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.

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.

The influence of health literacy and knowledge about smoking hazards on the intention to quit smoking and its intensity: an empirical study based on the data of China's health literacy investigation.

OBJECTIVE: This study explored the relationship between smokers' health literacy, knowledge of smoking hazards, and their intention to quit. METHODS: Based on data from the 2019 Health Literacy and Tobacco Use Surveillance among residents of a city in Zhejiang Province, 1120 male smokers were screened. Differential tests were used to analyze whether smokers with varying levels of health literacy and knowledge about smoking hazards differed in their intention to quit smoking and the intensity of their intention. A multi-factor logistic regression model was constructed to explore the extent of these differences. RESULTS: Only 24.8% of smokers had higher health literacy. Among smokers, those with an intention to quit had a higher health literacy level compared to those without such intention (32.7% vs. 17.0%, p < 0.001). Health literacy levels did not differ significantly between groups with different intensity of intention to quit (34.2% vs. 31.9% vs. 30.1%, p = 0.435). About 48.7% of the smokers a higher level of knowledge about smoking hazards. It was more prevalent in the intent to quit group compared to the no intent to quit group (54.0% vs. 43.4%, p < 0.001), and the low intent to quit group had lower knowledge compared to the moderate and high intent to quit groups (49.1% vs. 56.6% vs. 63.4%, p = 0.011). After adjusting for other influences, smokers with lower health literacy were less likely to have intention to quit (OR = 0.659, p = 0.016). And the association between knowledge about smoking hazards and whether smokers have the intention to quit is no longer significant, but it significantly affects the intensity of the intention to quit among smokers who already have the intention (OR = 0.623, p = 0.005). CONCLUSION: General health literacy may play a role in facilitating smokers' progression from the stage of no intent to quit to one of intent to quit, but a more specific understanding of the harms of smoking may be needed to increase the strength of intent to quit.

The association between viewing cigarette health warning labels and intention to quit smoking among Chinese adult smokers: support for including health outcome content and culturally specific messages.

BACKGROUND: Tailored themes of pictorial health warning labels (HWLs) that considers specific cultural dimensions and within a specific policy/historical context can motivate behavior change, such as provoking smokers to think about quitting. Currently in China, the HWLs on cigarettes are text-only. This study designed pictorial HWLs using different themes to explore and examine the association between viewing pictorial HWLs and participants' intention to quit smoking. The themes included: (1) Self-harm from using cigarettes, (2) Harming family or children with secondhand smoke, (3) Complying with existing smoke-free policies, and (4) Cigarette gift giving practices. METHODS: A cross-sectional randomized experimental survey was conducted among 1,625 smokers in Beijing (n = 545), Shanghai (n = 541), and Shenzhen (n = 539) during 2017. Before and after viewing eight pictorial HWLs of one theme, participants were asked if they had plans to quit smoking within the next month, within the next 6 months, beyond the next 6 months, or not at all. Ordinal logistic regression, Wilcoxon and Chi-square tests were used to analyze the data. RESULTS: After viewing the HWLs, 434 participants (26.9%) reported an intention to quit smoking sooner, 987 (61.2%) reported the same intention to quit, and 191 (11.8%) reported an intention to quit later. The pre-post change in intention to quit was statistically significant among all participants and participants under each theme (p > 0.05). Participants who rated the effectiveness of the HWL communicating how secondhand smoke harms children had 1.13 (95% CI 1.01-1.27) greater odds of reporting an intention to quit sooner compared to those viewing labels from the other themes, adjusting for covariates. Female participants and participants with annual household income more than 100,000RMB had 1.39 (95% CI 1.14-1.69) and 1.29 (95% CI 1.04-1.60) greater odds of reporting an intention to quit sooner compared to their counterparts across the entire sample. CONCLUSIONS: Findings of this study provide evidence of an association between all four pictorial HWL themes and smokers' intention to quit smoking. These findings can help inform what HWL themes might be appropriate when China implements pictorial health warning labels.

Why women continue to smoke during pregnancy: a qualitative study among smoking pregnant women.

Smoking during pregnancy is a serious public health concern due to its adverse consequences on fetal development and pregnant women's health. For the success of smoking cessation interventions, it is essential to determine why pregnant women continue smoking. The objective of this study is to determine the beliefs, attitudes, and barriers to quitting smoking during pregnancy. We adopted a qualitative research design. The participants consisted of 22 pregnant women who smoke, selected by purposive sampling. We collected data through semi-structured interviews and analyzed it using thematic analysis. We identified six themes namely "Reasons for starting to smoke: family and social environment," "Intention to quit smoking and related factors," "Smoking and emotional well-being," "Smoking and stressful life experiences," "Protective thoughts: reducing smoking to safeguard their babies," and "Belief in a healthy pregnancy and inadequate risk perception." Women expressed the desire to protect their fetus from the harm of smoking. However, they continued to smoke due to a lack of knowledge, inadequate risk perception, psychological difficulties, and lack of motivation. Health professionals should be aware of the difficulties experienced by pregnant women who smoke and should support them in quitting smoking.

Oral side effects of locally delivered nicotine replacement therapy: A meta-analysis of randomized controlled trials.

BACKGROUND: Nicotine replacement therapy is the first choice pharmacotherapy for smoking cessation. Oral side effects caused due to NRT lead to discontinuation of treatment. The objective of this meta-analysis was to look for the certainty of evidence on the number of patients that reported oral side effects due to the use of NRT. METHOD: Eligible studies were selected and data extraction was carried out independently into a pre-tested data extraction form. Risk of bias was assessed using Cochrane Tool. The heterogeneity between the studies was assessed using Chi-square and I2 tests. Mean difference and Odds ratio at 95% confidence interval were the effect estimates. GRADE working group approach was used to assess the quality of evidence. RESULTS: Twenty-eight studies were included with moderate to low risk of bias. The pooled estimates revealed a statistically significant number of patients developed mouth or throat irritation (2.54 [1.23, 5.25]), or oral soreness (2.22 [1.40, 3.55]) or gastric reflux or vomiting (1.97 [1.34, 2.90]) due to NRT. CONCLUSION: It is important to understand that significant implications are caused due to NRT, on oral health. All patients on NRT must adhere to their regular dentist visits and must check their oral mucosa before initiating NRT.

An Effective Strategy to Activate Physicians to Promote High Cardiovascular Risk Patients to Quit Smoking.

Background: Adult patients cared for by cardiologists, neurologists, and diabetologists are highly vulnerable to cardiovascular diseases (CVDs), which are worsened by smoking. In the past, physicians of these three specialties at major hospitals in Taiwan always referred patients to family medicine and chest medicine departments for smoking cessation programs. However, the participation rate in these programs was unsatisfactory. Objectives: To encourage cardiologists, neurologists, and diabetologists to provide smoking cessation treatment services (SCTSs) to their patients through an annual contest. Methods: Sequential expert meetings, group training, a contest to reward service quantity and abstinence rate, and an annual awards ceremony were held over the past 3 years. Results: More than 350 cardiologists, neurologists, and diabetologists were certified to provide SCTSs, and in the second half of 2020, 3716 high CVD risk patients entered smoking cessation treatment programs, with an abstinence rate exceeding 30% at 3 months. Conclusions: The strategy used in this study was effective in overcoming physician inertia to provide SCTSs and encourage high CVD risk smokers to quit smoking.

Smoking behaviour among adult patients presenting to health facilities in four provinces of Vietnam.

BACKGROUND: Attendance at healthcare facilities provides an opportunity for smoking cessation interventions. However, the smoking behaviours of patients seeking healthcare in Vietnam are not well-understood. We aimed to evaluate behaviours related to smoking among patients presenting to health facilities in Vietnam. METHODS: We conducted a cross-sectional study in 4 provinces of Vietnam. Consecutive patients aged ≥15 years presenting to 46 health facilities were assessed. Current smokers were randomly selected to complete a full survey about smoking behaviour, quit attempts, and preparedness to quit. RESULTS: Among 11,245 patients who sought healthcare, the prevalence of current smoking was 18.6% (95% CI: 17.8-19.4%) overall, 34.6% (95% CI: 33.2-36.0%) among men and 1.1% (95% CI: 0.8-1.3%) among women. Current smokers who were asked about smoking by healthcare providers in the last 12 months were more likely to make quit attempts than those not asked (40.6% vs 31.8%, p = 0.017). Current smokers who attempted to quit in the past 12 months made limited use of cessation aids: counselling (1.9%) and nicotine replacement therapy (10%). A higher proportion of patients wanted to quit in the next month at national/provincial hospitals (30.3%) than those visiting district hospitals (11.3%, p < 0.001) and commune health centres (11.1%, p = 0.004). CONCLUSIONS: Smoking is common among male patients presenting to healthcare facilities in Vietnam. Formal smoking cessation supports are generally not used or offered. This population is likely to benefit from routine smoking cessation interventions that are integrated within the routine healthcare delivery system.

Nicotine Dependence, Perceived Behavioral Control, Descriptive Quitting Norms, and Intentions to Quit Smoking among Chinese Male Regular Smokers.

BACKGROUND: The association between nicotine dependence and intentions to quit smoking is well established. However, the underlying mechanisms and psychosocial factors that moderate this relationship have not been adequately delineated. Reinforcement theory, social learning theory, the theory of planned behavior, and the focus theory of normative conduct suggest that perceived behavioral control (PBC) over smoking cessation is a central mechanism that underlies the relationship between nicotine dependence and quitting intentions. Purpose/Objectives: The present study tested a moderated mediation model to examine the roles of PBC over smoking cessation and social norms, in the relationship between nicotine dependence and quit intentions among male regular smokers. Methods: Self-report measures of nicotine dependence, PBC over smoking cessation, descriptive and injunctive quitting norms, and intentions to quit smoking were administered to 204 Chinese male regular smokers. Results: Nicotine dependence was negatively related to quit intentions, and this relationship was mediated by PBC over smoking cessation. Further, the relationship between nicotine dependence and PBC was moderated by descriptive rather than injunctive quitting norms. The negative effects of nicotine dependence on PBC over smoking cessation were not significant among male regular smokers who reported strong descriptive quitting norms. Conclusions/Importance: Poor PBC over smoking cessation underlies the negative effects of nicotine dependence, and descriptive quitting norms act as a buffer against the adverse effects of nicotine dependence on PBC over smoking cessation. These findings have implications for smoking cessation interventions for male regular smokers.

Perceived effect of increased pricing on smoked tobacco products quit rates: A cross-sectional study in a block of Haryana.

BACKGROUND: The price of cigarettes and bidis is known to be related to the cessation of these products. OBJECTIVE: To assess the perception of smokers about their quitting behavior on price increase in smoke tobacco product. METHODS: A population-based cross-sectional study among people who were 18 years of age and above was conducted in 2017 among 277 participants in Haryana. Global adult tobacco survey 2009 questionnaire with objective oriented modification was used to examine the willingness to pay (WLP) for a smoked tobacco product, maximum price for quitting smoking, reinitiating smoking, and the knowledge about harmful effects of using tobacco products. Descriptive statistics and odds ratio (OR) with 95% confidence interval (CI) were used to find the relationship among various demographic characteristics and price of quitting smoking. RESULTS: Among the participants, 65 (23.4%) were found to be current smoker and of them 48 (74%) smokers responded to quit smoking on increasing the price of smoked tobacco products. Average daily price paid by the smokers was Rs. 23 and Rs. 8 for cigarettes and bidis, respectively. The odds of quitting smoking among cigarette smokers were higher than those of among bidi smokers (OR = 5.2, 95% CI 2.877-10.04). The odds of quitting smoking among those spending more than Rs. 10/day were lower than those spending 100% increase in current price for quitting smoking. CONCLUSION: An increased magnitude of price increase on smoke tobacco products is invariably an effective method of decreasing smoking prevalence.

[Survey on tobacco sales in newly registered insurance pharmacies and pharmacies in convenience stores in Japan].

Objectives　Pharmacies and pharmacists play an important role in health promotion by supporting citizens' attempts to quit smoking. Nevertheless, some pharmacies sell tobacco themselves. Therefore, we conducted a survey on tobacco sales in pharmacies to investigate regional differences and methods of sale.Methods　As a nationwide survey, we merged the Japanese Local Finance Bureau's 2018 list of enterprisers permitted to sell tobacco with the Japanese Regional Bureau of Health and Welfare's list of insurance pharmacies to calculate the number and proportion of new insurance pharmacies that permit tobacco sales. Additionally, we counted the number and proportion of pharmacies in convenience stores selling tobacco based on the data on their websites and the aforementioned insurance pharmacy list. To provide a survey of existing pharmacies, we confirmed the tobacco selling status, presence of smoking space, presence of anti-passive smoking measures, and the coexistence of drugstores or convenience stores among insurance pharmacies in City A (an urban area in Osaka Prefecture) and City B (a rural area in Ishikawa Prefecture). These data were obtained through site visits from December 2018 to February 2019.Results　Among 1,766 new insurance pharmacies in Japan, 124 (7.0%) were newly permitted to sell tobacco. Many insurance pharmacies in Kanto (71 of 602 new insurance pharmacies; 11.8%) and Tohoku (9 of 110; 8.2%) sold tobacco, while such pharmacies were rare in Shikoku (0 of 64; 0.0%) and Kyushu (1 of 211; 0.5%). Out of the total of 42 pharmacies in convenience stores in Japan, 34 (81%) of them sold tobacco, specifically in urban areas. To provide an existing insurance pharmacy survey, 1 of 28 pharmacies (4%) in City A and 3 of 29 (10%) in City B sold tobacco. All 4 pharmacies sold tobacco at their checkout counters and were located in drugstores. Three of the pharmacies (one in City A and two in City B) had smoking spaces outside, without offering any preventive measure for passive smoking.Conclusion　Many insurance pharmacies sell tobacco in Japan. To encourage pharmacists to support smoking cessation, we need to reach consensus regarding tobacco sales in insurance pharmacies through discussions.

Helping Smokers with Severe Mental Illness Who Do Not Want to Quit.

BACKGROUND: People with a severe and persistent mental illness are far more likely to smoke than others. While a large portion would like to quit, they are less likely to make quit attempts and succeed. OBJECTIVE: This study used an Randomized Controlled Trial (RCT) to test an intervention designed to increase engagement in cessation treatment, quit attempts, and quitting in smokers who did not want to quit in the next 30 days. It also compared these smokers with those who were motivated to quit in the next 30 days. METHODS: Participants (N = 222), were smokers with significant mental illness receiving intensive outpatient care from Wisconsin Community Support Programs who were not interested in quitting in the next 30 days. They were randomly assigned to either an intervention group or an attention control group. The intervention, administered during four weekly sessions, included a motivational element, components designed to prepare the smoker for a quit attempt, and pre-quit nicotine patch. Additionally, 48 smokers motivated to quit in the next 30 days served as a comparison group. RESULTS: Compared to control participants, smokers receiving the intervention were more likely to be abstinent at the three month follow-up (biochemically verified, intent to treat, 8.5% vs. 1.0%, respectively, p = .01). They were also more likely to accept four more quitting preparation sessions (intent to treat, 50.8% vs 29.2%, respectively, p < .001) but were not more likely to call a telephone tobacco quit line. Conclusion/Importance: Brief motivational interventions increased engagement in cessation treatment and abstinence among smokers with signification mental illness.

Assessing Airflow Limitation among Smokers in a Primary Care Setting.

BACKGROUND: Many smokers have undiagnosed chronic obstructive pulmonary disease (COPD), and yet screening for COPD is not recommended. Smokers who know that they have airflow limitation are more likely to quit smoking. This study aims to identify the prevalence and predictors of airflow limitation among smokers in primary care. METHODS: Current smokers ≥ 40 years old who were asymptomatic clinic attendees in a primary care setting were recruited consecutively for two months. We used a two-step strategy. Step 1: participants filled in a questionnaire. Step 2: Assessment of airflow limitation using a pocket spirometer. Multiple logistic regression was utilised to determine the best risk predictors for airflow limitation. RESULTS: Three hundred participants were recruited. Mean age was 58.35 (SD 10.30) years old and mean smoking history was 34.56 pack-years (SD 25.23). One in two smokers were found to have airflow limitation; the predictors were Indian ethnicity, prolonged smoking pack-year history and Lung Function Questionnaire score ≤ 18. Readiness to quit smoking and the awareness of COPD were low. CONCLUSIONS: The high prevalence of airflow limitation and low readiness to quit smoking imply urgency with helping smokers to quit smoking. Identifying airflow limitation as an additional motivator for smoking cessation intervention may be considered. A two-step case-finding method is potentially feasible.

The earlier the better: health-related quality of life is inversely related to age of smoking cessation in older former Italian smokers.

BACKGROUND: Quitting smoking has several health benefits, including an improvement in health-related quality of life. It is not well established if there is a relationship between the age when people stop smoking and health-related quality of life in older adults. AIMS: The primary aim was to investigate the relationship between health-related quality of life and the age when people quit smoking in a national representative sample of community-dwelling older Italian adults. The secondary aim was to describe the characteristics of older former smokers according to their age when they stopped smoking. METHODS: Data were drawn from the "Health and use of health care in Italy", a national cross-sectional survey (2004-2005). Seven thousand five hundred and sixty-two former smokers, aged 65 years and older, were evaluated by age of smoking cessation. Socio-demographic characteristics, physical activity, the 12-Item Short-Form Health Survey (SF-12) score and its physical (PCS-12) and mental (MCS-12) component summary scores, disability and comorbidities were analyzed. RESULTS: Educational level, marital status and area of residence were associated with a different age of smoking cessation, as a higher level of disability and comorbidity. PCS-12 (ß -0.144; p < 0.001) and MCS-12 (ß -0.077; p < 0.001) component scores were lower in subjects who quit smoking later. The relationship was confirmed for the PCS-12 score even after adjustment for socio-demographic, disability and clinical variables (ß -0.031; p < 0.001), while it disappeared for the MCS-12 score (ß -0.010, p = 0.307), after adjustment for comorbidities. CONCLUSION: Physical and mental health-related quality of life is influenced by the age of smoking cessation in older individuals, but this relationship is influenced by comorbidities, particularly depression. Some individual characteristics are related to the age of the person when he/she quit smoking.

Cognitive, behavioural and psychosocial factors associated with successful and maintained quit smoking status among patients who received smoking cessation intervention with nurses' counselling.

AIM: To identify cognitive, behavioural and psychosocial factors associated with successful and maintained quit smoking status after patients received smoking cessation intervention with nurses' counselling. BACKGROUND: Although nurses' intervention for smoking cessation is effective for patients, few studies have been conducted to identify cognitive, behavioural and psychosocial factors associated with the success of quitting smoking. DESIGN: Prospective cohort study METHODS: In a multi-institutional study between October 2008 - October 2014, we administered the Japanese smoking cessation therapy, which consists of smoking cessation intervention five times with nurses' counselling over 12 weeks. Log-binomial regression analysis was performed in 1,320 participants using the following independent variables: age, gender, having a present illness, prescription, Fagerström test for nicotine dependence, strength of desire to quit, age at smoking initiation, previous abstinence, motivation of quit smoking, self-efficacy of quit smoking and Center for Epidemiologic Studies Depression Scale. Factors associated with maintained cessation for 12 months were identified in the 541 abstainers at the end of the intervention. RESULTS: Having higher self-efficacy to quit smoking as assessed before the intervention was significantly associated with the success of quitting smoking at the end of the intervention. Strong desire to smoke as assessed at the end of the intervention was associated with significantly increased risk of discontinuing cessation during the 12 months after the end of the intervention. CONCLUSION: It is important for nurses who provide smoking cessation intervention to reinforce patients' self-efficacy and to control the strength of the patients' desire to smoke by behavioural counselling.

Assessing the impact of a respiratory diagnosis on smoking cessation.

The aim of this study was to assess the impact of respiratory diagnoses on smoking cessation. A total of 229 current and former smokers, with and without respiratory diagnoses completed an anonymous online questionnaire assessing how their smoking habit changed when diagnosed with various respiratory conditions. Among all participants the most common reason for quitting smoking was to reduce the risk of health problems in general. In those with a chronic respiratory diagnosis, this was their most common reason for quitting. Motivation to quit smoking, scored by participants on a scale of 0-10, increased at the time of diagnosis then further increased after diagnosis of a chronic respiratory condition but declined after diagnosis of an acute respiratory condition. The research had a small sample size so further research is required. However, important themes are highlighted with the potential to influence clinical practice. All clinicians should receive training to promote cessation at the time of diagnosing respiratory conditions.

Exploring socio-contextual factors associated with male smoker's intention to quit smoking.

BACKGROUND: Programs to encourage smokers to quit smoking tobacco have been implemented worldwide and are generally viewed as an effective public health intervention program. However, few studies have examined the social factors that influence a smoker's intention to quit smoking. This study investigated the socio-contextual factors that are associated with the intention to quit smoking among male smokers in South Korea. METHODS: Data were obtained from a 2014 nationally representative panel that examined the influences of mass media on the health of the Korean population. Members of this panel were recruited using a mixed-method sampling and a combination of random digit dial and address-based sampling designs. Survey questions were based on those used in previous studies that assessed the effects of social context, including mass media and social capital, on health. Multivariate logistic regression analyses of the answers of 313 male smokers were undertaken. RESULTS: Male smokers who participated in community-based activities were 2.45 times more likely to intend to quit smoking compared to male smokers in general (95 % confidence interval [CI]: 1.25-6.82). In addition, male smokers who participated in informal social gathering networks were 2.38 times more likely to intend to quit smoking compared to male smokers in general (95 % CI: 1.11-5.10). Moreover, male smokers with high smartphone use were 1.93 times more likely than smokers with low smartphone use to intend to quit smoking within one year (95 % CI: 1.07-3.46). CONCLUSIONS: A supportive environment that enables male smokers to access beneficial health information and that encourages them to quit smoking is necessary for a stop-smoking program to be effective. The result of this study contribute to establishing a new smoking control policy by identifying socio-contextual factors related to the intention to quit smoking.

Are electronic nicotine delivery systems an effective smoking cessation tool?

BACKGROUND: Recent studies have estimated that 21% of all deaths over the past decade are due to smoking, making it the leading cause of premature death in Canada. To date, many steps have been taken to eradicate the global epidemic of tobacco smoking. Most recently, electronic nicotine delivery systems (ENDS) have become a popular smoking cessation tool. ENDS do not burn or use tobacco leaves, but instead vapourize a solution the user then inhales. The main constituents of the solution, in addition to nicotine when nicotine is present, are propylene glycol, with or without glycerol and flavouring agents. Currently, ENDS are not regulated, and have become a controversial topic. OBJECTIVES: To determine whether ENDS are an effective smoking cessation tool. METHODS: A systematic literature search was conducted in February 2015 using the following databases: PubMed, Scopus and Web of Science Core Collection. Randomized controlled trials were the only publications included in the search. A secondary search was conducted by reviewing the references of relevant publications. RESULTS: After conducting the primary and secondary search, 109 publications were identified. After applying all inclusion and exclusion criteria through abstract and full-text review, four publications were included in the present literature review. A low risk of bias was established for each included study using the Cochrane Collaboration risk of bias evaluation framework. DISCUSSION: The primary outcome measured in all studies was self-reported abstinence or reduction from smoking. In three of the four studies, self-reported abstinence or reduction from smoking was verified by measuring exhaled carbon monoxide. In the remaining study, the primary outcome measured was self-reported desire to smoke and measured desire to smoke. All four studies showed promise that ENDS are an effective smoking cessation tool. CONCLUSIONS: While all publications included in the present review revealed that ENDS are effective smoking cessation aid, further evaluation of the potential health effects in long-term use of ENDS remains vital.

HISTORIQUE: Selon les études récentes, 21 % de tous les décès depuis dix ans sont attribuables au tabagisme, ce qui en fait la principale cause de décès prématurés au Canada. Jusqu'à présent, de nombreuses mesures ont été prises pour éradiquer l'épidémie mondiale de tabagisme. Récemment, les systèmes électroniques de délivrance de nicotine (SÉDN) sont devenus un outil populaire d'abandon du tabac. Les SÉDN ne brûlent ni n'utilisent de feuilles de tabac, mais vaporisent une solution que le consommateur inhale. Les principaux éléments de la solution, en plus de la nicotine lorsque le système en contient, sont le propylèneglycol, accompagné ou non de glycérol et de substances aromatisantes. Les SÉDN ne sont pas réglementés, mais sont devenus controversés. OBJECTIFS: Déterminer si les SÉDN sont un outil efficace d'abandon du tabac. MÉTHODOLOGIE: Les chercheurs ont effectué une analyse bibliographique systématique en février 2015 à l'aide des bases de données suivantes : PubMed, Scopus et Web of Science Core Collection. Ils ont inclus seulement les essais aléatoires et contrôlés dans leur recherche. Dans une recherche secondaire, ils ont analysé les références des publications pertinentes. RÉSULTATS: Après avoir terminé les recherches primaire et secondaire, les chercheurs ont extrait 109 publications. Après avoir appliqué tous les critères d'inclusion et d'exclusion à l'analyse des résumés et des textes intégraux, ils ont intégré quatre publications à la présente analyse bibliographique. À l'aide du cadre d'évaluation du risque de biais de la Collaboration Cochrane, ils ont établi que chaque étude s'associait à un faible risque de biais. EXPOSÉ: Le résultat clinique primaire mesuré dans les études était une abstinence ou une réduction autodéclarée du tabagisme. Dans trois des quatre études, l'abstinence ou la réduction autodéclarée du tabagisme était mesurée par le monoxyde de carbone expiré. Dans la dernière étude, le résultat clinique primaire était le désir autodéclaré de fumer et le désir mesuré de fumer. Les quatre études ont révélé que les SÉDN sont un outil efficace d'abandon du tabac. CONCLUSIONS: Toutes les publications incluses dans la présente analyse ont révélé que les SÉDN sont des outils d'abandon du tabac, mais il demeure essentiel d'en évaluer davantage les effets potentiels à long terme sur la santé.

Preliminary Survey Data From an App-Delivered Hypnosis Intervention for Smoking Cessation.

Introduction: Hypnosis-based apps geared toward smoking cessation are among the most downloaded by individuals wanting to reduce or stop smoking. However, to date, there are few evaluations regarding the use or efficacy of hypnosis apps for smoking cessation. Finito is an empirically-based mHealth app developed by Mindset Health designed to provide users with a three-week hypnotherapy program to quit smoking. This study aimed to examine demographic and clinical characteristics of Finito app users and conduct a preliminary analysis of survey data from participants of the program. Method: Finito app users were asked to voluntarily complete an online survey regarding their experience with the program, current smoking habits, app usability, relevant improvement, and demographic information. Retrospective data analyses were conducted to provide descriptive and inferential findings from the responses. Results: A total of 120 individuals responded to the survey. Respondents originated from over five different countries and approximately 72.5% reported completing the full Finito program. Approximately 58.3% of participants reported that they accomplished their goal with Finito with 50.8% of all respondents reporting that they quit smoking and an additional 25.8% reporting that their smoking was reduced. Among a variety of secondary outcomes, saving money was the most frequently reported secondary benefit with 46.7% of respondents endorsing that item. Conclusion: Our preliminary survey results suggest that Finito may be a useful, pleasant, and cost-effective tool in a patient's journey to quit smoking. The majority of app users reported that they achieved their goal with Finito and completion of the program was associated with goal achievement. The Finito app may be effective in the dissemination and delivery of a helpful hypnotherapy intervention across a diverse population.

Prevalence of smoking habits, attitudes and knowledge on counteractive strategies among a sample of healthcare employees: results of the smoking-free health environments project in the province of Palermo, Italy.

Introduction: Tobacco use is responsible for over 7 million deaths annually, making smoking the leading cause of preventable mortality globally. Over the last two decades in Italy, the prevalence of smoking among physicians has consistently decreased, while it remains higher and is gradually decreasing among non-physician healthcare workers. The aim of this study was to investigate the Prevalence of smoking habits, attitudes, and knowledge on counteractive strategies among employees in the Primary Healthcare Facilities in the Province of Palermo, Italy. Methods: A cross-sectional survey was conducted between June 2020 and December 2020 through a previously validated anonymous questionnaire structured in four sections including 34 items. Data were analyzed using Stata/MP 12.1 statistical software. Results: Overall, 2,645 participants answered the questionnaire. The prevalence of either current or former smokers was 18.6%. Based on the multivariable analysis conducted, a significantly higher frequency of current smokers was observed among male participants (AdjOR: 1.29; CI95%: 1.02-1.64) and those belonging to the Surgical Unit (AdjOR: 1.92; CI95%: 1.27-2.90). Conversely, the prevalence of current smokers was significantly lower among those with at least one child (AdjOR: 0.67; CI95%: 0.49-0.91), with an educational qualification equal to or greater than a graduation degree (AdjOR: 0.56; CI95%: 0.43-0.73), those who considered second-hand smoke harmful (AdjOR: 0.06; CI95%: 0.008-0.60), those who had observed smoking or detected the smell of smoke in their workplace (AdjOR: 0.64; CI95%: 0.45-0.91). Furthermore, the prevalence of current smokers was significantly lower among participants who believed that healthcare professionals could play a crucial role in influencing their patients' lifestyles (AdjOR: 0.67; CI95%: 0.50-0.90) and among those who recommend their patients to quit smoking (AdjOR: 0.35; CI95%: 0.24-0.51). Discussion: The results of the current research demonstrate that, despite the decline in smoking prevalence among physicians, the rate of smokers among healthcare facility employees remains unacceptably high. This underscores the need to re-evaluate current anti-tobacco strategies in the workplace.
