    Although sport participation among adolescents has been found to lower the risk of traditional cigarette smoking, no studies to date have assessed if this type of physical activity lowers the risk of e-cigarette use among adolescents. National data from the 2014 and 2015 Monitoring the Future study of 12th-grade students were used and analyses were conducted in 2016. Measures for past 30-day e-cigarette use and traditional cigarette smoking were used to assess differences between adolescents who participated in at least one competitive sport during the past year and adolescents who did not. Differences in e-cigarette use and traditional cigarette smoking were assessed between 13 different sports to determine which sports were associated with a greater or lower risk of these behaviors. Adolescents who participated in at least one competitive sport were less likely to engage in past 30-day traditional cigarette smoking (AOR=0.73, 95% CI=0.538, 0.973) and past 30-day dual use of traditional cigarettes and e-cigarettes (AOR=0.66, 95% CI=0.438, 0.982) when compared with their nonparticipating peers. Adolescents who participated in baseball/softball and wrestling were at greatest risk of e-cigarette use. Of the 13 assessed sports, none were found to lower the odds of e-cigarette use. No significant evidence was found that participation in a sport was a protective factor against e-cigarette use. Certain types of athletes are at an elevated risk of e-cigarette use, and prevention efforts targeted at these specific sports should be considered by school administrators.

    The purpose of the study was to explore the relationship between the exposure of adolescents in the seventh and eighth grades to cigarette advertising and their being smokers. A survey questionnaire given to 602 adolescents assessed their exposure to cigarette advertising and provided measures of their smoking behavior, demographic characteristics, and some psychosocial variables. The results indicated that exposure to cigarette advertising and having friends who smoked were predictive of current smoking status. Adolescents with high exposure to cigarette advertising were significantly more likely to be smokers, according to several measures of smoking behavior, than were those with low exposure to cigarette advertising. The findings extend previous research identifying factors that may play a role in the initiation and maintenance of smoking among adolescents. PMID:8464979

    During the past 30 years, tobacco use among adolescents has substantially increased, resulting in major health problems associated with tobacco consumption. The purpose of this study was to identify adolescent smoking behaviors and to determine the relationship among smoking, specific demographic variables, and health risk behaviors. The sample consisted of 93 self-selecting adolescents. An ex post facto design was used for this study and data were analyzed by using nonparametric statistics. Findings included a statistically significant relationship between lifetime cigarette use and ethnicity. Statistically significant relationships were also found among current cigarette use and ethnicity, alcohol use, marijuana use, suicidal thoughts, and age at first sexual intercourse. Nurses and other providers must recognize that cigarette smoking may indicate other risk behaviors common among adolescents. Copyright 2001 by W.B. Saunders Company

    China produces the majority of the world's electronic cigarettes (e-cigarettes) and e-cigarettes have become popular in the country, especially among young people. However, little is known about the characteristics of e-cigarette use in China and how it is associated with smoking cessation behavior. This study focuses on the adolescent group in China and examines their perception and use of e-cigarettes and the association with smoking abstinence. We use a mobile app-based survey on smoking behavior conducted in November 2015 in China, and focus on a sample of 2042 adolescents aged between 12 and 18. Awareness, perception, use of e-cigarettes are examined as well as the behaviors of promoting e-cigarettes and of smoking cessation. A logistic regression is performed to test the association between e-cigarette use and smoking abstinence behavior. In 2015, nearly 90% of the surveyed adolescents in China were aware of e-cigarettes, while over a quarter of the respondents were ever users. The odds ratio for ever users of e-cigarettes to have tried to quit smoking conventional cigarettes was 1.60 that of never users. For those who tried to quit smoking, 36.02% indicated that they used e-cigarettes to help quit. However, only 13.52% of those who had used e-cigarettes to help quit smoking were successful in quitting. This study is one of the first empirical research on e-cigarette use among Chinese adolescents. E-cigarettes are widely known and quite popular among Chinese adolescents. As the association between e-cigarette use and smoking cessation behavior is less than clear, more empirical research is called for to help form evidence-based regulatory policy on e-cigarettes in China.

    As part of efforts to develop a smoking control strategy for Japanese adolescents, the results of two nationwide surveys on adolescent smoking behaviour were compared. Descriptive study on smoking behaviour among high school students was conducted. Self-reporting anonymous questionnaires were administered to 115,814 students in 1996 and 106,297 in 2000 through randomly sampled junior and senior high schools throughout Japan. Smoking prevalence, proportion of smokers by usual sources of cigarettes, national estimated cigarettes consumed by minors, share of cigarette brands smoked by high school students. The experiment rate among junior high school boys decreased in 2000 compared with that in 1996, whereas current and daily smoking rates did not. Although prevalence among Japanese girls was much lower than that among boys, prevalence among girls increased in 2000. The main source of cigarettes among high school smokers was vending machines. The proportion of smokers who usually purchased cigarettes from vending machines increased in 2000, in spite of the 1998 introduction of restrictions on night-time operations. Japanese adolescents were more likely than adults to smoke American cigarette brands, and the adolescent market share of American brands has increased rapidly, especially for menthol brands. This survey revealed the seriousness of the problem of smoking behaviour among Japanese high school students, and suggested that this behaviour may be influenced by social environmental factors, including the marketing strategies of the tobacco industry. Action should be taken to reduce the prevalence and impact of pro-tobacco marketing messages and to abolish cigarette vending machines.

    The aim of this paper is to report the rate of current and ever cigarette smoking and explore correlates of current cigarette smoking among adolescents aged 13-15 in Viet Nam. This analysis was derived from GYTS survey, which comprised of 3,430 adolescents aged 13-15, conducted in 2014 in 13 cities and provinces of Viet Nam. We calculated the weighted rates of current and ever cigarette smoking and reported patterns of smoking behavior. We also performed logistic regression to explore correlates of current cigarette smoking behavior. The weighted rate of ever cigarette smoking was 9.5% (95% confidence interval (CI): 8.5 %-10.5%), in which the weighted rate among males (15.4%; 95% CI: 13.6%-17.0%) was higher than that among females (4.2%; 95% CI: 3.3%-5.1%). The weighted rate of current cigarette smoking was relatively low at 2.5% (95%CI: 2.0%- 3.0%) with higher weighted rate among males (4.9%; 95% CI: 3.8%-5.9%) compared to the corresponding figure among females (0.2%; 95% CI: 0.0 %-0.5%). Current cigarette smoking was significantly higher among males than females, in students aged 15 versus 13 years old, and in students who had several or all close friends smoking and students with daily observation of smoking at school. For greater smoking reduction outcomes, we recommend that tobacco interventions for adolescents should consider targeting more male students at older ages, establish stricter adherence to school-based banning of cigarette smoking, engage both smoking and nonsmoking adolescents and empower adolescents to resist peer smoking influence as well as changing their norms or beliefs towards smoking benefits.

    The purpose of this study was to examine the prevalence of cigarette smoking and to explore its relationship with individual, family, school, and psychological factors among Korean adolescents. As part of the Korean Institute for Health and Social Affairs' Adolescent Health Survey, 5,209 eighth graders and 4,677 eleventh graders from 70 junior and senior high schools completed a self-administered questionnaire during school hours in 1989. Current prevalence of cigarette smoking was 8.45% (15.43% of boys and 1.28% of girls). Smoking prevalence increased with age among boys. Based on logistic regression analyses, perceived peer use was most strongly associated with smoking status (OR = 9.97 for boys; and 68.27 for girls). Academic stress, grade, and type of school were also associated with smoking status for both boys and girls. In addition, mother's smoking, birth order, and urbanity were associated with smoking status for boys. Implications of the results for prevention efforts to inhibit the onset of cigarette smoking among Korean adolescents are discussed.

    Electronic cigarettes (e-cigarettes) may help smokers reduce the use of traditional combustible cigarettes. However, adolescents and young adults who have never smoked traditional cigarettes are now using e-cigarettes, and these individuals may be at risk for subsequent progression to traditional cigarette smoking. To determine whether baseline use of e-cigarettes among nonsmoking and nonsusceptible adolescents and young adults is associated with subsequent progression along an established trajectory to traditional cigarette smoking. In this longitudinal cohort study, a national US sample of 694 participants aged 16 to 26 years who were never cigarette smokers and were attitudinally nonsusceptible to smoking cigarettes completed baseline surveys from October 1, 2012, to May 1, 2014, regarding smoking in 2012-2013. They were reassessed 1 year later. Analysis was conducted from July 1, 2014, to March 1, 2015. Multinomial logistic regression was used to assess the independent association between baseline e-cigarette use and cigarette smoking, controlling for sex, age, race/ethnicity, maternal educational level, sensation-seeking tendency, parental cigarette smoking, and cigarette smoking among friends. Sensitivity analyses were performed, with varying approaches to missing data and recanting. Use of e-cigarettes at baseline. Progression to cigarette smoking, defined using 3 specific states along a trajectory: nonsusceptible nonsmokers, susceptible nonsmokers, and smokers. Individuals who could not rule out smoking in the future were defined as susceptible. Among the 694 respondents, 374 (53.9%) were female and 531 (76.5%) were non-Hispanic white. At baseline, 16 participants (2.3%) used e-cigarettes. Over the 1-year follow-up, 11 of 16 e-cigarette users and 128 of 678 of those who had not used e-cigarettes (18.9%) progressed toward cigarette smoking. In the primary fully adjusted models, baseline e-cigarette use was independently associated with progression to smoking

    Although most agree that the association between tobacco marketing and youth smoking is causal, few studies have assessed the specificity of this association. This study aims to examine the specificity of the association between cigarette advertising and teen smoking. A cross-sectional survey of 3415 German schoolchildren aged 10-17 years was conducted using masked images of six cigarette brands and eight other commercial products in 2008. The exposure variable was a combination of contact frequency (recognition) and brand names (cued recall). Sample quartile (Q) exposure to advertisement exposure was calculated in 2009. Outcome variables were ever tried and current (monthly) smoking, and susceptibility to smoking among never smokers. The prevalence of ever smoking was 31.1% and that of current smoking was 7.4%, and 35.3% of never smokers were susceptible to smoking. Ad recognition rates ranged from 15% for a regionally advertised cigarette brand to 99% for a sweet. Lucky Strike and Marlboro were the most highly recognized cigarette brands (with ad recognition rates of 55% and 34%, respectively). After controlling for a range of established influences on smoking behaviors, the adjusted ORs for having tried smoking were 1.97 (95% CI=1.40, 2.77) for Q4 exposure to cigarette ads compared with adolescents in Q1, 2.90 (95% CI=1.48, 5.66) for current smoking, and 1.79 (95% CI=1.32, 2.43) for susceptibility to smoking among never smokers. Exposure to ads for commercial products other than cigarettes was significantly associated with smoking in crude but not multivariate models. This study underlines the specificity of the relationship between tobacco marketing and youth smoking, with exposure to cigarette ads, but not other ads, being associated with smoking behavior and intentions to smoke. This finding suggests a content-related effect of tobacco advertisements. 2010 American Journal of Preventive Medicine. Published by Elsevier Inc. All rights reserved.

    Although existing evidence indicates that e-cigarette use is a risk factor for cigarette smoking initiation, mechanisms of this association are not yet known. E-cigarette users perceive e-cigarette use to be less harmful relative to conventional cigarettes, but their absolute perceptions of addictiveness of conventional cigarette smoking are unknown. This study examines how e-cigarette users compare with nonusers (non-e-cigarette users/nonconventional cigarette smokers), conventional cigarette smokers, and dual users on perceptions of harm and the addictiveness of conventional cigarette smoking and on other known predictors of cigarette smoking such as peer smoking, influence of antismoking ads, and risk-taking propensity. National samples of 8th- and 10th-grade students from 2014 and 2015 (N = 14,151) were obtained from the Monitoring the Future Study. Multivariate logistic regression models were used to examine relationships between adolescent smoking status and perceptions of harm and the addictiveness of conventional cigarette smoking while controlling for potential confounders. E-cigarette users had lower perceptions of the addictiveness of conventional cigarette smoking compared with nonusers but higher than cigarette smokers and dual users. E-cigarette users reported lower influence by antismoking ads, more conventional cigarette-smoking peers, and greater risk-taking propensity than nonusers. E-cigarette users and cigarette smokers did not differ in their perceived harm of conventional cigarette smoking or in their risk-taking propensity. E-cigarette users' attitudes and perceptions regarding conventional cigarette smoking may leave them vulnerable to becoming conventional cigarette smokers. Future studies should explore the prospective relationship between smoking-related perceptions of conventional cigarette smoking among e-cigarette users and the onset of cigarette smoking.

    Objective There is little evidence on the consequences of electronic cigarette (e-cigarette) use in adolescence. With a multiethnic sample of nonsmokers, we assessed the relation between e-cigarette use and social-cognitive factors that predict smoking combustible cigarettes (cigarettes). Methods School-based cross-sectional survey of 2,309 high school students (M age 14.7 years). Participants reported on e-cigarette use and cigarette use; on smoking-related cognitions (smoking expectancies, prototypes of smokers) and peer smoker affiliations; and on willingness to smoke cigarettes. Regression analyses conducted for non-cigarette smokers tested the association between e-cigarette use and willingness to smoke cigarettes, controlling for demographics, parenting, academic and social competence, and personality variables. Structural equation modeling (SEM) analyses tested whether the relation between e-cigarette use and willingness was mediated through any of the three smoking-related variables. Results Nonsmokers who had used e-cigarettes (18% of the total sample) showed more willingness to smoke cigarettes compared to those who had never used any tobacco product; the adjusted odds ratio was 2.35 (95% confidence interval 1.73 – 3.19). Additionally, willingness prospectively predicted smoking onset. SEM showed that the relation between e-cigarette use and willingness to smoke was partly mediated through more positive expectancies about smoking but there was also a direct path from e-cigarette use to willingness. Conclusions Among adolescent nonsmokers, e-cigarette use is associated with willingness to smoke, a predictor of future cigarette smoking. The results suggest that use of e-cigarettes by adolescents is not without attitudinal risk for cigarette smoking. These findings have implications for formulation of policy about access to e-cigarettes by adolescents. PMID:26261237

  12. How does electronic cigarette access affect adolescent smoking?

    Understanding electronic cigarettes' effect on tobacco smoking is a central economic and policy issue. This paper examines the causal impact of e-cigarette access on conventional cigarette use by adolescents. Regression analyses consider how state bans on e-cigarette sales to minors influence smoking rates among 12 to 17 year olds. Such bans yield a statistically significant 0.9 percentage point increase in recent smoking in this age group, relative to states without such bans. Results are robust to multiple specifications as well as several falsification and placebo checks. This effect is both consistent with e-cigarette access reducing smoking among minors, and large: banning electronic cigarette sales to minors counteracts 70 percent of the downward pre-trend in teen cigarette smoking for a given two-year period.

    The purpose of the present study is to examine the relation between magazine advertising for cigarettes and adolescent cigarette smoking. Participants (242 adolescents) reported their frequency of reading 46 magazines and their attention to cigarette ads. Recognition of cigarette ads, passive peer pressure (i.e., normative beliefs), and the smoker image also were assessed. Results indicate that exposure to cigarette advertising and recognition of ads augment the effect of passive peer pressure on smoking. In addition, a positive smoker image was associated with attention to advertising and mediated the relation between attention and smoking. It is suggested that the effect of magazine ads on adolescents should be considered in policymaking on cigarette advertising.

    To examine the association of family smoking status and exposure to secondhand smoke (SHS) at home with the use of electronic cigarettes among US adolescents, in particular the medication effect of SHS on the association between family smoking status and electronic cigarette use. Data from the 2013 National Youth Tobacco Survey were used and logistic regressions were conducted to model electronic cigarettes use. The mediation effect of SHS was tested using the Sobel-Goodman mediation test. Overall, 8.1 % of the US adolescents reported ever use of e-cigarettes. Among both the overall population and never-cigarette smokers, adolescents living in smoker households were significantly more likely to report ever use of e-cigarettes (p < 0.05). However, the associations were attenuated after including SHS exposure at home during the past 7 days. SHS exposure at home was positively associated with ever use of e-cigarettes, adjusting for family smoking status (p < 0.05). The association between smoking habits of the family and e-cigarette use was mediated through SHS exposure. The promotion of smoke-free home rules may help prevent the uptake of e-cigarettes among teenagers.

    2013-10-01

    Analyses used data from an extended longitudinal study to examine the relationship between childhood physical and sexual abuse (CPA and CSA, respectively) and adolescent and adult smoking behavior. Two questions guided the study: (1) Is there an association between childhood abuse and adolescent and adult smoking behavior? (2) Does the relationship between childhood abuse and later cigarette smoking differ for males and females? A censored-inflated path model was used to assess the impact of child abuse on adolescent and adult lifetime smoking prevalence and smoking frequency. Gender differences in significant model paths were assessed using a multiple-group approach. Results show no significant relation between CPA or CSA and risk of having ever smoked cigarettes in adolescence or adulthood. However, for males, both CPA and CSA had direct effects on adolescent smoking frequency. For females, only CSA predicted increased smoking frequency in adolescence. Adolescent smoking frequency predicted adult smoking frequency more strongly for females compared with males. CPA and CSA are risk factors for higher frequency of smoking in adolescence. Higher frequency of cigarette smoking in adolescence increases the risk of higher smoking frequency in adulthood. Results underscore the need for both primary and secondary prevention and intervention efforts to reduce the likelihood of childhood abuse and to lessen risk for cigarette smoking among those who have been abused.

    Despite the growing body of research in adolescent cigarette smoking, there is a lack of research on Asian American and Pacific Islander (AAPI) adolescents. This study examined the prevalence and psychosocial correlates of the past 30-day cigarette smoking in Asian American (AA) and Pacific Islander (PI) adolescents by utilizing a multi-systemic theory-the problem behavior theory. Using the 2006-07 High School Questionnaire of California Healthy Kids Survey, variables such as cigarette smoking, individual characteristics and external influences were assessed. Chi-square tests and generalized estimating equations were used in the analyses. PIs had higher past 30-day cigarette smoking rates than AAs. In the whole AAPI population, significant correlates of cigarette smoking included: positive and negative attitudes toward cigarettes, perceived harm of cigarettes, perceived prevalence of peer cigarette smoking, friend disapproval of cigarette use, previous drug use, truancy, and academic performance. Interaction results showed that truancy increased the odds of cigarette use for AAs only. The study found differential prevalence and correlate of cigarette smoking in addition to common psychosocial correlates in AAs and PIs. It sheds light on the importance of studying AAs and PIs separately and further exploring other potential variables that contribute to the prevalence discrepancy. Copyright © 2012 Elsevier Ltd.

    The U.S. Food and Drug Administration (FDA) is working to introduce new graphic warning labels for cigarette packages, the first change in cigarette warnings in more than 25 years. We sought to examine whether warnings discouraged participants from wanting to smoke and altered perceived likelihood of harms among adolescent males and whether these warning effects varied by age. A national sample of 386 non-smoking American males ages 11-17 participated in an online experiment during fall 2010. We randomly assigned participants to view warnings using a 2 × 2 between-subjects design. The warnings described a harm of smoking (addiction or lung cancer) using text only or text plus an image used on European cigarette package warnings. Analyses tested whether age moderated the warnings' impact on risk perceptions and smoking motivations. The warnings discouraged most adolescents from wanting to smoke, but lung cancer warnings discouraged them more than addiction warnings did (60% vs. 34% were "very much" discouraged, p<.001). Including an image had no effect on discouragement. The warnings affected several beliefs about the harms from smoking, and age moderated these effects. Adolescents said addiction was easier to imagine and more likely to happen to them than lung cancer. They also believed that their true likelihood of experiencing any harm was lower than what an expert would say. Our findings suggest that warnings focusing on lung cancer, rather than addiction, are more likely to discourage wanting to smoke among adolescent males and enhance their ability to imagine the harmful consequences of smoking. Including images on warnings had little effect on non-smoking male adolescents' discouragement or beliefs, though additional research on the effects of pictorial warnings for this at-risk population is needed as the FDA moves forward with developing new graphic labels.

    Background Tobacco industry cigarette advertising is associated with increased adolescent smoking, while counter tobacco advertising is associated with reduced smoking. As these campaigns compete for influence, there is a need to understand their inter-relationship on youth smoking. Methods This study reports data from a national population of families (n=1036) with an oldest child aged 10–13 years, identified by random digit dialling. Parent and child dyads completed baseline questionnaires in 2003. Adolescents were resurveyed in 2007–2008 (response rate 74%). Adjusted logistic regression explores associations between receptivity to cigarette and tobacco control advertising and adolescent smoking initiation. Results In 2007–2008, 57.9% of adolescents reported a favourite tobacco control advertisement and 43.3% reported being receptive to cigarette advertisements. Thirty per cent reported receptivity to cigarette and tobacco control advertisements. Among those receptive to cigarette advertising, having a favourite anti-smoking advertisement had a borderline significant association with a 30% lower smoking rate. Anti-industry tobacco control messages were three times more likely to be favourites of those who were receptive to cigarette advertising than other tobacco control advertising. Conclusions Receptivity to tobacco control advertising appeared to ameliorate the promotion of initiation from cigarette advertising. Anti-industry advertising appears to be the most effective counter for tobacco control and should be considered for wider use. A larger longitudinal study is needed to confirm these findings.

    The prevalence of adolescent electronic cigarette (e-cigarette) use has increased in most countries. This study aims to determine the relation between the frequency of e-cigarette use and the frequency and intensity of cigarette smoking. Additionally, the study evaluates the association between the reasons for e-cigarette use and the frequency of its use. Using the 2015 Korean Youth Risk Behavior Web-Based Survey, we included 6655 adolescents with an experience of e-cigarette use who were middle and high school students aged 13-18 years. We compared smoking experience, the frequency and intensity of cigarette smoking, and the relation between the reasons for e-cigarette uses and the frequency of e-cigarette use. The prevalence of e-cigarette ever and current (past 30 days) users were 10.1% and 3.9%, respectively. Of the ever users, approximately 60% used e-cigarettes not within 1 month. On the other hand, 8.1% used e-cigarettes daily. The frequent and intensive cigarette smoking was associated with frequent e-cigarette uses. The percentage of frequent e-cigarette users (≥10 days/month) was 3.5% in adolescents who did not smoke within a month, but 28.7% among daily smokers. Additionally, it was 9.1% in smokers who smoked less than 1 cigarette/month, but 55.1% in smokers who smoked ≥20 cigarettes/day. The most common reason for e-cigarette use was curiosity (22.9%), followed by the belief that they are less harmful than conventional cigarettes (18.9%), the desire to quit smoking (13.1%), and the capacity for indoor use (10.7%). Curiosity was the most common reason among less frequent e-cigarette users; however, the desire to quit smoking and the capacity for indoor use were the most common reasons among more frequent users. Results showed a positive relation between frequency or intensity of conventional cigarette smoking and the frequency of e-cigarette use among Korean adolescents, and frequency of e-cigarette use differed according to the reason for the use of

    Relations among measures of adolescent behavior were examined to determine whether cigarette smoking fits into a structure of problem behaviors-behaviors that involve normative transgression-or a structure of health-related behaviors, or both. In an ethnically and socioeconomically diverse sample of 1782 male and female high school adolescents, four first-order problem behavior latent variables-sexual intercourse experience, alcohol abuse, illicit drug use, and delinquency-were established and together were shown to reflect a second-order latent variable of problem behavior. Four first-order latent variables of health-related behaviors-unhealthy dietary habits, sedentary behavior, unsafe behavior, and poor dental hygiene-were also established and together were shown to reflect a second-order latent variable of health-compromising behavior. The structure of relations among those latent variables was modeled. Cigarette smoking had a significant and substantial loading only on the problem-behavior latent variable; its loading on the health-compromising behavior latent variable was essentially zero. Adolescent cigarette smoking relates strongly and directly to problem behaviors and only indirectly, if at all, to health-compromising behaviors. Interventions to prevent or reduce adolescent smoking should attend more to factors that influence problem behaviors.

    Tobacco industry cigarette advertising is associated with increased adolescent smoking, while counter tobacco advertising is associated with reduced smoking. As these campaigns compete for influence, there is a need to understand their inter-relationship on youth smoking. This study reports data from a national population of families (n=1036) with an oldest child aged 10-13 years, identified by random digit dialling. Parent and child dyads completed baseline questionnaires in 2003. Adolescents were resurveyed in 2007-2008 (response rate 74%). Adjusted logistic regression explores associations between receptivity to cigarette and tobacco control advertising and adolescent smoking initiation. In 2007-2008, 57.9% of adolescents reported a favourite tobacco control advertisement and 43.3% reported being receptive to cigarette advertisements. Thirty per cent reported receptivity to cigarette and tobacco control advertisements. Among those receptive to cigarette advertising, having a favourite anti-smoking advertisement had a borderline significant association with a 30% lower smoking rate. Anti-industry tobacco control messages were three times more likely to be favourites of those who were receptive to cigarette advertising than other tobacco control advertising. Receptivity to tobacco control advertising appeared to ameliorate the promotion of initiation from cigarette advertising. Anti-industry advertising appears to be the most effective counter for tobacco control and should be considered for wider use. A larger longitudinal study is needed to confirm these findings.

    In this analysis we examine the relationship between nonresidential father involvement with their children and adolescent smoking behavior using a nationally representative longitudinal dataset. We attempt to determine what influence, if any, nonresident fathers have in the development of this health risk behavior in their adolescent children while accounting for aspects of parenting and family life that have been hypothesized to also influence adolescent cigarette smoking. Data for this analysis come from the first 3 waves of the Longitudinal Study of Adolescent to Adult Health. Given the longitudinal nature of the data, we are able to ascertain whether nonresident father involvement affects adolescent cigarette smoking, an important advance in our understanding of the influence of fathers. We found that greater levels of nonresidential father involvement significantly decrease both the odds of participation in and the intensity of cigarette smoking, especially among girls. This influence is demonstrated not only in adolescence but persists into young adulthood. Our findings underscore the importance of adolescents' living arrangements and the role that nonresident fathers might play in influencing adolescent cigarette smoking, a health risk behavior of strong public health significance. Fathers make important contributions to the health and wellbeing of their children, and interventions focused on nonresident fathers in particular would likely be of significant help to the substance abuse prevention field. Interventions to support father involvement, particularly of nonresident fathers, with their children should be implemented as a preventive strategy to reduce the likelihood of adolescent cigarette smoking.

    The emerging trends and rapid growth of electronic cigarettes (e-cigarettes) among adolescents are being monitored closely. The trends are critical as policy to prevent uptake among adolescents is considered. The purpose of this study is to describe the prevalence of e-cigarette use and potential correlates for use. Associations between e-cigarettes, cigarettes, and hookah are assessed. This study used data from the 2013 Florida Youth Tobacco Survey. Prevalence estimates were calculated in 2014 and differences were determined based on CIs. Adjusted logistic regression models were used to identify correlates of e-cigarette use among participants based on demographic and other tobacco products used. There were no sex differences in middle school, whereas male high school students reported higher use than their female counterparts. Cigarette smoking and hookah use were significantly associated with ever and current e-cigarette use among both middle and high school students. Although e-cigarettes are being assessed as a potential replacement product for traditional tobacco, evidence from this study indicates the possibility of multiple product use among adolescents. E-cigarettes are not only associated with traditional cigarettes, but also with hookahs, a similar emerging product that offer tobacco flavors that may appeal to adolescents. Notably, many e-cigarette users also reported no cigarette or hookah use. Copyright © 2015 American Journal of Preventive Medicine. Published by Elsevier Inc. All rights reserved.

    E-cigarette use has been linked to onset of cigarette smoking among adolescents, but some commentators have suggested that this simply reflects high-risk adolescents being more likely to use e-cigarettes and to smoke. We tested whether the effect of e-cigarette use for smoking onset differs for youth who are lower versus higher on propensity to smoke. School-based survey with a longitudinal sample of 1136 students (9th-11th graders, mean age 14.7 years) in Hawaii, initially surveyed in 2013 (T1) and followed up 1 year later (T2). We assessed e-cigarette use, propensity to smoke based on 3 psychosocial factors known to predict smoking (rebelliousness, parental support and willingness to smoke), and cigarette smoking status. Analyses based on T1 never-smokers tested the relation of T1 e-cigarette use to T2 smoking status for participants lower versus higher on T1 propensity to smoke. The relation between T1 e-cigarette use and T2 smoking onset was stronger among participants with lower levels of rebelliousness and willingness and higher levels of parental support. A multiple logistic regression analysis with T2 smoking as the criterion tested the cross-product of T1 e-cigarette use and T1 smoking propensity score; the interaction (OR=0.88, p=0.01) indicated a significantly larger effect for smoking onset among lower risk youth. The results indicate e-cigarette use is a risk factor for smoking onset, not just a marker of high risk for smoking. This study provides evidence that e-cigarettes are recruiting lower risk adolescents to smoking, which has public health implications. Published by the BMJ Publishing Group Limited.

    Introduction: The prevalence of adolescent electronic cigarette (e-cigarette) use has increased in most countries. This study aims to determine the relation between the frequency of e-cigarette use and the frequency and intensity of cigarette smoking. Additionally, the study evaluates the association between the reasons for e-cigarette use and the frequency of its use. Materials and Methods: Using the 2015 Korean Youth Risk Behavior Web-Based Survey, we included 6655 adolescents with an experience of e-cigarette use who were middle and high school students aged 13–18 years. We compared smoking experience, the frequency and intensity of cigarette smoking, and the relation between the reasons for e-cigarette uses and the frequency of e-cigarette use. Results: The prevalence of e-cigarette ever and current (past 30 days) users were 10.1% and 3.9%, respectively. Of the ever users, approximately 60% used e-cigarettes not within 1 month. On the other hand, 8.1% used e-cigarettes daily. The frequent and intensive cigarette smoking was associated with frequent e-cigarette uses. The percentage of frequent e-cigarette users (≥10 days/month) was 3.5% in adolescents who did not smoke within a month, but 28.7% among daily smokers. Additionally, it was 9.1% in smokers who smoked less than 1 cigarette/month, but 55.1% in smokers who smoked ≥20 cigarettes/day. The most common reason for e-cigarette use was curiosity (22.9%), followed by the belief that they are less harmful than conventional cigarettes (18.9%), the desire to quit smoking (13.1%), and the capacity for indoor use (10.7%). Curiosity was the most common reason among less frequent e-cigarette users; however, the desire to quit smoking and the capacity for indoor use were the most common reasons among more frequent users. Conclusions: Results showed a positive relation between frequency or intensity of conventional cigarette smoking and the frequency of e-cigarette use among Korean adolescents, and frequency of e-cigarette

  7. Systematic review of social network analysis in adolescent cigarette smoking behavior.

    Social networks are important in adolescent smoking behavior. Previous research indicates that peer context is a major causal factor of adolescent smoking behavior. To date, however, little is known about the influence of peer group structure on adolescent smoking behavior. Studies that examined adolescent social networks with regard to their cigarette smoking behavior were identified through online and manual literature searches. Ten social network analysis studies involving a total of 28,263 adolescents were included in the final review. Of the 10 reviewed studies, 6 identify clique members, liaisons, and isolates as contributing factors to adolescent cigarette smoking. Significantly higher rates of smoking are noted among isolates than clique members or liaisons in terms of peer network structure. Eight of the reviewed studies indicate that peer selection or influence precedes adolescents' smoking behavior and intent to smoke. Such peer selection or influence accounts for a large portion of similarities among smoking adolescents. Adolescents who are identified as isolates are more likely to smoke and engage in risk-taking behaviors than others in the peer network structure. Given that the vast majority of current adult smokers started their smoking habits during adolescence, adolescent smoking prevention efforts will likely benefit from incorporating social network analytic approaches and focusing the efforts on isolates and other vulnerable adolescents from a peer selection and influence perspective. © 2011, American School Health Association.

    An analysis of the Global Youth Tobacco Survey for Kilimanjaro, Tanzania was carried out to assess sex differences in the prevalence rates and predictors of current cigarette smoking among in-school adolescents. A total of 2323 adolescents participated in the study of whom 53% were females and 47% males. The prevalence of current cigarette smoking was 3.0% and 1.4% among males and females, respectively. The common factors that were significantly positively associated with cigarette smoking between sexes were: having more pocket money, closest friend smoked cigarettes, seeing actors smoke on TV, videos or movies, and seeing advertisements for cigarettes at social gatherings. Seeing anti-smoking messages at social gatherings were negatively associated with smoking among both sexes. While having had something such as a t-shirt or pen with a cigarette brand logo on it was positively associated with cigarette smoking among males, it was negatively associated with cigarette smoking among females. Male adolescents older than 15 years, those in their 9th year of schooling, and those who had seen cigarette brand names on TV were more likely to smoke. Meanwhile, male respondents who were in their 8th year of schooling, had seen anti-smoking media messages, and advertisements for cigarettes in newspapers or magazines were less likely to smoke. Among female adolescents, those who had parents who smoked, and surprisingly those who perceived that cigarette smoking as harmful were more likely to smoke. Interestingly, seeing advertisement for cigarettes on billboards was negatively associated with smoking among female adolescents. Interventions aimed to reduce adolescent smoking need to be designed and implemented with due consideration of sex differences in these associated factors.

    Electronic cigarettes (e-cigarettes) are increasingly used in adolescents with unknown impacts on conventional cigarette smoking. We examined the associations of e-cigarette use with smoking intention, nicotine addiction and smoking cessation in Chinese adolescents. A total of 45,128 students (age 14.6 ± 1.9; boys 51.4%) from 75 randomly selected schools in Hong Kong reported e-cigarette use (in the past 30 days), conventional cigarette use and socio-demographic characteristics in an anonymous questionnaire survey. Adjusted odds ratios (AORs) of intention to smoke, morning smoking urge, intention to quit and quit attempts; and beta-coefficient (β) of cigarette consumption per day were calculated in relation to e-cigarette use. E-cigarette use was associated with intention to smoke with an AOR (95% CI) of 1.74 (1.30-2.31) in all students, 2.18 (1.12-4.23) in never and 2.79 (2.05-3.79) in ever smokers (non-significant interaction by smoking status). The associations were also significant in experimental and former smokers but not in current smokers. In current smokers, e-cigarette use was significantly associated with heavier smoking (β 2.54, 95% CI 1.28-3.81) and morning smoking urge (AOR 2.54, 95% CI 1.50-3.11), and non-significantly associated with lower quit intention (0.76, 0.52-1.09) and attempts (0.80, 0.56-1.23). E-cigarette use was associated with smoking intention in never, experimental and former smokers in Hong Kong Chinese adolescents. In current smokers, e-cigarette use was associated with nicotine addiction but not quit intention and attempts. Prospective studies with detailed measurements on e-cigarette use are warranted for further studies. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Youths with a minority sexual orientation (i.e., gay, lesbian, bisexual, and mostly heterosexual) are at high risk for cigarette smoking. We examined sexual-orientation disparities in smoking during adolescence and emerging adulthood and investigated the role of age at first smoking in contributing to smoking disparities. We used data from the Growing Up Today Study, a large longitudinal cohort of adolescents followed from ages 12 to 24 years (N = 13,913). Self-administered questionnaires filled out annually or biennially assessed age at first smoking, current smoking, frequency of smoking, number of cigarettes smoked daily, and nicotine dependence. Proportional hazards survival analysis and repeated measures regression estimated sexual-orientation differences in smoking. Compared with completely heterosexuals, lesbian/gay, bisexual, and mostly heterosexual youths smoked their first cigarette at younger ages, were more likely to be current smokers, and had higher frequency of smoking. Among past-year smokers, sexual-minority females smoked more cigarettes daily and scored higher on nicotine dependence than completely heterosexual females. In some instances, gender and age modified relationships between sexual orientation and smoking, with relative risk accentuated in female sexual minorities and in sexual minorities during younger ages. Younger age of smoking onset contributed to elevated smoking in mostly heterosexuals and bisexuals, and to a lesser extent in lesbians, but not in gay males. Sexual-orientation minorities are at greater risk for smoking during adolescence and emerging adulthood than heterosexuals. Disparities are larger in females and evident in early adolescence. Prevention and cessation efforts should target this population, preferably beginning in early adolescence.

    Smoking is harmful to the health of adolescents because their bodies are still growing. The aim of this study was to analyze the association between the smoking status of Korean adolescents' parents and friends and their own smoking behavior. The study assessed a nationwide sample of 72,060 middle and high students from the 10th Korea Youth Risk Behavior Web-based Survey (2014). Descriptive analysis, chi-square tests, and multiple logistic regression analysis were used to probe the association between family and friend smoking status and adolescent smoking behavior. The current cigarette smoking rates were 13.3% of boys and 4.1% of girls. The corresponding rates for electronic cigarette smoking were 4.1% and 1.5%, respectively. Higher exposure to secondhand smoke, smoking by any family member, more friends smoking, and witnessed smoking at school were associated with current smoking and electronic smoking. The smoking status of family and friends was significantly related to adolescent smoking behavior. These results should be considered in designing programs to control adolescent smoking.

    Increased exposure to cigarette advertisements is associated with increases in adolescent smoking but the reasons for this association are not known. This study evaluated whether the developmental maturity of the self-concept, operationalized as self-conflict, moderated smoking intentions following exposure to cigarette advertisements among adolescents who have never smoked. Eighty-seven adolescents (ages 11-17): (a) completed measures of self-conflict; (b) were exposed to 30 contemporary cigarette advertisements; and (c) rated their intentions to smoke following exposure to each ad. Younger adolescents with higher numbers of self-conflicts who also said that cigarette advertising was relevant to them had stronger smoking intentions compared to younger adolescents with lower numbers of self-conflicts after exposure to cigarette advertising. Self-conflict did not play as strong a role with older adolescents. Younger adolescents (i.e., middle school aged) who are having the most difficulty figuring out "who they are" are most susceptible to the effects of cigarette advertising.

    Objective Estimating the prevalence of cigarette smoking and its association with sociodemographic variables, sexual initiation and experience with domestic violence among adolescents from public schools in Guanambi, Bahia, Brazil. Method A crosssectional study carried out with adolescents. Data were collected through interviews guided by a structured instrument, and analyzed according to descriptive and inferential statistics with multiple logistic regression. Results A total of 370 adolescents participated in the study. The prevalence of cigarette smoking was 17.6% and a statistically significant association was observed between the variables: age over 15 years (PR = 5.63 and 95% CI: 1.33 - 23.85), males (PR = 2.53 and 95% CI: 1.47 - 4.37), no reported religion (PR = 1.93 and 95% CI: 0.99 - 3.75), working (PR = 2.17 and 95% CI: 1.25 - 3.74), onset of sexual activity (PR = 10.64 and CI= 95%: 5.31 - 21.33) and experience of domestic violence (PR = 3.61 and 95% CI: 2.07 - 3.28). Conclusion The prevalence of cigarette smoking and the associated variables point to the need for intervention strategies among more vulnerable groups of adolescents, encompassing family involvement and assistance from teachers and health professionals, in particular nurses working in Primary Care.

    Studies have shown that increased exposure to cigarette advertising increases adolescents' risk of smoking and moreover, that gender may play an important role in moderating how cigarette advertisements are viewed and processed. However, information about the particular features of cigarette advertising that interact with gender to promote smoking among adolescents is scarce. The purpose of this study was to examine if gender moderates the degree to which the relaxation valence (i.e., degree to which relaxing themes are emphasized) of cigarette advertisements is related to smoking intentions in a sample of never smoking adolescents. Regardless of brand type (of the seven brands studied), cigarette advertisements that displayed highly relaxing images were associated with increased intentions to smoke among female adolescents only. These results have implications for understanding what features of cigarette advertisements have the most influence among different groups of adolescents.

    To examine the main and interactive effects of parental history of regular cigarette smoking and parenting style on adolescent self-reported cigarette use. Predictors of adolescent self-reported cigarette use, including parents' history of regular cigarette smoking and two dimensions of parenting behavior, were analyzed in a sample of 934 predominately Caucasian (96.3%) parent-adolescent dyads. Families were drawn from the control group of a randomized control trial aimed at preventing adolescent substance use. In addition to the main effects of parents' history of regular smoking and parental warmth, logistic regression analysis revealed that the interaction of these two variables was associated with adolescent self-reported cigarette use. Parental warmth was associated with a decreased likelihood of the adolescent ever having smoked a cigarette; however, this was true only if neither parent had a history of regular cigarette smoking. Findings suggest that adolescent smoking prevention programs may be more efficacious if they address both parental history of regular smoking and parenting behavior.

    Background and Objectives Tobacco and cannabis use are both highly prevalent worldwide. Their co-use is also common in adults and adolescents. Despite this frequent co-occurrence, cessation from both substances is rarely addressed in randomized clinical trials. Given evidence that tobacco use may increase during cannabis cessation attempts, and additionally that tobacco users have poorer cannabis cessation outcomes, we explored tobacco outcomes, specifically cigarette smoking, from an adolescent cannabis cessation trial that tested the efficacy of N-acetylesteine (NAC). Methods Cannabis-dependent adolescents (ages 15–21; n=116) interested in cannabis treatment were randomized to NAC (1200 mg bid) or matched placebo for 8 weeks. Participants did not need to be cigarette smokers or be interested in smoking cessation to qualify for inclusion. Results Approximately 59% of enrolled participants were daily and non-daily cigarette smokers, and only differed from non-smoking participants on the compulsion sub-scale of the Marijuana Craving Questionnaire. Among cigarette smokers who were retained in the study, there was no change in cigarettes per day for either NAC or placebo groups during the 8-week treatment phase. Being a cigarette smoker did not appear to influence the effects of NAC on cannabis abstinence, though there was a trend in the placebo group of poorer cannabis outcomes for cigarette smokers vs. non-smokers. Conclusions No evidence was found of compensatory cigarette smoking during this cannabis cessation trial in adolescents. Further work assessing interventions to reduce both cannabis and tobacco use in this population is greatly needed. PMID:24720376

    To evaluate adolescents' responses to cigarette advertisements for different brands. Adolescents were shown one print advertisement for each of five cigarette brands (Camel, Marlboro, Kool, Benson & Hedges, and Lucky Strike). They indicated on a structured questionnaire how many times they had seen the advertisement (or one almost like it), how much they liked it, whether or not they thought it made smoking more appealing, and whether or not it made them want to smoke cigarettes of that brand. Middle school and high school classrooms, seven schools in four states in the United States (New York, Pennsylvania, Ohio, and Texas). The classrooms were selected randomly within each school. 534 adolescents in grades 6-12 (ages 11-18 years) from seven schools in four states, 54% female, 76% white. The advertisements for Camel and Marlboro were more likely than the advertisements for the other brands to be seen, to be liked, to be viewed as making smoking appealing, and to influence adolescents to want to smoke cigarettes of that brand. More than 95% of the adolescents had seen an advertisement featuring Joe Camel or the Marlboro Man at least once, and more than 50% had seen these advertisements six or more times. Nearly half believed that the Joe Camel advertisement makes smoking more appealing, and 40% believed that the Marlboro Man advertisement makes smoking more appealing. Adolescent smokers were more likely than nonsmokers to believe that the advertisements for Camel and Marlboro make smoking more appealing. The advertisements most popular among adolescents are for two of the brands they are most likely to smoke--Marlboro and Camel. The results of the study are consistent with the view that certain cigarette advertisements enhance the appeal of smoking to many adolescents.

The aim of this study was to analyze the association between the smoking status of Korean adolescents’ parents and friends and their own smoking behavior. The study assessed a nationwide sample of 72,060 middle and high students from the 10th Korea Youth Risk Behavior Web-based Survey (2014). Descriptive analysis, chi-square tests, and multiple logistic regression analysis were used to probe the association between family and friend smoking status and adolescent smoking behavior. The current cigarette smoking rates were 13.3% of boys and 4.1% of girls. The corresponding rates for electronic cigarette smoking were 4.1% and 1.5%, respectively. Higher exposure to secondhand smoke, smoking by any family member, more friends smoking, and witnessed smoking at school were associated with current smoking and electronic smoking. The smoking status of family and friends was significantly related to adolescent smoking behavior. These results should be considered in designing programs to control adolescent smoking.

    Smoking is usually initiated in adolescence, and is the leading preventable cause of death in the United States. Little is known, however, about the links between smoking and neurobiological function in adolescent smokers. This study aimed to probe prefrontal cortical function in late adolescent smokers, using a response inhibition task, and to assess possible relationships between inhibition-related brain activity, clinical features of smoking behavior, and exposure to cigarette smoking. Participants in this study were otherwise healthy late adolescent smokers (15–21 years of age; n=25), who reported daily smoking for at least the 6 months before testing, and age- and education-matched nonsmokers (16–21 years of age; n=25), who each reported smoking fewer than five cigarettes in their lifetimes. The subjects performed the Stop-signal Task, while undergoing functional magnetic resonance imaging. There were no significant group differences in prefrontal cortical activity during response inhibition, but the Heaviness of Smoking Index, a measure of smoking behavior and dependence, was negatively related to neural function in cortical regions of the smokers. These findings suggest that smoking can modulate prefrontal cortical function. Given the late development of the prefrontal cortex, which continues through adolescence, it is possible that smoking may influence the trajectory of brain development during this critical developmental period.

    There is a need to obtain greater clarity regarding adolescents' e-cigarette use and the associations of use with a wider range of risk behaviors. This study examines the associations among past-month e-cigarette use only, traditional cigarette smoking only, dual use (i.e., concurrent e-cigarette use and cigarette smoking), school-related (i.e., truancy and poor academic performance) risk behaviors, and substance-related (i.e., alcohol use, binge drinking, marijuana use, illicit drug use, and nonmedical prescription drug use) risk behaviors. Data were collected via self-administered questionnaires from a nationally representative sample of 8,696 high school seniors. An estimated 9.9% of U.S. high school seniors reported past-month e-cigarette use only, 6.0% reported past-month cigarette smoking only, and 7.3% reported past-month dual use. School- and substance-related risk behaviors had strong associations with past-month e-cigarette use. Adolescents who only used e-cigarettes had significantly greater odds of all school- and substance-related risk behaviors relative to nonusers. Dual users had significantly greater odds of frequent/daily e-cigarette use as well as all school- and substance-related risk behaviors relative to those who only used e-cigarettes. Finally, adolescents who engaged in frequent/daily e-cigarette use had significantly greater odds of binge drinking, marijuana use, other illicit drug use and nonmedical prescription drug use, relative to experimental e-cigarette users. E-cigarette use is common among U.S. adolescents, and there are robust associations between e-cigarette use and school- and substance-related risk behaviors. There is evidence that e-cigarette use clusters with risk behaviors and appears to represent a problem behavior, especially dual use of e-cigarettes and traditional cigarettes.

    To test the specificity of the association between cigarette advertising and adolescent smoking initiation. A longitudinal survey of 2102 adolescents, aged 10 to 17 years at baseline, who never smoked was conducted by using masked images of 6 cigarette advertisements and 8 other commercial products with all brand information digitally removed. The exposure variable was a combination of contact frequency and cued recall of brands for cigarette and other advertisements. Multilevel mixed-effects Poisson regressions were used to assess smoking initiation 9 months after the baseline assessment as a function of cigarette-advertisement exposure, other advertisement exposure, and baseline covariates. Thirteen percent (n = 277) of students initiated smoking during the observation period. Although the incidence of trying smoking was associated with increased exposure to cigarette advertisements (10% in the low, 12% in the medium, and 19% in the high cigarette-advertisement exposure tertile initiated smoking), exposure to other advertisements did not predict smoking initiation. Compared with low exposure to cigarette advertisements, high exposure remained a significant predictor of adolescent smoking initiation after controlling for baseline covariates (adjusted relative risk: 1.46 [95% confidence interval: 1.08-1.97]; P < .05). Our results support the notion of a content-related effect of cigarette advertisements and underlines the specificity of the relationship between tobacco marketing and teen smoking; exposure to cigarette advertisements, but not other advertisements, is associated with smoking initiation.

    Abstract : The effectiveness of outdoor smoking bans on smoking behavior among adolescents remains inconclusive. This study evaluates the long-term impact of outdoor school ground smoking bans among adolescents at secondary schools on the use of conventional cigarettes, e-cigarettes (with/without nicotine) and water pipes. Outdoor smoking bans at 19 Dutch secondary schools were evaluated using a quasi-experimental design. Data on 7733 adolescents were obtained at baseline, and at 6 and 18-month follow-up. The impact of outdoor smoking bans on 'ever use of conventional cigarettes', 'smoking onset', 'ever use of e-cigarette with nicotine', 'e-cigarette without nicotine', and 'water pipe' was measured. Multilevel logistic regression analysis was used. At schools with a ban, implementation fidelity was checked. At schools where a ban was implemented, at 18-month follow-up more adolescents had started smoking compared to the control condition. No effect of implementation of the ban was found for smoking prevalence, e-cigarettes with/without nicotine, and water pipe use. Implementation fidelity was sufficient. No long-term effects were found of an outdoor smoking ban, except for smoking onset. The ban might cause a reversal effect when schools encounter difficulties with its enforcement or when adolescents still see others smoking. Additional research is required with a longer follow-up than 18 months.

    This study examined the effect of exposure to "cigalike" (products resembling cigarettes) e-cigarette advertisements on adolescents' perceptions of cigarettes. A nationally representative sample of 802 adolescents (13-17 years old) was randomly assigned to watch three e-cigarette or three control advertisements. Never-smokers who saw the e-cigarette advertisements (n = 352) reported significantly lower perceived risks of smoking than those in the control condition (n = 320). Ever-smokers (n = 130) did not show significant differences across the conditions. In subgroup analyses, current smokers (reported smoking in the past 30 days, n = 31) in the e-cigarette condition reported significantly lower perceived benefits of smoking than those in the control condition. E-cigarette advertisements can affect adolescents' perceptions of cigarettes. Many advertisements, especially the ones promoting "cigalikes," depict e-cigarettes as being similar to cigarettes (e.g., look, flavor) but also as a solution for cigarettes' shortcomings (e.g., bad smell). While the advertisements include messages about problems posed by cigarettes, proposing e-cigarettes as a solution may decrease the perceived risks of smoking among never-smokers. It may also not be clear to adolescents whether advertisements are for cigarettes or e-cigarettes. Regulating e-cigarette advertisements to minimize adolescents' exposure may prevent potential harmful effects on never-smokers' perception of smoking.

    Cigarette smoking remains a major preventable public health problem associated with premature deaths worldwide. Adolescence is a unique developmental stage between childhood and adulthood. Smoking is a lifestyle habit acquired during adolescence and into adulthood, with its associated morbidity and mortality. It is therefore important to determine the factors associated with cigarette smoking in these adolescents in order to institute preventive measures and health policies to protect these adolescents early. This study aims to determine the prevalence of smoking, factors associated with smoking, and knowledge of the harmful effects of smoking in these adolescents. A cross-sectional study of 1120 adolescents aged 10-19 years selected from 10 secondary schools in Port Harcourt was conducted using a multistage sampling technique. The Global Youth Tobacco Survey (GYTS) core questionnaire was used to collect data from the subjects. A smoker was defined as one who had ever smoked a cigarette or who had one or two puffs, while a current smoker was defined as one who had taken a puff or smoked cigarettes in the last 30 days preceding the day of the questionnaire's completion. Eighty subjects (7.1%) were smokers. This was significantly (p=<0.001) higher in males (9.7%) than in females (4%). Thirty seven (3.3%) subjects were current smokers. The mean age at which smoking was initiated was 12.47±3.0 years. Twenty six (32.5%) of the smokers reported that they were initiated into cigarette smoking by their friends, 36 (45%) just wanted to experiment, 7 (8.8%) were influenced by media advertisements while 5 (6.3%) were due to parental exposure. Parental history of smoking and poor knowledge of cancer of the lungs as a harmful effect of smoking, was significantly (p=<0.05) associated with cigarette smoking. The prevalence of smoking in adolescents in Port Harcourt is high and is associated with parental smoking and poor knowledge of cancer of the lungs as a harmful effect. We

    The Integrated Model of Change has successfully explained the behavior change process. Cigarette smoking is a social phenomenon, which needs to be understood for devising effective preventive strategies. The study aims to apply the Integrated Model of Change to determine predictive factors of cigarette smoking behavior among school adolescents in Indonesia. A school-based cross-sectional study was designed to collect data in Banten, Indonesia. A total of 698 students from eight high schools were recruited by multi-stage cluster sampling. The association between cigarette smoking and the independent variables was examined by multiple logistic regressions. The majority of respondents (86.4%) were between the ages of 15 and 17 years (Mean=16.4 years; SD=1.01). Approximately half (48.8%) of the students ever tried a cigarette while 29.6% were current smokers. Curiosity was reported as the main reason for experimenting with cigarettes (32%). The significant factors regarding current cigarette smoking were attitude [adjusted odds ratio (AOR)=2.68], social norms (AOR=12.80), self-efficacy (AOR=15.85), and accessibility (AOR=4.39). The study revealed social influence and self-efficacy that were strongly associated with cigarette smoking can help authorities in guiding possible intervention programs for school adolescents.

    Research has shown that adults perceive that electronic cigarettes (e-cigarettes) are effective for smoking cessation, yet little is known about adolescents and young adults' perceptions of e-cigarettes for quitting cigarette smoking. This study describes middle, high school, and college students' beliefs about, and experiences with, e-cigarettes for cigarette smoking cessation. We conducted 18 focus groups (n = 127) with male and female cigarette smokers and nonsmokers in 2 public colleges, 2 high schools, and 1 middle school in Connecticut between November 2012 and April 2013. Participants discussed cigarette smoking cessation in relation to e-cigarettes. Verbatim transcripts were analyzed using thematic analysis. All participants, regardless of age and smoking status, were aware that e-cigarettes could be used for smoking cessation. College and high school participants described different methods of how e-cigarettes could be used for smoking cessation: (a) nicotine reduction followed by cessation; (b) cigarette reduction/dual use; and (c) long-term exclusive e-cigarette use. However, overall, participants did not perceive that e-cigarette use led to successful quitting experiences. Participants described positive attributes (maintenance of smoking actions, "healthier" alternative to cigarettes, and parental approval) and negative attributes (persistence of craving, maintenance of addiction) of e-cigarettes for cessation. Some college students expressed distrust of marketing of e-cigarettes for smoking cessation. Adolescent and young adult smokers and nonsmokers perceive that there are several methods of using e-cigarettes for quitting and are aware of both positive and negative aspects of the product. Future research is needed to determine the role of e-cigarettes for smoking cessation in this population. © The Author 2015.

    Tobacco smoking is a major risk factor for non-communicable diseases such as ischaemic heart disease, stroke, chronic obstructive airways disease and several cancers. There is little data about the prevalence and determinants of smoking among adolescents in southern Africa. This study aimed to determine the prevalence and determinants of cigarette smoking among adolescents in Blantyre City, Malawi. Cross-sectional data were obtained from school-going adolescents in Blantyre in 2001 using the Global Youth Tobacco Survey data collection instrument. Data were analysed to determine prevalence of current and ever cigarette smoking, and predictors of smoking. The prevalence of current smoking and ever smoking were 3.0% and 15.6%, respectively. Predictors of current tobacco smoking included male gender, having friends or parents who smoked, having been exposed to advertisements about tobacco brands on television and having seen a lot of advertisements in newspapers and magazines. School programmes that included being taught about smoking in class and a class discussion on the dangers of tobacco were not associated with reduced current smoking. Intervention programmes aiming to curb tobacco smoking among adolescents should focus on dealing also with parental smoking, peer influence and pay special attention toward male gender. School-based programmes to prevent smoking should be evaluated as some may have little impact in influencing current smoking status.

    Children of parents with substance use disorders (SUDs) have been shown to demonstrate an increased risk for cigarette smoking in adolescence. In this prospective study, we hypothesized that adolescent cigarette smoking risk would be accounted for by childhood disruptive behavior disorders and parent cigarette smoking. Preadolescent children (ages 10-12 years) of fathers with SUD considered at high average risk (HAR; n=274) and children of fathers without SUD or major psychopathology considered at low average risk (LAR; n=298) participated in structured interviews to determine mental disorder diagnoses and substance use history. Both parents were assessed. The age of onset of daily tobacco use was determined in three follow-up assessments conducted through late adolescence. Conduct disorder (CD) and parental smoking predicted earlier daily cigarette smoking, and mediated the relationship between risk status and offspring daily cigarette smoking. Through the identification of childhood characteristics predicting daily cigarette smoking in adolescence, these results may facilitate targeting of early childhood preventive interventions.

    Although the prevalence of adolescents' cigarette smoking has increased in recent decades, little is known regarding its epidemiology in certain Saudi regions, including the Madinah region. The aim of this study was to determine the prevalence and predictors of adolescent cigarette smoking in Madinah, Saudi Arabia. A school-based cross-sectional study was carried out in the Madinah region during 2013. A multistage stratified cluster sample was taken and included 3400 students (11-19 years) from 34 intermediate and secondary schools. Data concerning sociodemographic and smoking-related factors were collected using a valid and reliable self-administered questionnaire. The prevalence of smoking was estimated, and appropriate statistical analyses were performed, including univariate, predictive and multivariate regression analyses. The overall response rate was 97.7%. The prevalence of cigarette smoking in the respondents' 3322 adolescents was 15.17% (95% CI = 13.95-16.39) with significant differences in sociodemographic factors. The most important predictors were most or all friends smoking (OR = 12.5; 95% CI = 9.40-16.8). Other significant less important factors were parental smoking, belief in the harmful effects of smoking, cigarette advertisement in mass media, and pocket money. Cigarette smoking prevalence is a relatively low among adolescents in Madinah region. However, friends and parents smoking play an important role in the increased risk of smoking in the studied adolescents. These predictors must be included in any antismoking education programs targeting to this sector of population in the region.

    To investigate how family conflict contributes to the relationship between parental divorce and adolescent cigarette smoking and alcohol use. Population-based cross-sectional survey. School classrooms in Iceland in which an anonymous questionnaire was administered to respondents by supervising teachers. Participants were 7430 (81.4%) of 9124 14- to 16-year-old adolescents. Cigarette smoking and alcohol use during the last 30 days were assessed by self-report. Parental divorce was related to adolescent cigarette smoking during the last 30 days (OR = 2.12, 95% CI 1.84-2.44) when controlling for gender only, but was insignificant (OR = 1.18 95%, CI 0.99-1.44) when controlling for relationship with parents, disruptive social changes and family conflict. There was a significant relationship between parental divorce and adolescent alcohol use during last 30 days (OR = 1.66, 95% CI 1.48-1.87), controlling only for gender; however, the relationship disappeared (OR = 1.04, 95% CI 0.91-1.20) when controlling for other variables. Family conflicts are important contributors to the relationship between parental divorce and adolescent cigarette smoking and alcohol use. Conflict between parents and adolescents, but not inter-parental conflict, appears to be the most important factor in the relationship between family conflict and adolescent substance use.

    Adolescents residing in low-income public housing developments in inner-city regions may be particularly vulnerable to a variety of risk factors associated with cigarette smoking. To elucidate the aetiology of cigarette smoking among adolescents living in public housing developments. We examined predictors of smoking from four domains: background characteristics, social influences, behavioural control, and psychosocial characteristics using a sample of seventh graders (mean age 12.9 years) who reside in public housing developments in New York City (n = 624). The addresses of participants in a larger investigation of the aetiology and prevention of smoking were checked to determine if they lived in one of 335 public housing developments in New York City. All participants living in public housing developments were included in the current study. African-American and Hispanic students completed questionnaires about their cigarette use, social pressures to smoke, smoking attitudes, smoking knowledge, and smoking resistance skills. Students also provided information on demographic and behavioural control (such as church and school attendance). Logistic regression analyses indicated that social influences from friends and family members predicted smoking. Psychosocial characteristics such as advertising resistance skills, anti-smoking attitudes, and refusal skills lowered the odds of smoking. These findings suggest that smoking prevention approaches targeted at these young people should increase their awareness of social pressures to smoke, correct misperceptions about the prevalence of smoking among friends, and teach relevant psychosocial skills.

    Background Data about the predictors of smoking among adolescents in Greece are sparse. We tried to identify factors associated with current cigarette smoking among in-school adolescents in Greece in the context of GYTS study. Methods A secondary analysis of data from a questionnaire study using the Global Youth Tobacco Survey methodology was conducted to identify factors associated with smoking among adolescents in Greece. Data were collected in 2004–2005. The outcome variable was cigarette smoking within the past 30 days preceding the survey while independent variables included age, gender, parental educational status, parental smoking, perception of harmfulness of smoking, and the amount of pocket money at the adolescent's disposal. Results 6141 adolescents (51.5% males and 48.5% females) participated in the study. In multivariate analysis, cigarette smoking was associated with male gender (OR: 1.62; 95% CI: 1, 08–3.08), parental smoking (OR: 2.59; 95% CI: 1.45–5.89), and having pocket money ≥ 16 Euros (OR: 2.64; 95% CI: 1.19–5.98). Conclusion Male gender, parental smoking, and having pocket-money ≥ 16 Euros were independently associated with current smoking among Greek students. These findings could be taken into account in order to formulate a comprehensive anti-smoking strategy in Greece. PMID:18793389

    Because cigarette smoking affects the respiratory system earlier than many other systems of the human body, an attempt was made to identify objective and subjective respiratory problems among adolescent smokers. Two studies based on a pulmonary function test (PFT), respiratory symptom assessment, and other smoking-related variables were undertaken. Study 1 involved cigarette smokers (N = 18, 22% males, mean age 18.7 years) from a freshman college class who participated in an acute smoking experiment that involved performing a PFT before and after smoking a single cigarette. Study 2 was performed on a combined group of vocational-technical high school students and freshman college students (N = 44, 48% males, mean age 17.8 years) where PFT parameters, respiratory symptoms, and smoking-related health vulnerability were assessed among smokers vs nonsmokers. In Study 1, the average reduction across PFT parameters was 4.4% and the mean estimated lung age increased from 27.15 to 29.84 years. In Study 2, a consistent trend toward reduction of PFT values among smokers vs nonsmokers was observed; the mean forced expiratory volume in 1 sec/forced vital capacity ratio (90.51% vs 94.59%), peak expiratory flow rate (80.32% vs 92.06%), and flow rate of 50% of forced vital capacity (88.39% vs 102.81%) differed significantly. Significant differences in respiratory symptoms were also observed among smokers vs nonsmokers. The beginning of respiratory health disorders can be identified among adolescent smokers. These findings might provide important clues on how to improve outcomes from health care provider-based adolescent smoking cessation counseling.

    Although smoking initiation typically occurs during adolescence, most preclinical studies of tobacco use involve adult animals. Furthermore, their focus is largely on nicotine alone, even though cigarette smoke contains thousands of constituents. The present study therefore aimed to determine whether aqueous constituents in cigarette smoke affect acquisition of nicotine self-administration during adolescence in rats. Adolescent and adult male rats, aged postnatal day (P) 25 and 85, respectively, were food trained on a fixed ratio 1 (FR1) schedule, then allowed to self-administer one of 5 doses of nicotine (0, 3.75, 7.5, 15, or 30 μg/kg) or aqueous cigarette smoke extract (CSE) with equivalent nicotine content. Three progressively more difficult schedules of reinforcement, FR1, FR2, and FR5, were used. Both adolescent and adult rats acquired self-administration of nicotine and CSE. Nicotine and CSE similarly increased non-reinforced responding in adolescents, leading to enhanced overall drug intake as compared to adults. When data were corrected for age-dependent alterations in non-reinforced responding, adolescents responded more for low doses of nicotine and CSE than adults at the FR1 reinforcement schedule. No differences in adolescent responding for the two drugs were seen at this schedule, whereas adults had fewer responses for CSE than for nicotine. However, when the reinforcement schedule was increased to FR5, animals dose-dependently self-administered both nicotine and CSE, but no drug or age differences were observed. These data suggest that non-nicotine tobacco smoke constituents do not influence the reinforcing effect of nicotine in adolescents. Published by Elsevier Ltd.

    BACKGROUND: Adolescent e-cigarette use has increased rapidly in recent years, but it is unclear whether e-cigarettes are merely substituting for cigarettes or whether e-cigarettes are being used by those who would not otherwise have smoked. To understand the role of e-cigarettes in overall tobacco product use, we examine prevalence rates from Southern California adolescents over 2 decades. METHODS: The Children’s Health Study is a longitudinal study of cohorts reaching 12th grade in 1995, 1998, 2001, 2004, and 2014. Cohorts were enrolled from entire classrooms in schools in selected communities and followed prospectively through completion of secondary school. Analyses used data from grades 11 and 12 of each cohort (N = 5490). RESULTS: Among 12th-grade students, the combined adjusted prevalence of current cigarette or e-cigarette use in 2014 was 13.7%. This was substantially greater than the 9.0% adjusted prevalence of current cigarette use in 2004, before e-cigarettes were available (P = .003) and only slightly less than the 14.7% adjusted prevalence of smoking in 2001 (P = .54). Similar patterns were observed for prevalence rates in 11th grade, for rates of ever use, and among both male and female adolescents and both Hispanic and Non-Hispanic White adolescents. CONCLUSIONS: Smoking prevalence among Southern California adolescents has declined over 2 decades, but the high prevalence of combined e-cigarette or cigarette use in 2014, compared with historical Southern California smoking prevalence, suggests that e-cigarettes are not merely substituting for cigarettes and indicates that e-cigarette use is occurring in adolescents who would not otherwise have used tobacco products.

    1988-08-01

    Employing a 1-year longitudinal design, this study examined factors related to change in adolescent smoking. Predictors of smoking onset differed from predictors of continued smoking, underscoring the importance of studying factors related to adolescent smoking onset separately from mechanisms associated with changes in smoking among current smokers. Peer smoking predicted continuation of smoking after smoking initiation. Smokers received over 26 times more offers to smoke than did nonsmokers, suggesting that smokers attempting to quit need effective refusal skills to be successful. Habitual smoking was found to develop slowly, providing a substantial time window for refusal skill training and other prevention efforts. Predictors of smoking onset differed by developmental level. Peer smoking, and marijuana use were stronger predictors of smoking onset for high-school students, and number of cigarette offers predicted better among middle-school students. Parent variables were not significant predictors of later smoking. Intention to smoke was unrelated to onset and was redundant with pretest smoking behavior in predicting cessation.

    E-cigarette use by adolescents has been related to onset of cigarette smoking but there is little knowledge about the process(es) through which this occurs. Accordingly, we tested the role of cognitive and social factors for mediating the relation between e-cigarette use and smoking onset. A school-based survey was conducted with a baseline sample of 2,338 students in Hawaii (9th and 10th graders, mean age 14.7 years) who were surveyed in 2013 (Time 1, T1) and followed up 1 year later (Time 2, T2). We assessed e-cigarette use, cigarette smoking, demographic covariates, and four hypothesized mediators: smoking-related expectancies, prototypes, and peer affiliations as well as marijuana use. The primary structural modeling analysis, based on initial never-smokers, used an autoregressive model (entering T2 mediator values adjusted for T1 values) to test for mediational pathways in the relation between e-cigarette use at T1 and cigarette smoking status at T2. Results showed that e-cigarette use was related to all of the mediators and tests of indirect effects indicated that changes in expectancies, affiliations, and marijuana use were significant pathways in the relation between e-cigarette use and smoking onset. A direct effect from e-cigarette use to smoking onset was nonsignificant. Findings were replicated across autoregressive and prospective models. We conclude that the relation between adolescent e-cigarette use and smoking onset is in part attributable to cognitive and social processes that follow from e-cigarette use. Further research is needed to understand the relative role of nicotine and psychosocial factors in smoking onset. PMID:27669093

    Introduction Attention deficit/hyperactivity disorder (ADHD) is associated with health risks in adolescence which includes the potential for smoking cigarettes, early smoking initiation, and rapid progression to daily smoking. Much less is known, however, about prognostically-relevant smoking behaviors among individuals with childhood ADHD. Further research in this area is important for identifying individuals at pronounced risk for nicotine addiction, and for developing effective interventions for this population. Method This study examined initiation of cigarette smoking, progression to regular smoking, quantity of use, indicators of tobacco dependence, and quit rates among adolescents and young adults with (n=364) and without (n=240) childhood ADHD. Results Individuals with, versus without, ADHD histories were significantly more likely to become daily smokers independent of conduct disorder. They were also more likely to initiate smoking at younger ages and to progress to regular smoking more quickly. There were no significant group differences in cigarettes smoked per day, Fagerstrom Test of Nicotine Dependence or Nicotine Dependence Syndrome Scale scores or in smoking within 30 min of waking. However, smokers with ADHD reported more intense withdrawal and craving during periods of abstinence than nonADHD smokers. There were no significant group differences in number of quit attempts. Lastly, there were no significant differences among symptom persisters and desisters in daily smoking and amount. Conclusions Individuals with ADHD histories are at high risk for persistent smoking given their early onset, rapid course, and abstinence characteristics. Smoking cessation programs may need to be adapted or otherwise intensified for those with ADHD. PMID:27824233

    The popularity of electronic cigarettes (e-cigarettes) among adolescents is growing worldwide. A more accurate model than the much discussed but inadequate Gateway Hypothesis is needed to explain some adolescents' initial preference for e-cigarettes over tobacco cigarettes, as well as any transition from e-cigarettes to tobacco smoking. Our aim was to summarize the diffuse fear that adolescents will be indirectly encouraged to begin smoking tobacco via the use of e-cigarettes and to systematize the disparate causal hypotheses used thus far in relevant literature. We summarized the vague and fragmented hypotheses formulated thus far in literature on both trajectories from abstinence to e-cigarette use and from there to tobacco smoking into a set of empirically testable hypotheses and organized them into a comprehensive model. Our results indicate that the perceived health risks, specific product characteristics (such as taste, price and inconspicuous use), and higher levels of acceptance among peers and others potentially make e-cigarettes initially more attractive to adolescents than tobacco cigarettes. Later, increasing familiarity with nicotine could lead to the reevaluation of both electronic and tobacco cigarettes and subsequently to a potential transition to tobacco smoking. The suggested "catalyst model" takes variations in the nicotine content of e-cigarettes as well as the dual use of different substances into account. Our model provides causal hypotheses for the initiation of e-cigarette use and for the potential transition to tobacco smoking which, after being tested in empirical studies, could lead to the formulation of concrete recommendations for healthcare intervention and prevention measures. We developed a model that provides causal hypotheses for the initiation of e-cigarette use and for the potential transition to tobacco smoking. © The Author 2015.

    Background There has been a large migration from rural to urban areas in much of the developing world. In the past this was less true in Vietnam, which remains largely agricultural; however, since the 1990’s, economic reforms and loosening of government policies that had previously limited movement have led to a large increase in this rural to urban population movement. Risky health behaviors have been found among migrants in many other settings. The purpose of this research is to determine whether migrant adolescents and young adults in the city of Hanoi are more or less likely than local ones to engage in cigarette smoking and alcohol drinking health risk behaviors, to identify factors associated with these behaviors and to suggest interventions to reduce these health risk behaviors among the study population. Methods A cross-sectional survey of 4550 adolescents and young adults aged 15–24 was conducted in urban Hanoi in 2006. This study examines current use of cigarettes and alcohol by migration status using multivariate logistic regressions. Results Cigarette smoking and drinking alcohol are male phenomena. The prevalence of cigarette smoking and alcohol drinking is high among adolescents and young adults in Hanoi, and is more common among migrants who came from rural areas of other provinces than non-migrants in the city. However, multivariate analysis revealed that migrants were neither more likely to smoke cigarettes nor drink alcohol than non-migrants after controlling for other factors such as age, full-time worker status, depression, and having close friends who smoke and/or drink. Conclusion The results suggest that interventions aiming at smoking and/or drinking reduction should pay more attention to adolescents, especially males, changing health risk behaviors at school and at work, and peer influence than their migration status.

    Adolescence is a period of enhanced vulnerability to the motivational properties of tobacco/cigarette smoking. Several studies have suggested that smoking initiation during this period will more likely lead to long-lasting cigarette or nicotine addiction. In the present study, we investigated the influences of adolescent cigarette smoke or nicotine exposure on the rewarding effects of nicotine, particularly whether these influences persist even after a long period of abstinence. Towards this, adolescent and adult Sprague-Dawley rats were repeatedly exposed to cigarette smoke or nicotine, for 14 days, and then were subjected to a 1-month abstinence period. Thereafter, the rewarding effects of nicotine were evaluated through the conditioned place preference (CPP) and self-administration (SA) tests. Even after a 1-month abstinence period, rats pre-exposed to either nicotine or cigarette smoke demonstrated enhanced CPP for the higher dose (0.6 mg/kg) of nicotine. Notably, cigarette smoke-preexposed adolescent rats, now adults, showed CPP for both 0.2 and 0.6 mg/kg dose of nicotine. Moreover, only these rats (pre-exposed to cigarette smoke during adolescence) showed significant acquisition and maintenance of nicotine (0.03 mg/kg/infusion) SA. These results suggest that cigarette smoke exposure during adolescence enhances sensitivity to the rewarding effects of nicotine in adulthood, even after a long period of abstinence. This may be a factor in the high rates of nicotine addiction and dependence observed in smokers who started during adolescence. More importantly, our findings highlight the enduring consequences of adolescent-onset cigarette smoking and the need to protect this vulnerable population. Copyright © 2015 Elsevier Ltd.

    Reducing tobacco use among adolescents in China represents a significant challenge for global tobacco control. Existing behavioral theories developed in the West - such as the Protection Motivation Theory (PMT) - may be useful tools to help tackle this challenge. We examined the relationships between PMT factors and self-reported cigarette smoking behavior and intention among a random sample of vocational high school students (N=553) in Wuhan, China. Tobacco-related perceptions were assessed using the PMT Scale for Adolescent Smoking. Among the total sample, 45% had initiated cigarette smoking, and 25% smoked in the past month. Among those who never smoked, 15% indicated being likely or very likely to smoke in a year. Multiple regression modeling analysis indicated the significance of the seven PMT constructs, the four PMT perceptions and the two PMT pathways in predicting intention to smoke and actual smoking behavior. Overall, perceived rewards of smoking, especially intrinsic rewards, were consistently positively related to smoking intentions and behavior, and self-efficacy to avoid smoking was negatively related to smoking. The current study suggests the utility of PMT for further research examining adolescent smoking. PMT-based smoking prevention and clinical smoking cessation intervention programs should focus more on adolescents' perceived rewards from smoking and perceived efficacy of not smoking to reduce their intention to and actual use of tobacco. © 2013.

    The public health implications of e-cigarettes depend, in part, on whether e-cigarette use affects the risk of cigarette smoking. To perform a systematic review and meta-analysis of longitudinal studies that assessed initial use of e-cigarettes and subsequent cigarette smoking. PubMed, EMBASE, Cochrane Library, Web of Science, the 2016 Society for Research on Nicotine and Tobacco 22nd Annual Meeting abstracts, the 2016 Society of Behavioral Medicine 37th Annual Meeting & Scientific Sessions abstracts, and the 2016 National Institutes of Health Tobacco Regulatory Science Program Conference were searched between February 7 and February 17, 2017. The search included indexed terms and text words to capture concepts associated with e-cigarettes and traditional cigarettes in articles published from database inception to the date of the search. Longitudinal studies reporting odds ratios for cigarette smoking initiation associated with ever use of e-cigarettes or past 30-day cigarette smoking associated with past 30-day e-cigarette use. Searches yielded 6959 unique studies, of which 9 met inclusion criteria (comprising 17 389 adolescents and young adults). Study quality and risk of bias were assessed using the Newcastle-Ottawa Scale and the Risk of Bias in Non-randomized Studies of Interventions tool, respectively. Data and estimates were pooled using random-effects meta-analysis. Among baseline never cigarette smokers, cigarette smoking initiation between baseline and follow-up. Among baseline non-past 30-day cigarette smokers who were past 30-day e-cigarette users, past 30-day cigarette smoking at follow-up. Among 17 389 adolescents and young adults, the ages ranged between 14 and 30 years at baseline, and 56.0% were female. The pooled probabilities of cigarette smoking initiation were 30.4% for baseline ever e-cigarette users and 7.9% for baseline never e-cigarette users. The pooled probabilities of past 30-day cigarette smoking at follow-up were 21.5% for baseline

    The present study investigated the importance of the perceived injunctive norm to predict early adolescent cigarette smoking intentions. A total of 271 6th graders completed a survey that included perceived prevalence of friend smoking (descriptive norm), perceptions of friends’ disapproval of smoking (injunctive norm), and future smoking intentions. Participants also listed their five best friends, in which the actual injunctive norm was calculated. Results showed that smoking intentions were significantly correlated with the perceived injunctive norm but not with the actual injunctive norm. Secondly, the perceived injunctive norm predicted an additional 3.4% of variance in smoking intentions above and beyond the perceived descriptive norm. These results demonstrate the importance of the perceived injunctive norm in predicting early adolescent smoking intentions. PMID:24078745

    We investigated the use of electronic cigarettes (e-cigarettes) with traditional cigarettes among adolescents during 2014 to 2016 to identify risk factors for using e-cigarettes only, traditional cigarettes only, or both products. We used cross-sectional data from the Taiwan Global Youth Tobacco Survey, (conducted over a 3-year period by the Health Promotion Administration, Ministry of Health and Welfare, Taiwan), which is representative of tobacco use among adolescents aged 12-18 years. The outcome variable was smoking behavior. Dependent variables included gender, grade, monthly income/allowance, parents' educational level, parents' smoking status, close friends' smoking status, use of other tobacco products, contact with cigarette/e-cigarette advertisements, and access to free cigarettes/e-cigarettes. Multinomial regression identify factors influencing the smoking behaviors of adolescents, as manifested in the use of traditional cigarettes only, e-cigarettes only, e-cigarettes with traditional cigarettes, and nonsmoking. When weighted to the population, the sample included 1723150 adolescents in 2014, 1691568 adolescents in 2015, and 1627216 adolescents in 2016. The rates averaged over three years were as follows: nonsmoking (91.6%), traditional cigarettes only (5.4%), e-cigarettes only (1.5%), and dual usage (1.6%). Among adolescents in Taiwan, the following were risk factors for dual use: male, older, high monthly allowance, smoking parents, smoking friends, use of other tobacco products, contact with cigarette advertisements, and access to free cigarettes. Our results revealed an increase in the number of adolescents using e-cigarettes with traditional cigarettes. We recommend that the government continue smoking cessation programs while maintaining control over advertisements and promotions for tobacco products. This is the first study to examine the dual use of e-cigarettes and traditional cigarettes among adolescents in Taiwan. This study identified the

    One concern regarding the recent increase in adolescent e-cigarette use is the possibility that electronic (e-) cigarettes may be used by those who might not otherwise have used cigarettes, and that dual use, or transition to cigarette use alone, may follow. Questionnaire data were obtained in 2014 from 11th/12th grade students attending schools in 12 communities included in the Southern California Children's Health Study. We evaluated the cross-sectional association between e-cigarette use, the social environment (family and friends' use and approval of e-cigarettes and cigarettes), and susceptibility to future cigarette use among never cigarette smokers (N = 1,694), using previously validated measures based on reported absence of a definitive commitment not to smoke. Among adolescents who had never used cigarettes, 31.8% of past e-cigarette users and 34.6% of current (past 30-day) e-cigarette users indicated susceptibility to cigarette use, compared with 21.0% of never e-cigarette users. The odds of indicating susceptibility to cigarette use were two times higher for current e-cigarette users compared with never users (odds ratio = 1.97; 95% confidence interval: 1.21-3.22). A social environment favorable to e-cigarettes (friends' use of and positive attitudes toward the use of e-cigarettes) was also associated with greater likelihood of susceptibility to cigarette use, independent of an individual's e-cigarette use. E-cigarette use in adolescence, and a pro-e-cigarette social environment, may put adolescents at risk for future use of cigarettes. E-cigarettes may contribute to subsequent cigarette use via nicotine addiction or social normalization of smoking behaviors. Copyright © 2016 Society for Adolescent Health and Medicine.

    Electronic cigarette (e-cigarette) use now surpasses the use of conventional cigarettes among U.S. adolescents. Given the important role of physicians in preventing adolescent risk behaviors, we sought to understand how physicians communicate about e-cigarettes when counseling adolescent patients and their parents. We also explored physicians' support for regulations aimed at discouraging adolescents' e-cigarette use. A national U.S. sample of 776 pediatricians and family medicine physicians who provide primary care to adolescent patients completed an online survey in Spring 2014. Many physicians (41%) would, if asked, tell their patients that e-cigarettes are less harmful than cigarettes, and a substantial minority (24%) would recommend e-cigarettes to adolescents for smoking cessation. Most physicians reported routinely screening adolescent patients for cigarette smoking but few routinely screened for e-cigarette use (86% vs. 14%; p < .001). Routine counseling was similarly more common for avoiding cigarette smoking than for avoiding e-cigarette use (79% vs. 18%; p < .001). Support for government regulation of e-cigarettes was high, with 91% of physicians endorsing policies that prevent minors from buying e-cigarettes. Physicians infrequently screen or counsel their adolescent patients about e-cigarette use, although e-cigarettes often come up during visits. Additional efforts by physicians could help prevent future use by adolescents. Recommending e-cigarettes as a smoking cessation aid to adolescent patients is inadvisable given the lack of evidence for efficacy in that population. As federal regulation of e-cigarettes remains in limbo, pediatricians and family medicine physicians can offer a powerful voice for informing regulations aimed at reducing use by adolescents.

    The concept of “forbidden fruit” has been popularly associated with adolescent cigarette smoking in the US. However, only a few empirical studies have been conducted to investigate how this construct operates among adolescents. We examined the concurrent and prospective relationships between two related concepts of forbidden fruit and adolescent cigarette smoking behavior and intention. We found some support for forbidden fruit attitudes as concurrent and longitudinal predictors of smoking and intention to smoke. Implications of these findings are discussed. PMID:20590380

    The present study aims to investigate the longitudinal impact of situational Internet use on future cigarette smoking and alcohol use among male and female adolescents. A Northern Taiwanese cohort sample of adolescents with no prior use of cigarettes (n=1445) or alcohol (n=1468) was surveyed at age 16 and again 4 years later. Information regarding where, why, and length of time spent using the Internet was gathered from the 16-year-old participants. Outcome information regarding cigarette/alcohol use was gathered via a follow-up questionnaire at age 20. Multivariate regressions were used to incorporate peer, individual and family characteristics as measured at age 16 and create models of future cigarette and alcohol use at age 20. The analyses demonstrated that adolescent Internet use, particularly where such use took place, has a significant impact on future cigarette smoking and alcohol use, adjusted for conventional factors, and its relationship differs significantly by gender. Female adolescents with Internet café use appear to be especially likely to develop these two risky behaviors. The why of Internet use is also a predictor of future cigarette smoking. Finally, time spent using the Internet is significantly related to alcohol use; greater use of the Internet is associated with higher levels of drinking. The results revealed that different risky behaviors are differentially influenced by separate components of adolescent Internet use. These findings suggest that programs aimed at promoting adolescent health could potentially benefit Taiwanese adolescents by including components related to situational Internet use and taking gender into consideration. © 2013.

    Understanding the emotional risk factors for cigarette smoking in adolescence can greatly inform prevention efforts. The current study examined prospective relationships between three affective dimensions – negative mood variability, overall negative mood, and depression, affect-related smoking motives, and future smoking patterns among adolescents. The current study expands on prior research by using real-time methods to assess mood and by focusing on a key developmental transition in smoking behavior: the progression from experimentation or low level, infrequent use to higher use. Ninth and 10th grade students (N = 461; 55% girls) provided data on cigarette use at a baseline and follow-up 15-month wave, and also provided ecological momentary assessments of negative moods via palmtop computers for one week at each wave. Negative mood was examined via the means of negative mood reports at each wave, and mood variability was examined via the intraindividual standard deviations of negative mood reports at each wave. Depressive symptoms and smoking motives were also assessed. Findings supported a complex self-medication model of smoking escalation in adolescence whereby mood-smoking relationships differed by affect dimension and gender. For girls, greater negative mood variability at baseline significantly predicted rapid escalation in smoking over time, whereas depressive symptoms and overall negative mood were unrelated to girls’ smoking patterns. In contrast, overall negative mood significantly predicted boys’ smoking escalation among those with affect-related motives for smoking. Results thus suggest that inconsistent mood-smoking relations in past work may be driven by the complex interrelationships among affect vulnerabilities, gender, and smoking patterns. PMID:23438244

    The purpose of this study was to use individual-level data to examine the relationship between e-cigarette minimum legal sale age (MLSA) laws and cigarette smoking among U.S. adolescents, adjusting for e-cigarette use. In 2016 and 2017, we regressed (logistic) current (past 30-day) cigarette smoking (from 2009-2014 National Youth Tobacco Surveys [NYTS]) on lagged (laws enacted each year counted for the following year) and unlagged (laws enacted January-June counted for that year) state e-cigarette MLSA laws prohibiting sales to youth aged <18 or <19 years (depending on the state). Models were adjusted for year and individual- (e-cigarette and other tobacco use, sex, race/ethnicity, and age) and state-level (smoke-free laws, cigarette taxes, medical marijuana legalization, income, and unemployment) covariates. Cigarette smoking was not significantly associated with lagged MLSA laws after adjusting for year (odds ratio [OR] = .87, 95% confidence interval [CI]: .73-1.03; p = .10) and covariates (OR = .85, .69-1.03; p = .10). Unlagged laws were significantly and negatively associated with cigarette smoking (OR = .84, .71-.98, p = .02), but not after adjusting for covariates (OR = .84, .70-1.01, p = .07). E-cigarette and other tobacco use, sex, race/ethnicity, age, and smoke-free laws were associated with cigarette smoking (p <.05). Results unadjusted for e-cigarette use and other tobacco use yielded a significant negative association between e-cigarette MLSA laws and cigarette smoking (lagged: OR = .78, .64-.93, p = .01; unlagged: OR = .80, .68-.95, p = .01). After adjusting for covariates, state e-cigarette MLSA laws did not affect youth cigarette smoking. Unadjusted for e-cigarette and other tobacco use, these laws were associated with lower cigarette smoking. Copyright © 2017 The Society for Adolescent Health and Medicine. All rights reserved.

    Adolescents obtain cigarettes from both commercial and social sources. While the relationship between commercial access and adolescent smoking has been researched, no one has considered in detail whether rates of peer smoking affect cigarette availability. In two relatively deprived Scottish schools that differed in their pupil smoking rates, we assess pupil access to cigarettes. 896 13 and 15 year olds were surveyed, and 25 single-sex discussion groups held with a sub-sample of the 13 year olds. Smokers in both schools obtained cigarettes from shops, food vans and other pupils. However, pupils in the 'high' smoking school perceived greater access to both commercial and social sources, and had access to an active 'peer market'. These findings suggest that variations in cigarette access may contribute to school differences in pupil smoking rates, and that the relationship between access and adolescent smoking is circular, with greater availability increasing rates, and higher rates enhancing access.

    Little is known about age-related differences in risk factors for cigarette smoking initiation. We identified predictors of initiation in early, middle, and late adolescence from among sociodemographic factors, indicators of smoking in the social environment, psychological characteristics, lifestyle indicators, and perceived need for cigarettes. Data were drawn from a longitudinal study of 1,801 children recruited at age 10-11 years from 29 elementary schools in Montreal, Canada. Multivariable logistic regression within a generalized estimating equations framework was used to identify predictors among never smokers across three 2-year windows: age 11-13 years (n = 1,221); age 13-15 years (n = 737); and age 15-17 years (n = 690). Among the 18 risk factors investigated, two differed across age. Friends' smoking, a strong risk factor in early adolescence (odds ratio [95% confidence interval] = 5.78 [3.90-8.58]), lost potency in late adolescence (1.83 [1.31-2.57]). Depressive symptoms, a risk factor in early and middle adolescence (1.60 [1.26-2.02] and 1.92 [1.45-2.54], respectively), were inversely associated in late adolescence (.76 [.58-1.00]). Sex, TV viewing, and weight-related goals were not associated with initiation at any age. All other factors were significant in two or three age groups. Most risk factors for smoking initiation were stable across age. Tobacco control interventions may be robust for risk factors across age groups and may not need adjustment. At all ages, interventions should focus on eliminating smoking in the social environment and on reducing the availability of tobacco products.

    Background Even though the association between cigarette smoking and later substance use has been shown, there is still no compelling evidence that demonstrates the long-term effects in a high drug using community in African Americans. Few studies have examined the mediating mechanisms of the effect of adolescent cigarette smoking on the drug progression pathway. Objectives We examined the long-term influence of adolescent smoking on later illegal drug use in a cohort of urban African Americans, and the mediating role of educational attainment in the drug progression pathway. Methods The study used a longitudinal dataset from the Woodlawn Project that followed 1,242 African Americans from 1966–1967 (at age 6–7) through 2002–2003 (at age 42–43). We used the propensity score matching method to find a regular and a nonregular adolescent smoking group that had similar childhood characteristics; we used the matched sample to assess the association between adolescent smoking and drug progression, and the mediating role of educational attainment. Results Adolescent regular smokers showed significantly higher odds of using marijuana, cocaine, and heroin, having alcohol abuse problems and any drug dependence, and abuse problems in adulthood. We found that educational attainment mediated most of the drug progression pathway, including cigarette smoking, marijuana, cocaine and heroin use, and drug dependence or abuse problems in adulthood, but not alcohol abuse. Conclusions More focus needs to be put on high school dropout and development of interventions in community settings for African Americans to alter the pathway for drug progression for adolescents who use cigarettes regularly.

    Susceptibility to cigarette smoking, defined as the lack of a firm decision against smoking, is a strong predictor of regular smoking and addiction. Several modifiable risk factors have been identified among never cigarette smokers, and one potential factor of interest is waterpipe use. The purpose of this study is to determine the association of waterpipe use with susceptibility to cigarette smoking among never-smoking youth. In a pooled analysis of 17 Arab nations with nationally representative Global Youth Tobacco Surveys conducted during 2002-2011, tobacco-related information was obtained from 30,711 never-smoking adolescents representing 4,962,872 youth. Study outcome was susceptibility to cigarette smoking, and primary exposure was waterpipe use. Data were analyzed in 2014 using weighted logistic regression models, including stratified models by gender, to determine the odds of susceptibility to cigarette smoking with waterpipe use, adjusting for confounders. Overall, 20% of never-smoking youth were susceptible to cigarette smoking, ranging from 13.1% in Oman to 32.6% in Somalia; 5.2% currently used waterpipe, ranging from 0.3% in Morocco to 23.5% in Kuwait. The estimated odds of susceptibility to cigarette smoking were 2.5 (95% CI=1.9, 3.4) times higher for adolescents who used waterpipe in the past month compared with those who did not, controlling for confounders. Estimates were similar when stratified by gender. Waterpipe use is associated with susceptibility to cigarette smoking. Study findings identify a novel risk factor for never smokers to initiate smoking and will help the public health community develop and implement policies around waterpipe use prevention.

    2001-01-01

    This study examined the role of impression management in cigarette smoking by linking the constructs of self-monitoring, perceived success in impression management, self-esteem and social anxiety among nonsmokers (NS), occasional smokers (OS), and frequent smokers (FS). High school students (N=243) in years 8-12 completed a questionnaire assessing the above-mentioned variables. Multivariate discriminant function analysis and a priori contrasts were used to analyze the data. In comparison to OS, FS and NS had the lowest levels of self-monitoring, perceived success in impression management and self-esteem, while having the highest levels of social anxiety. Cigarette use may serve an impression management function during adolescence and subsequently influences OS' level of smoking. Intervention programs need to give greater consideration to providing adolescents with alternative strategies for both social acceptance and the acquisition and maintenance of self-esteem.

    Use of electronic cigarettes (e-cigarettes) is prevalent among adolescents, but there is little knowledge about the consequences of their use. We examined, longitudinally, how e-cigarette use among adolescents is related to subsequent smoking behaviour. Longitudinal school-based survey with a baseline sample of 2338 students (9th and 10th graders, mean age 14.7 years) in Hawaii surveyed in 2013 (time 1, T1) and followed up 1 year later (time 2, T2). We assessed e-cigarette use, tobacco cigarette use, and psychosocial covariates (demographics, parental support and monitoring, and sensation seeking and rebelliousness). Regression analyses including the covariates tested whether e-cigarette use was related to the onset of smoking among youth who had never smoked cigarettes, and to change in smoking frequency among youth who had previously smoked cigarettes. Among T1 never-smokers, those who had used e-cigarettes at T1 were more likely to have smoked cigarettes at T2; for a complete-case analysis, adjusted OR=2.87, 95% CI 2.03 to 4.05, p<0.0001. Among ever-smokers at T1, using e-cigarettes was not related to significant change in their frequency of smoking at T2. Uptake of e-cigarette use among T1 never-users of either product was predicted by age, Caucasian or Native Hawaiian (vs Asian-American) ethnicity, lower parental education and parental support, higher rebelliousness, and perception of e-cigarettes as healthier. Adolescents who use e-cigarettes are more likely to start smoking cigarettes. This result together with other findings suggests that policies restricting adolescents' access to e-cigarettes may have a rationale from a public health standpoint.

    Increased exposure to cigarette advertisements is associated with increases in adolescent smoking but the reasons for this association are not well established. This study evaluated whether self-concept development (operationalized as level of self-conflict) and identifying with the models used in cigarette print advertising contributed to smoking intentions among adolescents. Ninety-five adolescents (ages 11-17) participated in this two session study. In session 1, they rated the extent to which they identified with the models used in 10 current cigarette print ads (the models were isolated digitally from the cigarette advertisements) and their level of self-conflict was assessed. In session 2, participants viewed each of the 10 cigarette advertisements from which the models were drawn and rated their intentions to smoke following exposure to each ad. Model identification was associated with similar levels of post ad exposure smoking intentions for both younger and older adolescents when they also exhibited no self-conflict. A contrasting set of findings emerged for younger and older adolescents when they exhibited high levels of self-conflict: Young adolescents who strongly identified with the models used in cigarette advertisements had higher post ad exposure smoking intentions compared to younger adolescents who weakly identified with the models used in the advertisements; in contrast, older adolescents who weakly identified with the models used in cigarette advertisements had stronger post ad exposure smoking intentions compared to older adolescents who strongly identified with the models used in the advertisements. These results point to the importance of examining developmentally-relevant moderators for the effects of cigarette advertising exposure. PMID:19505768

    E-cigarette use among adolescents has increased significantly in recent years, but it remains unclear whether cigarette smoking behaviors and intentions for future cigarette smoking differ among current (i.e., 30-day) non-users, only e-cigarette users, only cigarette smokers, and dual users. A nationally representative sample of 4385 U.S. high school seniors were surveyed during the spring of their senior year via self-administered questionnaires in 2014. An estimated 9.6% of U.S. high school seniors reported current e-cigarette use only, 6.3% reported current cigarette smoking only, and 7.2% reported current dual use of e-cigarettes and cigarette smoking. There were no significant differences between current only cigarette smokers and dual users in the odds of early onset of cigarette smoking, daily cigarette smoking, intentions for future cigarette smoking, friends' cigarette smoking behaviors, attempts to quit cigarette smoking, or the inability to quit cigarette smoking. Adolescents who only used e-cigarettes had higher odds of intentions for future cigarette smoking in the next 5years (AOR=2.57, 95% CI: 1.21-5.24) than current non-users. Dual users and only cigarette smokers had higher odds of cigarette smoking behaviors and intentions for future cigarette smoking than non-users or only e-cigarette users. Adolescents who engage in current dual use have cigarette smoking behaviors and intentions for future cigarette smoking that more closely resemble cigarette smokers than e-cigarette users. Adolescents who only use e-cigarettes have higher intentions to engage in future cigarette smoking relative to their peers who do not engage in e-cigarette use or cigarette smoking.

    The present study examined smoking-specific and general parenting predictors of in vivo observed patterns of parent-adolescent discussion concerning adolescents' cigarette smoking experiences and associations between these observed patterns and 24-month longitudinal trajectories of teen cigarette smoking behavior (nonsmokers, current experimenters, escalators). Parental solicitation, adolescent disclosure, and adolescent information management were coded from direct observations of 528 video-recorded parent-adolescent discussions about cigarette smoking with 344 teens (M age = 15.62 years) with a history of smoking experimentation (321 interactions with mothers, 207 interactions with fathers). Adolescent initiation of discussions concerning their own smoking behavior (21% of interactions) was predicted by lower levels of maternal observed disapproval of cigarette smoking and fewer teen-reported communication problems with mothers. Maternal initiation in discussions (35% of interactions) was associated with higher levels of family rules about illicit substance use. Three categories of adolescent information management (full disclosure, active secrecy, incomplete strategies) were coded by matching adolescents' confidential self-reported smoking status with their observed spontaneous disclosures and responses to parental solicitations. Fully disclosing teens reported higher quality communication with their mothers (more open, less problematic). Teens engaged in active secrecy with their mothers when families had high levels of parental rules about illicit substance use and when mothers expressed lower levels of expectancies that their teen would smoke in the future. Adolescents were more likely to escalate their smoking over 2 years if their parents initiated the discussion of adolescent smoking behavior (solicited) and if adolescents engaged in active secrecy.

    The purpose of the present study was to investigate the longitudinal relation between internalizing problem behaviors (measured with the anxious/depressed and somatic complaints subscales of the Achenbach Teacher's Report Form) and self-reported cigarette smoking behavior and intentions during early adolescence. In addition, a possible mediating role of perceived harm was investigated. Sixth graders and their teachers were surveyed in the sixth grade and students were surveyed again in the seventh grade. Smoking behavior and intentions were assessed with five items including lifetime use, 30-day use, tobacco user status (nonsmoker to heavy smoker), and two intentions/behavioral expectations items. In addition to perceived harm from smoking, reasons for smoking and reasons for not smoking were included on the survey. As hypothesized, teacher reports of sixth-grade internalizing problem behaviors were negatively related to seventh-grade smoking behavior and intentions. Moreover, perceived harm from smoking was negatively related to smoking and intentions. The hypothesized mediating role of perceived harm in the internalizing to smoking relationship was not supported. Potential differences in the relation between internalizing and smoking across adolescence are discussed. Specifically, the results of the present study and an examination of prior literature suggest that in early adolescence internalizing problems are negatively related to cigarette smoking, whereas in middle and late adolescence the opposite is true.

    Research indicates that electronic cigarette (e-cigarette) use (vaping) among adolescents is associated with the initiation and progression of combustible cigarette smoking. The reasons for this association are unknown. To evaluate whether use of e-cigarettes with higher nicotine concentrations is associated with subsequent increases in the frequency and intensity of combustible cigarette smoking and vaping. In this prospective cohort study involving students from 10 high schools in the Los Angeles, California, metropolitan area, surveys were administered during 10th grade in the spring (baseline) and 11th grade in the fall (6-month follow-up) of 2015 to students who reported using e-cigarettes within the past 30 days and the nicotine concentration level they used at baseline. Self-report of baseline e-cigarette nicotine concentration of none (0 mg/mL), low (1-5 mg/mL), medium (6-17 mg/mL), or high (≥18 mg/mL) typically used during the past 30 days. Frequency of combustible cigarette smoking and e-cigarette use within the past 30 days (0 days [none], 1-2 days [infrequent], or ≥3 days [frequent]) and daily intensity of smoking and vaping (number of cigarettes smoked per day, number of vaping episodes per day, and number of puffs per vaping episode) at the 6-month follow-up. The analytic sample included 181 students (96 boys [53.0%] and 85 girls [47.0%]; mean [SD] age, 16.1 [0.4] years). Each successive increase in nicotine concentration (none to low, low to medium, and medium to high) vaped was associated with a 2.26 (95% CI, 1.28-3.98) increase in the odds of frequent (vs no) smoking and a 1.65 (95% CI, 1.09-2.51) increase in the odds of frequent (vs no) vaping at follow-up after adjustment for baseline frequency of smoking and vaping and other relevant covariates. Use of e-cigarettes with high (vs no) nicotine concentration was associated with a greater number of cigarettes smoked per day at follow-up (adjusted rate ratio [RR], 7.03; 95% CI, 6.11-7.95). An

    Tobacco use is the leading cause of noncommunicable disease morbidity and mortality. Most smokers initiate the smoking habit as adolescents or young adults. Survey data from the 2007 Lusaka (Zambia) Global Youth Tobacco Survey were used to estimate the prevalence of current cigarette smoking and assess whether exposure to pro-tobacco media and perception of the potential harm of secondhand smoke are associated with adolescents' smoking. Logistic regression analysis was used to estimate the associations. Altogether, 2378 students, of whom 56.8% were females, participated in the study. Overall, 10.5% of the students (9.3% among males and 12.1% among females) smoked cigarettes in the 30 days prior to the survey. Students who favored banning smoking in public places were 33% (OR = 0.67; 95% CI [0.47, 0.96]) less likely to smoke cigarettes compared to those who were not in favor of the ban. Seeing actors smoking in TV shows, videos or movies was positively associated with smoking (OR = 1.90; 95% CI [1.26, 2.88]). However, possessing an item with a cigarette brand logo on it, seeing advertisements of cigarettes on billboards and being ever offered a free cigarette by a cigarette sales representative were negatively associated with smoking (OR=0.39, 95% CI [0.26, 0.58]; OR=0.63, 95% CI [0.43, 0.92]; and OR=0.43, 95% CI [0.29, 0.65], respectively). Findings from this study indicate that TV advertisement-promotion-sponsorship was positively associated with smoking, while it was the opposite with other forms of advertisement; there is a need for further studies.

    Electronic cigarettes (e-cigarettes) are an emerging phenomenon that is becoming increasingly popular among adolescents. Current e-cigarette use among adolescents has more than doubled in the past few years nationally and more than tripled in Hawai‘i, despite the fact that safety in terms of health and injury from use is widely unknown. The use of e-cigarettes among adolescents is of particular concern because they may act as a gateway to smoking conventional tobacco cigarettes, substitute for cigarettes where smoking would normally not be allowed, and weaken the effect of clean air policies, and displace effective smoking cessation treatments. Additionally, the use of e-cigarettes may lead to the use of conventional cigarettes. There is special concern that e-cigarette companies are recruiting adolescents who would not have otherwise tried smoking by using tactics such as offering e-cigarettes in attractive flavorings and using the same successful strategies to market their product as tobacco companies have used for conventional cigarettes in past decades. It has been shown that exposure to cigarette marketing is related to initiation and progression in adolescent smoking. Yet, there remains no regulation on the marketing of e-cigarettes to adolescents. It can be extrapolated that expanded regulation that includes limits on the marketing of e-cigarettes may help decrease use among adolescents and prevent the possible increase of smoking rates.

    Electronic cigarette smoking is gaining dramatic popularity and is steadily spreading among the adolescents, high income, urban population around the world. The aim of this study is to highlight the hazards of e-cigarette smoking on human health. In this study, we identified 38 published studies through a systematic database searches including ISI-web of science and pub-med. We searched the related literature by using the key words including Electronic cigarette, E-cigarette, E-vapers, incidence, hazards. Studies in which electronic cigarette smoking hazards was investigated were included in the study. No limitations on publication status, study design of publication were implemented. Finally we included 28 publications and remaining 10 were excluded. E-smoking can cause, nausea, vomiting, headache, dizziness, choking, burn injuries, upper respiratory tract irritation, dry cough, dryness of the eyes and mucous membrane, release of cytokines and pro-inflammatory mediators, allergic airway inflammation, decreased exhaled nitric oxide (FeNO) synthesis in the lungs, change in bronchial gene expression and risk of lung cancer. Electronic cigarettes are swiftly promoted as an alternative to conventional cigarette smoking, although its use is highly controversial. Electronic cigarettes are not a smoking cessation product. Non-scientific claims about e-cigarettes are creating confusion in public perception about e-cigarette and people believe that e-cigarettes are safe and less addictive, but its use is unsafe and hazardous to human health. E-cigarette smoking should be regulated in the same way as traditional cigarettes and must be prohibited to children and adolescents.

    The present study examined the extent and sources of discrepancies between self-reported cigarette smoking and salivary cotinine concentration among adolescents. The data are from household interviews with a cohort of 1,024 adolescents from an urban school system. Histories of tobacco use in the last 7 days and saliva samples were obtained. Logistic regressions identified correlates of three inconsistent patterns: (a) Pattern 1-self-reported nonsmoking among adolescents with cotinine concentration above the 11.4 ng/mg cutpoint (n = 176), (b) Pattern 2-low cotinine concentration (below cutpoint) among adolescents reporting having smoked within the last 3 days (n = 155), and (c) Pattern 3-high cotinine concentration (above cutpoint) among adolescents reporting not having smoked within the last 3 days (n = 869). Rates of inconsistency were high among smokers defined by cotinine levels or self-reports (Pattern 1 = 49.1%; Pattern 2 = 42.0%). Controlling for other covariates, we found that reports of nonsmoking among those with high cotinine (Pattern 1) were associated with younger age, having few friends smoking, little recent exposure to smokers, and being interviewed by the same interviewer as the parent and on the same day. Low cotinine concentration among self-reported smokers (Pattern 2) was negatively associated with older age, being African American, number of cigarettes smoked, depth of inhalation, and exposure to passive smoke but positively associated with less recent smoking and depressive symptoms. High cotinine concentrations among self-reported nonsmokers was positively associated with exposure to passive smoke (Pattern 3). The data are consonant with laboratory findings regarding ethnic differences in nicotine metabolism rate. The inverse relationship of cotinine concentration with depressive symptoms has not previously been reported. Depressed adolescent smokers may take in smaller doses of nicotine than nondepressed smokers; alternatively, depressed

    The purpose of this study was to identify distinct trajectories of cigarette smoking from ages 14 to 32, and to examine adolescent personality factors that distinguish trajectories of smoking behavior. Participants (N=975) were randomly selected and followed prospectively since 1975. Follow-up data on cigarette use and personality and behavioral attributes were collected at five points in time, using structured interviews given in private by trained interviewers. Of these subjects, 746 comprised the cohort used in this study. Growth mixture modeling identified five smoking trajectory groups: nonsmokers, occasional smokers, late starters, quitters, and heavy/continuous smokers. Adolescent personality and behavioral risk factors such as lower ego integration, more externalizing behavior, and lower educational aspirations distinguished the trajectory groups. No gender differences were noted. The findings supported the hypotheses indicating multiple distinct trajectory groups of smoking behavior. Smoking behavior appeared in early adolescence and most often continued into adulthood. Emotional difficulties (i.e., lower ego integration), externalizing behavior, and lower educational aspirations in early adolescence were associated both with smoking at an early age and with continuing to smoke into the thirties. To be more effective, smoking prevention programs should target personality and behavioral variations, before smoking becomes habitual, particularly focused on characteristics reflecting behavioral problems as manifested in emotional difficulties, externalizing behavior, and low educational aspirations in early adolescence. The implications for research, prevention, and treatment are discussed. PMID:18686175

    To enhance our knowledge on why adolescents with a chronic condition (insulin-dependent diabetes mellitus, IDDM) choose to smoke despite possible awareness of health risks. Twelve patients aged 15-20 with IDDM who smoked cigarettes volunteered to participate in qualitative interviews. The results were analyzed with content analysis according to Miles and Huberman 1994. One set confirmed what is earlier known on cigarette smoking among adolescents, such as plain exploring, needs to conform with group norms, identity needs and denial of risks. Other themes gave new insights. One was the emotional attitudes-or lack of emotions-expressed by important others, which exerted strong influences on the smoking trajectories. These emotions affected both initiation and motivation for quitting cigarette smoking and seemed crucial as means of meaningful communications concerning smoking. One theme was a flow path of cigarette smoking, which demonstrated opportunities for secondary prevention. Finally, developmental reasons for smoking and motivation for quitting could be described. There are several windows of opportunities to lower the risk of adolescents with IDDM and other chronic conditions from becoming and remaining smokers, as reported by young people themselves.

    Objective Use of electronic cigarettes (e-cigarettes) is prevalent among adolescents, but there is little knowledge about the consequences of their use. We examined, longitudinally, how e-cigarette use among adolescents is related to subsequent smoking behaviour. Methods Longitudinal school-based survey with a baseline sample of 2338 students (9th and 10th graders, mean age 14.7 years) in Hawaii surveyed in 2013 (time 1, T1) and followed up 1 year later (time 2, T2). We assessed e-cigarette use, tobacco cigarette use, and psychosocial covariates (demographics, parental support and monitoring, and sensation seeking and rebelliousness). Regression analyses including the covariates tested whether e-cigarette use was related to the onset of smoking among youth who had never smoked cigarettes, and to change in smoking frequency among youth who had previously smoked cigarettes. Results Among T1 never-smokers, those who had used e-cigarettes at T1 were more likely to have smoked cigarettes at T2; for a complete-case analysis, adjusted OR=2.87, 95% CI 2.03 to 4.05, p<0.0001. Among ever-smokers at T1, using e-cigarettes was not related to significant change in their frequency of smoking at T2. Uptake of e-cigarette use among T1 never-users of either product was predicted by age, Caucasian or Native Hawaiian (vs Asian-American) ethnicity, lower parental education and parental support, higher rebelliousness and perception of e-cigarettes as healthier. Conclusions Adolescents who use e-cigarettes are more likely to start smoking cigarettes. This result together with other findings suggests that policies restricting adolescents’ access to e-cigarettes may have a rationale from a public health standpoint. PMID:26811353

    This article explored the relationship between physical activity and smoking behavior among adolescents using rich longitudinal survey data from a nationally representative sample of adolescents. Several endogeneity-corrected models were estimated to ascertain the effect of exercise on both the probability of being a smoker and the intensity of cigarette smoking. The analysis indicated that 1 additional weekly occurrence of exercise led to a 0.3% decline in the probability of being a smoker and led to a 4.1% reduction in the number of cigarettes smoked by a smoker during a month, a result that was robust to stratification by gender and race/ethnicity. Consistent with the national guidelines, frequencies of physical activity of at least 7 times per week appeared to exhibit the biggest benefits in terms of reduction in smoking for both genders and across races/ethnicities. Reduction in health-damaging smoking behavior among adolescents could be an additional benefit of being physically active. This research documented a new pathway by which even moderate increases in physical activity could result in improved health outcomes by reducing smoking. © The Author 2014.

    E-cigarette use is rapidly increasing among adolescents in the United States, with some suggesting that e-cigarettes are the cause of declining youth cigarette smoking. We hypothesized that the decline in youth smoking changed after e-cigarettes arrived on the US market in 2007. Data were collected by using cross-sectional, nationally representative school-based samples of sixth- through 12th-graders from 2004-2014 National Youth Tobacco Surveys (samples ranged from 16 614 in 2013 to 25 324 in 2004). Analyses were conducted by using interrupted time series of ever (≥1 puff) and current (last 30 days) cigarette smoking. Logistic regression was used to identify psychosocial risk factors associated with cigarette smoking in the 2004-2009 samples; this model was then applied to estimate the probability of cigarette smoking among cigarette smokers and e-cigarette users in the 2011-2014 samples. Youth cigarette smoking decreased linearly between 2004 and 2014 (P = .009 for ever smoking and P = .05 for current smoking), with no significant change in this trend after 2009 (P = .57 and .23). Based on the psychosocial model of smoking, including demographic characteristics, willingness to wear clothing with a tobacco logo, living with a smoker, likelihood of smoking in the next year, likelihood of smoking cigarettes from a friend, and use of tobacco products other than cigarettes or e-cigarettes, the model categorized <25% of current e-cigarette-only users (between 11.0% in 2012 and 23.1% in 2013) as current smokers. The introduction of e-cigarettes was not associated with a change in the linear decline in cigarette smoking among youth. E-cigarette-only users would be unlikely to have initiated tobacco product use with cigarettes. Copyright © 2017 by the American Academy of Pediatrics.

    In addition to individual-level characteristics, the social and physical environment may influence the initiation of cigarette smoking in adolescents. The objective of this paper is to describe the association between smoking intolerance in schools, and in restaurants and corner stores located near schools, and initiation of cigarette smoking among adolescents. Data on cigarette smoking were collected in self-report questionnaires every 3 months from 1999 to 2005 in a sample of 1,293 Grade 7 students in 10 secondary schools in Montreal, Canada. Baseline never-smokers (n = 868) were retained for analysis. School administrators completed questionnaires on tobacco control policies and activities within schools. Data on access to tobacco products and smoking restrictions in restaurants and corner stores located in school neighborhoods were collected through direct observation. Schools, restaurants, and corner stores were classified as smoking tolerant or intolerant. Time to initiation of cigarette smoking was modeled as a function of smoking intolerance in schools, restaurants, and corner stores in survival analyses (Cox proportional hazards modeling). Students in smoking-intolerant schools were less likely to initiate smoking than students in smoking-tolerant schools (hazard ratio [HR; 95% CI] = 0.83 [0.68, 1.01]). Students attending schools located in neighborhoods with smoking-intolerant restaurants were less likely to initiate smoking (HR [95% CI] = 0.85 [0.68, 1.07]). There was no association between corner store smoking intolerance and initiation. Smoking intolerance in schools and restaurants may protect against initiation of cigarette smoking and could be useful targets for more intense tobacco control efforts.

    As elsewhere, in South Korea electronic cigarettes (e-cigarettes) are marketed, in part, as a smoking cessation aid. We assessed the prevalence of e-cigarette use among Korean adolescents and the relationship between e-cigarette use and current (past 30-day) smoking, cigarettes/day, attempts to quit conventional cigarettes, and ceasing to use cigarettes. Data from the 2011 Korean Youth Risk Behavior Web-based Survey of 75,643 students aged 13-18 years were analyzed with logistic regression. A total of 9.4% (8.0% ever-dual users who were concurrently using e-cigarettes and smoking conventional cigarettes and 1.4% ever-e-cigarette only users) of Korean adolescents have ever used e-cigarettes and 4.7% were current (past 30-day) e-cigarette users (3.6% dual users and 1.1% e-cigarettes only). After adjusting for demographics, current cigarette smokers were much more likely to use e-cigarettes than were nonsmokers. Among current cigarette smokers, those who smoked more frequently were more likely to be current e-cigarette users. The odds of being an e-cigarette user were 1.58 times (95% confidence interval, 1.39-1.79) higher among students who had made an attempt to quit than for those who had not. It was rare for students no longer using cigarettes to be among current e-cigarette users (odds ratio, .10; confidence interval, .09-.12). Some Korean adolescents may be responding to advertising claims that e-cigarettes are a cessation aid: those who had made an attempt to quit were more likely to use e-cigarettes but less likely to no longer use cigarettes. E-cigarette use was strongly associated with current and heavier cigarette smoking. Copyright © 2014 Society for Adolescent Health and Medicine. Published by Elsevier Inc. All rights reserved.

    Tobacco marketing has expanded from cigarettes to other tobacco products through many promotional channels. Marketing exposure is associated with use of that tobacco product. However, it's unclear if marketing for one product leads to subsequent use of other tobacco products. This prospective cohort study assessed self-reported marketing exposure for six tobacco products across five marketing channels in 11th/12th grade students in 2014. Approximately 16 months later a follow-up survey was conducted online (N=1553) to assess initiation of cigarettes, e-cigarettes and hookah. Adolescent never smokers with frequent exposure to cigarette marketing on the Internet and in stores are more than two times as likely to begin smoking as young adults (Internet OR 2.98 [95% CI, 1.56-5.66); Stores OR, 2.83 [95% CI, 1.23-6.50]). Never users of e-cigarettes were significantly more likely to initiate use, if exposed to Internet, store and outdoor e-cigarette marketing. Never users of hookah were more likely to use hookah after seeing it marketed in stores. Youth exposed to marketing of e-cigarettes, hookah, cigars, smokeless and pipe tobacco in stores were two to three times more likely to begin smoking cigarettes even though the marketed products were not cigarettes. Adolescent exposure to marketing of tobacco products is associated with initiation of those products as young adults. Exposure to marketing for non-cigarette tobacco products is associated with subsequent cigarette smoking, even when the promoted products are not cigarettes. Future research and interventions should consider the influence of marketing from multiple tobacco products on adolescent tobacco use. Adolescents grow up in a rich media environment with exposure to tobacco marketing in both their homes (e.g., through the Internet and television) and their communities (e.g., stores and billboards). This prospective study provides evidence that adolescents exposed to tobacco marketing for multiple tobacco

    Cigarette smoking is considered the most important preventable public health problem in developed countries, especially among adolescents. To determine the prevalence of cigarette smoking and associated factors in high school adolescents, from a Colombian city. The self-administered global tobacco youth survey (GTYS) was answered by 831 teenagers aged 14 ± 2 years (54% females). For data analysis, proportions were calculated; for associations, binary and multivariable logistic regression was applied. Fourteen percent of respondents declared that they had consumed at least one cigarette during the last 30 days. The life-time prevalence of tobacco use was 27.1%. Being older than thirteen years old, father’s academic level and having a smoker mother were factors associated with smoking. The prevalence of smoking in these adolescents was high. Age over 13 years and a smoking mother were associated with the cigarette smoking.

    The objective of this study was to examine the smoking behavior among adolescents in Thailand and Malaysia. Population-based, national surveys were conducted among 1,704 adolescents between the ages of 13 and 18 from Thailand (n = 927) and Malaysia (n = 777). Respondents were selected using multistage cluster sampling. Respondents were asked to complete self-administered questionnaires. Approximately 5% of Thai and Malaysian adolescents were current smokers, while an additional 8.6% of Thai and 8.1% of Malaysian adolescents reported being beginning smokers. On average, Thai smokers reported first smoking a whole cigarette at 14.6 years old (SD = 1.9), while Malaysian smokers at age 13.9 years (SD = 2.2). More than half of Thai smokers (60.4%) reported they bought cigarettes themselves and 29.9% got cigarettes from friends. In Malaysia, most smokers (68.3%) reported they bought cigarettes themselves, only 20.7% got cigarettes from friends. Seventy-six percent of Thai adolescent smokers smoked factory-made brands as their usual brand compared to 27.7% of Malaysian adolescent smokers. Eight percent of Thai adolescents and 10% of Malaysian adolescents reported smoking hand-rolled cigarettes. Approximately half of Thais and more than 40% of Malaysian smokers reported they tried to quit smoking within the past month. The smoking prevalence of Thai adolescents is close to that of Malaysian adolescents. Factory-made cigarette consumption is an important problem in Thai adolescents and needs to be targeted.

    While the heritability of cigarette smoking and nicotine dependence (ND) is well-documented, the contribution of specific genetic variants to specific phenotypes has not been closely examined. The objectives of this study were to test the associations between 321 tagging single-nucleotide polymorphisms (SNPs) that capture common genetic variation in 24 genes, and early smoking and ND phenotypes in novice adolescent smokers, and to assess if genetic predictors differ across these phenotypes. In a prospective study of 1294 adolescents aged 12-13 years recruited from ten Montreal-area secondary schools, 544 participants who had smoked at least once during the 7-8 year follow-up provided DNA. 321 single-nucleotide polymorphisms (SNPs) in 24 candidate genes were tested for an association with number of cigarettes smoked in the past 3 months, and with five ND phenotypes (a modified version of the Fagerstrom Tolerance Questionnaire, the ICD-10 and three clusters of ND symptoms representing withdrawal symptoms, use of nicotine for self-medication, and a general ND/craving symptom indicator). The pattern of SNP-gene associations differed across phenotypes. Sixteen SNPs in seven genes (ANKK1, CHRNA7, DDC, DRD2, COMT, OPRM1, SLC6A3 (also known as DAT1)) were associated with at least one phenotype with a p-value <0.01 using linear mixed models. After permutation and FDR adjustment, none of the associations remained statistically significant, although the p-values for the association between rs557748 in OPRM1 and the ND/craving and self-medication phenotypes were both 0.076. Because the genetic predictors differ, specific cigarette smoking and ND phenotypes should be distinguished in genetic studies in adolescents. Fifteen of the 16 top-ranked SNPs identified in this study were from loci involved in dopaminergic pathways (ANKK1/DRD2, DDC, COMT, OPRM1, and SLC6A3). Dopaminergic pathways may be salient during early smoking and the development of ND.

    Although adolescents are a group heavily targeted by the e-cigarette industry, research in cue-reactivity has not previously examined adolescents' behavioral and neural responses to e-cigarette advertising. This study addressed this gap through two experiments. In Experiment One, adult traditional cigarette smokers (n = 41) and non-smokers (n = 41) answered questions about e-cigarette and neutral advertising images. The 40 e-cigarette advertising images that most increased desire to use the product were matched to 40 neutral advertising images with similar content. In Experiment Two, the 80 advertising images selected in Experiment One were presented to adolescents (n = 30) during an functional magnetic resonance imaging brain scan. There was a range of traditional cigarette smoking across the sample with some adolescents engaging in daily smoking and others who had never smoked. Adolescents self-reported that viewing the e-cigarette advertising images increased their desire to smoke. Additionally, all participants regardless of smoking statuses showed significantly greater brain activation to e-cigarette advertisements in areas associated with cognitive control (left middle frontal gyrus), reward (right medial frontal gyrus), visual processing/attention (left lingual gyrus/fusiform gyrus, right inferior parietal lobule, left posterior cingulate, left angular gyrus) and memory (right parahippocampus, left insula). Further, an exploratory analysis showed that compared with age-matched non-smokers (n = 7), adolescent smokers (n = 7) displayed significantly greater neural activation to e-cigarette advertising images in the left inferior temporal gyrus/fusiform gyrus, compared with their responses to neutral advertising images. Overall, participants' brain responses to e-cigarette advertisements suggest a need to further investigate the long-run impact of e-cigarette advertising on adolescents. © 2017 Society for the Study of Addiction.

    Adolescent sports participants are less likely to smoke cigarettes, and sports participation may prevent young people from smoking. Research suggests that the relationship between sports participation and smoking may vary by race/ethnicity and is also possibly moderated by exposure to peer smoking. We investigated these relationships in a sample of 311 adolescents ages 13 – 21 presenting for well-visit medical appointments. Participants completed valid assessments of demographics, sports participation, exposure to peer smoking, and smoking behavior. The primary outcome was smoking status (never smoked, tried smoking, experimental/current smoker). Ordinal logistic regression was used separately for non-Hispanic White (n = 122) and non-White (n = 189; 70.4% Black, 14.3% Hispanic, and 15.3% other) adolescents. Among White adolescents, sports participants had significantly lower odds of smoking than non-sports participants, independent of age, gender, and peer smoking. For non-Whites, the adjusted effect of sports participation on smoking depended upon exposure to peers who smoke. Compared with non-sport participants with no exposure to peer smoking, sports participants with no exposure to peer smoking had significantly lower odds of smoking, whereas sports participants with exposure to peer smoking had significantly higher odds of smoking. Sports appear to be protective against smoking among non-Hispanic White adolescents, but among non-White adolescents exposure to peer smoking influences this protection. Interventions incorporating sports to prevent smoking should consider these racial/ethnic differences to address disparities in smoking-related disease. PMID:22698897

    This study examined the changes in friends' and parental influences on cigarette smoking across two developmentally distinct social environments for adolescents: junior high school and high school. Longitudinal data consisting of seven repeated measures following 1,001 adolescents from 7th to 12th grade was obtained from the Midwestern Prevention Project. A two-piece Growth Curve Model (GCM) was used to assess the growth trajectory of current cigarette use: one piece for the junior high school period, and the other for the high school period. Perceived friends' and parental cigarette use were each used as a time-varying covariate in separate GCMs. Effects of friends' and parental cigarette use remained significant on adolescent cigarette smoking across the two developmental periods. The magnitude of friends' effect was in general higher during junior high school than high school. The magnitude of the parental effect remained relatively stable between the two periods. However, decreasing trends in both effects were observed from 10th to 12th grade. Gender differences also emerged. Friends' and parental effects were greater for girls in their early high school years, whereas friends' effect decreased in magnitude among girls and increased among boys during high school. The transition from junior high school to high school represents an opportunity for interventions to counteract peer influence given that such influence appeared to be much weaker during this period. However, interventions should continue to target parents as their behavior remains influential through the end of high school. Copyright © 2013 Society for Adolescent Health and Medicine.

    BACKGROUND: E-cigarette use is rapidly increasing among adolescents in the United States, with some suggesting that e-cigarettes are the cause of declining youth cigarette smoking. We hypothesized that the decline in youth smoking changed after e-cigarettes arrived on the US market in 2007. METHODS: Data were collected by using cross-sectional, nationally representative school-based samples of sixth- through 12th-graders from 2004–2014 National Youth Tobacco Surveys (samples ranged from 16 614 in 2013 to 25 324 in 2004). Analyses were conducted by using interrupted time series of ever (≥1 puff) and current (last 30 days) cigarette smoking. Logistic regression was used to identify psychosocial risk factors associated with cigarette smoking in the 2004–2009 samples; this model was then applied to estimate the probability of cigarette smoking among cigarette smokers and e-cigarette users in the 2011–2014 samples. RESULTS: Youth cigarette smoking decreased linearly between 2004 and 2014 (P = .009 for ever smoking and P = .05 for current smoking), with no significant change in this trend after 2009 (P = .57 and .23). Based on the psychosocial model of smoking, including demographic characteristics, willingness to wear clothing with a tobacco logo, living with a smoker, likelihood of smoking in the next year, likelihood of smoking cigarettes from a friend, and use of tobacco products other than cigarettes or e-cigarettes, the model categorized <25% of current e-cigarette–only users (between 11.0% in 2012 and 23.1% in 2013) as current smokers. CONCLUSIONS: The introduction of e-cigarettes was not associated with a change in the linear decline in cigarette smoking among youth. E-cigarette–only users would be unlikely to have initiated tobacco product use with cigarettes. PMID:28115540

    Previous studies have demonstrated the influence of parental (both mother and father) cigarette smoking on adolescents' cigarette smoking. Little is known, however, about how parental tobacco use is related to waterpipe and dual waterpipe/cigarette use, which is increasing dramatically in the Arab countries. Study data (n = 34 788, N = 6 109 572) were obtained from nationally representative Global Youth Tobacco Surveys in 17 Arab countries. Study outcome was adolescents' tobacco use categorized into none, cigarette smoking only, waterpipe smoking (WPS) only, and dual use. Primary exposure included parental tobacco use categorized into 10 groups-maternal (mother) cigarette smoking only, maternal WPS only, maternal dual use, paternal (father) cigarette smoking only, paternal WPS only, paternal dual use, parental (both mother and father) cigarette smoking only, parental WPS only, parental dual use, and none. Weighted multinomial regression models were conducted to assess the relationships. Adolescents reported smoking WPS only (5.7%), cigarettes only (2.9%), and dual use (3.5%). Compared to adolescent with no exposure to parental tobacco use, adolescent exposure to parental dual use was associated with significant increase in WPS only (OR = 6.08, 95% CI = 2.38-15.51) and dual use (OR = 3.86, 95% CI = 1.43-10.43). Effect modification of the relationship by adolescents' sex was observed. This is the first study to examine adolescent cigarette, waterpipe, and dual use with parental tobacco use. Study findings may help development of cessation interventions targeting parental tobacco use to prevent the rising waterpipe and dual use strain of the global tobacco epidemic.

    Little is known about risk factors that are associated with e-cigarette use in adolescents. Multilevel mixed-effects regressions were performed to assess the relationship between factors that might be associated with e-cigarette, conventional cigarette and dual use in a cohort of 2693 German adolescents (mean age=12.5 years; SD=0.6). Risk factors were assessed in October 2010 and life time e-cigarette and conventional cigarette use were assessed 26 months later. Use of e-cigarettes as well as use of conventional cigarette and dual use were associated with higher sensation seeking scores, and higher odds of having friends and parents who smoke conventional cigarettes, with conventional cigarette use additionally with male gender, being older, having higher odds of siblings who smoke conventional cigarettes, and less likely for adolescents who attend a Gymnasium, secondary school with a strong emphasis on academic learning. The use of conventional cigarettes at baseline did not predict e-cigarette use at follow-up. Lifetime prevalence of e-cigarette use was 4.7%, of conventional cigarette use 18.4%. A quarter of e-cigarette users (23.8%) never smoked a conventional cigarette. Data indicate that e-cigarette and conventional cigarette use share many but not all risk factors. E-cigarettes could counteract the process of denormalization of smoking. Copyright © 2015 Elsevier Inc. All rights reserved.

    Bullying involvement has been linked with substance use; however, less is known about its relationship with pre-initiation stages of adolescent cigarette smoking behavior. This study examined the association between bullying involvement and smoking susceptibility among never tried or experimented with cigarette smoking students. Susceptibility to cigarette smoking in adolescence is a strong predictor of subsequent smoking initiation. A cross-sectional data on Canadian adolescent and youth were drawn from the 2012/2013 Youth Smoking Survey (n=28,843). Logistic regression analysis was used to examine the association between bullying and smoking susceptibility among never-smoking students. About 21% self-reported involvement in bullying (as a bully, victim or both). Middle school students (grades 6-8) reported more involvement in bullying (24%) than those in grades 9-12 (16%). The multivariable analyses showed that the association between bullying and smoking susceptibility was significantly different by grade level. Middle school students involved in bullying had higher odds of smoking susceptibility compared to uninvolved students (bully, adjusted odds ratio [AOR]=2.54, 95% CI=1.73-3.74; victim, AOR=1.29, 95% CI=1.11-1.48; bully-victim, AOR=2.19, 95% CI=1.75-2.74). There were no significant associations between all subgroups of bullying and smoking susceptibility for grades 9-12 students. Students involved in bullying were more susceptible to smoking, although patterns of association varied by grade level. In particular, the findings highlight that non-smoking middle school students involved in bullying were susceptible to future smoking. Copyright © 2016 Elsevier Inc. All rights reserved.

    Evidence suggests that smoking to cope among adolescents is associated with a number of problematic outcomes (e.g., greater smoking frequency, higher rates of dependence). It is thus imperative to better understand factors that may increase the likelihood of smoking to cope among adolescents. Research suggests anxiety sensitivity (AS) is associated with smoking to cope among adults, although the link between AS and coping motives for cigarette use among youth is less clear. Sex differences have also been noted in AS. The current study investigates this association using a biological challenge paradigm. Specifically, the indirect effects of anxious reactivity to bodily arousal on the relation between the physical and mental AS factors and coping motives for cigarette smoking were examined within a sample of 108 adolescent cigarette smokers. Sex was examined as a moderator. Results suggested significant indirect effects of self-reported anxiety in response to bodily arousal on the relation between physical AS and coping motives for cigarette smoking. This indirect effect was moderated by sex, such that it was significant for females but not males. Models examining AS mental concerns and psychophysiological responding to the challenge were not significant. These results suggest that, relative to their low-AS counterparts, female adolescents high in physical concerns respond with elevated anxiety in response to interoceptive arousal and, in turn, endorse elevated coping-related smoking motives. Findings are discussed in terms of implications for understanding the nature and origins of coping-related smoking motives and how such information can be utilized to inform intervention efforts.

    Higher rates of substance use and dependence have been observed in the offspring of mothers who smoked during pregnancy. Animal studies indicate that prenatal exposure to nicotine alters the development of brain areas related to reward processing, which might be a risk factor for substance use and addiction later in life. However, no study has examined the effect of maternal smoking on the offspring's brain response during reward processing. To determine whether adolescents with prenatal exposure to maternal cigarette smoking differ from their nonexposed peers in the response of the ventral striatum to the anticipation or the receipt of a reward. An observational case-control study. Data were obtained from the IMAGEN Study, a European multicenter study of impulsivity, reinforcement sensitivity, and emotional reactivity in adolescents. The IMAGEN sample consists of 2078 healthy adolescents (age range, 13-15 years) recruited from March 1, 2008, through December 31, 2011, in local schools. We assessed an IMAGEN subsample of 177 adolescents with prenatal exposure to maternal cigarette smoking and 177 nonexposed peers (age range, 13-15 years) matched by sex, maternal educational level, and imaging site. Response to reward in the ventral striatum measured with functional magnetic resonance imaging. In prenatally exposed adolescents, we observed a weaker response in the ventral striatum during reward anticipation (left side, F = 14.98 [P < .001]; right side, F = 15.95 [P < .001]) compared with their nonexposed peers. No differences were found regarding the responsivity of the ventral striatum to the receipt of a reward (left side, F = 0.21 [P = .65]; right side, F = 0.47 [P = .49]). The weaker responsivity of the ventral striatum to reward anticipation in prenatally exposed adolescents may represent a risk factor for substance use and development of addiction later in life. This result highlights the need for education and preventive

    Cognitive susceptibility to cigarette smoking has been demonstrated to predict future cigarette initiation in adolescents. Examining this construct prior to tobacco product initiation may provide useful information on the differential risk of individuals initiating cigarette vs. e-cigarette products. Additionally, examining how susceptibility and tobacco product use relate to perceived harm cognitions will increase understanding of risk predisposition among adolescents. Data were taken from a longitudinal study of middle school students (n = 1023; age = 12.1, 52.2% female, 72.1% white) in the Northeastern U.S. Likelihood of e-cigarette and cigarette ever-use in high school was examined as a function of a validated index of cigarette smoking susceptibility among tobacco naïve students in middle school. Prospective associations between cognitive susceptibility to smoking and subsequent perceived harm of e-cigarettes (assessed in high school), and cross-sectional associations between concurrent tobacco product ever-use status and perceived harm of e-cigarettes were examined. Adolescents classified as susceptible to cigarette smoking in middle school were more likely to initiate use of cigarettes (OR = 2.53) and e-cigarettes (OR = 1.95) as compared to adolescents classified as non-susceptible; cigarette smoking susceptibility did not differentially predict use of one product over the other. Adolescents endorsing e-cigarette use, reported significantly less perceived harm associated with e-cigarettes vs. cigarettes, while those who endorsed cigarette only or dual use did not. Our data indicate that cognitive susceptibility to cigarette smoking may index a broad risk factor for using either cigarettes or e-cigarettes in the future, and is prospectively associated with perceived harm of e-cigarette use. Overall, those who used any tobacco product perceived e-cigarettes as less harmful when compared to abstainers. Individual facets of perceived harm

    Background Peer and parental substance use are established predictors for substance use among adolescent, little is known about influence of sibling cigarette smoking and its interaction with peer network on substance use potential that can introduce an important way for substance use prevention programs. Objective The aim of present study was to explore the association of sibling cigarette smoking and peer network with substance use potential among high school students in Tehran. Subjects Data were drawn from the population-based cross-sectional study of among 650 high schools students. Methods Multiple linear regression was used in order to determine the adjusted association between cigarette smoking among family members, peer network, their interaction and substance use potential. Result Having a sister who smokes (B = 3.19; p < 0.01) and peer network quality were associated with substance use potential (B = -0.1; p < 0.05). The increase in mean of substance use potential associated with decreases in peer network quality score is much more than in who have a sister with a cigarette smoking habit. Conclusion Having a sister who smokes interacts with peer network quality; appears to be one of the important mechanisms for adolescents' tendency to substance use. These findings can help in a better understanding of substance use potential mechanisms, screening efforts and the formulation of prevention programs.

    BACKGROUND: Use of electronic cigarettes (e-cigarettes) among adolescents has increased since their introduction into the US market in 2007. Little is known about the role of e-cigarette psychosocial factors on risk of e-cigarette or cigarette use in adolescence. METHODS: Information on e-cigarette and cigarette psychosocial factors (use and attitudes about use in the home and among friends) was collected from 11th- and 12th-grade participants in the Southern California Children’s Health Study during the spring of 2014. RESULTS: Of 2084 participants, 499 (24.0%) had used an e-cigarette, including 200 (9.6%) current users (past 30 days); 390 participants (18.7%) had smoked a combustible cigarette, and 119 (5.7%) were current cigarette smokers. Cigarette and e-cigarette use were correlated. Nevertheless, 40.5% (n = 81) of current e-cigarette users had never smoked a cigarette. Psychosocial factors (home use of each product, friends’ use of and positive attitudes toward e-cigarettes and cigarettes) and participant perception of the harm of e-cigarettes were strongly positively associated both with e-cigarette and cigarette use. Most youth who reported e-cigarette use had friends who used e-cigarettes, and almost half of current users reported that they did not believe there were health risks associated with e-cigarette use. CONCLUSIONS: Longitudinal studies of adolescents are needed to determine whether the strong association of e-cigarette psychosocial factors with both e-cigarette and cigarette use will lead to increased cigarette use or dual use of cigarettes and e-cigarettes, or whether e-cigarettes will serve as a gateway to cigarette use.

    We examined whether externalizing problem behaviors (hyperactivity-impulsivity, aggressiveness, and inattention) predict illicit drug use independently, or whether their associations with drug use are mediated through cigarette smoking. We used a prospective longitudinal design within the FinnTwin12-17 study among Finnish adolescents with baseline at age 12 and follow-up surveys at ages 14 and 17. Path models were conducted with Mplus and included 1992 boys and 2123 girls. The outcome was self-reported ever use of cannabis or other illicit drugs at age 17. The predictors were: externalizing behaviors (hyperactivity-impulsivity, aggressiveness, and inattention) assessed by teachers and parents (age 12) and self-reported cigarette smoking (age 14). The findings differed across behavior studied. The association of hyperactivity-impulsivity with drug use was mostly mediated through earlier cigarette smoking. Concerning aggressiveness and inattention, the results were different among girls than boys. Among girls no significant mediation occurred, whereas among boys more consistent evidence on mediation was seen. Consistently in all models, the direct association of early cigarette smoking on drug use was strong and highly significant. We conclude that the associations of externalizing problem behaviors with illicit drug use are partially mediated through cigarette smoking. Although interventions targeting externalizing problem behaviors may protect adolescents from early onset smoking and subsequently experimenting with drugs, interventions to prevent cigarette smoking initiation are also important in reducing risk of later drug use.

    To examine risk factors associated with use of e-cigarettes only, conventional cigarettes only, and dual use in Korean adolescents and young adults. In a cross-sectional study, anonymous questionnaires were completed between April-May, 2015 among 1) 2744 middle and high school students, aged 13-18, from Seoul, Incheon, Gyeonggi, and Cheongju, Korea and 2) 2167 university students, aged 19-29, from fourteen universities in Korea. The results show that 12.6% of adolescents and 21.2% of university students reported having ever tried e-cigarettes at least once. Among the ever e-cigarette users, 95.1% and 96.3% of adolescents and university students also tried conventional cigarettes, respectively. Dual users were more likely to be male (adolescents: OR 2.63, 95% CI 1.93-3.57; university students: 4.28, 3.21-5.70), have any close friends who smoke (adolescents: 11.56, 7.63-17.53; university students: 11.29, 5.52-23.10), have any siblings who smoke (adolescents: 3.17, 2.25-4.46; university students: 1.78, 1.30-2.43), and have observed teachers smoke cigarettes at school (adolescents: 1.45, 1.05-2.01). A majority of e-cigarette users were dual users. Friends' and siblings' smoking status were significantly associated with dual product use in adolescent and young adult populations. Surveillance of e-cigarette use and implementation of evidence-based behavioral interventions targeting adolescents and young adults are necessary. Copyright © 2016 Elsevier Ireland Ltd.

    Subjective health complaints are common among adolescents. There is evidence that girls are more likely to register complaints than boys. This study examines gender differences in the relationship between daily smoking and recurrent subjective health complaints in school-aged adolescents in the USA. A cross-sectional design with a multistage probability sample was used to survey 13,339 middle and high school students (grades 6 through 10) with the US 2001-2002 Health Behavior in School-Aged Children Survey. Recurrent subjective health complaints were higher for adolescents who smoke daily and experiment with cigarettes than for those who never smoke. In logistic regression analyses, the odds of daily smoking increased twofold for both boys and girls who report recurrent irritability/bad temper. For girls, the odds of daily smoking were higher among those who reported recurrent headache, stomachache and backache compared with never smokers. For boys only recurrent backache and feeling dizzy were associated with increased odds of daily smoking. The relationship between recurrent subjective health complaints and daily smoking provides new insights into both conditions for school-aged adolescents. Findings from this study suggest different patterns of association between daily smoking and recurrent subjective health complaints occur for girls and boys. Further studies are needed to explore causes and treatment of daily smoking and recurrent health complaints among school-aged children. © 2010 Blackwell Publishing Ltd.

    Purpose This study examined the changes in friends’ and parental influences on cigarette smoking across two developmentally distinct social environments for adolescents: junior high school and high school. Methods Longitudinal data consisting of seven repeated measures following 1,001 adolescents from 7th to 12th grade was obtained from the Midwestern Prevention Project. A two-piece Growth Curve Model (GCM) was used to assess the growth trajectory of current cigarette use: one piece for the junior high school period, and the other for the high school period. Perceived friends’ and parental cigarette use were each used as a time-varying covariate in separate GCMs. Results Effects of friends’ and parental cigarette use remained significant on adolescent cigarette smoking across the two developmental periods. The magnitude of friends’ effect was in general higher during junior high school than high school. The magnitude of the parental effect remained relatively stable between the two periods. However, decreasing trends in both effects were observed from 10th to 12th grade. Gender differences also emerged. Friends’ and parental effects were greater for girls in their early high school years, whereas friends’ effect decreased in magnitude among girls and increased among boys during high school. Conclusions The transition from junior high school to high school represents an opportunity for interventions to counteract peer influence since such influence appeared to be much weaker during this period. However, interventions should continue to target parents as their behavior remains influential through the end of high school. PMID:23583505

    Despite anti-smoking prevention programs, many adolescents start smoking at school age. The main objectives of this study were to determine the prevalence and risk factors associated with smoking in adolescents living in Uruguaiana, RS, Brazil. A prospective study was conducted in adolescents (12-19 years), enrolled in municipal schools, who answered a self-administered questionnaire on smoking. 798 adolescents were enrolled in the study, with equal distribution between genders. The tobacco experimentation frequency (ever tried a cigarette, even one or two puffs) was 29.3%; 14.5% started smoking before 12 years of age and 13.0% reported smoking at least one cigarette/day last month. Having a smoking friend (OR: 5.67, 95% CI: 2.06-7.09), having cigarettes offered by friends (OR: 4.21, 95% CI: 2.46-5.76) and having easy access to cigarettes (OR: 3.82, 95% CI: 1.22-5.41) was identified as factors associated with smoking. Having parental guidance on smoking (OR: 0.67, 95% CI: 0.45-0.77), having no contact with cigarettes at home in the last week (OR: 0.51, 95% CI: 0.11-0.79) and knowing about the dangers of electronic cigarettes (OR: 0.88, 95% CI: 0.21-0.92) were identified as protection factors. The prevalence of smoking among adolescents in Uruguaiana is high. The implementation of measures to reduce/stop tobacco use and its new forms of consumption, such as electronic cigarettes and hookah, are urgent and imperative in schools.

    An inadequate diet and physical inactivity may compound the many deleterious effects of smoking on health. Some research indicates that smoking behavior is related to other health behaviors, but little research has examined how smoking may be related to dietary intake of key nutrients, consumption of fast food, sedentary lifestyle, or weight status. The purpose of this study was to describe smoking frequency among adolescents and its relationship to physical activity and dietary patterns. The research study employed a cross-sectional, population-based design. Adolescents self-reported cigarette smoking, physical activity, and eating behaviors on the Project EAT (Eating Among Teens) survey and reported dietary intake on a food frequency questionnaire completed in school classrooms. The sample included 4746 middle school and high school students from Minneapolis-St. Paul public schools. Mixed-model regression, which was controlled for sex, race and ethnicity, socioeconomic status, grade level (middle school or high school), and school, was used to examine the association of smoking with diet and physical activity patterns. Overall, reported smoking frequency was inversely related to participating in team sports, eating regular meals, and consuming healthful foods and nutrients. Smoking frequency was directly related to frequency of fast-food and soft drink consumption. Adolescents who smoke cigarettes may be less likely to engage in health-promoting lifestyle behaviors. Interventions are needed to prevent smoking and the unhealthy dietary practices and physical activity behaviors that may be associated with it.

    Research on adolescent cigarette smoking has attempted to measure the role of parents in preventing smoking experimentation and uptake. However, aspects of parental influence have often been limited to parental smoking behavior or antismoking socialization. Only a limited number of studies considered the hypothesis that the influence of parenting on adolescent current cigarette smoking may extend beyond parental behavior and antismoking socialization to consider broader measures of the parent-child relationship, such as parenting style. The sample was nationally representative and included 17,287 high school students nationwide. Data were used to categorize the parenting style--authoritative, permissive, autocratic, and unengaged--experienced by each respondent. Logistic regression analysis was used to assess the association between parenting style and adolescent current cigarette smoking. Authoritative parenting was associated with a reduction in the odds of adolescent current cigarette smoking (OR: 0.74, 99% CI: 0.58, 0.95). When authoritative parenting is simultaneously considered with believing parents' opinions about smoking are important, authoritative parenting was no longer a significant correlate of adolescent current cigarette smoking, while believing parents' opinions about smoking are important was associated with a 45% (99% CI: 0.48, 0.64) reduction in the odds of adolescent current cigarette smoking. Authoritative parenting was associated with a more than three-fold increase (OR: 3.65, 99% CI: 2.87, 4.66) in the odds of believing parents' opinions about smoking are important. Interventions may want to educate parents about authoritative parenting, which includes the importance of having appropriate and routine conversations with their children, requiring chores, and implementing general rules and boundaries.

    This study examined how factors associated with body image predict regular smoking in adolescent females. Data were from the National Longitudinal Study of Adolescent Health (Add Health), a study of health-related behaviors in a nationally representative sample of adolescents in grades 7 through 12. Females in Waves I and II (n=6,956) were used for this study. Using SUDAAN to adjust for the sampling frame, univariate and multivariate analyses were performed to investigate if baseline body image factors, including perceived weight, perceived physical development, trying to lose weight, and self-esteem, were predictive of regular smoking status 1 year later. In univariate analyses, perceived weight (p<.01), perceived physical development (p<.0001), trying to lose weight (p<.05), and self-esteem (p<.0001) significantly predicted regular smoking 1 year later. In the logistic regression model, perceived physical development (p<.05), and self-esteem (p<.001) significantly predicted regular smoking. The more developed a female reported being in comparison to other females her age, the more likely she was to be a regular smoker. Lower self-esteem was predictive of regular smoking. Perceived weight and trying to lose weight failed to reach statistical significance in the multivariate model. This current study highlights the importance of perceived physical development and self-esteem when predicting regular smoking in adolescent females. Efforts to promote positive self-esteem in young females may be an important strategy when creating interventions to reduce regular cigarette smoking. PMID:18686177

    IMPORTANCE Many adolescents and young adults use alternative tobacco products, such as water pipes and snus, instead of cigarettes. OBJECTIVE To assess whether prior water pipe tobacco smoking and snus use among never smokers are risk factors for subsequent cigarette smoking. DESIGN, SETTING, AND PARTICIPANTS We conducted a 2-wave national longitudinal study in the United States among 2541 individuals aged 15 to 23 years old. At baseline (October 25, 2010, through June 11, 2011), we ascertained whether respondents had smoked cigarettes, smoked water pipe tobacco, or used snus. At the 2-year follow-up (October 27, 2012, through March 31, 2013), we determined whether baseline non–cigarette smokers had subsequently tried cigarette smoking, were current (past 30 days) cigarette smokers, or were high-intensity cigarette smokers. We fit multivariable logistic regression models among baseline non–cigarette smokers to assess whether baseline water pipe tobacco smoking and baseline snus use were associated with subsequent cigarette smoking initiation and current cigarette smoking, accounting for established sociodemographic and behavioral risk factors. We fit similarly specified multivariable ordinal logistic regression models to assess whether baseline water pipe tobacco smoking and baseline snus use were associated with high-intensity cigarette smoking at follow-up. EXPOSURES Water pipe tobacco smoking and the use of snus at baseline. MAIN OUTCOMES AND MEASURES Among baseline non–cigarette smokers, cigarette smoking initiation, current (past 30 days) cigarette smoking at follow-up, and the intensity of cigarette smoking at follow-up. RESULTS Among 1596 respondents, 1048 had never smoked cigarettes at baseline, of whom 71 had smoked water pipe tobacco and 20 had used snus at baseline. At follow-up, accounting for behavioral and sociodemographic risk factors, baseline water pipe tobacco smoking and snus use were independently associated with cigarette smoking

The aim is knowing the relationship between cigarette smoking and practice of physical activity. Schooled Spanish adolescents 2859 Spanish adolescents (1357 boys, 1502 girls; age range: 13-18.5 years). A questionnaire is applied to know the level of cigarette smoking and four other questionnaires to know the level of physical activity during different periods. 40.8% of the adolescents stated not doing any physical activity at all, boys being more active than girls (p < 0.001). 29.9% of the adolescents stated usually smoking cigarettes, without differences by gender. Both active boys and girls stated smoking less (P < or = 0.01). The greater the age, the higher cigarette smoking and the lower the level of physical activity, both in boys and girls (p < 0.001). The level of physical activity is low, being even lower for girls. Cigarette smoking shows a negative relationship with the level of physical activity, the individuals more physically active being those smoking the less.

    Objective To evaluate developmental changes, personal smoking experiences, and vicarious smoking experiences as predictors of adolescents’ perceptions of the risks and benefits of cigarette smoking over time, in order to identify new and effective targets for youth smoking prevention programs. Design 395 adolescents were surveyed every six months for two school years, from the beginning of 9th grade to the end of 10th grade. Main Outcome Measures Time, participant smoking, friend smoking, parental smoking, and sex were evaluated as predictors of smoking-related short-term risk perceptions, long-term risk perceptions, and benefits perceptions using multilevel modeling techniques. Results Perceptions of benefits did not change over time. Perceptions of risk decreased with time, but not after sex and parental smoking were included in the model. Adolescents with personal smoking experience reported decreasing perceptions of risk and increasing perceptions of benefits over time. Adolescents with more than 6 friends who smoked also reported increasing perceptions of benefits over time. Conclusions Changes in risk perceptions may not purely be the result of developmental processes, but may also be influenced by personal and vicarious experience with smoking. Findings highlight the importance of identifying and targeting modifiable factors that may influence perceptions. PMID:20939640

    2014-01-01

    Introduction: This longitudinal study examined the association between trajectories of cigarette smoking and unemployment across a 29-year time period from mean age 14 to mean age 43. Methods: Participants came from a community-based random sample of residents in 2 upstate New York counties. Data were collected at 7 timepoints. Results: Using growth mixture modeling, 5 trajectory groups of cigarette smokers were identified. The trajectory groups were as follows: heavy/continuous smokers, occasional smokers, late-starting smokers, quitters/decreasers, and nonsmokers. Multivariate logistic regression analysis was used to study the relationship between the participant’s trajectory group membership and unemployment in the fifth decade of life. The association was determined with controls for age, gender, current cigarette use, current alcohol use, current marijuana use, physical diseases, occupation, educational level, past unemployment experience, socioeconomic status measures of family of origin, depressive mood, and self-control from adolescence through the early 40s. The findings indicate that patterns of adolescent and young adult cigarette smoking have implications for later unemployment. Overall, the results showed that people who fell into the categories of heavy/continuous smokers (adjusted odds ratio [AOR] = 3.84) and occasional smokers (AOR = 4.03) were more likely to be unemployed at mean age 43 when compared with nonsmokers. There was no significant difference between the quitters/decreasers and the nonsmokers with respect to unemployment. Conclusions: Intervention programs designed to deal with unemployment should consider focusing on heavy/continuous and occasional cigarette smokers as risk factors for unemployment. PMID:24997307

    Although adolescent cigarette use continues to decline in the United States, electronic cigarette (e‑cigarette) use among adolescents has escalated rapidly. This study assessed trends and patterns of e‑cigarette use and concurrent cigarette smoking and the relationships between e-cigarette use and smoking cessation intentions and behaviors among high school students in North Carolina. Data came from high school students who completed the school-based, cross-sectional North Carolina Youth Tobacco Survey in 2011 (n = 4,791) and 2013 (n = 4,092). This study assessed changes in prevalence of e-cigarette and cigarette use from 2011 through 2013, and cessation-related factors associated with those students' current and past use of e‑cigarettes in 2013. The prevalence of current e-cigarette use (use in the past 30 days) significantly increased from 1.7% (95% CI, 1.3%-2.2%) in 2011 to 7.7% (95% CI, 5.9%-10.0%) in 2013. Among dual users, current e-cigarette use was negatively associated with intention to quit cigarette smoking for good (relative risk ratio [RRR] = 0.51; 95% CI, 0.29-0.87) and with attempts to quit cigarette smoking in the past 12 months (RRR = 0.69; 95% CI, 0.49-0.97). Current e-cigarette smokers were less likely than those who only smoked cigarettes to have ever abstained from cigarette smoking for 6 months (RRR = 0.42; 95% CI, 0.21-0.82) or 1 year (RRR = 0.21; 95% CI, 0.09-0.51) and to have used any kind of aids for smoking cessation (RRR = 0.46; 95% CI, 0.29-0.74). Public health practitioners and cessation clinic service providers should educate adolescents about the risks of using any nicotine-containing products, including e-cigarettes, and provide adequate tobacco cessation resources and counseling to adolescent tobacco users.

    To examine the relationship between exposure to pro-smoking messages in media and susceptibility to smoking adoption among middle school students. The hypothesis that parental restriction of R-rated movie viewing is associated with lower adolescent smoking susceptibility was tested. A sample of 1687 6th-, 7th-, and 8th-grade students from four Wisconsin middle schools were surveyed about their use of cigarettes, exposure to smoking in media, their views of smoking, and peer smoking behaviors. An index of smoking susceptibility was created using measures of cigarette use and future intention to smoke. A zero-order correlation for parental restriction of R-rated movie viewing and smoking susceptibility showed a strong association (r = -.36, p < .001). A hierarchical logistic regression yielded odds ratios (ORs) for being susceptible to or having tried smoking for three levels of parental R-rated movie restriction. Results show that compared to full restriction, respondents with partial or no restriction were more likely to be susceptible to smoking (partial restriction: OR = 2.1, 95% CI = 1.5-2.8; no restriction: OR = 3.3, 95% CI = 2.3-4.6), when controlling for demographic factors, and family and friend smoking. Analyses using a measure of smoking prevalence as the dependent variable yielded similar results (partial restriction: OR = 1.5, 95% CI = 1.0-2.2; no restriction: OR = 2.5, 95% CI = 1.7-3.7). Parental restriction of R-rated movie viewing is associated with both lower adolescent smoking susceptibility and lower smoking rates.

    Adolescent tobacco use remains a major public health priority to reduce the prevalence of tobacco use in community. The aim of this study was determining the association of the transitions in smoking stages with prevalence of cigarette smoking in the classes and schools in adolescents of Tabriz City (northwest of Iran). Fifty-six high schools were randomly selected, and 4903 students completed a self-administered questionnaire on cigarette smoking twice with a 12-months interval in 2010 and 2011. Transition from experimenter to regular smoker stage was associated with the prevalence of cigarette smoking in the school. The results have shown the association of student's smoking uptake with the prevalence of cigarette smoking in the school. This highlights the importance of enforcing smoke free policies in schools.

    To examine the sociodemographic traits of adolescent e-cigarette users and whether e-cigarettes are used as cessation aids among adolescent smokers. The study had a cross-sectional design. Study setting was the United States. A probability sample of 15,264 adolescents in grades 6 through 12 was used. The study measured self-reported lifetime e-cigarette use and recent conventional cigarette use, desire to quit, and number of recent quit attempts (among conventional cigarette smokers), and factors hypothesized to be related to e-cigarette use (e.g., race/ethnicity, age, friendships with smokers). Logistic regression was used to assess e-cigarette use among (1) all adolescents and (2) conventional cigarette smokers as a function of quit desire and attempts. Descriptive analyses show 3.2% of respondents had used e-cigarettes. E-cigarette use is significantly lower for females (adjusted odds ratio [OR], .70), non-Hispanic black youth (adjusted OR, .37), and Mexican-American youth (adjusted OR, .56), and higher for those who smoke conventional cigarettes (adjusted OR, 58.44) or have friends who smoke (adjusted OR, 2.38). Among conventional cigarette smokers, neither desire to quit nor recent quit attempts is significantly associated with e-cigarette use. E-cigarette use is more common among certain adolescent subgroups than others and does not appear to be part of a cessation regimen among conventional cigarette smokers wishing to quit. More regulatory and prevention efforts are needed, especially for certain adolescent subpopulations.

    Little evidence regarding longitudinal predictors of cigarette smoking progression is available from developing countries. This study aimed to identify gender-specific individual and social predictors of cigarette smoking progression among a school-based sample of adolescents in Irbid, Jordan. A total of 1781 seventh graders (participation rate 95%) were enrolled and completed an annual self-administered questionnaire from 2008 through 2011. Students who reported "ever-smoking a cigarette" at baseline or in the subsequent follow-up but not being "heavy daily smokers" (>10 cigarettes per day) were eligible for this analysis (N = 669). Grouped-time survival analyses were used to identify predictors of cigarette smoking progression in boys and girls. Among the study sample, 38.3% of students increased the frequency and /or amount of cigarette smoking during the 3 years of follow-up. Among individual factors, the urge to smoke in the morning predicted smoking progression for boys and girls. The independent predictors of cigarette smoking progression were friends' smoking and attending public schools in boys, and siblings' smoking in girls. Discussing the dangers of smoking with family members was protective for girls. Boys and girls progressed similarly in cigarette smoking once they initiated the habit. Progression among girls was solely family-related, while it was peer-related for boys. © The Author 2015.

    OBJECTIVE: The aim of this study was to analyze social characteristics and stress as correlates of cigarette smoking in adolescence. The main intent was to identify elements that distinguish adolescents who had experimented with smoking and did not progress to regular smoking from those who became current smokers. METHODS: Students at 10 high schools in the city of Ribeirão Preto, Brazil, completed a questionnaire based on an instrument employed in a similar large-scale study. The students were classified as never-smokers or experimenters. The experimenters were subcategorized as having become current smokers or nonprogressors. Analyses were performed using adjusted logistic models. RESULTS: A total of 2,014 students (mean age, 16.2 ± 1.1 years; females, 53%) completed the questionnaire. We categorized 1,283 students (63.7%) as never-smokers, 244 (12.1%) as current smokers, and 487 (24.2%) as nonprogressors. We found that experimentation with smoking was associated with being held back a grade in school (OR = 1.80), alcohol intake (low/occasional, OR = 8.92; high/regular, OR = 2.64), illicit drug use (OR = 9.32), having a sibling or cousin who smokes (OR = 1.39), having a friend who smokes (OR = 2.08), and high levels of stress (in females only, OR = 1.32). Factors associated with an increased risk of transitioning from experimenter to current smoker were alcohol intake (low/occasional, OR = 3.28; high/regular, OR = 2.16), illicit drug use (OR = 3.61), and having a friend who smokes (OR = 7.20). CONCLUSIONS: Current smoking was associated with a profile of socioeconomic correlates different from that associated with experimentation only. Our data (showing that current smoking was associated with having a friend who smokes, alcohol intake, and illicit drug use) suggest the need for comprehensive approaches to discourage substance use during adolescence.

    Background Parental smoking and early-emerging nicotine dependence symptoms are well-documented risk factors for adolescent smoking. However, very little is known about the mediating pathways through which these risk factors may act, or whether parental smoking may cause or signal early-emerging nicotine dependence symptoms. Methods Data were drawn from the longitudinal Social and Emotional Contexts of Adolescent Smoking Patterns Study. Adolescents who had smoked under 100 cigarettes in their lifetime (n=594; low-exposure group) and adolescents who had smoked over 100 cigarettes, but fewer than 5 cigarettes per day (n=152) were included in the analyses. Path analysis was performed on longitudinal data to investigate the association between parental smoking and smoking frequency at the 48 month follow-up, both directly and through mediating variables of smoking frequency, smoking quantity, and nicotine dependence. Results Father’s smoking was associated with higher adolescent nicotine dependence scores at the baseline assessment wave. Structural equation modeling revealed that mother’s smoking at baseline was associated with adolescent’s smoking frequency at the 48 month follow-up, and its effect was partially mediated by both smoking frequency and nicotine dependence among low-exposure adolescent smokers. Conclusions Parental smoking is a risk factor for future smoking in low-exposure adolescent smokers, above and beyond the risks posed by smoking behavior and nicotine dependence. Moreover, parental smoking is associated with early-onset nicotine dependence in low-exposure adolescent smokers. As an easily measureable risk factor, parent smoking status can be used to identify and intervene with novice adolescent smokers who are at high risk for chronic smoking behavior. PMID:22365898

    OBJECTIVES To measure community-level changes in the methods youth use to obtain cigarettes over time and to relate these methods to the progression of smoking. METHODS We analyzed 2000-2003 data from the Minnesota Adolescent Community Cohort study, where youth (beginning at age 12), who were living in Minnesota at baseline, were surveyed every six months via telephone. We conducted mixed model repeated measures logistic regression to obtain probabilities of cigarette access methods among past 30-day smokers (n = 340 at baseline). RESULTS The probability of obtaining cigarettes from a commercial source in the past month declined from 0.36 at baseline to 0.22 at the sixth survey point while the probability of obtaining cigarettes from a social source during the previous month increased from 0.54 to 0.76 (p for both trends = 0.0001). At the community level, the likelihood of adolescents obtaining cigarettes from social sources was inversely related to the likelihood of progressing to heavy smoking (p < 0.001). CONCLUSIONS During this time, youth shifted to greater reliance on social sources and less on commercial sources. A trend toward less commercial access to cigarettes accompanied by an increase in social access may translate to youth being less likely to progress to heavier smoking. PMID:17719080

    Cigarette smoking is a major preventable cause of serious chronic disease. The majority of smokers begin smoking during their adolescent years. Print cigarette advertising plays an influential role in encouraging young people to smoke. Eight hundred and forty-three middle/junior high-school-aged students from a large midwestern metropolitan area participated in this study of adolescents' recognition of and belief in messages associated with print cigarette advertising. Results indicated no significant difference between smokers and nonsmokers in their recognition of messages associated with print cigarette advertising. However, smokers and nonsmokers differed significantly in the degree to which they believed the messages communicated by print cigarette advertising. Consistent with social cognitive theory, students who smoke at least occasionally were more likely to believe messages conveyed by print cigarette ads than were students who had never smoked. Implications of these findings for research and practice are discussed, including specification of guidelines for effective counteradvertising.

    Symptoms adolescents experience during their first time using a cigarette predict their current use, but little is known regarding the symptoms experienced during first e-cigarette use. We conducted a pilot study to understand the symptoms adolescents experience when they first tried cigarettes and e-cigarettes and the associations between these symptoms and current use. Participants were 41 adolescents in two U.S. cities who had tried cigarettes or e-cigarettes. We asked adolescents to recall the symptoms they experienced during their first cigarette or e-cigarette and categorized symptoms as negative (felt bad, coughing/chest pain, bad taste, upset stomach, dizzy/lightheaded) or positive (felt relaxed, rush/buzz). Adolescents reported fewer negative symptoms for first e-cigarette than first cigarette use (all p < 0.05). Current cigarette smoking was associated with endorsing fewer negative symptoms (OR = 0.49, 95% CI = [0.25, 0.95]) and more positive symptoms (OR = 7.11, 95% CI = [1.47, 34.33]) at first cigarette use. First e-cigarette use symptoms were not associated with current e-cigarette use. Adolescents reported fewer negative symptoms from first e-cigarette than from first cigarette, and e-cigarette symptoms did not influence use as they do for cigarettes. Additional research is needed to confirm these findings in longitudinal studies.

    Introduction The Tobacco Control Act requires public disclosure of information about toxic constituents in cigarette smoke. To inform these efforts, we studied public understanding of cigarette smoke constituents. Methods We conducted phone surveys with national probability samples of adolescents (n=1125) and adults (n=5014) and an internet survey with a convenience sample of adults (n=4137), all in the USA. We assessed understanding of cigarette smoke constituents in general and of 24 specific constituents. Results Respondents commonly and incorrectly believed that harmful chemicals in cigarette smoke mostly originate in additives introduced by cigarette manufacturers (43–72%). Almost all participants had heard that nicotine is in cigarette smoke, and many had also heard about carbon monoxide, ammonia, arsenic and formaldehyde. Less than one-quarter had heard of most other listed constituents being in cigarette smoke. Constituents most likely to discourage respondents from wanting to smoke were ammonia, arsenic, formaldehyde, hydrogen cyanide, lead and uranium. Respondents more often reported being discouraged by constituents that they had heard are in cigarette smoke (all p<0.05). Constituents with names that started with a number or ended in ‘ene’ or ‘ine’ were less likely to discourage people from wanting to smoke (all p<0.05). Discussion Many people were unaware that burning the cigarette is the primary source of toxic constituents in cigarette smoke. Constituents that may most discourage cigarette smoking have familiar names, like arsenic and formaldehyde and do not start with a number or end in ene/ine. Our findings may help campaign designers develop constituent messages that discourage smoking. PMID:27924009

    Accumulating evidence suggests that widespread advertising for cigarettes at the point of sale encourages adolescents to smoke; however, no longitudinal study of exposure to retail tobacco advertising and smoking behavior has been reported. A school-based survey included 1681 adolescents (aged 11-14 years) who had never smoked. One measure of exposure assessed the frequency of visiting types of stores that contain the most cigarette advertising. A more detailed measure combined data about visiting stores near school with observations of cigarette advertisements and pack displays in those stores. Follow-up surveys 12 and 30 months after baseline (retention rate: 81%) documented the transition from never to ever smoking, even just a puff. After 12 months, 18% of adolescents initiated smoking, but the incidence was 29% among students who visited convenience, liquor, or small grocery stores at least twice per week and 9% among those who reported the lowest visit frequency (less than twice per month). Adjusting for multiple risk factors, the odds of initiation remained significantly higher (odds ratio: 1.64 [95% confidence interval: 1.06-2.55]) for adolescents who reported moderate visit frequency (0.5-1.9 visits per week), and the odds of initiation more than doubled for those who visited > or = 2 times per week (odds ratio: 2.58 [95% confidence interval: 1.68-3.97]). Similar associations were observed for the more detailed exposure measure and persisted at 30 months. Exposure to retail cigarette advertising is a risk factor for smoking initiation. Policies and parenting practices that limit adolescents' exposure to retail cigarette advertising could improve smoking prevention efforts.

    This study uses the most recent data from the nationally representative National Youth Tobacco Survey (NYTS) to examine the use of alternative tobacco products among U.S. cigarette smokers and non-cigarette smokers aged 14-17. Alternative tobacco product use is defined as use of one or more of the following products: smokeless tobacco, cigars, pipes, bidis, or kreteks. Using the results from the 2004, 2006, and 2009 NYTS, multivariate logistic regressions were used to investigate separately the extent of alternative tobacco product use in current cigarette smokers and in those who reported not smoking cigarettes controlling for demographic and other independent influences. The results indicate that for adolescent smokers and nonsmokers, the use of one type of alternative tobacco product made it much more likely the individual would use one or more of the other alternative tobacco products. Non-cigarette smokers using these tobacco products appeared to exhibit symptoms of nicotine dependence comparable to those of cigarette smokers. More information on adolescent use of alternative tobacco products is needed. Current cigarette use declined 3.4% annually over 2004-2009 for the NYTS 14- to 17-year-old population, but this cohort's use of alternative tobacco products was unchanged. The number of adolescents aged 14-17 who did not smoke cigarettes but used alternative tobacco products increased 5.9% per year over the same period. Current surveillance measures need to be expanded in order to gain a more comprehensive understanding of adolescent alternative tobacco use.

    ABSTRACT Background: The prevalence of adolescent tobacco use in Indonesia is among the highest in the world. Monitoring the extent and distribution of adolescent cigarette smoking is crucial to being able to target prevention and reduction strategies and evaluate the effectiveness of interventions. Objectives: To quantify the prevalence of adolescent cigarette smoking in Indonesia and assess the association with key socio-economic, demographic and geographic factors. Methods: We used data from the 2013 Indonesian Basic Health Research (RISKESDAS) national household survey to quantify the prevalence of cigarette smoking in adolescents aged 10–18 years by sex, age, education, economic status, place of residence and province. We used logistic regression to assess the adjusted association between adolescent smoking and these factors. Results: The overall smoking prevalence among Indonesian  adolescents was 7.2% (95% Confidence Interval/CI: 7.1–7.4). The prevalence was substantially higher among males (14.0%; 95% CI: 13.6–14.4) compared with females (0.2%; 95% CI: 0.1–0.4). After controlling for socio-economic, demographic and geographic characteristics, higher odds of smoking were observed among males (OR = 118.1; 95% CI: 91.2–153.0) as compared to female and among  adolescents aged 13–15 and 16–18 years as compared to those aged 10–12 years (OR = 13.2; 95% CI: 10.8–16.2 and OR = 72.7; 95% CI: 59.1–89.4, respectively). The odds of smoking were greater among adolescents with higher education as compared to those with lower education (OR = 1.3; 95% CI: 1.1–1.4) and adolescents in the poorest quintile had more than twice the odds of smoking compared with adolescents from the richest quintile (OR = 2.5; 95% CI: 2.2–2.8). Conclusion: Smoking prevention and cessation interventions in Indonesia need to be specific considering the sex, age, socioeconomic status and geographic location of adolescents.

    Introduction Although adolescent cigarette use continues to decline in the United States, electronic cigarette (e‑cigarette) use among adolescents has escalated rapidly. This study assessed trends and patterns of e‑cigarette use and concurrent cigarette smoking and the relationships between e-cigarette use and smoking cessation intentions and behaviors among high school students in North Carolina. Methods Data came from high school students who completed the school-based, cross-sectional North Carolina Youth Tobacco Survey in 2011 (n = 4,791) and 2013 (n = 4,092). This study assessed changes in prevalence of e-cigarette and cigarette use from 2011 through 2013, and cessation-related factors associated with those students’ current and past use of e‑cigarettes in 2013. Results The prevalence of current e-cigarette use (use in the past 30 days) significantly increased from 1.7% (95% CI, 1.3%–2.2%) in 2011 to 7.7% (95% CI, 5.9%–10.0%) in 2013. Among dual users, current e-cigarette use was negatively associated with intention to quit cigarette smoking for good (relative risk ratio [RRR] = 0.51; 95% CI, 0.29–0.87) and with attempts to quit cigarette smoking in the past 12 months (RRR = 0.69; 95% CI, 0.49–0.97). Current e-cigarette smokers were less likely than those who only smoked cigarettes to have ever abstained from cigarette smoking for 6 months (RRR = 0.42; 95% CI, 0.21–0.82) or 1 year (RRR = 0.21; 95% CI, 0.09–0.51) and to have used any kind of aids for smoking cessation (RRR = 0.46; 95% CI, 0.29–0.74). Conclusion Public health practitioners and cessation clinic service providers should educate adolescents about the risks of using any nicotine-containing products, including e-cigarettes, and provide adequate tobacco cessation resources and counseling to adolescent tobacco users.

    The socio-cultural environment is an important factor involved with the onset of smoking during adolescence. Initiation of cigarette smoking occurs almost exclusively during this stage. In this context we aimed to analyze the association of school and family factors with adolescent smoking by a cross-sectional study of 16 secondary schools randomly selected from the Balearic Islands involved 3673 students and 530 teachers. The prevalence of regular smoking (at least one cigarette per week) was 4.8% among first year students, 11.6% among second year students, 14.1% among third year students, 20.9% among fourth year students and 22% among teachers. Among first and second year students, there were independent associations between regular smoking and adolescents' perception of being allowed to smoke at home, belonging to a single parent family, poor relationship with parents, poor academic performance, lack of interest in studies and teachers' perception of smoking in the presence of pupils. Among third and fourth year students, there were independent associations between regular smoking and poor relationship with parents, adolescents' perception of being allowed to smoke at home, poor academic performance, lack of control over student misbehavior and the school attended. The school policies and practices affect student related health behavior regarding smoking, independent of individual and family factors.

  17. Peer beliefs and smoking in adolescence: a longitudinal social network analysis.

    2016-03-01

    Peer smoking is one of the strongest predictors of adolescent cigarette use, but less is known about whether other peer characteristics also contribute to this behavior. This study examined the links between adolescent cigarette use and peer beliefs about smoking. It tested whether peer beliefs about smoking are associated with changes in cigarette use, whether this association is a result of changes in individual beliefs about smoking, and how beliefs inform friendship choices. Analyses drew on data collected from 29 school-based networks, each measured at five occasions as students moved from 6th through 9th grade, as part of the study of the PROSPER partnership model. Longitudinal social network models provided estimates of friendship selection and behavior for an average of 6,200 students at each measurement point and more than 9,000 students overall. Peer beliefs about smoking influenced cigarette use both directly and through their impact on individual beliefs. Respondents tended to name friends whose beliefs about smoking were similar to their own, and the likelihood of being named as a friend was higher for those who reported more positive beliefs about smoking. The results from this study suggest that peer beliefs about smoking, in addition to peer cigarette use itself, are associated with adolescent smoking through several mechanisms. Because beliefs favorable to cigarette use are present before adolescents actually smoke, these results underscore the importance of implementing smoking prevention programs in early adolescence.

    We report the results of a study examining the level of advertisement recognition and tobacco experimentation in a group of U.S. high school students. Students who smoked as few as one cigarette per week were found to identify a preferred cigarette brand. One brand of cigarettes accounted for 76% of all preferred brands. A dose-response relationship was found between smoking level and cigarette advertisement recognition, with regular smokers recognizing 61.6% of advertisements, compared with only 33.2% for nonsmokers. These data have potential implications for youth smoking prevention programs. Future research is needed to explain this association and to establish whether cigarette advertising and adolescent smoking are causally related.

    Graphic warning labels and plain cigarette packaging are two initiatives developed to increase quit behaviour among smokers. Although a little is known about how adolescents interpret graphic warning labels, very few studies have examined how plain cigarette packaging would affect adolescents' perceptions of cigarette smoking and smoking behaviour. We explored how teens interpret and respond to graphic warning labels and the plain packaging of cigarettes, to assess the potential these strategies may offer in deterring smoking initiation. Twelve focus group interviews with a sample of 80 14-16 year old students from a diverse range of schools in Auckland, New Zealand were undertaken between June and August 2009. Textual analysis revealed that graphic warning labels may influence adolescents by reiterating a negative image of smokers. Graphic warning on a plain cigarette pack increased the attention paid to graphic warning labels and the overall perceptions of harm caused by cigarette smoking, and reduced the social appeal of cigarette smoking. This research offers evidence on how adolescents are appraising and interpreting graphic warning labels, and explores how dominant appraisals may affect the role graphic warning labels play in preventing smoking. Not only would plain cigarette packaging enhance the salience and impact of graphic warning labels, but it would potentially bolster the overall message that cigarette smoking is harmful. In the context of a comprehensive tobacco control programme, graphic warning labels on plain cigarette packaging present an explicit message about the risks (to health and image) associated with cigarette smoking.

    The risk of tobacco use during adolescence may be traced back to early childhood, the time when a child is most vulnerable to environmental influence. We examined daily-life enrichment during pre-kindergarten period as a predictor of initiation of cigarette smoking among Asian American and Hispanic/Latino children during adolescence. Survey data…

    Despite the potential negative health effects of electronic cigarettes (e-cigarettes), these devices are increasing in popularity worldwide, especially among youth. We compared data from two cross-sectional studies conducted in Poland among students aged 15-19 years in 2010-2011 and 2013-2014. We tested differences between samples in the prevalence of e-cigarette use, tobacco cigarette smoking, and simultaneous use of both tobacco and e-cigarettes ("dual use") using a multilevel linear mixed model regression. We found that the current use of e-cigarettes among adolescents in Poland was significantly higher in the 2013-2014 sample than the 2010-2011 sample (29.9% vs. 5.5%, respectively; p < .05). Dual use of tobacco and e-cigarettes was also significantly higher (21.8% vs. 3.6%, respectively; p < .05). Interestingly, the prevalence of smoking tobacco cigarettes also increased (from 23.9% in 2010-2011 to 38.0% in 2013-2014; p < .05). Observed parallel increase in e-cigarette use and smoking prevalence does not support the idea that e-cigarettes are displacing tobacco cigarettes in this population.

    Exposure to cigarette coupons is associated with smoking initiation and likelihood of cigarette purchase among adolescents. Some adolescents who are exposed to cigarette coupons take a step further by choosing to save or collect these coupons, a further risk factor for cigarette smoking. This study examines historical trends and disparities in cigarette coupon saving among adolescents in the United States from 1997 to 2013. National samples of 10th and 12th grade students (n=129,111) were obtained from Monitoring the Future surveys in 1997-2013. Prevalence of lifetime and current cigarette coupon saving was estimated in each year in the overall adolescent population, and in race/ethnicity, parent education level, sex, and urban/rural subgroups. Prevalence of lifetime and current cigarette coupon saving was then estimated in each year based on smoking status. Prevalence of cigarette coupon saving has decreased dramatically among adolescents; only 1.2% reported currently saving coupons in 2013. However, disparities in cigarette coupon saving remain with prevalence higher among rural, White, and low parental education level students. Adolescent smokers continue to save coupons at high rates; 21.2% had ever saved coupons and 6.9% currently saved coupons as of 2013. Despite overall declines in adolescent cigarette coupon saving, existing sociodemographic disparities and the considerably high prevalence of coupon saving among adolescent smokers suggest that cigarette coupons remain a threat to smoking prevention among youth. Additional research is needed to further elucidate longitudinal associations between cigarette coupon saving and smoking initiation and maintenance among adolescents. Copyright © 2017 Elsevier Inc.

    2004-10-01

    Cigarette advertising may be partly responsible for adolescent smoking initiation, but few studies have investigated the advertising and individual difference factors that may be responsible. This study evaluated whether individual differences in the number of self-conflicts (i.e., conflicts between personality attributes experienced as part of self-concept development) interacts with stage of development (early versus middle adolescence) to predict responses to cigarette advertising imagery. One hundred and one never smoking adolescents judged the self-relevance of various cigarette advertisements. As predicted, self-conflict was related to judgments of self-relevance for early adolescents only; early adolescents who are having the most difficulty defining themselves are more likely to look to the powerful images displayed by cigarette advertisements for help. These results have implications for understanding the impact of cigarette advertising on smoking initiation for some adolescents.

    2011-01-01

    OBJECTIVES Accumulating evidence suggests that widespread advertising for cigarettes at the point of sale encourages adolescents to smoke; however, no longitudinal study of exposure to retail tobacco advertising and smoking behavior has been reported. METHODS A school-based survey included 1681 adolescents (aged 11–14 years) who had never smoked. One measure of exposure assessed the frequency of visiting types of stores that contain the most cigarette advertising. A more detailed measure combined data about visiting stores near school with observations of cigarette advertisements and pack displays in those stores. Follow-up surveys 12 and 30 months after baseline (retention rate: 81%) documented the transition from never to ever smoking, even just a puff. RESULTS After 12 months, 18% of adolescents initiated smoking, but the incidence was 29% among students who visited convenience, liquor, or small grocery stores at least twice per week and 9% among those who reported the lowest visit frequency (less than twice per month). Adjusting for multiple risk factors, the odds of initiation remained significantly higher (odds ratio: 1.64 [95% confidence interval: 1.06–2.55]) for adolescents who reported moderate visit frequency (0.5–1.9 visits per week), and the odds of initiation more than doubled for those who visited ≥2 times per week (odds ratio: 2.58 [95% confidence interval: 1.68–3.97]). Similar associations were observed for the more detailed exposure measure and persisted at 30 months. CONCLUSIONS Exposure to retail cigarette advertising is a risk factor for smoking initiation. Policies and parenting practices that limit adolescents’ exposure to retail cigarette advertising could improve smoking prevention efforts. PMID:20643725

    Pictorial cigarette pack warnings are a promising policy solution to increase smoking cessation among adults. However, little is known regarding adolescents' responses to pictorial warnings, particularly in real-world settings. Participants were 112 adolescent children, ages 13-17, whose parents received either text-only warnings on the side of their cigarette packs or pictorial warnings on the top half of the front and back of their cigarette packs for 4 weeks as part of a trial. We measured adolescents' recall and recognition of these warnings, negative emotional reactions to the warnings, perceived effectiveness of the warnings, social interactions about the warnings, and smoking risk beliefs. Adolescents accurately recalled pictorial warnings more often than text-only warnings (82% vs. 19%, p < .001). Recognition of warnings was also higher for pictorial than text-only warnings (82% vs. 34%, p < .001). Pictorial warnings drew greater attention (p < .001), elicited greater negative emotional reactions (p < .05), and sparked more social interactions (p < .01) than text-only warnings. Pictorial warnings on cigarette packs may have important effects on adolescent children of smokers. Future research should further investigate the impact of such messages on adolescents' susceptibility to smoking initiation and interest in quitting smoking, particularly as the United States and other countries work to implement pictorial warning regulations.

    Introduction: Research has shown that adults perceive that electronic cigarettes (e-cigarettes) are effective for smoking cessation, yet little is known about adolescents and young adults’ perceptions of e-cigarettes for quitting cigarette smoking. This study describes middle, high school, and college students’ beliefs about, and experiences with, e-cigarettes for cigarette smoking cessation. Methods: We conducted 18 focus groups (n = 127) with male and female cigarette smokers and nonsmokers in 2 public colleges, 2 high schools, and 1 middle school in Connecticut between November 2012 and April 2013. Participants discussed cigarette smoking cessation in relation to e-cigarettes. Verbatim transcripts were analyzed using thematic analysis. Results: All participants, regardless of age and smoking status, were aware that e-cigarettes could be used for smoking cessation. College and high school participants described different methods of how e-cigarettes could be used for smoking cessation: (a) nicotine reduction followed by cessation; (b) cigarette reduction/dual use; and (c) long-term exclusive e-cigarette use. However, overall, participants did not perceive that e-cigarette use led to successful quitting experiences. Participants described positive attributes (maintenance of smoking actions, “healthier” alternative to cigarettes, and parental approval) and negative attributes (persistence of craving, maintenance of addiction) of e-cigarettes for cessation. Some college students expressed distrust of marketing of e-cigarettes for smoking cessation. Conclusions: Adolescent and young adult smokers and nonsmokers perceive that there are several methods of using e-cigarettes for quitting and are aware of both positive and negative aspects of the product. Future research is needed to determine the role of e-cigarettes for smoking cessation in this population. PMID:25646346

    Use of electronic cigarettes (e-cigarettes) among adults has flourished in recent years. However, little is known about their use among adolescents. This article reports on data collected from a New Zealand national youth tobacco use survey in 2012 and 2014. The Youth Insights Survey is a biennial self-complete survey of Year 10 students (predominately aged 14-15 years), with a sample size of 3,127 in 2012 and 2,919 in 2014. Ever-use of e-cigarettes was self-reported by participants in both years, and in 2014, e-cigarette ever-users also reported their reasons for first trying e-cigarettes. The rate of e-cigarette ever-use tripled from 7.0% in 2012 to 20.0% in 2014. After adjusting for sociodemographic variables, smoking status (including susceptibility), and other factors associated with tobacco smoking uptake, e-cigarette ever-use was associated with gender, smoking status, close friends' smoking behavior, and risky substance use. Among smokers, desire for a cigarette, quit intention, or past-year quit attempts did not predict e-cigarette ever-use. Irrespective of smoking status, curiosity was the most commonly cited reason for trying e-cigarettes. In 2014, one in five 14- to 15-year-olds had used e-cigarettes. Our data suggest that for adolescent smokers, cessation was not the main reason for trying e-cigarettes. Instead, most adolescents (smokers and nonsmokers) tried e-cigarettes out of curiosity. Our findings signal a need to continue monitoring the uptake of e-cigarettes among adolescents, including both experimental and long-term use. Controlling access and exposure to e-cigarettes among this young age group is also required. Copyright © 2015 Society for Adolescent Health and Medicine. Published by Elsevier Inc.

    Smoking continues to be a leading cause of preventable deaths and rates of trying cigarettes and progression to daily smoking among adolescents continues to remain high. A plethora of risk factors for smoking among adolescents has been addressed in the research literature. One that is gaining particular interest is the relationship between adolescent mental health and smoking (both initiation and progression). This paper reviews the evidence for adolescent mental health as a risk factor for cigarette smoking. We focus on the specific mental health conditions that have been more thoroughly addressed as possible risk factors in community-dwelling adolescents. We discuss the multiple hypotheses that have been posited as to the nature of the relationship between adolescent mental health and smoking, as well as detailing so called third factors that may account for the observed relationship. We highlight the contribution of the existing studies to the body of knowledge on this topic, as well as the limitations and open questions that remain as a result. We conclude with discussion of a broad research agenda going forward. PMID:24600273

    Background Cigarette smoking behavior is highly determined by social influences during childhood and adolescence. This phenomenon has not been fully evaluated in the Hispanic/Latino population. Purpose To examine the association between exposure to household cigarette smoking behavior (HCSB) with adult cigarette smoking among a diverse Hispanic/Latino population living in four US urban centers. The effect of acculturation on cigarette smoking was also evaluated. Methods Data from the Hispanic Community Health Study/Study of Latinos (HCHS/SOL) (n=13,231, ages 18–74 years, collected between March 2008 and June 2011) were analyzed using logistic regression. Results HCSB exposure was an independent risk factor for adult current cigarette smoking in Hispanic/Latinos (OR 1.7; 95% CI 1.4, 2.1) after controlling for relevant confounders including socio-demographic and cultural factors. Cubans and Puerto Ricans had the highest prevalence of HCSB exposure (59% and 47% respectively) and highest prevalence of current cigarette smoking (26% and 32%) compared with other Hispanic/Latino groups, (p <.01). Conclusions Our data suggest that exposure to HCSB in Hispanics/Latinos living in the US is an independent predictor of adult cigarette smoking, and this association appears to be strongest in Cubans and Puerto Ricans.

    A survey of a secondary school serving a small town and rural district in New Zealand revealed that 46 percent of the students, aged 12 to 18, were current cigarette smokers. The smoking habits of elder siblings and peers were closely related to subjects' smoking. Parental opposition to smoking, beliefs that smoking was bad for health and a degree of self-esteem appeared to have protective value. The key to prevention of cigarette smoking may lie in parent and early childhood education aimed at increasing awareness of the dangers of smoking, fostering a soical climate of opposition to smoking, and increasing the child's self-confidence.

  11. The Decline of Menthol Cigarette Smoking in Australia, 1980–2008

    Introduction: Concerns have been expressed that menthol cigarettes are highly conducive to uptake and hence function as “starter cigarettes” for adolescents. There is strong evidence for this in the United States. If menthol cigarettes are critical to uptake for some adolescents, they might be expected to remain popular among adolescents independent of promotional activity. We analyzed trends in the market share of menthol brands in Australia among both adolescents and adults to provide further insights into the determinants of menthol cigarette smoking. Methods: We used the Australian Secondary Students Alcohol and Drug Survey (1984–2008), the Smoking and Health Survey (1980–1998), and the International Tobacco Control Four Nations Survey (2002–2008) to estimate market share of brands. Measures were reported use of all menthol brands for adults and use of the Alpine brand for adolescents. Results: Menthol smoking was much more popular among female smokers of all age groups in the early 1980s. During the 1980s and 1990s, use declined markedly in the 18–29 age groups, while remaining relatively stable among older smokers. Use of Alpine declined markedly among adolescents in the 1980s and 1990s. However, during this period, Alpine remained more popular among experimenting than regular smokers. Conclusions: Both Alpine and other menthol brands are now primarily “older women’s cigarettes” in Australia. The trends in declining popularity among younger smokers suggest that targeted marketing plays a major role in determining menthol brand market share. Alpine has played a role as a “starter” cigarette in Australia but that role has decreased markedly since the 1980s. Within the Australian context, “light/mild” brands may have taken over the role of easier-to-smoke cigarettes that attract experimenting smokers. PMID:22416116

    To describe electronic cigarette (e-cigarette) use and cigarette use among adolescents and determine whether established risk factors for smoking discriminate user categories. School-based survey of 1941 high school students (mean age 14.6 years) in Hawaii; data collected in 2013. The survey assessed e-cigarette use and cigarette use, alcohol and marijuana use, and psychosocial risk and protective variables (eg, parental support, academic involvement, smoking expectancies, peer smoking, sensation seeking). Analysis of variance and multinomial regression examined variation in risk and protective variables across the following categories of ever-use: e-cigarette only, cigarette only, dual use (use of both products), and nonuser (never used either product). Prevalence for the categories was 17% (e-cigarettes only), 12% (dual use), 3% (cigarettes only), and 68% (nonusers). Dual users and cigarette-only users were highest on risk status (elevated on risk factors and lower on protective factors) compared with other groups. E-cigarette only users were higher on risk status than nonusers but lower than dual users. E-cigarette only users and dual users more often perceived e-cigarettes as healthier than cigarettes compared with nonusers. This study reports a US adolescent sample with one of the largest prevalence rates of e-cigarette only use in the existing literature. Dual use also had a substantial prevalence. The fact that e-cigarette only users were intermediate in risk status between nonusers and dual users raises the possibility that e-cigarettes are recruiting medium-risk adolescents, who otherwise would be less susceptible to tobacco product use.

    Smoking has always been a huge problem in Malaysia and its surrounding nations. The purpose of this study was to determine the prevalence of cigarette smoking and to identify the influencing factors associated with smoking habits among adolescents. This cross-sectional study was carried out on 226 respondents, using a questionnaire which had 4 sections: socio-demographic data, personal information, family information and social information. Data was analyzed using SPSS® version 16. For categorical variables, comparisons were made using Chi-square and for numerical variables a t-test was performed. The current smoker prevalence rate was 20.8% which showed a significant association between smoking and individual factors: level of knowledge on the effects of smoking (p < 0.05), significant association was seen between smoking and marital status of parents, smoking status of male siblings and various other aspects of the individuals themselves. Concerted efforts involving various parties should be taken to curb or prevent this problem or the number of teenage smokers in the country will increase. This in the long run will invite problems to the well being of the adolescents themselves, their families, community and the nation as a whole.

    Using data from a study of high risk adolescents in Southern California, U.S.A. (N = 851), this study examined synergy between social network measures of social integration and peer influence in relation to past month cigarette smoking. Using Hierarchical Linear Modeling, results indicated that being central in networks was significantly and positively related to past month cigarette smoking, across all study models. In addition, there is modest evidence that the number of reciprocated friendship ties was positively related to past month cigarette smoking. There is also some modest evidence that the relationship between having reciprocated friendships and past month cigarette smoking was moderated by a network peer influence process, smoking with those in youths’ best friend networks. Findings indicate that being integrated within a social network context of peer influences favoring drug use relates to more smoking among these high risk youth. PMID:22436575

    Despite the harmful effects of cigarette smoking, this habit in asthmatic adolescents continues to be a health problem worldwide. Our objectives were to determine the epidemiological profile of smoking and the degree of nicotine dependence among asthmatic adolescents. Through a cross-sectional investigation, 3383 adolescents (13-19 years of age) were studied. Information was collected using a previously validated questionnaire. Two study groups of adolescent smokers were formed: one composed of asthmatic adolescents and the other of healthy youths. Asthmatic adolescents were found to be more likely to smoke (21.6% vs 11.8%) and to have some degree of nicotine dependence compared with healthy adolescents (51.6% vs 48.8%). The most important characteristic of smoking in asthmatic adolescents was found to be an onset before 11 years of age due to curiosity about cigarettes. Asthmatic youths continue smoking because this habit decreases their anxiety and stress. Adolescents know that smoking is addictive and often smoke on waking up in the morning or when they are sick. Yet, these adolescents do not consider smoking to be a problem. In this study, curiosity about cigarettes was the primary reason why asthmatic adolescents smoked for the first time and developed a greater dependence to nicotine compared with healthy adolescents. Moreover, the findings show that many of the factors that favour the development of smoking are preventable, given that they are present in the family and social environment.

    Electronic cigarettes (e-cigarettes) are rapidly emerging into a new trend among adolescents, signaling a new époque, that of vapers. E-cigarettes are battery-powered nicotine delivery devices that heat a typically flavoring liquid solution into an aerosol mist that users inhale, allowing them to imitate the act of conventional smoking. There are concerns about the impact of e-cigarettes at both individual and public health level. To discuss the characteristics of the most vulnerable, to become e-cigarette users, group of adolescents and to further highlight their behaviors and characteristics. An electronic search in PubMed, EMBASE, and Google Scholar databases was conducted, using combinations of the following keywords: adolescents, teenagers, e-cigarettes, vaping. The search included all types of articles written in English until August 2017. A total of 100 articles were found, and 25 were finally included in the present review. Older age, male gender, conventional smokers, peer influence, daily smoking, and heavier smoking are the most common characteristics of adolescent e-cigarette users. E-cigarette use is common, especially between certain subgroups in the adolescent population. Since e-cigarette use is increasing and considering that the long term health effects are still under investigation, targeted interventions towards more susceptible individuals may be an effective prevention strategy.

    The present study was a random-effects model meta-analysis of 26 studies published between 1990 and 2010 (k = 32; n = 39,777) that (a) examined the association between acculturation and cigarette smoking in Hispanic women and (b) evaluated age, national origin, and measure and dimensionality (unidimensional vs. bidimensional) of acculturation as moderating variables. Results indicate a strong positive relationship and suggest larger effects of acculturation on cigarette smoking in women of Mexican descent as compared with women originating from other Latin American countries for current and lifetime smoking, as well as smoking overall. The effect of acculturation on cigarette smoking was larger in adults as compared with adolescents for current smoking and smoking overall. Few differences in effect size by measure or dimensionality of acculturation emerged. Results are discussed with regard to implications for future research and the measurement of acculturation.

    Mentholated cigarettes are at least as dangerous to an individual's health as non-mentholated varieties. The addition of menthol to cigarettes reduces perceived harshness of smoke, which can facilitate initiation. Here, we examine correlates of menthol use, national trends in smoking menthol and non-menthol cigarettes, and brand preferences over time. We estimated menthol cigarette use during 2004-2010 using annual data on persons ≥12 years old from the National Surveys on Drug Use and Health. We adjusted self-reported menthol status for selected brands that were either exclusively menthol or non-menthol, based on sales data. Data were weighted to provide national estimates. Among cigarette smokers, menthol cigarette use was more common among 12-17 year olds (56.7%) and 18-25 year olds (45.0%) than among older persons (range 30.5% to 34.7%). In a multivariable analysis, menthol use was associated with being younger, female and of non-Caucasian race/ethnicity. Among all adolescents, the percentage who smoked non-menthol cigarettes decreased from 2004-2010, while menthol smoking rates remained constant; among all young adults, the percentage who smoked non-menthol cigarettes also declined, while menthol smoking rates increased. The use of Camel menthol and Marlboro menthol increased among adolescent and young adult smokers, particularly non-Hispanic Caucasians, during the study period. Young people are heavy consumers of mentholated cigarettes. Progress in reducing youth smoking has likely been attenuated by the sale and marketing of mentholated cigarettes, including emerging varieties of established youth brands. This study should inform the Food and Drug Administration regarding the potential public health impact of a menthol ban. Published by the BMJ Publishing Group Limited.

    ABSTRACT OBJECTIVE To estimate the prevalences of tobacco use, tobacco experimentation, and frequent smoking among Brazilian adolescents. METHODS We evaluated participants of the cross-sectional, nation-wide, school-based Study of Cardiovascular Risks in Adolescents (ERICA), which included 12- to 17-year-old adolescents from municipalities of over 100 thousand inhabitants. The study sample had a clustered, stratified design and was representative of the whole country, its geographical regions, and all 27 state capitals. The information was obtained with self-administered questionnaires. Tobacco experimentation was defined as having tried cigarettes at least once in life. Adolescents who had smoked on at least one day over the previous 30 days were considered current cigarette smokers. Having smoked cigarettes for at least seven consecutive days was an indicator for regular consumption of tobacco. Considering the complex sampling design, prevalences and 95% confidence intervals were estimated according to sociodemographic and socio-environmental characteristics. RESULTS We evaluated 74,589 adolescents. Among these, 18.5% (95%CI 17.7-19.4) had smoked at least once in life, 5.7% (95%CI 5.3-6.2) smoked at the time of the research, and 2.5% (95%CI 2.2-2.8) smoked often. Adolescents aged 15 to 17 years had higher prevalences for all indicators than those aged 12 to 14 years. The prevalences did not differ significantly between sexes. The highest prevalences were found in the South region and the lowest ones, in the Northeast region. Regardless of sex, the prevalences were found to be higher for adolescents who had had paid jobs, who lived with only one parent, and who reported having been in contact with smokers either inside or outside their homes. Female public school adolescents were found to smoke more than the ones from private schools. CONCLUSIONS Tobacco use among adolescents is still a challenge. Intending to reduce the prevalence of tobacco use among young

    Cross-sectional studies provide empirical support for associations between advertising and adolescent smoking. The aim of this study was to investigate the relationship between Spanish adolescent smoking behaviour and prior awareness of cigarette advertisements on billboards, using a prospective design. 3,664 Spanish children aged 13 and 14 years filled in self-completion questionnaires at baseline, and 6, 12, and 18 months later (cohort study). Slides of three advertisements were projected at baseline. A multivariate logistic regression analysis was carried out to detect possible association between number of identified tobacco advertisements brands at baseline and smoking status along time, controlling ASE Model smoking determinants, smoking prevention interventions, age, gender and socio-economic status. The more advertisements identified at baseline, the greater was the risk of being a smoker (p<0.0001). Final percentages of smokers were 15.8%, 16.3%, 19.3%, and 32.6%, respectively, for zero, one, two and three advertisements recognized. When confounders were controlled, the probability of being a smoker increased with the number of advertisements identified [OR 1.26 (95% CI: 1.09-1.46) after 6 months, OR 1.18 (95% CI: 1.03-1.35) after 12 months and 1.15 (95% CI: 1.02-1.30)] after 18 months. It is possible the association would have been even greater if there had not been a differential loss of smokers from the sample. Increased awareness of cigarette advertising was associated with a higher smoking incidence and an increased risk of Spanish children becoming smokers. It is, therefore, imperative that cigarette advertising should be banned as a matter of urgency.

    We conducted two experiments to examine the believability of three addiction-focused cigarette warnings and the influence of message source on believability among adolescents and adults in the United States. Experimental data were collected using national phone surveys of adolescents (age 13-17; n = 1125; response rate, 66%) and adults (age 18+; n = 5014; response rate, 42%). We assessed the believability of three cigarette warnings about addiction attributed to four message sources (Food and Drug Administration [FDA], Surgeon General, Centers for Disease Control and Prevention [CDC], no source). The majority of adolescents and adults reported the three cigarette warnings were very believable (49%-81% for adolescents; 47%-76% for adults). We found four to five times higher odds of adolescents believing a warning that cigarettes are addictive (warning 1) or that nicotine was an addictive chemical (warning 2) compared to a warning that differentiated the addictive risks of menthol versus traditional cigarettes (warning 3), warning 1 adjusted odds ratio (aOR): 4.53, 95% confidence interval (CI): 3.10, 6.63; warning 2 aOR: 3.87, 95% CI: 2.70, 5.50. Similarly, we found three to five times higher odds of adults (including current smokers) believing the same warnings, warning 1 aOR: 3.74, 95% CI: 2.82, 4.95; warning 2 aOR: 3.24, 95% CI: 2.45, 4.28. Message source had no overall impact on the believability of warnings for either population. Our findings support the implementation of FDA's required warnings that cigarettes are addictive and that nicotine is an addictive chemical. These believable warnings may deter adolescents from initiating smoking and encourage adults to quit smoking. This article describes, for the first time, the believability of different cigarette warnings about addiction. We now know that the majority of adolescents and adults believe cigarette warnings that highlight cigarettes as addictive and that nicotine is an addictive chemical in tobacco

    Introduction: Smoking can be conceptualized as an operant behavior maintained by the reinforcing effects of cigarettes. Changing the magnitude and availability of alternative reinforcers should shift behavior away from smoking. Adults’ smoking behavior is sensitive to the magnitude and availability of alternative reinforcers; however, the extent to which the same is true for adolescents has not yet been shown in the laboratory. Methods: To test the sensitivity of adolescent smoking behavior to changes in the magnitude of alternative reinforcement, we gave adolescents who abstained overnight the opportunity to make 20 choices between receiving two puffs of their usual-brand cigarette or money. The magnitude of the monetary reinforcer was varied across sessions in counterbalanced order ($0.00, $0.10, and $0.50). Results: Results indicated that adolescents’ choices for puffs decreased as a function of increasing monetary reinforcer magnitude, while money choices increased. This effect was moderated by baseline smoking level and by gender, such that heavier-smoking participants and males made more cigarette choices when the alternative monetary value was zero, and decreased their choices more steeply in response to increasing monetary value. Conclusions: The current study validates a laboratory choice procedure for studying smoking in adolescents, and demonstrates that adolescent smoking behavior is sensitive to changes in the magnitude of concurrently available monetary reinforcers. The current paradigm can be adapted and applied to explore the effects of other variables that may affect cigarette choice in adolescents. PMID:25666814

    Objective E-cigarettes are popular among youth, but little is known about the nicotine concentrations of e-liquids used by adolescents. Materials and Method In Spring, 2014, we conducted cross-sectional surveys in four Connecticut high schools and two middle schools. Among past-30-day e-cigarette users (n = 513, 45% female, mean age 15.9 [SD=1.4]), we examined what nicotine concentration adolescents typically used in their e-cigarettes (range 0-30mg/mL and “I don’t know”). We first examined whether age, sex, smoking status, e-cigarette use frequency, and/or e-cigarette acquisition source were associated with using nicotine-free e-liquid, nicotine e-liquid, or not knowing the e-liquid nicotine concentration. Among nicotine users (n = 185), we then examined whether the aforementioned variables were associated with using higher nicotine concentrations. Results Adolescents reported using nicotine-free e-liquid (28.5%), nicotine e-liquid (37.4%), or not knowing their e-liquid nicotine concentration (34.1%). Nicotine users comprised more smokers and heavier e-cigarette users compared to nicotine-free e-liquid users and those who did not know their nicotine concentration. Nicotine users also comprised more males and were more likely to purchase e-cigarettes online or from tobacco shops compared to those who did not know their nicotine concentration. Among nicotine users, cigarette smoking, male sex, and purchasing e-cigarettes from tobacco shops predicted using higher nicotine concentrations. Conclusions Adolescents reported using e-liquids with variable nicotine concentrations. Smokers, males, and those who purchased their own e-cigarettes reported using the highest nicotine levels. Of concern, many adolescents were unaware of the nicotine concentration in their e-liquid, raising concerns about inadvertent nicotine exposure among youth. PMID:27592270

    The present study was a random-effects model meta-analysis of 26 studies published between 1990 and 2010 (k = 32; n = 39,777) that (a) examined the association between acculturation and cigarette smoking in Hispanic women and (b) evaluated age, national origin, and measure and dimensionality (unidimensional vs. bidimensional) of acculturation as moderating variables. Results indicate a strong positive relationship and suggest larger effects of acculturation on cigarette smoking in women of Mexican descent as compared with women originating from other Latin American countries for current and lifetime smoking, as well as smoking overall. The effect of acculturation on cigarette smoking was larger in adults as compared with adolescents for current smoking and smoking overall. Few differences in effect size by measure or dimensionality of acculturation emerged. Results are discussed with regard to implications for future research and the measurement of acculturation.

    To assess the influence of smoking and tombak (local smokeless tobacco) dipping by parents, teachers and friends on cigarette smoking and tombak dipping by school-going Sudanese adolescents. This was a school-based cross-sectional survey was conducted in 2005-2006. Logistic regression was used for the analysis. A total of 4277 Sudanese school-going adolescents (aged 11-17 years) from 23 schools who completed an anonymous self-administered questionnaire on the use of tobacco products. Main outcome measures were self-reported tobacco use during the previous month defined current tobacco use. Ever smoking, tombak dipping and other tobacco products were also considered as outcomes. After adjusting for sex, age and school grade, adolescents' smoking habits were strongly associated with the habit in their parents and friends and, more weakly, with tombak dipping by teachers. When adjusted for each other, the association with smoking in friends was unaffected and remained significant (prevalence OR (POR) of having ever smoked was 1.94, 95% CI 1.64 to 2.29; OR of being current smoker was 3.77, 95% CI 2.80 to 5.07). Tobacco smoking in friends was positively associated with adolescents ever tombak dipping (POR 1.81, 95% CI 1.41 to 2.33) and current dipping (OR 3.33, 95% CI 2.20 to 5.05). The association with parental habits was reduced but still significantly elevated. Tombak dipping by teachers was only associated with adolescents ever tobacco smoking. Tobacco use by parents, teachers and friends was associated with adolescents' tobacco habits. The influence of friends was the strongest. In developing programmes against adolescents' tobacco habits, there is need to target the influence of these 'significant others'. Sudan needs to develop and implement comprehensive anti-smoking and anti-tombak dipping legislation to reduce the growing prevalence of such habits.

    Electronic cigarettes (e-cigarettes) are increasingly used by US adolescents and may be a gateway to traditional cigarette use. We examine rates of both products by age and examine differences in age-varying rates by sex and race/ethnicity. Data are from the 2014 National Youth Tobacco Survey, a national sample of US middle and high school students (n=22.007); students ages 11-19 were included. Past 30-day e-cigarette and traditional cigarette use were examined as a function of age; sex and race/ethnicity were included as moderators. The age-varying association between e-cigarette and traditional cigarette use was also examined. Rates of e-cigarette use increase faster than traditional cigarette use from ages 13-16. Compared to females, males had higher rates of e-cigarette use from ages 14-17.5 and traditional cigarette use from ages 15-18. Between ages 12-14, more Hispanic adolescents used e-cigarettes compared to White or Black adolescents; after age 14 Hispanics and Whites reported similar rates, peaking at twice the rate for Blacks. Hispanic adolescents report greater traditional cigarette use versus Whites between ages 12-13, but lower rates between ages 15-18. E-cigarette use was strongly associated with traditional cigarette use, particularly during early adolescence [OR>40 before age 12]. Young Hispanic adolescents are at elevated risk for use of e-cigarettes and traditional cigarettes during early adolescence. During early adolescence, youth using e-cigarettes are more likely to smoke traditional cigarettes compared to youth not using e-cigarettes. The study of age-varying effects holds promise for advancing understanding of disparities in health risk behaviors. Copyright © 2016 Elsevier Ltd. All rights reserved.

    To examine parental influences on two transitions in the adolescent smoking uptake process: from never having smoked to experimentation and from experimentation to established smoking. Using data from the longitudinal Teenage Attitudes and Practices Survey of 1989-1993, we related perceived parental concern about their adolescents' future smoking, parental smoking status, problem-solving communication between parent and adolescent, demographics, and other factors at baseline to experimentation by follow-up among those who had never puffed on a cigarette (n = 4149). We also related these factors at baseline to reaching a lifetime level of smoking of at least 100 cigarettes by follow up among those who had experimented but smoked < 100 cigarettes (n = 2684) in univariate and multivariate analyses. Among never-smokers, baseline susceptibility to smoking and having male best friends who smoke predicted experimentation in the next 4 years. Among experimenters, susceptibility to smoking, having male or female best friends who smoked, and lack of parental concern about future smoking distinguished those who progressed to established smoking by follow-up. Furthermore, communicating with parents first about serious problems was protective against progression from experimentation to established smoking. Interventions aimed at reducing adolescent smoking should encourage cessation for parents who smoke and help parents communicate strong anti-smoking norms to children and adolescents and maintain strong lines of communication with them.

    Purpose Using fMRI, we examined whether or not adolescents with low levels of nicotine exposure (light smokers) display neural activation in areas shown to be involved with addiction in response to smoking-related stimuli. Design/Setting/Participants Twelve adolescent light smokers (aged 13 to17, smoked 1 to 5 cigarettes per day) and 12 non-smokers (ages 13 to 17, never smoked a cigarette) from the San Francisco Bay Area underwent fMRI scanning. During scanning they viewed blocks of photographic smoking and control cues. Smoking cues consisted of pictures of people smoking cigarettes and smoking-related objects such as lighters and ashtrays. Neutral cues consisted of everyday objects and people engaged in everyday activities. Findings For smokers, smoking cues elicited greater activation than neutral cues in the mesolimbic reward circuit (left anterior cingulate (T=7.88, p<.001), right hippocampus (T=6.62, p<.001) and right parahippocampal gyrus (T=4.70, p<.001)). We found activation from smoking cues versus neutral cues within both the left and right frontal medial orbital regions (T=5.09, p<.001 and T=3.94, p=.001 respectively), which may be unique to adolescents. Non-smokers showed no significant difference in activation between smoking-related cues and neutral cues. Conclusions Our finding that smoking cues produced activation in adolescent light smokers in brain regions seen in adult and heavy teen smokers suggests that even at low levels of smoking, adolescents exhibit heightened reactivity to smoking cues. This paper adds to the existing literature suggesting that nicotine dependence may begin with exposure to low levels of nicotine, underscoring the need for early intervention among adolescent smokers.

    This article explores the role that personal values plays in motivating Taiwanese adolescents to smoke. In a nationwide survey of high school students, smokers attached greater importance to hedonic gratification values and less importance to idealism values than did nonsmokers. Hedonic gratification values were associated with favorable attitudes toward smoking, while idealism values were associated with unfavorable attitudes toward smoking. Attitudes toward smoking predicted adolescent smoking behavior. Evidence suggested that advertising plays an important role in motivating adolescents with hedonic gratification values to smoke. First, in the survey, hedonic gratification values were associated with paying attention to and expressing favorable attitudes toward cigarette advertising. Second, a content analysis of cigarette ads in magazines found hedonic gratification values to be the most commonly portrayed values, occurring in 62.7% of ads.

    Electronic (E-) cigarettes are one of the most popular tobacco products used by adolescents today. This study examined whether exposure to advertisements in (1) social networking sites (Facebook, Twitter, YouTube, Pinterest/Google Plus), (2) traditional media (television/radio, magazines, billboards), or (3) retail stores (convenience stores, mall kiosks, tobacco shops) was associated with subsequent e-cigarette use in a longitudinal cohort of adolescents. Data were drawn from longitudinal surveys conducted in fall 2013 (wave 1) and spring 2014 (wave 2) of a school-based cohort attending 3 high schools and 2 middle schools in Connecticut. Adolescents were asked about tobacco use behaviors and where they had recently seen e-cigarette advertising at wave 1. We used logistic regression to determine whether advertising exposure at wave 1 increased the odds of e-cigarette use by wave 2, controlling for demographics and cigarette smoking status at wave 1. Among those who have never used e-cigarettes in wave 1 (n = 1742), 9.6% reported e-cigarette use at wave 2. Multivariate logistic regression demonstrated that exposure to e-cigarette advertising on Facebook (OR 2.12 = p < 0.02) at wave 1, but not other venues, significantly increased the odds of subsequent e-cigarette use wave 2. Age, white race, and cigarette smoking at wave 1 also was associated with e-cigarette use at wave 2. This study provides one of the first longitudinal examinations demonstrating that exposure to e-cigarette advertising on social networking sites among youth who had never used e-cigarettes increases the likelihood of subsequent e-cigarette use.

    The perceived risks and benefits of smoking may play an important role in determining adolescents' susceptibility to initiating smoking. Our study examined the perceived risks and benefits of smoking among adolescents who demonstrated susceptibility or non susceptibility to smoking initiation. In October-November 2011, we conducted a population-based cross-sectional study in Jhaukhel and Duwakot Villages in Nepal. Located in the mid-hills of Bhaktapur District, 13 kilometers east of Kathmandu, Jhaukhel and Duwakot represent the prototypical urbanizing villages that surround Nepal's major urban centers, where young people have easy access to tobacco products and are influenced by advertising. Jhaukhel and Duwakot had a total population of 13,669, of which 15% were smokers. Trained enumerators used a semi-structured questionnaire to interview 352 randomly selected 14- to 16-year-old adolescents. The enumerators asked the adolescents to estimate their likelihood (0%-100%) of experiencing various smoking-related risks and benefits in a hypothetical scenario. Principal component analysis extracted four perceived risk and benefit components, excluding addiction risk: (i) physical risk I (lung cancer, heart disease, wrinkles, bad colds); (ii) physical risk II (bad cough, bad breath, trouble breathing); (iii) social risk (getting into trouble, smelling like an ashtray); and (iv) social benefit (looking cool, feeling relaxed, becoming popular, and feeling grown-up). The adjusted odds ratio of susceptibility increased 1.20-fold with each increased quartile in perception of physical Risk I. Susceptibility to smoking was 0.27- and 0.90-fold less among adolescents who provided the highest estimates of physical Risk II and social risk, respectively. Similarly, susceptibility was 2.16-fold greater among adolescents who provided the highest estimates of addiction risk. Physical risk I, addiction risk, and social benefits of cigarette smoking related positively, and physical risk

    Background A wide range of electronic cigarettes (e-cigarettes) are now on the market. We studied e-cigarette awareness and use, determinants and sources of e-cigarettes, the e-liquids used in them and exposure to e-cigarette advertisements among adolescents in Finland. Among smokers, we studied the association of e-cigarette use and interest in smoking cessation. Method Data were obtained from a national survey of 12–18-year-old Finnish adolescents in 2013 (N=3535, response rate 38%). Descriptive statistics and logistic regression analysis were used. Results Of the respondents, 85.3% knew what e-cigarettes were; 17.4% had tried them. E-liquids with nicotine were used most often (65.7%); also those who had never tried conventional cigarettes had used them. Of e-cigarette ever users, 8.3% had never tried smoking. Parents’ high level of education, being in employment, and intact family protected against children's e-cigarette use. In the final model, daily smoking (OR 41.35; 95% CI 25.2 to 67.8), snus use (2.96; 2.4–4.0), waterpipe use (2.21; 1.6–3.0), children's vocational education (2.06; 1.4–3.1) and poor school performance (1.92; 1.4–3.0) were associated with e-cigarette experimentation. Those smokers with most experience of e-cigarettes were least likely to consider smoking cessation. Conclusions Awareness and experimentation with e-cigarettes are high among adolescents, especially in older age groups and boys. Nicotine e-liquids are easy to acquire for youth. Having similar risk factors, e-cigarette use seems to follow the model of conventional smoking initiation. Among adolescent smokers, use of e-cigarettes does not clearly relate to interest in smoking cessation. Preventive policies are needed to protect the youth. PMID:24827977

    We examined the relationships between e-cigarette use and subsequent cigarette smoking behaviors at 6- and 12-month follow-ups among young adults. Participants were 18-29 year-old current and former cigarette smokers (N = 627) at 24 Texas colleges, participating in a 3-wave study. Multi-level, multivariable logistic regression models, accounting for school clustering, examined the impact of self-reported use of e-cigarettes on cigarette smoking status at 6- and 12-month follow-ups. Two mutually-exclusive groups of e-cigarette users were examined: those that used for cigarette smoking cessation and those that used for reasons other than cessation. Baseline covariates included socio-demographics, past quit attempts, nicotine dependence, cigarettes per day, and other tobacco use. Use of e-cigarettes for cigarette smoking cessation was associated with increased odds of cigarette smoking cessation at 6- and 12-month follow-ups, while using e-cigarettes for other reasons was not, when adjusting for covariates. Use of e-cigarettes for cigarette smoking cessation may reduce cigarette smoking rates in young adult college students. Additional research is needed examining e-cigarettes as a complement to evidence-based cessation resources that are associated with cigarette smoking cessation among young adults.

    We used longitudinal data to investigate the relationship between computer use in internet cafés and smoking/drinking behavior among Chinese adolescents and young adults. Data are from two waves of the China Health and Nutrition Survey (2004 and 2006). Fixed effects models were used to examine if changes in internet café use were associated with changes in cigarette smoking and drinking of alcohol. Male café users spent on average 17.3 hours in front of the computer/week. This was associated with an increase in the probability of being a current smoker by 13.3% and with smoking 1.7 more cigarettes. Female café users spent on average 11 hours on the computer/week. This was associated with an increase in the probability of drinking wine and/or liquor by 14.74% and was not associated with smoking. Internet cafés are an important venue by which adolescent and young adults in China are exposed to smoking and drinking. Multi-component interventions are needed ranging from policies regulating cigarette and alcohol availability in these venues to anti-tobacco campaigns aimed at the general population but also at individuals who frequent these establishments.

In a 2 × 2 between-subjects experiment, participants received a message about chemicals in cigarette smoke (e.g., "Cigarette smoke has benzene.") along with an additional randomly assigned messaging strategy: a "found-in" (e.g., "This is found in gasoline."), a health effect (e.g., "This causes heart disease."), both, or neither. Participants were U.S. probability phone samples of 5000 adults and 1123 adolescents, and an online convenience sample of 4130 adults. Adding a health effect elicited greater discouragement from wanting to smoke cigarettes (all p < .05) as did adding a found-in (all p < .05). However, including both messaging strategies added little or nothing above including just one. These findings can help the FDA and other agencies develop effective and parsimonious messages about cigarette smoke constituents.

  20. Social Psychological Factors in Adolescent Cigarette Smoking.

    Sherman, Steven J.; And Others

    Results emanating from smoking cessation programs suggest the necessity for a greater commitment to research for primary smoking prevention. Because of the early onset of smoking, more research must focus on adolescents and preadolescents who have not yet begun to smoke regularly. Three areas of concentrated study are proposed: (1) the initiation…

    More US adolescents use e-cigarettes than smoke cigarettes. Research suggests flavoured e-cigarettes appeal to youth, but little is known about perceptions of and reasons for attraction to specific flavours. A national sample of adolescents (n=1125) ages 13-17 participated in a phone survey from November 2014 to June 2015. We randomly assigned adolescents to respond to survey items about 1 of 5 e-cigarette flavours (tobacco, alcohol, menthol, candy or fruit) and used regression analysis to examine the impact of flavour on interest in trying e-cigarettes and harm beliefs. Adolescents were more likely to report interest in trying an e-cigarette offered by a friend if it were flavoured like menthol (OR=4.00, 95% CI 1.46 to 10.97), candy (OR=4.53, 95% CI 1.67 to 12.31) or fruit (OR=6.49, 95% CI 2.48 to 17.01) compared with tobacco. Adolescents believed that fruit-flavoured e-cigarettes were less harmful to health than tobacco-flavoured e-cigarettes (p<0.05). Perceived harm mediated the relationship between some flavours and interest in trying e-cigarettes. A minority of adolescents believed that e-cigarettes did not have nicotine (14.6%) or did not know whether they had nicotine (3.6%); these beliefs did not vary by flavour. Candy-flavoured, fruit-flavoured and menthol-flavoured e-cigarettes appeal to adolescents more than tobacco-flavoured or alcohol-flavoured e-cigarettes. This appeal is only partially explained by beliefs about reduced harm. Given adolescents' interest in trying e-cigarettes with certain flavours, policymakers should consider restricting advertisements promoting flavoured products in media that reach large numbers of young people. Future research should examine other reasons for the appeal of individual flavours, such as novelty and perceived luxury. Published by the BMJ Publishing Group Limited.

  2. Smoking in the movies increases adolescent smoking: a review.

    Despite voluntary restrictions prohibiting direct and indirect cigarette marketing to youth and paid product placement, tobacco use remains prevalent in movies. This article presents a systematic review of the evidence on the nature and effect of smoking in the movies on adolescents (and others). We performed a comprehensive literature review. We identified 40 studies. Smoking in the movies decreased from 1950 to approximately 1990 and then increased rapidly. In 2002, smoking in movies was as common as it was in 1950. Movies rarely depict the negative health outcomes associated with smoking and contribute to increased perceptions of smoking prevalence and the benefits of smoking. Movie smoking is presented as adult behavior. Exposure to movie smoking makes viewers' attitudes and beliefs about smoking and smokers more favorable and has a dose-response relationship with adolescent smoking behavior. Parental restrictions on R-rated movies significantly reduces youth exposure to movie smoking and subsequent smoking uptake. Beginning in 2002, the total amount of smoking in movies was greater in youth-rated (G/PG/PG-13) films than adult-rated (R) films, significantly increasing adolescent exposure to movie smoking. Viewing antismoking advertisements before viewing movie smoking seems to blunt the stimulating effects of movie smoking on adolescent smoking. Strong empirical evidence indicates that smoking in movies increases adolescent smoking initiation. Amending the movie-rating system to rate movies containing smoking as "R" should reduce adolescent exposure to smoking and subsequent smoking.

  3. Late adolescent female smoking.

    Although there have been intense efforts to reduce the prevalence of cigarette smoking in the past three decades, smoking continues to be a critical public health problem. An area of particular concern is the increasing number of young women who are smoking. Gender specific research usually does not examine factors affecting smoking behaviours. Information on late adolescent female smoking is not readily found in the literature. The aims of this study were to explore the smoking patterns and processes of late adolescent females and to explore factors which may or may not be helpful in assisting them to stop smoking. A qualitative ethnographic approach was used to uncover the perceptions of 25 adolescent girls of their behaviour. Data were collected using tape-recorded semi-structured interviews and a questionnaire. Items for the questionnaire were derived from the Manitoba Youth Smoking Survey and from the Fagerstrorn Nicotine Tolerance Scale. Qualitative analysis resulted in four stories about smoking: the start story, the smoking story, the quit story, and the looking to the future story. Although many of the findings are congruent with the existing literature, much of the data reflected the purposive nature of smoking in late adolescent girls. Study findings support the need for holistic approaches to health promotion to ameliorate factors affecting smoking behaviour.

    The aim of the study was to determine whether adolescents' intentions to smoke, cigarette smoking behavior, and specific perceptions of cigarette smoking are different in 2015 versus 2001. Data from two California school-based studies (X age  = 14) were compared: one conducted in 2001-2002 ("2001"), N = 395; the second in 2014-2015 ("2015"); N = 282. In 2015, more participants reported it was very unlikely they would smoke (94% vs. 65%) and that they never smoked (95% vs. 74%); they reported perceiving less likelihood of looking more mature (17% vs. 28%) and greater likelihood of getting into trouble (86% vs. 77%), having a heart attack (76% vs. 69%), and contracting lung cancer (85% vs. 78%) from smoking (p < .001). Perceptions of short-term health problems and addiction were similar in 2001 and 2015. Findings suggest that adolescents in 2015 perceived greater risks compared to those in 2001 even amidst the rapidly changing tobacco product landscape. In addition to continuing messages of long-term health risks, prevention efforts should include messages about addiction and short-term health and social risks.

  5. Examining unsupervised time with peers and the role of association with delinquent peers on adolescent smoking.

    2009-04-01

    This study explored the association between unsupervised time with peers and adolescent smoking behavior both directly and indirectly through interaction with delinquent peers, social expectancies about cigarette smoking, and cigarette offers from peers. A cross-sectional survey was used for the study and included 248 male and female middle school students. Results of structural equation modeling revealed that unsupervised time with peers is associated indirectly with adolescent smoking behavior through the mediation of association with delinquent peers, social expectancies about cigarette smoking, and cigarette offers from peers. Interventions designed to motivate adolescents without adult supervision to associate more with friends who engage in prosocial activities may eventually reduce adolescent smoking. Further implications for structured supervised time for students outside of school time are discussed.

    Characterizing smoking behavior is important for informing etiologic models and targeting prevention efforts. This study explored the effects of both individual- and community-level variables in predicting cigarette use vs. non-use and level of use among adolescents as they transition into adulthood. Data on 14,779 youths (53% female) were drawn from the National Longitudinal Study of Adolescent Health (Add Health); a nationally representative longitudinal cohort. A cohort sequential design allowed for examining trajectories of smoking typologies from age 13 to 32 years. Smoking trajectories were evaluated by using a zero-inflated Poisson (ZIP) latent growth analysis and latent class growth analysis modeling approach. Significant relationships emerged between both individual- and community-level variables and smoking outcomes. Maternal and peer smoking predicted increases in smoking over development and were associated with a greater likelihood of belonging to any of the four identified smoking groups versus Non-Users. Conduct problems and depressive symptoms during adolescence were related to cigarette use versus non-use. State-level prevalence of adolescent smoking was related to greater cigarette use during adolescence. Individual- and community-level variables that distinguish smoking patterns within the population aid in understanding cigarette use versus non-use and the quantity of cigarette use into adulthood. Our findings suggest that efforts to prevent cigarette use would benefit from attention to both parental and peer smoking and individual well-being. Future work is needed to better understand the role of variables in the context of multiple levels (individual and community-level) on smoking trajectories. Copyright © 2013 Elsevier Ireland Ltd.

    Objectives To compare adolescents’ responses to three different styles of cigarette packaging: novelty (branded packs designed with a distinctive shape, opening style or bright colour), regular (branded pack with no special design features) and plain (brown pack with a standard shape and opening and all branding removed, aside from brand name). Design Cross-sectional in-home survey. Setting UK. Participants Random location quota sample of 1025 never smokers aged 11–16 years. Main outcome measures Susceptibility to smoking and composite measures of pack appraisal and pack receptivity derived from 11 survey items. Results Mean responses to the three pack types were negative for all survey items. However, ‘novelty’ packs were rated significantly less negatively than the ‘regular’ pack on most items, and the novelty and regular packs were rated less negatively than the ‘plain’ pack. For the novelty packs, logistic regressions, controlling for factors known to influence youth smoking, showed that susceptibility was associated with positive appraisal and also receptivity. For example, those receptive to the innovative Silk Cut Superslims pack were more than four times as likely to be susceptible to smoking than those not receptive to this pack (AOR=4.42, 95% CI 2.50 to 7.81, p<0.001). For the regular pack, an association was found between positive appraisal and susceptibility but not with receptivity and susceptibility. There was no association with pack appraisal or receptivity for the plain pack. Conclusions Pack structure (shape and opening style) and colour are independently associated, not just with appreciation of and receptivity to the pack, but also with susceptibility to smoke. In other words, those who think most highly of novelty cigarette packaging are also the ones who indicate that they are most likely to go on to smoke. Plain packaging, in contrast, was found to directly reduce the appeal of smoking to adolescents. PMID:24056481

    E-cigarette use has dramatically increased. While studies have examined adolescents' attitudes towards smoking, few have extended this research to adolescents' attitudes towards e-cigarettes. The goal of this study was to examine adolescents' attitudes regarding e-cigarette ingredients, safety, addictive properties, social norms, accessibility, price, and regulation; and determine whether attitudes differ by past cigarette/e-cigarette use. Participants were 786 9th and 12th graders from California (63.21% females; mean age=16.10years [SD=1.6]; 26.61% White, 21.98% Asian/Pacific Islander, 29.82% Hispanic, and 21.59% other). Results indicated that 19.05% of participants believed smoke from e-cigarettes is water; 23.03% believed e-cigarettes aren't a tobacco product; 40.36% considered e-cigarettes to be for cessation, and 43.13% felt they were safer than cigarettes. Participants felt it was more acceptable to use e-cigarettes indoors and outdoors compared to cigarettes (p<0.0001), 23.13% felt raising e-cigarette taxes is a bad idea, 63.95% thought e-cigarettes were easier to get than cigarettes, 54.42% felt e-cigarettes cost too much, 64.33% felt the age for buying e-cigarettes should be raised, and 64.37% favored e-cigarette regulation. Adolescents who used e-cigarettes and/or cigarettes had significantly more favorable e-cigarette attitudes than non-users. This study indicates that adolescents are aware of some of the risks of e-cigarettes, although many harbor misperceptions and hold more favorable attitudes towards e-cigarettes than cigarettes. Of concern is the relationship between favorable e-cigarette attitudes and use. Findings suggest the need to provide adolescents with correct information about e-cigarette ingredients, risks, and the insufficient evidence of their role in cigarette cessation.

    The study objectives were to examine smoking abstinence and reinstatement effects on subjective experience and cognitive performance among adolescent smokers. Adolescents (aged 14-17 years, 60 daily smokers and 32 nonsmokers) participated. Participants completed baseline assessments (Session 1) and returned to the laboratory 1-3 days later to repeat assessments (Session 2); half of the smokers were randomly assigned to 15-17 hr tobacco abstinence preceding Session 2. During Session 2, abstaining smokers reported significantly greater increases in withdrawal symptoms, smoking urges, and negative affect compared with smokers who did not abstain and compared with nonsmokers. Smoking reinstatement reversed abstinence effects, returning to baseline levels for smoking urges and negative affect. Abstaining smokers showed significantly enhanced cognitive performance on two of six tasks (two-letter search compared with nonabstaining smokers; serial reaction time compared with nonsmokers); smoking reinstatement resulted in significant decrements on these two tasks relative to nonabstaining smokers. Effects of smoking abstinence and reinstatement on self-report measures are consistent with earlier research with adolescent as well as adult smokers and may help to elucidate the motivational underpinnings of smoking maintenance among adolescent smokers. Effects found on cognitive performance were contrary to hypotheses; further research is needed to understand better the role of cognitive performance effects in smoking maintenance among adolescents.

    Purpose Electronic cigarettes (e-cigarettes) are a new type of device that delivers vaporized nicotine without the tobacco combustion of regular cigarettes. We sought to understand awareness of and willingness to try e-cigarettes among adolescent males, a group that is at risk for smoking initiation and may use e-cigarettes as a “gateway” to smoking. Methods A national sample of 11–19-year-old males (n =228) completed an online survey in November 2011. We recruited participants through their parents, who were members of a panel of U.S. households constructed using random-digit dialing and addressed-based sampling. Results Only two participants (< 1%) had previously tried e-cigarettes. Among those who had not tried e-cigarettes, most (67%) had heard of them. Awareness was higher among older and non- Hispanic adolescents. Nearly 1 in 5 (18%) participants were willing to try either a plain or flavored e-cigarette, but willingness to try plain versus flavored varieties did not differ. Smokers were more willing to try any e-cigarette than nonsmokers (74% vs. 13%; OR 10.25, 95% CI 2.88, 36.46). Nonsmokers who had more negative beliefs about the typical smoker were less willing to try e-cigarettes (OR .58, 95% CI .43, .79). Conclusions Most adolescent males were aware of e-cigarettes, and a substantial minority were willing to try them. Given that even experimentation with e-cigarettes could lead to nicotine dependence and subsequent use of other tobacco products, regulatory and behavioral interventions are needed to prevent “gateway” use by adolescent nonsmokers. Campaigns promoting negative images of smokers or FDA bans on sales to youth may help deter use. PMID:23332477

    To estimate the price elasticity of cigarette demand among youth in low- and middle-income countries (LMIC). The Global Youth Tobacco Survey was used to obtain data on the smoking behaviour of 315,353 adolescents from 17 LMIC. Two-part model of cigarette demand with country fixed effects. The first part estimates the impact of prices on smoking participation while the second part estimates the impact of prices on the number of cigarettes smoked among current smokers. Besides controlling for individual characteristics such as Age, Gender, Parental Smoking and availability of Pocket Money, the authors control for confounding environmental factors such as anti-smoking sentiment, the prevalence of cigarette advertising and anti-tobacco media messAges, and ease of purchasing cigarettes. All countries in this study are represented with at least two observations over time, which allows us to control for unobserved country characteristics and/or policies that may influence smoking patterns within countries. Cigarette price is an important determinant of smoking. The estimated price elasticity of smoking participation is -0.74, and the estimated price elasticity of conditional cigarette demand is approximately -1.37. The total price elasticity of cigarette demand is -2.11, implying that an increase in price of 10% would reduce youth cigarette consumption by 21.1% at the mean.

    Background Much attention has been directed towards the possible effects of e-cigarette advertisements on adolescent never smokers. However, e-cigarette advertising may also influence perceptions and behaviors of adult smokers. The aim of our study was to examine whether noticing e-cigarette advertisements is associated with current use of e-cigarettes, disapproval of smoking, quit smoking attempts, and quit smoking success. Methods We used longitudinal data from two survey waves of the ITC Netherlands Survey among smokers aged 16 years and older (n=1198). Respondents were asked whether they noticed e-cigarettes being advertised on television, on the radio, and in newspapers or magazines in the previous 6 months. Results There was a significant increase in noticing e-cigarette advertisements between 2013 (13.3%) and 2014 (36.0%), across all media. The largest increase was for television advertisements. There was also a substantial increase in current use of e-cigarettes (from 3.1% to 13.3%), but this was not related to noticing advertisements in traditional media (OR=0.99, p=0.937). Noticing advertisements was bivariately associated with more disapproval of smoking (Beta=0.05, p=0.019) and with a higher likelihood of attempting to quit smoking (OR=1.37, p=0.038), but these associations did not reach significance in multivariate analyses. There was no significant association between noticing advertisements and quit smoking success in either the bivariate or multivariate regression analysis (OR=0.92, p=0.807). Conclusion Noticing e-cigarette advertisements increased sharply in the Netherlands between 2013 and 2014 along with increased e-cigarette use, but the two appear unrelated. The advertisements did not seem to have adverse effects on disapproval of smoking and smoking cessation. PMID:26818084

    Electronic cigarettes are marketed as a tool to give up or reduce cigarette smoking, and their use has risen sharply in recent years. There is concern that use is increasing particularly among adolescents and that they are not being used as a cessation tool but as a novel experience in their own right. The present research assessed prevalence and sociodemographic correlates of e-cigarette use and standard cigarette use and also explored the extent to which e-cigarettes appear to be used as a cessation tool. This was assessed using a questionnaire administered to 1,486 French adolescents aged 16 years. Prevalence of e-cigarette experimentation was high (54%) and comparable to that for standard cigarettes (55%). Furthermore, 20% of those who had experimented with e-cigarettes had never tried standard cigarettes, and among regular smokers of standard cigarettes, intentions to quit were not associated with e-cigarette usage frequency. Experimentation with both e-cigarettes and standard cigarettes was significantly predicted by higher age, higher socioeconomic status, and parental smoking of standard cigarettes (in particular the father). Being male marginally predicted e-cigarette use, whereas being female significantly predicted standard cigarette use. These findings give cause for concern: e-cigarette usage experimentation is extremely high, and is not associated with attempts to quit smoking standard cigarettes. Rather, it is exposing adolescents to a highly addictive drug (nicotine) and may pave the way for a future cigarette habit. Copyright © 2016 Society for Adolescent Health and Medicine.

    Coordinated high-impact interventions and community-level changes in smoking behaviour norms effectively reduced prevalence of smoking among youth in many developed countries. Smoking trends among Jordanian adolescents are likely different than their Western counterparts and must be understood in the context of their daily lives to tailor interventions specifically for adolescents in this setting. Between 2008 and 2011, a school-based longitudinal study was conducted in Irbid, Jordan. All seventh-grade students in 19 randomly selected schools (of 60) were surveyed annually for 4 years. Outcomes of interest were time trends in smoking behaviour, age at initiation and change in frequency of smoking. Among 1781 participants, baseline prevalence of current smoking (cigarettes or waterpipe) for boys was 22.9% and 8.7% for girls. Prevalence of ever-smoking and current any smoking, cigarette smoking, waterpipe smoking and dual cigarette/waterpipe smoking was significantly higher in boys than girls each year (P < 0.001). Smoking prevalence increased every year after year 2 for current smoking (P < 0.05) across all methods (any, cigarette, waterpipe and dual). At all time points for both boys and girls, prevalence of waterpipe smoking was higher than that of cigarette smoking (P < 0.001). This study shows intensive smoking patterns at early ages among Jordanian youth in Irbid, characterized by a predominance of waterpipe smoking and steeper age-related increase in cigarette smoking. It also points to the possibility of waterpipe being the favourite method for introducing youth to tobacco, as well as being a vehicle for tobacco dependence and cigarette smoking.

    We used longitudinal data to investigate the relationship between computer use in internet cafés and smoking/drinking behavior among Chinese adolescents and young adults. Data are from two waves of the China Health and Nutrition Survey (2004 and 2006). Fixed effects models were used to examine if changes in internet café use were associated with changes in cigarette smoking and drinking of alcohol. Male café users spent on average 17.3 hours in front of the computer/week. This was associated with an increase in the probability of being a current smoker by 13.3% and with smoking 1.7 more cigarettes. Female café users spent on average 11 hours on the computer/week. This was associated with an increase in the probability of drinking wine and/or liquor by 14.74% and was not associated with smoking. Internet cafés are an important venue by which adolescent and young adults in China are exposed to smoking and drinking. Multi-component interventions are needed ranging from policies regulating cigarette and alcohol availability in these venues to anti-tobacco campaigns aimed at the general population but also at individuals who frequent these establishments.

    Dioxins in cigarettes, smoke, and ash were determined using gas chromatography/mass spectrometry. The total concentration of polychlorinated dibenzo-p-dioxins (PCDDs) in cigarette smoke was approximately 5.0 micrograms/m3 at the maximum level, whereas various congeners from tetra-octa-chlorodibenzo-p-dioxin (-CDD) were detected. Particullary, the total concentration of hepta-CDD congeners was the highest among these congeners. Mass fragmentograms of various PCDD congeners were similar to those in flue gas samples collected from a municipal waste incinerator. The PCDD congeners that were not present in the cigarettes were found in the smoke samples. The 2,3,7,8-TCDD toxic equivalent value--an index for effects on humans--for total PCDDs inmore » smoke was 1.81 ng/m3 using the toxic factor of the United States Environment Protection Agency. Daily intake of PCDDs by smoking 20 cigarettes was estimated to be approximately 4.3 pg.kg body weight/day. This value was close to that of the ADIs: 1-5 pg.kg body weight/day reported in several countries. A heretofore unrecognized health risk was represented by the presence of PCDDs in cigarette smoke.« less

    A wide range of electronic cigarettes (e-cigarettes) are now on the market. We studied e-cigarette awareness and use, determinants and sources of e-cigarettes, the e-liquids used in them and exposure to e-cigarette advertisements among adolescents in Finland. Among smokers, we studied the association of e-cigarette use and interest in smoking cessation. Data were obtained from a national survey of 12-18-year-old Finnish adolescents in 2013 (N=3535, response rate 38%). Descriptive statistics and logistic regression analysis were used. Of the respondents, 85.3% knew what e-cigarettes were; 17.4% had tried them. E-liquids with nicotine were used most often (65.7%); also those who had never tried conventional cigarettes had used them. Of e-cigarette ever users, 8.3% had never tried smoking. Parents' high level of education, being in employment, and intact family protected against children's e-cigarette use. In the final model, daily smoking (OR 41.35; 95% CI 25.2 to 67.8), snus use (2.96; 2.4-4.0), waterpipe use (2.21; 1.6-3.0), children's vocational education (2.06; 1.4-3.1) and poor school performance (1.92; 1.4-3.0) were associated with e-cigarette experimentation. Those smokers with most experience of e-cigarettes were least likely to consider smoking cessation. Awareness and experimentation with e-cigarettes are high among adolescents, especially in older age groups and boys. Nicotine e-liquids are easy to acquire for youth. Having similar risk factors, e-cigarette use seems to follow the model of conventional smoking initiation. Among adolescent smokers, use of e-cigarettes does not clearly relate to interest in smoking cessation. Preventive policies are needed to protect the youth.

    Cigarette smoking is a behavior with profound biomedical and psychosocial consequences across the life span. Although it is advertised in terms of youth, beauty, sexual appeal, success and independence, smoking is intimately linked with addiction, disease and death. Smoking has been shown to be a leading contributer to several kinds of cancer,…

    This study evaluates four measures of exposure to retail cigarette marketing in relation to adolescent smoking behavior. The measures are (a) shopping frequency in types of stores known to carry more cigarette advertising than other store types, (b) shopping frequency in specific stores that sell cigarettes in the study community, (c) the amount of exposure to cigarette brand impressions in stores where students shopped, and (d) perceived exposure to cigarette advertising. The study combined data from classroom surveys administered to 6th-, 7th-, and 8th-grade students in three California middle schools, and direct store observations quantifying cigarette marketing materials and product placement in stores where students shopped. Logistic regression models were used to examine how each exposure measure related to the odds of ever smoking and susceptibility to smoke, controlling for grade, gender, ethnicity, school performance, unsupervised time, and exposure to household and friend smoking. Frequent exposure to retail cigarette marketing as defined by each of the four measures was independently associated with a significant increase in the odds of ever smoking. All but the measure of exposure to store types was associated with a significant increase in the odds of susceptibility to smoke. Four measures of exposure to retail cigarette marketing may serve equally well to predict adolescent smoking but may vary in cost, complexity, and meaning. Depending on the outcomes of interest, the most useful measure may be a combination of self-reported exposure to types of stores that contain cigarette marketing and perceived exposure to such messages.

    Introduction Electronic cigarette (e-cigarette) use prevalence is increasing among U.S. adolescents and adults but recent longitudinal data for college/university students are scarce. Furthermore, the extent that e-cigarette use is associated with the onset of cigarette smoking and the factors that lead to the uptake of e-cigarettes in college students has not been explored. Methods 3,757 participants from a Mid-Atlantic university (women: 66%; White: 45%; Black: 21%; Asian: 19%; Hispanic/Latino: 6%) were surveyed in 2014 and again in 2015. Results Among participants reporting never smoking at time 1, those who had ever tried e-cigarettes or were currently using e-cigarettes (at least one use in past 30 days) were more likely to have ever tried cigarettes by time 2 relative to individuals who had not used e-cigarettes. Ever use of e-cigarettes (but not current use) also increased participants’ likelihood of being current cigarette smokers at time 2. Among initial never users of e-cigarettes or cigarettes, males and ever marijuana users had an increased probability of trying e-cigarettes by time 2. Furthermore, less perseverance (an index of impulsivity) and ever use of other tobacco products increased initial never users’ chances of trying both cigarettes and e-cigarettes by time 2. Conclusions Given that never-smoking participants who had tried e-cigarettes were more likely to initiate cigarette use later, limiting young adults’ access to these products may be beneficial. As the long-term health implications of e-cigarette use become clearer, predictors of e-cigarette use could help identify future populations likely to use and abuse these products. PMID:28038364

    Introduction The present study examined the influence of flavouring on the smoking and vaping behaviour of cigarette smokers asked to adopt e-cigarettes for a period of 6 weeks. Methods Participants were 88 current male and female smokers with no intention to stop smoking, but who agreed to substitute e-cigarettes for their current cigarettes. On intake, participants were administered tests of taste and smell for e-cigarettes flavoured with tobacco, menthol, cherry and chocolate, and were given a refillable e-cigarette of their preferred flavour or a control flavour. Participants completed daily logs of cigarette and e-cigarette use and were followed each week. Results Analyses over days indicated that, during the 6-week e-cigarette period, cigarette smoking rates dropped from an average of about 16 to about 7 cigarettes/day. e-Cigarette flavour had a significant effect such that the largest drop in cigarette smoking occurred among those assigned menthol e-cigarettes, and the smallest drop in smoking occurred among those assigned chocolate and cherry flavours. e-Cigarette vaping rates also differed significantly by flavour assigned, with the highest vaping rates for tobacco- and cherry-flavoured e-cigarettes, and the lowest rates for those assigned to chocolate. Conclusions The findings suggest that adoption of e-cigarettes in smokers may influence smoking rates and that e-cigarette flavourings can moderate this effect. e-Cigarette vaping rates are also influenced by flavourings. These findings may have implications for the utility of e-cigarettes as a nicotine replacement device and for the regulation of flavourings in e-cigarettes for harm reduction. PMID:27633766

  3. Is there differential responsiveness to a future cigarette price increase depending on adolescents' source of cigarette access?

    We examined whether the responsiveness to an increase in cigarettes price differed by adolescents' cigarette acquisition source. We analyzed data on 6134 youth smokers (grades 7-12) from a cross-sectional survey in Korea with national representativeness. The respondents were classified into one of the following according to their source of cigarette acquisition: commercial-source group, social-source group, and others. Multiple logistic regressions were performed to estimate the effects of an increase in cigarette price on the intention to quit smoking on the basis of the cigarette acquisition source. Of the 6134 youth smokers, 36.0% acquired cigarettes from social sources, compared to the 49.6% who purchased cigarettes directly from commercial sources. In response to a future cigarette price increase, regardless of an individual's smoking level, there was no statistically significant difference in the odds ratio for the intention to stop smoking in association with cigarette acquisition sources. The social-source group had nonsignificant, but consistently positive, odds ratios (1.07-1.30) as compared to that of the commercial-source group. Our findings indicate that the cigarette acquisition source does not affect the responsiveness to an increase in cigarette price. Therefore, a cigarette price policy is a comprehensive strategy to reduce smoking among youth smokers, regardless of their source.

    To examine how adolescents' inattentive behaviour, together with parental smoking patterns, predicts smoking initiation by age 14. DESIGN, SETTINGS: A prospective, longitudinal study: baseline at ages 11-12, follow-up at age 14. A population-based sample of Finnish twins, born 1983-1987, with parents and classroom teachers as additional informants. Two groups were formed, allocating the co-twins of each family into separate groups: the study sample and a replication sample. Twin individuals (n = 4552), aged 11-12 at baseline and 14 (average 14.04 years) at follow-up. At baseline, inattentiveness was assessed with the Multidimensional Peer Nomination Inventory (MPNI, Teacher Form) and parental smoking with individual questionnaires completed by each twins' parents; at the age 14 follow-up, adolescent smoking was assessed with a self-report questionnaire. At age 14, 57% reported never having smoked, 34% had experimented with cigarettes and 9% were current smokers. Inattentiveness and parental smoking additively predicted both experimental and current smoking in adolescence. The effects were independent of each other. The risk related to inattentiveness itself is high, but in combination with the effects of parental smoking, the probability of current smoking can rise as high as 38%, compared with 5% without these two risk factors. For prevention purposes, parental commitment to non-smoking should be emphasized.

    There is concern that e-cigarette use could be a risk factor for subsequent cigarette smoking. This survey included a group of 1220 students at Aix-Marseille University who attended a check-up visit and volunteered to participate to the survey. They answered a standardized questionnaire relating to e-cigarette use, smoking habits and the relationship between both habits. Mean age of participants was 19.9 years and 56% of them were female. All students invited to the check-up examination attended and agreed to participate in the survey. 13.3% of students answered they had already used e-cigarettes, a higher proportion of boys (17.5%) than girls (10.0%), starting at a mean age equal to 19.2 years. Forty-six percent of them had already smoked cigarettes, more girls (55.0%) than boys (45.0%). Among current cigarette smokers, e-cigarette use had induced giving up smoking in 12.6% and a decrease in the number of cigarettes smoked in 30.1%. Twenty percent said they begun to smoke cigarettes after using e-cigarettes. E-cigarette use is much less prevalent than smoking conventional tobacco cigarettes. There is a strong link between both. E-cigarette use had allowed a cessation or reduction in tobacco smoking in half of users. E-cigarette users may go on to start tobacco smoking but prospective surveys are needed to know how this will evolve over time. E-cigarette use could also be a means to prevent or postpone cigarette smoking. Copyright © 2015 SPLF. Published by Elsevier Masson SAS. All rights reserved.

    Existing studies showing an association between substance use disorders and Internet addiction have been limited due their cross-sectional design. This longitudinal study investigated the association between addictive Internet use during adolescence and heavy drinking and cigarette smoking in early adulthood. We focused on middle school students from the Korea Youth Panel Study who were 15 in 2003:1804 who did not drink alcohol and 2277 who did not smoke. Multivariate logistic analysis investigated the relationships between Internet use at the age of 15, with regard to location, time spent and reason for use, and drinking and smoking at the age of 20. Using the Internet for chatting, games and adult websites at the age of 15 had a significant association with heavy drinking at the age of 20. The Internet café as the location for Internet use at the age of 15 was associated with smoking behaviour at the age of 20. This study confirmed significant associations between addictive use of the Internet at the age of 15 and heavy drinking and cigarette smoking at the age of 20. The findings demonstrated the negative effects of addictive Internet use, one of the biggest problems with adolescents. ©2016 Foundation Acta Paediatrica. Published by John Wiley & Sons Ltd.

    Cigarette smoking is common in adolescents with attention-deficit/hyperactivity disorder (ADHD) and substance use disorders (SUD). However, little is known about the relationship between cigarette and cannabis use trajectories in the context of treatment for both ADHD and SUD. To address this research gap, we report collateral analyses from a 16-week randomized, controlled trial (n=303) of osmotic-release methylphenidate (OROS-MPH) in adolescents with ADHD concurrently receiving cognitive behavioral therapy (CBT) targeting non-nicotine SUD. Participants completed cigarette and cannabis use self-report at baseline and throughout treatment. Analyses were performed to explore the relationships between cigarette smoking, cannabis use, and other factors, such as medication treatment assignment (OROS-MPH versus placebo). Baseline (pre-treatment) cigarette smoking was positively correlated with cannabis use. Negligible decline in cigarette smoking during treatment for non-nicotine SUD was observed in both medication groups. Regular cigarette and cannabis users at baseline who reduced their cannabis use by >50% also reduced cigarette smoking (from 10.8±1.1 to 6.2±1.1 cigarettes per day). Findings highlight the challenging nature of concurrent cannabis and cigarette use in adolescents with ADHD, but demonstrate that changes in use of these substances during treatment may occur in parallel.

    Cigarette smoking in cocaine users is nearly four times higher than the national prevalence and cocaine use increases cigarette smoking. The mechanisms underlying cigarette smoking in cocaine-using individuals need to be identified to promote cigarette and cocaine abstinence. Previous studies have examined the salience of cigarette and cocaine cues separately. The present aim was to determine whether cigarette attentional bias (AB) is higher in cigarettes smokers who smoke cocaine relative to individuals who only smoke cigarettes. Twenty cigarette smokers who smoke cocaine and 20 non-cocaine-using cigarette smokers completed a visual probe task with eye-tracking technology. During this task, the magnitude of cigarette and cocaine AB was assessed through orienting bias, fixation time, and response time. Cocaine users displayed an orienting bias towards cigarette cues. Cocaine users also endorsed a more urgent desire to smoke to relieve negative affect associated with cigarette craving than non-cocaine users (g = 0.6). Neither group displayed a cigarette AB, as measured by fixation time. Cocaine users, but not non-cocaine users, displayed a cocaine AB as measured by orienting bias (g = 2.0) and fixation time (g = 1.2). There were no significant effects for response time data. Cocaine-smoking cigarettes smokers display an initial orienting bias toward cigarette cues, but not sustained cigarette AB. The incentive motivation underlying cigarette smoking also differs. Cocaine smokers report more urgent desire to smoke to relieve negative affect. Identifying differences in motivation to smoke cigarettes may provide new treatment targets for cigarette and cocaine use disorders. These results suggest that cocaine-smoking cigarette smokers display an initial orienting bias towards cigarette cues, but not sustained attention towards cigarette cues, relative to non-cocaine-using smokers. Smoked cocaine users also report a more urgent desire to smoke to relieve negative affect

    Objectives Given that many adolescent e-cigarette users are never-smokers, the possibility that e-cigarettes may act as a gateway to future cigarette smoking has been discussed in various studies. Longitudinal data are needed to explore the pathway between e-cigarette and cigarette use, particularly among different risk groups including susceptible and non-susceptible never-smokers. The objective of this study was to examine whether baseline use of e-cigarettes among a sample of never-smoking youth predicted cigarette smoking initiation over a 2-year period. Design Longitudinal cohort study. Setting 89 high schools across Ontario and Alberta, Canada. Participants A sample of grade 9–11 never-smoking students at baseline (n=9501) who participated in the COMPASS study over 2 years. Primary and secondary outcome measures Participants completed in-class questionnaires that assessed smoking susceptibility and smoking initiation. Results Among the baseline sample of non-susceptible never-smokers, 45.2% of current e-cigarette users reported trying a cigarette after 2 years compared with 13.5% of non-current e-cigarette users. Among the baseline sample of susceptible never-smokers, 62.4% of current e-cigarette users reported trying a cigarette after 2 years compared with 36.1% of non-current e-cigarette users. Overall, current e-cigarette users were more likely to try a cigarette 2 years later. This association was stronger among the sample of non-susceptible never-smokers (AOR=5.28, 95% CI 2.81 to 9.94; p<0.0001) compared with susceptible never-smokers (AOR=2.78, 95% CI 1.84 to 4.20; p<0.0001). Conclusions Findings from this large, longitudinal study support public health concerns that e-cigarette use may contribute to the development of a new population of cigarette smokers. They also support the notion that e-cigarettes are expanding the tobacco market by attracting low-risk youth who would otherwise be unlikely to initiate using cigarettes. Careful

    Identification of the causal impact of self-esteem on smoking stages faces seemingly insurmountable problems in observational data, where self-esteem is not manipulable by the researcher and cannot be assigned randomly. The aim of this study was to find out if weaker self-esteem in adolescence is a risk factor of cigarette smoking in a longitudinal study in Iran. In this longitudinal study, 4,853 students (14-18 years) completed a self-administered multiple-choice anonym questionnaire. The students were evaluated twice, 12 months apart. Students were matched based on coarsened exact matching on pretreatment variables, including age, gender, smoking stages at the first wave of study, socioeconomic status, general risk-taking behavior, having a smoker in the family, having a smoker friend, attitude toward smoking, and self-injury, to ensure statistically equivalent comparison groups. Self-esteem was measured using the Rosenberg 10-item questionnaire and were classified using a latent class analysis. After matching, the effect of self-esteem was evaluated using a multinomial logistic model. In the causal fitted model, for adolescents with weaker self-esteem relative to those with stronger self-esteem, the relative risk for experimenters and regular smokers relative to nonsmokers would be expected to increase by a factor of 2.2 (1.9-2.6) and 2.0 (1.5-2.6), respectively. Using a causal approach, our study indicates that low self-esteem is consistently associated with progression in cigarette smoking stages.

    The studies presented in this manuscript evaluated the role that affect and the self-concept play in adolescent never smokers' reactions to the gender valence of cigarette advertising imagery. Study 1 (n=29; 59% female) revealed that adolescent females have more positive affective reactions to female-valenced cigarette advertising imagery compared to male-valenced cigarette advertising imagery. Study 2 (n=101; 56% female) revealed that adolescent females viewed female-valenced cigarette advertising imagery as more relevant to their self-concepts compared to male-valenced cigarette advertising imagery. Across both studies, male adolescents did not respond differently as a function of the gender valence of cigarette advertising imagery. Thus, female-valenced cigarette advertising imagery may have specific effects on never smoking female adolescents by enhancing positive affect and suggesting that women who smoke hold the same characteristics as do the young women themselves.

    Background Very few studies have examined the role of school, household and family contexts in youth smoking in middle-income countries. Methods This work describes smoking exposure among 59 992 high school students who took part in the Brazilian Survey of School Health and investigates contextual factors associated with regular smoking, defined as smoking cigarettes at least once in the past 30 days. The explaining variables were grouped into: socio-demographic characteristics, school context, household context and family rapport. Variables independently associated with smoking in each context were identified by multiple logistic regression analysis. Results 53% of the total sample were girls, 89% were aged 13–15 years. 24% had already experimented with cigarettes, 50% before the age of 12 years. The prevalence of regular smoking was 6.3% (95% CI 5.87 to 6.74), with no sex variation. Smoking was not associated with either the mother's education or the index of household assets. In the multivariable analysis, studying at a private school, the possibility of purchasing cigarettes at school and skipping of classes without parents' consent increased the chances of smoking. In the household context, living with both parents was negatively associated with smoking, while having smoking parents and exposure to other people's smoking was positively related to smoking. In the family context, parental unawareness of what the adolescent was doing increased smoking, but having meals with the mother one or more days per week and parents' negative reactions to adolescent smoking reduced the chances of smoking. Conclusion The results reinforce the role of school, household and family contexts in youth smoking behaviours and will help improve public health policies aimed at preventing smoking and health promotion in adolescents.

    E-cigarette use among adolescents is on the rise in the U.S. However, limited attention has been given to examining the role of race, citizenship status and language spoken at home in shaping e-cigarette use behavior. Data are from the 2014 Adolescent California Health Interview Survey, which interviewed 1052 adolescents ages 12-17. Lifetime e-cigarette use was examined by sociodemographic characteristics. Separate logistic regression models predicted odds of ever-smoking e-cigarettes from race, citizenship status and language spoken at home. Sociodemographic characteristics were then added to these models as control variables and a model with all three predictors and controls was run. Similar models were run with conventional smoking as an outcome. 10.3% of adolescents ever used e-cigarettes. E-cigarette use was higher among ever-smokers of conventional cigarettes, individuals above 200% of the Federal Poverty Level, US citizens and those who spoke English-only at home. Multivariate analyses demonstrated that citizenship status and language spoken at home were associated with lifetime e-cigarette use, after accounting for control variables. Only citizenship status was associated with e-cigarette use, when controls variables race and language spoken at home were all in the same model. Ever use of e-cigarettes in this study was higher than previously reported national estimates. Action is needed to curb the use of e-cigarettes among adolescents. Differences in lifetime e-cigarette use by citizenship status and language spoken at home suggest that less acculturated individuals use e-cigarettes at lower rates. Copyright © 2016 Elsevier Ltd.

    Prenatal exposure to maternal cigarette smoking (PEMCS) is associated with a higher probability of substance use in adolescence. We explore if externalizing behavior mediates this relationship, while controlling for a number of potential covariates of this mediation process. We used data obtained in two geographically distinct community samples of adolescents. The first (cross-sectional) sample consisted of 996 adolescents (12-18 years of age) recruited from the Saguenay Youth Study (SYS) in Canada (47% with PEMCS). The second (longitudinal) sample consisted of 1141 adolescents (49% with PEMCS) from the Northern Finland Birth Cohort (NFBC1986). In both samples, externalizing behavior and substance use were assessed during adolescence. In the NFBC1986 cohort, externalizing behavior was also assessed in childhood. In both populations, PEMCS is associated with a higher likelihood of adolescent drug experimentation. In the NFBC1986 cohort, exposed (versus non-exposed) adolescents experiment with an extra 1.27 [B = 0.24, 95% confidence intervals (CI) = 0.15, 0.33 P < 0.001] drugs. In the SYS cohort, a clear protective effect of not being exposed is shown: non-exposed (versus exposed) adolescents are 1.5 times [B = -0.42, 95% CI = -0.75, -0.09, P = 0.013] less likely to take drugs. These associations between PEMCS and drug experimentation remain in the multivariate and mediational analyses. Prenatal exposure to maternal cigarette smoking appears to be associated with a higher probability of experimenting with drugs during adolescence, both directly and indirectly via externalizing behavior and the number of peers reported as using drugs. © 2014 Society for the Study of Addiction.

    Cigarette smoking and attention-deficit/hyperactivity disorder (ADHD) are highly comorbid. One explanation is that individuals with ADHD use cigarettes as "self-medication" to alleviate their attention problems. However, animal studies reported that exposure to nicotine during adolescence influences the developing brain and negatively affects attention. This is the first human study exploring the effects of smoking during adolescence on attention problems. Longitudinal data on smoking and attention problems were available for 1987 adult and 648 adolescent monozygotic twin pairs from the Netherlands Twin Register. Twin pairs were classified as concordant/discordant for smoking and compared on attention problems. Within adult discordant pairs, the difference in attention problems between the smoking and never-smoking twins was first assessed cross-sectionally. In longitudinal analyses, the increase in attention problems from adolescence, when neither twin smoked, to adulthood was compared within discordant pairs. In subgroups with longitudinal data from childhood and adolescence, changes in smoking concordance and subsequent changes in attention problems were explored. Adult twins who ever smoked reported significantly more attention problems than their never-smoking co-twin. Longitudinal analyses showed a larger increase in attention problems from adolescence to adulthood in smoking twins than their never-smoking co-twin (p < .05). In childhood and adolescence, smoking twins had more attention problems than their never-smoking co-twin, whereas scores were similar before smoking was initiated or after both twins started smoking (not significant in all groups). Results from this genetically informative study suggest smoking during adolescence leads to higher attention problem scores, lasting into adulthood. Copyright © 2015 Society of Biological Psychiatry.

    To assess the impact of the introduction of graphic health warning labels on cigarette packets on adolescents at different smoking uptake stages. School-based surveys conducted in the year prior to (2005) and approximately 6 months after (2006) the introduction of the graphic health warnings. The 2006 survey was conducted after a TV advertising campaign promoting two new health warnings. Secondary schools in greater metropolitan Melbourne, Australia. Students in year levels 8-12: 2432 students in 2005, and 2050 in 2006, participated. Smoking uptake stage, intention to smoke, reported exposure to cigarette packs, knowledge of health effects of smoking, cognitive processing of warning labels and perceptions of cigarette pack image. At baseline, 72% of students had seen cigarette packs in the previous 6 months, while at follow-up 77% had seen packs and 88% of these had seen the new warning labels. Cognitive processing of warning labels increased, with students more frequently reading, attending to, thinking and talking about warning labels at follow-up. Experimental and established smokers thought about quitting and forgoing cigarettes more at follow-up. At follow-up intention to smoke was lower among those students who had talked about the warning labels and had forgone cigarettes. Graphic warning labels on cigarette packs are noticed by the majority of adolescents, increase adolescents' cognitive processing of these messages and have the potential to lower smoking intentions. Our findings suggest that the introduction of graphic warning labels may help to reduce smoking among adolescents.

    The present study examined the influence of flavouring on the smoking and vaping behaviour of cigarette smokers asked to adopt e-cigarettes for a period of 6 weeks. Participants were 88 current male and female smokers with no intention to stop smoking, but who agreed to substitute e-cigarettes for their current cigarettes. On intake, participants were administered tests of taste and smell for e-cigarettes flavoured with tobacco, menthol, cherry and chocolate, and were given a refillable e-cigarette of their preferred flavour or a control flavour. Participants completed daily logs of cigarette and e-cigarette use and were followed each week. Analyses over days indicated that, during the 6-week e-cigarette period, cigarette smoking rates dropped from an average of about 16 to about 7 cigarettes/day. e-Cigarette flavour had a significant effect such that the largest drop in cigarette smoking occurred among those assigned menthol e-cigarettes, and the smallest drop in smoking occurred among those assigned chocolate and cherry flavours. e-Cigarette vaping rates also differed significantly by flavour assigned, with the highest vaping rates for tobacco- and cherry-flavoured e-cigarettes, and the lowest rates for those assigned to chocolate. The findings suggest that adoption of e-cigarettes in smokers may influence smoking rates and that e-cigarette flavourings can moderate this effect. e-Cigarette vaping rates are also influenced by flavourings. These findings may have implications for the utility of e-cigarettes as a nicotine replacement device and for the regulation of flavourings in e-cigarettes for harm reduction.

    The effects of marijuana smoke exposure on several measures of tobacco cigarette smoking behavior were examined. Eight healthy adult male volunteers, who smoked both tobacco and marijuana cigarettes, participated in residential studies, lasting 10 to 15 days, designed to measure the effects of marijuana smoke exposure on a range of behavioral variables. Tobacco cigarettes were available throughout the day (9:00 A.M. until midnight). Each day was divided into a private period (9:00 A.M. to 5:00 P.M.), during which subjects were socially isolated, and a social period (5:00 P.M. to midnight), during which subjects could interact. Under blind conditions, subjects smoked placebo and active marijuana cigarettes (0%, 1.3%, 2.3%, or 2.7% delta 9-tetrahydrocannabinol) four times daily (9:45 A.M., 1:30 P.M., 5:00 P.M. and 8:30 P.M.). Each subject was exposed to both placebo and one active dose over 2- to 5-consecutive-day intervals, and dose conditions (i.e., placebo or active) alternated throughout the study. Active marijuana smoking significantly decreased the number of daily tobacco smoking bouts, increased inter-bout intervals and decreased inter-puff intervals. Marijuana decreased the number of tobacco smoking bouts by delaying the initiation of tobacco cigarette smoking immediately after marijuana smoking, whereas decreases in inter-puff intervals were unrelated to the time of marijuana smoking. No consistent interactions between marijuana effects and social or private periods (i.e., time of day) were observed.

  1. Are adolescents attempting to buy cigarettes on the internet?

    OBJECTIVE— To assess the prevalence of, and demographic and smoking behaviour correlates of, attempting to purchase cigarettes via the internet among adolescent current smokers.
METHODS— A representative sample of 17 181 10th and 12th grade California students completed a written questionnaire on tobacco related attitudes and behaviour during the 1999-2000 school year. Logistic regression analyses were used to determine the variables associated with attempting to purchase cigarettes on the internet.
RESULTS—Among youth under 18 years of age who were current smokers (n = 1689), 2.2% (95% confidence interval 1.5% to 2.9%) reported attempting to purchase cigarettes on the internet. Attempted internet purchases were more likely among younger respondents, males, frequent smokers, and respondents reporting lower perceived availability of tobacco products from retail and social sources.
CONCLUSIONS—Few adolescent smokers in California surveyed during the 1999-2000 school year had attempted to obtain cigarettes from the internet. As internet access increases, future studies should examine whether internet cigarette vendors sell to minors and whether adolescents are purchasing cigarettes on the internet.

    Background Sexual minority youth are more likely to smoke cigarettes than heterosexuals but research into the determinants of these disparities is lacking. Purpose To examine whether exposure to structural stigma predicts cigarette smoking in sexual minority youth. Methods Prospective data from adolescents participating in the Growing Up Today Study (2000–2005). Results Among sexual minority youth, living in low structural stigma states (e.g., states with non-discrimination policies inclusive of sexual orientation) was associated with a lower risk of cigarette smoking after adjustment for individual-level risk factors (Relative Risk[RR]=0.97, 95% Confidence Interval[CI]: 0.96, 0.99, p=0.02). This association remained marginally significant after additional controls for potential state-level confounders (RR=0.97, 95% CI: 0.93, 1.00, p=0.06). In contrast, among heterosexual youth, structural stigma was not associated with past-year smoking rates, documenting specificity of these effects to sexual minority youth. Conclusions Structural stigma represents a potential risk factor for cigarette smoking among sexual minority adolescents. PMID:24136092

    To investigate whether parenting style is an independent risk factor of smoking initiation and experimentation among adolescents, and whether there is a relationship between parenting style and readiness to quit, or nicotine dependence among smokers. The 84-item Health and Smoking Questionnaire, which assesses demographics, smoking status and smoking history, perceptions of risk and risk reduction, risk factors for tobacco use, and parenting style, was administered to 816 adolescents in grades 7 to 12 (mean age, 15.1 years) of whom 22.6% (n = 182) were smokers. Parenting style was measured by the brief, non-retrospective version of the Family of Origin Scale (FOS). Higher scores on the FOS indicated more positive perceived parenting style with high levels of intimacy and autonomy, characteristics of healthy parent-child relationships. Data were analyzed using a model-building approach to logistic regression with demographic and other psychosocial variables in the first two steps, and with parenting style as the last step. Results from two logistic regression models indicate that although parenting style is not a significant risk factor for smoking experimentation [odds ratio (OR) =.998; confidence interval (CI) =.977-1.019; p =.820], it is a significant independent risk factor for smoking initiation (OR =.950; CI =.930-.970; p =.000). Smokers who were more ready to quit had higher parenting style scores than those who were not ready to quit, and smokers who had made a serious quit attempt (an indicator of nicotine addiction) had higher parenting style scores than those who had not made a quit attempt. Moreover, nonsmokers who reported they would smoke a cigarette if their best friend offered had significantly lower parenting style scores than those who reported they would not smoke a cigarette. Additional research on parenting style and its impact on adolescent smoking with a more economically and ethnically diverse sample is warranted. If future research confirms

    Electronic cigarettes (e-cigarettes) are gaining in popularity among youth. While these products may be beneficial in adult smokers, the effect on young users of electronic and tobacco cigarettes (dual users) is unknown. The objective of this study was to assess the frequency of dual use among adolescents and to compare tobacco cigarette consumption among dual and exclusive tobacco cigarette users. A cross-sectional survey of a sample of 2213 Polish students aged 16-18 conducted between December 2013 and February 2014. Overall, 21.8 % of students were dual users. Dual users were more likely to smoke tobacco cigarettes on a daily basis [adjusted odds ratio, AOR 3.54 (95 % CI 2.34-5.36) and less likely to smoke fewer cigarettes per day (AOR 0.27 (95 % CI 0.12-0.57)] than exclusive tobacco cigarette users. The frequency of dual use was higher than exclusive use of a single product among Polish adolescents. Young dual users do not smoke a lower number of tobacco cigarettes per day than exclusive tobacco cigarette users.

    Comprehensive tobacco advertising/promotion bans are effective against adolescent smoking but many developing countries have implemented only partial bans. This study examines the association between advertising/promotions exposure and adolescent cigarette smoking risk in North Africa, and possible mediation of this association by parent and peer smoking. Adolescent data (n=12 329) from the Global Youth Tobacco Survey were analyzed (Libya, 2007; Egypt, 2005; Morocco, 2006; Tunisia 2007; and Sudan, 2005). Current smoking (any cigarette use in the past 30 days) and never-smokers' initiation susceptibility (composite of openness to accepting a cigarette from a friend and intention to start smoking in the next year) outcomes were examined. Advertising/promotion exposures included media and in-person contacts. Weighted univariate, bivariate and multivariable analyses were conducted. Current smoking prevalence ranged from 5.6% (Egypt) to 15.3% (Tunisia) among boys, and 1.1% (Libya and Egypt) to 2.0% (Morocco and Sudan) among girls. Initiation susceptibility ranged from 14.1% (Sudan) to 25.0% (Tunisia) among boys, and from 13.3% (Sudan) to 15.0% (Libya) among girls. Ninety-eight percent of adolescents reported exposure to at least one type of advertising/promotion. In multivariable analyses adjusting for demographics, each type of advertising/promotion was significantly and positively associated with boys' current smoking status; most advertising/promotion exposure types were also positively associated with initiation susceptibility among boys and girls. Peer smoking only partially mediated these associations. Tobacco advertising/promotion exposure was highly prevalent and associated with adolescents' smoking risk in these countries. The comprehensiveness and enforcement of advertising/promotion bans needs to be enhanced.

    This study extends research on receptivity to tobacco marketing over a key developmental period for cigarette smoking experimentation. The purpose of this study was to understand the effect of receptivity to tobacco marketing and exposure to friends who smoke on smoking experimentation. Participants were 10 to 13 years old who had never tried cigarettes (n = 878), interviewed six times at 8-month intervals. At baseline, 25% percent of the 10 and 11 years old in the sample of never smokers were receptive to tobacco marketing, while less than 5% had friends who smoked. Having a friend who smoked at study baseline and acquiring such friends for the first time during the study were the strongest predictors of smoking experimentation. Initial receptivity to tobacco marketing increased the risk of smoking experimentation independently of having friends who smoke at baseline or acquiring friends who smoke throughout the study period. The high level of receptivity observed even among 10 and 11 years old and its robust relationship with cigarette smoking experimentation independent of the significant risk associated with having friends who smoke suggests that successful prevention of receptivity may require intervention at an early age.

  8. Cigarette smoking: health effects and control strategies.

    Alberg, Anthony J

    2008-12-01

    Active cigarette smoking causes a broad spectrum of diseases that extend to many different organ systems. Its numerous deleterious health effects, combined with the substantial prevalence of cigarette smoking, make it a major worldwide cause of death. Smoking contributes so heavily to the mortality burden because it is a major cause of vascular disease, cancer and chronic obstructive pulmonary disease. In addition to these diseases, cigarette smoking also causes other respiratory symptoms, adversely affects reproductive outcomes and is a cause of diminished health status. Furthermore, exposure to secondhand smoke is an established cause of coronary heart disease and lung cancer, as well as a host of other adverse health effects. Given that cigarette smoking is such a major threat to global public health, controlling the worldwide epidemic of cigarette smoking would lead to enormous public health benefits. Strategies to control cigarette smoking at the societal level include smoke-free workplace legislation, increasing cigarette taxes and regulating cigarette advertising. On the individual level, preventing the initiation of cigarette smoking among youths is the optimal strategy; in practice, discovering efficacious primary prevention interventions has proven challenging. During the past two decades, major advances have been made in extending the menu of options available to assist dependent smokers in successfully quitting smoking. Successfully combating cigarette smoking requires a broad-based commitment to smoking control from multiple stakeholders, along with a multifaceted strategy that addresses both societal and individual factors.

    Background Adolescence is a critical developmental period when tobacco use is initiated and progression to regular smoking occurs. Another growing concern is the mounting evidence of ethnic/racial disparities in the smoking rates and adverse health consequences related to smoking. To reduce ethnic/racial disparities in smoking behaviors, understanding the protective influences against smoking behaviors among minority adolescents is important. Therefore, we examined the role of ethnic pride and parental disapproval of smoking on a wide range of smoking behaviors in ethnic/racial minority and White adolescents attending a suburban high school in Connecticut. Methods A total of 870 adolescents (ethnic/racial minority: n = 202) completed questions on susceptibility to smoking, ever trying a cigarette, smoking at least 1 cigarette daily in the past 30 days, as well as parental disapproval of smoking and ethnic pride in a school-wide survey. Results Logistic regression analyses indicated that perceived parental disapproval of adolescent smoking and ethnic pride were associated with susceptibility to smoking, ever trying a cigarette, and daily smoking differently for minority and White adolescents. For White youth, high parental disapproval of smoking was protective against all three smoking behaviors while ethnic pride was not. For minority youth, the combined protective effect of higher ethnic pride and higher parental disapproval of smoking was protective against all smoking behaviors. Conclusion The protective role of parental disapproval of smoking and ethnic pride on smoking behaviors may inform culturally sensitive smoking interventions aimed at diverse, multi-ethnic youth, and future studies are needed to examine this.

    The aim of this study was to examine whether smoking in movies can predict established smoking in adolescence. A longitudinal study was conducted over a period of 13 months with 4112 German students. Adolescents' exposure to smoking in movies was assessed by asking each student to indicate which film he or she had seen from a unique list of 50 movies, which was randomly selected for each individual survey from a sample of 398 popular contemporary movies. We calculated exposure to movie smoking for each respondent by summing the number of smoking occurrences for each movie that the respondent reported seeing. At follow-up, a total of 272 young people had smoked more than 100 cigarettes during their lifetime. While 2.1% of the young people with the lowest exposure to movie smoking initiated established smoking, 13.4% of the group with the highest exposure to movie smoking initiated established smoking. The adjusted relative risk of initiation of established smoking was 2.05 times higher in the group with the highest movie smoking exposure compared to the group with the lowest exposure (95% confidence interval: 1.25-3.35). Our data indicate that smoking in movies can be regarded as an independent risk factor for the initiation of established smoking in adolescence. © Georg Thieme Verlag KG Stuttgart · New York.

    E-cigarette use has dramatically increased. While studies have examined adolescents’ attitudes towards smoking, few have extended this research to adolescents’ attitudes towards e-cigarettes. The goal of this study was to examine adolescents' attitudes regarding e-cigarette ingredients, safety, addictive properties, social norms, accessibility, price, and regulation; and determine whether attitudes differ by past cigarette/e-cigarette use. Participants were 786 9th and 12th graders from California (63.21% females; mean age = 16.10 years [SD = 1.6]; 26.61% White, 21.98% Asian/Pacific Islander, 29.82% Hispanic, and 21.59% other). Results indicated that 19.05% of participants believed smoke from e-cigarettes is water; 23.03% believed e-cigarettes aren't a tobacco product; 40.36% considered e-cigarettes to be for cessation, and 43.13% felt they were safer than cigarettes. Participants felt it was more acceptable to use e-cigarettes indoors and outdoors compared to cigarettes (p < .0001), 23.13% felt raising e-cigarette taxes is a bad idea, 63.95% thought e-cigarettes were easier to get than cigarettes, 54.42% felt e-cigarettes cost too much, 64.33% felt the age for buying e-cigarettes should be raised, and 64.37% favored e-cigarette regulation. Adolescents who used e-cigarettes and/or cigarettes had significantly more favorable e-cigarette attitudes than non-users. This study indicates that adolescents are aware of some of the risks of e-cigarettes, although many harbor misperceptions and hold more favorable attitudes towards e-cigarettes than cigarettes. Of concern is the relationship between favorable e-cigarette attitudes and use. Findings suggest the need to provide adolescents with correct information about e-cigarette ingredients, risks, and the insufficient evidence of their role in cigarette cessation. PMID:27773711

    To review data demonstrating effective smoking cessation with electronic cigarettes (e-cigarettes). A literature search of MEDLINE/PubMed (1946-March 2014) was performed using the search terms e-cigarettes, electronic cigarettes, and smoking cessation. Additional references were identified from a review of literature citations. All English-language clinical studies assessing efficacy of e-cigarettes compared with baseline, placebo, or other pharmacological methods to aid in withdrawal symptoms, smoking reduction, or cessation were evaluated. A total of 6 clinical studies were included in the review. In small studies, e-cigarettes significantly decreased desire to smoke, number of cigarettes smoked per day, and exhaled carbon monoxide levels. Symptoms of nicotine withdrawal and adverse effects were variable. The most common adverse effects were nausea, headache, cough, and mouth/throat irritation. Compared with nicotine patches, e-cigarettes were associated with fewer adverse effects and higher adherence. Most studies showed a significant decrease in cigarette use acutely; however, long-term cessation was not sustained at 6 months. There is limited evidence for the effectiveness of e-cigarettes in smoking cessation; however, there may be a place in therapy to help modify smoking habits or reduce the number of cigarettes smoked. Studies available provided different administration patterns such as use while smoking, instead of smoking, or as needed. Short-term studies reviewed were small and did not necessarily evaluate cessation with a focus on parameters associated with cessation withdrawal symptoms. Though long-term safety is unknown, concerns regarding increased poisoning exposures among adults in comparison with cigarettes are alarming. © The Author(s) 2014.

  13. Peers and adolescent smoking.

    2003-05-01

    There is a considerable body of empirical research that has identified adolescent peer relationships as a primary factor involved in adolescent cigarette smoking. Despite this large research base, many questions remain unanswered about the mechanisms by which peers affect youths' smoking behavior. Understanding these processes of influence is key to the development of prevention and intervention programs designed to address adolescent smoking as a significant public health concern. In this paper, theoretical frameworks and empirical findings are reviewed critically which inform the current state of knowledge regarding peer influences on teenage smoking. Specifically, social learning theory, primary socialization theory, social identity theory and social network theory are discussed. Empirical findings regarding peer influence and selection, as well as multiple reference points in adolescent friendships, including best friendships, romantic relationships, peer groups and social crowds, are also reviewed. Review of this work reveals the contribution that peers have in adolescents' use of tobacco, in some cases promoting use, and in other cases deterring it. This review also suggests that peer influences on smoking are more subtle than commonly thought and need to be examined more carefully, including consideration of larger social contexts, e.g. the family, neighborhood, and media. Recommendations for future investigations are made, as well as suggestions for specific methodological approaches that offer promise for advancing our knowledge of the contribution of peers on adolescent tobacco use.

    The purpose was to examine cigarette smoking, use of snus, alcohol, and performance-enhancing illicit drugs among adolescent elite athletes and controls, and possible gender and sport group differences. First-year students at 16 Norwegian Elite Sport High Schools (n = 677) and two randomly selected high schools (controls, n = 421) were invited to participate. Totally, 602 athletes (89%) and 354 (84%) controls completed the questionnaire. More controls than athletes were smoking, using snus, and drinking alcohol. Competing in team sports was associated with use of snus [odds ratio = 2.8, 95% confidence interval (CI) 1.6 to 4.7] and a similar percentage of male and female handball (22.2% vs 18.8%) and soccer players (15.7% vs 15.0%) reported using snus. For controls, not participating in organized sport was a predictor for smoking (odds ratio = 4.9, 95% CI 2.2 to 10.9). Female athletes were more prone to drink alcohol than males (46.3% vs 31.0%, P < 0.001). Only, 1.2% athletes and 2.8% controls reported use of performance-enhancing illicit drugs. In conclusion, use of legal drugs is less common among athletes, but this relationship depends on type of sport and competition level. The association between team sports and use of snus suggests that sport subcultures play a role. © 2012 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Objectives Evaluate trends from 2011–2015 in electronic cigarette (e-cigarette) use among U.S. adolescents, grades 6–12, including prevalence and associations with past month use of cigarettes and other tobacco products, cigarette smoking intensity, quit attempts, and quit contemplation. Methods Five consecutive waves from the National Youth Tobacco Survey (N = 101,011) were used to estimate the grade- and race/ethnicity-standardized prevalence of past month use of e-cigarettes and nine non e-cigarette tobacco products. We assessed linear trends by year and compared outcomes (e.g., tobacco use, smoking intensity) by e-cigarette past month use. Results Past month e-cigarette use rose sharply from 2011–2015. In all years and both sexes, e-cigarette past month use and ever use were positively associated with use of cigarettes and other tobacco products, with past month e-cigarette use reaching 52% in 2015 among individuals who used ≥1 non e-cigarette tobacco product in the past month. Meanwhile, from 2011–2015, the population of adolescent past month e-cigarette users increasingly encompassed adolescents who were not past month users of other products (females: 19.0% to 41.7%; males: 11.1% to 36.7%) or had never used other products (females: 7.1% to 13.5%; males: 6.7% to 15.0%). Among male (but not female) past month cigarette users, there was a statistically significant positive association between past month e-cigarette use and daily cigarette smoking but not in all individual years. Past month e-cigarette use among past month cigarette smokers was not associated with cigarette quit attempts or quit contemplation, with no temporal trend. Conclusion Adolescent past month e-cigarette use is associated with past month use of other tobacco but not with cigarette quit attempts or quit contemplation among cigarette users. Over five years, the average characteristics of U.S. adolescents who use e-cigarettes have shifted, increasingly including more adolescents

    This experiment tested whether changing the location or visibility of the tobacco power wall in a life sized replica of a convenience store had any effect on adolescents' susceptibility to future cigarette smoking. The study was conducted in the RAND StoreLab (RSL), a life sized replica of a convenience store that was developed to experimentally evaluate how changing aspects of tobacco advertising displays in retail point-of-sale environments influences tobacco use risk and behaviour. A randomised, between-subjects experimental design with three conditions that varied the location or visibility of the tobacco power wall within the RSL was used. The conditions were: cashier (the tobacco power wall was located in its typical position behind the cash register counter); sidewall (the tobacco power wall was located on a sidewall away from the cash register); or hidden (the tobacco power wall was located behind the cashier but was hidden behind an opaque wall). The sample included 241 adolescents. Hiding the tobacco power wall significantly reduced adolescents' susceptibility to future cigarette smoking compared to leaving it exposed (ie, the cashier condition; p=0.02). Locating the tobacco power wall on a sidewall away from the cashier had no effect on future cigarette smoking susceptibility compared to the cashier condition (p=0.80). Hiding the tobacco power wall at retail point-of-sale locations is a strong regulatory option for reducing the impact of the retail environment on cigarette smoking risk in adolescents.

    Around 10% of adolescent students under 18 years have current asthma. Asthmatic adolescents smoke as much or more than non-asthmatic adolescents. We explored the association between exposure to mass media and social networks' influence with asthmatic student smoking, and variations of these exposures by sex. This study included 9755 asthmatic and 38,487 non-asthmatic middle and high school students. Secondary data analysis incorporated the complex sample design; and univariate, bivariate, and logistic regression statistics. Asthmatic students had greater odds of smoking than non-asthmatic students. Asthmatic female students were more likely than asthmatic male students to have been exposed to secondhand smoke in rooms or cars and to smoking actors, but less likely to associate smoking with intent to wear tobacco-marketing products, or with looking cool/fitting in. Asthmatic male and female students, who have smoking friends, were exposed to secondhand smoke in rooms (only girls) or cars, intended to smoke if best friends offered cigarettes, or received/bought tobacco marketing products had greater odds of smoking than other asthmatic students. The observed associations suggest the need for general interventions to reduce middle and high school students' cigarette smoking as well as targeted interventions for asthmatic adolescent students. © 2015, American School Health Association.

    Background This pilot study conducted a preliminary examination of whether Cognitive Bias Modification (CBM), a computerized task to retrain cognitive-approach biases towards smoking stimuli, (1) changed approach bias for cigarettes, and (2) improved smoking cessation outcomes in adolescent smokers. Methods Sixty adolescent smokers received four weeks of Cognitive Behavioral Therapy (CBT) for smoking cessation, with CBM (90% avoidance/10% approach for smoking stimuli and 10% avoidance/90% approach for neutral stimuli) or sham (50% avoidance/50% approach for smoking and neutral stimuli) training in the Netherlands (n = 42) and the United States (n = 18). Results While we did not observe changes in action tendencies related to CBM, adolescents with higher smoking approach biases at baseline had greater decreases in approach biases at follow up, compared to adolescents with smoking avoidance biases, regardless of treatment condition (p = 0.01). Intent-to-treat (ITT) analyses showed that CBM, when compared with sham trended toward higher end-of-treatment, biochemically-confirmed, seven-day point prevalence abstinence, (17.2% vs. 3.2%, p = 0.071). ITT analysis also showed that regardless of treatment condition, cotinine level (p = 0.045) and average number of cigarette smoked (p ≤ 0.001) significantly decreased over the course of treatment. Conclusions The findings from this pilot study suggests that re-training approach biases toward cigarettes shows promise for smoking cessation among adolescent smokers. Future research should utilize larger samples and increased distinction between CBM and sham conditions, and examine mechanisms underlying the CBM approach. PMID:26186485

    The primary purpose of this paper is to examine youth addiction and other justifications for adolescent smoking, and how they affect the level of consumption. Data from the Spanish 'State Survey on Drug Use among High School Students' aged between 14 and 18 years old were used in this paper. To account for the nature of the cigarette consumption data, several count data models were estimated in order to select the one that best fits adolescent smoking consumption. Most adolescent smokers smoke because it relaxes them, and about a quarter of them recognize that they are addicted. Moreover, the latter group smoke 44% more cigarettes than the rest (IRR = 1.444), revealing the strong addictive nature of tobacco, even at early ages. Moreover, parents' smoking increases the probability of smoking and has an impact on the level of consumption. The implications of these findings offer insight for parents, researchers, educators, and cessation interventionists, as awareness of self-reported and other predictors held by smoking youth creates a vantage point to facilitate changes in smoking behavior.

    To examine the relationship of objective smoking status to age, sex, longterm metabolic control, and urinary albumin excretion. Patients with type 1 diabetes who smoke are at increased risk to develop diabetic microvascular and macrovascular complications. While this has repeatedly been demonstrated in adults, smoking habits have rarely been investigated in adolescents. Urinary continine excretion has been determined by radioimmunoassay in 238 adolescents and young adults with type 1 diabetes. This biochemical parameter of nicotine use was related to age, to the number of cigarettes allegedly consumed per day, and to urinary albumin excretion. A total of 46 patients (19.3%) with urinary cotinine values > 500 ng/ml were classified as smokers. In 26 patients (10.9%), cotinine values between 100 and 500 ng/ml were found (infrequent smokers or environmental nicotine exposure), while the remaining 166 patients excreted < 100 ng/ml of cotinine in the urine (nonsmokers). Smokers were significantly older (20.2 +/- 0.6 years [mean +/- SE]) compared with the intermediate group (18.3 +/- 0.7 years) or with nonsmokers (15.9 +/- 0.4 years; P < 0.0001, Wilcoxon's signed-rank test). Of 46 smokers, 12 denied smoking cigarettes entirely, and among biochemically defined smokers, no correlation was present between urinary continine excretion and the reported number of cigarettes consumed per day. Urinary albumin excretion was significantly higher in smokers compared with nonsmokers (P < 0.003). These data demonstrate that cigarette smoking is common among German adolescents and young adults with type 1 diabetes in this study. Many patients deny nicotine use or refuse to disclose their smoking habits. Increased urinary albumin excretion is consistent with an increased risk of nephropathy in subjects with diabetes who smoke. Pediatricians in charge of adolescents with type 1 diabetes should actively discuss the risk of nicotine consumption with their patients.

    Given that many adolescent e-cigarette users are never-smokers, the possibility that e-cigarettes may act as a gateway to future cigarette smoking has been discussed in various studies. Longitudinal data are needed to explore the pathway between e-cigarette and cigarette use, particularly among different risk groups including susceptible and non-susceptible never-smokers. The objective of this study was to examine whether baseline use of e-cigarettes among a sample of never-smoking youth predicted cigarette smoking initiation over a 2-year period. Longitudinal cohort study. 89 high schools across Ontario and Alberta, Canada. A sample of grade 9-11 never-smoking students at baseline (n=9501) who participated in the COMPASS study over 2 years. Participants completed in-class questionnaires that assessed smoking susceptibility and smoking initiation. Among the baseline sample of non-susceptible never-smokers, 45.2% of current e-cigarette users reported trying a cigarette after 2 years compared with 13.5% of non-current e-cigarette users. Among the baseline sample of susceptible never-smokers, 62.4% of current e-cigarette users reported trying a cigarette after 2 years compared with 36.1% of non-current e-cigarette users. Overall, current e-cigarette users were more likely to try a cigarette 2 years later. This association was stronger among the sample of non-susceptible never-smokers (AOR=5.28, 95% CI 2.81 to 9.94; p<0.0001) compared with susceptible never-smokers (AOR=2.78, 95% CI 1.84 to 4.20; p<0.0001). Findings from this large, longitudinal study support public health concerns that e-cigarette use may contribute to the development of a new population of cigarette smokers. They also support the notion that e-cigarettes are expanding the tobacco market by attracting low-risk youth who would otherwise be unlikely to initiate using cigarettes. Careful consideration will be needed in developing an appropriate regulatory framework that prevents e-cigarette use

    Adolescents in foster care are at high risk for cigarette smoking. However, it is not clear how their smoking behaviors vary by gender. The present study examined lifetime and current smoking among males and females, and explored gender-specific risk factors for engagement in smoking behaviors. Data from the Multi Site Evaluation of Foster Youth Programs was used to evaluate patterns of smoking among adolescents aged 12-18 years (N = 1121; 489 males, 632 females). Males and females did not differ significantly in rates of lifetime and current smoking, or in the age of smoking initiation and number of cigarettes smoked on a typical day. Gender-based analyses revealed that older age and placement in group homes or residential treatment facilities were associated with heightened risk of smoking among males. In contrast, sexual minority status (i.e., nonheterosexual orientation) and increased childhood victimization were associated with heightened risk of smoking among females. A history of running away was linked to smoking in both genders. Gender should be considered when designing intervention programs to address cigarette smoking among foster youth, as the stressors associated with smoking may differ for males and females.

    American Indians have the highest smoking rate of all major racial/ethnic groups in the US, despite significant variation across tribes and regions of the country. Yet, little research has been conducted on smoking initiation among American Indian adolescents. In an effort to identify the mechanisms through which families influence teen smoking, both positively and negatively, 20 focus groups were conducted with 144 non-reservation American Indian teens in Oklahoma. Findings indicated that most of the antismoking messages from family members were given by parents and grandparents, and focused on the long-term health consequences of smoking and addiction. Parental responses to teen smoking varied widely, with some responses sending mixed messages to the teens. Many teens discussed obtaining their first cigarette in a family setting and the teens felt that having smokers in their families influenced them to try smoking. Teens were able to discuss the traditional role of tobacco in their culture and were aware of its presence at Indian events, but felt ceremonial and traditional use was distinct from recreational use. Additional research is necessary to assess whether these results are generalizable to other tribes and regions, and to other racial/ethnic groups.

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

    Although previous studies indicate that people with lower intelligence quotient (IQ) scores are more likely to become cigarette smokers, IQ scores of siblings discordant for smoking and of adolescents who began smoking between ages 18-21 years have not been studied systematically. Each year a random sample of Israeli military recruits complete a smoking questionnaire. Cognitive functioning is assessed by the military using standardized tests equivalent to IQ. Of 20 221 18-year-old males, 28.5% reported smoking at least one cigarette a day (smokers). An unadjusted comparison found that smokers scored 0.41 effect sizes (ES, P < 0.001) lower than non-smokers; adjusted analyses remained significant (adjusted ES = 0.27, P < 0.001). Adolescents smoking one to five, six to 10, 11-20 and 21+ cigarettes/day had cognitive test scores 0.14, 0.22, 0.33 and 0.5 adjusted ES poorer than those of non-smokers (P < 0.001). Adolescents who did not smoke by age 18, and then began to smoke between ages 18-21 had lower cognitive test scores compared to never-smokers (adjusted ES = 0.14, P < 0.001). An analysis of brothers discordant for smoking found that smoking brothers had lower cognitive scores than non-smoking brothers (adjusted ES = 0.27; P = 0.014). Controlled analyses from this large population-based cohort of male adolescents indicate that IQ scores are lower in male adolescents who smoke compared to non-smokers and in brothers who smoke compared to their non-smoking brothers. The IQs of adolescents who began smoking between ages 18-21 are lower than those of non-smokers. Adolescents with poorer IQ scores might be targeted for programmes designed to prevent smoking.

    To assess the effect that cigarette legislation would have on reducing merchant sales rates of cigarettes to minors and the affect on adolescent smoking behavior. Observational survey of merchant selling behaviors and adolescent smoking habits before and after passage of legislation. The setting for the merchant survey was Woodridge, Ill (population 25,200), a suburban community of Chicago. The surveys were distributed to adolescents in the local junior high school. Convenience sample of both merchants and adolescent students. Passage of community antismoking legislation. Percentage of stores selling cigarettes to minors in Woodridge and percentage of students who had experimented with cigarettes or were regular smokers. Merchant sales rates in Woodridge decreased from a baseline of 70% before legislation to less than 5% in 1.5 years of compliance checking after legislation. Student surveys showed that the rates of cigarette experimentation and regular use of cigarettes by adolescents were reduced by over 50%. Cigarette control laws can be effective in significantly reducing the rate of cigarettes sold by merchants and rates of cigarette use by adolescents. Key elements of successful legislation implementation are consistent compliance checking and heightened community awareness of the problems and prevalence of adolescent smoking.

    To assess the impact of tobacco control policies relating to youth access, clean indoor air and tobacco advertising at point-of-sale and outdoors, in addition to cigarette price and per capita tobacco control spending, on adolescent smoking prevalence. Repeated cross-sectional surveys. Logistic regression analyses examined association between policies and smoking prevalence. Australia, 1990-2005. A nationally representative sample of secondary students (aged 12-17 years) participating in a triennial survey (sample size per survey range: 20 560 to 27 480). Students' report of past-month smoking. In each jurisdiction, extent of implementation of the three policies for the year of the survey was determined. For each survey year, national per capita tobacco control spending was determined and jurisdiction-specific 12-month change in cigarette price obtained. Extent of implementation of the three policy areas varied between states and over the survey years. Multivariate analyses that adjusted for demographic factors, year and all tobacco control variables showed that 12-month cigarette price increases [odds ratio (OR): 0.98, 95% confidence interval (CI): 0.97-0.99], greater per capita tobacco control spending (OR: 0.99, 95% CI: 0.98-0.99) and stronger implementation of clean indoor air policies (OR: 0.93, 95% CI: 0.92-0.94) were associated with reduced smoking prevalence. Adult-directed, population-based tobacco control policies such as clean indoor air laws and increased prices of cigarettes, implemented as part of a well-funded comprehensive tobacco control programme are associated with lower adolescent smoking. © 2011 The Authors, Addiction © 2011 Society for the Study of Addiction.

    This study addresses the dearth of population-based research on how comprehensive household smoke-free rules (ie, in the home and car) relate to tobacco use and secondhand smoke (SHS) exposure among adolescents. Analysis of 2014 Minnesota Youth Tobacco Survey. Representative sample of Minnesota youth. A total of 1287 youth who lived with a smoker. Measures included household smoke-free rules (no rules, partial rules-home or car, but not both-and comprehensive rules), lifetime and 30-day cigarette use, 30-day cigarette and other product use, and SHS exposure in past 7 days in home and car. Weighted multivariate logistic, zero-inflated Poisson, and zero-inflated negative binomial regressions were used. Compared to comprehensive rules, partial and no smoke-free rules were significantly and positively related to lifetime cigarette use (respectively, adjusted odds ratio [AOR] = 1.80, 95% confidence interval [CI] = 1.24-2.61; AOR = 2.87, 95% CI = 1.93-4.25), and a similar significant pattern was found for 30-day cigarette use (respectively, AOR = 2.20, 95% CI = 1.21-4.02; AOR = 2.45, 95% CI = 1.34-4.50). No smoke-free rules significantly predicted using cigarettes and other tobacco products compared to comprehensive rules. In both descriptive and regression analyses, we found SHS exposure rates in both the home and car were significantly lower among youth whose household implemented comprehensive smoke-free rules. Comprehensive smoke-free rules protect youth from the harms of caregiver tobacco use. Relative to both partial and no smoke-free rules, comprehensive smoke-free rules have a marked impact on tobacco use and SHS exposure among youth who live with a smoker. Health promotion efforts should promote comprehensive smoke-free rules among all households and particularly households with children and adolescents.

    Electronic cigarette (e-cigarette) use is increasing rapidly, and the impact on youth is unknown. We assessed associations between e-cigarette use and smoking intentions among US youth who had never smoked conventional cigarettes. We analyzed data from the nationally representative 2011, 2012, and 2013 National Youth Tobacco Surveys of students in grades 6-12. Youth reporting they would definitely not smoke in the next year or if offered a cigarette by a friend were defined as not having an intention to smoke; all others were classified as having positive intention to smoke conventional cigarettes. Demographics, pro-tobacco advertisement exposure, ever use of e-cigarettes, and ever use of other combustibles (cigars, hookah, bidis, kreteks, and pipes) and noncombustibles (chewing tobacco, snuff, dip, snus, and dissolvables) were included in multivariate analyses that assessed associations with smoking intentions among never-cigarette-smoking youth. Between 2011 and 2013, the number of never-smoking youth who used e-cigarettes increased 3-fold, from 79,000 to more than 263,000. Intention to smoke conventional cigarettes was 43.9% among ever e-cigarette users and 21.5% among never users. Ever e-cigarette users had higher adjusted odds for having smoking intentions than never users (adjusted odds ratio = 1.70, 95% confidence interval = 1.24-2.32). Those who ever used other combustibles, ever used noncombustibles, or reported pro-tobacco advertisement exposure also had increased odds for smoking intentions. In 2013, more than a quarter million never-smoking youth used e-cigarettes. E-cigarette use is associated with increased intentions to smoke cigarettes, and enhanced prevention efforts for youth are important for all forms of tobacco, including e-cigarettes.

    The present study was undertaken to test the hypothesis that smoking induces peripheral endothelial dysfunction and altered function in central conduit arteries. A total of 22 healthy volunteers (10 women and 12 men; mean age 25.3 +/- 5.8 years) were included. At baseline, brachial artery flowmediated dilatation (FMD), aortic stiffness index (ASI), aortic distensibility (AoD), and aortic elastic modulus (AoEM) of all subjects were measured. On the 2nd day, the subjects were assigned to smoke either 1 light (0.6 mg of nicotine, 8 mg of tar, and 9 mg of carbon monoxide) or 1 regular cigarette (0.9 mg of nicotine, 12 mg of tar, and 12 mg of carbon monoxide) and the measurements were repeated for all subjects 20 minutes following smoking. After 15 days, the subjects were assigned to smoke 1 cigarette of the type that was not smoked on the 2nd day, and the same measurements were performed 20 minutes after smoking. In response to smoking 1 light cigarette, FMD values declined from 15.0 +/- 6.8% to 9.1 +/- 2.9% (P = 0.002). After smoking 1 regular cigarette, FMD values declined from 15.0 +/- 6.8% to 9.4 +/- 4.8% (P= 0.002). Aortic elasticity and left ventricular diastolic functions (LVDF) were significantly impaired by both types of cigarettes. Smoking light cigarettes has similar acute detrimental effects on FMD, LVDF, ASI, AoD, and AoEM as regular cigarettes.

    Objective To examine mediators of the association between childhood attention-deficit/hyperactivity disorder (ADHD) and adolescent cigarette use. Method Participants were 142 adolescents diagnosed with ADHD in childhood and 100 adolescents without ADHD. Results Among probands, cigarette smoking was more frequent, adaptive coping skills (behavioral and cognitive) were fewer, and parental support was lower. Coping and support partially mediated the ADHD association with smoking. Persistence of ADHD and adolescent conduct disorder were also important. Conclusions Vulnerability to smoking among probands may be partly due to fewer problem-solving resources. Coping skill deficits and parent–child communication may be important treatment targets for smoking prevention. PMID:15863431

    Smoking media literacy (SML) has been found to be independently associated with reduced current smoking and reduced susceptibility to future smoking in a sample of American adolescents, but not in other populations of adolescents. Thus, the purpose of this study was to assess SML in Vietnamese adolescents and to determine the association with smoking behavior and susceptibility to future smoking. A cross-sectional survey of 2000 high school students completed the SML scale, which is based on an integrated theoretical framework of media literacy, and items assessing cigarette use. Ordinal logistic regression was used to determine the association of SML with smoking and susceptibility to future smoking. Ordinal logistic regression was also to determine whether smoking in the past 30 days was associated with the 8 domains/core concepts of media literacy which comprise the SML. Smoking media literacy was lower among the Vietnamese adolescents than what has been previously reported in American adolescents. Ordinal logistic regression analysis results showed that in the total sample SML was associated with reduced smoking, but there was no association with susceptibility to future smoking. Further analysis showed that results differed according to school and grade level. There did not appear to be association of smoking with the specific domains/concepts that comprise the SML. The association of SML with reduced smoking suggests the need for further research involving SML, including the testing of media literacy training interventions, in Vietnamese adolescents and also other populations of adolescents. © 2011, American School Health Association.

    There has been little research examining whether e-cigarette use increases the risk of cigarette initiation among adolescents in the transition to adulthood when the sale of cigarettes becomes legal. The Children's Health Study is a prospectively followed cohort in Southern California. Data on e-cigarette use were collected in 11th and 12th grade (mean age = 17.4); follow-up data on tobacco product use were collected an average of 16 months later from never-smoking e-cigarette users at initial evaluation (n = 146) and from a sample of never-smoking, never e-cigarette users (n = 152) frequency matched to e-cigarette users on gender, ethnicity, and grade. Cigarette initiation during follow-up was reported by 40.4% of e-cigarette users (n = 59) and 10.5% of never users (n = 16). E-cigarette users had 6.17 times (95% confidence interval: 3.30-11.6) the odds of initiating cigarettes as never e-cigarette users. Results were robust to adjustment for potential confounders and in analyses restricted to never users of any combustible tobacco product. Associations were stronger in adolescents with no intention of smoking at initial evaluation. E-cigarette users were also more likely to initiate use of any combustible product (odds ratio = 4.98; 95% confidence interval: 2.37-10.4), including hookah, cigars, or pipes. E-cigarette use in never-smoking youth may increase risk of subsequent initiation of cigarettes and other combustible products during the transition to adulthood when the purchase of tobacco products becomes legal. Stronger associations in participants with no intention of smoking suggests that e-cigarette use was not simply a marker for individuals who would have gone on to smoke regardless of e-cigarette use.

    The use of electronic cigarettes (e-cigarettes) is increasing, but their use as a smoking-cessation aid is controversial. The reporting of e-cigarette studies on cessation is variable and inconsistent. To date, only 1 randomized clinical trial has included an arm with other cessation methods (nicotine patches). The cessation rates for available clinical trials are difficult to compare given differing follow-up periods and broad ranges (4% at 12 months with non-nicotine e-cigarettes to 68% at 4 weeks with concomitant nicotine e-cigarettes and other cessation methods). The average combined abstinence rate for included prospective studies was 29.1% (combination of 6-18 months׳ rates). There are few comparable clinical trials and prospective studies related to e-cigarettes use for smoking cessation, despite an increasing number of citations. Larger randomized clinical trials are essential to determine whether e-cigarettes are effective smoking-cessation devices. Copyright © 2016 Southern Society for Clinical Investigation.

  18. Cigarette Filter Ventilation and Smoking Protocol Influence Aldehyde Smoke Yields

    2018-01-01

    The WHO study group on tobacco product regulation (TobReg) advised regulating and lowering toxicant levels in cigarette smoke. Aldehydes are one of the chemical classes on the TobReg smoke toxicants priority list. To provide insight in factors determining aldehyde yields, the levels of 12 aldehydes in mainstream cigarette smoke of 11 Dutch brands were quantified. Variations in smoking behavior and cigarette design affecting human exposure to aldehydes were studied by using four different machine testing protocols. Machine smoking was based on the International Standardization Organization (ISO) and Health Canada Intense (HCI) regime, both with and without taping the filter vents. The 11 cigarette brands differed in (i) design and blend characteristics; (ii) tar, nicotine, and carbon monoxide (TNCO) levels; (iii) popularity; and (iv) manufacturer. Cigarette smoke was trapped on a Cambridge filter pad and carboxen cartridge. After being dissolved in methanol/CS2 and derivatization with DNPH, the aldehyde yields were determined using HPLC-DAD. Using an intense smoking regime (increased puff volume, shorter puff interval) significantly increased aldehyde yields, following the pattern: ISO < ISO-taped < HCI-untaped < HCI. For all of the regimes, acetaldehyde and acrolein yields were strongly correlated (r = 0.804). The difference in TNCO and aldehyde levels between regular and highly ventilated low-TNCO cigarettes (as measured using ISO) diminished when smoking intensely; this effect is stronger when combined with taping filter vents. The highly ventilated low-TNCO brands showed six times more aldehyde production per mg nicotine for the intense smoking regimes. In conclusion, acetaldehyde and acrolein can be used as representatives for the class of volatile aldehydes for the different brands and smoking regimes.

    Adolescents' use of electronic cigarettes and shisha-tobacco increased in several countries during the 2000s, including in the United States, United Kingdom and Canada. Few studies have examined the factors associated with exclusive e-cigarette or shisha-tobacco use and whether adolescents using these substances exclusively differ from those using traditional cigarettes. To examine the socio-demographic and behavioural correlates of exclusive e-cigarette and exclusive shisha-tobacco use to those found for users of tobacco cigarettes and multiple nicotine products in Australian adolescents. Cross-sectional survey of smoking behaviours of a random sample of 4,576 students in the Australian state of Victoria aged 12-17 conducted between June 2014 and December 2014. Overall, 14% of students had used an e-cigarette with 3% using e-cigarettes exclusively. 13% had used shisha-tobacco, with 2% using shisha-tobacco exclusively. Most students (65%) using e-cigarette and shisha-tobacco (67%) had also used tobacco cigarettes. After adjusting for demographic factors, students using e-cigarettes only were more likely to have never used cannabis or drink alcohol in the past year compared to tobacco cigarette users. Compared to tobacco cigarette users, students using only shisha-tobacco were younger, less likely to use cannabis or alcohol or have friends or parents who smoke. Most Australian adolescents who use alternative nicotine and tobacco-related products do so in conjunction with tobacco cigarettes. Students using e-cigarettes or shisha-tobacco exclusively were less likely to use other substances. Australian longitudinal studies are needed to determine whether this group of students are on a pathway to traditional tobacco use.

    E-cigarettes have been suggested as a strategy for reducing harm from cigarettes. Although e-cigarettes could be a less-harmful alternative to cigarettes for those trying to quit, there may also be costs that outweigh any benefits of reduction. The purpose of the present study was to prospectively investigate perceptions of e-cigarettes, cigarette smoking intentions, and their associations with e-cigarette use over time. Community participants (N = 348, 57% male) aged 18 to 24 years were recruited for a longitudinal study of tobacco use. Inclusion criteria included nondaily cigarette smoking for ≥ 6 months with no history of daily smoking. Participants reported e-cigarette use over the past 14 days at baseline, and for the past 9 days at 3, 6, and 9 months. Assessments were completed online or via mobile phone. Across the 4 assessments, 22% to 33% of participants reported recent e-cigarette use. Intent to quit smoking cigarettes and intent to maintain smoking were unrelated to e-cigarette frequency. E-cigarette frequency was positively associated with perceiving e-cigarettes as less harmful than cigarettes and more positive e-cigarette expectancies (ps < .05). E-cigarette use was also more frequent among those who smoked cigarettes frequently and who used e-cigarettes to circumvent cigarette bans more often (ps < .05). The combination of these findings suggests that, at least among nondaily smoking young adults, other factors may influence frequency of e-cigarette use more than harm reduction. Findings instead seem consistent with the hypothesis that e-cigarettes are more often used to complement ongoing cigarette smoking. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

    In the United States, cigarette use is the leading cause of preventable death, and most adult smokers started before the age of 18 years.

    10 habitual smokers, aged 19-25 yr., were randomly assigned to smoke either a very low nicotine "Placebo" cigarette (.05-mg nicotine delivery as estimated by the FTC method) or a Nicotine cigarette (.7-mg estimated nicotine delivery). Each participant was asked to abstain from smoking for 4 to 7 hr. prior to testing. After completing a presmoking test of lexical decision-making, participants smoked either a Nicotine or Placebo cigarette and were then retested for reaction times and accuracy on the lexical decision test. When presented the most difficult lexical decisions, participants responded significantly faster after smoking a Nicotine cigarette than they did before smoking; smoking a Placebo cigarette did not affect reaction times. Response accuracy was unaffected by smoking either kind of cigarette. These results suggest that smoking a nicotine cigarette may improve attention or memory retrieval after several hours of smoking abstinence.

  3. Cigarette Taxes, Smoking-and Exercise?

    PubMed

    This research provides the first in-depth analysis of the effect that increased cigarette taxes have on exercise behavior. Smoking may diminish the ability to exercise; individuals may also use exercise to compensate for the harmful health effects of smoking or to avoid gaining weight if they cut back. Our conceptual model highlights these and several other avenues for effect and reveals that the predicted effect of cigarette costs on exercise behavior is theoretically ambiguous. To investigate the relationship empirically, 1994-2012 data from the behavioral risk factor surveillance system are combined with state level cigarette tax rates and other state level variables. Several measures of both smoking and exercise behavior are created and estimated in reduced form models. Our results suggest that both smoking and exercise are reduced by cigarette taxes. However, the effects on exercise may be more complicated as we find that certain groups, such as young adults or those who have recently quit smoking, are affected differently. Our analyses also show that the responsiveness of both smoking and exercise behavior to cigarette costs is much smaller in the 2000s, an era of high-tax increases.

    Exposure to nicotine in electronic cigarettes (e-cigarettes) is becoming increasingly common among adolescents who report never having smoked combustible tobacco. To evaluate whether e-cigarette use among 14-year-old adolescents who have never tried combustible tobacco is associated with risk of initiating use of 3 combustible tobacco products (ie, cigarettes, cigars, and hookah). Longitudinal repeated assessment of a school-based cohort at baseline (fall 2013, 9th grade, mean age = 14.1 years) and at a 6-month follow-up (spring 2014, 9th grade) and a 12-month follow-up (fall 2014, 10th grade). Ten public high schools in Los Angeles, California, were recruited through convenience sampling. Participants were students who reported never using combustible tobacco at baseline and completed follow-up assessments at 6 or 12 months (N = 2530). At each time point, students completed self-report surveys during in-classroom data collections. Student self-report of whether he or she ever used e-cigarettes (yes or no) at baseline. Six- and 12-month follow-up reports on use of any of the following tobacco products within the prior 6 months: (1) any combustible tobacco product (yes or no); (2) combustible cigarettes (yes or no), (3) cigars (yes or no); (4) hookah (yes or no); and (5) number of combustible tobacco products (range: 0-3). Past 6-month use of any combustible tobacco product was more frequent in baseline e-cigarette ever users (n = 222) than never users (n = 2308) at the 6-month follow-up (30.7% vs 8.1%, respectively; difference between groups in prevalence rates, 22.7% [95% CI, 16.4%-28.9%]) and at the 12-month follow-up (25.2% vs 9.3%, respectively; difference between groups, 15.9% [95% CI, 10.0%-21.8%]). Baseline e-cigarette use was associated with greater likelihood of use of any combustible tobacco product averaged across the 2 follow-up periods in the unadjusted analyses (odds ratio [OR], 4.27 [95% CI, 3.19-5.71]) and in the analyses adjusted

    Cigarette pricing policy is one tool for controlling smoking behavior on a national scale. It is unclear, however, what effects such policy has on adolescents and which characteristic subgroups of adolescents are more or less sensitive to cigarette pricing policy. Our data came from the 2013 Korea Youth Risk Behavior Web-based Survey. The dependent variable was whether or not a participant was classified as a "persistent smokers," defined as a smoker who would continue smoking despite any price increase. Other variables of interest were smoking days (quantity), previous attempts to stop smoking, and previous education on smoking cessation. The statistical analysis was performed using weighted data and the SURVEYFREQ and SURVEYLOGISTIC procedures in SAS 9.3. Among 7094 adolescent smokers (5349 males and 1745 females), 19.9% of males and 25.1% of females reported as persistent smokers. Compared with light smokers, heavy smokers are more likely to be persistent smokers (male: odds ratio [OR] = 2.45, 95% confidence interval [CI] = 2.04-2.95, P value < .001; female: OR = 3.23, 95% CI = 2.44-4.27, P value < .001). When we stratified the data by household income, previous attempts to stop smoking, and previous education on smoking cessation, that trend remained statistically significant. Because heavier smokers with higher risk of health-related consequences were less sensitive to pricing policy than mild smokers, pricing policy alone is not enough to reduce the societal burden caused by smoking. We suggest that additional cessation policy is needed along with pricing policy for adolescents with heavier smoking behavior in Korea. This study shows that heavy smokers are more likely to be persistent smokers despite the cigarette price increase policy, compared with light smokers in Korean adolescents. Because heavier smokers were less sensitive to pricing policy than mild smokers, pricing policy alone is not enough to reduce the societal burden caused by smoking. We suggest

    Individuals with sleep complaints often exhibit unhealthy lifestyles, including obesity, excessive alcohol use, lack of physical exercise, and cigarette smoking. We sought to explore the relationship between cigarette smoking, poor sleep habits, and sleep complaints. Several lines of evidence suggest a relationship between cigarette smoking and sleep disturbance, including the effects of nicotine and nicotine withdrawal on sleep, a tendency for nonsmokers to be more alert in the morning, an association between cigarette smoking and snoring, and a tendency for individuals who engage in one unhealthy behavior also to engage in others. A total of 484 individuals aged 14 to 84 years completed a comprehensive sleep and health questionnaire. There were 99 high school students from grades 9 through 12 (45 boys and 54 girls, of whom 38 [38%] were smokers), who completed an in-class survey. In addition, 385 adults aged 20 to 84 years (122 men and 263 women, of whom 77 [20%] were smokers) from a random sample of 1000 completed a mail survey. The effects of age and smoking status on sleep, health, and daytime function were assessed by multivariate analysis of variance. Cigarette smokers were significantly more likely than nonsmokers to report problems going to sleep, problems staying asleep, daytime sleepiness, minor accidents, depression, and high daily caffeine intake. Individuals with sleep complaints should be queried about tobacco use. Those who are smokers should be advised that there is a relationship between cigarette smoking and sleep disturbance.

    High school students' electronic cigarette (e-cigarette) use rose rapidly in 2014, to levels higher than cigarette smoking, which declined significantly. This study assesses how frequency of e-cigarette use is associated with students' smoking status. Using Monitoring the Future data in 2015, this study evaluated the association between students' smoking and frequency of 30-day e-cigarette use in 2014, focusing on high school seniors. Previous research has considered only whether e-cigarettes were used at all during the past month. Non-smokers were far less likely than smokers to have used an e-cigarette (p<0.001). E-cigarette use frequency rose with the amount of ever smoking (p<0.001). However, among current smokers, there was no difference in e-cigarette use by very light smokers (<1 cigarette/day); light smokers (1-5 cigarettes/day); and heavy smokers (≥1/2 pack/day) (p=0.99). Because most students have never smoked, never smokers constituted 25% of all seniors who used an e-cigarette. Among tenth- and eighth-graders, 43% and 48% of past-month e-cigarette users had never smoked. Non-smoking high school students are highly unlikely to use e-cigarettes; among those who do, most used them only on 1-2 of the past 30 days. By contrast, current smokers are likely to use e-cigarettes and on many more days. It is unclear whether students' e-cigarette use represents short-term experimentation or future sustained use, and whether it will eventually increase or decrease youth smoking and nicotine addiction. More sophisticated research methods, employing better data, will be essential to unravel the mystery that is the e-cigarette phenomenon. Copyright © 2016 American Journal of Preventive Medicine.

  9. Reasons for quitting cigarette smoking and electronic cigarette use for cessation help.

    2015-03-01

    Despite the lack of clarity regarding their safety and efficacy as smoking cessation aids, electronic cigarettes (e-cigarettes) are commonly used to quit smoking. Currently, little is understood about why smokers may use e-cigarettes for help with smoking cessation compared with other, proven cessation aids. This study aimed to determine the reasons for wanting to quit cigarettes that are associated with the use of e-cigarettes for cessation help versus the use of conventional nicotine replacement therapy (NRT) products (e.g., gums). Cross-sectional, self-report data were obtained from 1,988 multiethnic current daily smokers (M age = 45.1, SD = 13.0; 51.3% women) who had made an average of 8.5 (SD = 18.7) lifetime quit attempts but were not currently engaged in a cessation attempt. Reasons for wanting to quit smoking were assessed by using the Reasons for Quitting scale. Path analyses suggested that among reasons for quitting cigarettes, "immediate reinforcement"-a measure of wanting to quit cigarettes for extrinsic reasons such as bad smell, costliness and untidiness-was significantly associated with having tried e-cigarettes for cessation help, and "concerns about health" was associated with having tried NRT-only use. E-cigarettes appear to provide an alternative "smoking" experience to individuals who wish to quit cigarette smoking because of the immediate, undesirable consequences of tobacco smoking (e.g., smell, ash, litter) rather than concerns about health. Provided that the safety of e-cigarette use is ensured, e-cigarettes may be effectively used to reduce tobacco exposure among smokers who may not want to quit cigarettes for intrinsic motivation.

    Introduction: Electronic cigarette (e-cigarette) use is increasing rapidly, and the impact on youth is unknown. We assessed associations between e-cigarette use and smoking intentions among US youth who had never smoked conventional cigarettes. Methods: We analyzed data from the nationally representative 2011, 2012, and 2013 National Youth Tobacco Surveys of students in grades 6–12. Youth reporting they would definitely not smoke in the next year or if offered a cigarette by a friend were defined as not having an intention to smoke; all others were classified as having positive intention to smoke conventional cigarettes. Demographics, pro-tobacco advertisement exposure, ever use of e-cigarettes, and ever use of other combustibles (cigars, hookah, bidis, kreteks, and pipes) and noncombustibles (chewing tobacco, snuff, dip, snus, and dissolvables) were included in multivariate analyses that assessed associations with smoking intentions among never-cigarette-smoking youth. Results: Between 2011 and 2013, the number of never-smoking youth who used e-cigarettes increased 3-fold, from 79,000 to more than 263,000. Intention to smoke conventional cigarettes was 43.9% among ever e-cigarette users and 21.5% among never users. Ever e-cigarette users had higher adjusted odds for having smoking intentions than never users (adjusted odds ratio = 1.70, 95% confidence interval = 1.24–2.32). Those who ever used other combustibles, ever used noncombustibles, or reported pro-tobacco advertisement exposure also had increased odds for smoking intentions. Conclusion: In 2013, more than a quarter million never-smoking youth used e-cigarettes. E-cigarette use is associated with increased intentions to smoke cigarettes, and enhanced prevention efforts for youth are important for all forms of tobacco, including e-cigarettes. PMID:25143298

    This study reports the prevalence of electronic cigarette (e-cigarette) use among adolescents in Greece and explores how dual smokers of e-cigarettes and combustible (conventional) cigarettes differ from smokers of only combustible cigarettes across socio-demographic, familial, psychosomatic health and substance use characteristics. Self-reports on smoking were collected from a nationally representative sample of 1320 15-year-old Greek students in the 2014 Health Behaviour in School-aged Children study. Bivariate and multivariable logistic regression analyses were carried out with dependent variables a) lifetime smoking conventional cigarettes and b) lifetime e-cigarette use among lifetime smokers. About 36.9% of 15-year-olds reported lifetime smoking of conventional cigarettes, and 16.6% lifetime use of e-cigarettes, mostly experimenting (0.5% reported current e-cigarette use). Six in 7 ever e-cigarette smokers had smoked conventional cigarettes. Peers who smoke and lifetime cannabis use were significant correlates of both lifetime conventional cigarette and e-cigarette smoking, but more strongly for smoking conventional cigarettes. Alcohol use and low parental monitoring correlated with tobacco smoking but not e-cigarette use. Girls were more likely than boys to report lifetime use of tobacco, but, among lifetime smokers, boys had almost seven times the odds of girls of e-cigarette use. In lifetime smokers, low life satisfaction in females and current smoking of conventional tobacco were independently associated with the experimentation with e-cigarettes. Experimental use of e-cigarettes is relatively widespread among adolescents in Greece. Targeted interventions should focus on male smokers and the role of peer processes and cannabis use in the risk of experimenting with e-cigarettes. Copyright © 2015 Elsevier Ltd.

Results If e-cigarettes increase individual-level smoking cessation probabilities by 20%, the model estimates a 6% reduction in smoking prevalence by 2060 compared to baseline model (no effects) outcomes. In contrast, e-cigarette use prevalence among never smokers would have to rise dramatically from current estimates, with e-cigarettes increasing smoking initiation by more than 200% relative to baseline model estimates in order to achieve a corresponding 6% increase in smoking prevalence by 2060. Conclusions Based on current knowledge of the patterns of e-cigarette use by smoking status and the heavy concentration of e-cigarette use among current smokers, the simulated effects of e-cigarettes on smoking cessation generate substantially larger changes to smoking prevalence relative to their effects on smoking initiation.

    To compare recent trends in smoking initiation by adolescents with trends in inflation-adjusted cigarette pricing and tobacco marketing expenditures. We examined smoking initiation trends in demographic subgroups of adolescents aged 14-17 years during the decade 1979-1989. Data on cigarette pricing and tobacco marketing expenditures were adjusted for inflation and plotted over this same period. Large population surveys, United States. 140,975 ever-smokers aged 17-38 when surveyed in 1992 or 1993, who reported on age of smoking initiation during the decade 1979-1989. Initiation rate was calculated as the number in an age group who reported starting to smoke regularly in a year, divided by the number of never-smokers at the start of the year. Trends were evaluated by linear and quadratic models. From 1979 to 1984, adolescent initiation rates decreased, but increased thereafter, particularly among males, whites, and those who, as adults, reported never having graduated from high school. Cigarette price increased throughout the decade as did tobacco marketing expenditures, especially for coupons, value-added items, and promotional allowances. Availability of cheaper cigarettes is not likely to be a cause of increased smoking initiation by adolescents. Although other influences cannot be ruled out, we suspect that the expanded tobacco marketing budget, with its increased emphasis on tactics that may be particularly pertinent to young people, affected adolescent initiation rates.

The effects of smoking by parents and best friend varied with stage of adolescent tobacco smoking. Attributable risk calculations showed that parental and best friend smoking explained only 6.3% of susceptibility to smoking among never smokers, and 21.7% of non-smoking students who had ever experimented with cigarettes. The attributable risk for parental and best friend smoking progressively increased with smoking frequency, up to 78.7% for daily smoking. The effect of best friend smoking was stronger than parental smoking, although there was a synergistic effect of both variables on the risk of daily smoking. Smoking by best friend and parents are strongly associated with current smoking by adolescents, but unrelated to susceptibility to smoke among those who are non-smokers.

    Electronic cigarettes (e-cigarettes) are promoted as smoking cessation tools, yet they remain unavailable from Stop Smoking Services in England; the debate over their safety and efficacy is ongoing. This study was designed to explore perceptions and reasons for use or non-use of electronic cigarettes as smoking cessation tools, among individuals engaged in Stop Smoking Services. Semi-structured telephone interviews were undertaken with twenty participants engaged in Stop Smoking Services in the north-west of England. Participants comprised of both individuals who had tried e-cigarettes (n = 6) and those who had not (n = 14). Interviews were digitally recorded and transcribed verbatim. The transcripts were subject to thematic analysis, which explored participants' beliefs and experiences of e-cigarettes. A thematic analysis of transcripts suggested that the following three superordinate themes were prominent: (1) self-efficacy and beliefs in e-cigarettes; (2) e-cigarettes as a smoking cessation aid; and (3) cues for e-cigarette use. Participants, particularly never users, were especially concerned regarding e-cigarette efficacy and safety. Overall, participants largely expressed uncertainty regarding e-cigarette safety and efficacy, with some evidence of misunderstanding. Evidence of uncertainty and misunderstanding regarding information on e-cigarettes highlights the importance of providing smokers with concise, up-to-date information regarding e-cigarettes, enabling smokers to make informed treatment decisions. Furthermore, identification of potential predictors of e-cigarette use can be used to inform Stop Smoking Services provision and future research. What is already known on this subject? Research suggests that e-cigarettes may help smokers quit smoking, but further studies are needed. Electronic cigarette use in Stop Smoking Services has increased substantially in recent years, although e-cigarettes are currently not regulated. There is debate within the

    Although most US states prohibit cigarette smoking in public places and worksites, fewer jurisdictions regulate indoor use of electronic cigarettes (e-cigarettes). Given the dramatic increase in e-cigarette use and concern about its impact on non-users, there is a need to examine the use of e-cigarettes in smoke-free environments and related attitudes and perceptions. Recruited from a nationally representative adult panel (GfK's KnowledgePanel), 952 current users of e-cigarettes completed a cross-sectional online survey in 2014. Multivariate logistic regressions were conducted to examine the factors associated with ever using e-cigarettes in smoke-free environments. Overall, 59.5% of e-cigarette users had vaped where cigarette smoking was not allowed. Young adults (18-29 years) were most likely to do so, 74.2%. The places of first-time use most often mentioned were service venues (bar, restaurant, lounge and club), 30.7%, followed by worksites, 23.5%. Daily e-cigarette users were more likely to have vaped in smoke-free environments than non-daily users (OR=2.08, p=0.012). Only 2.5% of those who used e-cigarettes in smoke-free environments reported negative reactions from other people. Most e-cigarette users did not think e-cigarettes are harmful to themselves or to by-standers, and thus should not be banned where smoking is; those who had used e-cigarettes where smoking is banned were even more likely to hold these views. E-cigarette use in smoke-free environments was common, suggesting that most e-cigarette users do not consider smoke-free laws to apply to e-cigarettes. Explicit laws should be considered if jurisdictions want to prohibit e-cigarette use in public places. Published by the BMJ Publishing Group Limited.

    Given that little is known about how youth access contraband cigarettes, the current study seeks to examine factors associated with how underage smoking youth report usually accessing contraband cigarettes. This study used nationally representative data collected from 41,886 students (grades 9 to 12) as part of the 2006-07 Canadian Youth Smoking Survey (YSS). Using data from current smokers who report that their usual brand of cigarettes is contraband, three logistic regression models were used to examine factors associated with buying cigarettes from a store, getting cigarettes from a family member, or getting cigarettes from friends or strangers. In 2006, 7.9% (n = 1 3,300) of Canadian youth who were current smokers reported that their usual brand of cigarettes was contraband. Among these youth, the majority reported that they usually get their cigarettes from a friend or stranger (54.8%), whereas 26.4% report usually getting them from a family member and 18.8% usually buying their own from a store. Boys were more likely to buy contraband cigarettes from a store, whereas youth with a parent who smokes contraband cigarettes were substantially more likely to get contraband cigarettes from a family member and youth with friends who smoke contraband cigarettes were substantially more likely to get contraband cigarettes from a friend or stranger. Ongoing surveillance of contraband cigarette use among youth and how youth access contraband cigarettes is required for guiding future tobacco control policy and programming activities.

    The purpose of the study is to examine adolescents' awareness of e-cigarette marketing and investigate the impact of e-cigarette flavour descriptors on perceptions of product harm and user image. Data come from the 2014 Youth Tobacco Policy Survey, a cross-sectional in-home survey conducted with 11-16 year olds across the UK (n = 1205). Adolescents' awareness of e-cigarette promotion, brands, and flavours was assessed. Perceptions of product harm, and likely user of four examples of e-cigarette flavours was also examined. Some participants had tried e-cigarettes (12 %) but regular use was low (2 %) and confined to adolescents who had also smoked tobacco. Most were aware of at least one promotional channel (82 %) and that e-cigarettes came in different flavours (69 %). Brand awareness was low. E-cigarettes were perceived as harmful (M = 3.54, SD = 1.19) but this was moderated by product flavours. Fruit and sweet flavours were perceived as more likely to be tried by young never smokers than adult smokers trying to quit (p < 0.001). There is a need to monitor the impact of future market and regulatory change on youth uptake and perceptions of e-cigarettes.

  1. Influence of the Flavored Cigarette Ban on Adolescent Tobacco Use.

    This paper estimated the association between the U.S. Food and Drug Administration's 2009 ban on flavored cigarettes (which did not apply to menthol cigarettes or tobacco products besides cigarettes) and adolescents' tobacco use. Regression modeling was used to evaluate tobacco use before and after the ban. The analyses controlled for a quadratic time trend, demographic variables, prices of cigarettes and other tobacco products, and teenage unemployment rate. Data from the 1999-2013 National Youth Tobacco Surveys were collected and analyzed in 2016. The sample included 197,834 middle and high schoolers. Outcomes were past 30-day cigarette use; cigarettes smoked in the past 30 days among smokers; rate of menthol cigarette use among smokers; and past 30-day use of cigars, smokeless tobacco, pipes, any tobacco products besides cigarettes, and any tobacco products including cigarettes. Banning flavored cigarettes was associated with reductions in the probability of being a cigarette smoker (17%, p<0.001) and cigarettes smoked by smokers (58%, p=0.005). However, the ban was positively associated with the use by smokers of menthol cigarettes (45%, p<0.001), cigars (34%, p<0.001), and pipes (55%, p<0.001), implying substitution toward the remaining legal flavored tobacco products. Despite increases in some forms of tobacco, overall there was a 6% (p<0.001) reduction in the probability of using any tobacco. The results suggest the 2009 flavored cigarette ban did achieve its objective of reducing adolescent tobacco use, but effects were likely diminished by the continued availability of menthol cigarettes and other flavored tobacco products.

    We assessed the impact of trying electronic cigarettes (e-cigarettes) on future cigarette smoking in a sample of smokers enrolled in college. In this longitudinal study, first-semester college students at 7 colleges in North Carolina and 4 in Virginia completed a baseline survey and 5 follow-up surveys between fall 2010 and fall 2013. Current cigarette smoking at wave 6 was the primary outcome. Participants (n = 271) reported current cigarette smoking at baseline and no history of e-cigarette use. We measured trying e-cigarettes at each wave, defined as use in the past 6 months. By wave 5, 43.5% had tried e-cigarettes. Even after controlling for other variables associated with cigarette smoking, trying e-cigarettes was a significant predictor of cigarette smoking at wave 6 (adjusted odds ratio [AOR] = 2.48; 95% confidence interval [CI] = 1.32, 4.66), as were friends' cigarette smoking (AOR = 4.20; 95% CI = 2.22, 7.96) and lifetime use of other tobacco products (AOR = 1.63; 95% CI = 1.22, 2.17). Trying e-cigarettes during college did not deter cigarette smoking and may have contributed to continued smoking.

    Regional studies have linked exposure to movie smoking with adolescent smoking. We examined this association in a representative US sample. We conducted a random-digit-dial survey of 6522 US adolescents aged 10 to 14 years. Using previously validated methods, we estimated exposure to movie smoking, in 532 recent box-office hits, and examined its relation with adolescents having ever tried smoking a cigarette. The distributions of demographics and census region in the unweighted sample were almost identical to 2000 US Census estimates, confirming representativeness. Overall, 10% of the population had tried smoking. Quartile (Q) of movie smoking exposure was significantly associated with the prevalence of smoking initiation: 0.02 of adolescents in Q1 had tried smoking; 0.06 in Q2; 0.11 in Q3; and 0.22 in Q4. This association did not differ significantly by race/ethnicity or census region. After controlling for sociodemographics, friend/sibling/parent smoking, school performance, personality characteristics, and parenting style, the adjusted odds ratio for having tried smoking were 1.7 (95% confidence interval [CI]: 1.1, 2.7) for Q2, 1.8 (95% CI: 1.2, 2.9) for Q3, and 2.6 (95% CI: 1.7, 4.1) for Q4 compared with adolescents in Q1. The covariate-adjusted attributable fraction was 0.38 (95% CI: 0.20, 0.56), suggesting that exposure to movie smoking is the primary independent risk factor for smoking initiation in US adolescents in this age group. Smoking in movies is a risk factor for smoking initiation among US adolescents. Limiting exposure of young adolescents to movie smoking could have important public health implications.

    There is a growing concern that the historic reductions in tobacco consumption witnessed in the past decades may be undermined by the rapid increase in e-cigarette use. This study examined the association between e-cigarette use and future intention to smoke cigarettes among middle and high school students who had never smoked cigarettes. Data were drawn from the 2014-2015 Canadian Student Tobacco, Alcohol and Drugs Survey (n=25,637). A multivariable logistic regression model was used to examine the association between e-cigarette use and susceptibility to cigarette smoking. In addition, an inverse probability of treatment weighted regression adjustment method (doubly robust estimator), which models both the susceptibility to smoking and the probability of e-cigarette use, was conducted. About 10% of the students had ever tried an e-cigarette. There were higher rates of ever e-cigarette use among students in grades 10-12 (12.5%) than those in grades 7-9 (7.3%). Students who had ever tried an e-cigarette had higher odds of susceptibility to cigarette smoking (adjusted odds ratio=2.16, 95% confidence interval=1.80-2.58) compared to those that had never tried an e-cigarette. Current use of an e-cigarette was associated with higher odds of smoking susceptibility (adjusted odds ratio=2.02, 95% confidence interval=1.43-2.84). Similar results were obtained from the doubly robust estimation. Among students who had never smoked cigarettes, e-cigarette use was associated with a higher susceptibility to cigarette smoking.

    Importance Exposure to nicotine in electronic (e-) cigarettes is common among adolescents who report never having smoked combustible tobacco. Objectives To evaluate whether e-cigarette ever-use among 14-year-olds who have never tried combustible tobacco is associated with risk of initiating use of three combustible tobacco products (i.e., cigarettes, cigars, and hookah). Design Longitudinal repeated assessment of a school-based cohort at baseline (fall 2013, 9th grade, Mean age=14.1) and 6-month (spring 2014, 9th grade) and 12-month (fall 2014, 10th grade) follow-ups. Setting and Participants Ten public high schools in Los Angeles, CA were recruited through convenience sampling. Participants were students who reported never using combustible tobacco at baseline and underwent follow-up assessment (N=2,530). At each time point, students completed self-report surveys during in-classroom data collections. Exposure Self-report of e-cigarette ever-use (yes/no) at baseline. Main Outcome Measures Six- and 12-month follow-up reports of use of each of the following tobacco products within the prior 6 months: (1) any combustible tobacco product (yes/no); (2) combustible cigarettes (yes/no), (3) cigars (yes/no); (4) hookah (yes/no); and (5) number of combustible tobacco products (range: 0–3). Results Past 6-month use of any combustible tobacco product was more frequent in baseline e-cigarette ever-users (N=222) than never-users (N=2,308) at the 6-month (30.7% vs. 8.1%, % difference [95% CI]=22.7[16.4, 28.9]) and 12-month (25.2% vs. 9.3%, % difference [95% CI]= 15.9[10.0, 21.8]) follow-ups. Baseline ever e-cigarette use was associated with greater likelihood of combustible tobacco use averaged across the two follow-ups in unadjusted analyses (OR[95% CI]=4.27[3.19, 5.71]) and in analyses adjusted for sociodemographic, environmental, and intrapersonal risk factors for smoking (OR[95% CI]=2.73[2.00, 3.73]). Product-specific analyses showed that baseline e-cigarette ever-use was

Published Persian-language papers of all types until 2009 indexed in the IranMedex (http://www.iranmedex.com) and Magiran (http://www.magiran.com). Reports of World Health Organization were also searched and optionally employed. The studies concerning passive smoking or presenting the statistically insignificant side effects were excluded. Databases were searched using various combinations of the following terms: cigarette, smoking, smoking cessation, prevalence, history, side effects, and lung cancer by independent reviewers. All the 83 articles concerning the prevalence or side effects of the smoking habit in any Iranian population were selected. The prevalence rate of daily cigarette smoking and the 95% confidence interval as well as smoking health risk associated odds ratio (OR) were retrieved from the articles or calculated. The reported prevalence rates of the included studies, the summary of smoking-related side effects and the ORs (95%CI) of smoking associated risks and the available data on smoking cessation in Iran have been shown in the article. Because of lack of certain data, special studies on local pattern of tobacco use in different districts, about the relationship between tobacco use and other diseases, especially non communicable diseases, and besides extension of smoking cessation strategies, studies on efficacy of these methods seems to be essential in this field.

    The objective of this experiment was to evaluate the comparative value of cigarettes versus high dose e-cigarettes among nicotine-dependent cigarette smokers when compared with money or use of their usual cigarette brand. The experiment used a within-subject design with four sessions. After baseline assessment, participants attended two 15-min unrestricted smoking sessions: one cigarette smoking session and one e-cigarette smoking session. Participants then attended two multiple-choice procedure (MCP) sessions: a session comparing cigarettes and money and a session comparing e-cigarettes and money. Participants (n=27) had used cigarettes regularly, had never used e-cigarettes, and were not currently attempting to quit smoking. The sample consisted primarily of males (72%), with a mean age of 34 years. When given the opportunity to choose between smoking a cigarette or an e-cigarette, participants chose the cigarette 73.9% of the time. Findings from the MCP demonstrated that after the first e-cigarette exposure sessions, the crossover value for cigarettes ($3.45) was significantly higher compared with the crossover value for e-cigarettes ($2.73). The higher participant preference, self-reported smoking effects, and higher MCP crossover points indicate that cigarettes have a higher comparative value than high dose e-cigarettes among e-cigarette naive smokers.

    Perceived safer than tobacco cigarettes, prevalence of electronic cigarette (e-cigarette) use is increasing. Analyses of cartridges suggest that e-cigarettes may pose health risks. In light of increased use and the potential for consequences, we searched Google Scholar and Pubmed in July of 2013 using keywords, such as e-cigarette and vaping, to compare differences and similarities in prevalence and correlates of e-cigarette use among adolescents (grades 6-12) versus adults (aged ≥18 years). Twenty-one studies focused on e-cigarette use. Ever-use increased among various age groups. In 2011, ever-use was highest among young adults (college students and those aged 20-28; 4.9%-7.0%), followed by adults (aged ≥18; 0.6%-6.2%), and adolescents (grades 6-12 and aged 11-19; <1%-3.3%). However, in 2012 adolescent ever-use increased to 6.8% and, among high school students, went as high as 10.0%. While the identified common correlate of e-cigarette use was a history of cigarette smoking, a notable proportion of adolescents and young adults who never smoked cigarettes had ever-used e-cigarettes. E-cigarette use was not consistently associated with attempting to quit tobacco among young adults. Adults most often reported e-cigarettes as a substitute for tobacco, although not always to quit. Reviewed studies showed a somewhat different pattern of e-cigarette use among young people (new e-cigarette users who had never used tobacco) versus adults (former or current tobacco users). Research is needed to better characterize prevalences, use correlates, and motives of use in different population groups, including how adolescent and young adult experimentation with e-cigarettes relates to other types of substance use behaviors.

    Two British boarding schools for boys with different disciplinary policies in respect of cigarette smoking were identified. Questionnaires were sent to the young "old boys" of each school to determine their present smoking habit and most were returned (school A 81%, school B 83%). Significantly more responders smoked who had been to the less strict school (school A 39%, school B 30%, p less than 0.05). These figures probably underestimate the smoking prevalence in the two complete groups. The results suggest that measures that reduce the exposure of an uncommitted adolescent to peer group smoking decrease the chances of tobacco dependence in adulthood. PMID:6816346

    The Po-210 content of tobacco has been known for a long time, however, different results can be found about the estimated amount of Po-210 that is inhaled by humans as a result of smoking cigarettes. Because of the unique properties of Po-210, the smoking machines available on the market are not suitable because of their failure to quantitatively collect Po-210 for measurement. Therefore, to estimate precisely the amount of Po-210 entering the lungs as a result of smoking, a smoking machine and sampling protocol based on relevant ISO standards - ISO-3308, ISO-3402 and ISO-4387 - was developed. A 5% HCl solution was found to be the best absorber of Po-210 from smoke. Seventeen different brands of cigarettes distributed in Iran were used to validate the new machine and sampling protocol. The Po-210 concentration was determined by alpha spectrometry; the cigarette smoke solution underwent combined acid treatment after adding a Po-209 tracer. The Po-210 activity concentration of cigarettes sold in Iran was between 9.7 ± 1.2 and 26.5 ± 4.6 mBq/cigarette and it was determined that there was no relationship between the Po-210 and nicotine contents of cigarette smoke. Additionally, it was found that 15 ± 10% of the cigarette Po-210 was transferred to the mainstream smoke. Copyright © 2017 Elsevier Ltd. All rights reserved.

    We conducted this study to estimate the correlates of current cigarette smoking among in-school adolescents in Jamaica 2006 and compare prevalence of smoking and associated factors between 2000 and 2006. In 2006, 1854 participated of whom 49.5 were males and 50.5% females. 1752 adolescents, 48.8% male and 51.2% females participated in the 2000 survey. Between 2000 and 2006, the prevalence of smoking among Jamaican school-going adolescents went up slightly from 15.2% to 16.7% but this was not statistically significant (p = 0.22). The perception that smoking is not harmful increased from 10.9% to 15.9% while parental smoking decreased from 39.4% to 35.5%. There was a decrease in the rates of adolescents exposed to tobacco adverts on billboards (p-value = 0.037) and in newspapers/magazine (p-value < 0.001). The percentage of adolescents who reported having an item with a tobacco brand logo on it increased from 13.9% to 16.4%. The perception that boys and girls who smoked had more friends increased between 2000 and 2006 (p-values = 0.016 and 0.004 respectively). Current smoking was associated with male gender (OR = 1.55; 95% CI [1.09-2.19]), having smoking parents (OR = 1.75; 95% CI [1.23-2.50]), and smoking friends (OR = 14.94; 95% CI [8.61-25.92] for most or all friends smokers and OR = 4.38; 95% CI [2.93-6.56] for some friends smokers)). Results from this study indicate smoking was positively associated with male gender, having smoking friends or parents. We observed a slightly non significant increase in the prevalence of smoking between 2000 and 2006 among adolescents in Jamaica. Although there was a decrease in the rates of adolescents exposed to advertisement, the percentage of those who had an item with a tobacco brand logo had increased. The possible impact of the Jamaica's ratification of the Framework Convention on Tobacco control remains to be observed.

    Efforts to prevent adolescents from smoking have limited efficacy, with little understanding of why they smoke. We examine many of the factors which may influence a teenager's decision to start smoking. A self-completed questionnaire was distributed among pre-draft teenagers (age 16-18 years) with questions regarding current smoking habits as well as smoking habits of family members. Smokers were asked why they started, and attitudes regarding the dangers of smoking and anti-smoking legislation were examined. A total of 1067 questionnaires were completed (707 males, 360 females). In all, 25.7% were current smokers (26.2% of male and 21.1% of females; p=0.069), with smoking rates highest among those born in Middle Eastern countries and lowest among those born in Ethiopia. Those from single-parent families had a higher smoking rate (relative risk: 1.28), as did those with either parents or siblings who smoked. Parents who were smokers were more likely to tell their children not to smoke, while smoking teenagers were more likely to have been told by their parents not to smoke. Most smokers (58.2%) did not give a specific reason for smoking while 30.3% listed "peer pressure", 8.4% "parents smoking" and 3.1% "advertisements" as the major factor. Smokers were less likely to agree that smoking is harmful and more likely to oppose anti-smoking legislative measures. Many factors influence a teenager's decision to smoke, including cultural norms and habits of friends and family members. Educating both adolescents and those around them may help prevent smoking among this age group.

    Despite the lack of clarity regarding their safety and efficacy as smoking cessation aids, electronic or e-cigarettes are commonly used to quit smoking. Currently little is understood about why smokers may use e-cigarettes for help with smoking cessation compared to other, proven cessation aids. This study aimed to determine the reasons for wanting to quit cigarettes that are associated with the use of e-cigarettes for cessation help versus the use of conventional Nicotine Replacement Therapy (NRT) products (e.g., gums). Cross-sectional, self-report data were obtained from multiethnic 1988 current daily smokers [M age = 45.1 (SD = 13.0); 51.3% Women] who had made an average lifetime quit attempts of 8.5 (SD = 18.7) but were not currently engaged in a cessation attempt. Reasons for wanting to quit smoking were assessed by using the Reasons for Quitting (RFQ) scale. Path analyses suggested that among reasons for quitting cigarettes, “immediate reinforcement,” a measure of wanting to quit cigarettes for extrinsic reasons such as bad smell, costliness and untidiness, was significantly associated with having tried e-cigarettes for cessation help, and “concerns about health” was associated with having tried NRT-only use. E-cigarettes appear to provide an alternative “smoking” experience to individuals who wish to quit cigarette smoking because of the immediate, undesirable consequences of tobacco smoking (e.g., smell, ash, litter) rather than concerns about health. Provided that the safety of e-cigarette use is ensured, e-cigarettes may be effectively used to reduce tobacco exposure among smokers who may not want to quit cigarettes for intrinsic motivation.

    Objectives This experiment tested whether changing the location or visibility of the tobacco power wall in a life sized replica of a convenience store had any effect on adolescents’ susceptibility to future cigarette smoking. Methods The study was conducted in the RAND StoreLab (RSL), a life sized replica of a convenience store that was developed to experimentally evaluate how changing aspects of tobacco advertising displays in retail point-of-sale environments influences tobacco use risk and behavior. A randomized, between-subjects experimental design with three conditions that varied the location or visibility of the tobacco power wall within the RSL was used. The conditions were: cashier (the tobacco power wall was located in its typical position behind the cash register counter); sidewall (the tobacco power wall was located on a sidewall away from the cash register); or hidden (the tobacco power wall was located behind the cashier but was hidden behind an opaque wall). The sample included 241 adolescents. Results Hiding the tobacco power wall significantly reduced adolescents’ susceptibility to future cigarette smoking compared to leaving it exposed (i.e., the cashier condition; p = .02). Locating the tobacco power wall on a sidewall away from the cashier had no effect on future cigarette smoking susceptibility compared to the cashier condition (p = 0.80). Conclusions Hiding the tobacco power wall at retail point-of-sale locations is a strong regulatory option for reducing the impact of the retail environment on cigarette smoking risk in adolescents.

The secondary aim was to test whether these trends differed between adolescents of higher and lower socio-economic position (SEP). Repeated cross-sectional data were used in a quasi-experimental pre-post design. Intervention countries raised tobacco sales restrictions to 18 years in 2007, 2008 or 2009. Control countries have had sales restrictions of 18 years since at least 2004. Nineteen European Union (EU) countries in 2007 and 2011. Data of 97 245 15- and 16-year-old adolescents from the 2007 and 2011 European Survey Project on Alcohol and other Drugs (ESPAD) surveys. Dependent variables were smoking status (weekly smoking versus non-smoking or less than weekly smoking) and perceived obtainability of tobacco (easy versus difficult). Key independent variables were time (2007 or 2011), intervention exposure (intervention or control country) and their interaction (time × intervention). Covariates included sex, SEP, the tobacco control scale (TCS), gross domestic product (GDP) and adult smoking prevalence. We did not find a difference in the change in smoking prevalence between intervention and control countries [odds ratio (OR) = 1.00, 95% confidence interval (CI) = 0.93-1.07]. However, sales restrictions were associated with a significantly greater decrease in perceived ease of cigarette obtainability in intervention countries (OR = 0.75, 95% CI = 0.70-0.80). No significant differential effects between high and low SEP adolescents were found (OR = 1.01, 95% CI = 0.81-1.25). Laws prohibiting the sales of tobacco to minors in Europe do not appear to be associated with a reduction

    Introduction: This study examined the relationship between the time to the first cigarette (TTFC) of the morning with quit status among adolescent smokers at the completion of a school-based smoking cessation program. Among those who did not quit, the relationship of TTFC with changes in cigarettes/day (CPD) was also examined. Methods: A total of 1,167 adolescent smokers (1,024 nonquitters and 143 quitters) from 4 states participating in efficacy and effectiveness studies of the Not-On-Tobacco (N-O-T) cessation program were assessed prior to entry into the program and again 3 months later at the end of treatment. Linear and logistic regression analyses determined the influence of treatment condition, age, gender, motivation to quit, confidence in quitting ability, baseline CPD, and TTFC on quit status and end-of-treatment CPD. Results: Adolescents with a TTFC of >30min of waking were twice as likely to quit at end of treatment. Additionally, among those who did not quit at end of treatment (n = 700 for TTFC ≤30min and n = 324 for TTFC for >30min), those with a TTFC within 30min of waking smoked a greater number of CPD. The relationships of TTFC with both of these outcomes remained when controlling for all other predictor variables. Conclusions: Identifying adolescent smokers who smoke their first cigarette of the day within the first 30min of waking prior to a quit attempt may help to classify those individuals as having a greater risk for cessation failure. Thus, TTFC may be a behavioral indicator of nicotine dependence in adolescents. PMID:23811009

    To examine how saturation of an adolescent's environment with models of cigarette smoking (e.g., parents, siblings, friends) affects the probability of tobacco and alcohol use among junior high and high school students. The Health and Smoking Questionnaire was administered to 806 adolescents (182 smokers and 624 nonsmokers; 57.2% female) average age of 15.1 years (SD = 1.6) in a mid-size Midwestern town. The questionnaire contains standardized items in five domains: demographics, smoking status and history, perceptions of risk and risk reduction, risk factors for tobacco use, and parenting style. Risk for smoking or using alcohol increased dramatically as the number of models who smoke increased in an adolescent's environment. For instance, adolescents with one significant other who smoked were nearly four times (OR = 3.76, p <.001) more likely to smoke than someone with no significant others who smoked. However, if an adolescent had four significant others who smoked, they were over 160 times more likely to smoke (OR = 161.25, p <.001). Similar results were found for alcohol use; adolescents who had one significant other who smoked were more than 2.5 (OR = 2.66, p <.001) times more likely to drink than those without smoking models. Adolescents who had four significant other smoking models were 13 times (OR = 13.08, p <.001) more likely to drink. As the number of cigarette smokers in an adolescent's environment increases, risk of tobacco and alcohol use increases substantially. These data suggest that multiple models of tobacco use will substantially increase risk for substance use in adolescents.

    Hungary will continue to experience a high burden of disease and death from lung cancer and other tobacco-induced disease unless there is a significant reduction in youth smoking. Social factors have been found to be among the most important determinants of adolescent smoking, yet few studies have investigated social normative beliefs in Hungarian youth. The purpose of the current study was to investigate three measures of smoking normative beliefs thought to influence adolescent smoking: perceived prevalence of smoking; perceived popularity of smoking among successful/elite elements of society; and perceived disapproval by friends and family. A cross-sectional school-based survey of eighth grade (n = 258) and 12th grade (n = 288) students in Mako, Hungary was conducted to assess social normative beliefs about smoking, current smoking, ever smoking, and susceptibility to smoking. The association of the normative beliefs with the smoking behavior variables was examined through logistic regression analysis, and the underlying factor structure of the normative belief items in the current sample was determined through factor analysis. The percent of boys reporting current smoking was 40.5% in 12th grade and 27.0% in eighth grade. Among girls, the percent was 44.0% of 12th graders and 29.1% of eighth graders. Parent/peer disapproval was the most consistently associated normative belief with smoking behavior and susceptibility to smoking across both samples. Youth smoking prevention programs should consider assessing and taking into account normative beliefs and develop strategies that provide accurate information about the actual prevalence of smoking, the types of individuals who smoke, and approval/disapproval of smoking by parents and peers. © 2011 The Authors.

    A cross-sectional questionnaire study of the correlates of ever-smoking among adolescents was made in Tabuk government schools in Saudi Arabia. Of 1505 students aged 12-19 years, 657 (43.7%) were ever-smokers (i.e. ever tried cigarette smoking, even 1 or 2 puffs); 65.0% of males and 23.1% of females. In logistic regression analysis significant predictors for ever-smoking were: male sex, belief that smoking helps people feel comfortable in social situations, owning something with a cigarette logo, having pocket money > or = 20 riyals/day, poor school performance and having friends or parents who smoked.

    There is limited evidence on how cigarette smokers use electronic cigarettes (ECIGs) for smoking cessation and reduction. This study used concept mapping, a participatory mixed-methods research approach, to identify ECIG use behaviors and device characteristics perceived to be associated with cigarette smoking cessation or reduction. Current ECIG users aged 18-64 were recruited from seven cities selected randomly from U.S. census tract regions. Participants were invited to complete concept mapping tasks: brainstorming, sorting and rating (n=72). During brainstorming, participants generated statements in response to a focus prompt ("A SPECIFIC WAY I HAVE USED electronic cigarettes to reduce my cigarette smoking or a SPECIFIC WAY electronic cigarettes help me reduce my cigarette smoking is…") and then sorted and rated the statements. Multidimensional scaling and hierarchical cluster analyses were used to generate a cluster map that was interpreted by the research team. Eight thematic clusters were identified: Convenience, Perceived Health Effects, Ease of Use, Versatility and Variety, Advantages of ECIGs over Cigarettes, Cigarette Substitutability, Reducing Harms to Self and Others, and Social Benefits. Participants generated several statements that related to specific behavioral strategies used when using ECIGs for smoking reduction/complete switching behaviors such as making rapid transitions from smoking to ECIG use or using certain ECIG liquids or devices. Former smokers rated the Perceived Health Effects cluster and several behavioral strategy statements higher than current smokers. These results help to identify ECIG use behaviors and characteristics perceived by ECIG users to aid in cigarette smoking cessation or reduction. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Whether the use of smokeless tobacco can facilitate the transition to cigarette smoking and/or to prolonged tobacco use in adolescence is unclear. We analyzed data from a cohort of 2,938 Swedish adolescents, with six follow-up assessments of tobacco use between the ages of 11 and 18 years. The majority of tobacco users (70%) started by smoking cigarettes, 11% took up snus before smoking, and 19% used both tobacco types close in time. Ever users of tobacco at baseline had a higher risk of being current smokers and/or smokeless tobacco users at the end of follow-up compared with never users, with the highest excess relative risk for "mixed users." Adolescents who initiated tobacco use with cigarettes had a non-significantly increased probability to end up as current smokers compared with snus starters (adjusted OR=1.42; 95% CI 0.98-2.10) The OR of smoking for "mixed starters" was 2.54 (95% CI 1.68-3.91). The risk of becoming current user of any tobacco was also significantly enhanced for "mixed starters." Marked sex differences were observed in these associations, as initiation with cigarettes rather than with snus predicted current smoking or tobacco use only among females. Progression of tobacco use in adolescence is not predicted by onset with snus or cigarettes, but rather by initiation with both tobacco types close in time and/or at young age. The proportion of adolescent smoking prevalence attributable to a potential induction effect of snus is likely small.

    To gather information on inter-relationships among risk factors affecting adolescent smoking for tobacco control in China, the world's largest tobacco producer and consumer. Longitudinal data were collected six months apart in 2003 from 813 students in grades 7, 8, 10, and 11 from two schools in Beijing, China. Linear regression was used to assess both the direct effect from predictor variables (smoking among influential others, pro-tobacco media, and attitudes toward smoking) on cigarette use and the indirect effect mediated through the perceived smoking norms (percentage of smokers among peers). Among the 803 subjects (mean age of 15.5 years, SD = 1.7; 52.1% female), 18.3% of males and 1.7% of females smoked in the past 30 days. Smoking among influential others (best friends, father, mother, male teachers, female teachers, and adults in general) and perceived positive psychological and social rewards from smoking at baseline were associated with number of cigarettes smoked at follow-up, whereas exposure to pro-tobacco media was not significantly associated with smoking. The mediated effect was greater for adult smoking (70% to 90%) than for best friend smoking (11% to 16%). Smoking among influential others and attitudes toward smoking influence adolescent smoking both directly and indirectly. The finding of the indirect effect mediated through perceived smoking norms expands our knowledge on smoking etiology. Effective adolescent smoking intervention programs in China need to include a component targeting adult smoking to reduce perceived smoking norms.

    This study compared adolescents' unbiased perceptions of the images displayed in smoking and antismoking advertising. Twenty-nine adolescents (ages 11-17) were shown images taken from both advertising types; all images were digitally edited so that no product information appeared in them. Participants described each image in a free-response format and rated each image on self-report dimensions. Content analyses of free-response descriptions and analyses of self-reports revealed that adolescents viewed images taken from cigarette advertisements more positively compared with images taken from antismoking advertisements. These findings suggest that I reason for the potency of cigarette advertising, compared with antismoking advertising, is the inherent positive appeal of the images displayed. Antismoking advertising may be more effective at limiting adolescent smoking if the images displayed have a more positive valence.

    To identify the sources used by young adolescents to obtain cigarettes. In early 1994 a survey assessing usual sources of cigarettes and characteristics of the respondents was administered in homeroom classes. A large urban, predominantly African American school system. A population-based sample of 6967 seventh graders averaging 13 years of age. Reports of usual sources of cigarettes. At this age level, young smokers were more likely to get cigarettes from friends (31.2%) than buy them in stores (14.3%). However, the odds of purchasing varied for different groups of children. Regular smokers were much more likely (48.3%) to have purchased cigarettes than experimental smokers (9.6%), p < 0.001. Girls were less likely to have bought their cigarettes than boys (p < 0.001), and black smokers were less likely to have purchased cigarettes than white children (p < 0.001). Results suggested that family members who smoke may constitute a more important source of tobacco products than previously recognised, particularly for young girls. In this middle-school sample, peers provided the major point of cigarette distribution. However, even at this age, direct purchase was not uncommon. Sources of cigarettes varied significantly with gender, ethnicity, and smoking rate.

    The objective of the study was to determine the brand distribution of premium, discount, and native cigarette brands and to identify the factors associated with smoking these brands among a nationally representative sample of Canadian youth smokers. Data from 3,137 current smokers in Grades 9-12 participating in the 2008-2009 Youth Smoking Survey (YSS) were used to examine the prevalence and factors associated with different cigarette brand preferences. The most prevalent brand of cigarette smoked was premium cigarettes (44.7%), followed by discount cigarettes (33.7%), and to be native cigarettes (7.3%). There was significant variability in brand preference by province with the majority of youth in Atlantic Canada and Quebec smoking a discount brand of cigarettes and higher prevalence rates of native cigarette use in Ontario and Quebec. Respondents were more likely to smoke discount cigarettes if they were female, daily smokers, or if they only had $1-20 a week in spending money. Respondents were more likely to smoke native cigarettes if they were Aboriginal, heavier smokers, or if they reported having no weekly spending money. A significant proportion of students from Grade 9 to 12 in Canada smoke cigarettes that are more affordable than premium brands and it appears that the market share for these more affordable cigarette options has increased in recent years. Given that the price of cigarettes is an important determinant in youth smoking behavior, it is critical to develop and continue to enforce tobacco control strategies designed to eliminate access to cheaper sources of cigarettes among youth populations.

    Introduction: Use of electronic nicotine delivery systems (ENDS), including electronic cigarettes (e-cigarettes), is increasing. One concern is the appeal of these products to youth and young adults and the potential to influence perceptions and use of conventional cigarettes. Methods: Using data from the 2012–2013 National Adult Tobacco Survey, characteristics of adults aged 18–29 years who had never established cigarette smoking behavior were examined by ever use of e-cigarettes, demographics, and ever use of other tobacco products (smokeless tobacco, cigars, hookah, and cigarettes). Multivariate logistic regression was used to examine the relationship between e-cigarette use and openness to cigarette smoking among young adults, defined as the lack of a firm intention not to smoke soon or in the next year. Results: Among young adults who had never established cigarette smoking behavior (unweighted n = 4,310), 7.9% reported having ever tried e-cigarettes, and 14.6% of those who reported having ever tried e-cigarettes also reported current use of the product. Ever e-cigarette use was associated with being open to cigarette smoking (adjusted odds ratio = 2.4; 95% confidence interval = 1.7, 3.3), as was being male, aged 18–24 years, less educated, and having ever used hookah or experimented with conventional cigarettes. Conclusions: Ever use of e-cigarettes and other tobacco products was associated with being open to cigarette smoking. This study does not allow us to assess the directionality of this association, so future longitudinal research is needed to illuminate tobacco use behaviors over time as well as provide additional insight on the relationship between ENDS use and conventional cigarette use among young adult populations.

    Adolescent e-cigarette use (i.e., "vaping") likely confers risk for developing nicotine dependence. However, there have been no studies assessing e-cigarette nicotine dependence in youth. We evaluated the psychometric properties of the 4-item Patient-Reported Outcomes Measurement Information System Nicotine Dependence Item Bank for E-cigarettes (PROMIS-E) for assessing youth e-cigarette nicotine dependence and examined risk factors for experiencing stronger dependence symptoms. In 2017, 520 adolescent past-month e-cigarette users completed the PROMIS-E during a school-based survey (50.5% female, 84.8% White, 16.22[1.19] years old). Adolescents also reported on sex, grade, race, age at e-cigarette use onset, vaping frequency, nicotine e-liquid use, and past-month cigarette smoking. Analyses included conducting confirmatory factor analysis and examining the internal consistency of the PROMIS-E. Bivariate correlations and independent-samples t-tests were used to examine unadjusted relationships between e-cigarette nicotine dependence and the proposed risk factors. Regression models were run in which all potential risk factors were entered as simultaneous predictors of PROMIS-E scores. The single-factor structure of the PROMIS-E was confirmed and evidenced good internal consistency. Across models, larger PROMIS-E scores were associated with being in a higher grade, initiating e-cigarette use at an earlier age, vaping more frequently, using nicotine e-liquid (and higher nicotine concentrations), and smoking cigarettes. Adolescent e-cigarette users reported experiencing nicotine dependence, which was assessed using the psychometrically sound PROMIS-E. Experiencing stronger nicotine dependence symptoms was associated with characteristics that previously have been shown to confer risk for frequent vaping and tobacco cigarette dependence.

  10. The influence of self-esteem, parental smoking, and living in a tobacco production region on adolescent smoking behaviors.

    1988-12-01

    Selected antecedents of smoking initiation among 1,513 eighth grade students in an urban tobacco producing county of North Carolina were studied using the Tobacco Cigarette Smoking Questionnaire and the Rosenberg Self-Esteem Scale. Fifteen percent of students reported currently smoking, and 17.2% indicated an intention to smoke upon graduation from high school. Self-esteem and parental smoking behavior related significantly to adolescents' smoking behavior and future intention to smoke. Significantly more females intended to smoke and had lower self-esteem than males. Family involvement in the tobacco industry related significantly to adolescents' intention to smoke but not their smoking behavior. Overall, low self-esteem and parental smoking models may be important to developing the smoking habit among young adolescents. Prevention of smoking initiation should involve promotion of children's self-esteem and avoidance of parental smoking modeling prior to the eighth grade.

    Smoking conventional lit-end cigarettes results in exposure of nonsmokers to potentially harmful cigarette smoke constituents present in environmental tobacco smoke (ETS) generated by sidestream smoke emissions and exhaled mainstream smoke. ETS constituent concentrations generated by a conventional lit-end cigarette and a newly developed electrically heated cigarette smoking system (EHCSS) that produces only mainstream smoke and no sidestream smoke emissions were investigated in simulated "office" and "hospitality" environments with different levels of baseline indoor air quality. Smoking the EHCSS (International Organisation for Standardization yields: 5 mg tar, 0.3 mg nicotine, and 0.6 mg carbon monoxide) in simulated indoor environments resulted in significant reductions in ETS constituent concentrations compared to when smoking a representative lit-end cigarette (Marlboro: 6 mg tar, 0.5 mg nicotine, and 7 mg carbon monoxide). In direct comparisons, 24 of 29 measured smoke constituents (83%) showed mean reductions of greater than 90%, and 5 smoke constituents (17%) showed mean reductions between 80% and 90%. Gas-vapor phase ETS markers (nicotine and 3-ethenylpyridine) were reduced by an average of 97% (range 94-99%). Total respirable suspended particles, determined by online particle measurements and as gravimetric respirable suspended particles, were reduced by 90% (range 82-100%). The mean and standard deviation of the reduction of all constituents was 94 +/- 4%, indicating that smoking the new EHCSS in simulated "office" and "hospitality" indoor environments resulted in substantial reductions of ETS constituents in indoor air.

    Several cross-sectional studies have examined factors associated with support for tobacco control policies. The current study utilized a longitudinal design to test smoking status and attitude toward smoking measured in adolescence as prospective predictors of support for tobacco control policies measured in adulthood. Participants (N = 4,834) were from a longitudinal study of a Midwestern community-based sample. Hierarchical multiple regression analyses tested adolescent smoking status and attitude toward smoking as prospective predictors (after controlling for sociodemographic factors, adult smoking status, and adult attitude toward smoking) of support for regulation of smoking in public places, discussion of the dangers of smoking in public schools, prohibiting smoking in bars, eliminating smoking on television and in movies, prohibiting smoking in restaurants, and increasing taxes on cigarettes. Participants who smoked during adolescence demonstrated more support for discussion of the dangers of smoking in public schools and less support for increasing taxes on cigarettes but only among those who smoked as adults. Those with more positive attitudes toward smoking during adolescence demonstrated less support as adults for prohibiting smoking in bars and eliminating smoking on television and in movies. Moreover, a significant interaction indicated that those with more positive attitudes toward smoking as adolescents demonstrated less support as adults for prohibiting smoking in restaurants, but only if they became parents as adults. This study's findings suggest that interventions designed to deter adolescent smoking may have future benefits in increasing support for tobacco control policies.

    There is a dearth of research into whether electronic nicotine delivery systems (ENDS) promote acceptance of cigarette smoking. Therefore, we aimed to assess the association between ENDS exposure, acceptance of cigarette smoking, and susceptibility to cigarette smoking. Data from the 2014 Florida Youth Tobacco Survey with a state representative sample of middle and high school students (n = 68,928) were analyzed. Own ENDS use, exposure to ENDS advertising, living with ENDS users, acceptance of adult cigarette smoking, demographics, and known predictors of cigarette smoking were assessed. Susceptibility to cigarette smoking was assessed among never smokers. Weighted multiple logistic regression models and mediation analyses were conducted, stratified by middle/high school and never/ever smoking. Analyses were conducted in 2016. Own ENDS use, exposure to ENDS advertising, and living with ENDS users were associated with acceptance of adult cigarette smoking even among never smokers, after accounting for covariates (p < .05). In a mediation analysis, own ENDS use, exposure to ENDS advertising, and living with ENDS users were indirectly associated with susceptibility to cigarette smoking among never smokers through acceptance of adult cigarette smoking (p < .05). Youth ENDS exposure may contribute to normalizing adult cigarette smoking and may in turn heighten susceptibility to cigarette smoking. If confirmed by longitudinal studies, these findings suggest that ENDS policy interventions may help prevent youth cigarette smoking. Published by Elsevier Inc.

    1981-01-01

    We have studied the dynamics of marihuana smoking, the plasma concentration of delta 9-tetrahydrocannabinol (THC), and the pharmacologic effects produced by the sequential smoking of two 1% marihuana cigarettes at a 2-hour interval. Three males and three females, experienced marihuana smokers, participated in the study. The results indicate that each subject smoked his or her two cigarettes at a similar rate. The THC plasma concentrations produced by the smoking of the second cigarette were slightly lower than those produced by the first cigarette. The levels of the psychologic "high" caused by the two cigarettes were similar. However, the first cigarette accelerated the heart twice as much as the second cigarette. Between males and females there were marked differences in the rate at which the cigarettes were smoked. In particular, males took more puffs, took them more often, and consumed the cigarettes more rapidly than females. The plasma concentrations of THC, the self-reported psychologic effects, and the heart rate acceleration produced by the smoking of the two cigarettes were identical between the sexes.

    Earlier studies have shown a relation between prenatal cigarette smoke exposure (PCSE) and offspring initiation of tobacco use. No prior study has examined the association between PCSE and early initiation of multiple substances (EIMS) including marijuana and alcohol in addition to tobacco. We investigated the association between PCSE and multiple substance use during adolescence. Pregnant women attending an urban prenatal clinic were selected to participate in the prospective longitudinal study based on their substance use. This study is based on the 16-year follow-up phase and consists of 579 mother-offspring dyads. The women were of lower socioeconomic status, 54% were Black, and 53% reported smoking cigarettes. 52% of the offspring were female. EIMS is a measure of the number of substances initiated prior to age 16 by the adolescents; it ranged from 0 (no initiation, N = 166) to 3 (all, N = 162). Adolescents exposed to tobacco during first trimester of gestation were 1.4 times more likely to initiate multiple substances by age 16 than the nonexposed group. PCSE was a significant predictor of EIMS after controlling for other prenatal exposures, home environment, and demographic characteristics, using ordinal polytomous logistic regression. Other risk factors of EIMS were maternal and adolescent depression, less strict and less involved parenting, offspring attention problems, and lack of participation in a youth club. There is a significant relation between PCSE and adolescent's EIMS.

    Early smoking is considered an indicator for risky behaviour in adolescents. Although social indicators predicting adolescent smoking are known, biological indicators have not been defined. This study aimed to establish whether salivary testosterone could be used as a "predictive biomarker" for smoking-associated peer pressure. Saliva samples were collected from Bruneian adolescents (aged 13-17 years) by the passive drool method. Salivary testosterone concentration was determined by enzyme-linked immunosorbent assay. Salivary testosterone concentration and smoking-associated peer pressure indicators were compared between adolescent males and females and statistical significance was determined by an independent samples t-test. A significant positive relationship between smoking-associated peer pressure and salivary testosterone levels in adolescents was found. However, this relationship was not significant when males and females were considered separately. Our data suggest that students who have tried cigarette smoking and have friends who are cigarette smokers have higher salivary testosterone levels.

    The study objectives were to determine the effects of smoking machine puffing parameters on mainstream smoke composition and to express those effects as predicting relationships. Forty-eight commercial Philip Morris USA and Philip Morris International cigarettes from international markets and the 1R4F reference cigarette were machine-smoked using smoking conditions defined by the International Organization of Standardization (ISO), the Massachusetts Department of Public Health (MDPH), and Health Canada (HC). Cigarette tobacco fillers were analyzed for nitrate, nicotine, tobacco-specific nitrosamines (TSNA), and ammonia. Mainstream yields for tar and 44 individual smoke constituents and "smoke pH" were determined. Cigarette constituent yields typically increased in the order ISOcigarettes with higher initial filter ventilation and were also generally greater for vapor-phase constituents than for particulate-phase constituents. Predicting relationships were developed between ISO tar and ISO, MDPH, and HC constituent yields and between MDPH tar and HC tar and respective smoking condition yields. MDPH and HC constituent yields could be predicted with similar reliability using ISO tar or the corresponding smoking-condition tar. The reliability of the relationships varied from strong to weak, depending on particular constituents. Weak predicting relationships for nitrogen oxides and TSNA's, for example, were improved with inclusion of tobacco filler composition factors. "Smoke pH" was similar for all cigarettes at any one smoking condition, and overall marginally lower at HC conditions than at ISO or MDPH conditions.

    Moderate to severe premenstrual syndrome (PMS) affects as many as 20% of premenopausal women. Although smoking may be more common in women with PMS, it is unknown whether smoking is involved in PMS etiology. In 1991–2001, the authors conducted a case-control study nested within the prospective Nurses’ Health Study II. Participants were US women aged 27–44 years and free of PMS at baseline, including 1,057 who developed PMS over 10 years and 1,968 reporting no diagnosis of PMS and only minimal menstrual symptoms during this time. Smoking at various ages was assessed by questionnaires. After adjustment for oral contraceptives and other factors, current smokers were 2.1 times as likely as never smokers to develop PMS over the next 2–4 years (95% confidence interval: 1.56, 2.83). Total pack-years and smoking during adolescence and young adulthood were also independently associated with a higher risk of PMS. For example, the relative risk for women who started smoking before age 15 years, compared with never smokers, was 2.53 (95% confidence interval: 1.70, 3.76). Results suggest that smoking, especially in adolescence and young adulthood, may increase risk of moderate to severe PMS. These findings may provide an additional incentive for young women to avoid cigarette smoking. PMID:18701443

    Alternative tobacco products such as clove (kreteks) and bidi cigarettes have become increasingly popular among US smokers. The nicotine content of a popular clove cigarette (Djarum Special) filler averaged 7.4 mg; conventional cigarettes contained 13.0 mg. However, smoke yields from standardized machine-smoking analysis indicated it delivered more nicotine, carbon monoxide (CO), and tar than conventional cigarettes. In a clinical study, nicotine delivery, physiologic, and subjective effects of the clove cigarette were compared to their own brand of cigarette in 10 adult smokers (7 males). Average time to smoke the clove cigarette (549 s) and number of puffs (15.1) were significantly greater than own brand (314 s and 9.4 puffs). Increases in venous plasma nicotine and exhaled CO after smoking the clove cigarette (17.4 ng/ml; 6 ppm) were similar to those after own brand (17.6 ng/ml; 4.5 ppm). Maximal changes in heart rate (HR), systolic, and diastolic blood pressures (BP) did not differ significantly between the clove and own brand of cigarette. Compared to their own brand of cigarette, the clove cigarette was rated as better tasting and being distinctly different. Our findings indicate that clove cigarettes deliver significant quantities of nicotine, CO, and presumably other toxic components of tobacco smoke. Taste satisfaction, aromatic odor, and novelty may contribute to their appeal to young smokers.

  2. [Electronic Cigarettes: Lifestyle Gadget or Smoking Cessation Aid?].

    PubMed

    Schuurmans, Macé M

    2015-07-01

    Electronic cigarettes (e-cigarettes) are vaporisers of liquids often containing nicotine. In the inhaled aerosol carcinogens, ultrafine and metal particles are detected usually in concentrations below those measured in tobacco smoke. Therefore, these products are expected to be less harmful. This has not yet been proven. The long-term safety of e-cigarettes is unknown. Short duration use leads to airway irritation and increased diastolic blood pressure. So far only two randomised controlled trials have investigated efficacy and safety of e-cigarettes for smoking cessation: No clear advantage was shown in comparison to smoking cessation medication. Due to insufficient evidence, e-cigarettes cannot be recommended for smoking cessation. Problematic are the lack of regulation and standardisation of e-cigarette products, which makes general conclusions impossible.

    Use of electronic nicotine delivery systems (ENDS), including electronic cigarettes (e-cigarettes), is increasing. One concern is the appeal of these products to youth and young adults and the potential to influence perceptions and use of conventional cigarettes. Using data from the 2012-2013 National Adult Tobacco Survey, characteristics of adults aged 18-29 years who had never established cigarette smoking behavior were examined by ever use of e-cigarettes, demographics, and ever use of other tobacco products (smokeless tobacco, cigars, hookah, and cigarettes). Multivariate logistic regression was used to examine the relationship between e-cigarette use and openness to cigarette smoking among young adults, defined as the lack of a firm intention not to smoke soon or in the next year. Among young adults who had never established cigarette smoking behavior (unweighted n = 4,310), 7.9% reported having ever tried e-cigarettes, and 14.6% of those who reported having ever tried e-cigarettes also reported current use of the product. Ever e-cigarette use was associated with being open to cigarette smoking (adjusted odds ratio = 2.4; 95% confidence interval = 1.7, 3.3), as was being male, aged 18-24 years, less educated, and having ever used hookah or experimented with conventional cigarettes. Ever use of e-cigarettes and other tobacco products was associated with being open to cigarette smoking. This study does not allow us to assess the directionality of this association, so future longitudinal research is needed to illuminate tobacco use behaviors over time as well as provide additional insight on the relationship between ENDS use and conventional cigarette use among young adult populations. © The Author 2014.

    Secondhand smoke (SHS) directly increases exposure to airborne nicotine, tobacco's main psychoactive substance. When exposed to SHS, nonsmokers inhale 60% to 80% of airborne nicotine, absorb concentrations similar to those absorbed by smokers, and display high levels of nicotine biomarkers. Social modeling, or observing other smokers, is a well-established predictor of smoking during adolescence. Observing smokers also leads to increased pharmacological exposure to airborne nicotine via SHS. The objective of this study is to investigate whether greater exposure to airborne nicotine via SHS increases the risk for smoking initiation precursors among never-smoking adolescents. Secondary students ( N = 406; never-smokers: n = 338, 53% girls, mean age = 12.9, SD = 0.4) participated in the AdoQuest II longitudinal cohort. They answered questionnaires about social exposure to smoking (parents, siblings, peers) and known smoking precursors (eg, expected benefits and/or costs, SHS aversion, smoking susceptibility, and nicotine dependence symptoms). Saliva and hair samples were collected to derive biomarkers of cotinine and nicotine. Adolescents wore a passive monitor for 1 week to measure airborne nicotine. Higher airborne nicotine was significantly associated with greater expected benefits ( R 2 = 0.024) and lower expected costs ( R 2 = 0.014). Higher social exposure was significantly associated with more temptation to try smoking ( R 2 = 0.025), lower aversion to SHS ( R 2 = 0.038), and greater smoking susceptibility ( R 2 = 0.071). Greater social exposure was significantly associated with more nicotine dependence symptoms; this relation worsened with higher nicotine exposure (cotinine R 2 = 0.096; airborne nicotine R 2 = 0.088). Airborne nicotine exposure via SHS is a plausible risk factor for smoking initiation during adolescence. Public health implications include limiting airborne nicotine through smoking bans in homes and cars, in addition to stringent restrictions

    2015-03-01

    Electronic cigarettes (E-cigarettes) are devices that can vaporize a nicotine solution combined with liquid flavors instead of burning tobacco leaves. Since their emergence in 2004, E-cigarettes have become widely available, and their use has increased exponentially worldwide. E-cigarettes are aggressively advertised as a smoking cessation aid; as healthier, cheaper, and more socially acceptable than conventional cigarettes. In recent years, these claims have been evaluated in numerous studies. This review explores the development of the current E-cigarette and its market, prevalence of awareness, and use. The review also explores the beneficial and adverse effects of E-cigarettes in various aspects in accordance with recent research. The discussed aspects include smoking cessation or reduction and the health risks, social impact, and environmental consequences of E-cigarettes. © 2014 New York Academy of Sciences.

    The aim was to investigate associations between e-cigarette use and social and psychosocial factors and cigarette smoking, alcohol consumption, and narcotics use among adolescents attending 9th grade in primary school and 2nd grade in secondary school. Cross-sectional study. The public health survey among adolescents in Scania in 2016 includes pupils in grades 9 and 2. The associations between e-cigarette use and lifestyle, social and psychosocial factors, and trust were investigated with logistic regressions. In 9th grade, 32% of male pupils and 27% of female pupils had ever used e-cigarettes, and in 2nd grade, 43% of males and 31% of females had ever used e-cigarettes. E-cigarette use was significantly associated with current smoking, snus (a moist powder tobacco product originating in Sweden) use, water pipe use, intensive alcohol consumption, and narcotics and also with psychosocial conditions related to home and parents, peers, and school. The prevalence of ever e-cigarette use was high among adolescents attending both grades. E-cigarette use was most strongly associated with health-related lifestyles. It was also associated with psychosocial factors such as study difficulties, school stress, problems talking with parents, and generalized trust. Copyright © 2017 The Royal Society for Public Health.

    Purpose Smoking is a leading cause of cancer, and most smokers begin during adolescence. We examined the proportion of adolescents exposed to pro-tobacco advertising and assessed the association between this exposure and susceptibility to smoking. Methods Data from the 2011 National Youth Tobacco Survey were used to calculate the proportion of susceptible middle school (MS) and high school (HS) students exposed to pro-tobacco advertisements through stores, magazines, and the Internet. Following previous work, susceptibility to smoking cigarettes was defined as “never smoked but open to trying cigarettes.” Results In 2011, 81.5% of MS students and 86.9% of HS students were exposed to tobacco advertisements in stores; 48.2% of MS students and 54.0% of HS students were exposed to such advertising in magazines. Exposure to tobacco advertisements on the Internet was similar for MS (40.8%) and HS students (40.2%). Of those surveyed, 22.5% of MS students and 24.2% of HS students were susceptible to trying cigarettes. Exposure to magazine advertising declined from 71.8% in 2000 to 46.1% in 2009 among susceptible MS students; however, exposure increased to 55.4% in 2011. Tobacco advertising seen through the Internet among susceptible HS students increased from 25.9% in 2000 to 44.7% in 2011. Conclusions Adolescents continue to be exposed to pro-tobacco advertisements. Adolescents susceptible to smoking are more likely to report exposure to pro-tobacco advertisements. In addition to continued monitoring, more effective interventions to eliminate youth exposure to pro-tobacco marketing are needed. PMID:23601611

    This article deals with an important topic (youth smoking) and makes a contribution to the literature by validating existing research and extending our understanding of smoking resistance strategies. This study classified adolescent reports of their responses to cigarette smoking offers utilizing four drug refusal strategies of refuse, explain, avoid, and leave (REAL) and explored how personality factors explain adolescents' use of cigarette refusal strategies. Participants were predominantly Hispanic junior high students (6th-8th grades) from schools in the Northeast United States who participated in a survey design (N = 260). The strategy of explain was reported most frequently for initial and follow-up smoking offers. Adolescents with a greater number of friends who smoked were more likely to use the avoid strategy for initial smoking offers. Sensation seeking was positively related to the use of leave and avoid strategies for initial smoking offers and leave strategy for follow-up smoking offers. No association was found between self-esteem and use of smoking refusal strategies. Implications and directions for future research are discussed.

    The vast majority of drug users smoke cigarettes. Most use marijuana and no other illicit drug. We analyzed adult responses to the 1997 NHSDA (n = 16,661) to explore relationships between marijuana use and cigarette smoking. Multivariate analyses controlled for other illicit drug use and other potential covariates. Nearly three-quarters of current marijuana users (74%) smoked cigarettes. Compared to nonusers, the adjusted odds of being a smoker were 5.43 for current marijuana users, 3.58 for past year marijuana users, and 2.02 for former marijuana users. Odds for cigarette smoking among current poly-drug users, compared to nonusers, were 2.3 to 1. Level of cigarette smoking was directly associated with frequency of marijuana use. Nationwide, an estimated 7 million adults smoke both substances and are at increased risk for respiratory illnesses and mortality. Cigarette smoking is a major co-morbidity of marijuana use and smoking cessation should be addressed among marijuana users in addition to their other illicit drug involvement.

    Forty-two male cigarette smokers, age 18 to 44, were randomly assigned to high-nicotine, low-nicotine, or control groups in a study relating cigarette smoking to sexual response. Subjects watched erotic film segments while their penile diameters, heart rates, and finger pulse amplitudes were continuously recorded by a polygraph. Subjects in the smoking groups smoked relatively high-nicotine (.9 mg) or very low-nicotine (.002 mg) cigarettes prior to watching the last two films, while control subjects ate candy. Smoking two high-nicotine cigarettes in immediate succession significantly decreased the rate of penile diameter change relative to the other conditions. These effects were not seen after a single cigarette was smoked. High-nicotine cigarettes caused significantly more vasoconstriction and heart rate increase than did low-nicotine cigarettes, which did not differ from control conditions.

    This experiment tested whether introducing graphic antitobacco posters at point-of-sale (POS) had any effect on adolescents' susceptibility to future cigarette smoking and whether these effects were moderated by adolescents' baseline risk of cigarette smoking. The study was conducted in the RAND StoreLab, a life-sized replica of a convenience store that was developed to experimentally evaluate how changing aspects of tobacco advertising displays in retail POS environments influence tobacco use risk and behavior during simulated shopping experiences. In this study, 441 adolescents were randomized to one of the four conditions in a 2 (graphic antismoking poster placed near the tobacco power wall: no, yes) × 2 (graphic antismoking poster placed near the cash register: no, yes) experimental design. The outcome of interest was susceptibility to future cigarette smoking. The addition of antismoking posters at POS led to a significant increase in future smoking susceptibility among those adolescents who already were at high risk for smoking in the future (p < .045). The introduction of graphic antismoking posters had no impact on committed never smokers, regardless of poster location; never smokers' susceptibility to future smoking was uniformly low across experimental conditions. Introducing graphic antismoking posters at POS may have the unintended effect of further increasing cigarette smoking susceptibility among adolescents already at risk. © The Author(s) 2017.

    Summary Cigarette smoking is a leading cause of preventable morbidity and mortality in the United States. Although public policies have resulted in a decreased number of new smokers, smoking rates remain stubbornly high in certain demographics with 20% of all American middle aged men smoking. In addition to the well-established harmful effects of smoking (i.e coronary artery disease and lung cancer), the past three decades have led to a compendium of evidence being compiled into the development of a relationship between cigarette smoking and erectile dysfunction. The main physiological mechanism that appears to be affected includes the nitric oxide signal transduction pathway. This review details the recent literature linking cigarette smoking to erectile dysfunction, epidemiological associations, dose-dependency and the effects of smoking cessation on improving erectile quality.

    2018-01-01

    Cigarette cravings, especially those in response to environmental stressors and other smoking-related triggers (e.g., passing by a favorite smoking spot), are important contributors to smoking behavior and relapse. Previous studies have demonstrated significant individual differences in such cravings. This study explores the possibility that attitudes about smoking can influence the experience of cigarette craving. Consistent with classical theories of the links between cognition and motivation, we predicted that smokers who exhibit more favorable attitudes towards smoking would have greater cravings. Daily smokers (n=103, mean age=41.8years, 33% female) were instructed to imagine smoking, stress, and neutral scenarios. Cravings were measured prior to and after each exposure. Participants also completed an abridged version of the Smoking Consequence Questionnaire (SCQ) that had them rate the: 1) desirability and 2) likelihood, for eighteen separate negative smoking consequences (e.g., "The more I smoke, the more I risk my health", "People will think less of me if they see me smoking"). Findings revealed that favorable attitudes about the consequences of smoking, as measured by the SCQ-desirability index, significantly predicted cigarette cravings. Findings suggest that individual attitudes toward smoking may play an important role in better understanding cigarette cravings, which may ultimately help identify targets for more efficient and effective cognitive/attitude-based interventions for smoking cessation.

    2014-11-01

    Smoking causes around 100,000 deaths each year in the UK, and is the leading cause of preventable disease and early mortality. Smoking cessation remains difficult and existing licensed treatments have limited success. Nicotine addiction is thought to be one of the primary reasons that smokers find it so hard to give up, and earlier this year DTB reviewed the effects of nicotine on health. Electronic cigarettes (e-cigarettes) are nicotine delivery devices that aim to mimic the process of smoking but avoid exposing the user to some of the harmful components of traditional cigarettes. However, the increase in the use of e-cigarettes and their potential use as an aid to smoking cessation has been subject to much debate. In this article we consider the regulatory and safety issues associated with the use of e-cigarettes, and their efficacy in smoking cessation and reduction.

    2012-01-01

    Introduction: Several cross-sectional studies have examined factors associated with support for tobacco control policies. The current study utilized a longitudinal design to test smoking status and attitude toward smoking measured in adolescence as prospective predictors of support for tobacco control policies measured in adulthood. Methods: Participants (N = 4,834) were from a longitudinal study of a Midwestern community-based sample. Hierarchical multiple regression analyses tested adolescent smoking status and attitude toward smoking as prospective predictors (after controlling for sociodemographic factors, adult smoking status, and adult attitude toward smoking) of support for regulation of smoking in public places, discussion of the dangers of smoking in public schools, prohibiting smoking in bars, eliminating smoking on television and in movies, prohibiting smoking in restaurants, and increasing taxes on cigarettes. Results: Participants who smoked during adolescence demonstrated more support for discussion of the dangers of smoking in public schools and less support for increasing taxes on cigarettes but only among those who smoked as adults. Those with more positive attitudes toward smoking during adolescence demonstrated less support as adults for prohibiting smoking in bars and eliminating smoking on television and in movies. Moreover, a significant interaction indicated that those with more positive attitudes toward smoking as adolescents demonstrated less support as adults for prohibiting smoking in restaurants, but only if they became parents as adults. Conclusions: This study’s findings suggest that interventions designed to deter adolescent smoking may have future benefits in increasing support for tobacco control policies. PMID:22193576

    Mandating a reduction in the nicotine content of cigarettes to a minimally addictive level could dramatically reduce smoking rates in the US. However, little is known about the effects of reduced nicotine content cigarettes in adolescents. Following overnight abstinence, adolescent daily smokers (ages 15-19, n = 50) reported on their craving, withdrawal, and positive and negative affect pre- and post- ad lib smoking of one cigarette containing varying nicotine content (15.8, 5.2, 1.3 and 0.4 mg/g of tobacco) in the laboratory and reported their subjective evaluations of each cigarette. Carbon monoxide (CO) boost from pre- to post-cigarette was calculated to determine if lower-nicotine cigarettes led to differential acute changes in toxicant exposure. All four nicotine cigarette types significantly reduced abstinence-induced craving, withdrawal, and negative affect (all p's < .05). Mixed models evaluating the effect of nicotine content, with nicotine dependence level and gender included as covariates, revealed a significant effect of nicotine content on craving and subjective evaluations: higher nicotine content resulted in greater reductions in craving and increases in both positive and negative subjective evaluations. There were no significant effects of nicotine dose on withdrawal symptoms, negative affect, or CO boost. These results suggest that lower nicotine cigarettes might result in reduced abuse liability compared to higher nicotine content cigarettes due to reduced positive subjective effects, while still reducing withdrawal, in adolescents. These results highlight the potential feasibility of this policy approach and support continued research on how a nicotine reduction policy may affect adolescent smoking patterns.

    Much attention has been directed towards the possible effects of e-cigarette advertisements on adolescent never smokers. However, e-cigarette advertising may also influence perceptions and behaviours of adult smokers. The aim of our study was to examine whether noticing e-cigarette advertisements is associated with current use of e-cigarettes, disapproval of smoking, quit smoking attempts, and quit smoking success. We used longitudinal data from two survey waves of the ITC Netherlands Survey among smokers aged 16 years and older (n=1198). Respondents were asked whether they noticed e-cigarettes being advertised on television, on the radio, and in newspapers or magazines in the previous 6 months. There was a significant increase in noticing e-cigarette advertisements between 2013 (13.3%) and 2014 (36.0%), across all media. The largest increase was for television advertisements. There was also a substantial increase in current use of e-cigarettes (from 3.1% to 13.3%), but this was not related to noticing advertisements in traditional media (OR=0.99, p=0.937). Noticing advertisements was bivariately associated with more disapproval of smoking (Beta=0.05, p=0.019) and with a higher likelihood of attempting to quit smoking (OR=1.37, p=0.038), but these associations did not reach significance in multivariate analyses. There was no significant association between noticing advertisements and quit smoking success in either the bivariate or multivariate regression analysis (OR=0.92, p=0.807). Noticing e-cigarette advertisements increased sharply in the Netherlands between 2013 and 2014 along with increased e-cigarette use, but the two appear unrelated. The advertisements did not seem to have adverse effects on disapproval of smoking and smoking cessation. Copyright © 2015 Elsevier B.V. All rights reserved.

Ninth-grade African American adolescents (n = 566) were interviewed in Year 1 and then were subsequently interviewed annually for 3 additional years. Five trajectories of cigarette smokers were identified: abstainers,…

    To assess whether exposure to movie smoking is associated with cigarette smoking among Argentinian adolescents. A school-based longitudinal study involving 33 secondary schools in Argentina was performed. The sample included 2502 never smokers (average age at entry = 12.5 years), 1700 (67.9%) of whom completed follow-up surveys 17 months later. Exposure to the top 100 highest-grossing films for each year between 2009 and 2013 was assessed by content-coding films for tobacco and then by asking adolescents whether they had seen each of 50 titles, randomly selected from the larger pool, then parsing exposure into tertiles. Logistic regression models estimated aOR for the following transitions: nonsusceptible to susceptible never smoker, never smoker to ever smoker, and never smoker to current smoking (last 30 days). At follow-up, 34.4% of nonsusceptible never smokers became susceptible, 24.1% reported having tried smoking, and 9.4% were current smokers. Most exposure to movie smoking was from US-produced films (average 60.3 minutes compared with only 3.4 minutes from Argentine films). Greater exposure to smoking in movies was significantly associated with increased odds of becoming susceptible (aOR first vs third tertile  1.77, 95% CI 1.30-2.41), of trying smoking (aOR first vs third tertile  1.54, 1.14-2.08), and marginally associated with current smoking (AOR first vs third tertile  1.54, 0.99-2.40). Exposure to smoking in US- or Argentine-produced films had similar associations. In Argentina, exposure to smoking in the movies predicted future smoking transitions among early adolescents, with most exposure coming from viewing US movies. Copyright © 2016 Elsevier Inc.

    Objective To assess whether exposure to movie smoking is associated with cigarette smoking among Argentinian adolescents. Study design School-based longitudinal study involving 33 secondary schools in Argentina. The sample included 2502 never smokers (average age at entry =12.5y), 1,700 (67.9%) of whom completed follow-up surveys 17 months later. Exposure to the top 100 grossing films for each year between 2009 and 2013 was assessed by content-coding films for tobacco, and then asking adolescents whether they had seen each of 50 titles, randomly selected from the larger pool, then parsing exposure into tertiles. Logistic regression models estimated adjusted odds ratio (AOR) for the following transitions: non-susceptible to susceptible never smoker, never smoker to ever smoker, and never smoker to current smoking (last 30 days). Results At follow-up, 34.4% of non-susceptible never smokers became susceptible, 24.1% reported having tried smoking, and 9.6% were current smokers. Most exposure to movie smoking was from US-produced films (average 60.3 minutes compared with only 3.4 minutes from Argentine films). Higher exposure to smoking in movies was significantly associated with increased odds of becoming susceptible (AOR1st vs 3rd tertile = 1.77, 95% confidence interval 1.30–2.41), of trying smoking (AOR1st vs 3rd tertile = 1.54, 1.14–2.08), and marginally associated with current smoking (AOR1st vs 3rd tertile = 1.54, 0.99–2.40).

    Electronic cigarettes (e-cigarettes) have been steadily increasing in popularity among smokers, most of whom report using them to quit smoking. This study systematically reviews the current literature on the effectiveness of e-cigarettes as cessation aids. We searched PubMed, MEDLINE, PsycINFO, CINAHL, ERIC, ROVER, Scopus, ISI Web of Science, Cochrane Library, the Ontario Tobacco Research Unit (OTRU) library catalogue, and various gray literature sources. We included all English-language, empirical quantitative and qualitative papers that investigated primary cessation outcomes (smoking abstinence or reduction) or secondary outcomes (abstinence-related withdrawal symptoms and craving reductions) and were published on or before February 1, 2016. Literature searches identified 2855 references. After removing duplicates and screening for eligibility, 62 relevant references were reviewed and appraised. In accordance with the GRADE system, the quality of the evidence in support of e-cigarettes' effectiveness in helping smokers quit was assessed as very low to low, and the evidence on smoking reduction was assessed as very low to moderate. The majority of included studies found that e-cigarettes, especially second-generation types, could alleviate smoking withdrawal symptoms and cravings in laboratory settings. While the majority of studies demonstrate a positive relationship between e-cigarette use and smoking cessation, the evidence remains inconclusive due to the low quality of the research published to date. Well-designed randomized controlled trials and longitudinal, population studies are needed to further elucidate the role of e-cigarettes in smoking cessation. This is the most comprehensive systematic evidence review to examine the relationship between e-cigarette use and smoking cessation among smokers. This review offers balanced and rigorous qualitative and quantitative analyses of published evidence on the effectiveness of e-cigarette use for smoking

    Raising cigarette prices through taxation is an important policy approach to reduce smoking. Yet, cigarette price increases may not be equally effective in all subpopulations of smokers. To examine differing effects of state cigarette price changes with individual changes in smoking among smokers of different intensity levels. Data were derived from the National Epidemiologic Survey on Alcohol and Related Conditions, a nationally representative sample of US adults originally interviewed in 2001-2002 (Wave 1) and re-interviewed in 2004-2005 (Wave 2): 34 653 were re-interviewed in Wave 2, and 7068 smokers defined at Wave 1 were included in our study. Mixed effects linear regression models were used to assess whether the effects of changes in state cigarette prices on changes in daily smoking behaviour differed by level of daily smoking. In the multivariable model, there was a significant interaction between change in price per pack of cigarettes from Wave 1 to Wave 2 and the number of cigarettes smoked per day (p=0.044). The more cigarettes smoked per day at baseline, the more responsive the smokers were to increases in price per pack of cigarettes (ie, number of cigarettes smoked per day was reduced in response to price increases). Our findings that heavier smokers successfully and substantially reduced their cigarette smoking behaviours in response to state cigarette price increases provide fresh insight to the evidence on the effectiveness of higher cigarette prices in reducing smoking.

    Cigarette smoking (CS) continues to be a major health hazard, and it contributes significantly to cardiovascular morbidity and mortality. Cigarette smoking impacts all phases of atherosclerosis from endothelial dysfunction to acute clinical events, the latter being largely thrombotic. Both active and passive (environmental) cigarette smoke exposure predispose to cardiovascular events. Whether there is a distinct direct dose-dependent correlation between cigarette smoke exposure and risk is debatable, as some recent experimental clinical studies have shown a non-linear relation to cigarette smoke exposure. The exact toxic components of cigarette smoke and the mechanisms involved in CS-related cardiovascular dysfunction are largely unknown, but CS increases inflammation, thrombosis, and oxidation of low-density lipoprotein cholesterol. Recent experimental and clinical data support the hypothesis that cigarette smoke exposure increases oxidative stress as a potential mechanism for initiating cardiovascular dysfunction.

    We aimed to identify developmental trajectories of cigarette use and risk factors associated with the distinct developmental courses of smoking in Chinese early adolescents from age 12 to 16 years. Analysis was conducted with secondary data from a longitudinal, prospective cohort of 3,521 Chinese adolescents randomly selected from 4 rural and 7 urban middle schools in Wuhan, China. A group-based growth mixture modeling approach was adopted to identify developmental trajectories of cigarette use. Multilayered intrapersonal (e.g., attitudes toward smoking) and interpersonal (e.g., parental smoking and perceived parental disapproval of smoking) risk factors selected from an ecological perspective were prospectively linked to the identified patterns of smoking trajectory. Three trajectory patterns were identified from the whole cohort: nonsmokers (48.7%), stable light/occasional smokers (48.6%), and accelerating smokers (2.7%). After adjustments for gender, urban residence, and family socioeconomic status, adolescents with higher levels of problems in parent-child relationships and family disharmony, higher perceived norms of peer smoking, higher proportion of good friend smoking, having more troubles with teachers, poorer academic performance, and reporting more frequent depressive symptoms were significantly more likely to be in the trajectory group of either stable light/occasional smokers or accelerating smokers than in the group of nonsmokers. The probability of being in the accelerating smoking trajectory group was positively and significantly related to parental smoking and lack of school bonding. Study findings help to advance knowledge of the distinct developmental courses of smoking behavior and their associations with multilayered risk factors among Chinese early adolescents.

    Purpose There is a dearth of research into whether ENDS promote acceptance of cigarette smoking. Therefore, we aimed to assess the association between ENDS exposure, acceptance of cigarette smoking, and susceptibility to cigarette smoking. Methods Data from the 2014 Florida Youth Tobacco Survey with a state-representative sample of middle and high school students (n=68928) were analyzed. Own ENDS use, exposure to ENDS advertising, and living with ENDS users, acceptance of adult cigarette smoking, demographics and known predictors of cigarette smoking were assessed. Susceptibility to cigarette smoking was assessed among never smokers. Weighted multiple logistic regression models and mediation analyses were conducted, stratifying by middle/high school and never/ever smoking. Analyses were conducted in 2016. Results Own ENDS use, exposure to ENDS advertising, and living with ENDS users were associated with acceptance of adult cigarette smoking even among never smokers, after accounting for covariates (p<0.05). In a mediation analysis, own ENDS use, exposure to ENDS advertising, and living with ENDS users were indirectly associated with susceptibility to cigarette smoking among never smokers through acceptance of adult cigarette smoking (p<0.05). Conclusions Youth ENDS exposure may contribute to normalizing adult smoking, and may in turn heighten susceptibility to cigarette smoking. If confirmed by longitudinal studies, these findings suggest that ENDS policy interventions may help prevent youth cigarette smoking. PMID:28159423

    Cigarette smoking is a serious health problem throughout the world, with a complicated and not totally clear bio-effect. In this study, erythrocytes were obtained from healthy male volunteers aged 22 ± 2 years and, the possible effects of three cigarette smoking rates namely 10, 15 and 20 cigarette/day on erythrocytes membrane characteristics were examined by Fourier transform infrared spectroscopy (FTIR). The results of this study indicate many smoking-dependent variations on erythrocytes membrane without an obvious dose-response relationship. There was disruption in the acyl chain packing; changes in membrane order and phases as well as membrane proteins becoming more folded. These physico-chemical changes should have an impact on the function of erythrocytes and may explain the complex interaction of cigarette smoke mainstream with erythrocyte membrane and to some extent clarify the pathological processes associated with cigarette smoking.

    A broadly mandated reduction of the nicotine content (RNC) of cigarettes has been proposed in the United States to reduce the addictiveness of cigarettes, to prevent new smokers from becoming addicted and to facilitate quitting in established smokers. The primary aim of this study was to determine whether following 7 months of smoking very low nicotine content cigarettes (VLNC), and then returning to their own cigarettes, smokers would demonstrate persistently reduced nicotine intake compared with baseline or quit smoking. In a community-based clinic 135 smokers not interested in quitting were randomized to one of two groups. A research group smoked their usual brand of cigarettes, followed by five types of research cigarettes with progressively lower nicotine content, each for 1 month, followed by 6 months at the lowest nicotine level (0.5 mg/cigarette) (53 subjects) and then 12 months with no intervention (30 subjects completed). A control group smoked their usual brand for the same period of time (50 subjects at 6 months, 38 completed). Smoking behavior, biomarkers of nicotine intake and smoke toxicant exposure were measured. After 7 months smoking VLNC, nicotine intake remained below baseline (plasma cotinine 149 versus 250 ng/ml, P<0.005) with no significant change in cigarettes per day or expired carbon monoxide (CO). During the 12-month follow-up, cotinine levels in RNC smokers rose to baseline levels and to those of control smokers. Quit rates among RNC smokers were very low [7.5 versus 2% in controls, not significant). In smokers not interested in quitting, reducing the nicotine content in cigarettes over 12 months does not appear to result in extinction of nicotine dependence, assessed by persistently reduced nicotine intake or quitting smoking over the subsequent 12 months. © 2015 Society for the Study of Addiction.

    The present study examined effects of current and past regular cigarette smoking in young adult subjects. One hundred and twelve 17-21-year-old subjects, assessed since infancy, were evaluated using a battery of neurocognitive tests for which commensurate measures were obtained at 9-12 years of age, prior to the initiation of regular smoking. Smokers, determined by urinalysis and self-report, were categorized as heavy (>9 cigarettes per day) and light (<9 cigarettes per day) current smokers and former smokers, the latter having smoked cigarettes regularly in the past but not for at least 6 months. A third of the subjects were currently smoking cigarettes regularly with half of these being heavy smokers. Among former smokers, the average duration of smoking was slightly less than 2 years. Overall IQ, memory, processing speed, vocabulary, attention and abstract reasoning were the primary outcomes with comparisons being made between each of the three user groups and a control group who never smoked regularly. After accounting for potentially confounding factors including clinical assessment, marihuana use and pre-drug performance in the relevant cognitive domain, current regular smokers did significantly worse than non-smokers in a variety of cognitive areas predicated upon verbal/auditory competence including receptive and expressive vocabulary, oral arithmetic, and auditory memory. This impact of current smoking appears to behave in a dose-response and duration-related fashion. In contrast, former smokers differed from the non-smokers only in the arithmetic task. These results suggest that regular smoking during early adulthood is associated with cognitive impairments in selected domains and that these deficits may be reversed upon cessation. Together, the findings add to the body of evidence to be used in persuading adolescents and young adults against the initiation of smoking and, if currently smoking, the advantages of stopping.

    African Americans are disproportionately exposed to cigarette advertisements, particularly for menthol brands. Tobacco industry documents outline strategic efforts to promote menthol cigarettes to African Americans at the point of sale, and studies have observed more outdoor and retail menthol advertisements in neighborhoods with more African-American residents. Little research has been conducted to examine the effect of this target marketing on adolescents' recognition of cigarette brand advertising and on smoking uptake. To our knowledge, this is the first study to examine racial differences in brand recognition and to assess the prospective relationship between brand recognition and smoking uptake. School-based surveys assessing tobacco use and environmental and social influences to smoke were administered to 6th through 9th graders (ages 11 to 15) in an urban and racially diverse California school district. The primary outcome for the cross-sectional analysis (n = 2,589) was brand recognition, measured by students' identification of masked tobacco advertisements from the point of sale. The primary outcome for the longitudinal analysis (n = 1,179) was progression from never to ever smoking within 12 months. At baseline, 52% of students recognized the Camel brand, 36% Marlboro, and 32% Newport. African-American students were three times more likely than others to recognize Newport (OR = 3.03, CI = 2.45, 3.74, p < 0.01) and less likely than others to recognize Marlboro (OR = 0.60, CI = 0.48, 0.73, p < 0.01). At follow-up, 17% of never smokers reported trying smoking. In this racially diverse sample, brand recognition of Camel and Marlboro did not predict smoking initiation. Regardless of race, students who recognized the Newport brand at baseline were more likely to initiate smoking at follow-up (OR = 1.49, CI = 1.04, 2.15, p < 0.05) after adjusting for shopping frequency and other risk factors.

    Prenatal exposure to maternal cigarette smoking (PEMCS) may affect brain development and behavior in adolescent offspring. To evaluate the involvement of the orbitofrontal cortex (OFC) in mediating the relationship between PEMCS and substance use. Cross-sectional analyses from the Saguenay Youth Study aimed at evaluating the effects of PEMCS on brain development and behavior among adolescents. Nonexposed adolescents were matched with adolescents exposed prenatally to cigarette smoking by maternal educational level. A French Canadian founder population of the Saguenay-Lac-Saint-Jean region of Quebec, Canada. The behavioral data set included 597 adolescents (275 sibships; 12-18 years of age), half of whom were exposed in utero to maternal cigarette smoking. Analysis of cortical thickness and genotyping were performed using available data from 314 adolescents. The likelihood of substance use was assessed with the Diagnostic Interview Schedule for Children Predictive Scales. The number of different drugs tried by each adolescent was assessed using another questionnaire. Thickness of the OFC was estimated from T1-weighted magnetic resonance images using FreeSurfer software. Prenatal exposure to maternal cigarette smoking is associated with an increased likelihood of substance use. Among exposed adolescents, the likelihood of drug experimentation correlates with the degree of OFC thinning. In nonexposed adolescents, the thickness of the OFC increases as a function of the number of drugs tried. The latter effect is moderated by a brain-derived neurotrophic factor (BDNF) genotype (Val66Met). We speculate that PEMCS interferes with the development of the OFC and, in turn, increases the likelihood of drug use among adolescents. In contrast, we suggest that, among nonexposed adolescents, drug experimentation influences the OFC thickness via processes akin to experience-induced plasticity.

    Research has shown that smoking menthol cigarettes induces smoking initiation and hinders cessation efforts especially among youth. The objective of this paper is to examine the association between menthol cigarette smoking and substance use among adolescent students in Canada. A nationally representative cross-sectional sample of 4466 Canadian students in grades 7 to 12 from the 2010-2011 Youth Smoking Survey is analyzed. A bivariate probit model is used jointly to examine the association of menthol smoking status with binge drinking and marijuana use. 32% of the current smokers in grades 7 to 12 smoke mentholated cigarettes, 73% are binge drinkers and 79% use marijuana. Results of the bivariate probit regression analysis, controlling for other covariates, show statistically significant differences in the likelihood of binge drinking and marijuana use between menthol and non-menthol smokers. Menthol cigarette smokers are 6% (ME=0.06, 95% CI=0.03-0.09) more likely to binge drink and 7% (ME=0.07, 95% CI=0.05-0.10) more likely to use marijuana. Smoking menthol cigarettes is associated with a higher likelihood of binge drinking and marijuana use among Canadian adolescents. Banning menthol in cigarettes may be beneficial to public health.

    Despite increasing popularity, health consequences of vaping (smoking electronic cigarettes, e-cigarettes) are poorly described. Few studies suggest that vaping has less deleterious effects on lung function than smoking conventional cigarettes. One large study found that e-cigarettes were as efficient as nicotine patches in smoking cessation. The long-term consequences of vaping are however unknown and while some experts are open towards e-cigarettes as a safer way of satisfying nicotine addiction, others worry that vaping in addition to presenting a health hazard may lead to an increased number of smokers of conventional cigarettes.

    Cigarette smoking is a major preventable cause of morbidity and mortality worldwide. Most adult smokers start smoking regularly some time before 18 years of age. The aim of this study was to determine the age at which children begin cigarette smoking, to study the environmental factors that influence children to smoke, and to understand the reasons why children smoke. The results of this study may help lead to the development of more effective smoking prevention programs. We carried out a cross-sectional survey of all students in grades 6 to 11 (ages: 11 to 17 years) in two high schools in the Jerusalem area, using an anonymous self-completion questionnaire. The students were asked questions regarding the age at which they began smoking, initiation, their smoking habits, their reasons for smoking, and their views on children who smoke. In addition, they were asked about the smoking status of their parents, siblings, and friends. Finally they were asked about the health hazards of smoking. Of the 847 students who answered the questionnaire, 35% stated that they had smoked at least once and 14% stated that they were currently smoking. The percentage of students who were currently smoking increased gradually with age to 36%. There was a sharp increase in experimental smoking after seventh grade (ages 12 to 13 years). Having a friend who smoked substantially increased the likelihood of smoking, whereas parental smoking or having a sibling who smoked did not increase the likelihood of smoking. The most common reason for starting to smoke was "to try something new" (55%). There was a significant difference between the views of students with different smoking statuses regarding children who smoke: nonsmoking children associated more negative characteristics to smoking. All of the children studied were well aware of the health hazards of cigarette smoking. Smoking is highly prevalent among schoolchildren in Jerusalem. The increase in the rate of smoking at the age of 12

    To test movie exposure and television use as predictors of smoking initiation among white and black adolescents who had never smoked cigarettes. Survey research using audio computer-assisted self-interviews at baseline and at 2-year follow-up (2002-2004). Participants' homes located in central North Carolina. A sample of 735 12- to 14-year-old adolescents drawn from 14 public middle schools. Frequency of exposure to movies rated R, PG-13, PG, or G; frequency, location, and parental oversight of television viewing. Initiation of smoking, indicated by the first occasion of puffing on a cigarette. Among white adolescents, high relative exposure to R-rated movies predicted a significantly greater likelihood of smoking initiation at follow-up, and private access to television during early adolescence, indicated by having a bedroom television, was also a significant independent predictor of smoking initiation at follow-up. No significant associations were observed between any movie-exposure or television-use variables and likelihood of smoking among black adolescents. Indicators of risky media use were associated with a significantly greater likelihood of smoking for white but not for black adolescents. These results diverge strongly from past results, which have indicated that all adolescents, regardless of race or place of residence, have a higher risk of smoking initiation as their exposure to movie smoking increases. Research is needed to identify the antecedents of risky media use and to understand how audience attributes, including race and other factors, moderate the effects of risky media use on health-related behaviors.

    Introduction: This paper reports on the prevalence, factors and patterns of cigarette smoking among rural California American Indian (AI) adults. Methods: Thirteen Indian health clinic registries formed the random household survey sampling frame (N = 457). Measures included socio-demographics, age at smoking initiation, intention to quit, smoking usage, smoking during pregnancy, health effects of smoking, suicide attempts or ideation, history of physical abuse, neglect and the role of the environment (smoking at home and at work). Statistical tests included Chi Square and Fisher’s Exact test, as well as multiple logistic regression analysis among never, former, and current smokers. Results: Findings confirm high smoking prevalence among male and female participants (44% and 37% respectively). American Indians begin smoking in early adolescence (age 14.7). Also, 65% of current smokers are less than 50% Indian blood and 76% of current smokers have no intention to quit smoking. Current and former smokers are statistically more likely to report having suicidal ideation than those who never smoked. Current smokers also report being neglected and physically abused in childhood and adolescence, are statistically more likely to smoke ½ pack or less (39% vs. 10% who smoke 1+ pack), smoke during pregnancy, and have others who smoke in the house compared with former and never smokers. Conclusion: Understanding the factors associated with smoking will help to bring about policy changes and more effective programs to address the problem of high smoking rates among American Indians.

    Data derived from four major prospective epidemiological studies in the U.S. and Britain indicate that persistent cigarette smoking in later life carries an appreciable hazard. In two of these studies men aged over 65 years who smoked cigarettes had a significantly higher mortality from coronary heart disease than men who had ceased to smoke cigarettes, and in all four studies their overall mortality was significantly higher than that of ex-smokers. At 65 to 74 years the overall mortality of men still smoking cigarettes was higher by 24 percent or more than that of ex-smokers, and at 75 to 84 yearsmore » it was higher by 12 to 18 percent. The absolute difference in overall mortality was 9 to 13/1000 person-years in both age-groups. A comparison of data on men who had given up smoking at different ages suggests that while the benefit is greater if smoking is stopped earlier in life, men in their sixties and (especially in the case of heavy smokers) their early seventies may still increase their longevity by giving up smoking cigarettes.« less

    To assess the association between exposure to movie smoking and established adolescent smoking. Longitudinal survey of a representative US adolescent sample. Adolescents were surveyed by telephone in their homes. Sixty-five hundred twenty-two US adolescents aged 10 to 14 years at baseline, resurveyed at 8 months (8M) (n = 5503), 16 months (16M) (n = 5019), and 24 months (24M) (n = 4575). Main Exposure Exposure to smoking in 532 box-office hits released in the 5 years prior to the baseline survey. Outcome Measure Established smoking (having smoked more than 100 cigarettes during lifetime). Of 108 incident established smokers with data at the 24M survey, 85% were current (30-day smokers) and 83% endorsed at least 1 addiction symptom. Established smoking incidence was 7.4, 15.8, and 19.7 per 1000 person-years of observation for the baseline-to-8M, 8M-to-16M, and 16M-to-24M observation periods, respectively. In a multivariate survival model, risk of established smoking was predicted by baseline exposure to smoking in movies with an adjusted overall hazard ratio of 2.04 (95% confidence interval, 1.01-4.12) for teens in the 95th percentile of movie-smoking exposure compared with the 5th percentile. This effect was independent of age; parent, sibling, or friend smoking; and sensation seeking. Teens low on sensation seeking were more responsive to the movie-smoking effect (hazard ratio, 12.7; 95% confidence interval, 2.0-80.6) compared with teens who were high on sensation seeking (hazard ratio, 1.01; 95% confidence interval, 0.4-2.6). In this national US adolescent sample, exposure to smoking in movies predicted risk of becoming an established smoker, an outcome linked with adult dependent smoking and its associated morbidity and mortality.

    Electronic cigarettes are quite a new potential source of nicotine addiction among youth. More research is needed, particularly on e-liquid use and socioeconomic factors as potential determinants. We studied changes from 2013 to 2015 in adolescent e-cigarette awareness and ever-use, types of e-liquids, and determinants in Finland. In 2015, we studied weekly use and reasons for ever-use. Data were from two national surveys of 12-18-year-old Finns (2013, n = 3535, response rate 38%; 2015, n = 6698, 41%). Descriptive statistics and logistic regression analysis were used. Awareness and ever-use of e-cigarettes increased significantly from 2013 to 2015 in all age and gender groups. Ever-use increased from 17.4% to 25%, with half having tried nicotine e-liquids. In 2015, weekly use was rare (1.5%). Daily cigarette smoking was the strongest determinant (OR 51.75; 95% CI 38.18-70.14) for e-cigarette ever-use, as for e-cigarette weekly use, but smoking experimentation and ever-use of snus (Swedish type moist snuff) and waterpipes alongside parental smoking and poor academic achievement also increased the odds for ever-use. The most common reason behind e-cigarette ever-use was the desire to try something new. To conclude, adolescent e-cigarette ever-use is increasing, and also among never-smokers. Tobacco-related factors are stronger determinants for e-cigarette use than socioeconomic factors.

    There is growing evidence that an adolescent's decision to try cigarettes is influenced by level of exposure to movies in which smoking is portrayed. Less is known about how ethnicity affects this process. We examined whether acculturation and/or country of birth influence the relationship between exposure to smoking imagery in the movies and experimenting with cigarettes among Mexican origin youth. We prospectively followed 1,328 Mexican origin adolescents ages 11 to 13 years at baseline. We assessed which of 50 movies (randomly selected from a pool of 250 popular contemporary movies released from 1999 to 2004 and content analyzed for smoking) adolescents had seen. Smoking behavior was assessed at baseline and at 6-month intervals over 24 months. Ten percent of the adolescents had experimented at baseline; 17% tried subsequently. Multivariate analyses revealed, as exposure to smoking imagery in the movies increased, the chances of having ever experimented [adjusted odds ratio (AOR) = 1.27; 95% confidence interval (CI), 1.10-1.48] and of being a new experimenter (AOR = 1.19; 95% CI, 1.01-1.40) increased, equivalent to a 4.2% increased risk of ever and a 3.0% increased risk of new experimenting for each additional quartile of movie exposure. This effect was moderated by country of birth. For Mexican-born youth, exposure to smoking imagery in the movies was the strongest independent predictor of new experimentation (AOR = 1.52; 95% CI, 1.14-2.05). For U.S.-born youth, we observed a ceiling effect: the percent of experimenters increased with increasing exposure, and then flattened. Among Mexican-born youth, exposure to smoking imagery in the movies may be an important part of the acculturation process associated with smoking initiation.

    We sought to describe long-term adolescent and young adult smoking trends and patterns. We analyzed adolescent data from Monitoring the Future, 1976 to 2005, and young adult (aged 18-24 years) data from the National Health Interview Survey, 1974 to 2005, overall and in subpopulations to identify trends in current cigarette smoking prevalence. Five metapatterns emerged: we found (1) a large increase and subsequent decrease in overall smoking over the past 15 years, (2) a steep decline in smoking among Blacks through the early 1990s, (3) a gender gap reversal among older adolescents and young adults who smoked over the past 15 years, (4) similar trends in smoking for most subgroups since the early 1990s, and (5) a large decline in smoking among young adults with less than a high school education. Long-term patterns for adolescent and young adult cigarette smoking were decidedly nonlinear, and we found evidence of a cohort effect among young adults. Continued strong efforts and a long-term societal commitment to tobacco use prevention are needed, given the unprecedented declines in smoking among most subpopulations since the mid- to late 1990s.

    Despite considerable use of make your own (MYO) cigarettes worldwide and increasing use in the United States, relatively little is known about how these cigarettes are smoked and the resultant toxicant exposure. In a laboratory study, we compared two types of MYO cigarettes-roll your own (RYO) and personal machine made (PMM)-with factory-made (FM) cigarettes in three groups of smokers who exclusively used RYO (n = 34), PMM (n = 23), or FM (n = 20). Within each group, cigarettes were smoked in three conditions: (i) after confirmed overnight tobacco abstinence; (ii) in an intense smoking paradigm; and (iii) without restrictions. All cigarettes were smoked ad lib through a smoking topography unit. Plasma nicotine significantly increased after cigarettes in all conditions except PMM in the intense smoking paradigm. Puff volume, puff duration, total puff volume, and puff velocity did not differ between cigarette types but the puffs per cigarette and time to smoke were significantly smaller for RYO compared with PMM and FM. Regardless of the cigarette, participants consumed the first three puffs more vigorously than the last three puffs. Despite the belief of many of their consumers, smoking MYO cigarettes is not a safe alternative to FM cigarettes. Like FM, MYO cigarettes expose their users to harmful constituents of tobacco smoke. Despite differences in size and design their puffing profiles are remarkably similar. These data are relevant to health and regulatory considerations on the MYO cigarettes. ©2014 American Association for Cancer Research.

    In the United States, many states have established minimum legal purchase ages for electronic nicotine delivery systems (ENDS) to ban adolescent purchases, but these policies may also affect other related substance use. We explore whether ENDS are substitutes or complements for cigarettes, cigars, smokeless tobacco, and marijuana among adolescents by using variation in state-level implementation of ENDS age purchasing restrictions. We linked data on ENDS age purchasing restrictions to state- and year-specific rates of adolescent tobacco and marijuana use in 2007-2013 from the Youth Risk Behavior Surveillance System. This data provides a nationally representative sample of adolescents who attend public and private schools. We performed a fixed effect regression analysis exploring the influence of ENDS age purchasing restrictions on outcomes of tobacco use and marijuana use, controlling for state and year fixed characteristics, age-race cohorts, cigarette excise taxes, and cigarette indoor use restrictions. For cigarette use, we separate our results into cigarette use frequency. We found causal evidence that ENDS age purchasing restrictions increased adolescent regular cigarette use by 0.8 percentage points. ENDS age purchasing restrictions were not associated with cigar use, smokeless tobacco use, or marijuana use. We document a concerning trend of cigarette smoking among adolescents increasing when ENDS become more difficult to purchase. Copyright © 2016 Elsevier Inc. All rights reserved.

    The pharmacokinetics of nicotine and its major metabolites was evaluated in male rats after multiple-cigarette smoke exposure. A smoke-exposure apparatus was used to deliver cigarette smoke to the exposure chamber. The rats were exposed to smoke from a single cigarette every 8 hr for 14 days and to the smoke of a cigarette spiked with radiolabeled nicotine on the 15th day. Blood and urine samples were collected at timed intervals during the 10-min smoke-exposure period of the last cigarette and up to 48 hr thereafter. Nicotine, cotinine, and other polar metabolites were separated by thin-layer chromatography and quantified by liquidmore » scintillation counting. The data were analyzed by computer fitting, and the derived pharmacokinetic parameters were compared to those observed after a single iv injection of nicotine and after a single-cigarette smoke exposure. The results indicated that the amount of nicotine absorbed from multiple-cigarette smoke was approximately 10-fold greater than that absorbed from a single cigarette. Also, unlike the single-cigarette smoke exposure experiment, nicotine plasma levels did not decay monotonically but increased after the 5th hr, and high plasma concentrations persisted for 30 hr. The rate and extent of the formation of cotinine, the major metabolite of nicotine, were decreased as compared with their values following a single-cigarette smoke exposure. It was concluded that nicotine or a constituent of tobacco smoke inhibits the formation of cotinine and may affect the biotransformation of other metabolites. Urinary excretion tended to support the conclusions that the pharmacokinetic parameters of nicotine and its metabolites were altered upon multiple as compared to single dose exposure.« less

    Patients receiving medication assisted therapy (MAT) for opioid use disorder have high cigarette smoking rates. Cigarette smoking interventions have had limited success. We evaluated an intervention to increase cigarette abstinence rates in patients receiving buprenorphine-assisted therapy. Cigarette smokers (N = 175; 78% male; 69% Caucasian; 20% Hispanic), recruited from a buprenorphine clinic were randomly assigned to either an extended innovative system intervention (E-ISI) or to Standard Treatment Control (STC). The E-ISI combined motivational intervention with extended treatment (long-term nicotine replacement therapy , varenicline, and extended cognitive behavioral therapy). STC received written information about quit-lines, medication, and resources. Assessments were held at baseline and 3, 6, 12, and 18 months. Seven-day biochemically verified point-prevalence cigarette abstinence was the primary outcome measure. Fifty-four percent of E-ISI participants entered the extended treatment intervention; E-ISI and STC differed at 3 months on abstinence status but not at months 6, 12, and 18. E-ISI participants were more likely to attempt to quit, to have a goal of complete abstinence, and to be in a more advanced stage of change than STC participants. A higher number of cigarettes smoked and the use of cannabis in the previous 30 days predicted continued smoking. The E-ISI was successful in increasing motivation to quit smoking but did not result in long-term abstinence. The failure of treatments that have been efficacious in the general population to produce abstinence in patients receiving MAT of opioid use disorder suggests that harm reduction and other innovative interventions should be explored. This study demonstrates that an intervention combining motivational interviewing with an extended treatment protocol can increase cigarette quit attempts, enhance cigarette abstinence goals, and further movement through stages of change about quitting smoking in

    Smoking is a leading cause of mortality and morbidity worldwide. Smoking initiation often occurs during adolescence. This paper reviews and synthesizes adolescent development and nicotine dependence literatures to provide an account of adolescent smoking from onset to compulsive use. We extend neurobiological models of adolescent risk-taking, that focus on the interplay between incentive processing and cognitive control brain systems, through incorporating psychosocial and contextual factors specific to smoking, to suggest that adolescents are more vulnerable than adults to cigarette use generally, but that individual differences exist placing some adolescents at increased risk for smoking. Upon smoking, adolescents are more likely to continue smoking due to the increased positive effects induced by nicotine during this period. Continued use during adolescence, may be best understood as reflecting drug-related changes to neural systems underlying incentive processing and cognitive control, resulting in decision-making that is biased towards continued smoking. Persistent changes following nicotine exposure that may underlie continued dependence are described. We highlight ways that interventions may benefit from a consideration of cognitive-neuroscience findings. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Smoking in women is a well-recognized public health problem. In many developed countries, cigarette smoking is now the single most important preventable cause of premature death in women. There are relatively few data on the epidemiology of cigarette smoking in Asian women, and this study examined the prevalence of and factors predisposing Chinese women to smoke cigarettes in Hong Kong. A territory-wide random telephone survey of 26,716 households in Hong Kong was conducted. A total of 1064 current smokers and 291 ex-smokers were identified in these household, and in-depth interviews of 791 current smokers, 221 ex-smokers, and 1012 controls were conducted. The prevalence of cigarette smoking was 4.5% in women who were 25 years or younger, 2.6% in women aged 46-65 years, and 2.2% in women aged 65 years or older. Sixty-four percent of current smokers started when they were 19 years or younger. The main reasons for the initiation of cigarette smoking were the influence of friends, curiosity, feeling bored, or being idle. Current smokers and ex-smokers tended to have positive images of women who smoked. The following risk factors were found to be significant for cigarette smoking: less than university education, unemployment, being divorced, having a husband who smoked, and a low score on the perceived harms of cigarette smoking. Cigarette smoking is more prevalent in younger women in Hong Kong; and psychosocial issues should be addressed to prevent future epidemics.

    A recent WHO data report on mortality attributable to tobacco use including cigarette smoking indicated a very high burden of deaths in Asia and that people often initiate smoking as early as young adolescents. The objectives of this study were to systematically review peerreviewed articles on cigarette smoking initiation among Asian adolescents and to develop a conceptual model of factors influencing smoking initiation by integrating all relevant factors based on existing data. Following a PRISMA guideline, a systematic review of articles published between 2005 and June 2015 was conducted using 5 databases on cigarette smoking initiation among adolescents (aged 1019 years) living in Asia. We summarized the main findings of each study according to our research questions and data that emerged during the data extraction process. Analysis and categorization were based on the TTI and TPB models and classification of factors extracted from the study, were as follows: personal factors, social factors, broader environmental factors, mediators, and intention to initiate smoking and smoking behavior. Of 1,227 identified studies, only 20 were included in this review. Our findings found that the mean age of cigarette smoking initiation ranged from 10 to 14 years and those who are more likely to initiate smoking are male, older adolescents, adolescents with low parental SES, individuals with low parental monitoring, low parental education level and having no discussion on smoking at home, those living in public housing and those exhibiting healthrisk behavior. Our study also revealed that the risk of smoking initiation increased when they are exposed to smokers, influenced by peers, exposed to tobacco advertisements, receive pocket money, have lack of knowledge about smoking, have poor school performance, have a family conflict and have psychological problems. The conceptual model developed demonstrated complex networks of factors influencing initiation. This systematic review

    Cigarette smoke has been shown to be a major risk factor for bladder cancer. Epithelial-mesenchymal transition (EMT) is a crucial process in cancer development. The role of MAPK pathways in regulating cigarette smoke-triggered urocystic EMT remains to be elucidated. Human normal urothelial cells and BALB/c mice were used as in vitro and in vivo cigarette smoke exposure models. Exposure of human normal urothelial cells to cigarette smoke induced morphological change, enhanced migratory and invasive capacities, reduced epithelial marker expression and increased mesenchymal marker expression, along with the activation of MAPK pathways. Moreover, we revealed that ERK1/2 and p38 inhibitors, but rather JNK inhibitor, effectively attenuated cigarette smoke-induced urocystic EMT. Importantly, the regulatory function of ERK1/2 and p38 pathways in cigarette smoke-triggered urocystic EMT was further confirmed in mice exposed to CS for 12 weeks. These findings could provide new insight into the molecular mechanisms of cigarette smoke-associated bladder cancer development as well as its potential intervention.

    The study aim was to examine impulsivity and other risk factors for e-cigarette use among women of reproductive age comparing current daily cigarette smokers to never cigarette smokers. Women of reproductive age are of special interest because of the additional risk that tobacco and nicotine use represents should they become pregnant. Survey data were collected anonymously online using Amazon Mechanical Turk in 2014. Participants were 800 women ages 24-44years from the US. Half (n=400) reported current, daily smoking and half (n=400) reported smoking <100 cigarettes lifetime. Participants completed questionnaires regarding sociodemographics, tobacco/nicotine use, and impulsivity (i.e., delay discounting & Barratt Impulsiveness Scale). Predictors of smoking and e-cigarette use were examined using logistic regression. Daily cigarette smoking was associated with greater impulsivity, lower education, past illegal drug use, and White race/ethnicity. E-cigarette use in the overall sample was associated with being a cigarette smoker and greater education. E-cigarette use among current smokers was associated with increased nicotine dependence and quitting smoking; among never smokers it was associated with greater impulsivity and illegal drug use. E-cigarette use was associated with hookah use, and for never smokers only with use of cigars and other nicotine products. E-cigarette use among women of reproductive age varies by smoking status, with use among current smokers reflecting attempts to quit smoking whereas among non-smokers use may be a marker of a more impulsive repertoire that includes greater use of alternative tobacco products and illegal drugs.

    Drawing on the 1998 China national health services survey data, this study estimated the poverty impact of two smoking-related expenses: excessive medical spending attributable to smoking and direct spending on cigarettes. The excessive medical spending attributable to smoking is estimated using a regression model of medical expenditure with smoking status (current smoker, former smoker, never smoker) as part of the explanatory variables, controlling for people's demographic and socioeconomic characteristics. The poverty impact is measured by the changes in the poverty head count, after smoking-related expenses are subtracted from income. We found that the excessive medical spending attributable to smoking may have caused the poverty rate to increase by 1.5% for the urban population and by 0.7% for the rural population. To a greater magnitude, the poverty headcount in urban and rural areas increased by 6.4% and 1.9%, respectively, due to the direct household spending on cigarettes. Combined, the excessive medical spending attributable to smoking and consumption spending on cigarettes are estimated to be responsible for impoverishing 30.5 million urban residents and 23.7 million rural residents in China. Smoking related expenses pushed a significant proportion of low-income families into poverty in China. Therefore, reducing the smoking rate appears to be not only a public health strategy, but also a poverty reduction strategy.

    The U.S. Surgeon General has concluded that the burden of death and disease from tobacco use in the United States is overwhelmingly caused by cigarettes and other combusted tobacco products (1). Cigarettes are the most commonly used tobacco product among U.S. adults, and about 480,000 U.S. deaths per year are caused by cigarette smoking and secondhand smoke exposure (1). To assess progress toward the Healthy People 2020 target of reducing the proportion of U.S. adults aged ≥18 years who smoke cigarettes to ≤12.0% (objective TU-1.1),* CDC analyzed data from the 2016 National Health Interview Survey (NHIS). In 2016, the prevalence of current cigarette smoking among adults was 15.5%, which was a significant decline from 2005 (20.9%); however, no significant change has occurred since 2015 (15.1%). In 2016, the prevalence of cigarette smoking was higher among adults who were male, aged 25-64 years, American Indian/Alaska Native or multiracial, had a General Education Development (GED) certificate, lived below the federal poverty level, lived in the Midwest or South, were uninsured or insured through Medicaid, had a disability/limitation, were lesbian, gay, or bisexual (LGB), or had serious psychological distress. During 2005-2016, the percentage of ever smokers who quit smoking increased from 50.8% to 59.0%. Proven population-based interventions are critical to reducing the health and economic burden of smoking-related diseases among U.S. adults, particularly among subpopulations with the highest smoking prevalences (1,2).

    Cigarette smoking—a crucial modifiable risk factor for organ system diseases and cancer—remains prevalent in the United States and globally. In this literature review, we aim to summarize the epidemiology of cigarette smoking and tobacco use in the United States, pharmacology of nicotine—the active constituent of tobacco, and health consequence of cigarette smoking. This article also reviews behavioral and pharmacologic interventions for cigarette smokers and provides cost estimates for approved pharmacologic interventions in the United States. A literature search was conducted on Google Scholar, EBSCOhost, ClinicalKey, and PubMed databases using the following headings in combination or separately: cigarette smoking, tobacco smoking, epidemiology in the United States, health consequences of cigarette smoking, pharmacologic therapy for cigarette smoking, and non-pharmacologic therapy for cigarette smoking. This review found that efficacious non-pharmacologic interventions and pharmacologic therapy are available for cessation of cigarette smoking. Given the availability of efficacious interventions for cigarette smoking cessation, concerted efforts should be made by healthcare providers and public health professionals to promote smoking cessation as a valuable approach for reducing non-smokers’ exposure to environmental tobacco smoke.

Three-wave school-based cohort study of rural Vermont adolescents attending 3 K-12 schools. We evaluate cross-sectional and longitudinal associations between perceived parental disapproval of smoking and the adoption of smoking behavior. Students' perceptions of their parents' reaction to their own smoking was ascertained by asking the following question for mothers and fathers: "How do you think your mother (father) would react if you were smoking cigarettes and she (he) knew about it?" A response of "S/he would tell me to stop and be very upset" was considered to indicate strong parental disapproval. Outcome measures include a 6-level smoking index for cross-sectional analyses and, for a longitudinal analysis of 372 never smokers at baseline, being an established smoker (smoked > or =100 cigarettes lifetime and within the past 30 days) by survey 3. The study samples for the cross-sectional analyses were 662 (baseline), 758 (year 2), and 730 (year 3). Students were equally distributed across grade (4th-11th grades) and gender. At baseline, most (65.9%) adolescents perceived both parents as disapproving of smoking, with 110 (16.6) perceiving 1 parent as disapproving, and 116 (17.5%) perceiving neither parent as disapproving. Perceived disapproval of smoking was inversely associated with adolescent smoking, grade in school, parental and sibling smoking, friend smoking, and ownership of tobacco promotional items. After controlling for confounding influences, adolescents who perceived strong parental disapproval of their smoking were less than half as likely to have higher smoking index levels compared with those who did not perceive strong parental disapproval. In the longitudinal sample of baseline never smokers, those who perceived strong disapproval in both parents at baseline were less than half as likely to become established smokers

    Objective To test the hypothesis that greater exposure to smoking in films is associated with trying smoking among adolescents. Design Cross sectional survey of 4919 schoolchildren aged 9-15 years, and assessment of occurrence of smoking in 601 films. Setting Randomly selected middle schools in Vermont and New Hampshire, USA. Main outcome measure Number of schoolchildren who had ever tried smoking a cigarette. Results The films contained a median of 5 (interquartile range 1-12) occurrences of smoking. The typical adolescent had seen 17 of 50 films listed. Exposure to smoking in films varied widely: median 91 (49-152) occurrences. The prevalence of ever trying smoking increased with higher categories of exposure: 4.9% among students who saw 0-50 occurrences of smoking, 13.7% for 51-100 occurrences, 22.1% for 101-150, and 31.3% for >150. The association remained significant after adjustment for age; sex; school performance; school; parents' education; smoking by friend, sibling, or parent; and receptivity to tobacco promotions. The adjusted odds ratios of ever trying smoking for students in the higher categories of exposure, compared with students exposed to 0-50 occurrences of smoking in films, were 1.7 (95% confidence interval 1.2 to 2.4), 2.4 (1.7 to 3.4), and 2.7 (2.0 to 3.8). These odds ratios were not substantially affected by adjustment for parenting style or for personality traits of the adolescent. Conclusion In this sample of adolescents there was a strong, direct, and independent association between seeing tobacco use in films and trying cigarettes, a finding that supports the hypothesis that smoking in films has a role in the initiation of smoking in adolescents. What is already known on this topicSmoking is often depicted in films, and watching films is a favourite activity of adolescentsAdolescents whose favourite actors smoke in films are more likely to have tried smokingWhat this study addsAdolescents' exposure to smoking in films varies widelyAdolescents

  7. Children's hedonic judgments of cigarette smoke odor: effects of parental smoking and maternal mood.

    Age-appropriate tasks were used to assess 3- to 8-year-old children's liking, identification, and preference for a variety of odors, including that of exhaled cigarette smoke. Children whose parents smoke took longer to decide whether they liked the cigarette odor and were significantly more likely to prefer the odor of cigarette to the neutral and unfamiliar odor of green tea compared with children of nonsmokers. Among children of smokers, relative preferences for the cigarette odor were related to maternal mood disturbance and depression scores. These findings suggest that some early learning about cigarette smoke odor is based on sensory experiences at home and anchors it to the emotional context in which their mothers smoke.

    Although epidemiological evidence on the role of active cigarette smoking in breast cancer risk has been inconsistent, recent literature supports a modest association between smoking and breast cancer. This association is particularly observed in women who smoke for a long duration, or who smoke for a long time prior to their first pregnancy. Here, we provide updated results on cigarette smoking and breast cancer risk in the Canadian National Breast Screening Study (NBSS). The NBSS is a large cohort of 89,835 women, aged 40-59, who were followed for a mean of 22.1 years, resulting in the ascertainment of 6,549 incident cases of breast cancer. Cox proportional hazard models were used to estimate hazard ratios (HR) and 95% confidence intervals (CI) for the association of cigarette smoking variables with breast cancer risk. We found breast cancer to be associated with duration (40 years vs. 0: HR = 1.57; 95%CI = 1.29-1.92), intensity (40 cigarettes per day vs. 0: HR = 1.21; 95%CI = 1.04-1.40), cumulative exposure (40 pack-years vs. 0: HR = 1.19; 95%CI = 1.06-1.13) and latency (40 years since initiation vs. 0: HR = 1.19; 95%CI = 1.10-1.53) of cigarette smoking. Number of years smoked prior to first full-term pregnancy was associated with higher risk of breast cancer than comparative years smoked post-pregnancy (among parous women, 5 years pre pregnancy vs. 0: HR = 1.18; 95%CI = 1.10-1.26). These results strongly support a role for cigarette smoking in breast cancer etiology and emphasize the importance of timing of this exposure. © 2014 UICC.

    Smoke-free laws and the addition of graphic warning labels to cigarette packages represent public health policies that can potentially reduce smoking and smoking-related disease. The attitudes and beliefs relating to these policies were examined among residents of Ohio Appalachia, a mostly rural region with high smoking prevalence among its residents. Focus groups were conducted with participants from Ohio Appalachia during the summer of 2007. Groups included healthcare providers (n=37), community leaders (n=31), parents (n=19), and young adult women aged 18-26 years (n=27). Most participants were female (94%), non-Hispanic White (94%), and married (65%). Participants believed that most non-smokers supported Ohio's enforced statewide comprehensive smoke-free law that began in 2007, while some smokers opposed the law due to a perceived infringement of their rights. They also reported that most residents and local businesses were abiding by and enforcing the law. Participants supported the addition of graphic warning labels to cigarette packages in the USA. They believed that such warning labels could help deter adolescents and adult non-smokers from smoking initiation, particularly if the negative aesthetic effects of smoking were emphasized. However, they felt the labels would be less effective among current smokers and older individuals living in their communities. Participants generally held positive views about both the smoke-free law and the addition of graphic warning labels to cigarette packages in the USA. These tobacco-related public health policies are promising strategies for potentially reducing smoking and its associated diseases among residents living in Appalachia. Additional research is needed to further examine support for these policies among more diverse Appalachian populations.

    Objective Our objective was to better understand differences in use behavior and exposure when smoking menthol and nonmenthol cigarettes using a 2-part cross-over design. Methods Adult daily smokers were randomly assigned to alternate between 2 weeks of exclusively smoking a menthol test cigarette or a nonmenthol test cigarette. Urine and saliva were collected for biomarker measurements, carbon monoxide (CO) was measured, and participants smoked test cigarettes through a CreSS® smoking topography device during 3 clinic visits. Participants turned in their cigarette butts from the test periods for determination of mouth level nicotine and completed subjective questionnaires related to the test cigarettes. Results Regardless of cigarette preference, participants had higher salivary cotinine when smoking the nonmenthol test cigarette, but there were no significant differences detected in urine 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol between the 2 test cigarettes. Mouth level nicotine, puff volume and puff duration were significantly higher when smoking the menthol brand. Both menthol and nonmenthol smokers reported significantly lower enjoyment and satisfaction scores for test cigarettes compared with their brand of choice. Conclusions Our results suggest that mentholation has an effect on measures of smoking behavior and that mouth level nicotine is a useful indicator of between-brand smoke exposure. PMID:28376975

  11. Polonium in cigarette smoke and radiation exposure of lungs

    Polonium (210Po), the most volatile of naturally-occurring radionuclides in plants, was analysed in three common brands of cigarettes produced in Portugal. The analyses were carried out on the unburned tobacco contained in cigarettes, on the ashes and butts of smoked cigarettes and on the mainstream smoke. 210Po in tobacco displays concentrations ranging from 3 to 37 mBq g-1, depending upon the cigarette brand. The 210Po activity remaining in the solid residue of a smoked cigarette varied from 0.3 to 4.9 mBq per cigarette, and the 210Po in the inhaled smoke varied from 2.6 to 28.9 mBq. In all brands of cigarettes tested, a large fraction of the 210Po content is not inhaled by the smoker and it is released into the atmosphere. Part of it may be inhaled by passive smokers. Depending upon the commercial brand and upon the presence or absence of a filter in the cigarette, 5 to 37 % of the 210Po in the cigarette can be inhaled by the smoker. Taking into account the average 210Po in surface air, the smoker of one pack of twenty cigarettes per day may inhale 50 times 210Po than a non smoker. Cigarette smoke contributes with 1.5 % to the daily rate of 210Po absorption into the blood, 0.39 Bq d-1, and, after systemic circulation it gives rise to a whole body radiation dose in the same proportion. However, in the smoker the deposition of 210Po in the lungs is much more elevated than normal and may originate an enhanced radiation exposure. Estimated dose to the lungs is presented and radiobiological effects of cigarette smoke are discussed.

    2016-03-01

    To describe experiences with and beliefs about e-cigarettes as safe and useful aids for smoking cessation among healthcare professionals providing smoking cessation services. Using a cross-sectional design, anonymous structured questionnaires were completed by 179 healthcare professionals in public smoking cessation clinics across 20 regions in Italy. Service providers reported that considerably more smokers made inquiries about e-cigarettes in 2014 than in 2013. The most frequent inquiries concerned the ingredients, safety and effectiveness of e-cigarettes as smoking cessation aids. Clients used e-cigarettes to quit smoking, cut down the number of conventional cigarettes smoked, have a safe alternative to smoking, and protect their health while continuing to smoke. More than 60 % of service providers reported favourable beliefs about the safety and effectiveness of e-cigarettes, and believed that e-cigarettes are as effective as other smoking cessation aids, including pharmacotherapy. Despite limited empirical evidence, service providers in Italy viewed e-cigarettes, as safe and effective smoking cessation aids. More concerted efforts are needed to improve knowledge about e-cigarettes among service providers, to guide their clinical practice and decision-making with respect to e-cigarettes.

    Cigarette-smoking is a dominant cause of lung cancer and confounds risk assessment of exposure to radon decay products. Evidence in humans on the interaction between cigarette-smoking and exposure to radon decay products, although limited, indicates a possible synergy. Experimental animal data, in addition to showing synergy, also show a decrease or no change in risk with added cigarette-smoke exposures. This article reviews previous animal data developed at Compagnie Generale des Matieres Nucleaires and Pacific Northwest Laboratory (PNL) on mixed exposures to radon and cigarette smoke, and highlights new initiation-promotion-initiation (IPI) studies at PNL that were designed within the framework ofmore » a two-mutation carcinogenesis model. Also presented are the PNL exposure system, experimental protocols, dosimetry, and biological data observed to date in IPI animals.« less

    2015-11-01

    Hookah use is increasingly common among U.S. college students, but little is known regarding the relationship between hookah and cigarette use. The purpose of this study was to test the hypothesis that the added nicotine exposure from hookah use may accelerate the uptake of cigarettes. An ethnically diverse sample of college students (n = 256; 43% female) who had smoked cigarettes in the past month completed 2 in-person interviews over 6 months. This study was a secondary analysis of data collected for a longitudinal study of young adult cigarette smoking patterns. Analyses examined 6-month changes in past 30 day cigarettes smoked and number of days smoking, controlling for age, nicotine dependence, marijuana use, and the respective baseline variable for each outcome. Current hookah use (any use in past 30 days) was endorsed by 34% of participants at baseline, while 94% reported lifetime use. Change in past 30 day number of cigarettes (p = .043) and number of smoking days (p = .040) differed significantly between those who did or did not report recent hookah use at baseline. Hookah users reported a greater number of cigarettes smoked at the 6-month follow-up, while nonusers decreased their smoking quantity. For number of smoking days in the past 30, hookah users reported a smaller decrease than nonusers. Recent hookah use predicted increased cigarette smoking over 6 months in a college sample. These are the first prospective data demonstrating this relationship, indicating the value of developing strategies to prevent hookah use among college students. © The Author 2015.

  15. Cigarette smoke destabilizes NLRP3 protein by promoting its ubiquitination.

    2017-01-05

    Cigarette smoke suppresses innate immunity, making smokers more susceptible to infection. The NLRP3 inflammasome is a multi-protein complex that releases interleukin (IL) -1β and IL -18. These cytokines are critical for a timely host response to pathogens. Whether cigarette smoke affects NLRP3 protein levels, and its ability to form an inflammasome, is not known. Using the human monocyte THP1 cell line and C57BL/6 mice, we show that cigarette smoke decreases NLRP3 levels in cells by increasing ubiquitin-mediated proteasomal processing. Half-life of NLRP3 is shortened with the exposure to cigarette smoke extract. Cigarette smoke extract reduces cellular NLRP3 protein abundance in the presence of lipopolysaccharide, a known inducer of NLRP3 protein, thereby decreasing the formation of NLRP3 inflammasomes. The release of IL-1β and IL-18 by inflammasome activation is also decreased with the exposure to cigarette smoke extract both in THP1 cells and primary human peripheral blood macrophages. Cigarette smoke extract decreased NLRP3 protein abundance via increased ubiquitin-mediated proteasomal processing. The release of IL-1β and IL-18 is also decreased with cigarette smoke extract. Our findings may provide mechanistic insights on immunosuppression in smokers and unique opportunities to develop a strategy to modulate immune function.

  16. Sources of cigarettes among adolescent smokers: Free or purchased?

    Jansen, Paul; Toomey, Traci L; Nelson, Toben F; Fabian, Lindsey E A; Lenk, Kathleen M; Forster, Jean L

    Few studies have described youth cigarette sources in terms of whether the cigarettes were free or purchased. Understanding the different ways youth obtain tobacco can guide development of interventions to more effectively reduce youth smoking. To determine the propensity for youth to purchase cigarettes versus obtain cigarettes for free, and the factors associated with each obtainment method. Our sample included 812 youth ages 12-17 who reported ever smoking a whole cigarette. Our outcome was the source of the last cigarette smoked (purchased vs. free) and independent variables included demographics, smoking behaviors, and smoking status of parents/siblings/friends. We conducted logistic regression to assess relationships between outcome and independent variables. Eighty-four percent of youth obtained their last cigarette for free and 16% purchased their last cigarette. Youth who smoked less and had less weekly spending money were more likely to have obtained their last cigarette for free. Youth smokers appear to have a high propensity to obtain their cigarette for free, particularly those who smoke relatively infrequently. Interventions that target sources of free cigarettes have the potential to reduce the progression of youth smoking at a critical stage in its development.

    The authors investigated the association between exposure to smoking in movies and the initiation and progression of adolescent smoking over time among 6,522 U.S. adolescents (between the ages of 10 and 14 years, at baseline) in a nationally representative, 4-wave random-digit-dial telephone survey. They conducted a hazard (survival) analysis testing whether exposure to movie smoking and demographic, personality, social, and structural factors predict (a) earlier smoking onset and (b) faster transition to experimental (1-99 cigarettes/lifetime) and established smoking (>100 cigarettes/lifetime). Results suggest that higher exposure to movie smoking is associated with less time to trying cigarettes for the first time (adjusted hazard ratio = 1.66; 95% CI [1.37, 2.01]) but not with faster escalation of smoking behavior following initiation (adjusted hazard ratio = 1.53; 95% CI [0.84, 2.79]). In contrast, age, peer smoking, parenting style, and availability of cigarettes in the home were predictors of earlier onset and faster transition to established smoking. Thus, the authors concluded that the effect of exposure to mass-mediated images of smoking in movies may decline once adolescents have started to smoke, whereas peers and access to tobacco remain influential.

    Cigarette smoking remains a substantial threat to the current and future health of America's youth. The purpose of this study was to identify the risk and protective factors for cigarette smoking among US adolescents. Data from the National Longitudinal Study of Adolescent Health was used, comparing the responses of all non-smokers at Time 1 for their ability to predict the likelihood of smoking at Time 2, one year later. Data was stratified into four gender by grade group cohorts. Cross-cutting risk factors for smoking among all four cohorts were: using alcohol, marijuana, and other illicit drugs; violence involvement; having had sex; having friends who smoke and learning problems. Having a higher grade point average and family connectedness were protective across all cohorts. Other gender and grade group specific risk and protective factors were identified. The estimated probability of initiating smoking decreased by 19.2% to 54.1% both in situations of high and low risk as the number of protective factors present increased. Of the factors that predict or protect against smoking some are influential across all gender and grade group cohorts studied, while others are specific to gender and developmental stage. Prevention efforts that target both the reduction of risk factors and enhancement of protective factors at the individual, family, peer group and community are likely to reduce the likelihood of smoking initiation.

    Individuals seeking information about electronic cigarettes are increasingly turning to social media networks like Twitter. We surveyed dominant Twitter communications about e-cigarettes and smoking cessation, examining message sources, themes, and attitudes. Tweets from 2014 were searched for mentions of e-cigarettes and smoking cessation. A purposive sample was subjected to mixed-methods analysis. Twitter communication about e-cigarettes increased fivefold since 2012. In a sample of 300 tweets from high-authority users, attitudes about e-cigarettes as smoking cessation aids were favorable across user types (industry, press, public figures, fake accounts, and personal users), except for public health professionals, who lacked consensus and contributed negligibly to the conversation. The most prevalent message themes were marketing, news, and first-person experiences with e-cigarettes as smoking cessation aids. We identified several industry strategies to reach Twitter users. Our findings show that Twitter users are overwhelmingly exposed to messages that favor e-cigarettes as smoking cessation aids, even when disregarding commercial activity. This underlines the need for effective public health engagement with social media to provide reliable information about e-cigarettes and smoking cessation online.

    The World Health Organisation called for research assessing the safety of electronic cigarette (e-cigarette). We evaluated the acute effect of active and passive e-cigarette and tobacco cigarette smoking on complete blood count (CBC) markers in 15 smokers and 15 never-smokers, respectively. Smokers underwent a control session, an active tobacco cigarette smoking session, and an active e-cigarette smoking session. Never-smokers underwent a control session, a passive tobacco cigarette smoking session, and a passive e-cigarette smoking session. The results demonstrated that CBC indices remained unchanged during the control session and the active and passive e-cigarette smoking sessions (P>0.05). Active and passive tobacco cigarette smoking increased white blood cell, lymphocyte, and granulocyte counts for at least one hour in smokers and never smokers (P<0.05). It is concluded that acute active and passive smoking using the e-cigarettes tested in the current study does not influence CBC indices in smokers and never smokers, respectively. In contrast, acute active and passive tobacco cigarette smoking increase the secondary proteins of acute inflammatory load for at least one hour. More research is needed to evaluate chemical safety issues and other areas of consumer product safety of e-cigarettes, because the nicotine content in the liquids used may vary considerably.

    Little is known about how adolescents who smoke both cigarettes and cigar products obtain and use these products. This study sought to explore cigarette and cigar acquisition and situational use among high school smokers. Data are drawn from the 2011 Cuyahoga County Youth Risk Behavior Survey. Analysis was limited to youth who smoke cigarettes as well as cigars, cigarillos, and little cigars (CCLC) in the past month (N = 649). Consumption of both products was calculated and used to create four subtypes of users based on high or low use of each product (Dual High, Dual Low, High CCLC/Low Cigarette, and Low CCLC/High Cigarette users). Current users were asked to identify situations in which they use cigarettes and CCLCs and ways in which they obtain these products. Data were analyzed overall and by user subtype. Youth reported acquiring cigarettes and CCLC in similar ways, although youth were more likely to take cigarettes from family members than CCLC (11.1% vs. 4.8%). Several differences were observed between cigarettes and CCLC for situational use. While both products are frequently used in social situations (e.g., with friends), cigarettes were more likely to be used in solitary situations (e.g., before bed). Further, significant differences were observed among the four user subtypes. Study results highlight important, nuanced differences regarding how young multi-tobacco users obtain and the situational use of such products. Importantly, these findings vary by user subtype, informing future interventions to prevent and reduce smoking among the most vulnerable subgroups of youth. Copyright © 2018 Elsevier B.V.

    Objective The association between cigarette smoke exposure and the acute respiratory distress syndrome (ARDS) in patients with the most common ARDS risk factors of sepsis, pneumonia, and aspiration has not been well-studied. The goal of this study was to test the association between biomarker-confirmed cigarette smoking and ARDS in a diverse cohort. Design, Setting, Patients We obtained smoking histories and measured urine NNAL (a biomarker of cigarette smoke exposure) in 426 patients with ARDS risk factors (excluding trauma and transfusion) in a prospective cohort of critically ill patients at a single tertiary care center and tested the association between smoking and ARDS. Interventions None. Measurements and Main Results The association between cigarette smoke exposure and ARDS differed based on ARDS risk factor (p<0.02 for interaction). In patients with non-pulmonary sepsis as the primary ARDS risk factor (n=212), 39% of those with ARDS were current smokers by history, compared with 22% of those without ARDS (odds ratio 2.28 (95% CI 1.24–4.18); p=0.007). Likewise, cigarette smoke exposure as measured by urine NNAL was significantly associated with ARDS in this group. The increased risk of ARDS in non-pulmonary sepsis was restricted to patients with NNAL levels consistent with active smoking and was robust to adjustment for other ARDS predictors. Cigarette smoke exposure as measured by history or NNAL was not associated with ARDS in patients with other risk factors (e.g. pneumonia, aspiration). Conclusions Cigarette smoking measured both by history and by biomarker is associated with an increased risk of ARDS in patients with non-pulmonary sepsis. This finding has important implications for tobacco product regulation and for understanding the pathogenesis of ARDS. PMID:26010690

    Cellular transformation owing to cigarette smoking is due to chronic exposure and not acute. However, systematic studies to understand the molecular alterations in lung cells due to cigarette smoke are lacking. To understand these molecular alterations induced by chronic cigarette smoke exposure, we carried out tandem mass tag (TMT) based temporal proteomic profiling of lung cells exposed to cigarette smoke for upto 12months. We identified 2620 proteins in total, of which 671 proteins were differentially expressed (1.5-fold) after 12months of exposure. Prolonged exposure of lung cells to smoke for 12months revealed dysregulation of oxidative phosphorylation and overexpression of enzymes involved in TCA cycle. In addition, we also observed overexpression of enzymes involved in glutamine metabolism, fatty acid degradation and lactate synthesis. This could possibly explain the availability of alternative source of carbon to TCA cycle apart from glycolytic pyruvate. Our data indicates that chronic exposure to cigarette smoke induces mitochondrial metabolic reprogramming in cells to support growth and survival.

    To identify the prevalence of smoking and the presence of variables associated with the habit in children and adolescents of both sexes, aged 7 to 17 years, resident in the city of Maceió. A cross-sectional epidemiological study of the student population of the both private and public education systems at elementary and high school level. Sample size was calculated based on the minimum predicted prevalence of a large number of variables, including smoking itself. Cluster sampling was employed. A questionnaire on smoking habits was completed during individual interviews with each student. Children who admitted having smoked on 1 or more day during the previous 30 were defined as current smokers. The variables analyzed were related to: the students (age, sex, previous experimentation with cigarettes and paid employment), their educational status (public/private school, daytime/evening lessons, grade and repeated years) and their families (economic status, smoking parents and separated parents). A total of 1,253 students were analyzed (547 were male, mean age was 12.4+/-2.9 years). Observed smoking prevalence was 2.4%. Multivariate statistical analysis demonstrated significant associations between smoking and: increased age (odds ratio: 1.31); previous experimentation with cigarettes (odds ratio: 33.96); studying during the evening (odds ratio: 5.43). It was observed that 286 students (22.8%) admitted having experimented with cigarettes (9% from 7 to 9 years; 21% from 10 to 14 years; 36% from 15 to 17 years). The prevalence of smoking among children and adolescents in the Maceió educational system is 2.4%, being most common among students aged 15 to 17 years, studying in the evening. Students who had experimented with cigarettes exhibited a 34 times greater chance of becoming smokers.

    A large number of colonies of Streptococcus mutans (SM) and Lactobacillus (LB) cariogenic bacteria in the saliva show a high risk of dental caries development. Cotinine is a biomarker of exposure to the tobacco smoke. The aim of the study was assessment of the number of Streptococcus mutans and Lactobacillus in the saliva of non-smokers and smokers considering the duration of smoking and the number of cigarettes smoked daily. The number of SM and LB was analysed in relation to the frequency of oral health check-ups. The investigated group comprised 124 people aged 20-54. 58 (46.8%) reported cigarette smoking; 66 (53.2%) reported they had never smoked cigarettes and had never attempted to smoke. Cotinine concentration in the saliva was assayed using the Cotinine test (Calbiotech), and the number of SM and LB with the use of the CRT bacteria test (Ivoclar Vivadent, Liechtenstein). Statistical analysis was conducted using Chi2 and Mann-Whitney tests. Test values of p<0.05 were considered statistically significant. No essential correlation was stated between the number of SM and LB and the status of smoking, the number of cigarettes smoked daily and duration of cigarette smoking. Smokers who reported having dental check-ups at least once a year significantly more frequently had a small number of LB stated in relation to people who had dental check-ups to control their oral health less frequently than once a year. The number of SM and LB in saliva does not depend on the smoking status, the number of cigarettes smoked daily and duration of smoking.

    Cigarette smoking is the leading preventable cause of death and disease in Canada, and is disproportionately more frequent among psychiatric patients. Smoking cessation interventions can be successfully implemented with psychiatric patients, yet no Canadian studies have evaluated smoking prevalence, nicotine dependence, and motivation for smoking cessation in psychiatric inpatients. Our study did so to help plan appropriate interventions for these patients. All inpatients aged 18 years or older admitted to acute-care psychiatry units at the Foothills Medical Centre in Calgary, Alberta, during a 6-month period completed a survey involving questions from the Canadian Tobacco Use Monitoring Survey, the Fagerstrom Test for Nicotine Dependence (FTND), the Readiness to Quit Ladder, and the Decisional Balance for Cigarette Smoking. Responses were analyzed for correlation with discharge diagnoses, age, and sex. Among the total inpatients (n = 342), 211 (62%) completed the survey. Among those, 55% were current cigarette smokers and 17.5% were former smokers. Nicotine dependence (FTND > or = 6) was reported in 45.2% of smokers. Smoking prevalence and nicotine dependence severity was greatest in the substance use disorders (SUD) and psychotic disorders groups. Current smokers endorsed more negative than positive attributes of smoking. Regarding smoking cessation, 51% of patients were precontemplative, 12.7% contemplative, and 36.2% preparatory or action-oriented, despite few receiving advice to quit. Cigarette smoking and nicotine dependence are highly prevalent in psychiatric inpatients. However, self-reported motivation for smoking cessation is noteworthy, emphasizing that cessation advice and appropriate follow-up care should be provided to psychiatric inpatients who smoke.

    The influence of e-cigarette use on smoking initiation is a highly controversial issue, with limited longitudinal data available for examining temporal associations. We examined e-cigarette use and its association with cigarette-smoking initiation at 1-year follow-up within a large cohort of Canadian secondary school students. We analyzed data from students in grades 9-12 who participated in 2 waves of COMPASS, a cohort study of purposefully sampled secondary schools in Ontario and Alberta, Canada, at baseline (2013/14) and 1-year follow-up (2014/15). We assessed cigarette smoking and e-cigarette use at baseline and follow-up using self-completed surveys. We used generalized linear mixed-effects models to examine correlates of past 30-day e-cigarette use at baseline and smoking initiation between waves within the longitudinal sample. Past 30-day e-cigarette use increased from 2013/14 to 2014/15 (7.2% v. 9.7%, p < 0.001), whereas past 30-day cigarette smoking decreased slightly (11.4% v. 10.8%, p = 0.02). Among the 44 163 students evaluated at baseline, past 30-day e-cigarette use was strongly associated with smoking status and smoking susceptibility. In the longitudinal sample ( n = 19 130), past 30-day use of e-cigarettes at baseline was associated with initiation of smoking a whole cigarette (adjusted odds ratio [OR] 2.12, 95% confidence interval [CI] 1.68-2.66) and with initiation of daily smoking (adjusted OR 1.79, 95% CI 1.41-2.28) at follow-up. E-cigarette use was strongly associated with cigarette smoking behaviour, including smoking initiation at follow-up. The causal nature of this association remains unclear, because common factors underlying the use of both e-cigarettes and conventional cigarettes may also account for the temporal order of initiation. © 2017 Joule Inc. or its licensors.

  11. Ethnic Pride, Traditional Family Values, and Acculturation in Early Cigarette and Alcohol Use Among Latino Adolescents

    A structural equations model examined the influence of three cultural variables of ethnic pride, traditional family values and acculturation, along with the mediating variables of avoidance self-efficacy and perceptions of the “benefits” of cigarette smoking, on cigarette and alcohol use in a sample of Latino middle school students in the Southwest. Girls (N = 585) and boys (N = 360) were analyzed separately. In both groups, higher ethnic pride and traditional family values exerted indirect effects on less cigarette smoking and alcohol use when mediated through greater self-efficacy and less endorsement of the “benefits” of cigarette smoking. Among the girls, greater ethnic pride also had a direct effect on less cigarette and alcohol use. Also, greater acculturation directly predicted more cigarette and alcohol use among the girls, but not among the boys. However, differences between the boys and girls were generally nonsignificant as revealed by multiple group latent variable models. These results offer implications for incorporating cultural variables into the design of culturally relevant prevention interventions that discourage cigarette and alcohol use among Latino adolescents.

  12. The role of ethnicity and neighborhood poverty on the relationship between parenting and adolescent cigarette use.

    Although etiological models of substance use may be different across ethnic groups, how ethnicity might moderate the influence of causal factors is not frequently tested. The influence of parenting on adolescent cigarette smoking may vary across Black and White adolescents. Recent research suggests that parenting may be more strongly predictive of substance use among Blacks. Black parents not only may feel more efficacious in their parenting, compared with their White counterparts, but also may be more likely to set strict rules against smoking. As a result, Black parents may be more effective in preventing their children from engaging in smoking behavior. Also, research suggests that these ethnic differences may vary across community contexts. The present study examined cross-sectionally and longitudinally how ethnicity moderates the relationship between parenting and adolescent cigarette use, and how this moderating effect varies across levels of community risk. A three-way ethnicity x parenting x community risk interaction was tested in a sample of adolescents selected from the National Longitudinal Study of Adolescent Health (Add Health). In general, positive parenting behaviors (e.g., high parental control, high-quality relationship) were related to lower levels of smoking for both Black and White youth; however, when differences were found, this relationship was stronger for Whites. Also, the influence of neighborhood poverty was limited to smoking for White adolescents such that higher levels of neighborhood poverty were associated with increased smoking for White but not Black adolescents. These differences may be related to several factors, including how children are socialized in Black and White families, ethnic differences in reasons for using substances or abstaining, and differences in susceptibility to social influences.

    To determine whether negative mood states constitute a risk factor for daily smoking during adolescence, and to specify the role of familial factors in the association between the two variables. Cross-sectional study of a representative sample (second wave, Panel of Families and Childhood) of Catalan adolescents between 14 and 18 years of age. Six logistic regression models were used for girls (n = 1,442) and six for boys (n =1,100) in order to determine whether negative mood states constitute a risk factor for daily cigarette consumption, and to what extent this effect is attributable to familial factors. The prevalence of daily smoking at ages 17-18 is 3.8% for girls and 3.6 for boys. Feelings of sadness constitute a risk factor for daily cigarette consumption (odds ratio [OR] = 1.633), and communication with the father cancels out this effect. Parental pressure is a risk factor for daily smoking in both sexes (girls, OR = 2.064; boys, OR = 1.784). When parental communication is controlled for, this effect is reduced but not canceled out. Living in a reconstituted family is a risk factor for daily cigarette consumption among boys (OR = 2.988). Intergenerational communication decreases the risk of daily tobacco use among adolescents independently of their mood state. Anti-smoking interventions designed in accordance with these findings may be more effective. Copyright © 2011 SESPAS. Published by Elsevier Espana. All rights reserved.

    Indonesian clove cigarettes (kreteks), typically have the appearance of a conventional domestic cigarette. The unique aspects of kreteks are that in addition to tobacco they contain dried clove buds (15-40%, by wt.), and are flavored with a proprietary "sauce". Whereas the clove buds contribute to generating high levels of eugenol in the smoke, the "sauce" may also contribute other potentially harmful constituents in addition to those associated with tobacco use. We measured levels of eugenol, trans-anethole (anethole), and coumarin in smoke from 33 brands of clove-flavored cigarettes (filtered and unfiltered) from five kretek manufacturers. In order to provide information for evaluating the delivery of these compounds under standard smoking conditions, a quantification method was developed for their measurement in mainstream cigarette smoke. The method allowed collection of mainstream cigarette smoke particulate matter on a Cambridge filter pad, extraction with methanol, sampling by automated headspace solid-phase microextraction, and subsequent analysis using gas chromatography/mass spectrometry. The presence of these compounds was confirmed in the smoke of kreteks using mass spectral library matching, high-resolution mass spectrometry (+/-0.0002 amu), and agreement with a relative retention time index, and native standards. We found that when kreteks were smoked according to standardized machine smoke parameters as specified by the International Standards Organization, all 33 clove brands contained levels of eugenol ranging from 2,490 to 37,900 microg/cigarette (microg/cig). Anethole was detected in smoke from 13 brands at levels of 22.8-1,030 microg/cig, and coumarin was detected in 19 brands at levels ranging from 9.2 to 215 microg/cig. These detected levels are significantly higher than the levels found in commercial cigarette brands available in the United States.

    The electronic nicotine delivery system, also known as the electronic cigarette, is generating considerable controversy, not only in the general population but also among health professionals. Smokers the world over have been increasingly using electronic cigarettes as an aid to smoking cessation and as a substitute for conventional cigarettes. There are few available data regarding the safety of electronic cigarettes. There is as yet no evidence that electronic cigarettes are effective in treating nicotine addiction. Some smokers have reported using electronic cigarettes for over a year, often combined with conventional cigarettes, thus prolonging nicotine addiction. In addition, the increasing use of electronic cigarettes by adolescents is a cause for concern. The objective of this study was to describe electronic cigarettes and their components, as well as to review the literature regarding their safety; their impact on smoking initiation and smoking cessation; and regulatory issues related to their use.

    The high rates of cigarette smoking among depressed persons may be partially explained by increased positive expectancies for cigarette smoking among this population. In view of theoretical and empirical work on depressed people's negative views of the future, though, it would be expected that depressed smokers would hold particularly negative expectancies about the effects of cigarette smoking. The two current studies examined the relations between depression and smoking outcome expectancies in (a) a general population of adult regular smokers and (b) adult smokers seeking to quit smoking. Depressive symptoms and depression proneness both showed significant positive correlations with positive expectancies for cigarette smoking. Several positive correlations with negative expectancies also emerged. Thus, experiencing depressive symptoms may serve to amplify both favorable and unfavorable expectancies about the effects of smoking.

    Electronic cigarettes (e-cigarettes) are subject to considerable public health debate. Most public health experts agree that for smokers who find it particularly challenging to quit, e-cigarettes may reduce harm. E-cigarette use in the home may also reduce children's secondhand smoke (SHS) exposure, although e-cigarette vapour may pose risks. This is the first qualitative study to explore disadvantaged parents' views and experiences of e-cigarettes in relation to reducing SHS exposure in the home. Interviews with 25 disadvantaged parents from Edinburgh who smoked and had children aged 1-3 were conducted in 2013, with 17 re-interviewed in 2014. Accounts of e-cigarette perceptions and use were analysed thematically. E-cigarettes were seen by some as potentially valuable in helping quitting or reducing smoking in difficult circumstances, and protecting children from SHS when smoking outside is constrained. However, parents raised concerns about safety issues and continuing their nicotine addiction. In relation to children, concerns included possible health effects of the vapour, children playing with them and role-modelling e-cigarette use. While significant concerns remain about e-cigarettes, for some parents who find it challenging to quit or safely leave their children to smoke outside, e-cigarettes may offer potential for reducing the harm to them and their children. © The Author 2017.

    There is growing evidence that an adolescent’s decision to try cigarettes is influenced by level of exposure to movies in which smoking is portrayed. Less is known about how ethnicity affects this process. We examined whether acculturation and/or country of birth influence the relationship between exposure to smoking imagery in the movies and experimenting with cigarettes among Mexican origin youth. We prospectively followed 1,328 Mexican origin adolescents aged 11–13 at baseline. We assessed which of 50 movies (randomly selected from a pool of 250 popular contemporary movies released from 1999–2004 and content analyzed for smoking) adolescents had seen. Smoking behavior was assessed at baseline and at 6-month intervals over 24 months. 10% of the adolescents had experimented at baseline; 17% tried subsequently. Multivariate analyses revealed, as exposure to smoking imagery in the movies increased, the chances of having ever experimented (AOR=1.27; 95% CI: 1.10–1.48) and of being a new experimenter (AOR=1.19; 95% CI: 1.01–1.40) increased, equivalent to a 4.2% increased risk of ever and a 3.0% increased risk of new experimenting for each additional quartile of movie exposure. This effect was moderated by country of birth. For Mexican-born youth, exposure to smoking imagery in the movies was the strongest independent predictor of new experimentation (AOR=1.52; 95% CI: 1.14–2.05). For US-born youth, we observed a ceiling effect: the percent of experimenters increased with increasing exposure, and then flattened. Among Mexican-born youth exposure to smoking imagery in the movies may be an important part of the acculturation process associated with smoking initiation. PMID:19959693

  1. Influence of cigarette circumference on smoke chemistry, biological activity, and smoking behaviour.

    Cigarettes with reduced circumference are increasingly popular in some countries, hence it is important to understand the effects of circumference reduction on their burning behaviour, smoke chemistry and bioactivity. Reducing circumference reduces tobacco mass burn rate, puff count and static burn time, and increases draw resistance and rod length burned during puff and smoulder periods. Smoulder temperature increases with decreasing circumference, but with no discernible effect on cigarette ignition propensity during a standard test. At constant packing density, mainstream (MS) and sidestream (SS) tar and nicotine yields decrease approximately linearly with decreasing circumference, as do the majority of smoke toxicants. However, volatile aldehydes, particularly formaldehyde, show a distinctly non-linear relationship with circumference and increases in the ratios of aldehydes to tar and nicotine have been observed as the circumference decreases. Mutagenic, cytotoxic and tumorigenic specific activities of smoke condensates (i.e. per unit weight of condensate) decrease as circumference decreases. Recent studies suggest that there is no statistical difference in mouth-level exposure to tar and nicotine among smokers of cigarettes with different circumferences. Commercially available slim cigarettes usually have changes in other cigarette design features compared with cigarettes with standard circumference, so it is difficult to isolate the effect of circumference on the properties of commercial products. However, available data shows that changes in cigarette circumference offer no discernible change to the harm associated with smoking. Crown Copyright © 2016. Published by Elsevier Inc.

    This study investigated whether Pavlovian extinction occurs during smoking cessation by determining whether experience abstaining from smoking in the presence of cigarette cues leads to decreased probability of lapsing and whether this effect is mediated by craving. Secondary analyses were carried out with data sets from two studies with correlational/observational designs. Data were collected in smokers' natural environments using ecological momentary assessment techniques. Sixty-one and 207 smokers who were attempting cessation participated. Multi-level path models were used to examine effects of prior experience abstaining in the presence of available cigarettes and while others were smoking on subsequent craving intensity and the probability of lapsing. Control variables included current cigarette availability, current exposure to others smoking, number of prior lapses and time in the study. Both currently available cigarettes [odds ratios (OR) = 36.60, 11.59] and the current presence of other smoking (OR = 5.00, 1.52) were powerful predictors of smoking lapse. Repeated exposure to available cigarettes without smoking was associated with a significantly lower probability of lapse in subsequent episodes (OR = 0.44, 0.52). However, exposure to others smoking was not a reliable predictor, being significant only in the smaller study (OR = 0.30). Craving functioned as a mediator between extinction of available cigarettes and lapsing only in the smaller study and was not a mediator for extinction of others smoking in either study. This study showed that exposure to available cigarettes is a large risk factor for lapsing, but that this risk can also be reduced over time by repeated exposures without smoking. Smoking cessation interventions should attempt to reduce cigarette exposure (by training cigarette avoidance) but recognize the potential advantage of unreinforced exposure to available cigarettes. © 2010 The Authors, Addiction © 2010 Society for the Study of

    To test the hypothesis that greater exposure to smoking in films is associated with trying smoking among adolescents. Cross sectional survey of 4919 schoolchildren aged 9-15 years, and assessment of occurrence of smoking in 601 films. Randomly selected middle schools in Vermont and New Hampshire, USA. Number of schoolchildren who had ever tried smoking a cigarette. The films contained a median of 5 (interquartile range 1-12) occurrences of smoking. The typical adolescent had seen 17 of 50 films listed. Exposure to smoking in films varied widely: median 91 (49-152) occurrences. The prevalence of ever trying smoking increased with higher categories of exposure: 4.9% among students who saw 0-50 occurrences of smoking, 13.7% for 51-100 occurrences, 22.1% for 101-150, and 31.3% for >150. The association remained significant after adjustment for age; sex; school performance; school; parents' education; smoking by friend, sibling, or parent; and receptivity to tobacco promotions. The adjusted odds ratios of ever trying smoking for students in the higher categories of exposure, compared with students exposed to 0-50 occurrences of smoking in films, were 1.7 (95% confidence interval 1.2 to 2.4), 2.4 (1.7 to 3.4), and 2.7 (2.0 to 3.8). These odds ratios were not substantially affected by adjustment for parenting style or for personality traits of the adolescent. In this sample of adolescents there was a strong, direct, and independent association between seeing tobacco use in films and trying cigarettes, a finding that supports the hypothesis that smoking in films has a role in the initiation of smoking in adolescents.

    Cue-reactivity theory suggests smoking-related visual cues such as point-of-sale (POS) marketing (e.g., advertising, product displays) may undermine cessation attempts by causing an increase in nicotine cravings among users. This study examined the relationship between recall of exposure to POS marketing and subsequent cessation behaviors among young adult cigarette smokers. Participants included 813 18-29 year old (m=21.1, sd=2.70) current cigarette smokers attending 24 Texas colleges. Multivariable logistic regression models examined the impact of baseline self-reported exposure to cigarette and e-cigarette advertising and product displays, on using e-cigarettes for cessation and successful cigarette cessation at 6-month follow-up. Two-way interactions between product-specific advertising and between product-specific displays were examined to determine if the marketing of one product strengthened the cue-reactivity of the other. Baseline covariates included socio-demographic factors, past quit attempts, intentions to quit smoking, and nicotine dependence. Exposure to e-cigarette displays was associated with lower odds of cigarette smoking cessation, controlling for covariates and conventional cigarette display exposure. E-cigarette advertising was positively associated with use of e-cigarettes for cigarette cessation among participants exposed to low (i.e., at least one standard deviation below the mean) levels of cigarette advertising. Cigarette advertising was associated with use of e-cigarettes for cigarette cessation only among those exposed to low levels of e-cigarette advertising. Exposure to cigarette displays was not associated with either outcome. Smoking-related cues at POS may undermine successful cigarette cessation. Exposure to product displays decrease odds of cessation. Advertising exposure increased odds for using e-cigarettes for cessation attempts, but may have guided smokers towards an unproven cessation aid. By examining the interaction of

    Background: In 2011, the courts ruled in favor of tobacco companies in preventing the implementation of graphic warning labels (GWLs) in the US, stating that FDA had not established the effectiveness of GWLs in reducing smoking. Methods: Data came from various sources: the WHO MPOWER package (GWLs, MPOWER policy measures, cigarette prices), Euromonitor International (smoking prevalence, cigarette consumption), and the World Bank database (countries’ demographic characteristics). The datasets were aggregated and linked using country and year identifiers. Fractional logit regressions and OLS regressions were applied to examine the associations between GWLs and smoking prevalence and cigarette consumption, controlling for MPOWER policy scores, cigarette prices, GDP per capita, unemployment, population aged 15–64 (%), aged 65 and over (%), year indicators, and country fixed effects. Results: GWLs were associated with a 0.9–3 percentage point decrease in adult smoking prevalence and were significantly associated with a reduction of 230–287 sticks in per capita cigarette consumption, compared to countries without GWLs. However, the association between GWLs and cigarette consumption became statistically insignificant once country indicators were included in the models. Conclusions: The implementation of GWLs may be associated with reduced cigarette smoking. PMID:29495581

    There is interest in the relative toxicities of emissions from electronic cigarettes and tobacco cigarettes. Lists of cigarette smoke priority toxicants have been developed to focus regulatory initiatives. However, a comprehensive assessment of e-cigarette chemical emissions including all tobacco smoke Harmful and Potentially Harmful Constituents, and additional toxic species reportedly present in e-cigarette emissions, is lacking. We examined 150 chemical emissions from an e-cigarette (Vype ePen), a reference tobacco cigarette (Ky3R4F), and laboratory air/method blanks. All measurements were conducted by a contract research laboratory using ISO 17025 accredited methods. The data show that it is essential to conduct laboratory air/method measurements when measuring e-cigarette emissions, owing to the combination of low emissions and the associated impact of laboratory background that can lead to false-positive results and overestimates. Of the 150 measurands examined in the e-cigarette aerosol, 104 were not detected and 21 were present due to laboratory background. Of the 25 detected aerosol constituents, 9 were present at levels too low to be quantified and 16 were generated in whole or in part by the e-cigarette. These comprised major e-liquid constituents (nicotine, propylene glycol, and glycerol), recognized impurities in Pharmacopoeia-quality nicotine, and eight thermal decomposition products of propylene glycol or glycerol. By contrast, approximately 100 measurands were detected in mainstream cigarette smoke. Depending on the regulatory list considered and the puffing regime used, the emissions of toxicants identified for regulation were from 82 to >99% lower on a per-puff basis from the e-cigarette compared with those from Ky3R4F. Thus, the aerosol from the e-cigarette is compositionally less complex than cigarette smoke and contains significantly lower levels of toxicants. These data demonstrate that e-cigarettes can be developed that offer the potential

    Scenes in movies where smoking occurs have been empirically shown to influence teenagers to smoke cigarettes. The capacity of a Canadian warning label on cigarette packages to decrease the effects of smoking scenes in popular movies has been investigated. A 2 x 3 factorial design was used to test the effects of the same movie scene with or without electronic manipulation of all elements related to smoking, and cigarette pack warnings, i.e., no warning, text-only warning, and text+picture warning. Smoking-related stereotypes and intent to smoke of teenagers were measured. It was found that, in the absence of warning, and in the presence of smoking scenes, teenagers showed positive smoking-related stereotypes. However, these effects were not observed if the teenagers were first exposed to a picture and text warning. Also, smoking-related stereotypes mediated the relationship of the combined presentation of a text and picture warning and a smoking scene on teenagers' intent to smoke. Effectiveness of Canadian warning labels to prevent or to decrease cigarette smoking among teenagers is discussed, and areas of research are proposed.

    One of the main strategies to prevent smoking is delaying onset of smoking in adolescents. Thus, identifying the age of smoking and smoking pattern in adolescents gives important knowledge for planning the intervention programs on smoking. Students aged 13-15 years old living in the Northern and the Southern Tehran were selected through two separate snowball samplings. In each area six smokers were considered as the seeds and were asked to introduce a smoker friend. The sampling continued until one hundred study subjects were recruited in each area. Although in the area with wealthier socioeconomic status the age at which smoking started was one year more, the number of days of smoking, number of consumed cigarettes, not willingness to quit smoking, ease of access to cigarettes, mother and siblings smoking were more frequent. In contrast, seeing anti-smoking advertisements, father smoking, teachers smoking and education about the adverse effects of smoking were lower than the area with poorer socioeconomic status. The community level interventions such as not selling cigarettes to juniors, quit smoking help and support, and education of families must be revised. The role of families, through the supervision and control over their children, and parents' avoidance of smoking should be emphasized.

    To estimate the proportion of smokers that could potentially have been prevented from smoking by limiting the amount of pocket money received by Chinese adolescents. Cross-sectional study. Current smoking, ever smoking and the amount of pocket money were determined through self-administered questionnaires among 12,708 adolescents (aged 12-18 years) from 21 schools in Shanghai, China. Adjusted odds ratios for current smoking ranged from 2.0 [95% confidence interval (CI) 1.5-2.7] for adolescents receiving 200-399 Reminbin (RMB)/month as pocket money to 6.5 (95% CI 3.3-12.7) for those receiving ≥1000 RMB/month, compared with those receiving <200 RMB/month. The crude population-attributable risk percentage (PAR%) due to higher pocket money (≥200 RMB/month) for current smoking was 50.4% (95% CI 42.2-57.4), and adjusted PAR% was 43.3% (95% CI 30.7-53.1). Approximately half of current smokers may have been prevented from smoking if pocket money was limited to <200 RMB/month among Chinese adolescents. An even larger proportion could have been prevented from smoking if pocket money was reduced further. It is recommended that future intervention programmes should target parents to reduce the amount of pocket money in China. Copyright © 2013 The Royal Society for Public Health.

    The authors investigated the association between exposure to smoking in movies and the initiation and progression of adolescent smoking over time among 6,522 U.S. adolescents (between the ages of 10 and 14 years, at baseline) in a nationally representative, 4-wave random-digit-dial telephone survey. They conducted a hazard (survival) analysis testing whether exposure to movie smoking and demographic, personality, social, and structural factors predict (a) earlier smoking onset and (b) faster transition to experimental (1–99 cigarettes/lifetime) and established smoking (>100 cigarettes/lifetime). Results suggest that higher exposure to movie smoking is associated with less time to trying cigarettes for the first time (adjusted hazard ratio = 1.66; 95% CI [1.37, 2.01]) but not with faster escalation of smoking behavior following initiation (adjusted hazard ratio = 1.53; 95% CI [0.84, 2.79]). In contrast, age, peer smoking, parenting style, and availability of cigarettes in the home were predictors of earlier onset and faster transition to established smoking. Thus, the authors concluded that the effect of exposure to mass-mediated images of smoking in movies may decline once adolescents have started to smoke, whereas peers and access to tobacco remain influential.

    This paper characterizes historical and current tobacco specific nitrosamine (TSNA) levels in mainstream (MS) cigarette smoke of US commercial cigarettes. To conduct this analysis, we gathered 35 years of published data of 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK) and N-nitrosonornicotine (NNN) levels in MS cigarette smoke. We also assessed internal data of MS smoke NNK and NNN levels generated from various market monitoring initiatives and from control cigarettes used in a multi-year program for testing cigarette ingredients. In all, we analyzed machine smoking data from 401 cigarette samples representing a wide range of products and design characteristics from multiple manufacturers and market leaders. There was no indication that TSNA levels systematically increased in cigarette MS smoke over the 35-year analysis period. In particular, TSNA levels expressed as either per cigarette or normalized for tar suggest a downward trend in MS smoke over the past 10 years. The apparent downward trend in TSNA levels in MS smoke may reflect industry and agricultural community efforts to reduce levels of TSNAs in tobacco and cigarette smoke. Copyright © 2013 Elsevier Inc.

    E-cigarettes (Electronic Nicotine Delivery Systems, or ENDS) are an increasingly popular tobacco product among youth. Some evidence suggests that e-cigarettes may be effective for harm reduction and smoking cessation, although these claims remain controversial. Little is known about how nicotine dependence may contribute to e-cigarettes' effectiveness in reducing or quitting conventional smoking. A cohort of young adults were surveyed over 4 years (approximately ages 19-23). Varying-coefficient models (VCMs) were used to examine the relationship between e-cigarette use and conventional smoking frequency, and how this relationship varies across users with different nicotine dependence levels. Lifetime, but not recent, e-cigarette use was associated with less frequent concurrent smoking of conventional cigarettes among those with high levels of nicotine dependence. However, nondependent e-cigarette users smoked conventional cigarettes slightly more frequently than those who had never used e-cigarettes. Nearly half of ever e-cigarette users reported using them to quit smoking at the last measurement wave. For those who used e-cigarettes in a cessation attempt, the frequency of e-cigarette use was not associated with reductions in future conventional smoking frequency. These findings offer possible support that e-cigarettes may act as a smoking reduction method among highly nicotine-dependent young adult cigarette smokers. However, the opposite was found in non-dependent smokers, suggesting that e-cigarette use should be discouraged among novice tobacco users. Additionally, although a substantial proportion of young adults used e-cigarettes to help them quit smoking, these self-initiated quit attempts with e-cigarettes were not associated with future smoking reduction or cessation. This study offers potential support for e-cigarettes as a smoking reduction tool among highly nicotine-dependent young adult conventional smokers, although the extent and nature of this

    Our objective was to improve understanding of the differences in use behavior and exposure when smoking menthol and non-menthol cigarettes using a 2-part cross-over design. Adult daily smokers were assigned randomly to alternate between 2 weeks of exclusively smoking a menthol test cigarette or a non-menthol test cigarette. Urine and saliva were collected for biomarker measurements; carbon monoxide (CO) was measured, and participants smoked test cigarettes through a CreSS® smoking topography device during 3 clinic visits. Participants turned in their cigarette butts from the test periods for determination of mouth level nicotine and completed subjective questionnaires related to the test cigarettes. Regardless of cigarette preference, participants had higher salivary cotinine when smoking the non-menthol test cigarette, but there were no significant differences detected in urine 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol between the 2 test cigarettes. Mouth level nicotine, puff volume, and puff duration were significantly higher when smoking the menthol brand. Both menthol and non-menthol smokers reported significantly lower enjoyment and satisfaction scores for test cigarettes compared with their brand of choice. Our results suggest that mentholation has an effect on measures of smoking behavior and that mouth level nicotine is a useful indicator of between-brand smoke exposure.

    Enforcement of legislation restricting retail access to tobacco is increasingly relied on to reduce adolescent smoking rates. In 1996, health authorities in the Northern Sydney Health Area began monitoring tobacco retailer compliance (PROOF program) with staged purchase attempts by adolescents below the legal age (18 years). Repeat cross-sectional surveys before (1995) and after (2000) the introduction of PROOF monitored changes in adolescent smoking behaviour. Students aged 12 to 17 years from 11 Northern Sydney metropolitan public secondary schools were surveyed for self-reported smoking and tobacco purchasing behavior in 1995 (n = 5,206) and 2000 (n = 4,120). Between 1996 and 2000, 545 retailer compliance checks found 34% unlawfully sold cigarettes to minors and 28% of these repeated the offence. Nine prosecutions resulted. Modelling revealed a significant association between the intervention and never having smoked (adjusted OR = 1.16, 95% CI = 1.01-1.33) although there was no significant association with being a current smoker. The odds of being a smoker were greater for students from coeducational schools, with this effect being modified by gender. There was no reduction in adolescent smoking with active enforcement of tobacco access laws despite an apparent increase in students who reported never to have smoked.

    Clinical studies indicate that smoking combustible cigarettes promotes progression of renal and cardiac injury, leading to functional decline in the setting of chronic kidney disease (CKD). However, basic studies using in vivo small animal models that mimic clinical pathology of CKD are lacking. To address this issue, we evaluated renal and cardiac injury progression and functional changes induced by 4 wk of daily combustible cigarette smoke exposure in the 5/6th partial nephrectomy (PNx) CKD model. Molecular evaluations revealed that cigarette smoke significantly (P < 0.05) decreased renal and cardiac expression of the antifibrotic microRNA miR-29b-3 and increased expression of molecular fibrosis markers. In terms of cardiac and renal organ structure and function, exposure to cigarette smoke led to significantly increased systolic blood pressure, cardiac hypertrophy, cardiac and renal fibrosis, and decreased renal function. These data indicate that decreased expression of miR-29b-3p is a novel mechanism wherein cigarette smoke promotes accelerated cardiac and renal tissue injury in CKD. (155 words) PMID:27789733

    Alternative cigarette-like nicotine delivery systems have been met with diverse opinions. One concern has been for the effect on children. We investigate whether children can differentiate tobacco cigarette smoking from use of a nicotine inhaler and electronic cigarette. Their opinions on these devices was also of interest. Two structured focus groups and twelve individual interviews were conducted with twenty Māori and Pacific children (6-10 years old) in low socioeconomic areas in Auckland, New Zealand. Children viewed short video clips on an iPad that demonstrated an actor smoking a tobacco cigarette, sucking a lollipop or using an electronic cigarette or a nicotine inhaler. Children did not recognise the inhaler or electronic cigarette. Some children did however notice anomalies in the 'smoking' behaviour. Once told about the products the children were mostly positive about the potential of the inhaler and electronic cigarette to assist smokers to quit. Negative perceptions were expressed, including views about the ill health effects associated with continued nicotine intake and the smoker's inability to quit. In a context unfamiliar with electronic cigarettes or nicotine inhalers, such as New Zealand, children may misperceive use of these products as smoking. Once these products are more common and the purpose of them is known, seeing people use them should normalise quitting behaviour, something the children were very supportive of.

    To determine whether the effect of movie exposure to smoking on adolescent smoking onset is mediated through increased affiliation with peers who smoke. A longitudinal study was conducted with a sample of 5th- 8th graders; persons who were nonsmokers at the baseline assessment (N = 2,614) were followed up 18 months later. Movie exposure to smoking cues was assessed at baseline with a rigorous coding procedure. A school-based survey and follow-up telephone interview determined whether the participant smoked cigarettes. Longitudinal structural modeling analysis indicated movie-smoking exposure was related to smoking onset both through an indirect effect involving increased affiliation with peer smokers and through a direct effect. The analysis controlled for demographics, parenting style, rebelliousness and sensation seeking, school performance, parental smoking, and sibling smoking; several of these variables also had mediated or direct effects to smoking onset. The effect of movie exposure on adolescent smoking onset is attributable in part to a social mechanism. Implications of media effects for prevention are discussed.

    Introduction: Since 2004, several jurisdictions have mandated that cigarettes show reduced ignition propensity (RIP) in laboratory testing. RIP cigarettes may limit fires caused by smoldering cigarettes, reducing fire-related deaths and injury. However, some evidence suggests that RIP cigarettes emit more carbon monoxide and polycyclic aromatic hydrocarbons, and smokers may alter their smoking patterns in response to RIP cigarettes. Both of these could increase smokers’ exposures to harmful constituents in cigarettes. Methods: An 18-day switching study with a comparison group was conducted in Boston, MA (N = 77), and Buffalo, NY (N = 83), in 2006–2007. Current daily smokers completed 4 laboratory visits and two 48-hr field data collections. After a 4-day baseline, Boston participants switched to RIP cigarettes for 14 days, whereas Buffalo participants smoked RIP cigarettes throughout. Outcome measures included cigarettes smoked per day; smoking topography; salivary cotinine; breath CO; and hydroxylated metabolites of pyrene, naphthalene, phenanthrene, and fluorene. Because the groups differed demographically, analyses adjusted for race, age, and sex. Results: We observed no significant changes in smoking topography or CO exposure among participants who switched to RIP cigarettes. Cigarette use decreased significantly in the switched group (37.7 cigarettes/48 hr vs. 32.6 cigarettes/48 hr, p = .031), while hydroxyphenanthrenes increased significantly (555 ng/g creatinine vs. 669 ng/g creatinine, p = .007). No other biomarkers were significantly affected. Discussion: Small increases in exposure to phenanthrene among smokers who switched to RIP versions were observed, while other exposures and smoking topography were not significantly affected. Toxicological implications of these findings are unclear. These findings should be weighed against the potential public health benefits of adopting RIP design standards for cigarette products.

    Multiple studies have demonstrated an association between cigarette smoking and increased anxiety symptoms or disorders, with early life exposures potentially predisposing to enhanced anxiety responses in later life. Explanatory models support a potential role for neurotransmitter systems, inflammation, oxidative and nitrosative stress, mitochondrial dysfunction, neurotrophins and neurogenesis, and epigenetic effects, in anxiety pathogenesis. All of these pathways are affected by exposure to cigarette smoke components, including nicotine and free radicals. This review critically examines and summarizes the literature exploring the role of these systems in increased anxiety and how exposure to cigarette smoke may contribute to this pathology at a biological level. Further, this review explores the effects of cigarette smoke on normal neurodevelopment and anxiety control, suggesting how exposure in early life (prenatal, infancy, and adolescence) may predispose to higher anxiety in later life. A large heterogenous literature was reviewed that detailed the association between cigarette smoking and anxiety symptoms and disorders with structural brain changes, inflammation, and cell-mediated immune markers, markers of oxidative and nitrosative stress, mitochondrial function, neurotransmitter systems, neurotrophins and neurogenesis. Some preliminary data were found for potential epigenetic effects. The literature provides some support for a potential interaction between cigarette smoking, anxiety symptoms and disorders, and the above pathways; however, limitations exist particularly in delineating causative effects. The literature also provides insight into potential effects of cigarette smoke, in particular nicotine, on neurodevelopment. The potential treatment implications of these findings are discussed in regards to future therapeutic targets for anxiety. The aforementioned pathways may help mediate increased anxiety seen in people who smoke. Further research into the

    We examined whether tobacco manufacturers manipulate the menthol content of cigarettes in an effort to target adolescents and young adults. We analyzed data from tobacco industry documents describing menthol product development, results of laboratory testing of US menthol brands, market research reports, and the 2006 National Survey on Drug Use and Health. The tobacco industry attracted new smokers by promoting cigarettes with lower menthol content, which were popular with adolescents and young adults, and provided cigarettes with higher menthol content to long-term smokers. Menthol cigarette sales remained stable from 2000 to 2005 in the United States, despite a 22% decline in overall packs sold. Tobacco companies manipulate the sensory characteristics of cigarettes, including menthol content, thereby facilitating smoking initiation and nicotine dependence. Menthol brands that have used this strategy have been the most successful in attracting youth and young adult smokers and have grown in popularity.

    To investigate cigarette smoking prevalence and exposure to various forms of cigarette marketing among students in 10 African countries. We used data collected during 2009-2011 from the Global Youth Tobacco Survey (GYTS), a school-based cross-sectional survey of students aged 13-15years, to measure the prevalence of cigarette smoking and exposure to cigarette marketing; comparisons to estimates from 2005 to 2006 were conducted for five countries where data were available. Current cigarette smoking ranged from 3.4% to 13.6% among students aged 13-15 in the 10 countries studied, although use of tobacco products other than cigarettes was more prevalent in all countries except in Cote D'Ivoire. Cigarette smoking was higher among boys than girls in seven out of the 10 countries. Among the five countries with two rounds of surveys, a significant decrease in cigarette smoking prevalence was observed in Mauritania and Niger; these two countries also experienced a decline in three measures of cigarette marketing exposure. It is also possible that smoking prevalence might have risen faster among girls than boys. Cigarette smoking among youth was noticeable in 10 African countries evaluated, with the prevalence over 10% in Cote D'Ivoire, Mauritania, and South Africa. Cigarette marketing exposure varied by the types of marketing; traditional venues such as TV, outdoor billboards, newspapers, and magazines were still prominent. Published by Elsevier Inc.

    It has been indicated that acute active and passive tobacco cigarette smoking may cause changes on redox status balance that may result in significant pathologies. However, no study has evaluated the effects of active and passive e-cigarette smoking on redox status of consumers. To examine the acute effects of active and passive e-cigarette and tobacco cigarette smoking on selected redox status markers. Using a randomized single-blind crossover design, 30 participants (15 smokers and 15 nonsmokers) were exposed to three different experimental conditions. Smokers underwent a control session, an active tobacco cigarette smoking session (smoked 2 cigarettes within 30-min) and an active e-cigarette smoking session (smoked a pre-determined number of puffs within 30-min using a liquid with 11 ng/ml nicotine). Similarly, nonsmokers underwent a control session, a passive tobacco cigarette smoking session (exposure of 1 h to 23 ± 1 ppm of CO in a 60 m(3) environmental chamber) and a passive e-cigarette smoking session (exposure of 1 h to air enriched with pre- determined number of puffs in a 60 m(3) environmental chamber). Total antioxidant capacity (TAC), catalase activity (CAT) and reduced glutathione (GSH) were assessed in participants' blood prior to, immediately after, and 1-h post-exposure. TAC, CAT and GSH remained similar to baseline levels immediately after and 1-h-post exposure (p > 0.05) in all trials. Tobacco and e-cigarette smoking exposure do not acutely alter the response of the antioxidant system, neither under active nor passive smoking conditions. Overall, there is not distinction between tobacco and e-cigarette active and passive smoking effects on specific redox status indices.

    Increased prevalence of nicotine dependence among individuals suffering from posttraumatic stress disorder (PTSD) is well established. However, there are limited studies on the prevalence of smoking during pregnancy in relation to prepregnancy history of trauma exposures and active PTSD symptoms during pregnancy. Prenatal smoking has been implicated in a host of negative outcomes for mother and baby. Given maternal and fetal risk, it is critical to define predictors of continued cigarette smoking during pregnancy. Pregnant women from an urban perinatal clinic completed an anonymous survey of trauma history using a modified Traumatic Life Events Questionnaire (TLEQ), PTSD symptoms using the PTSD Symptom Checklist-Civilian Version (PCL-C) and current and past smoking behavior. Those who smoked any number of cigarettes per day after pregnancy confirmation were considered to be "pregnant smokers." Of 218 women who completed the survey, 34 (15.6%) reported smoking cigarettes after confirmation of pregnancy. In unadjusted models, trauma exposure that resulted in fear, helplessness, or horror (FHH), as well as current PTSD symptom severity and probable PTSD diagnosis showed statistical significance as predictors of smoking during pregnancy. After adjusting for age only, PTSD symptoms retained their significant association with smoking during pregnancy. When history of smoking at least five cigarettes per day was added to our models, none of the associations remained significant. These findings emphasize the importance of the behavioral response to past traumatic exposures in influencing cigarette smoking behavior before pregnancy. Given such behaviors enhance risk for continued tobacco use during pregnancy, a trauma-informed approach to smoking cessation in preconception care may ultimately reduce the likelihood of smoking during pregnancy and requires further study.

    Designed to mimic the look and feel of tobacco cigarettes, electronic cigarettes (e-cigarettes) may facilitate smoking cessation. However, the efficacy and safety of e-cigarette use for this purpose remain poorly understood. Our objectives were to review the available data on the efficacy and safety of e-cigarettes for smoking cessation and to consider issues relevant to the context in which they are used, including product awareness and regulatory and ethical concerns. We systematically searched PubMed for randomized controlled trials and uncontrolled, experimental studies involving e-cigarettes. Included studies were limited to English or French language reports. Quality assessment was performed according to the Cochrane Risk of Bias tool. We identified 169 publications, of which 7 studies were included. Studies have concluded that e-cigarettes can help reduce the number of cigarettes smoked and may be as effective for smoking cessation as the nicotine patch. Although there is a lack of data concerning the safety and efficacy of e-cigarettes as a smoking cessation therapy, available evidence showed no significant difference in adverse event rates between e-cigarettes and the nicotine patch. E-cigarettes are widely used among smokers attempting to quit. However, significant international variation remains in the regulatory mechanisms governing the sale and distribution of e-cigarettes. Ethical concerns surround the use of e-cigarettes among minors and their potential to undermine efforts to reduce cigarette smoking. Given the limited available evidence on the risks and benefits of e-cigarette use, large, randomized, controlled trials are urgently needed to definitively establish their potential for smoking cessation.

    Susceptibility to smoke has been recognized as a strong predictor of smoking experimentation and taking up regular smoking habit. The identification of smoking susceptible individuals and its determinants is important in the efforts to reduce future smoking prevalence. The aims of this study are to estimate prevalence of susceptibility to smoke among adolescents, and identify factors associated with it. Cross sectional data was obtained from Global Youth Tobacco Survey conducted in three cities of Pakistan in year 2004. Study population consisted of students in grades, 8th, 9th, and 10th; aged 13 to 15 years. Secondary analysis using univariate and multivariate logistic regression analyses were performed to estimate the associations between smoking susceptibility and co-variates. Descriptive statistics were reported in proportions, and adjusted odds ratios with 95% confidence interval were used to report logistic regression analyses. Approximately 12% of nonsmoking students were found susceptible to smoking. Students, who were females (OR = 1.53, 95% CI [1.24-1.89]); whose parents (OR = 1.64, 95% CI [1.35-1.99]); or close friend smoked (OR = 2.77, 95% CI [2.27- 3.40]) were more susceptible to cigarette smoking. Students who had good knowledge about harmful effects of smoking (OR = 0.54, 95% CI [0.43-0.69]); and had access to anti-smoking media (OR = 0.73, 95% CI [0.59-0.89]) were less likely to be susceptible to smoking. Students who were females, had smoking parents, friends or exposure to newspaper/magazines cigarette marketing, were more susceptible to cigarette smoking among Pakistani adolescents. While knowledge of harmful effects of smoking and access to anti-smoking media served as protective factors against susceptibility to smoking.

    Background Menthol can mask the harshness and taste of tobacco, making menthol cigarettes easier to use and increasing their appeal among vulnerable populations. The tobacco industry has targeted youth, women, and racial minorities with menthol cigarettes, and these groups smoke menthol cigarettes at higher rates. The tobacco industry has also targeted the lesbian, gay, bisexual, and transgender (LGBT) communities with tobacco product marketing. Purpose To assess current menthol cigarette smoking by sexual orientation among a nationally representative sample of U.S. adults. Methods Data were obtained from the 2009–2010 National Adult Tobacco Survey, a national landline and cellular telephone survey of non-institutionalized U.S. adults aged ≥18 years, to compare current menthol cigarette smoking between LGBT (n=2,431) and heterosexual/straight (n=110,841) adults. Data were analyzed during January–April 2014 using descriptive statistics and logistic regression adjusted for sex, age, race, and educational attainment. Results Among all current cigarette smokers, 29.6% reported usually smoking menthol cigarettes in the past 30 days. Menthol use was significantly higher among LGBT smokers, with 36.3% reporting that the cigarettes they usually smoked were menthol compared to 29.3% of heterosexual/straight smokers (p<0.05); this difference was particularly prominent among LGBT females (42.9%) compared to heterosexual/straight women (32.4%) (p<0.05). Following adjustment, LGBT smokers had greater odds of usually smoking menthol cigarettes than heterosexual/straight smokers (OR=1.31, 95% CI=1.09, 1.57). Conclusions These findings suggest that efforts to reduce menthol cigarette use may have the potential to reduce tobacco use and tobacco-related disease and death among LGBT adults. PMID:25245795

    The purpose of this cross-sectional study was to examine the impact of personality factors (neuroticism, extraversion, openness, agreeableness, and conscientiousness), cognitive factors (sense of coherence and self-efficacy), coping resources (family and friend social support) and demographic factors (gender and ethnicity) on cigarette smoking behaviors (initiation, frequency, and amount of cigarette smoking) among college students. A total of 161 U.S. college students, aged 18–26, who enrolled in an introductory psychology course completed self-report questionnaires. The majority of the students had tried smoking (55%); among those who had tried, 42% were current smokers. The majority (77%) who had smoked a whole cigarette did so at age 16 years or younger. Students who reported lower levels of conscientiousness and self-efficacy had a greater likelihood to had tried cigarette smoking. Also, students who had lower levels of self-efficacy reported smoking more frequently and greater quantities of cigarettes than students with higher levels of self-efficacy. Self-efficacy was the most significant predictor of smoking behaviors. Health promotion programs focused on self-efficacy may be an effective tool for reducing the initiation, frequency, and amount of cigarette smoking among college students. PMID:19570288

  10. Reinforcing effects of cigarette advertising on under-age smoking.

    Interviews were conducted with 848 Glasgow children aged between 11 and 14 years. There were consistent differences between smokers and non-smokers. Smokers tended to be more adept at recalling, recognizing and identifying cigarette advertisements. This suggests they tend to pay more attention to cigarette advertising. Smokers also tended to be generally more appreciative of cigarette advertising. Moreover, this greater awareness and appreciation of cigarette advertising was independent of other important predictors of under-age smoking, such as smoking by peers, siblings and parents. These findings, taken in conjunction with previous research, indicate that cigarette advertising is reinforcing under-age smoking. The smokers showed an enhanced or heightened preference for Kensitas Club, the brand favoured by adults. This is consistent with previous research indicating that promotional devices which help determine and reinforce adult cigarette brand preferences have an even greater effect on under-age smokers.

    Abstract Electronic cigarettes (E-cigarettes) are a potential means of addressing the harm to public health caused by tobacco smoking by offering smokers a less harmful means of receiving nicotine. As e-cigarettes are a relatively new phenomenon, there are limited scientific data on the longer-term health effects of their use. This study describes a robust in vitro method for assessing the cytotoxic response of e-cigarette aerosols that can be effectively compared with conventional cigarette smoke. This was measured using the regulatory accepted Neutral Red Uptake assay modified for air–liquid interface (ALI) exposures. An exposure system, comprising a smoking machine, traditionally used for in vitro tobacco smoke exposure assessments, was adapted for use with e-cigarettes to expose human lung epithelial cells at the ALI. Dosimetric analysis methods using real-time quartz crystal microbalances for mass, and post-exposure chemical analysis for nicotine, were employed to detect/distinguish aerosol dilutions from a reference Kentucky 3R4F cigarette and two commercially available e-cigarettes (Vype eStick and ePen). ePen aerosol induced 97%, 94% and 70% less cytotoxicity than 3R4F cigarette smoke based on matched EC50 values at different dilutions (1:5 vs. 1:153 vol:vol), mass (52.1 vs. 3.1 μg/cm2) and nicotine (0.89 vs. 0.27 μg/cm2), respectively. Test doses where cigarette smoke and e-cigarette aerosol cytotoxicity were observed are comparable with calculated daily doses in consumers. Such experiments could form the basis of a larger package of work including chemical analyses, in vitro toxicology tests and clinical studies, to help assess the safety of current and next generation nicotine and tobacco products.

    Acrylamide is a "probably human carcinogen" monomer that can form in heated starchy food as a result of a reaction between asparagine and reducing sugars via Maillard reaction. The main source of acrylamide in human diet are potato products, cereal products and coffee. Tobacco smoke may be another significant source of exposure to acrylamide. The aim of our study was to determine acrylamide content in cigarettes available on the Polish market and to estimate the exposure to acrylamide originating from tobacco smoke in smokers in Poland. The material was cigarettes of the top five brands bought in Poland and tobacco from non-smoked cigarettes. Acrylamide content in cigarettes mainstream smoke was determined by LC-MS/MS. Exposure assessment was carried out using analytical data of acrylamide content in cigarettes and the mean quantity of cigarettes smoked daily by smokers in Poland, assuming body weight at 70 kg. The mean content of acrylamide was 679.3 ng/cigarette (range: 455.0 - 822.5 ng/cigarette). The content of acrylamide was evidenced to correlate positively with total particulate matter (TPM) content in cigarettes. The estimated average exposure to acrylamide from tobacco smoke in adult smokers in Poland is 0.17 μg/kg b.w./day. Our results demonstrate that tobacco smoke is a significant source of acrylamide and total exposure to acrylamide in the population of smokers, on average, is higher by more than 50% in comparison with non-smokers. Our estimation of exposure to acrylamide from tobacco smoke is the first estimation taking into account the actual determined acrylamide content in the cigarettes available on the market.

    Chronic cigarette smoking is associated with adverse effects on cardiac, pulmonary, and vascular function as well as the increased risk for various forms of cancer. However, little is known about the effects of chronic smoking on human brain function. Although smoking rates have decreased in the developed world, they remain high in individuals with alcohol use disorders (AUD) and other neuropsychiatric conditions. Despite the high prevalence of chronic smoking in AUD, few studies have addressed the potential neurobiological or neurocognitive consequences of chronic smoking in alcohol use disorders. Here, we review the the neurobiological and neurocognitive findings in both AUD and chronic cigarette smoking, followed by a review of the effects of comorbid cigarette smoking on neurobiology and neurocognition in AUD. Recent research suggests that comorbid chronic cigarette smoking modulates magnetic resonance-detectable brain injury and neurocognition in alcohol use disorders and adversely affects neurobiological and neurocognitive recovery in abstinent alcoholics.. Consideration of the potential separate and interactive effects of chronic smoking and alcohol use disorders may have significant implications for pharmacological and behavioral treatment interventions.

    Today the uptake of smoking is primarily an adolescent pursuit. Awareness of tobacco advertising and promotion is high, and evidence suggests that it plays a role in adolescent smoking uptake. We evaluated the influence of tobacco advertising and promotion and exposure to smokers on never-smoking adolescents' susceptibility to smoking. We used data on 3536 adolescent never smokers (those who had never even puffed on a cigarette) from the 1993 California Tobacco Survey. That survey questioned adolescents about smoking history and inclinations. For this analysis, we defined as susceptible to smoking those never smokers who said on the survey that they could not rule out independently deciding to try a cigarette soon or smoking one offered by a friend. Also for this analysis, we devised two indices: 1) a 5-point index of an individual's receptivity to tobacco advertising as determined by the number of positive responses to five survey items (recognition of advertising messages, having a favorite advertisement, naming a brand he/she might buy, owning a tobacco-related promotional item, and willingness to use a tobacco-related promotional item) and 2) an index classifying an individual's reported exposure to family and peer smoking into one of four levels. Using logistic regression, we assessed the independent importance of our indices in predicting susceptibility to smoking after adjustment for sociodemographic variables, including age, sex, and race/ethnicity, and for perceived school performance. Tests of statistical significance were two-sided. Receptivity to tobacco advertising and exposure to smokers were independently associated with susceptibility to smoking, but the relationship appeared stronger for receptivity to advertising. Adolescents exposed to family members and peers (n = 489) who smoked were 1.89 (95% confidence interval [CI] = 1.30-2.74) times as likely to be susceptible, whereas adolescents who scored 4 or more on the Index of Receptivity to Tobacco

    Depressive symptoms are associated with increased levels of cigarette smoking, yet not every individual experiencing depressive symptoms smokes. This study examined whether religious coping moderated the impact of depressive symptoms on past 30-day cigarette use among a racially/ethnically diverse sample of 963 post-secondary vocational students (46.8% women; mean age = 25 years). Results from negative binomial regression analyses indicated that depressive symptoms increased the likelihood of cigarette smoking (quantity-frequency measure of cigarette use) for female students, whereas positive religious coping decreased the likelihood of smoking for female students. Consistent with religious coping theory and as expected, negative religious coping moderated the depressive symptoms-smoking relationship such that negative religious coping exacerbated the impact of depressive symptoms on cigarette smoking among females. Positive religious coping also moderated the depressive symptoms-cigarette smoking relationship for females. However, contrary to expectations, high levels of positive religious coping exacerbated the likelihood of cigarette smoking among females with high levels of depressive symptoms. Surprisingly, neither depressive symptoms nor positive or negative religious coping contributed to the likelihood of males’ smoking. Study limitations and suggestions for directions in future research are discussed. PMID:23276324

Adolescents from 20 middle and high schools in Minneapolis/St Paul, MN completed classroom-administered surveys. A total of 2,793 adolescents (53.2% girls) in grades 6-12. Beverage patterns; breakfast frequency; moderate to vigorous physical activity (MVPA); media use; sleep; and cigarette smoking. Linear and logistic regression models were used to estimate associations between health behaviors and SED consumption, adjusting for demographics. Over a third of adolescents consumed sports drinks and 14.7% consumed energy drinks at least once a week. Among boys and girls, both sports and energy drink consumption were related to higher video game use; sugar-sweetened beverage and fruit juice intake; and smoking (P < .05). Sports drink consumption was also significantly related to higher MVPA and organized sport participation for both genders (P < .01). Although sports drink consumption was associated with higher MVPA, adolescents should be reminded of recommendations to consume these beverages only after vigorous, prolonged activity. There is also a need for future interventions designed to reduce SED consumption, to address the clustering of unhealthy behaviors. Copyright © 2014 Society for Nutrition Education and Behavior.

    A series of low tar cigarettes (LTC) were smoked and the quantities of condensable mainstream (inhaled) and sidestream (between puffs) smoke compounds were determined and compared to those produced by a high tar, nonfilter cigarette. It was found that the LTC produced large quantities of sidestream smoke condensates, about equal to the high tar cigarette, and contained very high levels of toxic or cocarcinogenic phenols. On an equal weight basis, the LTC emitted more of these hazardous compounds into sidestream and environmental tobacco smoke. Higher smoke yields of a flavor additive and a sugar degradation product indicated addition of suchmore » compounds during the manufacture of LTC. It was concluded that, compared to a high tar cigarette, smoking LTC may be better for the smoker, but not for the nearby nonsmoker. Information should be developed to allow smokers to choose LTC that produce lower levels of hazardous compounds in their environmentally emitted sidestream smoke.« less

    Many studies have shown that cigarette smoking exerts multiple effects on the thyroid gland. Smoking seems to induce changes in thyroid function tests, like decrease in TSH and increase in thyroid hormones. However, these alterations are usually mild. In addition, tobacco smoking may also play a role in thyroid autoimmunity. Many studies have confirmed a significant influence of smoking on Graves' hyperthyroidism and particularly on Graves' orbitopathy. Here, smoking may increase the risk of disease development, may reduce the effectiveness of treatment, and eventually induce relapse. The role of smoking in Hashimoto's thyroiditis is not as well established as in Graves' disease. Nonetheless, lower prevalence of thyroglobulin antibodies, thyroperoxidase antibodies and hypothyroidism were found in smokers. These findings contrast with a study that reported increased risk of hypothyroidism in smokers with Hashimoto's thyroiditis. Moreover, cigarette smoking increases the incidence of multinodular goitre, especially in iodine-deficient areas. Some studies have examined cigarette smoking in relation to the risk of thyroid cancer. Interestingly, many of them have shown that smoking may reduce the risk of differentiated thyroid cancer. Furthermore, both active and passive smoking during pregnancy might modify maternal and foetal thyroid function. This review evaluates the current data concerning the influence of cigarette smoking on thyroid gland, including hormonal changes, autoimmunity and selected diseases. These findings, however, in our opinion, should be carefully evaluated and some of them are not totally evidence-based. Further studies are required to explain the effects of smoking upon thyroid pathophysiology.

    Cigarette smoking is a risk factor for several diseases. There has been a steep increase in the use of e-cigarettes that may offer a safer alternative to cigarette smoking. In vitro models of smoking-related diseases may provide valuable insights into disease mechanisms associated with tobacco use and could be used to assess e-cigarettes. We previously reported the application of a 'scratch wound' assay, measuring endothelial cell migration rate following artificial wounding, in the presence or absence of cigarette smoke extracts. This study reports the comparative effects of two commercial e-cigarette products (Vype ePen and Vype eStick) and a scientific reference cigarette (3R4F) on endothelial migration in vitro. Puff-matched extracts were generated using the Health Canada Intense (HCI) regime for cigarettes and a modified HCI for e-cigarettes. Exposure to 3R4F extract (20h) induced concentration-dependent inhibition of endothelial cell migration, with complete inhibition at concentrations >20%. E-cigarette extracts did not inhibit migration, even at double the 3R4F extract nicotine concentration, allowing cells to migrate into the wounded area. Our data demonstrate that e-cigarettes do not induce the inhibition of endothelial cell migration in vitro when compared to 3R4F. The scratch wound assay enables the comparative assessment between tobacco and nicotine products in vitro. Copyright © 2017 The Authors. Published by Elsevier B.V. All rights reserved.

    Objectives. We evaluated the impact of state tobacco control policies on disparities in maternal smoking during pregnancy. Methods. We analyzed 2000–2010 National Vital Statistics System natality files with 17 699 534 births from 28 states and the District of Columbia that used the 1989 revision of the birth certificate. We conducted differences-in-differences regression models to assess whether changes in cigarette taxes and smoke-free legislation were associated with changes in maternal smoking during pregnancy and number of cigarettes smoked. To evaluate disparities, we included interaction terms between maternal race/ethnicity, education, and cigarette taxes. Results. Although maternal smoking decreased from 11.6% to 8.9%, White and Black women without a high school degree had some of the highest rates of smoking (39.7% and 16.4%, respectively). These same women were the most responsive to cigarette tax increases, but not to smoke-free legislation. For every $1.00 cigarette tax increase, low-educated White and Black mothers decreased smoking by nearly 2 percentage points and smoked between 14 and 22 fewer cigarettes per month. Conclusions. State cigarette taxes may be an effective population-level intervention to decrease racial/ethnic and socioeconomic disparities in maternal smoking during pregnancy. PMID:24922149

    This paper analyses the compensatory behavior of smokers. Exploiting data on cotinine concentration--a metabolite of nicotine--measured in a large population of smokers over time, we show that smokers compensate for tax hikes by extracting more nicotine per cigarette. Our study makes two important contributions. First, as smoking a given cigarette more intensively is detrimental to health, our results question the usefulness of tax increases. Second, we develop a model of rational addiction where agents can also adjust their intensity of smoking, and we show that the previous empirical results suffer from estimation biases.

    PURPOSE Assess the prevalence and correlates of e-cigarette perceptions and trial among adolescents in Mexico, where e-cigarettes are banned. METHODS Cross-sectional data were collected in 2015 from a representative sample of middle school students (n=10,146). Prevalence of e-cigarette awareness, relative harm, and trial were estimated, adjusting for sampling weights and school-level clustering. Multilevel logistic regression models adjusted for school-level clustering to assess correlates of e-cigarette awareness and trial. Finally, students who had tried only e-cigarettes were compared with students who had tried: 1) conventional cigarettes only; 2) both e-cigarettes and conventional cigarettes (dual triers); 3) neither cigarette type (never triers). RESULTS 51% of students had heard about e-cigarettes, 19% believed e-cigarettes were less harmful than conventional cigarettes, and 10% had tried them. Independent correlates of e-cigarette awareness and trial included established risk factors for smoking, as well as technophilia (i.e., use of more media technologies) and greater Internet tobacco advertising exposure. Exclusive e-cigarette triers (4%) had significantly higher technophilia, bedroom Internet access, and Internet tobacco advertising exposure compared to conventional cigarette triers (19%) and never triers (71%), but not compared to dual triers (6%), even though dual triers had significantly stronger conventional cigarette risk factors. CONCLUSIONS This study suggests that adolescent e-cigarette awareness and use is high in Mexico, in spite of its e-cigarette ban. A significant number of medium-risk youth have tried e-cigarettes only, suggesting that e-cigarettes could lead to more intensive substance use. Strategies to reduce e-cigarette use should consider reducing exposures to Internet marketing. PMID:26903433

    Current smoking prevalence in Thailand decreased from 1991 to 2004 and since that time the prevalence has remained flat. It has been suggested that one of the reasons that the prevalence of current smoking in Thailand has stopped decreasing is due to the use of RYO cigarettes. The aim of this study was to examine characteristics of users of manufactured and RYO cigarettes and dual users in Thailand, in order to determine whether there are differences in the characteristics of users of the different products. The 2009 Global Adult Tobacco Survey (GATS Thailand) provides detailed information on current smoking patterns. GATS Thailand used a nationally and regionally representative probability sample of 20,566 adults (ages 15 years and above) who were chosen through stratified three-stage cluster sampling and then interviewed face-to-face. The prevalence of current smoking among Thai adults was 45.6% for men and 3.1% for women. In all, 18.4% of men and 1.0% of women were current users of manufactured cigarettes only, while 15.8% of men and 1.7% of women were current users of RYO cigarettes only. 11.2% of men and 0.1% of women used both RYO and manufactured cigarettes. Users of manufactured cigarettes were younger and users of RYO were older. RYO smokers were more likely to live in rural areas. Smokers of manufactured cigarettes appeared to be more knowledgeable about the health risks of tobacco use. However, the difference was confounded with age and education; when demographic variables were controlled, the knowledge differences no longer remained. Smokers of manufactured cigarettes were more likely than dual users and those who used only RYO to report that they were planning on quitting in the next month. Users of RYO only appeared to be more addicted than the other two groups as measured by time to first cigarette. There appears to be a need for product targeted cessation and prevention efforts that are directed toward specific population subgroups in Thailand and

    Tobacco use is one of the greatest public health problems worldwide and the hazards of cigarette smoking to public health call for better recognition of cigarette smoking behaviors to guide evidence-based policy. Protection motivation theory (PMT) provides a conceptual framework to investigate tobacco use. Evidence from diverse sources implies that the dynamics of smoking behavior may be quantum in nature, consisting of an intuition and an analytical process, challenging the traditional linear continuous analytical approach. In this study, we used cusp catastrophe, a nonlinear analytical approach to test the dual-process hypothesis of cigarette smoking. Data were collected from a random sample of vocational high school students in China ( n = 528). The multivariate stochastic cusp modeling was used and executed with the Cusp Package in R. The PMT-based Threat Appraisal and Coping Appraisal were used as the two control variables and the frequency of cigarette smoking (daily, weekly, occasional, and never) in the past month was used as the outcome variable. Consistent with PMT, the Threat Appraisal (asymmetry, α 1 = 0.1987, p < 0.001) and Coping Appraisal (bifurcation, β 2 = 0.1760, p < 0.05) significantly predicted the smoking behavior after controlling for covariates. Furthermore, the cusp model performed better than the alternative linear and logistic regression models with regard to higher R 2 (0.82 for cusp, but 0.21 for linear and 0.25 for logistic) and smaller AIC and BIC. Study findings support the conclusion that cigarette smoking in adolescents is a quantum process and PMT is relevant to guide studies to understand smoking behavior for smoking prevention and cessation.

  6. Biological effects of cigarette smoke, wood smoke, and the smoke from plastics: the use of electron spin resonance.

    Pryor, W A

    1992-12-01

    This review compares and contrasts the chemistry of cigarette smoke, wood smoke, and the smoke from plastics and building materials that is inhaled by persons trapped in fires. Cigarette smoke produces cancer, emphysema, and other diseases after a delay of years. Acute exposure to smoke in a fire can produce a loss of lung function and death after a delay of days or weeks. Tobacco smoke and the smoke inhaled in a burning building have some similarities from a chemical viewpoint. For example, both contain high concentrations of CO and other combustion products. In addition, both contain high concentrations of free radicals, and our laboratory has studied these free radicals, largely by electron spin resonance (ESR) methods, for about 15 years. This article reviews what is known about the radicals present in these different types of smokes and soots and tars and summarizes the evidence that suggests these radicals could be involved in cigarette-induced pathology and smoke-inhalation deaths. The combustion of all organic materials produces radicals, but (with the exception of the smoke from perfluoropolymers) the radicals that are detected by ESR methods (and thus the radicals that would reach the lungs) are not those that arise in the combustion process. Rather they arise from chemical reactions that occur in the smoke itself. Thus, a knowledge of the chemistry of the smoke is necessary to understand the nature of the radicals formed. Even materials as similar as cigarettes and wood (cellulose) produce smoke that contains radicals with very different lifetimes and chemical characteristics, and mechanistic rationales for this are discussed. Cigarette tar contains a semiquinone radical that is infinitely stable and can be directly observed by ESR. Aqueous extracts of cigarette tar, which contain this radical, reduce oxygen to superoxide and thus produce both hydrogen peroxide and the hydroxyl radical. These solutions both oxidize alpha-1-proteinase inhibitor (a1PI) and

    OBJECTIVE: To describe a new murine model of cigarette smoke-induced emphysema. METHODS: Twenty-four male Wistar rats were divided into two groups: the cigarette smoke group, comprising 12 rats exposed to smoke from 12 commercial filter cigarettes three times a day (a total of 36 cigarettes per day) every day for 30 weeks; and the control group, comprising 12 rats exposed to room air three times a day every day for 30 weeks. Lung function was assessed by mechanical ventilation, and emphysema was morphometrically assessed by measurement of the mean linear intercept (Lm). RESULTS: The mean weight gain was significantly (approximately ten times) lower in the cigarette smoke group than in the control group. The Lm was 25.0% higher in the cigarette smoke group. There was a trend toward worsening of lung function parameters in the cigarette smoke group. CONCLUSIONS: The new murine model of cigarette smoke-induced emphysema and the methodology employed in the present study are effective and reproducible, representing a promising and economically viable option for use in studies investigating the pathophysiology of and therapeutic approaches to COPD.

    Cigarette smoking may affect each of the currently proposed mechanisms of ovarian carcinogenesis. Whether cigarette smoking has any effect on the development of ovarian cancer has not been adequately evaluated. To study this issue, the authors examined data from the Cancer and Steroid Hormone Study, a multicenter, case-control study of gynecologic cancers conducted between December 1, 1980, and December 31, 1982, in eight geographic areas of the United States. This analysis utilized data on 494 women with newly diagnosed epithelial ovarian cancer and 4,238 population-based control women 20-54 years of age. There was no association of epithelial ovarian cancer with dose of cigarette smoking, age smoking started, time since smoking started, or time since smoking last occurred. Simultaneous adjustment for age, parity, history of oral contraceptive use, and other potentially confounding factors did not alter these results.

    To evaluate how experienced dual users used cigarettes and e-cigarettes in real-world use and under different levels of cigarette availability. Dual users (cigarettes+e-cigarettes; n=74) and a smoke-only group (just cigarettes; n=74) engaged in a 26-day study with two ad lib use intervals, a week of 75% cigarette reduction and three days of 100% cigarette reduction. After a week of ad lib use of products, all participants were asked to reduce smoking by 75% (dual users were free to use their e-cigarettes as they wished), followed by another week of ad lib use. All participants were then asked to reduce smoking by 100% (cessation) for three days. Primary outcomes were biological samples (carbon monoxide, urinary nicotine and cotinine). Participants also provided real-time reports of product use, craving, and withdrawal symptoms using a smartphone app. Dual users did not smoke fewer cigarettes than smoke-only participants during ad lib periods, but quadrupled their use of e-cigarettes during smoking reduction periods. Dual users were significantly more likely to maintain 100% reduction (97.1% vs. 81.2%). Amongst women, dual use was associated with higher nicotine levels and withdrawal suppression. Among a group of experienced dual users, e-cigarettes helped maintain smoking reduction and reduced some withdrawal symptoms, although both withdrawal symptoms and nicotine levels varied as a function of gender.

Methods Dual users (cigarettes + e-cigarettes; n=74) and a smoke-only group (just cigarettes; n=74) engaged in a 26-day study with two ad lib use intervals, a week of 75% cigarette reduction and three days of 100% cigarette reduction. After a week of ad lib use of products, all participants were asked to reduce smoking by 75% (dual users were free to use their e-cigarettes as they wished), followed by another week of ad lib use. All participants were then asked to reduce smoking by 100% (cessation) for three days. Primary outcomes were biological samples (carbon monoxide, urinary nicotine and cotinine). Participants also provided real-time reports of product use, craving, and withdrawal symptoms using a smartphone app. Results Dual users did not smoke fewer cigarettes than smoke-only participants during ad lib periods, but quadrupled their use of e-cigarettes during smoking reduction periods. Dual users were significantly more likely to maintain 100% reduction (97.1% vs. 81.2%). Amongst women, dual use was associated with higher nicotine levels and withdrawal suppression. Discussion Among a group of experienced dual users, e-cigarettes helped maintain smoking reduction and reduced some withdrawal symptoms, although both withdrawal symptoms and nicotine levels varied as a function of gender.

    Cigarette smoking is an economically and epidemiologically expensive public health concern. Most adult smokers become addicted during adolescence, rendering it a crucial period for prevention and intervention. Although litigation claims have delayed implementation, graphic warning labels proposed by the U.S. Food and Drug Administration (FDA) may be a promising way to achieve this goal. We aimed to determine the efficacy of the labels in reducing in-scanner craving and to characterize the neurobiological responses in adolescent and adult smokers and non-smokers. While undergoing functional magnetic resonance imaging, thirty-nine 13- to 18-year-old adolescent and forty-one 25- to 30-year-old adult smokers and non-smokers rated their desire to smoke when presented with emotionally graphic warning labels and comparison non-graphic labels. Compared with adult smokers, adolescent smokers exhibited greater craving reduction in response to the warning labels. Although smokers evinced overall blunted recruitment of insula and dorsolateral prefrontal cortex (DLPFC) relative to non-smokers, an effect that was stronger in adolescent smokers, parametrically increasing activation of these regions was associated with greater craving reduction. Functional connectivity analyses suggest that greater DLPFC regulation of limbic regions predicted cigarette craving. These data underscore a prominent role of frontoinsular circuitry in predicting the efficacy of FDA graphic warning labels in craving reduction in adult and adolescent smokers. PMID:25887154

    Given that little is known about the price-related cigarette brand preferences of youths, the current study seeks to characterise cigarette brand preferences and examine factors associated with smoking discount or native cigarette brands among Canadian youths who are current smokers. This study used nationally representative data collected from 71,003 grade 5-12 students as part of the 2006-7 Canadian Youth Smoking Survey (YSS). Using data from current smokers, logistic regression models were used to examine factors associated with smoking discount or native cigarette brands relative to premium cigarette brands. In 2006, premium cigarettes were the most prevalent brand of cigarette youths report usually smoking (49.4%); a substantial number of youths do report usually smoking either discount (12.9%) or native (9.3%) cigarette brands. Occasional smokers were more likely to report usually smoking premium cigarettes whereas daily smokers were more likely to report smoking either discount or native cigarettes. In particular, discount and native brands appear to be appealing among smoking youths with less spending money or those who are heavier smokers compared to youths smoking premium brands. Discount and native cigarette brands are commonly used by a substantial number of smoking youths in Canada. Additional research is required to better understand the reasons behind different cigarette brand preferences and how youths are able to access premium, discount and illicit native cigarettes. Moreover, ongoing surveillance of the cigarette brand preferences of youths is required for guiding future tobacco control policy and programming activities.

    In the last decade Poland has successfully carried out effective anti-tobacco campaigns and introduced tobacco control legislation. This comprehensive strategy has focused on the general population and has led to a considerable decrease in tobacco consumption. Prisoners constitute a relatively small part of the entire Polish population and smoking habits in this group have been given little attention. The aim of the study was to assess the prevalence of cigarette smoking in Polish male prisoners, factors determining smoking in this group, prisoners' attitudes towards smoking cessation, and to evaluate prisoners' perception of different anti-tobacco measures. An anonymous questionnaire including personal, demographic and smoking data was distributed among 944 male inmates. Of these, 907 men aged between 17 and 62 years (mean 32.3 years) met the inclusion criteria of the study. For the comparison of proportions, a chi-square test was used with continuity correction whenever appropriate. In the entire group, 81% of the subjects were smokers, 12% - ex-smokers, and 7% - never smokers. Current smokers had significantly lower education level than non-smokers (p < 0.0001) and ever-smokers more frequently abused other psychoactive substances than never smokers (p < 0.0001). Stress was reported as an important factor in prompting smoking (77%). Forty-nine percent of daily smokers were aware of the adverse health consequences of smoking. The majority of smokers (75%) had attempted to quit smoking in the past. Forty percent of smoking prisoners considered an award for abstaining from cigarettes as the best means to limit the prevalence of smoking in prisons. The prevalence of cigarette smoking among Polish prisoners is high. However, a majority of smokers attempt to quit, and they should be encouraged and supported. Efforts to reduce cigarette smoking in prisons need to take into consideration the specific factors influencing smoking habits in prisons.

    Cigarette smoking is highly prevalent among scholars and university students in Jordan. The aim of this study is to discover the environmental factors and social influences that motivate Jordanian students to smoke and to recommend adequate programs in order to stop adolescents from smoking. A questionnaire of (28) items was designed to assess students and professor's attitudes towards smoking, the sample of the study consisted of(851) participants from different levels in a community nearby Al-Isra Private University. The study also attempted to examine the effects of the following factors: social status, age, gender, parental education and mode of spending free time, having parents, siblings, friends and teachers who smoke. The results show that the proportion of smokers to nonsmokers was of (33:67). The first cigarette smoked by 65% of the sample, was before the age of 18 years and 88.5% was before the age of 21 years. The environmental factors and social influences that motivate students to smoke were related to teachers and friends behavior. The major reasons to start smoking were to try something new and Spending free time with friends more than with family. Also Health disturbances suffered by smokers (fatigue, stress, frustration and depression) were as two times greater compared to nonsmokers. Desire to quit smoking among participants were very high and there was a positive correlation between nonsmokers and high level of education. Desire were greatly negative to have smoker mate = 93%, smoker children = 96% or smoker friends = 87%. In conclusion the increased rate of smoking before age of 18 years indicates that smoking prevention programs need to be started at an earlier age. The risk factors of smoking onset are subject to modification and families must be aware of the potential risks of certain ways of spending time and modifying attitudes.

    Introduction: Research demonstrates that cognitive biases toward drug-related stimuli are correlated with substance use. This study aimed to investigate differences in cognitive biases (i.e., approach bias, attentional bias, and memory associations) between smoking and non-smoking adolescents in the US and the Netherlands. Within the group of smokers, we examined the relative predictive value of the cognitive biases and impulsivity related constructs (including inhibition skills, working memory, and risk taking) on daily smoking and nicotine dependence. Method: A total of 125 American and Dutch adolescent smokers (n = 67) and non-smokers (n = 58) between 13 and 18 years old participated. Participants completed the smoking approach–avoidance task, the classical and emotional Stroop task, brief implicit associations task, balloon analog risk task, the self-ordering pointing task, and a questionnaire assessing level of nicotine dependence and smoking behavior. Results: The analytical sample consisted of 56 Dutch adolescents (27 smokers and 29 non-smokers) and 37 American adolescents (19 smokers and 18 non-smokers). No differences in cognitive biases between smokers and non-smokers were found. Generally, Dutch adolescents demonstrated an avoidance bias toward both smoking and neutral stimuli whereas the American adolescents did not demonstrate a bias. Within the group of smokers, regression analyses showed that stronger attentional bias and weaker inhibition skills predicted greater nicotine dependence while weak working memory predicted more daily cigarette use. Conclusion: Attentional bias, inhibition skills, and working memory might be important factors explaining smoking in adolescence. Cultural differences in approach–avoidance bias should be considered in future research. PMID:24904435

    Assess the prevalence and correlates of e-cigarette perceptions and trial among adolescents in Mexico, where e-cigarettes are banned. Cross-sectional data were collected in 2015 from a representative sample of middle-school students (n = 10,146). Prevalence of e-cigarette awareness, relative harm, and trial were estimated, adjusting for sampling weights and school-level clustering. Multilevel logistic regression models adjusted for school-level clustering to assess correlates of e-cigarette awareness and trial. Finally, students who had tried only e-cigarettes were compared with students who had tried: (1) conventional cigarettes only; (2) both e-cigarettes and conventional cigarettes (dual triers); and (3) neither cigarette type (never triers). Fifty-one percent of students had heard about e-cigarettes, 19% believed e-cigarettes were less harmful than conventional cigarettes, and 10% had tried them. Independent correlates of e-cigarette awareness and trial included established risk factors for smoking, as well as technophilia (i.e., use of more media technologies) and greater Internet tobacco advertising exposure. Exclusive e-cigarette triers (4%) had significantly higher technophilia, bedroom Internet access, and Internet tobacco advertising exposure compared to conventional cigarette triers (19%) and never triers (71%) but not compared to dual triers (6%), although dual triers had significantly stronger conventional cigarette risk factors. This study suggests that adolescent e-cigarette awareness and use is high in Mexico, in spite of its e-cigarette ban. A significant number of medium-risk youth have tried e-cigarettes only, suggesting that e-cigarettes could lead to more intensive substance use. Strategies to reduce e-cigarette use should consider reducing exposures to Internet marketing. Copyright © 2016 Society for Adolescent Health and Medicine. Published by Elsevier Inc.

    Cigarette graphic warning labels elicit negative emotion, which increases risk perceptions through multiple processes. We examined whether this emotion simultaneously affects motivated cognitions like smoking myth endorsement (e.g. 'exercise can undo the negative effects of smoking') and perceptions of cigarette danger versus other products. 736 adult and 469 teen smokers/vulnerable smokers viewed one of three warning label types (text-only, low emotion graphic or high emotion graphic) four times over two weeks. Emotional reactions to the warnings were reported during the first and fourth exposures. Participants reported how often they considered the warnings, smoking myth endorsement, risk perceptions and perceptions of cigarette danger relative to smokeless tobacco and electronic cigarettes. In structural equation models, emotional reactions influenced risk perceptions and smoking myth endorsement through two processes. Emotion acted as information about risk, directly increasing smoking risk perceptions and decreasing smoking myth endorsement. Emotion also acted as a spotlight, motivating consideration of the warning information. Warning consideration increased risk perceptions, but also increased smoking myth endorsement. Emotional reactions to warnings decreased perceptions of cigarette danger relative to other products. Emotional reactions to cigarette warnings increase smoking risk perceptions, but also smoking myth endorsement and misperceptions that cigarettes are less dangerous than potentially harm-reducing tobacco products.

    Cigarette smoke is a major exogenous source of free radicals, and the resulting oxidative stress is one of the major causes of smoking-caused diseases. Yet, many of the factors that impact free radical delivery from cigarettes remain unclear. In this study, we machine-smoked cigarettes and measured the levels of gas- and particulate-phase radicals by electron paramagnetic resonance (EPR) spectroscopy using standardized smoking regimens (International Organization of Standardization (ISO) and Canadian Intense (CI)), puffing parameters, and tobacco blends. Radical delivery per cigarette was significantly greater in both gas (4-fold) and particulate (6-fold) phases when cigarettes were smoked under the CI protocol compared to the ISO protocol. Total puff volume per cigarette was the major factor with radical production being proportional to total volume, regardless of whether volume differences were achieved by changes in individual puff volume or puff frequency. Changing puff shape (bell vs sharp vs square) or puff duration (1-5 s), without changing volume, had no effect on radical yields. Tobacco variety did have a significant impact on free radical production, with gas-phase radicals highest in reconstituted > burley > oriental > bright tobacco and particulate-phase radicals highest in burley > bright > oriental > reconstituted tobacco. Our findings show that modifiable cigarette design features and measurable user smoking behaviors are key factors determining free radical exposure in smokers.

    Background Latino smokers are a rising public health concern who experience elevated tobacco related health disparities. Purpose Additional information on Latino smoking is needed to inform screening and treatment. Analysis Latent class analysis using smoking frequency, cigarette preferences, onset, smoking duration, cigarettes per day and minutes to first cigarette were used to create multivariate latent smoking profiles for Latino men and women. Results Final models found seven classes for Latinas and nine classes for Latinos. Despite a common finding in the literature that Latino smokers are more likely to be low-risk, intermittent smokers, the majority of classes, for both males and females, described patterns of high-risk, daily smoking. Gender variations in smoking classes were noted. Conclusions Several markers of smoking risk were identified among both male and female Latino smokers including long durations of smoking, daily smoking and preference for specialty cigarettes, all factors associated with long-term health consequences.

    Many states have banned electronic cigarette sales to minors under the rationale that using e-cigarettes leads to smoking traditional combustion cigarettes. Such sales bans would be counterproductive, however, if e-cigarettes and traditional cigarettes are substitutes, as bans might push teenagers back to smoking the more dangerous combustion cigarettes. We provide evidence that these sales bans reduce the incidence of smoking conventional cigarettes among high school seniors. Moreover, we provide evidence suggesting that sales bans reduced e-cigarette usage as well. This evidence suggests that not only are e-cigarettes and smoking regular cigarettes positively related and not substitutes for young people, banning retail sales to minors is an effective policy tool in reducing tobacco use.
