Hypothesis
Does daytime activity influence the relationship between sleep efficiency and mortality in older adults?
Conclusion
Daytime activity reduces the risk of mortality associated with poor sleep efficiency in older adults.
Supporting Evidence
- Low average sleep efficiency was linked to a higher risk of mortality.
- High irregularity in sleep efficiency was also associated with increased mortality risk.
- Daytime activity was found to attenuate the risks associated with poor sleep efficiency.
Takeaway
Getting enough activity during the day can help older people sleep better and live longer.
Methodology
The study used Cox Proportional Hazard models to analyze data from wrist-worn accelerometers over approximately 9 years.
Participant Demographics
Older adults from the UK Biobank.
