    BACKGROUND: Lack of awareness among ex-smokers on the benefits of sustaining smoking cessation may be the main cause of their smoking relapse. This study explored health-related quality of life (HRQoL) and hospital admission amongst chronic obstructive pulmonary disease (COPD) patients according to the duration of smoking cessation.
    MATERIALS AND METHODS: This study recruited COPD patients from a chest clinic who agreed to participate in a medication therapy-adherence program from January to June 2013. They were interviewed during their visits to obtain information regarding their smoking history and HRQoL. They were divided into three groups according to smoking status (sustained quitters, quit ≥5 years; quitters, quit <5 years; and smokers, smoking at least one cigarette/day). The effects of the duration of cessation on HRQoL and hospital admission were analyzed using a multinomial logistic model.
    RESULTS: A total of 117 participants with moderate COPD met the inclusion criteria, who were comprised of 41 sustained quitters, 40 quitters, and 36 smokers. Several features were similar across the groups. Most of them were married elderly men (aged >64 years) with low-to-middle level of education, who smoked more than 33 cigarettes per day and had high levels of adherence to the medication regimen. The results showed that sustained quitters were less likely to have respiratory symptoms (cough, phlegm and dyspnea) than smokers (odds ratio 0.02, confidence interval 0-0.12; P<0.001). The hospital admission rate per year was increased in quitters compared to smokers (odds ratio 4.5, confidence interval 1.91-10.59; P<0.005).
    CONCLUSION: A longer duration of quitting smoking will increase the benefits to COPD patients, even if they experience increased episodic respiratory symptoms in the early period of the cessation. Thus, the findings of this study show the benefits of early smoking cessation.

    Smoking deception is often ignored, but is important in health care. In this trial it was assessed at both study entry and outcome. At study entry, 1,044 males at a primary care clinic were asked smoking status and tested for breath carbon monoxide (CO). Of self-reported non-smokers, 57/402 (14%) were actually smokers, as were 59/251 (24%) of self-reported ex-smokers. The self-reported smokers (n=387) entered a randomized, controlled trial where the intervention comprised four questions on knowledge and beliefs about smoking, standardized verbal advice against smoking, and a leaflet. At follow-up, subjects were also questioned about beliefs. Follow-up was difficult, but 191/387 (49%) attended at three or six months. Of 27 who claimed to have quit, 6 (22%) were deceivers and 21 were confirmed quitters. Cessation did not differ between intervention and control groups. Overall confirmed cessation at six months was 16/387 (4.1 %). Confirmed quitters were significantly lighter smokers than deceivers and still smokers. There were non-significant trends between the outcome groups whereby deceivers had least knowledge and most lay beliefs, and quitters had most knowledge and fewest lay beliefs. The lay beliefs may prevent some smokers from quitting.

    Assistant environmental health officers (AEHO) are health care providers (HCPs) who act as enforcers, educators and trusted role models for the public. This is the first study to explore smoking behaviour and attitudes toward tobacco control among future HCPs. Almost 30% of AEHO trainees did not know the role of AEHOs in counselling smokers to stop smoking, but 91% agreed they should not smoke before advising others not to do so. The majority agreed that tobacco control regulations may be used as a means of reducing the prevalence of smoking. Future AEHOs had positive attitudes toward tobacco regulations but lacked understanding of their responsibility in tobacco control measures.

    Physicians should play a leading role in combatting smoking; information on attitudes of future physicians towards tobacco control measures in a middle-income developing country is limited. Of 310 future physicians surveyed in a medical school in Malaysia, 50% disagreed that it was a doctor's duty to advise smokers to stop smoking; 76.8% agreed that physicians should not smoke before advising others not to smoke; and 75% agreed to the ideas of restricting the sale of cigarettes to minors, making all public places smoke-free and banning advertising of tobacco-related merchandise. Future physicians had positive attitudes towards tobacco regulations but had not grasped their responsibilities in tobacco control measures.

    This study examined support for and reported compliance with smoke-free policy in air-conditioned restaurants and other similar places among adult smokers in Malaysia and Thailand. Baseline data (early 2005) from the International Tobacco Control Southeast Asia Survey (ITC-SEA), conducted face-to-face in Malaysia and Thailand (n = 4005), were used. Among those attending venues, reported total smoking bans in indoor air-conditioned places such as restaurants, coffee shops, and karaoke lounges were 40% and 57% in Malaysia and Thailand, respectively. Support for a total ban in air-conditioned venues was high and similar for both countries (82% Malaysian and 90% Thai smokers who believed there was a total ban), but self-reported compliance with bans in such venues was significantly higher in Thailand than in Malaysia (95% vs 51%, P < .001). As expected, reporting a ban in air-conditioned venues was associated with a greater support for a ban in such venues in both countries.

    OBJECTIVE: To test whether differences of history and strength in tobacco control policies will influence social norms, which, in turn, will influence quit intentions, by influencing smokers' regret and rationalization.
    DESIGN: The data were from the International Tobacco Control (ITC) Policy Evaluation Southeast Asia Survey, a cohort survey of representative samples of adult smokers in Thailand (N = 2,000) and Malaysia (N = 2,006). The survey used a stratified multistage sampling design.
    MAIN OUTCOME MEASURES: Measures included regret, rationalization, social norms, and quit intention.
    RESULTS: Thai smokers were more likely to have quit intentions than Malaysian smokers. This difference in quit intentions was, in part, explained by the country differences in social norms, regret, and rationalization. Reflecting Thailand's history of stronger tobacco control policies, Thai smokers, compared with Malaysian smokers, perceived more negative social norms toward smoking, were more likely to regret, and less likely to rationalize smoking. Mediational analyses revealed that these differences in social norms, accounted, in part, for the country-quit intention relation and that regret and rationalization accounted, in part, for the social norm-quit intention relation.
    CONCLUSION: The results suggest that social norms toward smoking, which are shaped by tobacco control policies, and smokers' regret and rationalization influence quit intentions

    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.

    As a signatory to the World Health Organisation 2003 Framework Convention on Tobacco Control, Malaysia has policies in place and funded 300 public Quit clinics. Unfortunately, government dentists are not included to run tobacco dependence treatment. A cross-sectional exploratory survey was carried out to seek Malaysian dentists' opinion on their knowledge, perception and willingness to conduct tobacco dependence treatment. Participation was voluntary from those who attended a specially designed one-day, four-module workshop on tobacco cessation intervention. Data were collected using the Audience-Response-System equipment which tracked immediate responses covering four domains namely: smoking as a public health problem, smoking as an addiction, the role of dentists in the programme and confidence in conducting smoking cessation in the clinic. Sample comprised more female dentists (73.5%), mean age 33.6 (SD 8.99) years and with more than 3 years working experience. Findings indicated that the majority agreed Malaysia has a rising problem in the prevalence of smoking (71.6%) and predicted that it will affect mostly the young (81.9%). Only half of the dentists surveyed (58.9%) routinely recorded their patients' smoking habits. The majority (71.6%) believed that dentists are effective in helping their patient to stop smoking and 76.3% agreed that dentists should discuss the smoking habit with their patients; however, 60% agreed that doing so is too time consuming. In addition, only 24.7% knew of more ways to treat a smoking habit. The majority felt comfortable giving advice to patients about changing their habits (76.5%) or discussing treatment options (60.5%): 75% would opt for a combined programme of counselling and use of medication if they have to do, 15% would choose to go on counselling only, while 8% did not want to treat. In conclusion, the findings suggest that dentists have a strong potential to contribute significantly to providing smoking cessation treatment if adequately trained.

    BACKGROUND: There is an unclear relationship between smoker's early motivation and success rates. Here we aimed to explore the correlates of motivation and smoking abstinence and relapse in worksite smoking cessation programmes.
    METHODS: This prospective cohort study involved employees from two major public universities in Malaysia. Participants were actively recruited into a smoking cessation programme. At the start of treatment, participants were administered a questionnaire on sociodemographic variables, smoking habits and 'stage of change'. Behaviour therapy with free nicotine replacement therapy (NRT) was given as treatment for two months. A similar stage of change questionnaire was given at six months, and their smoking status was determined.
    RESULTS: There were 185 smokers from both Universities, who joined the programme. At six months, 24 smokers reported sustained abstinence while the others had relapsed. Prior to the programme, the majority of smokers were seriously planning on quitting (59.5%--preparation stage), but over a third had no plans to quit (35.5%--contemplation stage). There was no significant difference noted in changes of motivation stage among the relapsers and the non quitters. In addition, logistic regression showed that sustained abstinence was not predicted by pre-session motivation stage, but this did predict higher relapse for the participants, compared to those in the preparation stage.
    CONCLUSION: It is possible to help smokers in the lower motivation groups to quit, provided extra caution is taken to prevent relapse. Healthcare providers' recruitment strategies for cessation programmes should thus encompass smokers in all motivation stages.

    A wide range of cigarette prices can undermine the impact of tobacco tax policy when smokers switch to cheaper cigarettes instead of quitting. In order to better understand this behaviour, we study socio-economic determinants of price/brand choices in two different markets: a semi-monopolistic market in Thailand and a competitive market in Malaysia. The hypothesis that the factors affecting the price/brand choice are different in these two markets is analysed by employing a 2005 survey among smokers. This survey provides a unique perspective on market characteristics usually described only in business reports by the tobacco industry. We found that smokers in Thailand have fewer opportunities to trade down to save money on cigarettes, but pay lower prices than smokers in Malaysia, despite Thailand's higher tax rate. The Malaysian market, on the other hand, offers many possibilities to shop around for cheaper cigarettes. Higher income and education increase the price paid per cigarette in both countries, but the impact of these factors is larger in Malaysia. This has implications for sensitivity to cigarette prices. Using tax policy alone should be a more effective tobacco control measure in Thailand as compared to Malaysia. The effectiveness of a tax increase in Malaysia can be improved by adding programmes focusing on smoking cessation among low-income/low-educated smokers.

    In the wake of the World Health Organization Framework Convention on Tobacco Control, corporate social responsibility (CSR) is among the few remaining mechanisms for tobacco corporations publicly to promote their interests. Health advocates may be unaware of the scale, nature and implications of tobacco industry CSR. This investigation aimed to construct a typology of tobacco industry CSR through a case study of the evolution and impact of CSR activities of a particular tobacco corporation in one country - British American Tobacco, Malaysia (BATM), the Malaysian market leader. Methods included searching, compiling and critically appraising publicly available materials from British American Tobacco, BATM, published literature and other sources. The study examined BATM's CSR strategy, the issues which it raises, consequences for tobacco control and potential responses by health advocates. The investigation found that BATM's CSR activities included assistance to tobacco growers, charitable donations, scholarships, involvement in anti-smuggling measures, 'youth smoking prevention' programs and annual Social Reports. BATM has stated that its model is predominantly motivated by social and stakeholder obligations. Its CSR activities have, however, had the additional benefits of contributing to a favourable image, deflecting criticism and establishing a modus vivendi with regulators that assists BATM's continued operations and profitability. It is imperative that health advocates highlight the potential conflicts inherent in such arrangements and develop strategies to address the concerns raised.

    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.

    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.

    OBJECTIVE: To investigate the impact of smoking and smoking cessation on cardiovascular mortality, acute coronary events, and stroke events in people aged 60 and older, and to calculate and report risk advancement periods for cardiovascular mortality in addition to traditional epidemiological relative risk measures.

    DESIGN: Individual participant meta-analysis using data from 25 cohorts participating in the CHANCES consortium. Data were harmonised, analysed separately employing Cox proportional hazard regression models, and combined by meta-analysis.

    RESULTS: Overall, 503,905 participants aged 60 and older were included in this study, of whom 37,952 died from cardiovascular disease. Random effects meta-analysis of the association of smoking status with cardiovascular mortality yielded a summary hazard ratio of 2.07 (95% CI 1.82 to 2.36) for current smokers and 1.37 (1.25 to 1.49) for former smokers compared with never smokers. Corresponding summary estimates for risk advancement periods were 5.50 years (4.25 to 6.75) for current smokers and 2.16 years (1.38 to 2.39) for former smokers. The excess risk in smokers increased with cigarette consumption in a dose-response manner, and decreased continuously with time since smoking cessation in former smokers. Relative risk estimates for acute coronary events and for stroke events were somewhat lower than for cardiovascular mortality, but patterns were similar.

    CONCLUSIONS: Our study corroborates and expands evidence from previous studies in showing that smoking is a strong independent risk factor of cardiovascular events and mortality even at older age, advancing cardiovascular mortality by more than five years, and demonstrating that smoking cessation in these age groups is still beneficial in reducing the excess risk.

    OBJECTIVE: To identify the relationship between knowledge, attitude and perception regarding environmental tobacco smoke (ETS) and smoking among Malaysian adolescents living in states with complete or partial smoke-free legislation (SFL).
    METHODS: A total of 898 respondents aged 13-14 years were randomly selected from 21 secondary schools. The Malay version of the modified Global Youth Tobacco Survey questionnaire was used. Hierarchical logistic regression was performed in examining predictors of smoking attempt among adolescents.
    RESULTS: Participants exposed to ETS >5 h/day were more likely to have smoked compared to those exposed to ETS <1 h/day (OR 4.1, 95%CI 1.03-16.0). Living in a state with partial SFL was associated with a two-fold increase in self-reported smoking attempts (OR 1.95, 95%CI 1.10-3.43) compared to living in a state with complete SFL. Negative attitudes and perceptions towards smoking and ETS exposure were linked to lower smoking attempts in states with complete SFL.
    CONCLUSIONS: Adolescents with limited ETS exposure who lived in a state with complete SFL were less likely to attempt smoking compared to those exposed more regularly to ETS and living in a state with partial SFL. Preventing adolescents from becoming smokers is the key to reducing national prevalence rates in smoking. There is a need to implement comprehensive smoke-free legislation nationally across Malaysia.

    Decades of research have produced overwhelming evidence that tobacco taxes reduce tobacco use and increase government tax revenue. The magnitude and effectiveness of taxes in reducing tobacco use provide an incentive for tobacco users, manufacturers and others, most notably criminal networks, to devise ways to avoid or evade tobacco taxes. Consequently, tobacco tax avoidance and tax evasion can reduce the public health and fiscal benefit of tobacco taxes.

    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.
