Respiratory symptoms and lung function tests in an African jute factory workers.

A survey of respiratory symptoms were carried out among 200 female and 734 male workers in the Jute Factory at Kumasi. Dust concentration was also measured in various sections of the factory. The Batching and Preparing sections of the factory were the most dusty areas. Respiratory symptoms were commoner (or worse) in those working in dusty areas of the factory than office workers who work in a relatively clean environment. Occurrence of symptoms was related to degree but not the duration of exposure. Prevalence of symptoms was not influenced by age or sex but was increased by smoking. Cough, and sputum were the commonest symptoms. There were no significant objective signs of airways obstruction. Monday tightness and wheeze were rare complaints among the jute workers.
