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. A total of 25 focus groups with Latinos (n = 180; ages 18–64 years) were conducted in 2014. E-cigarettes users and non-users were recruited via purposive sampling techniques. Participants completed brief questionnaires on sociodemographic factors and tobacco use. Focus group discussions were conducted in English and Spanish, audio-recorded, and transcribed. Data were analyzed using thematic analysis procedures. Participants were of diverse Latino backgrounds. Over one-third (35%) reported current cigarette smoking and 8% reported current e-cigarette or hookah use. Nonsmokers reported experimenting with e-cigarettes and hookah during social occasions. Participants' perceptions towards e-cigarettes were generally formed in comparison to conventional cigarettes. Perceived benefits of using e-cigarettes included their utility as a smoking cessation aid, higher social acceptability, and lower harm compared to conventional cigarettes. Negative perceptions of e-cigarettes included lower overall satisfaction compared to conventional cigarettes and high content of toxins. Socio-cultural factors (e.g. gender roles, familismo, and simpatía) also influenced perceptions of e-cigarette of study participants. Overall, Latino adults knew relatively little about the potential health risks associated with e-cigarette use. The limited knowledge about and misinformation of e-cigarettes among this rapidly growing minority group have important public health implications. Findings may inform culturally tailored health communication campaigns, which are much needed among underserved US Latino populations in light of low effectiveness of tobacco control and regulatory efforts.

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. METHODS For 3117 youth, aged 13-18 years, who completed an online questionnaire in 2017 and identified their sexual orientation [minority (e.g. lesbian/gay, bisexual, or pansexual) vs majority (heterosexual)] and gender, we classified current tobacco use into four categories: e-cigarette only, other product only (such as cigarette, cigar, or smokeless tobacco; not an e-cigarette), dual/poly use, and no use. Analyses were conducted separately for male and female participants. Multinomial logistic regression was employed. RESULTS Female sexual minority youth had nearly twofold odds of dual/poly tobacco use (OR=1.95; 95% CI: 1.12-3.40), compared to their heterosexual counterparts. For male youth, sexual minority identification was not significantly associated with dual/poly use. No significant differences were found in sexual minority and heterosexual youth e-cigarette only or other tobacco only use groups. Tobacco use patterns also significantly differed by age, race, place of residence, and parental education level. CONCLUSIONS Study findings reveal greater odds of dual/poly tobacco use for female sexual minority youth. Tailored tobacco prevention and cessation programs or interventions are needed for sexual minority youth most at risk of tobacco use, especially multiple product use. [ABSTRACT FROM AUTHOR]

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. The purpose of this research was to examine cigarette smoking, ENDS use and dual use (cigarettes plus ENDS) among LGB subgroups., Methods: We classified 2087 participants completing a national online survey based on tobacco-use status (i.e. cigarette only, ENDS only, dual use) and sexual orientation. Multinomial logistic regression was employed to assess group differences., Results: After adjusting for demographics and socioeconomic status, bisexual women were 1.85 times (95% CI: 1.19-2.87) more likely to report current dual use, in contrast to cigarette only use, compared to heterosexual women. No significant differences were found between lesbian and heterosexual women, or between gay or bisexual men and their heterosexual counterparts., Conclusions: This study describes significantly greater dual use by bisexual women and is one of the first reports of elevated dual use in this group compared to heterosexual women. These findings suggest that targeted health messages may be needed to raise awareness of risk in specific LGB groups and that future research with these populations is necessary to better understand differences in tobacco perceptions and use., Competing Interests: The authors have each completed and submitted an ICMJE form for disclosure of potential conflicts of interest.
