Olfaction and Physical Functioning in Older Adults: A Longitudinal Study.

ABSTRACT:

Background

Poor olfaction is associated with worse functional performance in older adults, but longitudinal evidence is lacking. We investigated poor olfaction in relation to longitudinal changes in physical functioning among community-dwelling older adults.

Method

The analysis included 2 319 participants from the Health, Aging and Body Composition study (aged 71-82 years, 47.9% men, and 37.3% Blacks) who completed the Brief Smell Identification Test in 1999-2000. Olfaction was defined as good (test score 11-12), moderate (9-10), or poor (0-8). Physical functioning was assessed up to 4 times over 8 years, using the Short Physical Performance Battery (SPPB) and the Health Aging and Body Composition Physical Performance Battery (HABCPPB). We conducted joint model analyses and
