Association between occupational dust exposure and asthma prevalence in a nationally representative US population

ObjectiveThis study sought to examine the relationship between exposure to different types of workplace dust (mineral dust, organic dust, exhaust fumes, and other fumes) and the prevalence of asthma in a nationally representative sample of the population in the United States.MethodsUsing data from the National Health and Nutrition Examination Survey 2007-2012, we analyzed data of 16,841 participants after exclusions based on specific criteria. Logistic regression models were used to evaluate the association between dust exposure and asthma prevalence after adjusting for demographic and health-related covariates.ResultsOur findings indicate that exposure to various types of dust is positively associated with the prevalence of asthma. This association remained significant after adjusting for age, sex, race, and other covariates. Notably, subgroup analysis revealed that females are more susceptible to asthma from dust exposure than males. In addition, individuals with higher body mass index and older age are more likely to have asthma due to dust inhalation.ConclusionThis study underscores the need for targeted occupational health interventions and policies, especially for high-risk groups such as females, those with higher body weight, and older individuals. Further longitudinal studies are recommended to establish causal relationships.
