Evaluation of elderly persons' functionality and care needs.

Objective: To evaluate the elderly persons' functionality, based on the International Classification of Functionality.
Methods: a cross-sectional, descriptive study; a stratified random sample of 903 elderly persons; a confidence level of 95%; and a margin of error of 2.5%. Questionnaire based on the International Classification of Functionality; data was collected based on structured interviews undertaken by health professionals in the health centers in the Alentejo region of Portugal.
Results: 30.7% of the elderly persons stated that they were illiterate, and 22.9% lived alone. Feeding/dietary (18.7%), housing (19.2%) and health needs (26.0%) were not met. Orientation functions were maintained in 83.4%; 58% of the elderly persons referred to pain so intense that it required care; 73.3% of the elderly persons did not have functional dentition. Levels of performance were superior to 80% in the participation activities: washing oneself (82.6%), toileting (92.2%), dressing, eating, and drinking (89%).
Conclusion: although a progressive decline in functionality is observed as age advances, the majority of dimensions are preserved until around 75 years of age.
