Maintaining physical functioning (PF) in older women (ages 65-80) is key to preserving daily living independence after age 80. Factors like good health and no hip fracture history protect against decline.
Area of Science:
- Gerontology
- Public Health
- Epidemiology
Background:
- Examined physical functioning (PF) trajectories over 15 years in women aged 65-80.
- Identified protective factors for functional independence after age 80.
Purpose of the Study:
- To analyze physical functioning (PF) trajectories in older women.
- To determine factors predicting functional independence in late life.
Main Methods:
- Included 10,478 Women's Health Initiative extension participants (mean age 84.0).
- Assessed PF using SF-36 and functional independence in Activities of Daily Living (ADLs) and Instrumental ADLs (IADLs).
Main Results:
- Consistent PF maintenance predicts greater ADL and IADL independence in late life.
- Shared protective factors include maintained PF, excellent health, no hip fracture post-55, and no cardiovascular disease.
- Lower BMI (<25) and no depression uniquely predicted better IADL function.
Conclusions:
- Maintaining or improving PF from ages 65-80 significantly enhances late-life functional independence.
- Preventing injury and disease in older adulthood is crucial for sustained independence.
