Description:
Objective:This project focuses on statistical investigations into the relationship between air quality and respiratory health in the Chicago area. The specific objectives of this research project are to: (1) identify atmospheric states most likely to be accompanied by elevated ground-level ozone amounts in Illinois; (2) elaborate on and develop statistical models to describe the spatio-temporal structure in ground-level ozone; (3) examine and compare different measures of asthma incidence for use in population-based studies of the effects of air pollution on respiratory health; and (4) develop statistical models to link acute asthma occurrence in Chicago’s Medicaid population to levels of ozone, particulate matter, pollen, and meteorological conditions in both urban-aggregated and spatially resolved ways.
Research results to date are summarized below for each objective. Problems encountered are mostly centered on the spatial, and in some cases the temporal, coverage of specific data sets related to atmospheric conditions, air quality, and health outcomes. The health outcome data are organized spatially at the level of ZIP code. On any given day, ozone is measured hourly at a minimum of 11 sites in Cook County, but this still does not provide sufficiently dense coverage for all of Cook County’s 56 ZIP codes. Pollen is a significant factor in asthma occurrence, but the available data include only one daily value for the entire Chicago area. The data set for large particles, particulate matter (PM10), has sparse spatial coverage and contains information at irregular time intervals, where the period between data points at a specific site can be up to 6 days. Data on PM2.5 are not available for the same time frame for much of our health outcome data.
Therefore, we are faced with significant problems of incompatible space-time scales across the multiple data sources to be used in our research project. In response to the issues posed by such problems of scale, we are investigating a variety of statistical spatio-temporal modeling techniques, the use of independent data sets with higher spatial resolutions, and physical models (MM5, Community Multiscale Air Quality [CMAQ]) for use in generating spatio-temporal structure in localized factors that may influence asthma incidence. The problems identified are significant, and they have served as a part of the wider impetus for developing important new statistical methodology that will be applicable in our study and in other studies with similar study designs. Consistent with the evaluation provided by the external Advisory Board, upcoming work in this research project will make extensive use of new spatio-temporal statistical methods (developed in another Center for Integrating Statistical and Environmental Science [CISES]-supported effort), as well as the capability in physical modeling of meteorology and air quality at high spatial resolutions. In addition, the longer-term objective of developing improved statistical models for linking acute asthma events to air quality indicators is a driving force behind most of our efforts, and work will continue on these models for the duration of the research project. The effort devoted to identifying relationships between meteorological regimes and air quality has been completed (Eshel and Bernstein, 2003), and further work in this area will not be undertaken.
