Navajo Birth Cohort Study (NBCS)
The NCBS aims to better understand the relationship between uranium and environmental metal exposures with birth outcomes and children’s development on the Navajo Nation in the United States of America. From 2019, NCBS has been included in the Environmental influences on Child Health Outcomes (ECHO) program, allowing it to study a broader set of health outcomes that include obesity, upper and lower airway function, birth outcomes, neurodevelopment and overall health. Participants are around 1,000 mother-child dyads recruited while the women were pregnant from maternity health services in the Navajo Nation. Since 2013, pregnant women have completed a baseline assessment at enrolment, and their children have been assessed at birth, with annual follow-ups until the child is nine years old.
