IntroductionThe use of e-cigarettes or other electronic vaping products (EOEVP) has been on the rise since their introduction. Concurrently, Adverse Childhood Experiences (ACEs) have been linked to various negative behavioral health outcomes. We explore the association between ACEs and current EOEVP use, with a focus on variations across sex, race/ethnicity, and age.MethodsUtilizing data from the Behavioral Risk Factor Surveillance System (BRFSS) for 2020–2022, we analyzed responses from 202,126 adults in the United States in a cross-sectional study. Multivariable logistic regression models were used to evaluate the adjusted odds ratios (aORs) of current EOEVP use for different levels of ACEs. Stratified and interaction analyses were used to examine potential effect modification.ResultsAmong adults 54 years of age and younger, even a lower number of ACEs [1 (aOR 1.52), 2 (aOR 2.01), and 3 (aOR 1.51)] was associated with higher odds of current EOEVP use. Stratified analyses revealed significant differences in the odds of current EOEVP use among Non-Hispanic White adults between 1 ACE (95% CI 1.75–2.28) and 4 ACEs (2.34–3.17). Hispanic adults with ≥ 1 ACEs (p-value 0.001) and 8 ACEs (p-value 0.005) showed strong associations compared to Non-Hispanic White adults. The influence of ACEs on current EOEVP use was observed to decrease with age, particularly in older adults with fewer ACEs. The aORs did not very by sex.ConclusionThe findings emphasize the importance of considering any number of ACEs in public health strategies targeting current EOEVP use, especially among younger adults and specific minority groups. These insights are crucial for tailoring interventions and policies to address the nuanced impacts of early life adversities on health risk behaviors.
