[Healthy aging and functional disability among the elderly inhabitants of the Canary Islands (Spain)].
BACKGROUND
Among the elderly, health is usually measured in terms of ability for both the Basic and Instrumental Activities of Daily Living. The objective of this work is to estimate the percentage of healthy elderly among the population of the Canary Islands (Spain) and the factors associated with functional disability in this older population.


METHODS
We randomly sampled 411 elderly from the whole population of the Canary Islands, of whom 97 had died or could not be located. Of the 314 people approached, 29 (9.2%) denied participation. The 285 participants were interviewed with the Spanish version of Pfeiffer's Functional Assessment Inventory previously adapted and validated in our habitat.


RESULTS
Up to 53% of the elderly (61% of males and 47% of females) were disability-free. Greater disability was associated with higher age, lesser education, worse subjective health, worse subjective vision, and worse subjective hearing. No association of disability with female gender and cognitive deficit was found when including age and education in the logistic model.


CONCLUSIONS
Health status among the elderly in the Canaries is similar to that in developed countries. In contrast with other studies, we found functional ability associated with poor hearing and dissociated from cognitive deficit.
