Independent and joint association of accelerometer-measured sedentary behaviour and physical activity with mild cognitive impairment and intrinsic capacity decline among Chinese older adults: study protocol for a cross-sectional study
Cross-sectional study explores sedentary behaviour and physical activity effects on cognitive function and intrinsic capacity in older adults, suggesting significant associations.
Key Points
Sedentary behaviour correlates with higher risk of mild cognitive impairment in older adults, while physical activity may provide protective effects.
Participants aged 65 and older will be monitored using accelerometers for a week to measure their activity levels and sedentary time.
Cross-sectional observational design will analyze the joint impact of sedentary behaviour and physical activity on cognitive decline across different age groups.
Findings may indicate the need for targeted interventions to enhance intrinsic capacity and cognitive health among older populations.
