IMPORTANCE
President Biden recently prioritized the fight against smoking as key to reducing cancer mortality.
OBJECTIVE
To assess trends in smoking and illuminate the association between smoking and reducing deaths due to cancer.
DESIGN, SETTING, AND PARTICIPANTS
This cross-sectional study used responses to National Health Interview Surveys from January 1, 2011, to December 31, 2022, to characterize trends in current smoking for key sociodemographic groups among US adults.
EXPOSURES
Age (18-24, 25-39, 40-64, and ≥65 years), family income (<200%, 200%-399%, and ≥400% of the federal poverty level [FPL]), educational level (less than high school, high school degree or General Educational Development, some college, and college degree or above), and race and ethnicity (Black, Hispanic, White, and other).
MAIN OUTCOMES AND MEASURES
Weighted current smoking prevalence with 95% CIs by analysis group from 2011 to 2022. Average annual percentage change (AAPC) in smoking prevalence by analysis group is calculated using Joinpoint regression.
RESULTS
Data from 353 555 adults surveyed by the National Health Interview Surveys from 2011 to 2022 were included (12.6% Black, 15.0% Hispanic, 65.2% White, and 7.3% other race or ethnicity). Overall, smoking prevalence decreased among adults aged 18 to 24 years from 19.2% (95% CI, 17.5%-20.9%) in 2011 to 4.9% (95% CI, 3.7%-6.0%) in 2022 at an AAPC of -11.3% (95% CI, -13.2% to -9.4%), while it remained roughly constant among adults 65 years or older at 8.7% (95% CI, 7.9%-9.5%) in 2011 and 9.4% (95% CI, 8.7%-10.2%) in 2022 (AAPC, -0.1% [95% CI, -0.8% to 0.7%]). Among adults 65 years or older, smoking prevalence increased from 13.0% (95% CI, 11.2%-14.7%) in 2011 to 15.8% (95% CI, 14.1%-17.6%) for those with income less than 200% FPL (AAPC, 1.1% [95% CI, 0.1%-2.1%]) and remained roughly constant with no significant change for those of higher income. Similar age patterns are seen across educational level and racial and ethnic groups.
CONCLUSIONS AND RELEVANCE
This cross-sectional study found that smoking prevalence decreased from 2011 to 2022 in all age groups except adults 65 years or older, with faster decreases among younger than older adults. These findings suggest that the greatest gains in terms of reducing smoking-attributable morbidity and mortality could be achieved by focusing on individuals with low socioeconomic status, as this population has the highest smoking rates and the worst health prospects.

PURPOSE
Tobacco prevention media campaigns are an important tool to address youth tobacco use. We developed a theory-based perceived message effectiveness (PME) Scale to use when vetting messages for campaigns.
METHODS
Participants were a national sample of N=623 US adolescents (ages 13-17 years) recruited from a national probability-based panel. In an online experiment, we randomised adolescents to view tobacco prevention ads. All participants viewed an ad on smoking or vaping from the US Food and Drug Administration's campaign and a control video, in a random order. After ad exposure, we assessed PME using nine candidate items and constructs for convergent and criterion validity analyses. We used confirmatory factor analysis and examined information curves to select the scale items.
RESULTS
A brief PME scale with three items (α=0.95) worked equally well for demographically diverse adolescents with different patterns of tobacco use. ads generated higher PME scores than the control videos for both vaping and smoking (convergent validity; p<0.05). Higher PME scores were associated with greater attention, fear, cognitive elaboration and anticipated social interactions (convergent validity; r=0.31-0.66), as well as more negative attitudes toward and lower susceptibility to vaping and smoking (criterion validity; r=-0.14 to -0.37). A single-item PME measure performed similarly to the three-item version.
CONCLUSIONS
The University of North Carolina PME Scale for Youth is a reliable and valid measure of the potential effectiveness of vaping and smoking prevention ads. Employing PME scales during message development and selection may help youth tobacco prevention campaigns deploy more effective ads.

Journal of Health, Population, and... Sep 2023To examine the relationships between polyunsaturated fatty acids (PUFAs) dietary intake and asthma in children.
BACKGROUND
To examine the relationships between polyunsaturated fatty acids (PUFAs) dietary intake and asthma in children.
METHODS
In this cross-sectional study, a total of 14,727 participants from the United States National Health and Nutrition Examination Survey (NHANES) database in 1999-2018 were included, and the baseline characteristics of all participants were gathered. The description analysis was used to explore the possible covariates. Weighted multivariate logistic regression models were adopted to assessed the association between PUFAs dietary intake and asthma in children. In addition, we also performed subgroup analysis based on gender, age, and maternal smoking during pregnancy to investigate this relationship.
RESULTS
The prevalence of asthma approximately was 15.38% in the present study. The result of weighted multivariate logistic regression indicated that, docosahexaenoic [weighted odds ratio (OR) = 0.37, 95% confidence interval (CI) 0.19-0.74], total n - 3 PUFAs (weighted OR = 0.63, 95%CI 0.43-0.91), and eicosapentaenoic (weighted OR = 0.35, 95%CI 0.13-0.95) dietary intake were negatively associated with asthma in children. The subgroup analysis described that when children were male (weighted OR = 0.28, 95%CI 0.10-0.84), or were 5-7 years (weighted OR = 0.04, 95%CI 0.01-0.37), were 7-12 years (weighted OR = 0.46, 95%CI 0.24-0.90), or their maternal smoking during pregnancy (weighted OR = 0.16, 95%CI 0.03-0.90), docosahexaenoic dietary intake was negatively related to childhood asthma.
CONCLUSION
Docosahexaenoic dietary intake was negatively associated with the asthma in children, especially if children were male, or were 5-12 years, or their maternal smoking during pregnancy.

INTRODUCTION
An Internet questionnaire was used to determine smoking behavior, purchasing behavior, and risk perceptions among exclusive or nearly exclusive current users of either large manufactured (LMC) or premium cigars (PC).
AIMS AND METHODS
Respondents (n = 250) were recruited from a nationally representative market research panel. An a priori designation of PC users was adapted from criteria in published literature and the recent National Academy of Science report.
RESULTS
Examination of responses revealed a (n = 19) disagreement between cigar users' self-classifications and the a priori classification. After eliminating ineligible respondents 188 participants were classified as PC (n = 92; 55 male) or LMC (n = 96; 49 male) users. There were no significant differences in age or gender between groups. Respondents were all over 21 years old. The largest age groups were 30-39 years and 60-69 years. PC users were significantly more likely to have higher annual incomes and to buy cigars online or through tobacco specialty shops, whereas LMC users purchased from convenience stores. Most participants had used other combustible tobacco products (88%) but few had used ENDS (24%) or oral tobacco (7.5%). There was no significant difference in the frequency of smoke inhalation or perceptions of risk for health. There was marked uncertainty in self-characterization of cigar type; our sample had higher female representation than expected (n = 84, 45%), and inhalation was frequently endorsed in both groups (52%, overall).
CONCLUSIONS
The results support the need for standardized classifications and suggest current trends may indicate shifts in gender and use behavior but provide no evidence supporting less restrictive regulation of PC.
IMPLICATIONS
An Internet questionnaire was used to determine smoking behavior, purchasing behavior, and risk perceptions among current users of LMC or PC. There was uncertainty about cigar classification even in this sample of regular users. Our results demonstrated more than expected inhalation of cigar smoke, considerable use by females, and under appreciation of health risks. No results supported less restrictive regulations for premium cigars.

Meta-Analysis Review
BACKGROUND
Smoking history is a heterogeneous situation for different populations, and numerous studies suggest that smoking cessation is conducive to reduce the mortality of lung cancer. However, no quantitative meta-analysis regarding smoking cessation duration based on different populations has demonstrated it clearly.
METHODS
We systematically searched four electronic databases (PubMed, Embase, the Cochrane Central Register of Controlled Trials, and Scoups) till February 2023. Eligible studies reported the association between lung cancer survival and duration of smoking cessation. Additionally, we stratified the study population according to whether they had lung cancer at the time they quit smoking. Studies were pooled with the random-effects model.
RESULTS
Out of the 11,361 potential studies initially identified, we included 24 studies involving 969,560 individuals in our analysis. Lung cancer mortality varied across two groups: general quitters and peri-diagnosis quitters. For general quitters, those who had quit smoking for less than 10 years exhibited an RR of 0.64 (95% CI [0.55-0.76]), while those who quit for 10-20 years had an RR of 0.33 (0.25-0.43), over 20 years had an RR of 0.16 (0.11-0.24), and never-smokers had an RR at 0.11 (0.07-0.15). Among peri-diagnosis quitters, the 1-year Overall Survival (OS) showed an RR of 0.80 (0.67-0.96), the 2-year OS had an RR of 0.89 (0.80-0.98), the 3-year OS had an RR of 0.93 (0.84-1.03), and the 5-year OS had an RR of 0.85 (0.76-0.96).
CONCLUSIONS
Earlier and longer smoking cessation is associated with reduced lung cancer mortality, no matter in which cessation stage for two different populations.

INTRODUCTION
The interaction between smoking and asthma impairs lung function and increases airflow obstruction severity. The identification of smoking patterns in smokers with and without asthma is crucial to provide the best care strategies. The aims of this study are to estimate asthma frequency, describe asthma features, and characterize smoking in smokers attending smoking cessation units.
MATERIAL AND METHODS
We carried out a cross-sectional study in five smoking cessation units with different geographical distribution to estimate asthma frequency in smokers, characterize asthma features in smokers, as well as smoking in asthmatic smokers.
RESULTS
Asthma frequency among smokers was 18.6%. Asthmatic smokers presented high passive exposure, low smoking self-efficacy and will to quit smoking, as well as a high exacerbation frequency, severe symptoms, and frequent use of long-acting beta agonists, inhaled steroids, and short-acting beta agonists.
DISCUSSION
Smokers with asthma constitute a high-risk group with worsened evolution of pulmonary involvement. All smokers should be regularly screened for asthma. Effective smoking cessation strategies should be proposed to smokers with asthma in order to reverse the harmful effects of smoking on the airway, together with a comprehensive and integral approach.

OBJECTIVES
Tobacco use ranks among the leading preventable causes of death worldwide. This study was conducted to calculate the mortality rate attributable to smoking in Korea for 2019 and to highlight the importance of tracking and monitoring smoking-related deaths for public health purposes.
METHODS
Population attributable risk (PAR) was used to estimate the number of deaths related to smoking in 2019. PAR percentages were applied to the estimated mortality figures for various diseases, with PAR determined based on relative risk (RR). Levin's formula was used to calculate PAR, and RR was adjusted for age and alcohol consumption using Cox proportional hazards regression model to derive disease-specific regression coefficients. The analysis incorporated previously determined smoking rates from 1985, and use rates of novel tobacco products were not considered.
RESULTS
The findings revealed a total of 67,982 smoking-attributable deaths in Korea in 2019, 56,993 of which occurred in men and 11,049 in women. The PAR of smoking for various causes of death in adult men was highest for lung cancer at 74.9%, followed by pneumonia (29.4%), ischemic heart disease (42.3%), and stroke (30.2%). For women, the PAR for smoking-related death was highest for lung cancer (19.9%), followed by stroke (7.6%), pneumonia (5.7%), and ischemic heart disease (9.1%).
CONCLUSIONS
In countries experiencing rapid fluctuations in smoking rates, including Korea, regular studies on smoking-related mortality is imperative. Furthermore, it is necessary to investigate smoking-related deaths, including the prevalence of novel tobacco product use, to accurately gauge the risks associated with emerging tobacco products.

BACKGROUND
Chronic obstructive pulmonary disease (COPD) is the third leading cause of death in the world with nearly 90% of cases caused by tobacco smoking. Nearly 40% of people with COPD are diagnosed with depression which impacts quality of life and smoking cessation. The purpose of this study was to describe factors influencing smoking behaviors and readiness to change in people with comorbid COPD and depression.
METHODS
A descriptive cross-sectional design was used. A convenience sample of 222 participants self-reported and/or had a documented diagnosis of COPD. Participants completed study measures which included the PHQ-9 for depressive symptoms, assessment of smoking behaviors using The Cigarette Dependence Scale, report of readiness to change using The Smoking Stage of Change Questionnaire, The Smoking Decisional Balance Questionnaire, and The Processes of Change Questionnaire. Electronic and paper questionnaires were used. Data was stored in RedCap and analyzed using SPSS version 26. Based on variable type, descriptive and comparative analyses were conducted using ANOVA, t-test, chi-square, Pearson correlation, linear regression, and multiple linear regression to determine the relationships between smoking behaviors, COPD, and depressive symptoms.
RESULTS
Only 18 participants were classified as having no depressive symptoms. Participants who smoked had high nicotine dependence and wanted to quit smoking. Overall, participants saw more cons to smoking and were engaged in the processes of change. The majority of participants were in the maintenance or contemplation stage. Cigarette dependence could decrease by 9% if depressive symptoms are treated.
CONCLUSIONS
There is a need to assess COPD patients for depression and to assess COPD patients' smoking behaviors and readiness to change. Adequate treatment of depression could promote an individual to move through the stages of change from chronic contemplation to action, thus improving smoking cessation efforts for individuals with COPD. Understanding patients' smoking behaviors and readiness to change can aid in developing personalized interventions to achieve smoking cessation and improve long-term outcomes.

BACKGROUND
Smoking and drinking alcohol both significantly contribute to mortality and morbidity, and there is a need to characterise the sociodemographic and health-related characteristics (e.g. mental distress) of people who do both in order to target resources. This study reports the prevalence and characteristics of adults in the general population in England who both drink alcohol at increasing-and-higher-risk levels and smoke.
METHODS
We used cross-sectional data from a monthly, nationally representative survey of adults in England (n = 37,258; April 2020-March 2022). Weighted data were used to report prevalence and unweighted data were used to report descriptive statistics for sociodemographic and health-related characteristics.
RESULTS
The prevalence of both smoking and increasing-and-higher-risk drinking was 4.6% (95% CI = 4.4-4.9; n = 1,574). They smoked a mean of 10.4 (SD = 8.86) cigarettes per day and had a mean AUDIT score of 12.8 (SD = 5.18). Nearly half (48.2%, n = 751) were trying to cut down on their smoking and 28.0% (n = 441) on their drinking. A quarter (25.3%, n = 397) had received General Practitioner advice on smoking while 8.7% (n = 76) had received advice on their drinking. Nearly half (48.6%, n = 745) reported experiencing psychological distress in the past month and 44.6% (n = 529) had a diagnosed mental health condition, both of which were higher than among all adults (28.1% and 29.1%, respectively).
CONCLUSION
In England, from April 2020 to March 2022, the prevalence of both smoking and increasing-and-higher-risk drinking was 4.6%. This group appears to experience high rates of mental health problems and targeted support is needed.

INTRODUCTION
Improved understanding of health conditions associated with premium cigar smoking can inform efforts to reduce cigar use. This paper extends findings commissioned for the National Academies of Science, Engineering, and Medicine report on premium cigars.
AIMS AND METHODS
We pooled 2010-2019 National Survey on Drug Use and Health data to evaluate cross-sectional associations between premium cigar smoking and mental health and substance use conditions among U.S. adults. A series of logistic regression models adjusted for age, sex, race and ethnicity, cigarette smoking, and alcohol consumption compared odds of each condition associated with past-month premium cigar smoking relative to past-month nonpremium cigar smoking, never tobacco use, and current established cigarette smoking.
RESULTS
Premium cigar smoking was associated with lower adjusted odds of past month serious psychological distress, past year major depressive episode, and cannabis and illicit drug dependence relative to nonpremium cigar and cigarette smoking; however, higher odds of alcohol and cannabis dependence were observed relative to never tobacco use, and lower odds of alcohol dependence were observed relative to current cigarette smoking but not current nonpremium cigar smoking.
CONCLUSIONS
We observed considerable variation in both magnitude and direction of associations between premium cigar smoking and mental health and substance use indicators depending on the condition and reference group to which premium cigar smoking was compared.
IMPLICATIONS
Premium cigar smoking frequently cooccurs with cigarette smoking and alcohol consumption, thus potential health correlates must be considered in appropriate context. We observed considerable variation in direction and magnitude of association depending on the health condition and reference population, as well as potential for reverse causality and residual confounding in this cross-sectional analysis. As the tobacco landscape continues to evolve, rigorous scientific studies that incorporate clear differentiation of cigar type, measures of cumulative use, and temporal data collection are necessary to fully evaluate the health effects of premium cigar smoking and effectively inform Food and Drug Administration regulation.
