Objective: To identify factors associated with health care professional–diagnosed work-related asthma (WRA) among adults who describe their asthma as being caused or made worse by workplace exposures (possible WRA).
Methods: We calculated prevalence ratios adjusted for age and sex using data from the 2006 to 2008 Behavioral Risk Factor Surveillance System Asthma Call-Back Survey from 37 states and the District of Columbia for ever-employed adults with current asthma and possible WRA.
Results: An estimated 17.6% of ever-employed adults with current asthma and possible WRA had health care professional–diagnosed WRA. Health care professional–diagnosed WRA was associated with age, income, employment status, asthma control level, asthma attack, emergency department visit, hospitalization, urgent treatment, and changing/quitting a job due to asthma.
Conclusions: Among ever-employed adults with possible WRA, health care professional–diagnosed WRA is associated with poorer asthma control and frequent unscheduled health care visits.
