Abstract:
|
The relation between early childhood development and maternal exposures to environmental chemicals during pregnancy is an important issue when considering the residential exposure risk. In this study we examine a range of modeling methods where we have geo-coded residential addresses for mothers during the different months of pregnancy and mental retardation and development delay (MRDD) outcome measures for the babies for a Medicaid population in South Carolina. We also have available measures of soil chemistry (e.g. total microtox EC50) on a network of sites. Our modeling involves interpolation methods for spatially-referenced measures to locations of residence that vary with time. We also develop a logistic spatial model for the MRDD outcome and clustering in that outcome which can be time-dependent or designed to be a function of the cumulative exposure over all addresses resided in.
