In this Project we investigate the acute and chronic effects of air pollution on cognitive and neurological impairments, systemic inflammation, and vascular dysfunction. We will determine how these effects differ depending on the composition of multi-pollutant mixtures and the source contributions to PM composition. We then will ascertain the level of increased effects in susceptible and vulnerable subpopulations by examining modifying factors of obesity, diabetes, diet, socioeconomic position, and psychosocial stress.
While the project has only recently begun, we have the following accomplishments to report:
- A key part of this project and of all the cohort studies is development of a spatio-temporal model predicting daily PM2.5 concentrations in New England using land use regression terms and satellite remote sensing. We have developed that model, and have a paper in review describing it. We have papers in progress using it to examine the association of PM2.5 with birthweight and mortality. A poster on this work will be presented at the International Society for Environmental Epidemiology meeting in Barcelona in September.
- We have published a paper examining the association of long-term exposure to black carbon particles at residence and cognitive function in the Normative Aging Study. This paper shows that traffic particles are associated with lower cognitive function, similar to a few years of aging, in an elderly cohort (Power et al., 2011, see publications).
- We have a paper in press (Peters, et al., 2011, see publications) reporting an association between long-term lead exposure and psychosocial stress. This will serve as a template for further examination of other air pollutants.
- We have a paper in press using our novel approach to within city survival analysis to examine the association of ozone in survival in four cohorts of potentially susceptible individuals. We find significant associations with long-term survival, only the second paper to report such results (Zanobetti and Schwartz, 2011, see publications).
- We will present preliminary results of an analysis of long-term exposure to black carbon and Intima-media thickness of the carotid artery at the ISEE meeting in September.
- We also will present results of a genome wide DNA methylation analysis to identify genes whose methylation is significantly perturbed by air pollution at the ISEE meeting in September.
- We will present results of a further follow up of the Harvard Six Cities study at the ISEE meeting in September that examines more years of follow up, and addresses the linearity of the dose-response curve and sensitivity to modeling assumptions.
We will continue to work on the activities proposed in our grant application. In addition, we expect to receive a grant from NIEHS to look at epigenomic effects of environmental exposures that will allow us to continue to examine exposure and epigenetic effects in the Normative Aging Study. We expect the ISEE presentations to become published papers in the next year.
