The STOP‑BANG score and lung function in a general population

Abstract

Background: Obstructive sleep apnea (OSA) commonly coexists with lung disease. However, the association between OSA components and lung function remains unclear. This study estimated STOP‑BANG scores according to lung function using nationwide Korean data. Materials and Methods: Three thousand and two hundred eighty adults with available STOP‑BANG scores and spirometry data were analyzed. Multivariate regression models were applied to estimate STOP‑BANG scores according to lung function. Results: Approximately 28% of participants had abnormal lung function, and the characteristics were diverse. The significant factors associated with abnormal lung function included the STOP‑BANG score. In multivariate regression analyses, individuals with abnormal lung function had significantly higher STOP‑BANG scores than those with normal lung function (odds ratio: 1.19; 95% confidence interval: 1.10–1.29; P < 0.001), and this difference was remarkable in men. Conclusion: Our results suggest that screening and management of OSA components are warranted to prevent impaired lung function.
