Project Summary/Abstract
The Environmental Influences on Child Health Outcomes (ECHO) program capitalizes on diverse pregnancy and
pediatric cohorts to investigate the impact of a broad array of environmental influences on child health and
development. Since 2016, the Developmental Impact of NICU Exposures (DINE) study has significant
contribution of the to the ECHO mandate is a large, exquisitely phenotyped preterm birth cohort - a unique and
sensitive population with a demonstrated large burden of adverse health outcomes. The DINE cohort readily
combines rich existing clinical and research datasets and biospecimen repositories, existing infrastructure for
long-term follow up and assessments of multiple ECHO exposure and outcome specialization areas, and a novel
exposure and outcome profile that will continue high-yield contribution to ECHO program scientific goals.
In this second phase of the ECHO program, we will continue to focus on the scientific premise that early life
physical and chemical exposures, notably phthalates and air pollution, have long-lasting harmful effects on child
health and development, and that these harmful effects are magnified in children born preterm. DINE contributes
a unique and critically important population to ECHO in that preterm infants face significant dermal, inhalational
and intravenous exposures to phthalates, ubiquitous organic endocrine disrupting chemicals, while hospitalized
the neonatal intensive care unit (NICU). Premature infants experience a high prevalence of the adverse health
effects that are associated with early life exposure to phthalates in term-born children, particularly abnormalities
of pulmonary function. The contribution of environmental influences on adverse outcomes of preterm children is
poorly understood. One additional central tenet of our work is that preterm infants can be studied to identify
exposure-outcome links that may be more subtle in the general population. Large clinical studies like ECHO that
enroll participants born over the entire preterm-to-term continuum allow rigorously study of this premise.
Through the next phase of the ECHO program, we pursue the following Specific Aims in DINE:
Aim 1. Leverage ECHO Cohort Protocol core data elements to compare exposure-outcome
relationships in preterm compared to term populations.
Aim 2. Leverage specialized data elements to address critical questions about the impact of early
life chemical exposures on pulmonary development in a sensitive population, preterm infants.
Aim 3. Implement procedures to maximize retention of existing participants with an emphasis on
maintaining cohort diversity and protocol fidelity.
Continued involvement of preterm infants in ECHO is critical not only to our cohort’s scientific imperatives, but
also to the entire ECHO program as preterm infants constitute more than 10% of the United States population.
