Tobacco Control最新文献

Background: The tobacco industry has spent millions of dollars promoting racialised narratives against the US Food and Drug Administration's recently announced ban on menthol as a characterising cigarette flavour. This research investigates racialised narratives in online discourse following the ban's announcement.

Methods: Tweets and users responding to the April 2022 menthol ban announcement were content analysed to examine the influence of tobacco industry affiliates and potentially organic African-American/Black (AA/B) users. Next we investigated the extent to which the menthol ban was discussed on AA/B subreddits and used Latent Dirichlet Allocation topic modelling to provide an overview of the menthol ban discussion on Reddit.

Results: Only 28 (13.9%) tweets by 22 users claimed that the menthol ban would lead to police violence and/or racial discrimination. Of users who tweeted about over-policing, eight (36.4%) had financial connections to the tobacco industry. There were only three tweets receiving a combined seven retweets from potentially organic AA/B users. On Reddit, only two posts with one comment discussed the menthol ban on subreddits dedicated to AA/B issues and culture. Topic modelling showed that the most common topic related to the menthol ban involved the social and political implications of the ban followed by illicit markets and protecting youth.

Conclusion: Tweets claiming a menthol ban will lead to police violence are indicative of industry agenda-setting. The menthol ban was not a prominent topic of discussion in AA/B subreddits although users discussing news and politics expressed concern for how AA/B people would respond to a ban politically.

Introduction: Significant progress has been made in reducing maternal exposure to tobacco smoke and subsequent adverse birth outcomes, however, reductions may require strategies that reduce the availability of tobacco retailers. In this study, we investigated the relationship between tobacco retailer density and birth outcomes across the USA and predicted the potential impact of a tobacco retailer density cap on these outcomes.

Methods: Annual US county (n=3105), rates of preterm birth, low birth weight, small-for-gestational age, all-cause infant mortality and sudden infant death syndrome (SIDS) were calculated using National Vital Statistics System data. Tobacco retailers were identified from the National Establishment Time-Series Database. We used Poisson regression to estimate the effect of capping retailer density at 1.4 retailers per 1000 population, controlling for county demographics and air pollution, using propensity score weighting.

Results: Tobacco retailer density was positively associated with most adverse birth outcomes. We estimate that a nationwide cap on tobacco retailer density, implemented in 2016, would have resulted in a reduction of 4275 (95% CI 2210 to 6392) preterm births, 6096 (95% CI 4421 to 7806) small-for-gestational-age births, 3483 (95% CI 2615 to 4378) low birthweight births, 538 (95% CI 345 to 733) all-cause infant deaths and 107 (95% CI 55 to 158) SIDS deaths in that year.

Conclusion: Higher rates of adverse birth outcomes were seen in counties with high tobacco retailer density compared with those with low density. These results provide further support for regulating tobacco retail density to reduce adverse health outcomes associated with tobacco use.

Introduction: Previous studies have identified pricing strategies that the tobacco industry employs to try to minimise the impact of tobacco taxation, but these studies are mostly about high-income countries. This research examines industry price responses to a recent cigarette tax increase in Mexico, including in the capsule cigarette segment that has expanded rapidly in Latin America.

Methods: Data of cigarette prices and sales in Mexico between October 2018 and September 2021 licensed from NielsenIQ were used following a quasi-experimental design to analyse price changes after excise tax increases with fixed effect models by product. To explore heterogeneous responses, estimates were disaggregated by cigarette attributes such as presence of capsules and market segment. Differential shifting was also assessed.

Results: Increasing the tobacco tax from 2011MX$0.35( ≈ US$0.02) to 2020 MX$0.4944( ≈ US$0.0283) in January 2020 was associated with an overall 8% cigarette price increase in real terms. However, some cigarette types, including premium to discount segments, exhibited price increases larger than the tax increase, which reduced the relative price of ultra-low-priced cigarettes. Instead of a single hike, prices were gradually raised throughout the first months of 2020 for all cigarette types. A combination of both pricing strategies was employed for capsule cigarettes. The 2021 smaller tax adjustment for annual inflation was fully passed onto consumer, maintaining real prices constant.

Conclusions: The industry's ability to raise prices more than the tax increase and manage these price increases smoothly suggests that there was room for larger tobacco tax increases in Mexico. Future developments on tobacco taxes could consider a fully specific tax structure or minimum taxes to mitigate the adverse effects of market segmentation and differential shifting.

Objective: We examined the relationship in Australia from 2007 to 2020 between tobacco tax increases and use of cost-minimising behaviours (CMBs) when purchasing tobacco and: (1) tobacco expenditure and (2) smoking cessation attempts and quit success.

Methods: We used data collected from adults who smoked factory-made and/or roll-your-own (RYO) cigarettes in nine waves (2007-2020) of the International Tobacco Control Policy Evaluation Project Australia Survey (N_sample=4975, N_observations=10 474). CMBs included buying RYO tobacco, cartons, large-sized packs, economy packs, or tax avoidance/evasion, smoking reduction and e-cigarette use. Logistic regression, fit using generalised estimating equations, estimated the CMB-outcome association for quit attempts and quit success at the next wave follow-up (N_subsample=2984, N_observations=6843).

Results: Over half of respondents used a CMB for tobacco purchase (P-CMB) at baseline (57.1% in 2007-2008), increasing to 76.8% (2018) post-tax increases. Participating in any P-CMB was associated with having higher weekly tobacco expenditure. Engaging in any P-CMB was negatively associated with attempting to quit (aOR=0.82, 95% CI 0.69-0.98). Purchasing RYO tobacco or cartons was associated with making no quit attempts (aOR=0.66, 95% CI 0.52-0.83; aOR=0.72, 95% CI 0.59-0.89, respectively). Among respondents smoking cigarettes who made quit attempts, there were no significant associations between all P-CMBs and quit success. Neither smoking reduction nor vaping were significantly associated with quit attempts.

Conclusion: P-CMBs are associated with reduced smoking cessation. Reducing opportunities for industry to promote purchasing-related CMB options, such as by standardising pack sizes and reducing the price differential between RYO and manufactured cigarettes could increase the effectiveness of tax increases.

Background: Nicotine products increasingly contain synthetic nicotine made in a lab (NML), not from tobacco. 'Tobacco-free nicotine' is most often used to describe NML commercially, but other descriptors are emerging (eg, 'non-tobacco,' 'zero-tobacco'). We examined whether terms for NML differentially impact public understanding of nicotine source or risk perceptions relative to each other and to terms for describing nicotine from tobacco (NFT) as 'tobacco-derived.'

Methods: From December 2022 to April 2023, 1000 participants aged 13 and older completed an online survey (mean age: 33.02 (SD=18.15) years, 50.5% female, 16.6% Hispanic, 67.4% White and 79.8% with current tobacco use). Participants read 11 terms describing nicotine and reported on perceived nicotine source (ie, NML, NFT) and addictiveness. Rank-ordered harm was included as a sensitivity analysis.

Results: Significant differences were observed among terms (eg, 'zero tobacco nicotine' and 'no tobacco nicotine' were rated as least addictive overall). 'NML' and 'NFT' adequately conveyed nicotine source and were rated as conveying comparable, yet high addictiveness, making them the optimal terms.

Conclusions: Many terms for NML and NFT are differentially related to understanding nicotine source and risk perceptions even though no existing research indicates that NML and NFT differ meaningfully from each other on characteristics like addictiveness. In the absence of prohibiting product differentiation by nicotine source, regulatory agencies should promote using the terms 'Nicotine from Tobacco' and 'Nicotine Made in a Lab' and investigate whether products using descriptors conveying reduced harm (eg, 'zero-tobacco,' 'no-tobacco,' 'non-tobacco') should require review as Modified Risk Tobacco Products.

Health warnings and messages-or health warning labels (HWLs)-are integral to tobacco control efforts, but their sustained impact necessitates regular rotation. This paper explores challenges in HWL rotation implementation across six diverse countries: Chile, Guyana, Indonesia, Jamaica, Mexico, and Vietnam. 19 in-depth interviews were conducted with government officials and representatives from civil society organisations and academia. Interviews explored the effectiveness of HWL regulations, the processes involved in their execution, and any challenges encountered along the way. Interviews were analysed thematically, using a combination of deductive and inductive approaches. Interviews revealed critical challenges that fall into two categories: specific and overarching. Government priorities and transitions, political will, time and bureaucracy, legal loopholes, lack of images, evaluation, and economic and human resources constitute HWL-specific challenges. Broad tobacco control challenges included tobacco industry interference and enforcement difficulties. To address HWL rotation challenges, international bodies such as WHO could establish extensive image banks, pre-evaluated for effectiveness and cultural relevance. In addition, countries must institutionalise the rotation process by establishing mechanisms that avoid having to pass complex legal instruments with each new round of warnings, delegating responsibilities to stable government institutions, addressing legal loopholesand planning for multiple rounds within a single legal instrument. Further, partnerships at national and international levels, along with systematic evaluations, are crucial for successful HWL implementation. These recommendations form a comprehensive framework for global collaboration, aiming to strengthen tobacco prevention through impactful HWLs on a sustainable basis.

Objective: Although Brazil became the first country worldwide to ban the sale of all tobacco products with any additive that could alter their flavours and tastes in 2012, its implementation was effectively halted by tobacco industry lawsuits, including a constitutional challenge filed in the Federal Supreme Court in 2013. This study aimed at examining, for the first time in the country, the evolution over time of the new registrations of tobacco products with additives that would have been banned if not for the tobacco industry's interference ('counterfactual scenario').

Methods: We used the newly available public database on the registration of tobacco products developed by the Health Regulatory Agency (from 2008 onwards). All types of tobacco products intended for the domestic market that contained 'banned additives in a counterfactual scenario' and were registered between January 1 and December 31 of each year were selected.

Results: Between 2012 and 2023, a total of 1112 new registrations of tobacco products with 'banned additives' were recorded. The spread of hookah tobacco registrations started in 2014, and by 2023, the cumulative incidence of registrations containing 'banned additives' was 641. Both manufactured cigarettes and hookah products reached their peaks in new registrations in 2020.

Conclusions: After 12 years since the resolution intended to ban all additives that change the aroma and taste of tobacco products in Brazil, primarily to prevent smoking initiation, the tobacco industry's interference continues to successfully block its implementation. Countries facing similar challenges in tobacco control could consider generating comparable national data that might help expose the adverse impacts of tobacco industry interference on public health.

Background: In 2017, Indonesia initiated the amendment of its 11-year-old tobacco control regulation (PP 109/2012) to reduce smoking among youth, but the process was stalled. The proposed changes in the regulation include a full ban on tobacco advertising, promotion and sponsorship (TAPS), increasing health warning label (HWL) size and regulating electronic cigarettes (e-cigarettes). This study analysed the arguments and actors for and against the PP 109/2012 amendment in online media articles.

Method: Content analysis of 326 online articles reporting on the PP 109/2012 amendment published from 2018 to 2023, retrieved from the Tobacco Watcher platform. We coded articles for statements supporting or opposing the amendment (position statement), content of the arguments used to support (supporting argument) and oppose (opposing argument) the amendment, actors presenting the arguments and tobacco control measures. We iteratively reviewed and coded data and presented the frequency of categories.

Results: Of 332 position statements, 53.3% were against the amendment. The main categories of supporting arguments (N=1448) included smoking trends (21.1%), health implications (16.6%), science-based evidence (9.6%) and protecting the population (9.2%). Opposing arguments (N=1413) emphasised the tobacco farmers' welfare (16.6%), impact on the industry (16.4%) and current regulation is sufficient (11.0%). Supporting actors were predominantly health-related entities and government officials (89.3%), while 62.1% of opposing actors included trade and Islamic groups, the tobacco industry and front groups. HWLs, e-cigarette/heated tobacco product regulation and TAPS were the main (77.8%) tobacco control measures mentioned in the proamendment arguments, while HWLs, TAPS and cigarette sale restrictions were the dominant (79.3%) tobacco control measures in anti-amendment arguments.

Conclusion: Indonesia's tobacco control reform faced opposition by false claims primarily from industry allies, resulting in a 5-year delay in enactment. Future tobacco control media advocacy must address these claims and emphasise the alignment of economic interests with public health goals.
