“…As developing countries expand their textile industries, reports of byssinosis in- crease. Such reports have come from Egypt (8), Sudan (17), Tanzania (26), and Hong Kong (25). This report describes the first epidemiologic study of cotton textile workers in China using diagnostic criteria and equipment similar to those used in the United States and Great Britain.…”

[40][41][42][43][44][45]. The prevalence of byssinosis and nonspecific respiratorysymptoms was studied in 887 textile workers with at least two years of employment in two cotton mills and one silk mill in Shanghai, the People's Republicof China. A standardized respiratory questionnaire was used, and environmental sampling was performed with vertical e1utriatorsand colorimeter grading. Eight percent of the cotton textile workers complained of byssinosis. The reports of byssinosiswere mostly mild (grade 1/2), more prevalent among women, and unrelated to duration of employment or elutriator dust levels. Nonspecific respiratory symptoms were significantlymore prevalent among cotton textile workers than silk workers. After adjustment for age, gender, and smoking in logistic regression models, the odds ratios for the effect of working in cotton textile mills on chronic bronchitis, chronic cough, and frequent chest illness were 3.3, 2.9 and 4.7, respectively. Although none of the symptoms were related to current dust levels, the range of exposures was narrow, and information was only available on current levels of cotton dust. This study represents the first respiratory survey of the textile industry in China using diagnostic criteria similar to that used in the United States and England; it defines a cohort for prospective investigation.

“…5,8 In Tanzania, little is known about the prevalence of byssinosis and it is not clear which risk factors are associated with byssinosis because the last study in Tanzania was done almost 40 years ago 1979. 9 In order to develop effective control measures, it is important to understand the magnitude of the problem and risk factors associated with byssinosis among textile workers. Therefore the aim of this study was to assess the cotton dust exposure, prevalence of byssinosis and associated factors so as to portray the clear health status of workers in textile industry in Dar es Salaam.…”

Background: Cotton dust exposure increases the risk of developing lung diseases including Byssinosis. The prevalence of byssinosis is more in developing countries compare to developed countries. For the past forty years there are little information known about the prevalence of byssinosis and its associated risk factors among textile workers in Tanzania. Objective: The study aimed to assess dust exposure and associated risk factors among textile workers, in Dar es Salaam, Tanzania. Material and methods: The study design was descriptive cross sectional study conducted from March to August 2019. Stratified sampling technique was used to obtain 325 participants (exposed 164 and control 161) respectively. A modified British Medical Research Council (BMRC) questionnaire and Side Kick Casella Pump were used for data collection. Data were analyzed using Statistical Package for Social Science software 23 versions. Chi square test and Binary logistic regression were performed to check for association. A 95% confidence Interval with a significance expressed in P˂0.05 was used. Results: Prevalence of byssinosis in the exposed group was 18.9% and 6.2% in the control group. Respiratory symptoms such as Coughing more days in three consecutive months (P˂0.001), wheezing (P˂0.02), dyspnoea I (P˂0.03), dyspnoea II (P˂0.007), and dyspnoea III (P˂0.002), were higher among exposed group compare to control group and the differences were statistically significant. The department of weaving had higher dust level of arithmetic mean of 2.20 mg/m3 (SD =0.32). Working experience (P˂0.02), previously respiratory symptoms (P˂0.001), were significant risk factors for byssinosis. Conclusion: In conclusion, our study shows that workers who are exposed cotton dust have higher prevalence of byssinosis and other respiratory symptoms. Awareness of the byssinosis disease, and necessary preventive measure need to be highlighted among stakeholders.

“…The importance of using a virgin population for such a study can be seen from reports by Mustafa and Bouhuys [Mustafa et al, 1979;Bouhuys et al, 1969). Mustafa examined 216 textile workers and found, for those employed less than 5 years, 211 161 (13%) had byssinosis, a prevalence that was somewhat lower than among those employed longer.…”

Epidemiologic approaches to improved understanding of the several reactions observed in cotton processors began in 1955 with Schilling's symptom classification of Monday-morning chest tightness. To date, epidemiologic studies have identified the importance of increasing years of exposure to the development of both specific and nonspecific chronic respiratory symptoms and of acute change in pulmonary function. The few longitudinal studies suggest similar associations with accelerated loss of pulmonary function. Respirable dust level has been associated, cross-sectionally, with symptoms and with acute function change, but studies have not yet been made with sufficient prospective collection of both exposure and health effects data to estimate accurately the association of continued exposure with accelerated loss of lung function or development of disability. Furthermore, there has been very limited field study comparing exposure to respirable dust distinguished from exposure to endotoxin. With careful attention to features of study design and analytic plans, investigators can take advantage of simple technology to examine the fate of the acute responder, the potential for recovery if exposure is reduced or ceased, and the long-term dose response relationship between different cumulative measures of exposure and chronic disease.
