Previous studies have well-documented that adverse childhood experiences (ACEs) are associated with negative health outcomes, including suicidal thoughts and behaviors. As historically marginalized groups have long experienced poorer socio-emotional outcomes due to systemic and institutional racism, racial stress, and related factors, surprisingly little is known about how ACEs matter across racial/ethnic adolescent groups. This study aims to fill this gap by analyzing data from the 2022 Florida Youth Substance Abuse Survey (FYSAS). Utilizing logistic regression models, we investigate how ACEs influence adolescent suicidal thoughts and behaviors. Results reveal a significant link between ACEs and these outcomes, indicating that higher ACE scores correlate with increased risk of suicidal thoughts and attempts. Racial/ethnic variations in ACE effects on suicidality are observed among non-Hispanic Black and Hispanic/Latinx youth. We also find that despite generally experiencing fewer ACEs, Asian American youth were nearly 30% more likely to have suicidal thoughts than non-Hispanic White youth.
