Desempenho físico de membros inferiores, força de preensão manual e qualidade de vida de idosos / Lower limb physical performance, handgrip strength and quality of life of elderly

RESUMO

Este estudo teve o objetivo de verificar a associação entre o desempenho físico de membros inferiores e a força de preensão manual (FPM) com a qualidade de vida (QV) de idosos. Estudo transversal realizado com 608 idosos. Foi utilizado o Short Physical Performance Battery (SPPB); o teste de força de preensão manual, o World Health Organization Quality of Life-Bref (WHOQOL-BREF) e o World Health Organization Quality of Life Olders (WHOQOL-OLD). Realizou-se análise descritiva e regressão linear (p<0,05). Menores escores no SPPB e na FPM associaram-se a pior QV nos domínios físico (p<0,001; p=0,003), psicológico (p<0,001; p=0,001) e meio ambiente (p<0,001; p=0,028) e nas facetas de funcionamento dos sentidos (p=0,001; p<0,001) e atividades passadas, presentes e futuras (p=0,001; p=0,010). Verificou-se que existem domínios e facetas de QV em comum e específicos que se associaram ao desempenho físico de membros inferiores e a FPM.

ABSTRACT

This study aimed to verify the association between physical performance of lower limbs and handgrip strength (HGS) with the quality of life (QOL) of the elderly. Cross-sectional study carried out with 608 elderly people. The following were used: Short Physical Performance Battery (SPPB); handgrip strength test; World Health Organization Quality of Life-Bref (WHOQOL-BREF) and World Health Organization Quality of Life Olders (WHOQOL-OLD). Descriptive analysis and linear regression (p<0.05) were performed. Lower SPPB and HGS scores were associated with worse QOL in the physical (p<0.001; p= 0.003), psychological (p<0.001; p= 0.001) and environment (p<0.001; p= 0.028) domains and in the facets functioning of the senses (p= 0.001; p<0.001) and past, present and future activities (p= 0.001; p= 0.010). It was found that there are common and specific QOL domains and facets associated with physical performance of lower limbs and HGS.
