Usual gait speed is associated with frailty status, institutionalization, and mortality in community-dwelling rural older adults: a longitudinal analysis of the Aging Study of Pyeongchang Rural Area
PURPOSE: We aimed to describe the age- and sex-specific distributions of gait speed and to evaluate associations with longitudinal outcomes in Korean rural community-dwelling older adults. PATIENTS AND METHODS: A total of 1,348 people (mean age: 76 years, 55% women) in the population-based, prospect...

description | PURPOSE: We aimed to describe the age- and sex-specific distributions of gait speed and to evaluate associations with longitudinal outcomes in Korean rural community-dwelling older adults. PATIENTS AND METHODS: A total of 1,348 people (mean age: 76 years, 55% women) in the population-based, prospective cohort of Aging Study of Pyeongchang Rural Area (ASPRA) between October 2014 and June 2017. All participants underwent a comprehensive geriatric assessment, including 4-m usual gait speed, and were followed annually. RESULTS: Among the 1,348 participants, women had a slower gait speed than men (mean 0.709 m/s vs 0.850 m/s, P < 0.001). Gait speed was inversely associated with age, frailty index; slow gait speed as classified by sex-specific quartile was associated with the prevalence of common geriatric syndromes. During the mean follow-up period of 21.5 months (SD 7.88), future survival without mortality or institutionalization was affected by sex-specific gait-speed quartile (log rank test P < 0.001): the 1st quartile of sex-specific gait speed was associated with increased risk of death or institutionalization. CONCLUSION: Gait speed was related to age, sex, frailty status, and geriatric health outcomes in Korean rural community-dwelling older adults. Since this gait-speed distribution in an older Korean population differs from previous data on other populations, we should consider a gait-speed cutoff value based on sex-specific quartiles to prevent misclassification in sarcopenia and frailty diagnosis. |
