“…This is supported by other studies where prolonged work experience is associated with a higher percent of occupational respiratory symptoms. 39,[51][52][53][54][55][56] This might be because as work experience is longer, the duration of dust exposure is higher. Long-term exposure to specks of dust or chemicals leads to higher deposition of dust to the respiratory tracts and of chronic inflammation that worsens breathing disorders manifested by different respiratory symptoms.…”

Introduction: Occupational respiratory symptoms are manifestations of respiratory diseases because of exposure to dust or chemicals such as asbestos, silicon and aluminium in the workplace like cement factory, tannery, textile and/or street sweeping, all of which affect the health condition and productivity. In Ethiopia, several primary studies were conducted regarding the magnitude of occupational respiratory symptoms with the prevalence of 68.89% in street sweepers and associated factors with inconsistent results. This meta-analysis aimed to pool the prevalence of respiratory symptoms and their associated factors among Ethiopian adults working in different workplaces. Methods: PubMed, African Journals Online, Google Scholar, Cochrane Library and Direct Google were systematically searched to identify primary studies. Two authors performed data abstraction and quality assessment for each included study independently. Cochran’s Q-statistic and I2 (I-squared) statistic were used to check heterogeneity. DerSimonian and Laird random-effects models were used to estimate the pooled prevalence and associated factors of respiratory symptoms. Publication bias was checked by funnel plot and Egger’s test, and also sensitivity analyses were performed. Results: Ten primary studies with 3441 study participants were included for the narrative synthesis and meta-analysis of the pooled prevalence of occupational respiratory symptoms. The pooled prevalence of overall occupational respiratory symptom was 54.58% (95% CI: 45.37–63.79). Dry cough was the most encountered respiratory symptom [34.93, 95% CI: 29.52–40.35], followed by breathlessness [28.67%, 95% CI: 20.13–37.22]. Work experience of over 5 years [OR = 2.24, 95% CI: 1.21–4.16] and educational level of Grade 8 and lower [OR = 1.28, 95% CI: 1.06–1.55] were significantly associated with occupational respiratory symptoms. Conclusion: In this review, the pooled prevalence of occupational respiratory symptoms was high. The findings of this study dictate the need for the implementation of workplace safety measures. Special attention is required to employees with lower educational level and longer duration of work experience. Prospero registration: CRD42020176826

“…Workers with greater than 5 years of work experience exhibited a higher prevalence of respiratory symptoms compared to the reference group. This is corroborated by additional research, which demonstrates that an extended period of work experience is linked to a greater proportion of respiratory symptoms related to one's occupation (19,20,21) . This could be attributed to the fact that as the duration of working experience increases, the amount of time exposed to dust also increases.…”

Objective To find the effect of aerobic exercises versus respiratory muscle training program on lung function among Quarry workers. Design: Randomized controlled trial. Subjects/Patients: Forty Quarry workers participated in the study Methods: Patients were randomly allocated to two groups. (Group A) were given aerobic exercises by engaging in a 30-minute session of walking on a treadmill, for eight weeks, three times a week. (Group B) were given a respiratory muscle training program using incentive spirometer in addition to aerobic exercise for eightweeks. A spirometer was used to do a pulmonary function test, which evaluated lung function by measuring Forced Vital Capacity (FVC), Forced Expiratory Volume in one second (FEV1), and the ratio of FEV1 to FVC. Results: Finding of this study indicated substantial improvement of FVC, FEV1 and FEV1/FVC after treatment in both groups values (P value= < 0.00001). there was significant difference between both groups after treatment regarding to FVC, FEV1, and FEV1/FVC with favored result in (Group B). Conclusion: Both groups showed a significant improved on lung function in favor to group B. So, this study proven that respiratory muscle training is an essential supplement to aerobic exercise for pulmonary rehabilitation to improve pulmonary functions in Quarry workers.

“…The relationships of occupational related respiratory symptoms and factors of workplaces, individual, and behavioral styles have been well established as well. Duration of exposure to high levels of flour dusts [ 8 , 11 ], sex, age, education, experience, and trainings in safety [ 17 , 18 ], and smoking [ 16 , 18 ] are among other factors that worsen the experience of work-related respiratory symptoms.…”

Background International Labour Organization (ILO) report indicates more than 2.4 million workers die from work-related diseases and accidents each year. Work-related respiratory ailments related to airborne particulate matter such as flour dust are responsible for about 386,000 deaths and 6.6 million illness-adjusted life years. Even though exposure to flour dust together with the extreme expansions of flour mill sectors is a priority health concern, extent of the problem is little investigated in Ethiopia. The aim of this study was to evaluate the magnitude and risk factors of work-related respiratory symptoms among flour mill workers in Bahir Dar City, Ethiopia. Methods This study employed a comparative cross-sectional survey of 560 samples (280 exposed group from flour mill workers and 280 unexposed group from office workers) with a stratified random sampling technique. The study was conducted from March to April 2019 in Bahir Dar City, Northwest Ethiopia. We used the British Medical Research Council (BMRC) questionnaire to assess work-related respiratory symptoms. The questionnaire was pretested and interview administered to collect data. Binary logistic regression analysis was fitted to evaluate significant factors of respiratory symptoms at a < 0.05 p value. Adjusted odds ratio (AOR) with a confidence interval (CI) of 95% was calculated to determine a strength of association. Results All the sampled participants had fully responded to the interview. The median age of exposed and unexposed groups was 28.5 interquartile range (IQR, 20) and 31 (IQR, 15) years, respectively. The prevalence of work-related respiratory symptoms among flour mill workers was substantially higher than that of among controls, 63.9% and 20.7%, respectively (Χ2 = 107.11; p < 0.0001). Chest illness among flour mill workers was higher, 43.6% (N = 122) compared to that of among control group, 7.9% (N = 22) followed by dyspnea, 33.6% (N = 94) versus 2.5% (N = 7) among flour mill workers and control group, respectively. Age > 35 years [AOR, 2.03; 95% CI (1.34, 5.48), having no education [AOR, 1.54; 95% CI (1.28, 3.06)], work set up with inadequate ventilation [AOR, 2.05; 95% CI (1.18, 3.56)], work experience > 5 years [AOR, 1.89; 95% CI (1.23, 4.67)] and having no training in safety [AOR, 2.45; 95% CI (1.45, 4.76)] significantly affected the experience of respiratory symptoms among flour mill workers whereas age [AOR, 1.79; 95% CI (1.06, 3.04)], monthly salary [AOR, 1.98; 95% CI (1.04, 3.78)] and exposure status [AOR, 5.18; 95% CI (3.34, 8.04)] were detected to be significant factors of respiratory symptoms in the exposed and the unexposed combined model. Conclusion Respiratory symptoms emanating from exposure to various flour dusts were significantly higher among flour mill workers than among the control group. Therefore, we recommend the need to effectively implement health and safety programs that account for the reduction of dust at a source, use of engineering controls (e.g., provision of adequate ventilation systems), use of administrative measures (e.g., training program and health surveillance) and provision of a suitable personal protective equipment (PPE). Furthermore, it is vital to integrate workplace health and safety programs to the wider public health policies and strategies to effectively mitigate the burden of work-related respiratory conditions. We also encourage future studies to evaluate concentration of flour dusts combined with physical examinations to establish plausible associations of respiratory symptoms with dusts of flour mill-related origin.
