Hypothesis
Sensor-derived mobility metrics and total daily physical activity are independently associated with mobility disability.
Conclusion
Mobility metrics can help link a more active lifestyle to reduced mobility disability.
Supporting Evidence
- Mobility metrics were significantly related to both prevalent and incident mobility disability.
- The association of total daily physical activity with mobility disability was reduced when mobility metrics were included.
- Mobility metrics mediated a significant portion of the relationship between total daily physical activity and mobility disability.
Takeaway
This study found that how well people move and how active they are can affect their ability to get around as they age.
Methodology
Mobility metrics were derived from sensors worn by participants, and associations with mobility disability were analyzed using logistic regression and Cox models.
Participant Demographics
Mean age 82 years, 77.4% female.
