Joint association of lung function and physical activity with risk of incident stroke among the US and Chinese adults

Key Points

• This research aims to examine how lung function and physical activity together affect the risk of having a stroke.
• Cross-sectional analysis of data from US and Chinese adults
• Assessment of lung function and physical activity levels
• Evaluation of incident stroke risk through integrated factors
• Preserved lung function and regular physical activity significantly lower stroke risk
• Combined assessment enhances the effectiveness of stroke risk stratification
• Findings suggest targeted prevention strategies could be more effective in diverse populations
