Key Points Question Is a frailty index measure at 66 years of age associated with incident age-related chronic disease, disability, and death? Findings This nationwide cohort study of 968 885 Korean individuals found that a frailty index measured at 66 years of age was associated with greater rates of death, new major age-related diseases, and disability-qualifying long-term care services over 10 years. Frailty was associated with faster acquisition of new age-related conditions. Meaning These findings suggest that measuring frailty at 66 years of age provides an aging trajectory that one is likely to follow, which may be useful to mitigate health decline associated with aging.
