Abstract The Columbia Center for Children’s Environmental Health (CCCEH) has three multi-ethnic birth cohorts contributing to the ECHO Consortium. Children in our cohorts live in the lower income Northern Manhattan and South Bronx neighborhoods of New York City and are comprised of African American and Hispanic women and their children. As described in this supplemental application, we respectfully request additional funding in year 7 to achieve our EWCP milestones and goals. These funds would go principally to increase our staff effort-- many of whom are bilingual (English/Spanish) and from the same cultural background, ethnicity, and neighborhoods in which the participants live. The additional funds requested in this supplement will ensure that we can continue to provide extant and newly collected EWCP data from our three cohorts and will create a more equitable situation among all of the ECHO cohorts. With the provision of these additional resources, we will preserve our ability as ECHO members to exert a sustained, powerful influence on the research fields involved and will support the inclusion and representation of diverse participants in ECHO who are traditionally under- represented in research.
