Abstract
Existem diferenças metodológicas na literatura acerca da medida de atividade física referente à fragilidade. Assim, o objetivo do presente estudo foi investigar relações entre fragilidade e medidas de atividade física. O estudo teve uma amostra probabilística de 689 idosos (72,28 ± 5,40 anos; 68,21% mulheres). Foi utilizada versão adaptada do Minnesota Leisure Time Physical Activity Questionnaire e estabelecidos dois critérios para as medidas de atividade física: prática regular de exercícios físicos e taxa semanal de gasto calórico em exercícios físicos e em atividades domésticas. Quanto à pontuação, 15,09% dos idosos pontuaram em perda de peso; 17,13%, em fadiga; 16,96%, em baixa força de preensão; 15,87%, em lentidão de marcha; 43,02%, em comorbidades. A frequência de ativos pelo critério de gasto calórico foi de 83,55%; por prática de exercícios físicos, 45,27%. Houve associações entre baixo nível de gasto calórico e baixa força de preensão, lentidão de marcha e idade avançada; entre sedentarismo quanto à prática de exercícios físicos e comorbidades. A medida conforme gasto calórico foi mais sensível aos indicadores de fragilidade, e a medida conforme prática de exercícios físicos, ao estado de saúde.
The literature shows methodological differences in measuring physical activity in relation to frailty in the elderly. Therefore, the aim of the present study, part of FIBRA (the Frailty in Brazilian Elderly study), was to investigate relationships between frailty and measurements of physical activity. The study used a probabilistic sample of 689 elderly (72.28 ± 5.40 years; 68.21% women). An adapted version of the Minnesota Leisure Time Physical Activity Questionnaire was used and two criteria were established for measuring physical activity: regular physical exercise and weekly calorie expenditure during physical exercise and household activities. Of the total sample, 15.09% scored on weight loss, 17.13% on fatigue, 16.96% on low grip strength, 15.87% on slow gait, and 43.02% on comorbidities. According to the calorie expenditure criterion, 83.55% of the elders were classified as active, as compared to 45.27% according to the physical activity criterion. Low calorie expenditure was associated with low grip strength, slow gait, and advanced age. Sedentary lifestyle (limited physical activity) was associated with comorbidities. Calorie expenditure was more sensitive for measuring frailty, while physical activity was more sensitive for measuring health status.
