RESUMO

A cross-sectional analysis was conducted using data from a prospective cohort study to investigate whether frailty is associated with pain intensity, disability caused by low back pain (LBP), and quality of life in an older population with acute non-specific LBP. Six hundred and two individuals with a mean age of 67.6 (standard deviation [SD] 7.0) years were included in the analysis. In relation to frailty status, 21.3 per cent of the sample were classified as robust, 59.2 per cent were classified as pre-frail, and 19.5 per cent were classified as frail. In the unadjusted analysis, pre-frail and frail groups showed significantly higher pain and disability scores than the robust group. Moreover, the same two groups exhibited lower scores in both physical and mental domains of quality of life than the robust group. After adjusting for socio-demographic and clinical variables, disability scores and the physical component of quality of life were significantly associated with frailty. In older adults with acute LBP, frailty is associated with more disability and worse scores in the physical component of quality of life.

RESUMO

OBJETIVOS: Investigar a prevalência do medo de cair em uma população de idosos da comunidade e sua correlação com mobilidade, equilíbrio dinâmico, risco e histórico de quedas. MÉTODOS: Estudo transversal randomizado. Participaram do estudo 147 idosos com idades entre 60 e 92 anos, sendo 94 (65,95 por cento) mulheres e 53 (36,05 por cento) homens. O medo de cair foi avaliado usando FES-I-BRASIL (FIB), a mobilidade foi avaliada por meio do teste "Timed Up and go" (TUG), o risco de quedas, por meio do "Functional Reach Test" (FRT) e o equilíbrio dinâmico, pelo teste da Marcha Tandem (MT). RESULTADOS: Cento e trinta e três (90,48 por cento) idosos relataram medo de cair em pelo menos uma atividade, e 80 (54,42 por cento) dos idosos apresentaram histórico de quedas (HQ). A correlação de Pearson demonstrou resultado significante (p<0,001) do medo de cair com MT (r=-0,44248), FRT (r=-0,51562), HQ (r=0,54069), TUG (r=0,45738) e idade (r=0,39772). CONCLUSÕES: O presente estudo identificou alta prevalência de medo de cair nos idosos da comunidade, independente do HQ, e correlação significativa do medo de cair com mobilidade, equilíbrio dinâmico, risco e HQ.

OBJECTIVES: To investigate the prevalence of fear of falling among a population of older adults and its correlation with mobility, dynamic balance, risk and history of falls. METHODS: This was a randomized cross-sectional study. The participants were 147 older adults between the ages of 60 and 92: 94 women (65.95 percent) and 53 men (36.05 percent). Fear of falling was assessed using FES-I-BRAZIL (FIB); mobility, using the "timed up and go" (TUG) test; risk of falls, using the "functional reach test" (FRT); and dynamic balance, using the "tandem gait test"(TGT). RESULTS: One hundred and thirty-three older adults (90.48 percent) reported fear of falling in at least one activity and 80 older adults (54.42 percent) had a history of falls (HF). Pearson's correlation was statistically significant (p<0.001) between fear of falling and the TGT (r=-0.44248), FRT (r=-0.51562), HF (r=0.54069), TUG (r=0.45738) and age (r=0.39772). CONCLUSIONS: The present study identified high prevalence of fear of falling among older adults in the community, independent of their history of falls, and significant correlations between fear of falling and mobility, dynamic balance, risk and history of falls.
