Work-related asthma: prevalence estimates by sex, age and smoking habits in a community sample
OBJECTIVE: To assess the prevalence of work-related asthma by sex, age and smoking habits.
DESIGN: The first phase, a mail questionnaire on asthma to a random sample of the general population of Hordaland County, Norway, gave a 90% response. A stratified sample of the responders (n = 1512) was invited to complete an occupational history questionnaire and performing spirometry and bronchial hyperresponsiveness. The attendance rate was 84%. Asthmatics were defined as having work-related asthma if they answered positively the questions: “Have you ever had respiratory symptoms in relation to your work? Did the symptoms improve on absence from work?”
RESULTS: The prevalence of work-related asthma was 0.9% in this population, constituting 28% of all asthmatics (95% confidence interval 25–31). The prevalence of work-related asthma was twice as high in men as in women, and did not differ significantly with age or between smoking groups.
CONCLUSION: Work-related asthma amounts to a significant proportion of total asthma in this population. This should be taken into account by health planners as it is by definition a preventable disorder.
