Associations between physical and cognitive activities and olfactory function in older adults.

ABSTRACT: Olfactory function plays a vital role in daily life but tends to decline with age, affecting health and wellbeing. While previous studies suggest a link between physical activities and olfactory function in older adults, the relationship between cognitive activity and olfactory function remains unclear, as do the combined effects of both activities. This cross-sectional study examined associations between physical and cognitive activity and three domains of olfaction (identification, sensitivity, and memory) in 583 community-dwelling older adults. Both types of activity were positively associated with overall olfactory performance. Physical activity exhibited the strongest link with olfaction identification, while cognitive activity was more closely related to olfaction memory. Furthermore
