Tobacco Industry Marketing Exposure and Commercial Tobacco Product Use Disparities among American Indians and Alaska Natives

Recruitment Methods, Inclusion, and Successful Participation in a Longitudinal Clinical Trial Using Ecological Momentary Assessment

Underrepresentation of historically marginalized populations in clinical trials continues to threaten the validity of health intervention research. Evidence supports the merits of intercept and other proactive forms of recruitment for achieving more equitable representation. However, researchers also report lower retention and adherence to protocols among these populations, particularly in longitudinal studies. Few studies have compared recruitment methods for longitudinal randomized trials testing health interventions, with even fewer having done so for trials involving ecological momentary assessment (EMA). As intervention research integrates EMA and other data collection approaches requiring substantial participant effort, it is critical to better understand the effectiveness and implications of strategies to improve the representativeness of health research. This secondary data analysis compared outcomes of proactive and reactive recruitment strategies (mobile lab intercepts and internet/flyer advertising, respectively) in study inclusion, task completion, and retention within a 14-day randomized controlled trial that used EMA to evaluate cigarette package health messages. Proactive recruitment resulted in higher proportions of participants with low income and education, limited health literacy, and of diverse racial/ethnic makeup. However, this recruitment method also resulted in lower task completion, especially in the second week of the trial period, and lower retention, although group differences were not explained by participant sociodemographic characteristics targeted by inclusion efforts. We conclude that proactive recruitment via intercepts is an effective strategy for health intervention research that aims to include stakeholders from historically marginalized groups but that researchers and funders must recognize these methods require additional resources, considerations, and capacity to address non-trivial challenges to successful participation.

California's tobacco 21 minimum sales age law and adolescents' tobacco and nicotine use: differential associations among racial and ethnic groups

OBJECTIVE

A California, USA, law raised the minimum tobacco sales age to 21 (T21) on 9 June 2016. We investigated whether T21 was associated with reductions adolescents' use of tobacco cigarettes, smokeless tobacco and electronic cigarettes and whether these associations differed across racial and ethnic groups.

METHODS

Secondary analyses of data from 2 956 054 7th, 9th and 11th grade students who participated in the California Healthy Kids Survey from 2010-11 to 2017-2018.

RESULTS

Multilevel mixed effects logistic regression analyses showed that T21 was associated with reduced prevalence of lifetime smokeless tobacco and e-cigarette use and past month smokeless tobacco use in the overall student population. T21 was associated with increases in prevalence of past month e-cigarette use. Moderation analyses indicated differences by racial and ethnic groups. Notably, T21 was associated with reductions in lifetime and past 30-day use of all tobacco and nicotine products among Latinx youth. The findings were more mixed for other racial and ethnic groups. Slopes analyses indicated that T21 was associated with accelerated downward trends for 30-day cigarette and smokeless use; moderated trends for lifetime cigarette smoking such that downward slopes became less steep; and reversed downward trends for e-cigarette use. Changes in slopes varied across racial and ethnic groups.

CONCLUSIONS

Our findings highlight the importance of understanding the complex associations that T21 and other tobacco control policies have with the use of different tobacco and nicotine products among racial and ethnic groups. Future research should investigate mechanisms underlying these differences to inform tobacco control efforts.

Centering racial justice for Black/African American and Indigenous American people in commercial tobacco product regulation

Although overall health in the United States (US) has improved dramatically during the past century, long-standing health inequities, particularly the unequal and unjust burden of tobacco-related disease and death among racialized populations, persist. A considerable gap exists in our understanding of how commercial tobacco product regulations and policies cause and/or exacerbate race-based health inequities among Black/African American (B/AA) and Indigenous American people. The purpose of this paper is to 1) describe how existing US commercial tobacco regulatory policies may contribute to structural racism and undermine the full benefits of tobacco prevention and control efforts among B/AA and Indigenous American groups; and 2) initiate a call to action for researchers and regulators of tobacco products to examine policies using an equity lens. These actions are imperative if empirically-informed regulation of commercial tobacco products is to address health equity.

The commercial determinants of Indigenous health and well-being: a systematic scoping review

INTRODUCTION

Health inequity within Indigenous populations is widespread and underpinned by colonialism, dispossession and oppression. Social and cultural determinants of Indigenous health and well-being are well described. Despite emerging literature on the commercial determinants of health, the health and well-being impacts of commercial activities for Indigenous populations is not well understood. We aimed to identify, map and synthesise the available evidence on the commercial determinants of Indigenous health and well-being.

METHODS

Five academic databases (MEDLINE Complete, Global Health APAPsycInfo, Environment Complete and Business Source Complete) and grey literature (Australian Indigenous HealthInfoNet, Google Scholar, Google) were systematically searched for articles describing commercial industry activities that may influence health and well-being for Indigenous peoples in high-income countries. Data were extracted by Indigenous and non-Indigenous researchers and narratively synthesised.

RESULTS

56 articles from the USA, Canada, Australia, New Zealand, Norway and Sweden were included, 11 of which were editorials/commentaries. The activities of the extractive (mining), tobacco, food and beverage, pharmaceutical, alcohol and gambling industries were reported to impact Indigenous populations. Forty-six articles reported health-harming commercial practices, including exploitation of Indigenous land, marketing, lobbying and corporate social responsibility activities. Eight articles reported positive commercial industry activities that may reinforce cultural expression, cultural continuity and Indigenous self-determination. Few articles reported Indigenous involvement across the study design and implementation.

CONCLUSION

Commercial industry activities contribute to health and well-being outcomes of Indigenous populations. Actions to reduce the harmful impacts of commercial activities on Indigenous health and well-being and future empirical research on the commercial determinants of Indigenous health, should be Indigenous led or designed in collaboration with Indigenous peoples.

Tobacco Couponing: A Systematic Review of Exposures and Effects on Tobacco Initiation and Cessation

INTRODUCTION

Tobacco couponing continues to be part of contemporary tobacco marketing in the United States. We performed a systematic review of the evidence of tobacco product coupon receipt and redemption to inform regulation.

AIMS AND METHODS

We searched EMBASE OVID and Medline databases for observational (cross-sectional and longitudinal) studies that examined the prevalence of tobacco coupon receipt and coupon redemption across different subpopulations, as well as studies of the association between coupon receipt and redemption with tobacco initiation and cessation at follow-up. We extracted unadjusted and adjusted odds ratios for the associations between coupon exposure (receipt, redemption) and tobacco use outcomes (initiation, cessation) and assessed each studies' potential risk of bias.

RESULTS

Twenty-seven studies met the criteria for inclusion. Of 60 observations extracted, 37 measured coupon receipt, nine measured coupon redemption, eight assessed tobacco use initiation, and six assessed cessation. Tobacco product coupon receipt and redemption tended to be more prevalent among younger adults, women, lower education individuals, members of sexual and gender minorities, and more frequent tobacco users. Coupon receipt at baseline was associated with greater initiation. Coupon receipt and redemption at baseline were associated with lower cessation at follow-up among tobacco users. Results in high-quality studies did not generally differ from all studies.

CONCLUSIONS

Tobacco product coupon receipt and redemption are often more prevalent among price-sensitive subpopulations. Most concerning, our results suggest coupon receipt may be associated with higher tobacco initiation and lower tobacco cessation. Couponing thereby increases the toll of tobacco use and could prove to be a viable public health policy intervention point.

IMPLICATIONS

A systematic review was conducted of the scientific literature about the receipt, redemption, and effects on tobacco initiation and cessation of tobacco product couponing. This review found that tobacco coupons are more often received by price-sensitive persons and these coupons serve to increase tobacco initiation and decrease tobacco cessation. Policy efforts to address these consequences may help curb tobacco's harms and address health inequities.

Project SUN: Pilot Study of a Culturally Adapted Smoking Cessation Curriculum for American Indian Youth

American Indian Alaska Native (AIAN) youth have disproportionately higher rates of commercial tobacco product use compared to other racial and ethnic groups in the U.S. These rates underscore a need for commercial tobacco product cessation interventions that are culturally informed. This project studied the development, implementation, and some impact data of an adapted version of Project EX, an evidence-based intervention for teen smoking cessation. Implementation challenges resulted in a change from a three-arm to a single-arm trial with 37 AIAN youth who participated in an eight-week curriculum. Intent-to-treat analysis with biochemical validation results indicated that 32% (N = 12/37) of youth quit smoking at the three-month follow-up. Participants reported being satisfied with the program overall and enjoying the culturally adapted activities. This study detailed the program's adaptation and lessons learned during implementation.

Racial/ethnic group comparisons of quit ratios and prevalences of cessation-related factors among adults who smoke with a quit attempt

BACKGROUND

Smoking-related disparities exist among racial/ethnic minoritized groups.

OBJECTIVE

We compared quit ratios and smoking cessation-related protective and risk factors by race/ethnicity to inform approaches to reduce disparities.

METHODS

Among adults who smoke with a quit attempt from Wave 4 (2016-2017) Population Assessment of Tobacco Use and Health Study, the following factors were examined by racial/ethnic group (American Indians/Alaska Native [AI/AN;n = 165], Black/African American [AA;n = 526], Asian [n = 38], Hispanic/Latino/Latina/Spanish [n = 475], or White [n = 1,960]), wherein each were nearly gender-balanced: cessation medications, counseling/self-help materials, home smoking ban, social support, e-cigarette use, sleep, and mental health.

RESULTS

Quit ratio was lower for AI/AN (adjusted odds ratio[aOR]:0.61) and Black/AA (aOR:0.49) and higher for Asian (aOR:1.90) and Hispanic/Latino/Latina/Spanish (aOR:1.30) than White adults. Medication use was low among all and lower among Black/AA (aOR:0.70) and Hispanic/Latino/Latina/Spanish (aOR:0.56) than White adults. Use of counseling/self-help materials were low among all and higher in AI/AN (aOR:1.85), Black/AA (aOR:1.87), and Hispanic/Latino/Latina/Spanish (aOR:1.49) than White adults. Presence of a smoking ban was lower among Black/AA (aOR:0.40) and higher in Hispanic/Latino/Latina/Spanish (aOR:1.59) than White adults. E-cigarette use was lower in Black/AA (aOR:0.53) and Hispanic/Latino/Latina/Spanish (aOR:0.43) than White adults. Sadness, anxiety, and sleep difficulties were higher in AI/AN (aORs:1.57, 1.50, 1.64) than White adults.

CONCLUSIONS

All racial/ethnic groups would benefit from policies and programs that increase cessation medications and counseling. Quit ratios were particularly low among Black/AA and AI/AN adults. Black/AA adults may benefit from efforts to increase smoking bans, while AI/AN adults may benefit from cessation approaches that simultaneously target sleep and mental health.

Risk Perceptions of Low Nicotine Cigarettes and Alternative Nicotine Products across Priority Smoking Populations

BACKGROUND

As the U.S. Food and Drug Administration considers a low nicotine product standard for cigarettes, it is important to examine how people who smoke, especially individuals from priority populations disproportionately affected by smoking, perceive low nicotine content (LNC) cigarettes and their relative risk perceptions of alternative nicotine delivery system (ANDS) products, including e-cigarettes and snus, and medicinal nicotine.

METHODS

Data are from Wave 4 (2016-2017) of the adult Population Assessment of Tobacco Use and Health (PATH) Study. We examined respondents' absolute risk perceptions about nicotine, LNC cigarettes, ANDS products and medicinal nicotine; their relative risk perceptions of LNC cigarettes and ANDS products compared to conventional cigarettes; and their relative risk perceptions of medicinal nicotine compared to ANDS products.

RESULTS

The majority of respondents across priority smoking populations indicated snus, e-cigarettes, and LNC cigarettes were 'about the same' level of harmfulness or addictiveness as conventional cigarettes. The majority of respondents indicated e-cigarettes to be 'about the same' harmfulness as medicinal nicotine.

CONCLUSIONS

Our study indicates that adults who smoke cigarettes generally have misperceptions about the harms of nicotine and the relative risks of ANDS products and such misperceptions exist regardless of their racial/ethnic identity, sexual orientation, and gender identity.
