Evidence for a Causal Relationship Between Academic Achievement and Cigarette Smoking.

INTRODUCTION: Academic achievement (AA) is associated with smoking rates. Can we determine the degree to which this relationship is likely a causal one? METHODS: We predict smoking in male conscripts (mean age 18.2) assessed from 1984 to 1991 (N = 233 248) and pregnant females (mean age 27.7) receiving prenatal care 1972-1990 (N = 494 995) from AA assessed in all students at 16. Instrumental variable (IV) analyses used the instrument month-of-birth as in each school year, older children have high AA. Co-relative analyses used AA-smoking associations in the population, cousins and siblings to predict the AA-smoking relationship in MZ twins, thereby controlling for familial confounding. RESULTS: In males, higher AA was associated with a substantial decrease in risk for smoking (odds ratio [OR] [95% confidence intervals [CIs]] per standard deviation [SD] = 0.41 [0.40-0.41]) while the parallel figures obtain from our IV and co-relative analyses were 0.47 (0.39-0.57) and 0.51 (0.43-0.60), respectively. In females, these figures for pre-pregnancy smoking were, respectively, 0.39 (0.39-0.39), 0.50 (0.46-0.54) and 0.54 (0.51-0.58). Results for heavy versus light smoking suggested a causal effect but were inconsistent across methods. However, among females smoking prior to pregnancy, AA predicted a reduced risk for continued smoking with ORs for uncontrolled, IV, and co-relative analyses equaling, respectively, were 0.54 (0.53-0.55) 0.68 (0.56-0.82) and 0.78 (0.66-0.91), respectively. CONCLUSIONS: Two different methods produced consistent evidence that higher AA has a causal effect on reducing smoking rates and increasing cessation rates in smoking pregnant females. Improving AA may result in meaningful gains in population health through reduced smoking. IMPLICATIONS: This study provides consistent evidence across two different methods that high AA is causally related to reduced rates of smoking and increasing rates of smoking cessation among pregnant women. Our results suggest that interventions that improve educational achievement in adolescence would reduce tobacco consumption, thereby improving public health.

Effect of e-Cigarettes Plus Counseling vs Counseling Alone on Smoking Cessation: A Randomized Clinical Trial.

Importance: Electronic cigarettes (e-cigarettes) for smoking cessation remain controversial. Objective: To evaluate e-cigarettes with individual counseling for smoking cessation. Design, Setting, and Participants: A randomized clinical trial enrolled adults motivated to quit smoking from November 2016 to September 2019 at 17 Canadian sites (801 individuals screened; 274 ineligible and 151 declined). Manufacturing delays resulted in early termination (376/486 participants, 77% of target). Outcomes through 24 weeks (March 2020) are reported. Interventions: Randomization to nicotine e-cigarettes (n = 128), nonnicotine e-cigarettes (n = 127), or no e-cigarettes (n = 121) for 12 weeks. All groups received individual counseling. Main Outcomes and Measures: The primary end point was point prevalence abstinence (7-day recall, biochemically validated using expired carbon monoxide) at 12 weeks, changed from 52 weeks following early termination. Participants missing data were assumed to be smoking. The 7 secondary end points, examined at multiple follow-ups, were point prevalence abstinence at other follow-ups, continuous abstinence, daily cigarette consumption change, serious adverse events, adverse events, dropouts due to adverse effects, and treatment adherence. Results: Among 376 randomized participants (mean age, 52 years; 178 women [47%]), 299 (80%) and 278 (74%) self-reported smoking status at 12 and 24 weeks, respectively. Point prevalence abstinence was significantly greater for nicotine e-cigarettes plus counseling vs counseling alone at 12 weeks (21.9% vs 9.1%; risk difference [RD], 12.8 [95% CI, 4.0 to 21.6]) but not 24 weeks (17.2% vs 9.9%; RD, 7.3 [95% CI, -1.2 to 15.7]). Point prevalence abstinence for nonnicotine e-cigarettes plus counseling was not significantly different from counseling alone at 12 weeks (17.3% vs 9.1%; RD, 8.2 [95% CI, -0.1 to 16.6]), but was significantly greater at 24 weeks (20.5% vs 9.9%; RD, 10.6 [95% CI, 1.8 to 19.4]). Adverse events were common (nicotine e-cigarette with counseling: 120 [94%]; nonnicotine e-cigarette with counseling: 118 [93%]; counseling only: 88 [73%]), with the most common being cough (64%) and dry mouth (53%). Conclusions and Relevance: Among adults motivated to quit smoking, nicotine e-cigarettes plus counseling vs counseling alone significantly increased point prevalence abstinence at 12 weeks. However, the difference was no longer significant at 24 weeks, and trial interpretation is limited by early termination and inconsistent findings for nicotine and nonnicotine e-cigarettes, suggesting further research is needed.

Cannabis cessation among youth: rates, patterns and academic outcomes in a large prospective cohort of Canadian high school students. / Abandon du cannabis chez les jeunes : taux, tendances et résultats scolaires dans une vaste cohorte prospective d'élèves canadiens du secondaire.

INTRODUCTION: Following cannabis legalization in Canada, a better understanding of the prevalence of unprompted cannabis use reduction and subsequent effects on youth academic outcomes is needed to inform harm reduction and health promotion approaches. METHODS: We analyzed a longitudinally linked sample (n = 91774) from the COMPASS prospective cohort study of Canadian high school students attending Grades 9-12 in Ontario and Alberta between 2013-2014 and 2016-2017. We investigated the prevalence of spontaneous cannabis use reduction and cessation between grade transitions (Grades 9-10, 10-11, 11-12) and the effect of cessation on academic achievement (current or recent math and English course marks) and rigour (usual homework completion and past-month truancy). RESULTS: Only 14.8% of cannabis users decreased their use between grades. Of these, two-thirds made only incremental downward changes, a pattern which held true for all three transitions. Cessation rates from daily and weekly use decreased every year. After cessation, students had better odds than continuing users (OR = 1.23, 95% CI: 1.03- 1.48) and worse odds than never-users (OR = 0.55, 95% CI: 0.31-0.97) for some subcategories of math performance. Students who quit cannabis universally improved class attendance (OR = 2.48, 95% CI: 1.93-3.19) and homework completion (OR = 2.32, 95% CI: 1.85-2.92) compared to continuing users. CONCLUSION: Increased academic rigour may underlie any improvements seen in academic performance after cannabis cessation. High school students who use cannabis likely need targeted support to facilitate reduction or cessation and subsequent academic recovery. This indicates that a school-based focus on cannabis harm reduction is justified.

Is dual use of nicotine products and cigarettes associated with smoking reduction and cessation behaviours? A prospective study in England.

OBJECTIVES: To investigate associations of dual use of e-cigarettes and cigarettes with subsequent quitting activity (smoking reduction, quit attempts and use of evidence-based cessation aids). To overcome potential confounding by factors associated with use of pharmacological support, we selected dual use of over-the-counter nicotine replacement therapy (OTC NRT) and cigarettes as a behavioural control. DESIGN: Prospective cohort study with 6-month follow-up. SETTING: England, 2014-2016. PARTICIPANTS: 413 current smokers participating in the Smoking Toolkit Study, a representative survey of adults in England, who reported current use of e-cigarettes or OTC NRT and provided data at 6-month follow-up. MAIN OUTCOME MEASURES: The exposure was dual use of e-cigarettes or OTC NRT at baseline. Outcomes were change in cigarette consumption, quit attempts and use of evidence-based cessation aids during quit attempts over 6-month follow-up. Relevant sociodemographic and smoking characteristics were included as covariates. RESULTS: After adjustment for covariates, dual e-cigarette users smoked two fewer cigarettes per day at follow-up than at baseline compared with dual OTC NRT users (B=2.01, 95% CI -3.62; -0.39, p=0.015). While dual e-cigarette users had 18% lower odds than dual OTC NRT users to make a quit attempt at follow-up (risk ratio (RR) 0.82, 95% CI 0.67 to 1.00, p=0.049), the groups did not differ in use of cessation aids (RR 1.06, 95% CI 0.93 to 1.21, p=0.388). CONCLUSIONS: Dual use of e-cigarettes is associated with a greater reduction in cigarette consumption than dual use of OTC NRT. It may discourage a small proportion of users from making a quit attempt compared with dual OTC NRT use but it does not appear to undermine use of evidence-based cessation aids.

Male smoking reduction behaviour in response to China's 2015 cigarette tax increase.

OBJECTIVE: This study aims to evaluate Chinese male smokers' responses to China's 2015 6% ad valorem and RMB0.1 specific excise tax increase per cigarettes pack. METHODS: A male population-based cross-sectional survey with multistaged stratified sampling was employed to collect data in six cities in China. Descriptive methods and logistic models were used to assess responses and associated factors following the cigarette tax increase among male Chinese smokers. RESULTS: Among a potential sample of 6500 Chinese males, 6010 individuals were contacted and 5782 participants completed the questionnaires. Of the 2852 current smokers, 60.7% (95% CI: 58.9 to 62.5) did not think cigarettes were expensive, 77.9% (95% CI: 76.4 to 79.5) reported no reduction in smoking in response to the 2015 tax increase and 21.3% (95% CI: 19.8 to 22.8) were not aware of the cigarette tax increase. Smokers who were occasional smokers, intended to quit and thought cigarettes expensive were more likely to report reducing cigarette smoking following the tax increase, while those who had higher household income per capita, smoked more cigarettes, and purchased more expensive cigarettes were less likely to report reducing cigarette consumption. CONCLUSIONS: About one in five male Chinese smokers reported reduction in smoking following China's 2015 cigarette tax increase. This is a relatively large impact given the very modest tax increase. Even with the 2015 increase, the excise tax represents only 36.3% of the cigarette price in China. Tax increases are needed to achieve the WHO's recommended level of 70%.

Better Health Choices: Feasability and preliminary effectiveness of a peer delivered healthy lifestyle intervention in a community mental health setting.

BACKGROUND: To reduce smoking and improve other health behaviours of people living with severe mental illness, healthy lifestyle interventions have been recommended. One approach to improving the availability of these types of interventions is to utilise the mental health peer workforce. The current study aimed to evaluate the feasibility of peer-workers facilitating a telephone delivered healthy lifestyle intervention within community based mental health settings. The study also examined preliminary outcomes of the intervention. METHODS: The study was conducted as a randomised controlled feasibility trial. In addition to treatment as usual, participants randomised to the Treatment Condition were offered BHC. This was an 8-session telephone delivered coaching intervention that encouraged participants to decrease their smoking, increase their intake of fruit and vegetables, and reduce their leisure screen time. Participants in the waitlist Control Condition continued to complete treatment as usual. All participants were engaged with Neami National, an Australian community mental health organisation. Peer-workers were also current employees of Neami National. RESULTS: Forty-three participants were recruited. The average number of sessions completed by participants in the Treatment Condition was 5.7 (SD = 2.6; out of 8-sessions). Seventeen participants (77%) completed at least half of the sessions, and nine participants (40%) completed all eight sessions. Participant satisfaction was high, with all participants followed up rating the quality of the service they received as 'good' or 'excellent'. When compared to the Control Condition, people in the Treatment Condition demonstrated greater treatment effects on smoking and leisure screen time. There was only a negligible effect on servings of fruit and vegetable. CONCLUSIONS: Results were promising regarding the feasibility of peer-workers delivering BHC. Good retention rates and high consumer satisfaction ratings in the Treatment Condition demonstrated that peer-workers were capable of delivering the intervention to the extent that consumers found it beneficial. The current results suggest that a sufficiently powered, peer delivered randomised controlled trial of BHC is warranted.

Effect of Electronic Cigarettes on Smoking Reduction and Cessation in Korean Male Smokers: A Randomized Controlled Study.

INTRODUCTION: New approaches to electronic cigarettes (e-cigarettes) as a form of nicotine replacement therapy (NRT) may reduce the rates of tobacco-related disease and mortality. Therefore, we investigated the effect of e-cigarettes on smoking cessation compared with nicotine gum. METHODS: A total of 150 subjects were randomly assigned to 2 groups and each was allocated a 12-week supply of either e-cigarettes or nicotine gum. The continuous abstinence rate, 7-day point prevalence of abstinence, smoking reduction rate and amount, and tolerability were evaluated. RESULTS: There were no statistically significant differences in the effectiveness-related parameters of smoking cessation, such as 9- to 12-week, 9- to 24-week, and 12- and 24-week point prevalence of abstinence, between the 2 groups. However, although the reduction in cigarette smoking was similar, the proportion of subjects who showed smoking reduction at 24 weeks was higher in the e-cigarette group than the nicotine gum group. In addition, adverse events were significantly less frequent in the e-cigarette group than in the nicotine gum group. CONCLUSIONS: In our study, the effect of e-cigarettes on smoking cessation was similar compared with that of nicotine gum, a well-documented NRT. In addition, e-cigarettes were well tolerated by the study population. Therefore, the use of e-cigarettes as an NRT may be considered for smoking-cessation purposes. A large-scale prospective randomized controlled trial is necessary to clarify our results.

Correlates of electronic cigarette use in the general population and among smokers in Australia - Findings from a nationally representative survey.

AIMS: In Australia, sales of nicotine containing electronic cigarettes (also known as e-cigarette) are banned unless approved as a therapeutic good. The aims of this study were to estimate the prevalence of e-cigarette use and its correlates in Australia using a nationally representative survey. METHOD: We analysed data from the largest drug use survey in Australia (the National Drug Strategy Household Survey [NDSHS]; N = 22,354). RESULTS: We estimated that 227,000 Australians (1.2% of the population) were current e-cigarettes users, and 97,000 (0.5%) used them daily. Individuals who were male, younger, had higher level of psychological distress, and smoked were more likely to use electronic cigarettes. Among smokers, an intention to quit and reduction in smoking was associated with experimentation and daily use of e-cigarette, but not with occasional use. Recent quitting was associated with daily use. CONCLUSION: Overall, the prevalence of e-cigarette use was low in 2016 in Australia. Smoking status was the strongest correlates of e-cigarette use. Patterns of vaping were differentialy associated with an intention to quit smoking, smoking reduction and recent quitting. Some smokers may attempt to use e-cigarettes to cut-down their tobacco use, and those who vaped daily were mostly likely to be recent quitters.

Self-initiated gradual smoking reduction among community correction smokers.

INTRODUCTION: Smoking remains the leading cause of preventable death in the United States. Many smoking cessation guidelines advise smokers to quit precipitately; however, most quit attempts involve a more gradual cessation. Characteristics of individuals who tend to reduce prior to quitting and the effectiveness of pre-quit reduction are not well understood. This study examined individual differences and smoking cessation outcomes between individuals who self-initiated gradual reduction in cigarettes per day (CPD) and those who did not reduce prior to quit date. METHODS: This study is a secondary analysis from a randomized clinical trial of smoking cessation with pharmacotherapy among individuals under community corrections supervision. We compared participants who self-initiated smoking reduction by at least 25% between baseline and the first treatment session (n = 128) to participants who either increased or did not reduce smoking between baseline and the first treatment session (n = 354). RESULTS: African American race, no previous cigar smoking, no previous use of pharmacotherapy for smoking cessation, less withdrawal symptoms at baseline, and older age at first smoking were associated with being a self-initiated gradual reduction in univariate analyses. Individuals who self-initiated gradual reduction also had a had a greater likelihood of achieving at least one quit during the one-year study period as compared to those who did not reduce prior to the intervention. CONCLUSIONS: Individuals who self-initiate gradual reduction differ from those who increase or do not change their smoking prior to a quit date. Gradual reduction also increased success in quitting.

Quitting Behaviors Among Dual Cigarette and E-Cigarette Users and Cigarette Smokers Enrolled in the Tobacco User Adult Cohort.

PURPOSE: We examined quitting behaviors among a cohort of dual users (cigarettes and electronic cigarettes [e-cigarettes]) and exclusive cigarette smokers for: (1) cigarette smoking reduction, (2) quit attempts, (3) abstinence from cigarettes, and (4) abstinence from all tobacco products. METHODS: Participants enrolled in the Tobacco User Adult Cohort and categorized as "daily" user of cigarettes and "daily" or "some days per week" use of e-cigarettes (ie, dual users; n = 88) or "daily" user of cigarettes only (ie, cigarette smokers; n = 617) served as the analytic sample. Participants were interviewed face to face every 6 months, through 18 months. Data on self-reported current product(s) used, cessation interest, quit attempts and abstinence from cigarettes, and all tobacco products were collected. RESULTS: No difference in reduction of cigarette consumption over time was noted between groups. Rates of reporting an attempt to quit all tobacco products (≥ 24 hours of not using any tobacco in an attempt to quit) also did not differ by group. Compared to cigarette smokers, dual users were more likely to report abstinence from cigarettes at 6 months (OR = 2.54, p = .045) but not at 12 or 18 months. There was no significant difference in abstinence from all tobacco products by group at 6, 12, or 18 months. CONCLUSIONS: Although dual use of e-cigarettes has been cited as a potential cessation tool for cigarette smokers, our findings indicated that this association was only observed in the short term. We also found no evidence of any association between dual use and eventual abstinence from all tobacco products. IMPLICATIONS: Our study observed that, in the natural environment, dual users of cigarettes and e-cigarettes were more likely than cigarette smokers to quit cigarettes in the short term but no more likely to quit using cigarettes and all tobacco products over time.

Tailored Intervention for Smoking Reduction and Cessation for Young and Socially Disadvantaged Women During Pregnancy.

Rates of smoking during pregnancy remain high in Canada, and cessation rates are low among women who are younger than 24 years and who are socially disadvantaged, that is, have few social and economic resources because of poverty, violence, or mental health issues. On the basis of findings from literature reviews and consultation with policy makers, we developed and operationalized four approaches that can be used by health care providers to tailor interventions for tobacco use in pregnancy. These four approaches are woman centered, trauma informed, harm reducing, and equitable. Public health initiatives that address smoking in young and socially disadvantaged women could be more sharply focused by shifting to such tailored approaches that are grounded in social justice aims, span pre- and postpregnancy periods, and can be used to address women's social contexts and concerns.

Trends in risk and protective factors for non-communicable diseases in the population with health insurance in Brazil from 2008 to 2015. / Tendências de fatores de risco e proteção de doenças crônicas não transmissíveis na população com planos de saúde no Brasil de 2008 a 2015.

OBJECTIVE: To analyze trends in risk and protective factors for non-communicable diseases (NCD) and access to preventive tests in the population with health insurance in Brazilian state capitals between 2008 and 2015. METHODS: This is a cross-sectional study that analyzed data collected from the Surveillance of Risk and Protective Factors for non-communicable diseases (NCD) Telephone Survey (Sistema Nacional de Vigilância de Doenças Crônicas por Inquérito Telefônico - Vigitel) on adults aged 18 years and older. We analyzed trends in NCD indicators among health insurance users in approximately 30 thousand interviews done between 2008 and 2015. We used the simple linear regression model to calculate the trends. RESULTS: Health insurance users showed an increase in the prevalence of protective factors such as fruit and vegetable consumption, and physical activity in leisure time. Also, there was a decrease in risk factors such as smoking and soft drink consumption, increase in mammography coverage, and a drop in smoking prevalence. However, overweight, obesity, and diabetes increased. CONCLUSION: There are differences according to gender, and, in general, women accumulate more protective factors and men, more risk factors.

OBJETIVO: Analisar as tendências de fatores de risco e proteção de doenças crônicas não transmissíveis (DCNT) e do acesso a exames preventivos na população com planos de saúde nas capitais brasileiras entre 2008 e 2015. MÉTODOS: Trata-se de estudo transversal, analisando dados coletados do Sistema Nacional de Vigilância de Doenças Crônicas por Inquérito Telefônico (Vigitel), de adultos com 18 anos e mais. Foram analisadas tendências de indicadores de DCNT entre os usuários de planos de saúde, em cerca de 30 mil entrevistas a cada ano, entre 2008 e 2015. Utilizou-se o modelo de regressão linear simples para o cálculo das tendências. RESULTADOS: Usuários de planos de saúde apresentaram aumento das prevalências de fatores de proteção como o consumo de frutas e legumes e atividade física no lazer; houve redução de fatores de risco como tabagismo, consumo de refrigerantes, aumento na cobertura de mamografia e declínio na prevalência do tabagismo. Entretanto, ocorreu aumento do excesso de peso, obesidade e diabetes. CONCLUSÃO: Existem diferenças segundo sexo, e em geral as mulheres acumulam mais fatores de proteção e homens, mais fatores de risco.

Variation across Romania in the health impact of increasing tobacco taxation.

Background: Tobacco is the leading preventable cause of death globally and tobacco taxation is a cost-effective method of reducing tobacco use in countries and increasing revenue. However, without adequate enforcement some argue the risk of increasing illicit trade in cheap tobacco makes taxation ineffective. We explore this by testing sub-national variations in the impact of tobacco tax increases from 2009 to 2011, on seven smoking-related diseases in adults in Romania, to see if regions that are prone to cigarette smuggling due to bordering other countries see less benefit. Method: We use a pragmatic natural experiment study approach to analyse the study period 2009-15. Findings from hospital episodes data relating to smoking-attributable diseases are analysed for six regional subgroups which are compared according to border characteristics with other countries. Results: At a national level smoking-attributable diseases reduced over the study period especially around the tax increase years, with asthma showing the most significant decline. Sub-nationally there was no statistically significant correlation in variations between central regions and those bordering other countries. Conclusion: There is a reassuring decline in hospitalizations for smoking-related diseases associated with the tax increases, and no sub-national association with smuggling risk measured by variation in the size of this effect and regions that border other countries. More comprehensive and progressive tobacco control in Romania should be implemented in line with the WHO Framework Convention for Tobacco Control.

A Cluster Randomized Controlled Trial of a Total Worker Health® Intervention on Commercial Construction Sites.

This study evaluated the efficacy of an integrated Total Worker Health® program, "All the Right Moves", designed to target the conditions of work and workers' health behaviors through an ergonomics program combined with a worksite-based health promotion Health Week intervention. A matched-pair cluster randomized controlled trial was conducted on ten worksites (five intervention (n = 324); five control sites (n = 283)). Worker surveys were collected at all sites pre- and post- exposure at one- and six-months. Linear and logistic regression models evaluated the effect of the intervention on pain and injury, dietary and physical activity behaviors, smoking, ergonomic practices, and work limitations. Worker focus groups and manager interviews supplemented the evaluation. After controlling for matched intervention and control pairs as well as covariates, at one-month following the ergonomics program we observed a significant improvement in ergonomic practices (B = 0.20, p = 0.002), and a reduction in incidences of pain and injury (OR = 0.58, p = 0.012) in the intervention group. At six months, we observed differences in favor of the intervention group for a reduction in physically demanding work (B = -0.25, p = 0.008), increased recreational physical activity (B = 35.2, p = 0.026) and higher consumption of fruits and vegetables (B = 0.87, p = 0.008). Process evaluation revealed barriers to intervention implementation fidelity and uptake, including a fissured multiemployer worksite, the itinerant nature of workers, competing production pressures, management support, and inclement weather. The All the Right Moves program had a positive impact at the individual level on the worksites with the program. For the longer term, the multi-organizational structure in the construction work environment needs to be considered to facilitate more upstream, long-term changes.

The Value of Providing Smokers with Free E-Cigarettes: Smoking Reduction and Cessation Associated with the Three-Month Provision to Smokers of a Refillable Tank-Style E-Cigarette.

Despite the uptake of tobacco smoking declining in the United Kingdom (UK), smoking is still the leading cause of preventable poor health and premature death. While improved approaches to smoking cessation are necessary, encouraging and assisting smokers to switch by using substantially less toxic non-tobacco nicotine products may be a possible option. To date, few studies have investigated the rates of smoking cessation and smoking reduction that are associated with the provision of free electronic-cigarettes (e-cigarettes) to smokers. In this exploratory study, the Blu Pro e-cigarette was given to a convenience sample of adult smokers (n = 72) to assist them in reducing and quitting over a 90-day period. The rates of smoking abstinence and daily smoking patterns were assessed at baseline, 30 days, 60 days, and 90 days. The response rate was 87%. After 90 days, the complete abstinence rate was 36.5%, up from 0% at baseline. The frequency of daily smoking reduced from 88.7% to 17.5% (p < 0.001), and the median consumption of cigarettes/day reduced from 15 to five (p < 0.001). The median number of days per month that participants smoked also reduced from 30 to 13 after 90 days (p < 0.001). On the basis of these results, there may be value in smoking cessation services and other services ensuring that smokers are provided with e-cigarettes at zero or minimal costs for at least a short period of time.

Flavored E-cigarette Use and Cigarette Smoking Reduction and Cessation-A Large National Study among Young Adult Smokers.

BACKGROUND: E-cigarette use prevalence has increased drastically among young adult cigarette smokers in recent years. OBJECTIVES: This study seeks to understand which e-cigarette flavors-sweet and fruity or tobacco and menthol/mint-are more likely to be associated with smoking reduction and cessation among young adults. METHODS: Longitudinal data (waves 1 and 2) of the Population Assessment of Tobacco and Health (PATH) Study from young adult (aged 18-34) cigarette smokers (n = 4,645) at wave 1 and current e-cigarette users (n = 844) at wave 2 were used. Univariate and multivariate regressions were conducted to examine the associations between past-year smoking reduction and cessation and current e-cigarette flavor use at wave 2. RESULTS: At wave 2, 25.9% of respondents either reduced or quit smoking, and 6.7%, 5.2%, and 6.3% of them reported currently using e-cigarettes with tobacco/menthol (TM) flavors, one non-tobacco/non-menthol (NTM) flavor, and multiple NTM flavors, respectively. E-cigarette users with one (AOR = 2.5, p < 0.001) and multiple NTM flavors (AOR = 3.0, p < 0.001) were more likely to have reduced or quit smoking over the past year compared to non-e-cigarette users. NTM flavor use was positively associated with e-cigarette use of a higher frequency and larger amount. CONCLUSIONS: The positive association between past-year smoking reduction and cessation and current NTM flavored e-cigarette use may be explained by young adults' escalated e-cigarette use with NTM flavors. Public health professionals should prevent and reduce multiple tobacco use through enhanced education about the harm of vaping NTM flavors and by advising young adult smokers to quit tobacco altogether using evidence-based methods.

Comparison of two approaches in achieving smoking abstinence among patients in an outpatient clinic: A Phase 2 randomized controlled trial.

OBJECTIVES: To compare the effectiveness of quitting immediately and cutting down to quit in promoting smoking abstinence among smokers in an outpatient clinic. METHODS: A total of 100 subjects were randomized into two groups, 50 in the quit immediately group, who received an intervention on abruptly quitting, and 50 in the cut down to quit group, who received an intervention on gradual reduction. All subjects were followed up at 6 and 12 months via telephone. The intention-to-treat principle was used. RESULTS: At the 6-month follow-up, the self-reported quit rate of subjects in the quit immediately group was significantly higher than in the cut down to quit group (18.0% vs. 4.0%, p = 0.04). However, this difference was not significant at the 12-month follow-up (12.0% vs. 4.0%, p = 0.16). CONCLUSION: These data suggest that quitting immediately might be more effective than cutting down to quit at 6 months but not at 12 months. PRACTICE IMPLICATIONS: It is crucial to allow smokers to select quitting immediately or reducing the number of cigarettes smoked. Further studies are warranted to compare the effectiveness of various approaches for achieving smoking abstinence.

Effect of Smoking Cessation and Reduction on the Risk of Cancer in Korean Men: A Population Based Study.

PURPOSE: The purpose of this study was to investigate the effect of smoking habit change on the risk of cancer. MATERIALS AND METHODS: From the Korean National Health Insurance Service database, we determined the change in smoking habit between the first (2002 and 2003) and second (2004 and 2005) health examination periods. A total of 143,071 men were categorized into baseline heavy (≥ 20 cigarettes per day), moderate (10-19 cigarettes per day), light (< 10 cigarettes per day) smokers, quitters, and never smokers, after which the change in smoking status was determined during the second health examination. The participants were then followed up from 2006 to 2013 for all cancer, smoking related cancer, and lung cancer. RESULTS: Compared to heavy continual smokers, heavy smokers who quit had reduced risk of smoking related cancer (hazard ratio [HR], 0.74; 95% confidence interval [CI], 0.56 to 0.97) and tended to have reduced risk of all cancer (HR, 0.87; 95% CI, 0.75 to 1.00). Moderate smokers who reduced the amount of smoking to light levels had decreased risk of all cancer (HR, 0.82; 95% CI, 0.72 to 0.94), smoking related cancer (HR, 0.74; 95% CI, 0.59 to 0.93), and lung cancer (HR, 0.55; 95% CI, 0.38 to 0.79) compared to heavy continual smokers. CONCLUSION: Smoking reduction decreases the risk of all cancer, smoking related cancer, and lung cancer. While smoking cessation should be the treatment of choice for smokers, smoking reduction may serve as an alternative strategy for those who cannot quit.

Resultados: Usuários de planos de saúde apresentaram aumento das prevalências de fatores de proteção como o consumo de frutas e legumes e atividade física no lazer; houve redução de fatores de risco como tabagismo, consumo de refrigerantes, aumento na cobertura de mamografia e declínio na prevalência do tabagismo. Entretanto, ocorreu aumento do excesso de peso, obesidade e diabetes. Conclusão: Existem diferenças segundo sexo, e em geral as mulheres acumulam mais fatores de proteção e homens, mais fatores de risco.

ABSTRACT: Objective: To analyze trends in risk and protective factors for non-communicable diseases (NCD) and access to preventive tests in the population with health insurance in Brazilian state capitals between 2008 and 2015. Methods: This is a cross-sectional study that analyzed data collected from the Surveillance of Risk and Protective Factors for non-communicable diseases (NCD) Telephone Survey (Sistema Nacional de Vigilância de Doenças Crônicas por Inquérito Telefônico - Vigitel) on adults aged 18 years and older. We analyzed trends in NCD indicators among health insurance users in approximately 30 thousand interviews done between 2008 and 2015. We used the simple linear regression model to calculate the trends. Results: Health insurance users showed an increase in the prevalence of protective factors such as fruit and vegetable consumption, and physical activity in leisure time. Also, there was a decrease in risk factors such as smoking and soft drink consumption, increase in mammography coverage, and a drop in smoking prevalence. However, overweight, obesity, and diabetes increased. Conclusion: There are differences according to gender, and, in general, women accumulate more protective factors and men, more risk factors.

Prevalence of tobacco use in selected Johannesburg suburbs.

BACKGROUND: Tobacco smoking is estimated to kill more than 44 000 South Africans every year. Studies have shown that since the introduction of tobacco control measures, national smoking prevalence has declined in South Africa (SA). OBJECTIVE: To determine the prevalence of tobacco smoking over a 7-year period in five impoverished neighbourhoods in Johannesburg, SA. METHODS: Data were collected through the annual administration of a prestructured questionnaire to one adult respondent in preselected dwellings from 2006 to 2012. Information was collected on socioeconomic status, smoking practices and health status. RESULTS: Over the 7-year period of the analysis, smoking levels remained unchanged. The proportion of households with one or more smokers varied significantly across the five study neighbourhoods. Approximately 20% of households in Hillbrow and as many as 77% in Riverlea had a member who smoked. CONCLUSIONS: Despite a national downward trend in smoking levels, tobacco use remains high and persistent in certain vulnerable communities, requiring scaled-up action to reduce the risk of a range of tobacco-related diseases.
