Objective:
In this project we will develop and apply statistical methods to national data sources to: 1) carry out multi-site time series studies for estimating short-term effects of PM and PM components on mortality and morbidity (Phase I); 2) carry out cohort-studies for estimating long-term effects of PM and PM components in susceptible populations (Phase II); and 3) assess coherence of evidence from bioassays and epidemiological studies on PM toxicity and susceptibility, and explore linkages of sources of harmful PM components to human health risks (Phase III).
By providing individual-level health data for the entire U.S. population of elderly, the National Medicare Cohort will allow us to take full advantage of all existing and future air quality databases on PM and its characteristics. This project will address the following objectives of the Center on a national scale: 1) mapping risks of PM and PM constituents to human health across the United States; 2) using the maps to identify a sampling frame of locations with contrasting higher and lower risks; and 3) carrying out more refined epidemiological studies to estimate further the risks of the more toxic particles to susceptible individuals.
Progress Summary:
The progress of Project 1, entitled “Estimation of the Risk to Human Health of PM and PM components,” is summarized below.
Phase I: Multi-Site Time Series Studies for Estimating Short-Term Effects of PM and PM Components on Mortality and Hospitalization
Progress toward Phase I includes:
- Updating Medicare billing claims, weather, and air pollution data sources to the year 2005.
- Characterizing spatial and temporal variability of PM2.5 and PM2.5 components across the United States. The manuscript entitled: Spatial and Temporal Variation in PM2.5 Chemical Composition in the United States for Health Effects Studies (2000-2005) led by Dr. Bell is close to submission.
- Applying statistical methods for multi-site time series studies for estimating short-term effects of PM2.5 on hospitalization from the National Medicare Cohort. The manuscript entitled Particles Air Pollution Fine Particulates Air Pollution and Hospital Admission for Cardiovascular and Respiratory Diseases, led by Dr. Dominici has been published in the Journal of the American Medical Association, March 8, 295:1127-1135.
- Developing statistical methods for multi-site time series studies to investigate whether short-term effects of PM10 (and PM2.5) on mortality are decreasing over time. The manuscript entitled An Update on the NMMAPS Associations Between Particulate Matter and Mortality (1987-2000): Toward a Methodology for Accountability, led by Dr. Dominici has been submitted to Epidemiology.
- Developing several methodologies for estimating short-term effects of PM2.5 chemical components.
Phase II: Cohort Studies Based on the National Medicare Cohort for Estimating Longer-Term Effects of PM and PM Composition in Susceptible Populations and for Cause-Specific Health Outcomes
Progress toward Phase II includes:
- Developing statistical methods for cohort studies for estimating whether long-term trends in PM2.5 levels are associated with long-term trends in mortality rates. The manuscript entitled: Trends in Particulate Matter and Mortality in 113 U.S. Counties, 2000-2002: Evidence on the Long Term Effects of Air Pollution, led by Dr. Janes has been submitted to Epidemiology.
- Carrying out cohort studies for estimating the long-term effects of PM2.5 on mortality, adjusted by spatial confounding. The manuscript entitled Mortality in the Medicare Population and Chronic Exposure to Fine Particulate Air Pollution led by Dr. Zeger is in the process of being submitted.
- Carrying out re-analyses of the American Cancer Society Study and of the Six Cities Harvard study by using the Medicare data. The manuscript entitled Re-analysis of the American Cancer Society Study by use of Medicare data (2000-2002) is in process of being submitted.
Future Activities:
Over the next six months, the first phase of analyses will be completed so that Project 2 can move forward with its sampling activities. In particular, maps of risks associated with PM will be developed for the United States and further overlaid with geographic variation in characteristics of PM2.5. We will then move forward with analyses directed at risks associated with PM2.5 components.
