Prevalence of Smokeless Tobacco Use and Number of Users in 121 Countries.

Background: In 2010, a study estimated the number of smokeless tobacco (SLT) users in 70 countries at 302.4 million. These countries represented 70% of the global population. We aimed to update this information and widen the scope to estimate the global prevalence of SLT use by including a larger number of countries. Methods: Data on the prevalence of current SLT use in 121 countries were obtained from various sources. Country-wise and gender-wise breakdown of the adult population in these countries was derived from the UN World Population for 2015. To translate prevalence rates into an estimate of the number of adult SLT users, we multiplied the adult male and female SLT prevalence rates by the corresponding male and female adult population in the respective countries. We then added the estimated number of male and female SLT users to get an overall estimate of SLT use. Results: There were 352 million SLT users (351.9 million) in 121 countries. Of these, 67% were men (232.7 million) and 33% were women (119.2 million). Nearly 95% (333.1 million) of global SLT users lived in developing countries and only 5% (918.8 million) lived in developed countries; 82.7% of global SLT users lived in the World Health Organization (WHO) South-East Asia Region. Globally, 90.4% of SLT users live in 11 countries of the world: India (237.4 million, 67.5%), Bangladesh (30.9 million), Myanmar (12.6 million), Pakistan (10.1 million), USA (9.6 million), China (4.1 million), Indonesia (3.2 million), Nepal (2.7 million), Madagascar (2.6 million), Germany and Uzbekistan (2.4 million each). Conclusion: Smokeless tobacco use is a global epidemic affecting 121 countries. All 180 countries that have ratified the WHO Framework Convention on Tobacco Control (WHO FCTC) are obliged to monitor SLT use. Parties to the Convention should collect information periodically using standard protocols for national and international comparability. To prevent health and economic losses attributable to SLT use, countries, especially developing countries, should formulate strategies specific to SLT control.

Exposure to tobacco smoke among adults in Bangladesh.

Objective: To examine exposure to second-hand smoke (SHS) at home, in workplace, and in various public places in Bangladesh. Materials and Methods: Data from 2009 Global Adult Tobacco Survey (GATS) conducted in Bangladesh was analyzed. The data consists of 9,629 respondents from a nationally representative multi-stage probability sample of adults aged 15 years and above. Exposure to second-hand smoke was defined as respondents who reported being exposed to tobacco smoke in the following locations: Indoor workplaces, homes, government building or office, health care facilities, public transportation, schools, universities, restaurants, and cafes, coffee shops or tea houses. Exposure to tobacco smoke in these places was examined by gender across various socioeconomic and demographic sub-groups that include age, residence, education and wealth index using SPSS 17.0 for complex samples. Results: The study shows high prevalence of SHS exposure at home and in workplace and in public places. Exposure to SHS among adults was reported high at home (54.9%) (male-58.2% and female-51.7%), in workplace (63%) (male-67.8% and female-30.4%), and in any public place (57.8%) (male-90.4% and female-25.1%) 30 days preceding the survey. Among the public places examined exposure was low in the educational institutions (schools-4.3%) and health care facilities (5.8%); however, exposure was high in public transportation (26.3%), and restaurants (27.6%). SHS exposure levels at home, in workplace and public places were varied widely across various socioeconomic and demographic sub-groups. Conclusions: Exposure was reported high in settings having partial ban as compared to settings having a complete ban. Following the WHO FCTC and MPOWER measures, strengthening smoke-free legislation may further the efforts in Bangladesh towards creating and enforcing 100% smoke-free areas and educating the public about the dangers of SHS. Combining these efforts can have a complementary effect on protecting the people from hazardous effect of SHS as well as reducing the social acceptance of smoking both at home and in public and workplaces. Ongoing surveillance in Bangladesh is necessary to measure progress towards monitoring SHS exposure.

Smokeless tobacco: A major public health problem in the SEA region: A review.

Smokeless tobacco use is on the upswing in some parts of the world, including parts of SEAR. It is therefore important to monitor this problem and understand the possible consequences on public health. Material for this review was obtained from documents and data of the World Health Organization, co-authors, colleagues, and searches on key words in PubMed and on Google. Smokeless tobacco use in SEAR, as betel quid with tobacco, declined with increased marketing of cigarettes from the early twentieth century. Smokeless tobacco use began to increase in the 1970s in South Asia, with the marketing of new products made from areca nut and tobacco and convenient packaging. As a consequence, oral precancerous conditions and cancer incidence in young adults have increased significantly. Thailand's successful policies in reducing betel quid use through school health education from the 1920s and in preventing imports of smokeless tobacco products from 1992 are worth emulating by many SEAR countries. India, the largest manufacturing country of smokeless tobacco in the Region, is considering ways to regulate its production. Best practices require the simultaneous control of smokeless and smoking forms of tobacco. Governments in SEAR would do well to adopt strong measures now to control this problem.

WHO framework convention on tobacco control and its implementation in South-East Asia region.

The birth of the WHO Framework Convention on Tobacco Control (WHO FCTC) took place in response to the global tobacco epidemic and it became the most important global tobacco control instrument. Duly recognizing tobacco use as an important public health problem and in the wake of rising prevalence of and mortality related to tobacco use, almost all Member States of the South-East Asia Region signed and ratified the WHO FCTC. Following the ratification, Member countries have enacted comprehensive national tobacco control laws and regulations. Most countries have covered some important provisions, such as tax and price measures, smoke-free places, health warnings, a ban on tobacco advertising and promotion, and a ban on tobacco sales to minors. In spite of innumerable constraints and challenges, particularly human, infrastructural and financial resources, Member countries have been doing their best to enforce those legislations and regulations as effectively as possible. In order to educate the general public on the harmful effects of tobacco, mass health campaigns have been organized which are being continued and sustained. However, some of the important areas that need attention in due course of time are tax raises, illicit trade, tobacco industry interference and alternate cropping systems. All Member States in the Region are striving harder to achieving the goals and provisions of the Framework Convention through actively engaging all relevant sectors and addressing the tobacco issue holistically, and thus protecting the present and future generations from the devastating health, social, economic and environmental consequences of tobacco consumption and exposure to tobacco smoke.

Tobacco use among youth and adults in member countries of South-East Asia region: Review of findings from surveys under the global tobacco surveillance system.

Background: This paper examines the prevalence of current tobacco use among youth and adults in selected member countries of the South-East Asia Region using the data from school and household-based surveys included in the Global Tobacco Surveillance System. Materials and Methods: Global Youth Tobacco Survey (GYTS) data (years 2007-2009) were used to examine current tobacco use prevalence among youth, whereas Global Adult Tobacco Survey (GATS) data (years 2009-2010) were used to examine the prevalence among adults. GYTS is a school-based survey of students aged 13-15, using a two-stage cluster sample design, and GATS is a household survey of adults age 15 and above using a multi-stage stratified cluster design. Both surveys used a standard protocol for the questionnaire, data collection and analysis. Results: Prevalence of current tobacco use among students aged 13-15 varied from 5.9% in Bangladesh to 56.5% in Timor-Leste, and the prevalence among adults aged 15 and above was highest in Bangladesh (43.3%), followed by India (34.6%) and Thailand (27.2%). Reported prevalence was significantly higher among males than females for adults and youth in all countries except Bangladesh, Sri Lanka and Timor-Leste. Current use of tobacco other than manufactured cigarettes was notably higher than current cigarette smoking among youth aged 13-15 years in most countries of the Region, while the same was observed among adults in Bangladesh, India and Thailand, with most women in those countries, and 49% of men in India, using smokeless tobacco. Conclusion: Tobacco use among youth and adults in member countries of the region is high and the pattern of tobacco consumption is complex. Tobacco products other than cigarettes are commonly used by youth and adults, as those products are relatively cheaper than cigarettes and affordable for almost all segments of the population. As a result, use of locally produced smoked and smokeless tobacco products is high in the region. Generating reliable data on tobacco use and key tobacco control measures at regular intervals is essential to better understand and respond with effective tobacco control intervention.

Social, economic and legal dimensions of tobacco and its control in South-East Asia region.

This paper examines the social, cultural, economic and legal dimensions of tobacco control in the South-East Asia Region in a holistic view through the review of findings from various studies on prevalence, tobacco economics, poverty alleviation, women and tobacco and tobacco control laws and regulations. Methods were Literature review of peer reviewed publications, country reports, WHO publications, and reports of national and international meetings on tobacco and findings from national level surveys and studies. Tobacco use has been a social and cultural part of the people of South-East Asia Region. Survey findings show that 30% to 60% of men and 1.8% to 15.6% of women in the Region use one or the other forms of tobacco products. The complex nature of tobacco use with both smoking and smokeless forms is a major challenge for implementing tobacco control measures. Prevalence of tobacco use is high among the poor and the illiterate. It is higher among males than females but studies show a rising trend among girls and women due to intensive marketing of tobacco products by the tobacco industry. Tobacco users spend a huge percent of their income on tobacco which deprives them and their families of proper nutrition, good education and health care. Some studies of the Region show that cost of treatment of diseases attributable to tobacco use was more than double the revenue that governments received from tobacco taxation. Another challenge the Region faces is the application of uniform tax to all forms of tobacco, which will reduce not only the availability of tobacco products in the market but also control people switching over to cheaper tobacco products. Ten out of eleven countries are Parties to the WHO Framework Convention on Tobacco Control and nine countries have tobacco control legislation. Enforcement of control measures is weak, particularly in areas such as smoke-free environments, advertisement at the point of sale and sale of tobacco to minors. Socio-cultural acceptance of tobacco use is still a major challenge in tobacco control efforts for the governments and stakeholders in the South-East Asia Region. The myth that chewing tobacco is less harmful than smoking tobacco needs to be addressed with public awareness campaigns. Advocacy on the integration of tobacco control with poverty alleviation campaigns and development programs is urgently required. Law enforcement is a critical area to be strengthened and supported by WHO and the civil society organizations working in the area of tobacco control.

The relationship between tobacco advertisements and smoking status of youth in India.

OBJECTIVE: To examine the relationship between tobacco advertisements, counter-advertisements, and smoking status among Indian youth. MATERIALS AND METHODS: Global Youth Tobacco Survey (GYTS) data was used; the data encompassed a representative two-stage probability sample of 60,001 students aged 13-15 years in 24 states in India. These students were interviewed with an anonymous, self-administered questionnaire. Binary logistic regression analyses were performed with smoking status as the dependent variable, and exposure to cigarette advertisements or counter-advertisements as independent variables. RESULTS: Students watching anti-smoking media messages were less likely to be current smokers, which was true for both boys [OR = 0.89, 95% CI (0.81-0.98)] and girls [OR = 0.79, 95% CI (0.69-.90)]. This relationship was stronger among past smokers for boys [OR = 0.56, 95%CI (0.52-0.60)] and girls [OR = 0.49, 95% CI (0.45-0.53)]. On the other hand, students who were exposed to cigarette brand names during sports events and other televised programs, newspapers or magazines, and being offered free cigarette or cigarette-branded merchandise promotions were significantly more likely to be smokers, with effects ranging from moderate (OR=1.19) to very strong (OR=3.83). CONCLUSIONS: This is the first attempt from India to investigate the relationship between smoking and advertising. When the data were collected, cigarette advertising was legal and highly correlated with smoking behavior. Today, indirect surrogate advertising still exists; future research should examine its effect, as it is likely to have the same impact as direct advertising on smoking behavior. Finally, counter-advertising has a protective effect on youth and may function as a cessation aid.

School policy and tobacco use by students in Bihar, India.

The association between school tobacco policies and tobacco use prevalence among students were examined. A two stage cluster sample design with probability proportional to the enrolment in grades VIII-X was used. Comparison was made between schools with a tobacco policy (Federal schools) and schools without a policy (State schools). Stratified probability samples of 50 schools each were selected. SUDAAN and the C-sample procedure in Epi-Info was used for statistical analysis. Students from State schools (without tobacco policy) reported significantly higher ever and current any tobacco use, current smokeless tobacco use and current smoking compared to Federal schools (with tobacco policy) both in rural and urban areas. Classroom teaching on the harmful effects of tobacco was significantly higher (17-24 times) in Federal schools than State schools both in rural and urban areas. Parental tobacco use was similar for students in Federal and State schools. Students attending state schools were more likely than students attending Federal schools to have friends who smoke or chew tobacco. These findings suggest that the wider introduction of comprehensive school policies may help to reduce adolescent tobacco use.

Tobacco control practices by medical doctors in developing world; a questionnaire study.

AIM: To know about the tobacco control practices by medical doctors in Bihar, India. SETTINGS & DESIGN: All medical doctors in Bihar, India. Two stage sampling with probability propotional to the number of doctors in the districts was used. METHOD: Anonymous survey was conducted on structured questionnaire. STATISTICAL ANALYSIS: SUDAAN and Epi-Info. RESULTS: Most of the doctors were government doctors. Most doctors (>75%) reported either for no policy or partial policy in health settings however over 2/3rd of medical doctors felt need for their training on tobacco cessation. Most of the doctors did not take tobacco history (60-80%). CONCLUSION: Medical doctors in Bihar need to be trained for tobacco cessation. Smoking needs to be enforced vigorously in health sector to protect patients and doctors.

Tobacco use among teachers [corrected] in Uttar Pradesh & Uttaranchal, India.

Information about tobacco use prevalence, knowledge and attitude was assessed among school personnel in Uttar Pradesh. A single cluster sample design with probability proportional to the enrolment in grades 8-10 was used. Statistical analysis was done using SUDAAN and the C-sample procedure in Epi-Info. The school response rate was 100%. School personnel response rate ranged from 72-80%, the proportion of men being 84-92%. Current cigarette smoking and smokeless tobacco use reported by all teachers was 21.9% and 75.6% respectively. The prevalence of daily cigarette smoking was ranged by 12.6-15.1%; bidi and other smoking 4.8-13.4%; smokeless tobacco use 16.3-19.8%. Existing school policy on four measures were reported poor however over 72% school personnel felt need for policy prohibiting tobacco use among students and school personnel. Tobacco prevention instruction by teachers did not fare much better on six different measures (4.9-30.9%). However over 2/3rd school personnel were very supportive on tobacco control issues. There was no training among school personnel on tobacco use prevention skills (3.7%). However most of the school personnel (67.1%) were curious about getting such trainings. A positive environment for tobacco use prevention needs to be created by adopting comprehensive tobacco control policies for schools. First step towards this may be training of school personnel on tobacco use prevention skill and supply of teaching materials.

Tobacco control practices in 25 schools of West Bengal.

Information about tobacco use prevalence, knowledge and attitude was assessed among school personnel in schools of West Bengal. Statistical analysis was done using SUDAAN and the C-sample procedure in Epi-Info. The school response rate was 100%. Current any smoking and smokeless tobacco use was reported by 30.9% and 13.1% school personnel, respectively. Current daily smoking, and smokeless tobacco use reported by 20.4%, and 5.8% school personnel respectively. Men reported significantly more for all kinds of daily tobacco use as compared to women. School tobacco control policy on three scales was reported poor (17.7-30%). However most of the school personnel felt need for such policies (82.7-93.6%). Teaching and training on tobacco was reported low (29.9%-50.4%). However most of the school personnel (79.1-93.6%) were supportive on different measures of tobacco control. Training of school personnel may provide students with essential tools to help them adopt and maintain a smoke free lifestyle.

Effectiveness of tobacco cessation intervention programs.

A study was conducted in selected districts of Bihar to evaluate the effectiveness of Intensive vs. Minimal, Community centered vs. Clinic/Camp centered and Mass/Group vs. Individual targeted intervention programs for cessation of tobacco use. Relevant Qualitative and Quantitative data was collected and analyzed using the SPSS statistical package. Results revealed high (>50%) pre-intervention prevalence of tobacco use and oral diseases related to tobacco usage and no community initiative towards control of tobacco use. Post intervention data revealed 4% quitting, 3% dose reduction and 2% reduction in usage of multiple types of tobacco. The study demonstrated that community centered mass approaches with minimal sustained intervention was more effective than clinic centered, intensive, individual approach.

Tobacco use among students in Bihar (India).

Determination of the prevalence and attitudes toward tobacco use was assessed among 13-15 years school students in Bihar (India). Settings and design: Schools having grade 8-10 in Bihar. A two stage cluster sample design was used. SUDAAN and the C-sample procedure in Epi-Info was used for statistical analysis. Of the 2636 respondents, 71.8% (76.5% boys, 57.2% girls) were ever tobacco users; of them 48.9% had used tobacco before 10 years of age. Current use was reported by 58.9% (Boys 61.4%, Girls 51.2%); smokeless tobacco by 55.6% (Boys 57.6%, Girls 49.2%); and smoking by 19.4% (23.0% boys, 7.8% girls). Nearly one third (29%) students were exposed to ETS inside their homes and nearly half (48%) outside their homes. Almost all students reported watching cigarette and gutka advertisements in almost all kinds of media and events. Tobacco use by parents and friends, knowledge on harmful effects of chewing tobacco, smoking and environmental smoke, and attitudes on tobacco use by others were strongly associated with student tobacco use. Current tobacco use was reported significantly more by students who received pocket money/or were earning than by students who did not receive any pocket money/or did not earn (p value for trend <0.0001). Over half of current users (56%) bought their tobacco products from stores; of these, over 3/4th (77.2%) of them despite their age, had no difficulty in procuring these products. Teaching in schools regarding harmful effects of tobacco use was non-existent (3%). This urgently requires a comprehensive prevention program in schools and the community especially targeted towards girls.

Tobacco use among school personnel in Orissa.

Tobacco use prevalence, knowledge and attitude was assessed among school personnel in Orissa. A single cluster sample design with probability proportional to the enrolment in grades VIII-X was used. Statistical analysis was clone using SUDAAN and the C-sample procedure in Epi-Info. The school response rate was 100%. Over 72% of school personals participated in the survey, the proportion of men being 84%. Current cigarette smoking, bidi smoking and smokeless tobacco use was reported by 26.8%, 30.1% and 38.8% school personnel respectively. Current daily cigarette smoking, bidi smoking and smokeless tobacco use reported by 18.3%, 16.6% and 24.2% school personnel respectively. Men reported significantly more all kinds of daily tobacco use as compared to women. School tobacco control policy on three scales was reported poor (25-39%). However most of the school personnel felt need for such policies (88-98%). Teaching and training on tobacco was reported low (22.7%-35.9%). Most of the school personnel (87-95%) were supportive on different measures on tobacco control issues. Introduction of comprehensive school policies and enforcement on tobacco use may help to reduce adolescent and school personnel tobacco use.
