The effect of tobacco control policy on smoking cessation in relation to gender, age and education in Lithuania, 1994-2010

Efficacy of a Smoking Cessation Program for Underserved Ethnic Minority Communities: Results of a Smoking Cessation Trial

Objectives: Using a participatory research approach, this study reports the efficacy of the Communities Engaged and Advocating for a Smoke-free Environment (CEASE)-4 intervention offered by the local peers. Methods: CEASE-4 is a theory-based tobacco-cessation intervention, tailored to the needs of underserved populations. 842 tobacco users self-selected into: a) self-help (n = 472), b) single-session class (n = 163), and c) four-session class (n = 207). While self-help group only received educational materials, curriculum for other arms was built on the social cognitive, motivational interviewing, and trans-theoretical- frameworks. Participants could also receive nicotine replacement therapy (NRT). Outcome was self-reported smoking cessation measured 12 weeks after completion of the intervention, validated by exhaled carbon monoxide (CO) test. Results: Quit rate was statistically different across groups, with highest quit rate in four-session and lowest quit rate in self-help arm. Cessation rates at follow up (12 weeks after completion of the intervention) were 2.3% in the self-help arm, 6.1% in the single-session arm and 13.0% in the four-session arm. Conclusion: While theory-based smoking cessation services are effective for underserved populations, four-session curriculum might be superior to a single session program.

Effectiveness of a Social Marketing Mix Intervention on Changing the Smoking Behavior of Santri in Traditional Islamic Boarding Schools in Indonesia

OBJECTIVES

This study investigated the effectiveness of the social marketing mix approach in increasing students' knowledge about smoking, promoting positive attitudes toward smoking cessation, and decreasing smoking behavior.

METHODS

This quantitative research study incorporated a quasi-experimental method with a pretest-posttest non-equivalent group design. Using the purposive sampling technique, 152 smoking students were selected as participants. They were divided into 2 equal groups, with 76 students in the control group and 76 in the intervention group. The data were collected using questionnaires and analyzed with the chi-square test, independent t-test, Wilcoxon signed-rank test, and Mann-Whitney U-test.

RESULTS

The social marketing mix intervention was effective in increasing the students' knowledge about smoking (p<0.001), improving their attitude toward smoking cessation (p<0.001), and reducing their smoking behavior (p=0.014).

CONCLUSIONS

This approach should be implemented by local governments to reduce smoking behavior in the community, especially among teenagers, in addition to instituting a smoking ban and applying fines.

Academic Achievements, Satisfaction with Studies and Risky Behaviours among First-Year Students of Kaunas (Lithuania) Universities, 2000-2017

Risky behaviours are prevalent among university students and may affect academic achievements. This study aimed to evaluate the associations between academic achievements, satisfaction with studies and risky behaviours among first-year students of Kaunas (Lithuania) universities. Three cross-sectional surveys were conducted in 2000, 2010, and 2017. The self-administered questionnaires were filled in during lectures and assessed frequency and amount of alcohol consumption, drinking problems (CAGE test), smoking and drug use frequency, and academic achievements. The associations between risky behaviours and academic achievements were analysed using multivariable logistic regression analysis. Altogether 3325 students (1341 men and 1984 women) aged 20.0 (1.5) years participated in the survey. The proportion of students who consumed alcohol at least once a week and drank 11 or more standard alcoholic units (SAU) a week decreased. Every fifth student reported a drinking problem. Daily smoking prevalence declined, and drug use increased among male students. Multivariable logistic regression analysis revealed that frequent alcohol consumption and problem drinking were associated with low importance of good grades. Students who rated their academic performance below average and were dissatisfied with studies were more likely to consume ≥11 SAU a week. Daily smoking was more common among students who reported low importance of good grades and academic performance below average. A higher prevalence of drug use was found only in male students who declared low importance of good grades. Health promoting interventions at the individual and student community level are required to reduce the prevalence of substance use and improve the academic achievements of students.

Smoking, life expectancy, and chronic disease in South Korea, Singapore, and the United States: A microsimulation model

The substantial social and economic burden attributable to smoking is well-known, with heavy smokers at higher risk of chronic disease and premature mortality than light smokers and nonsmokers. In aging societies with high rates of male smoking such as in East Asia, smoking is a leading preventable risk factor for extending lives (including work-lives) and healthy aging. However, little is known about whether smoking interventions targeted at heavy smokers relative to light smokers lead to disproportionately larger improvements in life expectancy and prevalence of chronic diseases and how the effects vary across populations. Using a microsimulation model, we examined the health effects of smoking reduction by simulating an elimination of smoking among subgroups of smokers in South Korea, Singapore, and the United States. We found that life expectancy would increase by 0.2 to 1.5 years among light smokers and 2.5 to 3.7 years among heavy smokers. Whereas both interventions led to an increased life expectancy and decreased the prevalence of chronic diseases in all three countries, the life-extension benefits were greatest for those who would otherwise have been heavy smokers. Our findings illustrate how smoking interventions may have significant economic and social benefits, especially for life extension, that vary across countries.

Changes in Cardiovascular Risk Factors in Residents of the Siberian Region (According to Epidemiological Studies)

Aim. To analyze prevalence of cardiovascular risk factors in the Kemerovo region based on the results of epidemiological studies (2013 and 2016).

Material and methods. The study was based on two large epidemiological studies of the Kemerovo region: on 2013, «The epidemiology of cardiovascular diseases and their risk factors in the Russian Federation» and on 2016, «The prospective study of urban and rural epidemiology: study of the influence of social factors on chronic non-infectious diseases in low, middle and high income countries». In the study we analyzed cardiovascular risk factors using identical questionnaires, functional, anthropometric, biochemical means and measured on identical scales. As a result, we analyzed the prevalence of smoking, diabetes mellitus, overweight and obesity, abdominal obesity, hypercholesterolemia and hypertriglyceridemia, high levels of low-density lipoprotein (LDL).

Results. Univariate analysis indicates that in the sample of 2016, compared to the sample of 2013, the prevalence of smoking is statistically significantly lower, as well as the proportion of participants with high cholesterol levels, but not taking lipid-lowering drugs. In contrast, the prevalence of diabetes, hypercholesterolemia and hypertriglyceridemia is higher. In women, the frequency of abdominal obesity on 2016 is lower than on 2013: at 35-44 age group odds ratio (OR) =0.67 with 95% confidence interval (CI) 0.44-1.03, at 45-54 age group OR =0.47 with 95% CI 0.31-0.72, 55-65 age group OR =0.49 with 95% CI 0.30-0.79. A high incidence of diabetes, hypercholesterolemia and hypertriglyceridemia is characteristic mainly of older women (55-65 age group): accordingly, OR =1.96 with 95% CI 1.19-3.22, OR =1.42 with 95% CI 1,02-1.97, OR =1.51 at 95% CI 1.08-2.12. In the 45-54 age group of men, they smoked statistically significantly less often on 2016 compared to 2013, OR =0.59 with 95% CI 0.36-0.96. The prevalence of overweight and obesity in both samples is the same: for women, the OR for overweight in different age groups is within 0.74-0.87, for men - within 0.95-1.78; for obesity OR in women is from 0.70 to 0.79, in men - from 1.03 to 1.34.

Conclusion. A significant advantage of the study is the analysis of changes in prevalence in age and gender groups, which showed significant differences in the dynamics of men and women in different age categories for a number of risk factors. Analysis of the dynamics of the prevalence of cardiovascular risk factors makes it possible to assess the effectiveness of state and regional policies in the field of health protection and, first of all, "risk groups” that require closer attention, development and implementation of targeted health-saving technologies.

Smoking Cessation and Quality of Life: Insights From Analysis of Longitudinal Australian Data, an Application for Economic Evaluations

OBJECTIVES

A number of studies have shown an association between smoking habit and quality of life, but these have mainly involved cross-sectional data. This study takes advantage of longitudinal panel data to estimate the effect of the transition from "smoker" to "ex-smoker" status (smoking cessation) on health-related quality of life (HRQoL), measured by SF-36, in an Australian general population sample.

METHODS

Panel data from 13 waves (2001-2013) of a nationally representative longitudinal survey of Household Income and Labour Dynamics of Australia (HILDA) were used; 1858 respondents (5% of total HILDA sample) who experienced only 1 cessation event in their HILDA life were selected. HRQoL trajectories elicited by SF-36 (0-100 scale, worst to best health) were modeled before and after cessation events using a piecewise (segmented) 2-way fixed-effect linear regression, adopted to capture within-person differences. This enabled measurement of changes of regression slopes and intercept while controlling time-invariant characteristics (eg, country of birth, gender) and time-varying changes in health status.

RESULTS

Annual pre-post intervention improvements were estimated for the following dimensions: role physical 0.65 (95% CI 0.62-1.24), bodily pain 0.48 (95% CI 0.10-0.86), general health 0.55 (95% CI 0.2-0.9), and the physical component summary score 0.22 (95% CI 0.01-0.04). Immediate effects (discontinuity at the time of cessation) of smoking cessation existed for bodily pain -1.5 (95% CI -2.52 to -0.40) and general health 1.82 (95% CI 1.01-2.62). The effects for mental health domains were not significant.

CONCLUSIONS

Adjusting for all unmeasured time-invariant confounders and controlling the effect of time, this study revealed the varied effects of smoking cessation on HRQoL; it has positive effect on physical and general health but nonsignificant effect on mental aspects. Preference-based utility measures based on SF-6D capture changes that can be measured in several of the domains of the SF-36.

A framework for exploring non-response patterns over time in health surveys

Background

Most health surveys have experienced a decline in response rates. A structured approach to evaluate whether a decreasing - and potentially more selective - response over time biased estimated trends in health behaviours is lacking. We developed a framework to explore the role of differential non-response over time. This framework was applied to a repeated cross-sectional survey in which the response rate gradually declined.

Methods

We used data from a survey conducted biannually between 1995 and 2017 in the city of Rotterdam, The Netherlands. Information on the sociodemographic determinants of age, sex, and ethnicity was available for respondents and non-respondents. The main outcome measures of prevalence of sport participation and watching TV were only available for respondents. The framework consisted of four steps: 1) investigating the sociodemographic determinants of responding to the survey and the difference in response over time between sociodemographic groups; 2) estimating variation in health behaviour over time; 3) comparing weighted and unweighted prevalence estimates of health behaviour over time; and 4) comparing associations between sociodemographic determinants and health behaviour over time.

Results

The overall response rate per survey declined from 47% in 1995 to 15% in 2017. The probability of responding was higher among older people, females, and those with a Western background. The response rate declined in all subgroups, and a faster decline was observed among younger persons and those with a non-Western ethnicity as compared to older persons and those with a Western ethnicity. Variation in health behaviours remained constant. Prevalence estimates and associations did not follow the changes in response over time. On the contrary, the difference in probability of participating in sport gradually decreased between males and females, while no differential change in the response rate was observed.

Conclusions

Providing insights on non-response patterns over time is essential to understand whether declines in response rates may have influenced estimated trends in health behaviours. The framework outlined in this study can be used for this purpose. In our example, in spite of a major decline in response rate, there was no evidence that the risk of non-response bias increased over time.

The impact of local smoke-free policies on smoking behaviour among adults in Indonesia: a quasi-experimental national study

AIMS

To investigate to what extent the adoption of local smoke-free policies (SFPs) in Indonesia in 2007-13 was associated with changes in adult smoking behaviour.

DESIGN

A quasi-experimental study.

SETTING

Indonesia, 2007 and 2013.

PARTICIPANTS

A total of 1 052 611 > 25-year-old adults. Data were derived from the 2007 and 2013 Indonesian national health survey.

MEASUREMENTS

For both years, provincial and district SFPs were identified from government documents in 497 districts in 33 provinces. Multi-level logistic regression analysis assessed the association of adoption of provincial and district SFPs between 2007 and 2013 with smoking continuation (among ever-smokers), current smoking and high smoking intensity (among current smokers). We controlled for survey year, SFP in 2007, socio-demographics and district characteristics.

FINDINGS

Provincial SFP exposure was associated with lower odds of smoking continuation [strong SFP versus no SFP: odds ratio (OR) = 0.71, 95% confidence interval (CI) = 0.66-0.76] and smoking intensity (strong SFP: OR= 0.91, 95% CI = 0.86-0.97), but also with higher odds of current smoking (strong SFP versus no SFP: OR = 1.08; 95% CI = 1.04-1.12). District SFP exposure was associated with higher odds of smoking continuation (strong SFP versus no SFP: OR = 1.07, 95% CI = 1.01-1.14) and current smoking (strong SFP versus no SFP: OR = 1.09, 95% CI = 1.05-1.14), but with lower odds of smoking intensity (moderately strong SFP versus no SFP: OR = 0.95, 95% CI = 0.91-0.99).

CONCLUSIONS

There may be an association between the adoption of local smoke-free policies in Indonesia and decreased adult smoking intensity. However, the evidence is inconsistent, which may reflect problems with policy implementation and enforcement.

The Tobacco Control Scale as a research tool to measure country-level tobacco control policy implementation

INTRODUCTION

The Tobacco Control Scale (TCS) was designed for advocacy purposes but has also been used as a research tool. In the present study, we characterized TCS use, its limitations and strengths, and critically assessed its use as a research instrument.

METHODS

We conducted an extensive search of the biomedical databases PubMed and Web of Science for the keyword ‘tobacco control scale’ in all fields. The search was limited to studies published in the period March 2006 to December 2019. Out of 69 hits, 32 studies met the inclusion criteria. Two reviewers independently extracted information from each publication regarding their general characteristics, publication and research aspects, and the characteristics of the use of the TCS.

RESULTS

We found that researchers have used the TCS as a tool to monitor tobacco control policies mainly in cross-sectional observational studies with ecological and multilevel designs directed to advocacy and the promotion of further research. Different outcomes, such as smoking prevalence and quit ratios, have been associated with tobacco control policy scores. The main reported limitations of the TCS were a low variance across countries and a failure to express enforcement and to incorporate the most recent legislation.

CONCLUSIONS

The TCS has been commonly used to assess differences in outcomes according to tobacco control policies. However, there are still areas for improvement in its use in research regarding the lack of comparability of TCS scores across time. The lessons that have been learned should be used to adapt and expand the TCS overseas.

Smoking-Attributable Direct Healthcare Expenditure in Lithuania: A Prevalence-Based Annual Cost Approach

Introduction: The estimates of the economic burden of smoking provide the basis for a comprehensive assessment of the overall economic impact and evidence for potential public health policy intervention by the government. The aim of this paper is to estimate the smoking-attributable direct healthcare expenditure covered by the Compulsory Health Insurance Fund (CHIF) in Lithuania in 2013. Methods: A prevalence-based and disease-specific annual cost approach was applied to 25 smoking-related diseases or disease categories. Our analysis included only direct government healthcare expenditure (reimbursed by CHIF), including: smoking-attributable outpatient and inpatient care services, medical rehabilitation, reimbursable and publicly procured pharmaceuticals and medical aids, the emergency medical aid (ambulance) service, nursing, and expensive tests and procedures. The smoking-attributable expenditure on the above-mentioned healthcare services was calculated by multiplying the total annual expenditure by the corresponding smoking attributable fractions (SAFs). Results: The total smoking-attributable government expenditure amounted to €37.4 million in 2013. This represented 3% of the total CHIF budget in 2013. Smoking-attributable expenditure on inpatient care and medical rehabilitation services was two times higher for male smokers, than for female smokers. Conclusions: Smoking imposes a significant preventable financial cost within the budget of the Lithuanian healthcare system. A quantitative estimation of smoking related healthcare costs could provide an incentive for the development of smoking cessation services, with additional attention towards male smokers, as well as an important focus on smoking prevention among children and youths.

Examining Smoking Cessation in a Community-Based Versus Clinic-Based Intervention Using Community-Based Participatory Research

Tobacco use remains a major public health problem in the U.S. disproportionately affecting underserved communities. The Communities Engaged and Advocating for a Smoke-free Environment (CEASE) initiative is an intervention to address the problem using a community-based participatory research (CBPR) approach. This study compares quit rates in a peer-led community-based intervention with those achieved in a clinical setting. The intervention consisted of three Phases. Phase I (n = 404) was a clinic-based trial comparing two types of counseling. Phase II (n = 398) and Phase III (n = 163) interventions were conducted in community venues by trained Peer Motivators. Quit rates at 12-week follow-up increased from 9.4 % in Phase I (clinic-based) to an average of 23.7 % in Phases II and III combined (community-based). The main predictor of smoking cessation was delivery of services in community settings (OR 2.6, 95 % CI 1.7-4.2) while controlling for possible confounders. A community-based approach can significantly guide and improve effectiveness and acceptability of smoking cessation services designed for low-income urban populations. In addition, CBPR can result in better recruitment and retention of the participants.

Smoking prevalence differs by location of residence among Ghanaians in Africa and Europe: The RODAM study

BACKGROUND

Although the prevalence of smoking is low in Ghana, little is known about the effect of migration on smoking. Comparing Ghanaians living in their country of origin to those living in Europe offers an opportunity to investigate smoking by location of residence and the associations between smoking behaviours and migration-related factors.

METHODS

Data on a relatively homogenous group of Ghanaians living in London (n = 949), Amsterdam (n = 1400), Berlin (n = 543), rural Ghana (n = 973) and urban Ghana (n = 1400) from the cross-sectional RODAM (Research on Obesity & Diabetes in African Migrants) study were used. Age-standardized prevalence rates of smoking by location of residence and factors associated with smoking among Ghanaian men were estimated using prevalence ratios (PR: 95% CIs).

RESULTS

Current smoking was non-existent among women in rural and urban Ghana and London but was 3.2% and 3.3% in women in Amsterdam and Berlin, respectively. Smoking prevalence was higher in men in Europe (7.8%) than in both rural and urban Ghana (4.8%): PR 1.91: 95% CI 1.27, 2.88, adjusted for age, marital status, education and employment. Factors associated with a higher prevalence of smoking among Ghanaian men included European residence, being divorced or widowed, living alone, Islam religion, infrequent attendance at religious services, assimilation (cultural orientation), and low education.

CONCLUSION

Ghanaians living in Europe are more likely to smoke than their counterparts in Ghana, suggesting convergence to European populations, although prevalence rates are still far below those in the host populations.

Trends in major risk factors and mortality from main non-communicable diseases in Lithuania, 1985-2013

Background

This study aimed to assess the trends in the prevalence and levels of risk factors and mortality from main non-communicable diseases in the Lithuanian population aged 45–64 years during 1985 to 2013.

Methods

Data from four general population surveys conducted between 1985 and 2008 were used. All these surveys were carried out in Kaunas city and five randomly selected municipalities of Lithuania. Risk factors measured at each survey included regular smoking, overweight, obesity, arterial hypertension, and high levels of blood lipids. In total, data of 10,719 subjects (4,965 men and 5,754 women) aged 45–64 were analysed. Trends in standardized all-cause mortality and mortality from cardiovascular disease (CVD), coronary heart disease (CHD), and malignant neoplasms were estimated for both sexes by joinpoint regression analysis.

Results

In 1985–2013, some favourable trends were observed in the age-standardized mean levels and prevalence of risk factors and mortality from main non-communicable diseases in the Lithuanian middle-aged population. The mean values of blood lipids (with the exception of triglycerides) and the prevalence of dyslipidemias declined. In women, mean levels of systolic blood pressure and body mass index decreased, while in men, the levels of these factors increased. The prevalence of arterial hypertension and obesity increased in men. The proportion of obese women decreased. Smoking prevalence increased in both men and women. From 2007 to 2008, significant downward trends, which were steeper in women than in men, were observed in all-cause, CVD, and CHD mortality.

Conclusions

Despite the favourable changes in some risk factors and mortality rates, the prevalence of risk factors and mortality from main non-communicable diseases in Lithuania are still high. This indicates the importance of the ongoing primary and secondary prevention and optimal treatment of these diseases.

Socioeconomic Inequalities in Smoking and Smoking Cessation Due to a Smoking Ban: General Population-Based Cross-Sectional Study in Luxembourg

This study aimed to measure changes in socioeconomic inequalities in smoking and smoking cessation due to the 2006 smoking ban in Luxembourg. Data were derived from the PSELL3/EU-SILC (Panel Socio-Economique Liewen Zu Letzebuerg/European Union--Statistic on Income and Living Conditions) survey, which was a representative survey of the general population aged ≥16 years conducted in Luxembourg in 2005, 2007, and 2008. Smoking prevalence and smoking cessation due to the 2006 smoking ban were used as the main smoking outcomes. Two inequality measures were calculated to assess the magnitude and temporal trends of socioeconomic inequalities in smoking: the prevalence ratio and the disparity index. Smoking cessation due to the smoking ban was considered as a positive outcome. Three multiple logistic regression models were used to assess social inequalities in smoking cessation due to the 2006 smoking ban. Education level, income, and employment status served as proxies for socioeconomic status. The prevalence of smoking decreased by 22.5% between 2005 and 2008 (from 23.1% in 2005 to 17.9% in 2008), but socioeconomic inequalities in smoking persisted. Smoking prevalence decreased by 24.2% and 20.2% in men and women, respectively; this difference was not statistically significant. Smoking cessation in daily smokers due to the 2006 smoking ban was associated with education level, employment status, and income, with higher percentages of quitters among those with a lower socioeconomic status. The decrease in smoking prevalence after the 2006 law was also associated with a reduction in socioeconomic inequalities, including differences in education level, income, and employment status. Although the smoking ban contributed to a reduction of such inequalities, they still persist, indicating the need for a more targeted approach of smoke-free policies directed toward lower socioeconomic groups.

[Social inequalities in adolescent smoking: A cross-national perspective of the role of individual and macro-structural factors]

BACKGROUND

In an EU-funded project, we examined on the basis of international comparative analyses which factors were associated with and contributed to socioeconomic inequalities in adolescent smoking. This paper presents the results obtained and discusses their implications for policy and research.

METHODS

Analyses were based on the "Health Behaviour in School-aged Children (HBSC)" study in 2006 and included more than 50,000 adolescents from 37 countries. The focus was on the association between family affluence and weekly smoking (regularly, at least once a week) among adolescents. Explanatory variables at the individual level refer to psychosocial resources and burdens of school, family, and peers. At the country level, national income, various tobacco control policies, and an index of external differentiation of the educational system were used.

RESULTS

The psychosocial factors of school and family explained many of the inequalities in the smoking behavior of adolescents. In an international comparison, socioeconomic inequalities in smoking were stronger in richer countries. Absolute smoking rates were lower and inequalities in smoking smaller for boys in countries with higher tobacco prices. On the other hand, educational systems with higher degrees of external differentiation showed lower inequalities in smoking beahviour by girls, and relatively higher rates of smoking (for boys and girls). Stronger inequalities in smoking behaviour were demonstrated in countries with a greater range of preventative measures for tobacco dependence (for boys) and with higher levels of government spending on tobacco control (for girls).

CONCLUSION

Experiences in richer countries revealed that tobacco control needs to be strengthened for socially disadvantaged adolescents. The reduction of smoking prevalence and socioeconomic inequalities in smoking behavior should be based not only on a strengthening of psychosocial resources in the family and at school, but also on an increase in tobacco prices.

Association of Cigarette Prices with the Prevalence of Smoking in Korean University Students: Analysis of Effects of the Tobacco Control Policy

BACKGROUND

Increased pricing of cigarettes might be one of the most effective approaches for reducing the prevalence of smoking. This study aimed to investigate the effects of increasing cigarette prices through taxation by a tobacco intervention policy on the changes in smoking prevalence in Korean university students.

MATERIALS AND METHODS

The participants in this study were 23,047 healthy university students aged 18-29 years from a health examination in 2011-2015. We investigated the adjusted prevalence of daily and occasional smoking before and after increasing cigarette prices through taxation.

RESULTS

The prevalence of occasional smoking was significantly decreased in 2015 from 2014 in both male (from 10.7% in 2014 to 5.4%) and female (from 3.6% to 1.1%) students, but the prevalence of daily smoking did not decrease significantly. The frequency of individuals who had attempted smoking cessation during the past year was significantly higher among occasional smokers in male students (90.2%) compared with daily smokers (64.9%). For female students, there were no differences in experience of smoking cessation, willingness for smoking cessation, or E-cigarette experience between daily and occasional smokers.

CONCLUSIONS

We found that a policy of increasing cigarette prices through taxation is associated with decreases in the prevalence of occasional smokers, who have relatively lower nicotine dependence compared with individuals who smoke daily. The results of our study suggest that social support and direct intervention for smoking cessation at the community level are needed for university students alongside the pricing policy.
