Longitudinal Association of Olfactory Function with Frailty in Older Adults: The Atherosclerosis Risk in Communities Study.

ABSTRACT:

Background

Emerging evidence suggests that olfactory dysfunction may be a marker of frailty, a key predictor of adverse health outcomes in aging populations. This study examines the association between olfactory impairment and frailty in older adults.

Methods

We analyzed data from 5,231 participants (mean age: 75.3 ± 5.0 years; 59% women; 22% Black) of the Atherosclerosis Risk in Communities (ARIC) Study. Olfactory function, assessed using the 12-item Sniffin' Sticks Test at Visit 5 (2011-2013), was categorized as poor (0-8), moderate (9-10), or good (11-12). Frailty status was ascertained using both the Fried Frailty Phenotype and the Cumulative Frailty Index. Cross-sectional associations between olfactory function and frailty status were examined using logistic regression
