Actividades diarias evaluadas mediante monitor de actividad de alta precisión en adultos mayores: resultados preliminares del Estudio IMPACT65+

Abstract

IntroductionPhysical activity and physical inactivity patterns can affect health status. In the elderly people, their study is relevant given the importance that they have on the morbidity and mortality. ObjectiveTo present preliminary data on activity and inactivity patterns of a sub-sample of older adults from the IMPACT65+ Study. Material and methodsThe sample included the first 84 participants (57% women) over 65 years (age 70.7±4.7). Time spent in activity and inactivity patterns was obtained from an Intelligent Device for Energy Expenditure and Activity monitor over a continuous period of 24hours. The patterns analysed were: standing, lying down, sitting or reclining, and the transition between them. The physical activity patterns analysed were; walking, step up or step down, running, and jumping. ResultsTime spent in inactivity patterns like reclining, lying down, and sitting was 16.1±1.9hours (67% day), while the amount of time spent in activity patterns was 2.4±1.9hours (10% day). Differences were observed between men and women in the amount of hours sitting (9.7±3 men vs. 7.5±2.7 women) and standing (4.5±1.4 men vs. 5.6±2.7 women). These differences were greater in the older participants. ConclusionsPreliminary results show that older adults spend a great part of day in inactivity patterns like sitting, and that gender is the only factor analysed that affects the time spent in the activity patterns analysed.
