RESUMO

OBJECTIVE: This work examines the relationship between local flavor policy exposure and any tobacco product use and flavored tobacco product use among U.S. youth and young adults, as well as the equity potential of these policies by race/ethnicity. METHODS: Participants were aged 15-36 (n = 10,893) surveyed from September-December 2019 using national, address- and probability-based sampling. Local flavor policies enacted before survey completion were linked to participant home address. Weighted cross-sectional multivariable logistic regression examined individual coverage by flavor policy vs. no flavor policy, with current any tobacco or flavored tobacco use, controlling for individual and county-level demographics, psychosocial variables, and other tobacco control policies. Interactions between race/ethnicity and any tobacco use and flavored tobacco use were assessed. RESULTS: Those covered by a flavor policy vs. no policy had lower odds of any tobacco use (aOR = 0.74, 95% CI = 0.55-1.00) and current flavored tobacco use (aOR = 0.67, 95% CI = 0.48-0.93). Compared with Non-Hispanic (NH)-White individuals, NH-Black individuals (aOR = 1.08, CI = 1.04-1.12) had higher odds of any tobacco use, and non-Hispanic Asian individuals had lower odds of any tobacco use (aOR = 0.67, CI = 0.53-0.85). Hispanic individuals exposed to policy had lower odds of flavored tobacco use compared to NH-White peers. CONCLUSIONS: Exposure to flavor restriction policies is associated with lower odds of any tobacco and flavored use among youth and young adults. Flavor restrictions may be beneficial in reducing tobacco use in youth from diverse racial/ethnic backgrounds. However, passing policies covering NH-Black individuals is needed to mitigate disparities in tobacco use by flavor policy coverage over time.

RESUMO

INTRODUCTION: Prior research on the effects of social media promotion of tobacco products has predominantly relied on survey-based self-report measures of marketing exposure, which potentially introduce endogeneity, recall, and selection biases. New approaches can enhance measurement and help better understand the effects of exposure to tobacco-related messages in a dynamic social media marketing environment. We used geolocation-specific tweet rate as an exogenous indicator of exposure to smokeless tobacco (ST)-related content and employed this measure to examine the influence of social media marketing on ST sales. AIMS AND METHODS: Autoregressive error models were used to analyze the association between the ST-relevant tweet rate (aggregated by 4-week period from February 12, 2017 to June 26, 2021 and scaled by population density) and logarithmic ST unit sales across time by product type (newer, snus, conventional) in the United States, accounting for autocorrelated errors. Interrupted time series approach was used to control for policy change effects. RESULTS: ST product category-related tweet rates were associated with ST unit sales of newer and conventional products, controlling for price, relevant policy events, and the coronavirus disease 2019 (COVID-19) pandemic. On average, 100-unit increase in the number of newer ST-related tweets was associated with 14% increase in unit sales (RR = 1.14; p = .01); 100-unit increase in conventional ST tweets was associated with ~1% increase in unit sales (p = .04). Average price was negatively associated with the unit sales. CONCLUSIONS: Study findings reveal that ST social media tweet rate was related to increased ST consumption and illustrate the utility of exogenous measures in conceptualizing and assessing effects in the complex media environment. IMPLICATIONS: Tobacco control initiatives should include efforts to monitor the role of social media in promoting tobacco use. Surveillance of social media platforms is critical to monitor emerging tobacco product-related marketing strategies and promotional content reach. Exogenous measures of potential exposure to social media messages can supplement survey data to study media effects on tobacco consumption.

RESUMO

The tobacco industry spends the vast majority of their marketing and promotional budget at retail outlets. However, few studies have used publicly available data to examine trends in the number and types of retail establishments where tobacco products are sold. Using the U.S. Economic Census for 1997, 2002, 2007, 2012 and 2017 (the latest year), we examined the number, type, and sales of payroll establishments selling tobacco products. Nine store types accounted for 94% - 99% of tobacco product sales between 1997 and 2017. Gas/convenience stores had the greatest market share (33% - 49% of tobacco sales). The number of warehouse clubs selling tobacco quadrupled; however, market share only increased from 9.6% to 10.3%. Supermarkets experienced the largest decrease in percent of stores selling tobacco. Pharmacy tobacco sales increased in 2012 then decreased in 2017; per store sales volume more than doubled between 1997 and 2012. Online shopping accounted for less than 1% of the market share between 1997 and 2012, but rose to 6.3% in 2017. Between 1997 and 2017, consumers shifted where they purchased tobacco products. Declining tobacco sales in supermarkets is a promising trend for consumers seeking healthy food without exposure to tobacco product marketing; however, the consistently large number of tobacco retailers, and thus widespread tobacco availability, is concerning. Consumer tobacco purchase changes over time support the case for point-of-sale policies that affect different retail types, including pharmacy bans, to reduce tobacco retailer density. Additionally, the rapid shift to online tobacco purchasing in 2017 identifies a new target for enhanced regulation and enforcement.

RESUMO

OBJECTIVE: Nicotine pouch products are an emerging and rapidly growing smokeless tobacco (ST) category in the USA. Little is known about the promotional strategies and media channels used to advertise this ST category or the extent to which the marketing strategies differ from strategies used to promote 'conventional' smokeless products (eg, snuff). We describe the nature, timing of and expenditures related to conventional, snus and newer ST product advertising on print, broadcast and internet media. METHODS: Advertising expenditures were collected using Kantar Media's 'Stradegy' tool, which provides advertising data including dollars spent promoting specific products across various media channels, including print magazines and newspapers, broadcast television and radio, outdoor posters and billboards, and internet. We identified 306 smokeless products within Kantar database and collected ad expenditures retrospectively for January 2018-April 2020. Promotional expenditures were aggregated by product category, by month and by designated market area (DMA). RESULTS: Kantar data analysis returned 28 conventional ST, 22 oral nicotine and 3 snus products (53 total) advertised during the period of observation, with over $71 million spent collectively on ST promotion. Across categories, more advertising dollars were spent on conventional ST products (63%) than newer oral nicotine products (25%) or snus (12%). However, during the later 9-month period from August 2019 to April 2020, oral nicotine products accounted for the majority of monthly ad spending. Most ad spending was placed in the national market ($66.5 million), with Atlanta ($1.1 million), Houston ($1 million) and Las Vegas ($0.8 million) as the top three local DMAs for expenditures. DISCUSSION: Advertising expenditures for nicotine pouches have recently exceeded conventional ST product advertising and nicotine pouches are being promoted nationally. Marketing surveillance as well as understanding consumer appeal, perceptions and consumption are critical next steps in tracking potential uptake of these new products.

RESUMO

INTRODUCTION: To eliminate tobacco-related disparities, tobacco control research would benefit from a paradigm shift. Intersectionality, a framework pioneered by Kimberlé Crenshaw in late 1980s, has the potential to improve our understanding of why and how certain social groups are disproportionately harmed by commercial tobacco use, and improve our ability to address persistent tobacco-related health disparities. AIMS AND METHODS: In this commentary, we outline the rationale and recommendations for incorporating intersectionality into equity-minded tobacco control research. These recommendations arose from intersectionality webinars organized by the Health Disparities (now Health Equity) Network of the Society for Research on Nicotine & Tobacco (SRNT) in 2019 and 2020. RESULTS: Specifically, we propose that eliminating tobacco-related disparities through intersectionality-informed research requires a multilevel, multipronged approach. We summarize priority actions for the tobacco control research field to achieve health equity through the intersectionality framework including acknowledging that structural factors, racism and power dynamics shape lived experiences, integrating critical theoretical frameworks and intersectionality scholarship into research questions, and embracing collaborative community-based approaches at every level of the research process. CONCLUSIONS: Through these actions, our field can take concrete steps to fundamentally improve our approach to conducting research to achieve health equity. IMPLICATIONS: Intersectionality is a valuable tool to align our field with our pursuit of health equity. The recommendations aim to improve methods of equity-focused tobacco control, prompt ongoing dialogue on the utility of this tool, and shift paradigms in how the research process is conducted at every level among stakeholders, including researchers, journal editors and reviewers, funders, practitioners, and policy makers.

RESUMO

INTRODUCTION: Black communities are targeted by more cigarette advertisements than White communities and racial discrimination among Black people is related to cigarette use. However, little is known about these factors with non-cigarette tobacco product use among Black adults. Therefore, this study assessed the association of non-cigarette advertisement exposure and racial discrimination with use of non-cigarette tobacco products among Black adults. AIMS AND METHODS: Black adults (n = 533) from The Family and Community Health Study in 2016 were asked if they had seen advertisements for e-cigarettes, snus pouches, filtered cigars, large cigars, cigarillos, dissolvable tobacco, smokeless tobacco, hookah, and tobacco pipe and if they used these in the past month. For products with the highest past month use and significant correlations with advertisement exposure, separate logistic regression models were performed that evaluated the association between advertisement exposure, racial discrimination, and non-cigarette tobacco product use while controlling for cigarette use, sex, socioeconomic status, and age. RESULTS: Use of cigarillos, large cigars, and hookah were higher than other non-cigarette tobacco products assessed. Logistic regressions revealed that more advertisement exposure in the past month was associated with higher odds of using cigarillos, large cigars, and hookah (p < .01). More experiences of racial discrimination were associated with past month cigarillo use, but not hookah or large cigars (p < .01). CONCLUSIONS: Non-cigarette tobacco advertisement exposure was associated with the use of non-cigarette tobacco products. Experiences of racial discrimination were associated with the most used non-cigarette tobacco product among Black adults, cigarillos. IMPLICATIONS: This is the first time that a specific type of cigar (ie cigarillos) has been associated with experiences of racial discrimination among Black adults. Efforts to reduce non-cigarette tobacco marketing and eradicate exposure to racial discrimination among Black adults may aid in eliminating tobacco-related health disparities.

RESUMO

Audits of tobacco retailers can identify marketing patterns as newer tobacco products are introduced in the US. Our study examined store and neighborhood correlates of availability of nicotine pouches and disposable e-cigarettes in four US sites. We conducted standardized store audits of n = 242 tobacco retailers in 2021 in different states: New Jersey, Kentucky, North Carolina, and New York. We geocoded stores linking them with census tract demographics. We conducted unadjusted and adjusted Poisson regression of availability of each product with correlates of the proportion of Non-Hispanic White residents, households under poverty, proximity to schools, site, and store type. Nicotine pouches and disposable e-cigarettes were each available in around half the stores overall, but availability differed across sites (range: 76 %-32 %). In adjusted analyses, nicotine pouches were less likely to be available in each store type vs chain convenience (IRR range 0.2-0.6) and more likely in stores in census tracts with a greater percentage of non-Hispanic White residents (IRR range 1.8-2.3). In contrast, disposable e-cigarettes were more likely to be available in tobacco/vape shops (IRR 1.9 (1.4-2.5) than convenience stores and less likely in non-specialty store types like groceries (IRR 0.2 (0.1-0.4). Newer tobacco products like nicotine pouches and disposable e-cigarettes were widely available in stores across sites, but retail marketing patterns appear to differ. As these product types become subject to increased regulation as they go through the FDA pre-market authorization process, understanding patterns and changes in the retail environment is critical to inform potential policies regulating their sale and marketing.

RESUMO

Tobacco use, typically initiated during adolescence, can escalate into young adulthood, even among experimenting or intermittent users. Despite declines in cigarette smoking among US adolescents, use of other tobacco products and poly-tobacco are on the rise among Appalachian adolescents. Unfortunately, Appalachian adolescent tobacco users also are less likely to receive effective tobacco interventions due to various barriers: a) accessibility (e.g. service and provider shortages, affordability, and transportation; b) acceptability (e.g. issues of privacy and stigma); and c) cultural relevance. The present review provides critical considerations synthesized from an extensive body of literature on the suitability of virtual tobacco interventions, the need for well-timed interventions that address complex tobacco use, and the rationale for leveraging and scaling evidence-based interventions inform novel interventions for Appalachian adolescent tobacco users. Borrowing strength from existing in-person evidence-based adolescent tobacco interventions and state-of-the-art virtual health services, a well-planned virtual scale out of tobacco interventions holds potential to minimize barriers unique to Appalachia.

RESUMO

To achieve equity in protection from poor health outcomes due to tobacco use, tobacco control policies and interventions need to affect socially disadvantaged groups more strongly than advantaged groups. Flavored tobacco bans have been seen as a policy with this potential. However, tobacco control researchers, in close concert with policy advocates, need to consider how to center equity throughout the policy process to achieve equitable outcomes from banning flavored tobacco. In this commentary, we outline the rationale for how and why tobacco control researchers should consider equity throughout the policy process to help fully achieve the potential of flavored tobacco ban policies. These recommendations emerged from a presentation at the Vermont Center on Behavior and Health 2021 Conference. Specifically, we focus on recommendations for tobacco control researchers to center equity including partnering with communities in agenda setting, examining how various policy formulations or exemptions may increase or decrease disparities, determining where flavor policies need to reach and whether policies are equitably reaching all populations disproportionately burdened by flavored tobacco, assessing whether policy implementation/enforcement is carried out equitably to maximize policy benefits, and evaluating policy impact with as much granularity as possible. Considering the entire policy process is central to enhancing equitable outcomes from banning flavored tobacco. Tobacco control researchers can play a key role in ensuring that these policies are viewed through an equity lens to, not just improve population health, but also to reduce harms to those disproportionately burdened by use of flavored products.

RESUMO

OBJECTIVE: To understand the relationship between exposure to online tobacco advertising and current smokeless tobacco use in the context of tobacco control policies. METHODS: Three waves of a national probability-based sample of (n = 15,985) youth and young adults were used. Analysis consisted of GEE logistic models controlling for social media use, demographics, tobacco use, average price of smokeless tobacco inclusive of taxes, smoke-free indoor air laws (SFIA) and state tobacco control expenditures. RESULTS: Frequent exposure to tobacco advertising on social media is associated with greater odds of current smokeless use (aOR: 2.05, 95% CI: 1.62, 2.60). Higher prices and SFIA coverage were associated with reduced current smokeless use when examined separately from other tobacco policy variables (aOR: 0.79, CI: 0.73, 0.85; aOR: 0.44, CI: 0.28, 0.70). CONCLUSIONS: Greater exposure to tobacco advertising online is associated with greater odds of smokeless use among surveyed youth and young adults. This effect of social media marketing exposure on smokeless use outweighs the mitigating impact of existing tobacco control policies. The findings underscore the need for strong advertising regulation of evolving tobacco products, including smokeless products, on social media and surveillance of digital marketing tactics to young people.

RESUMO

INTRODUCTION: The present study examines the contributions of individual-level health determinants on young adult tobacco use initiation to improve understanding of racial and ethnic distinctions and to inform effective tobacco prevention strategies. METHODS: Using time-to-event analyses, the 10-wave (2011-2016) Truth Initiative Young Adult Cohort, a probability-based, nationally representative sample of the US young adults aged 18-34 years (N = 7 665), provides data to examine differences in variables that influence tobacco uptake, by race and ethnicity. RESULTS: Among Non-Hispanic White young adults, having fewer peers who smoke cigarettes is protective against any tobacco initiation, whereas hazard of tobacco initiation increases for males, having low confidence to resist smoking, and having higher proclivity for sensation seeking. Depressive and anxiety symptoms increase uptake hazard most in the Non-Hispanic All Other Races group and least among Non-Hispanic Black individuals. Among Hispanic young adults, being female and perceiving tobacco as harmful are notably protective while being male is a notable uptake hazard. Unlike other groups, higher income levels do not lower hazards among Hispanic individuals. Cannabis use and overestimating the smoking rate among peers increase hazard least among Hispanic individuals. In the Non-Hispanic All Other Races group, aging is least protective; hazard increases notably if individuals engage in regular alcohol or cannabis use. CONCLUSIONS: Tobacco prevention efforts are critical during young adulthood. Specific tobacco uptake hazard and protective factors exist by race and ethnicity and should be considered when developing selective young adult prevention, particularly among groups with the highest risk for tobacco initiation during this life stage. IMPLICATIONS: Rising rates of tobacco initiation among the US young adults necessitate expanded efforts to prevent tobacco use initiation and progression beyond youth. Results highlight nuanced and differential tobacco uptake hazards by race and ethnicity for late initiation and sustained non-tobacco use among young adults. The study confirms existing evidence on tobacco use patterns and contributes to new knowledge on risk and protective factors. Tobacco prevention and control interventions, including policies, tailored in more meaningful ways could reduce tobacco use disparities among those most disproportionately affected.

RESUMO

INTRODUCTION: Flavored tobacco products (FTPs) are disproportionately used among young people and racial/ethnic minority populations. However, few studies have examined the retail distribution of such product marketing beyond menthol cigarettes. This study created geographic-based predictions about marketing of FTPs (overall, cigarettes, cigars, e-cigarettes, and smokeless) in stores across Washington, DC neighborhoods. We examined neighborhood-level demographic correlates of the amount of FTP and non-FTP marketing. METHODS: We conducted photographic audits of interior and exterior tobacco marketing in 96 Washington, DC tobacco retailers visited by 149 young adult respondents between 2018-2019. We created a geographic predictive surface of overall and product-specific tobacco marketing and then estimated the average predicted amount of marketing at the census-tract level using zonal statistics. Using linear regression, we examined neighborhood demographic correlates (race/ethnicity, family poverty, and youth population under 18) of FTP and non-FTP marketing. RESULTS: The predicted amount of non-FTP ads/displays were evenly distributed with no neighborhood variability (Range 8.46-8.46). FTP marketing overall was geographically concentrated with greater range across neighborhoods (Range 6.27-16.77). Greater FTP marketing overall and flavored cigar marketing was available in neighborhoods with higher percentages of Black residents. Flavored cigar marketing was less available in neighborhoods with more Hispanic residents, but there was greater flavored smokeless tobacco marketing. Nonflavored marketing overall and by product did not vary across neighborhoods. CONCLUSIONS: This study provides evidence of disproportionate distribution of FTP marketing in Black neighborhoods, especially for flavored cigars, at the point-of-sale. Policies that restrict the sale of FTPs may enhance health equity. IMPLICATIONS: Tobacco marketing has frequently been shown to be more prevalent in neighborhoods with lower household income and more Black residents. Using geographic-based predictions, we find that greater flavored tobacco marketing in these neighborhoods, not decreased marketing for nonflavored tobacco, is driving this disparity. Targeting Black neighborhoods with increased marketing of flavored tobacco products, which has been found to be more appealing, easier to use, and harder to quit is a social justice issue.

RESUMO

BACKGROUND: Exposure to tobacco product marketing increases tobacco use among young adults, especially those from vulnerable communities (VCs). PURPOSE: This study examined real-time tobacco marketing exposure among young adults from vulnerable and non-vulnerable communities using Ecological Momentary Assessment (EMA). METHODS: This study used EMA data to assess context (e.g., location and activity) of tobacco marketing exposure using four text-messaging surveys per day over 2 weeks. Young adult non-current tobacco users living in Washington, D.C. (n = 146; ages 18-24) recorded 5,285 surveys, including 20 participants (13.2%) from VCs with high proportions of lower income and racial/ethnic minorities, and high smoking rates. Unadjusted and adjusted multilevel logistic regressions were used to assess the associations between exposure to any and flavored tobacco marketing, VC residence, and real-time context. RESULTS: Fifty-nine participants (40.4%) reported at least one tobacco marketing exposure and recorded 94 exposure moments. In adjusted models, odds of exposure were higher among VC residents (AOR = 2.6, 95% CI = 1.2-5.4), in the presence of anyone using tobacco versus no use (AOR = 4.0, 95% CI = 2.4-6.7), at store/retail (AOR = 17.0, 95% CI = 6.4-44.8), or outside/in transit (AOR = 4.1, 95% CI = 2.1-7.8) versus at home. VC residence (AOR = 7.2, 95% CI = 2.3-22.2) was the strongest predictor of flavored tobacco marketing exposure among all covariates examined. CONCLUSIONS: Young adults are predominantly exposed to tobacco marketing in their daily lives through retail advertisements. Young adults from VCs are at increased risks of seeing any tobacco and especially flavored tobacco marketing. Policies that curtail tobacco retailer density and advertisement displays may reduce overall and differential tobacco marketing exposure.

RESUMO

BACKGROUND: Little is known regarding how oral nicotine products (eg, nicotine pouches, lozenges) are marketed to consumers, including whether potential implicit reduced harm claims are used. In the current study, we explored the marketing claims present in a sample of direct-mail oral nicotine advertisements sent to US consumers (March 2018-August 2020). METHODS: Direct-mail ads (n=50) were acquired from Mintel and dual-coded for the following claims: alternative to other tobacco products, ability to use anywhere, spit-free, smoke-free and product does not contain tobacco leaf. We merged the coded data with Mintel's volume estimate (number of mail pieces sent to consumers) and calculated the proportion of oral nicotine advertisements containing claims by category. RESULTS: Of the 38 million pieces of oral nicotine direct-mail sent to US consumers, most featured claims that the product could be used anywhere (84%, 31.8 million pieces); was an alternative to other tobacco products (69%, 26.1 million pieces); and did not contain tobacco leaf (eg, 'tobacco leaf-free', 'simple' approach of extracting nicotine from tobacco; 55%, 20.7 million pieces). A slightly smaller proportion contained claims that oral nicotine was 'spit-free' (52%, 19.8 million pieces) or 'smoke-free' (31%, 11.7 million pieces). CONCLUSION: Our results provide an early indication of marketing claims used to promote oral nicotine. The strategies documented, particularly the use of language to highlight oral nicotine is tobacco-free, may covey these products as lower-risk to consumers despite the lack of evidence or proper federal authorisation that oral nicotine products are a modified-risk tobacco product. Future research is needed to examine consumer perceptions of such claims.

RESUMO

BACKGROUND: An unproven "nicotine hypothesis" that indicates nicotine's therapeutic potential for COVID-19 has been proposed in recent literature. This study is about Twitter posts that misinterpret this hypothesis to make baseless claims about benefits of smoking and vaping in the context of COVID-19. We quantify the presence of such misinformation and characterize the tweeters who post such messages. METHODS: Twitter premium API was used to download tweets (n = 17,533) that match terms indicating (a) nicotine or vaping themes, (b) a prophylactic or therapeutic effect, and (c) COVID-19 (January-July 2020) as a conjunctive query. A constraint on the length of the span of text containing the terms in the tweets allowed us to focus on those that convey the therapeutic intent. We hand-annotated these filtered tweets and built a classifier that identifies tweets that extrapolate the nicotine hypothesis to smoking/vaping with a positive predictive value of 85%. We analyzed the frequently used terms in author bios, top Web links, and hashtags of such tweets. RESULTS: 21% of our filtered COVID-19 tweets indicate a vaping or smoking-based prevention/treatment narrative. Qualitative analyses show a variety of ways therapeutic claims are being made and tweeter bios reveal pre-existing notions of positive stances toward vaping. CONCLUSION: The social media landscape is a double-edged sword in tobacco communication. Although it increases information reach, consumers can also be subject to confirmation bias when exposed to inadvertent or deliberate framing of scientific discourse that may border on misinformation. This calls for circumspection and additional planning in countering such narratives as the COVID-19 pandemic continues to ravage our world. Our results also serve as a cautionary tale in how social media can be leveraged to spread misleading information about tobacco products in the wake of pandemics.

RESUMO

BACKGROUND: With a rapidly evolving tobacco retail environment, it is increasingly necessary to understand the point-of-sale (POS) advertising environment as part of tobacco surveillance and control. Advances in machine learning and image processing suggest the ability for more efficient and nuanced data capture than previously available. OBJECTIVE: The study aims to use machine learning algorithms to discover the presence of tobacco advertising in photographs of tobacco POS advertising and their location in the photograph. METHODS: We first collected images of the interiors of tobacco retailers in West Virginia and the District of Columbia during 2016 and 2018. The clearest photographs were selected and used to create a training and test data set. We then used a pretrained image classification network model, Inception V3, to discover the presence of tobacco logos and a unified object detection system, You Only Look Once V3, to identify logo locations. RESULTS: Our model was successful in identifying the presence of advertising within images, with a classification accuracy of over 75% for 8 of the 42 brands. Discovering the location of logos within a given photograph was more challenging because of the relatively small training data set, resulting in a mean average precision score of 0.72 and an intersection over union score of 0.62. CONCLUSIONS: Our research provides preliminary evidence for a novel methodological approach that tobacco researchers and other public health practitioners can apply in the collection and processing of data for tobacco or other POS surveillance efforts. The resulting surveillance information can inform policy adoption, implementation, and enforcement. Limitations notwithstanding, our analysis shows the promise of using machine learning as part of a suite of tools to understand the tobacco retail environment, make policy recommendations, and design public health interventions at the municipal or other jurisdictional scale.
