What are the main findings?
The revised ACE Pyramid incorporates more than two decades of advances in the science of toxic stress while preserving the familiar structure of the original framework.
The revised framework positions prolonged or excessive activation of the stress response as a central mechanistic pathway linking childhood adversity to lifelong health outcomes.
What are the implications of the main findings?
The framework supports a shift from viewing ACEs primarily as risk indicators toward understanding and addressing toxic stress biology as a target for prevention and intervention.
It provides a shared framework for informing pediatric practice, public health, research, and policy aimed at improving outcomes for children and families.
