Prevalence of heated tobacco product use in Japan: the 2020 JASTIS study. Tob Control 2022; 31:e64-e65. [PMID: 33707176 DOI: 10.1136/tobaccocontrol-2020-056257] [Citation(s) in RCA: 16] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2020] [Revised: 01/04/2021] [Accepted: 02/03/2021] [Indexed: 11/04/2022]
Abstract
BACKGROUND Japan is the leading market for heated tobacco products (HTPs). We assessed the latest prevalence of HTP use including novel products (Ploom S, glo sens, and Pulze). METHODS Data were obtained from an internet-based, self-reported survey conducted during February-March 2020 with individuals aged 15-74 years in Japan(n=9044). Prevalence of current (past 30-day) HTP use and cigarette smoking was computed. Poison regression analysis was conducted to examine predictors of HTP use among current cigarette smokers (n=1478). All analyses were weighted to account for selection bias in the internet survey using a nationally representative sample of Japanese population. RESULTS In 2020, prevalence of current HTP use and cigarette smoking was 10.9% and 25.9% in Japan, respectively. The most commonly used HTP brand was IQOS (5.7%) followed by Ploom TECH/Ploom TECH+ (5.4%) and glo (2.6%). Use of Ploom S, glo sens and Pulze was 1.6%, 0.8% and 0.6%, respectively. Among current cigarette smokers, 34.9% of those who were interested in quitting smoking and 30.5% of those who were not interested in quitting reported concurrent use of HTP, respectively (difference not significant). Cigarette smokers who reported having multiple chronic conditions (aPR=2.31), alcohol consumption (aPR=2.07), and e-cigarette use (aPR=1.88) were more likely to use an HTP compared to those who did not report such characteristics. CONCLUSIONS HTP use remained prevalent in Japan. One in three current cigarette smokers used HTPs regardless of whether they were interested inquitting smoking. Continuedsurveillance is important to inform national and global tobaccocontrol strategies.

Use of Multiple Tobacco and Tobacco-Like Products Including Heated Tobacco and E-Cigarettes in Japan: A Cross-Sectional Assessment of the 2017 JASTIS Study. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:ijerph17062161. [PMID: 32213924 PMCID: PMC7143444 DOI: 10.3390/ijerph17062161] [Citation(s) in RCA: 14] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/19/2020] [Revised: 03/20/2020] [Accepted: 03/21/2020] [Indexed: 12/18/2022]
Abstract
Information on the use of multiple tobacco and tobacco-like products (hereafter multiple tobacco products use, i.e., use of more than one product) is important for tobacco control. Use of heated tobacco products (HTPs), which first became popular in Japan, has been spreading over the world, while information about use of multiple tobacco products, including HTPs, is insufficient. We analyzed data of 10,114 responders from the 2017 Japan "Society and New Tobacco" Internet Survey (JASTIS) study. The prevalence and adjusted odds ratio (aOR) of multiple tobacco products use were estimated with inverse probability weighting using multivariable logistic regression models to approximate the results to whole Japanese estimates. Tobacco and tobacco-like products included cigarettes, cigars, e-cigarettes, HTPs, pipes/water pipes, and smokeless tobacco products. Among Japanese adults, 18.4% were single tobacco product users and 3.2% were multiple tobacco product users in 2017. Among current product users (100%), cigarettes were the most popular product in single (78.8%) and multiple (14.2%) tobacco products use, while HTPs were the second most popular product in single (5.2%) and multiple (10.6%) tobacco products use. People with no perception of risk regarding e-cigarettes/HTPs were more likely to use multiple tobacco products (aOR = 1.47, 95% CI = 1.12-1.92) than those who perceived a risk. Prevalence rates and predictors of multiple tobacco products use, including HTPs, were studied first. In multiple tobacco products use, high popularity of HTPs among current product users was revealed. Risk perception of e-cigarettes/HTPs was associated with multiple tobacco products use. This study provides baseline information on multiple tobacco products use in Japan, which will enable the examination of trends in the future.

Abstract
BACKGROUND Cross-sectional data suggests that adolescents' receptivity to the advertising of smokeless tobacco is correlated with use of chewing tobacco or snuff. Lack of longitudinal data has precluded determination of whether advertising receptivity precedes or follows initiation of smokeless tobacco. OBJECTIVES The objective of this study was to test for the association between advertising receptivity and subsequent initiation of smokeless tobacco among adolescent males. METHODS Adolescent males from the 1993-1999 Teen Longitudinal California Tobacco Survey were selected at the baseline survey for never having used smokeless tobacco. Separate longitudinal analyses corresponded to two dependent variables, ever use of smokeless tobacco (1993-1996; N = 1,388) and use on 20 or more occasions (1993-1999; N = 1,014). Models were adjusted for demographic variables, risk factors for smokeless tobacco use, and exposure to users of smokeless tobacco. RESULTS Advertising receptivity at baseline was predictive of ever use by late adolescence (RR(95% CI) = 2.0 (1.5, 2.8)) and regular use by young adulthood (RR(95% CI) = 3.7 (2.1, 6.7)) in models that were adjusted for covariates. Conclusions/ Importance: The findings challenge the tobacco industry's assertion that tobacco marketing does not impact youth initiation. This is particularly relevant to tobacco control in the United States because the 2009 Tobacco Control Act places fewer restrictions on smokeless tobacco products compared to cigarettes.

Non-cigarette tobacco and poly-tobacco use among persons living with HIV drawn from a nationally representative sample. Drug Alcohol Depend 2016; 162:251-5. [PMID: 27049581 PMCID: PMC4834032 DOI: 10.1016/j.drugalcdep.2016.03.020] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/06/2016] [Revised: 03/22/2016] [Accepted: 03/24/2016] [Indexed: 02/02/2023]
Abstract
INTRODUCTION Smoking is more prevalent among persons living with HIV (PLWH) than the general population. Little is known about the prevalence of non-cigarette tobacco and poly-tobacco use (PTU; using multiple tobacco products) among this population, which, in the general population is associated with poor health and cessation outcomes. We aimed to characterize the prevalence of cigarette and non-cigarette tobacco use, PTU, and correlates of tobacco use status among a nationally-representative sample of PLWH. METHODS Data came from 472 HIV-positive adults from the 2005-2013 National Survey on Drug Use and Health (NSDUH). RESULTS The prevalence of PTU overall was 8.7% (95% CI=5.6-13.2), and 16.6% (95% CI=10.2-25.7) among past-year tobacco users. In multinomial logistic regression analyses, participants with a high school education or greater (aRRR=2.03, 95% CI=1.03-4.00) were more likely to be non-tobacco users than single product users. Past year drug users (aRRR=0.35, 95% CI=0.19-0.66) and past month binge drinkers (aRRR=0.24, 95% CI=0.12-0.50) were less likely to be non-tobacco users than single product users. Compared to 18-25 year olds, individuals age 26-34 (aRRR=0.13, 95% CI=0.03-0.65) and 35+ (aRRR=0.24, 95% CI=0.09-0.63), and with lifetime anxiety disorder(s) (aRRR=0.18, 95% CI=0.06-0.57) were less likely to be PTUs as compared to single product users. Individuals who reported liking to test themselves by doing risky things were more likely to be PTUs than single product users (aRRR=2.95, 95% CI=1.27-6.84). CONCLUSIONS PTU was slightly higher than in the general population, and should be taken into account when developing cessation interventions tailored to tobacco users living with HIV.

Polytobacco Use of Cigarettes, Cigars, Chewing Tobacco, and Snuff Among US Adults. Nicotine Tob Res 2015; 18:817-26. [PMID: 26136525 DOI: 10.1093/ntr/ntv147] [Citation(s) in RCA: 54] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2015] [Accepted: 06/26/2015] [Indexed: 01/31/2023]
Abstract
INTRODUCTION Tobacco use prevalence has been commonly estimated on a product by product basis and the extent of polytobacco use among current users of each tobacco product is not well understood. This study aimed to examine the prevalence, trends, and correlates of polytobacco use among current users of cigarettes, cigars, chewing tobacco, and snuff in US adults aged ≥18. METHODS We used pooled data from the 1998, 2000, 2005, and 2010 Cancer Control Supplements of the National Health Interview Survey (N = 123 399 adults). Multivariate logistic regression models were estimated to determine significant factors associated with polytobacco use. RESULTS In 2010, the prevalence of polytobacco use was 8.6% among current cigarette smokers, 50.3% among current cigar users, 54.8% among current chewing tobacco users, and 42.5% among current snuff users. After controlling for other covariates, gender and race/ethnicity did not show consistent associations with poly-use across these four groups of current tobacco users; however, a positive association of young adulthood, less than high school education, and binge drinking with poly-use was consistently found among all these groups. CONCLUSIONS Polytobacco use is extremely popular among current users of non-cigarette tobacco products. Polytobacco use patterns differ across sociodemographic subpopulations, and the gender and racial/ethnic profiles in poly-users vary across different groups of current tobacco users. Tobacco control strategies need to consider the interrelationships in the use of different tobacco products and the diverse profiles of poly-users in order to develop tailored tobacco prevention and intervention policies to further reduce the burden of tobacco use.

Tobacco use pattern among a national firefighter cohort. Nicotine Tob Res 2015; 17:66-73. [PMID: 25145378 PMCID: PMC4832966 DOI: 10.1093/ntr/ntu131] [Citation(s) in RCA: 22] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2014] [Accepted: 06/28/2014] [Indexed: 02/06/2023]
Abstract
INTRODUCTION To date, there have been no large-scale, national epidemiological studies of tobacco use patterns among firefighters, particularly with a focus on smokeless tobacco (SLT) and dual use with cigarettes. While rates of firefighters' smoking are relatively low compared to the general population, SLT use typically is substantially higher than the populations they protect. In the current study, we systemically examine tobacco use, including SLT and dual use, and the health-related profiles of various tobacco use groups in a national sample of career firefighters. METHODS Data are from a national cohort study of career departments (N = 20) comprised of 947 male firefighters. RESULTS Among 947 participants, 197 (21%) were tobacco users, of which, 34.5% used cigarettes, 53.2% used SLT, and 12.2% used both cigarettes and SLT. Adjusted rates of smoking, SLT use, and dual use were 13.2%, 10.5%, and 12.2%, respectively. Tobacco users of all types were significantly younger and had served fewer years in fire service and were significantly more likely to engage in heavy and binge drinking, as well as more likely to show signs of depressive symptoms compared to nontobacco users. CONCLUSIONS Detailed information on tobacco use pattern will aid in better understanding what factors are contributing to the high rates of SLT and dual use among firefighters in order to guide and develop an appropriate treatment program for the fire service.

Abstract
AIMS To examine the associations between youth poly-tobacco use and substance use disorders. DESIGN Analysis of data from the 2007-11 US National Survey on Drug Use and Health. SETTING Randomly selected, household-dwelling adolescents from the non-institutionalized, civilian population of the United States. PARTICIPANTS A total of 91 152 adolescents (aged 12-17 years). METHODS Logistic regression models were used to examine the associations between type of tobacco user (non-user, users of alternative tobacco products only, users of cigarettes only and users of cigarettes plus alternative tobacco products) with past year alcohol, marijuana or other illicit drug use disorders, adjusting for demographic and social variables. FINDINGS Compared with non-users of tobacco, the greatest risk for substance use disorders was among users of cigarettes plus alternative tobacco products [alcohol disorder adjusted odds ratio (aOR) = 18.3, 95% confidence interval (CI) = 16.2-20.6; marijuana disorder aOR = 37.2, 95% CI = 32.5-42.7; other drug disorder aOR = 18.4, 95% CI = 15.4-21.8], followed by users of cigarettes only (alcohol disorder aOR = 9.6, 95% CI = 8.8-10.6; marijuana disorder aOR = 20.4, 95% CI = 18.1-23.0; other drug disorder aOR = 9.4, 95% CI = 7.8-11.4), then users of alternative tobacco products only (alcohol disorder aOR = 8.1, 95% CI = 6.7-9.6; marijuana disorder aOR = 9.2, 95% CI = 7.5-11.4; other drug disorder aOR = 3.2, 95% CI = 2.4-4.3). CONCLUSIONS Tobacco use in adolescence is associated with higher rates of substance use disorders across all tobacco users, especially among those who use cigarettes plus other tobacco products.

Abstract
BACKGROUND Few studies have examined the patterns and correlates of polytobacco use among a large, nationally representative population over an extended period of time. METHODS This study examined 10years of data from the National Survey on Drug Use and Health (NSDUH) to establish time trends and correlates for exclusive and mixed use of cigarettes, smokeless tobacco (SLT), cigars, and pipes. RESULTS Results show that rates of polytobacco use were essentially unchanged from 2002 to 2011 (8.7% to 7.4%), though some product combinations, including cigarettes and SLT, cigars and SLT, and use of more than two products have increased. In tobacco users under age 26, the proportion of polytobacco use increased, even as overall tobacco use declined. The factors associated with polytobacco use among tobacco users included sex, income, education, risk taking/seeking behaviors, and outward indicators of 'risk-liability'. CONCLUSIONS Findings provide a snapshot of trends of single and polytobacco product use as well as trends in combinations of product use. Longitudinal studies are needed to examine the sequence of individual patterns of tobacco product use and to identify whether polytobacco use results in greater nicotine dependence, increased exposure to harmful and potentially harmful constituents and/or greater risk of tobacco related disease.

Abstract
INTRODUCTION Poly-tobacco use is defined as cigarette and other tobacco consumption with either product used daily or nondaily. While concurrent use of different types of tobacco has been documented within the general population, less is known about poly-tobacco use among HIV-positive smokers and its impact on smoking cessation efforts. OBJECTIVE To characterize the profile of poly-tobacco users (PTU) in a sample of HIV-positive smokers participating in a cessation program. METHODS The study sample consisted of 474 HIV-positive smokers enrolled in a 2-group randomized controlled trial of cigarette smoking cessation comparing a cell phone-based intervention to usual care. Prevalence was determined, and risk factors for poly-tobacco use were evaluated using logistic regression. RESULTS In this cohort of HIV-positive cigarette smokers, 21.6% of participants were PTU, with cigars (73.4%) the most common tobacco product consumed. Among PTU, 73.5% used other form(s) of tobacco some days, and 26.5% use them every day. Perceived discrimination and unemployment were significantly associated with poly-tobacco use after adjusting for other demographic, behavioral, and psychosocial factors. Analysis showed that participants in the cell phone group (vs. usual care) were more likely to report 24-hr abstinence, both among monocigarette users (16.6% vs. 6.3%, p < .001) and PTU (18.5% vs. 0%, p < .001). CONCLUSION Poly-tobacco use prevalence among adult HIV-positive smokers was considerably higher than in the general population. Special attention must be placed on concurrent use of cigarettes and cigars among HIV-positive smokers. Because PTU are a unique population less likely to succeed in brief smoking cessation interventions, effective cessation programs are needed.

Abstract
BACKGROUND United States Army combat engineer (ENG) training is an intense 14-week course designed to introduce new recruits to basic soldiering activities, Army values and lifestyle, and engineering skills and knowledge. The present investigation examined injury rates and injury risk factors in ENG training. METHODS At the start of their training, 1,633 male ENG recruits were administered a questionnaire containing items on date of birth, height, weight, tobacco use, prior physical activity, and injury history. Injuries during training were obtained from electronic medical records and the training units provided data on student graduation and attrition. Risk factors were identified using Cox regression. RESULTS Ninety-two percent of the recruits successfully graduated from the course and 47% of the recruits experienced one or more injuries during training. Univariate Cox regression demonstrated that recruits were at higher injury risk if they reported that they were older, had a higher or lower body mass index, had smoked in the past, had performed less exercise (aerobic or muscle strength) or sports prior to ENG training, had experienced a previous time-loss lower limb injury (especially if they had not totally recovered from that injury), or had a lower educational level. CONCLUSIONS The present investigation was the first to identify injury rates and identify specific factors increasing injury risk during ENG training. The identified risk factors provide a basis for recommending future prevention strategies.

Abstract
BACKGROUND United States Army military police (MP) training is a 19-week course designed to introduce new recruits to basic soldiering skills, Army values and lifestyle, and law enforcement skills and knowledge. The present investigation examined injury rates and injury risk factors in MP training. METHODS At the start of training, 1,838 male and 553 female MP recruits were administered a questionnaire containing items on date of birth, height, weight, tobacco use, prior physical activity, injury history, and menstrual history. Injuries during training were obtained from electronic medical records and the training units provided data on student graduation and attrition. RESULTS Successfully graduating from the course were 94.3% of the men and 83.7% of the women. Experiencing at least one injury during training were 34.2% of the men and 66.7% of the women (risk ratio (women/men) = 1.95, 95% confidence interval = 1.79-2.13). Recruits were at higher injury risk if they reported that they were older, had smoked in the past, or had performed less frequent exercise or sports prior to MP training. Men were at higher injury risk if they reported a prior injury and women were at higher risk if they reported missing at least six menstrual cycles in the last year or had previously been pregnant. CONCLUSION The present investigation was the first to identify injury rates and identify specific factors increasing injury risk during MP training.

Abstract
BACKGROUND The current study describes concurrent use of cigarettes and smokeless tobacco (CiST) among males and females and evaluates factors associated with CiST use. METHODS Cross-sectional data were drawn from the 2010 Behavioral Risk Factor Surveillance System (BRFSS). Weighted stratified analyses were performed to find associations between CiST use and sociodemographic factors by gender. CiST users were compared to three different tobacco use groups: nonusers, exclusive smokers, and exclusive ST users. RESULTS Younger age and heavy alcohol consumption were consistently associated with increased odds of CiST use among both males and females, and regardless of comparison group. Among males, education was inversely related to CiST use, and these findings were consistent in all three comparisons. Among women, those unable to work or out of work were more likely to be CiST users, which was consistent across comparisons. American Indian females had higher odds of CiST use than White females when nontobacco users or smokers were the comparison group. CONCLUSION This study identified sociodemographic characteristics associated with CiST use, and differences in these associations among women and men. Additionally, this study highlights the need to carefully consider what comparison groups should be used to examine factors associated with CiST use.

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.

Abstract
BACKGROUND This study provides a comprehensive, population-based examination of tobacco use among both career and volunteer firefighters. METHODS Data are from a population-based cohort study of randomly selected career (N = 11) and volunteer (N = 13) departments comprised of 677 male firefighters. RESULTS Unadjusted rates of smoking were 13.6% and 17.4% for career and volunteer firefighters, respectively. Smoking rates were less than a comparable occupational group (military personnel) and adult males in the states represented. Smokers were more likely to have been diagnosed with an anxiety disorder (OR = 5.8; P = 0.010), have an elevated CAGE alcohol problem score (OR = 2.9; P = 0.040), and more likely to report driving after drinking too much (OR = 4.5; P = 0.020) compared to never-smokers. Large percentages of career (18.4%) and volunteer (16.8%) firefighters used smokeless tobacco. CONCLUSIONS Smoking among firefighters is associated with other significant health and safety risks. High rates of smokeless tobacco use suggest that the fire service is an important target for intervention. Thus, despite strong statements against smoking by the fire service, the need to maintain high levels of health and fitness and relatively low smoking rates, a significant proportion of firefighters continue to use tobacco products.

Abstract
INTRODUCTION Concomitant use of two forms of tobacco is an increasing public health concern, yet there is little consensus regarding a consistent definition of so-called "dual use." We defined dual use as cigarette and smokeless tobacco (ST) consumption with either product used daily or nondaily. METHODS We analyzed a cohort of 36,013 Air Force recruits. We categorized dual tobacco use across 2 dimensions, type of tobacco products (cigarettes, ST, or others), and the frequency of use (daily vs. nondaily). We determined how varying the definition impacted the prevalence estimates and evaluated the prevalence estimate based on our recommended definition of dual use. Multivariate logistic regression analysis was used to evaluate the risk profile of dual users of ST and cigarettes versus mono users of ST and mono users of cigarettes. RESULTS Varying definitions of dual use vary prevalence estimates 50-fold (0.5%-25.3%). Including only ST and cigarettes narrows the prevalence estimate to less than 4-fold (2.0%-9.7%). Dual users are more likely to be young Caucasian males, with lower education, and from families with relatively higher incomes. Compared with mono users, dual users of cigarettes and ST have a distinct pattern of risk profiles. CONCLUSIONS Depending on the definition of dual use, markedly different prevalence and risk profiles are observed. Dual users of ST and cigarettes are a unique group of tobacco users. We propose a common definition of dual use to advance our understanding of this unique group.

Abstract
This study examined the prevalence of tobacco use and factors associated with pre-military service cigarette and smokeless tobacco use. From January 2000 to December 2006, military students arriving for Advanced Individual Training at the U.S. Army Ordnance School completed a questionnaire that asked about their use of tobacco products. The prevalence of smokeless tobacco use from 2000 to 2006 for women generally decreased, as did the number of cigarettes smoked per day by men. For men and women, factors associated with cigarette use included younger age, Caucasian race, and use of smokeless tobacco. Factors associated with smokeless tobacco use among men included younger age, Caucasian race, and cigarette use. For women, cigarette use was the only factor associated with smokeless tobacco use. The identified factors in this study could be used to establish strategies in the future to reduce tobacco use in the military.

Differences between intermittent and light daily smokers in a population of U.S. military recruits. Nicotine Tob Res 2010; 12:465-73. [PMID: 20203108 PMCID: PMC2861885 DOI: 10.1093/ntr/ntq025] [Citation(s) in RCA: 32] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2009] [Accepted: 02/04/2010] [Indexed: 11/13/2022]
Abstract
INTRODUCTION Few studies have assessed differences between intermittent and light smokers, particularly among young adults. Exploring these differences promotes a systematic approach to research and treatment in low-level smokers. This study explored demographic, tobacco-related, and psychosocial predictors of intermittent nondaily smoking relative to light smoking among basic military training (BMT) recruits. The impact of smoking status on abstinence rates at follow-up was also assessed. METHODS Participants were 5,603 U.S. Air Force BMT intermittent nondaily (n = 3,134) or light daily (n = 2,469) smoking recruits participating in a population-based group randomized trial targeting tobacco use prevention and cessation (Klesges et al., 2006, Efficacy of a tailored tobacco control program on long-term use in a population of U.S. military troops. Journal of Consulting and Clinical Psychology, 74, 295-306.). Participants completed baseline measures assessing demographics; tobacco use and history; and common social, attitudinal, and behavioral risk factors for tobacco use. Flights of recruits were randomly assigned to a tobacco use intervention or health education control intervention. At the 1-year follow-up, participants reported 7-day point prevalence and continuous abstinence. RESULTS Intermittent nondaily smoking relative to light daily smoking was associated with lesser perceived addiction, intermittent and daily use of smokeless tobacco, nonsmoking male and female heads of household, lesser likelihood of smoking while stressed or while bored, and higher likelihood of intentions to quit smoking. Intermittent smokers were significantly more likely than light daily smokers to report abstinence at follow-up. DISCUSSION Intermittent and daily light smokers differ on several tobacco-related and psychosocial variables. Attending to these factors in prevention and cessation programs may enhance abstinence in both groups.

How are lifetime polytobacco users different than current cigarette-only users? Results from a Canadian young adult population. Addict Behav 2009; 34:1069-72. [PMID: 19646820 DOI: 10.1016/j.addbeh.2009.06.009] [Citation(s) in RCA: 40] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2009] [Revised: 05/29/2009] [Accepted: 06/29/2009] [Indexed: 11/17/2022]
Abstract
Current cigarette smoking combined with ever use of other tobacco products (lifetime polytobacco use) is important to examine as users may be at greater risk for illicit drug use, nicotine addiction, and adverse health outcomes. We determined estimates and patterns of lifetime polytobacco use and conducted multivariable analyses to determine demographic, family and friend, psychosocial, and lifestyle factors associated with use among a sample of Canadian young adults. Overall prevalence was 36.3% for current cigarette use; 10.1% for current cigarette use only and 26.2% for lifetime polytobacco use. Among polytobacco users, current cigarette use and ever cigar use was most frequent (67.2%). For males, the final model contained demographic, family and friends, and lifestyle factors. For females, the final model also included psychosocial factors. Illicit drug use was the strongest significant predictor for lifetime polytobacco use among males. We found gender specific differences when comparing lifetime polytobacco users to current cigarette-only users, in particular; male lifetime polytobacco users were more likely to use drugs and alcohol. Interventions focusing on individual substances should consider addressing combinations of use.

Demographic profiles of smokeless tobacco users in the U.S. Am J Prev Med 2009; 37:29-34. [PMID: 19524142 DOI: 10.1016/j.amepre.2009.03.010] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/29/2008] [Revised: 12/22/2008] [Accepted: 03/10/2009] [Indexed: 10/20/2022]
Abstract
BACKGROUND Users of smokeless tobacco (chew or snuff) in the U.S. are viewed demographically as being homogeneous. Prior studies have demonstrated such homogeneity in national survey data but have not utilized latent-variable methods. The objective of this study was to determine whether a single group or underlying subgroups best characterize users of smokeless tobacco. METHODS Men aged >17 years who had used smokeless tobacco in the past month (n=4583) were selected from the 2003, 2004, and 2005 National Surveys on Drug Use and Health. A latent-class analysis, conducted in 2008, was based on individual response patterns from six demographic variables and three items pertaining to the use of smokeless tobacco. RESULTS Four latent classes were identified: older chew users (17.2%); younger poly-tobacco users (28.7%); skilled laborers with a high school diploma (27.5%); and educated professionals (26.6%). External validation of these classes indicated that older chew users and younger poly-tobacco users were more likely than the educated professionals to be former and current smokers, respectively. CONCLUSIONS While users of smokeless tobacco in the U.S. are predominantly white men, they are more heterogeneous with respect to education, occupation, and residency than commonly is perceived.

Abstract
Although smoking shows a strong negative association with religiousness, no studies have appeared of use of smokeless tobacco (ST) and religiousness. To assess an association of use of ST and religiousness, data from 9,374 men aged 17 years and over with complete data on self-reported frequency of attendance at religious services and use of smokeless tobacco were analyzed. Among men aged 17–29 years, 4.9% of frequent attenders (>=24 times/y) and 9.4% of others (<24 times/y) were current users of ST (p=0.002). After adjusting for multiple confounders by logistic regression, infrequent attenders were twice as likely as frequent attenders to be ST users: odds ratio 2.09, 95% confidence limits 1.12–3.92, p=0.02. This negative association suggests a protective effect of early-life religiousness on ST use, which might be taken into account in planning ST prevention efforts.

Are smokers only using cigarettes? Exploring current polytobacco use among an adult population. Addict Behav 2007; 32:2411-9. [PMID: 17490825 DOI: 10.1016/j.addbeh.2007.04.001] [Citation(s) in RCA: 58] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/12/2006] [Revised: 02/08/2007] [Accepted: 04/02/2007] [Indexed: 11/27/2022]
Abstract
BACKGROUND The primary focus of tobacco prevention and cessation interventions has been on cigarette smoking. Polytobacco use (the concurrent use of cigarettes and one or more other tobacco product[s]), may present additional health risks and make cessation more difficult. METHODS We determined population estimates of tobacco product use and of polytobacco use for more than 50000 adults from 10 states. Logistic regression analyses were used to determine factors independently associated with polytobacco use among men only (due to low use among women). RESULTS The overall adult prevalence was 22.4% for cigarettes and 3.4% for polytobacco use. Polytobacco use was more common among men who smoked cigarettes, with 26.0% using at least one other product, compared to 4.4% of women cigarette smokers. Polytobacco use among men was significantly associated with younger age, all races/ethnicities except Hispanic, less educational attainment, less income, and more-than-moderate alcohol use. CONCLUSIONS Prevention and cessation efforts need to target use of other forms of tobacco besides cigarettes, especially among younger men and men who are more-than-moderate drinkers of alcohol.

Abstract
BACKGROUND As smoking prevalence declines in the United States, it is important to understand if smokeless tobacco (SLT) use is also changing and if so, among what groups. METHODS We examine the prevalence of SLT use and smoking, 1992-2002, using the Current Population Survey-Tobacco Use Supplements (CPS-TUS), which used US nationally representative samples based on stratified clusters of households. RESULTS Consistent with declines in smoking, the prevalence of current SLT use declined over the period 1992-2002 for males and females ages 18 and older. The overall separate declines in SLT use and in smoking are mirrored by a decline in concurrent use of SLT and cigarettes. SLT use is becoming more associated with white males, but use is declining faster among the youngest males. CONCLUSIONS The findings indicate that relative reductions in smoking prevalence are exceeded by relative reductions in SLT use, with sizeable reductions in concurrent use. These results suggest that the stricter cigarette policies of recent years may not only reduce cigarette use, but also the use of alternative tobacco products. In light of potential policy implications of SLT use as a potential reduced exposure product (PREP), current survey methods require more careful measurement of SLT use in terms of initiation, duration, quantity, and cessation.

Abstract
In the search for risk factors involved in the etiology of lymphoproliferative malignancies there is still inconsistent evidence regarding effects of smoking tobacco, and the role of smokeless tobacco is poorly investigated. New evidence indicates that excess body weight increases the risk of NHL and HD. To determine if tobacco use of various forms and high Body Mass Index (BMI) affect the occurrence of these neoplasms, we conducted a prospective cohort study on over 330,000 Swedish construction workers included in the Construction Industry Working Environment and Health program. Information on smoking, snuff dipping, height and weight was gathered by self administered questionnaires together with personal interviews. Cancer incidence was ascertained through the year 2000 by record linkage to the nationwide Swedish Cancer Registry, Migration Registry and Cause of Death Registry. At the end of follow up, 1,309 subjects had been diagnosed with NHL (including chronic lymphocytic leukemia) and 205 with HD respectively. Age adjusted incidence rate ratios were computed using Cox proportional Hazard regression modeling. Smoking cigarette, pipe or cigar was not associated with NHL or HD. There was no evidence indicating a relation between quantity and duration of smoking and NHL or HD risk. No link was found between NHL and usage of smokeless tobacco. Having a BMI of 30 or higher did not convey excess risk of developing NHL or HD compared to normal weight (BMI 18.6-24.9). We conclude that tobacco smoking and high BMI do not entail an increased risk of NHL and HD. Our findings of a relation between the duration of snuff dipping and HD need further investigation.

Abstract
Accelerating the decline in smoking prevalence requires an understanding of changes in the concurrent use of and the substitution between different tobacco products, such as smokeless tobacco (SLT) and cigarettes. SLT could play an important role in reducing the toll of smoking-related illness and premature mortality. Research examining the role of tobacco control policies in explaining concurrent use of SLT and cigarettes has been minimal. Using the Current Population Survey Tobacco Use Supplements (CPS-TUS), we examined tobacco control policies in relationship with adult males' SLT use concurrent with smoking over the period 1992-2002. Consistent with the decline in smokeless-only and cigarette-only rates, concurrent use of SLT and cigarettes declined during the period. SLT users, faced with home or workplace smoking bans, are less likely to report smoking. Smokers with a home ban appear more likely to use SLT, but in more recent years, smokers with a workplace ban are less likely to use SLT. Tobacco excise taxes do not signal substitution between cigarettes and SLT products. Understanding current use patterns of the range of tobacco products, including their interaction with available policy levers, is vital in assessing whether changes that might promote substitution of arguably less toxic SLT products for highly toxic cigarettes are likely to lead to net public health gains or losses. Findings of the present study, in concert with other research about transitional probabilities between behavioral states, will inform the design of an effective policy framework that supports the objective of reducing tobacco-related death and disease.

Abstract
OBJECTIVE Male fertility is affected by a variety of lifestyle habits that include tobacco use. A large population of Indian men is addicted to tobacco chewing. The objective of our study was to assess the relationship between tobacco chewing in these Indian men--who were part of an infertile couple--and their sperm characteristics. DESIGN Retrospective study. SETTING Private infertility clinic. PATIENT(S) Six hundred thirty-eight male patients undergoing infertility evaluations were grouped according to the frequency of their tobacco chewing habit: mild (< 3 times/day, n = 177), moderate (3-6 times/day, n = 264), and severe (> 6 times/day, n = 197). INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Sperm characteristics (concentration, motility, morphology, and viability). RESULT(S) Sperm concentration, percentage motility, morphology, and percentage viability were significantly higher in the mild group vs. the moderate group and in the moderate group vs. the severe group. The percentage of men with azoospermia rose with the level of addiction (1%, 3%, and 14%) as did the percentage of men with oligoasthenoteratozoospermia (2%, 8%, and 29%), although the differences were not statistically significant. CONCLUSION(S) In our study, use of chewing tobacco by a group of Indian men who were undergoing infertility evaluation was strongly associated with a decrease in sperm quality and to a lesser extent with oligoasthenozoospermia or azoospermia. Infertile men should be counseled about the adverse effects of tobacco chewing on sperm quality.

Abstract
Although considerable research has been conducted on smokeless tobacco (ST) use in males, much less is known about the characteristics of female ST users. The present study examined the prevalence and correlates of lifetime ST use among female Air Force recruits (N=9,087). Participants were surveyed during Basic Military Training regarding their history of tobacco use and other health risk behaviors. Although the prevalence of current ST use was low (<1%; n=34), 6.6% (n=599) had tried ST. Multivariate logistic regression analysis indicated that lifetime ST use was related to ethnicity, with Native Americans and Whites being most likely to have tried ST. Additional correlates of lifetime ST use included post-high-school education (OR=1.26, 95% CI=1.03-1.55); weekly acts of road rage (OR=1.48, 95% CI=1.06-2.06); frequent arguing (OR=1.71, 95% CI=1.18-2.48); daily or near-daily alcohol consumption (OR=1.71, 95% CI=1.03-2.82); current cigarette use (OR=3.80, 95% CI=2.42-5.94); and experimental use of cigars (OR=4.01, 95% CI=3.22-5.01), pipes (OR=2.23, 95% CI=1.64-3.03), and clove cigarettes (OR=1.23, 95% CI=1.01-1.49), all of which were associated with an increased likelihood of ST use. Results suggest that female recruits who have ever used ST engage in a variety of risk behaviors including use of other tobacco products and alcohol, as well as additional harmful behaviors.

Abstract
BACKGROUND Although tobacco use appears common among Native Americans, the study of dual use of cigarettes and smokeless tobacco has been neglected. The current study examines tobacco use among a sample of Native American adolescents. Also, it considers how the psychological factor of anger may relate to tobacco use. METHODS The participants were 513 Native American students from a national sample in grades 6, 8, and 10 in the United States. Cluster analysis was used to identify anger types, and these types were compared on their tobacco use. RESULTS Cluster analysis identified four anger types. One type was the Externalizing Type, characterized by the tendency to show externalizing behaviors such as fighting and yelling. This type had an elevated rate of tobacco use. In terms of an odds ratio, the Externalizing Type was about 10 times more likely to smoke, about 6 times more likely to use smokeless tobacco, and about 8 times more likely to show dual use. The majority of dual users were the Externalizing Type. CONCLUSIONS The results suggest that externalizing anger types are more likely to use tobacco, and that smoking cessation programs for teens could be more effective when they address anger issues.

Abstract
BACKGROUND This study examined the characteristics, tobacco use patterns over time, and predictors of tobacco cessation among concomitant users of cigarettes and smokeless tobacco. METHODS Participants were employed adults residing in the southeastern United States who participated in the Working Well cancer prevention trial. Participants were assessed at baseline and followed-up 4 years later. RESULTS AND CONCLUSIONS The study yielded several key findings: (a) the prevalence of concomitant smoking and smokeless tobacco use was high among males and nonexistent among females, (b) the characteristics of concomitant users were relatively distinct from those of both smokers and smokeless tobacco users, (c) concomitant users exhibited substantial variability in their tobacco use patterns and were less likely to stop using tobacco than were smokers or smokeless tobacco users, (d) indicators of nicotine dependence predicted tobacco cessation for both smokers and smokeless tobacco users, but were largely unrelated to tobacco cessation among concomitant users, and (e) demographics, environmental variables, and measures derived from the transtheoretical model were not consistent predictors of tobacco cessation after controlling for nicotine dependence.

Abstract
BACKGROUND This study was designed to test the hypothesis that smokeless tobacco (SLT) serves as a gateway drug for smoking among young adult males. Methods. A cohort (n = 7,865) of U.S. Air Force recruits who claimed to have never smoked cigarettes was followed prospectively for 1 year. The participants were male, 32.9% were ethnic minorities, and their average age was 19.84 years (SD = 2.29). Among recruits entering basic military training, 403 (5.1%) reported current SLT use and 198 (2.5%) reported a past history of SLT use. RESULTS At the 1-year follow-up current SLT users were 233% more likely to have initiated smoking than nonusers (odds ratio = 2.33, 95% CI = 1.84-2.94). Similarly, recruits who reported past SLT use were 227% more likely to begin smoking than participants who had never used SLT (odds ratio = 2.27, 95% CI = 1.64-3.15). SLT use remained a potent predictor of smoking initiation in a multivariate logistic model that included demographic factors and other risk factors for initiation. CONCLUSIONS SLT use appears to be an important predictor of smoking initiation among young adult males. This study suggests that smoking prevention and cessation programs should also include strategies related to SLT use.
