Association of conventional and electronic cigarette use with suicidality in Chinese adolescents: The moderating effect of sex and school type

BackgroundTo estimate the prevalence of lifetime e-cigarette use and explore the association between lifetime conventional and electronic cigarette use with suicidality among Chinese adolescents, focusing on sex and school-type differences. MethodsA total of 22,509 students from 432 classes in 80 schools were recruited in Guangdong Province using a multistage, stratified cluster, random sampling method in 2021. Self-report questionnaires were used to collect information. Multivariable logistic regression models were performed and stratification analysis was conducted. All analyses were weighted and adjusted for the complex survey design. ResultsThe weighted prevalence of lifetime e-cigarette use among adolescents in Guangdong Province was 8.7 % (4.3 % were dual users and 4.4 % were e-cigarette-only users) and 2.6 % were conventional-cigarette-only users. Lifetime e-cigarette-only users (AOR [Adjusted OR] =1.46, 95 % CI = 1.21–1.76), conventional-cigarette-only users (AOR = 1.97, 95 % CI = 1.58–2.46) and dual users (AOR = 1.67, 95 % CI = 1.38–2.02) were at a higher risk of suicidal ideation than non-users. Lifetime e-cigarette-only users (AOR = 2.03, 95 % CI = 1.53–2.70), conventional-cigarette-only users (AOR = 1.97, 95 % CI = 1.42–2.73), and dual users (AOR = 2.76, 95 % CI = 2.10–3.61) had a significantly higher risk of suicide attempts than non-users. After further analysis stratified by sex and school type, the associations of lifetime cigarette use patterns with suicidality slightly varied. LimitationThe cross-sectional study design and self-report information. ConclusionThe prevalence of e-cigarettes among Chinese adolescents is concerning. Lifetime conventional and e-cigarette use were associated with suicidality among Chinese adolescents, with sex and school type moderating these associations. Targeted measures to restrict cigarette use, including new tobacco product (e-cigarette) use, among adolescents are warranted.

Social Epidemiology of Early Initiation of Electronic and Conventional Cigarette Use in Early to Middle Adolescents.

Early initiation of tobacco use among adolescents is a significant public health concern. While there is extensive research on overall tobacco use, much of it focuses on initiation in late adolescence, uses cross-sectional designs, and lacks specific exploration of electronic versus conventional cigarette use. This study aims to investigate social determinants influencing the early initiation of electronic and conventional cigarette use among U.S. adolescents. We utilized data from the Adolescent Brain Cognitive Development (ABCD) study, which follows a cohort of tobacco-naïve children from age nine through age 16. The social determinants examined included household income, parental education, financial difficulties, racial/ethnic minority status, family structure, neighborhood income, and gender minority status. Structural equation models were employed to assess associations between these determinants and early initiation of electronic and conventional cigarette use. Male gender was associated with a higher likelihood of conventional cigarette use, while the risk of early initiation of electronic cigarette use was similar across genders. White adolescents were at a higher risk of conventional cigarette use; however, the risk for electronic cigarette use was comparable across White and non-White groups. Financial difficulties were linked to an increased likelihood of early initiation of conventional cigarette use but not electronic cigarette use. Higher household income was associated with a reduced risk of initiating conventional cigarettes but did not significantly impact electronic cigarette use. Adolescents from married families were less likely to initiate electronic cigarette use. No significant effects were found for parental education or neighborhood income on the initiation of either type of cigarette use. Age did not significantly affect the initiation of either cigarette type, and gender minority status was marginally associated with early initiation of conventional cigarette use. The social patterning of electronic cigarette use differs from that of conventional cigarette use, suggesting that distinct tobacco products do not pose a uniform risk across all adolescents. This study underscores the importance of tailored prevention efforts that address the unique challenges associated with early initiation of electronic and conventional cigarette use among adolescents. The differential risk factors identified suggest targeted prevention strategies for conventional cigarette use, focusing on financial difficulties, household income, and gender-specific interventions. In contrast, prevention efforts for electronic cigarette use may require broader, more inclusive approaches that address all adolescents, regardless of their background. Comprehensive universal screening for electronic cigarette use and targeted screening for conventional cigarette use among adolescents are recommended.

Micronuclei in buccal mucosa cells of smoking university students: a genotoxicity study

This study explores and contrasts the genotoxic effects of conventional and electronic cigarette use on the buccal mucosa cells of university students, using the micronucleus test. We conducted field research with qualitative and quantitative methods, involving 28 participants over 18 years old, distributed into four groups: conventional cigarette users, electronic cigarette users, dual users, and non-smokers. Participants were selected based on specific criteria, and demographic and motivational information was obtained through questionnaires. Buccal mucosa samples were collected according to standard cytological methods, analyzing 500 cells per participant. Analysis revealed statistically significant differences in micronucleus incidence and cellular alterations between smoker and non-smoker groups. These findings underscore the need for stricter tobacco control policies and pave the way for future research on tobacco genotoxicity.

Polygenic and socioeconomic contributions to nicotine use and cardiometabolic health in early mid-life.

Early mid-life is marked by accumulating risks for cardiometabolic illness linked to health-risk behaviors like nicotine use. Identifying polygenic indices (PGI) has enriched scientific understanding of the cumulative genetic contributions to behavioral and cardiometabolic health, though few studies have assessed these associations alongside socioeconomic (SES) and lifestyle factors. Drawing on data from 2,337 individuals from the United States participating in the National Longitudinal Study of Adolescent to Adult Health, the current study assesses the fraction of variance in five related outcomes - use of conventional and electronic cigarettes, body mass index (BMI), waist circumference, and glycosylated hemoglobin (A1c) - explained by PGI, SES, and lifestyle. Regression models on African ancestry (AA) and European ancestry (EA) subsamples reveal that the fraction of variance explained by PGI ranges across outcomes. While adjusting for sex and age, PGI explained 3.5%, 2.2%, and 0% in the AA subsample of variability in BMI, waist circumference, and A1c, respectively (in the EA subsample these figures were 7.7%, 9.4%, and 1.3%). The proportion of variance explained by PGI in nicotine-use outcomes is also variable. Results further indicate that PGI and SES are generally complementary, accounting for more variance in the outcomes when modeled together versus separately. PGI are gaining attention in population health surveillance, but polygenic variability might not align clearly with health differences in populations or surpass SES as a fundamental cause of health disparities. We discuss future steps in integrating PGI and SES to refine population health prediction rules. Study findings point to the complementary relationship of polygenic indices (PGI) and socioeconomic indicators in explaining population variance in nicotine outcomes and cardiometabolic wellness. Population health surveillance and prediction rules would benefit from the combination of information from both polygenic and socioeconomic risks. Additionally, the risk for electronic cigarette use among users of conventional cigarettes may have a genetic component tied to the cumulative genetic propensity for heavy smoking. Further research on PGI for vaping is needed.

Association between e-cigarette and conventional cigarette use among Spanish adolescents.

In recent years, studies have highlighted the upward trend in electronic cigarette use among adolescents, as well as the potential of e-cigarette use to lead to subsequent conventional cigarette use. The study's aims were two-fold: 1) to examine the progression from e-cigarette use to conventional cigarette use; and 2) to analyze the differences in the severity of smoking pattern among dual users (i.e., e-cigarette and conventional cigarette use), cigarette-only smokers, and e-cigarette-only users in a Spanish adolescent population. Data were obtained from the ESTUDES, a representative survey of addictive behaviors of Spanish adolescents aged 14-18, which was comprised of 38,010 adolescents (Mage = 15.69; SD = 1.19; 51.35% females). Results indicate that lifetime e-cigarette use increased the prevalence of subsequent conventional cigarette use by 1.86 times (95% CI 1.74, 1.99), and the prevalence of conventional cigarette use in the last month by 2.38 times (95% CI 2.19, 2.58), independently of whether the e-cigarette contains nicotine or not. Dual users showed a higher percentage of daily smokers, and a greater number of cigarettes per day, a higher use of e-cigarettes with nicotine, and an earlier age of smoking onset. Regarding risk perception, e-cigarette-only users perceived both conventional tobacco and e-cigarettes as less harmful (all p-values < .001). These findings document the strength of association between e-cigarette and conventional cigarettes, and underscore the importance of developing legal restrictions and prevention strategies aimed at reducing e-cigarette use, which in turn would reduce tobacco use.

Does sensation-seeking behavior influence the patterns of flavored e-cigarette use? A cross-sectional study among Indonesian adolescents and young adults

BackgroundThe variety of available flavors in e-cigarettes may be a driver for young people to start using these products. The objectives of our study were to examine the relationship between sensation-seeking behavior and e-cigarette use, and to identify the predictors of flavor use patterns among adolescents in Indonesia.MethodsStudents aged 15 to 24 years participated from randomly selected high schools and universities in Indonesia. Participants answered questions about their demographic data, e-cigarette use, conventional cigarette use, and sensation-seeking. Flavor preferences were identified from eight different flavor categories. Multivariate multinomial regression analysis was employed to predict conventional cigarette and e-cigarette use among students. A latent class analysis was conducted to determine the number of latent classes of flavor use.ResultsOne thousand six hundred high school and university students, with a mean age of 18.2 years (SD 2.19), were recruited between March and August, 2023. Conventional cigarette use in the past 30 days was higher (16.3%) compared to e-cigarette use (13.3%, p = 0.017), with approximately 8.5% of students were being dual users. Higher levels of sensation-seeking significantly increased the odds of being a current e-cigarette user (OR = 2.54, 95%CI 1.99–3.25) and a current conventional cigarette smoker (OR = 2.38, 95%CI 1.85–3.07). Three groups of flavor classes were identified: 1) primarily menthol flavor users (14%), who had a strong association with current conventional cigarette use; 2) experimenters, who mostly preferred fruit-flavored e-cigarettes (76%); and 3) the multi-flavor user group (10%), who had a higher sensation-seeking tendency.ConclusionsFlavors, especially menthol and fruit flavors, attract youth, broaden the e-cigarette audience and are particularly appealing to high sensation-seekers. Banning these flavors could significantly deter e-cigarette initiation among youth.

A comparison of the caries risk between patients who use vapes or e-cigarettes and those who use conventional cigarettes: a cross-sectional study

Aims: Both conventional cigarette use and e-cigarette/vape use appear to have detrimental effects on oral health by promoting the development of both dental caries and periodontal disease. This study aimed to compare the effects of the two with regards to dental caries risk level. Methods: A cross-sectional study on patient records was conducted. 1251 patients who attended the dental school clinics and met the inclusion criteria were included. The Kruskal-Wallis test and multivariable ordinal logistic regression were used to compare the e-cigarette/vaping only, conventional cigarette use only, and dual e-cigarette/vaping and conventional cigarette use groups in terms of caries risk. Results: A total of 1251 patient records met the inclusion criteria. There were 130 reported active users of e-cigarettes/vapes, 1094 active users of conventional cigarettes and 27 active users of both e-cigarettes/vapes and conventional cigarettes. The Kruskal-Wallis test showed no statistically significant difference between caries risk level among the 3 groups with 88.9% of the dual smokers (both conventional and e-cigarettes/vapes), 83.1% of the e-cigarette/vape only users, and 82.5% of the conventional cigarette only smokers being placed in the high/extreme caries risk category (P=.693). The comparison was also not significant (P=.719) when adjusting for age and gender. Conclusion: Though the percentage of patients in the high/extreme caries risk category was highest in the dual smokers group, followed by the vaping/e-cigarette use group and lastly the conventional cigarette group, there was no statistically significant evidence of a difference between these groups.

The Rising Use of E-Cigarettes: Unveiling the Health Risks and Controversies.

The use of e-cigarettes has tremendously increased in recent times due to the widespread availability of e-cigarettes in diverse flavors, reduced cost compared to regular cigarettes, and misconception of being comparatively safe, which have led to around 2.55 million US middle and high school students smoking e-cigarettes. These devices use a nicotine-rich liquid, which is aerosolized electronically, producing vapors that may also include hazardous chemicals and heavy metals. E-cigarettes are associated with e-cigarette or vaping-associated lung injury, which presents as an acute respiratory ailment mirroring various pulmonary diseases. Additionally, it causes endothelial dysfunction, alters blood lipid profile by elevating circulating levels of low-density lipoprotein cholesterol, increases sympathetic tone, and is found to correlate with arterial stiffening, hence negatively affecting respiratory, cardiovascular, and overall health. We aim to provide a comprehensive analysis of the data on e-cigarettes and their harmful effects on health in comparison to conventional cigarette use by highlighting the pathophysiology of e-cigarette-induced adverse effects and critically analyzing the data both in favor and against its use. Our review concludes that no matter how much nicotine an e-cigarette contains, evidence shows that using it increases the risk of cardiovascular disease, albeit maybe not as much as smoking regular tobacco. Nonetheless, it is crucial to note that the long-term effects of e-cigarette usage are still not fully understood, and existing data have provided opposing viewpoints.

School climate and school identification as determinants of smoking conventional cigarettes or vaping among adolescents in China: Stress-coping mediation mechanisms.

Smoking conventional cigarettes or vaping (SV) poses significant health threats to adolescents. School climate and school identification are key elements of the school environment and potential factors of SV. Based on the Stress Coping Theory, the mediations between school climate/school identification and SV, via perceived stress/active coping, were examined. A cross-sectional survey was conducted among secondary school students from February to March 2022 in Taizhou, China. Structural equation modeling was used. The prevalence of SV among the 7526 participants was 4.7% (singular use of conventional cigarettes: 3.2%; singular use of electronic cigarettes: 3.6%; dual use: 2.1%). School climate, school identification, and active coping were positively, and perceived stress (family stress, academic stress, and peer-related stress) were negatively associated with SV. The association between school climate and SV was fully mediated via: 1) school climate → perceived stress → SV; 2) school climate → active coping → SV; and 3) school climate → perceived stress → active coping → SV. The effect sizes were 52.1%, 43.8%, and 6.3%, respectively. Similar partial mediation mechanisms were found between school identification and SV, with relatively small effect sizes (<10%). This study observed the prevalence of SV among Chinese secondary school students. School climate and school identification had both significant direct and indirect (via perceived stress/active coping) effects on SV. Positive school environments may reduce students' stress and promote active coping. The stress coping mechanisms explained the association between school climate and SV better than between school identification and SV.

Impact of electronic cigarette use on the increased risk of diabetes: the Korean Community Health Survey.

Only a few studies have solely investigated the health impacts of electronic cigarettes on diabetes while considering the impact of conventional cigarettes. Therefore, this study aimed to examine the effect of electronic cigarette smoking on diabetes in Korean dual smokers, electronic cigarette smokers, conventional cigarette smokers, and non-smokers. Data were obtained from the 2021 and 2022 Korean Community Health Surveys of 460,603 Korean adults. The main independent variable was smoking behavior. Participants were categorized according to their smoking behavior, as dual smokers, electronic cigarette smokers, conventional cigarette smokers, and non-smokers. The dependent variable, the presence of diabetes, was defined by a doctor's diagnosis. Multiple logistic regression analysis was performed to examine the association between smoking behavior and diabetes. Subgroup analyses were also performed to investigate the associations among different socioeconomic groups. Conventional cigarette smokers had a higher risk of diabetes than did non-smokers (adjusted odds ratio [aOR], 1.22; 95% confidence interval [CI], 1.19 to 1.26). More importantly, those who only vaped electronic cigarettes were at high risk of diabetes (aOR, 1.15; 95% CI, 1.01 to 1.31). Lastly, dual smokers had the highest aOR for diabetes among other smoking behavior groups (aOR, 1.39; 95% CI, 1.22 to 1.58). Dual smoking was associated with the highest risk of diabetes in most subgroups. This study suggests that conventional cigarette use and smoking electronic cigarettes negatively impact diabetes, and using both types leads to worse health outcomes. Therefore, cessation of all types of smoking is necessary for a healthy life.

The association between health literacy and e-cigarette use: evidence from Zhejiang, China.

The worldwide popularity of electronic cigarettes (ECIG) is becoming a public health concern. Compared to conventional cigarettes (CIG), the harm caused by ECIG is more insidious. Studies have shown that lower health literacy (HL) is associated with CIG use; however, the relationship between HL and ECIG use remains controversial. Because ECIG emerged more recently than CIG, there are fewer relevant studies, and the sample populations and evaluation methods of HL in existing studies differ. This study conducted a large-sample survey to examine the relationship between HL and ECIG use. As part of the 2022 China Health Literacy Survey, a total of 60,998 valid questionnaires were collected from September to November in 2022 using a stratified multistage probability proportional to the population size sampling frame. Chi-square tests and multinomial logistic regression was used to analyze the relationship between HL and ECIG use. Some demographic variables were included as covariates in the analysis. The study showed that the average HL score and the HL level of Zhejiang residents in 2022 were 42.8 and 30.8%, respectively. The prevalence of CIG and ECIG was 19.7 and 1.0%, respectively; 19% of participants exclusively used CIG, while only 0.3% of participants used ECIG exclusively; dual users accounted for 0.6%. After adjusting for covariates, adequate HL was associated with lower odds of ECIG-exclusive use (odds ratio [OR] = 0.452, p < 0.001), CIG-exclusive use (OR = 0.833, p < 0.001), and dual use (OR = 0.632, p < 0.001). Young age, male sex, unmarried status, high-income status, and absence of chronic disease were also associated with ECIG use. HL was a protective factor against both patterns of ECIG use, especially ECIG-exclusive use. Health policymakers and public health practitioners should consider HL as a potential measure for ECIG control.

The Use of Vaping Among Male Health Sciences Students Compared to Other Male Students in Riyadh.

Background Vaping has become widely used by teenagers due to its accessibility, variety of flavors, peer influence, and the thought that it is a less harmful alternative to tobacco smoking. This study aimed to compare the prevalence of vaping among health sciences students compared to other college students in Riyadh and identify reasons for its usage. Methods A cross-sectional study was conducted in three major universities of Riyadh: King Saud bin Abdulaziz University, King Saud bin Abdulaziz University for Health Sciences, and Al-Imam Mohammad Ibn Saud Islamic University. A self-administered online questionnaire related to the use of e-cigarettes and conventional cigarettes was utilized. It included questions about the use of conventional cigarettes and e-cigarettes and the reasons for using them. Responses were compared between health sciences and non-health sciences students in Riyadh. Results An electronic survey was distributed online, and 442 students responded, but two of them did not agree to participate, so they were removed from the sample. Out of 440 students, 312 (71%) were health sciences students, and 128 (29%) were non-health sciences students. Smoking conventional cigarettes was found among 38 (12%) health sciences students, and 22 (17%) non-health college students smoked conventional cigarettes (p=0.16). Regarding vaping, 117 (38%) health sciences students smoked e-cigarettes. On the other hand, 47 (39%) non-health college students smoked e-cigarettes (p=0.99). Anxiety/stress relief (54%) and peer influence (46%) were the most common reasons for those who smoked conventional cigarettes. Regarding the most common reasons behind using e-cigarettes, the majority (55%) considered e-cigarettes less harmful than conventional cigarettes. The second most common reason was having no distinctive odor (36%). Conclusion The study found that there was a high prevalence of the self-reported use of e-cigarettes. It appears that the use of conventional cigarette smoking is not as common as e-cigarettes among university students. This study found that university students tend to use e-cigarettes more than conventional cigarettes due to the belief thate-cigarettes are less harmful than conventional cigarettes.

Comparison of the responses of cross-sectional web- and paper-based surveys on lifestyle behaviors of Japanese adolescents

ObjectiveIn Japan, paper-based surveys are currently more effective than web-based surveys. This study compared the response rates and lifestyle behaviors between paper- and web-based surveys conducted among Japanese junior and senior high schools. MethodsIn total, there were 42 and 64 junior and senior high schools, respectively, for the web-based surveys and 20 and 27 junior and senior high schools, respectively, for the paper-based surveys. The questionnaire covered lifestyle behaviors (e.g., alcohol consumption, smoking, exercise, eating, and sleep status), mental health, and plans to attend college. School- and student-level response rates by survey method were assessed, and so was the effect on the reporting of each lifestyle behavior using logistic regression models. ResultsThe school response rates were 16.0% and 38.3% for web- and paper-based surveys, respectively. The student response rates were 88.7% and 77.2%, respectively. The web-based group had significantly more female participants and lower response rates for higher grades in senior high schools. The odds of lifetime and current alcohol consumption and poor mental health were lower, whereas those of lifetime use of conventional cigarettes, shorter sleep duration, and plans to continue attending college were higher among web-based (vs. paper-based) participants. ConclusionsThe school response rate was poor in the web-based survey. However, whether the differences in lifestyle behavior are attributed to selection bias or the survey method remains unclear.

Association of dual use of cigarettes with obstructive sleep apnea assessed by the STOP-Bang score.

Although previous studies have addressed the association between smoking and obstructive sleep apnea (OSA), there are few studies on the association between electronic cigarette use and OSA. Thus, we aimed to evaluate the association between the dual use of electronic and conventional cigarettes and OSA. Data from 7350 participants of the 2019-2021 Korean National Health and Nutrition Examination Survey were analyzed in this population-based study. The STOP-Bang score was calculated using eight items: snoring, tiredness, observed apnea, high blood pressure, body mass index, age, neck circumference, and sex. The main independent variable was smoking behavior. A multiple logistic regression analysis was performed. Subgroup analysis was conducted to analyze the association between smoking behavior in detail and OSA, and stratified analyses were additionally performed. Of the 7350 participants, 417 (5.7%) had a high risk of OSA, according to the STOP-Bang score. Compared to the non-smoker group, the dual user group had a 2.46-fold increase in the odds of OSA (adjusted odds ratio, AOR = 2.45; 95% CI: 1.04-5.79). Current non-smokers who were dual users in the past had increased odds of having OSA (AOR=3.61; 95% CI: 1.32-9.92). In the stratified analyses, dual cigarette use was significantly associated with OSA in females and those with a low physical activity level. Dual users and cigarette-only users had an increased probability of developing OSA. Even if they are not currently smoking or vaping, individuals who were dual users in the past were associated with a higher risk of OSA. The association between dual cigarette use and OSA was more pronounced in females and those with a low physical activity level. While intervening for obstructive sleep apnea or investigating risk factors, new smoking methods such as vaping and dual use should be considered along with conventional smoking.

E-Cigarette, Conventional Cigarette, and Depression: Role of Race/Ethnicity in the Health Information National Trends Survey (HINTS) 2022

Background: While previous research has established the role of depression as a correlate of tobacco use, limited research has been conducted on potential racial variations in these associations. Aims: This study had two objectives: (1) to investigate the associations between depression and smoking conventional and vaping e-cigarettes, and (2) to explore the role of race in modifying these associations. Methods: Data from the Health Information National Trends Survey (HINTS-2022) survey, which is a national probability sample of US adults, were analyzed. Variables of interest included lifetime and current smoking status, e-cigarette use, depression (PHQ-4), socioeconomic status (SES), and demographic characteristics. Binary logistic regression models were applied to assess the associations between depression as the independent variable and current and ever smoking conventional cigarettes and vaping e-cigarettes as dependent variables, adjusting for covariates (age, gender, education, marital status, and employment). We tested potential interactions between race/ethnicity (non-Hispanic Whites, non-Hispanic Blacks, Hispanic Whites and any other/mixed race/ethnicity) and depression on our outcomes. Results: The study findings indicated significant associations between depression and use of conventional cigarettes and e-cigarettes. Although individuals who were experiencing depression were more likely to use conventional cigarettes (p &lt; 0.05) and e-cigarettes (p &lt; 0.05) compared to those non-depressed, the positive associations between depression and lifetime and current smoking were stronger for Black than White individuals. Conclusions: This study suggests that depression may have a more salient role in smoking cigarettes and e-cigarette use for Black than White adults. It is unclear if Black adults are more likely to smoke if they are depressed, or if Black adults who smoke cigarettes are more likely to be depressed because of higher stigma and lower access to mental health care services.

Factors associated with smoking cessation in exclusive smokers and dual users of e-cigarette and conventional cigarettes from CDTnet registry

Dual use of electronic cigarettes and conventional cigarettes may be a transitional state towards cigarette smoking cessation. However, maintaining dual use may increase tobacco-related consequences as smoking behavior persists. The aim of our study was to describe characteristics of dual users and explore factors associated with their one-month abstinence in comparison to exclusive smokers in French smoking cessation services (SCS). We retrospectively studied 5116 smokers registered in a national SCS registry between 2015 and 2018 and who attended at least two visits. We matched the retained exclusive smokers and dual users by age, sex, professional status and education level. We compared baseline information and validated smoking abstinence at one-month follow-up between the two groups. Predictors of abstinence were assessed using a multivariate model. Retained exclusive smokers and dual users had similar cessation rates (37%). Compared to exclusive smokers, dual users presented more comorbidities and a higher level of nicotine dependence. Factors positively associated with cessation in dual users were: being employed or retired, declaring three or more previous quit attempts, presenting with low nicotine dependence and high motivation to quit and benefiting from at least four follow-up consultations. Our results suggest that dual users seeking help to quit in SCS seem to benefit from support as much as exclusive smokers to reach abstinence, despite a higher level of nicotine dependence and comorbidities. Further research, especially qualitative, is needed on this specific group of smokers to provide tailored interventions to quit.

Association between exposure to different sources of advertising and the use of conventional cigarettes in Peruvian adolescents, 2019.

The objective of this study was to evaluate the association between exposure to different sources of tobacco advertising and the consumption of conventional cigarettes in Peruvian adolescents. This was a cross-sectional analytical study of secondary data from the Global Youth Tobacco Survey (GYTS) 2019 in Peru. The population consisted of adolescents aged 13-15 years. Generalized Linear Poisson family models were used to estimate prevalence ratios with their 95% confidence intervals (95% CI), which measured the strength of the association between exposure to advertising sources and conventional cigarette consumption. Data from 2083 adolescents who provided information on exposure to television advertising, 1092 on outdoor advertising, and 2008 about online advertising were analyzed. A higher probability of conventional cigarette consumption was noted in those exposed to ads via television (aPR=1.85; 95% CI: 1.28-2.69; p=0.002) and online (aPR=1.90; 95% CI: 1.40-2.58; p<0.001), in comparison with those not exposed. Tobacco advertising, promotion and sponsorship (TAPS) through television and online media are significantly associated with an increase in the consumption of conventional cigarettes among adolescents aged 13-15 years. Therefore, it is necessary to implement comprehensive bans on TAPS in Peru focused on these media to prevent the tobacco industry from continuing to introduce advertising to encourage tobacco consumption.

A cross-sectional study on the relationship between electronic cigarette and combustible cigarette use with obstructive sleep apnea among U.S. adults: result from NHANES 2015–2018

BackgroundTo explore whether the use of e-cigarettes and conventional cigarettes affects the prevalence of obstructive sleep apnea (OSA) in adults.MethodsComplete records of smoking and sleep about OSA from the 2015–2018 National Health and Nutrition Examination Survey. The adults were divided into four groups: noncurrent smokers, current electronic cigarettes (e-cigarette) users only, current conventional cigarettes (c-cigarette) users only, and dual users. OSA was assessed by three main signs and symptoms from the questionnaire. Multivariable logistic regression after adjusting for covariates was conducted to investigate the association of OSA with different smoking patterns.ResultsAmong the 11,248 participants, the prevalence of OSA was higher among smokers compared to non-smokers (P < 0.0001). In a stratified analysis of smoke manners, the results showed that an increased prevalence of OSA with c-cigarette use alone (OR = 1.38, 95% CI = 1.17–1.63) and dual-use (OR = 1.78, 95% CI = 1.37–2.32) compared to non-smoking participants, while there was no significant difference with e-cigarette use (OR = 0.84, 95% CI = 0.52–1.37). Multivariate logistic regression analysis showed the prevalence of OSA is highest in dual users (OR = 1.93, 95% CI = 1.39–2.69) than non-smokers.ConclusionOur findings indicate the prevalence of OSA was higher in c-cigarette smokers than in non-smokers, while there was no significant difference in the prevalence of OSA between e-cigarette smokers and non-smokers. Dual users had the highest prevalence for OSA compared to c-cigarette smokers, e-cigarette smokers and non-smokers.

Heated Tobacco Products and Chronic Obstructive Pulmonary Disease: A Narrative Review of Peer-Reviewed Publications

An estimated 65 million people worldwide have moderate or severe chronic obstructive pulmonary disease (COPD), an umbrella term used to describe a group of progressive lung diseases that obstruct airflow such as emphysema and chronic bronchitis. Smoking contributes to an estimated 90% of COPD cases, as the harmful chemicals produced during tobacco combustion damage the lungs and airways. Although smoking cessation is the only intervention shown to improve COPD prognosis in smokers, many patients who try to quit continue to smoke. The continued use of conventional cigarettes exacerbates COPD symptoms, and globally more than 3 million people die from the disease every year. The last two decades have seen the introduction of combustion-free nicotine delivery alternatives that produce significantly lower levels of the harmful components in cigarette smoke, and researchers have begun to assess the impact of switching from cigarettes to these products. Several studies have examined how patients with COPD use e-cigarettes as assistance for quitting, but few have examined how heated tobacco products (HTP) may reduce risk. This narrative review summarises results from pre-clinical, clinical, and real-world evidence studies showing possible harm reduction benefits for patients with COPD who switch to HTPs rather than continuing to smoke cigarettes. Epidemiological studies, real-world data analyses, and randomised clinical trials must be conducted to determine whether switching from cigarettes to HTPs can improve health outcomes in patients with COPD who would otherwise continue to smoke combustible cigarettes.
