RESUMO
INTRODUCTION: Tobacco companies have devoted increased resources in recent years to developing and marketing heated tobacco products (HTPs) as alternatives to combustible products like cigarettes. However, little is known about correlates of awareness and use of these products in American young adults. METHODS: Two thousand four hundred ninety-seven young adults (mean age = 21.6) completed survey items on HTP awareness and lifetime use in 2018-2019. Logistic regression models compared young adults who were (1) unaware of HTPs (reference group) with those who were, (2) aware of HTPs, and (3) had ever used HTPs on demographic, tobacco, and other substance use characteristics. Among current smokers, these groups were compared on cigarette use, dependence, and readiness to quit. RESULTS: Approximately 12% of respondents (n = 293) were aware of HTPs, and 5% (n = 134) reported lifetime HTP use. Controlling for demographics, HTP awareness and use were both associated with greater use of all types of tobacco products, number of different tobacco products, and use of marijuana and other drugs. Among current smokers, HTP awareness and use correlated with heavier cigarette consumption, greater dependence, and past-month marijuana use, but not with recent quit attempts or thinking about quitting cigarettes. CONCLUSIONS: Awareness and use of HTPs among young adults were associated with greater use of tobacco products and other substances and, among current smokers, with greater cigarette dependence (but not cessation-related factors). As these products become increasingly available in the United States, additional surveillance and monitoring activities are needed to better understand use patterns, consequences, and reasons for using HTPs. IMPLICATIONS: Few studies have examined factors associated with awareness and use of heated tobacco products (HTPs) among US young adults. HTP awareness and lifetime use correlated with a range of factors, including male gender, white race/ethnicity, and tobacco and other substance use. Lifetime use of HTPs was low (5%); most lifetime HTP users reported history of other tobacco use, but a sizeable minority (14%) reported no other tobacco product use history. Among current cigarette smokers, cigarette dependence, poly-tobacco use, and marijuana use-but not cigarette cessation attempts or contemplation-were associated with greater likelihood of awareness and use of HTPs.

BACKGROUND: Longitudinal studies report associations between use of electronic cigarettes (ECs) and cigarettes over time among young people, but do not distinguish within- from between-person effects, which complicates interpretation of findings. Further, the role of shared risk factors, such as substance use and mental health, in explaining longitudinal associations between EC and cigarette use remains unclear. This study used within- and between-person analyses to assess longitudinal associations between youths' EC and cigarette use and shared risk factors. METHODS: Between 2015 and 2017, 2039 youths completed three Web-based surveys, allowing us to model EC and cigarette use from ages 16 to 20. Auto-regressive latent growth models with structured residuals (ALT-SR) examined both between-person and within-person associations between past-month frequency of EC use, cigarette use, and third variables (alcohol and marijuana use, mental health symptoms) over time. RESULTS: Models revealed robust reciprocal associations between EC and cigarette use, such that more frequent EC use at one time predicted more frequent cigarette use at the subsequent time, and vice versa. Between-person analyses showed associations between shared risk factors and both EC and cigarette use. However, shared risk factors did not predict frequency of subsequent EC and cigarette use in within-person analyses. CONCLUSIONS: Findings add to a growing body of research suggesting that EC use among youth is prospectively associated with progression toward greater cigarette use. Shared risk factors may help explain differences in EC and cigarette use patterns between young people, but do not appear to influence longitudinal trajectories of EC and cigarette use within individuals. IMPLICATIONS: This study examined within- and between-person associations between e-cigarette use, cigarette use, and shared risk factors (alcohol use, marijuana use, mental health symptoms) in a longitudinal cohort of youths. Within- and between-person analyses revealed reciprocal prospective associations between e-cigarette and cigarette use, suggesting a progression toward more frequent use of both products over time. The shared risk factors examined here did not affect escalations in e-cigarette or cigarette use over time within individuals, but likely influence which youths use these products. Findings add to a growing body of evidence suggesting that e-cigarette use increases subsequent cigarette use in young people.

OBJECTIVE: To examine the relationship between college students' familiarity with and involvement in Active Minds, a student peer organization focused on increasing mental health awareness, decreasing stigma, and affecting mental health knowledge, attitudes, and behaviors. METHOD: Students (N = 1,129) across 12 California colleges completed three waves of a web-based survey during the 2016-2017 academic year to assess familiarity with and involvement in Active Minds and mental health attitudes, behaviors, and perceived knowledge. Fixed-effects models assessed relations between changes in organization familiarity and involvement and changes in mental health-related outcomes over time overall and stratified by students' baseline engagement (ie, familiarity/involvement) with Active Minds. RESULTS: Overall, increased familiarity with Active Minds was associated with increases in perceived knowledge (0.40; p < .001) and decreases in stigma over time (-0.33; p < .001). Increased involvement was associated with increases in perceived knowledge (0.40; p < .001) and a range of helping behaviors. Associations differed by students' baseline engagement with Active Minds. For students with low engagement, increased familiarity with Active Minds was associated with decreased stigma and improved perceived knowledge. For students with moderate baseline engagement, increasing involvement with Active Minds was associated with increases in helping behaviors (eg, providing emotional support, connecting others to services) over time. CONCLUSION: Student peer organizations' activities can improve college student mental health attitudes and perceived knowledge and significantly increase helping behaviors. Such organizations can complement more traditional programs and play an important role in improving the campus climate with respect to mental health.
