Impact of self-initiated pre-quit smoking reduction on cessation rates: results of a clinical trial of smoking cessation among female prisoners

ObjectivesThis study examined differences in cessation success based on smokers' self-initiated pre-quit reductions in cigarettes per day (cpd).MethodsThe study utilized data from a nicotine replacement + behavioral therapy smoking cessation intervention conducted in a female prison facility with 179 participants who were wait-listed for 6 months prior to intervention. We compared two groups of smokers based on whether they self-selected to reduce smoking prior to their cessation attempt (n = 77) or whether they increased smoking or did not reduce (n = 102). General Estimating Equations (GEE) were used to model smoking cessation through 12-month follow-up.ResultsExamination of pre-cessation cpd showed that those who reduced were heavier smokers at baseline, relative to those who did not reduce (p < 0.001). By the week prior to the quit attempt (week 3) heavier smokers at baseline smoked significantly fewer cigarettes (p < 0.001) and had lower CO levels (p < 0.05) compared to baseline lighter smokers. GEE analyses showed that individuals who reduced prior to their quit attempt had significantly higher quit rates during early treatment but these gains were not sustained by follow-up points.ConclusionsParticipant-initiated pre-cessation smoking reduction may be initially helpful in preparing to quit smoking, or may serve as a marker for participant motivation to quit smoking, but these differences do not sustain over time. More intensive interventions are still needed for successful cessation.     

Motivation to quit as a predictor of smoking cessation and abstinence maintenance among treated Spanish smokers

IntroductionAlthough quitting motivation predicts smoking cessation, there have been inconsistent findings regarding motivation predicting long-term maintenance of abstinence. Moreover, most such research has been conducted in North America and the United Kingdom. The aim of this study was to examine motivation to quit as a predictor of smoking cessation and of abstinence maintenance in a Spanish sample.MethodThe sample comprised 286 Spanish smokers undergoing psychological treatment for smoking cessation. Motivation to quit was assessed pre-treatment and post-treatment with the Readiness to Quit Ladder. Abstinence post-treatment and at 6 month follow-up was biochemically verified.ResultsParticipants with higher levels of pre-treatment and post-treatment motivation were more likely to be abstinent at the end of the treatment (OR = 1.36) and at 6 month follow-up (OR = 4.88). Among abstainers at the end of the treatment (61.9%), higher levels of motivation to quit post-treatment predicted maintaining abstinence at 6 months (OR = 2.83). Furthermore, participants who failed to quit smoking reported higher levels of motivation to quit post-treatment than they had pretreatment (p < .001).ConclusionsMotivation to quit smoking predicted short and long-term cessation, and also predicted long-term maintenance of abstinence. These results have implications for understanding motivational processes of smoking cessation in general, while extending research to Spanish smokers. They may also help in the design of cessation and relapse-prevention interventions. Specifically, the results suggest that motivational enhancement is important throughout the cessation and maintenance periods.     

Increased self-efficacy to quit and perceived control over withdrawal symptoms predict smoking cessation following nicotine dependence treatment

AimTo examine changes in nicotine withdrawal, nicotine craving, self-efficacy to quit smoking, and perceived control over withdrawal symptoms as predictors of smoking cessation following behavioral counseling and nicotine replacement therapy in a sample of smokers.Design and settingThe data were ascertained from a randomized effectiveness trial comparing nicotine patch to nicotine lozenge. Predictors of smoking cessation were assessed at baseline and 5 weeks post-baseline, and 24-hour point prevalence abstinence, biochemically confirmed, was assessed at the end-of-treatment (week 15) and 6 months after a target quit date (week 27).Participants642 treatment-seeking smokers randomized to 12 weeks of nicotine patch or nicotine lozenge.FindingsParticipants who showed a greater increase in self-efficacy to quit smoking (OR = 1.09, 95% CI: 1.02–1.16, p = .01) and perceived control over withdrawal symptoms (OR = 1.02, 95% CI: 1.00–1.04, p = .05) were significantly more likely to have quit smoking at week 15. Participants who showed a greater increase in self-efficacy to quit smoking (OR = 1.04, 95% CI: 1.01–1.06, p = .01) were significantly more likely to have quit smoking at week 27. Changes in withdrawal symptoms and craving were not related to week 15 or week 27 abstinence rates.ConclusionsThe results highlight two relatively under-studied potential psychological predictors of abstinence following treatment for nicotine dependence. Behavioral counseling interventions to promote smoking cessation should help smokers develop confidence in their ability to quit smoking and increase their sense of control over withdrawal symptoms to increase their chances for cessation.     

Predictors of tobacco abstinence in outpatient smokers with schizophrenia or bipolar disorder treated with varenicline and cognitive behavioral smoking cessation therapy

BackgroundThe estimated mortality gap between those with and without serious mental illness (SMI) is increasing, now estimated at 28 years, which is largely due to smoking-related diseases.AimsWe sought to identify predictors of 14-day continuous abstinence in stable outpatient smokers with SMI.MethodAdult smokers with schizophrenia spectrum (n = 130) or bipolar disorder (n = 23) were enrolled in a 12-week course of varenicline and cognitive-behavioral therapy for smoking cessation.ResultsIndependent predictors of abstinence included reduction in withdrawal symptoms prior to the quit day, fewer cigarettes smoked per day at baseline, better baseline attention, remitted alcohol dependence, and lower expectation of peer support to aid quitting.ConclusionsInterventions that consider these targets may improve smoking cessation outcomes in those with SMI.     

Predictors of medication adherence and smoking cessation among smokers under community corrections supervision

IntroductionIndividuals in the U.S. criminal justice system now represent over 12% of all current U.S. smokers. With smoking banned in most U.S. jails and prisons, the cessation focus for this population has shifted to individuals who are under community correction supervision (e.g., probation, parole). The aim of this study was to examine predictors of successful smoking cessation among criminal justice individuals supervised in the community.MethodsFive hundred participants under community corrections supervision were randomized to receive either four sessions of smoking cessation counseling or no counseling in conjunction with 12 weeks of bupropion treatment plus brief physician advice to quit. Logistic regression analyses examined associations of smoking variables with medication adherence and successful abstinence. Mediation analysis evaluated the indirect effects of medication adherence on smoking abstinence.ResultsThe strongest associate of medication adherence was previous use of bupropion, while the strongest associate of smoking abstinence was medication adherence. Mediation analysis indicated that previous use of bupropion indirectly increased cessation rates through the pathway of increased medication adherence.ConclusionsThese results highlight the importance of medication adherence for smoking cessation among community corrections smokers. Providing exposure to medication may be a promising intervention to increase medication adherence and subsequent cessation rates in this population.     

Effectiveness of a small cash incentive on abstinence and use of cessation aids for adult smokers: A randomized controlled trial

BackgroundLarge amount of financial incentive was effective to increase tobacco abstinence, but the effect of small amount is unknown.PurposeWe evaluated if a small amount of cash incentive (HK$500/US$64) increased abstinence, quit attempt, and use of cessation aids.MethodsA three-armed, block randomized controlled trial recruited 1143 adult daily smokers who participated in the Hong Kong “Quit to Win” Contest. Biochemically validated quitters of the early-informed (n = 379, notified about the incentive at 1-week and 1-month follow-up) and the late-informed incentive group (n = 385, notified at 3-month follow-up) received the incentive at 3 months. The validated quitters of the control group (n = 379) received the incentive at 6 months without prior notification. All subjects received brief advice, a self-help education card and a 12-page booklet. The outcomes were self-reported 7-day point prevalence of abstinence, quit attempt (intentional abstinence for at least 24 h) and use of cessation aids at 3-month follow-up.ResultsBy intention-to-treat, the early-informed group at 3-month follow-up reported a higher rate of quit attempt (no smoking for at least 24 h) than the other 2 groups (44.1% vs. 37.4%, Odds ratio (OR) = 1.32, 95% CI 1.03–1.69, p = 0.03), but they had similar abstinence (9.2% vs. 9.7%, OR = 0.95, 95% CI 0.62, 1.45). The early- and late-informed group showed similar quitting outcomes. The early-informed group reported more quit attempts by reading self-help materials than the other 2 groups (31.4% vs. 25.3%, OR = 1.56, 95% CI 1.12–2.18, p < 0.01).ConclusionsThe small cash incentive with early notification increased quit attempt by “self-directed help” but not abstinence. Future financial incentive-based programmes with a larger incentive, accessible quitting resources and encouragement of using existing smoking cessation services are needed.     

Engagement and abstinence among users of a smoking cessation text message program for veterans

BackgroundSmokefreeVET is a text messaging smoking cessation program available to veterans enrolled in the Veterans Health Administration. SmokefreeVET was developed in collaboration with the National Cancer Institute as part of the SmokefreeTXT initiative.PurposeTo evaluate the real world use of and effectiveness of the SmokefreeVET program for SmokefreeVET users who enrolled between 2013 and 2014.MethodsDemographics and smoking behavior of 1470 SmokefreeVET users who enrolled between 2013 and 2014 were analyzed. Latent growth mixture modeling was used to identify discrete classes of SmokefreeVET users based on engagement patterns. Multi-level modeling determined class differences in abstinence.ResultsThe average age of the SmokefreeVET user was 48, 75% of users were male, and 84% were daily smokers. After five weeks, 13% of all users reported abstinence from smoking. Five statistically distinct engagement classes of SmokefreeVET users were identified. Highly engaged classes were significantly less likely to opt-out and more likely to report abstinence. Over 60% of users who were classified as high engagers throughout the program reported abstinence 5 weeks after their quit date. Users were more likely to report abstinence after two weeks if they used smoking cessation medication than those that did not use medication (OR = 9.01, p < 0.001).ConclusionsSmokefreeVET may be effective at supporting abstinence among a real world group of highly engaged users. Smoking cessation medication use was also associated with abstinence in SmokefreeVET users. Engagement appears to be a critical component when assessing the efficacy of a text messaging smoking cessation intervention.     

Motivational interviewing and the decisional balance procedure for cessation induction in smokers not intending to quit

IntroductionThe decisional balance (DB) procedure examines the pros and cons of behavior change and was considered a component in early formulations of Motivational Interviewing (MI). However, there is controversy and conflicting findings regarding the use of a DB exercise within the treatment of addictions and a need to clarify the role of DB as a component of MI.MethodsCollege tobacco smokers (N = 82) with no intentions on quitting were randomly assigned to receive a single counseling session of either Motivational Interviewing using only the decisional balance component (MIDB), or health education around smoking cessation (HE). Assessments were obtained at baseline, immediately post-treatment, 1 week, and 4 weeks.ResultsCompared to HE, the MIDB sessions scored significantly higher on the Motivational Interviewing Treatment Integrity (MITI) scale (all standardized differences d > 1, p < 0.001). Unexpectedly, self-report Pros of smoking scores increased for MIDB but decreased for HE (MIDB vs HE standardized difference d = 0.5; 95%CI 0.1 to 1.0, p = 0.021). Both groups showed significant reductions in smoking rates and increases in motivation to quit, quit attempts, and self-reported abstinence, with no significant group differences. Changes in the Pros of smoking were correlated with MITI scores, but not with cessation outcomes. In contrast, increases in the Cons of smoking and therapeutic alliance were predictive of better cessation outcomes.ConclusionsThe decisional balance exercise as formulated by earlier versions of MI may be counter-productive and cautions around its use are warranted. Instead, improved cessation outcomes appear associated with increasing perceived benefits of quitting and positive therapeutic alliance.     

Trends in self-efficacy to quit and smoking urges among homeless smokers participating in a smoking cessation RCT

IntroductionIn the U.S., approximately 73% of homeless adults smoke cigarettes and they experience difficulty quitting. Homeless smokers report low self-efficacy to quit and that smoking urges are a barrier to quitting. Self-efficacy to quit and smoking urges are dynamic and change throughout smoking cessation treatment. This study examines changes in self-efficacy to quit and smoking urges throughout a smoking cessation intervention among the homeless and identifies predictors of change in these characteristics.MethodsHomeless smokers (n = 430) participating in a smoking cessation randomized controlled trial in the U.S. completed surveys at baseline, and weeks 1, 2, 4, 6, 8, and 26 on demographic and smoking characteristics (i.e., confidence to quit, self-efficacy to refrain from smoking, and smoking urges). A growth curve analysis was conducted by modeling change in the smoking characteristics over time and examining the variability in the change in smoking characteristics by demographic characteristics and treatment group.ResultsAmong the full sample, self-efficacy to refrain from smoking increased linearly over time, confidence to quit increased until the midpoint of treatment but subsequently decreased, and smoking urges decreased until the midpoint of treatment but subsequently increased. There were race differences in these trajectories. Racial minorities experienced significantly greater increases in self-efficacy to refrain from smoking than Whites and Blacks had higher confidence to quit than Whites.ConclusionsWhite participants experienced less increase in self-efficacy to refrain from smoking and lower confidence to quit and therefore may be a good target for efforts to increase self-efficacy to quit as part of homeless-targeted smoking cessation interventions. Sustaining high confidence to quit and low smoking urges throughout treatment could be key to promoting higher cessation rates among the homeless.     

Reducing alcohol consumption to minimize weight gain and facilitate smoking cessation among military beneficiaries

IntroductionSmoking cessation-related weight gain can have significant negative health and career consequences for military personnel. Alcohol reduction combined with smoking cessation may decrease weight gain and relapse.MethodA randomized clinical trial of military beneficiaries compared a standard smoking cessation (i.e., brief informational) intervention (N = 159), with a brief motivational smoking cessation intervention that emphasized reduced drinking to lessen caloric intake and minimize weight gain (N = 158).ResultsParticipants who received the motivational intervention were significantly more likely to quit smoking at the 3-month follow-up (p = 0.02), but the differences were not maintained at 6 (p = 0.18) or 12 months (p = 0.16). Neither weight change nor alcohol reduction distinguished the 2 groups. Smoking cessation rates at 12 months (motivational group = 32.91%, informational group = 25.79%) were comparable to previous studies, but successful cessation was not mediated by reduced drinking.ConclusionsAlcohol reduction combined with smoking cessation did not result in decreased weight gain or improved outcomes.     

Reasons for quitting smoking in young adult cigarette smokers

BackgroundAlthough most young adult smokers want to quit smoking, few can do so successfully. Increased understanding of reasons to quit in this age group could help tailor interventions, but few studies document reasons to quit in young adults or examine reasons to quit by smoker characteristics.MethodsIn 2011–12, 311 current smokers (age 22–28, M = 24.1; 48.9% male, 51.1% female; 50.4% daily smokers) from the Nicotine Dependence in Teens Study completed the Adolescent Reasons for Quitting scale. We assessed differences in the importance of 15 reasons to quit by sex, education, smoking frequency, quit attempt in the past year, perceived difficulty in quitting, and motivation to quit. We also examined differences between participants who discounted the importance of long-term health risks and those who acknowledged such risks.ResultsConcerns about getting sick or still smoking when older were considered very important by > 70% of participants. Median scores were higher among daily smokers, those who had tried to quit or who expressed difficulty quitting, and those with strong motivation to quit. Discounters (14.5% of participants) were primarily nondaily, low-consumption smokers. Their Fagerström Test for Nicotine Dependence scores did not differ from non-discounters', and 11% (vs. 35.7% of non-discounters) were ICD-10 tobacco dependent.ConclusionsNovel smoking cessation interventions are needed to help young adult smokers quit by capitalizing on their health concerns. Discounters may need educational intervention to better understand the impact of even “light” smoking on their health before or in conjunction with quit interventions.     

Motivational interviewing versus brief advice for cigarette smokers in residential alcohol treatment

Residential treatment for substance use disorders (SUD) provides opportunity for smoking intervention. A randomized controlled trial compared: (1) motivational interviewing (MI) to brief advice (BA), (2) in one session or with two booster sessions, for 165 alcoholics in SUD treatment. All received nicotine replacement (NRT). MI and BA produced equivalent confirmed abstinence, averaging 10% at 1 month, and 2% at 3, 6 and 12 months. However, patients with more drug use pretreatment (> 22 days in 6 months) given BA had more abstinence at 12 months (7%) than patients in MI or with less drug use (all 0%). Boosters produced 16–31% fewer cigarettes per day after BA than MI. Substance use was unaffected by treatment condition or smoking cessation. Motivation to quit was higher after BA than MI. Thus, BA plus NRT may be a cost-effective way to reduce smoking for alcoholics with comorbid substance use who are not seeking smoking cessation.     

Dependence and motivation to stop smoking as predictors of success of a quit attempt among smokers seeking help to quit

IntroductionIt is not known how well motivation to stop smoking predicts abstinence in a clinical sample relative to the most widely used measure of cigarette dependence.MethodsA secondary analysis was conducted from a trial with 864 smokers making quit attempt. Fagerström Test of Cigarette Dependence (FTCD), Heaviness of Smoking Index (HSI), and motivation to stop smoking (composite of determination to quit and importance of quitting) were measured at baseline. Continuous smoking abstinence, validated by expired-air carbon monoxide, was assessed at 4 weeks, 6 months and 12 months post-quit date. FTCD, HSI, non-HSI items in FTCD, and motivation were assessed as predictors of abstinence.ResultsIn multiple-logistic regressions, controlling for age, gender and medication use, lower scores for FTCD, HSI and non-HSI all significantly predicted abstinence at all follow-ups, while motivation did not predict abstinence at any time. Likelihood ratio tests showed that the FTCD contributed most to the model at 4 weeks and 6 months; at 12 months FTCD and non-HSI equally contributed most to the model. At 4 weeks and 6 months, predictions were improved by combining HSI and non-HSI components, compared with using these components alone.ConclusionsCigarette dependence, measured by the FTCD, or by its HSI or non-HSI components, predicts both short-term and medium-term outcomes of attempts to stop smoking in treatment-seeking smokers involved in a clinical trial, whereas strength of motivation to stop predicts neither. Both the HSI and non-HSI components may be considered as briefer alternatives to the full FTCD.     

Emotion dysregulation explains the relation between insomnia symptoms and negative reinforcement smoking cognitions among daily smokers

IntroductionInsomnia co-occurs with smoking. However, mechanisms that may explain their comorbidity are not well known.MethodThe present study tested the hypothesis that insomnia would exert an indirect effect on negative reinforcement smoking processes via emotion dysregulation among 126 adult non-treatment seeking daily smokers (55 females; M_age = 44.1 years, SD = 9.72). Negative reinforcement smoking processes included negative reinforcement smoking outcome expectancies, negative reinforcement smoking motives, and two negative expectancies from brief smoking abstinence (somatic symptoms and harmful consequences).ResultsInsomnia symptoms yielded a significant indirect effect through emotion dysregulation for negative reinforcement smoking outcome expectancies, negative reinforcement smoking motives, and harmful consequences expectancies from brief smoking abstinence. In contrast to prediction, however, insomnia was not associated with somatic symptom expectancies from brief smoking abstinence through emotion dysregulation.ConclusionsThese data may suggest that the indirect effect of emotion dysregulation is more relevant to cognitive-affective negative reinforcement processes rather than somatic states. Overall, the present findings contribute to a growing body of literature linking emotion dysregulation as an explanatory mechanism for insomnia and smoking and uniquely extend such work to an array of clinically significant negative reinforcement smoking processes.     

Combined treatment for at-risk drinking and smoking cessation among Puerto Ricans: A randomized clinical trial

Tobacco and alcohol use are linked behaviors that individually and synergistically increase the risk for negative health consequences. This study was a two-group, randomized clinical trial evaluating the efficacy of a behavioral intervention, “Motivation And Problem Solving Plus” (MAPS +), designed to concurrently address smoking cessation and the reduction of at-risk drinking. Targeted interventions may promote coaction, the likelihood that changing one behavior (smoking) increases the probability of changing another behavior (alcohol use). Puerto Ricans (N = 202) who were smokers and at-risk drinkers were randomized to standard MAPS treatment focused exclusively on smoking cessation (S-MAPS), or MAPS +, focused on cessation and at-risk drinking reduction. Drinking outcomes included: number of at-risk drinking behaviors, heavy drinking, binge drinking, and drinking and driving. MAPS + did not have a significant main effect on reducing at-risk drinking relative to S-MAPS. Among individuals who quit smoking, MAPS + reduced the number of drinking behaviors, the likelihood of meeting criteria for heavy drinking relative to S-MAPS, and appeared promising for reducing binge drinking. MAPS + did not improve drinking outcomes among individuals who were unsuccessful at quitting smoking. MAPS + showed promise in reducing at-risk drinking among Puerto Rican smokers who successfully quit smoking, consistent with treatment enhanced coaction. Integrating an alcohol intervention into cessation treatment did not reduce engagement in treatment, or hinder cessation outcomes, and positively impacted at-risk drinking among individuals who quit smoking. Findings of coaction between smoking and drinking speak to the promise of multiple health behavior change interventions for substance use treatment and chronic disease prevention.     

Impact of quitting smoking and smoking cessation treatment on substance use outcomes: An updated and narrative review

BackgroundHistorically, smoking cessation was thought to negatively impact substance use outcomes among smokers who use other substances. We sought to synthesize recent reports on this association.MethodsGoogle Scholar, PubMed, and Cinahl were searched for studies published from 2006 to March 29, 2016 that reported impact of smoking cessation treatment or quitting smoking on substance use or substance use disorder treatment outcomes in the general population and among those in substance abuse treatment. Studies were grouped by reported impact as follows: “positive” (i.e. improved), “null” (i.e. no change), or “negative” (i.e. worsened).ResultsTwenty-four studies were included. Eighteen reported the impact of quitting smoking and six reported the impact of smoking cessation treatment intervention, independent of quitting, on substance use outcomes. Eleven studies (46%) reported solely positive impact; four (17%) reported solely null impact; eight (33%) reported mixed positive and null impact by analysis (combined and subgroup, n = 1); substance (n = 4); length of follow-up (n = 2); and comparison group (n = 1). One study (4%) reported mixed negative and null impact by ethnic group. No studies reported increased substance use.ConclusionSmoking cessation does not appear to have a negative effect, and often has a positive effect on substance use outcomes. Smoking cessation advice should be offered, without hesitation, to smokers who report substance use and those in treatment for substance use disorder.     

E-cigarette advertisements,and associations with the use of e-cigarettes and disapproval or quitting of smoking: Findings from the International Tobacco Control (ITC) Netherlands Survey

BackgroundMuch attention has been directed towards the possible effects of e-cigarette advertisements on adolescent never smokers. However, e-cigarette advertising may also influence perceptions and behaviours of adult smokers. The aim of our study was to examine whether noticing e-cigarette advertisements is associated with current use of e-cigarettes, disapproval of smoking, quit smoking attempts, and quit smoking success.MethodsWe used longitudinal data from two survey waves of the ITC Netherlands Survey among smokers aged 16 years and older (n = 1198). Respondents were asked whether they noticed e-cigarettes being advertised on television, on the radio, and in newspapers or magazines in the previous 6 months.ResultsThere was a significant increase in noticing e-cigarette advertisements between 2013 (13.3%) and 2014 (36.0%), across all media. The largest increase was for television advertisements. There was also a substantial increase in current use of e-cigarettes (from 3.1% to 13.3%), but this was not related to noticing advertisements in traditional media (OR = 0.99, p = 0.937). Noticing advertisements was bivariately associated with more disapproval of smoking (Beta = 0.05, p = 0.019) and with a higher likelihood of attempting to quit smoking (OR = 1.37, p = 0.038), but these associations did not reach significance in multivariate analyses. There was no significant association between noticing advertisements and quit smoking success in either the bivariate or multivariate regression analysis (OR = 0.92, p = 0.807).ConclusionNoticing e-cigarette advertisements increased sharply in the Netherlands between 2013 and 2014 along with increased e-cigarette use, but the two appear unrelated. The advertisements did not seem to have adverse effects on disapproval of smoking and smoking cessation.     

Systematic review of social media interventions for smoking cessation

BackgroundPopular social media could extend the reach of smoking cessation efforts. In this systematic review, our objectives were: 1) to determine whether social media interventions for smoking cessation are feasible, acceptable, and potentially effective; 2) to identify approaches for recruiting subjects; and 3) to examine the specific intervention design components and strategies employed to promote user engagement and retention.MethodsWe searched Scopus, Medline, EMBASE, Cochrane Central, PsychINFO, CINAHL, and Web of Science through July 2016 and reference lists of relevant articles. Included studies described social media interventions for smoking cessation and must have reported outcomes related to feasibility, acceptability, usability, or smoking-related outcomes.ResultsWe identified 7 studies (all were published since 2014) that enrolled 9755 participants (median = 136 [range 40 to 9042]). Studies mainly used Facebook (n = 4) or Twitter (n = 2), and emerged as feasible and acceptable. Five studies reported smoking-related outcomes such as greater abstinence, reduction in relapse, and an increase in quit attempts. Most studies (n = 6) recruited participants using online or Facebook advertisements. Tailored content, targeted reminders, and moderated discussions were used to promote participant engagement. Three studies found that active participation through posting comments or liking content may be associated with improved outcomes. Retention ranged from 35% to 84% (median = 70%) across the included studies.ConclusionsOur review highlights the feasibility, acceptability and preliminary effectiveness of social media interventions for smoking cessation. Future research should continue to explore approaches for promoting user engagement and retention, and whether sustained engagement translates to clinically meaningful smoking cessation outcomes.     

Is smokeless tobacco use becoming more common among U.S. male smokers? Trends in Alaska

IntroductionThe tobacco industry has promoted the use of smokeless tobacco (SLT) to smokers as a substitution for cigarettes when smoking is not possible, and some smokers are using SLT this way. However, few publications have examined recent trends in dual cigarette and SLT use (dual use) over time in the U.S.Materials and methodsWe examined trends in the use of SLT among current, former and never cigarette smokers using data on adult (aged 18+ years) males (n = 16,590) from the 1996–2008 Alaska Behavioral Risk Factor Surveillance System (BRFSS). We also examined trends from 2004 to 2008 in cigarette consumption among dual users.ResultsBetween 1996 and 2008, the overall prevalence of current SLT use and prevalence of current smoking among Alaskan men did not significantly change over time (p-value from age-adjusted models p = .63, p = .09, respectively). When we examined trends in SLT use by smoking status, we found that the prevalence of current SLT use remained unchanged between 1996 and 2008 among former and never smokers, but almost doubled among current smokers (age-adjusted p = .004). Between 2004 and 2008, cigarette consumption remained steady among current smokers who did not use SLT, but significantly decreased among dual users (age-adjusted p < .001).ConclusionsOur findings suggest that male smokers in Alaska are increasingly likely to use SLT, but do not appear to be switching to SLT use exclusively. We recommend that other state tobacco control programs examine trends in dual use to confirm our findings, and for programs to continue encouraging cessation of all tobacco products.
