ABSTRACT
The aim of this study was to identify the amount of time spent in sedentary behavior that may be critically related to functional disability in older adults. A cross-sectional study was conducted with a random sample of 624 older adults (65.1% women) aged 60 to 96 years. Perceived limitations in instrumental activities of daily living were used as indication of functional disability. Time spent in sedentary behavior was assessed using the International Physical Activity Questionnaire (IPAQ). The prevalence of functional disability was 29.4%. The mean total time spent in sedentary behavior was 576.51 ± 5.14 min/day. Receiver Operating Characteristic (ROC) curves were used to identify cut-points for time spent in sedentary behavior that could discriminate functional disability in older adults. The results suggested that spending > 600.00 min/day and > 614.00 min/day in sedentary behavior, for men and women, respectively, was a discriminator for functional disability in the current study. These cut-points can be used to identify older adults who are most vulnerable to functional disability in future studies
RESUMO
O objetivo deste estudo foi identificar pontos de corte para o tempo gasto em comportamento sedentário que podem potencialmente discriminar a presença de incapacidade funcional em idosos. Um estudo transversal foi realizado com uma amostra aleatória de 624 idosos (65,1% mulheres) com idade entre 60 e 96 anos. As limitações percebidas nas atividades instrumentais da vida diária foram utilizadas como indicação de incapacidade funcional. O tempo gasto no comportamento sedentário foi avaliado usando o Questionário Internacional de Atividade Física (IPAQ). A prevalência de incapacidade funcional foi de 29,4%. A média do tempo total despendido em comportamento sedentário foi de 576,51 ± 5,14 minutos/dia. As curvas de ca-racterística operativa do receptor (ROC) foram usadas para identificar pontos de corte para o tempo gasto em comportamento sedentário que discriminassem a incapacidade funcional em idosos. Os resultados sugeriram que despender > 600,00 min/dia e > 614,00 min/dia em comportamento sedentário, para homens e mulheres, respectivamente, foram discriminadores de incapacidade funcional no presente estudo. Esses pontos de corte podem ser usados para identificar os idosos que estão em maior vulnerabilidade à incapacidade funcional em estudos futuros
