Frailty state transitions among non-frail and vulnerable older adults: Does mobility performance really matter?

We assessed the predictors of becoming frail between non-frail and vulnerable community-dwelling older adults in a retrospective cohort study with adults (n=346) aged 60 years or older recruited from primary healthcare centers. Edmonton Frailty Scale assessed frailty status, and Kaplan-Meier estimated the frailty-free probability and compared it between groups. Cox regression models explored predictors of becoming frail. At baseline, there were 32.3% individuals classified as Frail according to the EFS, whereas 32.4% were vulnerable and 35.3% non-frail. We observed 82 incident cases of frailty, 65.8% among those classified as vulnerable and 37.8% in the non-frail group (p < 0.05). Female sex, years of education, and an overall score of < 45 on the Berg Balance Scale were the only independent predictors of becoming frail. Although frailty is not only correlated with mobility, static and dynamic balancing abilities appear to have the same impact as a vulnerable state to becoming frail.
