The Influence of Friends on Teen Vaping: A Mixed-Methods Approach.

Vaping is popular among adolescents. Previous research has explored sources of information and influence on youth vaping, including marketing, ads, family, peers, social media, and the internet. This research endeavors to expand understanding of peer influence.

Associations between tobacco use patterns and demographic characteristics of sexual minority and heterosexual youth: Results from a nationwide online survey.

Introduction: Youth are at risk for tobacco use, and previous research has pointed to increased vulnerabilities associated with sexual minority identity. For example, LGB youth have increased odds for using tobacco than their heterosexual peers, and bisexual youth have higher odds of smoking than other sexual identity groups. As new tobacco products proliferate and health risks from dual/poly use grow, increased understanding of tobacco use patterns by sexual minority youth is needed.

Perceptions of electronic cigarettes among ethno-culturally diverse Latino adults in four US urban centers.

Objective: The aim of this study was to examine perceptions including knowledge, attitudes, and beliefs about e-cigarettes among ethno-culturally diverse Latino adults living in the US, a rapidly growing minority group for which we know little about their e-cigarette perceptions.

Design: A total of 25 focus groups with Latinos ( = 180; ages 18-64 years) were conducted in 2014. E-cigarettes users and non-users were recruited via purposive sampling techniques.

Cigarette smoking, ENDS use and dual use among a national sample of lesbians, gays and bisexuals.

Introduction: Historically, lesbian, gay and bisexual (LGB) individuals have higher rates of cigarette smoking, often attributed to targeted tobacco advertising, exposure to stressors, and psychological distress. Elevated use of electronic nicotine delivery systems (ENDS) among LGB individuals has been documented recently. However, the LGB groups are not homogeneous and differences may exist between the use of tobacco by men and women within the LGB groups.

Correlates of youth vaping flavor preferences.

Among youth who use electronic nicotine delivery systems (ENDS), e-cigarettes are often the first tobacco product tried. Flavor is a common reason for experimentation with e-cigarettes. This study assessed flavor preferences and the choice of ENDS as an initial product among youth by selected demographic characteristics.

Socioeconomic and Demographic Status and Perceived Health Risks of E-Cigarette Product Contents Among Youth: Results From a National Survey.

The prevalence of e-cigarette use among youth is rising and may be associated with perceptions of health risks for these products. We examined how demographic factors and socioeconomic status (SES) are correlated with the perceived health risks of e-cigarette product contents among youth. .

The role of flavors in vaping initiation and satisfaction among U.S. adults.

Background: The prevalence of electronic cigarette use has grown over the past decade, with some users reportedly initiating e-cigarette use primarily due to flavors. This study examined the role of flavors in initiation among adult e-cigarette users, as well as the association of flavors with satisfaction and perceived addiction to vaping.

Methods: The analysis sample consisted of 1492 current e-cigarette users aged 18 or older, drawn from an online quantitative survey conducted in 2016.

Age differences in electronic nicotine delivery systems (ENDS) usage motivations and behaviors, perceived health benefit, and intention to quit.

Introduction: Data from comprehensive studies are sparse regarding age differences in issues related to electronic nicotine delivery systems (ENDS) usage. This study examined age differences in usage motivations and behaviors, perceived health benefit, and quit intentions in a large and diverse sample recruited online.

Methods: The sample included 1,432 current ENDS users, ages 18-64, drawn from a national online survey conducted in 2016.

Perceived health risks of electronic nicotine delivery systems (ENDS) users: The role of cigarette smoking status.

Introduction: Use of electronic nicotine delivery systems (ENDS) has increased markedly. We examined how current ENDS users differ in perceptions of tobacco and ENDS-related health risks as a function of cigarette smoking status.

Methods: We classified 1329 current ENDS users completing a national online survey based on cigarette smoking status, and employed linear and logistic regression to assess group differences in perceptions of tobacco-related health risks.
