Implication

Randomized trial examines how different types of sedentary behavior affect cognitive function in older adults, suggesting implications for behavior optimization.

Key Points

This study aims to explore the associations between 24-hour movement behaviors and cognitive function in older adults.
Data collected from 2516 US adults aged ≥ 60 years using wrist-worn accelerometry for activity assessment.
Cognitive function evaluated through standardized tests: memory, language, and executive function.
Weighted compositional linear regression and isotemporal substitution models applied for analysis.
Greater relative time in moderate-to-vigorous physical activity (MVPA) associates with higher global cognition (β = 0.191, P ≤ 0.001).
Computer use positively impacts cognitive domains (global: β = 0.045, P < 0.001), while TV watching negatively affects cognition (β =−0.050, P = 0.047).
Reallocating time to MVPA or computer use predicts higher global cognition scores, emphasizing the importance of active behaviors.
