Introduction: Transit workers are a blue-collar occupational group with elevated rates of smoking despite access to free or low-cost cessation services available through their health insurance as a union-negotiated employee benefit. Little is known about the influences on cessation participation in this workforce.

Aims: The purpose of this study is to analyse the factors associated with past-year cessation activities amongst a multiethnic sample of transit workers.

Methods: Cross-sectional tobacco surveys were completed by 935 workers at an Oakland, California, USA-based public transit agency. Data from 190 current smokers (68% African American; 46% female) were analysed. Adjusted odds ratios were calculated to identify factors associated with past-year cessation activity.

Results: Approximately 55% of smokers stopped smoking for one day or longer during the past year in order to quit. Nearly half reported that the most common barrier to quitting was, ‘Not mentally ready to quit because I like smoking’. Workers in the contemplation/precontemplation stage for intention to quit were less likely to have engaged in cessation activities than those in the action/preparation stage (AOR = 0.34). Frequency of coworker encouragement for quitting was positively associated with past-year cessation activities (AOR = 3.25). Frequency of insomnia symptoms was negatively associated with cessation activity participation (AOR = 0.34).

Conclusions: Most transit workers who smoke made a past-year quit attempt. Gaining insight into factors associated with participation in cessation activities can aid worksite efforts to promote cessation and reduce tobacco-related disparities.

Introduction: Weight gain during smoking cessation is a major concern. The relationship between smoking and weight is complex and not well understood. There is interest in substitution of nicotine with food.

Aims: This study investigates whether the development of food addiction explains weight gain following a quit smoking attempt.

Methods: This study was a subset of a larger study investigating smoking cessation in New Zealand. Participants were assessed on five visits over a 1-year period. Using validated instruments, measurements for smoking, weight, food intake, craving and food addiction were taken.

Results: Among the 256 participants, 54.7% attended at least one follow-up. Food addiction prevalence at baseline was 0.8%. 14.5% were quit at early follow-up and 14.8% at late follow-up. Weight gain was found in abstainers compared to those still smoking. No increase in food addiction was detected.

Conclusion: The development of food addiction does not play a prominent role in post quit weight gain. Further research is needed to elucidate the underlying weight gain mechanisms.

Introduction: Attempts to quit smoking have increased in recent years, but the patterns of variations over time are unknown. We aimed at describing time- and sex-related changes in a population of 2,231 subjects who adhered to a smoking-cessation programme lasting 13 years in Italy.

Methods: We measured baseline expired carbon monoxide (expired-CO), Fagerstrom nicotine dependence, Q-MAT test, Zung depression and anxiety scale, Hospital anxiety and depression scale (HADS).

Results: Study population included 1,278 men and 953 women who smoked a median of 25 (interquartile range, IQR: 20–32) and 20 (IQR: 20–30) cigarettes/day, respectively (p < 0.001). The proportion of female smokers increased from 37.5% in 2001–2003 to 46.9% in 2010–2013 (p = 0.003). There was a significant time-related reduction of median daily cigarette consumption, with a more noticeable decrease in men. Median expired-CO (parts per million (ppm)) increased only in women, from 18 (IQR: 14–23) in 2001–03 to 20 (IQR: 14–28) in 2010–13 (p = 0.001), whereas Fagerstrom test for nicotine dependence did not vary. Differences in psychological characteristics in the last 3 years showed that women were more clinically depressed than men (16.6% versus 7.6%, p < 0.001).

Conclusions: Despite a decrease in the number of daily cigarettes with time, expired-CO tends to increase in women, who are also more clinically depressed and anxious than men. A personalised approach to specific subgroups of smokers, with special emphasis on a psychological support for women, seems appropriate.

While the global smoking rate has dropped in the past 30 years (from 41.2% of men in 1980 to 31.1% in 2012 and from 10.6% of women in 1980 to 6.2% in 2012), the number of tobacco smokers has increased due to population growth (Ng et al., 2014). This tobacco use and second-hand smoke exposure continue to harm people worldwide. Those harmed are often vulnerable: children, those living in low- and middle-income countries (LMICs), those with existing diseases, etc. As noted by the World Health Organization (WHO), nearly 80% of those who smoke live in a LMIC (World Health Organization, 2017). Furthermore, it is often those who are more socio-economically disadvantaged or less educated in LMICs that are exposed to second-hand smoke at home and work (Nazar, Lee, Arora, & Millett, 2015).

Introduction: Weight concerns may inhibit smoking quit attempts and may be more influential amongst African-Americans who are more likely to be overweight.

Aims: To assess if weight perception is associated with readiness to quit and whether this relationship is modified by race.

Methods: We used data from a cohort of current smokers undergoing routine health examinations. Based on differences between ideal and measured BMI, participants’ weight perceptions were classified as within, somewhat above, or far above ideal weight. Logistic regression analysis was used to evaluate adjusted associations of weight perception and race with readiness to quit.

Results: Of 2,831 current smokers, 23% were obese and 38% overweight. Amongst white smokers, those who perceived being far above ideal weight were more likely to be ready to quit (OR: 1.45, 95% CI: 1.03–2.03), but this association was not observed for African-American smokers who perceived themselves to be somewhat or far above their ideal weight (OR: 0.35, 95% CI: 0.10–1.24 and OR: 0.36, 95% CI: 0.11–1.19, respectively).

Conclusions: Perception of being overweight is associated with increased readiness to quit amongst white but not African-American smokers. Smoking cessation programmes may need to culturally tailor interventions based on smokers’ weight perceptions.

We evaluated the feasibility of incorporating integrated care (IC) for smoking cessation into routine care for homeless veterans at seven Department of Veterans Affairs (VA) Medical Centers and the utility of the learning collaborative (LC) model in facilitating implementation. The goal of IC is for clinicians to provide smoking cessation concurrent with other clinical duties. The LC model utilises multidisciplinary teams and recognised field experts to develop methods for accelerating the use of evidence-based treatments. Multidisciplinary teams comprising 34 (of about 175) staff members from seven VA homeless provider teams participated. Via self-report questionnaires, we assessed providers’ perceptions of the LC and the number of providers delivering IC. Nineteen of thirty-four providers (54%) reported delivering IC at the end of training and at 10-months. Providers rated the face-to-face trainings and collaborative team trainings as the most helpful LC components. Barriers to the use of the LC included lack of leadership support and the lack of ability to electronically track progress through the electronic medical record. Additional research, quality improvement, and policy changes at higher administrative levels are needed to identify methods to sustain the use of LC among providers serving homeless veterans.

Introduction: Smokers with respiratory diseases are less likely to quit than those without impaired lung function, yet few studies have investigated the effectiveness of smoking cessation interventions with this population, and none have used a computer-tailored approach.

Aims: This paper aims to fill this gap in the literature by exploring smokers’ experiences when trying to quit and their perceptions of a computer-tailored intervention.

Methods: Semi-structured interviews were conducted with 26 smokers recruited from six general practises in North London. Thematic analysis was conducted to examine participants’ previous experiences of quitting and their perceptions of receiving personal tailored feedback reports to aid smoking cessation.

Results: Participants discussed how their positive smoking experiences coupled with their negative cessation experiences led to conflicts with quitting smoking. Although the computer-tailored intervention was key in prompting quit attempts and participants valued its personal approach; it was not sufficient as a stand-alone intervention.

Conclusions: The results highlight the difficulties that smokers experience when quitting and the need for a more personalised stop smoking service in smokers with respiratory diseases. The study also demonstrates the application and potential for computer-tailored intervention as part of a wider programme of long-term smoking cessation.

Introduction: The level of smoking cessation support across UK prisons is variable, with most offering pharmacological support, such as nicotine replacement therapy. However, with a complete smoking ban in prisons in England now imminent, additional standardised behavioural support is necessary to help offenders go smoke-free.

Aims: This study used the Behaviour Change Wheel to aim to develop the content of an online smoking cessation intervention for offenders, with consideration of their capability, motivation and opportunity for behaviour change.

Methods: This was an intervention development study. The Behaviour Change Wheel was used to map cognitive, behavioural, physiological and social targets for the intervention, onto appropriate intervention techniques for inclusion in the smoking cessation programme for offenders.

Results: Psychological capability, social opportunity and reflective and automatic motivation were identified through deductive thematic analysis as areas of change required to achieve smoking cessation. A total of 27 behavioural change techniques were chosen for this smoking cessation intervention and were mapped onto the Lifestyle Balance Model which provided the theoretical basis on which the components of the programme are conceptualised. This included strategies around increasing motivation to quit, anticipating smoking triggers, modifying smoking-related thoughts, regulating emotions, managing cravings, replacing smoking and rewarding nicotine abstinence and adopting a healthier lifestyle.

Conclusions: Through the utilisation of the Behaviour Change Wheel, the development process of this digital smoking cessation intervention was achieved. Further research is planned to evaluate the clinical effectiveness of this intervention and to explore how the programme is implemented in practice within prison settings.

Despite a downwards trend in smoking prevalence, smoking remains the UK's biggest preventable cause of premature mortality. Specialist stop smoking support programmes provided by the NHS have helped to reduce smoking prevalence and whilst there has been a vast amount of research investigating the most effective behavioural and pharmacological support models, little is known about the impact of smoking cessation advisor's smoking status and clinical effectiveness on quit rates. This study aimed to identify factors that contribute to NHS stop smoking advisor performance using a quantitative cross-sectional design via an online survey that was completed by 159 participants in 24 London boroughs. Multiple regression analyses revealed that level of training, years practiced, level of advisor education, number of patients supported in a given year, and smoking status had no significant impact on NHS stop smoking advisor quit rate in this sample. However, the model revealed that proportion of time spent delivering smoking cessation support was significantly associated with quit rate. It is imperative that this finding is considered when recruiting, commissioning, and training new smoking cessation advisors or provider organisations.

Introduction: Telephone quitlines are an easily accessible and effective means for delivering cessation services including nicotine replacement therapy (NRT). Varenicline (VAR) may show superior quit rates to NRT, but has not been routinely evaluated in the context of quitlines.

Aims: To assess the feasibility of distributing VAR through a quitline, and preliminarily compare cessation rates between participants receiving VAR and NRT.

Methods: Participants were recruited through the New York State Smokers’ Quitline. Those randomised to VAR (n = 200) were instructed to obtain a prescription from their primary care physician (PCP) to be filled by mail through the research pharmacy. Those randomised to NRT (n = 100) were mailed NRT using an existing protocol. Outcome measures were number of submitted prescriptions and dispensed medication kits, and self-reported 7-day point prevalence abstinence at follow-up.

Results: The research pharmacy filled 100% of prescriptions through the quitline. However, only 27% of the VAR Arm submitted a prescription. An intent-to-treat analysis revealed that those receiving NRT were more likely to be abstinent at follow-up than the VAR Arm (OR, 2.42; 95% CI, 1.27–4.60; p < 0.01). The per-protocol analysis, which only included those in the VAR Arm who submitted a prescription, showed no difference in quit rates.

Conclusions: The present protocol resulted in successful delivery of VAR through the quitline, but a sizable proportion of the VAR Arm did not submit a prescription. Self-reported barriers included being unable to obtain a prescription from a PCP. Future studies should explore alternative methods for delivering VAR through quitlines.

Introduction: Many barriers exist to integrating smoking cessation into delivery of lung cancer screening including limited provider time and patient misconceptions.

Aims: To demonstrate that proactive outreach from a telephone counsellor outside of the patient's usual care team is feasible and acceptable to patients.

Methods: Smokers undergoing lung cancer screening were approached for a telephone counselling study. Patients agreeing to participate in the intervention (n = 27) received two telephone counselling sessions. A 30-day follow-up evaluation was conducted, which also included screening participants receiving usual care (n = 56).

Results/Findings: Most (89%) intervention participants reported being satisfied with the proactive calls, and 81% reported the sessions were helpful. Use of behavioural cessation support programs in the intervention group was four times higher (44%) compared to the usual care group (11%); Relative Risk (RR) = 4.1; 95% CI: 1.7 to 9.9), and seven-day abstinence in the intervention group was double (19%) compared to the usual care group (7%); RR = 2.6; 95% CI: 0.8 to 8.9).

Conclusions: This practical telephone-based approach, which included risk messages clarifying continued risks of smoking in the context of screening results, suggests such messaging can boost utilisation of evidence-based tobacco treatment, self-efficacy, and potentially increase the likelihood of successful quitting.

Introduction: The emergence of electronic cigarettes (ECs) has become a growing phenomenon that has sharply split opinion among the public health community, physicians, and lawmakers.

Aims: We sought to determine chest physician perceptions regarding ECs.

Methods: We conducted a web-based survey of 18,000 American College of Chest Physician (CHEST) members to determine health care provider experiences with EC users and to characterise provider perceptions regarding ECs.

Results/Findings: There were 994 respondents. Eighty-eight per cent reported that patients had asked their opinion of ECs, and 31% reported EC use among at least 10% of their patients. More disagreed than agreed (41% vs. 21%) that patients could improve their health by switching from tobacco smoking to daily EC use. Respondents were split on whether ECs promote tobacco cessation (32% agree vs. 33% disagree).

Conclusions: Current perceptions of ECs are variable among providers. More than 1/3 of respondents felt that EC's could be used for smoking cessation for smokers who failed prior quit attempts with approved therapies. However, many respondents were not convinced that ECs will reduce harms from tobacco use. There is an urgent need to generate additional high quality scientific data regarding ECs to inform chest physicians, health professionals, and the general public.

Aims: This study aimed to evaluate pharmacists’ and physicians’ perception and knowledge of e-cigarettes, including comfort level in counselling patients on these products. The study also assessed if, and to what extent, patient e-cigarette usage is collected as a marker of tobacco use status.

Methods: Surveys were distributed to community pharmacists and family practice physicians for 3 months, and responses were analysed utilising descriptive and inferential statistics.

Results: The majority of respondents reported not feeling fully confident on counselling patients about e-cigarettes, and responses revealed gaps in knowledge in both groups. Mixed results were obtained on the inclusion of e-cigarettes in assessment of patient smoking status.

Conclusions: Pharmacists and physicians would benefit from further information on e-cigarettes. Due to the increasing popularity, healthcare professionals will be called upon to serve as, care providers and informational resources to patients who use these products. This survey provided a consensus that further steps should be taken to increase product training and information dissemination.

Introduction: Higher levels of anxiety and depression have been found to be associated with greater difficulty in stopping smoking. This raises the question as to whether mood disturbance may be associated with exposure to, and use of, quitting support.

Aims: This study examined whether General Practitioner (GP) advice and/or offer of support, or stop-smoking service use differed between smokers reporting or not reporting depression/anxiety.

Methods: Data came from the Smoking Toolkit Study. Participants were 1,162 English adults who reported currently smoking or having stopped within the past 12 months, aged 40+ years, surveyed between April and September 2012. Anxiety/depression was assessed by the mood disturbance item of the EuroQol five dimensions questionnaire (EQ-5D). This was compared to recall of GP quit advice and/or support, and stop-smoking aid use adjusting for age, gender, and social grade.

Results/Findings: Smokers reporting depression/anxiety were more likely to recall being offered advice and support to stop smoking by their GP (OR = 1.50, 95% C.I. = 1.05–2.13). However, there were no significant differences in use of stop-smoking aids during the past year.

Conclusions: Smokers reporting depression/anxiety are more likely to be offered stop-smoking support by their GPs, but this does not appear to translate into stop-smoking aid use, despite high motivation to quit. Given higher nicotine dependence in this group, mental health specific support may need to be offered, and more needs to be done to make this offer of aid attractive.

Introduction: The majority of attempts to stop smoking end in failure. One way to improve success may be to explore different combinations of existing cessation medications.

Aims: This observational study examined ‘triple therapy’ (varenicline + nicotine patch + nicotine lozenge) in 36 smokers trying to quit.

Methods: A 12-week, observational study exploring tolerability, via adverse events (AEs) elicited at each of nine phone assessments. Secondary outcomes included satisfaction rates, medication changes and self-reported quit rates at week 12.

Results: Thirty five of thirty six participants reported at least one AE. Insomnia (75%), abnormal dreams (72%) and nausea (64%) were most common. Most were mild to moderate. No deaths, hospitalisations, cardiovascular events or suicidality were reported. Six participants (17%) decreased the dose of at least one medication, 5 (14%) decreased the dose then discontinued at least one medication and 13 (36%) discontinued at least one medication without trying a lesser dose. Participants were highly satisfied with their medications, and 58% reported quitting at 12 weeks, with 38% reporting prolonged abstinence.

Conclusions: Despite high rates of AEs and medication changes, high rates of satisfaction and self-reported quitting, with no serious AEs, were observed with triple therapy. Additional data on tolerability and efficacy are needed.

Trial Registration:Clinicaltrials.gov number NCT02681510.

Introduction: We characterised tobacco use, cessation patterns, and patient satisfaction with a cessation support program at an NCI Designated Comprehensive Cancer Center following a mandatory tobacco assessment and automatic referral.

Methods: A 3-month follow-up survey (via web, paper, or telephone) was administered between March 2013 and November 2013 for all patients referred to and contacted by a cessation support service, and who consented to participation three months prior to administration. Patients were asked about their perceived importance and self-efficacy to quit smoking, quit attempts, and satisfaction with the cessation service.

Results: Fifty-two percent (257/499) of patients who participated in the cessation support service, and consented to be contacted again, completed a follow-up survey. Of those who participated, 9.7% were referred to the service as having recently quit tobacco (in the past 30 days) and 23.6% reported having quit at the time of first contact. At the 3-month follow-up, 48.1% reported being smoke-free for the previous seven days. When patients were asked about their experience with the cessation service, 86.4% reported being very or mostly satisfied with the service, and 64.3% reported that their experience with the service increased their satisfaction with the care received at the cancer centre.

Conclusions: Our findings suggest that recently diagnosed cancer patients are aware that quitting tobacco is important, are making attempts to quit, and are amenable to an opt-out automatic referral cessation support service as part of their cancer care.

This study examined the role of social support and behavioural interventions used during the last unsuccessful quit attempt for smokers’ intentions to quit smoking within the next six months, and identified smokers’ attributes associated with the use of social support and behavioural interventions. The analytic sample included 7,195 adult daily smokers who responded to the 2010–2011 Tobacco Use Supplement to the Current Population Survey, conducted in the United States, and indicated having a serious quit attempt in the past 12 months. Smokers who relied on social support from friends and family had higher odds of intending to quit than those who did not (OR = 1.39, 95% CI = 1.22:1.58), and smokers who used interventions had higher odds of intending to quit than those who did not (OR = 1.36, 95% CI = 1.07:1.74). These associations were similar for both sexes, all age groups, and nicotine dependence levels. Both, relying on social support and the use of behavioural interventions were more common among smokers who were female, higher educated, residing in the Western US region, and those who used pharmacological aids for smoking cessation. Social support and behavioural interventions are associated with higher intentions to quit among attempters who relapsed and thus, may aid future smoking cessation.

Introduction: Smoking before and during pregnancy is a risk for women and their babies, but encouraging tobacco abstinence challenges practitioners.

Aims: We define correlates of tobacco use around pregnancy and determine the impact of providers’ efforts to encourage abstinence.

Methods: We analysed responses (2000 – 2010) from the Pregnancy Risk Assessment Monitoring System questionnaire for Maine, United States, a state with higher than average smoking rates. We performed multivariable logistic regression analysis with demographic and behavioural independent variables, and smoking in the last 3 months before and in the last 3 months of pregnancy as dependent variables.

Results: Of 12,409 questionnaire responders, 32% smoked before pregnancy; 60.5% of these women continued during pregnancy. Women were more likely to smoke before pregnancy and to continue during pregnancy if they had a previous birth, were unmarried, had ≤ a high school education, or had a household income ≤ $20,000/year. Pre-pregnancy smokers were more likely to continue smoking during pregnancy if their gestational weight gain was less than recommended and, surprisingly, if they recalled a provider discussion about smoking cessation.

Conclusions: We identify women at risk for smoking before and during pregnancy and demonstrate that current tobacco abstinence interventions by providers may not always be effective.

Introduction: Waterpipe use is a significant health concern in low- and middle-income countries like Viet Nam, yet there is a lack of research on factors that may influence use and self-efficacy to quit among adults.

Aims: This study examined the relationship between social norms related to waterpipe use and self-efficacy to quit among male waterpipe smokers in Viet Nam.

Methods: A cross-sectional survey was conducted with 214 adult male waterpipe smokers enrolled in a large cluster–randomised controlled trial conducted in a rural province in Viet Nam. Associations between social norms related to waterpipe smoking and the participants’ confidence to quit waterpipes were assessed using hierarchical regression models to account for differences among study sites and other covariates.

Results: Self-efficacy to quit smoking was positively associated with immediate family members’ not minding participants smoking and with extended family's encouragement to quit smoking.

Conclusions: The findings suggest the need for a more comprehensive understanding of the functions and characteristics of the social context of waterpipe smoking, including the social networks of waterpipe smokers, to inform effective cessation interventions for waterpipe smokers.

Introduction: Adherence to transdermal nicotine patches, one of the most popular and effective treatments for nicotine dependence, remains very low and is a strong predictor of cessation rates.

Aims: This study examined individual factors related to adherence as well as differences over time between adherent (>85% of daily patch use) and non-adherent participants (<85% of daily patch use).

Methods: We analysed data from 440 participants who received 8 weeks of 21 mg transdermal nicotine and four behavioural counselling sessions within an effectiveness trial that examined the effects of long-term treatment. Multiple logistical regression assessed baseline variables associated with patch adherence and generalised estimating equations (GEE) were used to evaluate changes in craving and withdrawal, depressive and anxiety symptoms, substitute and complementary reinforcers, and side effects between participants who were or were not adherent.

Results: Adherence to patch use was strongly associated with smoking cessation at week 8 (p < 0.05). In a logistic regression model, being female, living with a child or children, and higher self-reported anxiety symptoms were predictive of lower patch adherence (p < 0.05). In the GEE analysis, adherence was significantly associated with a greater reduction in craving, a greater engagement in substitute reinforcers, and a greater decrease in complementary reinforcers over time (p < 0.05).

Conclusions: Difficulties adhering to transdermal nicotine patches may be related to psychiatric comorbidity, difficulty managing nicotine craving, and challenges with engaging in substitute reinforcers and reducing exposure to complementary reinforcers. These constructs may serve as targets for interventions designed to increase treatment adherence.
