Quit attempt correlates among smokers by race/ethnicity

Smoking cessation interventions for Hispanic/Latino(a) adults in the USA: protocol for a systematic review and planned meta-analysis

INTRODUCTION

Hispanic smokers face multiple cultural and socioeconomic barriers to cessation that lead to prominent health disparities, including a lack of language-appropriate, culturally relevant, evidence-based smoking cessation interventions. This systematic review will examine the literature on smoking cessation interventions for Hispanic adults in the USA to assess (1) the availability of interventions, (2) the methodological quality of the studies evaluating the interventions and (3) the efficacy of the interventions.

METHODS AND ANALYSIS

A systematic literature search will be conducted, in English with no date limits, through the following databases starting at year of inception: Medical Allied Health Literature, Embase, American Psychology Association Psychology Articles, Cumulative Index to Nursing and Allied Health Literature Complete, ScienceDirect, Health & Medicine Collection and Web of Science Core Collection. Trial registries and grey literature sources will be searched to identify ongoing or unpublished studies. Literature search will be rerun prior to eventual submission of the review to ensure the inclusion of relevant studies. Quantitative studies evaluating the efficacy of a smoking cessation intervention (ie, smoking cessation as a measured outcome) for Hispanic adult smokers in the USA will be included in the systematic review. Two authors will independently identify relevant studies, extract data and conduct quality and risk of bias assessments. Discrepancies in coding will be discussed between the two reviewers and pending disagreements will be resolved by a third reviewer. First, the quality of all studies will be assessed, then randomised controlled trials (RCTs) will be further evaluated for risk of bias using Cochrane's Risk of Bias Tool. All eligible studies will be summarised descriptively. If data allow, the efficacy of smoking cessation interventions tested in RCTs, with a minimum follow-up of 6 months, will be quantitatively estimated using ORs and 95% CIs. The association between intervention type/modality and efficacy will be assessed via subgroup analyses.

A genetic association study of tobacco withdrawal endophenotypes in African Americans

Genome-wide association (GWA) genetic epidemiology research has identified several variants modestly associated with brief self-report smoking measures, predominately in European Americans. GWA research has not applied intensive laboratory-based measures of smoking endophenotypes in African Americans-a population with disproportionately low quit smoking rates and high tobacco-related disease risk. This genetic epidemiology study of non-Hispanic African Americans tested associations of 89 genetic variants identified in previous GWA research and exploratory GWAs with 24 laboratory-derived tobacco withdrawal endophenotypes. African American cigarette smokers (N = 528; ≥10 cig/day; 36.2% female) completed two counterbalanced visits following either 16-hr of tobacco deprivation or ad libitum smoking. At both visits, self-report and behavioral measures across six unique "sub-phenotype" domains within the tobacco withdrawal syndrome were assessed (Urge/Craving, Negative Affect, Low Positive Affect, Cognition, Hunger, and Motivation to Resume Smoking). Results of the candidate variant analysis found two significant small-magnitude associations. The rs11915747 alternate allele in the CAD2M gene region was associated with .09 larger deprivation-induced changes in reported impulsivity (0-4 scale). The rs2471711alternate allele in the AC097480.1/AC097480.2 gene region was associated with 0.26 lower deprivation-induced changes in confusion (0-4 scale). For both variants, associations were opposite in direction to previous research. Individual genetic variants may exert only weak influences on tobacco withdrawal in African Americans. Larger sample sizes of non-European ancestry individuals might be needed to investigate both known and novel loci that may be ancestry-specific.

Effect of socioeconomic status on smoking cessation behavior in selected African countries: Secondary analysis of Global Adult Tobacco Survey data (2014–2018)

Introduction

Tobacco use remains a global public health challenge. While studies report that smoking cessation reduces the risk of cancer and other NCDs, evidence is scarce in African region on socio-economic determinants of smoking cessation behavior. This study examined the socio-economic differentials of smoking cessation behavior among smokers in four African countries.

Methods

The study was conducted through secondary analysis of Global Adult Tobacco Survey (GATS) data from four African countries (Ethiopia, Kenya, Senegal and Tanzania). Smoking cessation behavior was assessed using two variables i) intention to quit smoking in next 12 months and ii) previous quit attempts made within 12 months preceding the survey. The weighted percentages for intention to quit smoking and previous quit attempts were computed. The adjusted odds ratios were computed using multinomial logistic regression to identify the association between socio-economic factors and smoking cessation behavior.

Results

Across the four countries studied, the previous quit attempts among smokers were in the range of 39.6% to 53.7%. Around 7.6% to 15.8% of the smokers tried to quit with an assistance. In Ethiopia over 76.5% of current smokers reported no intention to quit in next 12 months after survey, whereas the same was 50.4% in Senegal. While country specific differences were observed, females, those belonging to the poorest wealth index, unemployed and those without any formal education reported significantly lower odds of previous quit attempts or having an intention to quit smoking.

Conclusion

The socio-economic vulnerabilities were found to compromise smoking cessation behavior among the smokers in countries studied. Targeted interventions, adherence to smokefree laws, and provision of cessation support are essential to improve quit rates and mitigate tobacco risks among socio-economically vulnerable population.

Factors that Predict Smoking Cessation among Older Koreans: Based on the Korea National Health and Nutrition Examination Survey 2016-2018

Background

Tobacco smoking is associated with several diseases and deaths in older Koreans. This study aimed to evaluate the factors associated with smoking cessation in older Koreans.

Methods

We selected 579 subjects who started smoking before the age of 65 years from the Korea National Health and Nutrition Examination Survey 2016–2018. We excluded the subjects who quit smoking before the age of 65 years, and then categorized the rest of subjects into those who stopped smoking after the age of 65 years and those who are constant smokers. Multivariable logistic analysis was performed to evaluate the factors related to smoking cessation among older Koreans.

Results

Among the participants, 66.1% were persistent smokers. After multivariable analysis, the factors significantly associated with smoking cessation were as follows: being in the age group of 75–79 years (adjusted odds ratio [aOR], 4.07; 95% confidence interval [CI], 2.12–7.83), being in the age group of 70–74 years (aOR, 3.10; 95% CI, 1.72–5.61), a family history of ischemic heart disease (aOR, 3.36; 95% CI, 1.09–10.35), and having had no cancer screening (aOR, 0.36; 95% CI, 0.18–0.70).

Conclusion

Further efforts to identify the factors related to smoking cessation will help formulate a smoking cessation policy.

Alternative Tobacco Product Use and Smoking Quit Attempts Among Teenagers in the United States: A Cross-Sectional Study

Background

Public health interventions have heightened awareness of risk factors and ill effects of tobacco use. Though sales of conventional tobacco products have been steadily declining, there is the advent of a new generation of alternative tobacco products marketed with claims of reduced harms and smoking cessation aids. These products are increasing in prevalence and popularity among adolescents.

Aim

The aim of this study is to assess the prevalence of tobacco quit attempts in adolescents in the United States and examine its relationship to the use and self-reported awareness of two alternative tobacco products: e-cigarettes and heated tobacco products (HTPs).

Methods

This is a cross-sectional analysis of data (2,271) from the 2019 National Youth Tobacco Survey (NYTS) of middle and high school students in the United States. Logistic regression analysis was employed to determine the odds of tobacco quit attempts adjusting for age, race, gender, school type, and household tobacco exposure.

Results

The overall prevalence of tobacco quit attempts among e-cigarette users and HTP users was 52.50% and 5.20%, respectively. Results of multivariate regression analyses identified age (OR=0.74, 95% CI:0.57-0.96), race (OR=1.41, 95% CI:1.14-1.75), and household tobacco smoke exposure (OR=1.19, 95% CI:1.01-1.39) as the main factors that are significantly associated with tobacco quit attempts adjusting for all other covariates.

Conclusion

This study did not show a statistically significant association between the awareness and use of e-cigarettes, and heated tobacco products and tobacco smoking quit attempts. Race, age, and exposure to household tobacco smoking were positively associated with quit attempts. Further studies are needed to clarify whether the use and awareness of e-cigarettes and HTPs are associated with tobacco smoking quit attempts within the US adolescent population.

Assessing the evidence on the differential impact of menthol versus non-menthol cigarette use on smoking cessation in the U.S. population: a systematic review and meta-analysis

Background

The potential impact of menthol versus non-menthol cigarette use on smoking behaviors is an intensely scrutinized topic in the public health arena. To date, several general literature reviews have been conducted, but findings and conclusions have been discordant. This systematic review followed PRISMA guidelines to examine the Key Question, “Does menthol cigarette use have a differential impact on smoking cessation compared with non-menthol cigarette use?”

Methods

Six databases—Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, Database of Abstracts of Reviews of Effects, MEDLINE, Embase and PsycInfo—were queried from inception to June 12, 2020. Articles comparing menthol versus non-menthol cigarette smokers in terms of at least one predefined smoking cessation outcome were included. Risk of bias was assessed using the Agency for Healthcare Research and Quality Evidence-Based Practice Center approach. A random-effects model utilizing the DerSimonian and Laird method to pool adjusted odds ratio was applied. Variations among pooled studies were assessed using Cochran’s Q statistic, and heterogeneity was quantified using the inconsistency index (I²).

Results

Forty-three demographically adjusted studies (22 rated “good”, 20 rated “fair”, and one study rated “poor” individual study quality) comparing menthol and non-menthol smokers were qualitatively synthesized across the following measures (study count; strength of evidence): duration of abstinence (2; low); quit attempts (15; insufficient); rate of abstinence/quitting (29; moderate); change in smoking quantity/frequency (5; insufficient); and, return to smoking/relapse (2; insufficient). Overall, the qualitative synthesis failed to show a consistent trend for an association between menthol cigarette use and smoking cessation across outcomes. Meta-analyses found no difference between menthol and non-menthol cigarette use and either quit attempts or abstinence.

Conclusions

Given the lack of consistency or statistical significance in the findings—combined with a “low” overall strength of evidence grade, based on deficiencies of indirectness and inconsistency—no consistent or significant associations between menthol cigarette use and smoking cessation were identified. Recommendations for future studies include increased focus on providing longitudinal, adjusted data collected from standardized outcome measures of cessation to better inform long-term smoking cessation and menthol cigarette use. Such improvements should also be further considered in more methodologically rigorous systematic reviews characterized by objectivity, comprehensiveness, and transparency with the ultimate objective of better informing public health and policy decision making.

Longitudinal pathways of exclusive and polytobacco cigarette use among youth, young adults and adults in the USA: findings from the PATH Study Waves 1-3 (2013-2016)

OBJECTIVE

Cigarettes are the most harmful and most prevalent tobacco product in the USA. This study examines cross-sectional prevalence and longitudinal pathways of cigarette use among US youth (12-17 years), young adults (18-24 years) and adults 25+ (25 years and older).

DESIGN

Data were drawn from the first three waves (2013-2016) of the Population Assessment of Tobacco and Health Study, a nationally representative, longitudinal cohort study of US adults and youth. Respondents with data at all three waves (youth, N=11 046; young adults, N=6478; adults 25+, N=17 188) were included in longitudinal analyses.

RESULTS

Among Wave 1 (W1) any past 30-day (P30D) cigarette users, more than 60%, persistently used cigarettes across three waves in all age groups. Exclusive cigarette use was more common among adult 25+ W1 P30D cigarette users (62.6%), while cigarette polytobacco use was more common among youth (57.1%) and young adults (65.2%). Persistent exclusive cigarette use was the most common pathway among adults 25+ and young adults; transitioning from exclusive cigarette use to cigarette polytobacco use was most common among youth W1 exclusive cigarette users. For W1 youth and young adult cigarette polytobacco users, the most common pattern of use was persistent cigarette polytobacco use.

CONCLUSIONS

Cigarette use remains persistent across time, regardless of age, with most W1 P30D smokers continuing to smoke at all three waves. Policy efforts need to continue focusing on cigarettes, in addition to products such as electronic nicotine delivery systems that are becoming more prevalent.

Assessment of Racial Differences in Pharmacotherapy Efficacy for Smoking Cessation: Secondary Analysis of the EAGLES Randomized Clinical Trial

Importance

Understanding Black vs White differences in pharmacotherapy efficacy and the underlying reasons is critically important to reducing tobacco-related health disparities.

Objective

To compare pharmacotherapy efficacy and examine variables to explain Black vs White differences in smoking abstinence.

Design, Setting, and Participants

This study is a secondary analysis of the Evaluating Adverse Events in a Global Smoking Cessation Study (EAGLES) double-blind, placebo-controlled, randomized clinical trial, which took place at clinical trial centers, academic centers, and outpatient clinics in 29 states in the US. US Black and White smokers who smoked 10 or more cigarettes per day with and without psychiatric comorbidity were enrolled between November 2011 and January 2015. Data analysis was performed from July 2019 to January 2020.

Interventions

Participants were randomized (1:1:1:1) in a double-blind, triple-dummy, placebo- and active-controlled (nicotine patch) trial of varenicline and bupropion for 12 weeks with follow-up through week 24.

Main Outcomes and Measures

Biochemically verified continuous cigarette abstinence rate (CAR) from weeks 9 to 24. Baseline, postbaseline treatment, and safety characteristics were examined as variables to explain race differences in abstinence.

Results

Of the 1065 Black smokers enrolled, 255 were randomized to receive varenicline, 259 received bupropion, 286 received nicotine replacement therapy (NRT [ie, nicotine patch]), and 265 received placebo. Among the 3044 White smokers enrolled, 778 were randomized to receive varenicline, 769 received bupropion, 738 received NRT, and 759 received placebo. Participants were predominantly female (614 Black [57.7%] and 1786 White [58.7%] women) and heavy smokers (mean [SD] cigarettes per day, 18.2 [7.9] for Black and 20.0 [7.5] for White smokers), with a mean (SD) age of 47.2 (11.2) years for Black and 46.5 (12.7) years for White participants. Treatment and race were associated with CAR for weeks 9 to 24. The CAR was 4.9% lower for Black vs White participants (odds ratio [OR], 0.53; 95% CI, 0.41-0.69; P < .001); differences were found across all treatments. Pooling psychiatric and nonpsychiatric cohorts, varenicline (OR, 2.63; 95% CI, 1.90-3.63; P < .001), bupropion (OR, 1.75; 95% CI, 1.25-2.46; P = .001), and NRT (OR, 1.52; 95% CI, 1.07-2.16; P = .02) had greater efficacy than placebo for White participants. Only varenicline (OR, 2.63; 95% CI, 1.26-5.48; P = .01) had greater efficacy than placebo for Black participants. Baseline, postbaseline, and safety characteristics differed by race, but these variables did not eliminate the association of race with CAR. Black participants had 49% reduced odds of CAR for weeks 9 to 24 compared with White participants in the adjusted model (OR, 0.51; 95% CI, 0.39-0.66; P < .001).

Conclusions and Relevance

Black and White smokers achieved the highest rate of abstinence while taking varenicline, suggesting that it is the best first-line therapy for these groups. However, Black smokers were less responsive to all therapies, including placebo. Understanding variables (eg, socioeconomic or biological) beyond those may lead to improved treatment outcomes for Black smokers.

Widening disparities in cigarette smoking by race/ethnicity across education level in the United States

Reducing tobacco use is an important public health objective. It is the largest preventable cause of death and disease, yet inequalities remain. This study examines combined educational and racial/ethnic disparities in the United States related to cigarette smoking for the three largest racial/ethnic groups (African Americans, Hispanics/Latinos, and non-Hispanic Whites). Data included nine Tobacco Use Supplements to the Current Population Surveys (TUS-CPS) conducted in the United States from 1992/1993-2018 for four smoking metrics: ever smoking rates, current smoking rates, consumption (cigarettes per day), and quit ratios. Across all TUS-CPS samples, there were 9.5% African Americans, 8.8% Hispanics/Latinos, and 81.8% non-Hispanic Whites who completed surveys. Findings revealed that lower educational attainment was associated with increased ever and current smoking prevalence over time across all racial/ethnic groups, and education-level disparities within each race/ethnicity widened over time. Disparities in ever and current smoking rates between the lowest and highest categories of educational attainment (less than a high school education vs. completion of college) were larger for African Americans and non-Hispanic Whites than Hispanics/Latinos. Non-Hispanic Whites had the highest cigarette consumption across all education levels over time. College graduates had the highest quit ratios for all racial/ethnic groups from 1992 to 2018, with quit ratios significantly increasing for Hispanics/Latinos and non-Hispanic Whites, but not African Americans. In conclusion, educational disparities in smoking have worsened over time, especially among African Americans and Hispanics/Latinos. Targeted tobacco control efforts could help reduce these disparities to meet public health objectives, although racial/ethnic disparities may persist regardless of educational attainment.

Effects of Current and Enhanced Tobacco Corrective Messages on Smokers' Intention to Quit Smoking and Intention to Purchase Cigarettes

INTRODUCTION

A federal court has ordered tobacco companies to issue corrective messages to address tobacco-related misperceptions. This study examined the effects of viewing current versus two enhanced versions of tobacco corrective messages on smokers' intention to quit smoking and intention to purchase cigarettes.

METHODS

US adult smokers (N = 803) were randomly assigned to view (1) two current tobacco corrective messages (Current), (2) two corrective messages that include an industry deception statement (Industry Deception), or (3) two corrective messages with an industry deception statement and testimonials of people harmed by smoking (Industry Deception + Testimonial). Outcomes were pretest-posttest change in intentions to quit smoking and posttest intention to purchase cigarette measures.

RESULTS

Intention to quit smoking increased significantly after viewing the Current corrective messages versus baseline. In addition, viewing the Industry Deception + Testimonial messages increased intention to quit smoking compared with the Current corrective condition and the Industry Deception condition. Hispanic smokers had increased intention to quit smoking and decreased intention to purchase cigarettes to a greater degree than non-Hispanic smokers in response to Industry Deception + Testimonial messages. There was no significant difference in intention to purchase cigarettes across conditions.

CONCLUSIONS

Enhancing the current corrective statements by including an industry deception statement and testimonials may strengthen effects and contribute to remedying the effects of tobacco misinformation.

IMPLICATIONS

Previous research has found that draft or proposed versions of tobacco industry corrective messages are effective in correcting beliefs and knowledge. However, studies have not examined how the current court-ordered corrective messages could change intention to quit smoking and intention to purchase cigarettes nor whether enhanced messages could perform better. Study findings suggest that the current corrective messages can increase smokers' intention to quit smoking beyond their baseline intention. More importantly, enhancing corrective messages by including an industry deception statement and testimonial was found to be more effective than current corrective messages. Findings can inform future iterations of tobacco correctives and strategies to reverse the effects of tobacco misinformation.

The differential impact of nicotine replacement therapy sampling on cessation outcomes across established tobacco disparities groups

Cigarette smoking is increasingly concentrated among marginalized populations with limited access to evidence-based cessation treatment. This includes racial/ethnic minorities, lower income individuals, those with lower educational attainment, and residents of rural areas. To reach Healthy People 2020 objectives, successful cessation interventions must narrow these disparities. Nicotine replacement therapy (NRT) sampling is an easily translatable and scalable intervention that could enhance treatment access and thus narrow disparities. The present study examined individual-level demographic moderators of the impact of NRT sampling on cessation-related behaviors including: 1) use of a cessation medication, 2) making a 24-hour quit attempt, 3) floating abstinence, and 4) 7-day point prevalence abstinence at 6-months. Study participants included N = 1245 adult smokers enrolled in the Tobacco Intervention in Primary Care Treatment Opportunities for Providers (TIP TOP) study, a recently concluded large-scale clinical trial of NRT sampling relative to standard care within 22 primary care clinics across South Carolina. Generalized linear models examined individual-level demographic moderators of treatment effect. Results suggest that NRT sampling may be more effective among some of the most disadvantaged groups of smokers, including smokers with lower income and education, as well those who live in more rural areas. The effects of NRT sampling did not differ by race. In sum, NRT sampling is a low-cost, low-burden intervention that could be disseminated broadly to reach large numbers of smokers and potentially narrow cessation disparities.

Factors That Explain Differences in Abstinence Between Black and White Smokers: A Prospective Intervention Study

BACKGROUND

Black-white differences in smoking abstinence are not well understood. This trial sought to confirm previously reported differences in quitting between blacks and whites and to identify factors underlying this difference.

METHODS

During enrollment, 224 black and 225 white low-income smokers were stratified on race and within race on age and sex to ensure balance on these factors known to impact abstinence. The intervention included varenicline for 12 weeks and six guideline-based smoking cessation counseling sessions. The primary endpoint was cotinine-verified 7-day point prevalence smoking abstinence at week 26. A priori socioeconomic, smoking, treatment process (eg, treatment utilization, side effects, withdrawal relief), psychosocial, and biological factors were assessed to investigate race differences in abstinence. Unadjusted odds ratios (OR) were used to compare abstinence between blacks and whites. Adjusted odds ratios from logistic regression models were used to examine predictors of abstinence. All statistical tests were two-sided.

RESULTS

Blacks were less likely to achieve abstinence at week 26 (14.3% vs 24.4%, OR = 0.51, 95% confidence interval [CI] = 0.32 to 0.83, P = .007). Utilizing best subsets logistic regression, five factors associated with race jointly predicted abstinence: home ownership (yes/no, OR = 3.03, 95% CI = 1.72 to 5.35, P < .001), study visits completed (range = 0-6, OR = 2.81, 95% CI = 1.88 to 4.20, P < .001), income (household member/$1000, OR = 1.03, 95% CI = 1.01 to 1.06, P = .02), plasma cotinine (per 1 ng/mL, OR = 0.997, 95% CI = 0.994 to 0.999, P = .002), and neighborhood problems (range = 10-30, OR = 0.88, 95% CI = 0.81 to 0.96, P = .003).

CONCLUSIONS

The race difference in abstinence was fully explained by lack of home ownership, lower income, greater neighborhood problems, higher baseline cotinine, and higher visit completion, which were disproportionately represented among blacks. Findings illuminate factors that make it harder for blacks in the United States to quit smoking relative to whites and provide important areas for future studies to reduce tobacco-related health disparities.

On providing smoking cessation services in alcohol and other drug treatment settings: Results from a U.S. national survey of attitudes among recovering persons

BACKGROUND

Nicotine addiction through cigarette use is highly prevalent among individuals suffering from alcohol and other drug (AOD) problems and remains a prominent risk factor for morbidity, mortality, and healthcare utilization. Whereas most people agree that providing smoking cessation services (SCS) to this vulnerable population is vitally important, the timing of such service provision has been hotly debated, including whether such services should be excluded, available (but not offered), offered, or fully integrated into AOD treatment settings. Important stakeholders in this debate are those in recovery from AOD problems who, in addition to having often been AOD treatment patients themselves, frequently hold influential clinical, research or policy positions and thus can influence the likelihood of SCS provision. This study sought to understand the attitudes of this important stakeholder group in providing SCS in AOD treatment settings.

METHOD

We assessed a national cross-sectional sample of individuals in recovery from an AOD problem (n = 1973) on whether SCS should be: a. excluded; b. available; c. offered; or d. integrated into AOD services. We estimated associations between participants' demographic, clinical, and recovery support service use history, and SCS attitude variables, using multinomial logistic regression.

RESULTS

Roughly equal proportions endorsed each attitudinal position (23.5% excluded, 25% available, 24.6% offered; 26.9% integrated). Correlates of holding more positive SCS implementation attitudes were Black race; primary substance other than alcohol, greater intensity of former or recent smoking, and less mutual-help organization participation; older individuals achieving recovery between 30 and 40 years ago also had more positive attitudes toward integrating SCS.

CONCLUSIONS

About half of those sampled were either against SCS inclusion in AOD settings or were in favor of making it "available" only, but not in offering it or integrating it. This oppositional pattern was accentuated particularly among those with primary alcohol problem histories and those participating in mutual-help organizations. Given the universally well-known negative health effects of smoking, understanding more about the exact reasons why certain groups of recovering persons may endorse such positions is an area worthy of further investigation, as it may uncover potential barriers to SCS implementation in AOD treatment settings.

Factors associated with tobacco cessation attempts among inpatients in a psychiatric hospital

Introduction

Several effective evidence-based tobacco treatment approaches can optimize cessation attempts; however, little is known about the utilization of such strategies by people with mental illnesses (MI) during their cessation attempts.

Aims

To examine methods used during and factors associated with tobacco cessation attempts among people with MI.

Methods

Self-administered cross-sectional survey data were obtained from 132 tobacco using inpatients from a psychiatric facility in Kentucky, USA.

Results

Our study found ‘cold turkey’ as the most reported method by inpatient tobacco users with MI in their prior cessation attempts regardless of the psychiatric diagnosis category. Multivariate logistic regression found ethnicity (OR 26.1; 95% CI 2.9–237.1), age at 1st smoke (OR 1.1; 95% CI 1.0–1.1), importance to quit (OR 1.2; 95% CI 1.0–1.4), and receipt of brief tobacco treatment interventions (OR 1.1; 95% CI 1.0–1.3) significantly associated with quit attempt in the past year.

Conclusion

Despite the existence of various evidence-based approaches to enhance tobacco cessation among people with MI, ‘cold-turkey’ was the most preferred method in this sample. In addition, this study highlighted ethnicity, importance to quit, age at 1st smoke, and receipt of brief interventions as important factors to consider when tailoring tobacco cessation in this population. Though ethnicity is a non-modifiable factor, an informed provider may intervene skillfully by addressing socio-cultural barriers specific to an ethnic group. Lower ratings on the motivation ruler and early age of smoking initiation could also inform providers when using motivational interviewing and other evidence-based tobacco-cessation approaches.

A randomized controlled trial of a smoking cessation self-help intervention for Spanish-speaking Hispanic/Latinx smokers: Study design and baseline characteristics

Although the current smoking prevalence among Hispanics/Latinxs (10%) is lower than in non-Hispanic whites (15%), higher prevalence is observed among certain subgroups (e.g., Puerto Rican males, 19%). Hispanic/Latinx smokers face unique challenges such as lower awareness and acceptability of nicotine replacement aids, lower prevalence of using counseling or medication, and receiving less advice to quit by their health care providers. Despite these barriers to smoking cessation, few interventions specifically targeted to Hispanic/Latinx smokers have been developed and evaluated. This paper summarizes the design, methods, analysis plan, and sample baseline characteristics of an ongoing randomized controlled trial to assess the efficacy of a Spanish-language self-help smoking cessation intervention among Hispanics/Latinxs. Current smokers who prefer health education materials in Spanish were randomized to one of two conditions. The usual care group received a standard smoking cessation booklet developed by the National Cancer Institute. The intervention group received 10 booklets, 9 pamphlets and a booklet for family and friends mailed monthly over 18 months. All participants complete self-report surveys every 6 months over 2 years. Smoking abstinence is biochemically verified at 12- and 24-month follow-up. A total of 2387 smokers were screened, 2056 were eligible and 1417 were enrolled in the study. The primary outcome is self-reported 7-day point prevalence abstinence. If the intervention is deemed efficacious, it has potential to have a large public health impact with respect to reducing smoking rates and smoking related morbidity and mortality among a large underserved minority population.

Facilitators and barriers to smoking cessation among minority men using the behavioral-ecological model and Behavior Change Wheel: A concept mapping study

Background and aim

Universal smoking cessation strategies are not always successful for minorities, among whom smoking is highly prevalent despite high intention to quit. This study identifies facilitators for smoking cessation, as perceived by minority male smokers, that can inform a culturally appropriate national plan for smoking prevention and cessation.

Methods

We conducted in 2013 a three-stage study among Arab minority male current and former smokers (ages 18–64) in Israel, among whom smoking is very high: first, a Concept Mapping (CM) study with 102 and 202 participants in the brainstorming, and sorting and rating phases respectively. Second, we assigned clusters identified in the CM study to contingency levels using the Behavioral Ecological Model (BEM). Third, we classified clusters into intervention functions and policies using the Behavior Change Wheel (BCW).

Findings

The CM study revealed 58 barriers and facilitators for smoking prevention and cessation that were sorted into 11 clusters by the participants. These clusters were analogous to four BEM level contingency of smoking (social, institutional, community and individual). We classified it into two main policy categories, based on the BCW: 1- restructuring the socio-political environment of smoking through affirmative government's policies towards Arab minority in Israel, and 2-developing a culturally appropriate plan for smoking cessation in Arab local authorities including: raising awareness about tobacco hazards; enforcing anti-smoking laws; strengthening community institutional action; providing smoking cessation services; considering raising prices for tobacco products, addressing psychological sources of smoking in Arab men.

Conclusions

Our study revealed barriers, facilitators and contingencies of smoking prevention and cessation with two main policy action items among the Arab minority in Israel: changing the socio-political environment of smoking, and developing a culturally appropriate smoking prevention and cessation national plan. Our study framework can inform policies and culturally appropriate interventions for smoking prevention and cessation in other minorities.

Correlates of attempting to quit smoking among adults in Bangladesh

Background

Quit attempts are very essential in population-based smoking cessation. Little is known about the correlates of making a quit attempt of smoking in Bangladesh. We aimed to examine correlates of making a quit attempt of smoking among adults in Bangladesh.

Methods

We used data from the 2009 Global Adult Tobacco Survey, Bangladesh. A total of 2217 adult current smokers (2141 males and 76 females) aged 15 years and older who participated in the survey were included. We compared socio-demographic, behavioral, motivational, knowledge and attitudes towards smoking, quitting methods utilized, use of social media to quit smoking, and environmental characteristics of current smokers who made an attempt to quit with those who made no quit attempt during the previous 12 months of the survey. We applied multivariable logistic regression models for analyzing the data.

Results

Among the 2217 current smokers, 1058 (47.72%) made attempt to quit. We found respondents who smoked their first cigarette within 6 to 30 min of waking up were more likely to make an attempt to quit than those who smoked their first cigarette within 5 min of waking. Moreover, among daily current smokers who smoked 10–19 manufactured cigarettes per day were less likely to make a quit attempt. We also found intention to quit smoking, smoking rules inside the home, and exposure to anti-smoking advertisements as significant correlates of making a quit attempt of smoking among adults in Bangladesh.

Conclusions

Policymakers should consider our findings when implementing tobacco control programs in Bangladesh.

•

Quit attempts are very essential in population-based smoking cessation.

•

Among the 2233 current smokers, 1058 individuals attempted to quit smoking.

•

Smokers who don't smoke quickly after waking were more likely to make quit attempt.

Smokers who lived in a smoke-free home were also more likely to make quit attempt.

Menthol cigarettes and the public health standard: a systematic review

Background

Although menthol was not banned under the Tobacco Control Act, the law made it clear that this did not prevent the Food and Drug Administration from issuing a product standard to ban menthol to protect public health. The purpose of this review was to update the evidence synthesis regarding the role of menthol in initiation, dependence and cessation.

Methods

A systematic review of the peer-reviewed literature on menthol cigarettes via a PubMed search through May 9, 2017. The National Cancer Institute’s Bibliography of Literature on Menthol and Tobacco and the FDA’s 2011 report and 2013 addendum were reviewed for additional publications. Included articles addressing initiation, dependence, and cessation were synthesized based on study design and quality, consistency of evidence across populations and over time, coherence of findings across studies, and plausibility of the findings.

Results

Eighty-two studies on menthol cigarette initiation (n = 46), dependence (n = 14), and cessation (n = 34) were included. Large, representative studies show an association between menthol and youth smoking that is consistent in magnitude and direction. One longitudinal and eight cross-sectional studies demonstrate that menthol smokers report increased nicotine dependence compared to non-menthol smokers. Ten studies support the temporal relationship between menthol and reduced smoking cessation, as they measure cessation success at follow-up.

Conclusions

The strength and consistency of the associations in these studies support that the removal of menthol from cigarettes is likely to reduce youth smoking initiation, improve smoking cessation outcomes in adult smokers, and in turn, benefit public health.

Perceived Effectiveness of Antismoking Ads and Association with Quit Attempts Among Smokers: Evidence from the Tips From Former Smokers Campaign

BACKGROUND

Measures of perceived effectiveness (PE) of ads have been validated to predict changes in cognitive precursors of quit attempts, but a relationship between PE and actual quit attempts has not been shown in population-based studies. We analyzed smokers' PE ratings of ads from the national Tips From Former Smokers (Tips) campaign to (1) establish the validity of PE in predicting quit attempts in a large, nationally representative sample of smokers; (2) identify behavioral and demographic correlates of PE among respondents; and (3) examine whether PE is influenced by matching the race/ethnicity of ad participants with that of the ad viewer.

METHODS

We used survey data from two waves (baseline and follow-up) of a longitudinal online cohort of adult U.S. cigarette smokers. Respondents were shown one or more of 14 Tips campaign ads and were asked to assess each ad in terms of PE. We used multivariate models to estimate the association between baseline PE and prospective quit attempts; cross-sectional associations between PE and various respondent characteristics, including race/ethnicity, desire to quit, and health conditions; and the association between race/ethnicity of respondents and Tips ad participants.

RESULTS

Higher PE at baseline was associated with increased odds of a quit attempt at follow-up. Higher PE scores were associated with non-Hispanic black race, Hispanic ethnicity, higher desire to quit, presence of a chronic health condition, and presence of a mental health condition. There was no relationship between PE scores and matched race/ethnicity of the respondent and Tips ad participants.

CONCLUSIONS

This is the first study to demonstrate an association between PE scores for antismoking ads and prospective quit attempts in a large, nationally representative sample of smokers. Our findings also provide strong evidence that racial/ethnic minority subpopulations, including non-Hispanic blacks and Hispanics, react more favorably to Tips campaign ads irrespective of race/ethnicity of the ad participant. This suggests that message characteristics (e.g., graphic visuals and emotional content) may play a more important role in PE than race/ethnicity of ad participants.

Smoking transitions in a sample of Hispanic daily light and intermittent smokers

Few studies have documented the differences between daily light (DLS; ≤10 cigarettes per day) and intermittent (ITS; nondaily) smokers. The primary aim of this study was to assess the potential transitions (i.e., increased/stayed at same level) between baseline and a 3month follow-up of Hispanic DLS and ITS who were randomly assigned to a control group of a brief cessation intervention. Additionally, potential nicotine addiction differences between groups of smokers (e.g., ITS who became DLS vs. those who did not change) were assessed. Participants were 190 Hispanic DLS/ITS (who represent a subsample from a larger dataset, n=370) with complete data (53.7% female; Mage=38.6years, SD=15.1; range=18-74years) randomized to the control arm of a brief cessation intervention. Participants completed sociodemographics, tobacco use history, and the Fagerström Test for Nicotine Dependence (FTND; Heatherton, Kozlowski, Frecker and Fagerström, 1991). The majority of participants remained DLS (41.1%) or ITS (21.6%). ANCOVA findings indicated significant group differences regarding FTND scores (F [5114]=6.93, p<0.001). Those who remained DLS had significantly higher FTND scores than those who remained ITS and those who converted from ITS to DLS. Within these DLS/ITS who were randomized to a control group, smoking transitions primarily remained stable over time, particularly among DLS (who demonstrated higher nicotine dependence), suggesting the need for low level cessation interventions to continue and include a focus on dependence symptoms.

Increasing reach by offering choices: Results from an innovative model for statewide services for smoking cessation

Although state quitlines provide free telephone counseling and often include nicotine replacement therapy (NRT), reach remains limited (1-2% in most states). More needs to be done to engage all smokers in the quitting process. A possible strategy is to offer choices of cessation services through quitlines and to reduce registration barriers. In March 2014, ClearWay Minnesota^SM implemented a new model for QUITPLAN® Services, the state's population-wide cessation services. Tobacco users could choose the QUITPLAN® Helpline or one or more Individual QUITPLAN® Services (NRT starter kit, text messaging, email program, or quit guide). The program website was redesigned, online enrollment was added, and a new advertising campaign was created and launched. In 2014-2015, we evaluated whether these changes increased reach. We also assessed quit attempts, quit outcomes, predictors of 30-day abstinence, and average cost per quit via a seven-month follow-up survey. Between March 2014-February 2015, 15,861 unique tobacco users registered, which was a 169% increase over calendar year 2013. The majority of participants made a quit attempt (83.7%). Thirty-day point prevalence abstinence rates (responder rates) were 26.1% for QUITPLAN Services overall, 29.6% for the QUITPLAN Helpline, and 25.5% for Individual QUITPLAN Services. Several variables predicted quit outcomes, including receiving only one call from the Helpline and using both the Helpline and the NRT starter kit. Providing greater choice of cessation services and reducing registration barriers have the potential to engage more tobacco users, foster more quit attempts, and ultimately lead to long-term cessation and reductions in prevalence.

An Examination of the Ethnicity-Specific Prevalence of and Factors Associated with Substance Use and Misuse: Cross-Sectional Analysis of Croatian and Bosniak Adolescents in Bosnia and Herzegovina

Substance use and misuse (SUM) in adolescence is a significant public health problem and the extent to which adolescents exhibit SUM behaviors differs across ethnicity. This study aimed to explore the ethnicity-specific and gender-specific associations among sports factors, familial factors, and personal satisfaction with physical appearance (i.e., covariates) and SUM in a sample of adolescents from Federation of Bosnia and Herzegovina. In this cross-sectional study the participants were 1742 adolescents (17–18 years of age) from Bosnia and Herzegovina who were in their last year of high school education (high school seniors). The sample comprised 772 Croatian (558 females) and 970 Bosniak (485 females) adolescents. Variables were collected using a previously developed and validated questionnaire that included questions on SUM (alcohol drinking, cigarette smoking, and consumption of other drugs), sport factors, parental education, socioeconomic status, and satisfaction with physical appearance and body weight. The consumption of cigarettes remains high (37% of adolescents smoke cigarettes), with a higher prevalence among Croatians. Harmful drinking is also alarming (evidenced in 28.4% of adolescents). The consumption of illicit drugs remains low with 5.7% of adolescents who consume drugs, with a higher prevalence among Bosniaks. A higher likelihood of engaging in SUM is found among children who quit sports (for smoking and drinking), boys who perceive themselves to be good looking (for smoking), and girls who are not satisfied with their body weight (for smoking). Higher maternal education is systematically found to be associated with greater SUM in Bosniak girls. Information on the associations presented herein could be discretely disseminated as a part of regular school administrative functions. The results warrant future prospective studies that more precisely identify the causality among certain variables.

Cancer Outcomes in Hispanics/Latinos in the United States: An Integrative Review and Conceptual Model of Determinants of Health

Cancer is the leading cause of death among Hispanics. Compared to non-Hispanic Whites, Hispanics are more likely to be diagnosed with advanced stages of disease and experience poor quality of life following a cancer diagnosis. Cancer outcomes are influenced by a confluence of social, cultural, behavioral and biological factors. Yet, much of the behavioral and psychosocial research in oncology has focused on non-Hispanic Whites, thus limiting our understanding of the potential web of factors that can influence cancer-related outcomes among Hispanics. Furthermore, features of Hispanic ethnicity and culture may influence and interact with, social, psychosocial, health care, disease-specific, and medical factors known to influence cancer-related outcomes, yet very few studies have integrated Hispanic cultural processes when addressing cancer-related outcomes for this ethnic group. Guided by the extant literature in oncology, Hispanic culture and health, and previously established models of determinants of minority health, we present a conceptual model that highlights the interplay of social, cultural, psychosocial, disease-specific, health care, and medical factors as determinants of cancer outcomes (morbidity, mortality, quality of life) and review key evidence of how features of Hispanic culture may influence cancer outcomes and contribute to the disparate outcomes observed in Hispanic cancer samples relative to non-Hispanic Whites. Finally, we conclude with a discussion of future research opportunities and existing challenges to researching oncology outcomes among Hispanics.

Socioeconomic Inequalities in Smoking and Smoking Cessation Due to a Smoking Ban: General Population-Based Cross-Sectional Study in Luxembourg

This study aimed to measure changes in socioeconomic inequalities in smoking and smoking cessation due to the 2006 smoking ban in Luxembourg. Data were derived from the PSELL3/EU-SILC (Panel Socio-Economique Liewen Zu Letzebuerg/European Union--Statistic on Income and Living Conditions) survey, which was a representative survey of the general population aged ≥16 years conducted in Luxembourg in 2005, 2007, and 2008. Smoking prevalence and smoking cessation due to the 2006 smoking ban were used as the main smoking outcomes. Two inequality measures were calculated to assess the magnitude and temporal trends of socioeconomic inequalities in smoking: the prevalence ratio and the disparity index. Smoking cessation due to the smoking ban was considered as a positive outcome. Three multiple logistic regression models were used to assess social inequalities in smoking cessation due to the 2006 smoking ban. Education level, income, and employment status served as proxies for socioeconomic status. The prevalence of smoking decreased by 22.5% between 2005 and 2008 (from 23.1% in 2005 to 17.9% in 2008), but socioeconomic inequalities in smoking persisted. Smoking prevalence decreased by 24.2% and 20.2% in men and women, respectively; this difference was not statistically significant. Smoking cessation in daily smokers due to the 2006 smoking ban was associated with education level, employment status, and income, with higher percentages of quitters among those with a lower socioeconomic status. The decrease in smoking prevalence after the 2006 law was also associated with a reduction in socioeconomic inequalities, including differences in education level, income, and employment status. Although the smoking ban contributed to a reduction of such inequalities, they still persist, indicating the need for a more targeted approach of smoke-free policies directed toward lower socioeconomic groups.

Differences in Quit Attempts and Cigarette Smoking Abstinence Between Whites and African Americans in the United States: Literature Review and Results From the International Tobacco Control US Survey

INTRODUCTION

While cigarette smoking prevalence is declining among US adults, quit rates may differ between white and African American smokers. Here, we summarize the literature on smoking cessation behaviors in whites and African Americans across four study designs and report the findings of new analyses of International Tobacco Control (ITC) US Survey cohort data.

METHODS

We reviewed 32 publications containing 39 relevant analyses that compared quit attempts and abstinence between US whites and African Americans. Two additional longitudinal analyses were conducted on 821 white and 76 African American cigarette smokers from Waves 7 and 8 of the ITC US Survey (mean follow-up = 19 months).

RESULTS

Of 17 total analyses of quit attempts, nine (including the ITC US Survey) observed that African American smokers were more likely than whites to attempt to quit during a given year; seven found no differences. Whites were more likely than African Americans to be abstinent in five of six retrospective cohort analyses and in two of five considered community- and population-based cohort studies. Four of these 11 analyses, including one from the ITC US Survey, found no differences.

CONCLUSIONS

Of 11 population- or community-based analyses, all seven that found significant differences indicated that whites were more likely to quit than African Americans. These findings, combined with the similar results from population-based birth cohort analyses, support the conclusion that white smokers are more likely to quit than African American smokers. Efforts to encourage and support quitting among all tobacco users remain a priority.

IMPLICATIONS

This article provides a review of the literature on smoking cessation among African American and white smokers, and adds new analyses that compare quit attempts and abstinence between US African Americans and whites. Results demonstrate a clear distinction between the findings of cross-sectional and retrospective cohort studies with those of cohort studies. Reasons for these differences merit further study.

Patterns of nicotine dependence in four Eastern European countries

BACKGROUND

Evidence of patterns of nicotine dependence, although crucial for developing and implementing effective tobacco control strategies, is limited in the Eastern European countries. The purpose of this study was to evaluate the correlates of high nicotine dependence among adults in Poland, Romania, the Russian Federation and Ukraine.

METHODS

The data used in the current analysis is available from the Global Adult Tobacco Survey (2009-2011). Nicotine dependence was assessed using the Heaviness of Smoking Index (HSI), which covers two measures: reported cigarettes smoked per day and time to the first cigarette upon waking. Based on a six-point scale of HSI, nicotine dependence was categorized into low to moderate (score 0-3), and high dependence (score 4-6). Out of 31,936 completed interviews, we used data from 8229 daily smokers.

RESULTS

The study results indicate that more than 25 % of daily smokers were highly dependent on nicotine. Higher odds of high nicotine dependence were identified for males (OR = 1.5 in Poland and Romania, OR = 2.7 in Russia; p ≤ 0.001), people between 50-59 years of age (the highest odds in Romania; OR = 4.8; p ≤ 0.001) and those who had started smoking at a young age (the highest odds in Romania, OR = 5.0; p ≤ 0.001). Having fewer restrictions on smoking at home was significantly associated with a high level of nicotine dependence (the highest odds in Romania, OR = 3.0; p ≤ 0.001). A high proportion of the participants had no interest in quitting smoking, with a statistically significantly higher percentage observed among smokers highly dependent on nicotine compared to the less addicted (p ≤ 0.01).

CONCLUSIONS

Smokers highly dependent on nicotine constitute a quarter of the Romanian group of daily smokers and even more in the remaining three analyzed countries. Similar patterns of nicotine dependence were observed in all of the investigated countries showing that male gender, younger age at the smoking onset, and fewer restrictions on smoking at home were significantly associated with higher nicotine dependence. The study highlighted the fact that a high proportion of the participants had no interest in quitting smoking. These results underscore importance of policy measures as well as prevention and cessation interventions for smokers who are highly dependent on nicotine, which need to take into account the social gradient in smoking patterns.

The Relations Between False Positive and Negative Screens and Smoking Cessation and Relapse in the National Lung Screening Trial: Implications for Public Health

INTRODUCTION

Lung screening is an opportunity for smoking cessation and relapse prevention, but smoking behaviors may differ across screening results. Changes in smoking were evaluated among 18 840 current and former smokers aged 55-74 scheduled to receive three annual lung screenings.

METHODS

Participants were randomized to low-dose computed tomography or single-view chest radiography in the American College of Radiology/National Lung Screening Trial. Outcome measures included point and sustained (6-month) abstinence and motivation to quit among smokers; and relapse among smokers who quit during follow-up, recent quitters (quit < 6 months), and long-term former smokers (quit ≥ 6 months).

RESULTS

During five years of follow-up, annual point prevalence quit rates ranged from 11.6%-13.4%; 48% of current smokers reported a quit attempt and 7% of long-term former smokers relapsed. Any false positive screening result was associated with subsequent increased point (multivariable hazard ratio HR = 1.23, 95% CI = 1.13, 1.35) and sustained (HR = 1.28, 95% CI = 1.15, 1.43) abstinence among smokers. Recent quitters with ≥1 false positive screen were less likely to relapse (HR = 0.72, 95% CI = 0.54, 0.96). Screening result was not associated with relapse among long-term former smokers or among baseline smokers who quit during follow-up.

CONCLUSIONS

A false positive screen was associated with increased smoking cessation and less relapse among recent quitters. Consistently negative screens were not associated with greater relapse among long-term former smokers. Given the Affordable Care Act requires most health plans to cover smoking cessation and lung screening, the impact and cost-effectiveness of lung screening could be further enhanced with the addition of smoking cessation interventions.

Does ethnic ancestry play a role in smoking?

The higher proportion of smokers among Black people in Brazil has been attributed to socioeconomic disparities, but genetic factors could also contribute for this finding. This study aimed at investigating associations between smoking status with genetically defined ethnic ancestry and socioeconomic features in Brazilians. Blood samples were collected from 448 volunteers (66.7% male; age: 37.1 ± 11.4 years) classified as current smokers (CS: 60.9%), former smokers (FS: 8.9%) and never smokers (NS: 30.1%). Individual interethnic admixtures were determined using a 48 insertion-deletion polymorphisms ancestry-informative-marker panel. CS showed a lower amount of European ancestry than NS (0.837 ± 0.243 X 0.883 ± 0.194, p ≤ 0.05) and FS (0.837 ± 0.243 X 0.864 ± 0.230, p ≤ 0.05), and a higher proportion of African Sub-Saharan ancestry than FS (0.128 ± 0.222 X 0.07 ± 0.174, p ≤ 0.05) and NS (0.128 ± 0.222 X 0.085 ± 0.178, p ≤ 0.05). NS reported a higher number of years in school than CS (11.2 ± 3.7 X 8.9 ± 3.8, p ≤ 0.001). CS were less common in economic Class A (30%) and more common in Class B (56.8%). In multivariate analysis, only lower number of school years and lower economic class were associated with higher chances for CS. The use of genetic molecular markers for characterizing ethnic background confirmed that socioeconomic disparities are the main determinants of higher smoking rates among Blacks in Brazil.

Differences in quit attempts between non-Hispanic Black and White daily smokers: the role of smoking motives

INTRODUCTION

The prevalence of smoking across racial/ethnic groups has declined over the years, yet racial health disparities for smoking persist. Studies indicate that non-Hispanic Black smokers attempt to quit smoking more often compared to non-Hispanic White smokers but are less successful at doing so. Research suggests that motives to quit smoking differ by race, however, less is known about the role of motives to smoke in explaining racial differences in attempts to quit smoking.

METHODS

This study examined whether smoking motives accounted for the differential rates in quit attempts between non-Hispanic Black (n=155) and non-Hispanic White (n=159) smokers. Data were culled from a larger study of heavy-drinking smokers. The Wisconsin Index of Smoking Dependence Motives (WISDM) assessed motives to smoke.

RESULTS

As expected, Black and White smokers reported similar smoking patterns, yet Black smokers reported higher rates of failed attempts to quit smoking than White smokers. Findings indicated that Black, compared to White, smokers endorsed lower scores in the negative reinforcement, positive reinforcement, and taste WISDM subscales and scores in these subscales mediated the relationship between race and quit attempts.

CONCLUSIONS

In this study, Blacks, compared to Whites, endorsed lower motives to smoke, which are generally associated with successful quit attempts, yet they experienced more failed attempts to quit smoking. This study demonstrates racial health disparities at the level of smoking motives and suggests that Black smokers remain vulnerable to failed quit attempts despite reporting lower motives to smoke.

Predictors of the Nicotine Dependence Behavior Time to the First Cigarette in a Multiracial Cohort

BACKGROUND

The time to first cigarette of the day (TTFC) is a strong indicator of nicotine dependence behaviors such as nicotine uptake and quit success in young and older smokers. There are substantial differences in levels of nicotine dependence by race and ethnic group.

METHODS

Data from Wave III of the multiracial National Longitudinal Study of Adolescent Health were analyzed for young smokers between the ages of 21 and 28 (N = 1,425). Time to first cigarette data was compared between Hispanic, White, Black, Native American, and Asian smokers.

RESULTS

Black smokers were significantly more likely to smoke within 5min of waking than White, Hispanic, and Asian smokers. Lower personal income predicted smoking within 5min of waking for both White and Black smokers. For White smokers, increased number of cigarettes per day and increased years of smoking also predicted smoking within 5min of waking. The number of days smoked or number of cigarettes per day did not predict smoking within 5min of waking among smokers.

CONCLUSIONS

The higher prevalence of early TTFC among Blacks indicates increased nicotine and carcinogen exposure, and may help explain the increased lung cancer rates and failed cessation attempts among Black smokers. TTFC may be an important screening item, independent of cigarettes per day, for clinicians and interventions to identify those at highest risk for cessation failure and disease risk.

Smoking cessation among African American and white smokers in the Veterans Affairs health care system

OBJECTIVES

We examined whether a proactive care smoking cessation intervention designed to overcome barriers to treatment would be especially effective at increasing cessation among African Americans receiving care in the Veterans Health Administration.

METHODS

We analyzed data from a randomized controlled trial, the Veterans Victory over Tobacco study, involving a population-based electronic registry of current smokers (702 African Americans, 1569 whites) and assessed 6-month prolonged smoking abstinence at 1 year via a follow-up survey of all current smokers. We also examined candidate risk adjustors for the race effect on smoking abstinence.

RESULTS

The interaction between patient race and intervention condition (proactive care vs. usual care) was not significant. Overall, African Americans had higher quit rates than Whites (13% vs. 9%; P < .006) regardless of condition.

CONCLUSIONS

African Americans quit at higher rates than Whites. These findings may be a result of the large number of veterans receiving smoking cessation services and the lack of racial differences in receipt of these services as well as racial differences in smoking history, self-efficacy, and motivation to quit that favor African Americans.

The influence of antismoking television advertisements on cessation by race/ethnicity, socioeconomic status, and mental health status

Disparities in tobacco use and smoking cessation by race/ethnicity, education, income, and mental health status remain despite recent successes in reducing tobacco use. It is unclear to what extent media campaigns promote cessation within these population groups. This study aims to (1) assess whether exposure to antitobacco advertising is associated with making a quit attempt within a number of population subgroups, and (2) determine whether advertisement type differentialy affects cessation behavior across subgroups. We used data from the New York Adult Tobacco Survey (NY-ATS), a cross-sectional, random-digit-dial telephone survey of adults aged 18 or older in New York State conducted quarterly from 2003 through 2011 (N = 53,706). The sample for this study consists of 9,408 current smokers from the total NY-ATS sample. Regression methods were used to examine the effect of New York State's antismoking advertising, overall and by advertisement type (graphic and/or emotional), on making a quit attempt in the past 12 months. Exposure to antismoking advertising was measured in two ways: gross rating points (a measure of potential exposure) and self-reported confirmed recall of advertisements. This study yields three important findings. First, antismoking advertising promotes quit attempts among racial/ethnic minority smokers and smokers of lower education and income. Second, advertising effectiveness is attributable in part to advertisements with strong graphic imagery or negative emotion. Third, smokers with poor mental health do not appear to benefit from exposure to antismoking advertising of any type. This study contributes to the evidence about how cessation media campaigns can be used most effectively to increase quit attempts within vulnerable subgroups. In particular, it suggests that a general campaign can promote cessation among a range of sociodemographic groups. More research is needed to understand what message strategies might work for those with poor mental health.

Quit interest, quit attempt and recent cigarette smoking cessation in the US working population, 2010

OBJECTIVES

To determine the prevalence of cigarette smoking cessation and examine the association between cessation and various factors among workers in a nationally representative sample of US adults.

METHODS

Data were derived from the 2010 National Health Interview Survey. Prevalence rates were calculated for interest in quitting smoking, making an attempt to quit smoking, and successful smoking cessation (defined as smokers who had quit for 6-12 months). Logistic regression analyses were used to identify factors associated with cessation after adjustment for demographic characteristics (age group, race/ethnicity, educational level and marital status).

RESULTS

Data were available for 17 524 adults who were employed in the 12 months prior to interview. The prevalence of quit interest, quit attempt and recent cessation was 65.2%, 53.8% and 6.8%, respectively. Quit interest was less likely among workers with long work hours, but more likely among workers with job insecurity, or frequent workplace skin and/or respiratory exposures. Quit attempt was more likely among workers with a hostile work environment but less likely among workers living in a home that permitted smoking or who smoked ≥11 cigarettes/day. Recent smoking cessation was less likely among workers with frequent exposure to others smoking at work or living in a home that permitted smoking, but more likely among workers with health insurance.

CONCLUSIONS

Factors associated with cessation interest or attempt differed from those associated with successful cessation. Cessation success might be improved by reducing exposure to others smoking at work and home, and by improving access to health insurance.

Clinical and individual factors associated with smoking quit attempts among adults with COPD: do factors vary with regard to race?

Only half of adults with chronic obstructive pulmonary disease (COPD) report a smoking quit attempt in the past year. Adults with COPD have frequent encounters with the healthcare system that are opportunities for health behavior interventions that support quit attempts. The purpose of this research was to examine individual- and clinical-level factors associated with smoking quit attempts in adults with COPD. Cross-sectional data were from the 2011 Behavioral Risk Factor Surveillance System. Race-stratified, weighted logistic regression examined factors associated with quit attempt among current smokers with COPD. Overall, quit attempt was reported by 65% (95% confidence interval (CI): 61.9, 67.5) of adults and was more likely among blacks than whites (p < 0.0001). Among whites with COPD quit attempt was associated with: Female gender (adjusted odds ratio (AOR) = 1.3; CI: 1.0, 1.7), exercise (AOR = 2.0; CI: 1.5, 2.5), and medications for COPD (AOR = 1.6; CI: 1.3, 2.2). Among black adults with COPD quit attempt was associated with: Having a partner (AOR = 4.5; CI: 1.3, 15.0), exercise (AOR = 3.7; CI: 1.6, 8.7), spirometry (AOR = 9.5; CI: 3.2, 28.7), and having a personal doctor (AOR = 6.4; CI: 1.8, 22.5). Individual and clinical-factors associated with quit attempt varied by race. These findings suggest an impact of the healthcare system that supports quit attempts in blacks but not whites with COPD.

Effectiveness of school-based smoking intervention in middle school students of Linzhi Tibetan and Guangzhou Han ethnicity in China

PURPOSE

The purpose of this paper is to assess the effectiveness of school-based intervention aimed to increase knowledge, to change attitudes and to reduce smoking-related behavior in both Linzhi Tibetan and Guangzhou Han middle school students in China.

DESIGN

A concurrent intervention study was conducted in both Linzhi and Guangzhou. Two schools were randomly chosen and one was randomly assigned to the intervention group and the other to the control group in both settings.

SETTING/PARTICIPANTS

Participants were grade one and grade two middle school students drawn from two schools in Linzhi, Tibet Autonomous Region (southwest China) and two schools in Guangzhou, Guangdong Province (south China).

INTERVENTION

The intervention program lasted for one year and covered three aspects: health policies in school, health environment in school and personal health skills.

MAIN OUTCOME MEASURES

Primary outcomes were smoking-related knowledge, attitudes and behavior (including ever smoking, daily smoking, weekly smoking and current smoking) and were measured by a self-administered questionnaire before and after the intervention.

RESULTS

This intervention increased smoking-related knowledge in both Tibetan (β=1.32, 95% CI (0.87-1.77)) and Han ethnic groups (β=0.47, 95% CI (0.11-0.83)). It changed attitudes toward smoking in Tibetan (β=1.47, 95% CI (0.06-2.87)) but not so in Han (β=-0.33, 95% CI (-1.68-1.01)). The intervention changed the prevalence of smoking in neither ethnic groups (P>0.05).

CONCLUSIONS

The impact of school-based smoking intervention is different among Tibetan and Han students. This intervention was more effective for Tibetans when compared with the Han ethnic group. More research is needed on how intervention can be adapted to address ethnic and cultural differences.

Racial/Ethnic differences among smokers: revisited and expanded to help seekers

INTRODUCTION

Most research on racial/ethnic differences among smokers is outdated and does not focus on help seekers. The purpose of this study was to revisit racial/ethnic differences in variables related to cessation in a sample of smokers enrolled in a randomized trial.

METHODS

Adult smokers (N = 417; n = 126 White; n = 123 Hispanic; n = 168 Black) completed measures of demographics, smoking history, alcohol use, depressive symptoms, and readiness to quit.

RESULTS

We found significant differences in these factors across groups. Blacks were more likely to be older, less educated, single, low income, smoke menthol cigarettes, and report greater nicotine dependence. Hispanics were younger, reported fewer years smoking and cigarettes per day, lower nicotine dependence, preferred mentholated cigarettes, and reported greater alcohol use intensity. After controlling for demographics and smoking history, Blacks reported greater depressive symptoms and lower readiness to quit compared with Whites and Hispanics.

CONCLUSIONS

Help-seeking Blacks may exhibit more risk factors for difficulty quitting compared with other groups. Hispanics may have some protective factors, such as lower dependence, but require attention to alcohol use and menthol smoking. Identifying preintervention racial/ethnic differences in characteristics related to cessation is important for developing evidence-based and culturally specific interventions and for reducing tobacco-related health disparities.

Associations of menthol use with motivation and confidence to quit smoking

OBJECTIVES

To examine associations of menthol cigarette use with motivation and confidence to quit smoking, and potential moderation by race, among adult current smokers (N = 1067; 85% White, 15% Black).

METHODS

Regression analyses, adjusted for sociodemographics and tobacco dependence, examined associations of menthol use with motivation and confidence to quit smoking with and without an interaction term for race.

RESULTS

Main effects were not significant; however, there was a significant interaction for confidence to quit smoking (p = .02). Stratified analyses indicated that Black menthol users were more confident about quitting than Black non-menthol users (p = .01).

CONCLUSIONS

Given their relatively lower quit rates as cited in previous literature, Black menthol users appear overly confident about their ability to quit smoking.

A history of ashes: an 80 year comparative portrait of smoking initiation in American Indians and Non-Hispanic whites--the Strong Heart Study

The consequences of starting smoking by age 18 are significant. Early smoking initiation is associated with higher tobacco dependence, increased difficulty in smoking cessation and more negative health outcomes. The purpose of this study is to examine how closely smoking initiation in a well-defined population of American Indians (AI) resembles a group of Non-Hispanic white (NHW) populations born over an 80 year period. We obtained data on age of smoking initiation among 7,073 AIs who were members of 13 tribes in Arizona, Oklahoma and North and South Dakota from the 1988 Strong Heart Study (SHS) and the 2001 Strong Heart Family Study (SHFS) and 19,747 NHW participants in the 2003 National Health Interview Survey. The participants were born as early as 1904 and as late as 1985. We classified participants according to birth cohort by decade, sex, and for AIs, according to location. We estimated the cumulative incidence of smoking initiation by age 18 in each sex and birth cohort group in both AIs and NHWs and used Cox regression to estimate hazard ratios for the association of birth cohort, sex and region with the age at smoking initiation. We found that the cumulative incidence of smoking initiation by age 18 was higher in males than females in all SHS regions and in NHWs (p < 0.001). Our results show regional variation of age of initiation significant in the SHS (p < 0.001). Our data showed that not all AIs (in this sample) showed similar trends toward increased earlier smoking. For instance, Oklahoma SHS male participants born in the 1980s initiated smoking before age 18 less often than those born before 1920 by a ratio of 0.7. The results showed significant variation in age of initiation across sex, birth cohort, and location. Our preliminary analyses suggest that AI smoking trends are not uniform across region or gender but are likely shaped by local context. If tobacco prevention and control programs depend in part on addressing the origin of AI smoking it may be helpful to increase the awareness in regional differences.

Race moderates the effect of menthol cigarette use on short-term smoking abstinence

INTRODUCTION

The Food and Drug Administration is in the process of reviewing evidence of the impact of mentholated cigarettes on smoking behaviors and smoking cessation in order to determine if these products should be removed from the market. More empirical research is needed to inform those decisions. The goal of this study was to examine associations of menthol cigarette use with biochemically verified continuous short-term smoking abstinence, and potential moderation by race, among adult current smokers enrolled in a cohort study (N = 183; 57.4% female; 48.1% non-Hispanic Black, 51.9% non-Hispanic White).

METHODS

Continuation ratio logit models, adjusted for age, race, gender, total annual household income, educational level, employment status, and partner status, were used to examine associations of menthol use with smoking abstinence with and without an interaction term for race.

RESULTS

Menthol cigarette use was not significantly associated with smoking abstinence in the sample as a whole; however, there was a significant interaction of menthol use with race (p = .03). Follow-up analyses stratified by race indicated that among White participants, menthol users had significantly lower odds of maintaining continuous abstinence than nonmenthol users (p = .05). Exploratory analyses suggested that tobacco dependence may lie along the causal pathway and partially explain this effect.

CONCLUSIONS

White menthol smokers in this sample were at increased risk of smoking relapse relative to White nonmenthol smokers, at least partially due to greater tobacco dependence. Results should be replicated among other treatment-seeking samples with a greater representation of White menthol and Black nonmenthol smokers.

Impact of Broadened Coverage of Smoking Cessation Treatments on Cardiovascular Disease

One third of all premature tobacco-attributable deaths are due to CVD and tobacco is the cause of approximately 15% of all CVD attributable. Primary and secondary prevention strategies that combine evidenced based tobacco dependence treatment programs along with cigarette taxes and media campaigns can result in hundreds of thousand of fewer excess deaths from smoking attributable CVD. Expanded insurance from both commercial and public insurers will be greatly expanded by the recently enacted federal health care reform but barriers to reducing the avoidable morbidity and mortality that is due to tobacco use is impacted by the potential for remaining financial barriers to full insurance coverage from Americans in regions of the country with the highest smoking prevalence rates.

The effect of graphic cigarette warning labels on smoking behavior: evidence from the Canadian experience

INTRODUCTION

There is a substantial literature that graphic tobacco warnings are effective; however, there is limited evidence based on actual smoking behavior. The objective of this paper is to assess the effect of graphic cigarette warning labels on smoking prevalence and quit attempts.

METHODS

A nationally representative sample of individuals aged 15 years and older from the Canadian National Population Health Survey 1998-2008 is used. The sample consists of 4,853 individuals for the smoking prevalence regression and 1,549 smokers for quit attempts. The generalized estimating equation (GEE) model was used to examine the population-averaged (marginal) effects of tobacco graphic warnings on smoking prevalence and quit attempts. To assess the effect of graphic tobacco health warnings on smoking behavior, we used a scaled variable that takes the value of 0 for the first 6 months in 2001, then increases gradually to 1 from December 2001.

RESULTS

We found that graphic warnings had a statistically significant effect on smoking prevalence and quit attempts. In particular, the warnings decreased the odds of being a smoker (odds ratio [OR] = 0.875; 95% CI = 0.821-0.932) and increased the odds of making a quit attempt (OR = 1.330, CI = 1.187-1.490). Similar results were obtained when we allowed for more time for the warnings to appear in retail outlets.

CONCLUSION

This study adds to the growing body of evidence on the effectiveness of graphic warnings. Our findings suggest that warnings had a significant effect on smoking prevalence and quit attempts in Canada.
