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.
