Observational studies (ECHO Cohorts)

Observational Studies (ECHO Cohort)

The ECHO Program (ECHO) aims to enroll more than 50,000 children through its observational studies. ECHO brings together participants of different races, genders, ages, and backgrounds to better understand the effects of environmental influences on child health and development. This branch of ECHO research is observational. ECHO researchers use the cohort to look at the effects of early environmental influences on children over time.

The ECHO Cohort has observed children for many years. By joining together in the ECHO Program, researchers have access to a wealth of data to answer important questions. ECHO researchers will also continue to collect new information from participants as part of the cohort's ongoing research.

The Cohort Study Sites collect data in a similar way to make sure all information can be combined and utilized by researchers. Study sites are spread across the United States, including Puerto Rico. Learn more about study site locations by visiting the ECHO map.
