Hypothesis
How does physical function predict activity levels in older adults?
Conclusion
The study found that changes in physical function are associated with variations in activity levels among older adults.
Supporting Evidence
- A steeper increase in ADL impairment was linked to more sitting time and fewer steps.
- A decrease in sPPF slope was associated with fewer steps and less moderate-to-vigorous physical activity.
Takeaway
As older people have more trouble with daily activities, they tend to sit more and move less.
Methodology
The study used linear mixed effects models and multivariable linear regression to analyze physical function and activity data.
Participant Demographics
Participants were 77.6 years old on average, 55% female, and 91% White.
