Developing a National Longitudinal Tobacco Cohort of Youth and Young Adults: The Tobacco Epidemic Evaluation Network (TEEN+) Study.

Introduction: Timely and relevant data are critical to monitoring the rapidly changing youth vaping epidemic and for understanding the prevalence, patterns of use, knowledge, and perceptions of tobacco products. While e-cigarettes have been the most used tobacco product among youth for nearly a decade, new nicotine delivery products continue to be introduced to the US market. Flavored tobacco products, including flavored e-cigarettes, menthol cigarettes, and flavored cigars, drive disparities in use by young people.

Pathways to prevent e-cigarette use: Examining the effectiveness of the truth antivaping campaign.

Objective: Mass media campaigns have been designed to counter a rise in e-cigarette use among young people. No studies to date have established pathways from campaign exposure to e-cigarette use behaviors. This study examines the mechanisms through which exposure to the truth® campaign may prevent the progression of e-cigarette use among youth and young adults.

Improving the Efficiency of Inferences From Hybrid Samples for Effective Health Surveillance Surveys: Comprehensive Review of Quantitative Methods.

Background: Increasingly, survey researchers rely on hybrid samples to improve coverage and increase the number of respondents by combining independent samples. For instance, it is possible to combine 2 probability samples with one relying on telephone and another on mail. More commonly, however, researchers are now supplementing probability samples with those from online panels that are less costly.

Pathways to Quitting E-cigarettes Among Youth and Young Adults: Evidence From the truth® Campaign.

Purpose: This study examines the pathways through which e-cigarette users' awareness of the truth® campaign influences e-cigarette use frequency over time.

Design And Setting: Data included four waves (2020-2023) of the Truth Longitudinal Cohort, a probability-based, nationally representative survey.

Participants: The analytic sample was 15-24-year-olds who reported current e-cigarette use at baseline (N = 718).

Youth and Young Adult Blunt Use Predicts Progression to Other Nicotine Product Use in the United States.

Background: Little cigars or cigarillos (LCCs) are frequently modified to smoke cannabis ("blunts") by youth and young adults. This study investigated whether young blunt users who are otherwise nicotine-naïve are more likely to initiate other tobacco products compared to never blunt users.

Methods And Materials: Data were from four waves of the Truth Longitudinal Cohort (TLC), a national probability-based sample of youth and young adults (aged 15-24 years) in the United States (Wave 1: January-April 2017; Wave 2: February-May 2018; Wave 3: February-May 2019; Wave 4: September-December 2019).

Reducing e-cigarette use among youth and young adults: evidence of the truth campaign's impact.

Background: Mass media campaigns have been shown to be effective in reducing cigarette use. However, evidence is limited for whether campaigns can shift e-cigarette use among youth and young adults (YYA). To assess the impact of the truth anti-e-cigarette campaign, which focused on the effects of vaping on mental health, this study examines the relationship between campaign awareness and e-cigarette behaviour among YYA.

Content analysis of tobacco imagery in popular music Videos, 2018-2021.

Exposure to tobacco imagery in movies and television has been identified as a key factor to youth smoking initiation (Davis, 2008; Bennett et al., 2020). This study aims to investigate the prevalence of tobacco imagery in popular music videos from 2018 to 2021.

Checkpoint Travel Numbers as a Proxy Variable in Population-Based Studies During the COVID-19 Pandemic: Validation Study.

Background: The COVID-19 pandemic had wide-ranging systemic impacts, with implications for social and behavioral factors in human health. The pandemic may introduce history bias in population-level research studies of other health topics during the COVID-19 period.

Objective: We sought to identify and validate an accessible, flexible measure to serve as a covariate in research spanning the COVID-19 pandemic period.

A resurgence of e-cigarette use among adolescents and young adults late in the COVID-19 pandemic.

Background: Early in the COVID-19 pandemic, e-cigarette use significantly declined among young people due, in part, to losing access through social sources. As the pandemic progressed, adolescents and young adults gained opportunities to resume contact with peers. This study sought to determine whether e-cigarette use has returned to pre-pandemic levels among adolescents and young adults.

Perceived Sensory Characteristics of Blended and Ambiguous "Concept" Flavors Among Adolescent and Young Adult E-cigarette Users.

Introduction: Flavors with names describing blended tastes/sensations or with ambiguous terminology ("concept flavors") are available on the e-cigarette market.

Aims And Methods: This study investigates adolescent and young adult use and sensory perceptions of blended and concept flavors. Current e-cigarette users aged 15-24 years (N = 2281) completed an online convenience sample survey (October 20-November 23, 2020) and rated the sensory attributes (fruity, cooling, sweet, and minty) of their current flavor(s) using nine-point scales.

Relative increases in direct-to-consumer menthol ads following 2020 FDA guidance on flavoured e-cigarettes.

Objective: To examine potential changes in email and direct mail advertisements for flavoured e-cigarettes following the 2020 Food and Drug Administration (FDA) flavour guidance.

Methods: Digital copies of e-cigarette advertisements were obtained from Mintel Comperemedia (November 2019-May 2020) and coded for the presence of flavours. Χ tests were used to determine changes in the prevalence of email and direct mail advertisements for e-cigarettes with menthol, non-menthol and no flavours.

Influence of Flavors and Nicotine Concentration on Nicotine Dependence in Adolescent and Young Adult E-Cigarette Users.

The objective of this study is to examine the relationships between e-cigarette flavors, nicotine concentration, and their interaction on measures of nicotine dependence. Survey data are drawn from a cross-sectional convenience sample of past 30-day e-cigarette users aged 15 to 24 years (N = 2037) collected between October 2020 and November 2020. Participants were asked to provide information about the e-cigarette products they used most regularly.

Early evidence of the associations between an anti-e-cigarette mass media campaign and e-cigarette knowledge and attitudes: results from a cross-sectional study of youth and young adults.

Objective: Antismoking mass media campaigns have contributed to significant declines in combustible tobacco use among young people. This study evaluates a national anti-e-cigarette campaign to determine its association with knowledge, attitudes and beliefs in the context of increasing e-cigarette use in the USA.

Methods: A national sample of respondents aged 15-24 years (n=8421) was drawn from a repeated cross-sectional online panel survey (220 participants/week) (October 2018 to December 2019).

Evidence of the impact of a national anti-tobacco prevention campaign across demographic subgroups.

Mass media campaigns are an effective population-level intervention for preventing tobacco use. However, little evidence exists for whether these campaigns similarly influence demographic subgroups. This study examined the effects of the truth® campaign to reduce tobacco use among demographic subgroups.

A longitudinal analysis of e-cigarette use and cigar, little cigar or cigarillo initiation among youth and youth adults: 2017-2019.

Purpose: To examine whether youth and young adult e-cigarette use is associated with initiation of cigars, little cigars, or cigarillos (CLCCs) and current use of flavored CLCCs.

Basic Procedures: The sample is drawn from the Truth Longitudinal Cohort, a probability-based longitudinal cohort of youth and young adults recruited at ages 15-21 and surveyed every six months. The sample for this study was CLCC-naïve defined as those who had never used CLCCs as of 2017 (N = 5586).

E-Cigarette Use Among Youths and Young Adults During the COVID-19 Pandemic: United States, 2020.

To determine whether the COVID-19 pandemic affected e-cigarette use among young people in the United States. Data came from a weekly cross-sectional online survey of youths and young adults (aged 15-24 years). Logistic regression analyses measured odds of past-30-day e-cigarette use (n = 5752) following widespread stay-at-home directives (March 14-June 29, 2020), compared with the pre‒COVID-19 period (January 1-March 13, 2020).

Youth and young adult risk perceptions and behaviours in response to an outbreak of e-cigarette/vaping-associated lung injury (EVALI) in the USA.

Objective: To determine whether awareness of emerging vaping-attributable health conditions influences vaping-related risk perceptions and behaviours among young people.

Design: Respondents aged 15-24 years (n=3536) were drawn from a repeated cross-sectional online panel survey (222 participants/week) during an e-cigarette/vaping-associated lung injury (EVALI) outbreak in the USA (September 2019-January 2020). Logistic regression models tested for associations between EVALI awareness and perceived lung injury risk and product harm, stratified by e-cigarette/vape use and controlling for awareness of other e-cigarette/vaping news stories, demographic characteristics and outbreak week.

Effects of Multiple Exposures and Ad-Skipping Behavior on Recall of Health Messages on YouTube.

Although measuring exposure to public health messages is key to understanding campaign effectiveness, little is known about how exposure to and avoidance of digital ad messages may influence self-reported ad recall. A sample of 15-24-year-olds ( = 297) received a varying number of forced-view and skippable test ads across multiple simulated YouTube sessions. Each session was coded for whether the participant viewed the ad or skipped it.

Early Evidence of an Opioid Education Campaign: A Case Study of Rhode Island.

Context: The opioid crisis poses a significant burden at a national level, and certain states have seen particularly high rates of misuse, addiction, and overdose. In 2017, Rhode Island reported opioid-related deaths nearly twice the national average.

Objective: To test message efficacy and evaluate the effectiveness of campaign messaging to shift attitudes/beliefs related to opioid misuse in Rhode Island.
