Ethnic comparison of attitudes and beliefs about cigarette smoking

OBJECTIVE: To determine if hypothesized differences in attitudes and beliefs about cigarette smoking between Latino and non-Latino white smokers are independent of years of formal education and number of cigarettes smoked per day. DESIGN: Cross-sectional survey using a random digit dial telephone method. SETTING: San Francisco census tracts with at least 10% Latinos in the 1990 Census. PARTICIPANTS: Three hundred twelve Latinos (198 men and 114 women) and 354 non-Latino whites (186 men and 168 women), 18 to 65 years of age, who were current cigarette smokers participated. MEASUREMENTS AND MAIN RESULTS: Self-reports of cigarette smoking behavior, antecedents to smoking, reasons to quit smoking, and reasons to continue smoking were the measures. Latino smokers were younger (36.6 vs 39.6 years, p<.01), had fewer years of education (11.0 vs 14.3 years, p<.001), and smoked on average fewer cigarettes per day (9.7 vs 20.1, p<.001). Compared with whites, Latino smokers were less likely to report smoking “almost always or often” after 13 of 17 antecedents (each p<.001), and more likely to consider it important to quit for 12 of 15 reasons (each p<.001). In multivariate analyses after adjusting for gender, age, education, income, and number of cigarettes smoked per day, Latino ethnicity was a significant predictor of being less likely to smoke while talking on the telephone (odds ratio [OR] 0.41; 95% confidence interval [CI] 0.26, 0.64), drinking alcoholic beverages (OR 0.66; 95% CI 0.44, 0.99), after eating (OR 0.55, 95% CI 0.37, 0.81), or at a bar (OR 0.62, 95% CI 0.41, 0.94), and a significant predictor of being more likely to smoke at a party (OR 1.72; 95% CI 1.14, 2.60). Latino ethnicity was a significant predictor of considering quitting important because of being criticized by family (OR 1.93; 95% CI 1.26, 2.98), burning clothes (OR 1.57; 95% CI 1.02, 2.42), damaging children’s health (OR 1.67; 95% CI 1.08, 2.57), bad breath (OR 2.07; 95% CI 1.40, 3.06), family pressure (OR 1.67; 95% CI 1.10, 2.60), and being a good example to children (OR 1.83; 95% CI 1.21, 2.76). CONCLUSIONS: Differences in attitudes and beliefs about cigarette smoking between Latinos and whites are independent of education and number of cigarettes smoked. We recommend that these ethnic differences be incorporated into smoking cessation interventions for Latino smokers.

Gender differences in the psychological determinants of cigarette smoking

Aims To compare the distributions of smoking‐related variables and the size of associations between these variables in men and women. Design and participants Mail survey in 2934 daily smokers (1533 women and 1401 men) who volunteered for a smoking cessation trial. Follow‐up after 7 months in 2456 people (84%). Setting Community setting (French‐speaking part of Switzerland, 1998). Findings Women smoked less than men (18 versus 22 cigarettes per day, p < 0.001), had lower confidence in their ability to refrain from smoking, used more frequently the strategy defined as ‘coping with the temptation to smoke’ and reported more drawbacks of smoking (gender differences ranged between 0.1 and 0.3 standard deviation units on these scales). There was no gender difference in the distribution of smokers by stage of change. At follow‐up, smoking cessation rates were similar in men and women (6% versus 5%, p = 0.3). Intention to quit, quit attempts in the previous year and a more frequent use of self‐change strategies predicted smoking cessation and were associated with tobacco dependence in both sexes. A more frequent use by women of coping strategies suggests that some women are ‘self‐restrained’ smokers who control their smoking permanently. This could explain lower smoking rates in women. The size of associations between smoking‐related variables was similar in men and women. Conclusions Even though there were gender differences in the distributions of some smoking‐related variables, associations between these variables were similar in men and women. This suggests that smoking behaviour is regulated by similar psychological mechanisms in men and women.     

Associations of CYP2A6 genotype with smoking behaviors in southern China

Aims To investigate the association of CYP2A6 genetic polymorphisms with smoking‐related phenotypes in Chinese smokers. Design Case‐only genetic association study. Setting Southern China. Participants A total of 1328 Han Chinese smokers who participated in a community‐based chronic disease screening project in Guangzhou and Zhuhai from 2006 to 2007. Measurements All participants answered a structured questionnaire about socio‐demographic status and smoking behaviors and informative alleles were genotyped for the cytochrome P450 2A6 (CYP2A6) gene (CYP2A6*4,*5,*7,*9 and *10). Findings The frequencies of CYP2A6*4, *5, *7, *9 and *10 alleles were 8.5, 1.2, 6.3, 13.5 and 2.4%, which corresponded to 48.9, 15.4, 24.2 and 11.5% of participants being classified as normal, intermediate, slow and poor metabolizers, respectively. Multivariate analyses in male smokers demonstrated that compared with normal metabolizers, poor metabolizers reported smoking fewer cigarettes per day [adjusted odds ratio (OR) = 0.49; 95% confidence interval (CI): 0.32–0.76], started smoking regularly later in life (adjusted OR = 1.55; 95% CI: 1.06–2.26) and, among former smokers, reported smoking for a shorter duration prior to quitting (adjusted OR = 0.33; 95% CI: 0.12–0.94). However, poor metabolizers were less likely to quit smoking and remain abstinent than normal metabolizers (adjusted OR = 0.54; 95% CI: 0.34–0.86). Conclusions Reduced metabolism function of cytochrome P450 2A6 in smokers appears to be associated with fewer cigarettes smoked, later initiation of smoking regularly, shorter smoking duration and lower likelihood of smoking cessation.     

Intentionally reduced smoking among untreated general population smokers: prevalence,stability, prediction of smoking behaviour change and differences between subjects choosing either reduction or abstinence

Aims To compare data from the general population on intentionally reduced smoking and smoking cessation. Design Longitudinal observation study. Setting Northern German region. Subjects Randomly sampled residents aged 18–64 (T1; n = 4075, response rate 70%). Daily cigarette smokers (n = 1520) were followed up after 30 (T2; n = 913) and 36 months (T3; n = 786). Measures Self‐reported smoking‐related and socioeconomic variables. Participants were explicitly asked for reduction attempts (reducing cigarettes per day) and maintenance of reduction, which was defined independently of consumption measures. Findings Between T1 and T2, reduction attempts (39%) were more frequent than quit attempts (33%), and according to self‐report, reduction was more likely to be maintained for up to 12 months. Smokers maintaining reduction for up to 6 months had reduced their consumption at T3 by 34% compared with T2. Between T1 and T2, the occurrence of both a reduction and a quit attempt was most frequent (22%), followed by subjects exclusively trying to reduce (17%) and subjects exclusively trying to quit (4%). Subjects who exclusively tried to reduce had a significantly increased probability of further reduction attempts at T3 (OR = 4.4, 95% CI 2.0–10.1), while the probability of quit attempts was equal compared with subjects not attempting to reduce or quit (OR = 1.1, 95% CI 0.3–3.2). DSM‐IV nicotine dependence was less common in subjects who exclusively tried to reduce. Other smoking‐related and socioeconomic variables did not predict whether individuals attempted to reduce or attempted to quit. Conclusions A considerable proportion of general population smokers attempt to reduce, and are able to maintain reduction of, cigarette consumption over time. Reduction attempts did not reduce the probability of a subsequent cessation attempt.     

Relationship between menthol cigarettes and smoking cessation among African American light smokers

AIMS: To determine whether African American light smokers who smoked menthol cigarettes had lower cessation when treated with nicotine replacement therapy and counseling. DESIGN: Data were derived from a clinical trial that assessed the efficacy of 2 mg nicotine gum (versus placebo) and counseling (motivational interviewing counseling versus Health Education) for smoking cessation among African American light smokers (smoked < or = 10 cigarettes per day). PARTICIPANTS: The sample consisted of 755 African American light smokers. MEASUREMENTS: The primary outcome variable was verified 7-day point-prevalence smoking cessation at 26 weeks follow-up. Verification was by salivary cotinine. FINDINGS: Compared to non-menthol smokers, menthol smokers were younger and less confident to quit smoking (P = 0.023). At 26 weeks post-randomization, 7-day verified abstinence rate was significantly lower for menthol smokers (11.2% versus 18.8% for non-menthol, P = 0.015). CONCLUSIONS: Among African American light smokers, use of menthol cigarettes is associated with lower smoking cessation rates. Because the majority of African American smokers use menthol cigarettes, a better understanding of the mechanism for this lower quit rate is needed.     

A smoking cessation intervention for the methadone-maintained

Aim To test, in combination with the nicotine patch, the incremental efficacy of a maximal, tailored behavioral treatment over a minimal treatment for smoking cessation. Design Randomized clinical trial with 6‐month follow‐up. Setting Five methadone maintenance treatment centers in Rhode Island. Participants Three hundred and eighty‐three methadone‐maintained smokers. Intervention Participants were assigned randomly to nicotine patch (8–12 weeks) plus either (1) a baseline tailored brief motivational intervention, a quit date behavioral skills counseling session and a relapse prevention follow‐up session (Max) or (2) brief advice using the National Cancer Institute's 4 As model (Min). An intent‐to‐treat analysis with those lost to follow‐up assumed to smoke was used. Measurements Carbon monoxide (CO)‐confirmed 7‐day point smoking cessation prevalence at 3 and 6 months, and self‐reported numbers of cigarettes smoked per day. Findings Participants had a mean age of 40 years, were 53% male, 78% Caucasian, smoked 26.7 (± 12.2) cigarettes/day and had a mean methadone dose of 95.5 mg. At 3 months, 317 (83%) were reinterviewed; at 6 months, 312 (82%) were reinterviewed. The intent‐to‐treat, 7‐day point prevalence estimate of cessation was 5.2% in the Max group and 4.7% in the Min group (P = 0.81) at 6 months. In logistic models with treatment condition, age, gender, race, Fagerström Test for Nicotine Dependence and cigarettes per day as covariates, males were more likely to be abstinent at 3 months (OR 4.67; P = 0.003) and 6 months (OR 4.01; P = 0.015). Conclusion A tailored behavioral intervention did not increase quit rates over patch and minimal treatment. Smoking cessation rates in methadone‐maintained smokers are low, with men having greater success.     

Impact of messages on concomitant use of nicotine replacement therapy and cigarettes: a randomized trial on the Internet

Aims To assess the impact of messages recommending the concomitant use of nicotine replacement therapy (NRT) and cigarettes on smokers’ intention to quit smoking. Design Randomized trial. Setting Internet. Participants A total of 2027 people who answered an e‐mail sent to 9074 current and former smokers recruited on a smoking cessation website. Intervention Participants were divided randomly into four groups, each of which received a unique message (in French) by e‐mail. The ‘control’ message said that nicotine replacement therapy (NRT) attenuates withdrawal symptoms in smokers who want to quit. The ‘temporary abstinence’ message added that NRT can also be used by current smokers to manage smoke‐free situations. The ‘reduction’ message indicated that NRT can be used by current smokers who do not want to quit but want to smoke fewer cigarettes. The ‘side‐effects’ message discouraged concomitant use of NRT and cigarettes. Measurements Perceived impact of these messages on motivation to quit smoking. Findings The e‐mail was answered by 2027 people (25% of 8124 valid addresses). Smokers who received the ‘reduction’ message were slightly more likely than controls to report that this message increased their motivation to quit (66% versus 60%, P = 0.02). In contrast, smokers who received the ‘side‐effects’ message were less likely than controls to report that this message increased their motivation (45% versus 60%, P < 0.001). The ‘temporary abstinence’ message had no detectable impact on motivation to quit. Conclusions Among smokers recruited via a smoking cessation website, messages encouraging concomitant use of NRT and cigarettes may have either no effect or a positive effect on motivation to quit smoking.     

Preliminary evidence for gender-specific effects of topiramate as a potential aid to smoking cessation

AIMS: Study aims were threefold: (i) to determine the feasibility, potential efficacy and safety of topiramate as an aid to smoking cessation; (ii) to examine potential predictors of abstinence including gender; and (iii) to explore topiramate's effects on tobacco withdrawal and post-cessation weight gain. DESIGN: Randomized, double-blind, placebo-controlled, 11-week clinical trial with a 6-week dosage titration period and 5 weeks of maintenance treatment. SETTING: Single-site, out-patient, randomized clinical trial. PARTICIPANTS: Thirty-eight adult male and 49 female chronic smokers who smoked an average of > 10 cigarettes per day and who were motivated to try to quit smoking. INTERVENTION: Random assignment to receive either topiramate (n = 43) up to 200 mg daily in divided doses or placebo (n = 44) orally combined with brief counseling over an 11-week period. MEASUREMENTS: Carbon monoxide (CO)-confirmed 4-week prolonged abstinence rate during weeks 8-11. Changes in tobacco withdrawal, body weight and safety parameters were also assessed. FINDINGS: Overall, no significant increase in the prolonged abstinence rate was detected, but logistic regression analysis indicated significant gender-specific differences. Men treated with topiramate were nearly 16 times more likely to quit smoking than women on topiramate [37.5% versus 3.7%; odds ratio (OR) = 15.6; P = 0.016] and were roughly four times more likely to quit smoking than placebo-treated men (37.5% versus 13.6%; OR = 3.8; P = 0.098). Topiramate-treated men reported significantly lower tobacco withdrawal scores than both women taking topiramate and men on placebo. On average, male cessators on placebo gained 3.30 kg, whereas topiramate led to a 0.72 kg weight loss (P = 0.03). Study discontinuation rates due to adverse events (AEs) were significantly higher in the topiramate group (topiramate 23% versus placebo 2%). The most commonly reported AEs in the topiramate arm were paraesthesia, fatigue, difficulty with concentration/attention and nervousness. CONCLUSIONS: Topiramate produced gender-specific effects on smoking cessation. Male smokers had markedly greater quit rates than female smokers and men were roughly four times more likely to quit smoking when treated with topiramate as compared to placebo. Topiramate was fairly well tolerated, although higher discontinuation rates were seen. Topiramate's triple effects aiding smoking abstinence, attenuating nicotine withdrawal and preventing post-cessation weight gain might make it a promising agent for treating tobacco addiction, at least in men.     

Associations between maternal stress and smoking: findings from a population-based prospective cohort study

Aims To investigate associations between maternal stress and smoking prior to, during and 6 months after the pregnancy. Design A prospective population‐based cohort study. Setting Norway. Participants A total of 71 757 women in the Norwegian Mother and Child Cohort Study (MoBa) participating twice during pregnancy and at 6 months postpartum. Measurements Respondents' estimates of anxiety and depression, relationship discord and negative life events were measured, along with self‐reports of smoking behaviour and demographic variables. Smoking was assessed at gestation weeks 17 and 30 and at 6 months postpartum. Findings Of the 27.5% women who smoked at conception, 55.8% quit smoking during pregnancy. At 6 months postpartum, 28.9% of quitters had relapsed to smoking. In total, 12.9% of the sample reported smoking during the pregnancy. Adjusted for well‐known risk factors, women reporting high levels of anxiety and depression had a decreased likelihood of quitting smoking during pregnancy [odds ratio (OR) 0.80, 95% confidence interval (CI): 0.73, 0.88) and an increased likelihood of relapsing after delivery (OR 1.26, 95% CI: 1.11, 1.44). Both relationship discord (OR 0.82, 95% CI: 0.75, 0.90) and exposure to negative life events (OR 0.93, 95%: CI 0.90, 0.96) had a negative influence on quitting smoking during pregnancy but had no influence on relapse to smoking postpartum. Conclusions Maternal stress and relationship discord may inhibit smoking cessation during pregnancy and promote resumption of smoking after pregnancy in women who have achieved abstinence.     

Intention to quit smoking according to smoking preferences and perceptions of electronic cigarettes among university students in South Korea

This study aimed to alleviate unhealthy smoking habits among university students and provide the basic data necessary for public health-oriented approaches such as developing regulations and policies on electronic cigarettes by analyzing the relationship between university students’ smoking preferences, perceptions of electronic cigarettes, and intention to quit smoking.This study involved 567 college students and conducted frequency and chi-squared analyses of the general characteristics, smoking preferences, and perceptions of electronic cigarettes. This study also performed logistic regression analysis to analyze the relationship between intention to quit smoking stratified by smoking preferences and the perceptions about electronic cigarettes. SPSS version 25.0 was used for data analysis.This study showed that electronic cigarette smokers were approximately 6.4 to 10.8 times more likely to think that electronic cigarettes positively affect smoking cessation attitude than nonsmokers. This study showed that regular cigarette smokers were approximately 1.7 to 2.2 times and other smoker 3.3 to 3.9 times more likely to think that electronic cigarettes positively affect smoking cessation attitude than nonsmokers. Those who perceived harmless to the human body, capable of reducing the frequency of smoking, and less harmful than tobacco were approximately 2.6 to 2.9, 11.6 to 12.8, and 3.3 to 3.7 times more likely have intention to quit smoking, respectively.Regular health education, advertising awareness of health hazards, and public health science-oriented approaches and policies for smoking cessation support services are needed to create awareness on electronic cigarettes among university students.     

Parents who quit smoking and their adult children's smoking cessation: a 20-year follow-up study

Aims   Extending our earlier findings from a longitudinal cohort study, this study examines parents' early and late smoking cessation as predictors of their young adult children's smoking cessation.
Design   Parents' early smoking cessation status was assessed when their children were aged 8 years; parents' late smoking cessation was assessed when their children were aged 17 years. Young adult children's smoking cessation, of at least 6 months duration, was assessed at age 28 years.
Setting   Forty Washington State school districts.
Participants and measurements   Participants were 991 at least weekly smokers at age 17 whose parents were ever regular smokers and who also reported their smoking status at age 28. Questionnaire data were gathered on parents and their children (49% female and 91% Caucasian) in a longitudinal cohort (84% retention).
Findings   Among children who smoked daily at age 17, parents' quitting early (i.e. by the time their children were aged 8) was associated with a 1.7 times higher odds of these children quitting by age 28 compared to those whose parents did not quit [odds ratio (OR) 1.70; 95% confidence interval (CI) 1.23, 2.36]. Results were similar among children who smoked weekly at age 17 (OR 1.91; 95% CI 1.41, 2.58). There was a similar, but non-significant, pattern of results among those whose parents quit late.
Conclusions   Supporting our earlier findings, results suggest that parents' early smoking cessation has a long-term influence on their adult children's smoking cessation. Parents who smoke should be encouraged to quit when their children are young.     

Patterns and predictors of smoking cessation in an elderly cohort

OBJECTIVES: To identify subject characteristics that predict smoking cessation and describe patterns of cessation and recidivism in a cohort of elderly smokers. DESIGN: Prospective cohort study. SETTING: Piedmont region, North Carolina. PARTICIPANTS: Five hundred seventy‐three subjects enrolled in the North Carolina Established Populations for Epidemiologic Studies of the Elderly who responded “yes” to question 179 on the baseline survey (Do you smoke cigarettes regularly now?) and survived at least 3 years, until the next in‐person follow‐up (1989/90). Subjects were classified as quitters (n=100) or nonquitters (n=473) based on subsequent smoking behavior. MEASUREMENTS: Reported smoking behavior, demographic characteristics of the smokers at baseline or subsequent interviews, 7‐year mortality. RESULTS: After controlling for all characteristics studied, subjects who quit smoking were more likely to be female (P=.03) and showed a trend toward greater likelihood of a recent cancer diagnosis (P=.11). Recidivism was observed in only 16% (19/119) of subjects who reported no smoking in 1989/90. The percentage of subjects who died during 7 years of follow‐up was 44.0% of quitters, compared with 51.6% of nonquitters. Smoking cessation was not associated with a statistically significant decrease in risk of death after controlling for other variables (odds ratio=0.78, 95% confidence interval=0.48–1.26). CONCLUSION: Smoking cessation in this elderly cohort was associated with different subject characteristics from those that predict successful cessation in younger populations, suggesting that older smokers may have unique reasons to stop smoking. Further study is needed to assess potential motives and benefits associated with smoking cessation at an advanced age.     

Changes in Smoking for Adults with and without Alcohol and Drug Use Disorders: Longitudinal Evaluation in the US Population

Background: Little is known about the smoking cessation and smoking relapse behavior of adults with alcohol use disorders (AUDs) and drug use disorders (DUDs), Objective: The current study used longitudinal data from a representative sample of the US adult population to examine changes in smoking over 3 years for men and women with and without AUD and DUD diagnoses, Methods: Participants were current or former daily cigarette smokers at Wave 1 of the National Epidemiologic Survey on Alcohol and Related Conditions who completed the Wave 2 assessment 3 years later (n = 11,973; 46% female). Analyses examined the main and gender-specific effects of AUD and DUD diagnoses on smoking cessation and smoking relapse, Results: Wave 1 current daily smokers with a current AUD (OR = .70, 95% CI = .55, .89), past AUD (OR = .73, 95% CI = .60, .89), current DUD (OR = .48, 95% CI = .31, .76), and past DUD (OR = .62, 95% CI = .49, .79) were less likely to have quit smoking at Wave 2 than those with no AUD or DUD diagnosis. Wave 1 former daily smokers with a current AUD (OR = 2.26, 95% CI = 1.36, 3.73), current DUD (OR = 7.97, 95% CI = 2.51, 25.34), and past DUD (OR = 2.69, 95% CI = 1.84, 3.95) were more likely to have relapsed to smoking at Wave 2 than those with no AUD or DUD diagnosis. The gender by diagnosis interactions were not significant, Conclusion: Current and past AUDs and DUDs were associated with a decreased likelihood of quitting smoking, while current AUDs, current DUDs, and past DUDs were associated with an increased likelihood of smoking relapse.     

Relationship of DSM-IV-based depressive disorders to smoking cessation and smoking reduction in pregnant smokers

This study investigated DSM-IV depressive disorders as predictors of smoking cessation and reduction in 81 pregnant smokers participating in a smoking cessation trial. Thirty-two percent of the sample met criteria for current dysthymia, major depressive disorder in partial remission, or minor depression. There was no significant reduction in smoking among women with or without current depressive disorders. Unexpectedly, as compared to women without depressive disorders, women with dysthymia significantly increased the mean number of cigarettes smoked (from 8 to 23 cigarettes per day during the 2 to 30 days post-targeted quit date period) and were smoking significantly more cigarettes at 30 days. A main effect approaching significance suggested that women with current depressive disorders were less likely to be abstinent than women without current depressive disorders (OR = 6.3; 3.9% vs. 12.7% at 30 days post-targeted quit date; 0% vs. 6.2% at 30 days post-partum). Results add to previous findings indicating a correlation between depressive symptoms and continued smoking in pregnant women. Further investigation of mood-focused smoking cessation interventions may be warranted.     

Role of snus (oral moist snuff ) in smoking cessation and smoking reduction in Sweden

Aims To assess to what extent snus has been used as an aid to stop smoking among Swedish smokers. Design A random telephone retrospective survey of Swedish smokers and ex‐smokers. Setting Survey conducted in November–December 2000. Participants A national sample of 1000 former and 985 current daily smokers aged 25–55 years. Measurements Smoking status, date and method of quitting by self‐report. Findings Thirty‐three per cent of former smokers and 27% of current smokers had ever used snus. The difference was larger among men (55% versus 45%, P = 0.003). Current smokers who made use of snus smoked on average fewer cigarettes per day than non‐users of snus. The mean duration of abstinence among former smokers was not influenced by snus use. Conditionally on age, education and use of nicotine replacement therapy there was an increased probability of being a former rather than a current smoker with ever use (OR 1.72, 95% CI = 1.30–2.28) or current use (OR 1.81, 95% CI = 1.31–2.53) of snus. Having used snus at the latest quit attempt increased the probability of being abstinent by about 50% (OR 1.54, 95% CI = 1.09–2.20). Conclusions Our study suggests that by using snus, Swedish male smokers may increase their overall chances of abstinence. However, 71% of the men in this sample who quit smoking did so without using snus and the duration of abstinence was not affected by snus use. This suggests that snus is not a necessary component of smoking cessation at the population level. Snus use was very rare among women.     

Impact of the 2005 smoke-free policy in Italy on prevalence, cessation and intensity of smoking in the overall population and by educational group

Aims To estimate the immediate as well as the longer‐term impact of the 2005 smoke‐free law on smoking prevalence, cessation and intensity both in the overall population and separately by educational level. Design Interrupted time–series analyses of 11 cross‐sectional nationally representative surveys. Setting Italy, 1999–2010. Participants Adults aged 20–64 years. Measurements For each year we computed the prevalence of current smoking, the quit ratio and the mean number of cigarettes smoked per day. All measures were standardized by age. Segmented linear regression analyses were performed for each smoking variable separately by sex. Findings Among males, smoking prevalence decreased by 2.6% (P = 0.002) and smoking cessation increased by 3.3% (P = 0.006) shortly after the ban, but both measures tended to return to pre‐ban values in the following years. This occurred among both highly and low‐educated males. Among low‐educated females, the ban was followed by a 1.6% decrease (P = 0.120) in smoking prevalence and a 4.5% increase in quit ratios (P < 0.001). However, these favourable trends reversed over the following years. Among highly educated females, trends in smoking prevalence and cessation were not altered by the ban. Among both males and females, long‐term trends in the daily number of cigarettes, which were already declining well before the implementation of the policy, changed to a minor extent. Conclusion The impact of the Italian smoke‐free policy on smoking and inequalities in smoking was short‐term. Smoke‐free policies may not achieve the secondary effect of reducing smoking prevalence in the long term, and they may have limited effects on inequalities in smoking.     

Change in amount smoked and readiness to quit among patients undergoing lung cancer screening

BackgroundThere is mixed evidence regarding whether undergoing computed tomography lung cancer screening (LCS) can serve as a “teachable moment” that impacts smoking behavior and attitudes. The study aim was to assess whether the standard procedures of undergoing LCS and receiving free and low-cost evidence-based cessation resources impacted short-term smoking-related outcomes.MethodsParticipants were smokers (N=87) who were registered to undergo lung screening and were enrolled in a cessation intervention trial. We conducted two phone interviews, both preceding trial randomization: the first interview was conducted prior to lung screening, and the second interview followed lung screening (median =12.5 days post-screening) and participants’ receipt of their screening results. The interviews assessed demographic characteristics, interest in evidence-based cessation intervention methods, and tobacco-related characteristics, including cigarettes per day and readiness to quit. Participants received minimal evidence-based cessation resources following the pre-lung screening interview.ResultsParticipants were 60.3 years old, 56.3% female, and reported a median of 40 pack-years. Participants were interested in using several evidence-based strategies, including counseling from a healthcare provider (76.7%) and receiving nicotine replacement therapy (69.8%). Pre-lung screening, 25.3% smoked ≤10 cigarettes per day, and 29.9% were ready to quit in the next 30 days. We conducted two McNemar binomial distribution tests to assess change from pre- to post-screening. At the post-lung screening assessment, approximately three-quarters reported no change on these variables. However, 23.3% reported smoking fewer cigarettes per day, whereas 4.7% reported smoking more cigarettes per day (McNemar P=0.002), and 17.2% reported increased readiness to quit, whereas 6.9% reported decreased readiness to quit (McNemar P=0.078).ConclusionsFollowing receipt of cessation resources and completion of lung screening, most participants reported no change in smoking outcomes. However, there was a significant reduction in cigarettes per day, and there was a trend for increased readiness to quit. This setting may provide a potential “teachable moment” and an opportunity to assist smokers with quitting. However, more proactive and intensive interventions will be necessary to capitalize on these changes and to support abstinence in the long-term.     

A Pilot Trial Examining African American and White Responses to Algorithm-Guided Smoking Cessation Medication Selection in Persons Living with HIV

Algorithm-based treatments (AT) may be an effective clinical tool to aid HIV clinicians in prescribing pharmacotherapy to increase smoking cessation among people living with HIV (PLWH). Initial results from AT indicated significant increases in abstinence self-efficacy and medication utilization and declines in cigarettes smoked per day across time. Given historical racial disparities, it is unclear if both African Americans and White smokers would benefit equally from this type of intervention. Thus, the aim of this study was to examine racial differences in response to AT guided smoking cessation for African American and White smokers living with HIV. One hundred PLWH smokers (n = 100) were randomized to receive either AT guided smoking cessation or Treatment as Usual (TAU) which consisted of instructing participants to talk to a provider about smoking cessation assistance when ready to make a quit attempt. Participants were African American (75%) and White (25%) and majority men (71%) who had never been married (56%). African Americans smoked fewer cigarettes and were more likely to smoke mentholated cigarettes compared to White smokers at baseline. African Americans increased their use of other tobacco products (cigars/cigarillos) over time relative to White smokers. A significant interaction between race and quit goal was observed, with White smokers who reported complete abstinence as their goal having higher quit rates, while African Americans who reported a goal other than complete abstinence demonstrating higher quit rates. The increased use of cigars/cigarillos during quit attempts as well as having a goal other than complete abstinence should be considered when applying algorithm based interventions for PLWH African American smokers.     

Effectiveness of a smoking cessation intervention in older adults

AIMS: To: (a) identify characteristics of older smokers considering cessation of smoking; (b) evaluate a cessation intervention plus access to nicotine replacement therapy (NRT); (c) identify predictors of those who successfully quit; and (d) evaluate the effectiveness of the intervention in those AGED >or = 75 years. DESIGN: Self-selection of: (a) a cessation of smoking programme; or (b) ongoing smoking. SETTING: Teaching hospital, Perth, Western Australia. PARTICIPANTS: A larger study recruited smokers and never smokers: from this the 215 community-dwelling smokers (>or= 5 cigarettes/day) aged >or= 68 years (171 males) were enrolled. INTERVENTION: Brief intervention with telephone support and access to NRT versus no intervention. MEASUREMENTS: (a) Profile of older adults planning to quit smoking compared with continuing smokers; (b) cessation at 6 months defined as 30-day point prevalence validated via expired carbon monoxide; and (c) factors predictive of successful cessation. FINDINGS: There were 165 intervention participants. Compared with the 50 continuing smokers, participants in the intervention were younger and had significantly less years of regular smoking, more previous quit attempts and greater nicotine dependence scores. At 6 months, the point prevalence of ex-smokers was 25% (n = 42) with 20% (n = 33) being abstinent throughout the study. No continuing smoker had ceased smoking. Among the intervention group, logistic regression showed that those who used NRT (OR 4.36), were male (OR 3.17), had higher anxiety (OR 1.67) or rejected 'more colds and coughs' as a reason for quitting (OR 2.91) were more likely to be successful quitters. Of those aged >or= 75 years (n = 77), 25% matched cessation criteria. CONCLUSIONS: Older smokers can be engaged successfully in a brief intervention plus NRT as aids to cessation of smoking. The intervention was also effective in the older subgroup of participants. Social factors may provide an additional means of motivating older smokers to quit.
