Associations of aging trajectories for an index of frailty score with mortality and medical and long-term care costs among older Japanese undergoing health checkups.
Using up to 13 years of repeated-measures data, we identified aging trajectories for an index in frailty score among older Japanese undergoing health checkups. In addition, we examined whether these trajectories were associated with all-cause and cause-specific mortality and healthcare costs. ⋯ Higher aging trajectories in frailty score were associated with elevated risks for cardiovascular, other-cause and all-cause death among older Japanese receiving health checkups. Medical and care needs greatly increased for the second and third trajectory groups when their frailty level was progressed in later life. Geriatr Gerontol Int 2020; 20: 1072-1078..
