Columbia Center for Children’s Environmental Health Sibling-Hermanos cohort (CCCEH S/H)
The CCCEH Sibling/Hermanos (S/M) cohort includes 125 younger siblings of the children from the CCCEH Mothers and Newborns (MN) cohort. Beginning in 2008, African American and Dominican women residing in low-income New York City neighbourhoods in the United States of America who were participants in the MN cohort were invited to enrol in the S/M cohort if they became pregnant with another child. Similar to the MN study, the women were enrolled if they had a prenatal visit by the 20th week of pregnancy, and were not active smokers or illicit drug users. The children born into the S/M cohort are being followed-up from birth until age 7 with same protocol as the MN cohort to further examine the relationships between environmental exposures and health outcomes compared with their older siblings in the MN cohort.
