The influence of societal individualism on a century of tobacco use: modelling the prevalence of smoking

Predicting the long-term effects of electronic cigarette use on population health: a systematic review of modelling studies

OBJECTIVE

To systematically review and synthesise the findings of modelling studies on the population impacts of e-cigarette use and to identify potential gaps requiring future investigation.

DATA SOURCE AND STUDY SELECTION

Four databases were searched for modelling studies of e-cigarette use on population health published between 2010 and 2023. A total of 32 studies were included.

DATA EXTRACTION

Data on study characteristics, model attributes and estimates of population impacts including health outcomes and smoking prevalence were extracted from each article. The findings were synthesised narratively.

DATA SYNTHESIS

The introduction of e-cigarettes was predicted to lead to decreased smoking-related mortality, increased quality-adjusted life-years and reduced health system costs in 29 studies. Seventeen studies predicted a lower prevalence of cigarette smoking. Models that predicted negative population impacts assumed very high e-cigarette initiation rates among non-smokers and that e-cigarette use would discourage smoking cessation by a large margin. The majority of the studies were based on US population data and few studies included factors other than smoking status, such as jurisdictional tobacco control policies or social influence.

CONCLUSIONS

A population increase in e-cigarette use may result in lower smoking prevalence and reduced burden of disease in the long run, especially if their use can be restricted to assisting smoking cessation. Given the assumption-dependent nature of modelling outcomes, future modelling studies should consider incorporating different policy options in their projection exercises, using shorter time horizons and expanding their modelling to low-income and middle-income countries where smoking rates remain relatively high.

Racial/ethnic minority females smoke more cigarettes after social interaction with others who smoke

The present study investigated the effects of social interaction with others who smoke on daily cigarette use among diverse females via ecological momentary assessment methods. Ninety-eight premenopausal females (29.6% White, 70.4% racial/ethnic minority) who smoke daily reported their social interactions and cigarette use over 35-days. Greater than usual levels of social interaction with others who smoke was associated with increased cigarette use that day among racial/ethnic minority females. Future smoking cessation interventions targeting racial/ethnic minority females should consider the impact of social environments on smoking behaviors, such as the frequency of peer interactions with others who smoke.

The association between cultural and social occasions and smoking cessation: The case of Saudi Arabia

INTRODUCTION

Tobacco use remains high in Saudi Arabia, necessitating an understanding of the influence of cultural and social events on smoking cessation. This study examined whether cultural and social events like Ramadan, Eids, and birthdays, motivate Saudi adults to quit smoking.

METHODS

Convenience sampling of 742 Saudi tobacco users was conducted between July 2021 and May 2022. A cross-sectional survey was used to assess self-reported desire to quit (1 = 'least desire' to 10 = 'highest desire') and behaviors in relation to special occasions. Multiple linear regression was performed to examine the association between cultural and social occasions and the desire to quit, while logistic regression was used to assess the relationship between cultural and social occasions and historical quit attempts, medicinal nicotine product use, visiting smoking cessation clinics, and calling the national Quitline. Demographic variables and tobacco types were controlled for in the analyses.

RESULTS

Considering quitting during Ramadan, Eids, and birthdays was associated with a higher desire to quit (Ramadan: B=2.99; 95% CI: 2.51-3.47, Eids: B=2.83; 95% CI: 2.12-3.54, and birthdays: B=2.76; 95% CI: 1.93-3.60, p<0.01) and a greater likelihood of past quit attempts (Ramadan: AOR=8.2; 95% CI: 5.5-12.1, Eids: AOR=5.8; 95% CI: 3.2-10.5, and birthdays: AOR=4.8; 95% CI: 2.4-9.4). Only considering quitting during Ramadan was associated with calling the national Quitline (AOR=2.9; 95% CI: 1.8-4.9).

CONCLUSIONS

Cultural and social events like Ramadan and Eids motivate adults in Saudi Arabia to attempt tobacco cessation. Targeting interventions around meaningful cultural occasions may promote successful quitting. These findings highlight the importance of understanding cultural and religious influences on cessation behaviors in Saudi Arabia and in other countries.

Imaginal Retraining Reduces Craving for Tobacco in 1-Year Controlled Follow-Up Study

INTRODUCTION

Imaginal retraining is a self-help technique that adapts the principles of approach bias modification to the imagination. Imaginal retraining has been shown to reduce craving and addictive behaviours in 3 randomized controlled trials (RCTs) on problematic alcohol consumption, overweight, and tobacco use. To date, there have been no studies evaluating the long-term efficacy of the intervention. The aim of the present study was to generate first hypotheses on the long-term efficacy of imaginal retraining in smokers in a controlled 1-year follow-up study.

MATERIALS AND METHODS

We recontacted the 345 participants who had taken part in an RCT on imaginal retraining for smokers 1 year later. The survey was carried out online and assessed craving for tobacco (primary outcome), smoking behaviour, well-being, and subjective appraisal. Individuals who applied the technique at least once during the previous year were categorized as the training group, whereas participants who never performed the training were categorized as the no-training group. Data were analysed using linear mixed models (LMMs). The study was preregistered as DRKS00021044.

RESULTS

The completion rate was 45.5%. Less than 40% used the intervention at least once in the previous 12 months. LMM analyses showed a significant reduction in craving for tobacco for the training compared to the no-training group after 1 year. No significant group differences emerged in smoking behaviour, depressive symptoms, or quality of life. Subjective appraisal of the intervention was favorable, similar to the initial study.

CONCLUSION

The present study provides preliminary support for the long-term efficacy of imaginal retraining on craving for tobacco but not on smoking behaviour, highlighting the importance of multimodal treatment concepts in smoking cessation that target a variety of maintaining factors. Future studies need to investigate the long-term efficacy of the intervention in prospective RCTs that test alternative ways of conveying the technique to improve adherence.

Imaginal Retraining Reduces Cigarette Smoking: A Randomized Controlled Study

OBJECTIVES

Smoking is a highly prevalent addictive behavior with severe and life-shortening health consequences. This is the first study to evaluate the efficacy of a newly developed imaginal variant of approach bias modification (ABM) (i.e., imaginal retraining) for the reduction of craving for tobacco and actual smoking behavior.

METHODS

We randomized 345 smokers to imaginal retraining (self-help manual) or a control group (either active control or wait-list control). Assessments were carried out online. The treatment interval was 6 weeks. Craving for tobacco represented the primary outcome. The study was registered as DRKS00016860.

RESULTS

Retention was 79.7% with no difference between groups. The intention-to-treat (ITT) analyses were significant for the primary outcome (Visual Analogue Scale on craving for tobacco) as well as subjective reduction of smoking (45.5 vs. 26.4%) in favor of imaginal retraining. In the treatment group, 47.6% performed the exercises at least once. This subgroup (per-protocol [PP] sample) showed a significant reduction in tobacco dependency as measured with the Cigarette Dependence Scale (short and long forms) and the Fagerström Test for Nicotine Dependence relative to controls. Number of daily cigarettes declined to a greater extent in imaginal retraining in the PP but not ITT analysis. A small dose-effect relationship emerged between craving and frequency of performance of the technique.

CONCLUSION

When used regularly, imaginal retraining may reduce craving for tobacco and actual smoking behavior in a subgroup of smokers. In view of the large subgroup that did not read the manual or did not perform the exercises, alternative ways of conveying the imaginal retraining technique should be sought (e.g., demonstration via video clips). To conclude, imaginal retraining may represent a simple low-threshold technique to reduce smoking and assist current evidence-based treatment programs targeted at abstinence. It needs to be tested whether its mechanism of action deviates from standard ABM.
