Prevalence and Risk Factors of Work-Related Asthma in Hospital Cleaning Workers

OBJECTIVE:

 This study aimed to determine the prevalence and evaluate the risk factors of work-related asthma among professional hospital cleaning workers.

MATERIAL AND METHODS:

 In total, 278 cleaning workers were interviewed (response rate: 75.7%), and pulmonary function tests were performed. The presence of asthma and its work-relatedness was evaluated. Serial peak expiratory flow measurements were planned according to symptoms increased at work or spirometric findings.

RESULTS:

 Totally 40 cleaning workers had asthma (14.3%); of these, 17 (6.1%) had work-related asthma, and 23 (8.2%) had non-work- related asthma. Non-work-related asthma and work-related asthma were significantly associated with the females(odds ratio 95% CI: 3.0, 1.1-8.4, and 3.2, 1.0-10.3, respectively). Non-work-related asthma was significantly associated with a family history of asthma (odds ratio 95%CI: 5.1, 2.0-13.2 and 2.8, 0.99-7.9, respectively) and limescale remover use at work (odds ratio, 95% CI: 0.21, 0.04-0.97, and 1.7, 0.5-5.2, respectively). Only 7 (28.0%) of 25 cleaning workers who were suggested serial peak expiratory flow measurements could complete the measurements. Of those, measurements of 2 cleaning workers were consistent with occupational asthma.

CONCLUSION:

 The negative association between limescale remover use at work and non-work-related asthma suggested health selec- tion bias (avoidance behavior) due to the asthmatic effects of these chemicals.
