    BACKGROUND:
    Tobacco consumption (TC) among youths poses significant public health problem in developing countries. This study utilized the data of Global Youth Tobacco Survey (GYTS), 2007 to examine and compare youth TC behavior in Bangladesh, Nepal and Sri Lanka.

    METHODS:
    The GYTS covered a total of 2,242 Bangladeshi, 1,444 Nepalese and 1,377 Sri-Lankan youths aged 13-15 years. They represented response rates of 88.9%, 94.6%, and 85.0% for the three countries, respectively. Socioeconomic, environmental, motivating, and programmatic predictors of TC were examined using cross tabulations and logistic regressions.

    RESULTS:
    Prevalence of TC was 6.9% (9.1% in males, 5.1% in females) in Bangladesh, 9.4% (13.2% in males, 5.3% in females) in Nepal and 9.1% (12.4% in males, 5.8% in females) in Sri Lanka. The average tobacco initiation age was 9.6, 10.24 and 8.61 years, respectively. Cross tabulations showed that gender, smoking among parents and friends, exposure to smoking at home and public places, availability of free tobacco were significantly (P < 0.001) associated with TC in all three countries. The multivariable analysis [odds ratio (95% confidence interval)] indicated that the common significant predictors for TC in the three countries were TC among friends [1.9 (1.30-2.89) for Bangladesh, 4.10 (2.64-6.38) for Nepal, 2.34 (1.36-4.02) for Sri Lanka], exposure to smoking at home [1.7 (1.02-2.81) for Bangladesh, 1.81 (1.08-2.79) for Nepal, 3.96 (1.82-8.62) for Sri Lanka], exposure to smoking at other places [2.67 (1.59-4.47) for Bangladesh, 5.22 (2.76-9.85) for Nepal, 1.76 (1.05-2.88) for Sri Lanka], and the teaching of smoking hazards in schools [0.56 (0.38-0.84) for Bangladesh, 0.60 (0.41-0.89) for Nepal, 0.58 (0.35-0.94) for Sri Lanka].

    CONCLUSIONS:
    An understanding of the influencing factors of youth TC provides helpful insights for the formulation of tobacco control policies in the South-Asian region.

    The objective of this research was to compare the response of adult smokers in Malaysia to newly proposed pictorial cigarette warnings against the current text-only warnings. The study population included 140 adult male smokers who were enrolled in a randomized trial to view either the new pictorial warnings (intervention) or the old text-only warnings (control). Participants completed pre-exposure and post-exposure questionnaires that assessed their awareness of the health risks of smoking, response to the package warnings, and interest in quitting smoking. Exposure to the pictorial warnings resulted in increased awareness of the risks of smoking, stronger behavioral response to the warnings and increased interest in quitting smoking. The new warnings in Malaysia will increase smokers' knowledge of the adverse health effects of smoking and have a positive effect on interest in quitting.

    A study was undertaken to 1) determine the effects of tobacco smoke exposure on maternal and neonatal weight and body mass index (BMI) and placental weight, volume and surface area and 2) establish any correlations between the placental surface area, volume and weight with maternal and neonatal body weight and BMI in mothers exposed to cigarette smoke. A total of 154 full-term placentae, 65 from mothers exposed to tobacco smoke and 89 from non-exposed mothers were collected from Kuala Lumpur Maternity Hospital. The placental surface area was determined using a stereological grid, the volume by Scherle's method and the weight by using an electronic weighing machine. In general there were no differences in maternal, placental and neonatal parameters between the exposed and non-exposed groups. However, there were significant correlations between placental weight with maternal weight and maternal BMI in both exposed (r = 0.315; p = 0.013) and (r = 0.265; p = 0.038), and non-exposed (r = 0.224; p = 0.035) and (r = 0.241; p = 0.023) mothers. It was also found that the maternal weight on admission correlated significantly with placental weight in both Malay (r = 0.405; p = 0.020) and Indian (r = 0.553; p = 0.050) passive smokers. Correcting the placental parameters for the maternal weight had no effect on the results.

    OBJECTIVE: To explore tobacco industry accounts of its use of indirect tobacco advertising and trademark diversification (TMD) in Malaysia, a nation with a reputation for having an abundance of such advertising.
    METHODS: Systematic keyword and opportunistic website searches of formerly private tobacco industry internal documents made available through the Master Settlement Agreement.
    RESULTS: 132 documents relevant to the topic were reviewed. TMD efforts were created to advertise cigarettes after advertising restrictions on direct advertising were imposed in 1982. To build public credibility the tobacco companies set up small companies and projected them as entities independent of tobacco. Each brand selected an activity or event such as music, travel, fashion, and sports that best suited its image. RJ Reynolds sponsored music events to advertise its Salem brand while Philip Morris used Marlboro World of Sports since advertising restrictions prevented the use of the Marlboro man in broadcast media. Despite a ban on tobacco advertisements in the mass media, tobacco companies were the top advertisers in the country throughout the 1980s and 1990s. The media's dependence on advertising revenue and support from the ruling elite played a part in delaying efforts to ban indirect advertising.
    CONCLUSION: Advertising is crucial for the tobacco industry. When faced with an advertising ban they created ways to circumvent it, such as TMDs.

    A longitudinal study was conducted to determine changes in knowledge, attitudes and preventive efforts of Malaysian medical students concerning cigarette smoking and environmental exposure to tobacco smoke from their first pre-clinical year in medical school until their final clinical year. There were significant improvements in knowledge about cigarette smoking and in knowledge, attitudes and efforts concerning environmental exposure to tobacco smoke. Overall attitudes concerning cigarette smoking did not change over this period. The same pattern was found for male non-smokers. Women improved on all five scales; male smokers improved on none over the 3-year period. Male non-smokers had better scores on these scales than male smokers in both beginning and ending years. Women excelled in comparison to male non-smokers on smoking attitudes in the pre-clinical year and on all scales except preventive efforts in the final clinical year.Although medical students experienced no changes in the amount of pressures not to smoke from family and friends, there was a significant increase in the amount of prohibition on smoking from their teachers. Male non-smokers alone accounted for this increase. Women experienced more pressure than men not to smoke from their teachers in both years, but the male smokers and non-smokers did not differ in teacher pressure for either year.

    Objective: This study aims to develop, validate and determine the reliability of an interactive multimedia strategy
    to prevent tobacco use among the young (TUPY-S) from an adolescents’ perspective. Methods: A descriptive study
    design was utilized. A modular instruction guideline by Russel (1974) was followed in the entire process, comprising
    a feasibility study, a review of existing modules, specification of the objectives, identification of the construct criterion
    items, learner analysis and entry behavior specification, establishment of the sequence instruction and media selection,
    a tryout with students and a field test. Result: Feasibility was agreed among the researchers and the school authorities.
    Culturally suitable rigorously developed tobacco use preventive strategies delivered using information technology (IT)
    are lacking in the literature. The objective of TUPY-S is to prevent tobacco use among adolescents living in Malaysia.
    Identified construct criterion items include knowledge, attitude, intention to use, self-efficacy, and refusal skill. The target
    population was early adolescents belonging to generation-Z. Content was developed from the adolescents’ perspective
    and delivered using IT in Malay language. Content validity, assessed by six experts in the field and module development,
    was good at 86%. The students’ tryout showed satisfactory face validity subjectively and objectively (85.5%) and
    high alpha Cronbach reliability (0.91). Conclusion: TUPY-S was confirmed to suit early adolescents of the current
    generation living in Malaysia. It demonstrated good content validity among the experts, satisfactory face validity and
    reliability among the target population. TUPY-S is ready to be evaluated for its effectiveness among early adolescents.

    INTRODUCTION: Understanding how and where youth obtain tobacco products are major factors in the development of suitable intervention programs to reduce youth smoking. This study aimed to determine the source of cigarettes and the associated factors among Malaysian school adolescent smokers.

    METHODS: Our sample consisted of 1348 youth aged 10-17 years who were current smokers (having smoked at least once in the last 30 days). The source of cigarettes (commercial, over-the-counter purchases; or social, borrowing or obtaining from someone else) was the dependent variable, and multivariable logistic regression was employed to determine its association with independent variables (i.e. sociodemographics, smoking behavior, and knowledge of laws prohibiting sales of cigarettes to youth).

    RESULTS: Over half (54.3%) of current smokers obtained cigarettes from commercial sources, with a proportion nearly two times higher (84.2% vs 43.7%) among frequent smokers (i.e. those smoking more than 20 days per month) compared to less-frequent smokers, and among young males (56.5% vs 32.0%) compared young females. Multivariable logistic regression indicated that in urban areas, young females (AOR=12.5, 95% CI: 1.38-99.8) frequent smokers (AOR=4.41, 95% CI: 2.05-9.46), and those studying in lower (AOR=3.76, 95% CI: 1.41-10.02) and upper secondary (AOR=4.74, 95% CI: 1.72-13.06) school students were more likely to obtain cigarettes from a commercial source. On the other hand, in rural areas, only frequent smokers were more likely to get their cigarettes from commercial sources, whilst other variables were not significant.

    CONCLUSIONS: The proportion of youth smokers who obtained cigarettes from commercial sources appeared to be high, suggesting that law enforcement and health promotion activities should be enhanced to reduce the rate of smoking among Malaysian youth.

    Cadmium (Cd) and lead (Pb) are ubiquitous metals widely distributed in the environment, resulting in toxic health effects. This project aims to evaluate Pb and Cd as toxic elements in 15 different tobacco cigarette brands produced and/or sold in Selangor state, Peninsular Malaysia. The concentrations of Pb and Cd in all tobacco brands tested in this study were determined using the air-acetylene flame atomic absorption spectrophotometer (AAS). On average, the concentrations of Pb and Cd in different tobacco brand samples ranged from 3.05 and 0.80 μg/g dw, respectively. The results indicate that assessment mean values of Pb inhaled from smoking one packet of 20 cigarettes were in the range of 1.55-3.51 μg. Furthermore, the concentration of Cd inhaled per packet of cigarettes (20 sticks) is estimated to be 0.04-0.36 μg. However, there was a significant difference in the concentrations of Pb and Cd between the different brands of tobacco cigarettes, among cigarette prices (cheap versus expensive) of tobacco brands. In conclusion, cigarette smokers in Selangor, Malaysia, are heavily exposed to Pb and Cd, and such exposure could adversely affect their health in the long term. The impact of toxic heavy metals on smokers in this state would be an area for future research.

    ABSTRACTS FOR THE 1ST INTERNATIONAL BORNEO HEALTHCARE AND PUBLIC HEALTH CONFERENCE AND 4TH BORNEO TROPICAL MEDICINE AND INFECTIOUS DISEASE CONGRESS. New Frontiers in Health: Expecting the Unexpected
    Held at the Faculty of Medicine and Health Sciences, Universiti Malaysia Sabah, Kota Kinabalu, Sabah, Malaysia. 3rd-5th September 2019
    Introduction: Smoking kills 5 million people a year and it is known to cause several types of cancer and chronic diseases. Majority of smokers started smoking during adolescence and therefore preventing tobacco use among adolescents is critical to prevent them from future smoking. Our study aims to investigate the prevalence of current cigarette smoking and its associated factors among male adolescents in Malaysia.
    Methods: Data was obtained from the National Health and Morbidity Survey (NHMS): Adolescent Health Survey (AHS) 2017 which was a cross-sectional study. A two-stage stratified cluster sampling design was used to select a nationally representative sample of school-going adolescents in Malaysia. Data collection was conducted using a validated self-administered questionnaire. Multiple logistic regression analysis was performed to identify the associated factors of current cigarette smoking among male adolescents in Malaysia.
    Results: Approximately one-fifth (22.4%) of male adolescents were current cigarette smokers. Male adolescents who aged 16-17 years, from rural schools, those whose parents were widowed/ divorced/ separated, those who had either one or both parents/guardians who used tobacco product, those who were current illicit drug users and current alcohol users were more likely to be current cigarette smokers.
    Conclusion: A substantial percentage of Malaysian male adolescents were current cigarette smokers. Anti-smoking campaigns and tobacco prevention initiatives should be targeted at adolescents at risk to prevent them from becoming cigarette smokers.

    Introduction: Bidi, a leaf rolled cigarette, is the most popular form of smoking in India. Bidi cigarette contains higher tar, ammonia, and nicotine content than a conventional cigarette and is more hazardous.

    Aim of Study: The aim of this study was to determine the effect of bidi smoking on periodontitis by assessing the interleukin (IL)-1β and IL-8 from a gingival crevicular fluid (GCF).

    Materials and Methods: A total of 60 patients were selected, which included 40 patients diagnosed with chronic periodontitis (20 bidi smokers and 20 non-bidi smokers) and 20 periodontal healthy controls. Diseased and healthy sites were selected from each of the chronic periodontitis subjects. Clinical parameters assessed were plaque index (PI), gingival index (GI), periodontal probing depth (PPD), recession (RC), and clinical attachment level (CAL). Pooled GCF samples were taken from the same site and analyzed for IL-1β and IL-8 using enzyme-linked immunosorbent assay.

    Results: Bidi smokers displayed decreased levels of IL-1β and IL-8 than non-bidi smokers for both healthy and diseased sites and significantly reduced IL-8 levels among bidi smokers when compared to controls. Among bidi smokers, the diseased site had significantly higher levels of IL-8 than the healthy site. Non-smoker subjects with chronic periodontitis especially diseased sites contained significantly higher amounts of IL-1β and IL-8 than smokers and controls. The PI scores were highest among bidi smokers with reduced BOP and GI scores.

    Conclusions: Bidi smoking influenced the cytokine profile among periodontitis patients exhibiting decreased levels of IL-1β and IL-8.

    Introduction: Cigarette smoking is showing an increasing prevalence among university students nowadays. Smok- ing includes the act of smoking cigarette containing tobacco and/or other ingredients or just inhaling the cigarette smoke. Smoking has many known physical side effects that include psychological or cognitive effects. Therefore, the aim of this research is to identify the effect of cigarette smoking on the academic achievement among university students. Methods: A cross-sectional study was conducted among 136 students including 113 male and 23 fe- male aged 18 to 29 years from Management and Science University with 30 non smoker students. The question- naire included items about the social demographic characteristics, smoking status, the study styles and the aca- demic achievement of the participants. A frequency statistics, descriptive statistics and chi square test were used to analyze the collected data using SPSS version 25. Results: Among the smoker students, 51.5% came to class ear- ly, 80.8% attend classes regularly, 49.3% studied on weekends and 39.7% planned sufficient time to study for exam. Mean CGPA for smoker students is 2.6. Conclusion: Smoking is proven to be associated with low academic performance among university student.

    Background Despite country’s tobacco control law, cigarette smoking by the young people and the magnitude of nicotine dependence among the school personnel is alarming.
    Objective To determine the prevalence of smoking and to examine the determinants of smoking behaviour among the secondary school teachers in Bangladesh.
    Methods A two-stage cluster sampling was used with a selection of schools on Probability Proportional to Enrolment (PPE) size followed by stratified random sampling of government and private schools and then all the teachers present on the day of the survey were selected for the study. The 66-item questionnaire included smoking behaviour, knowledge, attitude, second-hand smoking, tobacco free school policy, cessation, media advertisement and curriculum related topics. Seven additional questions were included to assess the socio-demographic characteristics of the teachers. Data analysis was performed using SPSS 17 software. A total of 60 schools were selected with school response rate of 98.3%. An anonymous self-administered questionnaire was filled in by all teachers present at the day of the survey. The sample consisted of 559 teachers with response rate of 99.5%.
    Results The prevalence of smoking was 17% (95% CI: 14%, 20.4). About half of the teachers (48.4%) smoke daily followed by 25.3% smoke 1-2 days in last 30 days. The mean duration smoking of was 13.7(95% CI: 11.6, 15.9) years. Logistic regression analysis revealed that male teachers smoke 37.46(95% CI: 5.078, 276.432) times higher than their female counterparts. The graduate teachers were 2.179(95% 1.209, 3.926) times more likely to be smoke than master’s degree holder teachers. Smoking by friends appeared to be the strongest predictor for teachers smoking behaviour (OR 4.789, 95% CI: 1.757, 13.050). However, no statistically significant association was found between type of school, second-hand smoking and curriculum related factors and smoking behaviour of the teachers (p>0.05).
    Conclusions Prevalence of smoking among the teachers is high in Bangladesh. Effective smoking prevention program should take into account within the dominant of socio-environmental influence to reduce smoking behaviour. The school curriculum items had less impact in preventing smoking behaviour.

    Introduction: This study seeks to identify the socio-demographic and behavioral characteristics of smokers (aged 18 and above), thus develop a predicting model for tobacco abstinence receiving cessation services for tobacco dependence at the Smoking Cessation Clinics (SCC) in government Primary Health Centers in Malaysia. These predictors would improve the effectiveness and efficiency of these clinics.
    Methods : Smokers who sought smoking cessation therapy at the SCCs from 1st January 2004 to 31st
    December 2004 were chosen randomly from clinic’s registries, and 254 smokers were recruited from 8 clinics chosen through stratified random sampling. Data analyses were performed with SPSS 12.0. 17.3% of smokers attending SCCs were able to quit smoking for at least six months.
    Results : Factors significantly contributing to quitting success were elderly smokers (above 40 years old), smoked for more than 15 years, smoked less than ten sticks per day, had a previous history of quitting attempt, self referral to the clinic, high confidence level, attended SCC at least four times, each counseling session lasted for at least 30 minutes and were satisfied with the clinic service. In logistic regression model, smokers aged 40 years and above were 6.7 times more successful to quit, high level of confidence were nine times more successful, smoked more than ten sticks per day were ten times less successful, self referred smokers were ten times more successful and attending for at least 30 minutes counseling session were 12 times more successful.
    Conclusion : This study concludes that more concerted effort is needed to approach various groups of target population and SCCs clinic services need to be improved.

    Globally, one person dies every six seconds as a result of tobacco use. This makes tobacco use the cause of every one out of 10 deaths in adults and the single largest and leading cause of preventable death in the world. The objective of this study was to determine the prevalence of smoking among staff of Universiti Putra Malaysia. For the purpose of this study an analytical cross sectional study design was used and a standardized, pre-tested, while a validated well-structured questionnaire was used for data collection. The prevalence of smoking was found to be 10.0% (26.5% among males and 0.5% among females). In addition, significant associations were found between smoking and gender, religion, marital status, highest educational level, occupation, and family income (p < 0.05). In particular, gender and educational level were significant predictors of smoking. In conclusion, the prevalence of smoking among university staff was shown to be considerably lower than that stated for the national level. However, the University could aim at achieving zero prevalence in the years to come.

    Adolescent smoking is an emerging health concern in the developing countries. A cross-sectional study is conducted to determine the prevalence and smoking behaviour of adolescents in Sarawak. The prevalence of smoking is 32.8% with mean age of initiation at 12.8±1.9 years. Most (67.2%) adolescents are experimental smokers and the majority (67.9%) did not smoke on a daily basis. Branded cigarettes are preferred (83.1%) and the cigarettes are obtained either from friends (49.1%) or self purchased (43.6%). Students prefer to smoke at their friend’s house (31.0%) or at school (25.3%). Smoking prevalence among adolescents in Sarawak is high and begins early. Early intervention on smoking prevention and risk awareness is perhaps more effective if initiated before the age of 12 years.
