Prevalence and socio-demographic correlates of multi-modal cannabis use among young adults who currently use cannabis.

Cannabis use is common in young adulthood, yet little is known about the prevalence and patterns of multi-modal (i.e., use of more than one mode) cannabis use. Objective: We aimed to (1) determine the past 30-day prevalence of five modes (smoke, vape, edible, dab, other) of cannabis use, (2) describe the prevalence of multi-modal cannabis use (single vs. dual vs. poly-modal), and (3) identify socio-demographic correlates of multi-modal use among young adults. Method: Participants were 764 22-30-year-olds who currently used cannabis from Wave 9 (Spring 2019) of the Marketing and Promotions Across Colleges in Texas Project. Participants were 25.11 years old on average (SD = 1.81), 63.6% female, 38.7% identified as non-Hispanic white, 30.6% as Hispanic/Latino, 13.0% as Asian and 9.4% as Black, and 8.2% identified with two or more races or another race/ethnicity. Bivariate analyses and a multinomial regression were used to examine study questions. Results: Smoking was the most common mode of cannabis use followed by vaping and then edibles. Nearly 43% of participants reported single-modal cannabis use, 33% reported dual-modal use, and 24% reported poly-modal use. Males and those identifying as non-heterosexual were at a greater risk than their counterparts for using multiple modes of cannabis. Participants identifying as Black were at a reduced risk for poly-modal compared to single-modal use. Conclusion: Multi-modal use is common among young adults who currently use cannabis, indicating a need for universal efforts aimed at all young adults. Tailored interventions aimed toward those at elevated risk for multi-modal use also are needed.

Comparing the number of outdoor sugar-sweetened beverage and caffeinated beverage advertisements near schools by school type and school-level economic advantage.

INTRODUCTION: Sugar-sweetened beverage and caffeinated beverage consumption are associated with a variety of health issues among youth. Food and beverage marketing has been shown to affect youth's preferences, purchases, and consumption of marketed products. Previous research suggests that outdoor food and beverage marketing differs by community demographics, with more advertisements in lower-income communities and near schools. The purpose of this study is to examine the density of sugar-sweetened and caffeinated beverage advertisements near schools by school type (middle vs. high school) and by school-level SES. METHODS: Data are from the Outdoor Measuring and Evaluating the Determinants and Influence of Advertising (MEDIA)study, which documented and described all outdoor food and beverage advertisements near 47 middle and high schools in 2012. Beverage advertisements were categorized as: sugar-sweetened/caffeinated, sugar-sweetened/non-caffeinated, non-sugar-sweetened/caffeinated, or non-sugar-sweetened/non-caffeinated. Schools were categorized by type (middle vs high) and by SES as determined by the percentage of students qualifying for free or reduced-price lunch. Bootstrapped non-parametric Mann-Whitney U tests compared the number of advertisements in each category by school type and school-level SES (higher vs lower). RESULTS: Compared to schools with higher SES, schools with lower SES had significantly more advertisements for sugar-sweetened/non-caffeinated beverages (Medianlow = 28.5 (IQR 17-69), vs Medianhigh = 10.5 (IQR 4-17) (p = 0.002)., sugar-sweetened non-caffeinated (Medianlow = 46 (IQR 16-99) vs Medianhigh = 13.5 (IQR 6-25), p = 0.002), -sugar-sweetened caffeinated (Medianlow = 12 (IQR 8-19) vs Medianhigh = 6 (IQR 2-8), p = 0.000), and non-sugar-sweetened non-caffeinated (Medianlow = 30 (IQR 13-65) vs Medianhigh = 14 (IQR 4-29), p = 0.045).There were no significant differences by school type. CONCLUSION: This study adds to the literature demonstrating pervasive marketing of unhealthy products in lower-income communities. Disproportionate exposure to sugar-sweetened and caffeinated beverage advertisements in lower-income communities may contribute to the disparities in associated health outcomes by economic status.

Most commonly used vaping brands by 18-25 year old young adults in Texas-Spring 2023.

PURPOSE: We aimed to determine (1) the most commonly used brands of electronic vaping products (EVPs) by young adults in Texas during Spring 2023, and (2) if brand preferences differ by sociodemographic characteristics, current cigarette smoking, and current cannabis vaping. METHOD: Participants were 2,491 18-25-year-olds (Mean age = 20.6; 62.9% female; 29.7% sexual gender minority; 35.9% non-Hispanic White, 45.0% Hispanic/Latino, 3.5% non-Hispanic Black, 11.6% non-Hispanic Asian, and 4.0% two or more races or another race/ethnicity) enrolled in 21 Texas colleges during February-March 2023 who used EVPs in the past 30-days. RESULTS: Esco Bar was the most popular EVP brand (32.5%), followed by Elf Bar (19%), Vuse (10.1%), and all other brands were used by < 10% of participants. Nearly 20% of participants reported not having a usual brand. Participants who used Esco Bar, Elf Bar, and Puff Bar were younger (i.e., 18-20 years old), female, and Hispanic/Latino. Vuse, JUUL, and Smok were used by participants who were older (i.e., 21-25 years old), male, non-Hispanic white, used EVPs daily, and currently smoked cigarettes. CONCLUSION: The present study extends prior research by providing contemporary data on young adult EVP brand preferences in Texas during Spring 2023. Many of the brands commonly used by young adults (e.g., Esco Bar, Elf Bar) are not currently authorized for marketing or sale by the Food and Drug Administration. Findings underscore a need for additional enforcement efforts that prohibit the distribution and sale of these products to, in turn, prevent EVP use among young adults.

Longitudinal patterns of cannabis and tobacco co-administration and concurrent use among young adult college students.

INTRODUCTION: Co-use, including concurrent use or co-administration, of cannabis and tobacco is most prevalent in young adulthood and associated with worse health outcomes than use of either substance alone. This study examined latent classes of tobacco and cannabis concurrent use and co-administration, and transitions between classes from 2016 to 2019, among a sample of young adult college students in Texas. METHODS: Participants included 4,448 young adults (64.2% female, 64.7% non-white, mean age = 20.5) in a longitudinal cohort study. Measures included past 30-day use of cigarettes. hookah, cigars, ENDS, cannabis, and cannabis and tobacco co-administration. Latent Markov models were used to estimate latent class membership and transitions between classes from 2016 to 2017 and 2017 to 2019. RESULTS: Four latent classes emerged: non-use (58% of students) characterized by low/no probability of any use; general use (19%) characterized by some level of use of all behaviors; blunt and cannabis use class (13%) characterized by high probabilities of cannabis use and co-administration with blunts; and concurrent and co-administration use (10%) with high probabilities of cigarette, cannabis, blunt, and spliff use. Most students remained in the same latent class from 2016 to 2019. CONCLUSIONS: While most students reported low/no tobacco and cannabis co-use, those who used cannabis and/or tobacco remained in their use classes over the course of the study (2016 to 2019). Public health advocates on college campuses should consider prevention and cessation programs that incorporate the constellation of behaviors related to cannabis and tobacco co-use and educate students about the health consequences of co-use.

Depressive symptoms prospectively increase risk for new onset cigarette and ENDS dependence symptoms.

Little research has examined the new onset of cigarette and Electronic Nicotine Delivery System (ENDS) dependence symptoms among young adults. This study aims to 1) examine new onset cigarette and ENDS dependence symptoms over a 4.5-year period and 2) examine how depressive symptoms impact new onset dependence symptoms among young adults. Participants were drawn from 24 colleges in Texas who were participating in a multi-wave cohort study (2014-2019). The present study included 4536 participants aged 18-25 who did not report cigarette or ENDS dependence symptoms at wave 1 (64.1% female; 65.2% non-white; m age = 20.62 [SD = 1.80] at wave 1). Cox's regression models were employed to determine the hazard of new onset cigarette and ENDS dependence symptoms overall and the impact of depressive symptoms. Models controlled for sociodemographic factors and other tobacco product use. 14.4% of participants reported new onset cigarette dependence symptoms and 14.6% reported new onset ENDS dependence symptoms over the 4.5 years of the study. Depressive symptoms significantly predicted increased risk for new onset cigarette (HR = 1.30, CI = [1.21, 1.39]) and ENDS (HR = 1.20, CI = [1.12, 1.29]) dependence symptoms. Young adults exhibited dependence symptoms for cigarettes and ENDS products at similar rates across the 4.5 years of the study. Elevated depressive symptoms increased risk of new onset cigarette and ENDS dependence symptoms, advancing evidence for the self-medication hypothesis. Tobacco and nicotine prevention and cessation programs and messaging are needed particularly among young adults who experience depressive symptoms.

School-Level Socioeconomic Status and Nutrient Content of Outdoor Food/Beverage Advertisements.

We examined if areas around schools with more students of lower socioeconomic status (SES) have more total food/beverage advertisements and/or more advertisements with poorer nutritional content as compared to areas around schools with fewer students with lower SES. All outdoor food/beverage advertisements within a half-mile radius of 47 middle and high schools in the United States were objectively documented in 2012 and coded for nutritional content. The total number of advertisements and the macronutrient and micronutrient contents (total calories, fat (g), protein (g), carbohydrate (g), sugar (g), and sodium (mg)) of food and beverage items depicted in the advertisements were calculated. In total, 9132 unique advertisements were recorded, with 3153 ads displaying food and beverages that could be coded for nutrient content. Schools located in areas of lower SES (≥60% students receiving free/reduced-price lunch) had significantly more advertisements displaying food and beverages that could be coded for nutrient content (z = 2.01, p = 0.04), as well as advertisements that contained more sodium (z = 2.20, p = 0.03), as compared to schools located in areas of higher SES. There were no differences in calorie, fat, protein, carbohydrate, or sugar content. Policies to reduce the prevalence of outdoor food and beverage advertising are warranted.

Factors Associated with Food Delivery App use Among Young Adults.

Food delivery apps are popular among young adults and often used to purchase calorie-dense foods. Limited research exists on the use of food delivery apps among young adults. The purpose of this study was to describe food delivery app use among young adults and examine the correlates of food delivery app use. Data are from a panel of U.S. young adults aged 18-25 (n = 1,576) who completed an online survey between January-April 2022. Participants were 51.8% female and 39.3% identified as non-Hispanic white, 24.4% as Hispanic/Latinx, 29.6% as non-Hispanic Black, and 6.8% as another race/ethnicity. Poisson regression was used to examine the relationship between food delivery app use and age, race, ethnicity, sex, SES, food insecurity, living arrangement, financial responsibility, and full-time student status. Young adults used food delivery apps approximately twice a week. Participants who identified as non-Hispanic Black and Hispanic/Latinx used food delivery apps more frequently than participants who identified as white. Having higher perceived subjective social status, food insecurity, financial responsibility, and being a full-time student were significantly associated with using food delivery apps more frequently. Living with someone else was associated with using food delivery apps less frequently. This study provides a first step in understanding the characteristics of young adults who use food delivery apps. Given that food delivery apps are a new technology that can both increase access to unhealthy food options as well as healthy food options, further research is needed to better understand the types of food purchased through food delivery apps.

Exposure to tobacco retail outlet tobacco marketing and initiation of cigarette and e-cigarette use: Depressive symptoms as a moderator.

INTRODUCTION: While tobacco retail outlet (TRO) marketing exposure has been associated with tobacco use, little research has explored how this relationship may vary by the experience of depressive symptoms. The purpose of this study was to examine if the relationship between TRO tobacco marketing exposure and tobacco use initiation is moderated by depressive symptoms among young adults. METHODS: Participants were drawn from 24 colleges in Texas who were participating in a multi-wave cohort study (2014-2019). The present study included 2020 cigarette or ENDS naïve participants at wave 2 (69.2% female; 32.1% white; m age=20.6 [SD=2.0] at wave 1). Generalized mixed-effects logistic regression analyses were used to examine the association between cigarette and ENDS TRO marketing exposure and subsequent initiation for both products with depressive symptoms as a moderator. RESULTS: The interaction between cigarette marketing and depressive symptoms was significant (OR=1.38 95% CI=[1.04,1.83]). Cigarette marketing did not impact cigarette initiation among participants with low depressive symptoms (OR=0.96 95% CI= [0.64,1.45]), but did impact cigarette initiation among participants with high depressive symptoms (OR=1.83 95% CI=[1.23,2.74]). There was no interaction effect for ENDS initiation. Main effects showed that ENDS marketing exposure predicted ENDS initiation (OR=1.43 95% CI=[1.10,1.87]). CONCLUSIONS: Exposure to tobacco marketing at TROs is an important risk factor for initiation of cigarette and ENDS use, particularly for cigarette initiation among those who experience greater levels of depressive symptoms. Future work is needed to better understand why this type of marketing is influential for this group.

Alternative Tobacco Use and Cigarette Smoking Transitions among College Students in Texas.

Background: High prevalence of very light cigarette smoking and use of alternative tobacco products (ATPs; i.e. electronic nicotine delivery systems [ENDS], cigars, and hookah) among young adult college students are causes for concern. The purpose of this study is to examine transitions in cigarette smoking (never vs. non-current vs. very light vs. heavier) among college students across 2.5 years and determine if the use of ATPs is related to these transitions. Methods: This study used six waves of data across 2.5 years from Project M-PACT. Participants who were 18-25 years of age at baseline were included in this study (n = 4,806). Cigarette smoking state was categorized as never smoking, non-current smoking [0 cigarettes smoked per day (cpd) in past month], very light smoking (< =5 cpd in past month), and heavier smoking (>5 in past month). Multi-state Markov models were used to examine temporal transitions in the four smoking states and examine the association of time-varying current ATP use with transitions in smoking states. Results: The probabilities of remaining in a smoking state decreased over time. The time-varying current ATP use was significantly related to increased odds of transitioning from never smoking to non-current smoking, from never smoking to very light smoking, and from non-current to very light smoking. Conclusions: Findings highlight the need to prevent ATP use among college students and in turn inhibit initiation and escalation of cigarette smoking.

Longitudinal trajectories of marijuana use in tobacco products among young adult Texas college students from 2015 to 2019.

AIMS: To measure longitudinal trajectories of marijuana use in four tobacco/nicotine products (hand-rolled cigarettes/spliffs, cigars/blunts, hookah, and e-cigarettes) among young adult Texas college students from 2015 to 2019. DESIGN: This study used six consecutive waves of data from the marketing and promotions across colleges in Texas project (Project M-PACT), a longitudinal study of the tobacco behaviors of young adult college students. The first four waves were collected every 6 months (fall 2015-spring 2017), and the final two waves were conducted yearly (spring 2018 and 2019). Growth curve models measured trajectories of marijuana use in tobacco products across the 3.5-year period. SETTING AND PARTICIPANTS: A total of 4857 young adults from 24 colleges in the largest metropolitan areas of Texas, United States (Austin, Dallas, Houston, and San Antonio): mean age = 21.0, SD = 2.3; 64.2% assigned female; 36.1% non-Hispanic white, 31.0% Hispanic, and 33.0% other or combination race/ethnicity. MEASUREMENTS: Participants completed online surveys assessing their past 6-month use of marijuana in four tobacco products of interest (spliffs, blunts, hookah, and e-cigarettes) and socio-demographic variables (sex, race/ethnicity, age, 2-year/4-year college attendance, and sexual and gender minority identity). FINDINGS: Observed vaping marijuana in e-cigarettes approximately doubled between the spring of 2015 and the spring of 2019, from 11.8% to 23.9% following a quadratic time trend (linear OR = 0.84, 95% CI = 0.73-0.97, quadratic OR = 1.18, CI = 1.13-1.22). This same time period saw a quadratic decline in using marijuana in hookah (P < 0.001) and no changes in using hand-rolled cigarettes/spliffs or cigars/blunts for marijuana delivery. CONCLUSIONS: The popularity of nicotine e-cigarettes appears to be expanding the avenues for marijuana delivery among young adults in Texas, United States.

Electronic nicotine delivery systems (ENDS) dependence among Texas Young Adults, 2014-2019: Increasing trajectory after the 2017 surge in vape pod popularity.

INTRODUCTION: Use of electronic nicotine delivery systems (ENDS) increased significantly after 2017. The increase is attributed to a surge in popularity of vape pods containing nicotine salts, which are high nicotine concentration ENDS that may heighten risk for dependence. However, little is known about changes in ENDS dependence before and after the 2017 surge. We examined the trajectory of ENDS dependence among young adults from 2014 to 2019. METHODS: Participants were 1700 18-25-year-olds (57.6 % female) from 24 Texas colleges who reported past 30-day ENDS use in at least one of eight study waves. ENDS dependence was assessed at all waves with one item, use of ENDS within 30 min of waking. A discontinuous growth curve model was fit to test the hypothesis that the ENDS dependence trajectory would increase only after 2017, from 2018 to 2019. The model included socio-demographic and cigarette dependence covariates RESULTS: The proportion of young adults reporting ENDS dependence ranged from 2.3 % in 2014 to 8.2 % in 2019. Results from the discontinuous growth curve model indicated that the ENDS dependence trajectory was flat from fall 2014 to spring 2017. However, the post-2017 trajectory, from spring 2018 to spring 2019, was positive and significant indicating that the proportion of young adults reporting ENDS dependence increased after 2017. CONCLUSIONS: The increase in ENDS dependence after 2017 likely resulted from the surge in popularity of vape pods containing nicotine salts. These vape pods are a disruptive technology that may result in more young adults developing nicotine dependence symptoms than do earlier generation devices.

Longitudinal associations between U.S. youth exposure to E-cigarette marketing and E-cigarette use harm perception and behavior change.

E-cigarette marketing tactics to reach and appeal to youth are rapidly changing. This study examined to what extent youth e-cigarette marketing exposure was associated with e-cigarette use behavior change one year later, during a time when youth e-cigarette use was starting to surge in the U.S. Using nationally representative longitudinal public-use data from the Population Assessment of Tobacco and Health (PATH) Study, we examined associations between recalled e-cigarette marketing exposure (2016-2018) at Wave (W) 4 and e-cigarette use harm perception and behavior change (ever, current, and regular use) one year later (W4.5; 2017-2018) among W4 never tobacco users (n = 9405). Recall of exposure to e-cigarette marketing through different channels was also examined in multivariable models controlling for socio-demographic factors and established e-cigarette use risk factors. Results show that the most frequently recalled channels of e-cigarette marketing exposure were retail stores (50.3%), television (22.2%), and websites/social media (20.2%). Over one year, 21.2%, 7.8%, 3.4%, and 1.2% of respondents reported reduced harm perceptions, and ever, current, and regular use of e-cigarettes, respectively, at follow-up. Recalled exposure to e-cigarette marketing was associated with reduced e-cigarette harm perception (AOR = 1.20; 95% CI = 1.05-1.37) and ever (AOR = 1.26; 95% CI = 1.01-1.56) and current use (AOR = 1.40; 95% CI = 1.02-1.92) at follow-up. E-cigarette marketing exposure through websites/social media was associated with reduced harm perceptions and all stages of e-cigarette use change, including regular use. Identifying marketing techniques and channels that change youth e-cigarette harm perceptions and influence e-cigarette use progression is essential to inform e-cigarette regulatory policies and prevention campaigns.

Restricting Tobacco Retail Outlets Around Middle and High Schools as a Way to Reduce Tobacco Marketing Disparities: A Simulation Study.

INTRODUCTION: Communities with more people of color and economically disadvantaged residents are disproportionately exposed to tobacco marketing from tobacco companies. This study examined if banning tobacco retail outlets (TROs) within 1000 ft of schools would reduce these marketing disparities through a greater reduction in the amount of tobacco advertising around schools in these communities. METHODS: Data from objectively audited advertisement data from 106 convenience stores and gas stations around 42 middle and high schools located in the four major metropolitan areas of Texas were linked with schools' enrollment data. ArcGIS (Aeronautical Reconnaissance Coverage Geographic Information System) was used to simulate a 1000-ft ban of tobacco sales around the schools. Independent sample T-tests and Mann-Whitney U tests were used to test mean differences where appropriate. RESULTS: Schools with a higher enrollment of Hispanic/Latino (mean = 171.6, SD = 96.9) and economically disadvantaged students (mean = 168.9, SD = 102.3) were surrounded with significantly greater advertising at TROs than schools with lower enrollment of these groups (mean = 82.8, SD = 49.1 and mean = 89.2, SD = 50.6, respectively). A simulated 1000 ft ban of TROs around schools led to greater advertising reduction around schools with a higher enrollment of Hispanic/Latino students (13.3%-29.4% reductions) in comparison to schools with lower Hispanic/Latino student enrollment. However, the more economically disadvantaged schools had a smaller reduction in the number of advertisements (5.9%-21.9% reductions) in comparison to schools with less economically disadvantaged students. CONCLUSION: The implementation of a ban of tobacco sales at TROs within 1000 ft of schools is one policy approach to reduce youth exposure to tobacco marketing, particularly among students of color. STUDY IMPLICATION: Tobacco retail outlets (TROs) around schools with a higher enrollment of Hispanic/Latino and economically disadvantaged students had significantly more tobacco advertisements in comparison to schools with lower enrollment of these student groups. A simulated ban of TROs within 1000 ft of schools led to greater advertising reduction around schools with a higher enrollment of Hispanic/Latino students. For schools with more economically disadvantaged students, the ban led to a smaller reduction in advertisements in comparison to schools with less economically disadvantaged students. This proposed place-based strategy could be a successful means to reduce tobacco advertising and marketing disparity among communities of color.

Trajectories of depressive symptoms among young adults in Texas 2014-2018: a multilevel growth curve analysis using an intersectional lens.

INTRODUCTION: Research has demonstrated disparities in depressive symptoms among people who are marginalized. However, more work should examine depressive symptoms through an intersectional lens, recognizing that multiple systems of privilege and oppression interlock to create unique struggles where multiple marginalized identities meet. Recent methodological developments have advanced quantitative intersectionality research using multilevel modeling to partition variance in depressive symptoms to person-level sociodemographic variables and intersectional-level social strata. The purpose of this study is to leverage these methods to examine trajectories of depressive symptoms among young adults in Texas through an intersectional lens. METHODS: Multilevel modeling was used to examine the longitudinal trajectories of depressive symptoms among 3575 young adults from 24 colleges in Texas assessed seven times between Fall 2014 and Spring 2018. Intersectional identities included sex, race/ethnicity, and sexual and gender minority identities. The model examined time nested within individuals and individuals nested within intersectional social strata. RESULTS: Young adults in Texas experienced an increase in depressive symptoms from 2014-2018. Those with female, Hispanic, AAPI, other race/ethnicity, or LGBTQ + identities experienced more depressive symptoms. After controlling for the main effects of the sociodemographic variables, 0.08% of variance in depressive symptoms remained attributed to the effects of intersectional identities. CONCLUSION: Evaluating disparities in depressive symptoms through an intersectional lens offers a more complete description of the epidemiology of depressive symptoms. Communities and institutions that serve marginalized people should consider the elevated burden of depressive symptoms that marginalized people may carry, and integrate culturally competent psychoeducation, assessments, and therapies where possible.

A Simulation of the potential impact of restricting tobacco retail outlets around middle and high schools on tobacco advertisements.

OBJECTIVE: To examine (1) if tobacco retail outlets (TROs) closer to middle and high schools have more tobacco advertisements than TROs farther away and (2) the potential impact of two place-based tobacco control strategies on tobacco advertisements: a simulated ban of TROs (1) within 1000ft of schools and (2) within 500 ft of other TROs. METHODS: TROs within half-mile of 53 middle and high schools in the four largest Metropolitan areas in Texas were audited for all tobacco marketing. ArcGIS was used for mapping and grouping TROs by distance from the schools and simulating the ban. Mean differences in the number of tobacco advertisements were examined with t-tests. Percentage reductions in tobacco advertisements were calculated after simulation of both bans, reported by school type and by location, product and flavour. RESULTS: TROs within 1000 ft of schools had significantly more tobacco advertisements as compared with TROs located within 1000-2000 ft (p=0.03) for all schools combined and middle schools. Simulation of the 1000 ft ban of TROs led to a slightly greater reduction in advertisements (19.4%) as compared with the 500 ft ban of TROs from other TROs (17.9%). The reduction in all advertisement types was greater around middle schools and greatest for e-cigarettes (23.6%). CONCLUSION: Students can be exposed to a great deal of tobacco advertising in TROs around their schools. The implementation of a 1000 ft ban of TROs, or at minimum a ban on tobacco advertising outside and within these outlets, is one way to prevent or reduce the use of tobacco among adolescents.

Rising vape pod popularity disrupted declining use of electronic nicotine delivery systems among young adults in Texas, USA from 2014 to 2019.

AIMS: To examine the longitudinal trajectory of young Texan (US) adults' electronic nicotine delivery systems (ENDS) use from 2014 to 2019, and to determine if there are changes in the trajectory among younger and older young adults post-2017, when vape pods surged in popularity in the United States. DESIGN: Nine-wave longitudinal study, with 6 months between each of the first eight waves and 1 year between the last two waves. Discontinuous, or piecewise, growth curve models were used to test the hypotheses that (a) the overall current/past 30-day ENDS use trajectory would decline from 2014 to spring 2017 but then increase from fall 2017 to 2019, and (b) the increasing trajectory from 2017 to 2019 would occur only for younger participants, but not older participants. All models included socio-demographic covariates of sex, race/ethnicity, type of college attended at baseline (2- or 4-year) and time-varying age. SETTING AND PARTICIPANTS: A total of 5218 students (aged 18-25 years at baseline; 63.7% female) from 24 colleges in the five counties surrounding Austin, Dallas/Fort Worth, Houston and San Antonio, Texas, USA. MEASUREMENTS: Participants completed on-line surveys regarding past 30-day ENDS use at all nine waves. FINDINGS: Current ENDS use significantly declined from 2014 to spring 2017 [odds ratio (OR) = 0.63, 95% confidence interval (CI) = 0.59-0.68], and then significantly increased from autumn 2017 to 2019 (OR = 1.14, 95% CI = 1.01-1.29). Further examination indicated the increase in current ENDS use from autumn 2017 to 2019 occurred only for younger [-1 standard deviation (SD) below the mean age, 22.6 years old], but not older (+1 SD above the mean age, 26.2 years old), participants. CONCLUSION: The surge in the popularity of vape pods in the United States in late 2017 may have contributed to increasing use of electronic nicotine delivery systems among younger young adults (below 22.6 years) from late 2017 to 2019.

Qualities of the Restaurant Food Environment: A Direct Observation Pilot Study of Restaurants Located Near High Schools.

Objective: This study aimed to identify and describe healthful and youth-oriented qualities of the restaurant food environment around high schools. Methods: Using direct observation data from 58 restaurants located within a half-mile (804.5 meters) of all high schools in a single district, two index measures of the restaurant food environment were created: healthfulness index and youth-oriented index. Wilcoxon signed-rank order was used to examine differences in restaurant features according to index scores. Results: Mean healthfulness score was 8.9 (range = 2-14, max = 19) and mean youth-oriented score was 5.5 (range = 0-11, max = 12). Differences were found in signed-rank order of healthfulness and youth-oriented index restaurant scores (p = 0.02). Conclusion: Results suggest that restaurants have room for improvement in offering customers a healthful environment, some restaurants are more likely to appeal to youth, and that youth-oriented restaurants were different than restaurants with high healthfulness scores. Further qualitative exploration of food environment features will help contextualize the influence of restaurants on youth eating behaviors.

Exposure to cigar Point-of-Sale marketing and use of cigars and cigarettes among young adults.

INTRODUCTION: Few studies examine the impact of objective exposure to point-of-sale (POS) marketing for cigars including little cigars and cigarillos (LCCs) on tobacco use. The present study aimed to examine the relationship between exposure to LCC marketing at the POS and current and future use of LCCs and cigarettes among young adult college students. METHOD: Data on LCC and cigarette use from 4201 young adult students (mean age = 22.8 [SD = 2.3]; 35.9% non-Hispanic whites) attending 24 Texas colleges was linked to objective assessments of POS marketing at 220 tobacco retail outlets within one mile of the colleges. Multilevel logistic regression analyses examined the impact of LCC marketing at the POS on use of LCCs and cigarettes currently and 6-months later. RESULTS: Participants were, on average, exposed to 43 LCC marketing materials per week. Results from cross-sectional analyses indicated that exposure to LCC POS marketing was associated with higher odds of current use of LCCs (AOR = 1.003, 95% CI = 1.0002, 1.0053) and cigarettes (AOR = 1.006, 95% CI = 1.0050, 1.0075). The relationship between LCC POS marketing exposure and LCC use was not significant in longitudinal models; however, exposure to LCC POS marketing at baseline did predict current cigarette use at 6-month follow-up (AOR = 1.004, 95% CI = 1.0021, 1.0052). CONCLUSION: Findings suggest a substantial influence of LCC marketing exposure at the POS. Regulations on LCC marketing at the POS, especially around college campuses, should be considered.

Tobacco Magazine Advertising Impacts Longitudinal Changes in the Number of Tobacco Products Used by Young Adults.

PURPOSE: The present study examined the longitudinal associations between exposure to tobacco advertisements in magazines popular among young adults and changes in the number of tobacco products used by young adults. METHODS: Participants were 4,824 students from 24 Texas colleges participating in a longitudinal study. Tobacco advertisements in 11 magazines, collected from 2015 to 2017, were objectively assessed and young adults self-reported the frequency of reading each magazine on five biannual surveys from 2015 to 2017. The objective and self-reported measures were multiplied to create a tobacco advertisement exposure score. Growth curve models were used to determine if exposure to tobacco advertisements in magazines predicted changes in the number of tobacco products used across the 2-year period, controlling for sociodemographic factors, ever tobacco use, recall of tobacco advertisements on the internet, and personality characteristics. RESULTS: Young adults with more exposure to tobacco advertisements reported a slower decline in the number of tobacco products they used across time. CONCLUSIONS: Tobacco advertising in magazines contributes to the continuation of single-product and polyproduct use among young adults. Findings highlight the need for additional federal regulations limiting advertisements for all types of tobacco products in magazines, particularly those popular among young adults, the youngest legal targets of the tobacco industry.

Child disclosure, parental solicitation, and adjustment problems: Parental support as a mediator.

Little is known about how perceived parental solicitation and child disclosure are negatively associated with early adolescent adjustment problems and/or if these associations are consistent across race/ethnic groups. This study used data from 209 early adolescents to examine perceived parental support as a mediator in the associations between perceived parental solicitation and child disclosure and subsequent adjustment problems, while also examining race/ethnic group differences across non-Hispanic White and Hispanic early adolescents using multi-group path analyses. Perceived parent support did not mediate the associations between child disclosure and perceived parental solicitation and subsequent adjustment problems. However, child disclosure was directly associated with subsequent conduct problems for Hispanic adolescents. Child disclosure and perceived parental solicitation may positively influence the parent-adolescent relationship by increasing parental support but may not entirely help in reducing the prevalence of adjustment problems. Child disclosure may be particularly beneficial for Hispanic early adolescents in reducing adjustment problems.
