Decídetexto: Mobile cessation support for Latino adults who smoke. A randomized clinical trial.

BACKGROUND: Latino adults experience multiple barriers to healthcare access and treatment that result in tobacco-related disparities. Mobile interventions have the potential to deliver smoking cessation treatment among Latino adults, the highest users of mobile technologies. RESEARCH QUESTION: Is Decídetexto, a culturally accommodated mobile health intervention, more effective for smoking cessation compared to standard care among Latino adults who smoke? STUDY DESIGN AND METHODS: A two-arm parallel group randomized clinical trial (RCT) was conducted in Kansas, New Jersey, and New York between October 2018 and September 2021. Eligible Latino adults who smoke (n=457) were randomly assigned to Decídetexto or a standard care group. The primary outcome was biochemically verified 7-day smoking abstinence at week 24. Secondary outcomes included self-reported 7-day smoking abstinence at weeks 12 and 24, and uptake and adherence of nicotine replacement therapy (NRT). RESULTS: Participants mean age was 48.7 (SD 11.1) years, 45.2% were female, and 50.3% smoked ≥10 cigarettes per day. Two hundred twenty-nine participants were assigned to Decídetexto and 228 to standard care. Treating those lost to follow-up as participants who continued smoking, 14.4% of participants in the Decídetexto group were biochemically verified abstinent at week 24 compared to 9.2% in the standard care group (OR 1.66 [95% CI, 0.93-2.97], p=0.09). Treating those lost to follow-up as participants who continued smoking, 34.1% of the participants in the Decídetexto group self-reported smoking abstinence at week 24 compared to 20.6% of participants in the standard care group (OR 1.99 [95%, 1.31-3.03]; p<0.001). Analyzing only participants who completed the assessment at week 24, 90.6% (174/192) of participants in the Decídetexto group self-reported using NRT for at least one day compared to 70.2% (139/198) of participants in standard care (OR 4.10 [95% CI, 2.31-7.28]; p<0.01). INTERPRETATION: Among Latino adults who smoke, the Decídetexto intervention was not associated with a statistically significant increase in biochemically verified abstinence at week 24. However, the Decídetexto intervention was associated with a statistically significant increase in self-reported 7-day smoking abstinence at weeks 12 and 24, and uptake of NRT. This RCT provides encouragement for the use of Decídetexto for smoking cessation among Latino adults. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT03586596.

Feasibility and Preliminary Effects of a Social Media-Based Peer-Group Mobile Messaging Smoking Cessation Intervention Among Chinese Immigrants who Smoke: Pilot Randomized Controlled Trial.

BACKGROUND: Chinese immigrants experience significant disparities in tobacco use. Culturally adapted tobacco treatments targeting this population are sparse and the use is low. The low use of these treatment programs is attributed to their exclusive focus on individuals who are ready to quit and the wide range of barriers that Chinese immigrants face to access these programs. To support Chinese immigrant smokers at all levels of readiness to quit and address their access barriers, we developed the WeChat Quit Coach, a culturally and linguistically appropriate WeChat (Tencent Holdings Limited)-based peer group mobile messaging smoking cessation intervention. OBJECTIVE: This study aims to assess the feasibility, acceptability, and preliminary effects of WeChat Quit Coach. METHODS: We enrolled a total of 60 Chinese immigrant smokers in 2022 in New York City for a pilot randomized controlled trial (RCT) and a single-arm pilot test. The first 40 participants were randomized to either the intervention arm (WeChat Quit Coach) or the control arm (self-help print material) using 1:1 block randomization stratified by sex. WeChat Quit Coach lasted 6 weeks, featuring small peer groups moderated by a coach, daily text messages with text questions, and chat-based instant messaging support from the coach in response to peer questions. The next 20 participants were enrolled in the single-arm pilot test to further assess intervention feasibility and acceptability. All 60 participants were offered a 4-week supply of complimentary nicotine replacement therapy. Surveys were administered at baseline and 6 weeks, with participants in the pilot RCT completing an additional survey at 6 months and biochemical verification of abstinence at both follow-ups. RESULTS: Of 74 individuals screened, 68 (92%) were eligible and 60 (88%) were enrolled. The majority of participants, with a mean age of 42.5 (SD 13.8) years, were male (49/60, 82%) and not ready to quit, with 70% (42/60) in the precontemplation or contemplation stage at the time of enrollment. The pilot RCT had follow-up rates of 98% (39/40) at 6 weeks and 93% (37/40) at 6 months, while the single-arm test achieved 100% follow-up at 6 weeks. On average, participants responded to daily text questions for 25.1 days over the 42-day intervention period and 23% (9/40) used the chat-based instant messaging support. Most participants were satisfied with WeChat Quit Coach (36/39, 92%) and would recommend it to others (32/39, 82%). At 6 months, self-reported 7-day point prevalence abstinence rates were 25% (5/20) in the intervention arm and 15% (3/20) in the control arm, with biochemically verified abstinence rates of 25% (5/20) and 5% (1/20), respectively. CONCLUSIONS: WeChat Quit Coach was feasible and well-received by Chinese immigrants who smoke and produced promising effects on abstinence. Large trials are warranted to assess its efficacy in promoting abstinence in this underserved population.

Understanding the perceived benefits, barriers, and cues to action for lung cancer screening among Latinos: A qualitative study.

Introduction: Rates of lung cancer screening among Latinos remain low. The purpose of the study was to understand the perceived benefits, barriers, and cues to action for lung cancer screening among Latinos. Methods: Participants (N=20) were recruited using community-based recruitment strategies. Eligibility criteria included: 1) self-identified as Hispanic/Latino, 2) spoke English and/or Spanish, and 3) met the USA Preventive Services Task Force eligibility criteria for lung cancer screening. Interviews were conducted in Spanish and English, audio recorded, and transcribed verbatim. Using the health belief model, a qualitative theoretical analysis was used to analyze the interviews. Results: Participants' mean age was 58.3 years old (SD=5.8), half of the participants were female, 55% had completed high school or lower educational level, and 55% reported speaking more Spanish than English. All participants were currently smoking. Fourteen participants (70%) were unaware of lung cancer screening, and eighteen (90%) did not know they were eligible for lung cancer screening. Regarding lung cancer screening, participants reported multiple perceived benefits (e.g., smoking cessation, early detection of lung cancer, increased survivorship) and barriers (e.g., fear of outcomes, cost, lung cancer screening not being recommended by their clinician). Lastly, multiple cues to actions for lung cancer screening were identified (e.g., family as a cue to action for getting screened). Conclusions: Most Latinos who were eligible for lung cancer screening were unaware of it and, when informed, they reported multiple perceived benefits, barriers, and cues to action. These factors provide concrete operational strategies to address lung cancer screening among Latinos.

Exposure to E-Cigarette Marketing and Susceptibility to Future Vaping among Black and Latino Adolescents in the United States.

Evidence suggests an association between exposure to electronic cigarette (e-cigarette) marketing and e-cigarette use (vaping) among adolescents. However, there is limited evidence on exposure to e-cigarette marketing and susceptibility to future vaping, especially among Black and Latino adolescents. This study aimed to examine associations between exposure to e-cigarette marketing and susceptibility to future vaping among Black and Latino adolescents in the United States (US). Participants (N = 362; equal representation between Black and Latino adolescents) completed a baseline assessment (available in English and Spanish) including sociodemographic characteristics (e.g., racial/ethnic group, age, gender, sexual orientation, etc.), exposure to e-cigarette marketing, and susceptibility to future vaping. Exposure to e-cigarette marketing was recoded and organized into two categories (high exposure = 2 to 3; low exposure = 0 to 1). Cochran-Mantel-Haenszel tests were used to evaluate the association between exposure to e-cigarette marketing and susceptibility to future vaping, stratified by racial/ethnic group. Multiple logistic regressions assessed the association between exposure to e-cigarette marketing and susceptibility to future vaping, controlling for gender, sexual orientation, grade, and academic performance within each racial/ethnic group. Black adolescents reported significantly higher frequencies of exposure to e-cigarette marketing (p = 0.005). A significant interaction was found between exposure to e-cigarette marketing and racial/ethnic group (X2 (1) = 6.294, p = 0.012). Among Black adolescents, high exposure to e-cigarette marketing (vs. low exposure) was associated with a higher probability of susceptibility to future vaping (OR: 2.399, 95% CI 1.147-5.021, p = 0.020). For Latino adolescents, exposure to e-cigarette marketing was not associated with susceptibility to future vaping (OR: 0.503, 95% CI 0.245-1.03, p = 0.062). Future studies should evaluate how and where adolescents are exposed to e-cigarette marketing. Prevention efforts must include the implementation of effective counter-marketing campaigns and the reduction of exposure to e-cigarette marketing among Black and Latino adolescents.

Recruiting Latino young adults into a vaping cessation study via social media: Feasibility and cost analysis.

INTRODUCTION: This study aims to assess the feasibility and cost of recruiting young Latino adults (aged 18-25 years) to participate in a vaping cessation study via social media and to describe the baseline characteristics of participants enrolled via social media. METHODS: Paid advertisements were launched using the Meta Ads platform, which serves ads to users on Facebook and Instagram. Key measures of audience targeting included ages 18-25 years, all genders, and the following interests: 'electronic cigarettes', 'vape', 'Latin pop', and 'Latin music'. The advertisements invited young Latino adults to join a text messaging vaping cessation study. By clicking on the advertisements, interested individuals were directed to a website to fill in a contact form. The study team contacted individuals who filled in the form, assessed them for study eligibility, and, if eligible, enrolled them in the study. RESULTS: A total of 164 individuals completed the contact form, and 26 were successfully enrolled in the study. The enrollment efficiency ratio was 15.9% (26/164). The cost per enrollment was US$94.14. The participants' mean age was 22.7 years (SD=1.6). Half of the participants (50%) were male, 38.5% were female, and 11.5% were gender non-conforming/non-binary. Two-thirds of the participants (69.2%) were born in the US, 23.1% in Puerto Rico, and 7.7% in Mexico. Eight participants (30.7%) selected Spanish as their language of preference. In terms of the type of vaping device, 16 participants (61.5%) indicated using disposables, 6 (23.1%) cartridges/pods, and 4 (15.4%) tanks/refillable. Sixteen participants (61.5%) reported using marijuana in e-cigarettes. Six participants (23.1%) had high e-cigarette dependence. Twenty participants (76.9%) had attempted to quit e-cigarettes in the past year. CONCLUSIONS: It is feasible to recruit young Latino adults for a vaping cessation study via social media. Social media offers a relatively low-cost approach to recruiting a diverse sample of Latino young adults who vape.

Evaluating the psychometric properties of the Hispanic Stress Inventory-2 Simplified version among a diverse sample of Latinos who smoke.

OBJECTIVE: Acculturation stress can negatively impact Latinos immigrant mental and physical health related behaviors such as smoking. It is essential to have validated and updated instruments that allow the evaluation of acculturation stress on this population. This study aims to evaluate the psychometric properties of an abbreviated version of the Hispanic Stress Inventory Version 2 (HSI2) immigration scale among Latinos who smoke. METHODS: The study consisted of a secondary data analysis from a baseline assessment of Decídetexto, a mobile health (mHealth) smoking cessation randomized clinical trial. Of 457 Latinos included in the parent study, 352 immigrants who smoke were included. Construct validity was analyzed by completing a Pearson correlation coefficient matrix. Structural validity was analyzed using an Exploratory Factor Analysis (EFA). Cronbach alpha analysis was used to estimate the internal consistency of the items constituting a factor. RESULTS: The results included an abbreviated version of the HSI2 including 52 items. From the Pearson correlation coefficient matrix with a cutoff point of 0.4, 22 of the 52 items were excluded. From the Pearson correlation coefficient matrix with a cutoff point of 0.4, 22 items were excluded. Exploratory Factor Analysis (EFA) results in six factors extracted, explaining 69.1% of the variance. According to the EFA, two items were relocated in different factors from the original scale. The HSI2 30 items scale reflected excellent reliability with a Cronbach's alpha coefficient of 0.93. The six factors reflect acceptable to excellent reliability, ranging from 0.77-0.93 across factors. The median for the HSI2 total score was 34.00 (25-45) out of a possible total score of 150. CONCLUSION: Results confirmed acceptable psychometric properties of the HSI2 simplified 30-item version and provided a reliable and shorter measure of acculturation stress for Latinos groups. Having a valid and reduced measure of acculturation stress is the first step in understanding diverse ethnic groups of Latinos that are at higher risk of presenting health risk behaviors such as smoking. The present results provided the possibility of assessing the impact of acculturation stress among adults who smoke.

Actívatexto: Feasibility and Acceptability of a Mobile Intervention That Promotes Smoking Cessation and Physical Activity among Latinos.

The purpose of this study was to assess the feasibility and acceptability of a mobile intervention that promotes smoking cessation and physical activity among Latinos living in the United States. Twenty Latino adults who smoked and did not meet recommended levels of physical activity were recruited using community-based recruitment strategies. Participants received Actívatexto, a theory-based, culturally accommodated, 12-week text messaging intervention (available in English and Spanish) that promotes smoking cessation and physical activity. Actívatexto integrates four components: (i) a text messaging program, (ii) a wearable device, (iii) an online dashboard where the research team manages participants' incoming and outgoing data from both the text messaging program and wearable device, and (iv) nicotine replacement therapies (NRT). We assessed self-reported 7-day point prevalence smoking abstinence at month 3, weekly minutes of moderate to vigorous physical activity (MVPA), pharmacotherapy adherence, and satisfaction. At baseline, participants' mean age was 47.3 years old (SD 16.0), 55% of participants were female, and 60% indicated that Spanish was their language of preference. Seventy-five percent of participants smoked 1-10 cigarettes daily and 35% smoked their first cigarette within 5 minutes after waking up. At month 3, 14 participants (70%) self-reported 7-day point prevalence smoking abstinence (90% follow-up rate). Fitbit-assessed mean minutes of MVPA per week increased from 113 (SD 127; range: 0-399) at week 1 to 177 (SD 163; range: 0-513) at month 3 (P = 0.15). Sixteen participants (88.9%, 16/18) reported NRT use in the past 90 days. Most participants reported being extremely satisfied or satisfied with the intervention (88.9%, 16/18). SIGNIFICANCE: Actívatexto resulted in a noteworthy cessation rate at month 3 (70%), increased mean weekly minutes of MVPA, produced high use of NRT, and was well received by participants. Additional testing in a randomized clinical trial is warranted to assess the efficacy of the intervention.

Electronic Decision-Making Tool for Smoking Cessation (Pare de Fumar Conosco) Versus Standard of Care: A Cost-Effectiveness Analysis.

OBJECTIVES: The study aimed to evaluate the cost-effectiveness of the Pare de Fumar Conosco software compared with the standard of care adopted in Brazil for the treatment of smoking cessation. METHODS: In the cohort of smokers with multiple chronic conditions, we developed an decision tree model for the benefit measures of smoking cessation. We adopted the perspectives of the Brazilian Unified Health System and the service provider. Resources and costs were measured by primary and secondary sources and effectiveness by a randomized clinical trial. The incremental cost-effectiveness ratio (ICER) was calculated, followed by deterministic and probabilistic sensitivity analyses and deterministic and probabilistic sensitivity analyses. No willingness to pay threshold was adopted. RESULTS: The software had a lower cost and greater effectiveness than its comparator. The ICER was dominant in all of the benefits examined (-R$2 585 178.29 to -R$325 001.20). The cost of the standard of care followed by that of the electronic tool affected the ICER of the benefit measures. In all probabilistic analyses, the software was superior to the standard of care (53.6%-82.5%). CONCLUSION: The Pare de Fumar Conosco software is a technology that results in cost savings in treating smoking cessation.

Development of a Vaping Cessation Text Messaging Intervention for Latino Young Adults: A Participatory Research Approach.

OBJECTIVE: Describe the participatory research procedures of developing Kick Vaping, a vaping cessation text messaging intervention for Latino young adults, available in English and Spanish. METHODS: Using community-based recruitment strategies, we convened a Community Advisory Board (CAB) of eight Latino young adults (ages 18-25) with different vaping experiences (never users, ex-users, and current users of e-cigarettes). Members held a series of working meetings to adapt Decídetexto, a smoking cessation text messaging intervention, for vaping cessation. Members provided iterative feedback on the text messages until reaching a consensus on content. Messages were translated from English to Spanish following a committee approach. Readability assessments were used to evaluate the legibility of the text messages. RESULTS: At baseline, members' mean age was 22.6 years old (SD 3.1), 75% were female, and 50% used both English and Spanish equally. Three members (37.5%) were ex-users and one member (12.5%) was a current user of e-cigarettes. 18 meetings provided sufficient opportunities for iterative feedback on the text messages for developing the intervention. The Kick Vaping intervention consists of 208 text messages. Readability scores of the text messages in English were equivalent to fourth and fifth grade, and in Spanish were equivalent to easy and somewhat easy. CONCLUSION: It is feasible and practical to build participatory research among Latino young adults focused on vaping cessation. Members of the CAB added innovation and creativity to the development of the vaping cessation text messaging intervention. Future research is needed to evaluate the impact of the intervention on vaping cessation.

Prevalence and correlates of current cigarette smoking among transgender women in Argentina.

Objective: To assess the prevalence of current cigarette smoking among transgender women in Argentina, and to examine the unique associations of current cigarette smoking with demographic and psychosocial factors. Methods: This study is a secondary data analysis of the TransCITAR - a prospective cohort study of transgender individuals living in Buenos Aires, Argentina - baseline data. The baseline survey collected information on sociodemographic characteristics, perceived health status, depressive symptoms, suicide attempts, current cigarette smoking, alcohol use disorder, and substance use. Participants were also asked about lifetime experiences of physical and sexual violence perpetrated by partners, clients and/or the police, and experiences of gender identity stigma in the past year from healthcare workers and the police. Lastly, participants were asked if they had ever been arrested. Fisher's exact test was used to compare proportions in categorical variables and student t-test was used for continuous variables. Significant associations with current cigarette smoking were tested in a logistic regression model adjusted for all significant associations. Results: A total of 41.7% of participants (n = 393) reported current cigarette smoking. Compared to their non-smoking counterparts, participants who reported current cigarette smoking (1) had completed less education, (2) were more likely to be born in Argentina, (3) more likely to had migrated to Buenos Aires from other parts of the country, (4) more likely to report a history of sex work, (5) more likely to perceive their health as excellent, (6) more likely to screen positive for hazardous alcohol drinking, (7) more likely to report any substance and cocaine use in the past year, (8) more likely to experience gender identity stigma from the police in the past year, and (9) more likely to being arrested in their lifetime (all p's < 0.05). After controlling for all significant associations, education level of less than high school (AOR = 1.79, 95% CI 1.02-2.12), hazardous drinking (AOR = 2.65, 95% CI 1.30-5.37), and any substance use in the last year (AOR = 2.14, 95% CI 1.16-3.94) were positively and independently associated with current cigarette smoking. Conclusion: Among transgender women in Argentina, current cigarette smoking was more than double the rate for cisgender women. Current cigarette smoking was associated with education, hazardous drinking, and any drug use. These results will inform future smoking cessation interventions among transgender women in Argentina.

Role of genetic susceptibility in nicotine addiction and chronic obstructive pulmonary disease

Abstract Chronic obstructive pulmonary disease (COPD) is a leading cause of morbidity and mortality in developed countries. Although cigarette smoking is the major risk factor, only 10-20% of smokers develop COPD. The extent of cigarette smoking (pack-years and smoking duration) accounts for only 15% of the variation in lung function, indicating that differences in susceptibility to COPD must exist. We provide an overview of the complexity of nicotine addiction and COPD, with special attention to the involvement of genetic factors. The following aspects are discussed in the present article: (1) epidemiology in Mexico and (2) a review of the published literature on genetic association studies using the National Center for Biotechnology Information database of the United States as a search tool. COPD is unique among complex genetic diseases where an environmental risk factor is known and the level of exposure can be documented with some precision. The high morbidity and mortality associated with COPD and its chronic and progressive nature has prompted the use of molecular genetic studies to identify susceptibility factors for the disease. Biomedical research has a remarkable set of tools to aid in the discovery of genes and polymorphisms. We present a review of the most relevant genetic associations in nicotine addiction and COPD.

Enhancing smoking cessation in Mexico using an e-Health tool in primary healthcare / Uso de una herramienta electrónica para la cesación del tabaquismo en el primer nivel de atención en México

Abstract: Objective: To evaluate an e-Health tool designed to enhance smoking cessation in Mexico in primary healthcare. Materials and methods: Smokers 18 years of age and older were recruited in the waiting room of two primary healthcare clinics in Mexico City. Participants used an e-Health smoking cessation tool that included smoking-related assessments, education on pharmacotherapy, and motivational videos. A follow-up assessment was conducted at 12 weeks week on smoking status. Logistic regression models were performed to identify factors associated with smoking cessation or consumption reduction. Results: A total of 132 smokers were enrolled in the study. At follow-up, 23.5% of participants self-reported smoking cessation. Among those who did not quit smoking, 65.0% decreased the number of cigarettes. Factors associated significantly with smoking cessation were: being a non-daily smoker, being interested in quitting smoking, having low level of physical dependence, and participating in cessation treatment. Conclusions: The e-Health tool produced a high rate of smoking cessation. Better outcomes are obtained when this tool is used with conventional cessation programs.
