Identifying promising themes and messages for youth vaping prevention: A national study

Use of e-cigarettes and vapes among adolescents continues to be a major public health concern. Health communication efforts can discourage e-cigarette use among adolescents by influencing beliefs and behavior. However, to do so, studies need to identify the most promising themes and messages based on the latest evidence about the harms of e-cigarettes and vaping. Participants were a nationally representative sample of 1,603 US adolescents aged 13-17 years, recruited in the summer of 2022. Adolescents were randomly assigned to view 7 vaping prevention statements (one from each theme: nicotine addiction, chemical harms, health symptoms, mental health, organ effects, cosmetic effects, and monetary cost) and 1 control statement (vape litter theme) from a pool of 46 statements that were developed through a systematic process. Participants rated each statement on perceived message effectiveness (PME), awareness, and believability. Results of linear mixed models indicated that all vaping prevention themes out-performed control messages on PME, with chemical harms and organ effects having the largest effects, followed by nicotine addiction and then other themes. For most message themes, PME effects were stronger for youth susceptible to vaping compared to non-susceptible youth and users. Both awareness and believability predicted higher levels of PME. In secondary analyses, we found that statements specifying the target ("you") and longer statements were also rated higher on PME. Results suggests that the most potent vaping prevention messages for adolescents are those that focus on vape chemicals and the potential of vaping to damage organs and increase disease risk.

Trajectories of intimate partner violence and their relationship to stress among young women in South Africa: An HPTN 068 study

BACKGROUND

One in four South African women will experience intimate partner violence (IPV) in their lifetime, potentially increasing their biological stress. In South Africa, limited IPV and stress research has utilized multiple timepoints or examined modifying factors. Cash transfers (CTs) are associated with reduced IPV and stress and may be an intervention target.

AIMS

We used data-driven methods to identify longitudinal IPV trajectory groups among South African adolescent girls and young women (AGYW), estimate each group's association with stress, and assess modification by a CT.

METHODS

A total of 2,183 South African AGYW ages 13 to 24 years from the HIV Prevention Trials Network 068 study were randomized to a CT or control group. Physical IPV was measured five times (2011-2017), and stress was captured once (2018-2019). Stress measures included the Cohen Stress Scale and stress biomarkers (C-reactive protein (CRP), cytomegalovirus (CMV), herpes simplex virus type-1 (HSV-1)). Group-based trajectory modeling identified IPV trajectories; ordinal logistic regression estimated the association between trajectory group and stress.

RESULTS

A two-group quadratic trajectory model was identified (higher trajectory group = 26.7% of AGYW; lower trajectory group = 73.3%). In both groups, the probability of IPV increased from ages 13 to 17 years before declining in early adulthood. However, the higher group's probability peaked later and declined gradually. The higher trajectory group was associated with an increased odds of elevated CRP (OR: 1.41, 95% CI [1.11, 1.80]), but not with other stress measures. The CT modified the relationship with CMV: a positive association was observed among the usual care arm (OR: 1.59, 95% CI [1.11, 2.28]) but not the CT arm (OR: 0.85, 95% CI [0.61, 1.19]).

CONCLUSIONS

Sustained IPV risk during adolescence was associated with elevated CRP in young adulthood. The relationship between IPV and elevated CMV was attenuated among those receiving a CT, suggesting that CTs could possibly reduce biological stress due to IPV.

Potential consequences of the Dobbs v. Jackson Women's Health Organization decision

OBJECTIVE

In June 2022, the U.S. Supreme Court released a landmark decision in which they held that the right to abortion is not protected by the U.S. Constitution, ending almost 50 years of federally legal abortion in the United States. Because prior research demonstrates linkages between reproductive health and substance use at multiple socioecological levels, in this special section, we present studies that take a broad scope to understanding how addictive behaviors and reproduction-related behaviors, options, and access to care interrelate across a variety of contexts.

METHOD

In this introduction, the guest editors detail the impetus for this special section, provide a brief overview of the present studies, discuss policy and intervention implications, and suggest future research directions.

RESULTS

The five studies presented in this special section span a wide range of populations, methods, and substance use and reproduction-related issues, including reasons for past abortions among women with opioid use disorder, alcohol effects on men's condom use resistance, considerations regarding alcohol-involved rape on implementation of "rape exceptions" to abortion bans, the role of early exposure to substance use and sexual abuse on reproductive health outcomes, and the effects of exposure to abortion-related media coverage on alcohol use intentions following the Supreme Court decision.

CONCLUSIONS

The studies in this special section highlight the ways in which substance use and reproductive health are inextricably intertwined. Recent and future changes in reproductive health legislation and policy underscore the critical need for continued empirical inquiry into these intersecting public health concerns.

Impact of visit characteristics on intention to recommend HPV vaccine: An experiment with US health care professionals

OBJECTIVE

Presumptive recommendations that assume parents want to vaccinate can increase human papillomavirus (HPV) vaccine uptake. We sought to examine how visit characteristics affect health care professionals' (HCPs) intention to use this evidence-based recommendation style.

METHODS

In 2022, we conducted an online experiment with 2527 HCPs who had a role in adolescent vaccination in the United States. Participants read 1 of 8 randomly assigned vignettes about a well-child visit. Using a 2 × 2 × 2 between-subjects factorial design, the vignettes varied the following visit characteristics: patient age (9 vs. 12-year-old), prior parental vaccine refusal (yes vs. no), and time pressure on the HCP (low vs. high). HCPs reported on their intention to use a presumptive HPV vaccine recommendation, as well as on related attitudes, subjective norms, and self-efficacy. Analyses used 3-way analysis of variance and parallel mediation.

RESULTS

Participants were pediatricians (26%), family/general medicine physicians (22%), advanced practitioners (24%), and nursing staff (28%). Overall, about two-thirds of HCPs (64%) intended to use a presumptive recommendation. Intentions were higher for older children (b = 0.23) and parents without prior vaccine refusal (b = 0.39, both p < 0.001). Time pressure had no main effect or interactions. HCPs' attitudes and self-efficacy partially mediated effects of patient age and prior vaccine refusal (range of b = 0.04-0.28, all p < 0.05).

CONCLUSION

To better support visits with younger children and parents who have refused vaccines, HCPs may need more training for making presumptive recommendations for HPV vaccine. Reinforcing positive attitudes and self-efficacy can help HCPs adopt this evidence-based recommendation style.
