Boosting self-efficacy and improving practices for smoking prevention and cessation among South American cancer care providers with a web-based algorithm.

BACKGROUND: Digital technologies have positively impacted the availability and usability of clinical algorithms through the advancement in mobile health. Therefore, this study aimed to determine if a web-based algorithm designed to support the decision-making process of cancer care providers (CCPs) differentially impacted their self-reported self-efficacy and practices for providing smoking prevention and cessation services in Peru and Colombia. METHODS: A simple decision-making tree algorithm was built in REDCap using information from an extensive review of the currently available smoking prevention and cessation resources. We employed a pre-post study design with a mixed-methods approach among 53 CCPs in Peru and Colombia for pilot-testing the web-based algorithm during a 3-month period. Wilcoxon signed-rank test was used to compare the CCPs' self-efficacy and practices before and after using the web-based algorithm. The usability of the web-based algorithm was quantitatively measured with the system usability scale (SUS), as well as qualitatively through the analysis of four focus groups conducted among the participating CCPs. RESULTS: The pre-post assessments indicated that the CCPs significantly improved their self-efficacy and practices toward smoking prevention and cessation services after using the web-based algorithm. The overall average SUS score obtained among study participants was 82.9 (± 9.33) [Peru 81.5; Colombia 84.1]. After completing the qualitative analysis of the focus groups transcripts, four themes emerged: limited resources currently available for smoking prevention and cessation in oncology settings, merits of the web-based algorithm, challenges with the web-based algorithm, and suggestions for improving this web-based decision-making tool. CONCLUSION: The web-based algorithm showed high usability and was well-received by the CCPs in Colombia and Peru, promoting a preliminary improvement in their smoking prevention and cessation self-efficacy and practices.

Extended cost-benefit analysis of tobacco taxation in Brazil.

BACKGROUND: Brazil has experienced a persistent and substantial reduction in the prevalence of smoking in the population since 2006 due to increased taxes on tobacco and other tobacco control policies. Despite the effectiveness of these measures, however, the socioeconomic costs of smoking are still very high. Tobacco taxation in Brazil plays an important role among the measures adopted to curb tobacco use. METHODS: The study combines data from the National Household Sample Survey of 2008 and the National Health Survey of 2013 and applies cross-section, pooled, and probit estimations, to estimate price elasticities of tobacco consumption by distinct population cohorts. The paper presents a comprehensive cost-benefit analysis resulting from a one-time tax increase on manufactured cigarettes using estimated conditional price elasticity of cigarette consumption and probability of smoking by income and age quartiles. FINDINGS: Each 10% price increase (BRL 0.54), due to higher tobacco taxes, reduces cigarette consumption by about 5%, and for poor smokers, it would lead to net income gains by about BRL 39.00 per month (in 2019 values). The highest net income effects were observed for the younger, aged between 15 and 29 years, and for middle-aged individuals, between 40 and 59 years old. Higher tobacco taxes lead to lower medical expenses on tobacco-related diseases and a longer, healthier and more productive life. Most importantly, this policy is progressive, as its economic effects are stronger for the poorer than for the richer according to the income quartiles. CONCLUSIONS: A tax increase that rises cigarette prices generates significant social benefits by reducing tobacco spending and medical expenses on tobacco-related diseases and raising future years of life and net income. The total benefits for the individual and the society go way beyond the public finance improvement.

The Mexico SimSmoke tobacco control policy model: Development of a simulation model of daily and nondaily cigarette smoking.

BACKGROUND: Nondaily smoking has been on the rise, especially in Mexico. While Mexico has strengthened its tobacco control policies, their effects on nondaily smokers have gone largely unexamined. We developed a simulation model to estimate the impact of tobacco control policies on daily and nondaily smoking in Mexico. METHODS: A previously validated Mexico SimSmoke model that estimated overall trends in smoking prevalence from 2002 through 2013 was extended to 2018 and adapted to distinguish daily and nondaily smoking prevalence. The model was then validated using data from Mexican surveys through 2016. To gauge the potential effects of policies, we compared the trends in smoking under current policies with trends from policies kept at their 2002 levels. RESULTS: Between 2002 and 2016, Mexico SimSmoke underestimated the reduction in male and female daily smoking rates. For nondaily smoking, SimSmoke predicted a decline among both males and females, while survey rates showed increasing rates in both genders, primarily among ages 15-44. Of the total reduction in smoking rates predicted by the model by 2018, tax policies account for more than 55%, followed by health warnings, cessation treatment, smoke-free air laws, and tobacco control spending. CONCLUSIONS: Although Mexico SimSmoke did not successfully explain trends in daily and nondaily smoking, it helps to identify gaps in surveillance and policy evaluation for nondaily smokers. Future research should consider appropriate measures of nondaily smoking prevalence, trajectories between daily and nondaily smoking, and the separate impact of tobacco control policies on each group.

Should Graphic Warning Labels Proposed for Cigarette Packages Sold in the United States Mention the Food and Drug Administration?

INTRODUCTION: Under the US Family Smoking Prevention and Tobacco Control Act, the US Food and Drug Administration (FDA) has the authority to implement graphic warning labels (GWLs) on cigarette packages. Neither the original labels proposed by the FDA nor the revised labels include a source to indicate sponsorship of the warnings. This study tests the potential impact of adding a sponsor to the content of GWLs. METHODS: We recruited adult smokers (N = 245) and middle-school youth (N = 242) from low-income areas in the Northeastern US. We randomly assigned participants to view one of three versions of the original FDA-proposed warning labels in a between-subjects experiment: no sponsor, "US Food and Drug Administration," or "American Cancer Society" sponsor. We tested the effect of varying sponsorship on source attribution and source credibility. RESULTS: Compared to unsponsored labels, FDA sponsorship increased source attributions that the FDA sponsored the labels among both middle-school, largely nonsmoking youth and adult smokers. However, sponsorship had no effect on source credibility among either population. CONCLUSIONS: We found no evidence that adding FDA as the source is likely to boost source credibility judgments, at least in the short term; though doing so would not appear to have adverse effects on credibility judgments. As such, our data are largely consistent with the Tobacco Control Act's provisions that allow, but do not require, FDA sponsorship on the labels. IMPLICATIONS: This study addresses the FDA's regulatory efforts by informing the possible design and content of future cigarette warning labels. Our results do not offer compelling evidence that adding the FDA name on GWLs will directly increase source credibility. Future work may test more explicit FDA source labeling and continue to examine the credibility of tobacco message content among high-priority populations.

Abordagem e tratamento do tabagismo / Approach and treatment of smoking

O Sistema Único de Saúde (SUS) tem papel fundamental no auxílio às pessoas que desejam parar de fumar. Para tanto, é muito importante que os profissionais atuantes na atenção básica e assistência à saúde estejam preparados para oferecer esse auxílio. Considerando esse contexto, a Diretoria de Vigilância Epidemiológica da Secretaria de Estado da Saúde de Santa Catarina (DIVE/SES/SC), por meio de sua Gerência de Análises Epidemiológicas e Doenças e Agravos Não Transmissíveis (GADNT) e a Escola de Saúde Pública de Santa Catarina (ESPSC) disponibilizam o curso "Abordagem e Tratamento do Tabagismo".

Parents' Self-efficacy for Tobacco Exposure Protection and Smoking Abstinence Mediate Treatment Effects on Child Cotinine at 12-Month Follow-up: Mediation Results from the Kids Safe and Smokefree Trial.

INTRODUCTION: Compared with the general smoking population, low-income smokers face elevated challenges to success in evidence-based smoking cessation treatment. Moreover, their children bear increased disease burden. Understanding behavioral mechanisms related to successful reduction of child tobacco smoke exposure (TSE) could inform future smoking interventions in vulnerable, underserved populations. METHODS: Smoking parents were recruited from pediatric clinics in low-income communities and randomized into a multilevel intervention including a pediatric clinic intervention framed in best clinical practice guidelines ("Ask, Advise, Refer" [AAR]) plus individualized telephone counseling (AAR + counseling), or AAR + control. Mediation analysis included treatment condition (independent variable), 12-month child cotinine (TSE biomarker, criterion), and four mediators: 3-month end-of-treatment self-efficacy to protect children from TSE and smoking urge coping skills, and 12-month perceived program (intra-treatment) support and bioverified smoking abstinence. Analyses controlled for baseline nicotine dependence, depressive symptoms, child age, and presence of other residential smokers. RESULTS: Participants (n = 327) included 83% women and 83% African Americans. Multilevel AAR + counseling was associated with significantly higher levels of all four mediators (ps < .05). Baseline nicotine dependence (p < .05), 3-month self-efficacy (p < .05) and 12-month bioverified smoking abstinence (p < .001) related significantly to 12-month child cotinine outcome. The indirect effects of AAR + counseling intervention on cotinine via self-efficacy for child TSE protection and smoking abstinence (ps < .05) suggested mediation through these pathways. CONCLUSIONS: Compared with AAR + control, multilevel AAR + counseling improved all putative mediators. Findings suggest that fostering TSE protection self-efficacy during intervention and encouraging parental smoking abstinence may be key to promoting long-term child TSE-reduction in populations of smokers with elevated challenges to quitting smoking. IMPLICATIONS: Pediatric harm reduction interventions to protect children of smokers from tobacco smoke have emerged to address tobacco-related health disparities in underserved populations. Low-income smokers experience greater tobacco-related disease burden and more difficulty with smoking behavior change in standard evidence-based interventions than the general population of smokers. Therefore, improving knowledge about putative behavioral mechanisms of smoking behavior change that results in lower child exposure risk could inform future intervention improvements.

¡Activate Ya! Co-learning about school-based tobacco prevention and physical activity promotion in secondary school students in Uruguay.

PURPOSE: ¡Activate Ya! was a group-randomized controlled intervention trial aimed at developing and evaluating the impact of a school-based intervention on preventing cigarette smoking and promoting physical activity (PA) in secondary school students in Uruguay. Secondary aims were to evaluate the program's impact on students' smoking- and PA-related psychosocial risk and protective factors. METHODS: Sixteen schools and n = 654 students participated in the study. The one-year intervention included a classroom-based curriculum, an afterschool program, activity breaks, and final showcase event. A self-administered questionnaire measured outcomes at three time points. Fixed effects regression models tested for differences in outcomes by study condition. RESULTS: While positive intervention effects were found for selected psychosocial-related smoking outcomes, no impact on past-year smoking or smoking susceptibility was detected. Past 7-day PA, measured by the PAQ-C, was significantly higher among intervention school students overall (p = .048) and for girls (p = .03) at posttest, and intervention girls reported significantly higher athletic identity PA competence, friend and teacher PA support at posttest, and PA enjoyment at follow-up (p < .05). CONCLUSION: The positive short-term effects of ¡Activate Ya! on PA and related outcomes for girls support the utility of school-based health promotion in Uruguay. Additional research is needed to determine the most effective strategies to prevent tobacco use among students and promote PA among boys in this setting.

Smoke-free legislation and neonatal and infant mortality in Brazil: longitudinal quasi-experimental study.

OBJECTIVE: To examine the associations of partial and comprehensive smoke-free legislation with neonatal and infant mortality in Brazil using a quasi-experimental study design. DESIGN: Monthly longitudinal (panel) ecological study from January 2000 to December 2016. SETTING: All Brazilian municipalities (n=5565). PARTICIPANTS: Infant populations. INTERVENTION: Smoke-free legislation in effect in each municipality and month. Legislation was encoded as basic (allowing smoking areas), partial (segregated smoking rooms) or comprehensive (no smoking in public buildings). Associations were quantified by immediate step and longer term slope/trend changes in outcomes. STATISTICAL ANALYSES: Municipal-level linear fixed-effects regression models. MAIN OUTCOMES MEASURES: Infant and neonatal mortality. RESULTS: Implementation of partial smoke-free legislation was associated with a -3.3 % (95% CI -6.2% to -0.4%) step reduction in the municipal infant mortality rate, but no step change in neonatal mortality. Comprehensive smoke-free legislation implementation was associated with -5.2 % (95% CI -8.3% to -2.1%) and -3.4 % (95% CI -6.7% to -0.1%) step reductions in infant and neonatal mortality, respectively, and a -0.36 (95% CI -0.66 to-0.06) annual decline in the infant mortality rate. We estimated that had all smoke-free legislation introduced since 2004 been comprehensive, an additional 10 091 infant deaths (95% CI 1196 to 21 761) could have been averted. CONCLUSIONS: Strengthening smoke-free legislation in Brazil is associated with improvements in infant health outcomes-particularly under comprehensive legislation. Governments should accelerate implementation of comprehensive smoke-free legislation to protect infant health and achieve the United Nation's Sustainable Development Goal three.

Fear or Humour in anti-smoking campaigns? Impact on perceived effectiveness and support for tobacco control Policies / Medo ou Humor em campanhas antitabágicas? O impacto na perceção de eficácia e apoio a políticas antitabágicas

Abstract Several anti-smoking campaigns have been used for decades to reduce smoking consumption. However, so far, there is no consensus regarding the effectiveness of inducing distinct emotions in reducing smoke consumption. This study tested the effects of two types of anti-smoking ads, inducing fear or humor, on emotions, perceived effectiveness, support for tobacco control policies, urges to smoke, and susceptibility to smoke. Participants (N = 108; 54 smokers) of both genders were randomly assigned to one of the two following emotion ads condition: fear (N = 52) or humor (N = 56). During exposure, the continuous flow of their emotions by self-report and physiologically was collected. Measures of ads impact on emotions, perceived effectiveness, urges and susceptibility to smoking, and support for tobacco policies were applied after exposure. The results have shown that fear ads were perceived as more effective and reduced the urges to smoke in smokers. Non-smokers were more supportive of tobacco control policies. In conclusion, this study showed that fear campaigns can reduce the urge to smoke among smokers and are perceived to be more effective. This perceived effectiveness can be partially explained by feelings of fear, regardless the other emotions it also triggers, and of the smoking status.

Resumo Várias campanhas antitabágicas são usadas para reduzir o consumo de tabaco. No entanto, até ao momento não existe um consenso sobre a eficácia da indução de emoções específicas nestas campanhas. Este estudo testou os efeitos de dois tipos de campanhas antitabágicas, induzindo Medo ou Humor, nas emoções, na perceção de eficácia das campanhas, no apoio a políticas antitabágicas, no desejo de fumar, e na suscetibilidade para fumar. Os participantes (N = 108; 54 fumadores), de ambos os sexos, foram aleatoriamente distribuídos para uma das seguintes campanhas indutoras de emoções: medo (N = 52) ou humor (N = 56). Durante a exposição, registou-se o fluxo contínuo das emoções autorreportadas e as respostas fisiológicas. Após a exposição avaliou-se o impacto das campanhas nas emoções, na perceção de eficácia, nas políticas antitabágicas, no desejo e na suscetibilidade para fumar. Os resultados evidenciaram que as campanhas indutoras de medo foram percecionadas como mais eficazes e reduziram o desejo de fumar em fumadores. Políticas antitabágicas foram mais apoiadas por não fumadores. Futuramente deverá considerar-se que induzir diferentes emoções em campanhas antitabágicas pode ter efeitos distintos a nível afetivo e cognitivo, com possível relevância para a mudança comportamental.

Campanhas educativas de controle do tabagismo: do vício moral ao estilo de vida saudável / Educational smoking control campaigns: from moral addiction to healthy lifestyle / Campañas educativas de control de fumadores: de la adicción moral al estilo de vida saludable

Este artigo é resultado do trabalho de pesquisa sobre a produção das campanhas antitabagistas de governo e sobre a forma com que foram apropriados pela população. Nosso objetivo foi avaliar como essas campanhas foram pensadas em relação aos princípios de comunicação e saúde pressupostos pelo Sistema Único de Saúde. A expectativa foi problematizar a questão numa perspectiva interdisciplinar. Analisamos documentos a partir dos preceitos teóricos e metodológicos da Semiologia dos Discursos Sociais. Concluiu-se que foram criadas campanhas alarmistas, pautadas na imputação do medo e na vigília moral, que acabaram por se distanciar da ideia de uma comunicação em saúde pública dialógica, informativa e participativa.

This article is the result of a research on the use of the concept of aversion in the production of government anti-smoking campaigns and how they were appropriated by the population. Our objective was to evaluate how these campaigns were conceived in relation to the principles of communication and health presupposed by the Unified Health System. The expectation was to problematize the issue from an interdisciplinary perspective. We analyze documents from the theoretical and methodological precepts of Semiology of Social Discourses. It was concluded that alarmist campaigns were created, based on the imputation of fear and on moral vigilance, which eventually distanced these actions from the principles of communication in dialogic, informative and participatory public health.

Facebook recruitment of smokers: comparing gain- and loss-framed ads for the purposes of an Internet-based smoking cessation intervention.

Gain- and loss-framed messages about smoking behavior have commonly been used to promote cessation. However, there are still no clear conclusions as to what kind of message is more effective for motivating smokers to quit. This study compared the effectiveness of loss- and gain-framed messages in the online recruitment of smokers via Facebook Advertising. Loss- and gain-framed messages about smoking were created and released as Facebook ads. Users who clicked on the ads were automatically redirected to the "Live Without Tobacco" intervention (http://www.vivasemtabaco.com.br). The amount spent on the ads was BRL 647.64. Data were collected from the Facebook Ads platform and from a relational database. Analyses were performed on the 6,350 users who clicked on one of the ads and 1,731 who were successfully redirected to the intervention. Gain-framed ads reached 174,029 people and loss-framed ads reached 180,527. The former received 2,688 clicks, while the latter received 3,662. The cost of the click was BRL 0.12 per gain-framed ad and BRL 0.09 per loss-framed ad. Loss-framed ads reached more users, got more clicks (and website accesses), and led to more accounts and quit plans being created. Loss-framed messages about smoking appear to be more cost-effective for both initial recruitment and intervention engagement. Facebook has proven to be a good outreach and recruitment tool and can be a solution for the difficulty in reaching smokers for cessation interventions.

Burden of smoking in Brazil and potential benefit of increasing taxes on cigarettes for the economy and for reducing morbidity and mortality. / Carga do tabagismo no Brasil e benefício potencial do aumento de impostos sobre os cigarros para a economia e para a redução de mortes e adoecimento.

The prevalence of smoking in Brazil has decreased considerably in recent decades, but the country still has a high burden of disease associated with this risk factor. The study aimed to estimate the burden of mortality, morbidity, and costs for society associated with smoking in 2015 and the potential impact on health outcomes and the economy based on price increases for cigarettes through taxes. Two models were developed: the first is a mathematical model based on a probabilistic microsimulation of thousands of individuals using hypothetical cohorts that considered the natural history, costs, and quality of life of these individuals. The second is a tax model applied to estimate the economic benefit and health outcomes in different price increase scenarios in 10 years. Smoking was responsible for 156,337 deaths, 4.2 million years of potential life lost, 229,071 acute myocardial infarctions, 59,509 strokes, and 77,500 cancer diagnoses. The total cost was BRL 56.9 billion (USD 14.7 billion), with 70% corresponding to the direct cost associated with healthcare and the rest to indirect cost due to lost productivity from premature death and disability. A 50% increase in cigarette prices would avoid 136,482 deaths, 507,451 cases of cardiovascular diseases, 64,382 cases of cancer, and 100,365 cases of stroke. The estimated economic benefit would be BRL 97.9 billion (USD 25.5 billion). In conclusion, the burden of disease and economic losses associated with smoking is high in Brazil, and tax increases are capable of averting deaths, illness, and costs to society.

A prevalência do tabagismo no Brasil reduziu sobremaneira nas últimas décadas, mas o país ainda tem uma elevada carga de doença associada a este fator de risco. O objetivo deste trabalho foi estimar a carga de mortalidade, morbidade e custos para a sociedade associada ao tabagismo em 2015 e o potencial impacto gerado em desfechos de saúde e para a economia a partir do aumento de preços dos cigarros por meio de impostos. Foram desenvolvidos dois modelos: o primeiro é um modelo matemático baseado em uma microssimulação probabilística de milhares de indivíduos usando-se coortes hipotéticas que considerou a história natural, custos e a qualidade de vida destes indivíduos. O segundo é um modelo de impostos aplicado para estimar o benefício econômico e em desfechos de saúde de diferentes cenários de aumento de preços em 10 anos. O tabagismo foi responsável por 156.337 mortes, 4,2 milhões de anos de vida perdidos, 229.071 infartos agudos do miocárdio, 59.509 acidentes vasculares cerebrais e 77.500 diagnósticos de câncer. O custo total foi de R$ 56,9 bilhões, dos quais 70% corresponderam ao custo direto associado à assistência à saúde e o restante ao custo indireto devido à perda de produtividade por morte prematura e incapacidade. Um aumento de 50% do preço do cigarro evitaria 136.482 mortes, 507.451 casos de doenças cardiovasculares, 64.382 de casos de câncer e 100.365 acidentes vasculares cerebrais. O benefício econômico estimado seria de R$ 97,9 bilhões. Concluiu-se que a carga da doença e econômica associada ao tabagismo é elevada no Brasil e o aumento de impostos é capaz de evitar mortes, adoecimento e custos para a sociedade.

EAT-Brazil Award for Tobacco Control: a brief description of its first edition.

Smoking is a major global risk factor for preventable death and disability. EAT is an acronym for Education Against Tobacco, a multinational network of physicians and medical students that aims to improve tobacco control by means of school-based prevention targeted at adolescents through counseling, use of software and support materials. The first EAT-Brazil Award, launched in March 2018, was a competition designed to encourage the proposal of objective solutions for tobacco control in Brasil, and identify new talents in the area. Brazilian undergraduate students from any field of study could submit a one-page essay on the subject, competing for the amount of R$ 1000.00 (one thousand reais). There were a total of 39 applicants (20 women and 19 men) from 9 Brazilian states and 18 undergraduate programs, with a mean age of 22.5 years (SD = 3.7). Data from an online anonymous questionnaire answered after the submission of their essays revealed that most applicants were students of institutions from in the state of Minas Gerais (n = 26/39; 66.6%), studied medicine (n = 20/39, 51.3%), and had no prior knowledge of the EAT-Brazil Network (n = 27/39, 69.2%). The winner of the award was Lucas Guimarães de Azevedo, a fourth-year medical student at Federal University of Western Bahia. The next editions of the award should focus on increasing the number of applicants and diversifying their geographical distribution.

RESUMO O tabagismo é um dos principais fatores de risco globais para morte e incapacidade evitáveis. EAT é a sigla em inglês para Educação contra o Tabaco (Education Against Tobacco), uma rede mundial formada por médicos e estudantes de medicina cuja missão é atuar no combate ao tabagismo por meio da prevenção da iniciação ao tabagismo em adolescentes escolares mediante aconselhamento, uso de aplicativos móveis e de materiais de apoio. O primeiro Prêmio EAT-Brazil, lançado em março de 2018, foi um concurso destinado a encorajar a proposição de soluções objetivas para o avanço do controle do tabagismo no país e a identificação de novos talentos para a área. Estudantes de graduação brasileiros de qualquer curso submeteram um texto de uma página sobre o tema, concorrendo à quantia de R$ 1.000. Houve um total de 39 trabalhos inscritos (20 por mulheres e 19 por homens) de nove estados brasileiros e 18 cursos de graduação, com idade média de 22,5 anos (DP=3,7). Dados de um questionário anônimo on-line respondido pelos inscritos revelou que a maioria era composta por graduandos de alguma instituição do estado de Minas Gerais (n=26/39; 66,6%), que estudavam medicina (n=20/39; 51,3%) e não tinham conhecimento prévio sobre a Rede EAT-Brazil (n=27/39; 69,2%). O ganhador do prêmio foi Lucas Guimarães de Azevedo, aluno do oitavo período de medicina da Universidade Federal do Oeste da Bahia. As próximas edições do Prêmio devem focar o aumento do número de inscritos e a diversificação de sua distribuição geográfica.

Cessação do tabagismo / Smoking cessation

O tabagismo é a principal causa evitável de morte, e é associado ao desenvolvimento de doenças cardiovasculares, respiratórias e câncer. Existem fortes evidências de que o controle do tabagismo tem boa relação de custo-efetividade quando comparado com outras intervenções de redução de riscos e prevenção de doenças. As bases da Convenção-Quadro para Controle do Tabaco da Organização Mundial da Saúde (CQCT/OMS) oferecem, por meio de artigos, guias e protocolos, rotina de atuação, além da oportunidade de colaboração e cooperação técnica entre os diversos países para abordar conjuntamente problemas que transcendem suas fronteiras. A OMS, objetivando facilitar a aplicação do tratado, lançou um pacote de intervenções para redução de demanda por produtos do tabaco de impacto comprovado, com experiência de implementação reconhecida e com políticas que podem ser aplicadas em qualquer país do mundo, o MPOWER. M >Monitor:monitorar da epidemia. P >Protect: proteger a população contra a fumaça do tabaco. O Offer:oferecer ajuda para deixar de fumar. W >Warn: advertir sobre os perigos do tabaco. E >Enforce: fazer cumprir a proibição da publicidade, promoção e patrocínio. R >Raise: aumentar impostos dos produtos do tabaco

Smoking is the leading avoidable cause of death, and is associated with the develo-pment of cancer, cardiovascular and respiratory diseases. There is strong evidence that tobacco control is cost-effective compared to other risk-reduction and disease prevention interventions. The bases of the World Health Organization Framework Convention on Tobacco Control (WHO FCTC) offer, through articles, guides and protocols, both a road map and the opportunity for collaboration and technical cooperation among the different countries to jointly address issues that transcend their borders. With a view to facilitating the implementation of the treaty, WHO has launched a package of interventions with proven impact, geared towards reducing the demand for tobacco products, with recognized implementation experience and policies that can be applied in any country in the world, MPOWER. M- Monitor tobacco use and prevention policies. P- Protect people from tobacco smoke. O- Offer help to quit tobacco use. W- Warn about the dangers of tobacco. E- Enforce bans on tobacco advertising, promotion and sponsorship. R- Raise taxes on tobacco

A Smoking Prevention Program Delivered by Medical Students to Secondary Schools in Brazil Called "Education Against Tobacco": Randomized Controlled Trial.

BACKGROUND: Smoking is the largest preventable cause of mortality in Brazil. Education Against Tobacco (EAT) is a network of more than 3500 medical students and physicians across 14 countries who volunteer for school-based smoking prevention programs. EAT educates 50,000 adolescents per year in the classroom setting. A recent quasi-experimental study conducted in Germany showed that EAT had significant short-term smoking cessation effects among adolescents aged 11 to 15 years. OBJECTIVE: The aim is to measure the long-term effectiveness of the most recent version of the EAT curriculum in Brazil. METHODS: A randomized controlled trial was conducted among 2348 adolescents aged 12 to 21 years (grades 7-11) at public secondary schools in Brazil. The prospective experimental design included measurements at baseline and at 6 and 12 months postintervention. The study groups comprised randomized classes receiving the standardized EAT intervention (90 minutes of mentoring in a classroom setting) and control classes in the same schools (no intervention). Data were collected on smoking status, gender, social aspects, and predictors of smoking. The primary endpoint was the difference in the change in smoking prevalence between the intervention group and the control group at 12-month follow-up. RESULTS: From baseline to 12 months, the smoking prevalence increased from 11.0% to 20.9% in the control group and from 14.1% to 15.6% in the intervention group. This difference was statistically significant (P<.01). The effects were smaller for females (control 12.4% to 18.8% vs intervention 13.1% to 14.6%) than for males (control 9.1% to 23.6% vs intervention 15.3% to 16.8%). Increased quitting rates and prevented onset were responsible for the intervention effects. The differences in change in smoking prevalence from baseline to 12 months between the intervention and control groups were increased in students with low school performance. CONCLUSIONS: To our knowledge, this is the first randomized trial on school-based tobacco prevention in Brazil that shows significant long-term favorable effects. The EAT program encourages quitting and prevents smoking onset, especially among males and students with low educational background.

Reinforcement Enhancing Effects of Nicotine Via Patch and Nasal Spray.

INTRODUCTION: Confirming preclinical findings, nicotine in humans (via smoking) enhances reinforcement from nondrug rewards. Recent demonstration of similar effects with nicotine via e-cigarettes suggests they may also occur when using nicotine replacement therapies (NRT). METHODS: Effects of nicotine via NRT patch or nasal spray were assessed on responding reinforced by music, video, or monetary rewards, or for no reward (control). Nontreatment seeking smokers (N = 31) participated in three virtually identical experimental sessions, each following overnight abstinence (CO ≤ 10 ppm). In a fully within-subjects design using a double-dummy procedure, these sessions involved: (1) nicotine patch (Nicoderm 14 mg) plus placebo spray, (2) placebo patch plus nicotine spray (Nicotrol, 2 × 1 mg/trial), or (3) placebo patch plus placebo spray. Session order was counter-balanced. RESULTS: Relative to placebo, reinforced responding due to nicotine via spray or patch was greater for video reward (both p < .01) but not for music reward (both p > .10). Similar results for NRT spray and patch confirms preclinical findings indicating no difference between fast and slow nicotine delivery, respectively, on reinforcement enhancing effects. Withdrawal relief was unrelated to these effects of nicotine via NRT on nondrug reinforcement. CONCLUSIONS: Nicotine from NRT has some reinforcement enhancing effects in humans, possibly in a manner consistent with nicotine via e-cigarettes but not tobacco smoking. Our findings could suggest differential dose-dependency of available rewards to enhanced reinforcement by nicotine. Such effects may help contribute to the efficacy of NRT for aiding smoking cessation, but more research focusing on dose-dependency of these nicotine actions is needed. IMPLICATIONS: Acute nicotine from smoking enhances reinforced responding for nondrug sensory rewards. Yet, nonsmoked nicotine, including from NRT medications of patch and nasal spray, may act more selectively across rewards, perhaps due to lower dosing exposure. Our results suggest that nicotine via NRT enhances responding for visual (video) reward, but not from auditory (music) reward, just as in prior results using e-cigarettes. Withdrawal relief from NRT was unrelated to reinforced responding, consistent with positive (and not negative) reinforcement from this nicotine. Further research evaluating the dose-response effects of nicotine may clarify differences in enhanced reinforcement depending on the type of available reward.

Distributional health and financial benefits of increased tobacco taxes in Colombia: results from a modelling study.

BACKGROUND: In Colombia, smoking is the second leading modifiable risk factor for premature mortality. In December 2016, Colombia passed a major tax increase on tobacco products in an effort to decrease smoking and improve population health. While tobacco taxes are known to be highly effective in reducing the prevalence of smoking, they are often criticised as being regressive in consumption. This analysis attempts to assess the distributional impact (across socioeconomic groups) of the new tax on selected health and financial outcomes. METHODS: This study builds on extended cost-effectiveness analysis methods to study the new tobacco tax in Colombia, and estimates, over a time period of 20 years and across income quintiles of the current urban population (80% of the country population), the years of life gained with smoking cessation and the increased tax revenues, all associated with a 70% relative price increase of the pack of cigarettes. Where possible, we use parameters that vary by income quintile, including price elasticity of demand for cigarettes (average of -0.44 estimated from household survey data). FINDINGS: Over 20 years, the tax increase would lead to an estimated 191 000 years of life gained among Colombia's current urban population, with the largest gains among the bottom two income quintiles. The additional annual tax revenues raised would amount to about 2%-4% of Colombia's annual government health expenditure, with the poorest quintiles bearing the smallest tax burden increase. CONCLUSIONS: The tobacco tax increase passed by Colombia has substantial implications for the country's population health and financial well-being, with large benefits likely to accrue to the two poorest quintiles of the population.

Temporal Effects of Message Congruency on Attention to and Recall of Pictorial Health Warning Labels on Cigarette Packages.

OBJECTIVES: Recent research has shown that message congruency is beneficial to recall of pictorial health warning label (PWL) content after initial exposure. Despite less attention to the text warning, smokers exposed to congruent PWLs were more likely to recall the text and the message. This study aimed to replicate these findings and to examine whether congruency also affects recall after multiple exposures over time. METHODS: A total of 320 daily smokers (39.7% female; cigarettes/day: M = 15.31, SD = 7.15) were randomized to one congruent or incongruent PWL and attended 4 laboratory sessions over 10 days. During each session, eye movements were recorded while viewing the PWL and open-ended recall of label content was assessed after exposure. RESULTS: Smokers who were exposed to a congruent PWL were more likely to recall the text (p = .01) and the message (p = .02) and less likely to recall the image (p = .003) of the PWL after initial exposure. By day 4, incongruent PWLs were recalled equally well as congruent PWLs. Independent of condition, image recall was initially high and remained high whereas text and message recall was relatively low initially but increased over time. It was not until day 7 that about 80% of text and message recall was observed. CONCLUSIONS: Even when exposed to the same PWL over time, smokers require multiple exposures to recall the text and the message of a PWL. More research on the effects of congruency in the natural environment, where smokers are exposed to multiple PWLs, is needed. IMPLICATIONS: The findings of this study, and of previous work showing that message congruency in PWLs is beneficial to initial recall of PWL content, could potentially help to address legal challenges regarding the implementation of PWLs in the United States. Factually correct text warnings have been uncontested on US cigarettes packages since 1966. Congruent PWLs simply provide a means to visually support the same information as the existing text using a medium that better garners attention to the health information. Investigating and understanding longer-term effects of congruency are important and can empirically inform future warning label development, both in the United States via the Family Smoking Prevention and Tobacco Control Act, and via other governing bodies.
