Prevalence and correlates of past 30-day dual-vaping of nicotine and cannabis among adolescents in five New England states.

Significance: Adolescent vaping behavior includes vaping of multiple substances, including both nicotine and cannabis (dual-vaping). This study describes the prevalence and the sociodemographic correlates of past 30-day dual-vaping.

Methods: We recruited adolescents ages 13-17 from five New England states (Massachusetts, Connecticut, Rhode Island, Vermont, New Hampshire) through the Prodege online survey panel from April 2021 to August 2022.

Effects of brief exposure to misinformation about e-cigarette harms on Twitter on knowledge and perceptions of e-cigarettes.

Background: This study examined whether exposure to misinformation found on Twitter about e-cigarette harms leads to inaccurate knowledge and misperceptions of harms of e-cigarette use among cigarette smokers.

Methods: We conducted an online randomized controlled experiment in November 2019 among an online sample of 2400 adult US and UK cigarette smokers who did not currently use e-cigarettes. Participants viewed four tweets in one of four conditions: 1) e-cigarettes are as or more harmful than smoking, 2) e-cigarettes are completely harmless, 3) e-cigarette harms are uncertain and 4) control (physical activity).

Smoking Protective and Risk Factors Among Transgender and Gender-Expansive Individuals (Project SPRING): Qualitative Study Using Digital Photovoice.

Background: Transgender and gender-expansive (TGE) adults are twice as likely to smoke cigarettes than cisgender individuals. There is a critical gap in research on effective and culturally sensitive approaches to reduce smoking prevalence among TGE adults.

Objective: This study aims to qualitatively examine the risk and protective factors of cigarette smoking among TGE adults through real-world exemplars.

Gendered Conceptions of Preconception Health: A Thematic Analysis of Men's and Women's Beliefs about Responsibility for Preconception Health Behavior.

Preconception health (PCH) focuses on taking steps before a pregnancy to safeguard the health of the woman and future baby. Although recommendations to improve PCH target all people of reproductive age, research shows most interventions and messages focus primarily on women, which may contribute to existing normative beliefs that women are more responsible for protecting children's health. In this study, we explore society's gendered expectations of responsibility for engaging in recommended PCH behaviors (i.

The Use of Substances Other Than Nicotine in Electronic Cigarettes Among College Students.

Introduction: Electronic cigarettes (e-cigarettes) have grown in popularity, especially among youth and young adults. Although e-cigarettes were originally intended to vaporize a liquid mixture containing nicotine, there appears to be an increasing trend in other substance use in e-cigarettes (OSUE).

Materials And Methods: Cross-sectional data from 1542 undergraduate college student e-cigarette users from a large Midwestern university were collected via online survey to assess prevalence of e-cigarette use, reasons for use, perceived harm, and prevalence and predictors of OSUE.

Measuring Exposure to Direct-to-Consumer Advertising-A Validation Study in the Context of Cancer-Related Treatment Advertising.

This research examines two recurrent conceptual issues of measuring media exposure in survey research in the context of cancer-related direct-to-consumer advertising (CR-DTCA)-the level of content specificity of survey items and the benefits of providing exemplars to aid recall. We evaluated three candidate measures of cancer patients' self-reported exposure to CR-DTCA; these measures varied in content specificity and provision of ad exemplars. Using data from two distinct population-based surveys, we assessed the performance of each measure based on several reliability and validity criteria.
