What this research studies

We will invite pregnant people in the San Francisco Bay Area to join the existing Chemicals in Our Bodies (CIOB) pregnancy cohort and expand the group. Participants complete surveys and provide biospecimens during pregnancy and for their children so researchers can measure about 200 chemicals, including phthalates, pesticides, and aromatic amines. The team will share individual chemical results back with participants and make de-identified cohort data available to other researchers and community end-users. Follow-up of children will link prenatal exposures and social stressors to pregnancy and child health outcomes.

Who could benefit from this research

Good fit: Pregnant people in the San Francisco Bay Area—especially those in the second trimester—who can complete surveys, provide biospecimens, and allow follow-up of their children are ideal candidates.

Not a fit: People who are not pregnant, who live far from the Bay Area, or who are unwilling to provide biospecimens or follow-up data are unlikely to benefit from participation.

Why it matters

Potential benefit: Participants could learn their personal chemical exposure levels and receive information that may help reduce exposures and support healthier pregnancies and child development.

How similar studies have performed: This builds on the existing CIOB cohort and other pregnancy cohorts in the ECHO program that have successfully measured chemical exposures and linked them to child health outcomes.
