory workers. We selected study participants using a simple random sampling technique. We assessed chronic respiratory symptoms using the British Medical Research Council respiratory symptoms questionnaire with a few modifications. A multivariate logistic regression model was used to identify the factors. Forty dust measurements were collected from 20 randomly selected workers using a closed-face cassette (CFC) personal sampler. We analyzed the dust samples gravimetrically using a standard microbalance scale. We recruited a random sample of 506 workers in the study with a response rate of 98%. The prevalence of chronic respiratory health symptoms among woodworkers was 69.8% with a prevalence of cough (54.6%), phlegm (52.2%), wheezing (44.6%), breathlessness (42.1%), and chest pain (42.9%). Past occupational dust exposure history (AOR = 2.09, 95% CI; 1.09–4.01), work experience > 5 years (AOR = 9.18, 95% CI; 5.27–16.00), using bio-fuel as energy for cooking (AOR = 2.42, 95% CI; 1.44–4.07), and having no occupational safety and health training (AOR = 3.38, 95% CI; 1.20–9.49) were factors that significantly associated with chronic respiratory symptoms among woodwork workers. The geometric mean (GM) of dust exposure level among woodworkers was 10.27 mg/m3, which exceeded the limit of 10 mg/m3 set by the ACGIH. High prevalence of chronic respiratory symptoms was reported from woodwork factory workers. Increased work- experience, using bio-fuel as an energy source for cooking, past occupational dust exposure history, and having no occupational safety and health training were identified risk factors. The measured average personal wood dust exposure level was above the recommended occupational threshold limit value. Therefore, workers’ wood dust exposure reduction and control methods and respiratory health awareness programs should be implemented.
