Adverse Childhood Experiences and Tobacco Use Patterns Among Adults in the United States: Exploring sex differences

Objective Adverse childhood experiences (ACEs), which refer to childhood traumatic events, have been identified as risk factors for tobacco use in adulthood. However, studies are limited on the effect of sex on the association of ACEs with e-cigarettes and dual use of e-cigarettes and cigarettes. This study explored sex differences in the association of ACEs with e-cigarettes, cigarettes, and dual use of e-cigarettes and cigarettes among adults in the United States. Methods This was a cross-sectional analysis of data from adults aged >= 18 years in the 2020 Behavioral Risk Factor Surveillance System (N = 62,768). ACEs, the independent variable, was a composite score assessed from 11 questions (with responses yes-1 or no/never-0) related to childhood emotional abuse, physical abuse, sexual abuse, and household dysfunction and categorized as 0 (reference), 1, 2, 3, or >= 4. The dependent variable, tobacco use patterns, included nonuse (reference), e-cigarette only, cigarette only, and dual use of e-cigarettes and cigarettes. Multinomial logistic regression was performed to test the interaction between sex and ACEs while controlling for potential confounders. Results Although we found no statistically significant interaction by sex, a greater number of ACEs were associated with higher odds of the different tobacco use patterns among females and males, with varying strengths of associations. Specifically, females who reported >= 4 ACEs compared with none had higher odds of e-cigarette (aOR [95% CI]: 3.58 [1.49-8.63]), cigarette (2.57 [1.72-3.83]) and dual use (3.25 [1.79-5.91]) relative to nonuse. Males with >= 4 ACEs had higher odds of cigarette (1.75 [1.15-2.65]) and dual use (7.64 [3.95-14.79]). Conclusion Our findings underscore the importance of developing appropriate, tailored trauma-informed intervention strategies for females and males. It is also important to consider ACEs in designing tobacco-specific preventive programs to curb initiation and promote cessation among U.S. adults.

Automated summary

This study investigated the sex differences in the association between adverse childhood experiences (ACEs) and e-cigarettes, cigarettes, and dual use of e-cigarettes and cigarettes. Although no statistically significant interaction by sex was found, a greater number of ACEs were associated with higher odds of different tobacco use patterns among females and males. Therefore, it is important to develop appropriate, tailored trauma-informed intervention strategies for females and males.
