Abstract

Introduction: There have been rapid expansions in heated tobacco products (HTPs) outside of Japan and the Republic of Korea. In November 2018, HTPs were first introduced in Malaysia and since then, no studies have been conducted on Malaysians' use of HTPs. This study is the first to examine the prevalence of HTP use and reasons for use among Malaysian adults who smoked cigarettes.

Methods: Data came from the 2020 ITC Malaysia Survey, a web-based survey of a nationally representative sample of adults who smoked (n=1047) aged 18 and older. They were asked on ever heard of, ever used, and currently using HTPs, and their reasons for using HTPs.

Results: Overall, 25.4% (n= 324; 95% CI:22.3%-28.7%) of Malaysians who smoked reported ever used HTPs with 6.7% (n=85; 95% CI:22.3%-28.7%) were using them daily and 8.1% (n=110; 95% CI:6.4% -10.2%) were using HTPs non-daily. Most of them (57.2%) who dual use were of aged 25-39 and 97.3% were males. Among those who smoked daily, almost half (49.3%) were also using HTP daily. Among those who used HTPs daily and non-daily, curiosity (84.2%, 95% CI:78.4%-90.0%), taste (83.2%, 95% CI:77.3%-89.1%), and appealing technology (78.5%, 95% CI:71.3%-85.6%) were the most reported reasons. Among those who used HTPs daily, curiosity was the top reason (87.9%, 95% CI:78.9%-93.4%), while among non-daily, taste good was the top reason (81.9%, 95% CI:71.9%-88.8%).

Conclusions: The very high use of HTPs among Malaysians who smoked requires continued public health surveillance that can inform the regulation of these novel tobacco products.

Abstract

This study examined quitting behavior and use of cessation aids (CAs) among Malaysian adult smokers aged ≥18 years (n = 1,047). Data were from the 2020 International Tobacco Control (ITC) Malaysia Survey were analyzed. A total of 79.9% of Malaysian smokers attempted to quit in the past 12 months and 85.2% intended to quit in the next 6 months. The most common CAs were e-cigarettes (ECs) (61.4%), medication/nicotine replacement therapies (NRTs; 51.0%), and printed materials (36.7%); the least common CA was infoline/quitline services (8.1%). Multivariable logistic regression analysis was performed to examine the association between sociodemographic variables and CAs use. Male smokers were more likely to use infoline/quitline services (adjusted odds ratio [aOR] = 3.27; P = .034). Malay smokers were more likely to use infoline/quitline services (aOR = 3.36; P = .002), ECs (aOR = 1.90; P = .004), printed materials (aOR = 1.79; P = .009), and in-person services (aOR = 1.75; P = .043). Most Malaysian smokers wanted to quit smoking. Furthermore, ECs were the most popular CAs, highlighting the need to assess the effectiveness of ECs for quitting smoking in Malaysia.

Abstract

The Malaysian government reinforced smoking restrictions at public venues to protect nonsmokers from secondhand smoke (SHS) exposure. This study examined whether smokers' reports about smoking restrictions and psychosocial beliefs were associated with quit intentions among Malaysian smokers. Data from 1047 cigarette smokers (103 females and 944 males) aged 18 and older from the 2020 International Tobacco Control (ITC) Malaysia Wave 1 Survey were analyzed with bivariate and multivariable logistic regression models. Most Malaysian smokers (85.2%) reported having quit intentions. Smoking was completely restricted in 34.8% of the nighttime venues, 85.3% of air-conditioned (AC) food and beverage (F&B) venues (restaurants, food courts, coffee shops), 87.3% of non-AC F&B, and 69.4% of indoor workplaces. Smokers who visited nighttime entertainment venues where smoking was fully restricted were less likely to have quit intentions. There was no significant association found with quit intentions for smokers who visited AC and non-AC F&B venues and indoor workplaces where smoking was fully restricted. All five psychosocial beliefs assessed, age, and education were positively associated with quit intentions. Malaysian smokers are interested in quitting and psychosocial beliefs were positively associated with quit intentions. There is a need for the Malaysian government to implement and reinforce comprehensive smoking restrictions in all public venues and indoor workplaces to protect nonsmokers from SHS exposure and to encourage smokers to think about quitting, which may influence their quit intentions.

Abstract

The ITC Malaysia Project is part of the 31-country ITC Project, of which the central objective is to evaluate the impact of tobacco control policies of the WHO Framework Convention on Tobacco Control (FCTC). This article describes the methods used in the 2020 International Tobacco Control (ITC) Malaysia (MYS1) Survey. Adult smokers and non-smokers aged ≥18 years in Malaysia were recruited by a commercial survey firm from its online panel. Survey weights, accounting for smoking status, sex, age, education, and region of residence, were calibrated to the Malaysian 2019 National Health and Morbidity Survey. The survey questions were identical or functionally similar to those used in other ITC countries. Questions included demographic measures, patterns of use, quit history, intentions to quit, risk perceptions, beliefs and attitudes about cigarettes, e-cigarettes, and heated tobacco products. Questions also assessed measures assessing the impact of tobacco demand-reduction domains of the FCTC: price/tax (Article 6), smoke-free laws (Article 8), health warnings (Article 11), education, communication and public awareness (Article 12), advertising, promotion, and sponsorship restrictions (Article 13), and support for cessation (Article 14). The total sample size was 1253 (1047 cigarette smokers and 206 non-smokers). Response rate was 11.3%, but importantly, the cooperation rate was 95.3%. The 2020 ITC MYS1 Survey findings will provide evidence on current tobacco control policies and evidence needed by Malaysian government regulatory agencies to develop new or strengthen existing tobacco control efforts that could help achieve Malaysia’s endgame, i.e. a tobacco-free nation by 2040.

Abstract

Introduction: Malaysia has the largest e-cigarette (EC) market in Southeast Asia, and it has been estimated that 17% of adult daily cigarette smokers also used ECs on a daily basis in 2020. However, few studies have examined the reasons people use ECs in Malaysia. This cross-sectional study of adult cigarette smokers from Malaysia assessed reasons for EC use and their support for key proposed EC regulations.

Material and Methods: Data are from the 2020 International Tobacco Control (ITC) Malaysia Wave 1 Survey of adult (aged ≥18 years) smokers who reported that they used ECs at least monthly (N=459 out of 1047 smokers). Weighted analyses were conducted on EC users’ reasons for using ECs and their support for various EC regulations.

Results: Smokers who used ECs at least monthly were more likely to be male, aged 25–39 years, of Malay ethnicity, married, more highly educated, and living in Peninsular Malaysia. Smokers who used ECs daily reported using ECs to reduce the number of cigarettes smoked (91.3%), pleasant taste (90.1%), to quit smoking (87.9%), and enjoyment (87.5%). Smokers who used ECs less than daily reported using ECs for their pleasant taste (weekly 89.4%, monthly 87.5%), curiosity (weekly 79.5%, monthly 88.8%), being offered EC by someone (weekly 76.3%, monthly 81.6%), and to reduce the number of cigarettes smoked (weekly 76.2%, monthly 77.6%). Smokers who also used ECs were most likely to support EC regulations requiring a minimum purchasing age (88.3%) and limiting nicotine concentration (79.6%), and least likely to support regulations banning EC fruit and candy flavors (27.1%).

Conclusions: The most prevalent reasons for using ECs in Malaysia are comparable to those of other ITC countries, including Canada, US, England, and Australia. An understanding of use patterns of ECs, especially their interaction with cigarettes, are important in developing evidence-based regulations in Malaysia.

Tobacco Induced Diseases, 20(March), 32. doi: https://doi.org/10.18332/tid/146363

Abstract

Introduction: E-cigarettes (ECs) have become increasingly common in many countries, including Malaysia. The prevalence of EC use increased in Malaysia from 0.8% in 2011 to 4.9% in 2019. Three quarters of Malaysian EC users also smoke combustible cigarettes, and the prevalence of EC use among Malaysian smokers in 2014 was consistent with the prevalence of use among smokers from Canada and the US in 2016. The purpose of this study was to estimate the prevalence of EC use among Malaysian adults aged ≥18 years in 2020 and the types of EC products and flavors used by cigarette smokers who also used ECs at least monthly.

Methods: Data came from 1253 adults aged ≥18 years who participated in the 2020 International Tobacco Control Malaysia Wave 1 Survey. Weighted descriptive statistics were used to estimate the prevalence of adults who reported ever using ECs and the prevalence who used ECs either monthly, weekly, or daily. The types of EC products and flavors used were compared by frequency of EC use among current smokers who used ECs at least monthly (n=459).

Results: Overall, 5.4% (95% CI: 3.7–7.5) of Malaysian adults reported using ECs on a daily basis in 2020. Among current cigarette smokers who used ECs daily, 81.0% (95% CI: 72.5–87.7) used nicotine in their ECs, 46.2% (95% CI: 37.8–54.7) used pre-filled ECs, and 60.4% (95% CI: 51.9–68.6) reported being somewhat/very addicted to ECs. The most common EC flavors were fruit, coffee, and menthol/ mint.

Conclusions: Continued surveillance of EC use is necessary to monitor EC use in non-tobacco using populations while longitudinal research is needed to determine the extent to which ECs are, or are not, related to quitting smoking.

Abstract

Increasing quitting among smokers is essential to reduce the population burden of smoking-related diseases. Smokers’ intentions to quit smoking are among the strongest predictors of future quit attempts. It is therefore important to understand factors associated with intentions to quit, and this is particularly important in low- and middle-income countries, where there have been few studies on quit intentions. The present study was conducted to identify factors associated with quit intentions among smokers in Malaysia. Data came from the 2020 International Tobacco Control (ITC) Malaysia Survey, a self-administered online survey of 1047 adult (18+) Malaysian smokers. Smokers who reported that they planned to quit smoking in the next month, within the next six months, or sometime beyond six months were classified as having intentions to quit smoking. Factors associated with quit intentions were examined by using multivariable logistic regression. Most smokers (85.2%) intended to quit smoking. Smokers were more likely to have quit intentions if they were of Malay ethnicity vs. other ethnicities (adjusted odds ratio (AOR) = 1.82, 95% confidence interval (CI) = 1.03–3.20), of moderate (AOR = 2.11, 95% CI = 1.12–3.99) or high level of education vs. low level of education (AOR = 1.97, 95% CI = 1.04–3.75), if they had ever tried to quit smoking vs. no quit attempt (AOR = 8.81, 95% CI = 5.09–15.27), if they received advice to quit from a healthcare provider vs. not receiving any quit advice (AOR = 3.78, 95% CI = 1.62–8.83), and if they reported worrying about future health because of smoking (AOR = 3.11, 95% CI = 1.35–7.15 (a little worried/moderately worried vs. not worried); AOR = 7.35, 95% CI = 2.47–21.83 (very worried vs. not worried)). The factors associated with intentions to quit smoking among Malaysian smokers were consistent with those identified in other countries. A better understanding of the factors influencing intentions to quit can strengthen existing cessation programs and guide the development of more effective smoking-cessation programs in Malaysia.

Socioeconomic patterns of smoking cessation behavior in low and middle-income countries: Emerging evidence from the Global Adult Tobacco Surveys and International Tobacco Control Surveys. PLOS One, 14(9), e0220223.

Abstract

Introduction: Tobacco smoking is often more prevalent among those with lower socio-economic status (SES) in high-income countries, which can be driven by the inequalities in initiation and cessation of smoking. Smoking is a leading contributor to socio-economic disparities in health. To date, the evidence for any socio-economic inequality in smoking cessation is lacking, especially in low- and middle-income countries (LMICs). This study examined the association between cessation behaviours and SES of smokers from eight LMICs.

Methods: Data among former and current adult smokers aged 18 and older came from contemporaneous Global Adult Tobacco Surveys (2008–2011) and the International Tobacco Control Surveys (2009–2013) conducted in eight LMICs (Bangladesh, Brazil, China, India, Mexico, Malaysia, Thailand and Uruguay). Adjusted odds ratios (AORs) of successful quitting in the past year by SES indicators (household income/wealth, education, employment status, and rural-urban residence) were estimated using multivariable logistic regression controlling for socio-demographics and average tobacco product prices. A random effects meta-analysis was used to combine the estimates of AORs pooled across countries and two concurrent surveys for each country.

Results: Estimated quit rates among smokers (both daily and occasional) varied widely across countries. Meta-analysis of pooled AORs across countries and data sources indicated that there was no clear evidence of an association between SES indicators and successful quitting. The only exception was employed smokers, who were less likely to quit than their non-employed counterparts, which included students, homemakers, retirees, and the unemployed (pooled AOR≈0.8, p<0.10).

Conclusion: Lack of clear evidence of the impact of lower SES on adult cessation behaviour in LMICs suggests that lower-SES smokers are not less successful in their attempts to quit than their higher-SES counterparts. Specifically, lack of employment, which is indicative of younger age and lower nicotine dependence for students, or lower personal disposable income and lower affordability for the unemployed and the retirees, may be associated with quitting. Raising taxes and prices of tobacco products that lowers affordability of tobacco products might be a key strategy for inducing cessation behaviour among current smokers and reducing overall tobacco consumption. Because low-SES smokers are more sensitive to price increases, tobacco taxation policy can induce disproportionately larger decreases in tobacco consumption among them and help reduce socio-economic disparities in smoking and consequent health outcomes.

Abstract

Although increasing taxes has been established as the most effective tobacco control policy, it is not clear whether these policies reduce cigarette consumption equally among women and men. In this study, we examine whether the association between taxation/taxation structure and cigarette consumption differs by gender. The data is from the International Tobacco Control Policy Evaluation (ITC) Projects in 17 countries. Cigarette consumption was measured by gender for each ITC country. Generalized estimating equations (GEE) were employed to investigate gender differences in the association between cigarette consumption and tax structures, while controlling for time-variant demographic characteristics such as unemployment rates, proportions of adults, and percent of female population. Tiered tax structures are associated with higher cigarette consumption among both males and females. Female smokers are more responsive to an average tax increase than male smokers. Among males, higher ad valorem share in excise taxes is associated with lower cigarette consumption, but it is not the case for females. Females may not be as responsive to the prices raised by ad valorem taxes, despite being responsive to average taxes, suggesting that smokers by gender may face different prices.

Prevalence of awareness, ever-use, and current use of nicotine vaping products (NVPs) among adult current smokers and ex-smokers in 14 countries with differing regulations on sales and marketing of NVPs: Cross-sectional findings from the ITC Project.

Abstract

Aims: This paper presents updated prevalence estimates of awareness, ever‐use, and current use of nicotine vaping products (NVPs) from 14 International Tobacco Control Policy Evaluation Project (ITC Project) countries that have varying regulations governing NVP sales and marketing.

Design, setting, participants and measurements: A cross‐sectional analysis of adult (≥18 years) current smokers and ex‐smokers from 14 countries participating in the ITC Project. Data from the most recent survey questionnaire for each country were included, which spanned the period 2013 to 2017. Countries were categorized into four groups based on regulations governing NVP sales and marketing (allowable or not), and level of enforcement (strict or weak where NVPs are not permitted to be sold): (1) most restrictive policies (MRPs): not legal to be sold or marketed with strict enforcement: Australia, Brazil, Uruguay; (2) restrictive policies (RPs): not approved for sale or marketing with weak enforcement: Canada, Malaysia, Mexico, New Zealand (NZ); (3) less restrictive policies (LRPs): legal to be sold and marketed with regulations: England, Netherlands, Republic of Korea, United States (US); (4) no regulatory policies (NRPs): Bangladesh, China, Zambia. Countries were also grouped by World Bank Income Classifications. Country‐specific weighted logistic regression models estimated adjusted NVP prevalence estimates for: awareness, ever/current use, and frequency of use (daily vs. non‐daily).

Findings: NVP awareness and use were lowest in NRP countries. Generally, ever‐ and current use of NVPs were lower in MRP countries [ever‐use: 7.1% to 48.9%; current use: 0.3% to 3.5%] relative to LRP countries [ever‐use: 38.9% to 66.6%; current use: 5.5% to 17.2%] and RP countries [ever‐use: 10.0% to 62.4%; current use: 1.4% to 15.5%]. NVP use was highest among high income countries, followed by upper‐middle income countries, and then by lower‐middle income countries.

Conclusions: With a few exceptions, awareness and use of nicotine vaping products (NVPs) varies by the strength of national regulations governing NVP sales/marketing, and by country income. In countries with no regulatory policies, use rates were very low, suggesting that there was little availability, marketing and/or interest in NVPs in these countries where smoking populations are predominantly poorer. The higher awareness and use of NVPs in high income countries with moderately (e.g., Canada, NZ) and less (e.g., England, US) restrictive policies, is likely due to the greater availability and affordability of NVPs.

Abstract

Background: Recent studies show that greater price variability and more opportunities for tax avoidance are associated with tax structures that depart from a specific uniform one. These findings indicate that tax structures other than a specific uniform one may lead to more cigarette consumption.

Objective: This paper aims to examine how cigarette tax structure is associated with cigarette consumption.

Methods: We used survey data taken from the International Tobacco Control Policy Evaluation Project in 17 countries to conduct the analysis. Self-reported cigarette consumption was aggregated to average measures for each surveyed country and wave. The effect of tax structures on cigarette consumption was estimated using generalised estimating equations after adjusting for sociodemographic characteristics, average taxes and year fixed effects.

Findings: Our study provides important empirical evidence of a relationship between tax structure and cigarette consumption. We find that a change from a specific to an ad valorem structure is associated with a 6%–11% higher cigarette consumption. In addition, a change from uniform to tiered structure is associated with a 34%–65% higher cigarette consumption. The results are consistent with existing evidence and suggest that a uniform and specific tax structure is the most effective tax structure for reducing tobacco consumption.

Abstract

Malaysia introduced graphic health warning labels (GHWLs) on all tobacco packages in 2009. We aimed to examine if implementing GHWLs led to stronger warning reactions (e.g., thinking about the health risks of smoking) and an increase in subsequent quitting activities; and to examine how reactions changed over time since the implementation of the GHWLs in Malaysia and Thailand where GHWL size increased from 50–55% in 2010. Data came from six waves (2005–2014) of the International Tobacco Control Southeast Asia Survey. Between 3,706 and 4,422 smokers were interviewed across these two countries at each survey wave. Measures included salience of warnings, cognitive responses (i.e., thinking about the health risks and being more likely to quit smoking), forgoing cigarettes, and avoiding warnings. The main outcome was subsequent quit attempts. Following the implementation of GHWLs in Malaysia, reactions increased, in some cases to levels similar to the larger Thai warnings, but declined over time. In Thailand, reactions increased following implementation, with no decline for several years, and no clear effect of the small increase in warning size. Reactions, mainly cognitive responses, were consistently predictive of quit attempts in Thailand, but this was only consistently so in Malaysia after the change to GHWLs. In conclusion, GHWLs are responded to more frequently, and generate more quit attempts, but warning wear-out is not consistent in these two countries, perhaps due to differences in other tobacco control efforts.

Impact of point-of-sale tobacco display bans in Thailand: Findings from the International Tobacco Control (ITC) Southeast Asia Survey. International Journal of Environmental Research and Public Health, 12(8), 9508-9522.

Abstract

In September 2005 Thailand became the first Asian country to implement a complete ban on the display of cigarettes and other tobacco products at point-of-sale (POS). This paper examined the impact of the POS tobacco display ban in Thailand, with Malaysia (which did not impose bans) serving as a comparison. The data came from the International Tobacco Control Southeast Asia Survey (2005–2011), a prospective cohort survey designed to evaluate the psychosocial and behavioral impacts of tobacco control policies. Main measures included smokers’ reported awareness of tobacco displays and advertising at POS. At the first post-ban survey wave over 90% of smokers in Thailand were aware of the display ban policy and supported it, and about three quarters thought the ban was effective. Noticing tobacco displays in stores was lowest (16.9%) at the first post-ban survey wave, but increased at later survey waves; however, the levels were consistently lower than those in Malaysia. Similarly, exposure to POS tobacco advertising was lower in Thailand. The display ban has reduced exposure to tobacco marketing at POS. The trend toward increased noticing is likely at least in part due to some increase in violations of the display bans and/or strategies to circumvent them.

Abstract

Antismoking mass media campaigns are known to be effective as part of comprehensive tobacco control programs in high-income countries, but such campaigns are relatively new in low- and middle-income countries and there is a need for strong evaluation studies from these regions. This study examines Malaysia's first national antismoking campaign, TAK NAK. The data are from the International Tobacco Control Malaysia Survey, which is an ongoing cohort survey of a nationally representative sample of adult smokers (18 years and older; N = 2,006). The outcome variable was quit intentions of adult smokers, and the authors assessed the extent to which quit intentions may have been strengthened by exposure to the antismoking campaign. The authors also tested whether the impact of the campaign on quit intentions was related to cognitive mechanisms (increasing thoughts about the harm of smoking), affective mechanisms (increasing fear from the campaign), and perceived social norms (increasing perceived social disapproval about smoking). Mediational regression analyses revealed that thoughts about the harm of smoking, fear arousal, and social norms against smoking mediated the relation between TAK NAK impact and quit intentions. Effective campaigns should prompt smokers to engage in both cognitive and affective processes and encourage consideration of social norms about smoking in their society.

Abstract

Objectives: Study the effects of the 2011 Malaysian minimum price law (MPL) on prices of licit and illicit cigarette brands. Identify barriers to the MPL achieving positive public health effects.

Methods: The International Tobacco Control Project's Southeast Asia survey collected information on Malaysian smokers' cigarette purchases (n=7520) in five survey waves between 2005 and 2012. Consumption-weighted comparisons of proportions tests and adjusted Wald tests were used to evaluate changes over time in violation rates of the inflation-adjusted MPL, the proportion of illicit cigarette purchases and mean prices.

Results: After the passage of the MPL, the proportion of licit brand cigarette purchases that were below the inflation-adjusted 2011 minimum price level fell substantially (before 3.9%, after 1.8%, p=0.002), while violation of the MPL for illicit brand cigarette purchases was unchanged (before 89.8%, after 91.9%, p=0.496). At the same time, the mean real price of licit cigarettes rose (p=0.006), while the mean real price of illicit cigarettes remained unchanged (p=0.134). The proportion of illicit cigarette purchases rose as well (before 13.4%, after 16.5%, p=0.041).

Discussion: The MPL appears not to have meaningfully changed cigarette prices in Malaysia, as licit brand prices remained well above and illicit brand prices remained well below the minimum price level before and after MPL's implementation. The increasing proportion of illicit cigarettes on the market may have undermined any positive health effects of the Malaysian MPL. The illicit cigarette trade must be addressed before a full evaluation of the Malaysian MPL's impact on public health can take place. The authors encourage the continued use of specific excise tax increases to reliably increase the price and decrease the consumption of cigarettes in Malaysia and elsewhere.

The lower effectiveness of text-only health warnings in China compared to pictorial warnings in Malaysia: Findings from the ITC Project. Tobacco Control, 24(Suppl 4), iv6-iv13.

Abstract

Background: In 2009, China changed its health warnings on cigarette packs from side-only text warnings to two text-only warnings on 30% of the bottom of the front and back of the pack. Also in 2009, Malaysia changed from similar text warnings to pictorial health warnings consistent with Framework Convention on Tobacco Control (FCTC) Article 11 Guidelines.

Objective: To measure the impact of the change in health warnings in China and to compare the text-only health warnings to the impact of the pictorial warnings introduced in Malaysia.

Methods: We measured changes in key indicators of warning effectiveness among a longitudinal cohort sample of smokers from Waves 1 to 3 (2006–2009) of the International Tobacco Control (ITC) China Survey and from Waves 3 to 4 (2008–2009) of the ITC Malaysia Survey. Each cohort consisted of representative samples of adult (≥18 years) smokers from six cities in China (n=6575) and from a national sample in Malaysia (n=2883). Generalised Estimating Equations (GEE) were used to examine the impact of the health warnings on subsequent changes in salience of warnings, cognitive and behavioural outcomes.

Findings: Compared to Malaysia, the weak text-only warning labels in China led to a significant change in only two of six key indicators of health warning effectiveness: forgoing cigarettes and reading the warning labels. The change to pictorial warnings in Malaysia led to significant and substantial increases in five of six indicators (noticing, reading, forgoing, avoiding, thinking about quitting).

Conclusions: The delay in implementing pictorial warnings in China constitutes a lost opportunity for increasing knowledge and awareness of the harms of cigarettes, and for motivating smokers to quit

Abstract

Background: The distribution of cigarette prices has rarely been studied and compared under different tax structures. Descriptive evidence on price distributions by countries can shed light on opportunities for tax avoidance and brand switching under different tobacco tax structures, which could impact the effectiveness of increased taxation in reducing smoking.

Objective: This paper aims to describe the distribution of cigarette prices by countries and to compare these distributions based on the tobacco tax structure in these countries.

Methods: We employed data for 16 countries taken from the International Tobacco Control Policy Evaluation Project to construct survey-derived cigarette prices for each country. Self-reported prices were weighted by cigarette consumption and described using a comprehensive set of statistics. We then compared these statistics for cigarette prices under different tax structures. In particular, countries of similar income levels and countries that impose similar total excise taxes using different tax structures were paired and compared in mean and variance using a two-sample comparison test.

Findings: Our investigation illustrates that, compared with specific uniform taxation, other tax structures, such as ad valorem uniform taxation, mixed (a tax system using ad valorem and specific taxes) uniform taxation, and tiered tax structures of specific, ad valorem and mixed taxation tend to have price distributions with greater variability. Countries that rely heavily on ad valorem and tiered taxes also tend to have greater price variability around the median. Among mixed taxation systems, countries that rely more heavily on the ad valorem component tend to have greater price variability than countries that rely more heavily on the specific component. In countries with tiered tax systems, cigarette prices are skewed more towards lower prices than are prices under uniform tax systems. The analyses presented here demonstrate that more opportunities exist for tax avoidance and brand switching when the tax structure departs from a uniform specific tax.

(2015). Awareness, trial, and current use of electronic cigarettes in 10 countries: findings from the ITC Project. International Journal of Environmental Research and Public Health, 12(5), 4631-4637.

Abstract

Background: In recent years, electronic cigarettes (e-cigarettes) have generated considerable interest and debate on the implications for tobacco control and public health. Although the rapid growth of e-cigarettes is global, at present, little is known about awareness and use. This paper presents self-reported awareness, trial and current use of e-cigarettes in 10 countries surveyed between 2009 and 2013; for six of these countries, we present the first data on e-cigarettes from probability samples of adult smokers.

Methods: A cross-sectional analysis of probability samples of adult (≥ 18 years) current and former smokers participating in the International Tobacco Control (ITC) surveys from 10 countries. Surveys were administered either via phone, face-to-face interviews, or the web. Survey questions included sociodemographic and smoking-related variables, and questions about e-cigarette awareness, trial and current use.

Results: There was considerable cross-country variation by year of data collection and for awareness of e-cigarettes (Netherlands (2013: 88%), Republic of Korea (2010: 79%), United States (2010: 73%), Australia (2013: 66%), Malaysia (2011: 62%), United Kingdom (2010: 54%), Canada (2010: 40%), Brazil (2013: 35%), Mexico (2012: 34%), and China (2009: 31%)), in self-reports of ever having tried e-cigarettes (Australia, (20%), Malaysia (19%), Netherlands (18%), United States (15%), Republic of Korea (11%), United Kingdom (10%), Mexico (4%), Canada (4%), Brazil (3%), and China (2%)), and in current use (Malaysia (14%), Republic of Korea (7%), Australia (7%), United States (6%), United Kingdom (4%), Netherlands (3%), Canada (1%), and China (0.05%)).

Conclusions: The cross-country variability in awareness, trial, and current use of e-cigarettes is likely due to a confluence of country-specific market factors, tobacco control policies and regulations (e.g., the legal status of e-cigarettes and nicotine), and the survey timing along the trajectory of e-cigarette awareness and trial/use in each country. These ITC results constitute an important snapshot of an early stage of what appears to be a rapid progression of global e-cigarette use.

Effectiveness of antismoking media messages and education among adolescents in Malaysia and Thailand: Findings from the International Tobacco Control Southeast Asia (ITC-SEA) Project. Nicotine & Tobacco Research, 15(2), 482-491.

Abstract

Introduction: Finding ways to discourage adolescents from taking up smoking is important because those who begin smoking at an earlier age are more likely to become addicted and have greater difficulty in quitting. This article examined whether anti smoking messages and education could help to reduce smoking susceptibility among adolescents in two Southeast Asian countries and to explore the possible moderating effect of country and gender.

Methods: Data came from Wave 1 of the International Tobacco Control Southeast Asia Project (ITC-SEA) survey conducted in Malaysia (n = 1,008) and Thailand (n = 1,000) where adolescents were asked about receiving antismoking advice from nurses or doctors, being taught at schools about the danger of smoking, noticing antismoking messages, knowledge of health effects of smoking, beliefs about the health risks of smoking, smoking susceptibility, and demographic information. Data were analyzed using chi-square tests and logistic regression models.

Results: Overall, significantly more Thai adolescents reported receiving advice from their nurses or doctors about the danger of smoking (p < .001), but no country difference was observed for reported antismoking education in schools and exposure to antismoking messages. Multivariate analyses revealed that only provision of antismoking education at schools was significantly associated with reduced susceptibility to smoking among female Malaysian adolescents (OR = 0.26). Higher knowledge of smoking harm and higher perceived health risk of smoking were associated with reduced smoking susceptibility among Thai female (OR = 0.52) and Malaysian male adolescents (OR = 0.63), respectively.

Conclusions: Educating adolescents about the dangers of smoking in schools appears to be the most effective means of reducing adolescents’ smoking susceptibility in both countries, although different prevention strategies may be necessary to ensure effectiveness for male and female adolescents.

Comparing the experience of regret and its predictors among smokers in four Asian countries: Findings from the ITC Surveys in Thailand, South Korea, Malaysia, and China. Nicotine & Tobacco Research, 15(10), 1663-1672.

Abstract

Introduction: Nearly all smokers in high-income Western countries report that they regret smoking (Fong, G. T., Hammond, D., Laux, F. L., Zanna, M. P., Cummings, M. K., Borland, R., & Ross, H. [2004]. The near-universal experience of regret among smokers in four countries: Findings from the International Tobacco Control Policy Evaluation Survey. Nicotine and Tobacco Research, 6, S341–S351. doi:10.1080/14622200412331320743), but no research to date has examined the prevalence of regret among smokers in non-Western, low- and middle-income countries.

Methods: Data were from the International Tobacco Control (ITC) Surveys of smokers in 4 Asian countries (China, Malaysia, South Korea, and Thailand); N = 9,738. Regret was measured with the statement: “If you had to do it over again, you would not have started smoking.”

Results: Prevalence of regret in 3 countries (South Korea = 87%, Malaysia = 77%, and China = 74%) was lower than that found by Fong et al. in the United States, Australia, Canada, and the United Kingdom (89%–90%); but was higher in Thailand (93%). These significant country differences in regret corresponded with differences in tobacco control and norms regarding smoking. The predictors of regret in the Asian countries were very similar to those in the 4 Western countries: Regret was more likely to be experienced by smokers who smoked fewer cigarettes per day, perceived greater benefits of quitting and higher financial costs of smoking, had more prior quit attempts, worried that smoking would damage their health, and felt that their loved ones and society disapproved of smoking. Regret was also positively associated with intentions to quit (r = 0.23, p < .001).

Conclusions: Across the Asian countries and high-income Western countries, the prevalence of regret varies, but the factors predicting regret are quite consistent. Regret may be an important indicator of tobacco control and is related to factors associated with future quitting.

Abstract

Background: We examined the impact of cigarette pack warning labels on interest in quitting and subsequent quit attempts among adult smokers in Malaysia and Thailand.

Methods: Two overlapping cohorts of adults who reported smoking factory- made cigarettes from Malaysia and Thailand were interviewed face-to-face (3189 were surveyed at baseline and 1781 recontacted at Wave 2; 2361 current smokers were surveyed at Wave 2 and 1586 re-contacted at Wave 3). In Thailand at baseline, large text only warnings were assessed, while at Wave 2 new large graphic warnings were assessed. In Malaysia, during both waves small text only warnings were in effect. Reactions were used to predict interest in quitting, and to predict making quit attempts over the following inter-wave interval.

Results: Multivariate predictors of “interest in quitting” were comparable across countries, but predictors of quit attempts varied. In both countries, cognitive reactions to warnings (adjusted ORs; 1.57 & 1.69 for Malaysia at wave 1 and wave 2 respectively and 1.29 & 1.19 for Thailand at wave 1 and wave 2 respectively), forgoing a cigarette (except Wave 2 in Malaysia) (adjusted ORs; 1.77 for Malaysia at wave 1 and 1.54 & 2.32 for Thailand at wave 1 and wave 2 respectively), and baseline knowledge (except wave 2 in both countries) (adjusted ORs; 1.71 & 1.51 for Malaysia and Thailand respectively) were positively associated with interest in quitting at that wave. In Thailand only, “cognitive reactions to warnings” (adjusted ORs; 1.12 & 1.23 at wave 1 and wave 2 respectively), “forgoing a cigarette” (adjusted OR = 1.55 at wave 2 only) and “an interest in quitting” (adjusted ORs; 1.61 & 2.85 at wave 1 and wave 2 respectively) were positively associated with quit attempts over the following inter-wave interval. Salience was negatively associated with subsequent quit attempts in both Malaysia and Thailand, but at Wave 2 only (adjusted ORs; 0.89 & 0.88 for Malaysia and Thailand respectively).

Conclusion: Warnings appear to have common mechanisms for influencing quitting regardless of warning strength. The larger and more informative Thai warnings were associated with higher levels of reactions predictive of quitting and stronger associations with subsequent quitting, demonstrating their greater potency.

Time perspective as a predictor of smoking status: Findings from the International Tobacco Control (ITC) Surveys in Scotland, France, Germany, China, and Malaysia. BioMed Central Public Health, 13(1), 346.

Abstract

Background: Prior studies have demonstrated that time perspective—the propensity to consider shortversus long-term consequences of one’s actions—is a potentially important predictor of health-related behaviors, including smoking. However, most prior studies have been conducted within single highincome countries. The aim of this study was to examine whether time perspective was associated with the likelihood of being a smoker or non-smoker across five countries that vary in smoking behavior and strength of tobacco control policies.

Methods: The data were from the International Tobacco Control (ITC) Surveys in five countries with large probability samples of both smokers (N=10,341) and non-smokers (N=4,955): Scotland, France, Germany, China, and Malaysia. The surveys were conducted between 2005 and 2008. Survey respondents indicated their smoking status (smoker vs. non-smoker) and time perspective (future oriented vs. not future-oriented) and provided demographic information.

Results: Across all five countries, non-smokers were significantly more likely to be future-oriented (66%) than were smokers (57%), χ2 (1, N = 15,244) = 120.64, p < .001. This bivariate relationship between time perspective and smoking status held in a multivariate analysis. After controlling for country, age, sex, income, education, and ethnicity (language in France), those who were future-oriented had 36% greater odds of being a non-smoker than a smoker (95% CI: 1.22 to 1.51, p<.001).

Conclusion: These findings establish time perspective as an important predictor of smoking status across multiple countries and suggest the potential value of incorporating material to enhance future orientation in smoking cessation interventions.

Abstract

Background: This paper prospectively examined two kinds of social normative beliefs about smoking, secular versus religious norms.

Purpose: The purpose of this paper is to determine the relative importance of these beliefs in influencing quitting behaviour among Muslim Malaysian and Buddhist Thai smokers.

Methods: Data come from 2,166 Muslim Malaysian and 2,463 Buddhist Thai adult smokers who participated in the first three waves of the International Tobacco Control Southeast Asia project. Respondents were followed up about 18 months later with replenishment. Respondents were asked at baseline about whether their society disapproved of smoking and whether their religion discouraged smoking, and those recontacted at follow-up were asked about their quitting activity.

Results: Majority of both religious groups perceived that their religion discouraged smoking (78% Muslim Malaysians and 86% Buddhist Thais) but considerably more Buddhist Thais than Muslim Malaysians perceived that their society disapproved of smoking (80% versus 25%). Among Muslim Malaysians, religious, but not societal, norms had an independent effect on quit attempts. By contrast, among the Buddhist Thais, while both normative beliefs had an independent positive effect on quit attempts, the effect was greater for societal norms. The two kinds of normative beliefs, however, were unrelated to quit success among those who tried.

Conclusions: The findings suggest that religious norms about smoking may play a greater role than secular norms in driving behaviour change in an environment, like Malaysia where tobacco control has been relatively weak until more recently, but, in the context of a strong tobacco control environment like Thailand, secular norms about smoking become the dominant force.

Cessation assistance reported by smokers in 15 countries participating in the International Tobacco Control (ITC) Policy Evaluation Survey. Addiction, 107(1), 197-205.

Abstract

Aims: To describe some of the variability across the world in levels of quit smoking attempts and use of various forms of cessation support.

Design: Use of the International Tobacco Control Policy Evaluation Project surveys of smokers, using the 2007 survey wave (or later, where necessary).

Settings: Australia, Canada, China, France, Germany, Ireland, Malaysia, Mexico, the Netherlands, New Zealand, South Korea, Thailand, United Kingdom, Uruguay and United States.

Participants: Samples of smokers from 15 countries.

Measurements: Self-report on use of cessation aids and on visits to health professionals and provision of cessation advice during the visits.

Findings: Prevalence of quit attempts in the last year varied from less than 20% to more than 50% across countries. Similarly, smokers varied greatly in reporting visiting health professionals in the last year (<20% to over 70%), and among those who did, provision of advice to quit also varied greatly. There was also marked variability in the levels and types of help reported. Use of medication was generally more common than use of behavioural support, except where medications are not readily available.

Conclusions: There is wide variation across countries in rates of attempts to stop smoking and use of assistance with higher overall use of medication than behavioural support. There is also wide variation in the provision of brief advice to stop by health professionals.

Using cognitive interviewing and behavioral coding to determine measurement equivalence across linguistic and cultural groups: An example from the International Tobacco Control Policy Evaluation Project.

Abstract

This study examined and compared results from two questionnaire pretesting methods (i.e., behavioral coding and cognitive interviewing [CI]) to assess systematic measurement bias in survey questions for adult smokers across six countries (United States, Australia, Uruguay, Mexico, Malaysia, and Thailand). Protocol development and translation involved multiple bilingual partners in each linguistic/cultural group. The study was conducted with convenience samples of 20 adult smokers in each country. Behavioral coding and CI methods produced similar conclusions regarding measurement bias for some questions; however, CI was more likely to identify potential response errors than behavioral coding. Coordinated qualitative pretesting of survey questions (or postsurvey evaluation) is feasible across cultural groups and can provide important information on comprehension and comparability. The CI appears to be a more robust technique than behavioral coding, although combinations of the two might be even better.
