Relationship Between Poor Olfaction and Mortality Among Community-Dwelling Older Adults: A Cohort Study.

ABSTRACT:

Background

Poor olfaction is common among older adults and has been linked to higher mortality. However, most studies have had a relatively short follow-up and have not explored potential explanations.

Objective

To assess poor olfaction in relation to mortality in older adults and to investigate potential explanations.

Design

Community-based prospective cohort study.

Setting

2 U.S. communities.

Participants

2289 adults aged 71 to 82 years at baseline (37.7% black persons and 51.9% women).

Brief Smell Identification Test in 1999 or 2000 (baseline) and all-cause and cause-specific mortality at 3, 5, 10, and 13 years after baseline.
