Objective:

The main objective of this research project is to investigate associations of selected inflammatory and blood clotting parameters in free living humans with particle and criteria gas exposures.

Progress Summary:

This project is in collaboration with the Boston Veterans Hospital who currently is conducting the Normative Aging Study (NAS). During the first 3 years the VA Hospital has been collecting data. Measurements of approximately 650 individuals out of 1,200 participants have been completed. Statistical analysis, relationships to ambient pollution levels, and geographical relationships have just commenced. A plan for the data analysis was presented during the 2003 Scientific Advisory Committee meeting last March.

A new panel study was conducted last year in St. Louis, MO. Forty-four elderly individuals from four senior independent living facilities were enrolled for participation in the study. To evaluate the effect of traffic-related air pollution on cardiovascular health, individuals participated in a series of four separate day-trips from their suburban residences to activities in downtown St. Louis. Each day trip included two one-hour bus rides on a shuttle bus. In order to characterize gaseous and particulate exposures before, during, and after the bus trips, a number of continuous samplers were employed. These samplers were installed on two roll-around carts and in the rear of the shuttle bus. Continuous measurements of cardiac function were also collected during each day of participation using Holter monitors. In addition, samples of exhaled nitric oxide, blood pressure, blood oxygen, and blood samples were collected from participants before and after the trips. All data have been processed and data analysis has just begun.
