Background Suicide attempts and deaths among children are increasing in the United States, yet suicide this preadolescent population remains understudied. A clearer understanding of which youth experience early onset suicidal behavior is crucial for predicting risk identifying best suited to intervention. This paper examines how intersectional marginalized identities may predict behaviors youth. Methods The Adolescent Brain Cognitive Development (ABCD) Study a prospective cohort study with annual assessments ages 9 10 their caregivers. Lifetime preparatory were assessed annually. Survival models examined overall trends demographic differences behaviors. Results final sample included 11,223 participants (mean age = 9.9 years old, SD 7.5 months). 5,280 (47%) reported minoritized racial/ethnic identity, 1,410 (12.6%) categorized as sexual or gender minorities. 208 143 instances across period. An interaction effect was found such that who hold multiple (i.e., minority from backgrounds) at elevated both (HR 2.97, 95% CI 1.59–5.56, p .001) ( b 3.09, 1.38–6.93, .006). Conclusions Intersectional associated earlier Findings suggest interventions be important reduce rapidly rate
