“…Employees who have longer service years had higher odds of having respiratory symptoms. This finding was similar with studies done in Egypt [ 25 ] and India [ 24 , 26 ]. This result shows, the longer the duration of exposure to cotton dust the higher the presence of respiratory symptoms.…”

“…The prevalence of respiratory symptoms was higher in ginning, weaving, spinning and blowing departments. This finding is similar with studies done in Pakistan in 2015 [ 27 ] and in 2017 [ 28 ] and in Egypt [ 25 ]. This is due to the fact that worker in higher cotton dust exposure work environment such as blowing are more likely to develop respiratory symptoms than those workers with in administrative areas where there is less cotton dust exposure [ 18 ].…”

BackgroundCotton dust induced respiratory disorders are dramatically increased over the globe, especially the problem is serious in developing countries. Respiratory symptoms, such as cough, phlegm, wheezing, shortness of breath, chest tightness, chronic bronchitis, and byssinosis are common among workers exposed to cotton dust. However, in Ethiopia, the magnitude of the problem is not well known and information is limited about the risk factors. Therefore, this study was aimed to assess the prevalence of respiratory symptoms and associated factors.MethodsA Comparative cross-sectional study design was employed. A total of 413 (276 exposed and 137 unexposed) participants were included in the study. Stratified and simple random sampling techniques were used to select exposed and unexposed groups to cotton dust respectively. Multivariable binary logistic regression analyses was performed to identify variables associated with respiratory symptoms and adjusted odds ratio (AOR) was used to determine the strength of associations. Significance level was obtained at 95% confidence interval (CI) and p-value ≤0.05.ResultsThe prevalence of self-reported respiratory symptoms was 47.8% (95% CI: 41.3, 53.7%) and 15.3% (95% CI: 9.6, 22.3%) among exposed and control groups respectively. Sex (AOR = 2.1, 95% CI: 1.29, 3.45), service year (AOR = 2.38, 95% CI: 1.19, 4.71) and ventilation (AOR = 2.4, 95% CI: 1.17, 4.91) were factors significantly associated with respiratory symptoms. Furthermore, working department such as; ginning (AOR = 5.1, 95% CI: 2.13, 12.16), spinning (AOR = 4.96, 95% CI: 2.18, 11.29), weaving (AOR = 5.9, 95% CI: 2.46, 14.27) and blowing working departments (AOR = 5.14, 95% CI: 1.4, 18.94) were significantly associated with respiratory disorders.ConclusionsThe prevalence of self-reported respiratory symptoms was higher among workers exposed to cotton dust than unexposed workers. Sex, service year, working department and work unit ventilation were predictor variables for respiratory symptoms. Thus, reducing exposure to dust, adequate ventilation and improving the hygiene of working departments are needed to reduce respiratory symptoms.

“…The overall prevalence of chronic respiratory symptoms in this study (54%) was comparable to previous research conducted in similar low-and middle-income settings such as in Ethiopia (48%) [30], Egypt (59%) [9], Nigeria (62%) [11], and Bangladesh (53%) [31]. However, the prevalence was higher than the study conducted in an Iranian textile factory (26%), where workers were relatively younger [16].…”

“…Several previous studies have reported a higher prevalence of respiratory symptoms and a higher level of dust exposure in the first working phase of textile manufacturing, which is spinning [20,[32][33][34]. This leads many of the recent respiratory symptom studies in the textile industry to recruit study population from spinning or weaving or from both departments [4,7,9,30]. However, in the current study, the highest prevalence of chronic respiratory symptoms was reported among workers in the finishing department (71%).…”

“…A recent study from a textile factory in Ethiopia reported a high prevalence of chronic respiratory symptoms including cough (64.7%), chest tightness (43%), breathlessness (41%), and wheezing (39%) [7]. Studies in other parts of the world have also reported a higher prevalence of respiratory symptoms among textile workers than among controls [8][9][10][11]. Various studies [8,[12][13][14] have shown high exposure levels of dust and endotoxin in the textile factories, and the dust levels have been related to the development of respiratory symptoms [5,12,15].…”

Chronic respiratory symptoms and reduction in lung function has been described as a common health problem among textile workers in low- and middle-income countries. The objective of this study was to measure lung function and respiratory symptoms among workers from an integrated textile factory. A comparative cross-sectional study design with a cross-shift lung function measurement was performed in 306 cotton dust exposed workers from an integrated textile factory and 156 control workers from a water bottling factory. An integrated textile factory typically has four main production departments (spinning, weaving, finishing, and garment) that process raw cotton and manufacture clothes or fabrics. Respiratory symptoms were assessed by adopting the standard American Thoracic Society questionnaire. Descriptive statistics and logistic and linear regression analysis were used. The prevalence of respiratory symptoms was significantly higher among textile workers (54%) than in controls (28%). Chronic cough, chest tightness, and breathlessness were significantly higher among textile workers (23%, 33%, and 37%, respectively) than in the control group (5%, 17% and 6%, respectively). Breathlessness was the most prevalent chronic respiratory symptom with highest adjusted odds ratio 9.4 (95% CI 4.4–20.3). A significantly higher cross-shift lung function reduction was observed among textile workers (123 mL for FEV1 and 129 mL for FVC) compared with the control group (14 mL for FEV1 and 12 mL for FVC). Thus, workers’ respiratory health protection programs should be strengthened in textile factories.

Cotton and Other Textile Dusts

Byssinosis is an acute and chronic respiratory disease caused by occupational exposure to textile and vegetable dust. Characterized by chest tightness, it can occur after an absence from regular exposure to dust. Cotton production commonly leads to contamination with organic matter, and the endotoxin found in cotton dust is associated with an increased risk of byssinosis. Symptoms of chest tightness have also been observed with exposure to a variety of other organic dust, but this is not referred to as byssinosis outside of textile processing settings. To assess exposure to cotton dust, a standard air sampling of the inhalable or respirable dust fraction should be performed in the worker's breathing zone. Studies have also shown that exposure to vegetable dust can lead to an increased prevalence of nonspecific airway symptoms, modest cross‐shift declines in spirometry, and progressive declines in lung function among those with long exposure. Linear dose–response relationships have been observed between byssinosis prevalence, cross‐shift declines in FEV 1 , and concentration of inhalable cotton dust and endotoxin. Byssinosis is not a curable disease, and so far treatment interventions aim to reduce symptoms. Occupational exposure limit values for cotton dust have been continuously improved in several countries as a result of updated knowledge of the disease. Dust control is an important aspect of preventing lung disease among textile workers, but an integrated program including regulations, exposure risk assessment, health surveillance, and workplace health promotion activities are needed to protect workers' respiratory health.
