Adverse Childhood Experiences Study

The Adverse Childhood Experiences Study (ACE Study) is a research study conducted by Kaiser Permanente health maintenance organization and the Centers for Disease Control and Prevention (CDC). Participants were recruited to the study between 1995 and 1997 and have been in long-term follow up for health outcomes. The study has demonstrated an association of adverse childhood experiences (ACEs) with health and social problems as an adult. The study has been analyzed extensively, is frequently cited as a notable landmark in epidemiological research, and has produced more than 50 scientific articles and more than 100 conference and workshop presentations that look at the prevalence and consequences of ACEs.
