We will assess correlation in the classification of PBDE exposure between the home exposure assessment, levels in breast milk, and levels in house dust. We also will identify factors in the home and diet that predict maternal PBDE levels in breast milk. We will estimate the change in cognitive and behavioral developmental scores relative to total PBDE level and PBDE composition using random effects models and generalized estimating equations, accounting for the correlation in development over time and adjusting for important confounding factors. This study will efficiently estimate contemporary PBDE levels from the largest human sample to date in North America, correlate household sources of exposure with levels measured in dust and in humans, and provide the first results of an investigation of the effects of PBDEs on early human development. These data will provide information about potential risks to development associated with exposure to PBDEs.
Data collection for the study has been administered in the field at four subsequent time points, 3 months, 12 months, 24 months, and 36 months postpartum. Breast milk specimens have been analyzed by the CDC laboratory (n = 389). Analysis of first- and third-year postpartum household dust specimens is planned by the CDC laboratory. Data collection was completed in December 2008, with the completion of 206 environmental questionnaires and 341 developmental assessments at age 36 months. These environmental data have been merged with existing data from the PIN pregnancy and PIN postpartum studies. Analyses and manuscript preparation are underway.
Data analysis and preparation of presentations and publications during 2009 and 2010.
