Walking and psychomotor speed in the elderly: concordance, correlates and prediction of death.

摘要: To investigate the concordance between walking (WS) and psychomotor speed (PS), correlates of both tasks, their capacity to predict mortality in elderly. Seven-year cohort study 1,365 community-dwelling subjects aged 65-95 years, participating Bordeaux sample Three City Study, a French prospective designed evaluate risk cognitive decline attributable vascular factors. Participants completed battery assessments including time complete Trail Making Test A used as PS measure, measure WS. Socio-demographic determinants, co-morbidities, functional evaluation, incident were taken into account. Mean age was 75.7 (SD ± 5.4) years. WS TMT-A have very low (kappa coefficient=.05). The each different: mostly clinical co-morbidities for WS, cognition function speed. However, are independent predictors death after seven years follow-up. could be considered two different dimensions age-related slowness, but performances associated with higher mortality.
