    Abstract:
    Background: Although nurses are well described as being at risk of work-related asthma, certified nurse aides (CNAs) are understudied. Using a statewide registry in Texas, we measured prevalence and risk factors for work-related asthma and bronchial hyperresponsiveness (BHR) symptoms among CNAs. Methods: For this cross-sectional study, a questionnaire was mailed to a random sample of CNAs (n = 2,114) identified through the Texas Department of Aging and Disability Services registry, working in health care during 2016-2017, to collect data on job history, asthma symptoms, and sociodemographics. Two outcomes were defined: (a) new-onset asthma (NOA) after entry into the health care field and (b) BHR-related symptoms. Job exposures to cleaning compounds and tasks were assigned using an externally coded CNA-specific job-exposure matrix. Logistic regression modeling was used to measure associations between cleaning exposures and the two asthma outcomes. Findings: The final sample consisted of 413 CNAs (response rate 21.6%). The prevalence of NOA and BHR symptoms were 3.6% and 26.9%, respectively. In adjusted models, elevated odds for BHR symptoms were observed for patient care cleaning (odds ratio [OR] = 1.71, 95% confidence interval [CI] = [0.45, 6.51]), instrument cleaning (OR = 1.33, 95% CI = [0.66, 2.68]), building-surface cleaning (OR = 1.39, 95% CI = [0.35, 5.60]), exposure to glutaraldehyde/orthophthalaldehyde (OR = 1.33, 95% CI = [0.66, 2.68]), and latex glove use during 1992-2000 (OR = 1.62, 95% CI = [0.84, 3.12]). There were too few NOA cases to warrant meaningful regression analysis. Conclusion/Application to Practice: Although not statistically significant, we observed elevated odds of BHR symptoms among nurse aides, associated with cleaning exposures, suggesting this is an at-risk group of health care professionals for work-related respiratory disease, meriting further study.
