Physical Activity and Mortality in Older Adults with Dementia
Author Information
Author(s): Burch Brittany, Resnick Barbara
Primary Institution: University of Maryland Baltimore
Hypothesis
Greater amounts of physical activity at one month post discharge is associated with lower mortality over the first year post discharge.
Conclusion
The study found no statistically significant association between physical activity one month post discharge and mortality within one year, but there was a strong trend suggesting increased physical activity may reduce mortality risk.
Supporting Evidence
- Participants spent 83.3% of their days sedentary after hospitalization.
- The study suggests a trend where increasing physical activity by 10 minutes daily may decrease mortality risk by 4%.
Takeaway
Older adults with dementia who are more active after leaving the hospital might live longer, but this study didn't find strong proof of that.
Methodology
The study used MotionWatch8 accelerometers to measure physical activity and logistic regression to analyze the data.
Limitations
The sample size was small, which may limit the generalizability of the findings.
Participant Demographics
Recently hospitalized older adults with dementia.
