Combining Gait Speed and Recall Memory to Predict Survival in Late Life: Population‐Based Study

摘要: Objectives To evaluate the relationship between gait speed, recall memory, and mortality. Design A cohort study (last follow-up December 2009). Setting Tuscany, Italy. Participants Individual data from 1,014 community-dwelling older adults aged 60 years or with baseline speed memory measurements for a median time of 9.10 (IQR 7.1;9.3) years. Participants were mean (SD) age 73.9 (7.3) years, 55.8% women. walking faster than 0.8 m/s defined as fast walkers; good was score 2 3 in 3-word delayed section Mini-Mental State Examination. Measurements All-cause mortality. Results There 302 deaths overall 100 person-year death rate 3.77 (95% CI: 3.37–4.22). Both low poor associated mortality when analysed separately (HR = 2.47; 95% 1.87–3.27 HR 1.47; 1.16–1.87, respectively). When we grouped participants according to both rates (100 person-years) progressively increased those (2.0; 1.6–2.5), walk but (3.4; 2.8–4.2), slow (8.8; 6.4–12.1), (13.0; 10.6–16.1). In multivariate analysis, significantly increases risk among persons 1.40; 1.04–1.89). Conclusion In persons, are independent predictors expected survival. Information on function might better stratify speed.
