The Environmental Influences on Child Health Outcomes (ECHO)-Wide Cohort

Area of Science:

• Pediatric Health Research
• Environmental Epidemiology
• Child Development Studies

Background:

• The National Institutes of Health (NIH) funded the ECHO-Wide Cohort Study (EWC) in 2016.
• The EWC is a large-scale, collaborative research effort involving 69 cohorts across 31 consortia.
• The study aims to enhance understanding of children's health in the United States.

Purpose of the Study:

• To harmonize existing data and collect new data using a standardized protocol (EWCP).
• To investigate the impact of environmental exposures on child health outcomes.
• To improve children's health through comprehensive data collection and analysis.

Main Methods:

• Utilizes the ECHO-Wide Cohort Data Collection Protocol (EWCP) with varying visit frequencies across cohorts.
• Collects data through surveys, interviews, standardized examinations, laboratory analyses, and medical record abstraction.
• Gathers information on exposures at individual, family, and neighborhood levels, including air pollution, socioeconomic status, parental mental health, diet, and genomics.

Main Results:

• As of March 4, 2022, data from 60,553 children were contributed.
• 29,622 children were consented for new EWCP data and biospecimen collection.
• The median age of enrolled children was 7.5 years (IQR: 3.7-11.1).

Conclusions:

• The EWC is establishing a robust dataset to examine environmental influences on child health.
• The study focuses on key outcome areas: prenatal/perinatal/postnatal outcomes, neurodevelopment, obesity, airways, and positive health.
• Findings will inform strategies to improve pediatric health outcomes by understanding environmental determinants.
