The team from Rutgers Health plans to recruit up to 500 pregnant participants who are less than 20 weeks from conception from RWJ University Hospital and St. Peter’s University Hospital, both in New Brunswick, N.J., into the ECHO Cohort, a nationwide research study including sites across the U.S. The researchers will follow the participants, their partners and children for seven years, tracking factors such as obesity, neurodevelopment, exposure to environmental chemicals and positive health through biosamples and surveys.
