Determinant factors of functional status among the oldest old.
BACKGROUND
The fastest-growing age group in Brazil and around the world is the oldest-old group (aged 80 and over). Among these individuals, the prevalence of disability and morbidity is higher than in other groups.


OBJECTIVE
To investigate the influence of socioeconomic, demographic, biological, health, nutritional, and social factors, as well as perceived health, on the functional status of the oldest old.


METHODS
This was a cross-sectional population-based study in which the data were collected by means of questionnaires and anthropometric measurements. The functional status was evaluated according to the model developed by Andreotti and Okuma (1999). Univariate and multivariate analyses were used.


RESULTS
The independent factors associated with worse functional status were: age 85 years and over (OR=2.91), female gender (OR=0.69), continuous use of five or more medications (OR=2.67), no visits to friends and/or relatives at least once a week (OR=11.91), and worse perceived health relative to peers (OR=4.40).


CONCLUSIONS
The results suggest that functional status is associated with a complex web of multidimensional factors. Thus, it is important to develop programs related to the factors that are susceptible to intervention in order to provide a better quality of life to the oldest old.
