Adverse childhood experiences during the COVID-19 pandemic and associations with poor mental health and suicidal behaviors among high school students: Adolescent behaviors and experiences survey, United States, January-June 2021

What is already known about this topic? Adverse childhood experiences (ACEs) are associated with poor mental health and suicidal behaviors. What is added by this report? The prevalences of poor current mental health and past-year suicide attempts among adolescents reporting four or more ACEs during the COVID-19 pandemic were four and 25 times as high as those without ACEs, respectively. Exposure to specific ACE types (e.g., emotional abuse) were associated with higher prevalences of poor mental health and suicidal behaviors. What are the implications for public health practice? Primary prevention and intervention strategies for ACEs and their acute and long-term impacts, including early identification and trauma-informed mental health service and support provision, could help address the U.S. child and adolescent mental health and suicide crisis.
