Summary
Older adults in China who sleep less than 7 hours or more than 7 hours per night face a higher risk of functional disability. Optimal sleep duration for this age group is crucial for maintaining daily activities and overall health.
Area of Science:
- Gerontology
- Sleep Science
- Public Health
Background:
- Sleep duration is vital for physiological functions and health in older adults.
- Limited research exists on the link between sleep duration and functional disability in China's elderly population.
Purpose of the Study:
- To investigate the association between sleep duration and functional disabilities in Chinese adults aged 65 and above.
- To identify optimal sleep durations for reducing functional disability risk in the elderly population.
Main Methods:
- Cross-sectional study using data from the 2018 China Health and Retirement Longitudinal Study (CHARLS).
- Sleep duration assessed via face-to-face interviews; functional disability measured using Activities of Daily Living (ADL) and Instrumental Activities of Daily Living (IADL) scales.
- Multivariable generalized linear models and restricted cubic-spline models analyzed the dose-response relationship.
Main Results:
- 5519 participants (mean age 73.67 years) were analyzed, with 50.73% experiencing functional disability.
- A U-shaped association was observed: shorter (≤6 hours) and longer (≥8 hours) sleep durations increased functional disability risk compared to 7 hours.
- Both insufficient (<7 hours) and excessive (>7 hours) sleep were linked to significantly higher risks of functional disability (ORs 0.85 and 1.16, respectively).
Conclusions:
- Sleep durations deviating from 7 hours are associated with increased functional disability risk in older Chinese adults.
- Further research into sleep duration improvement strategies is recommended to mitigate functional disability.
- Maintaining a 7-hour sleep duration may be beneficial for functional independence in the elderly.
