Written in the December 2000 issue of the American Journal of Respiratory and Critical Care Medicine, Anthony R. Johnson, MD, formerly associated with the Vancouver General Hospital, University of British Columbia, along with eight colleagues, reported that over 18% of cases of adult-onset asthma in a Canadian urban population could have been prevented by eliminating exposure at work in combined high-risk occupations and industries.
Occupational asthma was defined as asthma originating from causes and conditions attributable to a particular occupational environment and not to stimuli encountered outside of the workplace.
The study participants consisted of 18,701 people from six communities in Canada, ranging in age from 20 to 44 years, who completed an initial questionnaire. From this group, 2,974 attended lab sessions where they completed a second questionnaire on symptoms and risk factors for asthma.
The researchers gathered detailed information on occupational history and exposure to 39 specific materials known to induce asthma. Then, trained lab technicians measured the ...
