AIMS:
To estimate the prevalence of frailty and identify the associated factors in residents of homes for the aged of Southeast and Middle West regions of Brazil.
METHODS:
Sectional study with 442 institutionalized elderly in four Brazilian municipalities. Frailty was assessed using the Brazilian version of the Tilburg Frailty Indicator (TFI). The characteristics of the study population were described and the prevalence of frailty was estimated. Means of the total score of TFI and of the scores of its domains were verified. Poisson's regression was applied to explore the observed associations, after adjustment for confounding.
RESULTS:
The study population was predominantly male (64.3%) and schooled (74.1%) and mean age was 75.0 (9.9) years. Prevalence of frailty was 52.0%. The mean of TFI's total score was 4.9 (2.5) points and the means of domains physical, psychological and social were, respectively, 2.8 (1.7), 1.3 (0.9) and 0.8 (0.8). The following variables were associated with frailty in institutionalized elders: advanced age, illiteracy, comorbidity and polipharmacy. In the multivariate model, only the associations with illiteracy and comorbidity maintained statistical significance (PR=1.28 CI95% 1.07-1.54 and PR=1.48 CI95% 1.21-1.81).
CONCLUSIONS:
The prevalence of frailty was higher than the observed in two other studies that assessed this condition in institutionalized elders. The identified associations are corroborated by the scientific literature. The TFI is a multidimensional instrument based on an integral concept of frailty and the Brazilian version was adequate to evaluate this condition in institutionalized elders. However, it is important to conduct studies to assess its usefulness in elderly community residents.
