Effect of quitting immediately vs progressively on smoking cessation for smokers at emergency department in Hong Kong: A posteriori analysis of a randomized controlled trial

BACKGROUND

A progressive approach to quitting smoking has been a popular strategy for motivating smokers who are reluctant to quit. However, whether this strategy can effectively achieve complete cessation or is as successful as quitting immediately remains unresolved. This study aimed to determine whether quitting immediately or progressively was more effective in achieving complete cessation among smokers in Hong Kong who presented at emergency departments.

METHODS AND FINDINGS

A posteriori analysis of a single-blinded, multicenter, randomized controlled trial was performed. The original trials was conducted at emergency departments of four major acute hospitals in different districts of Hong Kong. In total, 1571 smokers 18 years or older who presented at 4 major emergency departments between July 4, 2015 and March 17, 2017 were randomized into an intervention group (n = 787) and a control group (n = 784). The intervention group received brief advice (about 1 minute) and could choose their own quit schedules (immediate or progressive, labeled QI and QP, respectively). The control group received a smoking cessation leaflet. Follow-ups were conducted at 1, 3, 6 and 12 months. The primary outcomes, by intention-to-treat, were biochemically validated abstinence between the QI subgroup and control group; between the QP subgroup and control group, and between the QI subgroup and QP subgroup at 6 months. After the propensity sore matching, the biochemically validated abstinence was statistically significantly higher in the QI subgroup than the control group at 6 months (12.1% vs 3.4%, P = 0.003; adjusted odds ratio [aOR] 4.34, 95% CI 1.63-11.52) and higher in the QP subgroup than the control group at 6 months (9.8% vs 3.4%, P = 0.02; aORs 2.95, 95% CI: 1.04-8.39). No statistically significant differences of biochemically validated abstinence at both 6 month (12.1% vs 9.8%, P = 0.49; aORs 1.50, 95% CI: 0.71-3.19) were found in the comparison between QI and QP subgroups.

CONCLUSIONS

This study demonstrates that the strategy of quitting progressively is effective, especially for smokers who lack motivation or find it difficult to quit. If adopted routinely, such an approach can help achieve a greater level of smoking abstinence in the community.

Physical Activity Promotion and the United Nations Sustainable Development Goals: Building Synergies to Maximize Impact

BACKGROUND

Many of the known solutions to the physical inactivity pandemic operate across sectors relevant to the United Nations Sustainable Development Goals (SDGs).

METHODS

The authors examined the contribution of physical activity promotion strategies toward achieving the SDGs through a conceptual linkage exercise, a scoping review, and an agent-based model.

RESULTS

Possible benefits of physical activity promotion were identified for 15 of the 17 SDGs, with more robust evidence supporting benefits for SDGs 3 (good health and well-being), 9 (industry, innovation, and infrastructure), 11 (sustainable cities and communities), 13 (climate action), and 16 (peace, justice, and strong institutions). Current evidence supports prioritizing at-scale physical activity-promoting transport and urban design strategies and community-based programs. Expected physical activity gains are greater for low-and middle-income countries. In high-income countries with high car dependency, physical activity promotion strategies may help reduce air pollution and traffic-related deaths, but shifts toward more active forms of travel and recreation, and climate change mitigation, may require complementary policies that disincentivize driving.

CONCLUSIONS

The authors call for a synergistic approach to physical activity promotion and SDG achievement, involving multiple sectors beyond health around their goals and values, using physical activity promotion as a lever for a healthier planet.

A Magic Bullet? The Potential Impact of E-Cigarettes on the Toll of Cigarette Smoking

INTRODUCTION

We examine the proportion of US smoking-produced mortality that e-cigarettes might eliminate under assumptions regarding vaping's ability to increase smoking cessation, vaping's health risks, and the possibility that vaping will increase smoking among young people.

METHODS

We employ a dynamic population simulation model that tracks individuals from ages 0 to 110, differentiated by gender and smoking status. Using data from the US Census, the National Vital Statistics Reports, Cancer Prevention Study II, and the National Health Interview Survey, we estimate the number of smoking-related life-years lost (LYL) from 2018 to 2100 in a no-vaping scenario. We then compare results for model runs that assess the impact of vaping under a variety of assumptions.

RESULTS

The combination of assumptions produces 360 possible scenarios. 357 (99%) yield positive estimates of life-years saved (LYS) due to vaping by 2100, from 143 000 to 65 million. Most scenarios result in millions of individuals quitting smoking due to vaping. On average, vaping-induced quitters gain an extra 1.2-2.0 years of life compared to smokers who quit without vaping. The impact of vaping is greatest when it most helps smokers who otherwise have the greatest difficulty quitting smoking. While the numbers of LYS are generally large across all scenarios, they often represent a small fraction of the toll of smoking.

CONCLUSIONS

Vaping is highly likely to reduce smoking-produced mortality. Still, vaping is not "the" answer to the public health crisis created by smoking. Rather, it may well be a tool to add to the armamentarium of effective tobacco control measures.

IMPLICATIONS

E-cigarettes hold the potential to reduce cigarette smoking's enormous toll. By itself, however, tobacco harm reduction, as embodied in vaping, is no magic bullet. Going forward, tobacco control will require vigilant application of the evidence-based measures that have brought us so much success in combatting smoking. It will require, as well, the search for and adoption of novel means of attacking the remaining problem. Harm reduction can, and many would say should, be a part of the complex formula that will eventually bring about the demise of smoking.

Sex differences in nicotine-induced impulsivity and its reversal with bupropion in rats

BACKGROUND

Enhancement in cognitive impulsivity and the resulting alterations in decision making serve as a contributing factor for the development and maintenance of substance-use disorders. Nicotine-induced increases in impulsivity has been previously reported in male humans and rodents. Although the potential for sex differences in nicotine-induced impulsivity has not been examined.

AIMS AND METHODS

In the present study, male and female Sprague Dawley rats were submitted to a delay discounting task, in which several consecutive measures of self-control were taken. Firstly, rats were tested with vehicle, and next with nicotine doses of 0.4 and 0.8 mg/kg. Thereafter, chronic treatment with bupropion started, and the animals were tested again. Half the animals continued to receive 0.8 mg/kg of nicotine, while the rest received nicotine and also a daily dose of 30 mg/kg of bupropion.

RESULTS

When the animals were first tested with nicotine, female rats showed a significant nicotine dose dependent increase of impulsive behaviour, whereas male rats only showed a decrease on their elections of the larger but delayed reward under the highest dose of 0.8 mg/kg of nicotine. Treatment with bupropion blocked the effect of nicotine on decision making in female rats, as they showed results close to their baseline levels. On the other hand, bupropion did not affect the nicotine-induced delay discounting in male rats.

CONCLUSION

These findings demonstrate sexually dimorphic effects of nicotine on cognitive impulsivity which may help to shed light on nicotine use vulnerabilities observed in women.

The 20-year impact of tobacco price and tobacco control expenditure increases in Minnesota, 1998-2017

Introduction

Tobacco control programs and policies reduce tobacco use and prevent health and economic harms. The majority of tobacco control programs and policies in the United States are implemented at local and state levels. Yet the literature on state-level initiatives reports a limited set of outcomes. To facilitate decision-making that is increasingly focused on costs, we provide estimates of a broader set of measures of the impact of tobacco control policy, including smoking prevalence, disease events, deaths, medical costs, productivity and tobacco tax revenues, using the experience of Minnesota as an example.

Methods

Using the HealthPartners Institute’s ModelHealth^™: Tobacco MN microsimulation, we assessed the impact of the stream of tobacco control expenditures and cigarette price increases from 1998 to 2017. We simulated 1.3 million individuals representative of the Minnesota population.

Results

The simulation estimated that increased expenditures on tobacco control above 1997 levels prevented 38,400 cancer, cardiovascular, diabetes and respiratory disease events and 4,100 deaths over 20 years. Increased prices prevented 14,600 additional events and 1,700 additional deaths. Both the net increase in tax revenues and the reduction in medical costs were greater than the additional investments in tobacco control.

Conclusion

Combined, the policies address both short-term and long-term goals to reduce the harms of tobacco by helping adults who wish to quit smoking and deterring youth from starting to smoke. States can pay for initial investments in tobacco control through tax increases and recoup those investments through reduced expenditures on medical care.

Pathways for translating behavioral medicine research to practice and policy

The diversity of behavioral medicine, including investigators' disciplines, health conditions, settings, and intervention approaches, creates challenges for promoting the translation of research to practice and policy. Most papers on research translation focus on one pathway, so there is a need for a model that considers multiple pathways of research translation. The purpose is to propose a model of translating research to practice and policy that is broad enough to apply to many behavioral medicine scenarios and suggests options for behavioral medicine investigators to become engaged in research translation. This is a commentary, with examples drawn from scientific and gray literature. A model is proposed that describes five pathways of research translation: research, practice, business, policy, and public opinion. Target audiences, approaches, communication materials, and examples are suggested for each translation pathway. Resources are available for overcoming barriers to research translation. The main benefit of becoming engaged in research translation is a higher likelihood of health impact from the research. Researchers can choose one or more of the pathways of research translation that are suitable for their situation.

Bladder Cancer Stage Development, 2004-2014 in Europe Compared With the United States: Analysis of European Population-based Cancer Registries, the United States SEER Database, and a Large Tertiary Institutional Cohort

BACKGROUND

The purpose of this study was to analyze trends of bladder cancer (BC) stages and incidence in Europe and the United States (US).

MATERIALS AND METHODS

Tumor stages after radical cystectomy were assessed in a monocentric cohort from 2006 to 2016. BC incidence was assessed between 2004 and 2014 based on the German Center for Cancer Registry Data dataset at the Robert Koch Institute (n = 111,002), the Netherland Cancer Registry (n = 64,226), cancer registration statistics of England (n = 179,883), and the pooled data from the Scandinavian cancer registries, NORDCAN (n = 77,585) and the SEER (Surveillance, Epidemiology, and End Results) database (n = 184,519) for the complete populations and gender-specific subgroups. The average annual percent changes (AAPC) were used for statistical evaluation.

RESULTS

Non-muscle-invasive BC (NMIBC) and muscle-invasive BC (MIBC) did not change in the institutional cohort at the point of radical cystectomy. The incidence of total BC (AAPC, -0.3), NMIBC (AAPC, -0.1), and non-metastasized MIBC (AAPC, 0.1) did not change in Germany during the time period under survey. BC total incidence in the Netherlands did not change significantly. In England and the Nordic countries, the incidence of total BC increased (AAPC, 0.8 and 0.5, respectively). In contrast, both the incidence of total BC (AAPC, -1.4), NMIBC (AAPC, -1.6), and non-metastasized MIBC (AAPC, -1.6) significantly decreased in the US.

CONCLUSIONS

Between 2004 and 2014 the incidence of BC was significantly sinking in the US, was stable in Germany and the Netherlands, and increased in England and the Nordic countries. Predominantly, differences in the smoking prevalence within the last decades but also gender-specific factors might be responsible for this discrepancy.

Needs and Challenges Related to Multilevel Interventions: Physical Activity Examples

The theme of this commentary is to discuss the need for, and challenges of, conceptualizing, implementing, and evaluating multilevel health behavior change interventions. Ecological models, recommendations from national and international authoritative groups, and growing evidence all support the need for interventions designed to change multiple levels of influence, including individuals, social environments, organizations, built environments, and policies, to achieve population improvements in public health. Though multilevel interventions are becoming more common in practice, they are still under-used, and research on multilevel interventions is relatively rare. Drawing on examples from physical activity, several types of evidence are summarized to demonstrate that multilevel interventions are feasible and can be effective. Serious challenges to implementing and evaluating multilevel interventions include the need for teams with diverse expertise, lack of control over intervention implementation, unpredictability of timelines, managing complex teams over extended periods, and need to apply unfamiliar and less-rigorous study designs and methods. Recommendations are offered for changes in training, funding priorities, and academic incentives that could lead to more and better multilevel interventions.

Disadvantaged Social Groups and the Cigarette Epidemic: Limits of the Diffusion of Innovations Vision

The original four-stage model of the cigarette epidemic has been extended with diffusion of innovations theory to reflect socio-economic differences in cigarette use. Recently, two revisions of the model have been proposed: (1) separate analysis of the epidemic stages for men and women, in order to improve generalization to developing countries, and; (2) addition of a fifth stage to the smoking epidemic, in order to account for the persistence of smoking in disadvantaged social groups. By developing a cohort perspective spanning a 35-year time period in France and the USA, we uncover distinctive features which challenge the currently held vision on the evolution of smoking inequalities within the framework of the cigarette epidemic. We argue that the reason for which the model may not be fit to the lower educated is that the imitation mechanism underlying the diffusion of innovations works well with regard to adoption of the habit, but is much less relevant with regard to its rejection. Based on those observations, we support the idea that the nature and timing of the epidemic differs enough to treat the stages separately for high and low education groups, and discuss policy implications.

Effects of State-Level Tobacco Environment on Cigarette Smoking are Stronger Among Those With Individual-Level Risk Factors

INTRODUCTION

To better understand the impact of the state-level tobacco environment (eg, tobacco control policies, attitudes towards smoking) on cigarette smoking, we examined whether the relationship of state tobacco environments to smoking is modified by individual-level vulnerability factors.

METHODS

In a nationally representative sample of US adults (N = 34 638), past-year smoking and heavy smoking were examined. State-level tobacco environment was defined by tobacco-related control policies and attitudes, ranging from permissive to restrictive; individual vulnerability was defined by childhood maltreatment and/or parental substance problems. Additive interaction tested differences in state-level tobacco environment effects on smoking and heavy smoking by individual-level vulnerability.

RESULTS

Significant interactions (P values < .01) indicated that the state tobacco environment had the strongest relationship to smoking outcomes among individuals with greatest individual vulnerability. For example, among respondents with childhood maltreatment and parental substance problems, those in states with permissive tobacco environments had 13.3% greater prevalence of smoking than those in restrictive states. Among respondents with neither individual-level risk factor, those in permissive states had 2.8% greater prevalence than those in restrictive states (interaction P value = .0002).

CONCLUSIONS

Further restricting states' smoking environments could help reduce the prevalence of smoking and heavy smoking, particularly among those at increased individual risk in the general population.

IMPLICATIONS

This study shows that the protective effect of restrictive state-level tobacco environments on smoking or heavy smoking was stronger among those especially vulnerable due to individual-level risk factors (parental substance problems, childhood maltreatment). Thus, public health campaigns to influence attitudes towards smoking or legislation to strengthen tobacco control could have a broad effect, particularly impacting those with vulnerability to smoking, which may help decrease smoking prevalence and reduce the massive public health burden of tobacco-related morbidity and mortality.

A qualitative analysis of low income smokers' responses to tobacco excise tax increases

BACKGROUND

While increasing the excise tax applied to tobacco products reduces consumption and smoking prevalence, it may also cause hardship among smokers who do not quit. We explored how smokers living on a low income respond to increasing tobacco excise taxes.

METHODS

Using a social justice perspective, we explored the increasing costs of tobacco with a sample of 27 adult smokers who live below the poverty line (i.e., with an income less than 60% of the median New Zealand income). Face-to-face interviews were conducted in Dunedin, New Zealand, a city with marked income differences, and were undertaken shortly after a further tobacco excise tax increase. The interview guide explored participants' smoking practices, their perceptions of excise tax as a strategy to reduce smoking prevalence, and the strategies they used to manage their tobacco needs.

RESULTS

We identified three key themes: depriving the poor; tobacco as a precious commodity, and desperation. While many participants described smoking as a pleasure or coping mechanism, they also saw it as a burden that they struggled to manage. Despite trying to quit, most had failed to become smokefree and felt victimised by a punitive policy system that coerced change without supporting it. They managed financial pressure by reducing their tobacco consumption but also used increasingly desperate measures, including recycling waste tobacco; participants reported feeling demeaned by measures they saw as their only option.

CONCLUSION

Providing intensive cessation support for lower income smokers could avoid further alienating a group already experiencing considerable disadvantage.

Risk Factors for Smoking in Rural Women: The Role of Gender-Based Sexual and Intimate Partner Violence

BACKGROUND

Women living in Ohio Appalachia experience cervical cancer at disproportionately high rates. Intimate partner and sexual gender-based violence (GBV) and smoking are independent risk factors for cervical cancer and interact to heighten risk. Appalachian women smoke at higher rates than other Ohio women, but little is known about GBV exposure in the region. The purpose of this study was to establish prevalence of women's exposure to GBV in Ohio Appalachia and examine the association between GBV and smoking among women in the region.

METHODS

A two-phase address-based random sampling approach was used in three purposefully selected Ohio Appalachian counties to identify women to complete an interviewer administered cross-sectional survey (n = 398). The primary exposure variable was GBV Index Score, a 4 level indices representing increasing exposure to eight abuse types. Correlation analysis and logistic regression were used to examine smoking correlations and risk.

RESULTS

Almost 57% of women in the three selected Ohio Appalachian counties experienced GBV, with rate increasing to 77.5% among current smokers. The distribution of the GBV Exposure Index Score was significantly different across smoking status (p < = 0.0001), with exposure of GBV increasing when moving from never, to former, to current smokers. When controlling for depression, age, and adult socioeconomic position, GBV Exposure Index was significantly associated with current smoking behavior (OR:1.62, 95% CI [1.21-2.17]).

DISCUSSION

Professionals working to reduce disparate disease burden among women in Ohio Appalachia should consider the role GBV plays in health behavior and behavioral change interventions, including smoking and smoking cessation.

Tobacco control policy and socio-economic inequalities in smoking in 27 European countries

BACKGROUND

Higher Tobacco Control Scale (TCS) scores, in the early 2000s were associated with higher smoking cessation rates across Europe, both among lower and higher educated people. We aimed to assess if this association held in recent years.

METHODS

Repeated cross-sectional Eurobarometer surveys were used, in 27 European countries from 2006 to 2012 (study sample=73,617 adults). We used multilevel regression to model associations between the TCS (ranging from 0 to 100, quantifying: tobacco price, smoke-free laws, mass-media campaigns, advertising bans, warning labels, and cessation support) and both smoking cessation and cigarettes smoked per day. We modelled associations according to respondents' education and occupation, with adjustment for age, sex, and survey-wave.

RESULTS

We found no association between the TCS and smoking cessation for lower or middle educated respondents, but we did find an association for higher educated respondents (OR: 1.13, 95%CI: 1.08 to 1.19). For smoking intensity, we observed no associations with the TCS for lower educated respondents (beta: 0.04, 95%CI: -0.33 to 0.41) but we did observe significant associations for middle (beta: -0.25, 95%CI: -0.47 to -0.03) and higher educated respondents (beta: -0.27, 95%CI: -0.55 to -0.01). Associations were observed for both manual and non-manual classes, but not for those not working for pay. Of the TCS domains, none were associated with smoking cessation for lower educated respondents, but five were for higher educated respondents.

CONCLUSIONS

Associations between tobacco control policies and smoking cessation were found mostly among higher socioeconomic groups. This underlines the need for specific tobacco control policies that explicitly focus on reaching low socio-economic groups.

Social Networks and Smoking in Rural Women: Intervention Implications

OBJECTIVES

We characterized the social network characteristics of women in Ohio Appalachia according to smoking status.

METHODS

Women ≥18 years of age were recruited from 3 Ohio Appalachian counties to complete a cross-sectional survey. Sociodemographic and smoking-related information was collected by face-to-face interview. A description of women's time (ie, spends time with) and advice (ie, gets support and advice) social network ties were obtained. An egocentric social network analysis was completed, according to the woman's smoking status.

RESULTS

Of the 408 women enrolled, 20.1% were current smokers. Time networks were larger (p < .001), more dense (p < .001), and more redundant (p < .001) than advice networks. Current smokers had a greater proportion of smoking ties in their networks compared to non-smokers (p < .001). Daily face-to-face contact with non-smoking ties was greater in time compared to advice networks (p < .001). Current smokers in advice networks tended to have less daily contact with non-smoking ties than non-smokers (p = .06).

CONCLUSIONS

Differences existed in characteristics of time versus advice egocentric networks. Smoking status was associated with these differences. Results will assist with future development of a network-based smoking cessation intervention.

Daily Smoking and Subjective Health Complaints in Adolescence

INTRODUCTION

Using data from the Health Behaviour in School-aged Children survey, this study used a repeated cross-sectional design to examine associations between daily smoking, gender, and self-reported health complaints in five cohorts of adolescents over a 16-year period.

METHODS

Data were from nationally representative cohorts of 15-year-old youth in Norway in 1993/1994, 1997/1998, 2001/2002, 2005/2006, and 2009/2010 (n _total = 7761). Dependent variables were psychological, somatic, and total health complaints. A mixed GLM model examined main and interaction effects of smoking (daily, intermittent, nonsmoking), year, and gender in predicting complaints. Time periods were segmented to compare trends across smoking groups in specific periods.

RESULTS

Prevalence of daily smoking declined from 15.5% (1993/1994) to 6.0% (2009/2010). All health complaint scores were significantly higher for smokers and for girls (vs. boys). Smoking status by year interactions were significant for all complaint variables during the period of sharpest decline of daily smoking prevalence (2001/2002-2005/2006), with daily smokers experiencing increases in health complaints while intermittent and nonsmokers did not. Smoking status by gender interactions were significant for all health complaint variables, indicating that the main effect for gender (females higher) was even stronger among smokers compared with nonsmokers. Using year as unit of analysis, the size of mean differences between daily smokers and intermittent/nonsmokers in total complaints was significantly negatively correlated with daily smoking prevalence (-.963, n = 5, p < .01).

CONCLUSIONS

As prevalence of daily smoking declined, daily smokers reported higher levels of complaints, suggesting increasing health problems within this group. Girls who smoke daily had particularly elevated levels of complaints.

IMPLICATIONS

This study indicates that the relationship between daily smoking and concurrent health symptomatology in adolescents is changing over time, with higher levels of health complaints reported as overall smoking prevalence declines. To our knowledge, this finding has not previously been reported. If youth are smoking to cope with distress, pain, or other health concerns, tobacco control objectives will be increasingly difficult to achieve with adolescents. Levels of health complaints are particularly high among girls who are daily smokers. The findings suggest that restrictive measures and persuasive communications may not be sufficient tobacco prevention strategies for adolescent populations. Young smokers may need counseling and support.

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.

Integrating Tobacco Use Treatment Into Practice: Billing and Documentation

Balancing population-based efforts to modify the social and environmental factors that promote tobacco dependence with efforts to improve the delivery of case-based treatments is necessary for realizing maximum reductions in the cost and consequences of the disease. Public health antismoking campaigns following the 1964 Surgeon General's report on the health risks of smoking have changed social norms, prevented initiation among youth, and promoted abstinence among the addicted. However, the rate of progress enjoyed to date is unlikely to continue into the coming decades, given that current annual unassisted cessation rates among prevalent smokers remains fairly low. With more than 1 billion patient interactions annually, there is an enormous unrealized capacity for health-care systems to have an effect on this problem. Clinicians report a perceived lack of reimbursement as a significant barrier to full integration of tobacco dependence into health care. A more complete understanding of the coding and documentation requirements for successful practice in this critically important area is a prerequisite to increasing engagement. This paper presents several case-based scenarios illustrating important practice management issues related to the treatment of tobacco dependence in health care.

Estimating the 'consumer surplus' for branded versus standardised tobacco packaging

BACKGROUND

Tobacco companies question whether standardised (or 'plain') packaging will change smokers' behaviour. We addressed this question by estimating how standardised packaging compared to a proven tobacco control intervention, price increases through excise taxes, thus providing a quantitative measure of standardised packaging's likely effect.

METHODS

We conducted an online study of 311 New Zealand smokers aged 18 years and above that comprised a willingness-to-pay task comparing a branded and a standardised pack at four different price levels, and a choice experiment. The latter used an alternative-specific design, where the alternatives were a branded pack or a standardised pack, with warning theme and price varied for each pack.

RESULTS

Respondents had higher purchase likelihoods for the branded pack (with a 30% warning) than the standardised pack (with a 75% warning) at each price level tested, and, on average, were willing to pay approximately 5% more for a branded pack. The choice experiment produced a very similar estimate of 'consumer surplus' for a branded pack. However, the size of the 'consumer surplus' varied between warning themes and by respondents' demographic characteristics.

CONCLUSIONS

These two experiments suggest standardised packaging and larger warning labels could have a similar overall effect on adult New Zealand smokers as a 5% tobacco price increase. The findings provide further evidence for the efficacy of standardised packaging, which focuses primarily on reducing youth initiation, and suggest this measure will also bring notable benefits to adult smokers.

Tobacco Use Among Healthcare Workers: Impact of a Worksite Policy Change at a US Military Community Hospital

Introductions:Healthcare workers use less tobacco than other working populations. In contrast, US military members use more tobacco than civilians. Military healthcare workers, therefore, represent a unique group with regard to occupational factors that may influence tobacco use.

Aims/Methods:Records of workers at a military community hospital were reviewed to describe tobacco use. An anonymous survey assessed impressions of a worksite policy change that prohibited tobacco use anywhere on hospital grounds.

Results:Hospital staff included 2,074 professionals. Tobacco use was significantly associated with male sex and being a military enlisted worker. In fact, 37% of male enlisted members used tobacco; fewer than 10% of all other workers used tobacco. Among 232 survey respondents, 61% agreed with tobacco-restrictive worksite policies, but only 33% thought policies were effective. Nearly one-third of tobacco users reported decreasing use in the past year. In multivariable modelling, changing habits in response to worksite policy was the only factor significantly associated with decreased tobacco use.

Conclusions:Tobacco use among US military healthcare workers varies markedly by demographic characteristics. Male, military enlisted workers use tobacco at very high rates, paralleling the troops they serve. Implementation of tobacco-restrictive worksite policies is associated with decreased tobacco use in this population.

Low expression of dendritic cell-specific intercellular adhesion molecule-grabbing nonintegrin-related protein in lung cancer and significant correlations with brain metastasis and natural killer cells

Dendritic cell-specific intercellular adhesion molecule-grabbing nonintegrin-related protein (DC-SIGNR) is a type II transmembrane protein which has been reported to bind a variety of pathogens as well as participate in immunoregulation. But the association between the level of DC-SIGNR and lung cancer is unknown. To investigate the clinical diagnostic significance of DC-SIGNR in lung cancer, we investigated serum DC-SIGNR levels in 173 lung cancer patients and 134 healthy individuals using enzyme-linked immunosorbent assay (ELISA). Results showed that serum DC-SIGNR levels in lung cancer patients were lower than that in healthy controls (P = 0.0003). A cut-off value of 3.8998 ng/L for DC-SIGNR predicted the presence of lung cancer with 78.03% sensitivity and 49.25% specificity (area under the curve = 0.6212, P = 0.0003). Strikingly, serum DC-SIGNR levels were significantly higher in lung cancer patients with brain metastasis compared to those without metastasis (P = 0.0283). Moreover, the serum concentrations of DC-SIGNR in lung cancer patients also correlated significantly with serum natural killer cells percentage (P = 0.0017). In addition, immunohistochemistry assay demonstrated that the expression of DC-SIGNR in lung tissues of 31 lung cancer patients and 13 tuberculosis patients was significantly lower than that in 18 normal lung tissues (P = 0.0418, 0.0289), and there is no significant difference between tuberculosis tissues and lung cancer tissues (P = 0.2696). These results suggest that DC-SIGNR maybe a promising biological molecule that has the potential for clinical research of lung cancer, whereas its underlying roles are needed to be investigated in further studies.

The media and behavioral genetics: Alternatives coexisting with addiction genetics

To understand public discourse in the U.S. on genetic causation of behavioral disorders, we analyzed media representations of genetic research on addiction published between 1990 and 2010. We conclude first that the media simplistically represent biological bases of addiction and willpower as being mutually exclusive: behaviors are either genetically determined, or they are a choice. Second, most articles provide only cursory or no treatment of the environmental contribution. A media focus on genetics directs attention away from environmental factors. Rhetorically, media neglect the complexity underlying of the etiology of addiction and direct focus back toward individual causation and responsibility.

Mathematical Modeling in Tobacco Control Research: Initial Results From a Systematic Review

OBJECTIVES

The US Food and Drug Administration has expressed interest in using mathematical models to evaluate potential tobacco policies. The goal of this systematic review was to synthesize data from tobacco control studies that employ mathematical models.

METHODS

We searched five electronic databases on July 1, 2013 to identify published studies that used a mathematical model to project a tobacco-related outcome and developed a data extraction form based on the ISPOR-SMDM Modeling Good Research Practices. We developed an organizational framework to categorize these studies and identify models employed across multiple papers. We synthesized results qualitatively, providing a descriptive synthesis of included studies.

RESULTS

The 263 studies in this review were heterogeneous with regard to their methodologies and aims. We used the organizational framework to categorize each study according to its objective and map the objective to a model outcome. We identified two types of study objectives (trend and policy/intervention) and three types of model outcomes (change in tobacco use behavior, change in tobacco-related morbidity or mortality, and economic impact). Eighteen models were used across 118 studies.

CONCLUSIONS

This paper extends conventional systematic review methods to characterize a body of literature on mathematical modeling in tobacco control. The findings of this synthesis can inform the development of new models and the improvement of existing models, strengthening the ability of researchers to accurately project future tobacco-related trends and evaluate potential tobacco control policies and interventions. These findings can also help decision-makers to identify and become oriented with models relevant to their work.

Estimating the benefits of public health policies that reduce harmful consumption

For products such as tobacco and junk food, where policy interventions are often designed to decrease consumption, affected consumers gain utility from improvements in lifetime health and longevity but also lose utility associated with the activity of consuming the product. In the case of anti-smoking policies, even though published estimates of gross health and longevity benefits are up to 900 times higher than the net consumer benefits suggested by a more direct willingness-to-pay estimation approach, there is little recognition in the cost-benefit and cost-effectiveness literature that gross estimates will overstate intrapersonal welfare improvements when utility losses are not netted out. This paper presents a general framework for analyzing policies that are designed to reduce inefficiently high consumption and provides a rule of thumb for the relationship between net and gross consumer welfare effects: where there exists a plausible estimate of the tax that would allow consumers to fully internalize health costs, the ratio of the tax to the per-unit long-term cost can provide an upper bound on the ratio of net to gross benefits.

Socioeconomic inequalities in smoking cessation in 11 European countries from 1987 to 2012

BACKGROUND

During the 1990s, inequalities in smoking prevalence by socioeconomic status (SES) have widened in Europe. Since then, many tobacco control policies have been implemented. Yet, European overviews of recent trends in smoking inequalities are lacking. This paper aims to provide an overview of long-term trends of socioeconomic inequalities in smoking cessation in Europe.

METHODS

We used data for 11 countries taken from Eurobarometer surveys from 1987 to 1995 and 2002-2012, with a total study sample of 63 737 respondents. We performed multilevel logistic regression to model associations of the quit ratio (proportion former smokers of ever smokers) with SES, measured by education and occupation separately, with adjustments for age, sex and time.

RESULTS

We found a significant, positive association for education and occupation with the quit ratio. The strength of the association decreased slightly from 1987 to 1995 and increased again from 2002 to 2012. Inequalities increased between the two periods in most countries and decreased in only one country. While in 1987-1995, the quit ratio increased among all SES groups and most strongly among the low SES group, in 2002-2012 it increased only among the high-education group (OR=1.38, 95% CI 1.02 to 1.87), and non-manual occupation group (OR=1.59, 95% CI 1.19 to 2.12).

CONCLUSIONS

Socioeconomic inequalities in smoking cessation rates have strongly increased since the 1990s and during the 2000s. This suggests that the tobacco control policies implemented during the 2000s have not been able to counter the trend in increasing inequalities.

An evaluation of the FDA's analysis of the costs and benefits of the graphic warning label regulation

The Family Smoking Prevention and Tobacco Control Act of 2009 gave the Food and Drug Administration (FDA) regulatory authority over cigarettes and smokeless tobacco products and authorised it to assert jurisdiction over other tobacco products. As with other Federal agencies, FDA is required to assess the costs and benefits of its significant regulatory actions. To date, FDA has issued economic impact analyses of one proposed and one final rule requiring graphic warning labels (GWLs) on cigarette packaging and, most recently, of a proposed rule that would assert FDA’s authority over tobacco products other than cigarettes and smokeless tobacco. Given the controversy over the FDA's approach to assessing net economic benefits in its proposed and final rules on GWLs and the importance of having economic impact analyses prepared in accordance with sound economic analysis, a group of prominent economists met in early 2014 to review that approach and, where indicated, to offer suggestions for an improved analysis. We concluded that the analysis of the impact of GWLs on smoking substantially underestimated the benefits and overestimated the costs, leading the FDA to substantially underestimate the net benefits of the GWLs. We hope that the FDA will find our evaluation useful in subsequent analyses, not only of GWLs but also of other regulations regarding tobacco products. Most of what we discuss applies to all instances of evaluating the costs and benefits of tobacco product regulation and, we believe, should be considered in FDA's future analyses of proposed rules.

A comparison of on-pack Quitline information formats

BACKGROUND

Although tobacco packages have evolved to feature health warnings and, in Australia, dissuasive colours, the format of on-pack cessation information has not changed. We compared how alternative Quitline information formats affected smokers' perceptions and choice behaviours, and their likelihood of seeking cessation support.

METHODS

We conducted an online study comprising a choice experiment using a two (number of panels) by three (panel position: above, middle, below) plus control (current format) design, and a between-subjects comparison of a two-panel format and the control. The sample comprised 608 New Zealand smokers.

RESULTS

Relative to the current format, respondents regarded each test format as more effective in communicating cessation information (p<0.0001), particularly the two-panel formats. Respondents found the two-panel format tested via paired comparisons significantly easier to read, more visually salient and more likely than the control to encourage them and other smokers to consider quitting (all p<0.0001). Heat map comparisons showed that the Quitline number and affirming message were significantly more salient in the test format than in the current format (p<0.0001), although the headline and warning explanation were more salient in the control.

CONCLUSIONS

Reformatting Quitline information could improve its visual salience and readability and capitalise on the dissonance that pictorial warning labels and plain packaging create. Enhancing stimuli that may prompt smokers to try and quit, affirming their decision to do so and prompting the use of cessation support could increase the number and success of quit attempts.

Tobacco control policies and their impacts. Past, present, and future

The 1964 Surgeon General's report on smoking and health concluded that "Cigarette smoking is a health hazard of sufficient importance in the United States to warrant appropriate remedial action." The adoption of remedial actions over the next half century produced what is arguably the most important public health triumph of that period in the United States and in other developed nations. At the heart of the remedial actions were governmental policies. By raising cigarette price, taxation is especially effective at reducing smoking, encouraging some smokers to quit and others to reduce their daily consumption, while also discouraging the initiation of smoking by children. Smoke-free workplace policies have dramatically reduced workers' exposure to the toxins in cigarette smoke, smoking, employers' costs, and the incidence of acute myocardial infarctions. Other policies have also helped diminish the toll of smoking. The successes of tobacco control notwithstanding, future progress will occur slowly unless society finds new, possibly radical "endgame" strategies to hasten the arrival of a smoke-free society.

Does Screening Participation Affect Cigarette Smokers' Decision to Quit? A Long-Horizon Panel Data Analysis

Background

Despite decades of intensive anti-tobacco initiatives, millions of people are still smoking. The health authorities are seeking new tools and extended knowledge. Screening programs may, in addition to the potential health benefits from early detection of smoking related diseases, also increase smoking cessation among participants. This study examines the effect of screening participation by comparing the smokers' cessation hazard in screening years to non-screening years.

Methods

All smokers (n=10,471) participated in a three-wave cardiovascular screening and were followed up over a maximum of 14 years. The panel was merged with administrative registers. We used a flexible discrete-time duration model to investigate the effect of the screening program while simultaneously accounting for the possible influence of personal characteristics, addiction indicators, economic factors, health status and health changes. Specifically, we examined and compared long-term smokers (LT; smoked ≥25 years) with short-term (ST; smoked ≤ 5 years) and medium-term (MT; smoked 10-20 years) smokers.

Results

We found that 29% of LT smokers quitted smoking during the follow-up whereas 32% of MT and 48% of ST smokers reported the same. The screening participation years stood out as especially important for all groups. The impact of the first screening was particularly high, and for the first two screenings, the effect was higher for long-term smokers than for the smokers with shorter smoking careers. Receiving an abnormal test result was not associated with a significant increase in cessation hazard for any group of smokers.

Conclusions

The substantial effect of being invited to and participating in a screening appears robust, and may prove useful when discussing future policies for smoking cessation. This paper suggests that further initiatives for consultations with health personnel, in this case through a screening program, could increase the quitting hazard.

Trends in smoking among adults with mental illness and association between mental health treatment and smoking cessation

IMPORTANCE

Significant progress has been made in reducing the prevalence of tobacco use in the United States. However, tobacco cessation efforts have focused on the general population rather than individuals with mental illness, who demonstrate greater rates of tobacco use and nicotine dependence.

OBJECTIVES

To assess whether declines in tobacco use have been realized among individuals with mental illness and examine the association between mental health treatment and smoking cessation.

DESIGN, SETTING, AND PARTICIPANTS

Use of nationally representative surveys of noninstitutionalized US residents to compare trends in smoking rates between adults with and without mental illness and across multiple disorders (2004-2011 Medical Expenditure Panel Survey [MEPS]) and to compare rates of smoking cessation among adults with mental illness who did and did not receive mental health treatment (2009-2011 National Survey of Drug Use and Health [NSDUH]).The MEPS sample included 32,156 respondents with mental illness (operationalized as reporting severe psychological distress, probable depression, or receiving treatment for mental illness) and 133,113 without mental illness. The NSDUH sample included 14,057 lifetime smokers with mental illness.

MAIN OUTCOMES AND MEASURES

Current smoking status (primary analysis; MEPS sample) and smoking cessation, operationalized as a lifetime smoker who did not smoke in the last 30 days (secondary analysis; NSDUH sample).

RESULTS

Adjusted smoking rates declined significantly among individuals without mental illness (19.2% [95% CI, 18.7-19.7%] to 16.5% [95% CI, 16.0%-17.0%]; P < .001) but changed only slightly among those with mental illness (25.3% [95% CI, 24.2%-26.3%] to 24.9% [95% CI, 23.8%- 26.0%]; P = .50), a significant difference in difference of 2.3% (95% CI, 0.7%-3.9%) (P = .005). Individuals with mental illness who received mental health treatment within the previous year were more likely to have quit smoking (37.2% [95% CI, 35.1%-39.4%]) than those not receiving treatment (33.1% [95% CI, 31.5%-34.7%]) (P = .005).

CONCLUSIONS AND RELEVANCE

Between 2004 and 2011, the decline in smoking among individuals with mental illness was significantly less than among those without mental illness, although quit rates were greater among those receiving mental health treatment. This suggests that tobacco control policies and cessation interventions targeting the general population have not worked as effectively for persons with mental illness.

Minimising the harm from nicotine use: finding the right regulatory framework

The tobacco problem can be usefully conceptualised as two problems: eliminating the most harmful forms of nicotine use (certainly cigarettes, and probably all smoked tobacco), and minimising the use and/or harms from use of lower-harm, but addictive forms of nicotine. A possible target would be to effectively eliminate use of the most harmful forms of nicotine within the next decade and then turn our focus to a long-term strategy for the low-harm forms. This paper focuses on the administrative framework(s) needed to accomplish these twin tasks. For a phase-out taking a long time and/or for dealing with residually net harmful and addictive products, there are severe limitations to allowing for-profit marketing of tobacco because such an arrangement (the current one in most countries) can markedly slow down progress and because of the difficulty of constraining marketing in ways that minimise undesirable use. A harm reduction model where the marketing is under the control of a non-profit entity (a regulated market) is required to curtail the incredible power of for-profit marketing and to allow tobacco marketing to be done in ways that further the goal of minimising tobacco-related harm. Countries with a nationalised industry can move their industry onto a harm minimisation framework if they have the political will. Countries with a for-profit industry should consider whether the time and effort required to reconstruct the market may, in the longer term, facilitate achieving their policy goals.

An endgame for tobacco?

Since its origins in the 1960s, tobacco control has achieved remarkable success against the scourge of tobacco-produced disease and death. Yet tobacco use, especially cigarette smoking, remains the world's leading cause of preventable premature death and is likely to do so for decades to come. Evidence-based policies seem incapable of substantially hastening the demise of smoking. Slowness in the decline of smoking in developed nations, and increasing smoking in many low- and middle-income countries has sparked interest in novel, even radical 'endgame' strategies to eliminate the toll of tobacco. This paper identifies the principal endgame proposals and, with the other papers in this volume, has the goal of expanding and deepening the endgame conversation by engaging the broader tobacco control community. While we struggle today with often widely divergent perspectives and beliefs about what is possible and how it might be achieved, we all share the same vision of the final words to this story: ‘The end’.

Tobacco endgame strategies: challenges in ethics and law

There are complex legal and ethical tradeoffs involved in using intensified regulation to bring smoking prevalence to near-zero levels. The authors explore these tradeoffs through a lens of health justice, paying particular attention to the potential impact on vulnerable populations. The ethical tradeoffs explored include the charge that heavy regulation is paternalistic; the potentially regressive impact of heavily taxing a product consumed disproportionately by the poor; the simple loss of enjoyment to heavily addicted smokers; the health risks posed by, for example, regulating nicotine content in cigarettes—where doing so leads to increased consumption. Turning to legalistic concerns, the authors explore whether endgame strategies constitute a form of ‘regulatory taking’; whether endgame strategies can be squared with global trade/investment laws; whether free speech rights are infringed by aggressive restrictions on the advertisement and marketing of cigarettes.

Development of an integrated tobacco endgame strategy

In recent years, various tobacco 'endgame' strategies have been suggested as a means to phase out tobacco consumption. Using country examples, this paper discusses three potential strategies: replacing cigarettes with alternative products (harm reduction), denying tobacco sales to people born after a certain year (the tobacco-free generation proposal), and further implementing measures based on the WHO Framework Convention for Tobacco Control (FCTC) treaty. It is argued that all strategies have potential issues that could be avoided by combining them into an integrated, sequential endgame that, first, using measures recommended in the WHO FCTC, creates a climate that facilitates the phasing out of cigarettes; second, implements a generational phase out of cigarette sales; and third, simultaneously permits the regulated use of alternative nicotine products. Thus, integrating ideas from various endgame strategies will result in a more effective, resilient tobacco endgame policy.

Environmental determinants of smoking behaviors: The role of policy and environmental interventions in preventing smoking initiation and supporting cessation

Tobacco control strategies have contributed to substantial declines in smoking in the United States. However, smoking still remains the single largest preventable cause of disease and premature deaths in the country. Despite the continuing challenges of implementing tobacco control strategies and the pervasive influence of the tobacco industry to undermine such strategies, there are now unprecedented opportunities to prevent smoking initiation, facilitate cessation, and protect nonsmokers from secondhand smoke. In this paper, we briefly review the most recent literature discussing key strategies that have proven effective in tobacco control including regulations on sales and marketing of tobacco products, taxation, and smoke-free legislation. We focused on these three tobacco control strategies because of their potential to positively influence the environment of both minors and adults regardless of their smoking status. Although research has identified significant individual and social predictors of tobacco use, environmental influences are also important risk factors for tobacco use.

Effectiveness of electronic aids for smoking cessation

Tobacco use continues to be the leading cause of preventable death in the world, and though current evidence-based approaches have substantially reduced rates of smoking, these rates remain disturbingly high. Two recent technological advancements, the electronic cigarette (e-cigarette) and mobile health (mHealth) interventions, may offer smokers an alternative way to quit smoking. E-cigarettes continue to be fiercely debated. Preliminary evidence suggests that e-cigarettes are likely much safer than regular cigarettes and are helpful to some smokers as a means of reducing or quitting smoking. Questions, however, still remain as to how they will affect overall public health-if they will be used as a "gateway" product or reduce motivation to quit smoking, to name but a few. Similarly, mHealth interventions appear to be effective and accepted by users. However, mobile 'apps' have yet to be tested in randomized trials and there are concerns about violations of users privacy and state jurisdictions.

Child physical and sexual abuse and cigarette smoking in adolescence and adulthood

PURPOSE

Analyses used data from an extended longitudinal study to examine the relationship between childhood physical and sexual abuse (CPA and CSA, respectively) and adolescent and adult smoking behavior. Two questions guided the study: (1) Is there an association between childhood abuse and adolescent and adult smoking behavior? (2) Does the relationship between childhood abuse and later cigarette smoking differ for males and females?

METHODS

A censored-inflated path model was used to assess the impact of child abuse on adolescent and adult lifetime smoking prevalence and smoking frequency. Gender differences in significant model paths were assessed using a multiple-group approach.

RESULTS

Results show no significant relation between CPA or CSA and risk of having ever smoked cigarettes in adolescence or adulthood. However, for males, both CPA and CSA had direct effects on adolescent smoking frequency. For females, only CSA predicted increased smoking frequency in adolescence. Adolescent smoking frequency predicted adult smoking frequency more strongly for females compared with males.

CONCLUSIONS

CPA and CSA are risk factors for higher frequency of smoking in adolescence. Higher frequency of cigarette smoking in adolescence increases the risk of higher smoking frequency in adulthood. Results underscore the need for both primary and secondary prevention and intervention efforts to reduce the likelihood of childhood abuse and to lessen risk for cigarette smoking among those who have been abused.

Effects of the economic crisis on smoking prevalence and number of smokers in the USA

OBJECTIVE

Scanty and controversial information is available on the impact of macroeconomic fluctuations on smoking behaviour. No study has quantified the effects of fiscal crises on smoking prevalence. This study aimed to investigate the effects of the 2007-2008 economic crisis on smoking prevalence and number of smokers in the USA.

METHODS

Using data from the repeated Behavioural Risk Factor Surveillance System (BRFSS) surveys in pre-crisis (2005-2007) and post-crisis (2009-2010) periods on a total of 1,981,607 US adults, we separated the expected (after allowance for the demographic growth of the US population, secular smoking prevalence trends and changes in sociodemographic characteristics) from the unexpected (assumed attributable to the economic crisis) changes in the number of smokers across different employment statuses.

RESULTS

Joinpoint regression analysis revealed no significant changes in smoking prevalence trends over the period 2005-2010. The crisis resulted in an increase in the number of smokers in the US by 0.6 million. This is largely due to an unexpected decrease of 1.7 million smokers among employed and an increase of 2.4 million smokers among unemployed individuals, whose smoking prevalence also remains extremely high in the post-crisis period (32.6%).

CONCLUSIONS

The 2008 financial crisis had a weak effect on smoking prevalence. The pro-cyclical relationship (ie, the crisis results in a lower number of smokers) found among the employed is offset by the counter-cyclical relationship (ie, the crisis results in a higher number of smokers) found among unemployed individuals. Public health interventions should specifically target those in unemployment, particularly in hard times.

Smoking, mental illness and socioeconomic disadvantage: analysis of the Australian National Survey of Mental Health and Wellbeing

BACKGROUND

High rates of smoking and lower rates of smoking cessation are known to be associated with common mental disorders such as anxiety and depression, and with individual and community measures of socioeconomic status. It is not known to what extent mental illness and socioeconomic status might be jointly associated with smoking behaviour. We set out to examine the relationship between mental illness, measures of socioeconomic disadvantage and both current smoking and smoking cessation rates.

METHODS

We used data from the 2007 Australian National Survey of Mental Health and Wellbeing to examine the relationship between mental illness, socioeconomic status and both current smoking and smoking cessation. We used cross-classified tables and logistic regression to examine the relationship between psychosocial and sociodemographic predictors and current smoking. We also used proportional hazards regression to examine the relationship between the factors and smoking cessation.

RESULTS

Both mental illness and socioeconomic status were independently associated with current smoking and with lower likelihood of smoking cessation, with gradients in smoking by mental health status being observed within levels of socioeconomic indicators and vice versa. Having a mental illness in the past 12 months was the most prevalent factor strongly associated with smoking, affecting 20.0% of the population, associated with increased current smoking (OR 2.43; 95% CI: 1.97-3.01) and reduced likelihood of smoking cessation (HR: 0.77; 95% CI: 0.65-0.91).

CONCLUSIONS

The association between mental illness and smoking is not explained by the association between mental illness and socioeconomic status. There are strong socioeconomic and psychosocial gradients in both current smoking and smoking cessation. Incorporating knowledge of the other adverse factors in smokers' lives may increase the penetration of tobacco control interventions in population groups that have historically benefitted less from these activities.

Political impediments to a tobacco endgame

Any serious consideration of exploring a tobacco endgame in the USA must build upon the enviable track record of reducing tobacco use through a mixture of federal and state policies. This foundation may pose particular challenges in approaching an endgame, including questions of national political feasibility, public support, limitations of sub-federal experimentation and recruitment of future political champions. Advocates must demonstrate a compelling need for a dramatic expansion beyond existing efforts, amid competition from alternative issues and little apparent public appetite for such an initiative.

Smoking prevalence among migrants in the US compared to the US-born and the population in countries of origin

OBJECTIVES

Smoking among migrants is known to differ from the host population, but migrants' smoking is rarely ever compared to the prevalence of smoking in their country of origin. The goal of this study is to compare the smoking prevalence among migrants to that of both the US-born population and the countries of origin. Further analyses assess the influence of sex, age at time of entry to the US and education level.

METHODS

Data of 248,726 US-born and migrants from 14 countries were obtained from the Tobacco Use Supplement to the Current Population Survey (TUS-CPS) from 2006-2007. Data on 108,653 respondents from the corresponding countries of origin were taken from the World Health Survey (WHS) from 2002-2005.

RESULTS

The prevalence of smoking among migrants (men: 14.2%, women: 4.1%) was lower than both the US-born group (men: 21.4%, women: 18.1%) and countries of origin (men: 39.4%, women: 11.0%). The gender gap among migrants was smaller than in the countries of origin. Age at time of entry to the US was not related to smoking prevalence for migrants. The risk of smoking for high-educated migrants was closer to their US counterparts.

CONCLUSIONS

The smoking prevalence among migrants is consistently lower than both the country of origin levels and the US level. The theory of segmented assimilation is supported by some results of this study, but not all. Other mechanisms that might influence the smoking prevalence among migrants are the 'healthy migrant effect' or the stage of the smoking epidemic at the time of migration.

Making sense of "consumer engagement" initiatives to improve health and health care: a conceptual framework to guide policy and practice

CONTEXT

Policymakers and practitioners continue to pursue initiatives designed to engage individuals in their health and health care despite discordant views and mixed evidence regarding the ability to cultivate greater individual engagement that improves Americans' health and well-being and helps manage health care costs. There is limited and mixed evidence regarding the value of different interventions.

METHODS

Based on our involvement in evaluating various community-based consumer engagement initiatives and a targeted literature review of models of behavior change, we identified the need for a framework to classify the universe of consumer engagement initiatives toward advancing policymakers' and practitioners' knowledge of their value and fit in various contexts. We developed a framework that expanded our conceptualization of consumer engagement, building on elements of two common models, the individually focused transtheoretical model of behavior and the broader, multilevel social ecological model. Finally, we applied this framework to one community's existing consumer engagement program.

FINDINGS

Consumer engagement in health and health care refers to the performance of specific behaviors ("engaged behaviors") and/or an individual's capacity and motivation to perform these behaviors ("activation"). These two dimensions are related but distinct and thus should be differentiated. The framework creates four classification schemas, by (1) targeted behavior types (self-management, health care encounter, shopping, and health behaviors) and by (2) individual, (3) group, and (4) community dimensions. Our example illustrates that the framework can systematically classify a variety of consumer engagement programs, and that this exercise and resulting characterization can provide a structured way to consider the program and how its components fit program goals both individually and collectively.

CONCLUSIONS

Applying the framework could help advance the field by making policymakers and practitioners aware of the wide range of approaches, providing a structured way to organize and characterize interventions retrospectively, and helping them consider how they can meet the program's goals both individually and collectively.

Tackling the global NCD crisis: innovations in law and governance

35 million people die annually of non-communicable diseases (NCDs), 80% of them in low- and middle-income countries - representing a marked epidemiological transition from infectious to chronic diseases and from richer to poorer countries. The total number of NCDs is projected to rise by 17% over the coming decade, absent significant interventions. The NCD epidemic poses unique governance challenges: the causes are multifactorial, the affected populations diffuse, and effective responses require sustained multi-sectorial cooperation. The authors propose a range of regulatory options available at the domestic level, including stricter food labeling laws, regulation of food advertisements, tax incentives for healthy lifestyle choices, changes to the built environment, and direct regulation of food and drink producers. Given the realities of globalization, such interventions require global cooperation. In 2011, the UN General Assembly held a High-level meeting on NCDs, setting a global target of a 25% reduction in premature mortality from NCDs by 2025. Yet concrete plans and resource commitments for reaching this goal are not yet in the offing, and the window is rapidly closing for achieving these targets through prevention - as opposed to treatment, which is more costly. Innovative global governance for health is urgently needed to engage private industry and civil society in the global response to the NCD crisis.
