The relationship between smokers' motivation to quit and intensity of tobacco control at the population level: a comparison of five European countries

Increase of unmotivated and hardened smokers in Hong Kong: a repeated cross-sectional trend analysis

OBJECTIVES

To examine the trends in the prevalence of hardening indicators and hardened smokers in Hong Kong, where the low smoking prevalence has plateaued in the recent decade.

METHODS

This is an analysis of repeated cross-sectional data from 9 territory-wide smoking cessation campaigns conducted annually from 2009 to 2018 (except 2011). Participants were 9837 biochemically verified daily cigarette smokers aged ≥18 years (18.5% female, mean age 43.2±14.2 years) recruited from the communities. Hardening indicators included heavy smoking (>15 CPD), high nicotine dependence (Heaviness of Smoking Index ≥5), no intention to quit within next 30 days and no past-year quit attempt. Perceived importance, confidence and difficulty of quitting were measured (each ranged 0-10). Multivariable regressions were used to model the changes in hardening indicators by calendar year, adjusting for sociodemographic characteristics.

RESULTS

From 2009 to 2018, the prevalence of heavy smoking decreased from 57.6% to 39.4% (p<0.001), high nicotine dependence also decreased from 10.5% to 8.6% (p=0.06). However, the proportion of smokers with no intention to quit (12.7%-69.0%) and no past-year quit attempt (74.4%-80.4%) significantly increased (both p values <0.001). Hardened smokers (heavy smoking, no intention to quit, no past-year attempt quit attempt) significantly increased from 5.9% to 20.7% (p<0.001). Mean perceived importance (from 7.9±2.3 to 6.6±2.5) and confidence (from 6.2±2.6 to 5.3±2.4) of quitting also decreased significantly (all p values <0.001).

CONCLUSIONS

Daily cigarette smokers in Hong Kong were motivational hardening, but not dependence hardening. Effective tobacco control policies and interventions are warranted to motivate quitting to further reduce smoking prevalence.

Hypnotherapy compared to cognitive-behavioral therapy for smoking cessation in a randomized controlled trial

Worldwide, more than eight million people die each year as a result of tobacco use. A large proportion of smokers who want to quit are interested in alternative smoking cessation methods, of which hypnotherapy is the most popular. However, the efficacy of hypnotherapy as a tobacco cessation intervention cannot be considered sufficiently proven due to significant methodological limitations in the studies available to date. The aim of the present study was to compare the efficacy of a hypnotherapeutic group program for smoking cessation with that of an established cognitive-behavioral group program in a randomized controlled trial. A total of 360 smokers who were willing to quit were randomly assigned to either hypnotherapy (HT) or cognitive-behavioral therapy (CBT) at two study sites, without regard to treatment preference. They each underwent a 6 weeks smoking cessation course (one 90 min group session per week) and were followed up at regular intervals over a 12 months period. The primary outcome variable was defined as continuous abstinence from smoking according to the Russell standard, verified by a carbon monoxide measurement at three measurement time points. Secondary outcome variables were 7 days point prevalence abstinence during the 12 months follow up and the number of cigarettes the non-quitters smoked per smoking day (smoking intensity). Generalized estimating equations were used to test treatment condition, hypnotic suggestibility, and treatment expectancy as predictors of abstinence. The two interventions did not differ significantly in the proportion of participants who remained continuously abstinent throughout the follow-up period (CBT: 15.6%, HT: 15.0%) and also regarding the 7 days abstinence rates during the 12 months follow-up (CBT: 21.2%, HT: 16.7%). However, when controlling for hypnotic suggestibility, CBT showed significantly higher 7 days abstinence rates. In terms of the continuous abstinence rates, it can be concluded that the efficacy of hypnotherapeutic methods for smoking cessation seem to be comparable to established programs such as CBT.

Factors associated with intentions to quit tobacco use in Lebanon: A cross-sectional survey

Introduction

The prevalence of tobacco smoking in Lebanon is among the highest globally. This study aims to determine past attempts to quit smoking among adults and identify factors associated with intentions to quit.

Methods

A nationally representative telephone survey was conducted between June and August 2022. Eligibility criteria included people aged >=18 years residing in Lebanon. The questionnaire was divided into three components: socio-demographic characteristics, cigarette and waterpipe tobacco use behaviours. Binary logistic regression was used to examine factors associated with intention to quit cigarette and waterpipe tobacco use.

Results

A total of 2003 respondents were included in the study. The prevalence of any tobacco product use was 41%, the prevalence of current cigarette smoking was 41% and the prevalence of current waterpipe tobacco use was 20%. Approximately 24% of adults who smoke cigarettes and 26% of those who use waterpipe tobacco had previous quit attempts mainly due to health concerns. Intentions to quit smoking within the next 6 months were reported among 12% of survey respondents. Among adults who smoke, past quit attempts increased the likelihood of intentions to quit cigarette smoking by 5-fold (OR: 5.11; 95% CI: 1.80-14.47, p = 0.002) and waterpipe tobacco use by 7-fold (OR: 6.98, 95% CI: 2.63-18.51, p = <0.001). Age and income were associated with intentions to quit cigarette but not waterpipe tobacco use.

Conclusion

Intention to quit smoking was strongly associated with past quitting attempts. Understanding factors associated with intentions to quit can help inform the development of context specific smoking cessation interventions.

Should Nicotine Replacement Therapy be Provided Free of Charge? A Cost-Utility Analysis in Sweden

INTRODUCTION

Treatment with nicotine replacement therapy (NRT) during an attempt to quit smoking increases the likelihood of success by about 55%. However, out-of-pocket payment for NRT can hinder its use.

AIMS AND METHODS

This study aims therefore to assess the cost-effectiveness of subsidizing NRT in Sweden. A homogeneous cohort-based Markov model was used to assess the lifetime costs and effects of subsidized NRT from a payer and societal perspective. Data to populate the model were retrieved from the literature, and selected parameters were varied in deterministic and probabilistic sensitivity analyses to assess robustness of model outputs. Costs are presented in USD, year 2021.

RESULTS

A 12-week treatment with NRT was estimated to cost USD 632 (474-790) per person. From a societal perspective, subsidized NRT was a cost-saving alternative in 98.5% of the simulations. NRT is cost-saving across all ages, but the health and economic gains are somewhat larger among younger smokers from a societal perspective. When a payer perspective was used, the incremental cost-effectiveness ratio was estimated at 14 480 (11 721-18 515) USD per QALY which was cost-effective at a willingness to pay of 50 000 USD per QALY in 100 % of the simulations. Results were robust with realistic changes in the inputs during scenario and sensitivity analyses.

CONCLUSIONS

Subsidizing NRT is potentially a cost-saving smoking cessation strategy from a societal perspective and cost-effective from a payer perspective.

IMPLICATIONS

This study found that subsidizing NRT is potentially a cost-saving smoking cessation policy alternative compared to current practice from a societal perspective. From a healthcare payer perspective, subsidizing NRT is estimated to cost USD 14 480 to gain an extra QALY. NRT is cost-saving across all ages, but the health and economic gains are somewhat larger among younger smokers from a societal perspective. Moreover, subsidizing NRT removes the financial barriers that are mostly faced by socioeconomically disadvantaged smokers which might reduce health inequalities. Thus, future economic evaluations should further investigate the health inequality impacts with methods that are more suitable for this.

Rauchen – Wissenswertes über Tabak und alternative Produkte

Tabakrauchen ist weltweit die häufigste vermeidbare Ursache für Krankheit und vorzeitigen Tod. Rauchen ist keine Life-Style-Entscheidung oder nur eine (schlechte) Angewohnheit. Es ist eine chronische Krankheit, die viele Erkrankungen mitverursacht und aggraviert. Durch das psychoaktive Nikotin ist Rauchen zusätzlich eine Suchterkrankung. Bei der Strategie zur Harm Reduction sollen Raucher die Tabakzigarette durch alternative nikotinhaltige Produkte („Alternative Nicotine Delivery Products“), wie die E-Zigarette oder Tabakerhitzer (Heat-not-burn-Produkte), ersetzen. Tabakkonzerne bewerben im Rahmen ihrer Marketingstrategie diese Produkte mit einer Schadstoffreduktion um 95%. Jedoch stehen unabhängige Forschungen und Langzeitergebnisse diesbezüglich aus. Raucher, die zu derartigen Produkten wechseln, sind durch die fortbestehende Nikotinabhängigkeit weiterhin langfristig den Belastungen durch (kardio)toxische und karzinogene Substanzen ausgesetzt. Die gesundheitlichen Auswirkungen dieser inhalativen Noxen werden dargestellt, wobei die Heat-not-burn-Produkte eine Mittelstellung zwischen der schädlichsten Tabakzigarette und den (möglicherweise) weniger gesundheitsschädlichen E-Zigaretten einnehmen. Das Fortbestehen einer (wenn auch reduzierten) kontinuierlichen Exposition in Verbindung mit einer Nikotinabhängigkeit ist keine Alternative zu einer professionellen evidenzbasierten multimodalen Tabakentwöhnung, die endlich flächendeckend (auch in Deutschland) angeboten werden muss. Ziel sollte der komplette Verzicht auf inhalative Noxen sein, ohne jegliche Toleranz für die Marketingstrategien der Tabakkonzerne.

E-cigarette use and conventional cigarette smoking among European students: findings from the 2019 ESPAD survey

BACKGROUND AND AIMS

Representative data on e-cigarette use among European adolescents are scant. This study reports current vaping and tobacco smoking individual and country-specific correlates among European students.

DESIGN

Cross-sectional survey: 2019 European School Survey Project on Alcohol and Other Drugs (ESPAD) collecting data on risk behaviours on a representative sample of 16-year-old students.

SETTING

A total of 35 European countries, 25-30 with Tobacco Control Scale (TCS) and TCS components PARTICIPANTS: A total of 99 648 students (49.1% males) turning 16 years in the survey year.

MEASUREMENTS

Data on current cigarette and e-cigarette use were gathered through a self-administered questionnaire which also collected socio-demographics and individual and family characteristics. ESPAD data were integrated with country-level data on TCS and selected TCS parameters to assess their association with the prevalence of current cigarette and e-cigarette use.

FINDINGS

Of the 99 648 participating students, 12.4% were current e-cigarette users, from 5.5% in Serbia to 41.4% in Monaco; 19.3% current smokers, from 5.1% in Iceland to 32.4% in Italy. Compared with non-users, current e-cigarette users less frequently came from an average well-off family [odds ratio (OR) = 0.85, 95% confidence interval (CI) = 0.80-0.90] and lived in countries with higher cigarette prices (OR = 0.71, 95% CI = 0.50-0.99), restrictive measures on tobacco advertising and promotion (OR = 0.79, 95% CI = 0.63-0.99) and intermediate implementation of tobacco control measures (OR = 0.57, 95% CI = 0.38-0.85). Current vapers were more frequently life ever smokers (OR = 7.31, 95% CI = 6.47-8.25), were early smokers (OR = 4.35, 95% CI = 3.66-5.17), males (OR = 1.61, 95% CI = 1.55-1.67), from non-traditional families (OR = 1.43, 95% CI = 1.34-1.53), with relatively low parental education (OR = 1.15, 95% CI = 1.10-1.20). Compared with non-smokers, current smokers had similar family characteristics to vapers, and were less likely to live in countries with higher cigarette prices (OR = 0.70, 95% CI = 0.49-0.99) and higher spending on public anti-tobacco media campaigns (OR = 0.23, 95% CI = 0.10-0.50).

CONCLUSIONS

E-cigarette use among European adolescents is associated with weaker tobacco control measures, particularly on tobacco price, advertising and promotion. Besides preventing tobacco smoking, the adoption of governmental tobacco control policies in European countries also seems to contribute to the prevention of vaping among adolescents.

Disentangling craving- and valence-related brain responses to smoking cues in individuals with nicotine use disorder

Tobacco smoking is one of the leading causes of preventable death and disease worldwide. Most smokers want to quit, but relapse rates are high. To improve current smoking cessation treatments, a better understanding of the underlying mechanisms of nicotine dependence and related craving behaviour is needed. Studies on cue‐driven cigarette craving have been a particularly useful tool for investigating the neural mechanisms of drug craving. Here, functional neuroimaging studies in humans have identified a core network of craving‐related brain responses to smoking cues that comprises of amygdala, anterior cingulate cortex, orbitofrontal cortex, posterior cingulate cortex and ventral striatum. However, most functional Magnetic Resonance Imaging (fMRI) cue‐reactivity studies do not adjust their stimuli for emotional valence, a factor assumed to confound craving‐related brain responses to smoking cues. Here, we investigated the influence of emotional valence on key addiction brain areas by disentangling craving‐ and valence‐related brain responses with parametric modulators in 32 smokers. For one of the suggested key regions for addiction, the amygdala, we observed significantly stronger brain responses to the valence aspect of the presented images than to the craving aspect. Our results emphasize the need for carefully selecting stimulus material for cue‐reactivity paradigms, in particular with respect to emotional valence. Further, they can help designing future research on teasing apart the diverse psychological dimensions that comprise nicotine dependence and, therefore, can lead to a more precise mapping of craving‐associated brain areas, an important step towards more tailored smoking cessation treatments.

Smoking Cessation and Vaping Cessation Attempts among Cigarette Smokers and E-Cigarette Users in Central and Eastern Europe

Our aim is to assess the smoking cessation and vaping cessation activity, including quit attempts and willingness to quit among university students in Central and Eastern Europe, as well as to investigate personal characteristics associated with smoking cessation and vaping cessation attempts. Data were collected by questionnaire which included 46 questions on cigarette and e-cigarette use. Questionnaires were obtained from 14,352 university students (aged 20.9 ± 2.4 years; cooperation rate of 72.2%). For the purposes of this analysis, only data from exclusive cigarette smokers (n = 1716), exclusive e-cigarette users (n = 129), and dual users (216) were included. Of all cigarette smokers, 51.6% had previously tried to quit smoking and 51.5% declared a willingness to quit cigarette smoking in the near future. Among all e-cigarette users only 13.9% had ever tried to quit using the e-cigarette and 25.2% declared a willingness to give up using e-cigarette in the near future. The majority of the group did not use pharmacotherapy to quit cigarette (87.5%) or e-cigarette (88.9%) use. Our results indicate that while most university students have some desire to quit conventional smoking, those who use e-cigarettes do not have the same desire.

Unplanned purchasing of tobacco products: Beyond point of sale display

ISSUE ADDRESSED

Tobacco products remain widely available and unplanned purchasing of tobacco has been implicated in cessation relapse. Little is known however about the frequency of consumers' unplanned tobacco purchases or the type of retail outlets where this is more likely to occur.

METHODS

Questions on cigarette purchasing were added to a post-campaign telephone survey for the Make Smoking History Campaign in Western Australia. Respondents (n=200) were aged 25 to 54 years and were either current smokers or had quit in the last 4-5 weeks. Two-thirds of respondents had tried to quit in the past 2 years. Survey responses were analysed to look at place of purchase (the usual and after cessation relapse) and frequency and reasons for unplanned purchases.

RESULTS

Supermarkets were the "usual" purchase location for the majority of respondents overall (78%), but the proportion who reported buying cigarettes from a supermarket after taking up smoking again declined substantially (52%), while purchases from convenience stores and service stations increased. Nearly a third (30%) of respondents indicated that they sometimes bought cigarettes unplanned or on impulse, and for 16%, this was at least once a week.

CONCLUSIONS

Among smokers who have tried to quit but not succeeded, unplanned cigarette purchases are common. There is evidence to suggest that when people resume smoking after a cessation attempt, the cigarette purchase is not necessarily made at their "usual" type of retail outlet. SO WHAT?: The banning of point of sale tobacco display has not eliminated the pervasive availability and retail presence of tobacco, and unplanned purchasing of cigarettes is an impediment to successful smoking cessation. This study adds weight to growing momentum internationally and in Australia to reduce the widespread availability of tobacco products and decrease the barriers to quitting use of a product that kills over half of its consumers.

Impact of tobacco control policies on smoking prevalence and quit ratios in 27 European Union countries from 2006 to 2014

BACKGROUND

Tobacco use is still highly prevalent in Europe, despite the tobacco control efforts made by the governments. The development of tobacco control policies varies substantially across countries. The Tobacco Control Scale (TCS) was introduced to quantify the implementation of tobacco control policies across European countries OBJECTIVE: To assess the midterm association of tobacco control policies on smoking prevalence and quit ratios among 27 European Union (EU) Member States (EU27).

METHODS

Ecological study. We used the TCS in EU27 in 2007 and the prevalence of tobacco and quit ratios data from the Eurobarometer survey (2006 (n=27 585) and 2014 (n=26 793)). We analysed the relationship between the TCS scores and smoking prevalence and quit ratios and their relative changes (between 2006 and 2014) by means of scatter plots and multiple linear regression models.

RESULTS

In EU27, countries with higher scores in the TCS, which indicates higher tobacco control efforts, have lower prevalence of smokers, higher quit ratios and higher relative decreases in their prevalence rates of smokers over the last decade. The correlation between TCS scores and smoking prevalence (rsp=-0.444; P=0.02) and between the relative changes in smoking prevalence (rsp=-0.415; P=0.03) was negative. A positive correlation was observed between TCS scores and quit ratios (rsp=0.373; P=0.06). The percentage of smoking prevalence explained by all TCS components was 28.9%.

CONCLUSION

EU27 should continue implementing comprehensive tobacco control policies as they are key for reducing the prevalence of smoking and an increase tobacco cessation rates in their population.

Cost-effectiveness of increasing the reach of smoking cessation interventions in Germany: results from the EQUIPTMOD

AIMS

To evaluate costs, effects and cost-effectiveness of increased reach of specific smoking cessation interventions in Germany.

DESIGN

A Markov-based state transition return on investment model (EQUIPTMOD) was used to evaluate current smoking cessation interventions as well as two prospective investment scenarios. A health-care perspective (extended to include out-of-pocket payments) with life-time horizon was considered. A probabilistic analysis was used to assess uncertainty concerning predicted estimates.

SETTING

Germany.

PARTICIPANTS

Cohort of current smoking population (18+ years) in Germany.

INTERVENTIONS

Interventions included group-based behavioural support, financial incentive programmes and varenicline. For prospective scenario 1 the reach of group-based behavioral support, financial incentive programme and varenicline was increased by 1% of yearly quit attempts (= 57 915 quit attempts), while prospective scenario 2 represented a higher reach, mirroring the levels observed in England.

MEASUREMENTS

EQUIPTMOD considered reach, intervention cost, number of quitters, quality-of-life years (QALYs) gained, cost-effectiveness and return on investment.

FINDINGS

The highest returns through reduction in smoking-related health-care costs were seen for the financial incentive programme (€2.71 per €1 invested), followed by that of group-based behavioural support (€1.63 per €1 invested), compared with no interventions. Varenicline had lower returns (€1.02 per €1 invested) than the other two interventions. At the population level, prospective scenario 1 led to 15 034 QALYs gained and €27 million cost-savings, compared with current investment. Intervention effects and reach contributed most to the uncertainty around the return-on-investment estimates. At a hypothetical willingness-to-pay threshold of only €5000, the probability of being cost-effective is approximately 75% for prospective scenario 1.

CONCLUSIONS

Increasing the reach of group-based behavioural support, financial incentives and varenicline for smoking cessation by just 1% of current annual quit attempts provides a strategy to German policymakers that improves the population's health outcomes and that may be considered cost-effective.

Predictors of Continued Smoking and Interest in Cessation Among Older Female Smokers

OBJECTIVES

Older female smokers are highly vulnerable, yet little is known about their attitudes, beliefs, and behaviors regarding smoking cessation.

METHODS

Southeast region Women's Health Initiative participants identified as smokers on at least one prior assessment were surveyed in 2012 regarding current tobacco use.

RESULTS

Most of these current and former smokers ( N = 409, 63% response) were non-Hispanic White (81.7%) and had some college (80%), with mean age of 75.1 years. Current smoking was confirmed by 56%, and while 61% of these reported a past-year quit attempt, less than half used quit aids. Of current smokers, 57.5% intended to quit within 6 months (26.6% within 30 days), and 68% were interested in joining a cessation study.

CONCLUSIONS

Older female smokers were highly motivated to quit, yet profoundly underutilized proven quit aids. Results support high acceptability of cessation interventions for this undertreated population.

Smoking behavior of males attending the quit tobacco clinics in Bahrain and their knowledge on tobacco smoking health hazards

Background

One third of Bahraini adult (20–64 years) males and 7.0% of females use some form of tobacco. The corresponding rates for cigarette and waterpipe tobacco smoking (WTS) are 11.0% and 6.0%, respectively. The objective of the study was to determine the knowledge on tobacco smoking and past smoking related behavior of male patients attending the Quit Tobacco Clinics (QTC) in Bahrain.

Methods

A sample of 339 male clinic attendees was taken proportional to the population distribution in the three QTC at Al Hoora Health Center, Hamad Kanoo Health Center, and Bank of Bahrain and Kuwait Health Center. Data collection was performed until the sample size was completed (September 2015 to December 2016). Knowledge on the health effects of cigarette and WTS was examined based on 10 statements on cigarette and similar ones on WTS. Respondents “agreeing” with the statements were considered knowledgeable and those “disagreeing” or responding “don’t know”, not knowledgeable. All the “agree” responses for cigarette/WTS were summed across the 10 health effects and average health knowledge scores for cigarette/WTS were computed.

Results

Most of the study participants were Bahraini nationals, ever married and educated with at least secondary level. The majority (65.8%) of participants smoked a single type of tobacco product, and the rest, two (28.0%) or three or more (6.2%). Age of starting cigarette and WTS was 16.2 ± 4.0 and 19.3 ± 6.7 years, respectively. The majority (81%) smoked in the presence of other family members and 26.3% in the presence of a child. 76.2% smoked in the presence of others in their cars. 18.9% of the attendees had quit smoking at the time of interview. 81% of the participants knew about the hazards of both cigarette and WTS with a significantly higher (p = 0.0001) mean knowledge score for cigarette (93.3 ± 3.0%) than WTS (85.2 ± 2.1%).

Conclusion

The relative lack of knowledge on the hazards of WTS in a sample of Arab country population with an increasing trend of WTS warrants the attention of health policy makers in the country and region.

Unaided Smoking Cessation in Healthy Employees

BACKGROUND

According to guidelines, behavioral and pharmacological assistance should be offered to all smokers willing to quit. However, a large proportion of ex-cigarette smokers are self-quitters.

OBJECTIVES

To identify characteristics of long-term, unaided self-quitters, as compared to recurrent smokers among health care employees.

METHODS

University hospital employees (n = 5,218) were addressed through a 17-question questionnaire inquiring about past and current smoking behavior. Questions included daily cigarette consumption, pack-years, previous quit attempts, smoking-free period, and utilization of pharmacological therapies and counseling.

RESULTS

2,574 (49.3%) questionnaires were returned. 791 subjects declared to have successfully quit smoking. A complete data set was available for 763 cases. Patients remained smoking free for a mean period of 11.8 ± 9.7 years. The most common smoking cessation method in these subjects was unaided (77.2%), followed by alternative approaches (15.4%), nicotine replacement therapy (4.5%), counseling (1.7%), and bupropion (1.2%). Smoking cessation was achieved with 1 attempt in 53% of the cases, 2 in 19%, 3 in 13%, and more than 3 attempts in 15%, respectively. On average, 2.4 ± 3.02 attempts led to successful smoking cessation. After 2 or more unsuccessful attempts, the odds ratio for a further unsuccessful smoking cessation was 2.58 (95% CI 1.94-3.45).

CONCLUSION

The majority of the ex-smokers quitted smoking without any behavioral or pharmacological support. The chance to successfully quit smoking without any help in a first or second attempt is considerably high. The risk for smoking recurrence after 2 ineffective quit attempts is markedly increased (OR 2.58).

Participant-level meta-analysis of mobile phone-based interventions for smoking cessation across different countries

With meta-analysis, participant-level data from five text messaging-based smoking cessation intervention studies were pooled to investigate cessation patterns across studies and participants. Individual participant data (N=8315) collected in New Zealand (2001-2003; n=1705), U.K. (2008-2009; n=5792), U.S. (2012; n=503; n=164) and Turkey (2012; n=151) were collectively analyzed in 2014. The primary outcome was self-reported 7-day continuous abstinence at 4weeks post-quit day. Secondary outcomes were: (1) self-reported 7-day continuous abstinence at 3months and (2) self-reported continuous abstinence at 6months post-quit day. Generalized linear mixed models were fit to estimate the overall treatment effect, while accounting for clustering within individual studies. Estimates were adjusted for age, sex, socioeconomic status, previous quit attempts, and baseline Fagerstrom score. Analyses were intention to treat. Participants lost to follow-up were treated as smokers. Twenty-nine percent of intervention participants and 12% of control participants quit smoking at 4weeks (adjusted odds ratio [aOR]=2.89, 95% CI [2.57, 3.26], p<.0001). An attenuated but significant effect for cessation for those in the intervention versus control groups was observed at 3months (aOR=1.88, 95% CI [1.53, 2.31]) and 6months (aOR=2.24, 95% CI [1.90, 2.64]). Subgroup analyses were conducted but few significant findings were noted. Text messaging-based smoking cessation programs increase self-reported quitting rates across a diversity of countries and cultures. Efforts to expand these low-cost and scalable programs, along with ongoing evaluation, appear warranted.

Effect of Tobacco Control Policies on Information Seeking for Smoking Cessation in the Netherlands: A Google Trends Study

Background

The impact of tobacco control policies on measures of smoking cessation behaviour has often been studied, yet there is little information on their precise magnitude and duration. This study aims to measure the magnitude and timing of the impact of Dutch tobacco control policies on the rate of searching for information on smoking cessation, using Google Trends search query data.

Methods

An interrupted time series analysis was used to examine the effect of two types of policies (smoke-free legislation and reimbursement of smoking cessation support (SCS)) on Google searches for ‘quit smoking’. Google Trends data were seasonally adjusted and analysed using autoregressive integrated moving average (ARIMA) modelling. Multiple effect periods were modelled as dummy variables and analysed simultaneously to examine the magnitude and duration of the effect of each intervention. The same analysis was repeated with Belgian search query data as a control group, since Belgium is the country most comparable to the Netherlands in terms of geography, language, history and culture.

Results

A significant increase in relative search volume (RSV) was found from one to four weeks (21–41%) after the introduction of the smoking ban in restaurants and bars in the Netherlands in 2008. The introduction of SCS reimbursement in 2011 was associated with a significant increase of RSV (16–22%) in the Netherlands after 3 to 52 weeks. The reintroduction of SCS in 2013 was associated with a significant increase of RSV (9–21%) in the Netherlands from 3 to 32 weeks after the intervention. No effects were found in the Belgian control group for the smoking ban and the reintroduction of SCS in 2013, but there was a significant increase in RSV shortly before and after the introduction of SCS in 2011.

Conclusions

These findings suggest that these tobacco control policies have short-term or medium-term effects on the rate of searching for information on smoking cessation, and therefore potentially on smoking cessation rates.

Smoking determines the 10-year (2004-2014) prognosis in patients with Acute Coronary Syndrome: the GREECS observational study

Background

Smoking has long been positively associated with the development and progression of coronary heart disease. However, longitudinal cohort studies evaluating smoking habits among cardiac patients as well as the role of socio-demographic factors determining such behaviours are scarce and have been focused on primary care practice. Thus the aim of the present work was to examine the association of active smoking and behaviours and exposure to second-hand smoke, with the 10-year Acute Coronary Syndrome (ACS) prognosis, among cardiovascular patients.

Methods

From October 2003 to September 2004, a sample of six Greek hospitals was selected and almost allconsecutive 2172 ACS patients were enrolled. In 2013–14, the 10-year follow-up was performed in 1918 participants (11 % loss to follow-up). Smoking habits at the time of entry to the study, as well as during the follow-up period were studied using a standard questionnaire.

Results

Patients who had >60 pack-years of smoking had 57.8 % higher ACS mortality and 24.6 % higher risk for any ACS event. Nested model, adjusted only for age and sex, revealed that for every 30 pack-years of smoking increase, the associated ACS risk increased by 13 % (95 % CI 1.03, 1.30, p = 0.001). When further adjusted analysis, including several potential confounders, was applied the tested relationship was still significant (95 %CI 1.03, 1.30, p = 0.09). Accordingly, the risk for fatal ACS events increased by 8 % for every 30 pack-years of smoking increase (95 % CI 1.03, 1.63, p = 0.06). Moreover, 52 % of the patients reported being exposed to secondhand smoke and when further adjustments were made, it was revealed that they had 33 % (95 % CI 1.12, 1.60, p = 0.01) higher risk of having recurrent ACS events.

Conclusions

Active smoking and second-hand smoke among cardiac patients still represent a substantial clinical burden. Thus, smoking cessation policies should be incorporated into the long-term therapeutic management.

Changes in the Prevalence of Tobacco Consumption and the Profile of Spanish Smokers after a Comprehensive Smoke-Free Policy

BACKGROUND

A partial smoke-free regulation in Spain was introduced on January 1, 2006, which was subsequently amended to introduce a comprehensive smoke-free policy from 2 January 2011 onward. The objective of this study was to compare the prevalence of tobacco consumption in Spain and the profile of smokers before (2006) and after (2011) the comprehensive smoking ban passed in 2010.

METHODS

Two independent, cross-sectional, population-based surveys were carried out among the adult (≥ 18 years old) Spanish population in 2006 and 2011 through telephone interviews. Both surveys used the same methods and questionnaire. Nicotine dependence was assessed with the Fagerström Test for nicotine dependence and readiness to quit according to the stages of change.

RESULTS

The prevalence of tobacco consumption showed a nonsignificant decrease from 23.4% in 2006 to 20.7% in 2011. No changes were observed in nicotine dependence or readiness to quit. In 2011, most smokers (76%) showed low nicotine dependence and were mainly in the precontemplation stage (72%).

CONCLUSIONS

The prevalence of smokers has slightly decreased since the introduction of the total smoking ban in Spain. No differences were found in nicotine dependence or readiness to quit.

Implementation and effectiveness of a hospital smoking cessation service in Germany

OBJECTIVE

Hospitalized smokers are often highly motivated to quit and receptive to assistance. There are few published accounts of hospital-based smoking cessation programmes implemented outside of a trial setting, particularly outside North America. We describe the implementation and effectiveness of a dedicated smoking cessation service in Freiburg, Germany.

METHODS

Measures of implementation (e.g. number of patients referred and consenting to participate, receipt of post-discharge support) and effectiveness are presented.

RESULTS

In the first 2 years of the service, 1432 patients were referred. Over half (55.3%) of counselled smokers agreed to participate. Sustained abstinence for 6 months was achieved by 28.0% (missing cases coded as smokers), whereas 7-day point prevalence rates were between 30 and 35% at 3, 6 and 12 months. Those who received 4+ post-discharge calls were more likely to achieve sustained abstinence, as were older smokers, those with higher self-efficacy, and cardiovascular patients.

CONCLUSION

Hospitalized patients in Germany are receptive to the offer of bedside counselling and to phone support post-discharge, and success rates are comparable to those achieved in other countries.

PRACTICE IMPLICATIONS

The findings argue strongly for the routine identification of smokers upon hospital admission, and the availability of cessation support both during hospitalization and following discharge.

Just blowing smoke? Social desirability and reporting of intentions to quit smoking

INTRODUCTION

Do cigarette smokers really want to quit smoking or do they simply say they do in order to placate others and avoid criticism? In surveys of smokers, stated quit intentions and reports of quit attempts may be biased by social desirability concerns. This makes it difficult to interpret large-scale state and national surveys of smoking behavior that collect data through telephone and face-to-face interviews, methods that tend to evoke high levels of socially desirable responding.

METHODS

The 2007 Health Information National Trends Survey used a dual-frame design to query smokers' quit intentions and past quit attempts in 1 of 2 ways: A self-administered mail survey (low pressure for socially desirable responding; n = 563), or an interviewer-administered telephone survey (high pressure for socially desirable responding; n = 499). Estimates derived from the 2 formats were compared to test for social desirability effects.

RESULTS

In both survey modes, approximately two thirds of smokers reported seriously considering quitting in the next 6 months (mail: 64.9%; telephone: 68.9%), and approximately half reported making a quit attempt in the past year (mail: 54.9%; telephone: 52.3%). Neither difference approached significance in logistic regressions controlling for demographics (ps > .24).

CONCLUSIONS

It appears that a large proportion of smokers in the United States aspire to live smoke-free lives and are not simply responding in a socially desirable manner to deflect criticism in an antismoking social climate. Future research should (1) replicate this study with greater statistical power, (2) examine the possible effects of survey context (e.g., health survey vs. smoking pleasure survey), and (3) explore survey mode effects in specific subpopulations.

German medical students' beliefs about the effectiveness of different methods of stopping smoking

INTRODUCTION

In many countries, smoking cessation interventions are not routinely delivered as recommended in national and international guidelines. This may be because of incorrect beliefs about their effectiveness. This study assessed which cessation methods are believed to be effective by medical students in different years of undergraduate education as well as predictors of correct beliefs about effectiveness.

METHODS

In this cross-sectional study, undergraduate students from 27 German medical schools were invited to complete a survey addressing demographic characteristics, smoking status, self-rated knowledge of health consequences, and treatment options for smoking and beliefs about the effectiveness of 8 different methods to achieve long-term smoking cessation. Predictors of beliefs were identified by means of multilevel modeling.

RESULTS

A total of 19,526 students completed the survey. Students greatly overestimated the effectiveness of unaided quitting, and differences between years of undergraduate education were small. In the final year, 51% of students wrongly believed that willpower alone was more effective than a comprehensive group cessation program, including nicotine replacement therapy. Multilevel modeling revealed that having never smoked, supporting public smoking bans, and recalling theoretical training in smoking cessation were associated with correct beliefs.

CONCLUSIONS

A considerable proportion of German medical students believe that willpower alone is more effective than comprehensive treatment programs to support a quit attempt.

Variant within the promoter region of the CHRNA3 gene associated with FTN dependence is not related to self-reported willingness to quit smoking

INTRODUCTION

Common variation in the CHRNA5-CHRNA3-CHRNB4 gene region is robustly associated with smoking quantity. Conversely, the association between one of the most significant single nucleotide polymorphisms (SNPs; rs1051730 within the CHRNA3 gene) with perceived difficulty or willingness to quit smoking among current smokers is unknown.

METHODS

Cross-sectional study including current smokers, 502 women, and 552 men. Heaviness of smoking index (HSI), difficulty, attempting, and intention to quit smoking were assessed by questionnaire.

RESULTS

The rs1051730 SNP was associated with increased HSI (age, gender, and education-adjusted mean ± SE: 2.6 ± 0.1, 2.2 ± 0.1, and 2.0 ± 0.1 for AA, AG, and GG genotypes, respectively, p < .01). Multivariate logistic regression adjusting for gender, age, education, leisure-time physical activity, and personal history of cardiovascular or lung disease showed rs1051730 to be associated with higher smoking dependence (odds ratio [OR] and 95% CI for each additional A-allele: 1.38 [1.11-1.72] for smoking more than 20 cigarette equivalents/day; 1.31 [1.00-1.71] for an HSI ≥5 and 1.32 [1.05-1.65] for smoking 5 min after waking up) and borderline associated with difficulty to quit (OR = 1.29 [0.98-1.70]), but this relationship was no longer significant after adjusting for nicotine dependence. Also, no relationship was found with willingness (OR = 1.03 [0.85-1.26]), attempt (OR = 1.00 [0.83-1.20]), or preparation (OR = 0.95 [0.38-2.38]) to quit. Similar findings were obtained for other SNPs, but their effect on nicotine dependence was no longer significant after adjusting for rs1051730.

CONCLUSIONS

These data confirm the effect of rs1051730 on nicotine dependence but failed to find any relationship with difficulty, willingness, and motivation to quit.

Prevalence and factors associated with difficulty and intention to quit smoking in Switzerland

BACKGROUND

Recent data indicate a slight decrease in the prevalence of smoking in Switzerland, but little is known regarding the intention and difficulty to quit smoking among current smokers. Hence, we aimed to quantify the difficulty and intention to quit smoking among current smokers in Switzerland.

METHODS

Cross-sectional study including 607 female and 658 male smokers. Difficulty, intention and motivation to quit smoking were assessed by questionnaire.

RESULTS

90% of women and 85% of men reported being "very difficult" or "difficult" to quit smoking. Almost three quarters of smokers (73% of women and 71% of men) intended to quit; however, less than 20% of them were in the preparation stage and 40% were in the precontemplation stage. On multivariate analysis, difficulty to quit was lower among men (Odds ratio and 95% [confidence interval]: 0.51 [0.35-0.74]) and increased with nicotine dependence and number of previous quitting attempts (OR=3.14 [1.75-5.63] for 6+ attempts compared to none). Intention to quit decreased with increasing age (OR=0.48 [0.30-0.75] for ≥65 years compared to <45 years) and increased with nicotine dependence, the number of previous quitting attempts (OR=4.35 [2.76-6.83] for 6+ attempts compared to none) and among non-cigarette smokers (OR=0.51 [0.28-0.92]). Motivation to quit was inversely associated with nicotine dependence and positively associated with the number of previous quitting attempts and personal history of lung disease.

CONCLUSION

Over two thirds of Swiss smokers want to quit. However, only a small fraction wishes to do so in the short term. Nicotine dependence, previous attempts to quit or previous history of lung disease are independently associated with difficulty and intention to quit.

Individual and family factors associated with intention to quit among male Vietnamese American smokers: implications for intervention development

Smoking prevalence among Vietnamese American males remains higher than the U.S. general population. This study examined the associations of individual and family factors with quit intention among Vietnamese male smokers in California to guide intervention development to reduce their smoking prevalence. Data for Vietnamese male current smokers (n=234) in the 2008 California Vietnamese Adult Tobacco Use Survey (N=1101 males) were analyzed to describe quit intention and previous quit attempts. One-third of Vietnamese male smokers (33%) had no intention to quit at any time, 36% intended to quit soon (in the next 30 days), and 31% intended to quit later (beyond the next 30 days). Half (51.7%) of the sample was in "precontemplation," indicating no intention to quit within 6 months. Many (71%) had made a serious quit attempt in the past year, but 68% of those who tried to quit used no cessation assistance. Multivariate logistic regression adjusting for age, depression, smoking intensity, nicotine dependence, health knowledge, children in the household and home smoking ban revealed that having smoking-related family conflicts and a quit attempt in the past year with or without assistance were independently associated with an intention to quit either in the next 30 days or later. Higher education was associated with no intention to quit. Findings underscore the importance of designing strategic interventions that meet the needs of smokers at both individual and family levels to promote quit intention and to facilitate successful quitting in this population.

Smoking behaviour, involuntary smoking, attitudes towards smoke-free legislations, and tobacco control activities in the European Union

Background

The six most important cost-effective policies on tobacco control can be measured by the Tobacco Control Scale (TCS). The objective of our study was to describe the correlation between the TCS and smoking prevalence, self-reported exposure to secondhand smoke (SHS) and attitudes towards smoking restrictions in the 27 countries of the European Union (EU27).

Methods/Principal Findings

Ecologic study in the EU27. We used data from the TCS in 2007 and from the Eurobarometer on Tobacco Survey in 2008. We analysed the relations between the TCS and prevalence of smoking, self-reported exposure to SHS (home and work), and attitudes towards smoking bans by means of scatter plots and Spearman rank-correlation coefficients (r_sp). Among the EU27, smoking prevalence varied from 22.6% in Slovenia to 42.1% in Greece. Austria was the country with the lowest TCS score (35) and the UK had the highest one (93). The correlation between smoking prevalence and TCS score was negative (r_sp = −0.42, p = 0.03) and the correlation between TCS score and support to smoking bans in all workplaces was positive (r_sp = 0.47, p = 0.01 in restaurants; r_sp = 0.5, p = 0.008 in bars, pubs, and clubs; and r_sp = 0.31, p = 0.12 in other indoor workplaces). The correlation between TCS score and self-reported exposure to SHS was negative, but statistically non-significant.

Conclusions/Significance

Countries with a higher score in the TCS have higher support towards smoking bans in all workplaces (including restaurants, bars, pubs and clubs, and other indoor workplaces). TCS scores were strongly, but not statistically, associated with a lower prevalence of smokers and a lower self-reported exposure to SHS.

Effect of smoking cessation intervention on results of acute fracture surgery: a randomized controlled trial

BACKGROUND

Tobacco smoking is a major health and economic concern and is also known to have a significant negative effect on surgical outcomes. The benefits of a smoking cessation intervention prior to elective orthopaedic surgery have been evaluated previously. Our aim was to assess whether a smoking cessation program, initiated during the acute hospitalization period and carried out for six weeks, could reduce the number of complications following emergency surgical treatment of fractures.

METHODS

In a multicenter, single-blinded, randomized, controlled clinical trial, 105 smokers with a fracture of the lower or upper extremity that needed acute surgical treatment were randomized to an intervention group (n = 50) or a control group (n = 55). The intervention group was offered a standardized smoking cessation program for six weeks, and all patients were followed at two to three weeks, four weeks, and six to twelve weeks.

RESULTS

The proportion of patients with at least one postoperative complication was significantly larger in the control group than it was in the intervention group (38% and 20%, respectively; p = 0.048). The development of two or more postoperative complications was also more common among the controls (p = 0.039). The rates of superficial wound infection, the most frequently recorded complication in both groups, were 20% and 8%, but this difference was not significant. A secondary analysis showed that the odds of having a complication were 2.51 times (95% confidence interval, 0.96 to 6.9 times) higher in the control group than in the intervention group, but this difference was not significant.

CONCLUSIONS

Our results indicate that a smoking cessation intervention program during the first six weeks after acute fracture surgery decreases the risk of postoperative complications.

The French Observational Cohort of Usual Smokers (FOCUS) cohort: French smokers perceptions and attitudes towards smoking cessation

BACKGROUND

Despite increasing governmental anti-smoking measures, smoking prevalence remains at a high level in France.

METHODS

The objectives of this panel study were (1) to estimate smoking prevalence in France, (2) to identify smokers' profiles according to their perceptions, attitudes and behaviour in relation to smoking cessation, (3) to determine predictive factors of quit attempts, and (4) to assess tobacco-related behaviours and their evolutions according to the changes in the smokers' environments. A representative sample of French population was defined using the quota method. The identified cohort of smokers was assessed, in terms of smoking behaviour, previous quit attempts, and intention to quit smoking.

RESULTS

A response rate of 66% for the screening enabled to identify a representative sample of the French population (N = 3 889) comprising 809 current smokers (21%). A majority of current smokers (63%) had made an attempt to quit smoking. Main reasons for having made the last attempt were cost (44%), social pressure (39%), wish to improve physical fitness (36%), fear of a future smoking-related disease (24%), and weariness of smoking (21%). Few attempts (16%) were encouraged by a physician. In those who used some kind of support (38%), NRT was the mostly used. Relapse was triggered by craving (45%), anxiety/stress (34%), a significant life event (21), weight gain (18%), and irritability (16%). Depression was rarely quoted (5%). Forty percent of smokers declared they intended to quit smoking permanently. Main reasons were cost (65%), physical fitness improvement (53%), fear of a future smoking-related disease (43%), weariness of tobacco (34%), and social pressure (30%). Using a smoking cessation treatment was considered by 43% of smokers that intended to quit. Barriers to smoking cessation were mainly fear of increased stress (62%), irritability (51%), and anxiety (42%), enjoying smoking (41%), and weight concerns (33%).

CONCLUSION

Smoking prevalence and smoking cessation attempts rate were lower in this survey than in previous reports. Cost and social pressure were the main reasons for quitting smoking, maybe an effect of dramatic tax increases and smoking ban.

Should we change the focus of health promotion in sexual health clinics?

The effectiveness of sexual behaviour change interventions in sexual health clinics is unknown. Risk factors for poor sexual and reproductive health such as depression, violence, alcohol and smoking in sexual health clinics are all common and can be identified easily in sexual health services. Targeting these risk factors could be as effective as traditional sexual health promotion and could have additional benefits. The authors propose a pilot to assess the cost-effectiveness and acceptability of incorporating screening and interventions for these risk factors.

Cigarette smoking among university students in Greece: a comparison between medical and other students

OBJECTIVES

The purpose of the study was to investigate the smoking habits of medical and other students and to explore the most important factors associated with students' smoking.

METHODS

University students were surveyed in late spring 2006 regarding their smoking status and additional health- and behavior-related characteristics.

RESULTS

A total of 1205 (269 medical and 936 nonmedical) students participated in the study. Of these 47% reported being current smokers (35% among medical students), and 30% of the smokers had already started smoking at the age of 16 years. Smokers reported a significantly higher prevalence of cough and respiratory infections and a decrease in physical fitness. The most important factor associated with smoking prevalence was friendship with smokers and maternal smoking. A better knowledge of harmful effects showed a strong association with nonsmokers. Although nonmedical students exhibited a greater possibility to be a smoker, awareness of harmful effects among medical students was not as significant as factor against smoking compared with among nonmedical students.

CONCLUSIONS

This study shows that smoking prevalence among medical and other students in Greece is extremely high. A lack of effective education against smoking in medical students was evident and this underlines the need to identify the factors to be included in planning effective antismoking programs.

Mortality after First Myocardial Infarction in Greek Patients: A 4-Year Follow-Up Study

Background

Death associated with coronary heart disease (CHD) depends in part on the time since the myocardial infarction (MI) and modification of risk factors.

Methods

This observational, retrospective 4-year follow-up study consisted of 804 patients (628 men). The participants completed a questionnaire reporting diet, demographic factors, personal behavior (smoking, physical activity), anthropometry, prior medical conditions (hypertension, diabetes mellitus), and recent medication.

Results

During 48 months of follow-up, 12% of men and 15% of women died. Older age, longer duration of smoking, and frequency of exercise were significantly different between survivors and the deceased ( P = .014, P = .014, P = .001, respectively). Multivariate analysis revealed associations with years of smoking (odds ratio, OR: 1.10, P = .025), treatment with nitrates (OR: 4.81, P = .024), and increased frequency of exercise (OR: 0.42, P = .013), adjusting for age and gender.

Conclusions

We should emphasize cessation of smoking and increased physical activity in MI survivors. Antismoking programs should start at an early age.
