Anxiety Sensitivity and Distress Tolerance in Relation to Smoking Abstinence Expectancies Among Black Individuals Who Smoke

OBJECTIVE

Black individuals who smoke in the United States experience significant tobacco-related disparities. Although prior work has established that smoking abstinence expectancies play an important role in smoking-related outcomes, few studies have examined potential individual difference factors that may be relevant to smoking abstinence expectancies among Black individuals who smoke. The present study investigated anxiety sensitivity and distress tolerance in relation to smoking abstinence expectancies among a sample of Black individuals who smoke.

METHOD

Participants were 86 Black adults who smoke cigarettes daily (M age = 46.07 years, SD = 10.37; 26.7% female). Four separate linear regression analyses were conducted to evaluate the relation between anxiety sensitivity, distress tolerance, and their interaction with each of the four smoking abstinence expectancies (i.e., somatic symptoms, positive consequences, harmful consequences, and negative mood).

RESULTS

Results indicated that higher anxiety sensitivity was related to higher somatic symptoms, harmful consequences, and negative mood abstinence expectancies, whereas distress tolerance was related to higher positive consequences. Further, anxiety sensitivity and distress tolerance interacted to confer greater expectancies for the positive consequences of quitting.

CONCLUSIONS

The current findings are among the first to document that anxiety sensitivity and distress tolerance are clinically relevant factors to consider when tailoring smoking cessation treatments for Black individuals who smoke. Future research is needed to examine distress tolerance and anxiety sensitivity as longitudinal predictors of smoking abstinence expectancies among Black individuals who smoke.

A Southern addiction evaluation project: investigating the impact of addiction through a survey HBSC based

Background

Adolescence is a critical phase of development characterized by numerous physical, psychological and social changes. During this stage, individuals may engage in experimentation and risky behavior, leading to increased vulnerability to addiction. This article aims to present the results of a survey based on the HBSC (Health Behavior in School-aged Children) surveillance model in a province of Southern Italy for primary and secondary school students.

Methods

We conducted a prospective study from March 2020 to April 2023 through the administration of a questionnaire to students of the healthcare faculties of the University of Messina and primary and secondary school students, composed of 19 items and based on HBSC surveillance.

Results

We collected a total of 664 questionnaires. We found that smoking habits increase with age: approximately 31% of secondary school students declare they are real smokers compared to 40% of HCP students. At least once, in the three study groups, students experienced alcohol consumption at different rates, with younger students having a greater propensity to drink than older students. Fortunately, in our sample, no middle school students had tried cannabis. At the same time there is a surprising decrease in gambling in all categories compared to national data.

Conclusions

The presence of addictive behaviors in our sample was found to be widespread despite being in line with the national trend. Furthermore, we have observed a reduction in recent years which needs to be investigated to assess the reasons. Primary prevention is probably the main weapon in the hands of politicians and must be applied early in school and community settings to reduce prevalence.

Development and evaluation of a polygenic risk score for lung cancer in never-smoking women: A large-scale prospective Chinese cohort study

The proportion of lung cancer in never smokers is rising, especially among Asian women, but there is no effective early detection tool. Here, we developed a polygenic risk score (PRS), which may help to identify the population with higher risk of lung cancer in never-smoking women. We first performed a large GWAS meta-analysis (8595 cases and 8275 controls) to systematically identify the susceptibility loci for lung cancer in never-smoking Asian women and then generated a PRS using GWAS datasets. Furthermore, we evaluated the utility and effectiveness of PRS in an independent Chinese prospective cohort comprising 55 266 individuals. The GWAS meta-analysis identified eight known loci and a novel locus (5q11.2) at the genome-wide statistical significance level of P < 5 × 10-8 . Based on the summary statistics of GWAS, we derived a polygenic risk score including 21 variants (PRS-21) for lung cancer in never-smoking women. Furthermore, PRS-21 had a hazard ratio (HR) per SD of 1.29 (95% CI = 1.18-1.41) in the prospective cohort. Compared with participants who had a low genetic risk, those with an intermediate (HR = 1.32, 95% CI: 1.00-1.72) and high (HR = 2.09, 95% CI: 1.56-2.80) genetic risk had a significantly higher risk of incident lung cancer. The addition of PRS-21 to the conventional risk model yielded a modest significant improvement in AUC (0.697 to 0.711) and net reclassification improvement (24.2%). The GWAS-derived PRS-21 significantly improves the risk stratification and prediction accuracy for incident lung cancer in never-smoking Asian women, demonstrating the potential for identification of high-risk individuals and early screening.

The role of interpersonal trauma and substance use in mental health: A large population-based study

Both interpersonal trauma (IPT) and substance use are linked to mental health problems, however their interplay is understudied. This study will investigate the relationship between IPT, substance use and mental health in a large population-based sample. Participants included 3756 individuals, mainly young university students using a snowball sampling method. History of IPT was collected retrospectively using the Traumatic Experiences Checklist. Substance use was examined using the World Health Organization's Alcohol, Smoking and Substance Involvement Screening Test. Mental health symptoms were assessed by the DSM-5 Level 1 Cross-Cutting Symptom Measure. Moderation analyses were performed investigating the relationship between IPT, substance use, and mental health symptoms. Participants exposed to IPT had a higher prevalence of substance use (cannabis, alcohol, tobacco) and had more severe mental health problems than people without IPT. Substance use was associated with a blunted increase of depression, anxiety, and anger in trauma victims. A history of abuse was more strongly linked to substance use than neglect. Moderation analyses further revealed that cannabis use increased psychotic symptoms and psychotic symptoms increased cannabis use in participants with high levels of IPT. Our findings indicate that substance use worsens psychotic symptoms in IPT victims whilst dampening other mental health symptoms.

Smoking Susceptibility and Trends Among Nonsmoking Adolescents: An International Study

OBJECTIVES

Smoking susceptibility is defined as a lack of firm decision against smoking, usually starts in the preparation and/or initiation stages of smoking behavior, and is a strong predictor of smoking experimentation during adolescence. However, the recent global prevalence and trends in smoking susceptibility among adolescents are not well documented. This study assessed global smoking susceptibility and secular trends among nonsmoking adolescents.

METHODS

Smoking susceptibility was analyzed using the most recent data from the Global Youth Tobacco Survey from 129 countries, where the data from each country were drawn from at least 1 survey conducted at any time between 1999 and 2020. Moreover, data from 82 countries were used to assess the average annual rate of change (AARC) in smoking susceptibility over time.

RESULTS

Smoking susceptibility among nonsmoking adolescents was 19.6%. A U-shaped relationship was observed between susceptibility and a country's economic level. Most countries showed no changes in susceptibility over time. Countries with a significant upward trend in susceptibility were primarily high-income and upper middle-income countries in the American region. At the World Health Organization regional level, susceptibility significantly decreased in the European region (AARC: -3.5%; 95% confidence interval, -5.8 to -0.8); however, it significantly increased in the American region (AARC: 2.2%; 95% confidence interval, 1.3-3.1).

CONCLUSIONS

Smoking susceptibility remains a serious public health challenge among adolescents worldwide. More public health policies are needed to reduce susceptibility and to control its upward trend in the American region and high-income countries.

Smoking, Drinking, and Dietary Risk Factors for Head and Neck Cancer in Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial Participants

Importance

There is a paucity of large-scale prospective studies evaluating the risk of developing head and neck cancer (HNC) associated with smoking, drinking, and dietary habits.

Objective

To determine the association of smoking, drinking, and dietary habits with the risk of developing HNC.

Design, Setting, and Participants

A nested cohort survival analysis of Prostate, Lung, Colorectal, and Ovarian (PLCO) Cancer Screening Trial participants was performed. Participants were between 55 and 74 years of age and recruited at 10 centers across the US from November 1993 to July 2001. Participants who developed HNC were matched with controls based on demographics and family history of HNC for analysis of smoking habits; for the analysis of drinking and dietary habits, matching was performed on smoking status and duration in addition to demographics and family history of HNC. Data analysis was performed from January to November 2023.

Exposures

Smoking, drinking, and dietary habits.

Main Outcome and Measure

Diagnosis of HNC.

Results

In total, 139 926 participants (51% female; mean [SD] age, 62.6 [5.4] years) were included in the analysis of smoking habits with a median (IQR) follow-up time of 12.1 (10.3-13.6) years, 571 of whom developed HNC. HNC risk associated with smoking increased the closer the proximity of the head and neck subsite to the lungs, with the greatest risk associated with smoking observed in laryngeal cancer (current smoker hazard ratio [HR], 9.36; 95% CI, 5.78-15.15 compared to a nonsmoker). For analysis of drinking and dietary habits, 94 466 participants were included in the analysis of smoking habits with a median (IQR) follow-up time of 12.2 (10.5-13.6) years, 264 of whom developed HNC. HNC risk increased with heavy drinking (HR, 1.85; 95% CI, 1.44-2.38) and decreased with consumption of whole grains (HR, 0.78; 95% CI, 0.64-0.94/oz per day), whole fruits (HR, 0.90; 95% CI, 0.82-0.98/cup per day), and overall healthy eating, as scored by Healthy Eating Index 2015 (HR, 0.87; 95% CI, 0.78-0.98/10 points).

Conclusions and Relevance

In this nested cohort study, the risk of HNC associated with smoking was higher for subsites that were closer to the lungs; heavy drinking was associated with greater HNC risk, while healthy eating was associated with a modest reduction in HNC risk.

[Perioperative smoking cessation (conventional smoking and e-cigarettes) in 2023. A narrative review of the literature]

INTRODUCTION

Tobacco addiction is the leading cause of preventable death. During the perioperative period, patients who smoke are at increased risk of systemic as well as surgical site complications.

STATE OF THE ART

Surgery is an ideal time for change of lifestyle habits. It is vital to seize this opportunity to improve the patient's health in the long- as well as the short-term. Smoking cessation should be encouraged in all surgical patients. Initiating smoking cessation combines pharmacological treatment and a behavioral approach. In this field, significant advances have been recorded over the last decade. This review proposes a practical approach that every practitioner will be able to apply.

PERSPECTIVES

In this review, we will also examine ongoing research, particularly as regards vaccination and the place of biomarkers.

CONCLUSIONS

Smoking represents a major source of health-related complications. Smoking cessation must therefore remain a priority in the management of medical and surgical patients.

Sex- and Age-Specific Differences in Risk Profiles and Early Outcomes in Adults With Acute Coronary Syndromes

BACKGROUND

Adults <55 years of age comprise a quarter of all acute coronary syndromes (ACS) hospitalisations. There is a paucity of data characterising this group, particularly sex differences. This study aimed to compare the clinical and risk profile of patients with ACS aged <55 years with older counterparts, and measure short-term outcomes by age and sex.

METHOD

The study population comprised patients with ACS enrolled in the AUS-Global Registry of Acute Coronary Events (GRACE), Cooperative National Registry of Acute Coronary Syndrome Care (CONCORDANCE) and SNAPSHOT ACS registries. We compared clinical features and combinations of major modifiable risk factors (hypertension, smoking, dyslipidaemia, and diabetes) by sex and age group (20-54, 55-74, 75-94 years). All-cause mortality and major adverse events were identified in-hospital and at 6-months.

RESULTS

There were 16,658 patients included (22.3% aged 20-54 years). Among them, 20-54 year olds had the highest proportion of ST-elevation myocardial infarction compared with sex-matched older age groups. Half of 20-54 year olds were current smokers, compared with a quarter of 55-74 year olds, and had the highest prevalence of no major modifiable risk factors (14.2% women, 12.7% men) and of single risk factors (27.6% women, 29.0% men), driven by smoking. Conversely, this age group had the highest proportion of all four modifiable risk factors (6.6% women, 4.7% men). Mortality at 6 months in 20-54 year olds was similar between men (2.3%) and women (1.7%), although lower than in older age groups.

CONCLUSIONS

Younger adults with ACS are more likely to have either no risk factor, a single risk factor, or all four modifiable risk factors, than older patients. Targeted risk factor prevention and management is warranted in this age group.

Association of cigarette excise taxes and clean indoor air laws with change in smoking behavior in the United States: a Markov modeling analysis

The rates of cigarette smoking in the United States have declined over the past few decades in parallel with increases in cigarette taxes and introduction of more stringent clean indoor air laws. Few longitudinal studies have examined association of taxes and clean indoor air policies with change in smoking nationally. This study examined the association of state and local cigarette taxes and clean indoor laws with change in smoking status of 18,499 adult participants of the longitudinal 2010-2011 Tobacco Use Supplement of the Current Population Survey over a period of 1 year. Every $1 increase in cigarette excise taxes was associated with 36% higher likelihood of stopping smoking among regular smokers. We found no association between clean indoor air laws and smoking cessation nor between taxes and clean indoor air laws with lower risk of smoking initiation. Cigarette taxes appear to be effective anti-smoking policies. Some state and local governments do not take full advantage of this effective policy measure.

Trends in Smoking Before, During, and After Pregnancy in the United States from 2000 to 2020: Pregnancy Risk Assessment Monitoring System

Objectives: This study used 2000-2020 Pregnancy Risk Assessment Monitoring System data to estimate trends in smoking before, during, and after pregnancy, as well as quitting smoking during pregnancy. Materials and Methods: Weighted prevalence and 95% confidence intervals (CIs) were calculated by year for each smoking-related measure. Annual percent change (APC) and average annual percent change (AAPC) in prevalence were estimated using Joinpoint regression to characterize trends over time. Results: Between 2000 and 2020, significant decreases in the prevalence of smoking before (23.0% to 14.0%; AAPC = -2.3% [95% CI = -2.9% to -1.7%]), during (13.2% to 6.5%; AAPC = -3.4% [95% CI = -4.0% to -2.7%]), and after pregnancy (18.9% to 8.8%; AAPC = -3.6% [95% CI = -4.3% to -2.9%]) were observed. For each measure, the fastest declines occurred largely throughout the 2010s (before: APC = -5.5% [2012-2020]; during: APC = -5.1% [2009-2020]; and after: APC = -6.4% [2012-2020]). The proportion of people who quit smoking during pregnancy significantly increased from 43.2% in 2000 to 53.7% in 2020 (AAPC = 1.0%; 95% CI = 0.2%-1.9%); however, Joinpoint regression detected relatively no change in quitting during pregnancy between 2010 and 2020 (APC = 0.0%; 95% CI = -0.4% to 0.5%). Conclusions: The prevalence of smoking before, during, and after pregnancy has reduced dramatically in the United States between 2000 and 2020, with the fastest declines occurring throughout the second decade of the twenty-first century. However, prevention and cessation efforts are still needed since approximately half of people who smoked before pregnancy continue to smoke during pregnancy.

Inequality in smoking and related risk factors for smoking in expectant mothers - a nationwide Danish register-based study

AIMS

Foetuses exposed to smoking during pregnancy are disadvantaged due to numerous adverse obstetric outcomes. This study aimed to examine 1) inequality in maternal smoking between subgroups of pregnant women and 2) significant risk factors of maternal smoking.

METHODS

Data were collected from Danish registries. Trends in maternal smoking within each study period, T1 (2000-2002) and T2 (2014-2016), were investigated by Poisson regression calculating prevalence proportion ratios, and trends between study periods were studied by adding an interaction term. The significance of risk factors for maternal smoking (low age, low education, living alone and having a moderate/severe mental health condition) were studied by interaction analysis on the additive scale.

RESULTS

The prevalence of maternal smoking decreased from 21% in 2000 to 7% in 2016. Decreases were found in all subgroups of maternal age, cohabitation status, educational level and mental health condition. However, large differences in smoking prevalence between subgroups were found, and inequality in maternal smoking increased from 2000 to 2016. The probability of maternal smoking increased with the addition of risk factors, and positive additive interactions were found for almost all combinations of multiple risk factors.

CONCLUSIONS

Our results provide knowledge on risk factors and increasing levels of inequality in maternal smoking which points to a need for targeted interventions in relation to maternal smoking for subgroups of pregnant women in future smoking cessation programmes and in antenatal care.

Mortality burden and future projections of major risk factors for esophageal cancer in China from 1990 to 2019

OBJECTIVE

This study, based on Global Burden of Disease (GBD) data, aimed to report the long-term trend in mortality rates caused by risk factors for esophageal cancer (EC) in China from 1990 to 2019 and predict the burden of EC mortality caused by these risk factors over the next 15 years.

METHODS

We examined six risk factors that influenced EC mortality rates in China and their respective rankings. Furthermore, we analyzed the number of deaths and crude mortality rates (CMR) caused by these risk factors for both sexes and different age groups. Age-standardized mortality rates (ASMR) and the number of deaths across all age groups were also analyzed. Finally, we utilized the Bayesian Age-Period-Cohort (BAPC) model to predict the trends in ASMR burden caused by these risk factors in the future.

RESULTS

From 1990 to 2019, the percentage changes in ASMR for EC caused by the six risk factors in China were as follows: smoking (- 33.4%), alcohol consumption (- 23.0%), low fruit intake (- 73.6%), low vegetable intake (- 96.0%), high Body Mass Index (BMI) (25.1%), and tobacco chewing (- 32.8%). In 2019, the top three risk factors contributing to EC ASMR in China were smoking, alcohol consumption, and high BMI. Overall, the ASMR for EC in China fluctuated and declined from 1990 to 2019. The most common risk factors for males were smoking and alcohol consumption, while low fruit intake and high BMI were the most common risk factors for females. The impact of these risk factors on EC mortality increased with age, except for the elderly population. BAPC analysis indicated that the influence of these risk factors on ASMR was expected to remain relatively stable in the next 15 years, suggesting a continued significant burden of EC.

CONCLUSION

The projected burden of EC mortality in China was expected to continue increasing steadily over the next 15 years, highlighting the pressing need for disease control measures. To alleviate this burden, targeted prevention and control policies addressing risk factors for EC such as smoking, alcohol consumption, and high BMI are necessary.

Associations between body mass index and smoking behaviour: A cross-sectional study of the German adult population

BACKGROUND

Both smoking and high body weight are risk factors for disease, hence, the association between smoking and body weight is an important health issue. Furthermore, concern about weight gain after quitting smoking is for many smokers a barrier to smoking cessation. The present study aims to explore the association between body mass index (BMI) and current tobacco smoking status in the population of Germany, and smoking and quitting behaviour amongst smokers (and recent ex-smokers =<12 months since quitting).

METHODS

Cross-sectional analysis of two waves of data collected from March through June 2021 through a representative face-to-face household survey in Germany (N = 3 997 respondents aged ≥18). The associations between smoking and quitting behaviours and BMI were analysed through four regression models adjusted for socio-demographic, socio-economic, and smoking characteristics of respondents.

RESULTS

Long-term ex-smokers (>= 12 months since quitting smoking) were more likely to have a higher BMI compared to never smokers (β = 0.64, 95% confidence interval (CI) = 0.10-1.19). There was no statistically significant association between current smoking status or recent ex-smoking status and BMI (β = -0.29,95 %CI = -0.75-0.17 and β = -0.53, 95 %CI = -2.45-1.40). Among current smokers, no statistically significant association was found between BMI and the motivation to stop smoking (OR = 1.01, 95 %CI = 0.99-1.03). Neither number of cigarettes smoked a day nor outcome of most recent quit attempt were related to BMI (β = 0.01, 95 %CI = -0.04-0.05 and OR = 0.41, 95 %CI = 0.05-3.05).

CONCLUSION

In the German population long-term ex-smoking but not current and recent ex-smoking was associated with increased BMI. Future research should further explore the association between smoking behaviour and abdominal obesity, preferably using a more accurate measure for abdominal obesity than BMI.

Participation in Australian drug treatment programs for individuals engaging in high-risk substance use: Data from a nationally representative sample

INTRODUCTION

Substance use, including drugs, alcohol and smoking have a significant health, social and economic impact. We aim to assess the rate and factors associated with treatment access among individuals with high-risk substance use.

METHOD

This study is a cross-sectional analysis of the 2019 Australian National Drug Strategy Household Survey (N = 22,015). Participants were persons with high-risk substance use based on the Alcohol, Smoking and Substance Involvement Screening Test-Lite (ASSIST-Lite) and current smokers. We measured self-reports of past 12-month engagement in a tobacco, alcohol or other drugs treatment program.

RESULTS

Overall, 0.4% had high-risk drug use (0.3% cannabis, 0.1% meth/amphetamine or 0.1% opioids), 7.4% had high-risk alcohol use, and 14.0% currently smoked. Among high-risk users, past 12-month treatment access rates were 50.6% [22.3-78.9%] for opioids, 27.1% [8.1-46.1%] for meth/amphetamine, 14.5% [4.3-24.7%] for cannabis, 9.6% [8.1-11.0%] for alcohol and 11.7% [10.6-12.9%] for current smoking. The primary source of treatment support was information and education (12.7% drugs, 4.6% alcohol, 4.0% smoking), followed by counselling (6.7% drugs, 4.5% alcohol, 3.0% smoking). Online or internet support was accessed by 5.9% (drug) and 1.6% (alcohol) people with high-risk use. Psychological distress was associated with treatment access (drugs: odds ratio 3.03 [0.77-11.95], p = 0.111; alcohol: odds ratio 3.16 [2.20-4.56], p ≤ 0.001; smoking: odds ratio 1.95 [1.52-2.49], p ≤ 0.001).

DISCUSSION AND CONCLUSIONS

The proportion of people engaging in risky substance use who had used treatment programs remains low, especially for alcohol. Public health strategies to scale up treatment access are warranted.

The global magnitude and temporal trend of rheumatoid arthritis burden attributable to smoking from 1990 to 2019

OBJECTIVES

The relationship between smoking and RA has been confirmed. Most nations have ratified the Framework Convention on Tobacco Control. However, there are considerable regional differences in how effectively tobacco control measures were implemented. This study was carried out to estimate the spatiotemporal trends of smoking-related RA burdens.

METHODS

Data were available from the Global Burden of Disease Study 2019 and were analysed by age, sex, year and region. Joinpoint regression analysis was applied to the analysis of temporal trends in the RA burden resulting from smoking over 30 years.

RESULTS

From 1990 to 2019, the number of global RA cases increased each year. The age-standardized prevalence, death and disability-adjusted life-year (DALY) rates also increased. However, there was a wave in the changing trend of the age-standardized death rate, with the lowest point in 2012 and the highest point in 1990. Smoking, in particular, was responsible for 11.9% of total RA deaths and 12.8% of total DALYs in 1990 but only 8.5% of total RA deaths and 9.6% of total DALYs in 2019. A greater burden from smoking exposure was borne by men, older adults and people living in high-middle and high sociodemographic index (SDI) countries and regions. Moreover, the UK demonstrated the highest reduction in age-standardized death and DALY rates over the three decades.

CONCLUSION

There were reductions in the age-standardized burdens of RA caused by smoking worldwide. Nevertheless, this continues to be an issue in some areas, and efforts to reduce smoking should be made to lessen this growing burden.

Cost-Effectiveness of a Comprehensive Primary Care Smoking Treatment Program

INTRODUCTION

Smoking is the leading preventable cause of death and disease in the U.S. This study evaluates the cost-effectiveness from a healthcare system perspective of a comprehensive primary care intervention to reduce smoking rates.

METHODS

This pragmatic trial implemented electronic health record prompts during primary care visits and employed certified tobacco cessation specialists to offer proactive outreach and smoking cessation treatment to patients who smoke. The data, analyzed in 2022, included 10,683 patients in the smoking registry from 2017 to 2020. Pre-post analyses compared intervention costs to treatment engagement, successful self-reported smoking cessation, and acute health care utilization (urgent care, emergency department visits, and inpatient hospitalization). Cost per quality-adjusted life year was determined by applying conversion factors obtained from the tobacco research literature to the cost per patient who quit smoking.

RESULTS

Tobacco cessation outreach, medication, and counseling costs increased from $2.64 to $6.44 per patient per month, for a total post-implementation intervention cost of $500,216. Smoking cessation rates increased from 1.3% pre-implementation to 8.7% post-implementation, for an incremental effectiveness of 7.4%. The incremental cost-effectiveness ratio was $628 (95% CI: $568, $695) per person who quit smoking, and $905 (95% CI: $822, $1,001) per quality-adjusted life year gained. Acute health care costs decreased by an average of $42 (95% CI: -$59, $145) per patient per month for patients in the smoking registry.

CONCLUSIONS

Implementation of a comprehensive and proactive smoking cessation outreach and treatment program for adult primary care patients who smoke meets typical cost-effectiveness thresholds for healthcare.

Dental caries, oral hygiene status and deleterious habits among migrant construction workers of Belagavi, India

Background

Occupation significantly influences oral health, with factors like the work environment, stress levels, access to dental care, and job-related habits playing crucial roles. The oral health of construction workers, especially migrant workers, is a noteworthy concern. Understanding the oral health of this population is crucial for enhancing their quality of life through various means. This study aimed to investigate the prevalence of dental caries, oral hygiene status, and deleterious habits in this occupational group of Belagavi district, Karnataka.

Materials and methods

Study design was cross-sectional in nature. Before commencement of the study a pilot study was conducted. Multi-stage random sampling technique was employed, and 610 participants were recruited for the study. Trained and calibrated examiners recorded WHO dentition status and treatment needs (2013) and Oral Hygiene Index Simplified (OHI-S). Collected data was analyzed using descriptive analysis, chi-square, one-way ANOVA, and multiple linear regression analysis.

Results

The prevalence of dental caries among construction workers was significantly high (81%), and poor oral hygiene was observed among 36.9% of them. The prevalence of smoking, the tobacco chewing habit, and alcohol consumption among the construction workers was found to be 21.6%, 59.9%, and 37.3%, respectively. The dependence of OHI-S and DMFT on predictors (age, gender and deleterious habits) was found to be 21.5% and 39.6%, respectively.

Conclusions

Migrant construction workers in Belagavi had a high caries prevalence, poor oral hygiene status, and a high prevalence of deleterious habits such as tobacco use. These results emphasize the necessity of awareness and dental health education programs to improve the oral health of construction workers.

Longitudinal association between e-cigarette use and respiratory symptoms among US adults: Findings from the Population Assessment of Tobacco and Health Study Waves 4-5

BACKGROUND

We assessed longitudinal effects of e-cigarette use on respiratory symptoms in a nationally representative sample of US adults by combustible tobacco smoking status.

METHODS

We analyzed Waves 4-5 public-use data from the Population Assessment of Tobacco and Health Study. Study sample included adult respondents who reported no diagnosis of respiratory diseases at Wave 4, and completed Waves 4-5 surveys with no missing data on analytic variables (N = 15,291). Outcome was a validated index of functionally important respiratory symptoms based on 7 wheezing/cough questions (range 0-9). An index score of ≥2 was defined as having important respiratory symptoms. Weighted lagged logistic regression models were performed to examine the association between e-cigarette use status at Wave 4 (former/current vs. never use) and important respiratory symptoms at Wave 5 by combustible tobacco smoking status (i.e., never/former/current smokers), adjusting for Wave 4 respiratory symptom index, sociodemographic characteristics, secondhand smoke exposure, body mass index, and chronic disease.

RESULTS

Among current combustible tobacco smokers, e-cigarette use was associated with increased odds of reporting important respiratory symptoms (former e-cigarette use: adjusted odds ratio [AOR] = 1.39, 95% confidence interval [CI]: 1.07-1.81; current e-cigarette use: AOR = 1.55, 95% CI: 1.17-2.06). Among former combustible tobacco smokers, former e-cigarette use (AOR = 1.51, 95% CI: 1.06-2.15)-but not current e-cigarette use (AOR = 1.59, 95% CI: 0.91-2.78)-was associated with increased odds of important respiratory symptoms. Among never combustible tobacco smokers, no significant association was detected between e-cigarette use and important respiratory symptoms (former e-cigarette use: AOR = 1.62, 95% CI: 0.76-3.46; current e-cigarette use: AOR = 0.82, 95% CI: 0.27-2.56).

CONCLUSIONS

The association between e-cigarette use and respiratory symptoms varied by combustible tobacco smoking status. Current combustible tobacco smokers who use e-cigarettes have an elevated risk of respiratory impairments.

Medical Trainees' Knowledge and Attitudes Towards Electronic Cigarettes and Hookah: A Multinational Survey Study

BACKGROUND

The rising prevalence of electronic cigarette (e-cigarette) and hookah use among youth raises questions about medical trainees' views of these products. We aimed to investigate medical trainees' knowledge and attitudes toward e-cigarette and hookah use.

METHODS

We used data from a large cross-sectional survey of medical trainees in Brazil, the United States, and India. We investigated demographic and mental health aspects, history of e-cigarettes and tobacco use, knowledge and attitudes toward e-cigarettes and hookah, and sources of information on e-cigarettes and hookah. Although all medical trainees were eligible for the original study, only senior students and physicians-in-training were included in the present analysis.

RESULTS

Of 2,036 senior students and physicians-in-training, 27.4% believed e-cigarette use to be less harmful than tobacco smoking. As for hookah use, 14.9% believed it posed a lower risk than cigarettes. More than a third of trainees did not acknowledge the risks of passive e-cigarette use (42.9%) or hookah smoking (35.1%). Also, 32.4% endorsed e-cigarettes to quit smoking, whereas 22.5% felt ill equipped to discuss these tobacco products with patients. Fewer than half recalled attending lectures on these topics, and their most common sources of information were social media (54.5%), Google (40.8%), and friends and relatives (40.3%).

CONCLUSIONS

Medical trainees often reported incorrect or biased perceptions of e-cigarettes and hookah, resorted to unreliable sources of information, and lacked the confidence to discuss the topic with patients. An expanded curriculum emphasis on e-cigarette and hookah use might be necessary because failing to address these educational gaps could risk years of efforts against smoking normalization.

Tobacco use and behaviour among South African adolescents and young adults: systematic review and meta-analysis

OBJECTIVE

Tobacco use, particularly the initiation of smoking during adolescence and young adulthood, represents a significant public health concern in South Africa. This study aims to conduct a comprehensive review of published literature about tobacco use and behaviour among adolescents and young adults and to determine an aggregated prevalence estimate of tobacco use within this demographic.

DESIGN

Systematic review and meta-analysis.

DATA SOURCES

PubMed/MEDLINE, EMBASE, Cochrane Library, Scopus and Google Scholar were searched from 1 January 2000 through 31 October 2023.

ELIGIBILITY CRITERIA

Studies were eligible for inclusion if they were cross-sectional studies conducted in South Africa and measured the prevalence and determinants of tobacco use among adolescents and young adults aged 12-24 years.

DATA EXTRACTION AND SYNTHESIS

Two reviewers independently extracted information for each article and saved it into an Excel spreadsheet. Risk of bias analysis was conducted using the Risk of Bias Assessment Tool for non-randomised studies. The methodology quality of each selected study was evaluated using the Joanna Briggs Institute checklist. The heterogeneity of prevalence estimates was assessed using I2 statistic (random-effects DerSimonian-Laid approach).

RESULTS

Out of 73 articles identified, 12 articles were included in the analysis. The pooled prevalence of current tobacco use among South African adolescents and young adults was estimated to be 22%. The pooled prevalence of tobacco use among school dropouts, university students and secondary school learners was 51%, 20% and 16%, respectively. Stratifying using gender, boys (26%) were two times more likely to use tobacco than girls (13%).

CONCLUSION

The elevated occurrence of tobacco usage among South African adolescents and young adults is a relevant public health concern. There is a need for more population-based prevalence studies at a national level to estimate the burden of tobacco use in South Africa.

A literature review of a meta-analysis of BRAF mutations in non-small cell lung cancer

BACKGROUND

The research on the relationship between the Braf Proto-oncogene (BRAF) mutation and lung cancer has generated conflicting findings. Nevertheless, there is an argument suggesting that assessing the BRAF status could offer benefits in terms of managing and prognosing individuals with non-small cell lung cancer (NSCLC). To present a comprehensive overview of this subject, we undertook an up-to-date meta-analysis of pertinent publications.

METHODS

We conducted an extensive literature search utilizing Medical Subject Headings keywords, namely "BRAF", "mutation", "lung", "tumor", "NSCLC", and "neoplasm", across multiple databases, including PubMed, EMBASE, ISI Science Citation Index, and CNKI. For each study, we calculated and evaluated the odds ratio and confidence interval, focusing on the consistency of the eligible research.

RESULTS

The meta-analysis unveiled a noteworthy correlation between BRAF mutation and lung cancer. No significant evidence was found regarding the connection between smoking and staging among individuals with BRAF mutations. Furthermore, a substantial disparity in the rate of BRAF mutations was observed between males and females.

CONCLUSION

Our meta-analysis revealed a significant correlation between BRAF mutations and NSCLC. Moreover, we observed a higher incidence of BRAF lung mutations in females compared to males. Additionally, the BRAFV600E mutation was found to be more prevalent among female patients and nonsmokers.

A decade of tobacco control efforts: Implications for tobacco smoking prevalence in Eastern Mediterranean countries

BACKGROUND AND OBJECTIVES

This study aimed to assess the association between the 10-year implementation of tobacco control policies, cigarette affordability index and changes in tobacco smoking prevalence across Eastern Mediterranean (EMR) countries.

MATERIALS AND METHODS

An ecologic study was conducted using EMR countries as the analytical unit. Data from three sources were utilized: the MPOWER scale to measure tobacco control policy implementation (2010-2020), the tobacco affordability index (expressed as a percentage of GDP per capita required to purchase 2000 cigarettes, from 2010 to 2020), and national tobacco smoking prevalence data for EMR countries (2010-2023). Linear Fixed-effect regression was employed to investigate associations between changes in MPOWER scores, the cigarette affordability index, and alterations in tobacco prevalence over a decade.

RESULTS

Statistically significant inverse associations were observed between changes in MPOWER scores and tobacco smoking prevalence among both men and women in EMR countries (P-value<0.05). Each unit increase in MPOWER score corresponded to a 0.26% reduction in tobacco prevalence among men and a 0.12% reduction among women. The regression model revealed that each unit increase in the cigarette affordability index was linked to a 0.9% decrease in tobacco smoking prevalence across EMR countries (P-value<0.05). Furthermore, even after adjusting for multiple confounders, significant inverse associations were noted between tobacco monitoring (β = -0.41), health warning (β = -0.45), and changes in tobacco smoking prevalence (P-value<0.05).

CONCLUSION

This study underscored the effectiveness of enhancing the implementation of tobacco control policies and increasing the cigarette affordability index as preventive measures to reduce tobacco smoking prevalence in EMR countries over the past decade.

Study of waterpipe smoking topography in Fars province of Iran

Despite a sharp increase in the use of the waterpipe (WP) has been noted recently in Iran, no information is available for the smoking behavior and topography parameters. The present study is intended to obtain the inhalation and smoking topography parameters for the Iranian WP smokers. The smoking data collected from 122 smoking sessions, including 192 WP smokers in the Iranian Fars province have been used to perform smoking topography assessments. The influence of demographic and smoking parameters on puffing data is obtained. Results have indicated that gender and tobacco type strongly affect puff volume and duration. Women smokers inhale smaller volume of smoke than men and puff duration is significantly increased for regular smokers than occasional smokers. However, the results of the present study have not revealed a major effect of age, residence and setting on the puffing behavior.

Interaction between hepatitis B, hepatitis C and smoking in the development of hepatocellular carcinoma: a systematic review and meta-analysis

BACKGROUND

This meta-analysis reports the relationship between hepatitis B virus (HBV), hepatitis C virus (HCV), smoking and their combined impact on the development of hepatocellular carcinoma (HCC).

METHODS

We conducted a systematic search of PubMed, Web of Science and Scopus databases up to 15 July 2023. Observational studies investigating the association between HBV, HCV and smoking in the development of HCC were included. We assessed between-study heterogeneity using the I2 statistics. The effect sizes were estimated as odds ratio (OR) with 95% confidence intervals (CIs) using a random-effects model.

RESULTS

Out of 20 794 studies identified in the initial search, 32 observational studies involving 22 282 participants met the inclusion criteria. Our meta-analysis showed that the combined impact of HBV and smoking was associated with an OR of 19.81 (95% CI: 14.77, 26.58), HCV and smoking was associated with an OR of 24.86 (95% CI: 12.41, 49.79), and coinfection of HBV and HCV was associated with an OR of 32.58 (95% CI: 20.57, 51.60).

CONCLUSIONS

Our findings indicate a significant interaction between HBV, HCV and smoking in the development of HCC and highlight the importance of addressing smoking cessation and viral hepatitis prevention and treatment as potential strategies for reducing HCC.

What impact would tobacco retailer proximity limit have on tobacco availability in New Zealand?

INTRODUCTION

One policy option to reduce the density of tobacco retailers is to restrict the distance retailers can be located to each other. This study examined the impacts of proximity limits of 150 m, 300 m and 450 m between tobacco retailers in New Zealand and if critical threshold reduction in tobacco retailers of 90%-95% would be achieved.

METHODS

Using a spatial modelling approach, tobacco retailers were randomly removed based on a minimum distance between retailers until there were zero retailers within each scenario's minimum distance. This was repeated for all three proximity limit scenarios and descriptive statistics are provided for each.

RESULTS

Implementation of 150 m, 300 m or 450 m distance restrictions between tobacco retailers would result in an average reduction in availability of 35%, 49% and 58%, respectively. On average, the current median distance to the closest retailer increases from 110 m to 377 m, to 568 m or to 718 m, respectively. The average median distance from a retailer to the closest school also increases across the three proximity limits, from 1017 m to 1087 m, to 1149 m or to 1231 m, respectively. Reduced clustering in deprived areas would be most apparent if a 450 m restriction policy was implemented.

CONCLUSIONS

A proximity limit of 450 m would reduce retailers by 58%, but would not reach proposed critical behaviour-change threshold of 90%-95% required to reduce smoking prevalence independently. There is a need for a combination of policies, which focus on promoting equity, to achieve this bold endgame goal.

Impact of electronic cigarette and heated tobacco product on conventional smoking: an Italian prospective cohort study conducted during the COVID-19 pandemic

OBJECTIVE

Debate continues about whether electronic cigarettes (e-cigarettes) and heated tobacco products (HTP) reduce or increase the probability of smoking, with many studies compromised by stated or unstated conflicts of interest. We undertook a longitudinal study in Italy.

METHODS

3185 Italian participants aged 18-74 years provided baseline (April-May) and follow-up (November-December) responses in 2020, reporting smoking status and use of e-cigarettes and HTP. We tracked transitions over that period and reported risk ratios (RR) and corresponding 95% CIs for changes in smoking in relation to baseline use of e-cigarettes and HTPs.

RESULTS

Never cigarette smokers who used e-cigarettes at baseline were much more likely to start smoking (compared with never users, RR 8.78; 95% CI: 5.65 to 13.65) and current HTP users (RR 5.80; 95% CI: 3.65 to 9.20). Among ex-smokers, relapse (17.2%) at follow-up was more likely among e-cigarette (RR 4.25; 95% CI: 2.40 to 7.52) and HTP users (RR 3.32; 95% CI: 2.05 to 5.37). Among current smokers at baseline, those who had continued smoking at follow-up were 85.4% overall. These were more frequently current novel product users (compared with non-users, RR 1.10; 95% CI: 1.02 to 1.19 for e-cigarette users; RR 1.17; 95% CI: 1.10 to 1.23 for HTP users).

CONCLUSIONS

Both e-cigarette and HTP use predict starting smoking and relapse, and appear to reduce smoking cessation. Due to the limited sample size within specific strata, the association with quitting smoking should be confirmed by larger prospective studies. These findings do not support the use of e-cigarettes and HTPs in tobacco control as a consumer product, at least in Italy.

A novel technique to study the solutions of time fractional nonlinear smoking epidemic model

The primary goal of the current work is to use a novel technique known as the natural transform decomposition method to approximate an analytical solution for the fractional smoking epidemic model. In the proposed method, fractional derivatives are considered in the Caputo, Caputo-Fabrizio, and Atangana-Baleanu-Caputo senses. An epidemic model is proposed to explain the dynamics of drug use among adults. Smoking is a serious issue everywhere in the world. Notwithstanding the overwhelming evidence against smoking, it is nonetheless a harmful habit that is widespread and accepted in society. The considered nonlinear mathematical model has been successfully used to explain how smoking has changed among people and its effects on public health in a community. The two states of being endemic and disease-free, which are when the disease dies out or persists in a population, have been compared using sensitivity analysis. The proposed technique has been used to solve the model, which consists of five compartmental agents representing various smokers identified, such as potential smokers V, occasional smokers G, smokers T, temporarily quitters O, and permanently quitters W. The results of the suggested method are contrasted with those of existing numerical methods. Finally, some numerical findings that illustrate the tables and figures are shown. The outcomes show that the proposed method is efficient and effective.

The smoking population is not hardening in South Korea: a study using the Korea Community Health Survey from 2010 to 2018

INTRODUCTION

The hardening hypothesis proposes that the proportion of hardcore smokers increases when smoking prevalence declines. To evaluate whether such hardening occurs in South Korea, we examined the association between quitting behaviours, the number of cigarettes smoked per day and the proportion of hardcore smokers and smoking prevalence among local districts in South Korea.

METHODS

This study used the cross-sectional data from the Korea Community Health Survey (2010-2018) to examine local district-level associations between smoking prevalence and quit attempts, quit plans, quit ratios, cigarettes smoked per day and the proportion of hardcore smokers. Panel regression analysis was performed using the indicators of hardcore smoking (quit attempts, quit plans, quit ratios, cigarettes smoked per day and proportion of hardcore smokers) as the outcome variables, and prevalence of smoking, local districts, age and sex as predictor variables.

RESULTS

When the smoking prevalence of the districts decreased by 1%, quit attempts, quit plans and quit ratios increased by 0.24% (95% CI 0.11 to 0.37), 0.37% (95% CI 0.26 to 0.47) and 1.71% (95% CI 1.65 to 1.76), respectively. Cigarette consumption decreased by 0.17 cigarettes per day (95% 0.15 to 0.19), and the prevalence of hardcore smokers decreased by 0.88% (95% CI 0.78 to 0.98) when smoking prevalence decreased by 1%.

CONCLUSION

Hardening of smoking did not occur in South Korea when smoking prevalence declined, which suggests tobacco control policies in South Korea have been effective in reducing smoking prevalence without increasing the proportion of hardcore smokers.

Major Depressive Disorder Impacts Peripheral Artery Disease Risk Through Intermediary Risk Factors

BACKGROUND

Major depressive disorder (MDD) has been identified as a causal risk factor for multiple forms of cardiovascular disease. Although observational evidence has linked MDD to peripheral artery disease (PAD), causal evidence of this relationship is lacking.

METHODS AND RESULTS

Inverse variance weighted 2-sample Mendelian randomization was used to test the association the between genetic liability for MDD and genetic liability for PAD. Genetic liability for MDD was associated with increased genetic liability for PAD (odds ratio [OR], 1.17 [95% CI, 1.06-1.29]; P=2.6×10-3). Genetic liability for MDD was also associated with increased genetically determined lifetime smoking (β=0.11 [95% CI, 0.078-0.14]; P=1.2×10-12), decreased alcohol intake (β=-0.078 [95% CI, -0.15 to 0]; P=0.043), and increased body mass index (β=0.10 [95% CI, 0.02-0.19]; P=1.8×10-2), which in turn were associated with genetic liability for PAD (smoking: OR, 2.81 [95% CI, 2.28-3.47], P=9.8×10-22; alcohol: OR, 0.77 [95% CI, 0.66-0.88]; P=1.8×10-4; body mass index: OR, 1.61 [95% CI, 1.52-1.7]; P=1.3×10-57). Controlling for lifetime smoking index, alcohol intake, and body mass index with multivariable Mendelian randomization completely attenuated the association between genetic liability for MDD with genetic liability for PAD.

CONCLUSIONS

This work provides evidence for a possible causal association between MDD and PAD that is dependent on intermediate risk factors, adding to the growing body of evidence suggesting that effective management and treatment of cardiovascular diseases may require a composite of physical and mental health interventions.

Who smokes in Australia? Cross-sectional analysis of Australian Bureau of Statistics survey data, 2017-19

OBJECTIVES

To assess the socio-demographic and health-related characteristics of people who smoke daily, people who formerly smoked, and people who have never smoked in Australia.

STUDY DESIGN

Cross-sectional analysis of Australian Bureau of Statistics (ABS) survey data.

SETTING, PARTICIPANTS

Adult participants (16 370 people aged 18 years or older) in the ABS 2017-18 National Health Survey (NHS); adult participants in the ABS 2018-19 National Aboriginal and Torres Strait Islander Health Survey (NATSIHS) (6423 people aged 18 years or older).

MAIN OUTCOME MEASURES

Socio-demographic and health-related characteristics of people who smoke daily, people who formerly smoked, and people who have never smoked, expressed as population-weighted proportions, overall and by Indigeneity.

RESULTS

Among adult NHS respondents, an estimated 58.8% of people who smoked daily (95% confidence interval [CI], 56.2-61.4%) were men, 61.3% (95% CI, 58.7-63.9%) were 25-54 years old, 72.5% (95% CI, 70.0-74.8%) were born in Australia, and 65.4% (95% CI, 62.8-67.8%) lived in major cities and 54.3% (95% CI, 51.6-57.0%) in areas in the two socio-economically most disadvantaged quintiles; 75.9% (95% CI, 73.5-78.1%) reported good to excellent health, 73.0% (95% CI, 70.5-75.4%) reported low to moderate psychological distress, 69.0% of those aged 25-64 years (ie, of working age) had completed year 12 (high school), and 68.5% were currently employed. An estimated 2.57 million people smoke daily in Australia: 2.37 million non-Indigenous people (92%) and 195 700 Aboriginal or Torres Strait Islander people (8%).

CONCLUSIONS

While smoking is more frequent among people living in socio-economically disadvantaged areas and in certain population sub-groups, this first quantitative national profile indicates that most people who smoke daily are in paid employment, are non-Indigenous, are in good physical and mental health, and have completed year 12. Improved comprehensive structural supply- and demand-based tobacco control, informed by the needs of priority groups and the overall profile of people who smoke, is needed to reduce daily smoking prevalence among adults to the 2030 targets of 5% or less for all Australians and 27% or less for Aboriginal and Torres Strait Islander people.

The impact of smoking and alcohol consumption on rosacea: a multivariable Mendelian randomization study

Backgrounds

Observational studies have shown that cigarette smoking is inversely associated with risk of rosacea, However, it remains uncertain whether this association is causal or it is a result of reverse causation, and whether this association is affected by drinking behaviors.

Methods

This study utilized the summary-level data from the largest genome-wide association study (GWAS) for smoking, alcohol consumption, and rosacea. The objective was to investigate the effect of genetically predicted exposures to smoking and alcohol consumption on the risk of developing rosacea. Two-sample bidirectional Mendelian randomization (MR) was applied, accompanied by sensitive analyses to validate the robustness of findings. Furthermore, multivariable MR was conducted to evaluate the direct impact of smoking on rosacea.

Results

A decreased risk of rosacea was observed in individuals with genetically predicted lifetime smoking [odds ratio (OR)MR - IVW = 0.53; 95% confidence interval (CI), 0.318-0.897; P = 0.017], and number of cigarettes per day (ORMR - IVW = 0.55; 95% CI, 0.358-0.845; P = 0.006). However, no significant associations were found between initiation of regular smoking, smoking cessation, smoking initiation, alcohol consumption and rosacea. Reverse MR analysis did not show any associations between genetic liability toward rosacea and smoking or alcohol drinking. Importantly, the effect of lifetime smoking and the number of cigarettes per day on rosacea remained significant even after adjusting for alcohol consumption in multivariable MR analysis.

Conclusion

Smoking was causally related to a lower risk of rosacea, while alcohol consumption does not appear to be associated with risk of rosacea.

Gender equality and smoking among 15 to 25 year olds-a time-based ecological analysis of developments in Germany from 1960 to 2005

Introduction

Smoking is a major risk factor for premature death and health problems in which there are significant gender differences in the prevalence of smoking. This ecological study examines the correlation between changes in gender equality and prevalence of smoking among young adults (15-25 years old) in Germany over a period of 45 years (1960-2005).

Methods

Gender inequality was measured using the United Nations Gender Inequality Index (GII), which is composed of three dimensions; health, empowerment and labour market. It was calculated for the entire registered German population in five-year intervals with values between 0 and 1 (1 = highest inequality). The smoking prevalence of young women and men in Germany was established using a reconstruction method. A gender smoking ratio (GSR) with values between 0 and 1 was determined (1 = identical smoking prevalence among men and women). The smoking behaviour was illustrated and stratified by education. The correlation between the GII and the GSR was analysed.

Results

The GII decreased from 0.98 to 0.56 between 1960 and 2005. The GSR increased from 0.34 to 0.93. There was a strong negative correlation between the GII and the GSR (r = -0.71). The strength of the correlation fell slightly as the level of education decreased. An increase in gender equality as measured by the GII came along with similarities of smoking prevalence between young women and young men.

Conclusion

Successful tobacco prevention among young women and men may benefit from involving experts in gender-specific public health research to develop counter-advertising and gender-specific information as needed.

Immediate smoking cessation support during lung cancer screening: long-term outcomes from two randomised controlled trials

BACKGROUND

Immediate smoking cessation interventions delivered alongside targeted lung health checks (TLHCs) to screen for lung cancer increase self-reported abstinence at 3 months. The impact on longer term, objectively confirmed quit rates remains to be established.

METHODS

We followed up participants from two clinical trials in people aged 55-75 years who smoked and took part in a TLHC. These randomised participants in the TLHC by day of attendance to either usual care (UC) (signposting to smoking cessation services) or an offer of immediate smoking cessation support including pharmacotherapy. In the QuLIT1 trial, this was delivered face to face and in QuLIT2, it was delivered remotely. Follow-up was conducted 12 months after the TLHC by telephone interview with subsequent biochemical verification of smoking cessation using exhaled CO.

RESULTS

430 people were enrolled initially (115 in QuLIT1 and 315 in QuLIT2), with 4 deaths before 12 months leaving 426 (62.1±5.27 years old and 48% women) participants for analysis. At 12 months, those randomised to attend on smoking cessation support intervention days had higher quit rates compared with UC adjusted for age, gender, deprivation, and which trial they had been in; self-reported 7-day point prevalence (20.0% vs 12.8%; adjusted OR (AOR)=1.78; 95% CI 1.04 to 2.89) and CO-verified quits (12.1% vs 4.7%; AOR=2.97; 95% CI 1.38 to 6.90). Those in the intervention arm were also more likely to report having made a quit attempt (30.2% vs UC 18.5%; AOR 1.90; 95% CI 1.15 to 3.15).

CONCLUSION

Providing immediate smoking cessation support alongside TLHC increases long term, biochemically confirmed smoking abstinence.

Association between smoking and height loss in Japanese workers: A retrospective study

Height loss is reported to be an independent risk factor for all-cause and cardiovascular mortality. Smoking, which is responsible for a considerable proportion of deaths due to any cause, is also associated with lumbar disc degeneration, a major risk factor for height loss. Therefore, smoking could be an independent risk factor for height loss. To clarify the association between smoking status and height loss, a retrospective study with 8,984 (5,518 men and 3,466 women) Japanese workers was conducted. The present study population comprised 9,681 workers aged 40-74 years who participated in annual medical examinations between 2011 and 2017 (baseline). Subjects without a height measurement during 2012-2018 (endpoint) were excluded from the analysis (n = 697). Height loss was defined as being in the highest quartile of annul height decrease (1.48 mm/year for men and 1.79 mm/year for women). Independent of known cardiovascular risk factors, smoking was positively associated with height loss among men but not among women. With never smokers as the referent group, the adjusted odds ratio (95% confidence interval) was 1.15 (0.98, 1.35) for former smokers and 1.24 (1.05, 1.46) for current smokers among men, respectively. Among women, the corresponding values were 0.98 (0.79, 1.21) and 0.90 (0.71, 1.16), respectively. Since height loss and smoking are independent risk factors for all-cause and cardiovascular mortality, these results help clarify the mechanisms underlying the association between height loss and mortality risk.

The effects of smoking history on robotic transhiatal esophagectomy patient outcomes

Esophageal resection for the treatment of esophageal cancer generally entails high rates of morbidity and mortality. Patients with a smoking history have increased post-operative complications following esophagectomy. This study was undertaken to determine how smoking or a history of smoking can affect perioperative outcomes and morbidity following robotic transhiatal esophagectomy. 75 patients were prospectively followed and divided; 44 patients actively smoking or with a history of significant smoking were classified as 'smokers', while the other 31 patients were classified as 'non-smokers'. Significance was determined at a p-value of ≤ 0.05 and data are presented as median (mean ± SD). 'Smokers' averaged 70(70 ± 7.8) years, 89% male, with 82% undergoing neoadjuvant therapy. 'Nonsmokers' averaged 68(69 ± 7.8) years, 74% male, and 74% receiving neoadjuvant therapy. BMI and ASA class showed no significant difference between the cohorts. 'Smokers' had an operative time of 341(343 ± 91.0) minutes and a blood loss of 150(191 ± 140.0) mL; 'nonsmokers' had 291(298 ± 65.9) minutes and 100(140 ± 120.9) mL, respectively (p = 0.02 for operative time). Tumor size and AJCC staging were similar for both cohorts. No significant differences were noted in postoperative complications, Clavien-Dindo score ≥ III, in-hospital mortality, length of stay, or 30-day readmissions. Survival rates were comparable. Hospital costs for 'smokers' were $33,131(41,091 ± 23,465.17) and $34,896 (62,154 ± 65,839.53) for 'nonsmokers' (p = 0.05). Profit/loss was $-23,155 (- 15,137 ± 35,819.29) for smokers and $-23,720 (- 16,716 ± 50,864.64) for nonsmokers. Current or past 'smokers' had longer operative times and lower costs following robotic transhiatal esophagectomy, with no significant difference in postoperative complications or survival compared to 'non-smokers'.

Exploring gender disparities in the disease and economic tobacco-attributable burden in Latin America

Introduction

Tobacco use has significant health consequences in Latin America, and while studies have examined the overall impact, the gender-specific effects have not been thoroughly researched. Understanding these differences is crucial for effective tobacco control policies. The objective of this study was to explore the differences in tobacco-attributable disease and economic burden between men and women in Argentina, Brazil, Chile, Colombia, Costa Rica, Ecuador, Mexico, and Peru.

Methods

We used a previously validated economic model to quantify the impact of tobacco-related illnesses, including morbidity, mortality, healthcare costs, productivity losses, informal care expenses, and DALYs, by gender and age. We utilized data from national surveys, records, studies, and expert opinions to populate the model.

Results

In 2020, there were 351,000 smoking-attributable deaths. Men accounted for 69% and women 31%. Ecuador and Mexico had the highest male-to-female death ratio, while Peru and Chile had the smallest disparities. 2.3 million tobacco-related disease events occurred, with 65% in men and 35% in women. Ecuador and Mexico had higher disease rates among men, while Peru had a more balanced ratio. Regarding DALYs, men lost 6.3 million due to tobacco, while women lost 3.3 million, primarily from COPD, cardiovascular disease, and cancer. Brazil and Mexico had the highest DALY losses for both genders. Costa Rica had a lower male-to-female tobacco use prevalence ratio but ranked second in deaths, disease events, and DALYs attributed to tobacco. Colombia had a unique pattern with a male-to-female death ratio of 2.08 but a higher ratio for disease events. The health systems spent $22.8 billion to treat tobacco-attributable diseases, with a male-to-female cost ratio 2.15. Ecuador showed the greatest gender cost difference, while Peru had the lowest. Productivity loss due to tobacco was $16.2 billion, with Ecuador and Mexico exhibiting the highest gender disparities and Peru the lowest. Informal care costs amounted to $10.8 billion, with men incurring higher costs in Ecuador, Costa Rica, and Mexico.

Discussion

Tobacco causes significant health and economic burdens in Latin America, with gender-based differences. There is a need for gender-disaggregated data to improve tobacco control policies.

Smoking is associated with higher short-term risk of revision and mortality following primary hip or knee arthroplasty: a cohort study of 272,640 patients from the Dutch Arthroplasty Registry

BACKGROUND AND PURPOSE

Patients actively smoking at the time of primary hip or knee arthroplasty are at increased risk of direct perioperative complications. We investigated the association between smoking status and risk of revision and mortality within 2 years following hip or knee arthroplasty.

METHODS

We used prospectively collected data from the Dutch Arthroplasty Register. All primary total hip arthroplasties (THAs), total knee arthroplasties (TKAs), and unicondylar knee arthroplasties (UKAs) with > 2 years' follow-up were included (THA: n = 140,336; TKA: n = 117,497; UKA: n = 14,807). We performed multivariable Cox regression analyses to calculate hazard risks for differences between smokers and non-smokers, while adjusting for confounders (aHR).

RESULTS

The smoking group had higher risk of revision (THA: aHR 1.3, 95% confidence interval [CI] 1.1-1.4 and TKA: aHR 1.4, CI 1.3-1.6) and risk of mortality (THA: aHR 1.4, CI 1.3-1.6 and TKA: aHR 1.4, CI 1.2-1.6). Following UKA, smokers had a higher risk of mortality (aHR 1.7, CI 1.0-2.8), but no differences in risk of revision were observed. The smoking group had a higher risk of revision for infection following TKA (aHR 1.3, CI 1.0-1.6), but not following THA (aHR 1.0, CI 0.8-1.2).

CONCLUSION

This study showed that the risk of revision and mortality is higher for smokers than for non-smokers in the first 2 years following THA and TKA. Smoking could contribute to complications following primary hip or knee arthroplasty.

[Physical activity and its influencing factors in patients with diabetes mellitus: a comparative study between China and the United Kingdom]

Objective: To compare the differences in low-level physical activity (PA) and related influencing factors in patients with diabetes mellitus in China and the United Kingdom (UK). Methods: Using baseline survey data from the China Kadoorie Biobank and the UK Biobank, we analyzed the association between diabetes mellitus and low-level PA using logistic regression, with the participants' self-reported whether they had diabetes mellitus as the independent variable, and low-level PA as the dependent variable. Results: We included 509 254 Chinese adults and 359 763 British adults in the analysis. After adjusting for multiple factors, we found that both Chinese and British patients with diabetes mellitus were at elevated risk for low-level PA, with corresponding ORs (95%CIs) of 1.15 (1.12-1.19) and 1.37 (1.32-1.41), respectively. Patients with diabetes mellitus with longer disease duration and poorer glycemic control were at greater risk of having low-level of PA. Female, rural-distributed, employed, never-smoking Chinese diabetics, and male, urban-distributed, retired/unemployed, quit-smoking British diabetics were more likely to have low-level PA. Conclusions: Chinese and British patients with diabetes mellitus were more likely to have low-level PA compared with the general population, but the risk of low-level PA for patients in both countries varied by population characteristics. Therefore, PA guidelines and intervention measures should be based on the characteristics of individuals in the target countries and regions, which could improve PA levels among patients with diabetes mellitus.

The AGE-RAGE axis associates with chronic pulmonary diseases and smoking in the Rotterdam study

BACKGROUND

Chronic obstructive pulmonary disease (COPD) and asthma associate with high morbidity and mortality. High levels of advanced glycation end products (AGEs) were found in tissue and plasma of COPD patients but their role in COPD and asthma is unclear.

METHODS

In the Rotterdam Study (n = 2577), AGEs (by skin autofluorescence (SAF)), FEV1 and lung diffusing capacity (DLCOc and DLCOc /alveolar volume [VA]) were measured. Associations of SAF with asthma, COPD, GOLD stage, and lung function were analyzed using logistic and linear regression adjusted for covariates, followed by interaction and stratification analyses. sRAGE and EN-RAGE associations with COPD prevalence were analyzed by logistic regression.

RESULTS

SAF associated with COPD prevalence (OR = 1.299 [1.060, 1.591]) but not when adjusted for smoking (OR = 1.106 [0.89, 1.363]). SAF associated with FEV1% predicted (β=-3.384 [-4.877, -1.892]), DLCOc (β=-0.212 [-0.327, -0.097]) and GOLD stage (OR = 4.073, p = 0.001, stage 3&4 versus 1). Stratified, the association between SAF and FEV1%predicted was stronger in COPD (β=-6.362 [-9.055, -3.670]) than non-COPD (β=-1.712 [-3.306, -0.118]). Association of SAF with DLCOc and DLCOc/VA were confined to COPD (β=-0.550 [-0.909, -0.191]; β=-0.065 [-0.117, -0.014] respectively). SAF interacted with former smoking and COPD prevalence for associations with lung function. Lower sRAGE and higher EN-RAGE associated with COPD prevalence (OR = 0.575[0.354, 0.931]; OR = 1.778[1.142, 2.768], respectively).

CONCLUSIONS

Associations between SAF, lung function and COPD prevalence were strongly influenced by smoking. SAF associated with COPD severity and its association with lung function was more prominent within COPD. These results fuel further research into interrelations and causality between SAF, smoking and COPD.

TAKE-HOME MESSAGE

Skin AGEs associated with prevalence and severity of COPD and lung function in the general population with a stronger effect in COPD, calling for further research into interrelations and causality between SAF, smoking and COPD.

Underreporting of non-study cigarette use by study participants confounds the interpretation of results from ambulatory clinical trial of reduced nicotine cigarettes

BACKGROUND

As part of its comprehensive plan to significantly reduce the harm from tobacco products, the US Food and Drug Administration is establishing a product standard to lower nicotine in conventional cigarettes to make them "minimally addictive or non-addictive". Many clinical studies have investigated the potential impact of such a standard on smoking behavior and exposure to cigarette constituents. These ambulatory studies required participants who smoke to switch to reduced nicotine study cigarettes. In contrast to clinical trials on pharmaceuticals or medical devices, participants had ready access to non-study conventional nicotine cigarettes and high rates of non-study cigarette use were consistently reported. The magnitude of non-compliance, which could impact the interpretation of the study results, was not adequately assessed in these trials.

METHODS

We conducted a secondary analysis of data from a large, randomized trial of reduced nicotine cigarettes with 840 participants to estimate the magnitude of non-compliance, i.e., the average number of non-study cigarettes smoked per day by study participants assigned to reduced nicotine cigarettes. Individual participants' non-study cigarette use was estimated based on his/her urinary total nicotine equivalent level, the nicotine content of the study cigarette assigned and the self-reported number of cigarettes smoked, using a previously published method.

RESULTS

Our analysis showed that (1) there is a large variation in the number of non-study cigarettes smoked by participants within each group (coefficient of variation 90-232%); (2) participants in reduced nicotine cigarette groups underreported their mean number of non-study cigarettes smoked per day by 85-91%; and (3) the biochemical-based estimates indicate no reduction in the mean number of total cigarettes smoked per day for any group assigned to reduced nicotine cigarettes after accounting for non-study cigarettes.

CONCLUSIONS

High levels of non-compliance, in both the rate and magnitude of non-study cigarette use, are common in ambulatory reduced nicotine cigarette trials where participants have access to conventional nicotine non-study cigarettes. The potential impact of high non-compliance on study outcomes should be considered when interpreting the results from such ambulatory studies.

Associations between Health-Related Use of Social Media and Positive Lifestyle Behaviors: Findings from a Representative Sample of US Adult Smokers

Background: Cigarette smokers have elevated cardiovascular risk factors, which contributes significantly to mortality. Although social media is a potential avenue to deliver smoking interventions, its role in health promotion among smokers remains relatively unexplored.Objective: To examine the uptake and impact of health-related social media use in cigarette smokers.Methods: Using data from the 2017-2020 Health Information National Trends Survey, we evaluated differences in health-related social media use between smokers and nonsmokers. Multivariable logistic regression was performed to examine the association between social media use and positive health behaviors.Results: We included 1863 current smokers and 13,560 nonsmokers; Most participants were women (51.0%), White (64.6%), and 49.2% were aged ≥50 years. Smokers who used ≥1 social media site for health-related purposes in the past year were significantly more likely to meet the guideline recommendations for: (i) weekly physical activity (AOR 2.00, 95% CI 1.23-3.24), (ii) daily vegetable intake (AOR 2.48, 95% CI 1.10-5.59), and (iii) weekly strength training (AOR 1.80, 95% CI 1.10-2.94). However, the odds of reporting intentions to quit smoking (AOR 1.81, 95% CI 0.98-3.34) and attempts at smoking cessation (AOR 1.68, 95% CI 0.90-3.12) did not differ by health-related social media use.Conclusion: Smokers use social media for health-related purposes at comparable rates to nonsmokers. While our findings indicate that these platforms present a novel opportunity for health promotion among smokers, future research exploring the utility of social media in smoking cessation is crucial.

Prevalence of precancerous lesions and other cervical abnormalities among internally displaced women in Benue State Nigeria

Introduction

visual inspection is a low-cost screening strategy that can be used to prevent cervical cancer in women. These techniques can improve screening health outcomes for internally displaced women (IDW) who have poor sexual and reproductive health and rights' behaviors and outcomes. This study aimed to determine the prevalence of precancerous lesions and other clinical features using a visual inspection with acetic acid (VIA) technique during a cervical cancer screening campaign in two internally displaced people (IDP) camps in Benue State, Nigeria.

Methods

this was a cross-sectional study of 166 IDW who voluntarily participated in the study during a VIA cervical cancer screening campaign in two IDP camps in Benue State, Nigeria the screening was done by a group of qualified and trained healthcare workers and data was collected using a structured, pretested questionnaire.

Results

a total of 99(60%) of the women had a first sexual experience at 16 years, while 78(47%) had more than 5 full-term pregnancies. Although only 72(43.4%) of the women acknowledged having more than one sexual partner, over 70% of the women stated that their sexual partner had another sexual partner. The prevalence of precancerous lesions among women was 10.8%. Smoking(p=0.003), age at menarche (p≤ 0.001) and sexual behaviors (p=0.009, p=0.004) were factors that had a statistically significant relationship with the presence of a precancerous lesion among the IDW. The study also highlights the high rate (95%) of cervicitis among the women and the relatively high rate (5.4%) of leukoplakia.

Conclusion

the majority of IDW had sociodemographic and lifestyle characteristics that predisposed them to developing cervical cancer More targeted interventions aimed at improving the sociodemographic and lifestyle characteristics of IDW are recommended. In addition, there is a need to create awareness about cervical cancer among IDW and make screening available in camp facilities for early detection and management.

Smoking and BMI mediate the causal effect of education on lower back pain: observational and Mendelian randomization analyses

Objective

Low back pain (LBP) has been associated with education in previous observational studies, but the causality remains unclear. This study aims to assess the impact of education on LBP and to explore mediation by multiple lifestyle factors.

Design

Univariable Mendelian randomization (MR) was performed to examine the overall effect of education on LBP. Subsequently, multivariable MR was conducted to assess both the direct effect of education on LBP and the influence of potential mediators. Indirect effects were estimated using either the coefficient product method or the difference method, and the proportion of mediation was calculated by dividing the indirect effect by the total effect. The observational study utilized data from the NHANES database collected between 1999 and 2004, and included 15,580 participants aged 20 years and above.

Results

Increasing education by 4.2 years leads to a 48% reduction in the risk of LBP (OR=0.52; 95% CI: 0.46 to 0.59). Compared to individuals with less than a high school education, those with education beyond high school have a 28% lower risk of LBP (OR=0.72; 95% CI: 0.63 to 0.83). In the MR study, smoking accounts for 12.8% (95% CI: 1.04% to 20.8%) of the total effect, while BMI accounts for 5.9% (95% CI: 2.99% to 8.55%). The combined mediation effect of smoking and BMI is 27.6% (95% CI: 23.99% to 32.7%). In the NHANES study, only smoking exhibits a mediating effect, accounting for 34.3% (95% CI: 21.07% to 41.65%) of the effect, while BMI does not demonstrate a mediating role.

Conclusions

Higher levels of education provide a protective effect against the risk of LBP. Additionally, implementing interventions to reduce smoking and promote weight loss among individuals with lower levels of education can also decrease this risk.
