Work-Related Asthma and Its Impact on Quality of Life and Work Productivity.

Background: The impact of work-related asthma (WRA) on quality of life (QoL) and work productivity remains largely neglected/uncertain despite its high prevalence.
Objective: To investigate the association of WRA with QoL and work productivity as compared with subjects with non-WRA and those without asthma and rhinitis.
Methods: A cross-sectional survey was carried out among workers during their periodic occupational health visit in Belgium. The Mini Asthma Quality of Life Questionnaire, the 8-item Medical Outcome Study Short Form instrument, and the Work Productivity and Activity Impairment-General Health questionnaire were administered. Survey participants were divided into 3 groups: (1) WRA (current asthma with ≥2 respiratory symptoms at work; n = 89); (2) non-WRA (current asthma without work-related respiratory symptoms; n = 119); and (3) the reference group (no asthma and no lower respiratory, nasal, or eye symptoms; n = 815). Associations of QoL and work productivity with WRA were evaluated by multivariable regression analyses.
Results: WRA and having poor asthma control were significantly associated with lower global Mini Asthma Quality of Life Questionnaire scores compared with non-WRA. Asthmatic subjects had significantly lower physical and mental health component scores of the 8-item Medical Outcome Study Short Form instrument and overall work productivity compared with the reference group, with greater impairment in workers with WRA than in those without WRA. Moreover, workers with WRA had higher percentages of doctor visits and income reduction because of respiratory symptoms than those with non-WRA. Work-related rhinitis and depression were associated with reduced QoL, independent of the effect of WRA.
Conclusions: WRA should be managed comprehensively to reduce the worsening of QoL and work productivity of those affected.
