Abstract

Population-based indicators of smoking cessation have stalled in recent years. This commentary focuses attention on tobacco control policies that can be used to stimulate renewed consumer demand for smoking cessation. Tobacco use as reflected in population trends is the product of the interaction of three broad categories of factors: agent, host, and environment. Government policies are an important, modifıable environmental influence that can directly or indirectly influence smoking behavior. For example, numerous studies have shown that a hike in tobacco taxes reduces cigarette consumption and encourages smokers to quit.

Abstract

Objective: To explore the determinants of willingness to quit smoking among regular smokers, and to provide a scientific basis for establishing smoking cessation strategies for adult smokers.

Methods: The study was conducted between April to August 2006. A stratified multistage cluster sampling design was used to select residents from 10 streets in Shenyang. Households were then randomly selected from the communities of the selected streets. The average of 40 adult smokers were selected from each of 20 communities. The information of age, gender and smoking status was collected from 801 participants.

Results: The rate of voluntary cessation of smoking was 30.7%(29.8% in male and 46.7%in female). The government employees had the highest proportion of voluntary cessation of smoking (47.5%), followed by retired population (36.7%) and technical professionals (21.4%). The associated factors of smoking cessation include objection from relatives, public opinion, the advocacy efforts and measures of tobacco control.

Conclusion: The proportion of voluntary smoking cessation was low in Shenyang. Additional advocacy efforts and control measures should be taken to encourage the cessation of smoking.

Abstract

This study examined the degree to which legislation intended to reduce the incidence of cigarette-caused fires influenced the behaviours of a cohort of smokers in Ontario. A random digit dialled telephone survey of adult smokers residing in Ontario was conducted in 2005, ending 1 month prior to the reduced ignition propensity (RIP) regulation's implementation date. A follow-up survey was conducted one year later. Of the baseline participants, 73.0% (n=435) completed the follow-up survey. The frequency of fire risk behaviours was similar across both surveys. At baseline, only 3.7% of smokers interviewed reported that their cigarettes went out on their own 'often' while smoking. Following the implementation of the reduced ignition propensity legislation, this increased significantly to 14.7%. Results suggest that the proportion of Ontario smokers who reported engaging in behaviour such as leaving a cigarette burning unattended and smoking in bed actually declined, although these declines were not statistically significant across all measures of fire risk.

Assessing the impact of cigarette package health warning labels: A cross-country comparison in Brazil, Uruguay and Mexico. Salud Publica de Mexico, 52(Suppl 2), S206-215.

Abstract

Objective: To assess the impact of different health warning labels (HWL).

Material and Methods: Data from the International Tobacco Control Survey (ITC Survey) were analyzed from adult smokers in Brazil, Uruguay and Mexico, each of which used a different HWL strategy (pictures of human suffering and diseased organs; abstract pictorial representations of risk; and text-only messages, respectively). Main outcomes were HWL salience and cognitive impact.

Results: HWLs in Uruguay (which was the only country with a HWL on the front of the package) had higher salience than either Brazilian or Mexican packs. People at higher levels of educational attainment in Mexico were more likely to read the text-only HWLs whereas education was unassociated with salience in Brazil or Uruguay. Brazilian HWLs had greater cognitive impacts than HWLs in either Uruguay or Mexico. HWLs in Uruguay generated lower cognitive impacts than the text-only HWLs in Mexico. In Brazil, cognitive impacts were strongest among smokers with low educational attainment.

Conclusions: This study suggests that HWLs have the most impact when they are prominent (i.e., front and back of the package) and include emotionally engaging imagery that illustrates negative bodily impacts or human suffering due to smoking.

Abstract

The attitudes of smokers to tobacco control interventions is highly topical in New Zealand given the current inquiry by the Maori Affairs Select Committee into tobacco issues. Presenters to this Committee have raised the need for a tobacco endgame strategy (e.g.), and this idea has currency among Maori leadership, nongovernmental organisations, and amongst other researchers. In the 2006 Census 30.3% of adult Pacific peoples in New Zealand reported being smokers, compared to 19.4% of the European population.7 Tobacco use is a substantial burden on the health of Pacific peoples and is likely to be contributing significantly to the health inequalities between Pacific peoples and other New Zealanders (e.g. see the emerging differences in lung cancer mortality rates). Harm to health and expenditure on tobacco is also likely to be holding back the social and economic development of Pacific communities. Pacific peoples support improved tobacco control, and in a 2008 national survey (smokers and nonsmokers) there was much stronger support than average for tobacco regulation. This high level of support contrasts somewhat to that of Pacific policymakers—at least for extending smokefree regulations. Here we describe the results of another national survey that considered attitudes of Pacific smokers to a range of tobacco control policy options.

Abstract

Considerations around advancing tobacco control are particularly relevant to New Zealand at present, given the current Inquiry by the Māori Affairs Select Committee into the tobacco industry. While there are good arguments for a rapid endgame solution to the tobacco epidemic (involving a phase out of tobacco sales over 10 years) other supplementary measures should also be considered to help lower demand for tobacco – regardless of the adoption of endgame policies. There is international evidence, and evidence from New Zealand, that point of-sale (PoS) tobacco displays encourage tobacco uptake among children and undermine cessation among smokers wishing to quit and who have recently quit. Other New Zealand research has identified that the arguments for tobacco displays are contradictory and flawed and that there is poor compliance with the current (albeit relatively weak) law on tobacco displays. New Zealand data indicate majority public support for additional marketing restrictions on tobacco. Around half (53.4%) of respondents to a national survey agreed that “tobacco companies should not be allowed to promote cigarettes by having different brand names and packaging” (22.6% disagreed), and 65.6% wanted fewer tobacco retailers. We have previously reported that a majority (62.5%) of Māori smokers support a ban on PoS tobacco displays. Here we draw on additional survey data to examine this issue further.

Abstract

Background: The internet is an ideal forum for tobacco marketing, as it is largely unregulated and there is no global governing body for controlling content. Nevertheless, tobacco companies deny advertising on the internet.

Objective: To assess the extent and nature of English language videos available on the Web 2.0 domain 'YouTube' that contain tobacco brand images or words.

Methods: The authors conducted a YouTube search using five leading non-Chinese cigarette brands worldwide. The themes and content of up to 40 of the most viewed videos returned for each search were analysed: a total of 163 videos.

Results: A majority of the 163 tobacco brand-related videos analysed (71.2%, 95% CI 63.9 to 77.7) had pro-tobacco content, versus a small minority (3.7%) having anti-tobacco content (95% CI 1.4 to 7.8). Most of these videos contained tobacco brand content (70.6%), the brand name in the title (71.2%) or smoking imagery content (50.9%). One pro-smoking music video had been viewed over 2 million times. The four most prominent themes of the videos were celebrity/movies, sports, music and 'archive', the first three of which represent themes of interest to a youth audience.

Conclusions: Pro-tobacco videos have a significant presence on YouTube, consistent with indirect marketing activity by tobacco companies or their proxies. Since content may be removed from YouTube if it is found to breach copyright or if it contains offensive material, there is scope for the public and health organisations to request the removal of pro-tobacco content containing copyright or offensive material. Governments should also consider implementing Framework Convention on Tobacco Control requirements on the internet, to further reduce such pro-tobacco content.

Abstract

In 2008 the law required tobacco packaging in New Zealand to include pictorial health warnings (PHWs) and the national Quitline number. Previously, text-only health warnings provided a telephone number, but did not explicitly link this to the “Quitline”. Research indicated that New Zealand smokers became more aware of the Quitline number on packs since PHWs were introduced, and there was an immediate increase in the proportion of new callers who registered with the Quitline following the introduction of PHWs. We investigated whether Quitline callers’ use of packaging to source the Quitline number continued beyond the initial introduction of PHWs.

Methods: The national free-phone Quitline service in New Zealand routinely collects data on where new callers sourced the Quitline number (i.e., a standardised question asked of all new callers). The Quitline service provided us with data on the proportion of new callers who reported obtaining the Quitline number from cigarettes packaging before and after the introduction of PHWs (i.e. for the three-year period March 2007 to February 2010). These data were compared to the proportion of callers who cited television advertising as the source of this number (which was the major source at the start of the study period). We reviewed monthly “target audience rating points” (TARPs) data on the reach and frequency of television advertising for smoking cessation advertisements (most of them showed the Quitline number).

Results and Discussion: During the 12-month pre-PHWs period (March 2007 to February 2008), 7.5% and 34.9% of new callers (out of n=19,558 total callers), cited tobacco packaging and television advertising respectively as their source for the Quitline number (Figure 1). However, in the first full year of the new PHWs (March 2008 to February 2009), the proportions reporting tobacco packaging as the source increased to 26.4% and television advertising declined to 27.1% (out of n=20,152 total callers). The same pattern was still evident in the subsequent 12-month period at 22.9% and 23.3% respectively (n=18,309 for the period March 2009 to February 2010).

Abstract

Increasing the price of tobacco products through tobacco taxation is one of the most effective tobacco control interventions. An additional benefit is that a “dedicated tobacco tax” (where some or all of the revenue raised is earmarked for specific spending or programmes) can generate revenue for funding other tobacco control and health programmes. Should dedicated tobacco taxes be introduced, it will be useful for decision makers to know whether there is support from all sociodemographic categories of smokers. Accordingly, we aimed to examine smoker support for tobacco taxes by an individual level measure of deprivation.

Abstract

To evaluate relevant issues around smoker knowledge and misperceptions about tobacco smoking, a cohort group of 1376 New Zealand smoking adults aged >18 years and 607 Maori respondents were surveyed between March 2007 and February 2008. Specific questions relevant to possible misinformation included perceptions related to light/mild cigarettes/tobacco, to menthols, and to RYO tobacco. Overall results indicated that sizeable minorities of both Maori and European/other smokers had various misperceptions about tobacco products. Regarding light and mild cigarettes, nearly half (48%) of Maori smokers have at least one of three misperceptions which suggest (erroneously) that these cigarettes have health benefits compared to “regular” cigarettes. Also, New Zealand smokers have misperceptions about mentholated cigarettes (“menthols”) being less harmful relative to “non-mentholated” cigarettes. This misperception was significantly more common (13% vs 7%) among Maori smokers. In addition, a minority (up to 10%) of Maori smokers also have specific misperceptions about the adverse health effects of second-hand smoke. Around a fifth of Maori and European/other smokers gave health reasons for smoking RYO cigarettes. Smokers also have high levels of knowledge deficits and misperceptions around smokeless tobacco products. Finally, a substantial group of smokers agree or strongly agree that “tobacco companies have done everything they can to reduce the harm caused by smoking,” and Maori smokers were significantly more likely to have this view (24%) compared to 18% of European/other. In conclusion, these data on smoker misperceptions are likely to be associated with tobacco industry messages on packaging.

Abstract

Aim: In September 2008, the New Zealand (NZ) Commerce Commission issued a warning to the major tobacco companies to remove “light” and “mild” descriptors from cigarette packaging. Despite published evidence that suggested tobacco companies had started colour-coding their packs in anticipation of the Commission's decision, the investigation did not consider more general misleading packaging. This study explored changes in tobacco packaging that had been introduced to the New Zealand market, by surveying descriptors used on cigarette packs after the Commerce Commission's warning.

Method: A convenience sample of discarded cigarette packs were collected in four cities and six towns/rural areas between November 2008 and January 2009. The majority of packs (93%) were collected in the capital city (Wellington). Information on the descriptors and pack colours was analysed.

Results: Four percent of the 1208 packs collected still included the terms “light” and “mild”. Almost half the packs (42%) used a colour word (e.g. red, blue, gold) as a descriptor to indicate mildness or strength. A further 18% used other words that suggested mildness/strength (e.g. “subtle”, “mellow”). A quarter of packs used a descriptor that did not connote either mildness or strength; however, the majority of these packs still appeared to be colour-coded.

Conclusion: Although the words “light” and “mild” have been largely removed from tobacco packaging in the New Zealand market, these words have been replaced with associated colours or other words that may continue to communicate “reduced harm” messages to consumers. Further research to test how smokers interpret the new words and colours, and how these influence their behaviour, is desirable. However, government-mandated generic (plain) packaging would remove the opportunity to communicate misleading claims and so would afford the highest level of consumer protection.

Abstract

Objective: To explore the determinants of smoking behaviour in recreational venues and to provide scientific bases for establishing smoke-free measures applying to these locations.

Methods: The International Tobacco Control (ITC) China Survey—a face-to-face cross-sectional survey of representative adult smokers from six cities (Shenyang, Beijing, Shanghai, Guangzhou, Changsha and Yinchuan) was conducted between April and August 2006. A total of 4815 smokers were selected using multistage sampling methods, and final analyses were conducted on 2875 smokers who reported patronising recreational venues at least once in the last six months. Multivariate logistic regression models were used to identify factors influencing the smoking behaviour within recreational settings.

Outcome Measure: Whether a smoker reported smoking in recreational venues during the last 6 months.

Results: 84% of subjects reported smoking in recreational venues. 32.0% of patrons reported partial The following factors were significant predicators of smoking in recreational venues: absence of bans on smoking, support for non-bans, being aged 18–24 years, positive smoking-related attitudes, low number of health effects reported and not living in Beijing.

Conclusions: The findings point to the importance of informing Chinese smokers about the active smoking and passive smoking harmfulness in both building support for smoke-free laws and in reducing smokers’ desire to smoke within recreational venues. They also point to the importance of good enforcement of smoke-free laws when implemented. Such strategies could also serve to de-normalise smoking in China.

Abstract

In 2008 we published the overall support by New Zealand smokers for smokefree cars containing preschool children (96%).1 To provide further detail on the support by different groups, we examined the support by age-groups, gender, ethnicity, level of socioeconomic deprivation, and level of financial stress. The data came from the wave 1 of the New Zealand arm of the International Tobacco Control Policy Evaluation Survey (NZ ITC Project). This wave involved surveying a national sample of 1376 New Zealand adult (18+ years) smokers in 2007–2008. We asked: Do you think smoking should be allowed in cars with preschool children in them? Further detail on the survey methods is available elsewhere.2 We found that smokers in all age-groups, both men and women, those in the four ethnic groups considered, and those in all small area deprivation quintiles, disagreed with the statement at a level of 92%+ (Table 1). Of those smokers who reported suffering from two different types of smoking-related financial stress (those unable to pay any important bills on time due to a shortage of money, and those not spending on household essentials due to spending on smoking) over 92% also disagreed (see Table 1). The key finding is that New Zealand smokers from different socio-demographic groups appear to give very high support for not allowing smoking in cars carrying preschool children. These data are further supported by results from a 2008 national survey of the New Zealand public, which found 91% (82% for smokers) agreeing with the statement ‘that smoking should not be allowed in cars with children under the age of 14 in them’.3 These results indicate that there is strong support across a very wide range of smokers (and from the public) for active government intervention to protect New Zealand children from tobacco smoke pollution in cars. We need to consider why New Zealand is lagging behind 11 states and provinces in Australia, Canada, and the USA, which have all passed laws to protect their children from smoking in cars.4 While further social marketing campaigns on this theme are desirable, we suggest that smokefree car legislation is an appropriate use of the law, and would provide a strong signal on the priority of child protection from tobacco smoke. If the New Zealand Parliament is going to consider banning cell phone use while car driving, they could consider smokefree cars at the same time.

Abstract

Objective: To test whether differences of history and strength in tobacco control policies will influence social norms, which, in turn, will influence quit intentions, by influencing smokers’ regret and rationalization.

Design: The data were from the International Tobacco Control (ITC) Policy Evaluation Southeast Asia Survey, a cohort survey of representative samples of adult smokers in Thailand (N _2,000) and Malaysia (N _ 2,006). The survey used a stratified multistage sampling design.

Main Outcome Measures: Measures included regret, rationalization, social norms, and quit intention.

Results: Thai smokers were more likely to have quit intentions than Malaysian smokers. This difference in quit intentions was, in part, explained by the country differences in social norms, regret, and rationalization. Reflecting Thailand’s history of stronger tobacco control policies, Thai smokers, compared with Malaysian smokers, perceived more negative social norms toward smoking, were more likely to regret, and less likely to rationalize smoking. Mediational analyses revealed that these differences in social norms, accounted, in part, for the country-quit intention relation and that regret and rationalization accounted, in part, for the social norm-quit intention relation.

Conclusion: The results suggest that social norms toward smoking, which are shaped by tobacco control policies, and smokers’ regret and rationalization influence quit intentions.

Abstract

Objective: To examine the association of financial stress with interest in quitting smoking, making a quit attempt and quit success.

Design and participants: The analysis used data from 4984 smokers who participated in waves 4 and 5 (2005–07) of the International Tobacco Control (ITC) Four Country Survey, a prospective study of a cohort of smokers in the United States, Canada, the United Kingdom and Australia.

Measurement: The outcomes were interest in quitting at wave 4, making a quit attempt and quit success at wave 5. The main predictor was financial stress at wave 4: ‘. . . because of a shortage of money, were you unable to pay any important bills on time, such as electricity, telephone or rent bills?’. Additional socio-demographic and smoking-related covariates were also examined.

Findings: Smokers with financial stress were more likely than others to have an interest in quitting at baseline [odds ratio (OR): 1.63; 95% confidence interval (CI): 1.22–2.19], but were less likely to have made a quit attempt at follow-up (OR: 0.74; 95% CI: 0.57–0.96). Among those who made a quit attempt, financial stress was associated with a lower probability of abstinence at follow-up (OR: 0.53; 95% CI: 0.33–0.87).

Conclusions: Cessation treatment efforts should consider assessing routinely the financial stress of their clients and providing additional counseling and resources for smokers who experience financial stress. Social policies that provide a safety net for people who might otherwise face severe financial problems, such as not being able to pay for rent or food, may have a favorable impact on cessation rates.

Abstract

Objective: To characterize smoking beliefs among Thai and Malaysian youth and to examine associations with gender, antismoking media exposure, and smoking status.

Methods: Nationally representative samples of youth completed self-administered questionnaires.

Results: A substantial proportion of youth reported positive beliefs about smoking. Those reporting positive beliefs were more likely to be susceptible to smoking. Youth who noticed antismoking media were less likely to report positive beliefs about smoking.

Conclusions: As in Western countries, beliefs about smoking held by youth in Southeast Asia are associated with smoking status. Antismoking media may be an important means of targeting beliefs about smoking among youth.

Attitudes and beliefs about secondhand smoke and smoke-free policies in four countries: Findings from the International Tobacco Control Four Country Survey. Nicotine & Tobacco Research, 11(6), 642-649.

Abstract

Introduction: This paper describes the varying levels of smoking policies in nationally representative samples of smokers in four countries and examines how these policies are associated with changes in attitudes and beliefs about secondhand smoke over time.

Methods: We report data on 5,788 respondents to Wave 1 of the International Tobacco Control Four Country Survey who were employed at the time of the survey. A cohort of these respondents was followed up with two additional survey waves approximately 12 months apart. Respondents ’ attitudes and beliefs about secondhand smoke as well as self-reported policies in their workplace and in bars and restaurants in their community were assessed at all waves.

Results: The level of comprehensive smoke-free policies in workplaces, restaurants, and bars increased over the study period for all countries combined and was highest in Canada (30%) and lowest in the United Kingdom (0%) in 2004. In both crosssectional and longitudinal analyses, stronger secondhand smoke policies were associated with more favorable attitudes and support for comprehensive regulations. The associations were the strongest for smokers who reported comprehensive policies in restaurants, bars, and their workplace for all three survey waves.

Discussion: Comprehensive smoke-free policies are increasing over time, and stronger policies and the public education opportunities surrounding their passage are associated with more favorable attitudes toward secondhand smoke regulations. The implication for policy makers is that, although the initial debate over smoke-free policies may be tumultuous, once people understand the rationale for implementing smoke-free policies and experience their benefits, public support increases even among smokers, and compliance with smoke-free regulations increases over time.

Abstract

Objective: To collect the information on nicotine dependence of Chinese adult smokers and understand the related factors of high nicotine dependence in adult smokers.

Methods: Used 4800 adult smokers, interviewed in Beijing, Shenyang, Shanghai, Changsha, Guangzhou and Yinchuan 1,800 smokers in each city were selected with multiple stages sampling method.

Results: The level of HIS was 215 ±117 in adult smokers in China, 215 ±117 for male and 119 ±117 for female, which were lower than that of smokers in developed countries1 The result of logistic regressions for predicting the probability of high nicotine dependence showed that gender, age, education, years after becoming a regular smoker, health consciousness and p rice per pack of last purchase could enter the equation1 Male (OR = 21352) and lower education had significant associations with high nicotine dependence. The lower education the smokers had, the higher nicotine dependence they were (the high education as contrasted, the OR of the medium education was 11417; the OR of low education was 11853) People who had smoked more than 10 years had high nicotine dependence (OR = 41519) People who regarded smoking was neither good nor bad for their own health (OR = 11345) , regarded smoking was good for their own health (OR = 21419) and purchased below 4 yuan per pack (OR = 11635) had high nicotine dependence.

Conclusion: Compared with developed countries, the HSI level was lower in China Male, higher age, lower education, smoking more than 10 years, failing to understand smoking damage, and purchasing cheap cigarettes were associated with high nicotine dependence.

Abstract

Background: Many smokers believe that "light" cigarettes are less harmful than regular cigarettes, which is at variance with the scientific evidence. The Framework Convention on Tobacco Control (FCTC) aims to address this problem in Article 11 which deals with misleading labelling of tobacco products. In this study we aimed to determine smokers' use and beliefs concerning "light" and "mild" cigarettes ("lights"), including in relation to ethnicity, deprivation and other socio-demographic characteristics.

Methods: The New Zealand (NZ) arm of the International Tobacco Control Policy Evaluation Survey (ITC Project) uses as its sampling frame the NZ Health Survey. This is a national sample with boosted sampling of Maori, Pacific peoples and Asians. From this sample we surveyed adult smokers (n = 1376) about use and beliefs relating to "light" cigarettes. We assessed the associations with smoking "lights" after adjusting for socio-demographic variables, and smoking-related behaviours and beliefs.

Results: Many smokers of "lights" believed that smoking "lights" made it easier to quit smoking (25%), that "lights" are less harmful (42%), and that smokers of "lights" take in less tar (43%). Overall most "lights" smokers (60%) had at least one of these three beliefs, a proportion significantly higher than for smokers of "regular" cigarettes at 45% (adjusted odds ratio (aOR) = 1.96, 95% CI = 1.29 – 2.96). While "lights" smokers had significantly lower tobacco consumption and were more aware of smoking harms, they were no more likely to be intending to quit or have made a previous quit attempt. By ethnicity, both Maori and Pacific people were less likely to smoke "lights" than Europeans (aOR = 0.53, 95% CI = 0.35 – 0.80 and aOR = 0.14, 95% CI = 0.05 – 0.40 respectively). In contrast there was no significant difference by level of deprivation. Roll-your-own (RYO) tobacco smokers were less likely to smoke "light" forms of RYO tobacco while both older and women smokers were more likely to smoke "lights".

Conclusion: Most "lights" smokers have one or more misperceptions about the product they use, and were no more likely to intend to quit or to have made a quit attempt. In response to such misperceptions, governments could act further to eliminate all misleading tobacco marketing. Ideally, they could not only adopt FCTC requirements, but go further by requiring plain packaging for all tobacco products.

Abstract

Background: China currently does not have comprehensive laws or regulations on tobacco advertising and promotion, although it ratified the World Health Organization (WHO) Framework Convention on Tobacco Control (FCTC) in October 2005 and promised to ban all tobacco advertising by January 2011. Much effort is needed to monitor the current situation of tobacco advertising and promotion in China.

Objective: This study aims to examine levels of awareness of tobacco advertising and promotion among smokers in China as compared to other countries with different levels of restrictions.

Methods: One developing country (Thailand) and two developed countries (Australia and the USA) were selected for comparison. All four countries are part of the International Tobacco Control (ITC) Policy Evaluation Survey project. Between 2005 and 2006, parallel ITC surveys were conducted among adult smokers (at least smoked weekly) in China (n=4763), Thailand (n=2000), Australia (n=1767) and the USA (n=1780). Unprompted and prompted recall of noticing tobacco advertising and promotion were measured.

Results: Chinese respondents reported noticing tobacco advertisements in a range of channels and venues, with highest exposure levels on television (34.5%), billboards (33.4%) and in stores (29.2%). A quarter of respondents noticed tobacco sponsorships, and a high level of awareness of promotion was reported. Cross-country comparison reveals that overall reported awareness was significantly higher in China than in Thailand (particularly) and Australia, but lower than in the USA.

Conclusions: There is a big gap between China and the better-performing countries such as Thailand and Australia regarding tobacco promotion restrictions. China needs to do more, including enhanced policy and more robust enforcement.

Abstract

Introduction: The longitudinal ITC Scotland/U.K. survey was used to investigate adult smokers ’ support for smoke-free legislation and whether this support was associated with higher quit intentions at follow-up, either directly or indirectly, via the mediation of perceived social unacceptability of smoking.

Methods: Structural equation modeling was employed to compare differences between the two samples (507 adult smokers from Scotland and 507 from the rest of the United Kingdom) across two waves (February/March 2006 and March 2007). During these two waves, a smoking ban was introduced in Scotland but not the rest of the United Kingdom.

Results: For smokers in both samples, support for smoke-free legislation at baseline significantly heightened perceived unacceptability of smoking, although perceptions of unacceptability were somewhat stronger in Scotland than the rest of the United Kingdom post ban. Unlike the rest of the United Kingdom, support for a ban at baseline among smokers in Scotland was associated with higher quit intentions at follow-up. For both samples, quit intentions were significantly associated with heightened perceived unacceptability at follow-up. The overall variance explained in quit intentions was greater in Scotland than in the rest of the United Kingdom but not significantly so.

Discussion: Support for smoke-free legislation at baseline significantly increased support at follow-up for both samples. However, this did not independently increase quit intentions among smokers from both Scotland and the rest of the United Kingdom. The findings suggest that normative influences are one of the mechanisms through which comprehensive smokefree legislation influences quit intentions.

Abstract

Introduction: This paper is concerned with the effects of cigarette pack warning labels on quitting intentions. We examined whether different responses among smokers toward cigarette pack warning labels could predict quit intentions and self-efficacy in quitting. Variables studied were “noticing warning labels during last month,” “reading or looking closely at warning labels,” “avoiding looking at labels during last month,” “thinking about health risks of smoking because of the warning labels, “more likely to quit because of the warning labels,” and “stopping from having a cigarette when about to smoke one because of the labels.”

Methods: A total of 2,006 adult smokers in Malaysia were surveyed in face-to-face interviews using a standardized questionnaire. Of those, 1,919 male smokers were included in the analyses.

Results: The responses “more likely to quit because of the warning labels” and “stopped from having a cigarette when about to smoke one ” significantly predicted all stages of change and self-efficacy, independent of the other measures. In addition, thinking about the health risks and reading the warnings more often added extra predictive capacity but only in the early stages of contemplating change.

Discussion: Less intense processing of the information may be important in initiating thoughts, but cognitions about quitting and foregoing cigarettes are the key mechanisms by which warnings stimulate quitting intentions and help smokers feel capable of succeeding. Malaysian smokers appear to respond to warnings in ways comparable with those from developed countries.

Abstract

There is little doubt that nicotine addiction sustains tobacco use in most people and that individual variation in response to tobacco has a strong biological basis. However, the great diversity in tobacco use behaviors observed between countries and within countries over time suggests that biology alone cannot fully explain these variations. This review examines the role of the social environment in understanding tobacco use behaviors and efforts to curb tobacco use at the population level. We conclude that the social environment plays a critical role in determining how innate biological factors involved in nicotine dependency actually get expressed at the population level. Tobacco use as reflected in population trends is seen as the product of the interaction of agent, host, and environmental factors. Government policies are seen as an important modifiable environmental influence that can alter how tobacco products are designed and marketed (agent factors) and how consumers perceive the risks and benefits of smoking (host factors). Evidence suggests that synergy is gained when tobacco control interventions directed at agent, host, and environmental factors are implemented together.
