Comparação do risco de queda em idosos sedentários e ativos por meio da escala de equílibrio de Berg / Comparison of fall risk between sedentary and active aged by means of the Berg balance scale

RESUMO

O envelhecimento da população é um fenômeno mundial, do qual o Brasil apresenta um dos mais agudos processos. A prática regular de exercícios por idosos pode melhorar a capacidade física, proporcionar ganho de auto-estima e confiança, contribuindo para diminuição do risco de quedas, comuns em idosos. Este estudo visou comparar o risco de quedas entre idosos sedentários e ativos, verificando como a prática de exercício físico se reflete no desempenho dos sujeitos na escala de Berg. Foram avaliados por esse instrumento 70 idosos, divididos em 2 grupos: sedentários (n=35) e ativos (n=35)...

ABSTRACT

Population aging is a worldwide phenomenon which is particularly acute in Brazil. Regular physical exercise by the aged may improve physical capacity, provide gains in self-esteem and confidence, and contribute to reducing the number of falls, which are common among the elderly. This study aimed at comparing fall risk between sedentary and active elderly subjects, by assessing how the regular practice of physical exercises is reflected by subjects’ performance at the Berg balance scale. Seventy elderly subjects were divided into 2 groups, sedentary (n=35) and active (n=35), and submitted to the Berg test. The sedentary group mean score at the Berg scale was 47.7±5.6, and the active groups’, 53.6±3.7 (p<0.0001). The odds ratio analysis showed that fall risk was 15.6 times higher for the sedentary group as compared to the active group (p=0.002). Since the performance of the sedentary group at the Berg scale was worse than the active group’s, it may be said that regular practice of physical activities affects such performance, and that physically active subjects present less fall risk than sedentary ones...
