Ambient Air Pollutants and Olfaction among Women 50-79 Years of Age from the Sister Study.

ABSTRACT:

Background

Poor olfaction is common in older adults and may have profound adverse implications on their health. However, little is known about the potential environmental contributors to poor olfaction.

Objective

We investigated ambient fine particulate matter [PM ≤2.5μm in aerodynamic diameter (PM2.5)] and nitrogen dioxide (NO2) in relation to poor olfaction in middle-aged to older women.

Methods

The Sister Study is a nationwide cohort of 50,884 women in the United States with annual average air pollutant exposures estimated based on participants' residences from enrollment (2003-2009) through 2017. This analysis was limited to 3,345 women, 50-79 years of age as of January 2018, who completed the Brief Smell Identification Test (B-SIT) in 2018-2019. Poor olfaction wa
