Results of the Global Youth Tobacco Survey and implementation of the WHO Framework Convention on Tobacco Control in the WHO Eastern Mediterranean Region (EMR) countries

Awareness of tobacco industry tactics among tobacco control communities in Thailand and its association with attitudes towards tobacco industry and perceptions of e-cigarettes

BACKGROUND

Tobacco industry denormalisation is a key strategy recommended by the WHO Framework Convention on Tobacco Control as it is associated with reducing smoking behaviours and positively influencing public and policymakers' opinion towards tobacco control. However, studies of awareness of tobacco industry tactics among public health players and policymakers in low-income and middle-income countries are limited.

METHODS

We conducted an online survey of individuals who had been involved in tobacco control in Thailand. Multivariate ordinal logistic regression analysis was used to determine the association between awareness of tobacco industry tactics and different attitudes towards tobacco industry and perceptions towards e-cigarettes, controlling for role in tobacco control and demographics among 441 respondents.

RESULTS

Of the respondents, 11.3% had never heard of any tobacco industry tactics, whereas 11.1% had heard of all tactics asked in the survey. Tobacco industry tactics which were less known by participants were intimidation (30.6%) and illicit trade (37.4%). Participants who were more aware of tobacco industry tactics were more likely to have negative attitudes towards the tobacco industry and e-cigarettes. Compared with active experts of the Provincial Tobacco Products Control Committee and provincial public health officials who work in tobacco control programmes, advocates who worked for civil society organisations in tobacco control were more aware of tobacco industry tactics and had less favourable perceptions of e-cigarettes.

CONCLUSION

This study emphasises the importance of educating public health professionals and policymakers about tobacco industry behaviour, especially in the era of e-cigarettes.

Cancer Burden Variations and Convergences in Globalization: A Comparative Study on the Tracheal, Bronchus, and Lung (TBL) and Liver Cancer Burdens Among WHO Regions from 1990 to 2019

Lung cancer and liver cancer are the leading and third causes of cancer death, respectively. Both lung and liver cancer are with clear major risk factors. A thorough understanding of their burdens in the context of globalization, especially the convergences and variations among WHO regions, is useful in precision cancer prevention worldwide and understanding the changing epidemiological trends with the expanding globalization. The Global Burden of Disease (GBD) and WHO Global Health Observatory (GHO) database were analyzed to evaluate the burden metrics and risk factors of trachea, bronchus, and lung (TBL) cancer and liver cancer. Western Pacific Region (WPR) had the highest age-standardized incidence rate (ASIR) for both liver cancer (11.02 [9.62-12.61] per 100,000 population) and TBL cancer (38.82 [33.63-44.04] per 100,000 population) in 2019. Disability-adjusted life years (DALYs) for liver and TBL cancer elevated with the increasing sociodemographic index (SDI) level, except for liver cancer in WPR and TBL cancer in European Region (EUR). Region of the Americas (AMR) showed the biggest upward trends of liver cancer age-standardized rates (ASRs), as well as the biggest downward trends of TBL cancer ASRs, followed by Eastern Mediterranean Region (EMR). Alcohol use and smoking were the leading cause of liver and TBL cancer death in most WHO regions. Variances of ASRs for liver and TBL cancer among WHO memberships have been decreasing during the past decade. The homogenization and convergence of cancer burdens were also demonstrated in different agegroups and sexes and in the evolution of associated risk factors and etiology. In conclusion, our study reflects the variations and convergences in the liver and lung cancer burdens among the WHO regions with the developing globalization, which suggests that we need to be acutely aware of the global homogeneity of the disease burden that accompanies increasing globalization, including the global convergences in various populations, risk factors, and burden metrics.

Partially Hydrolyzed Guar Gum Intake Supports the Gut Microbiota and Attenuates Inflammation during Influenza H1N1 Virus Infection in Mice

Partially hydrolyzed guar gum (PHGG) is a soluble dietary fiber that is effective for defecation control. It influences the gut microbiota, by which it is metabolized to yield short-chain fatty acids (SCFAs), and it was also recently shown to protect against influenza infection in humans. We here investigated the effects of PHGG in a mouse model of influenza H1N1 virus infection. Eight-week-old C57BL/6 mice were fed normal chow with or without PHGG (500 mg/kg per day) for 4 weeks, infected with H1N1 at 10 weeks of age, and analyzed at 12 weeks of age. Administration of PHGG attenuated the decline in body weight induced by H1N1 infection without affecting food intake. It also ameliorated intestinal atrophy and increased the production of SCFAs including acetic acid, propionic acid, and butyric acid in the cecum, thereby preventing the inhibitory effect of H1N1 infection on SCFA production. The H1N1-induced increases in the serum concentrations of inflammatory cytokines including interferon-γ and interleukin-6 and anti-inflammatory cytokine such as interleukin-10 were all inhibited by PHGG intake. In addition, PHGG administration attenuated inflammatory gene expression in the lung and promoted both natural killer cell activity and regulatory T-cell differentiation in the spleen. Our findings suggest that the consumption of PHGG may improve the gut environment and thereby limit the inflammatory response to H1N1 infection. They may thus provide the basis for novel dietary intervention strategies to suppress the excessive inflammation associated with virus infection.

From the international tobacco control arena to the local context: a qualitative study on the tobacco advertising, promotion and sponsorship legislative environment in Sudan and the challenges characterising it

OBJECTIVES

The aim of the study was to assess the Sudanese tobacco advertising, promotion and sponsorship (TAPS) legislative environment and the challenges characterising it. We formulated three research questions: What is the TAPS policy context in Sudan? What circumstances led to the development of the current legislative text? Finally, what was the involvement of the different actors in these events?

DESIGN

We conducted a qualitative analysis using the Health Policy Triangle model to frame the collection and extraction of publicly available information from academic literature search engines, news media databases or websites of national and international organisations, as published by February 2021. The thematic framework approach was employed to code and analyse the textual data and the generated themes were used to map connections across the data and to explore relationships among the generated subthemes and themes.

SETTING

Sudan.

DATA

Using a combination of the keywords "Sudan" and "tobacco advertising" (or "tobacco marketing" or "tobacco promotion"), we collected publicly available documents in the English language. We included 29 documents in the analysis.

RESULTS

Three themes underpin the Sudanese legislative environment on TAPS: (1) limited and outdated TAPS data, (2) stakeholder involvement and tobacco industry interference and (3) TAPS legislation not aligned with the WHO Framework Convention on Tobacco Control Secretariat recommendations.

CONCLUSIONS

Findings from this qualitative analysis suggest that recommendations to move forward in Sudan should include the systematic and periodic collection of TAPS surveillance data, addressing any remaining legislative content loopholes and protecting policy-making from tobacco industry interference. In addition, best practices from other low-income and middle-income countries with good TAPS monitoring systems, such as Egypt, Bangladesh and Indonesia, or with protective provisions against tobacco industry interference, such as Thailand and the Philippines, could be considered for adaptation and implementation.

The global impact of tobacco control policies on smokeless tobacco use: a systematic review

BACKGROUND

Smokeless tobacco, used by more than 300 million people globally, results in substantial morbidity and mortality. For smokeless tobacco control, many countries have adopted policies beyond the WHO Framework Convention on Tobacco Control, which has been instrumental in reducing smoking prevalence. The impact of these policies (within and outside the Framework Convention on Tobacco Control) on smokeless tobacco use remains unclear. We aimed to systematically review policies that are relevant to smokeless tobacco and its context and investigate their impact on smokeless tobacco use.

METHODS

In this systematic review, we searched 11 electronic databases and grey literature between Jan 1, 2005, and Sept 20, 2021, in English and key south Asian languages, to summarise smokeless tobacco policies and their impact. Inclusion criteria were all types of studies on smokeless tobacco users that mentioned any smokeless tobacco relevant policies since 2005, except systematic reviews. Policies issued by organisations or private institutions were excluded as well as studies on e-cigarettes and Electronic Nicotine Delivery System except where harm reduction or switching were evaluated as a tobacco cessation strategy. Two reviewers independently screened articles, and data were extracted after standardisation. Quality of studies was appraised using the Effective Public Health Practice Project's Quality Assessment Tool. Outcomes for impact assessment included smokeless tobacco prevalence, uptake, cessation, and health effects. Due to substantial heterogeneity in the descriptions of policies and outcomes, data were descriptively and narratively synthesised. This systematic review was registered in PROSPERO (CRD42020191946).

FINDINGS

14 317 records were identified, of which 252 eligible studies were included as describing smokeless tobacco policies. 57 countries had policies targeting smokeless tobacco, of which 17 had policies outside the Framework Convention on Tobacco Control for smokeless tobacco (eg, spitting bans). 18 studies evaluated the impact, which were of variable quality (six strong, seven moderate, and five weak) and reported mainly on prevalence of smokeless tobacco use. The body of work evaluating policy initiatives based on the Framework Convention on Tobacco Control found that these initiatives were associated with reductions in smokeless tobacco prevalence of between 4·4% and 30·3% for taxation and 22·2% and 70·9% for multifaceted policies. Two studies evaluating the non-Framework policy of sales bans reported significant reductions in smokeless tobacco sale (6·4%) and use (combined sex 17·6%); one study, however, reported an increased trend in smokeless tobacco use in the youth after a total sales ban, likely due to cross-border smuggling. The one study reporting on cessation found a 13·3% increase in quit attempts in individuals exposed (47·5%) to Framework Convention on Tobacco Control policy: education, communication, training, and public awareness, compared with non-exposed (34·2%).

INTERPRETATION

Many countries have implemented smokeless tobacco control policies, including those that extend beyond the Framework Convention on Tobacco Control. The available evidence suggests that taxation and multifaceted policy initiatives are associated with meaningful reductions in smokeless tobacco use.

Youth susceptibility to tobacco use in the Gulf Cooperation Council Countries, 2001–2018

•

Analysis of the susceptibility to initiating tobacco use identifies youth at higher risk of initiating tobacco.

•

Susceptibility to initiate tobacco use in increased in the United Arab Emirates while decreased in Bahrain and Qatar.

•

FCTC may have an independent impact on initiating tobacco use among youth.

•

The study helps policymakers identify impactful policies and prioritize resources accordingly.

The Gulf Cooperation Council (GCC) countries – Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, and the United Arab Emirates (UAE) – ratified the Framework Convention on Tobacco Control (FCTC) in 2006. Yet, GCC countries predict a slight reduction in tobacco use compared to the Eastern Mediterranean region’s significant downward trend. The purpose of this study was to examine changes in self-reported intention to initiating tobacco use (susceptibility) among youth over time in five GCC countries and the relationship between susceptibility and key FCTC provisions. Complex sample logistic regression analyses were conducted using data from the 2001 to 2018 Global Youth Tobacco Survey (n = 349,878 adolescents). Since the ratification of FCTC in GCC countries, susceptibility to initiate tobacco use significantly decreased in Bahrain and Qatar while it increased in UAE (P < 0.001). Exposure to smoking in public places increased the odds of susceptibility to tobacco use in Bahrain (AOR = 1.6, 95% CI = [1.2–2.2), Kuwait (AOR = 1.6, 95% CI = [1.2–2.0]), Qatar (AOR = 1.9, 95% CI = [1.4–2.6]), and UAE (AOR = 2.1, 95% CI = [1.6–2.7]). Susceptibility to tobacco use was significantly associated with exposure to tobacco imagery in media in the UAE (AOR = 1.7, 95% CI = [1.2–2.3]) and with tobacco industry activities like promotion in Bahrain (AOR = 2.8, 95% CI = [1.9–4.2]) and Kuwait (AOR = 2.2, 95% CI = [1.5–3.1]). In conclusion, the impact of FCTC provisions on tobacco use differs across countries. Findings suggested that the implementation of tobacco control policies may independently influence the initiation of tobacco use.

Vitamins and other immune-supportive elements as cofactors for passing the COVID-19 pandemic

BACKGROUND

Coronavirus disease 2019 (COVID-19) is a viral disease that causes a respiratory disorder, started in December of 2019 in China. Several vitamins and trace elements could help in enhancing host immunity producing antioxidant or anti-inflammatory action. This work aimed to identify the role of different nutrition, vitamins, and trace elements on the immunity status of the infected subject and the possibility of the beneficial role of these elements in the management of COVID-19.

MAIN BODY

After collecting (PubMed, scholar, OVID, Embase, Cochrane Library) and investigating published articles, testing the effect of these elements on viral infection, it was found that most of these elements have a significant role during viral infection through a different mechanism, like antioxidant, anti-inflammatory, and immunomodulation. Nutritional interventions in COVID-19 infections are very important currently, and it was reported that vitamin C and D reduce the risk of acute respiratory infections. In addition, low vitamin A diets compromise the effectiveness of inactivated bovine coronavirus vaccines. Administration of N-acetyl cysteine showed a beneficial inhibitory effect in viral infections and enhanced glutathione production. The deficiency of selenium on COVID-19 subjects has a significant impact on the clinical outcome of the subjects. In addition, supplementation with vitamins proved to enhance immune response during viral infection. Vitamins and trace elements not only showed a beneficial effect but also Omega 3 fatty acids showed an immunomodulating effect during infections.

SHORT CONCLUSIONS

Assessment of levels for these trace elements at the baseline and providing supplementation containing different vitamins and elements could result in better control and clinical outcomes in the case of COVID-19.

Prevalence and determinants of current cigarette smoking and secondhand smoking among Greek adolescents: the Global Youth Tobacco Survey (GYTS) 2013 study

OBJECTIVES

Smoking prevalence in Greece is considered high within the European Union and the collection of evidence on tobacco use among adolescents is of vital importance in order to develop effective smoking prevention and cessation programmes.

DESIGN

Cross-sectional.

SETTING

Greece.

PRIMARY AND SECONDARY OUTCOME MEASURES

Global Youth Tobacco Survey (GYTS) is a national representative, paper-and-pencil, cross-sectional, school-based study of students at ages 13-15 years. The survey employed a multistage cluster sample design with schools selected proportional to enrolment size. Finally, 4618/5127 students aged 13-15 years participated in the survey. The school response rate was 98.1%, the student response rate was 90.1% and the overall response rate was 88.4%.

RESULTS

The prevalence of current cigarette smoking was estimated at 10.1% (10.4% in GYTS 2005) and of exposure to secondhand smoking in public places at 67.4% (94.1% in GYTS 2005). The vast majority of the adolescents (82.1%) supported the banning of smoking inside enclosed public places. Most of the current smokers (90.8%) were not prevented/refused purchase because of their age according to existing law. Multivariate analysis showed that peer influence (OR=48.32; 95% CI 36.2 to 64.48), pocket money (OR=2.63; 95% CI 1.28 to 3.41), increasing age (OR=2.35; 95% CI 1.63 to 3.39) and low educational level of father (OR=2.82; 95% CI 1.7 to 4.68) were risk factors independently associated with current cigarette smoking.

CONCLUSIONS

Despite the existence of strict laws related to tobacco control, exposure to secondhand smoking among Greek students remained high even when compared with GYTS in 2005. This is likely a result of weak enforcement, what is really missing is the enforcement of the related legislation.

Evolution of attitudes, trends and perceptions of smoking among middle and secondary school students in the Gharb Region, Morocco, 2010-2015

Background

Tobacco use is an important public health issue. Morocco implemented a tobacco control programme, which has been ongoing among students at middle and secondary schools since 2010.

Aim

This study aims to compare the trend in smoking among the programme beneficiaries with the results of the initial study conducted prior to the implementation of the programme.

Setting

This study was conducted in middle and secondary schools of the Gharb Region in Morocco between 2010 and 2015.

Methods

Two cross-sectional studies were conducted in 2010 and 2015 in the middle and secondary schools of the Gharb Region. Multistage cluster sampling was used. The information was collected using a self-administered questionnaire.

Results

In the first study in 2010, 5312 students participated, and in the second one in 2015, 4208 students participated. The level of information on smoking and its effects was higher in 2015 (94.0%) than in 2010 (92.5%). In 2010, parents, primary schools and television and radio were more involved in student information on smoking compared to 2015. The proportion of students claiming that tobacco was not a pleasure (86.3%) and that it does not calm nerves (76.5%) was significantly higher in 2015 than in 2010. The prevalence of smoking increased significantly in 2015 (2.9%) against 2010 (1.8%).

Conclusion

This study reports the general positive evolution in knowledge about smoking and its effects. Despite that the prevalence of smokers increased in 2015. The results suggest the need to address family influences on adolescent smoking and to investigate participation of schools in education and training students in tobacco dependence prevention.

Health risk behaviours of Palestinian youth: findings from a representative survey

BACKGROUND

There is little systematic information about health risk behaviours among youth in Middle Eastern countries, leaving public health authorities unprepared to deal with emerging public health threats at a time of major social change.

AIM

The Palestinian Youth Health Risk study investigates patterns of risk behaviours among Palestinian youth, their perceptions of the risks and benefits of such behaviours, and the relationship of exposure to violence with mental health and engagement in risk behaviours.

METHODS

We conducted a representative survey among 2500 individuals aged 15-24 years in the West Bank and East Jerusalem, permitting reliable comparison across sex and rural-urban divisions. A stratified 2-stage random sample was drawn from the 2007 population census, with strata formed by crossing the 12 governorates with urban, rural and refugee camp locations. Within strata, 208 survey clusters were sampled with probability proportional to size. Within each cluster, 14 households with youth of the appropriate age were sampled.

RESULTS

Among youth aged 20-24 years, 22.4% of males and 11.6% of females reported trying alcohol; 10.5% of males and 4.3% of females reported trying drugs. Almost one quarter of unmarried youth aged 20-24 years reported any sexual experience. Tobacco use is high, even among younger youth (45.4% of males and 21.2% of females aged 15-19 smoke). Risk behaviours are higher among males, older youth and in urban areas and refugee camps.

CONCLUSION

While smoking is of particular concern, prevention outreach for all behaviours should be directed at subgroups and areas identified as highest risk.

Burden of lower respiratory infections in the Eastern Mediterranean Region between 1990 and 2015: findings from the Global Burden of Disease 2015 study

OBJECTIVES

We used data from the Global Burden of Disease 2015 study (GBD) to calculate the burden of lower respiratory infections (LRIs) in the 22 countries of the Eastern Mediterranean Region (EMR) from 1990 to 2015.

METHODS

We conducted a systematic analysis of mortality and morbidity data for LRI and its specific etiologic factors, including pneumococcus, Haemophilus influenzae type b, Respiratory syncytial virus, and influenza virus. We used modeling methods to estimate incidence, deaths, and disability-adjusted life-years (DALYs). We calculated burden attributable to known risk factors for LRI.

RESULTS

In 2015, LRIs were the fourth-leading cause of DALYs, causing 11,098,243 (95% UI 9,857,095-12,396,566) DALYs and 191,114 (95% UI 170,934-210,705) deaths. The LRI DALY rates were higher than global estimates in 2015. The highest and lowest age-standardized rates of DALYs were observed in Somalia and Lebanon, respectively. Undernutrition in childhood and ambient particulate matter air pollution in the elderly were the main risk factors.

CONCLUSIONS

Our findings call for public health strategies to reduce the level of risk factors in each age group, especially vulnerable child and elderly populations.

Use of Electronic Nicotine Delivery Systems Among Adolescents: Status of the Evidence and Public Health Recommendations

Although the prevalence of tobacco smoking has been declining in recent years, the use of electronic nicotine delivery systems (ENDS) such as of electronic cigarettes, vaporizers, and hookahs has been steadily rising, especially among adolescents. ENDS are not only advertised to children, but their sale via the Internet has made them easily accessible to youth. In general, children perceive ENDS as safe, or at least safer than smoking traditional combustible tobacco products; however, exposure to nicotine may have deleterious effects on the developing brain. Concern also persists that ENDS may be a "starter" drug that may lead to further tobacco, drug, and/or alcohol use. In contrast to this precautionary stance that is associated with calls for legislative oversight of ENDS marketing and sales, harm reductionists claim that the risks posed by ENDS are minor in comparison with those of combustible tobacco products and that ENDS may be used as a means of nicotine replacement for smoking cessation, despite no concrete evidence to support this assertion. Many medical and health-related organizations have produced position statements concerning ENDS use, including among adolescents. This article summarizes the advantages and disadvantages of using ENDS espoused in these position statements, especially as they relate to use among adolescents. [Pediatr Ann. 2017;46(2):e69-e77.].

Uncovering risky behaviors of expatriate teenagers in the United Arab Emirates: A survey of tobacco use, nutrition and physical activity habits

Background

Tobacco use and unhealthy lifestyle habits amongst youth contribute to most major health issues in the United Arab Emirates (UAE) and worldwide. However up to date and comprehensive statistics are not available on the current behavior, experimentation and environmental influences on teenagers in the UAE’s expatriate community, who are greatly impacted by the country’s culture and environment, as well as bringing influences from their cultures of origin. Expatriates comprise a majority of the UAE population, making them an important subset of the population to study.

Method

To address this gap in knowledge, a survey was conducted to collect information on tobacco use, physical activity and nutrition behaviors, anti-tobacco media/legislation effectiveness and health education gaps.

Results

Our results provide a summary on each of these topics with regards to ninth grade expatriates in the UAE. We offer the first statistics on dokha use in this age group and uncover signs of underlying eating disorders.

Conclusions

In conclusion, we call for a tobacco use, nutrition and physical activity intervention targeted at this age group of UAE expatriates.

Tobacco use among designated air pollution victims and its association with lung function and respiratory symptoms: a retrospective cross-sectional study

OBJECTIVES

We sought to elucidate the long-term association of tobacco use and respiratory health in designated pollution victims with and without obstructive pulmonary defects.

DESIGN

A retrospective cross-sectional study.

SETTING

The register of pollution victims in Kurashiki, Japan.

PARTICIPANTS

730 individuals over 65 years of age previously diagnosed with pollution-related respiratory disease. Patients were classified into four groups according to their smoking status and whether they had obstructive pulmonary disease. We then compared the prevalence of respiratory symptoms and lung function over time between groups.

PRIMARY OUTCOME MEASURES

Spirometry was performed and a respiratory health questionnaire completed in the same season each year for up to 30 years.

RESULTS

Rates of smoking and respiratory disease were high in our sample. Although respiratory function in non-smoking patients did not completely recover, the annual rate of change in lung function was within the normal range (p<0.01). However, smokers had worse lung function and were more likely to report more severe pulmonary symptoms (p<0.01).

CONCLUSIONS

Patients' respiratory function did not fully recover despite improved air quality. Our results suggest that, in the context of exposure to air pollution, tobacco use causes additional loss of lung function and exacerbates respiratory symptoms.
