RESUMEN

BACKGROUND: Prevalence of smoking is high among patients receiving care in safety-net settings, and there is a need to better understand patient factors associated with smoking cessation and receipt of cessation services. OBJECTIVE: To identify patient factors associated with smoking cessation attempts and receipt of cessation counseling and pharmacotherapy in a large safety-net health system. DESIGN: We conducted a retrospective cohort analysis using EHR data in a safety-net system in San Francisco, CA. PARTICIPANTS: We included 7384 adult current smokers who had at least three unique primary care encounters with documented smoking status between August 2019 and April 2022. MAIN MEASURES: We assessed four outcomes using multivariate generalized estimating equation models: (1) any cessation attempt, indicating a transition in smoking status from "current smoker" to "former smoker"; (2) sustained cessation, defined as transition in smoking status from current smoker to former smokers for two or more consecutive visits; (3) receipt of smoking cessation counseling from healthcare providers; and (4) receipt of pharmacotherapy. KEY RESULTS: Of 7384 current adult smokers, 17.6% had made any cessation attempt, and of those 66.5% had sustained cessation. Most patients (81.1%) received counseling and 41.8% received pharmacotherapy. Factors associated with lower odds of any cessation attempt included being aged 45-64, non-Hispanic black, and experiencing homelessness. The factor associated with lower odds of sustained cessation was being male. Factors associated with lower odds of receiving counseling were being insured by Medicaid or being uninsured. Factors associated with lower odds of receiving pharmacotherapy included speaking languages other than English, being male, and identifying as racial and ethnic minorities. CONCLUSIONS: Health system interventions could close the gap in access to smoking cessation services for unhoused and racial/ethnic minority patients in safety-net settings, thereby increasing cessation among these populations.

RESUMEN

BACKGROUND: Smoking is a known risk factor for psoriasis; however, the impact of smoking cessation on psoriasis has seldom been evaluated. OBJECTIVES: We aimed to examine the effects of smoking cessation on the development of psoriasis vulgaris (PsV), palmoplantar pustulosis (PPP) and generalized pustular psoriasis (GPP). METHODS: Using the Korean National Health Insurance Service database, we retrospectively compiled a cohort of 5 784 973 participants without psoriasis, analysed their changes in smoking status from 2004 to 2007 and followed up new cases of psoriasis until 2021. The psoriasis risks were compared with those of sustained smokers, smoking quitters, sustained ex-smokers and never smokers using multivariate Cox proportional hazard models. RESULTS: The mean age of the participants was 47.1 years (SD 13.5) and 3 092 426 (53.5%) were male. During 77 990 688 person-years, 67 364 psoriasis cases were identified. Compared with sustained smokers, smoking quitters showed a reduced risk of developing psoriasis [adjusted hazard ratio (aHR) 0.91; 95% confidence interval (CI) 0.87-0.95], specifically PsV (aHR 0.92; 95% CI 0.88-0.97) and PPP (aHR 0.71; 95% CI 0.63-0.79). The reduction in risk due to smoking cessation was more prominent in sustained ex-smokers (psoriasis: aHR 0.77, 95% CI 0.74-0.79; PsV: aHR 0.76, 95% CI 0.73-0.79; PPP: aHR 0.56, 95% CI 0.51-0.61; GPP: aHR 0.64; 95% CI 0.52-0.78). When conducting sensitivity analyses to address the potential for changes in smoking habits after 2007, the results and trends were consistent with the main findings, and a more pronounced significance was observed. CONCLUSIONS: Compared with continuous smoking, smoking cessation was associated with a decreased risk of developing psoriasis. The risk-reducing effect of smoking cessation was more pronounced in those maintaining a smoke-free status. Smoking cessation and the maintenance of a smoke-free status should be encouraged to prevent the development of psoriasis and all other smoking-related diseases.


Psoriasis vulgaris (PsV) is a chronic inflammatory skin condition that causes scaly plaques on the body. Pustular psoriasis [including palmoplantar pustulosis (PPP) and generalized pustular psoriasis (GPP)] is a variant characterized by sterile pustules. Limited evidence exists on how quitting smoking affects psoriasis and its subtypes. In this study conducted in South Korea, we aimed to investigate how changes in smoking habits, especially quitting smoking, could impact the development of psoriasis. We used medical claims records from the Korean National Health Insurance Service database, which included data from over 5.7 million people participating in health checkups between 2004 and 2007. We divided people into four groups based on their smoking habits: sustained smokers, smoking quitters, sustained ex-smokers and never smokers. We found that smoking quitters had a lower risk of developing psoriasis, especially PsV and PPP. Even people who had quit smoking and remained smoke-free for an extended period (sustained ex-smokers) showed a more pronounced reduction in the risk of psoriasis, including PsV, PPP and GPP. Our findings remained consistent across various groups of people, considering factors such as age, sex, weight and overall health. The results suggest that encouraging people to quit smoking and maintain a smoke-free lifestyle may help to prevent the onset of psoriasis. In conclusion, this large-scale study from South Korea provides real-world evidence to suggest that quitting smoking could reduce the risk of developing psoriasis. These findings are valuable for public health initiatives, emphasizing the benefits of quitting smoking for skin health.

RESUMEN

Tobacco dependence is a chronic condition driven by nicotine addiction. Successful quitting can be increased by health care provider intervention and evidence-based treatment. CDC assessed national estimates of cigarette smoking cessation indicators among U.S. adults using 2022 National Health Interview Survey data. In 2022, approximately two thirds (67.7%) of the 28.8 million U.S. adults who smoked wanted to quit, and approximately one half (53.3%) made a quit attempt, but only 8.8% quit smoking. One half of adults who smoked and saw a health professional during the past year received health professional advice (50.5%) or assistance (49.2%) to quit smoking. Among those who tried to quit, 38.3% used treatment (i.e., counseling or medication). Adults who usually smoked menthol (versus nonmenthol) cigarettes had higher prevalences of quitting interest (72.2% versus 65.4%; p<0.05) and past-year quit attempts (57.3% versus 50.4%; p<0.05), lower prevalences of receiving quit advice (48.2% versus 53.8%; p<0.05) and using cessation treatment (35.2% versus 41.5%; p<0.05), but similar prevalence of quit success (9.5% versus 7.9%; p = 0.19). Opportunities exist for both public health and health care sectors to increase smoking cessation, including expanding access to and utilization of cessation services and supports. Incorporating equitable cessation strategies into all commercial tobacco prevention and control efforts can help advance and support smoking cessation for all population groups.

RESUMEN

Cigarette smoking during pregnancy increases the risk for pregnancy complications and adverse infant outcomes such as preterm delivery, restricted fetal growth, and infant death. Health care provider counseling can support smoking cessation. Data from the 2021 Pregnancy Risk Assessment Monitoring System were analyzed to estimate the prevalence of smoking before, during, and after pregnancy; quitting smoking during pregnancy; and whether health care providers asked about cigarette smoking before, during, and after pregnancy among women with a recent live birth. In 2021, the prevalence of cigarette smoking was 12.1% before pregnancy, 5.4% during pregnancy, and 7.2% during the postpartum period; 56.1% of women who smoked before pregnancy quit smoking while pregnant. Jurisdiction-specific prevalences of smoking ranged from 3.5% to 20.2% before pregnancy, 0.4% to 11.0% during pregnancy, and 1.0% to 15.1% during the postpartum period. Among women with a health care visit during the associated period, the percentage of women who reported that a health care provider asked about smoking was 73.7% at any health care visit before pregnancy, 93.7% at any prenatal care visit, and 57.3% at a postpartum checkup. Routine assessment of smoking behaviors among pregnant and postpartum women can guide the development and implementation of evidence-based tobacco control measures at the jurisdiction and health care-system level to reduce smoking among pregnant and postpartum women.

RESUMEN

Randomized trials seek efficient treatment effect estimation within target populations, yet scientific interest often also centers on subpopulations. Although there are typically too few subjects within each subpopulation to efficiently estimate these subpopulation treatment effects, one can gain precision by borrowing strength across subpopulations, as is the case in a basket trial. While dynamic borrowing has been proposed as an efficient approach to estimating subpopulation treatment effects on primary endpoints, additional efficiency could be gained by leveraging the information found in secondary endpoints. We propose a multisource exchangeability model (MEM) that incorporates secondary endpoints to more efficiently assess subpopulation exchangeability. Across simulation studies, our proposed model almost uniformly reduces the mean squared error when compared to the standard MEM that only considers data from the primary endpoint by gaining efficiency when subpopulations respond similarly to the treatment and reducing the magnitude of bias when the subpopulations are heterogeneous. We illustrate our model's feasibility using data from a recently completed trial of very low nicotine content cigarettes to estimate the effect on abstinence from smoking within three priority subpopulations. Our proposed model led to increases in the effective sample size two to four times greater than under the standard MEM.

RESUMEN

INTRODUCTION: The influence of pack-year history and smoking cessation timing on postoperative morbidity and mortality in a highly comorbid cohort is uncertain. We examined whether the association between smoking and adverse postoperative events is modified by pack-year history and smoking cessation timing. METHODS: We collected single-institution, retrospective data from consecutive patients undergoing open operations for carotid, aortic, and infrainguinal arterial disease. Active smoking was defined as smoking on the day of the index surgical intervention. Duration of smoking cessation was calculated as the time between smoking cessation and index surgery. The primary outcome was a composite of 30-day mortality and morbidity. Logistic and time-to-event Cox regressions estimated associations with interactions between cessation duration and pack-year history for nonactive smokers. RESULTS: Between 2010 and 2019, 1087 patients underwent 1640 high-risk vascular interventions. Median pack-year history was 40.0 pack-years (interquartile range [IQR]: 20.0-60.0) among nonactive smokers and 46.0 pack-years (IQR: 31.0-61.0) among active smokers (P < 0.001). The median smoking cessation time was 15.5 y (IQR: 4.4-30.9). Smoking status did not independently predict an increased risk of postoperative mortality or morbidity (odds ratio [OR] = 0.99, P = 0.96). Among nonactive smokers, neither smoking cessation duration (OR = 0.99, P = 0.16) nor pack-year history (OR = 1.00, P = 0.88) were significantly associated with adverse events (interaction P = 0.11). CONCLUSIONS: After high-risk vascular interventions in a single institution, active smoking, cessation period, and pack-year history are not associated with an increased risk of postoperative morbidity or mortality-highlighting the benefit of cessation as independent of frequency or intensity.

RESUMEN

OBJECTIVE: Both diabetes and smoking significantly increase the risk of cardiovascular disease (CVD). Understanding whether a diagnosis of diabetes can be leveraged to promote smoking cessation is a gap in the literature. METHODS: We used data from the US National Health Interview Survey, 2006 to 2018, to investigate the relationship between self-report of diagnosis of diabetes and subsequent smoking abstinence among 142,884 respondents who reported regular smoking at baseline. Effect sizes were presented as hazard ratios (HRs) derived from multivariable Cox regression models adjusted for potential confounders using diabetes as a time-dependent covariate. Subgroup-specific estimates were obtained using interaction terms between diabetes and variables of interest. RESULTS: A self-reported diagnosis of diabetes was associated with smoking abstinence (HR: 1.21; 95% CI: 1.16 to 1.27). The strength of the association varied based on race (P for interaction: 0.004), where it was strongest in African Americans (HR: 1.44; 95% CI: 1.29 to 1.60); income (P for interaction <0.001), where it was strongest in those with a yearly income less than $35,000 (HR: 1.45; 95% CI: 1.36 to 1.53); and educational attainment (P for interaction <0.001), where it was strongest in those who did not attend college (HR: 1.48; 95% CI: 1.40 to 1.57). CONCLUSION: Among adults who smoke, a diagnosis of diabetes is significantly associated with subsequent smoking abstinence. The association is strongest in socially disadvantaged demographics, including African Americans, low-income individuals, and those who did not attend college.

RESUMEN

SIGNIFICANCE: A growing number of adults use more than one tobacco product, with dual use of cigarettes and e-cigarettes being the most common combination. Monitoring sex disparities in tobacco use is a public health priority. However, little is known regarding whether dual users differ by sex. METHODS: Data came from Waves 4-6 (12/2016-11/2021) of the Population Assessment of Tobacco and Health Study, a US nationally-representative longitudinal survey. This analysis included current adult dual users of cigarettes and e-cigarettes. We used weighted generalized estimating equations to assess the association between sex and (1) making a cigarette quit attempt (n = 1882 observations from n = 1526 individuals) and (2) smoking cessation (n = 2081 observations from n = 1688 individuals) across two wave pairs, adjusting for age, education, ethnicity, time-to-first cigarette after waking, and e-cigarette use frequency. RESULTS: Among US dual users, 14.1% (95% Confidence Intervals [Cl] = 11.9-16.4) of females and 23.4% (20.0-26.9) of males were young adults (aged 18-24), 11.7% (9.2-14.2) of females and 14.4% (11.6-17.2) of males had

RESUMEN

OBJECTIVE: This study is part of a programmatic investigation of rural disparities in cigarette smoking examining disparities in smoking prevalence and for the first-time quit ratios among adult women of reproductive age (18-44 years), a highly vulnerable population due to risk for multigenerational adverse effects. METHODS: Data came from 18 years (2002-2019) of the U.S. National Survey on Drug Use and Health (NSDUH) among women (n = 280,626) categorized by rural-urban residence, pregnancy status, using weighted logistic regression models testing time trends and controlling for well-established sociodemographic predictors of smoking (race/ethnicity, education, income). Concerns regarding changes in survey methods used before 2002 and after 2019 precluded inclusion of earlier and more recent survey years in the present study. RESULTS: Overall smoking prevalence across years was greater in rural than urban residents (adjusted odds ratio [AOR] = 1.11; 95%CI, 1.07-1.15; P < .001) including those not-pregnant (AOR = 1.10; 1.07-1.14; P < .001) and pregnant (AOR = 1.29; 1.09-1.52; P < .001). Overall quit ratios across years were lower in rural than urban residents (AOR = 0.93; 0.87-0.99; P < .001) including those not-pregnant (AOR = 0.93; 0.88-1.00, P = .035) and pregnant (AOR = 0.78; 0.62-0.99; P = .039). Interactions of rural versus urban residence with study years for prevalence and quit ratios overall and by pregnancy status are detailed in the main text. CONCLUSIONS: These results support a longstanding and robust rural disparity in smoking prevalence among women of reproductive age including those currently pregnant and provides novel evidence that differences in smoking cessation contribute to this disparity further underscoring a need for greater access to evidence-based tobacco control and regulatory interventions in rural regions.

RESUMEN

We propose a compartmental model for investigating smoking dynamics in an Italian region (Tuscany). Calibrating the model on local data from 1993 to 2019, we estimate the probabilities of starting and quitting smoking and the probability of smoking relapse. Then, we forecast the evolution of smoking prevalence until 2043 and assess the impact on mortality in terms of attributable deaths. We introduce elements of novelty with respect to previous studies in this field, including a formal definition of the equations governing the model dynamics and a flexible modelling of smoking probabilities based on cubic regression splines. We estimate model parameters by defining a two-step procedure and quantify the sampling variability via a parametric bootstrap. We propose the implementation of cross-validation on a rolling basis and variance-based Global Sensitivity Analysis to check the robustness of the results and support our findings. Our results suggest a decrease in smoking prevalence among males and stability among females, over the next two decades. We estimate that, in 2023, 18% of deaths among males and 8% among females are due to smoking. We test the use of the model in assessing the impact on smoking prevalence and mortality of different tobacco control policies, including the tobacco-free generation ban recently introduced in New Zealand.

RESUMEN

BACKGROUND: Although many studies suggested the benefit of smoking cessation among pregnant women in reducing the risk of preterm birth (PTB), the timing of the effect of the cessation remains inconclusive. OBJECTIVES: To examine the association of trimester-specific smoking cessation behaviours with PTB risk. METHODS: We included 199,453 live births in Western New York between 2004 and 2018. Based on self-reported cigarette smoking during preconception and in each trimester, we created six mutually exclusive groups: non-smokers, quitters in each trimester, those who smoked throughout pregnancy, and inconsistent smokers. Risk ratios (RRs) and 95% confidence intervals (CIs) were estimated using Poisson regression to examine the association between smoking cessation and PTB. Effect modification by illegal drug use, maternal age, race and ethnicity and pre-pregnancy body mass index (BMI) was investigated multiplicatively by ratio of relative risk and additively by relative excess risk due to interaction (RERI). RESULTS: Overall, 6.7% of women had a PTB; 14.1% smoked throughout pregnancy and 3.4%, 1.8% and 0.8% reported quitting smoking during the first, second and third trimesters, respectively. Compared to non-smokers, third-trimester cessation (RR 1.20, 95% CI 1.01, 1.43) and smoking throughout pregnancy (RR 1.27, 95% CI 1.21, 1.33) were associated with a higher PTB risk, while quitting smoking during the first or second trimester, or inconsistent smoking was not associated with PTB. A positive additive interaction was identified for maternal age and late smoking cessation or smoking throughout pregnancy on PTB risk (RERI 0.17, 95% CI 0.00, 0.36), and a negative interaction was observed for pre-pregnancy BMI ≥30 kg/m2 (ratio of relative risk 0.70, 95% CI 0.63, 0.78; RERI -0.42, 95% CI -0.56, -0.30). CONCLUSION: Compared to non-smokers, smoking throughout pregnancy and third-trimester smoking cessation are associated with an increased risk of PTB, while quitting before the third trimester may not increase PTB risk.

RESUMEN

With highly active antiretroviral therapy, HIV infection has become a treatable chronic disease. However, modifiable risk factors such as cigarette smoking continue to impact the morbidity and mortality of people with HIV (PWH). We assessed the prevalence and factors associated with cigarette smoking and motivation to quit among PWH in Western Jamaica. A cross-sectional study was conducted in which 392 adults seeking HIV care at health facilities in Western Jamaica completed an interviewer-administered questionnaire. Current smoking prevalence among participants was 17.4%. Current smoking was significantly associated with being male (OR = 2.99), non-Christian/non-Rastafarian (OR = 2.34), living or working with another smoker (aOR =1.86), being moderate to severely depressed (OR = 3.24), having an alcohol drinking problem (OR = 1.84), and never being asked by a healthcare provider if they smoked (OR = 3.24). Among the PWH who currently smoke, 36.7% are moderately to highly dependent on nicotine. One-third of people who smoke (33.8%) started smoking for the first time after HIV diagnosis, while 66.2% initiated smoking before; 88% were willing to quit smoking. These findings provide baseline information for designing and implementing a comprehensive smoking cessation program that considers the needs of PWH in Jamaica, with the potential of becoming a replicable model for other HIV-specialized healthcare settings in the Caribbean.

RESUMEN

INTRODUCTION: Our safety-net hospital implemented a hospital-based tobacco treatment intervention in 2016. We previously showed the intervention, an "opt-out" Electronic Health Record (EHR)-based Best Practice Alert (BPA)+ order-set that triggers consultation to an inpatient Tobacco Treatment Consult (TTC) service for all patients who smoke, improves smoking abstinence. We now report on sustainability, 6 years after inception. AIMS AND METHODS: We analyzed data collected between July 2016-June 2022 of patients documented as "currently smoking" in the EHR. Across the 6 years, we used Pearson's correlation analysis to compare Adoption (clinician acceptance of the BPA+ order-set, thus generating consultation to the TTC service); Reach (number of consultations completed by the TTC service); and Effectiveness (receipt of pharmacotherapy orders between patients receiving and not receiving consultations). RESULTS: Among 39 558 adult admissions (July 2016-June 2022) with "currently smoking" status in the EHR for whom the BPA triggered, clinicians accepted the TTC order set on 50.4% (19 932/39 558), though acceptance varied across services (eg, Cardiology [71%] and Obstetrics-Gynecology 12%]). The TTC service consulted on 17% (6779/39 558) of patients due to staffing constraints. Consultations ordered (r = -0.28, p = .59) and completed (r = 0.45, p = .37) remained stable over 6-years. Compared to patients not receiving consultations, patients receiving consultations were more likely to receive pharmacotherapy orders overall (inpatient: 50.8% vs. 35.1%, p < .0001; at discharge: 27.1% vs. 10%, p < .0001) and in each year. CONCLUSIONS: The "opt-out" EHR-based TTC service is sustainable, though many did not receive consultations due to resource constraints. Health care systems should elevate the priority of hospital-based tobacco treatment programs to increase reach to underserved populations. IMPLICATIONS: Our study shows that opt-out approaches that utilize the EHR are a sustainable approach to providing evidence-based tobacco treatment to all hospitalized individuals who smoke, regardless of readiness to stop smoking and clinical condition.

RESUMEN

INTRODUCTION: Recruiting special populations to smoking cessation trials is challenging and approaches beyond in-clinic recruitment may be beneficial. This secondary analysis of data from a smoking cessation RCT for individuals with a history of cervical cancer or cervical intraepithelial neoplasia (CIN) explored differences associated with in-clinic vs. online recruitment. AIMS AND METHODS: Participants were recruited from clinics within a university-based NCI-designated cancer center (n = 87) and online nationally via Facebook (n = 115). Baseline measures included sociodemographics, smoking history, and cancer or CIN history. Study retention and smoking abstinence were assessed 12 months post-baseline. Group differences in baseline characteristics were evaluated. Retention and abstinence were evaluated while controlling for group differences and predictors. RESULTS: Participants recruited online (vs. in-clinic) had higher educational attainment (p = .01) and health literacy (p = .003). They were more likely to have CIN versus cancer, to be further from the time of diagnosis, and to have completed active treatment (p values < .001). While controlling for these group differences and independent predictors, retention was higher among participants recruited online (log-likelihood χ2(1) = 11.41, p < .001). There were no recruitment differences in self-reported (p = .90) or biochemically confirmed smoking abstinence (p = .18). CONCLUSIONS: Compared to individuals recruited in-person, individuals recruited online were more educated, had higher health literacy, and presented with a different clinical profile (ie, more likely to have CIN vs. cancer and to have completed active treatment). There were few differences in participant characteristics between recruitment approaches, and no differences on any smoking-related variables. Online recruitment has the potential to improve enrollment of cancer survivors in smoking cessation trials. IMPLICATIONS: People with a history of CIN or cervical cancer recruited to a smoking cessation RCT online (vs. in-clinic) were more likely to have a diagnosis of CIN versus cancer and were more educated and health literate. Participants recruited online were more likely to be retained in the study and there were no differences in smoking abstinence rates at 12 months. Incorporating online recruitment increased the reach of tobacco treatment efforts to a larger and more diverse sample. This could reduce the burden of tobacco-related disease, improve CIN and cancer treatment outcomes, and reduce secondary malignancies and morbidity among this underserved group.

RESUMEN

BACKGROUND: Flavorings in cigars increase their appeal, mask the harsh taste of tobacco, and may hinder successful cigar smoking cessation; however, limited evidence has examined whether flavors are associated with short- or long-term cigar smoking cessation. AIMS AND METHODS: Using restricted data from the Population Assessment of Tobacco and Health Study Waves 1-5, we examined whether flavored cigar use was associated with 30-day-plus and 1-year-plus cigar smoking cessation among US adults. Multivariable discrete-time survival models were fit to a nationally representative sample of US adult (18+) respondents who had a current, established cigar use, smoked five or more days in the past 30 days, and did not exclusively smoke traditional premium cigars at baseline. Models adjusted for age, sex, race and ethnicity, income, cigar and cigarette smoking intensity, and blunt use. RESULTS: At baseline, 44.6% of respondents (n = 674) were 18-34 years old, 75.0% were male, 56.7% were non-Hispanic White, 78.9% had household incomes of <$50,000, and 56.2% smoked flavored cigars. In fully adjusted models, flavored cigar use was associated with a lower risk of 30-day-plus (HR = 0.76, 95% CI = 0.60, 0.97) but not 1-year-plus cigar smoking cessation (HR = 0.81, 95% = 0.62, 1.05). CONCLUSIONS: We found that flavored cigar use was associated with a lower risk of short-term but not long-term cigar smoking cessation. More work is needed to understand the dynamics of cigar smoking transitions, including initiation, cessation, and relapse, particularly in larger cohorts and among those who exclusively use cigars or dual-use cigars and cigarettes. IMPLICATIONS: As local and some state jurisdictions continue to adopt partial or complete bans of flavored cigar products and the United States Food and Drug Administration considers a national ban of all characterizing flavors in cigars, there is a need for more longitudinal work examining the associations between flavorings in cigars and short and long-term cigar-smoking behaviors, including but not limited to initiation, cessation, intensity of use, and relapse, particularly in diverse cohorts.

RESUMEN

INTRODUCTION: Trial evidence suggests that e-cigarettes may aid in quitting smoking, while observational studies have found conflicting results. However, many observational studies have not adjusted for important differences between e-cigarette users and non-users. AIMS AND METHODS: We aimed to determine the association between e-cigarette use frequency and motivation to use e-cigarettes to quit smoking, and smoking cessation using data from Canada's largest smoking cessation program. Participants who completed a baseline assessment and 6-month follow-up questionnaire were divided post hoc into four groups based on their self-reported e-cigarette use during the 30 days before baseline: (1) non-users; (2) users of e-cigarettes not containing nicotine; (3) occasional users; and (4) frequent users. Occasional and frequent users were further divided into two groups based on whether they reported using e-cigarettes to quit smoking. Abstinence at 6-month follow-up (7-day point prevalence abstinence) was compared among groups. RESULTS: Adjusted quit probabilities were significantly higher (both p < .001) for frequent baseline e-cigarette users (31.6%; 95% CI = 29.3%, 33.8%) than for non-users (25.8%; 25.3% and 26.3%) or occasional users (24.2%; 22.5% and 26.0%). Unadjusted proportions favored non-users over occasional users (p < .001), but this was not significant after adjustment (p = .06). People using e-cigarettes to quit smoking were not likelier than other users to be successful, but were likelier to report frequent e-cigarette use during follow-up. CONCLUSIONS: Frequent baseline e-cigarette use predicted successful smoking cessation, compared to occasional and non-users. Use of e-cigarettes to quit did not predict smoking cessation but was associated with continued use during follow-up, perhaps due in part to planned transitions to e-cigarettes. IMPLICATIONS: Prior observational studies investigating e-cigarette use for smoking cessation have found that occasional users have poorer outcomes than either frequent or non-users. Consistent with these studies, occasional users in our data also had poorer outcomes. However, after adjustment for variables associated with cessation success, we found that cessation probabilities did not differ between occasional and non-users. These findings are consistent with trial data showing the benefit of e-cigarette use among people trying to quit smoking. Results of this study suggest that differences between trials and previous observational studies may be because of unaddressed confounding in the latter.

RESUMEN

INTRODUCTION: Achieving cessation in people with established smoking patterns remains a challenge. Increasing cigarette prices has been one of the most successful strategies for lowering smoking rates. The extent to which it has remained effective in encouraging cessation among adults in recent years and how the effectiveness has varied by sociodemographic characteristics is unclear. AIMS AND METHODS: Using repeated cross-sectional data collected by the Tobacco Use Supplement of the Current Population Survey, we investigate the relationship between cigarette prices and cessation from 2003 to 2019 in adults at least 25 years old. We examine the associations between price and cessation in the population overall and by sex, race and ethnicity, and socioeconomic status. RESULTS: We found mixed support for associations between greater local prices and cessation. Unadjusted models showed that greater local prices were associated with greater odds of cessation, but the associations did not persist after controlling for sociodemographic characteristics. The associations did not significantly differ by respondent characteristics. Sensitivity analysis using alternative specifications and retail state price as the main predictor showed similar results. Sensitivity analysis with controls for e-cigarette use in the 2014-2019 period showed that greater local price was associated with cessation among adults with less than a high school degree. When stratified by year of data collection, results show that greater local prices were associated with cessation after 2009. CONCLUSIONS: Overall, the study adds to the conflicting evidence on the effectiveness of increasing prices on smoking cessation among adults with established smoking patterns. IMPLICATIONS: Higher cigarette prices have been one of the most successful tools for lowering smoking prevalence. It remains unclear how effective they have been in recent years in encouraging adults with established smoking patterns to quit. The study's results show that greater local prices were associated with higher odds of cessation, but the association did not persist after sociodemographic adjustment. In a sensitivity analysis, greater local price was associated with cessation among people with less than a high school degree in models controlling for e-cigarette use. We also found evidence that greater local price was associated with cessation after 2009. More comprehensive smoke-free coverage was also associated with greater odds of cessation. The study's results highlight that encouraging cessation among adults with an established smoking pattern remains a challenging policy problem even when cigarette prices rise.

RESUMEN

INTRODUCTION: Health agencies have called for research evaluating e-cigarette (EC) use in supporting prenatal smoking cessation. This study aimed to describe (1) the characteristics of smokers who begin using electronic cigarettes (ECs) during pregnancy, (2) how frequently smokers reduce or eliminate pre- and post-natal combustible cigarette (CC) use, and (3) the risk for neonatal health complications among smokers who initiate ECs during pregnancy. AIMS AND METHODS: Pregnant women using CCs exclusively during prepregnancy, who participated in a U.S. surveillance study, were classified by their reported late-pregnancy smoking behavior as CC-exclusive users, EC initiators, or quitters. EC initiators were further subclassified as dual users (used both ECs and CCs) or EC replacers (used ECs exclusively). RESULTS: Of 29 505 pregnant smokers, 1.5% reported using ECs during the last three pregnancy months. Among them, 29.7% became EC-exclusive users. EC initiators were disproportionately non-Hispanic White. Relative to quitters, EC initiators had lower income, were less likely to be married, have intended pregnancies, receive first-trimester prenatal care, and participate in a federal assistance program. Compared to CC-exclusive users, EC initiators overall, and dual users specifically, were more likely to reduce pre- and post-natal CC usage relative to prepregnancy levels. EC initiators' risk for neonatal health complications fell between quitters and CC-exclusive users, though the differences were not statistically significant. CONCLUSIONS: Although EC initiators reduced CC use more than CC-exclusive users, only 29.7% reported complete CC cessation, and there was insufficient evidence of reduction in neonatal health complications relative to CC-exclusive users. Currently, ECs should not be considered a viable gestational smoking cessation strategy. IMPLICATIONS: Health agencies have identified a critical need for research evaluating the use of e-cigarettes in supporting prenatal smoking cessation. Using the U.S. Pregnancy Risk Assessment Monitoring System surveillance study data, we provide real-world evidence that prenatal e-cigarette initiation as a smoking cessation tool is used infrequently among pregnant CCs smokers. Most using e-cigarettes in the last 3 months of pregnancy also used CCs.

RESUMEN

INTRODUCTION: People with cancer who smoke exhibit greater cigarette dependence than people without cancer who smoke, a crucial factor in smoking cessation. Research is limited on the predictive potential of the Fagerström Test for Cigarette Dependence (FTCD) and the Heaviness of Smoking Index (HSI) on smoking abstinence in cancer patients undergoing smoking cessation treatment. AIMS AND METHODS: We analyzed data from 5934 cancer patients seeking smoking cessation treatment at The University of Texas MD Anderson Cancer Center (female 52.08%; Mean age = 55.52, SD = 11.17). We evaluated the predictive accuracy of FTCD and HSI on abstinence at 3, 6, and 9 months from the first consultation, and assessed the concordance between these tools in measuring cigarette dependence using Cohen's kappa test and different correlation and regression models. We also analyzed variations across sex at birth and race/ethnicity. RESULTS: Both the FTCD and the HSI demonstrated comparable predictive accuracy for smoking cessation at all follow-ups, with neither showing high accuracy (Areas Under the Curve scores around 0.6). Concordance analysis revealed substantial agreement between FTCD and HSI scores (Cohen's kappa ~ 0.7), particularly at lower levels of dependence. However, this agreement varied by race, with reduced concordance observed in non-Hispanic Blacks. CONCLUSIONS: Our results indicate that both the FTCD and HSI are effective tools for predicting smoking cessation in cancer patients, with the HSI offering a less burdensome assessment option. Nevertheless, the findings suggest the need for tailored approaches in assessing cigarette dependence that could predict smoking cessation more accurately, considering racial differences. IMPLICATIONS: The burden of assessing cigarette dependence in cancer care settings can be reduced by using the HSI instead of the FTCD. In addition, both instruments could be substantially interchanged and used for meta-analytic studies examining dependence and abstinence, but race/ethnicity should be considered.

RESUMEN

INTRODUCTION: This study aimed to (1) provide up-to-date estimates of how changes in the prevalence of e-cigarette use have been associated with changes in smoking cessation activities and use of licensed treatments among smokers in England and (2) explore any changes in these associations over time. METHODS: Data were aggregated quarterly on 67 548 past-year smokers between Q1-2007 and Q4-2022. Explanatory variables were the prevalence of (1) current e-cigarette use among smokers and (2) e-cigarette use during a quit attempt. Outcomes were rates of quit attempts and overall quits among past-year smokers, and the quit success rate and use of licensed treatments among those who made a quit attempt. RESULTS: The success rate of quit attempts increased by 0.040% (95% CI 0.019; 0.062) for every 1% increase in the prevalence of e-cigarette use during a quit attempt. No clear evidence was found for an association between current e-cigarette use and the quit attempt rate (Badj = 0.008 [95% CI -0.045; 0.061]) or overall quit rate (Badj = 0.063 [-0.031; 0.158]); or between use of e-cigarettes during a quit attempt and the overall quit rate (Badj = 0.030 [-0.054; 0.114]), use of prescription medication (varenicline/bupropion/nicotine replacement therapy [NRT]: Badj = -0.036 [-0.175; 0.102]), or use of over-the-counter NRT (Badj = -0.052 [-0.120; 0.015]). There was no clear evidence this pattern of associations has changed substantially over time. CONCLUSIONS: Changes in the prevalence of e-cigarette use in England through 2022 have been positively associated with the success rate of quit attempts but not clearly associated with the quit attempt rate, overall quit rate, or use of licensed smoking cessation treatments. IMPLICATIONS: If the association between the increase in e-cigarette use and the quit success rate is causal, then the use of e-cigarettes in quit attempts has helped in the region of 30 000 to 50 000 additional smokers in England to successfully quit each year since they became popular in 2013, over and above the number who were quitting before the advent of e-cigarettes.
