Smokeless tobacco use in the United States military: a systematic review.

ABSTRACT:

Introduction

Smokeless tobacco (ST) use represents an important target for intervention in the U.S. military population because it impairs "military readiness" and harms the health of the military. This paper aims to provide a systematic review of ST studies conducted in the U.S. military population in order to assess the content of existing ST research in this population, provide estimates of prevalence and clinically relevant use patterns, and discuss how these findings might be used to guide future ST research among this population.

Methods

We reviewed articles published through December 2010 using PubMed and PsycINFO databases, Google Scholar, and any relevant articles' reference lists. Inclusion criteria included focus on a U.S. military sample, English language, measured tobacco use, and ST prevalence was reported or could be calculated. To the extent possible, each article was coded for demographics, socioeconomic status, prevalence, amount, frequency, and length of use, and quit intentions/attempts.

Results

Thirty-nine articles met criteria for inclusion. Less than half focused primarily on ST use among military personnel. The remaining studies measured ST use in the context of other behaviors. Findings related to clinically relevant behaviors included a need for more cohort and intervention studies, a better understanding of ST use in combination with cigarettes (i.e., concurrent use), and identifying risk factors for ST initiation and use.

Discussion

ST use is prevalent among military personnel, as is concurrent use of cigarettes and ST. We provide a number of recommendations to guide future research in this important, yet understudied, area.

Project description:BackgroundWhile declines in smoking prevalence in the United States have been well documented, trends in smokeless tobacco (SLT) use are less clear. This study updates previous analyses of US SLT use prevalence to better understand trends and factors related to SLT use.MethodsWe used the Tobacco Use Supplement of the Current Population Survey (TUS-CPS) to examine trends and factors related to SLT use using joinpoint and logistic regression models. SLT consumption from 1985 to 2011 was obtained from the 2011 Federal Trade Commission Smokeless Tobacco Report. Sensitivity analyses were conducted for assessing the impact of varying frequency definitions of SLT use.ResultsDecreasing trends in smoking and SLT prevalence overall were observed from 1992 to 2003 independently of use definition. SLT prevalence in the total adult population significantly decreased at an annual percent change (APC) of 4.5% per year from 1992 to 2003, but has been approximately constant ever since. Similar patterns were also found in adult males (APC = -4.4%) and young males (APC = -9.5%). SLT per capita consumption decreased significantly from 1991 to 1999 (APC = -2.2%), but has since decreased at only 0.35% per year (1999-2011). SLT use was found to be associated with former smoker status, younger age, white race, living in rural areas, residence in the South, lower education and unemployment, adjusting for other factors.ConclusionsDeclines in SLT use were found in the United States, suggesting tobacco control has had positive impacts, but these have slowed since 2003. Targeting tobacco control policies to at-risk demographic groups is needed to further reduce SLT use in the United States.ImplicationsThis study confirms that the declines in SLT use prevalence stopped in 2003 across different demographic groups, consistent with trends in SLT consumption. In addition, the longer period of analysis in comparison with earlier studies allows for quantitative characterization of SLT use trends using joinpoint regression. The study also shows the impact of different SLT use definitions in determining tobacco product use prevalence and trends.

Project description:IntroductionSmokeless tobacco (ST) was consumed by 356 million people globally in 2017. Recent evidence shows that ST consumption is responsible for an estimated 652 494 all-cause deaths across the globe annually. The WHO Framework Convention on Tobacco Control (FCTC) was negotiated in 2003 and ratified in 2005 to implement effective tobacco control measures. While the policy measures enacted through various tobacco control laws have been effective in reducing the incidence and prevalence of smoking, the impact of ST-related policies (within WHO FCTC and beyond) on ST use is under-researched and not collated.Methods and analysisA systematic review will be conducted to collate all available ST-related policies implemented across various countries and assess their impact on ST use. The following databases will be searched: Medline, EMBASE, PsycINFO, Cumulative Index to Nursing and Allied Health Literature, Scopus, EconLit, ISI Web of Science, Cochrane Library (CENTRAL), African Index Medicus, LILACS, Scientific Electronic Library Online, Index Medicus for the Eastern Mediterranean Region, Index Medicus for South-East Asia Region, Western Pacific Region Index Medicus and WHO Library Database, as well as Google search engine and country-specific government websites. All ST-related policy documents (FCTC and non-FCTC) will be included. Results will be limited to literature published since 2005 in English and regional languages (Bengali, Hindi and Urdu). Two reviewers will independently employ two-stage screening to determine inclusion. The Effective Public Health Practice Project's 'Quality Assessment Tool for Quantitative Studies' will be used to record ratings of quality and risk of bias among studies selected for inclusion. Data will be extracted using a standardised form. Meta-analysis and narrative synthesis will be used.Ethics and disseminationPermission for ethics exemption of the review was obtained from the Centre for Chronic Disease Control's Institutional Ethics Committee, India (CCDC_IEC_06_2020; dated 16 April 2020). The results will be disseminated through publications in a peer-reviewed journal and will be presented in national and international conferences.Prospero registration numberCRD42020191946.

Project description:IntroductionApproximately the same percentage of male high school students in the United States currently uses conventional smokeless tobacco as smokes cigarettes, resulting in toxin exposure.MethodsThis study assessed tobacco product use (smokeless, combustible, and electronic cigarettes) and nicotine and carcinogen exposures in a sample of 594 male rural high school baseball players-a population traditionally at risk for smokeless tobacco use. Salivary specimens were assayed for cotinine (a biomarker of nicotine exposure) and urine specimens for 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol (NNAL, a biomarker of the carcinogen 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK) using liquid chromatography-tandem mass spectrometry.ResultsThe prevalence of past 30-day use of any tobacco product was 29%. Past 7-day smokeless tobacco use (prevalence: 13%) was associated with the highest levels of cotinine and NNAL observed in the sample, whether smokeless tobacco was used exclusively (geometric means: cotinine 11.1 ng/mL; NNAL 31.9 pg/mg-creatinine) or in combination with combustible products (geometric means: cotinine 31.6 ng/mL; NNAL 50.0 pg/mg creatinine). Cotinine and NNAL levels were incrementally higher in each increasing category of smokeless tobacco use frequency. However, observed levels were lower than previously reported for adults, likely reflecting less smokeless use per day among adolescents.ConclusionsBased on these biomarker observations, adolescents who use conventional smokeless tobacco products are exposed to substantial levels of nicotine and NNK. Although exposed to lower levels than adult smokeless users, the findings are concerning given the young age of the sample and tendency for smokeless tobacco users to increase use intensity over time.ImplicationsThis study demonstrates that adolescents using smokeless tobacco are exposed to levels of nicotine and NNK that increase with use frequency and that exceed exposures among peers using other tobacco products. Youth smokeless tobacco use in the United States has not declined along with youth smoking prevalence, giving greater importance to this health concern. To reduce youth (and adult) exposures, needed actions include effective smokeless tobacco use prevention, potentially in combination with reducing the levels of harmful and potentially harmful chemicals in smokeless tobacco products currently popular among adolescents.

Project description:IntroductionThe smokeless tobacco (SLT) industry in the U.S. continues to transform with novel products amid an evolving regulatory environment. We report SLT sales trends in the U.S. by analyzing retail market scanner data from 2011 through 2019.MethodsNational SLT sales data were obtained from Nielsen's Convenience Track System for January 2011 to December 2019. UPC codes were used to classify products by attributes including type, parent company, brand, form, and flavor. Market share was calculated as percentage of total unit sales. Detailed product analysis was presented for moist snuff, snus, and tobacco-free nicotine products.ResultsSLT sales increased by 5.8% between 2011 and 2016 but declined by 3.9% from 2016 to 2019. Moist snuff sales increased by 8.1% between 2011 and 2016 and then declined 7.4% from 2016 to 2019 but still accounted for roughly 90% of the overall market annually. Between 2011 and 2019, snus sales consistently increased while sales of chew, dry snuff, and dissolvables decreased. Tobacco-free nicotine products emerged in 2016 and captured 4.0% of the market by 2019. Portion pouch packaging and flavors showed consistent growth although their popularity varied by the type of smokeless product.ConclusionThis study extends our previous work on U.S. SLT market trends through 2019. Overall sales increased between 2011 and 2016 but there were signs of leveling off including declining sales of moist snuff. Newer products continue to gain market share. Continued monitoring of SLT sales is needed, particularly given the new modified risk status of several products.ImplicationsThis study analyzed the last 9 years of smokeless tobacco market data (2011-2019) to describe recent trends in sales. Overall, the smokeless product category is quite resilient although signs suggest downward trends among some product categories and features. New types of smokeless tobacco products (eg, snus and tobacco-free nicotine pouches) account for a growing share of the market.

Project description:BackgroundOral nicotine pouches (NPs) that contain nicotine but no tobacco leaves are rapidly gaining popularity. However, there is limited research on NPs, including within priority populations. In the current study, we examined awareness of, susceptibility to, and use of NPs in young adults as well as comparative risk perceptions with smokeless tobacco.MethodsIn 2021, 609 young adults (18-25 years) completed an online survey. Participants reported on NP awareness, susceptibility, and use as well as on comparative product perceptions for NPs versus smokeless tobacco. We ran unadjusted between-groups comparisons and an adjusted multinomial logistic regression to identify relationships between product perceptions and NP susceptibility and use.Results41.5% of participants had heard of NPs before. Participants were non-susceptible (66.2%), susceptible (23.5%), or had used NPs (10.3%). Comparative product perceptions between NPs and smokeless tobacco suggested that young adults, as a whole, expressed uncertainty about the relative risk/benefit of using NPs versus smokeless tobacco. However, as expected, unadjusted and adjusted findings indicated that favorable perceptions of NPs versus smokeless tobacco were disproportionately observed among susceptible participants and NP users compared to non-susceptible individuals. Demographic differences were also observed (e.g., NP users were more likely than non-susceptible and susceptible individuals to have used smokeless tobacco).ConclusionsYoung adults reported awareness of, susceptibility to, and use of NPs, with findings indicating that favorable perceptions of NPs versus smokeless tobacco may contribute to NP susceptibility and use beyond known correlates like smokeless tobacco use. However, further research is needed to understand the full range of factors that are associated with NP susceptibility and use. It will be important to disentangle factors that are associated with potential positive public health impacts (e.g., switching from smokeless tobacco to exclusive NP use) from those associated with negative public health impacts (e.g., initiation among nicotine naïve individuals).

Project description:IntroductionSmokeless tobacco (SLT) use in the United States has remained constant or even increased slightly in recent years, whereas smoking has continuously decreased. Characterization of transitions between tobacco products is critical to understand the reasons behind the continuing use of smokeless tobacco.MethodsTwo longitudinal cohorts of Tobacco Use Supplement of the Current Population Survey (TUS-CPS), 2002-2003 (n = 14996) and 2010-2011 (n = 18226), were used to examine transitions between cigarette and SLT use over 1-year periods. Weighted population percentages of four use categories (exclusive cigarette use, exclusive SLT use, dual use, and neither) were calculated for different demographic groups. Transition between use categories and quit rates by product were calculated for each cohort.ResultsRelative to 2002-2003, smoking quit rates of male exclusive smokers significantly increased in 2010-2011 (11.6% vs. 24.4%, p < .0001), but the corresponding SLT use quit rates remained stable (41.3% vs. 40.0%, p = .87). Similar patterns were found in females with smoking quit rates increasing considerably (12.3% vs. 24.2%, p < .0001). Smoking quit rates increased in most sociodemographic groups analyzed. Male SLT use quit rates were significantly lower in SLT exclusive users than in dual users in the 2010-2011 cohort (40.0% vs. 62.2%; p = .04), but smoking quit rates in exclusive smokers and in dual users were roughly equivalent (24.4% vs. 29.5%, p = .68).ConclusionsAlthough smoking quit rates doubled overall and increased in most sociodemographic groups, SLT quit rates remained constant with little transition between products. Longer-term prospective data examining polytobacco use are needed to better understand transitions between tobacco products.ImplicationsThis study uses two longitudinal surveys to investigate changes in switching behaviors between tobacco products. We found that quit rates of self-reported smoking doubled between 2002-2003 and 2010-2011 in most sociodemographic groups in the United States, whereas in contrast quit rates of self-reported Smokeless Tobacco (SLT) use remained roughly constant. This explains in part the opposing trends of tobacco use by product in the United States, with smoking continuing its decrease, whereas SLT use remains constant. Moreover, smokers were unlikely to switch to other forms of tobacco compared to SLT users. Lastly, smoking cessation for dual users was not significantly different from that of exclusive smokers. Understanding transitions between smoking and SLT use is critical to assess the potential long-term impact of SLT use, and potentially that of other alternative tobacco products, on tobacco-related health outcomes.
