Tobacco Prevention & Cessation最新文献

Introduction: Smoking cessation reduces the risk of myocardial infarctions (MI) and death in patients with coronary heart disease. Smoking status is frequently assessed based on self-report. The aims of this study were to compare self-reported and objectively measured (exhaled carbon monoxide [eCO]) smoking status after MI, percutaneous coronary intervention (PCI), and coronary artery bypass grafting (CABG), and to assess whether assumed wrongly declared smoking cessation was associated to poorer achievement of other treatment targets for secondary prevention.

Methods: This study was a sub-analysis from a randomized controlled trial at Sorlandet Hospital, Arendal, Norway, 2007-2022, including patients hospitalized due to MI or after scheduled PCI/CABG, and primarily aimed at comparing secondary preventive follow-up in the outpatient clinic versus primary healthcare. Participants were followed up after the index event through outpatient consultations. Smoking status was assessed by self-report and by eCO (Smokerlyzer, Bedfont, UK) with concentration values ≥6 ppm interpreted as suggesting smoking.

Results: A total of 1540 participants aged 18-80 years were included in the main study. Self-reported smoking status and concomitant eCO measurement one year after the index event were available in 1291 (84%) participants. In all, Brussels, Belgium, from the 12th to the 13th of September 2024. The concentration of eCO was ≥6 ppm one year after the index event in 285 (22%) patients, and 72 (25%) of these patients reported non-smoking. Fewer patients with elevated eCO reporting non-smoking achieved the treatment target for blood pressure (<140/90 mmHg) in comparison to those reporting smoking (53% vs 68%, p=0.02). No differences for the other treatment targets for secondary prevention were found.

Conclusions: The study indicates a need for objective measures for smoking cessation both in clinical studies and in clinical practice, and may indicate a lack of truthfulness regarding smoking habits.

Clinical trial registration: The study is registered on the official website of ClinicalTrials.gov.

Introduction: The use of e-cigarettes is increasing worldwide, especially among young adults. Due to the health risks, this study aimed to assess undergraduate students' e-cigarette use and attitudes toward them, and evaluate the effectiveness of an intervention program to develop e-cigarette control leaders at the University in Lampang province, Thailand.

Methods: Participatory action research (PAR) was conducted among 46 undergraduate students. To assess the situations of undergraduate students' e-cigarette use and attitudes toward them, in-depth interviews were conducted with 18 of those students - nine users and nine non-users. The remaining 28 were student leaders who were given questionnaires and took part in focus groups to evaluate the effectiveness of the intervention program in developing e-cigarette control leaders. Descriptive statistics and the Wilcoxon signed rank test were used to analyze quantitative data. The qualitative data were analyzed using a thematic analysis of the content. This study took place at the University in Lampang province, Thailand, in 2023.

Results: Regarding the use of e-cigarettes on the part of undergraduate students and their attitudes about their use, the majority of users stated that e-cigarettes were accessible, appealing, and more socially acceptable than conventional cigarettes. However, most non-users cited vapor smell and health impacts as their main reason for not using e-cigarettes. The intervention program to develop leaders in e-cigarette control could significantly enhance the leaders' knowledge (p<0.001) and attitude regarding e-cigarettes (p=0.001). After their anti-e-cigarette campaign, the soft skills and managerial abilities of the leaders in e-cigarette control improved, and the knowledge and attitude regarding e-cigarettes of undergraduate students who attended the campaign also increased.

Conclusions: The intervention program to develop leaders in e-cigarette control resulted in positive outcomes. This program could enhance the leaders' knowledge and attitude regarding e-cigarettes. Their soft skills and managerial abilities in e-cigarette control also improved.

Introduction: E-cigarettes have rapidly gained a market share in South Africa and globally. Concerns have been raised over the growing popularity of e-cigarettes among young people, who are frequently drawn to these novel products and are especially targeted by marketers. Using a qualitative method, this study aimed to gain insight into young adults' knowledge, experiences, and perceptions of e-cigarette use in Cape Town, South Africa.

Methods: We conducted five focus groups (FGs) among students of the University of Cape Town (n=48; 46% females; 54% males; aged 18-25 years). These FGs, which included both e-cigarette users and non-users, were audio-taped, transcribed verbatim, and analyzed thematically using Nvivo 12 software.

Results: Despite their lack of information about the chemical constituents of e-cigarettes and their harm, participants perceived them as healthier than combustible cigarettes. Participants equated the pleasant smell and environmental friendliness of e-cigarettes with safety. The absence of e-cigarette regulation was interpreted as evidence of their safety. Participants indicated that the lack of anti-e-cigarette indoor policies, the deceptive marketing regarding their safety, and their low price compared to combustible cigarettes, had key roles in increasing young people's use of e-cigarettes.

Conclusions: Findings highlight factors at multiple levels contributing to e-cigarette use among young people in South Africa. Comprehensive strategies for e-cigarette regulation and prevention are needed. Potential strategies include increasing knowledge of e-cigarette harms through evidence-based communication campaigns and strengthening e-cigarette regulations by limiting e-cigarette advertisements, banning vaping in public places, and reducing the flavors used in e-cigarettes.

Introduction: Most US quitlines have quitsites and websites designated to promote their services. Quitsites have the potential to encourage LGBTQ individuals to utilize quitline services by explicitly mentioning the provision of LGBTQ-competent services. The present study audited quitsites to determine the presence of information regarding services for LGBTQ individuals.

Methods: Using a checklist consisting of nine criteria, a cross-sectional audit of the US quitsites was conducted between 16 October and 8 November 2023. The audit was divided into two phases: 1) auditors coded all quitsites separately, and 2) auditors met with the first author to compare their coding and reach a consensus. The inter-rater agreement was calculated. Frequencies and percentages were calculated for each criterion.

Results: Auditors evaluated a total of 46 quitsites. Inter-rater agreement was 96.85%. Seven quitsites (15.2%) met 0 of the nine criteria, and 36.9% of the quitsites (17/46) met more than six criteria. Only one quitsite met 8 of 9. No individual website met all nine criteria. While 84.8% of quitsites had at least a singular mention of the LGBTQ community somewhere on their website, only 4.3% of the quitsites mentioned the LGBTQ community on their landing page.

Conclusions: Most quitsites mentioned the LGBTQ community somewhere on their website (84.8%). However, only 4.3% of the quitsites mentioned the LGBTQ community on their landing page. Results suggest that quitsites explicitly mention the provision of services for LGBTQ individuals on their landing page, which has the potential to engage LGBTQ individuals into quitline services and reduce tobacco-related disparities.

Introduction: Armenia's and Georgia's high rates of smoking and secondhand smoke and recent implementation of smoke-free laws provide a timely opportunity to examine factors that increase compliance, like social enforcement and support for governmental enforcement.

Methods: Using 2022 data from 1468 Armenian and Georgian adults (mean age=42.92 years, 48.6% male, 31.6% past-month smoking), multilevel linear regression examined tobacco-related media exposures, social exposures, and perceptions/attitudes in relation to: 1) likelihood of asking someone to extinguish cigarettes where a) prohibited and b) allowed; and 2) support of fines for smoke-free violations (1=not at all to 4=very).

Results: There was low average likelihood of asking someone to extinguish cigarettes where allowed (mean=1.01, SD=1.12) or prohibited (mean=1.57, SD=1.21) and 'little' agreement with fines for smoke-free violations (mean=2.13, SD=1.06). Having fewer friends who smoked, greater support for indoor smoke-free laws, and no past-month cigarette use were positively associated with all 3 outcomes. Greater exposure to media and community-based action supporting smoke-free policies, and witnessing more requests to stop smoking where prohibited, were associated with higher likelihood of asking someone to extinguish cigarettes where allowed or prohibited. Less exposure to news stories opposing smoke-free policies and cigarette ads and higher perceived harm of cigarettes were also related to higher likelihood of asking someone to stop smoking where prohibited. Higher perceived harm of cigarettes was also associated with greater agreement with fines for smoke-free violations.

Conclusions: Comprehensive strategies targeting social norms, media exposure, and risk perceptions are needed to effectively facilitate strategies to enhance smoke-free law enforcement.

In the United States, the Food and Drug Administration (FDA) requires tobacco product manufacturers to submit Premarket Tobacco Product Applications (PMTA) for new products, granting marketing approval only if deemed appropriate for the protection of public health. Historically, the tobacco industry has exploited loopholes in the Tobacco Control Act (TCA), especially related to the definitions of nicotine, tobacco product and characterizing flavors, to circumvent the PMTA requirement. In 2023, the industry introduced several 'PMTA-exempt' e-cigarette and smokeless products, including products containing 6-methyl nicotine, a synthetic nicotine analog that is pharmacologically more potent than nicotine. In late 2023 and early 2024, the major US e-cigarette suppliers Nicotine River and ECBlend introduced 'PMTA-exempt' products with the brand names 'Nixamide' or 'Nixodine' or 'Nixotine', with nicotinamide as the main active ingredient. Nicotinamide is a form of vitamin B3 with no known pharmacological activity at nicotinic receptors. Here, we report that the marketing claims for these products, suggesting them and be nicotine substitute products designed to target nicotinic receptors and provide the same experience as nicotine, is deceptive and misleading to consumers. We also inform that these products have evolved further to contain a combination of nicotinamide and 6-methyl nicotine. The regulatory implications of these newly introduced products are discussed.

Introduction: It is unclear how young adults who do not use tobacco perceive FDA-authorized e-cigarettes for market entry. This study explored the perceptions and use interests of FDA-authorized e-cigarettes among this population to inform policy decision-making.

Methods: We conducted in-depth interviews with young adults in the US, aged 18-29 years, who do not use tobacco (n=25). Participants viewed images of FDA-authorized e-cigarettes and discussed their perceptions and interest in using these products. We used reflexive thematic analysis to analyze interview data.

Results: Many participants stated that they were not interested in using FDA-authorized e-cigarettes because they had little interest in using e-cigarettes in general. Additionally, almost all participants found the tobacco flavor and product design of these products unappealing, which further added to their disinterest. Most reported high trust in the FDA and its authorization process for e-cigarette market entry and considered FDA-authorized e-cigarettes safe to use. Most considered FDA-authorized products less harmful than other (unauthorized) e-cigarettes they saw in daily life but were not more interested in using the authorized products. When given the hypothetical scenario where FDA-authorized products come with a variety of fruit and candy flavors, most participants still expressed little interest in using them, mainly due to the high perceived harm from using any e-cigarette products.

Conclusions: Although non-tobacco-using young adults in our study reported low interest in using FDA-authorized e-cigarettes for market entry and e-cigarettes in general, the FDA is recommended to continue to evaluate the impact of flavorings and packages on e-cigarette product appeal to reduce e-cigarette use among young people. The FDA should also examine strategies to effectively communicate the purpose of FDA authorization to the public and emphasize that it does not mean these products are 'approved' or safer than unauthorized products.

Introduction: Financial incentives to stop smoking (FISS) programs have been implemented internationally to encourage people who smoke to quit smoking. However, such programs require that the financial reward structure and its resulting effects on smoking quit rates are considered. We analyzed a number of scenarios for FISS reward schedules for current smoking individuals in Ireland, with a view to identify the potential implications in terms of financial consequences and expected effects.

Methods: Using national QuitManager services data 2021-2023, we defined smoking quit rates for smokers currently using the national Health Services Executive stop smoking services in Ireland. Smoking quit rates at 4, 12 and 52 weeks were defined, and additionally defined by sex, age and education level. Using scenarios assuming different FISS reward sizes, structures and targeted population sub-groups, we estimated the number of additional quitters, budget impact, and incremental cost-effectiveness ratio.

Results: A FISS program, if implemented for a cohort of 3500 smokers can result in a budget impact ranging €250000 - €870000. The cost-effectiveness trade-off between different payment schedules and the expected effect size suggested that FISS are cost-effective even at a moderate effect size. A FISS program implemented to approximately 20000 smokers nationally would cost between €2.0 million and €4.8 million, subject to the chosen reward schedule. Across social groups, FISS is more cost-effective for females, individuals in the youngest age group, and individuals with a medium level of education.

Conclusions: This analysis highlights the importance of considering different FISS schedules and potential quit effects, when designing such programs. We highlight that FISS programs should be targeted at certain social groups to achieve highest long-term smoking cessation rates. We also identified important challenges that decision-makers face when designing the reward structure of FISS programs. The acceptability or otherwise of the FISS structures may differ among stakeholders and should be explored.
