Abstract #73790

Using a Geographic Information System to Study Statewide Patterns of Childhood Cancer Incidence in California

Peggy Reynolds, PhD, Environmental Health Investigations Branch, California Department of Health Services, 1515 Clay Street, Suite 1700, Oakland, CA 94612, 510-622-4417,

There is a long history of community concerns that environmental factors might contribute to apparent “clusters” of rare health outcomes such as childhood cancer. Inevitably there are too few events on a community by community basis to provide sufficient study power to detect risk associations of interest, if they exist. Furthermore, environmental exposures are difficult to estimate in more traditional epidemiologic study designs, which rely on respondent self-report for factors which may be unknown to the individual. With the advent of new geographic information system (GIS) tools, the California Department of Health Services has been able to undertake a series of studies broader in scale, integrating several independent sources of information, in order to evaluate the patterns of cancer with respect to environmental risk factors of interest. Examples of this approach will be given for a statewide study of childhood cancers, which uses two complementary study designs and GIS tools to estimate exposure potential to several environmental toxics that have been of public interest, particularly to agricultural pesticides and mobile source emissions.
