Association between oxidative balance score and lung function and FeNO and mortality in the US population

In this study, OBS, lifestyle OBS, and dietary OBS levels were positively correlated with lung function parameters (FEV1, FVC and PEF) in U.S. adults. Exploring this association can enhance our understanding of how oxidative homeostasis influences lung function changes. This could provide valuable interventions for lung function decline. We also found that higher OBS was associated with lower all-cause mortality. Adopting a healthy lifestyle and consuming an antioxidant-rich diet may significantly improve the prognosis of patients by reducing oxidative stress-related damage.
