ObjectivesEmergency department (ED) visits resulting from suicidal thoughts and behaviors have increased at alarming rates among youth in the United States in recent years. Understanding trends among specific racial, ethnic, gender, and/or age subgroups can provide the foundation for tailored solutions for those with the greatest need for support.MethodsUsing data from the Florida State Emergency Department Database from 2016 to 2021, we calculated annual rates of ED suicide‐related diagnoses per 1000 young people aged 8‒21 years. We explored annual trends by age and intersectional race/ethnicity and sex subgroups. Additionally, we examined subgroup‐specific stratified percent changes from 2016 to 2019 and 2016 to 2021.ResultsAmong 8‒12‐year olds, the highest rates of suicide‐related ED encounters occurred among Black males and females and this trend was steady over time. Among 13‒21‐year‐old patients, Black and White females displayed the highest rates of suicide‐related ED encounters across 2016‒2021, and all subgroups experienced a slight decline in 2020 and 2021. Rates generally increased between 2016 and 2019, with the largest percent increase (10.6%) occurring among Black females aged 18‒21 years, whereas there was a trend of decreased rates among most subgroups between 2019 and 2021.ConclusionsAcross all years and age groups, Black females showed consistently higher rates of suicide‐related ED encounters than almost any other subgroup, supporting previous research that Black adolescent females may be disproportionately suffering from the mental health crisis faced by young people. Furthermore, preteen Black males need additional mental health support, as do adolescent and young adult White females.
