A frailty-intrinsic capacity index to predict disability in community-dwelling older Japanese adults.

ABSTRACT:

Purpose

We constructed and validated a frailty-intrinsic capacity (FR-IC) index for predicting disability in community-dwelling older Japanese adults.

Methods

This longitudinal cohort study included 1179 participants aged ≥60 years (mean age: 71.3 ± 7.4 years, 51 % men). A multidisciplinary geriatric team constructed a 35-item FR-IC index (score range: 0: robust to 1: severe frailty, accumulation model) comprising 15 domains incorporating the intrinsic capacity concept (IC-Vision, IC-Hearing, IC-Locomotor capacity, IC-Cognition, IC-Vitality, and IC-Psychological capacity) based on questionnaires widely used in Japan. To test predictive validity, age- and sex-adjusted Cox proportional hazard models estimated hazard ratios (HRs) for incident disability (care need levels ≥1) by
