Frailty and Autonomy among the Oldest Old: Evidence from the Multicenter Prospective AgeCoDe-AgeQualiDe Study

Area of Science:

• Gerontology
• Psychology
• Public Health

Background:

• Limited research exists on the relationship between perceived autonomy and frailty in the oldest old.
• Understanding this link is crucial for promoting healthy aging in advanced years.

Purpose of the Study:

• To investigate the association between perceived autonomy and frailty in individuals aged 85 and older.
• To identify factors associated with autonomy in this demographic.

Main Methods:

• Utilized data from the AgeQualiDe prospective cohort study (n=510, mean age 90.3 years).
• Assessed frailty using the Canadian Study of Health and Aging (CSHA) Clinical Frailty Scale (CFS).
• Measured perceived autonomy using the Schwarzer autonomy scale, controlling for covariates.

Main Results:

• Lower perceived autonomy was significantly associated with higher frailty levels across the total sample, women, and men (p < 0.001).
• Perceived autonomy was also linked to fewer depressive symptoms, less cognitive impairment, and lower rates of institutionalization.
• No significant associations were found with age, sex, marital status, education, or social support.

Conclusions:

• Frailty is demonstrably associated with lower perceived autonomy in the oldest old.
• Health-related factors, rather than sociodemographic ones, were consistently linked to autonomy.
• Maintaining autonomy is critical for both physical and mental well-being in very old age.
