Sexual Identity Is Associated With Adverse Childhood Experiences in US Early Adolescents.

Objective: To determine disparities in adverse childhood experiences (ACEs) by sexual identity in a national cohort of early adolescents.

Methods: We analyzed cross-sectional data from year 2 of the Adolescent Brain Cognitive Development study (N = 10,934, 2018-20, ages 10-14 years). Disparities in ACE scores across lesbian, gay, or bisexual (LGB), not sure, and heterosexual adolescents were assessed using multinomial logistic regression analyses. Logistic regressions estimated the associations between sexual identity and each individual ACE. Analyses were adjusted for potential confounders.

Results: In adjusted models, LGB adolescents had a higher risk of experiencing 2, 3, or ≥4 ACEs (relative risk ratios [RRR] = 1.57, 95% Confidence Interval (CI) 1.01-2.42), 3 (RR = 1.78, 95% CI 1.100-2.88), or ≥4 ACEs (RRR = 3.20, 95% CI 1.92-5.32), and not sure adolescents had a higher risk of having ≥4 ACEs (RRR = 2.17, 95% CI 1.22-3.87), compared to heterosexual adolescents. LGB and not sure adolescents had higher risks of reporting emotional abuse ("yes" OR = 4.21, 95% CI 1.84-9.61; "maybe" OR = 6.20, 95% CI 2.91-13.19) and parent mental illness ("yes" OR = 1.95, 95% CI 1.48-2.57; "maybe" OR = 1.63, 95% CI 1.21-2.18) compared to heterosexual adolescents.

Conclusions: LGB adolescents and those questioning their sexual identity were at greater risk of having higher ACE scores, with LGB adolescents experiencing the highest risk of experiencing ACEs. LGB adolescents also had higher odds of reporting emotional and parent mental illness. Recognizing this heightened risk of ACEs in early adolescence is critical for designing clinic and school-based interventions.
