Hypothesis
The study aims to characterize novel physical activity metrics among older adults with varying cognitive statuses.
Conclusion
The study found that novel physical activity metrics, particularly PA complexity, may be more sensitive in identifying adults at early stages of dementia.
Supporting Evidence
- IWOC/SCC had fewer active bouts than NC (85.34 vs. 91.83, p=0.043).
- IWOC/SCC had lower PA complexity than NC (52.57% vs. 64.33%, p=0.001).
- MCI/AD had lower LTAC than NC (14.38 vs. 14.50, p=0.042).
- MCI/AD had higher activity fragmentation than NC and IWOC/SCC (25.89% vs. 23.70%, p=0.035).
- Each 1% higher in PA complexity was associated with 4% lower odds of IWOC/SCC compared to NC (OR=0.96, p=0.004).
Takeaway
This study looked at how active older people are and how it relates to their thinking skills. It found that some new ways to measure activity might help spot early signs of dementia.
Methodology
Participants wore accelerometers to measure physical activity and were classified based on cognitive status.

Mean age 65.3 years, 65.9% women.
