0139/2022 - Physical frailty, activity limitation and mortality in older Brazilians: longitudinal findings of the FIBRA-BH study (2009-2019). Physical frailty, activity limitation and mortality in older Brazilians
Objetivo: Investigar a associação longitudinal entre fragilidade física e mudança no perfil de limitação para realizar as atividades básicas e instrumentais de vida diária (ABVD e AIVD) e mortalidade em 10 anos em idosos comunitários brasileiros. Métodos: Um estudo longitudinal foi conduzido com dados do Estudo de Fragilidade em Idosos Brasileiros (FIBRA), 2009-2019. Fragilidade física foi categorizada em vulnerabilidade (pré-frágil e frágil) e robustez. Limitação para realizar ABVD e AIVD foi avaliada pelo Índice de Katz e Escala de Lawton-Brody. Modelos de equação de estimação generalizada e de riscos proporcionais de Cox foram usados na análise dos dados. Resultados: Dos 200 idosos avaliados em 2009, 139 foram localizados em 2019. Destes, 102 foram entrevistados e 37 óbitos foram registrados. A chance dos idosos vulneráveis no momento 1 serem dependentes nas ABVD no momento 2 foi de 4,19 vezes a chance dos idosos robustos. Para as AIVD, a chance dos idosos vulneráveis no momento 1 serem dependentes no momento 2 foi de 3,12 vezes a chance dos idosos robustos. A análise de Cox mostrou que o risco de morte entre os idosos vulneráveis foi 2,50 vezes o risco dos idosos robustos. Os resultados reforçam a importância do acompanhamento e intervenção precoce para prevenir a fragilidade.

Abstract:
Objective: To investigate the longitudinal association between physical frailty and change in the profile of limitation to perform basic and instrumental activities of daily living (BADL and IADL) and mortality in a 10-year period in Brazilian community-dwelling older people. Methods: A longitudinal study was conducted with data from the Frailty in Brazilian Older People (FIBRA) study, 2009-2019. Physical frailty was categorized into vulnerability (pre-frail and frail) and robustness. Limitation in BADL and IADL was assessed by the Katz Index and Lawton-Brody Scale. The generalized estimating equation and the Cox proportional hazards models were used in the data analysis. Results: Out of 200 older people evaluated in 2009,139 were located in 2019. Of these, 102 were interviewed and 37 deaths were recorded. The chance of vulnerable older people at moment 1 being dependent on performing BADL at moment 2 was 4.19-fold the chance of robust older people. For IADL, the chance of vulnerable older people at moment 1 being dependent at moment 2 was 3.12-fold the chance of robust older people. Cox’s analysis showed that the risk of death among vulnerable older people was 2.50-fold that among robust older people. The results reinforce the importance of monitoring and early intervention to prevent frailty.
