Electronic Vapor Product Usage and Substance Use Risk Behaviors Among U.S. High School Students

Association between Sexual Violence Victimization and Electronic Vaping Product Use among Adolescents: Findings from a Population-based Study

BACKGROUND

Although studies have investigated the association between sexual violence (SV) victimization and substance use, few studies have examined the association between SV victimization and electronic vaping product (EVP) use among adolescents in the United States. The objective of this study was to examine the cross-sectional association between SV victimization and EVP use among adolescents.

METHODS

Data were pooled from the 2017 and 2019 Youth Risk Behavior Survey. An analytic sample of 28,135 adolescents (51.2% female) was analyzed using binary logistic regression. The outcome variable investigated was EVP use, and the main explanatory variable was SV victimization.

RESULTS

Of the 28,135 adolescents, the prevalence of past 30-day EVP use and SV victimization was 22.7% and 10.8%, respectively. Controlling for other factors, adolescents who experienced SV had 1.52 times higher odds of being EVP users when compared to their counterparts who did not experience SV (AOR = 1.52, p < .001, 95% CI = 1.27-1.82). Other factors associated with EVP use included cyberbullying victimization, symptoms of depression, and current use of cigarettes, alcohol, and marijuana.

CONCLUSIONS

Experiencing SV was associated with EVP use. Future studies that employ longitudinal designs may offer more insight into the mechanisms underlying the association between SV victimization and EVP use. In addition, school-based interventions that focus on sexual violence prevention and reducing substance use among adolescents are warranted.

A Comprehensive Review of Vaping Use in Pediatric Patients and Recent Changes in Regulatory Laws

The use of electronic cigarettes (e-cigarettes), also known as vapes, by adolescents and young adults has dramatically increased over the past several years. E-cigarettes continue to be the most used form of tobacco among youth. As a result of this concerning trend, policies at both the state and federal levels have been implemented to limit availability in this population. Additionally, the coronavirus disease 2019 (COVID-19) pandemic has had some positive and negative effects on the youth vaping epidemic with adolescent consumers reporting limited access to retail sites during the stay-at-home executive orders, but easier access with online purchasing because age verification was often not required. Complications resulting from vaping have been reported and include e-cigarette or vaping product use–associated lung injury (EVALI) and thrombotic events. Data suggest that the use of vaping devices can lead to both short- and long-term respiratory morbidity in the pediatric population. This review serves to provide a comprehensive examination of vaping use in pediatric patients and recent changes in regulatory laws to equip pharmacists with the knowledge to be aware of the different devices and products available, ask their pediatric patients regularly about use, and counsel and educate on the potential harmful effects.

Racial and Ethnic Differences in E-Cigarette and Cigarette Use Among Adolescents

This study examined whether e-cigarette/cigarette use status would differ by student race/ethnicity. Using the 2017 Youth risk behavior survey (YRBS), weighted Chi-square tests with Rao-Scott adjustments and adjusted weighted multinomial logistic regression analysis were conducted to examine the relationship. Weighted Chi-square tests showed that American Indian/Alaska Native (AI/AN) students had the highest prevalence rates among dual users (16.2%) and e-cigarette only users (11.3%), while White peers had the highest prevalence rates among cigarette only users (3.5%). The results of weighted multinomial logistic regression indicated that AI/AN students had higher odds than White peers of being dual users (Relative risk ratio (RRR), 2.10, 95% CI, 1.01, 4.39), while Black, Hispanic, Asian and multi-racial groups had lower odds than White peers of being dual users. Additionally, Asian students had lower odds than White students of being e-cigarette only users, whereas Black and Asian students had lower odds than their White peers of being cigarette only users. Given that AI/AN students are most vulnerable to e-cigarette/cigarette use, there should be comprehensive tobacco prevention and intervention approaches that could narrow racial/ethnic differences among both youths and adults at population level.

Electronic Vapor Product Use and Sexual Risk Behaviors in US Adolescents

BACKGROUND AND OBJECTIVES

Adolescent electronic vapor product (EVP) usage continues to increase and is associated with heightened engagement in other risk behaviors. However, there is limited research on associations between youth EVP use and sexual risk behaviors (SRBs). In this study, we examined how current youth EVP and/or cigarette usage, as well as EVP usage frequency, is related to several SRBs.

METHODS

Respondents (N = 12 667) of the 2017 National Youth Risk Behavior Survey were categorized by previous 30-day EVP and/or cigarette usage: nonuse, EVP use only, cigarette use only, or dual use. Separately, respondents were categorized by previous 30-day EVP usage frequency: 0, 1 to 9, 10 to 29, or 30 days. Ten SRBs were identified as dependent variables. Adjusted prevalence ratios were calculated by using modified Poisson regression to determine associations between SRBs and both current EVP and/or cigarette usage and EVP usage frequency. Linear contrasts compared adjusted prevalence ratios across usage and frequency categories.

RESULTS

Youth EVP-only users and dual users were more likely than nonusers to engage in 9 of 10 SRBs. Prevalence proportions did not differ between EVP-only users and dual users for 7 of 10 behaviors. Occasional EVP users were more likely than nonusers to engage in 9 of 10 SRBs and were similarly as likely as frequent and daily users to engage in all 10 SRBs.

CONCLUSIONS

EVP usage among US high school students, with or without concurrent cigarette use, was associated with heightened engagement in several SRBs. Prevalence of engagement in most SRBs did not differ among occasional, frequent, and daily EVP users.

Where There Is (No) Smoke, There Is Still Fire: a Review of Trends, Reasons for Use, Preferences and Harm Perceptions of Adolescent and Young Adult Electronic Cigarette Use

Purpose of the review

To review the current prevalence, trends, perceptions, and effects of e-cigarette or vaping product use associated lung injury (EVALI) on e-cigarette use among US adolescents and young adults.

Recent findings

COVID-19 diagnosis was more likely among the current/ever dual cigarette and e-cigarettes users, as well as ever e-cigarette only users. Additionally, the EVALI outbreak may have influenced harm perceptions, as daily nicotine vaping declined significantly from 2019 to 2020, and more youth and young adults perceived vaping as harmful.

Summary

The prevalence of e-cigarette use, specifically flavored use, remains high among adolescents and young adults, which is concerning due to the short-term and unknown long-term effects of e-cigarettes and their association with future cigarette and other substance use.

High-School Students Rarely Use E-Cigarettes Alone: A Sociodemographic Analysis of Polysubstance Use Among Adolescents in the United States

INTRODUCTION

Most adolescents reporting e-cigarette use have also used combustible tobacco; however, the extent to which they use other substances is less clear. This study assessed e-cigarette use with tobacco, alcohol, or cannabis and quantified the risk of polysubstance use among adolescents overall and by sociodemographic characteristics.

AIMS AND METHODS

Using 2017 Youth Behavioral Risk Factor Surveillance System data from adolescents (grades 9-12) with complete substance use information (n = 11 244), we examined e-cigarette poly-use status (none [referent], e-cigarettes only, or e-cigarettes + other substances). We estimated the prevalence of substance use and modeled odds of e-cigarette use, alone or with other substances, by several sociodemographic characteristics. Analyses were completed in Stata version 15.1 using survey procedures to account for the complex survey design.

RESULTS

Approximately 12% of adolescents reported past 30-day e-cigarette use. Almost all (93%) e-cigarette users also reported other substance use; alcohol appeared most frequently in combinations. Odds of e-cigarette single use and e-cigarette poly-use (vs. no use) were higher for males and adolescents with lower grades (odds ratios [ORs] = 1.44-2.31). Racial/ethnic minorities had lower odds of e-cigarette poly-use than White peers (ORs = 0.18-0.61), and bisexual (vs. straight) adolescents were more likely to be e-cigarette poly-users (OR = 1.62). E-cigarette use increased from 9th grade (7%) to 12th grade (16%).

CONCLUSIONS

Polysubstance use is highly prevalent among adolescents who use e-cigarettes. Therefore, e-cigarette screening should include the assessment of other substances, especially alcohol. Early and comprehensive prevention efforts to reduce e-cigarette and other substance use could have a substantial beneficial impact on population health over time.

IMPLICATIONS

This study extends knowledge about e-cigarette use among adolescents by exploring its use with alcohol, cannabis, and other tobacco products. We found that e-cigarettes were very rarely used alone, and our analysis identified several sociodemographic factors associated with greater odds of e-cigarette polysubstance use. In response, we recommend that prevention interventions address multiple substances concurrently, screen repeatedly to detect new initiation as age increases, focus on e-cigarette use as a less stigmatized entry point to discussions of substance use, and target priority population subgroups.

The Association Between Risk Behaviors and Vaping Among Youth in New Mexico

CONTEXT

Electronic-cigarette use, or vaping, among youth has increased substantially in recent years. Tobacco smoking shows a strong association with other risk behaviors, but the association between vaping and other risk behaviors has rarely been explored. We examine the relationship between youth vaping and substance use, risky driving behaviors, and lack of bicycle helmet use.

PROGRAM

Data from the 2015 and 2017 New Mexico Youth Risk and Resiliency Survey were analyzed to evaluate the association between the use of e-cigarettes and other youth risk behaviors. Study participants were high school students, grades 9 to 12. Logistic regression models were used to estimate odds ratios (OR) and 95% confidence intervals (CI).

EVALUATION

A majority of students reported ever using e-cigarettes (54%). In 2015, e-cigarette users were more likely than nonusers to be Hispanic (65% vs 54%, P ≤ .001) and 16 years of age or older (58% vs 42%, P = .018). We found strong, statistically significant associations between e-cigarette use and not wearing a bicycle helmet (OR = 2.62, 95% CI: 1.95-3.51), texting while driving (OR = 2.18, 95% CI: 1.79-2.66), driving after drinking (OR = 2.95, 95% CI: 1.61-5.40), current marijuana use (OR = 6.38, 95% CI: 4.65-8.76), current painkiller use (OR = 2.47, 95% CI: 1.63-3.77), and current heroin use (OR = 0.15, 95% CI: 0.06-0.33). Driving after drinking was not significantly associated with e-cigarette use in 2017.

DISCUSSION

E-cigarette use is associated with multiple other risk behaviors among youth. Further research should focus on environmental and policy efforts to reduce access to e-cigarettes by youth as well as interventions that address the underlying causes of the constellation of risk behaviors.

E-cigarette use and concurrent risk behaviors among adolescents

PURPOSE

Although electronic cigarette (e-cigarette) use is on the rise among adolescents, its relationship with risk behaviors is unclear. This study aimed to examine whether e-cigarette use was related to other risk behaviors and whether age and sex play a role in those associations.

METHODS

Data from the 2017 Youth Risk Behavior Surveillance System was used. Weighted logistic regression analysis was conducted to examine the relationships among variables of interest.

FUNDINGS

The results showed that e-cigarette users, compared to nonusers, had higher odds of using other types of substances, as well as being involved in other risk behaviors including driving-related behaviors, sexual activity-related behaviors, and violence-related behaviors. Furthermore, some of these relationships are moderated by age and sex.

DISCUSSION

Our findings suggest that e-cigarette use is linked to other risk behaviors among adolescents. Policy makers and educators should address multiple risk behaviors as part of comprehensive tobacco-free policies and youth substance use prevention programs.

Association of E-cigarettes with adolescent alcohol use and binge drinking-drunkenness: A systematic review and meta-analysis

Background: E-cigarette (ECIG) use has increased substantially in the past decade. Co-use of alcohol and ECIGS may have serious consequences in adolescents. Objectives: To evaluate the association of e-cigarettes (ECIGs) with alcohol use in adolescents. Methods: Searched databases included PubMed, EMBASE, CINAHL, PsycINFO, Web of Science, and gray literature. Studies were included if they contained a non-E-cigarette group (NON-ECIG), an ECIG group, detailed rates of alcohol use, binge drinking, or drunkenness and included adolescents. Two independent reviewers extracted data using MOOSE guidelines. Evidence quality across studies was assessed using Cochrane GRADE methodology. Summary effects of ECIG vs. NON-ECIG use on any alcohol use and a composite of binge drinking/drunkenness were calculated using a random-effects model. Results: 28 of 3768 initially identified studies were included: 25 cross-sectional, 3 cohort studies, N = 458,357 total subjects (49.6% females). Pooling of data showed that ECIG users had a higher risk for any alcohol use compared to NON-ECIG users (Odds Ratio/OR 6.62, 95% confidence interval/CI 5.67-7.72) and a higher rate of binge drinking/drunkenness compared to NON-ECIG users (OR 6.73, 95% CI 4.5 - 10.07). The subset of high school ECIG users had higher rates of alcohol use (OR 8.17, 95% CI 5.95-11.2) and binge drinking/drunkenness (OR 7.98, 95% CI 5.98-10.63) compared to NON-ECIG users. Conclusion: ECIG users had a higher risk of alcohol use and binge drinking/drunkenness compared to NON-ECIG users. Our findings indicate that interventions to reduce ECIG use should be coupled with measures to reduce alcohol use in adolescents.Abbreviations: ECIG: e-cigarettes; NON-ECIG: non e-cigarettes.
