Objective:
To estimate the prevalence of asthma in workers by occupation in Washington State.
Methods:
Data from the 2006-2009 Behavioral Risk Factor Surveillance System (BRFSS) and the BRFSS Asthma Call-Back Survey (ACBS) in Washington State (WA) were analyzed. Using state-added and coded Industry and Occupation questions, we calculated prevalence ratios (PRs) for 19 occupational groups.
Results:
Of the 41,935 respondents who were currently employed during 2006-2009, the prevalence of current asthma was 8.1% [95% confidence interval (CI) 7.8-8.5%] When compared with the reference group of executive, administration and managerial occupations, three occupational groups had significantly (p < 0.05) higher PRs of current asthma: "Teachers, all levels, and Counselors' (PR 1.3, 95% CI 1.1-1. 6%); 'Administrative Support, including Clerical" (PR 1. 5, 95% CI 1.2-1.9%); and "Other Health Services" (PR 1.5, 95% CI 1.2-1.9). Half of the 2511 ACBS respondent workers (55.1%) indicated that they believed exposure at work had caused or worsened their asthma, but only 10.7% had ever spoken with a health care professional about their asthma being work related.
Conclusions:
Some occupations have a higher prevalence of current asthma than other occupations. The systematic collection of industry and occupation data can help identify worker populations with a high burden of asthma and can be used to target disease prevention efforts as well as to aid clinician recognition and treatment. Workers indicated that work-related asthma exposures are not discussed with their health care provider and this communication gap has implications for asthma management.
