Optimizing Air Pollution Exposure Assessment with Application to Cognitive Function

This report, available for downloading below, presents a study led by Lianne Sheppard at the University of Washington. Sheppard and colleagues sought to understand the importance and influence of various study design features on estimating long-term exposure in Seattle, Washington, using these different approaches. For example, they applied their new methods to evaluate the influence of the number, representativeness, and type of air pollution measurements on exposure predictions and health estimates in an existing cohort of older adults. They also developed practical guidance for future mobile monitoring campaigns, addressing a clear research gap.
