Objective:

 This project is taking advantage of a rich and unique existing time-series to evaluate novel questions regarding the relationship between air pollution and hospital admissions in Denver, Colorado. We are leveraging five years of data from the Denver Aerosol Sources and Health (DASH) study, including daily fine particulate matter mass (PM­2.5; particulate matter less than 2.5 microns in diameter), species, and source factors, to examine the association of air pollution with novel health outcomes (Objective 1). Additionally, we will explore several questions aimed at providing insight regarding susceptible populations (Objective 2) as well as regarding other potential factors leading to heterogeneity of health effect estimates in relation to ambient air pollution (Objectives 3 and 4).

Progress Summary:

 This summary represents progress during the third year of the research award (April 1, 2013 – March 31, 2014). Colorado State University IRB approval was renewed in August 2013.  We have finished all analyses for Objectives 1-4 of the project (with hospital admission data). We have drafted preliminary manuscripts for these results. The PI of the project participated in the EPA STAR progress review meeting in November 2013.

Future Activities:

The IRB approval for the project will be renewed in August 2014. Manuscripts will be submitted for publication. We will submit a final report to EPA in November 2014.
