Prevalence and Correlates of Olfactory Dysfunction in Old Age: A Population-Based Study.

ABSTRACT:

Background

Olfactory dysfunction (OD) in old age is associated with poor health outcomes. Interrelationships among different correlates of OD can offer insights into the underlying mechanisms, but to date remain understudied.

Methods

Odor identification performance and self-reported olfactory functioning were studied in 2,234 people aged 60-90 years, who were free of neurodegenerative disease and enrolled in the Swedish National Study on Aging and Care in Kungsholmen (SNAC-K) study, Stockholm, Sweden.
