This essay by Amanda Jichlinsky, published in Pediatrics, discusses how Adverse Childhood Experiences (ACEs) are detrimental to children, adults, and communities because of their effect on behavioral health and long-term outcomes. Genetic make-up and individual resilience mediate the relationship between ACEs and health outcomes. Physicians play a role as community members in identifying children at risk, creating a network of support, and building a community that promotes change. When change is slow, pediatricians should not underestimate their power to inspire, promote, and create positive change.
