## Abstract

PROJECT SUMMARY – Parent UH3 OD023272
We propose to integrate two pregnancy cohorts currently under recruitment at the University of Illinois and the
University of California, San Francisco (UCSF) to form a larger geographically, socio-economically, racially and
ethnically diverse cohort (ECHO.CA.IL) to study the cumulative impact of chemical exposures and maternal
psychosocial stress on birth outcomes and early neurodevelopment. We will focus on two groups of
highproduction volume endocrine disrupting chemicals (EDCs) regularly detected in pregnant women, which
research suggests may impact development, but for which data on child health outcomes is sparse: phenols
(bisphenols, benzophenone, dichlorophenols, parabens, triclosan, triclocarban) and perfluorinated alkyl
substances (PFAS). We will measure three indices of chronic stress and resilience: 1) Perceptual - perceptions
of social standing and stress exposures in household, neighborhood, and work environments; 2) Place-based
– neighborhood level socioeconomic status, civic engagement, green space and built environment; and 3)
Biomarkers - telomere length in maternal and umbilical cord leukocytes and corticotropin releasing hormone
(CRH) levels in maternal plasma. We will measure birth outcomes (birth weight and gestational age) and we
will use innovative approaches to assess basic cognitive functions including working memory, attention,
information processing, and social cognition in infancy and early childhood. We will address three specific
aims: (1) Evaluate the relationship between prenatal exposures to EDCs and measures of adverse birth
outcomes and cognitive development of offspring. (2) Evaluate the relationship between measures of prenatal
stress and measures of adverse birth outcomes and cognitive development of offspring. Importantly, for this
aim we will also assess whether biomarkers of stress response mediate the relationship between perceptual
and place-based stress and developmental outcomes. (3) Evaluate whether maternal stress modifies observed
relationships between EDC exposures and measures of adverse birth outcomes or cognitive development of
offspring. During the planning period, we will harmonize data collection and management (including
biospecimens, stress measurements, and measurements of birth outcomes and cognitive functions) across our
two cohorts to prepare for merging our two data sets and for sharing our data with the ECHO Data Analysis
Center. During UG3 stage we will also actively participate in development and implementation of the ECHO-
wide study protocol contributing expertise and methodology for assessing maternal stress, offspring cognitive
development and our experiences integrating and harmonizing data collection across our two geographically
distinct pregnancy cohorts. In summary, our innovative research approach will contribute to ECHO by providing
a framework for integrating cumulative chemical exposures with chronic psychosocial stress and sources...
