Objectives:
This study examined the prevalence and risk factors for asthma among farm and ranch operators in seven Midwestern States, using surveillance data from 2018, 2020, and 2023.
Methods:
Regression models were developed to identify predictors of asthma, including demographic factors, agricultural exposures, and physical activity.
Results:
The overall prevalence of asthma was 4.7%. Asthma was significantly associated with respiratory exposures to grain, feed, or hay dust (adjusted odds ratio [AOR], 2.14; 95% confidence interval [CI], 1.74-2.63) and animal confinement dust (AOR, 1.72; 95% CI, 1.35-2.21) after adjusting for demographics and work time on farm/ranch.
Conclusion:
The identified occupational risk factors highlight the importance of surveillance and targeted prevention among agricultural populations to further reduce the long-term respiratory exposures, particularly in animal confinement operations.

Asthma: Pathogenesis and Management
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
