Assessing Functional Capacity and Factors Determining Functional Decline in the Elderly: A Cross-Sectional Study

The aim of this study is to assess functional capacity and determine the factors associated with functional decline in the elderly in adult day care centres and home care support in the County of Coimbra, Portugal.

Cross-sectional study. A total of 115 participants of both genders, aged between 65 and 98, were enrolled in the home care support and adult day care system of the County of Coimbra, Portugal. Functional capacity was assessed using the Barthel index and the Lawton index. Another questionnaire gathered social, demographic and health status information.

The basic activities of daily living were significantly associated with age, cohabitation, medication usage, falls and multiple morbidity. Analysis of the study's variables and the instrumental activities of daily living found significant associations between age, institutional affiliation, perceived health status, hospitalizations, medication usage, physical exercise, multiple morbidities, falls, and fall prevention.

The results demonstrate that no statistically observable differences were found between gender and functional dependence. A significant association between the Barthel index and cohabitation was also found. We should also highlight that this sample revealed the extremely important role of families in determining the protection of highly dependent older people. Likewise, a significant association was observed between instrumental activities of daily living and levels of physical activity in which greater independence was found in those seniors who practiced physical exercise three or more times per week.

The results of this study allow us to identify factors that may be associated with the functional decline in the elderly. Useful evidence for the adoption of intervention strategies in the elderly population was added, focused on the prevention of functional decline and maintenance of the functional capacities of the elderly.
