The prevalence of byssinosis was 37% among Khartoum spinners where coarse cotton was processed, significantly higher (p&lt;0.01) than the 1% found among Hassaheisa spinners, where fine cotton was used. The prevalence of chronic bronchitis was 29% in Khartoum and 2% in Hassaheisa spinners. A significant reduction in forced expiratory volumes (FEV<jats:sub>1<\/jats:sub> after a shift) was observed in spinners of both factories. Our findings provide evidence that very low rates or absence of byssinosis, related respiratory symptoms, and significant functional abnormalities (FEV<jats:sub>1<\/jats:sub>) in the late stages of cotton yarn processing all depend on the quality of cotton used and low levels of cotton dust concentration.<\/jats:p>","DOI":"10.1002\/ajim.4700120305","type":"journal-article","created":{"date-parts":[[2007,4,17]],"date-time":"2007-04-17T03:47:37Z","timestamp":1176781657000},"page":"281-289","source":"Crossref","is-referenced-by-count":12,"title":["Prevalence of byssinosis and respiratory symptoms among spinners in sudanese cotton mills"],"prefix":"10.1002","volume":"12","author":[{"given":"Mohamed A.
