MedicalResearch.com: What is the background for this study?
Response: My co-authors and I conducted this study to fill a knowledge gap and to inform the work of Project TENDR. No systematic or scoping review had examined both exposure disparities and the joint effects of combined exposures of environmental neurotoxicants and social disadvantage as they relate to disparities in neurodevelopmental outcomes specifically among children living in the U.S.
Our study is the first to summarize the evidence on 7 neurotoxicants that children in the U.S. are routinely exposed to and we examined both disparities in these exposures and disparities in the effects of those exposures on children’s brain development, cognition, and behavior by race, ethnicity, and economic status.
We reviewed over 200 independent studies spanning five decades from 1974 to 2022 on social disparities in exposure to 7 exemplar neurotoxic chemicals and pollutants, including chemical mixtures, and their relationship with disparities with neurodevelopmental outcomes among children in the U.S.
