Prevalence Of Current Tobacco Smoking Research Articles

Current Tobacco Smoking and Desire to Quit Smoking Among Students Aged 13-15 Years - Global Youth Tobacco Survey, 61 Countries, 2012-2015.

Tobacco use is the world's leading cause of preventable morbidity and mortality, resulting in nearly 6 million deaths each year (1). Smoked tobacco products, such as cigarettes and cigars, are the most common form of tobacco consumed worldwide (2), and most tobacco smokers begin smoking during adolescence (3). The health benefits of quitting are greater for persons who stop smoking at earlier ages; however, quitting smoking at any age has health benefits (4). CDC used the Global Youth Tobacco Survey (GYTS) data from 61 countries across the six World Health Organization (WHO) regions from 2012 to 2015 to examine the prevalence of current tobacco smoking and desire to quit smoking among students aged 13-15 years. Across all 61 countries, the median current tobacco smoking prevalence among students aged 13-15 years was 10.7% (range=1.7%, Sri Lanka to 35.0%, Timor-Leste). By sex, the median current tobacco smoking prevalence was 14.6% among males (range=2.9%, Tajikistan to 61.4%, Timor-Leste) and 7.5% among females (range=1.6%, Tajikistan to 29.0%, Bulgaria). In the majority of countries assessed, the proportion of current tobacco smokers who desired to quit smoking exceeded 50%. These findings could be used by country level tobacco control programs to inform strategies to prevent and reduce youth tobacco use (1,4).

Geographical Inequality in Tobacco Control in China: Multilevel Evidence From 98 058 Participants.

We investigated the spatial patterning and correlates of tobacco smoking, exposure to secondhand smoke, smoking in public places, workplace smoking prohibition, pro- and counter-tobacco advertisements in mainland China. Choropleth maps and multilevel models were used to assess geographical variation and correlates of the aforementioned outcome variables for 98 058 participants across 31 provinces of China in 2010. Current tobacco smoking prevalence was higher in the central provinces for men and in the north eastern provinces and Tibet for women. Secondhand smoke was higher for both genders in Qinghai and Hunan provinces. Workplace tobacco restrictions was higher in the north and east, whereas smoking in public places was more common in the west, central, and far northeast. Protobacco advertising was observed in public places more often by men (18.5%) than women (13.1%). Men (35.5%) were also more likely to sight counter-tobacco advertising in public places than women (30.1%). Awareness of workplace tobacco restrictions was more common in affluent urban areas. Lower awareness of workplace tobacco restrictions was in less affluent urban and rural areas. Sightings of tobacco smoking in public places was highest in restaurants (80.4% for men, 75.0% for women) and also commonly reported in less affluent urban and rural areas. Exposure to secondhand smoke was lower among women (but not men) where workplace tobacco restrictions was more common and higher regardless of gender in areas where smoking in public places was more commonly observed. Geographical and gender-sensitive targeting of tobacco prevention and control initiatives are warranted. This study demonstrates spatial patterning of China's 300 million smokers across the country that are different for men and women. Many of the factors that influence tobacco use, such as pro- and counter-advertising, also vary geographically. Workplace smoking restrictions are more commonly reported among individuals with higher educational attainment, but this not does appear to translate into reduced exposure to secondhand smoke. There is a need to intervene in other contexts, especially in restaurants and on public transport. Geographically targeted and gender-sensitive policy is required to advance effective tobacco control and prevention of noncommunicable diseases across all of China.

Evaluation of the prevalence of waterpipe tobacco smoking and its related factors in Tehran, Islamic Republic of Iran.

This study is designed to evaluate the prevalence of waterpipe tobacco smoking and its related factors among Iranian adults. This is a cross-sectional study carried out during 2013/14 in Tehran, Islamic Republic of Iran, among 1830 citizens aged over 15 years. Sampling was through Stratified multistage cluster sampling with proportional allocation within strata. Global Adult Tobacco Survey (GATS) questionnaire for waterpipe consumption was used for data gathering. Data were statistically analyzed by SPSS software. The prevalence of current waterpipe tobacco smoking was 17.6% .Waterpipe use prevalence in men was significantly more than women (24.2% vs. 11.3%). Multivariate analysis showed that age, sex, cigarette consumption, waterpipe consumption at home and ignorance of safety issues significantly influenced current waterpipe smoking (P = 0.001). Thus, prevalence of waterpipe smoking in Iranian adults is high and significant. Tackling waterpipe smoking should be considered in tobacco control programmes. However, further studies in this field are needed.

Prevalence of Tobacco Smoking and Factors Associated with the Initiation of Smoking among University Students in Dhaka, Bangladesh.

Tobacco smoking is considered to be the key preventable risk factor for morbidity and mortality at the global level. The aim of this study was to determine the prevalence of tobacco smoking and factors associated with the initiation of smoking among university students in Dhaka, Bangladesh. A cross-sectional survey study was conducted with 264 students of Jahangirnagar University, Dhaka, Bangladesh in 2015. A standard, self-administered questionnaire consisting of questions on socio-demographic variables, tobacco smoking status, family and peer tobacco smoking history, attitudes and beliefs about tobacco smoking, as well as knowledge about the negative health consequences of tobacco smoking was administered to participants. Data were analyzed using logistic regression models, chi square, and Fisher exact tests. The overall prevalence of tobacco smoking was 60.2%, where males smoked at higher rates than females (68.81% and 19.56%, respectively). The influence of friends was the most significant reason for initiating tobacco smoking (OR: 0.862; CI: 0.810-0.917). Perception regarding tobacco smoking was significantly related to continuing tobacco use. Logistic regression models identified that smoking-related attitudes, potential health problems, and family members dying from cardiovascular disease and cancer were significantly associated with tobacco smoking. The current tobacco smoking prevalence among university students in Bangladesh is over 60%. We suggest adopting WHO Framework Convention on Tobacco Control (FCTC) policies, especially for university students.

Differences in tobacco smoking prevalence and frequency between adolescent Palestine refugee and non-refugee populations in Jordan, Lebanon, Syria, and the West Bank: cross-sectional analysis of the Global Youth Tobacco Survey.

BackgroundEvidence is conflicting as to the whether tobacco smoking prevalence is higher in refugee than non-refugee populations. The aim of this study was to compare the prevalence and frequency of tobacco smoking in Palestine refugee and non-refugee adolescent populations in the Middle East.MethodsWe conducted a cross-sectional analysis of the Global Youth Tobacco Survey (GYTS) conducted in Jordan, Lebanon, Syria, and the West Bank among adolescent Palestine refugees and non-refugees. Age- and sex-adjusted regression models assessed the association between refugee status and current (past-30 day) tobacco use prevalence and frequency.ResultsPrevalence estimates for current tobacco smoking were similar between Palestine refugee and non-refugee groups in Jordan (26.7 % vs. 24.0 %), Lebanon (39.4 % vs. 38.5 %), and the West Bank (39.5 % vs. 38.4 %). In Syria, Palestine refugees had nearly twice the odds of current tobacco smoking compared to non-refugees (23.2 % vs. 36.6 %, AOR 1.96, 95 % CI 1.46–2.62). Palestine refugees consumed more cigarettes per month than non-refugees in Lebanon (β 0.57, 95 % CI 0.17–0.97) and Palestine refugees consumed more waterpipe tobacco per month than non-refugees in Syria (β 0.40, 95 % CI 0.19–0.61) and the West Bank (β 0.42, 95 % CI 0.21–0.64).ConclusionsCurrent tobacco smoking prevalence is in excess of 20 % in both adolescent Palestine refugee and non-refugee populations in Middle Eastern countries, however Palestine refugees may smoke tobacco more frequently than non-refugees. Comparison of simple prevalence estimates may therefore mask important differences in tobacco use patterns within population groups.

Prevalence and Predictors of Current Tobacco Smoking in Bangladesh

Tobacco smoking is a leading modifiable global disease risk factor, with nearly 6 million premature deaths, 6.90% of years of life lost, and 5.5% disability-adjusted life-years (DALYs) in 2010 (1,2). Global age-standardized prevalence of daily tobacco smoking was 31.1% in 2012 for men (3). Nearly 80% of the more than one billion smokers worldwide live in low- and middle-income countries, where the burden of tobacco-related illness and death is heaviest (4). Given the importance of tobacco as a risk to health, monitoring the distribution and intensity of tobacco use is critical particularly for low- and middle- income countries. Data and Methodology: We have used secondary data of size 9629 (male=4468 and female=5161) aged 15 years and above collected by the Global Adult Tobacco Survey (GATS), 2010. Principle Component Analysis (PCA) has been used to get the wealth index. Binary logistic regression model has been used to assess the predictors of current tobacco smoking. Results: Prevalence of current tobacco smokers in Bangladesh was 23.19 (48.28% male and 1.47% female) and the prevalence of current daily tobacco smokers was 21.16. Rural respondents were significantly more likely to smoke tobacco currently. Comparative to females, males were more likely to smoke currently (adjusted OR=37.55, 95% CI=25.91, 54.41). Respondents of youngest age group (15-24 yrs) were less likely to smoke currently than all other age groups and respondents with no formal schooling were more likely to smoke than respondents with all other levels of education. Businessmen, farmers and workers/day labours were more likely to smoke, and employee, students and respondents with other jobs were less likely to smoke. It was also found that respondents with lowest wealth index were most likely to smoke and respondents with higher wealth index were least likely to smoke. Conclusion: The results reveal that in Bangladesh, tobacco smoking is strongly associated with social disadvantage, for example, low socio-economic status, less education, stressed or low-paid job, etc. Giving it as public health priority, WHO Framework Convention on Tobacco Control should be implemented. In addition, a nationwide campaign is needed to educate people in rural area about the health risks of smoking tobacco.

Smoking Trends among Brazilian population - National Household Survey, 2008 and the National Health Survey, 2013.

To compare current tobacco smoking prevalence in the Brazilian population and the federal states in adults (aged ≥ 18 years), using the National Household Survey 2008 and National Health Survey, 2013. Using data from two national surveys conducted in 2008 and 2013, the paper examines the current tobacco smoking prevalence in Brazil at the national level and at the federal state level. We calculated the percentage change for the period. Overall, results show -19% reduction in current tobacco smoking prevalence from 18.5% (2008) to 14.7% (2013). Results also show a significant percentage decline in smoking prevalence across geographic regions and demographic characteristics including gender, race, age and education levels. The decline occurred in all regions, urban and rural areas, and in most states. The reduction was -17.5% for men and -20.7% for women, having occurred in all age groups, with the greatest reduction in the group from 25 to 39 years of age; in all categories of race/color, a higher prevalence was found among the blacks and browns. It also declined in all the levels of schooling, with a higher reduction in lower education levels. In 2013, the prevalence for people with less education was 19.7% and 8.7% for those with college degrees. There was an average reduction of about 19% in tobacco consumption in Brazil and the Brazilian states in both sexes, all ages, and race color. Tobacco consumption in the country is one of the lowest in the world and has declined significantly, which can be attributed to the control policies, regulation, and prevention.

Prevalence of tobacco use among adults in South Africa: Results from the first South African National Health and Nutrition Examination Survey.

Data on tobacco use have informed the effectiveness of South Africa (SA)'s tobacco control strategies over the past 20 years. To estimate the prevalence of tobacco use in the adult SA population according to certain demographic variables, and identify the factors influencing cessation attempts among current smokers. A multistage disproportionate nationally representative stratified cluster sample of households was selected for the South African National Health and Nutrition Examination Survey, conducted in 2012. A sample of 10 000 households from 500 census enumerator areas was visited. A detailed questionnaire was administered to all consenting adults in each consenting household. Of adult South Africans, 17.6% (95% confidence interval (CI) 6.3 - 18.9) currently smoke tobacco. Males (29.2%) had a prevalence four times that for females (7.3%) (odds ratio 5.20, 95% CI 4.39 - 6.16; p<0.001). The provinces with the highest current tobacco smoking prevalence were the Western Cape (32.9%), Northern Cape (31.2%) and Free State (27.4%). Among current tobacco smokers, 29.3% had been advised to quit smoking by a healthcare provider during the preceding year, 81.4% had noticed health warnings on tobacco packages, and 49.9% reported that the warning labels had led them to consider quitting. A large proportion of adult South Africans continue to use tobacco. While considerable gains have been made in reducing tobacco use over the past 20 years, tobacco use and its determinants need to be monitored to ensure that tobacco control strategies remain effective.

Predicting tobacco smoking among male adolescents in Hamadan City, west of Iran in 2014: an application of the prototype willingness model.

As adolescent tobacco smoking has become a widespread problem in developing countries, it is time to understand the cognitive determinants of adolescents' decisions to engage in tobacco smoking. This study aimed to investigate the predicting factors associated with tobacco smoking among male adolescents based on Prototype Willingness Model (PWM) as a theoretical framework. This descriptive-analytical study was carried out on 810 male adolescents of Hamadan City western Iran, recruited with a multistage sampling method. The data-gathering tool consisted of a questionnaire based on the PWM constructs. Data analysis was performed using SPSS-19 software, by bivariate correlations, liner and logistic regression tests. The prevalence of current tobacco smoking was 17.2%. Behavioral willingness and subjective norms were the most important predictors of behavioral intentions, whereas subjective norms, attitude and prototype were the most important predictors for behavioral willingness. The result obtained from logistic regression analysis revealed that both pathways of PWM constructs [behavioral intention (OR=1.207; 95% CI: 1.13, 1.28) and behavioral willingness (OR=1.334; 95% CI: 1.25, 1.41) were significant predicting factors for tobacco smoking among male adolescents. The framework of the PWM is applicable and useful in understanding tobacco smoking among male adolescents. In addition, the results revealed the importance of social reaction path when examining adolescents' smoking status.

The Correlation between Gender Inequalities and Their Health Related Factors in World Countries: A Global Cross-Sectional Study

The study aimed to investigate gender inequalities and their health associated factors in world countries. A cross-sectional survey was undertaken using data of United Nations Development Programme (UNDP) and World Health Organization (WHO). The main variable in this study was gender inequality index (GII). All countries were stratified by WHO regions. Pearson correlation coefficient was used to assess the linear correlation between GII and investigated factors by WHO regions. The mean of GII was greater in Africa and lower in Europe region. There was negative significant association between GII and life expectancy at birth and mean years of schooling, prevalence of current tobacco smoking, high blood pressure and overweight and obesity, alcohol consumption rate, and cancer death rate. But there was positive significant association between GII and noncommunicable diseases death rates. In conclusion, gender inequalities, though decreasing over the past decades in world, remain notably greater in Africa and Eastern Mediterranean regions than in Europe. Gender inequality is also an important issue which is related to health factors. Hence, countries will need to focus on public health intervention and equal distribution of economic resources to reduce gender inequality in society.

Tobacco use in pregnant women: analysis of data from Demographic and Health Surveys from 54 low-income and middle-income countries.

Worldwide, use of tobacco is viewed as an important threat to the health of pregnant women and their children. However, the extent of tobacco use in pregnant women in low-income and middle-income countries (LMICs) remains unclear. We assessed the magnitude of tobacco use in pregnant women in LMICs. We used data from Demographic and Health Surveys (DHS) done in 54 LMICs between Jan 1, 2001, and Dec 1, 2012, comprising 58 922 pregnant women (aged 15-49 years), which were grouped by WHO region. Prevalence of current tobacco use (smoked and smokeless) was estimated for every country. Pooled estimates by regions and overall were obtained from random-effects meta-analysis. Pooled prevalence of any tobacco use in pregnant women in LMICs was 2·6% (95% CI 1·8-3·6); the lowest prevalence was in the African region (2·0%, 1·2-2·9) and the highest was in the Southeast Asian region (5·1%, 1·3-10·9). The pooled prevalence of current tobacco smoking in pregnant women ranged from 0·6% (0·3-0·8) in the African region to 3·5% (1·5-12·1) in the Western Pacific region. The pooled prevalence of current smokeless tobacco use in pregnant women was lowest in the European region (0·1%, 0·0-0·3) and highest in the Southeast Asian region (2·6%, 0·0-7·6). Overall, tobacco use in pregnant women in LMICs was low; however high prevalence estimates were noted in some LMICs. Prevention and management of tobacco use and exposure to second-hand smoke in pregnancy is crucial to protect maternal and child health in LMICs. None.

Smoking and Associated Factors Among the Population Aged 40-64 in Shahroud, Iran

Smoking is known as a major risk factor for different types of cancer, as well as cardiovascular disease. Its prevalence is increasing in developing countries. The aims of this study were to determine the prevalence of smoking and its associated factors among the population aged 40-64 years in the city of Shahroud which is a representative urban population in Iran. A cross-sectional population-based study with stratified random cluster sampling was conducted in 2009 as the first phase of Shahroud Eye Cohort Study. Of 6,311 people, 5,190 participated (82.2%). Information about smoking habit was obtained by face-to- face interview. The overall prevalence of current tobacco smoking was 11.3% (95%CI: 10.5-12.3). It was significantly higher among males than females (25.7% and 0.71%, P<0.001). The prevalence of current cigarette smoking was 10.8% and 1.75% were past smokers. The smoking rate of water-pipe was 0.67%. Unemployed people smoked more than employed (OR=2.66, 95%CI: 1.38-5.14). The prevalence of smoking is low in Shahroud compared with other parts of Iran and other countries. Age, sex, job and marital status were associated with smoking. The low smoking rate among women may be attributed to cultural and social reasons.

Tobacco smoking among people living with a psychotic illness: The second Australian survey of psychosis

The aims of this study were to (a) describe patterns of tobacco smoking among Australians living with a psychotic illness and (b) explore the association between smoking and measures of psychopathology, psychiatric history, psychosocial functioning, physical health, substance use and demographic characteristics. Data were from 1812 participants in the 2010 Australian Survey of High Impact Psychosis. Participants were aged 18-64 years and resided in seven mental health catchment sites across five states of Australia. Bivariate statistics were used to compare smokers with non-smokers on the measures of interest, and to compare ICD-10 diagnostic categories on measures of smoking prevalence, nicotine addiction and quitting history. Multivariate logistic regression was used to test whether (a) demographics and psychiatric history were associated with having ever smoked and (b) whether symptoms and psychosocial functioning were independently associated with current smoking, after controlling for demographics, psychiatric history and substance use. The prevalence of current tobacco smoking was 66.6% (72% of men and 59% of women); lifetime prevalence was 81%. In univariate analyses, individuals with a diagnosis of schizophrenia or schizoaffective disorder were most likely to be smoking tobacco (70%) and were more nicotine dependent. Smokers reported worse perceived physical health, lower body mass index and waist circumference, and more lifetime medical conditions. A younger age of illness onset, male gender and low education were associated with having ever smoked. Associations with current smoking included low education, male gender, no formal employment, worse negative symptoms, higher daily caffeine consumption, and alcohol dependence and substance abuse/dependence. The prevalence of tobacco smoking is high amongst people with a psychotic disorder, and is associated with adverse mental health symptoms as well as high rates of other substance use, poorer subjective physical health, and a higher risk of the many known health consequences of smoking.

Regionale und soziale Unterschiede im Tabakkonsumverhalten im Mikrozensus 2009: Ergebnisse für das Land Nordrhein-Westfalen und dessen Kreise

Tobacco smoking is the single greatest cause of avoidable morbidity and mortality. The official Microcensus is one of the most important sources of systematic reporting about smoking in Germany. The selection rate of the random sample survey was 1% of the population in the 2009 Microcensus in North Rhine-Westphalia. Most of the information was given under statutory obligations. Providing health information in the health supplementary programme was optional with response of about four-fifths of the interviewees. According to the 2009 Microcensus regional file, 37% of the men and 28% of the women of employable age (15-64 years) are smokers in North Rhine-Westphalia (N=9 219 thousand). Tobacco smoking prevalence is associated with influencing social factors. The probability of current smoking rises with the decrease of the socioeconomic status and the level of education. Job-seekers have a significantly elevated odds ratio for smoking, the chance of quitting smoking is minimised. The analyses show that the percentages of smokers and ex-smokers varied widely between the communities in North Rhine-Westphalia. The prevalence of current tobacco smoking increases highly in the communities with rates of inhabitants who receive government financial aid or unemployment benefits to secure their basic livelihood. The Microcensus reveals distinct disparities in adult smoking prevalence between the regions and additionally strong social disparities in adult smoking prevalence. The nicotine addiction accelerates health inequalities. The Microcensus may have potential for monitoring tobacco use in Germany and in the regions and communities and for evaluating the effectiveness of tobacco control programmes over time. The Microcensus analyses can be used for the development of primary and secondary tobacco prevention strategies.

Prevalence of COPD and tobacco smoking in Malopolska region – results from the BOLD Study in Poland

There is a paucity of population-based data on chronic obstructive pulmonary disease (COPD) prevalence in Poland. To address this problem we participated in the Burden of Obstructive Lung Disease (BOLD) Initiative which was developed to provide standardized methods for estimating the prevalence of COPD and its risk factors. The study aimed to assess the prevalence of COPD and some of its risk factors in adults aged 40 years and older in the Malopolska region in southern Poland. Region--representative sample was drawn, basing on the current census data. Detailed BOLD questionnaires as well as pre- and post-bronchodilator spirometry were applied to eligible individuals. Six hundred and three subjects provided questionnaire and spirometry data; of those 526 provided spirometry data of appropriate quality and were included in the final analysis. Estimated population prevalence of COPD was 22.1%, whereas 10.9% had COPD in GOLD Stage > or = 2. COPD was far more common in men and its prevalence increased with age and exposure to tobacco smoke, and was inversely related to education level. The prevalence of current tobacco smoking was 28% (34% and 22% in men and women, respectively). Seventy-nine percent of men and 42% of women were ever-smokers. Twenty-nine percent of never smoking individuals were passively exposed to tobacco smoke in their households. Our results confirm the high prevalence of COPD in the studied region of Poland and emphasize the need to increase efforts to improve COPD awareness and limit tobacco smoking habit.
