Abstract

Eur Respir J. 2013 Aug 15. [Epub ahead of print]

Occupational exposure is a well-recognized modifiable risk factor for asthma but the relationship between occupational exposure and asthma control has not been studied. We aimed to study this association among working-age adults from the European Community Respiratory Health Survey (ECRHS).Data were available for 7077 participants (in average 43 years, 45% never smokers; 5867 without asthma, 1210 with current asthma). Associations between occupational exposure to specific asthmagens and asthma control status (33% with uncontrolled asthma, based on the GINA guidelines) were evaluated using logistic and multinomial regressions, adjusted for age, gender and smoking status, with study areas included as a random effect.Statistically significant positive associations were observed between uncontrolled adult-onset asthma and both past 12-month and 10-year exposure to any occupational asthmagens (odds ratio (OR) [95% confidence interval]: 1.6[1.0-2.4], 1.7[1.2-2.5], respectively), high (1.7[1.0-2.8], 1.9[1.3-2.9]) and low (1.6[1.0-2.7], 1.8[1.2-2.7]) molecular weight agents, and cleaning agents (2.0[1.1-3.6], 2.3[1.4-3.6]), with stronger associations for long-term exposures. These associations were mainly explained by the exacerbation domain of asthma control and no associations were observed between asthmagens and partly-controlled asthma.These findings suggest that occupational exposure to asthmagens is associated with uncontrolled adult-onset asthma. Occupational risk factors should be quickly identified to prevent uncontrolled asthma.
