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.

Technology-Based Interventions in Substance Use Treatment to Promote Health Equity Among People Who Identify as African American/Black, Hispanic/Latinx, and American Indian/Alaskan Native: Protocol for a Scoping Review

BACKGROUND

Technology-based interventions (TBIs; ie, web-based and mobile interventions) have the potential to promote health equity in substance use treatment (SUTx) for underrepresented groups (people who identify as African American/Black, Hispanic/Latinx, and American Indian/Alaskan Native) by removing barriers and increasing access to culturally relevant effective treatments. However, technologies (emergent and more long-standing) may have unintended consequences that could perpetuate health care disparities among people who identify as a member of one of the underrepresented groups. Health care research, and SUTx research specifically, is infrequently conducted with people who identify with these groups as the main focus. Therefore, an improved understanding of the literature at the intersection of SUTx, TBIs, and underrepresented groups is warranted to avoid exacerbating inequities and to promote health equity.

OBJECTIVE

This study aims to explore peer-reviewed literature (January 2000-March 2021) that includes people who identify as a member of one of the underrepresented groups in SUTx research using TBIs. We further seek to explore whether this subset of research is race/ethnicity conscious (does the research consider members of underrepresented groups beyond their inclusion as study participants in the introduction, methods, results, or discussion).

METHODS

Five electronic databases (MEDLINE, Scopus, Cochrane Library, CINAHL, and PsycInfo) were searched to identify SUTx research using TBIs, and studies were screened for eligibility at the title/abstract and full-text levels. Studies were included if their sample comprised of people who identify as a member of one of the underrepresented groups at 50% or more when combined.

RESULTS

Title/abstract and full-text reviews were completed in 2021. These efforts netted a sample of 185 studies that appear to meet inclusionary criteria. Due to the uniqueness of tobacco relative to other substances in the SUTx space, as well as the large number of studies netted, we plan to separately publish a scoping review on tobacco-focused studies that meet all other criteria. Filtering for tobacco-focused studies (n=31) netted a final full-text sample for a main scoping review of 154 studies. The tobacco-focused scoping review manuscript is expected to be submitted for peer review in Spring 2022. The main scoping review data extraction and data validation to confirm the accuracy and consistency of data extraction across records was completed in March 2022. We expect to publish the main scoping review findings by the end of 2022.

CONCLUSIONS

Research is needed to increase our understanding of the range and nature of TBIs being used in SUTx research studies with members of underrepresented groups. The planned scoping review will highlight research at this intersection to promote health equity.

Baseline Cigarette Smoking Status as a Predictor of Virologic Suppression and CD4 Cell Count During One-Year Follow-Up in Substance Users with Uncontrolled HIV Infection

Cigarette smoking is prevalent in people living with HIV/AIDS (PLHIV) who abuse alcohol and/or illicit substances. This study evaluated whether smoking is predictive of virologic non-suppression (> 200 copies/mL) and low CD4 count (< 200 cells/mm³) during 1-year follow-up in medically hospitalized, substance-using PLHIV recruited for a multi-site trial. Smoking status was assessed with the Heaviness of Smoking Index (HSI). Analyses revealed that, controlling for baseline differences and adherence to antiretroviral therapy, non-smokers (n = 237), compared to smokers scoring in the medium-to-high range on the HSI (n = 386), were significantly more likely to achieve viral suppression (OR 1.50, 95% CI 1.02, 2.20). There was a significant smoking-by-time interaction for CD4 cell count (χ²(1) = 4.08, p < .05), with smokers less likely to have low CD4 count at baseline and 6-month follow-up, but more likely to have low CD4 count at 12-month follow-up. The results suggest that smoking may play a role in immunological functioning in HIV-infected substance users. ClinicalTrials.gov Identifier: NCT01612169.
