Methods: Analysis of internal tobacco industry documents and public advertising collections.
Results: Tobacco industry market research attempted to identify the psychosocial needs of different groups of women, and cigarette advertising campaigns for brands that women smoke explicitly aimed to position cigarettes as capable of satisfying these needs. Such positioning can be accomplished with advertising that downplays or excludes smoking imagery. As women's needs change with age and over time, advertisements were developed to reflect the needs encountered at different stages in women's lives. Cigarette brands for younger women stressed female camaraderie, self confidence, freedom, and independence; cigarette brands for older women addressed needs for pleasure, relaxation, social acceptability, and escape from daily stresses.
Conclusions: Psychosocial needs satisfaction can be communicated without reference to cigarettes or smoking. This may explain why partial advertising bans are ineffective and comprehensive bans on all forms of tobacco marketing are effective. Counter-advertising should attempt to expose and undermine the needs satisfaction messages of cigarette advertising campaigns directed at women.
相似文献Design: Data are presented from the 2003 Canadian Tobacco Use Monitoring Survey, a national survey of smoking behaviour (n = 10 559, response rate 89%).
Main outcome measures: Measures of smoking behaviour, smoking initiation, susceptibility to smoking, and occupational status.
Results: A total of 1.4 million or 28% of young adults in Canada currently smoke, the highest proportion among all age groups. The prevalence of daily smoking rose from 8% among youth to 22% among young adults, and approximately one fifth of smokers tried their first cigarette after the age of 18 years. Smoking behaviour among young adults was also distinct from older smokers: young adults were more likely to be occasional smokers and reported lower daily consumption. Finally, smoking prevalence and cessation rates varied substantially within subgroups of young adults, as characterised by occupational setting.
Conclusions: Dramatic increases in the proportion and intensity of smoking occurs after the age of 18 years. Smoking behaviour among young adults is distinct from both youth and older adults, and warrants immediate attention from the public health community.
相似文献Data: The Current Population Survey's 1992/93 and 1998/99 tobacco use supplement surveys are the primary data source, supplemented with information on state level tobacco control policies.
Methods: The national and state rate of bans are estimated, and changes over the course of the 1990s and their relation to smoking rates and tobacco control policies are examined.
Results: The prevalence of work and home bans has increased considerably between 1992/93 and 1998/99. By 1999, over 65% of the population age 15 and above work in places with smoking bans, and over 60% live in homes with bans. We found that states with lower than average ban rates in 1993 tended to have had larger increases in ban rates between 1993 and 1999. We also found that home and work bans became more prevalent in states with initially low smoking rates, and that the growth in home bans coincided with a declining prevalence of smoking. States with higher levels of bans by 1999 also tended to have higher cigarette taxes, stricter clean air laws, and media/comprehensive campaigns in place.
Conclusions: The results indicate that lower smoking rates are associated with higher rates of work and home bans, although substantial progress has also been made by those states with initially low rates of bans. While further work is needed to establish the direction of causality, it would appear that reductions in smoking rates, either through stronger tobacco control policies or otherwise, may reduce exposure to tobacco smoke not only by reducing the number of smokers, but also through increasing the number of firms and homes with smoking restrictions.
相似文献Methods: Data from the 1992–93, 1995–96, and 1998–99 Tobacco Use Supplements to the national Current Population Survey (n > 175 000 each period) were used to examine changes in norms regarding where smoking should "not be allowed at all" in both California and in the rest of the USA. Venues queried were restaurants, hospitals, work areas, bars, indoor sports venues, and indoor shopping malls.
Results: There were substantial increases in the percentages of the adult population (18+ years) stating that smoking should not be allowed in the venues queried in California by 1998–99 compared to 1992–93; only modest increases were observed in the rest of the USA. In fact, for most venues, the percentages for the rest of the USA were lower in 1998–99 than in California in 1992–93. Further, the percentage increase over this period in respondents stating that smoking should not be allowed in four or more of the six venues was 30% in California and 23% in the rest of the USA. The most dramatic percentage increase in California occurred among current smokers (93%).
Conclusions: A strong, comprehensive tobacco control programme such as California's can influence population norms, including those of smokers, with respect to where smoking should not be allowed.
相似文献Outcome measures: Three outcome measures were frequency of smoking incidents, traits of characters who smoke, and consequences of tobacco use.
Results: 6% of characters smoked in 453 incidents, including 3% of children. In 92% of incidences, smoking had no consequences. The most frequent consequence was a verbal reprimand. Although tobacco is a leading cause of preventable deaths globally, only 0.4% of tobacco incidences resulted in death. No deaths were caused by disease. Characters who smoked tended to be major characters playing leadership roles. They tended to be from privileged elites: male, white, and mature.
Conclusions: Films portray characters that smoke as leaders from privileged elites, making smoking more attractive to audience members. Because 99.6% of characters suffer no life threatening consequences from smoking on screen, smokers seem invincible, belying tobacco's role as a leading cause of preventable deaths.
相似文献Methods: Systematic search of internal tobacco industry documents available on the internet and at the British American Tobacco Guildford Depository.
Results: Despite legal loss, the litigation contributed to subsequent tobacco control legislation in Finland. The proceedings revealed that the industry had concealed the health hazards of its products and, despite indisputable evidence, continued to deny them. The positions taken by the industry rocked its reliability as a social actor and thus weakened its chances of influencing tobacco policy. Despite fierce opposition from the tobacco industry, tobacco products were included in the product liability legislation, tobacco was entered on the Finnish list of carcinogens, and an extensive Tobacco Act was passed in Parliament.
Conclusions: Tobacco litigation might not stand alone as a tool for public health policymaking but it may well stimulate national debate over the role of smoking in society and influence the policy agenda.
相似文献Design: Three separate analytic approaches were conducted on baseline self report student survey data from a larger study to test the relation between school level perceived peer tobacco use and individual current smoking status.
Participants: A representative sample of 5399 sixth through eighth grade students in 14 midwestern middle schools completed the survey. All enrolled sixth through eighth grade students were eligible to participate in the survey. The student participation rate was 91.4% for the entire sample, and did not differ significantly between the schools (range 82–100%).
Main outcome measure: Thirty day cigarette smoking prevalence.
Results: A level 2 only model based on aggregated individual responses indicated that students in schools with higher average reported peer tobacco use were more likely to be current smokers than students in schools with lower average peer tobacco use. Using a level 1 only model based on individual responses indicated that the effect of school level perceived peer tobacco use on current smoking was significant when individual perceived peer tobacco use was excluded from the model but was non-significant when individual perceived peer tobacco use was added to the model. A multilevel model also indicated that the effect of school level perceived peer tobacco use on current smoking was not significant when individual perceived peer tobacco use was added to the model.
Conclusion: The analytic approach used to examine contextual effects using individuals' reports of peer tobacco use norms that were aggregated to obtain a context measure of the school norms may produce statistical artefacts that distort the association of the school context in general, and peer tobacco use norms in particular, with increased risk for current smoking beyond the risk associated with individual factors.
相似文献Objectives: To evaluate whether Brown & Williamson knew of the compensatability of Barclay during the design process and before it was released; to evaluate initial responses of competing tobacco companies to Barclay, before complaints were made to the Federal Trade Commission in 1981.
Methods: Internet databases of industry documents (Tobacco Documents Online, Legacy Tobacco Documents Library, Brown & Williamson Litigation discovery website, Guildford and major company websites) were searched using key words, key dates, and targeted searches. Documents related specifically to the development, evaluation and release of the Barclay cigarette and related to the responses by competing tobacco companies were examined.
Results: Documents indicate the manufacturer was aware of Barclay design problems and was planning, before release, to respond to criticism. Competing companies quickly detected the filter groove stratagem and considered developing their own similar filter, but eventually backed off.
Conclusion: The design problems with Barclay were readily understood by cigarette manufacturers, including the maker of Barclay, before official governmental evaluations occurred. Testing involving measured exposures to human smokers may in the end be crucial to identifying problems with novel cigarette designs.
相似文献Methods: Analysis of internal company documents.
Findings: Between 1982 and 1987 transnational tobacco companies influenced the Japanese government through the US Trade Representative to open distribution networks and eliminate advertising restrictions. US cigarette exports to Japan increased 10-fold between 1985 and 1996. Television advertising was central to opening the market by projecting a popular image (despite a small actual market share) to attract existing smokers, combined with hero-centred advertisements to attract new smokers. Philip Morris's campaigns featured Hollywood movie personalities popular with young men, including James Coburn, Pierce Brosnan, Roger Moore, and Charlie Sheen. Event sponsorships allowed television access despite restrictions. When reinstatement of television restrictions was threatened in the late 1980s, Philip Morris more than doubled its television advertising budget and increased sponsorship of televised events. By adopting voluntary advertising standards, transnational companies delayed a television advertising ban for over a decade.
Conclusions: Television image advertising was important to establish a market, and it has been enhanced using Hollywood personalities. Television advertising bans are essential measures to prevent industry penetration of new markets, and are less effective without concurrent limits on sponsorship and promotion. Comprehensive advertising restrictions, as included in the Framework Convention for Tobacco Control, are vital for countries where transnational tobacco companies have yet to penetrate the market.
相似文献Design: A web/mail survey conducted in October and November 2002, with a telephone survey of a sample of non-respondents.
Subjects: The 2833 US based registrants for the 2001 National Conference on Tobacco or Health.
Main outcome measures: Respondents' awareness of THR, perception of its importance, support for regulation, and perception of which THR products should be recommended to inveterate cigarette smokers.
Results: 70% of respondents were aware of THR but respondents had low recognition of specific products at the forefront of the debate, such as Swedish snuff. Half believe THR will reduce smoking cessation and cause nicotine experimentation by children; 63% anticipate unintended adverse side effects. More expect THR to have a negative than a positive impact on health. Large majorities support government regulation of THR and conventional tobacco products, but fewer than 30% expect legislation regulating either. Most would recommend nicotine patches (76%) and gum (70%) to inveterate smokers, but no other product was supported by a majority. Scientists are more supportive of THR than activists, while respondents focusing on national/international issues are more supportive than those concentrating on local/state issues.
Conclusions: Many members of the US tobacco control community are unaware of the THR "movement", while others possess only rudimentary familiarity with it. If and as THR achieves an increasingly prominent role on the tobacco-or-health scene, this community will have to become educated about THR, and be prepared to advocate for regulatory policies that will maximise the potential for positive outcomes. The potential for negative outcomes remains significant.

Results: Data are presented from 75 sites in 43 countries and the Gaza Strip/West Bank region. Current use of any tobacco product ranges from 62.8% to 3.3%, with high rates of oral tobacco use in certain regions. Current cigarette smoking ranges from 39.6% to less than 1%, with nearly 25% of students who smoke, having smoked their first cigarette before the age of 10 years. The majority of current smokers want to stop smoking and have already tried to quit, although very few students who currently smoke have ever attended a cessation programme. Exposure to advertising is high (75% of students had seen pro-tobacco ads), and exposure to environmental tobacco smoke (ETS) is very high in all countries. Only about half of the students reported that they had been taught in school about the dangers of smoking during the year preceding the survey.
Conclusions: Global youth tobacco use is already widespread throughout the world, but there is great variation among nations. Valid and reliable data on the extent of youth tobacco use, and correlates of use, are essential to plan and evaluate tobacco use prevention programmes. The GYTS has proven the feasibility of an inexpensive, standardised, worldwide surveillance system for youth tobacco use. The GYTS will be expanded to the majority of countries in the next few years, and can serve as a baseline for monitoring and evaluating global and national tobacco control efforts.
相似文献Design: Repeated annual cross sectional surveys.
Setting: Seventy five communities in Oregon.
Participants: A random sample of students in grades 8 and 11 (ages 13 and 17 years) and retail outlets in each participating community.
Main outcome measures: Thirty day and daily smoking prevalence.
Results: The rate of illegal merchant sales in the communities was related to the smoking rate for 11th graders in those communities, but not for 8th graders. For every 10% increase in illegal sales rates there was an estimated 0.8% increase in 11th grade 30 day smoking prevalence and a 0.4% increase in daily smoking. Communities with lower illegal merchant sales rates had expanded use of social sources and reduced use of commercial sources by 11th graders, with the opposite pattern seen in 8th graders.
Conclusions: There appears to be a relatively small positive linear relation between the community rate of sales to minors and 11th grade youth smoking prevalence in those communities. Youth adjust their tobacco sources depending on the level of commercial availability.
相似文献Design: Cross sectional, nationally representative population based household survey.
Subjects: 315 598 individuals 15 years or older from 91 196 households were sampled in National Family Health Survey-2 (1998–99). Data on tobacco consumption were elicited from household informants.
Measures and methods: Prevalence of current smoking and current chewing of tobacco were used as outcome measures. Simple and two way cross tabulations and multivariate logistic regression analysis were the main analytical methods.
Results: Thirty per cent of the population 15 years or older—47% men and 14% of women—either smoked or chewed tobacco, which translates to almost 195 million people—154 million men and 41million women in India. However, the prevalence may be underestimated by almost 11% and 1.5% for chewing tobacco among men and women, respectively, and by 5% and 0.5% for smoking among men and women, respectively, because of use of household informants. Tobacco consumption was significantly higher in poor, less educated, scheduled castes and scheduled tribe populations. The prevalence of tobacco consumption increased up to the age of 50 years and then levelled or declined. The prevalence of smoking and chewing also varied widely between different states and had a strong association with individual's sociocultural characteristics.
Conclusion: The findings of the study highlight that an agenda to improve health outcomes among the poor in India must include effective interventions to control tobacco use. Failure to do so would most likely result in doubling the burden of diseases—both communicable and non-communicable—among India's teeming poor. There is a need for periodical surveys using more consistent definitions of tobacco use and eliciting information on different types of tobacco consumed. The study also suggests a need to adjust the prevalence estimates based on household informants
相似文献Objective: To assess smokers' and ex-smokers' perceptions of PREPs and the impact of PREP claims on interest in quitting (among smokers) or in resuming smoking (ex-smokers).
Design: A random-digit-dialled survey of US smokers and ex-smokers. We used Eclipse, a modified PREP cigarette, as an exemplar PREP. During the survey, the interviewer read risk reduction claims made for Eclipse by its manufacturer, assessing smokers' interest in quitting before and after the exposure.
Participants: 1000 current cigarette smokers and 499 ex-smokers (300 quit within the last two years), over 18 years old.
Main outcome measures: Perception of risk reduction from Eclipse; interest in using Eclipse; smokers' interest in quitting was assessed using a stage of change approach (pre- and post-exposure to claims).
Results: 91% of smokers thought Eclipse was safer than regular cigarettes. 24% believed Eclipse was completely safe. 57.4% of smokers were interested in using Eclipse; interest was greatest among smokers who were contemplating quitting. Exposure to Eclipse's claims was followed by reduced interest in quitting. Among all ex-smokers, interest in Eclipse was 6.2%, but interest was 15.2% among young adults (18–25 years) who had stopped smoking within two years.
Conclusions: There is substantial risk that smokers will overinterpret reduced risk claims made for modified tobacco products. PREPs appeal to smokers who are contemplating quitting and exposure to reduced risk product claims appears to reduce smokers' readiness to quit. PREPs also appealed to young adults who had recently stopped smoking. Thus, reduced risk tobacco product claims can undermine adult cessation and youth prevention, possibly resulting in increased harm even if the products are less toxic.
相似文献Design: Analysis of internet purchasing in data from a population based telephone survey of New Jersey households. Logistic regression was used to determine factors associated with internet cigarette purchasing, adjusting for year, demographic, and smoking behaviour variables.
Participants: 3447 current cigarette smokers pooled from three cross sectional surveys conducted in 2000, 2001, and 2002.
Main outcome measures: Ever purchasing tobacco and usually buying cigarettes via the internet.
Results: Among all current cigarette smokers, ever having purchased tobacco via the internet increased from 1.1% in 2000 to 6.7% in 2002 and usually buying cigarettes via the internet increased from 0.8% in 2000 to 3.1% in 2002. Among current cigarette smokers with internet access, ever having purchased tobacco via the internet was higher among those who reported smoking 31 or more cigarettes per day (adjusted odds ratio (OR) 3.9, 95% confidence interval (CI) 1.5 to 10.2) and those without a past year quit attempt (adjusted OR 1.8, 95% CI 1.1 to 3.0). Usually purchasing cigarettes via the internet was higher among those aged 45–64 years (adjusted OR 4.4, 95% CI 1.1 to 17.1) and who reported having their first cigarette 30 minutes after waking (adjusted OR 3.3, 95% CI 1.2 to 9.2).
Conclusions: Although higher prices are known to reduce the demand for cigarettes, internet cigarette purchasing is likely to weaken this effect, particularly among heavy, more dependent smokers who are less interested in quitting.
相似文献Method: Surveys were distributed by athletic trainers to major and minor league professional baseball players during spring training session in the six years from 1998 to 2003. The surveys were anonymous and identified only by team, level of league, and other self reported demographic data.
Results: ST use among professional baseball players remains much higher than among young males in the general population, and use is most prevalent among white non-Hispanic players. There was a significant decrease in ST use among minor league players from 1998 to 2003, with seven day self reported use declining from 31.7% in 1998 to 24.8% in 2003. No significant year to year changes were observed for major league players. Major league players' self reported past week use rates, estimated at 35.9% in 1998 and at 36% in 2003, were consistently higher than those of minor league players. Self reported prevalence of past month cigarette and cigar smoking was much lower than ST use for both major and minor league players.
Conclusions: Six years of survey data confirm a continuing high use of ST among professional baseball players. Results suggest that the effects of the broad spectrum ST control efforts launched over the past decade may have been stronger among minor than major league players. Stronger policy interventions at the major league level and multi-level efforts, including programmes to increase the use of effective quitting aids and assistance, at both levels of play are needed. Future research is needed to further clarify changes in ST practices among professional players and set policy intervention directions.
相似文献Design and participants: Data were from 9364 young adult (18–29 years) respondents to the cross sectional population based 2002 California Tobacco Survey. As background, we analysed social smoking (only smoke with other smokers), and enjoyment of smoking while drinking. Our main focus was on bar and club attendance, what was observed in bars and clubs, and how this might differ according to respondents' risk for future smoking.
Results: Social smokers comprised 30.0 (2.2)% of all current smokers, including experimenters. Nearly three quarters (74.5 (2.3)%) of current smokers/experimenters said they enjoyed smoking while drinking. About one third (33.8 (1.2)%) of all young adults said they attended bars and clubs at least sometimes; attendance was significantly higher among smokers and those at risk for future smoking. Close to 60% (57.9 (2.2)%) of bar and club attenders reported seeing cigarette advertising and promotions in these settings. Again, smokers and those at risk were more likely to report seeing such advertising and promotions in these settings.
Conclusions: About 20% of all young adults and about 30% of those at risk for future smoking (including current smokers) were exposed to tobacco advertising and promotions in bars and clubs. These California results may be conservative, but nonetheless indicate that the group potentially influenced is sizable.
相似文献Design: Analysis of documents held at the BAT archive in Guildford, UK.
Results: Considerable priority was attached to investing in the FSU. This led BAT to undertake a major organisational change and to intense competition to acquire assets. BAT used flawed economic arguments to persuade cash starved governments that its investment would reap economic rewards. It offered excise advice that disadvantaged governments while benefiting BAT, confused issues over pricing, and avoided competitive tendering. BAT targeted agriculture ministries, using its expertise in leaf production to differentiate itself from other potential investors. It subverted the principles of corporate social responsibility to promote itself as a business partner. BAT's task was made easier by the naivety of post-Soviet governments and by the international financial organisations' support for rapid economic reform. The latter permitted tobacco transnationals to penetrate markets before effective competitive tendering processes had been established, giving them the opportunity to minimise prices and establish monopolies.
Conclusions: Many of the arguments employed when penetrating post-Soviet markets were highly misleading but governments lacked expertise to realise this. There is a need to build tobacco control capacity in transition economies, within and outside government, to ensure that governments are better informed of the true economic and health impacts of tobacco. Rapid transition from socialist to market economies without establishing regulatory institutional structures may be dangerous when investing companies use business practices that fall short of international standards.
相似文献Design: Research was conducted through a web based search of internal tobacco industry documents made publicly available through litigation.
Main results: For approximately €1 000 000 Philip Morris (now Altria) became a co-initiator of Living Tomorrow 2, a tourist complex in Belgium that aims to demonstrate how we will be living in the future. In addition to promoting the company and its grocery products, Philip Morris is using the complex and its website to promote ventilation as a means of accommodating smokers and non-smokers in the indoor environment. Particular emphasis was placed on the bar and restaurant areas. Despite the rationale for its involvement, Philip Morris fails to acknowledge its role as a cigarette manufacturer. As a form of corporate sponsorship Philip Morris thought its involvement could evade any European tobacco advertising ban.
Conclusions: Philip Morris is using a tourist attraction to promote its views on control of second hand smoke (SHS) and accommodation of smokers and non-smokers in the indoor environment. However, ventilation does not deal with the health effects of SHS. Policymakers must be cognisant of the devious tactics the industry employs to promote its own agenda, especially in relation to indoor air quality and smoking in public places. Tobacco control legislation should be continually modified and strengthened in response to the changing activities of the tobacco industry as it strives to evade existing legislation and deter the advent of new legislation.
相似文献Design: A random-digit-dial telephone survey was conducted with 616 adult smokers in south western Ontario, Canada in October/November 2001, with three month follow up.
Main outcome measures: Smoking behaviour (quitting, quit attempts, and reduced smoking), intentions to quit, and salience of the warning labels.
Results: Virtually all smokers (91%) reported having read the warning labels and smokers demonstrated a thorough knowledge of their content. A strong positive relation was observed between a measure of cognitive processing—the extent to which smokers reported reading, thinking about, and discussing the new labels—and smokers' intentions to quit (odds ratio (OR) 1.11, 95% confidence interval (CI) 1.07 to 1.16; p < 0.001). Most important, cognitive processing predicted cessation behaviour at follow up. Smokers who had read, thought about, and discussed the new labels at baseline were more likely to have quit, made a quit attempt, or reduced their smoking three months later, after adjusting for intentions to quit and smoking status at baseline (OR 1.07, 95% CI 1.03 to 1.12; p < 0.001).
Conclusions: Graphic cigarette warning labels serve as an effective population based smoking cessation intervention. The findings add to the growing literature on health warnings and provide strong support for the effectiveness of Canada's tobacco labelling policy.
