Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The DREAM Cohort is a longitudinal observational study developed to enhance our understanding of how multiple exposures to environmental chemicals and pollutants across a diverse population of pregnant women and their offspring are linked to cancer risks. Because pregnancy induces multiple maternal hormonal and physiological changes that can increase cancer susceptibility to environmental chemical exposures, this study will focus on pregnancy as a period of particular vulnerability to toxic agents.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The environmental exposures will focus on two major components: Consumer product related chemicals (including per- and polyfluoroalkyl substances (PFAS), phthalates and plasticizers, phenolic compounds, pesticides, and aromatic amines) measured via biomonitoring and prioritized based on widespread public exposure; and environmental pollutants in air and water, evaluated via geographic information system analyses of participants' residential histories.

The study team will collect questionnaire data and biospecimen samples starting at the second trimester of pregnancy up until the child reaches four years of age. A Cohort Ambassador Program will also be established to invite participants across our three sites to provide continuous feedback which will be integrated into the research priorities.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Pregnant women and their children

The DREAM cohort will recruit from University of California, San Francisco (UCSF) Mission Bay, Zuckerberg San Francisco General Hospital, and Fresno Community Medical Center locations to enroll an economically, geographically, ethnically and racially diverse cohort of pregnant women and their children for long term follow-up.

Health Questionnaires

Intervention Type OTHER

A questionnaire with content developed and tested in the investigator's previous reproductive and cancer epidemiology studies as part of the NIH Environmental Influences on Child Health Outcomes (ECHO) consortium will be used to collect information on primary established and hypothesized risk factors for cancer and additional covariates.

Specimen sample collection

Intervention Type OTHER

Collection of blood, urine, nails, hair, and saliva samples will be obtained during the participant encounters.
