Summary
Dynapenic abdominal obesity (DAO) combined with either short or long sleep durations significantly increases the risk of functional disability in older Chinese adults. Managing sleep patterns and body composition is key for prevention.
Area of Science:
- Gerontology
- Public Health
- Epidemiology
Background:
- Dynapenic abdominal obesity (DAO) is a growing concern in aging populations.
- Abnormal sleep durations are increasingly linked to adverse health outcomes.
- Understanding the interplay between DAO and sleep is crucial for geriatric health.
Purpose of the Study:
- To investigate the combined effect of dynapenia, abdominal obesity, and sleep duration on functional disability risk.
- To analyze interactions between DAO and sleep patterns in middle-aged and older Chinese adults.
Main Methods:
- Retrospective cohort study using data from the China Health and Retirement Longitudinal Study (2011-2020).
- Included 6,343 participants, assessing sleep duration via interviews.
- Dynapenia and abdominal obesity defined by handgrip strength and waist circumference; functional disability by activities of daily living.
- Cox proportional hazard models used to analyze interactions.
Main Results:
- Over 10 years, 61.2% of participants developed functional disability.
- Short or long sleep durations combined with DAO significantly elevated functional disability risk (RR 1.42-1.63).
- Significant interactions observed between short sleep and DAO components; middle-aged females and elderly males showed differential susceptibility.
Conclusions:
- Both short and long sleep durations exacerbate the risk of functional disability when co-occurring with dynapenic abdominal obesity.
- Interventions targeting waist circumference and grip strength in individuals with abnormal sleep are recommended for functional disability prevention.
