Adolescent cigarette smokers' and non-cigarette smokers' use of alternative tobacco products

Where should I start? A scoping review about the publications on clove cigarettes

INTRODUCTION

The general lack of knowledge about the composition of clove cigarettes and the large number of terms that can be used to define different types of cigarettes that contain cloves makes it difficult to find scientific articles focused on the subject. We reviewed the publications that cited clove cigarettes to assess their relevance.

METHODS

We searched publications on Scopus, ScienceDirect, PubMed, and Portal CAPES during the first semester of 2021, without date restrictions. Through a quality assessment, the studies found were assorted in ten different categories.

RESULTS

Indonesian clove cigarettes-also known as kretek-are a mixture of tobacco and cloves rolled in a cigarette and sprayed with oils, plant extract, and food flavorings, in an unknown quantity and composition, different from each brand, which is usually kept in secret. Due to the relatively low prevalence of use in the general population, most publications on tobacco products tend to ignore clove cigarettes or place them in an existing category. Clove cigarettes can be hand-rolled, machine-made, filtered, unfiltered, and each form can be named differently. The interchangeable use of each term, sometimes grouping conventional cigarettes in the mix, can lead the researcher to consider a publication that should be excluded.

CONCLUSION

The existing regulations on flavored cigarettes, although well-intentioned, are still somewhat vague and broad, leaving possible loopholes that can be exploited by the tobacco industries. Fully understanding the precise effects caused by clove cigarettes can be an important tool in future discussions about tobacco control.

Prevalence of Cigarette Smoking and Associated Factors Among Adolescents in Eastern Ethiopia, 2020

Background

Cigarette smoking is one of the leading causes of preventable morbidity and mortality globally, and it is accountable for many causes of premature deaths. Despite the negative consequences of cigarette smoking, studies to identify factors associated with cigarette smoking are scanty and little is known about this practice in the Somali region so far, so this study aimed to assess the prevalence of cigarette smoking and associated factors among adolescents in the Gode, eastern Ethiopia 2020.

Methods

A community-based cross-sectional study design was employed among 341 adolescents in the Godey administration of the Somali Region, Eastern Ethiopia from July to August 2020. A systematic sampling technique was used to select study participants. Data were collected using a pretested interviewer administered questionnaire. The collected data were entered with Epi-Data version 3.1 and exported to SPSS version 22 software for statistical analysis. Multivariable logistic regression analyses were done to identify the true effect of predictor variables on the outcome variable after controlling for possible confounders. Statistical significance was declared at a p-value < 0.05.

Results

Over all, the prevalence of current cigarette smoking among adolescents was found to be 21.1% (95% CI: (16.7−25.5). Having smoker parents [AOR = 2.57, 95% CI: (1.32–5.02)], whose friends smoke cigarette [AOR = 4.78, 95% CI: (2.12–10.76)], and currently chewing khat [AOR = 6.01, 95% CI: (2.96–12.23)] were significantly associated predictors of current cigarette smoking in the final model of multivariable analysis.

Conclusion

The prevalence of cigarette smoking was relatively high in this study area. This study reported having smokers’ parents, having smokers’ friends and chewing khat were found to be independent predictors for cigarette smoking. Therefore, effective smoking prevention and intervention programs are required in this area.

Patterns of Nicotine and Tobacco Product Use in Youth and Young Adults in the United States, 2011-2015

Introduction

As cigarette smoking has decreased among youth and young adults (YAs) in the United States, the prevalence of other tobacco and nicotine product use has increased.

Methods

This study identified common past 30-day patterns of tobacco and nicotine product use in youth (grades 6–12) and YAs (aged 18–24). Using data from the 2011–2015 National Youth Tobacco Survey (NYTS) and corresponding years of the Truth Initiative Young Adult Cohort Study (TIYAC), past 30-day use of the following products was assessed: cigarettes, e-cigarettes, any type of cigar, smokeless tobacco, hookah, and other tobacco products (pipe, bidis, kreteks, dissolvable tobacco, and snus). A user-generated program in R was used to assess all possible combinations of product-specific and polytobacco use.

Results

The top five patterns of past 30-day use in youth were exclusive cigarette use (12.0%), exclusive cigar use (10.3%), exclusive e-cigarette use (10.0%), dual use of cigarettes and cigars (6.1%), and exclusive hookah use (5.2%). In YAs, the top five patterns were exclusive cigarette use (46.5%), exclusive cigar use (10.0%), dual use of cigarettes and cigars (6.4%), exclusive hookah use (5.9%), and dual use of cigarettes and e-cigarettes (3.9%).

Conclusions

As noncigarette tobacco and nicotine products become increasingly popular among tobacco users, further research is needed to identify predictors and correlates of specific tobacco use patterns in youth and YAs. This analysis can inform tobacco prevention efforts focusing on emerging tobacco products such as e-cigarettes and hookah. Educational and other intervention efforts should focus on the diversity of products and use patterns in these age groups.

Implications

This study uses population-based data to provide new information on the most prevalent patterns of past 30-day nicotine and tobacco use over a 5-year period among youth and young adults. Study findings demonstrate that youth and young adults report using tobacco and nicotine products in different combinations, with varying popularity over time. Additionally, by examining young adults as a separate group, this study highlights the unique patterns of use not previously discussed in the adult literature.

Systematic review of cigars, cigarillos, and little cigars among adolescents: Setting research agenda to inform tobacco control policy

INTRODUCTION

We conducted a systematic review of the literature on cigar research on youth to identify potential future research agenda to generate evidence to inform cigar regulations to prevent cigar use among youth.

METHODS

We searched articles on Medline, EMBASE, and PsycINFO in April 2017 to identify articles relevant to cigars and adolescents. Two independent coders examined 48 articles to determine eligibility: (1) published between 2000-April 2017; (2) published in English; (3) conducted in the United States; (4) published in a peer-review journal; (5) examined cigars, cigarillos, or little cigars; (6) included youth (12-18 years old); and (7) included empirical data. Three independent coders reviewed the included articles (n = 48) to identify whether the studies addressed FDA's Research Priorities.

RESULTS

The studies addressed FDA's Research Priorities of "behavior" (n = 48), "communications" (n = 4), "marketing influences" (n = 1), and "impact analysis" (n = 1). Studies on "behavior" underscored the need for improvements in measurement, such as using brand names and distinguishing cigar products. The review revealed the need for restrictions on cigar flavors, development of media campaigns and interventions, increasing the cost (via taxation), and evaluating the impact of cigar policies.

CONCLUSIONS

The studies mostly focused on surveillance of behaviors and use patterns, which revealed cigar specific issues to address in policies to decrease cigar use among youth. The lack of studies addressing other FDA's research priorities highlighted the critical need for future studies that inform prevention of youth cigar use.

Patterns of alternative tobacco product experimentation among ever smoker adolescents

OBJECTIVES

Alternative tobacco product (ATP) use is popular among adolescents in Western countries, however, little is known about factors influencing ATP experimentation in Europe. The aim of this study was to explore factors associated with ATP experimentation, and to identify patterns of ATP experimentation among Hungarian adolescents who had ever tried manufactured cigarette smoking.

METHODS

Logistic regression analyses were applied to estimate the relationship between individual cigarette smoking experiences, social smoking influences, demographics, and ATP experimentation (roll-your-own (RYO) cigarettes, cigars/cigarillos, waterpipe, traditional pipe and flavoured cigarettes) in a cross-sectional sample of 8th and 11th grade students (N = 1,067, 56.0% of girls) who had ever tried manufactured cigarette smoking in six metropolitan cities of Hungary. Latent class analysis (LCA) was performed to identify patterns of different ATP use.

RESULTS

Almost 90% of the sample had ever tried ATPs and significantly more commonly older (91.8%) versus younger (79.8%) students. Waterpipe was the most popular product to try followed by flavoured cigarettes, cigars/cigarillos, RYO cigarettes, and pipe. Boys were more likely to report ATP experimentation compared to girls. Younger age of cigarette smoking experimentation, greater frequency of past month cigarette smoking and history of ever daily smoking for 30 days showed strong association with ATP experimentation. Students with one or more smoking friends were more vulnerable to experiment with ATPs. Weekly allowance, school academic achievement and household smoking exposure showed no effect on the experimentation. LCA identified four subgroups of ATP experimenters comprising intense polytobacco experimenters (38.4%), mainly waterpipe experimenters (34.2%), moderate polytobacco experimenters (14.9%), and less interested experimenters (12.5%).

CONCLUSION

Tobacco prevention programmes targeting adolescents should emphasize the risks of using ATPs in addition to manufactured cigarettes. Accessibility of ATPs should be better regulated and restrictions should be strongly enforced in order to prevent potential harmful consequences of adolescent polytobacco use.

Exploring the Predictive Validity of the Susceptibility to Smoking Construct for Tobacco Cigarettes, Alternative Tobacco Products, and E-Cigarettes

INTRODUCTION

Within tobacco prevention programming, it is useful to identify youth that are at risk for experimenting with various tobacco products and e-cigarettes. The susceptibility to smoking construct is a simple method to identify never-smoking students that are less committed to remaining smoke-free. However, the predictive validity of this construct has not been tested within the Canadian context or for the use of other tobacco products and e-cigarettes.

METHODS

This study used a large, longitudinal sample of secondary school students that reported never using tobacco cigarettes and noncurrent use of alternative tobacco products or e-cigarettes at baseline in Ontario, Canada. The sensitivity, specificity, and positive and negative predictive values of the susceptibility construct for predicting tobacco cigarette, e-cigarette, cigarillo or little cigar, cigar, hookah, and smokeless tobacco use 1 and 2 years after baseline measurement were calculated.

RESULTS

At baseline, 29.4% of the sample was susceptible to future tobacco product or e-cigarette use. The sensitivity of the construct ranged from 43.2% (smokeless tobacco) to 59.5% (tobacco cigarettes), the specificity ranged from 70.9% (smokeless tobacco) to 75.9% (tobacco cigarettes), and the positive predictive value ranged from 2.6% (smokeless tobacco) to 32.2% (tobacco cigarettes). Similar values were calculated for each measure of the susceptibility construct.

CONCLUSIONS

A significant number of youth that did not currently use tobacco products or e-cigarettes at baseline reported using tobacco products and e-cigarettes over a 2-year follow-up period. The predictive validity of the susceptibility construct was high and the construct can be used to predict other tobacco product and e-cigarette use among youth.

IMPLICATIONS

This study presents the predictive validity of the susceptibility construct for the use of tobacco cigarettes among secondary school students in Ontario, Canada. It also presents a novel use of the susceptibility construct for predicting the use of e-cigarettes, cigarillos or little cigars, cigars, hookah, and smokeless tobacco among secondary school students in Ontario, Canada.

Exclusive and concurrent use of cigarettes and alternative tobacco products among Hong Kong adolescents

INTRODUCTION

The use of alternative tobacco products (ATPs) is becoming increasingly popular among the youth. This study aimed to assess cigarette-only smoking, exclusive ATP use, and concurrent use (cigarettes and ATPs) among adolescents in Hong Kong.

METHODS

We analyzed data of the Hong Kong School-based Survey on Smoking among Students 2012/13 from a representative sample of 45 857 secondary school students. Weighted prevalence of cigarette-only smoking, exclusive ATP use, and concurrent tobacco use were calculated. Multinomial logistic regression examined correlates of exclusive ATP use and concurrent use relative to cigarette-only smoking. Among current (past-30-days) cigarette smokers, multivariable logistic regression assessed whether ATP use was associated with nicotine dependence, quit intention and quit attempt.

RESULTS

Overall, 5.8% of adolescents reported current tobacco use (2.1% cigarette-only smoking, 2.5% exclusive ATP use and 1.2% concurrent use). Compared with cigarette-only smoking, exclusive ATP use and concurrent tobacco use were associated with younger age, higher perceived family financial status, absence of cigarette smoking peers, poor knowledge about smoking and more frequent alcohol use. Among current cigarette smokers, ATP use was negatively associated with cigarette quit intention and quit attempt.

CONCLUSIONS

ATP use was as prevalent as cigarette smoking among adolescents, and ATP users were different from cigarette smokers in many demographic and psychosocial factors. Tobacco control programs among youth should target different types of tobacco users and address all forms of tobacco products.

Youth E-cigarette, Blunt, and Other Tobacco Use Profiles: Does SES Matter?

OBJECTIVE

We examined the associations between socioeconomic status (SES) and adolescent polytobacco use profiles (including e-cigarettes and blunts).

METHODS

Adolescents (N = 1932) completed surveys conducted in 2014 in 3 Connecticut high schools. Within a Latent Class Analysis (LCA) framework, logistic regressions examined associations between SES and polytobacco use profiles comprising never, ever, and current e-cigarette, blunt, cigarette, cigar, cigarillo, hookah, and smokeless tobacco use.

RESULTS

We identified 5 classes: (1) current polytobacco users; (2) ever polytobacco users; (3) current e-cigarette, blunt, and cigarette users; (4) ever e-cigarette and blunt users; and (5) never users. Low SES, relative to high SES, was associated with greater likelihood of being: (1) an ever polytobacco user; (2) a current e-cigarette, blunt, and cigarette user; and (3) an ever e-cigarette and blunt user, relative to a never user.

CONCLUSIONS

Low SES is associated with membership in distinct polytobacco use latent classes. Regulatory initiatives that focus exclusively on cigarette use may miss the opportunity to influence adolescent use of other products, which may be especially relevant to low-income individuals. Future research should examine whether targeting a broader range of products reduces SES-related tobacco use disparities.

Trends and Factors Related to Smokeless Tobacco Use in the United States

BACKGROUND

While 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.

METHODS

We 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.

RESULTS

Decreasing 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.

CONCLUSIONS

Declines 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.

IMPLICATIONS

This 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.

Secondhand hookah smoke: an occupational hazard for hookah bar employees

BACKGROUND

Despite the increasing popularity of hookah bars, there is a lack of research assessing the health effects of hookah smoke among employees. This study investigated indoor air quality in hookah bars and the health effects of secondhand hookah smoke on hookah bar workers.

METHODS

Air samples were collected during the work shift of 10 workers in hookah bars in New York City (NYC). Air measurements of fine particulate matter (PM_2.5), fine black carbon (BC_2.5), carbon monoxide (CO), and nicotine were collected during each work shift. Blood pressure and heart rate, markers of active smoking and secondhand smoke exposure (exhaled CO and saliva cotinine levels), and selected inflammatory cytokines in blood (ineterleukin (IL)-1b, IL-6, IL-8, interferon γ (IFN-γ), tumour necrosis factor (TNF-α)) were assessed in workers immediately prior to and immediately after their work shift.

RESULTS

The PM_2.5 (gravimetric) and BC_2.5 concentrations in indoor air varied greatly among the work shifts with mean levels of 363.8 µg/m³ and 2.2 µg/m³, respectively. The mean CO level was 12.9 ppm with a peak value of 22.5 ppm CO observed in one hookah bar. While heart rate was elevated by 6 bpm after occupational exposure, this change was not statistically significant. Levels of inflammatory cytokines in blood were all increased at postshift compared to preshift testing with IFN-Υ increasing from 0.85 (0.13) to 1.6 (0.25) (mean (standard error of the mean; SEM)) pg/mL (p<0.01). Exhaled CO levels were significantly elevated after the work shift with 2 of 10 workers having values >90 ppm exhaled CO.

CONCLUSIONS

These results demonstrate that hookah bars have elevated concentrations of indoor air pollutants that appear to cause adverse health effects in employees. These data indicate the need for further research and a marked need for better air quality monitoring and policies in such establishments to improve the indoor air quality for workers and patrons.

A Risk-Continuum Categorization of Product Use Among US Youth Tobacco Users

INTRODUCTION

To examine prevalence and correlates of five mutually exclusive tobacco-use patterns among US youth tobacco users.

METHODS

A nationally representative sample of tobacco users (N = 3202, 9-17 years) was classified into five product-use patterns. Weighted multinominal and multivariate logistic regression models were used to examine prevalence of product-use patterns by gender, race and ethnicity, and grade level; and associations between product-use patterns and perceived accessibility of tobacco products, exposure and receptivity to pro-tobacco marketing, social benefits of smoking, and tobacco-associated risks.

RESULTS

Dual use (ie, use of two product categories) was the most prevalent pattern (30.5%), followed by non-cigarette combustible only (26.7%), polytobacco (ie, use of three product categories; 17.5%), cigarette only (14.9%), and noncombustible only (10.4%) use. Product-use patterns differed by gender, race, and ethnicity. Compared to cigarette only users, dual and polytobacco users were more likely to be exposed to and be receptive to pro-tobacco marketing, and were less likely to acknowledge tobacco-use related risks (Ps < .05).

CONCLUSIONS

Curbing tobacco use warrants research on users of more than one tobacco-product categories according to the risk-continuum categorization.

IMPLICATIONS

We present a risk-continuum categorization of product-use patterns among tobacco users not older than 17 years. We classify tobacco users into five mutually exclusive product-use patterns: cigarette only users, non-cigarette combustible only users, noncombustible only users, dual use, and polytobacco use. This categorization overcomes limitations in current literature on tobacco-use patterns, which include exclusion of certain products (eg, e-cigarettes) and product-use patterns (eg, exclusive users of non-cigarette products), and inconsistent classification of tobacco users. It is parsimonious yet complex enough to retain differential characteristics of sub-tobacco users based on number (single, dual, polytobacco) and categories (cigarettes, non-cigarette combustibles, noncombustibles) of tobacco products consumed.

Use of electronic cigarettes and alternative tobacco products among Romanian adolescents

OBJECTIVES

To assess socio-demographic and smoking-related correlates of e-cigarette and alternative tobacco products (ATPs) use in a multi-ethnic group of adolescents in Tîrgu Mures, Romania.

METHODS

The cross-sectional study included 1835 high school students from Tirgu Mures, Romania. Socio-demographic variables and data about smoking and e-cigarettes and ATP use were collected using an online questionnaire. Chi-square tests or one-way ANOVA were applied to compare never smokers, non-current smokers, and current smokers. Multiple logistic regression was conducted to determine the correlates of e-cigarettes and ATP use.

RESULTS

The most frequently tried non-cigarette nicotine and tobacco products were e-cigarette (38.5 %), cigar (31.4 %) and waterpipe (21.1 %). Ever trying and current use of cigarettes were the most important correlates of e-cigarette and ATPs use. Sex, ethnicity, sensation seeking and perceived peer smoking were correlates of several ATPs use.

CONCLUSIONS

The results of this study may inform the development of tailored tobacco control programs.

Cigarette smoking susceptibility among youth alternate tobacco product users: implications of flavoured tobacco from a national cross-sectional Canadian sample (YSS 2012/2013)

OBJECTIVES

Declines in cigarette smoking have been accompanied by increases in alternative tobacco product (ATP) use, particularly among youth. This study examines smoking susceptibility and ATP use in a national sample of Canadian youth.

METHODS

Data from grades 9-12 students who participated in the 2012/2013 Youth Smoking Survey, a nationally generalisable sample of Canadian students (n=27,404) were used to examine cigarette smoking susceptibility among never smokers (n=17,396). Logistic regression models were used to examine differences in smoking susceptibility by use of flavoured and all ATPs and by sociodemographic and lifestyle characteristics.

RESULTS

Overall, 30% of Canadian grades 9-12 never smokers were susceptible to cigarette smoking. Compared to never users, those who had ever tried ATPs (OR=1.96, 95% CI 1.59 to 2.42) and those who had ever tried flavoured ATPs (OR=2.20, 95% CI 1.63 to 2.96) had significantly higher odds of being susceptible to cigarette smoking.

CONCLUSIONS

ATP use is associated with smoking susceptibility among youth never smokers. Findings from this study, along with existing evidence, can be used by policymakers to improve regulation around youth access to ATPs (particularly flavoured varieties).

Characteristics and Patterns of Black & Mild Use Among African American Smokers

INTRODUCTION

Increased consumption of little cigars and cigarillos (LCCs) among late adolescent and young adult African American smokers is an emerging public health concern. Despite a growing body of epidemiological evidence, there is scant research on systematic variations in LCC use among young adult African Americans. This study aimed to disaggregate African American Black & Mild (B&M) smokers and to identify subgroups of cigarillo smokers' behaviors and associated characteristics.

METHODS

Using telephone screening data for a NIH-funded clinical laboratory study of toxicant exposure associated with B&M use, latent class analysis (LCA) was used to classify 331 African American B&M smokers' based on daily use, average daily consumption, preference for flavors, preference for product design tips, and product modification behaviors.

RESULTS

Results showed five classes, three of which (Daily-Hypers, Daily-Flavored, and Heavy-Daily-Hypers) reflected daily use and average daily consumption rate ranging between 2.7 and 8.9 B&M cigarillos per day. Non-Daily-Hypers and Non-Daily-Flavored classes represented non-daily use patterns and averaged less than 1.0 B&M cigarillo per day. Both sets of classes defined by daily users and non-daily users included smokers who preferred flavored tobacco and who practiced product modification techniques involving hyping and blunting.

CONCLUSIONS

Latent class analysis is a useful method to detect subtle differences in B&M product preferences and smoking behaviors among African Americans. Study findings highlight the importance of developing tailored interventions that consider within group differences in order to reduce the prevalence of cigarillo smoking among those with the greatest burden.

IMPLICATIONS

The current study is the first to identify unique subgroups of African American B&M smokers based on cigarillo use behaviors and associated characteristics. Latent class analyses may prove useful for understanding other subgroups of tobacco users. Current findings concerning patterns of LCC use illustrate how future tobacco cessation and prevention interventions may be tailored for African American smokers.

Clinical Practice Policy to Protect Children From Tobacco, Nicotine, and Tobacco Smoke

Tobacco dependence starts in childhood. Tobacco exposure of children is common and causes illness and premature death in children and adults, with adverse effects starting in the womb. There is no safe level of tobacco smoke exposure. Pediatricians should screen for use of tobacco and other nicotine delivery devices and provide anticipatory guidance to prevent smoking initiation and reduce tobacco smoke exposure. Pediatricians need to be aware of the different nicotine delivery systems marketed and available.Parents and caregivers are important sources of children's tobacco smoke exposure. Because tobacco dependence is a severe addiction, to protect children's health, caregiver tobacco dependence treatment should be offered or referral for treatment should be provided (such as referral to the national smoker's quitline at 1-800-QUIT-NOW). If the source of tobacco exposure cannot be eliminated, counseling about reducing exposure to children should be provided.Health care delivery systems should facilitate the effective prevention, identification, and treatment of tobacco dependence in children and adolescents, their parents, and other caregivers. Health care facilities should protect children from tobacco smoke exposure and tobacco promotion. Tobacco dependence prevention and treatment should be part of medical education, with knowledge assessed as part of board certification examinations.

Trends in Multiple Tobacco Product Use, Among High School Students

OBJECTIVE

The purpose of this study was to identify trends of tobacco use, among all students and current tobacco users, in a nationally representative sample of high school students from 1999 to 2013.

METHODS

Trends in individual and concurrent use of cigarettes, cigars, and smokeless tobacco (SLT) products were tested using 8 repeated cross-sections of the YRBS between 1999 and 2013. Tests for effect modification of race/ethnicity and sex were conducted for each trend.

RESULTS

Among all students, there were significant non-linear changes detected for the concurrent use of all 3 products, and the dual use of cigarettes and cigars. Girls significantly increased their use of SLT. Among users, significant changes were detected for each individual product and all combinations. Female users significantly increased their concurrent use of cigarettes and cigars and concurrent use of cigarettes and SLT. Male users significantly decreased their use of cigarettes and cigars.

CONCLUSION

While the decrease in the youth prevalence of cigarette use is a public health success, there is concern about the increase in non-cigarette products, among tobacco users. These changes further drive increases in the concurrent use of tobacco products, adding to the potential health burden.

Trends in use of little cigars or cigarillos and cigarettes among U.S. smokers, 2002-2011

OBJECTIVES

Little cigars and cigarillos may resemble cigarettes, but may be less expensive and can be purchased singly and in flavored varieties. We used two major U.S. surveys to investigate use of cigarillos and cigarettes.

METHODS

The 2010/2011 Tobacco Use Supplement to the Current Population Survey ascertained cigar use by brand and type (little cigars/cigarillos or large/regular). The annual National Survey on Drug Use and Health (NSDUH) assessed cigar use by brand, 2002-2011. We used the available data to classify cigars by type among males in the NSDUH.

RESULTS

Estimated prevalence of little cigar use among male cigar smokers was similar using the two surveys. From 2002 to 2011, past-30-day cigarette smoking declined for all age groups and genders, but among young adult men (aged 18-25) little cigar smoking remained steady at nearly 9%. "Cigarette and/or cigar" smoking was 44% among young adult men in 2011, and was consistently 6 percentage points higher than cigarette-only smoking, from 2002 to 2011. Over 60% of male and 70% of female adolescent/young adult cigar smokers also smoked cigarettes in 2011. Most male adolescents preferred little cigars to traditional cigars. Among males, most lower income or less educated cigar smokers preferred little cigars, compared to only 16% of those with higher education.

CONCLUSIONS

These patterns indicate that little cigar/cigarillo use may promote initiation and maintenance of cigarette smoking, particularly among younger and less advantaged populations. Population-level data are urgently needed to better assess type of cigar smoked and reasons for use.

State-of-the-art office-based interventions to eliminate youth tobacco use: the past decade

Tobacco use and tobacco smoke exposure are among the most important preventable causes of premature disease, disability, and death and therefore constitute a major pediatric health concern. The pediatric primary care setting offers excellent opportunities to prevent tobacco use in youth and to deliver cessation-related treatment to youth and parents who use tobacco. This report updates a "state-of-the-art" article published a decade ago on office-based interventions to address these issues. Since then there has been marked progress in understanding the nature, onset, and trajectories of tobacco use and nicotine addiction in youth with implications for clinical practice. In addition, clinicians need to remain abreast of emerging nicotine delivery systems, such as electronic cigarettes, that may influence uptake or continuation of smoking. Although evidence-based practice guidelines for treating nicotine addiction in youth are not yet available, research continues to build the evidence base toward that goal. In the interim, practical guidelines are available to assist clinicians in addressing nicotine addiction in the pediatric clinical setting. This article reports current practices in addressing tobacco in pediatric primary care settings. It reviews our increasing understanding of youth nicotine addiction, summarizes research efforts on intervention in the past decade and additional research needed going forward, and provides practical guidelines for pediatric health care providers to integrate tobacco use prevention and treatment into their clinical practice. Pediatric providers can and should play an important role in addressing tobacco use and dependence, both in the youth they care for and in parents who use tobacco.

Acute Effects of "Hyping" a Black&Mild Cigarillo

INTRODUCTION

Cigars remain a widely used tobacco product among adolescent and adult populations. The appeal of a certain type of cigar, the cigarillo, may be enhanced by users' beliefs that their harm potential can be reduced by removing the inner tobacco liner before use (a.k.a. "hyping"). The purpose of this within-subject study was to compare the acute effects of smoking an original cigarillo, a modified ("hyped") cigarillo, and an unlit cigarillo.

METHODS

Twenty smokers (19 males, 1 female; 19 non-Hispanic blacks, 1 Hispanic "other") of at least 7 Black&Mild (B&M) cigarillos/week and at most 5 cigarettes/day completed the study. All participants reported hyping their cigarillos at least occasionally. Primary outcomes, assessed over two, 30-minute smoking bouts, included plasma nicotine, expired air carbon monoxide (CO) concentration, subjective ratings (product effects, nicotine abstinence symptoms), and puff topography.

RESULTS

Mean plasma nicotine concentration increased significantly within (pre- to post-bouts), but not between, original and modified B&M conditions. Mean CO concentration was significantly lower for modified, relative to original, B&M smoking at all post-administration timepoints. Both smoked conditions significantly increased ratings of positive product effects (satisfaction, pleasant) and decreased abstinence symptom magnitude; however, ratings generally did not differ between these conditions. Overall, topography outcomes did not differ between modified and original B&M smoking.

CONCLUSIONS

Results are consistent with a previous report in that "hyping" may decrease users' CO, but not nicotine, exposure. While these data collectively suggest reduced exposure to CO acutely with engagement in "hyping," longer-term assessments are needed to determine the impact on individual and public health.

Youth tobacco cessation: quitting intentions and past-year quit attempts

BACKGROUND

Despite declining use of conventional tobacco products, youth use of non-cigarette tobacco has become prevalent; however, quitting behaviors remain largely unexplored.

PURPOSE

To examine nationally representative data on quit intentions and past-year attempts to quit all tobacco use among current youth tobacco users.

METHODS

In 2013, data were analyzed from the 2012 National Youth Tobacco Survey (NYTS). Weighted prevalence estimates of quit intentions and past-year quit attempts for current youth tobacco users are presented.

RESULTS

Prevalence of quit intentions and past-year attempts to quit all tobacco use were 52.8% and 51.5%, respectively, among current youth tobacco users. Among non-mutually exclusive groups, current cigarette smokers had the highest prevalence of quit intentions (56.8%) and past-year quit attempts (52.5%), whereas current hookah users had the lowest prevalence of quit intentions (41.5%) and past-year quit attempts (43.7%). Quit intentions among black, non-Hispanics (65.0%) and Hispanics (60.4%) were significantly higher versus white, non-Hispanics (47.5%). Youth reporting parental advice against tobacco had significantly higher prevalence of quit intentions (56.7%) and past-year quit attempts (55.0%) than those not reporting parental advice. Youth who agreed all tobacco products are dangerous (58.5%) had significantly higher prevalence of quit intentions than those who disagreed (37.0%).

CONCLUSIONS

Continued efforts are needed to better understand youth motivation for quitting all tobacco products. Public health messaging about the dangers of all tobacco and cessation efforts should be aimed at the full range of tobacco products, not just cigarettes, and tailored to meet the needs of youth polytobacco users.

Hookah use among U.S. high school seniors

OBJECTIVES

Prevalence of hookah use is increasing significantly among adolescents. This study aimed to delineate demographic and socioeconomic correlates of hookah use among high school seniors in the United States. We hypothesized that more impoverished adolescents and those who smoked cigarettes would be more likely to use hookahs.

METHODS

Data were examined for 5540 high school seniors in Monitoring the Future (years 2010-2012), an annual nationally representative survey of high school students in the United States. Using data weights provided by Monitoring the Future, we used multivariable binary logistic regression to delineate correlates of hookah use in the last 12 months.

RESULTS

Eighteen percent of students reported hookah use in the past year. Compared with white students, black students were at lower odds for use (adjusted odds ratio [AOR] = 0.27, P < .0001). High parent education increased the odds for use (AOR = 1.58, P < .001), and student weekly income from a job of >$50/week (AOR = 1.26, P < .05) or $11 to $50 per week from other sources (AOR = 1.35, P < .01) also increased odds for use. Males and urban students were also at higher odds for use, as were users of alcohol, marijuana, and other illicit substances. Former cigarette smokers were at higher risk, and current smokers were at highest risk for use.

CONCLUSIONS

Adolescents of higher socioeconomic status appear to be at particularly high risk for hookah use in the United States. Prevention efforts must target this group as prevalence continues to increase.

Experimentation and use of cigarette and other tobacco products among adolescents in the Brazilian state capitals (PeNSE 2012)

INTRODUCTION: Nicotine dependence establishes itself more rapidly among adolescents than among adults. Tobacco occupies the fourth place in the rank of main risk factors for non-communicable diseases in the continent. Studies reveal that other forms of tobacco use have increased among adolescents. METHODS: Were included the 9th grade students from the 26 State Capitals and the Federal District. who were participants of the National Adolescent School-based Health Survey (PeNSE), in 2012. Factors independently associated with experimentation and regular use of cigarettes were investigated by means of multinomial logistic regression, using as reference "never tried a cigarette". The use of other tobacco products included cigar, pipe, narghile and others. RESULTS: Of the in the 61,037 participants in the 26 Brazilian capitals and the Federal District, 22.7% (95%CI 21.7 - 23.5) had experimented cigarettes, 6.1% (95%CI 5.6 - 6.6) are regular smokers and 7.1% (95%CI 6.5 - 7.7) had used other tobacco products, with half of them also being regular smokers. The chances of experimenting and being a regular smoker increased with age and according to the frequency of weekly exposure to other smokers. These chances were also higher among students who worked, who lived in monoparental families or without their parents, and those who felt that their parents would not mind if they smoked. CONCLUSION: Results reinforce the association between social disadvantages and experimenting and regular smoking. In addition, the use of other tobacco products is worthy of attention and may lead to regular smoking.

The changing face of tobacco use among United States youth

Tobacco use, primarily in the form of cigarettes, is the leading cause of preventable morbidity and mortality in the United States (U.S.). The adverse effects of tobacco use began to be recognized in the 1940's and new hazards of active smoking and secondhand smoke (SHS) exposure from cigarettes continue to be identified to this day. This has led to a sustained and wide-ranging array of highly effective regulatory, public health, and clinical efforts that have been informed by extensive scientific data, resulting in marked decreases in the use of cigarettes. Unfortunately, the dramatic recent decline in cigarette use in the U.S., has been accompanied by an upsurge in adolescent and young adult use of new, non-cigarette tobacco and nicotine-delivery products, commonly referred to as alternative tobacco products (ATPs). Commonly used ATPs include hookah, cigars, smokeless tobacco, and electronic cigarettes. While there have been a number of review articles that focus on adult ATP use, the purpose of this review is to provide an overview of what is, and is not known about emerging ATP use among U.S. adolescents on a national scale; as well as to identify research gaps in knowledge, and discuss future health and policy needs for this growing public health concern. This paper is not meant to systemically review all published survey data, but to present clear depiction of selected ATP usage in youth populations using national survey data.

Association of smokeless tobacco use and smoking in adolescents in the United States: an analysis of data from the Youth Risk Behavior Surveillance System survey, 2011

BACKGROUND

Using smokeless tobacco and smoking are behaviors that increase the risk of developing oral cancer, soft-tissue lesions, caries, periodontal disease and other oral conditions. The author conducted a study to examine use of smokeless tobacco and smoking by adolescents.

METHODS

The study was a cross-sectional analysis of participants with complete data regarding smoking, smokeless tobacco use and other variables of interest from the 2011 national Youth Risk Behavior Surveillance System survey (n = 9,655). The author performed descriptive analysis and multivariable logistic regression analyses.

RESULTS

The unadjusted odds ratio for smokeless tobacco use and smoking was 9.68 (95 percent confidence interval [CI], 7.72-12.13; P < .0001), and the adjusted odds ratio was 3.92 (95 percent CI, 2.89-5.31; P < .0001). Adolescents who used smokeless tobacco were more likely to be male, to smoke and to have engaged in binge drinking.

CONCLUSION

Adolescents who were using smokeless tobacco were more likely to be engaging in concomitant smoking and to be participating in other risk-taking behaviors. Practical Implications. Dentists are involved in helping patients with tobacco-use cessation. The association of smoking with using smokeless tobacco needs to be considered in the design of tobacco-use cessation programs for adolescents.
