Resumo

Os objetivos deste estudo foram: (1) investigar as diferenças associadas à idade na função cognitiva (FC), status nutricional (MNA), atividade física (AF), qualidade de vida (QV), depressão, satisfação social (SS) e estatuto socioeconômico (ESSE), e (2) explorar as relações entre a FC e as varáveis anteriores. Este estudo, de natureza transversal, incluiu 268 homens e 433 mulheres (71,4 ± 7,0 anos de idade). A FC foi determinada a partir do Cognitive Telephone Screening Instrument (COGTEL) e do Mini-Mental State Examination (MMSE). Os preditores analisados incluíram: o Mini Nutritional Assessment (MNA), a AF (questionário de Baecke modicado para idosos), a QV (SF-12), a Escala de Depressão em Geriatria (GDS), a Escala de Satisfação com o Suporte Social e o ESSE (Estatuto Socioeconômico). Todos os instrumentos foram aplicados sob forma de entrevista. Um t-teste de medidas independentes identificou scores significativamente mais elevados nos adultos-idosos mais jovens (60 - 69 anos de idade) na FC (p < 0,001), AF (p = 0,046) e ESSE (p = 0,007), comparativamente aos mais idosos (70 - 91 anos de idade). Os resultados da análise de regressão linear múltipla indicaram que os preditores mais significativos da FC foram: ESSE (β = 0,45; p < 0,001), idade (β = -0,12; p < 0,001), SS (β = 0,12; p = 0,001), GDS (β = -0,11; p = 0,003) e QV (β = 0,08; p = 0,017). O modelo de regressão testado, explicou 36% da variância total do COGTEL. As pessoas mais idosas e deprimidas obtiveram scores mais baixos na FC. Este estudo sugere que entre os preditores estudados, o ESSE é a variável mais forte na explicação da FC nos adultos idosos.
