Prevalence Of Tobacco Smoking Research Articles

Evaluation of E-Cigarette Use in Opioid-Dependent Patients in Maintenance Treatment.

As tobacco smoking decreases, the use of e-cigarettes is on the rise. There is a debate whether switching from smoking to the use of e-cigarettes might represent a harm reduction strategy for those who smoke tobacco heavily, a habit often observed in individuals with opioid dependence. The present study investigated the prevalence and patterns of tobacco smoking and e-cigarette use in patients in opioid maintenance treatment (OMT) and whether e-cigarette use contributed to the cessation of smoking tobacco. In 2014 (n=84) and in 2021 (n=128), patients from two OMT clinics of a psychiatric university hospital were interviewed RESULTS: In both surveys, patients presented with a comparable average age (45.6 vs. 46.9 years of age), gender distribution (mainly male 71.4 vs. 75.8%), and length of OMT history (median: 66 vs. 55 months). The lifetime prevalence of e-cigarette use (45.2% in 2014 and 38.3% in 2021) was much higher than the current prevalence (4.9% and 7.8%, respectively). Few patients reported either a complete switch from smoking to the use of e-cigarettes (2014, n=1 vs. 2021, n=2) or the achievement of abstinence from smoking after a temporary use of e-cigarettes (2014, n=2 vs. 2021, n=1). No increase in the use of e-cigarettes was observed in these groups of patients undergoing OMT. Presumably, harm reduction strategies relating to the use of e-cigarettes in this group need to be supported by motivational interventions. Given the high morbidity and mortality due to smoking, OMT clinics should offer professional help in reducing smoking.

Bringing the group back in: Social class and resistance in adolescent smoking.

Absolute prevalence of tobacco smoking has fallen in recent decades but inequalities by socioeconomic position (SEP) persist. Adolescence is a critical period for smoking initiation and habits formed during this period likely continue into adulthood. Explanations for inequalities in adolescent smoking have tended to focus on individualistic theories based on differentials in knowledge and psychology. These have been criticised for their blindness to processes of social stratification and social context that influence smoking behaviours. Based on previous social theories, we put forward, and test empirically, two potential structural explanations for inequalities in smoking, using nationally representative longitudinal cohort data on 6039 Irish young people aged 9-18years. Descriptive analyses confirmed the adverse SEP gradient in smoking prevalence as well as SEP gradients in variables representing individual-level characteristics and structural-level explanations. Despite lower self-esteem being associated with a higher likelihood of smoking, there was no significant indirect pathway between SEP and smoking via self-esteem. Path analyses found that differentials in exposure to parental smoking and levels of oppositional values mediate the relationship between SEP and smoking. Our results favour structural and group-based explanations for inequalities, that is, the 'smoking exposure' and 'social resistance' models, over explanations based on individual psychology.

Disparities in tobacco smoking and risk of cardiovascular disease in people with low socioeconomic status or serious psychological distress: A simulation analysis

High tobacco smoking prevalence in people with low SES or serious psychological distress (SPD) in the U.S. may increase cardiovascular disease (CVD) risk among these marginalized subpopulations. We estimate how smoking disparities contribute to CVD disparities. Using the Simulation of Tobacco and Nicotine Outcomes and Policy model, a validated microsimulation model of tobacco use and clinical outcomes, we used 2004-2019 data from the National Health Interview Survey to first compare 20-year cumulative CVD incidence for 40-year-olds by sex, smoking status, and marginalized subpopulation membership. Second, we simulated the marginalized subpopulations with representative age, sex, and smoking status distributions to estimate 20-year cumulative CVD incidence under status quo and counterfactual scenarios. In the counterfactual scenario, smoking prevalence and trends in the low SES and SPD subpopulations match those in the higher SES and non-SPD subpopulations, respectively. The model-projected impact of smoking on 20-year cumulative CVD incidence is considerably larger than the impact of low SES or SPD; for example, among 40-year-old males, cumulative CVD incidence is 28.3% for low SES people who currently smoke, 13.0% for low SES people who never smoke, and 26.2% for higher SES people who currently smoke. In the second analysis, in the status quo scenario, model-projected 20-year cumulative CVD incidence is 19.3% for low SES and 22.1% for SPD; in the counterfactual scenario, it is 18.1% for low SES and 19.6% for SPD. Interventions focused on reducing smoking disparities could substantially reduce CVD in marginalized subpopulations.

Clinical assessment of the respiratory system in pregnant women on the background of nicotine addiction

Smoking is not only a modifiable risk factor for adverse pregnancy outcomes, it is primarily a risk factor for the development of pathology of the respiratory system, eventually turning into chronic obstructive pulmonary disease (COPD). The high prevalence of tobacco smoking among pregnant women, confirmed by numerous studies, demonstrates the underestimation of the high risks of COPD development. The present study substantiates the relevance of timely detection of pathological changes in the bronchi in smokers in primary care and the formation of motivations to quit smoking. It is the desired pregnancy that can cause complete cessation of smoking, thereby reducing the risks of developing not only the pathology of the smoker's lungs, but also the pathology of the fetus.

Predictors and health outcomes of cigarette and shisha smoking among men in Gaza: a cross-sectional study

Tobacco smoking, a significant public health concern globally, is associated with a rise in noncommunicable diseases (NCDs) and preventable deaths, with pronounced impacts in conflict zones like Gaza. A cross-sectional study, conducted in 2020, in Gaza focused on individuals over 40 years of age, aiming to identify predictors of tobacco use and its links to diseases like coronary artery disease (CAD), chronic lung disease (CLD), and stroke using regression analysis. The research, based on the Gaza NCD study data with 4576 participants and a 96.6% response rate, found an overall tobacco smoking prevalence of 19.4%, with higher rates among men. After adjusting for various factors, the study identified significant associations between cigarette smoking in men and adverse health outcomes, such as CAD and CLD, with adjusted odds ratios (OR) of 1.67, 95% CI (1.22–2.29) and 1.68, 95% CI (1.21–2.33) respectively. However, after adjusting for independent variables, shisha smoking in men showed no association with these health outcomes. The findings of this study could assist other researchers in designing interventions aimed at reducing smoking prevalence by utilizing the associated factors identified in our analysis, such as age, education level, physical activity, and body mass index among men in Gaza.

COVID-19 Impact on Substance Use (Tobacco, Alcohol, Cannabis) and Stress in Medical Students

The COVID-19 pandemic has led to unprecedented challenges globally, impacting various aspects of daily life, including education. This study examines the effects of the pandemic on stress levels and substance use among Italian medical students. Two independent surveys were conducted: 388 medical students were interviewed before the epidemic, and 222 medical students a year after the COVID-19 epidemic began. Results revealed significant changes in stress levels, with a reduction in mild stress and an increase in severe stress during the post-pandemic period, rising from 23% (95% CI: 19%-28%) to 46% (95% CI: 39%-52%). While tobacco smoking prevalence remained stable (25% vs 27%), the proportion of students exhibiting high levels of nicotine dependence increased (3.64%) compared to the period before the pandemic (1.80%). Alcohol consumption rates remained consistent (66%), with no significant differences in the distribution of risky alcohol consumption between the two periods (<em>p</em> = 0.535). Surprisingly, there was a significant decrease in cannabis use post-pandemic (16% vs 6%), though problematic use among users persisted (49% vs 46%). Multivariable analysis confirmed associations between stress and tobacco smoking (AdjOR = 1.98, 95% CI: 1.11-3.53; <em>p</em> = 0.020), as well as alcohol consumption (AdjOR = 1.71, 95% CI: 1.01-2.89; <em>p</em> = 0.047). Furthermore, male students were more likely to engage in alcohol (AdjOR = 2.16, 95% CI: 1.47-3.19; <em>p</em> < 0.001) and cannabis use (AdjOR = 1.79, 95% CI: 1.07-3.00; <em>p</em> = 0.027). The study highlighted the complex interplay between stress and substance use among medical students, underscoring the importance of targeted interventions to address stress-related substance use and support the well-being of medical students, particularly in the context of the COVID-19 pandemic. Further research should explore longitudinal trends and the effectiveness of interventions in mitigating stress-related substance use among this vulnerable population.

Spotlight on nurses' smoking prevalence and addiction in Istanbul, Türkiye, the leading country in the implementation of WHO MPOWER policies

ObjectiveTürkiye is the leading country that has been applying the MPOWER criteria of the World Health Organization for years. However, the prevalence of smoking among nurses appears to be high, according to the literature. Therefore, we aimed to determine the prevalence, addiction levels, and dynamics of tobacco smoking among nurses in Türkiye.MethodIn this descriptive cross-sectional study, a questionnaire (prepared in cooperation with the “World Health Organization”) and the Fagerström Test for Nicotine Dependence were administered to 529 nurses working at a tertiary-care university hospital in 2020. Logistic regression was performed to determine factors predicting smoking.ResultsThe prevalence of smoking among nurses was 32.7% (n = 173). The mean Fagerström test score indicated a "low dependence" level (score: 3 ± 2.6). Both results were higher for males. A relationship was found between trying smoking cigarette and hookah. Of the “current smokers” group, 102 (60.4%) stated that they wanted to quit smoking. Only 21 (27.6%) of the nurses who have tried to quit smoking thus far have received professional help.ConclusionThe prevalence of smoking among nurses working at a tertiary-care university hospital was relatively low compared to that among nurses in Türkiye. While females are normally expected to smoke less, the high prevalence of smoking among nurses (most of them female) raises the question of the professional basis of this situation. However, the low rate of receiving professional help reveals the lack of promotion and accessibility of smoking cessation outpatient clinics in the faculty environment. Finally, the perception that hookah is an alternative tobacco product leads to cigarette smoking. The good news was that nurses had a low dependency rate.

Comparative analysis of the prevalence of smoking and consumption of nicotine-containing products and their risk factors among students of medical and technical universities of Saint Petersburg based on data from the PROTECT study

BACKGROUND: Taking into account the importance of quitting smoking of any nicotine-containing products by young people in various social groups, a comparative analysis of the prevalence of smoking tobacco and nicotine-containing products among students of medical and technical universities in St. Petersburg was carried out. AIM: To compare the prevalence and structure of consumption of tobacco and nicotine-containing products, as well as the smoking behavior of students at medical and technical universities. MATERIALS AND METHODS: A cross-sectional cross-sectional study of a random sample of student groups included 1,105 respondents. RESULTS: The prevalence of tobacco smoking among students at a technical university was 2 times higher than at a medical university (p 0.01). Cigarette smoking was also more often noted at the onset of smoking among engineering students and in their families (p 0.05). 17.2% of North-Western State Medical University named after I.I. Mechnikov students and 14.2% of Saint Petersburg Electrotechnical University “LETI” named after V.I. Ulyanov (Lenin) students consume nicotine-containing products. Men from the medical university smoke cigarettes significantly more often than women, or use nicotine-containing products, as well as a combination of both. No similar gender differences were found at the technical university. Female doctors used ES more often than women from a technical university at the beginning of smoking (p 0.05). Men at a medical university started using nicotine-containing products more often than women, considering them the least dangerous to health (p 0.05). The example of friends was the most common reason for starting smoking among respondents from both universities (43.9 and 30.8%, respectively). Common risk factors for smoking any product among students of North-Western State Medical University and LETI were boyfriend/girlfriend smoking, smoking among one’s immediate environment. Studying in senior years was a protective factor for girls at a medical university in comparison with students at a technical university (odds ratio 0.48). CONCLUSIONS: The data obtained on the lower prevalence of tobacco smoking among medical university students compared to technical students may indirectly indicate the latter’s insufficient knowledge about the harmful effects of tobacco smoking on the body. The high prevalence of nicotine-containing products consumption in universities of various fields of study and the lack of significant differences in the share of their consumers can also be interpreted as an underestimation of the health risks of new smoking products. This requires adjustments to educational programs in order to increase students’ awareness of the potential health hazards not only of smoking cigarettes, but also of using any nicotine-containing products.

Prevalence of tobacco smoking and related factors in people aged 15 years and above in Beijing, 2014-2021

Objective: To evaluate the effect of the implementation of Beijing Smoking Control Regulation in 2015 on the smoking prevalence in people aged ≥15 years in Beijing during 2014-2021, and explore factors associated with tobacco use behavior in local population. Methods Using a pooled cross-sectional design, data from Beijing Adult Tobacco Survey in 2014, 2016, 2019 and 2021 (4 surveys) were combined into one dataset. The 4 surveys used same multistage cluster sampling procedure. After complex survey weighting, multiple logistic regression models were constructed to analyze factors influencing smoking status. Results: A total of 8 484, 9 372, 8 534 and 10 551 respondents were included in the surveys in 2014, 2016, 2019 and 2021, respectively. The smoking prevalence rate was 23.4%, 22.3%, 20.3% and 19.9%, respectively, in Beijing residents aged ≥15 years, exhibiting a linear declining trend (P=0.010). Factors associated with current smoking in men were age 25-44 years (OR=2.22, 95%CI: 1.68-2.95) and 45-64 years, (OR=2.64, 95%CI: 2.06-3.39), educational level of high school (OR=0.69, 95%CI: 0.49-0.95) and undergraduate and above (OR=0.46, 95%CI: 0.33-0.63), and awareness of smoking causing stroke (OR=0.71, 95%CI: 0.61-0.81), and awareness of smoking causing lung cancer (OR=0.53, 95%CI: 0.42-0.66), the differences were significant (all P<0.05). After controlling interfering factors, the current smoking prevalence in men in 2019 (OR=0.73, 95%CI: 0.63-0.87, P<0.001) and 2021 (OR=0.72, 95%CI: 0.61-0.88, P<0.001) were significantly lower than that in 2014. Factors associated with current smoking in women were living alone (OR=1.80, 95%CI: 1.33-2.44), educational level of undergraduate and above (OR=0.43, 95%CI: 0.27-0.69), other occupations except doctor and teacher (OR=8.54, 95%CI: 2.80-26.02) or being retired/unemployed (OR=9.39, 95%CI: 3.19-27.65), and awareness of smoking causing cardiovascular events (OR=0.58, 95%CI: 0.39-0.84), and awareness of smoking causing lung cancer (OR=0.54, 95%CI: 0.35-0.83), the differences were significant (all P<0.05). No significant change in smoking status in women was found in 4 surveys. Conclusions: The smoking prevalence rate in men in Beijing has declined since the implementation of Beijing Smoking Control Regulation 5 years, indicating the effectiveness of legislative approach in tobacco control. Socio-demographic factors and the awareness level of tobacco harm could influence smoking status. Future tobacco control programs should target the people with lower education level, young men, women living alone, and those with occupations other than teachers/doctors or the unemployed/retired and include more comprehensive health education.

Prevalence of Tobacco Smoking in A Sample of General Secondary School Students in Cairo and Its Correlation to Other Psychiatric Disorders

Abstract Background Tobacco smoking is considered currently as a global public health concern among youth especially school student. There is a scarcity of data about the impact of this global phenomenon in Middle Eastern countries. This study assesses the prevalence of tobacco smoking, including conventional cigarettes, E-cigarettes and waterpipe and its sociodemographic and psychiatric correlates among a sample of general secondary school students in Cairo, Egypt. Results A convenient sample of 391 Egyptian general secondary students from different areas of Greater Cairo were assessed using the Socioeconomic scale, Fagerstrom Test For Nicotine Dependence, The Lebanon Water pipe Dependence Scale, questionnaire for electronic cigarette using, Barratt impulsivity scale 11, The MINI International Neuropsychiatric Interview for Children and Adolescents. 12.8% (n = 50) were smokers. There is significant relation between family history of smoking and substance use and smoking and significant relation between smoking, impulsivity and mood symptoms. Conclusions Prevalence of tobacco smoking in Egyptian adolescents was 12.8% with significant relation between smoking and impulsivity and mood symptoms.

Exposure to Waterpipe Smoke Disrupts Erythrocyte Homeostasis of BALB/c Mice

The prevalence of waterpipe tobacco smoking (WPS) is increasing worldwide and is relatively high among youth and young adults. It has been shown, both experimentally and clinically, that WPS exposure adversely affects the cardiovascular and hematological systems through the generation of oxidative stress and inflammation. Our study aimed to evaluate the impact of WPS exposure on erythrocytes, a major component of the hematological system, of BALB/c mice. Here, we assessed the effect of nose-only WPS exposure for four consecutive weeks on erythrocyte inflammation, oxidative stress, and eryptosis. The duration of the session was 30 min/day, 5 days/week. Control mice were exposed to air. Our results showed that the levels of C-reactive protein, lipid peroxidation (LPO), superoxide dismutase, and total nitric oxide (NO) were significantly increased in the plasma of WPS-exposed mice. The number of erythrocytes and the hematocrit were significantly decreased in WPS-exposed mice compared with the control group. Moreover, there was an increase in the erythrocyte fragility in mice exposed to WPS compared with those exposed to air. The levels of lactate dehydrogenase, LPO, reduced glutathione, catalase, and NO were significantly increased in the red blood cells (RBCs) of WPS-exposed mice. In addition, erythrocytes of the WPS-exposed group showed a significant increase in ATPase activity, Ca2+, annexin V binding, and calpain activity. Taken together, our findings suggest that WPS exposure elevated inflammation and oxidative stress in the plasma and induced hemolysis in vivo. It also caused alterations of RBCs oxidative stress and eryptosis in vitro. Our data confirm the detrimental impact of WPS on erythrocyte physiology.

Clinic-Functional Assessment of Hemoglobin Desaturation by Oxygen in 6-Minute Walk Test Among Patients with Bronchial Asthma

The main purpose of the study is to assess the prevalence and clinical significance of hemoglobin desaturation by oxygen during the 6-minute walk exercise test in patients with bronchial asthma. Material and methods: 75 patients with exacerbation of mixed (48 %) and allergic (52 %) bronchial asthma were examined. Research explored following methods: collecting complaints and anamnesis, physical examination, spirometry, CO-metry of exhaled air to determine carboxyhemoglobin, transcutaneous 2-wave pulse oximetry (at rest and during 6-minute walk exercise test) with spectral analysis and correction for COHb. 6-minute walk exercise test was performed after relief of asthma exacerbation (before discharge from the hospital), assessing the desaturation-distance ratio (the ratio of the area of oxygen desaturation of hemoglobin to the 6-minute walk exercise test distance), O2-GAP index, the dynamics of fatigue and dyspnea before and after 6-minute walk exercise test. In smoking patients (n = 36, 48 %), the smoker index was calculated. Based on oximetry results during the 6-minute walk exercise test, patients were divided into “desaturators” (n = 28, 37 %) and “non-desaturators” (n = 47, 63 %). Results. The findings of the research illustrated that hemoglobin desaturation by oxygen, detected by reducing SpO2 to &lt; 90 % during 6-minute walk exercise test, was associated with the severity of this disease exacerbation, more pronounced impairment of pulmonary ventilation and blood oxygenation, and the demand for longer hospitalization. The prevalence of tobacco smoking and the magnitude of the smoker index in both groups were identical but in “desaturators” we found a higher prevalence of the combination of asthma and COPD compared to “non-desaturators.” The “desaturators” had significantly higher level of desaturation-distance ratio and increased demand for additional oxygen flow to maintain SpO2 at ≥ 88 % during a 6-minute walk test, which indicates a higher “oxygen price” of physical activity in this group of patients. Conclusion. Thus, the high prevalence of the phenomenon of hemoglobin oxygen desaturation during 6-minute walk exercise test in patients with asthma and associated clinic-functional disorders supports the feasibility and clinical significance of conducting a stress test with a 6-minute walk not only in COPD patients, but also in bronchial asthma patients.

Patterns and determinants of tobacco purchase behaviors among male cigarette smokers in Vietnam: A latent class analysis.

Understanding smokers' purchasing patterns can aid in customizing tobacco control initiatives aimed at reducing the tobacco smoking prevalence. Therefore, this study identified cigarette purchase behavior among Vietnamese male smokers and associated demographic and consumption factors. We analyzed a secondary dataset of male current tobacco smokers (n=3983) who participated in the Vietnam Global Adult Tobacco Survey in 2015. We applied the latent class analysis (LCA) to identify the classes of purchase behavior among cigarette smokers (n=1241). Multinomial logistic regression was performed to identify demographics (education level, ethnicity, partnership status, and household socioeconomic status) and cigarette consumption variables (smoking years and heavy smoking status) related to purchase behavior classes. The results are reported as an adjusted relative risk ratio (ARRR). The LCA identified four cigarette purchase behaviors classes: Class 1 (price-insensitive and purchased international brand: 44.4%), Class 2 (price-sensitive and purchased domestic brand: 27.6%), Class 3 (price-sensitive and purchased cigarettes in a street vendor: 18.6%), and Class 4: price-sensitive and purchased loose/carton cigarette: 9.4%). The poorer economic groups were more likely to belong to the three price-sensitive classes. Heavy smokers and those who had smoked for a longer period were more likely to belong to Class 3 (ARRR=2.33; 95% CI: 1.51-3.58 and ARRR=1.02; 95% CI: 1.001-1.05, respectively) and Class 4 (ARRR=2.94; 95% CI: 1.71-5.06 and ARRR=1.05; 95% CI: 1.02-1.08, respectively). Varied purchasing behaviors among male cigarette smokers, influenced by divergent price sensitivities and economic backgrounds, underscore the need for comprehensive tobacco control. Future efforts should include targeted policy interventions, behavior modification, and reshaping social norms.

Geographic and sociodemographic variations in disease burden, epidemiological trends, and risk factors of early-onset lung cancer: A global analysis.

11169 Background: Exploring the emerging trend of early-onset lung cancer (EOLC) burden is pivotal for guiding the implementation of preventive strategies among young adults. We aimed to provide a comprehensive examination of the geographic and sociodemographic variations in the disease burden, along with epidemiological trends and risk factors associated with EOLC over the past three decades. Methods: EOLC refers to lung cancer diagnosed in individuals aged 20-49 years. Utilizing the GBD 2019 data, we estimated the age-standardised incidence, mortality, and disability-adjusted life years (DALYs) rates for EOLC by sex, socio-demographic index (SDI) quintiles, and geographical location for the period from 1990 to 2019. We investigated the relationships between concomitant risk factors and EOLC incidence at national level, and calculated the DALYs attributable to risk factors. The relative contribution of population growth, population ageing, and epidemiological changes to the variations in burden of EOLC over study period was measured using the decomposition analysis. Incidence was forecast to 2040 using the Bayesian age-period-cohort model. Results: A total of 135,704 EOLC cases, equating to a age-standardised incidence rate of 4.0 (95% UI 3.6 to 4.3) per 100,000, were estimated in 2019 worldwide and was the second leading cause of cancer death among young adults, with higher disease burden occurred in males and those from middle and high-middle SDI regions. An overall decreasing trend in burden of EOLC was observed globally; such trends were more pronounced among males and followed a gradient across SDI levels, with the greater decrease observed in high and high-middle SDI regions. Sex, tobacco smoking prevalence, per capita cigarette-equivalent estimates, average age of smoking initiation, ambient ozone pollution, and GDP per capita were independently and significantly associated with EOLC incidence at the population level. Smoking remained the top contributor to burden of EOLC, with the exception of Andean Latin America, North Africa, and the low SDI regions, where ambient particulate matter pollution and household air pollution from solid fuels ranked as the foremost attributable risk factors. Population growth was the primary driver behind the global increase in EOLC cases in low and low-middle SDI regions, while epidemiological changes accounted for the most substantial reduction in EOLC cases across most regions. The global incidental cases of EOLC was projected to increase by 31.1% in 2040, with a more pronounced increase in females and those from high-middle and middle SDI locations. Conclusions: Our findings underscore significant geographic and sociodemographic disparities in the epidemiological burden of EOLC, emphasizing the necessity for policymakers to devise and apply region-specific, evidence-driven preventive strategies.

Systematic review of tobacco smoking prevalence among young people in treatment for first-episode psychosis.

To determine whether smoking prevalence in first-episode psychosis (FEP) is different than in people with established psychosis in long-term treatment. A systematic review of cross-sectional, case-control and cohort studies identified from searches of PubMed, Embase, CINAHL and PsycINFO up to 12 August 2023. 20 studies out of 2773 screened titles were included. There was no clear pattern of smoking by diagnosis as smoking rates in people with FEP ranged from 43% to 78%, while in those with established psychosis, it ranged from 19% to 76%. The wide range of smoking levels in both populations precluded conclusions as to whether smoking rates are different between people with FEP and established psychosis suggesting that factors other than the time course of the illness influence smoking levels.

Health policy developments in the Western Balkan Countries 2000-19: towards European Health and Health Care Policies.

Albania, Bosnia and Herzegovina, Kosovo, Montenegro, North Macedonia and Serbia have committed to becoming European Union (EU) member states. This, among others, implies that candidate/potential candidate states adopt legally authorized EU policies, including health. The study aims to identify the main country-specific health policy areas critical to the EU accession health policy dimension and present the change in associated selected health indicators from 2000 to 2019. The study draws on published reports and analyses of official statistics over time and cross-country. Health care policy adherence to the European Commission's recommended country-specific health actions was classified into five health policy areas: financing, payment, organization, regulation and persuasion. Key health policy areas for Western Balkan countries (WBCs) were identified. Health progress or lack thereof in catching up to the EU15 population health, health expenditure and the number of health professionals are measured. The European Commission prioritized financing and regulation for all WBCs in the five policy areas. Nine of the 18 analyzed selected health indicators showed divergence, and the other nine converged towards the EU15 averages. WBCs continue to face diverse public health challenges in improving life expectancy at birth, death rates caused by circulatory system diseases, malignant neoplasms, traffic accidents, psychoactive substance use, tuberculosis incidence, tobacco smoking prevalence and public-sector health expenditure. By 2019, there is limited evidence of WBCs catching up to the average EU15 health levels and health care policies. Closer attention towards EU health and health care policies would be favourable.

Prevalence of tobacco smoking and the knowledge and attitudes on prevention of tobacco smoking among schooling adolescents in the age group of 13 &amp;ndash; 15 years in the Kandy district in 2018

Introduction: The early age of tobacco smoking initiation among adolescents reported in Sri Lanka highlights the need to initiate tobacco prevention at a very young age.Objectives: To determine the prevalence of tobacco smoking, the knowledge, and attitudes on prevention of tobacco smoking among schooling adolescents in government schools in the age group of 13-15 years in the Kandy district in 2018.Methodology: A cross-sectional study was conducted among 1395 students in selected government schools in the Kandy district. The subjects were selected using a stratified multi-stage cluster sampling method. A pretested self-administered questionnaire was used.Results: The response rate was 97.1%. The Prevalence of ever tobacco smoking in the age group of 13 to 15 years, was 6.02% (95% CI, 4.83% - 7.40%). The prevalence of current smokers was 4.16% (3.23% - 5.24%). Satisfactory knowledge of the harmful effects of tobacco smoking was shown by 49.6% (n=692) of ever smokers. The majority (71.5%, n=997) showed favourable attitudes towards the prevention of smoking. There was a higher likelihood of smoking among students who had unsatisfactory knowledge (OR = 8.203; 95% CI = 4.142 – 16.247) and attitudes (OR=1.172; 95% CI=1.112 – 1.225) compared to students who had satisfactory knowledge and attitudes.Conclusions: The prevalence of tobacco smoking in the selected age group was high in the Kandy district compared to the national rates. School interventions should target more students who already smoke to improve their knowledge and attitudes.
