Objective:

to estimate the prevalence of disability related to basic and instrumental activities of daily living and its association with socioeconomic, demographic, behavioral and health characteristics in the elderly.

Methods:

population-based cross-sectional study in Pelotas, Brazil, in 2014; Katz and Lawton scales were used to assess the outcomes using Poisson regression.

Results:

the study included 1.451 elderly individuals; the prevalence of disability for basic and instrumental activities was 36.1% and 34.0%, respectively, and 18.1% in both; higher prevalence of functional disability were observed individuals ≥80 years (PR=3.01; 95%CI 2.17;4.18), not working (PR=2.02; 95%CI 1.13;3.60) and those with multiple morbidities (PR=3.28; 95%CI 1.38;7.79); and lower in individuals with ≥12 years of schooling (PR=0.40; 95%CI 0.24;0.66), and that were physically active (PR=0.42; 95%CI 0.21;0.82).

Conclusion:

functional disability was associated to individuals older than 80, with less schooling years and affected by multiple morbidities.
