Exploring non-smokers’ attitudes toward e-smoking: results from the Minerva Project Europe

Abstract Background In the shifting paradigm of tobacco use, the attitudes of non-smokers toward e-cigarettes are crucial for public health planning, as in the literature it has been suggested that non-smokers who use e-cigarettes could be more prone to switch to tobacco. This multi-center study investigates the interplay between traditional smoking and the potential benefits of transitioning to e-smoking, through a comprehensive examination of smoking behaviors, dietary, and lifestyle practices. Methods MINERVA (My changINg lifEstyles, our Research, and eVeryone’s heAlth) is an ongoing prospective international cohort study aimed at investigating the association between smoking habits and dietary and lifestyle habits among the study participants. The secondary objective pertains to the assessment of subjects’ willingness to try e-cigarettes. We implemented an univariable logistic regression analysis on a dataset comprising 2367 nonsmokers to identify factors influencing their willingness to smoke e-cigarettes. Results Employment significantly predicted willingness, with employed non-smokers showing a higher likelihood to consider e-smoking (OR 2.5, p = 0.002). Household dynamics, specifically the presence of children, also affected the decision, indicating a protective effect against adopting e-smoking (OR 1.26, p < 0.001). Lifestyle choices, particularly fitness and dietary habits, played a discernible role. Surprisingly, age inversely correlated with the willingness to try e-smoking, as younger non-smokers were more likely to consider it (OR 0.97 per year increase, p < 0.001), suggesting that this openness could increase their risk of future tobacco use, which carries important public health consequences. Conclusions The study’s outcomes underscore the impact of socio-economic and lifestyle factors on non-smokers’ openness to e-cigarettes. These insights are pivotal for devising culturally competent educational campaigns and regulatory policies. Key messages • In the shifting paradigm of tobacco use, the attitudes of non-smokers toward e-cigarettes are crucial for public health planning. • By thoroughly analyzing smoking habits, diet, and lifestyle choices, the Minerva Project research aims to shed light on the complex dynamics between health behaviors and smoking.

Role of Impulsivity in Explaining Social Gradient in Youth Tobacco Use Initiation: Does Race Matter?

Socioeconomic status (SES) is traditionally viewed as a protective factor against impulsivity and subsequent tobacco use in youth. The prevailing model suggests that higher SES is associated with lower impulsivity, which in turn reduces the likelihood of future tobacco use. However, this pathway may not hold uniformly across racial groups due to differences in impulsivity and the phenomenon of Minorities' Diminished Returns (MDRs), where the protective effects of SES, such as educational attainment, tend to be weaker or even reversed for Black youth compared to their White counterparts. This study aims to examine the racial heterogeneity in the pathway from childhood SES to impulsivity and subsequent tobacco use initiation during adolescence, focusing on differences between Black and White youth. Data were drawn from the Adolescent Brain Cognitive Development (ABCD) Study, which includes a diverse sample of youth aged 9 to 16 years. The analysis examined the relationship between baseline family SES (age 9), impulsivity (age 9), and subsequent tobacco use (ages 9 to 16). Impulsivity was measured using the Urgency, Premeditation (lack of), Perseverance (lack of), Sensation Seeking, and Positive Urgency Impulsive Behavior Scale (UPPS-P). Structural equation modeling (SEM) was employed, with analyses stratified by race to explore potential differences in these associations. Overall, 6,161 non-Latino White and 1,775 non-Latino Black adolescents entered our analysis. In the full sample, higher family SES was linked to lower childhood impulsivity and, consequently, less tobacco uses in adolescence. However, racial differences emerged upon stratification. Among White youth, higher SES was associated with lower impulsivity, leading to reduced tobacco use, consistent with the expected model. In contrast, among Black youth, higher SES was not associated with lower impulsivity, thereby disrupting the protective effect of SES on tobacco use through this pathway. These findings suggest that racial heterogeneity exists in the SES-impulsivity-tobacco use pathway, aligning with the MDRs framework, which highlights how structural factors may weaken the protective effects of high SES among Black youth. These findings underscore the importance of considering racial heterogeneity in the relationships between SES, impulsivity, and tobacco use. The observed disparities suggest a need for targeted interventions that address the unique challenges faced by Black youth, who may not experience the same protective benefits of high SES as their White peers. These results carry significant implications for public health strategies aimed at reducing tobacco use in racially diverse populations.

Disentangling the effects of self-control and the use of tobacco and cannabis on violence perpetration from childhood to early adulthood.

Associations among self-control, substance use (e.g., tobacco and cannabis use), and violence perpetration have been documented during the adolescent years, but the direction of these associations is not well understood. Using five assessments (covering 9 years) from a prospective-longitudinal study, we examined self-control as a precursor and subsequent mechanism of associations between adolescent substance use and physical violence perpetration. Data came from a large, ethnically diverse sample (n = 1,056). Youth reported their self-control at ages 11, 13, 15, 17, and 20; and their tobacco and cannabis use, and physical violence perpetration at ages 13, 15, 17, and 20. Cross-lagged panel analyses examined associations between these constructs over time. More self-control in late childhood and early adolescence was associated with less future tobacco and cannabis use and physical violence perpetration. Tobacco use was partially associated with more physical violence over time; these associations were not mediated by self-control. Tobacco use in early adolescence was associated with future cannabis use; during late adolescence, tobacco and cannabis use were reciprocally associated over time. Cannabis use was not associated with future physical violence perpetration. Early adolescent self-control plays an important role in later substance use and violence perpetration, and tobacco use has unique links with both later cannabis use and violence perpetration. Supporting the capacities for self-control in late childhood and early adolescence and preventing the initiation and use of entry-level substances could play an important role in preventing both substance use and violence perpetration and their many costs to society.

Tobacco Susceptibility Explains Diminished Returns of Family Income on Black Adolescents' Tobacco Initiation.

Minorities' Diminished Returns (MDRs) theory posits that socioeconomic resources have weaker protective effects on health and behavior for racial and ethnic minorities compared to Whites. This study examines whether tobacco susceptibility, defined as curiosity, intention, and openness to future tobacco use, mediates the diminished returns of family income on tobacco initiation among Black adolescents. Data from the Adolescent Brain Cognitive Development (ABCD) Study were analyzed. Participants were followed from age 9 to 16. All participants were tobacco naive at baseline. Tobacco susceptibility was assessed through self-reported measures of curiosity, intention, and openness to future tobacco use. Structural equation modeling (SEM) was used to examine the relationship between family income, tobacco susceptibility, and tobacco initiation. Overall, 10,653 Black or White youth entered our analysis. The analysis revealed that higher family income was less effective in preventing tobacco initiation among Black adolescents. Tobacco susceptibility significantly predicted tobacco initiation and partially mediated the relationship between family income and tobacco initiation. Tobacco susceptibility explains some of the diminished returns of family income on tobacco initiation among Black adolescents. Interventions aimed at reducing tobacco susceptibility may enhance the protective effects of family income and help mitigate health disparities.

Association between nucleus accumbens volume and future tobacco and Marijuana use in early adolescence

IntroductionNucleus accumbens (NAc), a crucial component of the brain's reward network, plays a role in reward-related behaviors like substance use. However, limited knowledge exists about sex differences in the predictive power of NAc volume for the initiation of tobacco and marijuana use among children transitioning into early and middle adolescence. Our aim was to compare the predictive utility of NAc volume for adolescents' initiation of tobacco and marijuana use over a three-year period. MethodsData from the Adolescent Brain Cognitive Development study (ABCD), a longitudinal study of pre-adolescents aged 9–10 years, were utilized. The study included 9–10 pre-adolescents (n = 11,795) who were followed for 36 months. Cox regression was employed to examine whether NAc volume predicts subsequent initiation of tobacco and marijuana during the follow-up period. Covariates included age, race/ethnicity, puberty, parental composition, parental education, and area-level median income. Sex was the moderator. ResultsWhile NAc volume predicted future substance use, this association varied based on substance type (tobacco vs. marijuana), sex (male vs. female), and laterality (brain hemisphere). A larger right NAc volume (mm^3) inversely associated with subsequent tobacco use initiation for female youth (HR = 0.998; 95% CI: 0.996–1.000), while it showed no association for male youth (p = 0.385). Larger left NAc volume (mm^3) did not associate with subsequent tobacco use initiation for female youth (p = 0.108) but showed a positive association for male youth (HR = 1.002; 95% CI: 1.001–1.003). NAc volume did not show an association with subsequent marijuana use initiation for either sex. ConclusionsThe predictive impact of right and left NAc volumes on future tobacco or marijuana use may differ for male and female adolescents, suggesting that the salience of NAcc in regulating the reward system is influenced by sex, substance type, and brain hemisphere.

Sex Differences in the Relationship Between Nucleus Accumbens Volume and Youth Tobacco or Marijuana Use Following Stressful Life Events.

Exposure to stressful life events (SLEs) can upset balance and affect the healthy brain development of children and youths. These events may influence substance use by altering brain reward systems, especially the nucleus accumbens (NAc), which plays a key role in motivated behaviors and reward processing. The interaction between sensitization to SLEs, depression, and substance use might vary between male and female youths, potentially due to differences in how each sex responds to SLEs. This study aims to examine the effect of sex on the relationship between SLEs, Nucleus Accumbens activity, and substance use in a nationwide sample of young individuals. We utilized data from the Adolescent Brain Cognitive Development study (ABCD), a longitudinal study of pre-adolescents aged 9-10 years, comprising 11,795 participants tracked over 36 months. Structured interviews measuring SLEs were conducted using the Kiddie Schedule for Affective Disorders and Schizophrenia (K-SADS). Initial linear regression analyses explored if SLEs could predict volumes of the right and left NAc. Subsequently, Cox regression models were used to investigate how SLEs and NAc volume might predict the initiation of tobacco and marijuana use, with the analysis stratified by sex to address potential sex differences. Our findings reveal that SLEs significantly predicted marijuana use in males but not in females, and tobacco use was influenced by SLEs in both sexes. A higher number of SLEs was linked with decreased left NAc volume in males, a trend not seen in females. The right NAc volume did not predict substance use in either sex. However, volumes of both the right and left NAc were significant predictors of future tobacco use, with varying relationships across sexes. In females, an inverse relationship was observed between both NAc volumes and the risk of tobacco use. In contrast, a positive correlation existed between the left NAc volume and tobacco and marijuana use in males, with no such relationship for females. This study underscores that the associations between SLEs, NAc volume, and subsequent substance use are influenced by a nuanced interplay of sex, brain hemisphere, and substance type.

Noncigarette Tobacco Product Use Among Smoking-Susceptible and Nonsusceptible Adolescent Never Smokers, 2009–2021

PurposeExamine trends in noncigarette tobacco use among smoking susceptible and nonsusceptible adolescents from 2009–2021. MethodsData came from cross-sectional samples of the National Youth Tobacco Survey (N = 183,198). Using Pierce's smoking susceptibility scale, participants were classified as either susceptible or nonsusceptible to cigarette smoking. Their use of noncigarette tobacco products was classified into four mutually exclusive categories: nonuse, noncigarette combustibles use, noncombustibles use, and noncigarette combustibles and noncombustibles dual use. We produced covariate-adjusted predicted marginal proportions of noncigarette tobacco use for 12 National Youth Tobacco Survey years, which were entered into Joinpoint trend analysis software to determine (a) trends in noncigarette tobacco use from 2009–2021 using the average annual percent changes (AAPCs) and (b) changes in each time segment using the average percent change. Models were fitted by smoking susceptibility, sex, and race/ethnicity. ResultsNonuse was lower among susceptible (vs. nonsusceptible) adolescents whereas noncigarette tobacco use was higher. Trends show significant declines in nonuse (nonsusceptible: AAPC = −0.3%) and noncigarette combustibles use (susceptible: AAPC = −12%) between 2009–2021, increases in noncombustibles use (susceptible: AAPC = 18%, nonsusceptible: AAPC = 19%) between 2009 and 2019, and steadiness in dual use. Parallel trends were observed when stratified by sex and race/ethnicity with notable increases in noncombustibles use among females and Latinos. DiscussionNoncigarette tobacco use differed by smoking susceptibility. Observed trends, especially when stratified by sex and race/ethnicity, raise concerns about tobacco use disparities among females and Latinos. Smoking susceptibility can help identify at-risk adolescents for current or future tobacco use.

Improving Prediction of Tobacco Use Over Time: Findings from Waves 1-4 of the Population Assessment of Tobacco and Health Study.

First-order Markov models assume future tobacco use behavior is dependent on current tobacco use and are often used to characterize patterns of tobacco use over time. Higher-order Markov models that assume future behavior is dependent on current and prior tobacco use may better estimate patterns of tobacco use. This study compared Markov models of different orders to examine whether incorporating information about tobacco use history improves model estimation of tobacco use and estimated tobacco use transition probabilities. We used data from four waves of the Population Assessment of Tobacco and Health Study. In each Wave, a participant was categorized into one of the following tobacco use states: never smoker, former smoker, menthol cigarette smoker, non-menthol cigarette smoker, or e-cigarette/dual user. We compared first-, second-, and third-order Markov models using multinomial logistic regression and estimated transition probabilities between tobacco use states. The third-order model was the best fit for the data. The percentage of former smokers, menthol cigarette smokers, non-menthol cigarette smokers, and e-cigarette/dual users in Wave 3 that remained in the same tobacco use state in Wave 4 ranged from 63.4% to 97.2%, 29.2% to 89.8%, 34.8% to 89.7%, and 20.5% to 80.0%, respectively, dependent on tobacco use history. Individuals who were current tobacco users, but former smokers in the prior two years, were most likely to quit. Transition probabilities between tobacco use states varied widely depending on tobacco use history. Higher-order Markov models improve estimation of tobacco use over time and can inform understanding of trajectories of tobacco use behavior. Findings from this study suggest that transition probabilities between tobacco use states vary widely depending on tobacco use history. Tobacco product users (cigarette or e-cigarette/dual users) who were in the same tobacco use state in the prior two years were least likely to quit. Individuals who were current tobacco users, but former smokers in the prior two years, were most likely to quit. Quitting smoking for at least two years is an important milestone in the process of cessation.

Prevalence, Trends, and Harm Perception Associated with E-Cigarettes and Vaping among Adolescents in Saudi Arabia

Younger generations are an important market for the tobacco products industry since most smokers try their first cigarette before the age of 18. Electronic cigarettes (e-cigarettes) are a common mode of smoking among teens, and the number of users is increasing exponentially. This study aimed to estimate the current prevalence of e-cigarettes and vaping usage among adolescents between the ages of 15 and 19 in the city of Mecca, Saudi Arabia. This study was conducted among 534 students at four high schools. They were asked to complete a 23-item questionnaire retrieved from the Global Youth Tobacco Survey. Descriptive statistics and regression analysis were conducted. The study was approved by the Ministry of Health Saudi Arabia Medical Research Center Institutional Review Board committee on October 10, 2018 (research number 18-506E). A total of 109 (20.6%) of the participants reported being smokers of e-cigarettes. Being a male (OR = 1.55; 95% CI: [1.01-2.37]), in the second year of high school (OR = 2.91; 95% CI: [1.61-5.24], ever experimenting with regular tobacco cigarettes, being a current shisha smoker, living with a smoker, and believing that e-cigarettes are less addictive than traditional cigarettes are all factors independently associated with e-cigarette use in this sample of adolescents. Among adolescent smokers, even minimal experience with smoking is correlated with pro-smoking attitudes. E-cigarette use is common in adolescents and related to the use of other combustible tobacco products. Tobacco control efforts at all levels should eliminate factors fostering future tobacco use to minimize the burden of disease and disability in vulnerable populations.

Study on epidemiological status of e-cigarette use among adolescent in Zhejiang province, China

Objective: To describe the prevalence of e-cigarette use among adolescent in Zhejiang province, and to analyze its distribution of different genders and school types to provide evidence for controlling the use of e-cigarette among adolescent. Methods: A total of 7 663 students from 60 middle schools through stratified multi-stage cluster sampling methods from Zhejiang province were surveyed by using questionnaire. Indicators as tried to use e-cigarette rate, current e-cigarette using rate, and other indicators were collected. All data were weighted by age proportions of adolescent in Zhejiang. Results: The prevalence of tried to use and current using e-cigarettes among middle school students were 6.99% and 1.45%, respectively; and there were 4.19% juniors who were susceptibility to future e-cigarette use. The rate of tied to use e-cigarette, current using e-cigarette and susceptibility to future e-cigarette use were higher in boys than in girls. The rate of current using e-cigarette was 2.07% for rural and 0.48% for urban. Technical secondary school students had the highest rate of tried to use e-cigarette and susceptibility to future e-cigarette use (13.53%, 6.91%). Junior school students (2.96%) had the lowest level of susceptibility to future tobacco use. The rate of tried e-cigarette use and current e-cigarette use and susceptibility to future e-cigarette use were higher in the group of "One of students' parents was smoker" (8.63%, 2.19%, 5.23%). The highest rate of current smoking was found in the group of "Weekly allowance more than 50 Yuan" (10.02%, 2.54%, 6.29%). Compared to technical secondary school students, senior school student (OR=0.57) and junior school students (OR=0.45) were less likely to try to use e-cigarette. Students whose weekly allowance were less than 20 Yuan were less likely to try to use e-cigarette (OR=0.49). Students who were boys (OR=5.44) and one of their parents was smoker (OR=1.59) were more likely to try to use e-cigarette. Conclusions: There were middle school students with tried e-cigarette use and current e-cigarette use, especially in technical secondary schools. The prevalence of e-cigarette using among middle school students increased with age. It is important to further spread of e-cigarette knowledge widely and deeply, and reduce the susceptible population of adolescents using e-cigarettes.

Alcohol and tobacco consumption among Australian sexual minority women: Patterns of use and service engagement.

Sexual minority women consume both alcohol and tobacco at higher rates than heterosexual women. However, various sociodemographic and cultural factors associated with these practices among sexual minority women in Australia are not well understood, nor are the factors associated with seeking alcohol-related support. This study utilised data from cisgender sexual minority women respondents of Private Lives 3: a national, online, cross-sectional survey of the health and wellbeing of LGBTIQ adults in Australia aged 18+ conducted in 2019. Multivariable analyses were performed to identify co-existing smoking and alcohol use, sociodemographic factors associated with smoking, alcohol consumption and seeking alcohol-related support. Of 2,647 sexual minority women respondents, 16.90% were currently smoking tobacco, 7.67% smoking tobacco daily and 60.50% reported potentially risky patterns of alcohol consumption. Tobacco and potentially risky alcohol consumption were found to frequently co-occur. Women who identified as queer were more likely than lesbian identifying women to currently smoke tobacco and to smoke tobacco daily. Tobacco consumption was associated with increased age, unemployment, low-mid range income and secondary-school education, while potential risky drinking was associated with living in outer urban or rural areas and being Australian born . Self-reporting having struggled with alcohol in the past twelve months was associated with residential location. Less than 3% of the sample has sought help for alcohol use. Seeking support was more likely as women aged, and with potentially risky drinking, and much more likely with self-perceived struggles with alcohol. The findings highlight the need for future alcohol and tobacco use health promotion strategies focussing on sexual minority women to attend to within group differences that relate to risk of higher consumption. They also highlight the need for approaches that empower sexual minority women to self-identify when they are struggling with alcohol use and encourage seeking support with organisations that are affirming of sexual minority women.

The role of self-discontentment and impulsivity for youth smoking behavior, nicotine dependence and future smoking intention in a clinical sample of Turkish adolescents.

Smoking is one of the most important public health problems among young people. Potential risk factors that may cause vulnerability to smoke in youth should be well known and investigated. The aim of the present study was to evaluate the associations of current smoking behavior and future smoking intention with high-risk personality traits for substance abuse in a clinical sample of Turkish adolescents, and also evaluate nicotine dependence and smoking characteristics with the personality traits in a subsample of regular smokers. A cross-sectional study was adopted in which 196 participants took part (aged 14-18 years with a mean of 16.7 years). The assessment consisted of a sociodemographic questionnaire that also questions current smoking behavior and future smoking intention; and additionally, two self-administered instruments including the Substance Use Risk Profile Scale (SURPS) for all participants, and Fagerström Test for Nicotine Dependence (FTND) for only regular smokers. Regular smokers scored higher than never smokers on the lack of self-contentment subscale of SURPS (F(2)=3.30, p=.039). Future smoking intention was found to be associated with nicotine dependence (F(3)=6.67, p=.001). Regular smokers with high levels of nicotine dependence had higher levels of impulsivity and smoked more cigarettes per day than those with low levels of nicotine dependence (t=2.489, p=.017; and t=3.530, p=.001, respectively). The structural equation models (SEM) were created based on these results and the personality theory for substance abuse. The SEM results showed that the first evidence that lack of selfcontentment positively influences regularly smoking behavior and impulsivity positively influences future smoking intention through nicotine dependence. Lack of self-contentment and impulsivity may mediate the transition from current smoking behavior to future tobacco use disorders in Turkish adolescents. The assessment and intervention of selfdiscontentment and impulsivity can be beneficial in reducing the current smoking behavior in Turkish adolescents.

Smoking by pregnant mothers and risk of future tobacco use by offspring: a meta-analysis

ABSTRACT Background There are twelve studies indicating an association between prenatal maternal smoking and the increase risk of tobacco use by offspring. Objective To examine the association between maternal smoking during pregnancy and the development of smoking behavior patterns among offspring. This paper is the first to quantify that effect systematically and explore heterogeneity sources related to this issue. Methods A literature search for material published in English and Chinese l was done using databases PubMed, Google Scholar, Web of Knowledge and Microsoft Academic Search to gather peer-reviewed studies that gave the odds ratio for maternal smoking and an offspring’s tobacco habitual use. Results Based on the results from 12 cohort studies published between 1991-2019, offspring whose mothers smoked during pregnancy were at an elevated risk for smoking (RR=1.85, 95% CI: 1.67-2.06, p<0.001, a fixed effects model with Shore correction for between study variance) compared to those children whose mothers did not smoke during pregnancy. There is a dose response between maternal smoking during pregnancy and offspring smoking. The data support a relationship between maternal smoking during pregnancy and an increased risk of offspring smoking later in life. Conclusion The findings of the research suggest that prenatal tobacco exposure may cause an increase in offspring smoking.

Home Tobacco Use Policies and Exposure to Secondhand Tobacco Smoke: Findings from Waves 1 through 4 of the Population Assessment of Tobacco and Health (PATH) Study.

Background: The 2006 Surgeon General’s Report recommended the elimination of smoking in homes as an effective protective measure against the harmful effects of secondhand tobacco smoke exposure. This study aims to examine trends in the prevalence and levels of the adoption of home tobacco use policies specifically for cigarettes, e-cigarettes, smokeless tobacco, and the relationships between home tobacco use policies and self-reported exposure to secondhand tobacco smoke. Methods: This study utilizes data from Wave 1 (2013–2014) through Wave 4 (2016–2018) of the Population Assessment of Tobacco and Health (PATH) Study, a large prospective cohort study of youths and adults in the United States which collected information about both smoke-free and tobacco-free home policies. We present the weighted, population-based, self-reported prevalence of home tobacco use policies overall and by product, and the average number of self-reported hours of secondhand smoke (SHS) exposure by levels of home tobacco policy and by survey wave. In addition, we examine the characteristics of those who adopted (by yes or no) a home tobacco use ban between survey waves. Results: We found a high prevalence of completely tobacco-free home policies (69.5%). However, 10.6% of adults allow the use of any type of tobacco product inside their homes, and 19.8% have a policy allowing the use of some types of tobacco products and banning the use of others. Adults with a complete tobacco use ban inside their homes were more likely to be nonusers of tobacco (79.9%); living with children in the home (71.8%); at or above the poverty level (70.8%); non-white (76.0%); Hispanic (82.7%); and aged 45 or older (71.9%). The adoption of 100% tobacco-free home policies is associated with a 64% decrease in secondhand smoke exposure among youths and a 69% decrease in exposure among adults. Conclusions: Most US adults have implemented tobacco-free home policies; however, there is still exposure to SHS in the home, for both adults and children, particularly in the homes of tobacco users. Additional research should investigate tobacco-free home policies for different types of products and what effect they have on future tobacco use behaviors.

Examining the differential effects of latent impulsivity factors on substance use outcomes in African American men

African Americans have elevated substance use-related problems during adulthood despite initiating use later than individuals of other racial/ethnic backgrounds. The present study first validated the structure of the UPPS-P Impulsive Behavior Scale and then examined impulsivity as a prospective risk factor for future alcohol, cannabis, and tobacco use, as well as generalized substance problems, in African American men. Data were drawn from the African-American Men’s Project, which recruited participants (NWAVE-1 = 504; Mean ageWAVE-1 = 20.7; NWAVE-3 = 379; Mean ageWAVE-3 = 23.6) from rural counties of Georgia. Participants responded to an adapted version of the UPPS-P at Wave 1. Confirmatory factor analyses determined that a 5-factor model of impulsivity and a 3-factor hierarchical model of impulsivity described the data equally well, in comparison to 1-factor, 4-factor, or bifactor models. This supports that the structure of the abbreviated UPPS-P in African Americans is likely consistent with observations in White, Hispanic/Latino, and admixed samples. Notably, all second-order factors of the UPPS-P are not alike in predicting substance use outcomes when examined jointly in African American men. Only Deficits in Conscientiousness, which is a second-order factor comprised of Lack of Premeditation and Lack of Perseverance, affected whether individuals met any criteria for future substance use problems. Our findings provide novel insight into the relationship between impulsivity and substance involvement during emerging adulthood in African American men.

E-cigarette susceptibility among U.S. middle and high school students: National Youth Tobacco Survey Data Trend Analysis, 2014–2018

Youth e-cigarette use has rapidly increased in the last few years. Susceptibility is a validated measure associated with future tobacco use. We examined trends in e-cigarette susceptibility across five years (2014–2018) of the National Youth Tobacco Survey among youth e-cigarette never users. We observed increases in overall e-cigarette susceptibility from 2014 to 2016 and decreases from 2016 to 2018. Generally, sociodemographic variables were not associated with trend effects; however, there was an interaction between linear trends with both race/ethnicity and other tobacco product (OTP) use. The percentage of youth who were susceptible to using e-cigarettes ranged from 32.9% in 2014 to 33.2% in 2018 with a high of 36.7% in 2016. We also examined the prevalence of e-cigarette susceptibility by race/ethnicity, sex, school level, OTP use, and e-cigarette harm perception. E-cigarette susceptibility was associated with race, school level, OTP ever use, and e-cigarette harm perceptions. Hispanic youth, those in high school, and OTP ever users were more likely to be susceptible to e-cigarette use compared to their counterparts across all years. E-cigarette susceptibility was most prevalent among those who perceived e-cigarettes to pose “no harm” in 2014 and “little harm” in 2018 when compared to other item response options in 2014 and 2018, respectively. This study is the first to document trends in e-cigarette susceptibility among youth. Understanding antecedents of e-cigarette use and identifying youth subgroups vulnerable to e-cigarette use is valuable to developing effective prevention efforts.Disclaimer: The findings and conclusions in this publication are those of the authors and do not necessarily represent the official position of the Food and Drug Administration or the Centers for Disease Control and Prevention.

Association of Electronic Nicotine Delivery System Use With Cigarette Smoking Progression or Reduction Among Young Adults

The prevalence of electronic nicotine delivery systems (ENDS) use, including e-cigarettes, among US young adults (YAs) has raised questions about how these products may affect future tobacco and nicotine use among YAs. Given this prevalence and that young adulthood is a critical period for the establishment of tobacco and nicotine use, it is important to consider the association between ENDS use and cigarette smoking specifically in this age group. To examine whether ENDS use frequency or intensity is associated with changes in cigarette smoking among US YA ever smokers during 1 year. This cohort study used 3 waves of data (2013-2014, 2014-2015, and 2015-2016) from the Population Assessment of Tobacco and Health (PATH) Study, an ongoing longitudinal cohort study of adults and youth. Unweighted 1:6 propensity score matching was used to match participants on wave 1 risk factors for ENDS use at wave 2. The changes in smoking between wave 2 and wave 3 were assessed using the matched sample. In total, 1096 ENDS-naive, ever cigarette-smoking YAs (18-24 years of age) at wave 1 who participated in wave 2 and wave 3 and who had complete data in the PATH Study were included in the analyses, which were conducted from August 2018 to October 2019. Never ENDS use (n = 987), any previous 30-day ENDS use (n = 109), 1 to 5 days of ENDS use in the previous 30 days (n = 75), and 6 or more days ENDS use in the previous 30 days at wave 2 (n = 34). The analytic sample was selected using multiple variables based on peer-reviewed literature supporting associations with ENDS use. The main outcomes-changes in cigarette smoking behavior between wave 2 and wave 3-were defined using 2 measures: (1) change in smoking frequency, defined as the number of smoking days in the previous 30 days at wave 3 vs wave 2, and (2) change in smoking intensity, defined as the number smoking days in the previous 30 days multiplied by the mean number of cigarettes consumed on smoking days at wave 3 vs wave 2. The present cohort analyses included 1096 YA ever smokers who were ENDS naive at wave 1. The majority of the sample were women (609 [55.6%]) and White individuals (698 [63.7%]), and the mean (SD) age was 21.4 (1.9) years. In wave 1, 161 YAs (14.7%) were daily smokers in the previous 30 days. After propensity score matching, no statistically significant associations were observed between any definition of wave 2 ENDS use and changes in either the frequency or intensity of smoking at wave 3. In this cohort study of US YA ever smokers, ENDS use was not associated with either decreased or increased cigarette smoking during a 1-year period. However, it is possible that the rapidly evolving marketplace of vaping products may lead to different trajectories of YA cigarette and ENDS use in the future.

Smoking status and racial/ethnic disparities in youth exposure to tobacco advertising

Tobacco advertising exposure increases tobacco use among youth. Data were from a largely racial and ethnic minority sample (60% non-Hispanic (NH) Black/African American) of youth (13–18 years) who were nonsmokers susceptible to future tobacco use (n = 686) or current cigarette smokers (n = 674). Regression models tested associations between tobacco advertisement exposure and smoking status, and determined demographic correlates. Nearly all youth recalled seeing a tobacco advertisement (98%), which was associated with smoking (OR = 1.12; 95% CI = 1.08–1.15). Racial minority youth had higher exposure to tobacco advertising. Policies restricting advertisements for all tobacco products are essential for prevention efforts and may help decrease tobacco-related health disparities.

Multidirectional Pathways of Tobacco and Marijuana Use, Including Comorbid Use, Among Young Adults (Aged 18–25 Years) in Texas: A Six-Wave Cross-Lagged Model

PurposePrevalence of past 30-day tobacco and marijuana use are highest among young adults in the U.S., and comorbid use of these products is common. However, it is unclear whether the use of one product precedes the other—an important consideration, given the new climate surrounding marijuana legalization and the popularity of e-cigarette products. MethodsSix-panel cross-lagged regression models, with 6 months between each panel/wave, were used to model bidirectional paths between past 30-day use and comorbid use of marijuana and tobacco products from 2014 to 2017 among young adults (N = 5,221 college students, aged 18–25 years). ResultsCombustible tobacco use and e-cigarette use were prospectively associated with greater risk of future marijuana use while controlling for the stability of use over time, age, race/ethnicity, and sex. Marijuana use was prospectively associated with greater risk of future combustible tobacco and e-cigarette use. Comorbid use was common, but while the odds of comorbid use decreased with increasing age, odds of tobacco use increased. ConclusionsMore young adults may be consolidating their use than are successfully ceasing their tobacco or marijuana use as they mature through young adulthood. Although we observed decreases in comorbid use of combustible tobacco with marijuana and e-cigarettes with marijuana, we simultaneously observed strong stability in single use of these products over time. Taken together, these results should help structure interventions specific to young adults that target use and comorbid use in early young adulthood to discourage initiation, encourage cessation, and curb subsequent escalation in later young adulthood.

Exposure and engagement with tobacco-related social media and associations with subsequent tobacco use among young adults: A longitudinal analysis

BackgroundThis study examines whether self-reported exposure to cigarette, e-cigarette, cigar, and hookah advertising, and engagement with pro-tobacco and anti-tobacco social media, are associated with past 30-day tobacco use one-year later, among young adults. MethodsData were from two waves of the Marketing and Promotions Across Colleges in Texas study, a multi-wave study of two- and four-year Texas college students (N = 3947; M age = 23.3, SD = 2.3; 64% female; 35% white, 31% Hispanic, 19% Asian, 8% African-American/black, 7% multi-racial/other) from 24 urban-area schools. Multiple logistic regression examined longitudinal associations between recall of exposure and engagement at baseline (wave 6, spring 2017) and tobacco use at one-year follow-up (wave 7, spring 2018), accounting for baseline demographic characteristics and tobacco use. ResultsSelf-reported exposure to and engagement with tobacco-related social media were significantly associated with past 30-day use of e-cigarettes, cigars, and hookah at one-year follow up; engagement was also associated with cigarette use. Controlling for other social media, exposure to any product advertising via Reddit increased risk for e-cigarette use (AOR = 1.92 [95% CI: 1.17–3.14]). Pinterest exposure increased risk for cigar use (2.92 [1.24–6.85]). Snapchat exposure increased risk for hookah use (2.94 [1.70–5.11]). Pro-tobacco engagement increased risk for future use of all products (1.77 [1.29–2.42]). Anti-tobacco engagement increased risk for use of cigars (1.59 [1.12–2.27]) and hookah (1.69 [1.27–2.25]). ConclusionsFindings demonstrate that encountering tobacco-related social media is an important risk factor for future tobacco use among young people. Social media should be a focus of federal regulation, counter-marketing and health communication campaigns, and intervention.
