Subjective Age in the Oldest Old: What is the Association with Disability and Sensory Impairment?

Disability and sensory impairment are particularly pronounced among the oldest old population (80 years and older). Considering these specificities, we analyzed the association of such parameters with subjective age, a strong predictor of health-related outcomes. We assumed that greater disability and sensory impairment (hearing and visual) would be linked with an older subjective age.

Prospective population-based study.

Data were gathered from the 27^th year follow-up of the PAQUID cohort, visit where the question on subjective age was collected. Our sample included 75 participants older than 93 years, with a mean age of 96 years.

Disability was assessed with Activities of Daily Living and sensory impairments by asking participants if they have visual or hearing difficulties. A multiple linear regression model was performed with subjective age as the dependent variable. Independent variables were functional disability and visual and hearing impairments.

On average, the participants felt 12 years younger than their actual age. Multiple regression analyses controlled for age, gender, education, depression, and dementia indicated that self-reported hearing loss (p = 0.03) was associated with an older subjective age, whereas no significant associations were observed for disability (p = 0.42) and self-reported visual loss (p = 0.18).

Hearing impairment, in contrast to visual impairment and disability, is associated with feeling older. These results are discussed in light of health consequences and age stigma carried by hearing impairment.
