Abstract
AIM: Slow gait speed has been associated with mortality, poor physical function and disability in older people. Our aim was to evaluate the association between slow gait speed and rapid cognitive decline among oldest-old men in Taiwan. METHODS: We carried out a longitudinal cohort study in a veterans' retirement community, and enrolled 249 male residents aged 80 years and older. Slow gait speed was defined as <1 m/s, and rapid cognitive decline was defined as a Mini-Mental State Examination (MMSE) decline of ≥3 points over 1 year. Body mass index, Charlson's Comorbidity Index, handgrip strength, gait speed and Mini-Mental State Examination datasets were collected, and a logistic regression model was built to evaluate the association between fast cognitive decline and slow gait speed. RESULTS: In all, 249 residents (mean age 86.4 ± 4.01 years) were recruited, including 58 (23.3%) with rapid cognitive decline. Univariate analysis showed that slow gait speed could predict rapid cognitive decline (OR 4.10, 95% CI 1.20-14.00, P = 0.024). After adjusting for age, Charlson's Comorbidity Index, polypharmacy, psychiatric drug usage, cigarette smoking experience, baseline cognitive function, depressive mood, handgrip strength, nutritional status and history of fall, slow gait speed was still independently associated with rapid cognitive decline (adjusted OR 4.58, 95% CI 1.22-17.2, P = 0.024). CONCLUSIONS: Slow gait speed was thus an independent predictor of rapid cognitive decline in oldest-old men in a veterans' retirement community in Taiwan.
