Frailty Index Predicts Future All-cause Mortality and Quality of Life: A 2-Year Follow-up Study Among Korean Older Adults From a Population-based Cohort Study.

ABSTRACT:

Objectives

The frailty index (FI), a proxy measure of accelerated biological aging, predicts adverse outcomes in older adults. We investigated whether the FI predicts mortality in a community-based Korean older adult population and its association with subjective health status over 2 years.

Methods

This prospective cohort study included 936 community-dwelling individuals aged ≥60 years. The FI, calculated from 28 self-reported baseline variables, was scored on a scale from 0 to 1 (<0.25: non-frail; 0.25-0.34: mildly frail; ≥0.35: moderately to severely frail). The primary outcome was 2-year all-cause mortality. Relative risks (RRs) and 95% confidence intervals (CIs) were calculated. Quality of life was assessed using the European Quality of Life Five-Dimension Three-Level
