Strength and ability to implement the activities of daily living in elderly resident in rural areas

Objective: To examine the association between muscle strength and the ability to perform basic and instrumental activities of daily living in elderly resident in rural areas of Jequie, Brazil. Methods: We performed a cross-sectional design study with a population of 104 individuals aged sixty or older, registered in the Family Health Unit of the district of Itajuru, Jequie-Brazil. Data collection was performed using a standardized instrument used as an interview, followed by the application of tests (bending arm with dumbbell and rising from a chair 30 sec). The basic and instrumental activities of daily living were investigated through the Katz and Lawton scales, respectively. The chi-square test with p < 0.05 was used as a measure of statistical significance for bivariate analyzes between muscle strength and ability to perform daily activities. Results: The results showed a significant association between muscle strength and dynamic ability to perform activities of daily living. Conclusion: Reduced muscle strength is an important predictor of the functional ability of the elderly. Accordingly, it is recommended to observe muscle strength in actions directed at the elderly.
