title: A study of the prevalence of acute respiratory disorders among workers in the textile industry.
abstract: An epidemiological study of 774 workers in seven eastern France cotton textile factories was conducted to determine the prevalence of acute respiratory disorders. From nine non-textile companies, 464 workers, stratified as to sex, age and tobacco consumption participated in the study as a control population. A questionnaire designed to elicit the respiratory symptoms (in particular the Monday tightness characterizing byssinosis) was administered to the 1238 workers. Peak-expiratory-flow (PEF) measurement was made for each subject, exposed and non-exposed, before the start of the shift on the day of the worker's return to work and repeated at the end of the shift. The PEF's variations during the workshift were studied. Present Monday tightness was mentioned by 48 cotton exposed workers (6.2%) and by 9 non-exposed (1.9%) (P less than 0.001). A 10% decrease in PEF during the shift was present in 63 cotton exposed workers (8.1%) and in 10 non-exposed (2.1%) (P less than 0.001). For the exposed population, Monday tightness was analysed using multiple logistic regression, showing an absence of a link with smoking, an increased occurrence after 20 years of exposure (OR = 7.3) and a link with current job (more frequent among those with the dustiest jobs) (OR = 4.9). The multiple logistic analysis of a 10% decrease in PEF showed effects of smoking habits (OR = 1.86). It also showed a link with "highly polluted job" history (OR = 2.7), but especially with present job (OR = 3.4). The absence of a constant link between Monday tightness and drop of the PEF was found.
