Title Respiratory symptoms and cotton dust exposure; results of a 15 year follow up observation
Bibliographic information Dec. 2003, Vol.60, No.12, p.935-941. 42 ref.
Abstract The respiratory health of 429 Chinese cotton textile workers (study group) and 449 silk textile workers (control group) was followed from 1981 to 1996. Byssinosis, chest tightness, and non-specific respiratory symptoms were assessed by standardized questionnaires at four time points and exposures to cotton dust and endotoxin were estimated using area samples collected at each survey. Among cotton workers, the cumulative incidence of byssinosis and chest tightness was 24% and 23% respectively. No typical byssinosis was identified among silk workers and the incidence of chest tightness was 10%. Other respiratory symptoms were also more common among cotton workers. It was concluded that chronic exposure to cotton dust is related to both work specific and non-specific respiratory symptoms; byssinosis is more strongly associated with exposure to endotoxin than to dust. Cessation of exposure may improve the respiratory health of cotton textile workers, with the improvement increasing with time since last exposure.
