This study aimed to examine whether olfactory impairment is associated with an accelerated decline in muscle strength among older adults.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We analyzed data from 2348 participants (aged 71-82\u2009years; 48.0% men; 37.5% Black) in the Health, Aging, and Body Composition Study. Olfactory function was assessed using the Brief Smell Identification Test at the Year 3 clinical visit (1999-2000) and categorized as good (scores 11-12), moderate (9-10), hyposmia (7-8), or anosmia (0-6). Participants were followed for up to 7\u2009years. Grip strength and quadriceps strength were measured at clinical visits in Years 4, 6, 8, and 10.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>During follow-up, participants with anosmia experienced a faster decline in grip strength than those with good olfaction. The annual difference in decline was \u22120.19\u2009kg\/year (95% confidence interval [CI], \u22120.37 to \u22120.01) for men and \u22120.21\u2009kg\/year (95% CI, \u22120.37 to \u22120.05) for women. For quadriceps strength, men with anosmia had a greater annual decline (\u22121.26\u2009Nm\/year; 95% CI, \u22122.26 to \u22120.26), whereas no statistically significant association was observed in women.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Anosmia in older adults is associated with accelerated decline in muscle strength.
