Association between long-term healthy aging trajectories and all-cause mortality among middle-aged and older adults.

ABSTRACT:

Background

Healthy aging is associated with lower mortality and better quality of life. This observational study examines how different healthy aging trajectories relate to all-cause mortality in middle-aged and older adults and seeks to identify subgroups at elevated risk based on individual characteristics.

Methods

We used data from the Korean Longitudinal Study of Aging (KLoSA) collected between 2006 and 2020. The analytic sample comprised 4,168 adults aged 45 years and older. Healthy aging trajectories were derived from 2006 to 2014 using group-based trajectory modeling (GBTM) applied to a composite score (range 0-5) constructed from five binary domains: presence of chronic disease(s), limitations in activities of daily living (ADL), depressive symptoms, cognitive impair
