Feasibility and Engagement of a Mobile App Preparation Program (Kwit) for Smoking Cessation in an Ecological Context: Quantitative Study.

BACKGROUND: Mobile health apps can facilitate access to effective treatment and therapeutic information services. However, the real-world effectiveness of mobile apps for smoking cessation and their potential impact in everyday settings remain unclear. OBJECTIVE: In an ecological context, this study aimed to estimate the engagement rate of a mobile app-based smoking cessation preparation program and its potential impact on users' willingness, ability, and readiness to quit smoking. METHODS: A total of 2331 "organic users" (ie, users who discover and install a mobile app on their own, without any prompts) chose 1 of 2 program versions of the mobile app (Kwit): the basic version or the premium version. Both versions were identical in design, with 4 more evidence-based content items and strategies in the premium version. Outcomes were analyzed based on automated data registered in the app (engagement rate, motivation to quit, motivation type, motivation levels, and satisfaction level). Mann-Whitney and χ2 tests were used to compare the results of both groups. RESULTS: As expected, in the ecological context, a high dropout rate was observed at different moments. A significant difference was observed between the 2 versions (n=2331; χ21=5.4; P=.02), with a proportionally higher engagement rate in the premium version (premium=4.7% vs basic=2%). Likewise, differences were also observed between the 2 groups in terms of reasons to quit (n=2331; χ24=19; P≤.001; V=0.08), motivation type (n=2331; χ27=14.7; P=.04), and motivation level. Users of the app's premium version more frequently reported "well-being" (23.3% vs 17.9%) and "planning a pregnancy" (7.4% vs 4.4%) as their primary reasons for quitting smoking compared to those with the basic version. Moreover, they reported being more likely to be driven in the smoking cessation process by intrinsic motivation (premium=28% vs basic=20.4%), as well as feeling significantly more willing (z score=156,055; P≤.001; Cohen d=0.15), able (z score=172,905; P=.04; Cohen d=0.09), and ready (z score=166,390; P=.005; Cohen d=0.12) to stop smoking than users who had the basic version before completion of the preparation program. Among participants who finished each version of the program (premium: 9/189, 4.8%; basic: 47/2142, 2.19%), significant improvements in motivation levels were observed in both groups, although in different areas for each group (willingness levels for the premium group and ability for the basic group). CONCLUSIONS: These results suggest that even in ecological contexts where engagement rates are meager, the Kwit preparation program can address ambivalence by increasing willingness to change, self-confidence, and readiness to quit among its users, especially those who feel less able to do so. Further development and evaluations are needed to better understand determinants for regular mobile health apps.

Association of perceived neighborhood air quality problems with attempt to quit cigarette smoking: a cross-sectional study in Texas.

Background: Cigarette smoking is the major preventable cause of premature deaths in the United States. Attempting to quit smoking is an important step toward smoking cessation. Although it has been studied extensively, limited information on the association between attempts to quit smoking and neighborhood air quality problems is available. Therefore, we examined the association between attempts to quit smoking in the past year and perceived neighborhood air quality problems among adult Texans who smoke. Methods: In 2018, a cross-sectional multistage area probability design-based survey was administered to collect sociodemographic, behavioral, and health-related information from a representative sample of 2050 Texas residents. The current study included 486 adult respondents who reported smoking within the past 12 months. The association between attempts to quit smoking and perceived neighborhood air quality (measured by self-reported problems with neighborhood air quality) was examined using a population-weighted multivariable logistic regression analysis. Results: Overall, 60.7% of the 486 respondents attempted to quit cigarette smoking. The prevalence of attempting to quit was 74.6% for those reporting perceived neighborhood air quality problems. In the multivariable analysis, a higher likelihood of attempting to quit smoking was found among individuals with perceived neighborhood air quality problems (AOR: 1.906 [1.104-3.289]) and those who were married or living as married (AOR: 1.876 [1.161-3.033]). The likelihood of attempts to quit smoking was lower among males (AOR: 0.629 [0.397-0.995]) and decreased with age (AOR: 0.968 [0.951-0.984]). Discussion: The perceived neighborhood air quality problems were found to independently predict attempts to quit cigarette smoking in Texas. To encourage quitting smoking among individuals living in neighborhoods with poor air quality, such neighborhoods should receive tailored and evidence-based interventions to improve community education, social support, and healthcare professionals' assistance to quit smoking.

Factors influencing smoking cessation attempts and success in Iranian male adults: national survey data.

BACKGROUND: Smoking cessation is a dynamic process that often involves a series of unsuccessful quit attempts before long-term abstinence is achieved. To implement interventions that lead to long-term abstinence, it will be necessary to understand the determinants of smoking cessation. Therefore, the main objective of the present study was to determine the effect of factors influencing both smoking cessation attempts and successful smoking cessation in the general population of Iran. METHODS: The data of 1293 participants whose information was obtained through a national cross-sectional study entitled "Survey of Risk Factors of Noncommunicable Diseases in 2016" were analyzed. There were three response levels: "quit attempt and successful quit", "quit attempt and unsuccessful quit", and "no quit attempt and unsuccessful quit". A multinomial logistic regression model was used to assess the effect of covariates on response. RESULTS: The mean (sd) age of all participants was 47.21 (13.65) years. According to the results, 883 people (68.29%) did not attempt to quit smoking, and of those who attempted to quit smoking, only 64 (15.61%) men were successful. The factors of living in an urban area (OR = 1.71) and past smoking intensity (OR = 1.967) were associated with no quit attempt and unsuccessful quitting. In addition, physician recommendation to quit smoking was a protective factor for no quit attempt and unsuccessful quit (OR = 0.599). Alcohol consumption was also a protective factor against successful quitting for both attempters (OR = 0.351) and nonattempters (OR = 0.359). CONCLUSIONS: Tobacco control programs should be implemented with a greater focus on heavy smokers and alcohol users. In addition, the role of health professionals in encouraging smokers to quit smoking should not be ignored.

Is social media our new quitline? A descriptive study assessing youtube coverage of tobacco cessation.

Background: Tobacco use and exposure are leading causes of morbidity and mortality worldwide. In the past decade, educational efforts to reduce tobacco use and exposure have extended to social media, including video-sharing platforms. YouTube is one of the most publicly accessed video-sharing platforms. Purpose: This cross-sectional descriptive study was conducted to identify and describe sources, formats, and content of widely viewed YouTube videos on smoking cessation. Methods: In August to September 2023, the keywords "stop quit smoking" were used to search in YouTube and identify 100 videos with the highest view count. Results: Collectively, these videos were viewed over 220 million times. The majority (n = 35) were posted by nongovernmental/organization sources, with a smaller number posted by consumers (n = 25), and only eleven were posted by governmental agencies. The format used in the highest number of videos was the testimonial (n = 32 videos, over 77 million views). Other popular formats included animation (n = 23 videos, over 90 million views) and talk by professional (n = 20 videos, almost 43 million views). Video content included evidence-based and non-evidence-based practices. Evidence-based strategies aligned with U.S. Public Health Service Tobacco Treatment Guidelines (e.g. health systems approach in tobacco treatment, medication management). Non-evidence-based strategies included mindfulness and hypnotherapy. One key finding was that environmental tobacco exposure received scant coverage across the videos. Conclusions: Social media such as YouTube promises to reach large audiences at low cost without requiring high reading literacy. Additional attention is needed to create videos with up-to-date, accurate information that can engage consumers.

To Investigate the Influence of Smoking Cessation Intention and Common Downstream Variants of HDAC9 Gene on Large Artery Atherosclerotic Cerebral Infarction.

Objective: To investigate the association of smoking cessation intention and single nucleotide polymorphism of HDAC9 gene with LAA-S in Han people in Hainan province. Methods: A case-control study was conducted. Six single nucleotide polymorphisms (SNPS) of HDAC9 gene were genotyped by SNPscan genotyping technique in 248 patients with LAA-S and 237 controls in Hainan Han population. SNP loci (rs10227612, rs12669496, rs1548577, rs2074633, rs2526626, and rs2717344) were genotyped, and the genotype and allele frequencies were compared between the case and control group. At the same time, the distribution of smoking between the case and control group was compared, and the 3-year and 7-year follow-up smoking cessation between the case and control group was compared, so as to find out the effects of smoking cessation intention and HDAC9 SNP on LAA-S. Results: (1) The GT genotype at rs10227612, GG genotype at rs2717344, and GA genotype at rs1548577 in the case group were significantly higher than those in the control group, and the differences were statistically significant. (2) There were significant differences in the distribution of smoking between the case and control group (P < 0.05), and there were significant differences in the smoking cessation after 3 years and 7 years of follow-up between the case and control group (P < 0.05). The intention to quit smoking was positively correlated with the incidence of LAA-S. Conclusion: (1) The rs10227612, rs1548577, rs2074633, rs2717344 of HDAC9 gene may be significantly related to atherosclerotic cerebral infarction of great arteries in Hainan Han population, while rs12669496 and rs2526626 may not be related. (2) According to the statistics of smoking in the case and control group, smoking was related to large artery atherosclerotic cerebral infarction, and the intention to quit smoking was a very important factor affecting the success of smoking cessation.

Effect of Ramadan fasting on changes in smoking and vaping behaviors and withdrawal symptoms severity: a cross-sectional study.

BACKGROUND: Ramadan fasting, an obligatory duty for adult Muslims, entails refraining from eating, drinking, smoking, and vaping from dawn until sunset. Throughout Ramadan, people accept major changes to daily routines. Consequently, Ramadan is associated with abstinence symptoms and changes in smoking or vaping behavior. AIM: The study aims to assess the presence of withdrawal symptoms and its severity, as well as smoking or vaping behavior change and its determinants during Ramadan fasting. METHODS: A cross-sectional study was conducted during Ramadan in 2023. Data were collected online using a Google form, including questionnaires assessing socio-demographic data, nicotine dependence using Fagerstrom Test for Nicotine Dependence, vaping and shisha smoking, presence and severity of physiological and psychological withdrawal symptoms and its coping strategies. Smoking and vaping behavioral change during Ramadan and its contributing factors were also evaluated. RESULTS: A total of 251 participants (96% males), mean age ± standard deviation (33 ± 12.1) were surveyed. Withdrawal symptoms were reported among 70.5%, however, their severity was generally low both physiologically and psychologically. Education, nationality, smoking duration, nicotine dependence, and the amount of consumed E-liquid per day were the independent predictors of withdrawal symptoms presence. Attempts to quit smoking and vaping were reported by 54.6% of the participants; young age and higher educational levels were the factors associated with more quitting attempts. CONCLUSIONS: The withdrawal symptoms severity linked to Ramadan fasting is minimal. Many smokers and vapers made attempts to quit during Ramadan. Ramadan presents a chance for smoking and vaping cessation with some behavioral support.

Impact of switching from cigarette smoking to tobacco heating system use on biomarkers of potential harm in a randomized trial.

BACKGROUND: Smoking cessation reduces the risk of developing smoking-related diseases. Although smoking prevalence has declined, many continue smoking cigarettes. Switching completely to smoke-free alternatives like the Tobacco Heating System (THS) 2.2-a heated tobacco product for which there is evidence demonstrating significantly reduced formation and exposure to harmful chemicals compared to cigarettes-has the potential to reduce the harm caused by continuing to smoke cigarettes. METHODS: We conducted a 6-month clinical study (NCT02396381) with a 6-month extension (NCT02649556), initially randomizing 984 adult smokers to continue smoking or switch to THS (non-mentholated), of which 672 continued into the extension study. Endpoints were evaluated at baseline and at 3, 6, and 12 months. We longitudinally assessed biomarkers of potential harm (BoPHs) known to be reversible upon smoking cessation as indicators of pathways involved in the pathogenesis of cardiovascular or respiratory diseases and carcinogenicity. The need to cough and safety profile were also assessed. Impact on eight key BoPHs was used as a proxy to evaluate harm reduction potential. RESULTS: At 12 months, comparison of BoPH levels between the predominant THS use and cigarette smoking groups showed a positive effect in favor of switching, partially or in full, to THS. CONCLUSION: These results provide additional evidence of the harm reduction potential of THS for smokers who would otherwise continue smoking, but they need to be verified in long-term confirmatory studies.

Efficacy of the QuitSure App for Smoking Cessation in Adult Smokers: Cross-Sectional Web Survey.

BACKGROUND: Cigarette smoking remains one of the leading causes of preventable death worldwide. A worldwide study by the World Health Organization concluded that more than 8 million people die every year from smoking, tobacco consumption, and secondhand smoke. The most effective tobacco cessation programs require personalized human intervention combined with costly pharmaceutical supplementation, making them unaffordable or inaccessible to most tobacco users. Thus, digital interventions offer a promising alternative to these traditional methods. However, the leading smartphone apps available in the market today have either not been studied in a clinical setting or are unable to match the smoking cessation success rates of their expensive offline counterparts. We would like to understand whether QuitSure, a novel smoking cessation app built by Rapidkart Online Private Limited, is able to bridge this efficacy gap and deliver affordable and effective smoking cessation at scale. OBJECTIVE: Our objective was to do an initial exploration into the engagement, efficacy, and safety of QuitSure based on the self-reported experiences of its users. Outcomes measured were program completion, the effect of program completion on smoking behavior, including self-reported cessation outcomes, and negative health events from using the app. METHODS: All QuitSure registered users who created their accounts on the QuitSure app between April 1, 2021, and February 28, 2022, were sent an anonymized web-based survey. The survey results were added to their engagement data on the app to evaluate the feasibility and efficacy of the app as a smoking cessation intervention. The data were analyzed using descriptive statistics (frequencies and percentages) and the χ2 test of independence. RESULTS: In total, 1299 users who had completed the QuitSure program submitted the survey and satisfied the inclusion criteria of the study. Of these, 1286 participants had completed the program more than 30 days before filling out the survey, and 1040 (80.1%, 95% CI 79.1%-82.6%) of them had maintained prolonged abstinence for at least 30 days after program completion. A majority of participants (770/891, 86.4%) who were still maintaining abstinence at the time of submitting the survey did not experience any severe nicotine withdrawal symptoms, while 41.9% (373/891) experienced no mild withdrawal symptoms either. Smoking quantity prior to completing the program significantly affected quit rates (P<.001), with heavy smokers (>20 cigarettes per day) having a lower 30-day prolonged abstinence rate (relative risk=0.91; 95% CI 90.0%-96.2%) compared to lighter smokers. No additional adverse events outside of known nicotine withdrawal symptoms were reported. CONCLUSIONS: The nature of web-based surveys and cohort selection allows for extensive unknown biases. However, the efficacy rates of survey respondents who completed the program were high and provide a case for further investigation in the form of randomized controlled trials on the QuitSure tobacco cessation program.

Behavioral Activation Mobile App to Motivate Smokers to Quit: Feasibility and Pilot Randomized Controlled Trial.

BACKGROUND: Behavioral activation (BA) is an evidence-based treatment for depression that fosters engagement in values-based activities to increase access to positive reinforcement. Depressed mood has been shown to hinder smoking cessation. OBJECTIVE: This study determined the feasibility and preliminary efficacy of a mobile app to motivate smokers to quit by using BA and integrating motivational messages to quit smoking. METHODS: Adult smokers (N=56; mean age 34.5, SD 9.52 years) who were not ready to quit smoking within 30 days were recruited from advertisements and randomized to either 8 weeks of the BA app (set 2 values-based activities per week+motivational messages+feedback on changes in smoking, mood, and values-based activities) or the control group (no app; received resources for quitting smoking). All participants completed the baseline and end-of-treatment web-based questionnaires. Controls also completed weekly web-based assessments, and BA app participants completed assessments through the app. RESULTS: There were no dropouts and only 2 participants in each condition did not complete the end-of-treatment questionnaire. The results demonstrated that it is feasible to recruit smokers who are unmotivated to quit into a smoking cessation induction trial: 86% (57/66) of eligible participants were randomized (BA app: n=27; control: n=29). Participants reported high levels of satisfaction: 80% (20/25) of participants said they would recommend the BA app, there were moderate-to-high scores on the Mobile App Rating Scale, and 88% (22/25) of participants rated the app 3 stars or higher (out of 5). There were high levels of BA app engagement: 96% (26/27) of participants planned activities, and 67% (18/27) of participants planned 7 or more activities. High engagement was found even among those who were at the highest risk for continued smoking (low motivation to quit, low confidence to quit, and high negative affect). The results provided support for the hypothesized relationships between BA constructs: greater pleasant activity completion was associated with greater positive affect (b=0.37, SE 0.21; 95% CI -0.05 to 0.79; P=.08), and greater positive affect tended to predict fewer cigarettes smoked the next day (b=-0.19, SE 0.10; 95% CI -0.39 to 0.01; P=.06). Additionally, a greater number of activities planned was associated with lower negative affect (b=-0.26, SE 0.15; 95% CI -0.55 to 0.04; P=.09). Overall, 16% (4/25) of BA app participants set a quit date versus 4% (1/27) among controls, and there were promising (but not significant) trends for motivation and confidence to quit. CONCLUSIONS: The findings suggest that a mobile app intervention can be made appealing to smokers who are unmotivated to quit by focusing on aspects most important to them, such as mood management. This theory-based intervention has shown some initial support for the underlying theoretical constructs, and further efficacy testing is warranted in a fully powered trial.

Efectos de una Charla Antitabaco en Adolescentes Fumadores de Colegios Públicos y Privados en la Región Metropolitana de Santiago de Chile / Effects of an Anti-Smoking talk on Adolescent Smokers in Public and Private Schools in the Metropolitan Region of Santiago de Chile

Introducción. El tabaquismo es responsable de una gran cantidad de muertes en el mundo, la gran prevalencia del tabaquismo entre adolescentes, así como la baja edad de inicio del consumo, genera preocupación y la necesidad de implementar intervenciones específicas a esta población. Objetivo. Evaluar los efectos de una charla antitabaco en adolescentes de colegios públicos y privados en la Región Metropolitana de Santiago. Métodos. Estudio cuantitativo cuasi-experimental, se realizó una charla antitabaco en dos colegios (público y privado), se evaluó la motivación para dejar de fumar con el Test de Richmond en una muestra de 13 estudiantes pre y post charla. Resultados. hubo una mejora en los puntajes de Richmond post charla en ambos colegios, siendo mayor en el colegio público, sin embargo, la diferencia no fue estadísticamente significativa (p=0,09). Discusión. La evidencia respalda la efectividad de las charlas antitabaco. Existe una relación entre nivel socioeconómico y tabaquismo, sin embargo, no hay otros estudios que comparen la efectividad en los distintos estratos sociales. Se reconocen limitaciones del estudio como el tamaño de la muestra y el muestreo no aleatorio, se recomiendan nuevos estudios que incluyan otras variables. Conclusiones. A pesar de limitaciones del estudio, se respalda la implementación de charlas antitabaco en entornos educativos, enfatizando la necesidad de adaptar estrategias a contextos socioeconómicos específicos para mejorar la salud pública.

Background. Introduction: Smoking is responsible for a significant number of deaths worldwide, and the high prevalence of smoking among adolescents, as well as early age of onset, raises concerns, and the need of targeted interventions for this group. The aim of this study was to assess the effects of an anti-smoking talk on students from public and private schools in the Metropolitan Region of Santiago. Methods. A quasi-experimental quantitative study involving an anti-smoking talk in two schools (public and private) assessed the motivation to quit smoking using the Richmond Test in a sample of 13 students pre and post the talk. Results. There was an improvement in Richmond scores post-talk in both schools, with a greater increase observed in the public school. However, the difference was not statistically significant (p=0.09). Discussion. The evidence supports the effectiveness of anti-smoking talks. A relationship between socioeconomic status and smoking exists, yet there are no studies comparing effectiveness across different socioeconomic strata. Study limitations, such as sample size and non-random sampling, are acknowledged, and further research incorporating additional variables is recommended. Conclusions. Despite study limitations, advocating for the implementation of anti-smoking talks in educational settings is supported, emphasizing the need to adapt strategies to specific socioeconomic contexts to enhance public health.
