Research Category: Children's Health
Objective:
The overarching objective of this Center is to make causal linkages between cumulative environmental exposures, caregiving environments in early childhood, and changes in neurodevelopment for preschoolers.
Project 1: The objective of Project 1 is to identify the occurrence, concentration, and variation of chemicals found in toddler’s caregiving environments at home and in child care, and evaluate how the cumulative chemical exposures are causally associated with neurodevelopmental functioning in early childhood.
Project 2: The objective of Project 2 is to test whether nonchemical factors, specifically home caregiving environment, alter the impacts of early life chemical exposures (i.e., metals, polybrominated diphenyl ethers, per- and polyfluoroalkyl substances, and cotinine as a biomarker of tobacco exposure) on neurodevelopmental outcomes in early childhood.
Progress Summary:
During this reporting period, our project team created materials and processes necessary to recruit, train, and enroll child care centers and families and we piloted initial study activities within a child care center. Enrollment officially opened near the end of the reporting period. Participatory science materials were developed to train caregivers to conduct environmental and biological sampling at the participating child’s home. Center sampling kits (water, dust) and home sampling kits (water, dust, hair, saliva, wristbands) were also constructed. Laboratory cleaning methods were piloted and refined for silicone wristbands.
Future Activities:
In the next reporting period, we will advance activities to recruit and enroll up to 300 children in the study area. We will complete study activities related to the first study timepoint, including caregiver interviews, caregiver surveys, the first round of neurodevelopmental assessments, deployment of participatory science sampling kits for caregivers to collect environmental and biological samples at home, and environmental sampling completed by study staff at participating child care centers. We will begin to analyze biospecimen and environmental media samples, and develop results and recommendations reports.
