Global burden of disease due to smokeless tobacco consumption in adults: analysis of data from 113 countries

Perceptions and usage of traditional cigarettes, electronic cigarettes, and waterpipes among young and middle-aged adults in Iraq: A descriptive study

Tobacco use poses significant public health concerns, linked to various mental and physical health outcomes. Iraq has a high prevalence of smoking, predominantly with traditional cigarettes, but there is also growing popularity of electronic cigarettes and waterpipes among younger and middle-aged adults. This study aims to explore the perceptions and usage of traditional cigarettes, electronic cigarettes, and waterpipes among this population in Iraq. A descriptive study was conducted among 402 young and middle-aged adults (50.25% females), aged between 18 and 45 years, with a mean age of 25.88 (SD = 7.27). For the data collection, an online questionnaire was developed utilizing distribution channels on common social networking platforms. The results showed that 41.79% of respondents have used traditional cigarettes, while 31.1% of participants reported that they use electronic cigarettes. Ninety-four per cent of respondents acknowledged that they use waterpipes. The results also indicated that a significant proportion believe that using electronic cigarettes is either much more harmful or more harmful than traditional cigarettes. Participants commonly perceived all three types of tobacco products as highly harmful, including secondhand smoke, addictive qualities, and popularity among peers. Additionally, significant differences in perceptions emerged between smokers and nonsmokers regarding electronic cigarettes and traditional cigarettes, although no such differences were observed for waterpipes. These findings contribute to understanding the attitudes toward different forms of tobacco use among respondents, highlighting the need for targeted interventions to address the perceived harm associated with tobacco products.

Trends in smokeless tobacco use and attributable mortality and morbidity in the South-East Asia Region: implications for policy

OBJECTIVES

To describe the prevalence of smokeless tobacco (SLT) use and number of users by year, in addition to trends in mortality and attributable disease burden in countries of the WHO South-East Asia Region (SEAR), to inform policies for SLT control in the Region.

METHODS

For each SEAR country, we obtained data from Global Adult Tobacco Surveys, WHO STEPwise Approach to NCD Risk Factor Surveillance surveys and Demographic and Health Surveys conducted since 2010 to estimate prevalence of SLT use by country, sex and year. Using data from the World Population Prospects database we estimated the number of users by country. Next, using the results of previous meta-analyses and prevalence results, we estimated the population attributable fractions and attributable mortality and morbidity in terms of annual deaths and disability-adjusted life years lost. We then characterised trends in attributable deaths and disease burden for countries with comparable data.

RESULTS

There were wide differences in SLT use prevalence by country. We estimated that, during 2015-2019, there were 165 803 900 SLT users across SEAR, with 479 466 attributable deaths annually of which India accounted for 79.9% with 383 248. Attributable annual deaths increased in some countries during 2015-2019.

CONCLUSIONS

Annual deaths and disease burden attributable to SLT remain high across SEAR and have only declined modestly in recent years. Effective implementation of all WHO Framework Convention on Tobacco Control measures, addressing both supply-side and demand-side issues, in relation to SLT and areca nut products must be prioritised to ensure reductions in mortality and disease burden are sustained and accelerated.

Which countries are ready for a tobacco endgame? A scoping review and cluster analysis

Various countries have set tobacco endgame targets to eliminate tobacco use by a certain year. Tobacco endgames are generally considered more feasible in countries with advanced tobacco control measures and a smoking prevalence of 15% or less. We conducted a scoping review of 563 articles sourced from news, academic literature, and grey literature to examine global tobacco endgame progress, and grouped 153 countries into clusters based on their tobacco policy implementation score and smoking prevalence to systematically identify countries that might be well positioned to succeed in a tobacco endgame. The EU, Pacific Islands, and 18 other individual countries have set tobacco endgame targets, with another seven countries described as well positioned for an endgame. These were mostly high-income countries with higher smoking prevalence. We identified 28 endgame-ready countries with advanced tobacco policies and a low smoking prevalence. Of these, only five were part of tobacco endgame movements; the remaining 23 were all low-income or middle-income countries in Africa, Latin America, or Asia. Therefore, the global tobacco endgame movement should focus more on low-income and middle-income countries with low smoking rates and advanced tobacco policies, particularly in Africa, Latin America, and Asia.

Trend over time on knowledge of the health effects of cigarette smoking and smokeless tobacco use in Bangladesh: Findings from the International Tobacco Control Policy Evaluation Bangladesh Surveys

INTRODUCTION

Cigarette smoking and smokeless tobacco (ST) use are prevalent in Bangladesh. This longitudinal study examined how knowledge of the health effects of smoking and ST use in Bangladesh has changed overtime with the country's acceleration of tobacco control efforts.

METHODS

Data were analysed from the International Tobacco Control Survey, a nationally representative longitudinal study of users and non-users of tobacco (aged 15 and older) in Bangladesh, across four waves conducted in 2009 (n = 4378), 2010 (n = 4359), 2012 (n = 4223) and 2015 (n = 4242). Generalised estimating equations assessed the level of knowledge about harms of tobacco use across four waves. Multivariable logistic regressions assessed whether knowledge of health effects from cigarette smoking and ST use in 2015 differed by user group.

RESULTS

In 2015 survey, most tobacco users were aware that cigarette smoking causes stroke (92%), lung cancer (97%), pulmonary tuberculosis (97%) and ST use causes mouth cancer (97%) and difficulty in opening mouth (80%). There were significant increases in the total knowledge score of smoking related health harm from 2010 to 2012 (mean difference = 0.640; 95% confidence interval [CI] 0.537, 0.742) and 2012 to 2015 (mean difference = 0.555; 95% CI 0.465, 0.645). Participants had greater odds of awareness for ST health effects from 2010 to 2015.

DISCUSSION AND CONCLUSIONS

The results suggest that increasing efforts of awareness policy interventions is having a positive effect on tobacco-related knowledge in Bangladesh. These policy initiatives should be continued to identify optimal methods to facilitate behaviour change and improve cessation of smoking and ST use.

Costimulatory Molecules OX40 and OX40L Upregulation in Oral Squamous Cell Carcinoma: A Blood-Based Study

OBJECTIVES

 This research aimed to determine OX40 and OX40L mRNA expression in blood samples of naive oral squamous cell carcinoma (OSCC) patients in different histological grades and clinical stages. The in silico analysis was performed using the STRING database for functional association and a better understanding of the interactions of OX40 and its ligand with other proteins.

MATERIALS AND METHODS

 In this study, we recruited 141 newly diagnosed patients of OSCC. Levels of OX40 and OX40L mRNA expression were explored using real-time quantitative polymerase chain reaction. An in silico tool was also utilized to evaluate the OX40/OX40L interactome.

RESULTS

 The results showed higher OX40 expressional levels in the late stage (23-fold) compared with the early stage (8.5-fold) (p = < 0.001). A similar trend was seen in OX40L mRNA expression, revealing a fold change of 5.8 in the early stage in comparison to 9.9-fold change in the late stage (p = < 0.001). Overexpression of OX40 and OX40L was found in different histological grades (p = 0.005 and p = < 0.001, respectively). Overexpression of OX40 and OX40L was detected in habits such as smoking and paan intake, whereas statistically significant upregulation was observed in the cheek, lip, and alveolus tumors. However, there was no substantial difference in OX40 and OX40L expression based on age or gender. The functional interactions, that is, interactomes of OX40 and OX40L with other proteins have been determined by in silico analysis.

CONCLUSION

 Based on current study findings, despite OX40 and OX40L upregulation in newly diagnosed OSCC patients, it is speculated that the physiological function of these molecules is altered due to immune system exhaustion.

Pattern of Smokeless Tobacco Initiation and Use among School Going Adolescents in Delhi, India: A Mixed Method Study

INTRODUCTION

With growing trends in tobacco consumption, it has been observed that the age of initiation is gradually decreasing. To combat the deep-rooted problem of the Society, we need to target the adolescents at the time of their first consumption of tobacco forms. Hence, this study was conducted to assess the pattern of smokeless tobacco use among school going adolescents in senior secondary schools with the assessment of the sociodemographic factors responsible for initiation of smokeless tobacco use by adolescents.

METHODS

A cross-sectional survey of total sample of 714 students across 9-11 standards in 3 schools of Delhi was done using a self-administered questionnaire after obtaining approval from Institutional Ethics Committee and School Health Scheme, Delhi.

RESULT

Consumption of tobacco was found to be 27.9% at a frequency of 6-9 days in a period of one month and a majority of 31 (39.2%) students initiated the use in the age group of 10-11 years. Among the different SLT products, pan masala combined with zarda with 56 (70.8%) users, was found to be the most commonly consumed SLT product. Grocery shops were preferred POS among the students as (67%) of students obtained the SLT product from this POS. 56 (70.8%) of the students wanted to quit the habit of SLT use whereas 49 (62%) students tried to quit the habit and 43 (54.4%) students sought help in order to quit the habit.

DISCUSSION

Such alarming results in terms of low age of initiation in Delhi is an emerging health problem. Adequate cessation programmes and schemes must be developed and strict implementation of laws and policies to achieve a tobacco free youth is the need of hour.

A cross-sectional study of attitudes and behaviors of snuff use and cessation among people with and without HIV in South Africa

Background

Despite a high (48%) prevalence of snuff use among women with HIV in South Africa, little is known of the attitudes and behaviors of use, strategies for cessation, and potential health risks.

Methods

In a cross-sectional study, a questionnaire was administered to adults (≥18 years) with (HIV+) and without HIV (HIV-) who self-reported current snuff use to collect information on demographics, snuff use and cessation attempts, preferred strategies for cessation, other substance use, history of respiratory illness, and mental health.

Results

150 (74 HIV+, 76 HIV-) participants were enrolled; 115 (77%) were daily snuff users, 6 (4%) were current smokers, and 17 (11%) former smokers. Top reasons for current snuff use included improving health (n = 48, 32%), reducing stress (n = 26, 16%), and "being a habit" (n = 38, 25%). Participants believed snuff use to have mostly positive (n = 68, 46%) or no (n = 54, 36%) health impacts, and 57 (38%) participants believed snuff cures headaches. 103 (69%) participants reported a previous quit attempt, and 110 (73%) indicated high interest in quitting snuff. Although 105 (70%) participants indicated that advice from a healthcare provider would aid them in quitting snuff, only 30 (20%) reported ever receiving that advice. A majority of participants (n = 141, 94%) suffer from moderate to high levels of perceived stress, and overall few differences were seen by HIV status.

Conclusions

Education on negative impacts of snuff, advice to quit from healthcare providers, and nicotine replacement therapy should be considered in the development of a snuff cessation program.

Effectiveness of brief counseling (5As): Antenatal tobacco cessation support program among pregnant women availing antenatal care

Introduction

It is likely that a pregnant woman is more motivated and receptive to accepting healthy habits and practices if talked about the benefits to the fetus. When explained about the harmful effects of tobacco on the health of the baby, the mother can be encouraged to modify her tobacco consumption habits and work toward quitting tobacco.

Aim

Our aim was to study the effectiveness of brief counseling (5As)-Antenatal Tobacco Cessation Support Program among pregnant women availing antenatal care (ANC).

Methodology

A quasi-randomized study design was used to conduct the study. The participants were identified by screening during ANC visits, and women consuming tobacco were subjected to detailed history taking and very brief counseling with the help of 5A's framework.

Results

We found that Mishri was the commonest form of tobacco consumed by these women. Around 93.33% of the women consume Mishri, followed by 6.66% of women consuming chewing tobacco. The method of brief counseling made an impact in the cessation of tobacco consumption in 13.37% of the study subjects.

Conclusion

We conclude that the use of brief counseling and motivational interviewing is feasible in most settings without inhibiting the other important aspects of ANC or disrupting the patient flow.

Determination of nicotine content in locally produced smokeless tobacco (Shammah) samples from Jazan region of Saudi Arabia using a convenient HPLC-MS/MS method

Shammah is one of the forms of smokeless tobacco (SLT) prepared by mixing tobacco powder with other ingredients to increase its acceptability. Nicotine (NT) is the main alkaloid present in tobacco and is a precursor for carcinogenic metabolites including tobacco specific nitrosamines (TSNAs). In this study, eight varieties of Shammah samples, collected from Jazan region of Saudi Arabia, were analyzed for NT content by a validated high performance liquid chromatography-mass spectrometry/mass spectrometry method. Electrospray ionization was used with the multiple reaction monitoring in the positive mode for data acquisition. The method was fast and short retention times (RT) of 1.4 and 3.1 min were observed for NT and lapatinib used as internal standard (IS), respectively. The inter- and intra-day accuracy and precision results met the acceptance criteria of United States Food and Drug Administration and International Council for Harmonisation validation guidelines. The developed method was successfully applied for the detection of NT contents in various Shammah samples. NT concentration was found to be in the range of 6.94 ± 0.16 to 31.69 ± 0.79% with the maximum level detected in special Shammah from Ahad Al Masarihah and the lowest level in Khadrah Shammah from Samtah city. The results of this investigation have warranted further research to determine the minor Shammah contents including additive materials and assessment of associated health effects.

Heightened risks of cardiovascular disease in South Asian populations: causes and consequences

INTRODUCTION

South Asian individuals comprise almost a quarter of the world's population and have an excess risk of atherosclerotic cardiovascular disease (ASCVD) compared to other ethnicities. In part, this can be explained by higher prevalence, earlier onset, and suboptimal control of traditional cardiovascular risk factors, such as insulin resistance, metabolic syndrome, and dyslipidaemia. However, there remains a significant residual excess risk associated with South Asian ethnicity after controlling for traditional risk factors.

AREAS COVERED

In this review, we describe the epidemiology of ASCVD in both native and diaspora South Asian populations. We explore how traditional cardiovascular risk factors, novel cardiovascular risk factors, and social determinants of health may contribute to the excess ASCVD risk seen in South Asian populations.

EXPERT OPINION

There should be increased awareness of the relative importance of South Asian ethnicity and related social determinants of health, as risk factors for ASCVD. Systematic screening processes should be tailored to this population, and modifiable risk factors should be treated aggressively. Further research is required to quantify determinants of the excess ASCVD risk seen in South Asian populations and to develop targeted interventions to address these factors.

Awareness, perceptions of and compliance with tobacco control policies among naswar vendors in Khyber Pakhtunkhwa Pakistan

INTRODUCTION

Regulatory compliance in the retail environment is integral to the success of tobacco control. We assessed compliance among naswar (smokeless tobacco product widely used in South Asia) vendors with tobacco control laws. We also assessed their awareness of tobacco-related harms and policies and perceived effect of policies on their sales.

METHODS

We surveyed 286 naswar vendors in three districts of the Khyber Pakhtunkhwa province of Pakistan. We recruited general and specialty vendors from urban and rural areas through multistage cluster sampling. Compliance was measured for promotion, sale to/by minors and tax paid on naswar. We used logistic regression analyses for assessing the association between the outcome variables (awareness of tobacco harms and laws, perceptions about the effect of policies on business and compliance with laws) and their predictors.

RESULTS

Most vendors (70%) were aware of tobacco-related harms of naswar. Although educated vendors were more aware of tobacco control policies, the greatest awareness was for a ban on sales to/by minors (21% overall). The majority of vendors (76%) violated this policy (measured by self-report), and violations were more common among rural than urban vendors (OR 2.27, 95% CI 1.05 to 4.96). Most vendors (71%) violated a ban on promotion of naswar. Vendors perceived tax increases and sales ban to/by minors as most detrimental for business.

CONCLUSIONS

There was poor awareness and compliance among naswar vendors in Pakistan with tobacco control laws. This study finds potential areas for policy interventions that can reduce urban/rural disparities in implementation of and compliance with tobacco control laws.

Tobacco chewing and associated factors among a vulnerable youth population in Sri Lanka

BACKGROUND

Tobacco in any form kills millions of people every year. Tobacco addiction among youth shows an increasing trend while smokeless type is becoming more common. This study aimed to describe the lifestyle of chewing smokeless tobacco among a group of high-risk youth population in Sri Lanka.

METHODS

A descriptive cross-sectional study was conducted among a sample of 1431 youths aged between 15 to 24 years residing in urban slums in Colombo Sri Lanka, using a cluster sampling technique combined with probability proportionate to size technique. Data were collected using an interviewer-administered questionnaire. Chewing smokeless tobacco was assessed using betel quid chewing and commercially prepared tobacco and areca nut packet chewing. Current chewer was defined as who had the practice of chewing during past 30 days.

RESULTS

The mean age of the study sample was 17.53 (95% CI: 17.40-17.65). Of the 1431 respondents, 57% were males and 43% were females. The prevalence of current smokeless tobacco chewers was 44.9% and among them 90.8% were males and 9.8% were females. Around 31.3% did not have smokeless tobacco chewing practice (Male-5.9%, Female-64.9%). Among the current smokeless tobacco chewers 21.5% chew both types of smokeless tobacco products and all of them were males. Male gender (OR 17.9; 11.4 -27.9) and ever smoking lifestyle (OR 4.4; 2.9-6.6) were significant determinants of current smokeless tobacco chewing lifestyle.

CONCLUSION AND RECOMMENDATIONS

The study shows a high prevalence of smokeless tobacco use by youth aged between 15 to 24 years who were residing in urban slum areas in the district of Colombo, in Sri Lanka, highlighting this target group for early intervention to reduce the uptake and promote the quitting of this practice.

Prevalence of tobacco consumption and the associated factors among the adults in an urban slum: Findings from the WHO STEPwise survey

INTRODUCTION

Despite Pakistan's stringent tobacco control policy, its effective implementation has always been a challenge, leading to rising tobacco consumption. The aim of the study is to determine the prevalence of tobacco consumption and associated risk factors in the adult population of deprived urban areas.

METHODS

A community-based, cross-sectional survey was conducted from February to July 2019, comprising 607 adults residing in the urban squatter settlement of Lahore using a standardized questionnaire, the WHO STEPwise approach. The outcome was current use of tobacco and/or smokeless tobacco daily. Multivariable logistic regression was applied to determine factors associated with smoking and smokeless tobacco consumption.

RESULTS

Among 607 participants, about 64% were females, 49.3% were illiterate, 64.9% were currently unemployed, and 47.1% belonged to the low-income group. The prevalence of tobacco smoke was 10.5% (95% CI: 8.07-12.93), and smokeless tobacco consumption was 8.6% (95% CI: 6.38-10.82). Multivariable logistic regression found that smokeless tobacco was more likely among the aged 50-59 years (AOR=4.1; 95% CI: 1.1-13.8) and unemployed (AOR=3.6; 95% CI: 1.1-12.2). Whereas tobacco smoking was more likely among the aged 30-39 years (AOR=5.5; 95% CI: 1.8-16.7), Urdu ethnicity (AOR=2.9; 95% CI: 1.2-7.3), unemployed (AOR=6.6; 95% CI: 2.9-14.9), and never exposed to any media (AOR=3.2; 95% CI: 1.8-17.4). Participants exposed to health warnings were less likely to smoke (AOR=0.02; 95% CI: 0.01-0.05).

CONCLUSIONS

This study reports a high prevalence of tobacco consumption among adults and calls for effective policy implementation using a multi-pronged approach, including health professionals and media, to spread awareness about the harmful effects of tobacco and endorsement of health warnings on tobacco packaging.

A set of common buccal CpGs that predict epigenetic age and associate with lifespan-regulating genes

Epigenetic aging clocks are computational models that use DNA methylation sites to predict age. Since cheek swabs are non-invasive and painless, collecting DNA from buccal tissue is highly desirable. Here, we review 11 existing clocks that have been applied to buccal tissue. Two of these were exclusively trained on adults and, while moderately accurate, have not been used to capture health-relevant differences in epigenetic age. Using 130 common CpGs utilized by two or more existing buccal clocks, we generate a proof-of-concept predictor in an adult methylomic dataset. In addition to accurately estimating age (r = 0.95 and mean absolute error = 3.88 years), this clock predicted that Down syndrome subjects were significantly older relative to controls. A literature and database review of CpG-associated genes identified numerous genes (e.g., CLOCK, ELOVL2, and VGF) and molecules (e.g., alpha-linolenic acid, glycine, and spermidine) reported to influence lifespan and/or age-related disease in model organisms.

•

130 CpGs have been used by two or more aging clocks applied to human buccal tissue

•

Common CpG genes are linked to the adaptive immune system and telomere maintenance

•

Common CpGs can be used to build a novel, proof-of-concept epigenetic aging clock

•

Several compounds associated with common CpG genes regulate lifespan in animals

Combining Phenotypes of Nucleotide Excision Repair Pathway to Predict the Risk of Head and Neck Squamous Cell Carcinomas in a Chinese Population

Background

Nucleotide excision repair (NER) is pivotal in the development of smoking-related malignancies. Nine core genes (XPA, XPB, XPC, XPD, XPF, XPG, ERCC1, DDB1, and DDB2) are highly involved in the NER process. We combined two phenotypes of NER pathway (NER protein and NER gene mRNA expression) and evaluated their associations with the risks of the head and neck squamous cell carcinomas (HNSCCs) in a Chinese population.

Methods

We conducted a case-control study of 337 HNSCC patients and 285 cancer-free controls by measuring the expression levels of nine core NER proteins and NER gene mRNA in cultured peripheral lymphocytes.

Results

Compared with the controls, cases had statistically significantly lower protein expression levels of XPA (P < 0.001) and lower mRNA expression levels of XPA and XPB (P = 0.005 and 0.001, respectively). After dividing the subjects by controls' medians of expression levels, we found an association between increased risks of HNSCCs and low XPA protein level (P_trend = 0.031), as well as low mRNA levels of XPA and XPB (P_trend = 0.024 and 0.001, respectively). Subsequently, we correlated the two phenotypes and found associations between the NER mRNA and protein levels. Finally, the sensitivity of the expanded model with protein and mRNA expression levels, in addition to demographic variables, on HNSCCs risk was significantly improved.

Conclusions

Combining two phenotypes of NER pathway may be more effective than the model only including one single phenotype for the assessment of risks of HNSCCs.

The Burden of Cancer, Government Strategic Policies, and Challenges in Pakistan: A Comprehensive Review

Cancer is a severe condition characterized by uncontrolled cell division and increasing reported mortality and diagnostic cases. In 2040, an estimated 28.4 million cancer cases are expected to happen globally. In 2020, an estimated 19.3 million new cancer cases (18.1 million excluding non-melanoma skin cancer) had been diagnosed worldwide, with around 10.0 million cancer deaths. Breast cancer cases have increased by 2.26 million, lung cancer by 2.21 million, stomach by 1.089 million, liver by 0.96 million, and colon cancer by 1.93 million. Cancer is becoming more prevalent in Pakistan, with 19 million new cancer cases recorded in 2020. Food adulteration, gutkha, paan, and nutritional deficiencies are major cancer risk factors that interplay with cancer pathogenesis in this country. Government policies and legislation, cancer treatment challenges, and prevention must be revised seriously. This review presents the current cancer epidemiology in Pakistan to better understand cancer basis. It summarizes current cancer risk factors, causes, and the strategies and policies of the country against cancer.

Cytotoxicity, oxidative stress, and inflammatory response of smokeless tobacco extracts and cytotoxicity of combustible cigarette whole smoke in a 3D oral organotypic buccal cell model

Oral disease is frequently associated with viral and environmental exposures and oral hygiene. The use of tobacco is a risk factor in the development of oral disease. Cytotoxicity, inflammatory response, and oxidative stress have been reported to have a role in the development of oral disease. These three endpoints were evaluated in a 3D human oral buccal model, EpiOral™, following exposure to CORESTA reference smokeless tobacco products (CRPs) and cigarette whole smoke. CRPs for Swedish style snus (CRP1), moist snuff (CRP2), and dry snuff (CRP3) were each extracted in complete artificial saliva (CAS) with a ratio of 300 mg CRP to 1 mL of CAS. Each of the CRP extracts (15-300 mg/ml) were applied to the apical side of a 3D organotypic buccal cell model for 24 or 48 h continuously, then cytotoxicity (LDH), oxidative stress (8-isoprostane), and inflammatory response (IP10, IL-1α, and IL-8) were measured. Experiments with 3R4F cigarettes were conducted by exposing the buccal tissues to whole smoke for a maximum of 2.5 h. Cytotoxicity (MTT) was measured 24 h post-exposure. Exposure of buccal tissues to whole smoke from a cigarette induced a dose-dependent cytotoxic response. In contrast, the CRP extracts elicited minimal cytotoxicity (<15%) when compared to CAS (vehicle control), but time- and dose-dependent effects on oxidative stress and inflammatory response were observed. Collectively, these data demonstrate that a 3D organotypic buccal human model may be used to assess biological mechanisms (MOAs) involved in the development of oral disease following exposure to smokeless tobacco products and may be applicable for differentiation between tobacco product categories.

A Study of Head and Neck Cancer Patients with Reference to Tobacco Use, Gender, and Subsite Distribution

Context  Head and neck cancer (HNC) is very common in India, constituting 30% of all the cancers because of the widespread use of tobacco across India. The prevalence and pattern of tobacco use vary in different regions and states of the country. Although predominantly seen in males, studies have reported that the male-to-female ratio varies worldwide and also by anatomical subsite.

Aims  This study was done with an aim to determine the difference in pattern and prevalence of tobacco use in male and female patients with HNCs and compare them with different subsites' involvement in our region.

Methods and Materials  This is a retrospective analysis of 500 consecutive biopsy-proven HNC patients from a large comprehensive cancer hospital from Bihar during the period of January 2019 to June 2019. Data collected for the study included age, gender, site of the disease, and use of tobacco. The categorical data were analyzed by a chi-square test using SPSS (version 16).

Results  Our study showed a male-to-female ratio of 8.43:1 with tobacco addiction in 84.40% patients. Smokeless tobacco was used by 52.20%, combustible form by 12.80%, and both by 19.40% of the patients. Tobacco use was seen in 87.25% of male patients as compared with only 60.38% of female patients ( p -value = 0.0001). Oral cavity cancer was seen in 60.85% of male patients and 37.74% of female patients ( p -value = 0.0012), whereas oropharyngeal cancer was seen in only 11.63% of male patients as compared with 25.83% of female patients ( p -value = 0.0008). The subsite analysis showed that in patients with oral cavity cancers, no addiction was found in only 10.29% of male patients as compared with 30% of the female patients ( p -value = 0.008).

Conclusions  Our study confirms a high prevalence of tobacco use among HNC patients. So, we need to continue our efforts to create awareness against tobacco use. Besides, there is also a need for more studies to look into other etiological factors among nontobacco users.

Evaluating the impact of culturally specific patient-centric behavioral intervention package versus usual care for tobacco cessation among patients attending noncommunicable disease clinics in North India: A single-blind trial pilot study protocol

Background

In a low and middle-income country (LMIC) like India, non—communicable diseases (NCDs) contribute a major proportion (61.8%) of all causes of death. Out of this, 48% of cardiovascular diseases , 23% of Chronic Respiratory Diseases , and 10% of Cancer deaths are attributable to tobacco use. Tobacco use is a major risk factor for NCDs and thus, the tobacco cessation approach is a high priority intervention to combat complications and death among NCD patients. While several interventions are available for tobacco cessation, in resource constraint countries like India, the effectiveness of low-cost, culturally specific patient-centric tobacco cessation behavioral intervention holds a potential that needs to be evaluated. A newly developed evidence-based tobacco cessation intervention package will be compared with the existing/usual care provided under the National Programme for Prevention and Control of Cancers, Diabetes, Cardiovascular Diseases, and Stroke (NPCDCS) at NCD clinics.

Methods and design

2 arm, parallel-group randomized controlled trial.

Participants

Patients aged ≥30 years suffering from NCD, currently using tobacco, and attending NCD clinics in 2 districts of Punjab, India.

Sample size

A total of 200 participants meeting the selection criteria will be recruited. They will be allocated either to the intervention arm or control (usual care) arm (100 each) using block randomization.

Intervention

For the participants, there will be 4 face-to-face disease-specific cessation counseling sessions, disease-specific pamphlets, short text messages in vernacular language, that is, Punjabi. Follow-ups will be done at the third, sixth, ninth, and 12th months.

Primary outcome

Seven-day abstinence, biochemically verified by plasma cotinine levels.

Secondary outcome

Quit attempts, number of sticks/number of times of smokeless tobacco usage in a day, and stage of behavior change in tobacco users.

Discussion

This multicomponent culturally specific-patient-centric behavioral intervention package for tobacco cessation at NCD clinic settings focusing on the individual, family, and social environment could increase the outreach of cessation services using existing resources, thereby strengthening health systems and enhancing the quality of life of NCD patients.

Trial registration

The protocol for the study has been registered with the Clinical Trials Registry in India under the registration number CTRI/2018/01/011643.

Effect of quitting smoking on health outcomes during treatment for tuberculosis: secondary analysis of the TB & Tobacco Trial

BACKGROUND

Despite treatment, patients with tuberculosis (TB) who smoke have poorer outcomes compared with non-smokers. It is unknown, however, if quitting smoking during the 6 months of TB treatment improves TB outcomes.

METHODS

The TB & Tobacco Trial was a double-blind, placebo-controlled randomised trial of cytisine for smoking cessation in 2472 patients with pulmonary TB in Bangladesh and Pakistan. In a secondary analysis, we investigated the hypothesis that smoking cessation improves health outcomes in patients during the TB treatment course. The outcomes included an eight-point TB clinical score, sputum conversion rates, chest X-ray grades, quality of life (EQ-5D-5L), TB cure plus treatment completion rates and relapse rates. These were compared between those who stopped smoking and those who did not, using regression analysis.

RESULTS

We analysed the data of 2273 (92%) trial participants. Overall, 25% (577/2273) of participants stopped smoking. Compared with non-quitters, those who quit had better TB cure plus treatment completion rates (91% vs 80%, p<0.001) and lower TB relapse rates (6% vs 14%, p<0.001). Among quitters, a higher sputum conversion rate at week 9 (91% vs 87%, p=0.036), lower mean TB clinical scores (-0.20 points, 95% CI -0.31 to -0.08, p=0.001) and slightly better quality of life (mean EQ-5D-5L 0.86 vs 0.85, p=0.015) at 6 months were also observed. These differences, except quality of life, remained statistically significant after adjusting for baseline values, trial arm and TB treatment adherence rates.

CONCLUSION

Patients with TB who stop smoking may have better outcomes than those who don't. Health professionals should support patients in stopping smoking.

The health impact of smokeless tobacco products: a systematic review

INTRODUCTION

The objective was to systematically review studies on health outcomes from smokeless tobacco (SLT) products.

METHODS

We analysed published literature on the health outcomes from SLT use between 01/01/2015 to 01/02/2020, following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) protocol using PubMed, Embase, Scopus, and Google Scholar.

RESULTS

Of 53 studies included, six were global, 32 from Asia, Middle East and Africa (AMEA), nine from USA and six from Europe. 'Poor'-rated studies predominated (23;43%), in particular, for global (4;66%) and AMEA (16;50%). Health outcomes differed between SLT-products and regions; those in AMEA were associated with higher mortality (overall, cancer, Coronary heart disease (CHD), respiratory but not cardiovascular disease (CVD)), and morbidity (CVD, oral and head and neck cancers), with odds ratios up to 38.7. European studies showed no excess mortality (overall, CVD, from cancers) or morbidity (ischemic heart disease (IHD), stroke, oral, head and neck, pancreatic or colon cancers) from several meta-analyses; single studies reported elevated risk of rectal cancer and respiratory disorders. Pooled study data showed protection against developing Parkinson's disease. US studies showed mixed results for mortality (raised overall, CHD, cancer and smoking-related cancer mortality; no excess risk of respiratory or CVD mortality). Morbidity outcomes were also mixed, with some evidence of increased IHD, stroke and cancer risk (oral, head and neck). No studies reported on switching from cigarettes to SLT-products.

CONCLUSION

Our review demonstrates stark differences between different SLT-products in different regions, ranging from zero harm from European snus to greatly increased health risks in AMEA. The literature on the safety profile for SLT-products for harm reduction is incomplete and potentially misinforming policy and regulation.

Oral lesions associated with smokeless tobacco users in Saudi Arabia: Single center cross-sectional study

Introduction

Smokeless tobacco (SLT) causes significant harm to the oral cavity and is considered a risk factor for oral cancer. Various forms, products, and patterns of SLT are used across different populations. Many products, such as nicotine and betel nut, have addictive and carcinogenic properties. SLT use is associated with benign, premalignant, or malignant lesions. This study aimed to identify the characteristics of these oral lesions and their association with SLT exposure.

Materials and methods

This cross-sectional study, performed at our institution’s Faculty of Dentistry, included all the patients with a history of using SLT within a 5-year period at the oral medicine clinic. The patients’ demographic details were collected, and information regarding habit, duration, frequency, site of placement, and history of habit discontinuity were recorded. If a biopsy was performed, the diagnoses were also reported.

Results

Of the 59 patients included, 89.8% were male and 10.2% were female. SLT lesions in the oral cavity were usually focal lesions (76.3%). The most preferred placement site by SLT users was the mandibular posterior vestibule. Follow-up of SLT patients after quitting or clinical changes in the placement site showed a 92.8% regression or complete healing of the lesions. Of the 59 patients who underwent SLT, 18.6% were diagnosed with oral squamous cell carcinoma.

Conclusion

This study demonstrated a high percentage of remarkable regression or complete healing of SLT lesions related to early diagnosis and habit change. In contrast, 18.6% of the lesions progressed to SCC.

The effect of theory - Based educational intervention on consumption of smokeless tobacco products by merchants' guilds

BACKGROUND

Smokeless tobacco (SLT) products are highly addictive and contain at least 28 carcinogenic chemicals. The purpose of this study was to determine the effect of theory-based on the Transtheoretical Model of Behavior Change on consumption of SLT products by Merchants' Guilds in 2018.

MATERIALS AND METHODS

The present quasi-experimental research was conducted over one intervention group. The research population consisted of all consumers of the SLT products among the merchants' guilds in Chabahar City, Iran in 2018. Data were gathered from 320 individuals by simple random sampling using a valid and reliable researcher-made questionnaire. The intervention program was designed based on the Transtheoretical Model of Behavior Change cognitive processes and lasted 6 months. After the intervention, the same questionnaires were administered among the participants. The data were analyzed by SPSS version 20 using the descriptive and analytical tests.

RESULTS

In the preintervention phase, the participants' mean scores of the cognitive processes at the precontemplation, contemplation, and preparation stages were 29.16 ± 4.63, 25.07 ± 3.84, and 12.12 ± 1.63, respectively. At the postintervention phase, mean scores of the precontemplation, contemplation, and preparation stages reached to 40.5 ± 5.96, 38.8 ± 5.03, and 35.5 ± 4.23, respectively. Furthermore, the participants' mean sores at the action and maintenance stages were 36.4 ± 4.57 and 43.3 ± 3.29, respectively. According to the ANOVA, a significant relationship was found between cognitive processes at the preintervention phase and stages of change (P < 0.001).

CONCLUSIONS

Individuals can improve from the precontemplation, contemplation, and preparation phases to the action and maintenance stages by attending based on Transtheoretical Model of Behavior Change educational interventions. It is suggested that the structure of this model be used to reduce high-risk behaviors in other occupations.

Tobacco Use Among 1 310 716 Women of Reproductive age (15-49 Years) in 42 Low- and Middle-Income Countries: Secondary Data Analysis From the 2010-2016 Demographic and Health Surveys

INTRODUCTION

Tobacco use among women, especially during pregnancy is a public health concern. There is a need to understand the diverse nature of their tobacco consumption across the globe.

METHODS

We used Demographic and Health Surveys (DHS) data collected between 2010 and 2016 from 42 low- and middle-income countries (LMICs) to estimate the prevalence of smoking, smokeless tobacco, and dual use among pregnant and non-pregnant women of reproductive age (15-49 y). We compared tobacco use between both groups adjusted for age, type of residence, education and combined wealth index, and a subgroup analysis for the South-East Asia Region (SEAR) as the tobacco use in SEAR among women is far more diverse than in other regions primarily due to the popularity of smokeless tobacco use in this region.

RESULTS

Based on the data of 1 310 716 women in 42 LMICs, the prevalence of smoking was 0.69%(95%CI: 0.51-0.90) among pregnant women and 1.09%(95%CI: 0.81-1.42) among non-pregnant women. The prevalence of smokeless tobacco use was 0.56%(95%CI: 0.33-0.84) among pregnant women and 0.78%(95%CI: 0.35-1.37) among non-pregnant women. The relative risk ratios(RRR) for smoking (0.85; 95%CI: 0.67-1.09) and smokeless tobacco use (0.81; 95%CI:0.67-1.00) were not-significantly lower among pregnant women than non-pregnant women and education and wealth index had an inverse relationship with both forms of tobacco. In SEAR, among pregnant women, the prevalence of smoking and smokeless tobacco use was 1.81% and 0.45%, respectively. However, pregnant women were 7%(RRR 1.07; 95%CI:1.02-1.12) more likely to use smokeless tobacco than non-pregnant women.

CONCLUSION

Despite the added risk of foetal harm during pregnancy, there is no evidence that the tobacco consumption between pregnant and non-pregnant women differ in 42 LMICs. A significantly higher use of smokeless tobacco among pregnant women in SEAR is of particular concern and warrants further investigation.

IMPLICATIONS

Tobacco use among women in low- and middle-income countries (LMICs) is lower than high-income countries (HICs), but this may be because LMICs are earlier in the epidemiological transition of tobacco use. If ignored as a public health issue and the tobacco industry continues to market its products to women, the level of tobacco use may rise as it did in HICs. Also, despite low prevalence rates and with no evidence that these differ among pregnant and non-pregnant women, is concerning as tobacco consumption in any form during pregnancy is associated with poor birth outcomes. This suggests a need for raising awareness about the harms of tobacco use among women in LMICs, especially during pregnancy. There is a need to develop preventive and cessation interventions to decrease tobacco use (smoking and smokeless) among women who are from low socio-economic status and less educated, as they bear the greatest burden of tobacco use.

Policy priorities for strengthening smokeless tobacco control in Bangladesh: A mixed-methods analysis

INTRODUCTION

Smokeless tobacco (ST) remains poorly regulated in Bangladesh. This study describes the prevalence and trends of ST use in Bangladesh, presents ST-related disease burden, identifies relevant policy gaps, and highlights key implications for future policy and practice for effective ST control in Bangladesh.

METHODS

We analyzed secondary data from the two rounds (2009 and 2017) of The Global Adult Tobacco Survey, estimated ST-related disease burden, and conducted a review to assess differences in combustible tobacco and ST policies. In addition, we gathered views in a workshop with key stakeholders in the country on gaps in existing tobacco control policies for ST control in Bangladesh and identified policy priorities using an online survey.

RESULTS

Smokeless tobacco use, constituting more than half of all tobacco use in Bangladesh, declined from 27.2% (25.9 million) in 2009 to 20.6% (22 million) in 2017. However, in 2017, at least 16947 lives and 403460 Disability-Adjusted Life Years (DALYs) were lost across Bangladesh due to ST use compared to 12511 deaths and 324020 DALYs lost in 2010. Policy priorities identified for ST control have included: introducing specific taxes and increasing the present ad valorem tax level, increasing the health development surcharge, designing and implementing a tax tracking and tracing system, standardizing ST packaging, integrating ST cessation within existing health systems, comprehensive media campaigns, and licensing of ST manufactures.

CONCLUSIONS

Our analysis shows that compared to combustible tobacco, there remain gaps in implementing and compliance with ST control policies in Bangladesh. Thus, contrary to the decline in ST use and the usual time lag between tobacco exposure and the development of cancers, the ST-related disease burden is still on the rise in Bangladesh. Strengthening ST control at this stage can accelerate this decline and reduce ST related morbidity and mortality.

Price differentials of tobacco products: A cross-sectional analysis of 79 countries from the six WHO regions

INTRODUCTION

Increased taxation is one of the most effective tobacco control measures. Price differentials across tobacco product types may undermine the effectiveness of taxation policies by providing the option to switch to cheaper products rather than to quit. The aim of this study was to use commercial data to compare prices and price differentials of both cigarette and non-cigarette products across countries from all geographical regions.

METHODS

We analyzed 6920 price data points (i.e. product brands) from Euromonitor Passport 2016 for 12 types of tobacco products across 79 countries from the six WHO regions: Africa (n=5), Eastern Mediterranean (n=6), Europe (n=39), the Americas (n=15), South-East Asia (n=3), and Western Pacific (n=12). For each product and country, a price differential was computed as the percentage of minimum price to the median.

RESULTS

Median cigarette prices (US$) were highest in Western Pacific countries (4.00; range: 0.80-16.20) and European countries (3.80; range: 0.80-14.00), but lowest in African countries (2.00; range: 0.80-2.20). The medians of cigarette price differentials were largest in the Eastern Mediterranean (48.33%) and African regions (50.00%), but smallest in Europe (82.35%). Pipe tobacco and fine-cut tobacco were generally less expensive than cigarettes while cigars were the most expensive. However, there were wide variations in prices and price differentials across regions and tobacco products.

CONCLUSIONS

We found substantial variations in prices and price differentials between countries and world regions across tobacco products, likely reflecting differences in taxation policies and structures. Findings identify types of tobacco products in specific geographical regions where price differentials are highest, thereby highlighting areas where taxation policies need improvement, for example through implementing specific excise taxes.

Depression and anxiety among individuals with medical conditions during the COVID-19 pandemic: Findings from a nationwide survey in Bangladesh

BACKGROUND

Coronavirus disease 2019 (COVID-19) disproportionately impacts individuals with medical conditions, including with respect to their mental health. The present study investigated depression and anxiety and their correlates among individuals with medical conditions in Bangladesh.

METHODS

Subjects were recruited to participate in an internet-based survey. Data were collected from November 2020 to January 2021 using convenience sampling by a semi-structured questionnaire through online platforms. Multiple regression analyses were performed to determine associations applying Bonferroni correction (p < 0.004). The Patient Health Questionnaire (PHQ-9) and Generalized Anxiety Disorder (GAD-7) measured depression and anxiety, respectively.

RESULTS

Nine-hundred-and-seventy-one participants (50.1% male; mean age = 42.29 ± 15.86 years; age range = 18-80 years) with medical conditions were included in final analyses. The most frequently reported conditions were diabetes, hypertension, obesity, heart disease, asthma, and anemia. Estimates of moderate to severe depression and anxiety were 38.9% and 35.2%, respectively. The mean depression and anxiety scores were significantly higher among participants who reported having hypertension, obesity, heart disease, asthma, anemia, cancer and chronic obstructive pulmonary disease (COPD). Using Bonferroni correction (p < 0.004), depression was associated with being female and a student, having poorer quality of life, poorer health status and greater numbers of co-morbidities, not engaging in physical exercise and tobacco smoking. Anxiety was associated with being female and a student, having lower socioeconomic status, poorer quality of life, poorer health status and greater numbers of co-morbidities, less sleep and tobacco smoking.

CONCLUSIONS

Depression and anxiety are prevalent among individuals with medical conditions and correlate with sociodemographic, quality-of-life and smoking measures. Interventions targeting vulnerable groups should be employed and investigated.

Implementing smokeless tobacco control policy in Pakistan: a qualitative study among Naswar supply chain actors

OBJECTIVE

To obtain insights into the perceptions of barriers and facilitators to implementation of the WHO Framework Convention on Tobacco Control (FCTC) among smokeless tobacco (SLT) supply chain actors in the Khyber Pakhtunkhwa province of Pakistan.

METHODS

We conducted a qualitative study to investigate the perceptions about SLT control policy formulation and implementation among exclusive Naswar sellers and point of sale vendors. We conducted five focus group discussions in three districts of Khyber Pakhtunkhwa using combined deductive-inductive thematic analyses.

RESULTS

We identified three central themes that potentially impact policy formulation, its implementation and application. The first theme examines the role of children in the Naswar business: as potential customers, and as potential heirs to a Naswar-selling business. A second theme targets the 'business of Naswar', which includes a specific identity of Naswar sellers, its potential to generate profits and the special case of Naswar regulation as a socially accepted and culturally rooted product. The third theme addresses the unusual ingredients of Naswar and its production process, making Naswar a health risk for consumers and producers. We also report conflicting views regarding SLT control among the supply chain actors.

CONCLUSIONS

This study provides insights into the perceptions of important SLT supply-side stakeholders regarding various SLT control policy options based on the FCTC. While there is some opposition to policy approaches like taxation and switching of business, implementing a ban on selling SLT to minors may be a viable option for policymakers in the short term.

Use of Smokeless Tobacco Before Conception and Its Relationship With Maternal and Fetal Outcomes of Pregnancy in Thatta, Pakistan: Findings From Women First Study

INTRODUCTION

Smokeless tobacco (SLT) consumption during pregnancy has adverse consequences for the mother and fetus. We aimed to investigate the effects of maternal pre-pregnancy SLT consumption on maternal and fetal outcomes in the district of Thatta, Pakistan.

AIMS AND METHODS

We conducted a secondary data analysis of an individual randomized controlled trial of preconception maternal nutrition. Study participants were women of reproductive age (WRA) residing in the district of Thatta, Pakistan. Participants were asked questions regarding the usage of commonly consumed SLT known as gutka (exposure variable). Study outcomes included maternal anemia, miscarriage, preterm births, stillbirths, and low birth weight. We performed a cox-regression analysis by controlling for confounders such as maternal age, education, parity, working status, body mass index, and geographic clusters.

RESULTS

The study revealed that 71.5% of the women reported using gutka, with a higher proportion residing in rural areas as compared with urban areas in the district of Thatta, Pakistan. In the multivariable analysis, we did not find a statistically significant association between gutka usage and anemia [(relative risk, RR: 1.04, 95% confidence interval, CI (0.92 to 1.16)], miscarriage [(RR: 1.08, 95% CI (0.75 to 1.54)], preterm birth [(RR: 1.37, 95% CI (0.64 to 2.93)], stillbirth [(RR: 1.02, 95% CI (0.39 to 2.61)], and low birth weight [(RR: 0.96, 95% CI (0.72 to 1.28)].

CONCLUSIONS

The study did not find an association between gutka usage before pregnancy and adverse maternal and fetal outcomes. In the future, robust epidemiological studies are required to detect true differences with a dose-response relationship between gutka usage both before and during pregnancy and adverse fetomaternal outcomes.

IMPLICATIONS

While most epidemiological studies conducted in Pakistan have focused on smoking and its adverse outcomes among males, none of the studies have measured the burden of SLT among WRA and its associated adverse outcomes. In addition, previously conducted studies have primarily assessed the effect of SLT usage during pregnancy rather than before pregnancy on adverse fetal and maternal outcomes. The current study is unique because it provides an insight into the usage of SLT among WRA before pregnancy and investigates the association between pre-pregnancy SLT usage and its adverse fetomaternal outcomes in rural Pakistan.

Resilience and its associated factors in head and neck cancer patients in Pakistan: an analytical cross-sectional study

INTRODUCTION

The study aimed to assess resilience and its associated factors in head and neck cancer patients, post-treatment in a low middle income country (LMIC) such as Pakistan.

METHODS

An analytical cross-sectional study was conducted from November 2019 to May 2020 among head and neck cancer patients aged at least 18 years at the largest private tertiary care hospital, in Karachi, Pakistan. Information regarding their resilience scores was collected through Wagnild and Young's Resilience scale that comprises of 14 items (RS-14). Moreover, depression and anxiety were also assessed via Hospital Anxiety and Depression Scale (HADS) and social support was assessed by Enriched Social Support Instrument (ESSI).

RESULTS

The data was analyzed by linear regression modeling. Unadjusted and adjusted beta coefficients with 95% CI were reported. A total of 250 head and neck cancer patients were recruited, 79% of them were males. Mean age of the patients was 51.59 years with 93% having high social support and only 8% having severe depression and 3% having severe anxiety. After adjusting for the covariates in multivariable analysis resilience was associated with severe depression (- 17[- 20.98,-12.93]) or borderline depression (- 4[- 8.41,-0.39]), severe anxiety (- 11 [- 17.88,-4.18]), low social support (- 6[- 9.62,-1.71]), having family members of > 6 in the household (- 2[- 4.31,-0.29), smokeless tobacco users post- treatment (10[5.79, 14.45]), and those who underwent tracheotomy (- 4[- 7.67,-0.21]). There was a significant interaction between education and role in the family (decision maker).

CONCLUSION

In Pakistan, a South Asian LMIC, collectivist culture prevails, family ties are greatly promoted thus resilience and social support is highly prevalent in head and neck cancer patients resulting in lower prevalence of depression and anxiety. Our study highlights that higher resilience is prevalent among small families less than six members, as the welfare of the individual is prioritized over multiple needs of the family. Formal Education and role in household/decision making power are effect modifiers in our study, demonstrating its protective effect on the mental health of head and neck cancer patients. High resilience scores were reported among current smokeless tobacco users as compared to quitters post treatment. Resilience-building interventions should be formulated to aid head and neck cancer patients to cope with the disease and its sequel.

Does behavioral intervention affect intention to quit? : A quasi-experimental study from primary healthcare settings in India

INTRODUCTION

Tobacco is the leading cause of death and disease in India. This study examines the effect of training intervention in behavioral counseling on intention to quit tobacco in primary healthcare settings in India. The intervention included training to improve behavioral counseling practices of primary care physicians (PCPs) based on the 5As approach to increase patients' motivation to quit tobacco.

METHODS

A quasi-experimental design was used for the study. The intervention consists of training of primary care physicians in the behavioral intervention in tobacco cessation. The intervention was conducted in twelve districts of two states in India (Rajasthan and Odisha) in 2016-2017. Four districts were randomly sampled for the study. A total of 1314 participants (intervention and control) were recruited for the study in the baseline and end-line surveys, respectively. Intention to quit in 30 days was the primary outcome measure. Difference-in-difference (DiD) logistic regression models were used separately for smokers and smokeless tobacco users to estimate the odds of intention to quit. Analysis was done in STATA Version 14.

RESULTS

The intervention and time variable had a significantly positive influence on the intention to quit tobacco among smokers. Smokers in the intervention districts had higher odds of intention to quit (OR=9.82; 95% CI: 1.67-57.72) compared to smokers in the control districts. Smokeless tobacco (SLT) users had higher odds of intention to quit (OR=3.06; 95% CI: 1.35-6.98) in the end-line survey compared to baseline survey.

CONCLUSIONS

Our findings indicate that building capacity in behavioral intervention in primary care settings can help increase the intention to quit among smokers. The observed difference in intention to quit between smokers and SLT users suggests the need of tailored counseling interventions for SLT users. There is a need for further research to design and evaluate training and behavioral interventions for SLT and dual (smoking and SLT) users in primary care settings in low- and middle-income countries.

Implementation of the Uttarakhand Tobacco Free Initiative in Schools, India, 2016

PURPOSE AND OBJECTIVES

A process evaluation, the Uttarakhand Tobacco Free Initiative (UTFI), was conducted in 49 public high schools and colleges in the state of Uttarakhand, India, to measure program implementation, provide feedback to school administrators, and identify barriers to tobacco control.

INTERVENTION APPROACH

UTFI aims to 1) raise awareness and provide education and tools for teachers and school administrators about the dangers of tobacco use and secondhand smoke, 2) encourage participation in student-led activities to promote tobacco-free initiatives, and 3) enforce tobacco-free school policies in the state of Uttarakhand.

EVALUATION METHODS

We used the CDC evaluation framework to document key components and lessons learned from the UTFI. We distributed questionnaires to 71 teachers and principals in December 2016, to assess awareness of school activities and policies related to the initiative. Descriptive statistics were computed for quantitative data, and a thematic content analysis was used for qualitative data.

RESULTS

Of the 71 participants, 66 (92.9%) were aware of tobacco use policies in schools, and 63 (88.7%) agreed policies were enforced. Sixty-six participants (93.0%) said that they taught tobacco prevention-related topics, and 41 of 70 respondents (58.6%) reported that a student-led group helped to enforce tobacco-free policies in their schools. Of 69 respondents, almost all (n = 66) reported satisfaction with UTFI implementation. Challenges identified were related to tobacco products being readily accessible near school premises, lack of tobacco prevention materials, and tobacco use by school staff.

IMPLICATIONS FOR PUBLIC HEALTH

Successes of UTFI were documented by measuring different components of the process, including implementation of program activities and teacher and principal satisfaction. Results might help enhance key processes for the initiative and highlight some barriers to implementation, such as enforcing tobacco control policy off school premises. Continued efforts are needed to prevent tobacco use among young people.

Smokeless tobacco policy in Bangladesh: A stakeholder study of compatibility with the World Health Organization's Framework Convention on Tobacco Control

INTRODUCTION

Smokeless tobacco (ST) is the predominant form of tobacco used in Bangladesh and is associated with adverse health outcomes. Bangladesh ratified the World Health Organization's Framework Convention on Tobacco Control (FCTC) in 2004. There are concerns that FCTC legislation and implementation of ST control policy is insufficient in Bangladesh. The aim of this study was to investigate the achievements and challenges of ST policy in Bangladesh and its alignment with the FCTC.

METHODS

We conducted semi-structured key informant interviews with 20 stakeholders from government and non-government offices and international funding agencies, including tobacco control advocates, policy makers and non-governmental organisation workers. We used NVivo software to create key themes and the framework method for thematic analysis.

RESULTS

Our findings revealed a lack of national policy in terms of disclosure of harmful contents, illicit trade and standardised packaging of ST. Legislation remains ineffective in relation to graphical health warnings and tax measures. Challenges to ST control identified included inadequate law enforcement; paucity of research, surveillance, and evidence generation; and supply chain control. We identified lack of congruence of ST policies with FCTC due to slow progress in implementation of FCTC measures, lack of a country-specific policy and industry interference. To comply with FCTC, participants recommended strong leadership and political commitment, co-ordination between public and private sectors and proper use of tobacco control resources.

DISCUSSION AND CONCLUSIONS

Bangladesh has adopted several important FCTC measures, but further strengthening of ST policy is needed to enable full implementation of FCTC.

Awareness regarding the adverse effect of tobacco among adults in India: findings from secondary data analysis of Global Adult Tobacco Survey

OBJECTIVE

To quantify the extent of awareness regarding the harmful effects of tobacco among the users (both smoked and smokeless) and non-users in India, and explore the determinants of comprehensive knowledge among the participants of the Global Adult Tobacco Survey (GATS), India.

DESIGN

Cross-sectional study.

SETTING AND PARTICIPANTS

The nationally representative GATS I (2009-2010) included 69 296 participants using a multistage sampling method, while GATS II (2015-2016) interviewed 74 037 respondents aged >15 years using a similar sampling method from all the states and union territories in India.

PRIMARY AND SECONDARY OUTCOME MEASURES

Comprehensive score were derived from nine items that explored awareness regarding the adverse effects of tobacco use among both users and non-users of tobacco in GATS II. Secondary outcome included predictors of awareness regarding adverse effects of tobacco and changes in the awareness compared with the previous round of the survey.

RESULTS

About 60.2%, 57.5% and 66.5% of the smokers, smokeless tobacco (SLT) users and non-users were aware of the adverse effects of tobacco, respectively. The awareness depicted significant age, gender, marital status, education status, urban-rural, wealth and regional disparities (p<0.05). Intention to quit tobacco use also varied significantly with awareness. Among smokers, awareness was high in those residing in eastern India and the poorest participants. Among SLT users, awareness was more among male participants, those who were poorest and lived in western India. Among non-users, awareness was more among middle-aged, more educated, rich participants of west India. Compared with GATS I, an increase in awareness was observed in GATS II across gender, age groups, residential areas and geographical regions in India.

CONCLUSIONS

Comprehensive awareness of tobacco's harmful effects is far from desirable among Indian users. We recommend further customised health promotion campaigns to counter the regional disparities, adopt a gender-neutral approach and target adolescents.

Smokeless tobacco control in India: policy review and lessons for high-burden countries

We examined the magnitude of smokeless tobacco (SLT) use in India and identified policy gaps to ascertain the priorities for SLT control in India and other high SLT burden countries in the Southeast Asia region. We reviewed and analysed the legal and policy framework to identify policy gaps, options and priority areas to address the SLT burden in India and lessons thereof. In India, 21.4% adults, including 29.6% of men, 12.8% of women, use SLT while more than 0.35 million Indians die every year due to SLT use. SLT use remains a huge public health concern for other countries in the region as well. Priority areas for SLT control should include: constant monitoring, increasing taxes and price of SLT products, strengthening and strict enforcement of existing laws, integration of SLT cessation with all health and development programmes, banning of advertisement and promotion of SLT, increasing age of access to tobacco up to 21 years, introducing licensing for the sale of SLT, standardising of SLT packaging and preventing SLT industry interference in the implementation of SLT control policies besides a committed multistakeholder approach for effective policy formulation and enforcement. SLT control in India and the other high SLT burden countries, especially in the Southeast Asia region, should focus on strengthening and implementing the above policy priorities.

Stopping Smokeless Tobacco Use: A Call to Action

In the United States, single smokeless tobacco use continues to increase in conjunction with the dual use of smokeless tobacco and other nicotine products. Problematically, much of the tobacco prevention literature and funding inundates tobacco users with smoking tobacco information while neglecting to provide them any information about smokeless tobacco. Meanwhile, American tobacco companies continually market new and dissolvable tobacco products targeted at non-smokers. New data suggests that smokeless tobacco use is, also, increasing in West Virginia and, in order to address this increased use, the West Virginia Extension Service recently partnered with the Division of Tobacco Prevention in the West Virginia Department of Health and Human Resources to develop a comprehensive spit tobacco curriculum for West Virginia students between third and sixth grade. This article details the development and assessment of the spit tobacco prevention curriculum and the resulting report from the initial pilot of the program. The curriculum was piloted across six counties with the participation of schools, after-school programs and 4-H clubs. After implementation, survey results demonstrate that youth have increased awareness of the health effects of smokeless tobacco. Throughout the article, we explore West Virginia's Cooperative Extension Service's response to this emerging public health issue and release a call to action for the National Cooperative Extension Services to join us in spit tobacco prevention.

The Burden of Head and Neck Cancer in the United States, 1990 - 2017

PURPOSE

Head and neck cancers (HNC) are among the most common malignancies in the United States and are a significant cause of morbidity and mortality. Traditional risk factors for HNC include tobacco, alcohol, and Human Papilloma Virus (HPV) infection. Geographic location has also been shown to play a role, whether directly or indirectly. The purpose of this study was to describe the incidence, mortality and geographic variability of HNC within the United States between 1990 and 2017.

MATERIALS AND METHODS

The Global Burden of Diseases Study 2017, which models incidence and mortality, was used to obtain incidence and mortality data for "lip and oral cavity cancer", "nasopharynx cancer", "other pharynx cancer" (tonsil, oropharynx, and hypopharynx) and "larynx cancer" for the United States between 1990 and 2017.

RESULTS

The overall incidence rate of HNC increased (annual percent change (APC) = 0.23. 95% CI: 0.1-0.3) from 1990 through 2017 while overall mortality decreased (APC = -0.37. 95% CI: -0.4 to -0.3). The anatomic sub-site which saw the largest increase in incidence was "other pharynx" (APC=1.07. 95% CI: 0.9-1.2). In 2017, those in the West had the lowest incidence while those in the South had the highest (15.7 and 20.8 per 100,000 individuals, respectively).

CONCLUSIONS

The incidence of HNC in the United States increased between 1990 and 2017. This was driven by larger increases in those sites more prone to HPV-related HNC. While there exists geographic variability in the burden of this disease, additional studies are needed to further understand the impact of patient-specific factors.

COVID-19 and Smoking: What Evidence Needs Our Attention?

The current COVID-19 pandemic has caused severe morbidity and mortality worldwide. Although relevant studies show that the smoking rate of COVID-19 patients is relatively low, the current smoking status of people with COVID-19 cannot be accurately measured for reasons. Thus, it is difficult to assess the relationship between smoking and COVID-19. Smoking can increase the risk of severe COVID-19 symptoms and aggravate the condition of patients with COVID-19. Nicotine upregulates the expression of ACE2, which can also increase susceptibility to COVID-19, aggravatiing the disease. Although nicotine has certain anti-inflammatory effects, there is no evidence that it is related to COVID-19 treatment; therefore, smoking cannot be considered a preventative measure. Furthermore, smokers gathering and sharing tobacco may promote the spread of viruses. Despite the COVID-19 epidemic, the findings suggested that COVID-19 has not encouraged smokers to quit. Additionally, there is evidence that isolation at home has contributed to increased smoking behavior and increased quantities. Therefore, it is recommended that governments increase smoking cessation messaging as part of public health measures to contain the COVID-19 pandemic. This review analyzes the existing research on smoking's impact on COVID-19 so that governments and medical institutions can develop evidence-based smoking-related prevention and control measures for COVID-19.

Identification of Policy Priorities to Address the Burden of Smokeless Tobacco in Pakistan: A Multimethod Analysis

Introduction

We assessed the magnitude of smokeless tobacco (ST) use in Pakistan and identified policy gaps to help ascertain short-, medium-, and long-term priorities. We then elicited stakeholders’ views as to which of these identified priorities are most important.

Methods

In a multimethod study, we: analyzed Global Tobacco Surveillance System data sets to estimate ST consumption and disease burden; conducted a documentary review to identify gaps in policies to control ST in comparison with smoking; elicited stakeholders’ views in an interactive workshop to identify a set of policy options available to address ST burden in Pakistan; and ranked policy priorities using a postevent survey.

Results

Among all tobacco users in Pakistan (n = 24 million), one-third of men and two-thirds of women consume ST. In 2017, its use led to an estimated 18 711 deaths due to cancer and ischemic heart disease. Compared to smoking, policies to control ST lag behind significantly. Priority areas for ST policies included: banning ST sale to and by minors, advocacy campaigns, introduction of licensing, levying taxes on ST, and standardizing ST packaging. A clear commitment to close cooperation between state actors and stakeholder groups is needed to create a climate of support and information for effective policy making.

Conclusions

Smokeless tobacco control in Pakistan should focus on four key policy instruments: legislation, education, fiscal policies, and quit support. More research into the effectiveness of such policies is also needed.

Implications

A number of opportunities to improve ST regulation in Pakistan were identified. Among these, immediate priorities include banning ST sale to and by minors, mobilizing advocacy campaign, introduction of licensing through the 1958 Tobacco Vendors Act, levying taxes on ST, and standardizing ST packaging.

Looking beyond the smokescreen: can the oral microbiome be a tool or target in the management of tobacco-associated oral cancer?

A wide range of microbes inhabit the oral cavity, and bacterial and fungal communities most often exist as structured communities or biofilms. The use of tobacco alters the structure of the oral microbiome, including that of potentially malignant lesions, and the altered oral microbiome influences key microenvironmental changes such as chronic inflammation, secretion of carcinogenic toxins, cellular and tissue remodelling and suppression of apoptosis. Given this, it is clear that the bacterial and fungal biofilms in potentially malignant states are likely not passive entities, but could play a critical role in shaping potential malignant and carcinogenic conditions. This holds potential towards leveraging the oral microbiome for the management of tobacco-associated potentially malignant lesions and oral cancer. Here, we explore this line of investigation by reviewing the effects of tobacco in shaping the oral microbiome, and analyse the available evidence in the light of the microbiome of oral potentially malignant and cancerous lesions, and the role of dysbiosis in carcinogenesis. Finally, we discuss possible interventions and approaches using which the oral microbiome could be leveraged towards precision-based oral cancer therapeutics.

Prevalence and social determinants of tobacco use in Afghanistan

Background

Limited evidence exists on the prevalence and social determinants of tobacco use in Afghanistan—a fragile post-war context where the tobacco epidemic is on the rise. This study aimed to estimate the prevalence and social determinants of tobacco use in Afghan men and women.

Methods

Data from the 2015 Afghanistan Demographic and Health Survey of 10 760 men and 29 461 women were used to generate weighted prevalence estimates for smoking, smokeless tobacco (SLT) products including chew and snuff tobacco, ‘any tobacco use’ and ‘dual tobacco use’. We also modelled associations with tobacco outcomes using binary logistic regressions.

Results

We found that for men, smoking cigarettes was the most prevalent form of tobacco use (21.9% [95% confidence interval {CI} 21.2–22.7]). Prevalence rates were far lower for women, with cigarette/pipe smoking at 3.4% (95% CI 3.2–3.7). For both sexes, tobacco use was inversely associated with education and positively associated with agricultural and skilled and unskilled manual labour occupations. Wealth increased the odds of smoking for men but decreased the odds for women. Media exposure had little influence on tobacco use among women; however, the effects were more varied for men.

Conclusions

Our results demonstrate social inequalities in tobacco use among Afghan men and women, which calls for stronger tobacco control measures and continued monitoring of this growing epidemic.

Tobacco use as a well-recognized cause of severe COVID-19 manifestations

INTRODUCTION

The Coronavirus disease (COVID-19) infection is caused by the novel Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) primarily affecting the lungs. All tobacco-related illnesses including asthma, chronic obstructive pulmonary disease (COPD), and coronary artery disease are known to reduce the lung capacity and impair the immune system of the body and can greatly influence the ability to fight the novel coronavirus. The purpose of this state-of-the-art literature review is to summarize the evidence of the association of tobacco use with the severity of the COVID-19 manifestations.

METHOD

Articles describing the association of tobacco use with the severity of COVID-19 manifestations were searched on PubMed, MEDLINE, and Google. This review covers the relevant studies on the subject published from January 1, 2020 to September 10, 2020.

RESULTS

Tobacco use in all forms, whether smoking or chewing, is significantly associated with severe COVID-19 outcomes. Pre-existing comorbidities in tobacco users such as cardiovascular diseases, diabetes, respiratory diseases and hypertension were found to further aggravate the disease manifestations making the treatment of such COVID-19 patients more challenging due to their rapid clinical deterioration.

CONCLUSIONS

Current review indicates that nicotine exposure is linked to cardiopulmonary vulnerability to COVID-19 and tobacco use can be a potential risk factor for not only getting the viral infection but also its severe manifestations. The current pandemic provides a teachable moment to break the cycle of nicotine addiction and accelerate national tobacco control programs to achieve a tobacco-free world.

Global impact of tobacco control policies on smokeless tobacco use: a systematic review protocol

INTRODUCTION

Smokeless tobacco (ST) was consumed by 356 million people globally in 2017. Recent evidence shows that ST consumption is responsible for an estimated 652 494 all-cause deaths across the globe annually. The WHO Framework Convention on Tobacco Control (FCTC) was negotiated in 2003 and ratified in 2005 to implement effective tobacco control measures. While the policy measures enacted through various tobacco control laws have been effective in reducing the incidence and prevalence of smoking, the impact of ST-related policies (within WHO FCTC and beyond) on ST use is under-researched and not collated.

METHODS AND ANALYSIS

A systematic review will be conducted to collate all available ST-related policies implemented across various countries and assess their impact on ST use. The following databases will be searched: Medline, EMBASE, PsycINFO, Cumulative Index to Nursing and Allied Health Literature, Scopus, EconLit, ISI Web of Science, Cochrane Library (CENTRAL), African Index Medicus, LILACS, Scientific Electronic Library Online, Index Medicus for the Eastern Mediterranean Region, Index Medicus for South-East Asia Region, Western Pacific Region Index Medicus and WHO Library Database, as well as Google search engine and country-specific government websites. All ST-related policy documents (FCTC and non-FCTC) will be included. Results will be limited to literature published since 2005 in English and regional languages (Bengali, Hindi and Urdu). Two reviewers will independently employ two-stage screening to determine inclusion. The Effective Public Health Practice Project's 'Quality Assessment Tool for Quantitative Studies' will be used to record ratings of quality and risk of bias among studies selected for inclusion. Data will be extracted using a standardised form. Meta-analysis and narrative synthesis will be used.

ETHICS AND DISSEMINATION

Permission for ethics exemption of the review was obtained from the Centre for Chronic Disease Control's Institutional Ethics Committee, India (CCDC_IEC_06_2020; dated 16 April 2020). The results will be disseminated through publications in a peer-reviewed journal and will be presented in national and international conferences.

Factors Influencing Implementation of a Workplace Tobacco Cessation Intervention in India: A Qualitative Exploration

BACKGROUND

Tobacco use is projected to cause more than 8 million deaths annually worldwide by 2030 and is currently linked to 1 million annual deaths in India. Very few workplaces provide tobacco cessation as a part of occupational health in India. In this study, we examined promoters and barriers to implementing an evidence-based tobacco cessation program in a workplace setting in India.

METHODS

In-depth interviews were conducted with all facilitators (two program coordinators and four counselors) of a workplace tobacco cessation intervention covering implementation efforts in five organizations, including three manufacturing units and two corporate settings.

FINDINGS

The identified promoters for implementation of the program were as follows: (a) workplaces that provided access to many individuals, (b) high prevalence of tobacco use that made the intervention relevant, (c) core components (awareness sessions, face-to-face counseling and 6-months follow-up) that were adaptable, (d) engagement of the management in planning and execution of the intervention, (e) employees' support to each other to quit tobacco, (f) training the medical unit within the workplace to provide limited advice, and (g) efforts to advocate tobacco-free policies within the setting. Barriers centered around (a) lack of ownership from the workplace management, (b) schedules of counselors not matching with employees, (c) nonavailability of employees because of workload, and (d) lack of privacy for counseling.

CONCLUSION/IMPLICATIONS FOR PRACTICE

This study provided practical insights into the aspects of planning, engaging, executing and the process of implementation of a tobacco cessation intervention in a workplace setting. It provided guidance for an intervention within occupational health units in similar settings.

Relevance of Combined Electron and Photon Beams in Radiotherapy of Head and Neck Cancers in the Era of Intensity-Modulated Radiotherapy

Introduction External beam radiotherapy (EBRT) for head and neck (H&N) cancers continues to be delivered using varied technologies, ranging from the old two-dimensional conventional radiotherapy (2DRT) techniques to the modern three-dimensional conformal radiotherapy (3DCRT), intensity-modulated radiotherapy (IMRT), and volumetric modulated arc therapy (VMAT) in different centers in India. Due to limitations of spinal cord tolerance, electron and photon beams are combined in 2DRT and 3DCRT techniques for treating nodal volume of the H&N cases. However, many centers having modern technology practice IMRT/VMAT in place of electron beams. The purpose of this study is to analyze the role of combined electron and photon beams in radiotherapy of H&N cancers and its relevance in the modern era of IMRT/VMAT.

Materials and Methods Data were collected through a survey conducted on cancer centers in India where radiotherapy is being given by 2DRT, 3DCRT, and IMR/VMAT for the treatment of head and neck cancers.

Results The mean percentage of H&N (H&N) cases among all cases were 39.2% (standard deviation [SD]: 14.22), out of which 16.63% (SD: 20.83) were treated with a combination of photon and electron beams and 49.73% (SD: 37.41) were treated with IMRT/VMAT. The average percentage of H&N cases of government institutes was 38.39% (SD: 14.11) and that of private institutes was 40.14% (SD: 14.11). Patients treated with photon and electron combination and IMRT/VMAT were 22.19% (SD: 11.24) and 24.05% (SD: 23.99), respectively, in government institutes, and 10.29% (SD: 11.24) and 79.09% (SD: 26.75) in private institutes.

Conclusion As per this study, we conclude that despite the availability of IMRT/VMAT, a combination of electron and photon beams is still relevant in India. Since a large proportion of the patients are still treated with the electron and photon combination, it is imperative that further studies on field–junction dosimetry should be conducted to ensure accurate dose delivery.
