Overlap of frailty, comorbidity, disability, and poor self-rated health in community-dwelling near-centenarians and centenarians.

Abstract

A cross-sectional data analysis of 121 community-dwelling Chinese near-centenarians and centenarians (mean age 97.7±2.3, range 95 108; 74.2% female) was performed to examine the prevalence of overlap between frailty, comorbidity, disability, and poor SRH. Based on the FRAIL scale, 20% of participants were regarded as nonfrail (score 0), 56% were prefrail (score 1-2), and 24% were frail (score >2). Figure 1 illustrates the prevalence of overlap of frailty, disability, comorbidity, and poor SRH. Every frail participant had at least one comorbidity, one disability, or poor SRH. Frailty cooccurred with poor SRH in 32.4% of participants (24/74), with disability in 31.4% (22/70), and with comorbidity in 26.0% (19/73); 71.0% of participants had poor SRH, disability, or comorbidity or some combination but were not frail. Of all possible combinations, the most common combination was having all four symptoms (frailty, poor SRH, disability, comorbidity; n=17, 14.0%). Eleven (9.1%) participants could be regarded as robust because they did not meet any of the four parameters.
