Relative Risk Ratio on the Frailty Prevalence among Korean Elderly Individuals

Abstract

This study discriminated frailty prevalence in the Korean elderly and the Risk Ratio (RR) using the Tilburg Frailty Indicator (TFI), the Comprehensive Geriatric Assessment (CGA) and Frail Index, the Frailty Index (FI), and the Cardiovascular Health Study (CHS). 10,451 and 10,299 respondents aged 65 years were selected from the National Survey on the Actual Conditions of Older Person in Korea from the data collected in 2014 and 2017, respectively. Frailty frequency in 2017 was TFI: 1,268 (16.4%), CGA & FI: 378 (4.9%), FI: 1,691 (21.9%), and CHS: 1,503 (29.2%) and in 2014 was TFI: 1,644 (21.2%), CGA & FI: 93 (1.2%), FI: 2,242 (29%), and CHS: 2,178 (36.3). RR Confidence Interval (CI) between 2014 and 2017 showed in TFI, CGA & FI, FI, and CHS were found .85, 1.64, .82, and .84, however, in CGA & FI showed about 1.64 times higher in determining frailty prevalence risk (p<.001).For assessing frailty in the Korean elderly, CGA & FI is a homogeneous measurement scale while the TFI, CGA & FI, FRAIL Scale, and CHS are heterogeneous scales.
