Bai C, et al. - Among 57,975 participants (aged 20-79 years) from the Shandong multicenter health check-up longitudinal study for Health Management, researchers investigated the association between blood eosinophil counts (BECs) and incident asthma by adjusting demographics and select relevant comorbidities (rhinitis, nasal polyps, pneumonia, bronchitis, and chronic obstructive pulmonary disease). To confirm the aforementioned association, multivariate modeling employed Poisson regression and Cox proportional hazards models. Findings revealed that a high BEC conferred risk for incident asthma, particularly when the BEC is > 110 cells/μL. Study findings, therefore, indicate that adults with high BECs may be more likely to develop asthma.
