“…The geometric mean (GM) ± geometric standard deviation (GSD) of the overall personal wood dust concentration for the selected two woodwork factories was 10.27 (± 1.71) with a range varying from 4.28–26.40 mg/m 3 . This finding was consistent with the study conducted among workers in Tanzania [ 33 ]. But from this finding, we observed that the overall personal total dust concentration was higher than that of the previous study conducted in Tanzania [ 41 ], Ethiopia [ 14 ], and Sweden [ 42 ].…”

“…Having past occupational dust exposure history increased significantly woodworkers' risk of developing chronic respiratory symptoms. This study is in line with a study conducted in Tanzania, which stated that previous dusty jobs are three times more likely to have difficulty of breathing and breathlessness as the respiratory health symptoms than free from the previous dusty job [33]. This study is also similar to a study conducted in Ethiopia, which stated that workers who had past dust exposure history were 1.86 times more likely to have at least one chronic respiratory health symptoms than workers who had no past dust exposure history [28].…”

Background 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. Methods 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. Results 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. Conclusions 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.

Background Occupational respiratory diseases are major global public health problems, particularly for industry workers. Several studies have investigated occupational respiratory symptoms in various parts of Ethiopia. The findings have been inconsistent and inconclusive, and there is no nationally representative data on the subject. Therefore, this study aimed to estimate the pooled prevalence and factors associated with occupational respiratory symptoms among industry workers in Ethiopia (2010–2022). Methods Following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis framework Guidelines, search was conducted on several international databases including PubMed, CINAHL, African Journals Online, Hinari, Global Health, and Google scholar. The extracted data was analyzed using STATA 14. Random effect model was used to estimate the effect size. Egger regression test and I2 statistics were used to determine potential publication bias and heterogeneity, respectively among the reviewed articles. Results The meta-analysis included a total of 15 studies with 5,135 participants, revealing a pooled prevalence of 51.6% (95% CI: 43.6–59.6) for occupational respiratory symptoms among industry workers in Ethiopia. The absence of personal protective equipment (OR = 1.97, 95% CI: [1.17–3.32]), lack of occupational health and safety training (OR = 3.04, 95% CI: [2.36–3.93]), previous dust exposure (OR = 3.17, 95% CI: [2.3–4.37]), poor working environment (OR = 2.4, 95% CI: [1.7–3.2]), work experience greater than five years (OR = 4.04, 95% CI: [1.61–10.16]), smoking (OR = 6.91, 95% CI: [2.94–16.2]), and previous respiratory illness (OR = 4.25, 95% CI: [2.44–7.42]) were found to associate with the symptoms. Conclusions The high prevalence of occupational respiratory symptoms among industry workers in Ethiopia underscores the urgent need for effective interventions. The provision of personal protective equipment and improvement of working environments by the government, industry owners, and other stakeholders are crucial in reducing occupational respiratory symptoms. Additionally, prioritizing occupational health and safety training for industry workers can help prevent and mitigate the impact of occupational respiratory diseases. Registration This systematic review has been registered in the International Prospective Registry of Systematic Review (PROSPERO) with a specific registration number CRD42022383745.

“…Yet the usage of pieces of cloths in this study was (22.4%), which is lower than the study done in Tanzania (55.8%). 22 This difference may be due to a lack of awareness on the utilization of personal protective equipment while at work and lack of occupational health and safety training in the present study.…”

“…This study is similar to the study done in Tanzania among the sunflower oil industry, which stated that previous dusty jobs are three times more likely to have difficulty breathing and breathlessness as the respiratory health symptoms than free from the previous dusty job. 22 This evidence can be explained by the fact that workers with previous exposure ignore to use personal protective equipment because they think they adapt the dust. This statistical significance could be because the workers might have previously worked in dusty jobs identified to cause the respiratory problem, so this may lead to the aforementioned respiratory tissue physiologic change in later life and exacerbate the occurrence of respiratory symptoms.…”

Background: Flour mill workers are at high risk of developing respiratory symptoms due to exposure to flour dust in their working environment. Exposure to flour dust linked with the development of chronic respiratory disorders. However, very little evidence has been available on the respiratory symptoms of exposed workers in large-scale flour mill factories. Therefore, the aim of this study was to assess chronic respiratory health symptoms and associated factors among flour mill workers in Addis Ababa, Ethiopia. Methods: Cross-sectional study was conducted among a sample of 424 randomly selected workers from Addis Ababa flour mill factories. Respiratory health symptoms were assessed using an American Thoracic Society standard questionnaire customized with local context. Data were checked for completeness and Epi-Info V. 7.2 and SPSS V.21 statistical software were used for data entry and analysis, respectively. Multivariable logistic regression model was used to identify variables associated with chronic respiratory health symptoms. Variables that had significant association were identified based on adjusted odds ratio (AOR) with 95% confidence interval (CI) and p <0.05. Data were presented using tables, texts and figures. Results: The prevalence of chronic respiratory health symptoms among flour mill factory workers was 58.3% (95% CI: 53.7-63.4). Chronic respiratory health symptoms were significantly associated with age group (AOR=1.95, 95% CI; 1.17-2.79 and AOR=12.3, 95% CI; 4.39-34.6), monthly income (AOR=1.68, 95% CI; 1-2.79), work experience (AOR=2.58, 95% CI; 1-6.62), past dust exposure (AOR=1.86, 95% CI; 1.08-3.2) and utilization of respiratory protective equipment (AOR=2.29, 95% CI; 1.27-4.13). Conclusion and Recommendation: Chronic respiratory health symptoms were highly prevalent among flour mill factory workers. Supportive supervision and cooperation between Ministry of Labour and Social Affairs, flour mill managers and workers are needed to reduce exposure and improve working environment.
