Adverse childhood experiences (ACEs) portend vulnerability to numerous physical and mental health concerns across the lifespan. Separate bodies of work suggest that both lesbian, gay, bisexual, and queer (LGBTQ+) individuals and military veterans are more likely to report ACEs compared to their non-LGBTQ+ and non-veteran counterparts, respectively. Although LGBTQ+ veterans experience health disparities compared to non-LGBTQ+ veterans, prevalence of ACEs among individuals with both LGBTQ+ and veteran identities is yet unknown. Participants were US military veterans (N = 14,461) from 18 states that included Sexual Orientation and Gender Identity and ACEs modules in the 2019 and 2020 Behavioral Risk Factor Surveillance System survey. Multivariable logistic regression was used to determine odds of ACEs reported by LGBTQ+ veterans compared with non-LGBTQ+ veterans. Analyses were conducted in 2023. While accounting for socio-demographic factors, LGBTQ+ veterans were more likely to report living with someone who experienced mental illness (aOR = 2.17, 95%CI, 1.35-3.51); emotional abuse (aOR = 1.58, 95%CI, 1.11-2.25); and sexual abuse (aOR = 2.21, 95%CI, 1.29-3.76) compared to non-LGBTQ+ veterans. With past work indicating that childhood abuse experiences are especially predictive of adverse health in adulthood, our findings suggest that a higher prevalence of ACEs among LGBTQ+ veterans may contribute to health disparities among this population.
