    Pathmanathan I
    Med J Malaysia, 1975 Dec;30(2):88-92.
    PMID: 1228387
    In a study during 1972 of smoking habits of Malaysian medical students, smoking rates of medical students was seen to be higher than that of students in four other faculties in the University of Malaya. Male Malaysian medical students had higher smoking rates than their counterparts in Glasgow in 1971 (UM 20.3%, Glasgow 19.1%) but Malaysian females had very low smoking rates (male 25.2%, female 1.6%). Despite the fact that in the medical curriculum students are made aware of the scientific evidence on the health hazards of smoking, smoking rates were higher in students int their later years of study. Ethnicity was associate with smoking rates although father's smoking habit was not - and Malays had the highest smoking rates (malay 28.2%, chinese 16.3%, indian and others 23.5%).

    PMID: 2595383
    Coronary heart disease which was responsible for 2.9% of all deaths 30 years ago, today accounts for 19% of deaths. The rising trend which declined in 1985, appears to be stabilising now. Indians have mortality rates which are 3 times that of Chinese. This is the background against which the Singapore Myocardial Infarction Register was set up in 1967 to provide incidence and prevalence data for coronary heart disease in the country. in 1987 to provide incidence and prevalence data for coronary heart disease in the country.

    Zain RB, Razak IA
    Community Dent Oral Epidemiol, 1989 Jun;17(3):148-9.
    PMID: 2786793
    The association between cigarette smoking and the prevalence of oral mucosal lesions was examined in 495 Malaysian army personnel. No associations between cigarette smoking and recurrent aphthous ulcerations, pre-leukoplakia and frictional keratosis could be obtained in this study. Positive associations were found between cigarette smoking and leukoedema as well as denture stomatitis. There was a negative association between cigarette smoking and the presence of coated tongue.

    Axéll T, Zain RB, Siwamogstham P, Tantiniran D, Thampipit J
    Community Dent Oral Epidemiol, 1990 Apr;18(2):95-9.
    PMID: 2335069
    At the Faculties of Dentistry in Chiang Mai, Thailand (CM), and Kuala Lumpur, Malaysia (KL), 234 and 233 consecutive out-patients of mean ages 33.8 and 31.0 yr, respectively, were examined for the presence of oral mucosal lesions. Tobacco in some form was regularly used by 31.7% and 27.5% of the study populations in CM and KL, respectively. Cigarette smoking was the predominant habit. In CM three persons chewed betel quids and nine smoked banana leaf cigars daily. In addition, there were 24 habitual chewers of tea leaves (miang). In KL six persons chewed betel quids daily. In CM and KL three cases each (1.3%) of tobacco-associated leukoplakias were found. In KL an additional idiopathic leukoplakia was registered. One and three cases of betel related lesions were found in CM and KL, respectively. One case of a squamous cell carcinoma was found in a 45-yr-old Indian woman in KL who had been chewing betel with tobacco daily for many years. High prevalence figures were found for lichen planus, 3.8% in CM and 2.1% in KL, and an extremely high one, 48.3%, in CM for episodes of aphthous ulcers experienced during the last 2 yr. Comparatively low prevalence figures were found for herpes labialis. As could be expected melanin pigmentation was prevalent while only low figures were encountered for denture-related lesions and amalgam tattoos.

  6. Fulltext Cigarette smoking among school children in Singapore. Part I--Smoking prevalence
    Emmanuel SC, Ho CK, Chen AJ
    Singapore Med J, 1990 Jun;31(3):211-6.
    PMID: 2392697
    A cross sectional nationally representative survey of 33,110 school-going children in Singapore aged between 9 and 20 years was carried out to obtain, for the first time, baseline information on smoking among the school-going population in Singapore. The survey was carried out among students attending vocational institutes and public sector schools in Singapore in 1987. The overall smoking prevalence was found to be 2% (3% among boys and 0.2% among girls). Ex-smokers comprised 2% of respondents whilst those who had only experimented with smoking made up 9% of the respondents. Analyses of the data showed that cigarette smoking was more prevalent among Malays, among boys, among older children, and among the less academically inclined. On average, boys smoked a median of 20 cigarettes a week and girls, 12 cigarettes a week. On an international basis, the smoking prevalence among the school-going population in Singapore is significantly lower than that of developed countries like Australia, England and Wales and neighbouring countries such as Malaysia.

    Yaacob I, Ahmad Z, Harun Z
    Med J Malaysia, 1990 Sep;45(3):220-4.
    PMID: 1966930
    A review of 119 patients (88 males and 31 females) with carcinoma of the lung seen at the Hospital University Sains Malaysia (HUSM) from 1984 to 1989 was done. The mean age of the patients was 60.3 years with a high proportion (76.6%) of them were between 41 and 70 years. Seventy five percent of patients (84% of men and 26% of women) were smokers. The Chinese have a significantly higher preponderance to carcinoma of the lung. The commonest histological type found was squamous cell carcinoma in men and adenocarcinoma in women. Small cell carcinoma was uncommon. Squamous cell and large cell/undifferentiated type of carcinoma were significantly associated with smoking behaviour of the patients.

  8. Adjunctive drug use among opiate addicts
    Navaratnam V, Foong K
    Curr Med Res Opin, 1990;11(10):611-9.
    PMID: 2311417
    In a study of 249 opiate (mainly heroin) addicts special attention was paid to adjunctive drug use. Generally, nicotine (cigarette smoking), alcohol and cannabis preceded the use of heroin, and continued to be used as adjunctive drugs after the establishment of heroin addiction. Nicotine was the most common substance used together with opiates. Alcohol and cannabis were used as adjunctive drugs in about two-thirds of the cases. In the late stages of heroin addiction, benzodiazepines were also used concomitantly with opiates. The most frequently reported reason for the use of adjunctive drugs was to intensify the effect of the opiate. Three-quarters or more of the addicts had used different adjunctive drugs to boost the euphoric feeling derived from the primary drug, i.e. heroin. Attempt at self-treatment of withdrawal symptoms was a less frequently reported reason for adjunctive drug use. The findings show that heroin addiction is the major problem. The use of adjunctive drugs, especially benzodiazepines, can be partly explained on economic grounds. They must be clearly distinguished from the primary drug of abuse, heroin. For policy-making decisions, it is important that the elimination of heroin abuse through effective prevention measures would ultimately wipe out the problem of adjunctive drug use, while reduction of the overall supply of heroin without reduction in actual demand might result in an increasing trend to adjunctive drug use.

    Yaacob I, Harun MH
    Southeast Asian J. Trop. Med. Public Health, 1994 Mar;25(1):74-9.
    PMID: 7825029
    A questionnaire survey to study the smoking habits and attitudes toward smoking among secondary school teachers in Kelantan, Malaysia was conducted between July and September 1992. Questionnaires were sent to 5,112 teachers through their respective headmasters. Sixty-three percent (3,208 teachers; 61% males, 39% females) responded satisfactorily. Overall, 625 teachers (20%) were current smokers, 141 (4%) were occasional smokers, 317 (10%) were ex-smokers and 2,123 (67%) had never smoked. Only six (0.8%) of the 766 regular and occasional smokers were females. The rates of smoking among parents and siblings of smokers were higher than parents and siblings of non-smokers. Seventy-four percent of the smoking teachers admitted to smoking in the school premises. The teachers' attitudes about the health effects of smoking were statistically different between smokers and non-smokers. However, both smoking and non-smoking teachers had similar views regarding methods to control the smoking habit which included banning cigarette sales, putting a halt to the tobacco industry and banning cigarette advertisements.

  10. Fulltext Prevalence of asthma and risk factors among Chinese, Malay, and Indian adults in Singapore
    Ng TP, Hui KP, Tan WC
    Thorax, 1994 Apr;49(4):347-51.
    PMID: 8202905
    BACKGROUND: The prevalence and morbidity of asthma vary greatly among different ethnic communities and geographical locations, but the roles of environmental and genetic factors are not fully understood. The differences in prevalence of adult asthma among Chinese, Malay, and Indian ethnic groups in Singapore were examined, and the extent to which these could be explained by personal and environmental factors were investigated.
    METHODS: A stratified disproportionate random sample (n = 2868) of Chinese (n = 1018), Malays (n = 967), and Indians (n = 883) of both sexes was drawn from households in five public housing estates, and an interviewer administered questionnaire was used to determine cumulative and current prevalence of "physician diagnosed asthma" (symptoms with a physician diagnosis of asthma).
    RESULTS: Lifetime cumulative prevalence (standardised to the general population) of "physician diagnosed asthma" was 4.7% in men and 4.3% in women; 12 month period prevalences were 2.4% and 2.0%, respectively. Cumulative prevalence of asthma was significantly higher in Indians (6.6%) and Malays (6.0%) than in Chinese (3.0%); period prevalences of asthma were 4.5% in Indians, 3.3% in Malays, and 0.9% in Chinese. Ownership of cats or dogs was more frequent in Malays (15.4%) and Indians (11.2%) than in Chinese (8.8%). Rugs and carpets were also more frequently used by Malays (52.2%) and Indians (40.7%) than by Chinese (8.9%). Current smoking prevalences were higher in Malays (27.3%) than in Indians (19.4%) and Chinese (23.0%). Malays and Indians did not have higher rates of atopy (11.1% and 15.2%, respectively) than Chinese (15.4%). Adjustment for these factors in multivariate analyses reduced the greater odds of asthma in Malays and Indians, but not to a significant extent.
    CONCLUSIONS: There are ethnic differences in the prevalence of asthma in Singapore which are not entirely explained by differences in smoking, atopy, or other risk factors. Other unmeasured environmental factors or genetic influences are likely to account for residual differences in the prevalence of asthma.

  11. Fulltext Smoking among university students: a comparative study between Malaysian students in Malaysia and Australia
    Hashami B, Abdul Halim O, Yusoff K
    Med J Malaysia, 1994 Jun;49(2):149-57.
    PMID: 8090094
    A total of 209 randomly selected Malaysian university students (128 from Universiti Kebangsaan Malaysia, 81 from the University of New South Wales) completed a self-filled questionnaire enquiring about their smoking behaviour and psychosocial characteristics. The prevalence of smoking was 26.6 per cent among students in Malaysia and 18.8 per cent among students in Australia (average 23.4%). Both samples have similar patterns in terms of age of starting smoking, time of the day when they smoked, family and peer history of smoking, and whether or not they inhaled deeply during smoking. The smokers tend to be male, studying beyond the first year, staying with peers outside the hostel, having financial sources other than a scholarship, and abnormal mental health score. However, the smokers from the Australian samples were noted to smoke less and made fewer attempts at quitting the habit.

  12. Smoking behavior, knowledge and opinion of medical students
    Yaacob I, Abdullah ZA
    Asia Pac J Public Health, 1994;7(2):88-91.
    PMID: 7946655 DOI: 10.1177/101053959400700202
    A questionnaire survey on smoking was conducted among 395 medical students (40% males, 60% females) at the School of Medical Sciences, University Sains Malaysia at Kubang Kerian, Kelantan. Thirty-five students (9%), all of them males, were current smokers. Twenty-eight percent of the smokers smoked more than ten cigarettes per day and 88% began smoking before entering the medical school. Social influence and cigarette advertisements were the main reasons given for starting smoking. Both smokers and nonsmokers were adequately informed of the common adverse effects of smoking. Ninety percent of smokers had tried to give up smoking but failed. Among the ex-smokers and nonsmokers, the main reasons given for not smoking was that smoking was useless. Among the female students, one-third felt that cigarette smoking was socially unacceptable among females. This was one of the three main reasons for not smoking. Very few of the students (4.6%) considered that doctors' advice would play an important role in smoking prevention.

    Noorhassim I, Rampal KG
    Am J Otolaryngol, 1998 8 6;19(4):240-3.
    PMID: 9692632
    PURPOSE: To determine the combined effect of smoking and age on hearing impairment.

    MATERIALS AND METHODS: Pure tone audiometry test was conducted on 263 residents of a rural village who were not exposed to noise. The pack-years of smoking were computed from the subjects' smoking history. The association between pack-years and hearing impairment was assessed. The combined effect of smoking and age on hearing impairment was determined based on prevalence rate ratio.

    RESULTS: There was a statistically significant trend in the number of pack-years of smoking and age as risk factors for hearing impairment. The prevalence rates of hearing impairment for nonsmokers aged 40 years and younger, smokers aged 40 years and younger, nonsmokers older than 40 years of age, and smokers older than 40 years of age were 6.9%, 11.9%, 29.7%, and 51.3%, respectively. The prevalence rate ratio for nonsmokers aged 40 years and younger, smokers aged 40 years and younger, nonsmokers older than 40 years of age, and smokers older than 40 years of age (nonsmokers aged 40 years and younger as a reference group) was 1, 1.7, 4.3, and 7.5, respectively. The prevalence rate ratios showed a multiplicative effect of smoking and age on hearing impairment.

    CONCLUSION: Age and smoking are risk factors for hearing impairment. It is clear that smoking and age have multiplicative adverse effects on hearing impairment.

    Southeast Asian J. Trop. Med. Public Health, 1998 Sep;29(3):643-8.
    PMID: 10437972
    As part of a larger study to bring attention to smoking and smokeless tobacco use among the indigenous people of Sabah State in Malaysia, the Bajaus were interviewed in a cross-sectional survey. 74.4% of the men smoked compared to 3.3% of the women and 77% of women used smokeless tobacco compared to 4.3% of men. Local handrolled cigarettes called kirais were popular and smokeless tobacco was used as an ingredient in the ritual of betel-quid chewing. Tobacco was also used because it was thought to have medicinal effects. The prevalence of smokeless tobacco use was significantly lower among the better educated women but for smoking, education had no relation with prevalence. Both habits could be easily maintained as they were cheap practices which were socially and culturally accepted. Awareness of the adverse effects of such tobacco habits was poor and intervention programs to curb tobacco use is required.

  15. Risk factors for early death in acute ischemic stroke and intracerebral hemorrhage: A prospective hospital-based study in Asia. Asian Acute Stroke Advisory Panel
    Wong KS
    Stroke, 1999 Nov;30(11):2326-30.
    PMID: 10548666
    BACKGROUND AND PURPOSE: In Asia, there has been no international study to investigate the risk factors for early death in patients with ischemic stroke and intracerebral hemorrhage.

    METHODS: We conducted a prospective study of consecutive patients with acute stroke who were admitted to 36 participating hospitals in China, India, Indonesia, Korea, Malaysia, the Philippines, Singapore, Taiwan, Thailand, and Vietnam. With the use of a simple identical data sheet, we recorded the demographics and cardiovascular risk factors of each patient. Early death was defined as death on discharge from the acute hospital.

    RESULTS: We enrolled 2403 patients with ischemic stroke and 783 patients with intracerebral hemorrhage. Among patients with ischemic stroke, previous use of antiplatelet drugs (adjusted odds ratio [OR] 0.53; 95% confidence interval [CI] 0. 30 to 0.95) and relatively young age group 56 to 75 years (OR 0.65; 95% CI 0.42 to 1.00) were protective factors; atrial fibrillation (OR 2.23; 95% CI 1.40 to 3.57), ischemic heart disease (OR 2.03; 95% CI 1.37 to 3.05), diabetes (OR 1.52; 95% CI 1.04 to 2.22), and ex-smoker status (OR 2.18; 95% CI 1.18 to 4.05) were risk factors for early death. Among patients with intracerebral hemorrhage, hypertension (OR 0.56; 95% CI 0.38 to 0.82) and young age group 56 to 75 years old (OR 0.55; 95% CI 0.34 to 0.87) were associated with lower death rate, whereas diabetes (OR 1.74; 95% CI 1.01 to 2.98) was a risk factor for early death.

    CONCLUSIONS: In Asian patients with stroke, previous use of antiplatelet drugs nearly halved the risk of early death in patients with ischemic stroke, whereas atrial fibrillation, ischemic heart disease, diabetes, and ex-smoker status were risk factors for early death. Among patients with intracerebral hemorrhage, diabetes was associated with early death, whereas young age group and hypertension were associated with lower death rates, though no clear explanation for the hypertension association could be discerned from the data available.

  16. Fulltext Family influence on current smoking habits among secondary school children in Kota Bharu, Kelantan
    Shamsuddin K, Haris MA
    Singapore Med J, 2000 Apr;41(4):167-71.
    PMID: 11063181
    Objectives: To measure the prevalence of cigarette smoking among male secondary school children and assess their family influence especially that of their fathers' smoking habits on their current smoking habits.
    Methodology: A cross-sectional study was carried out in Kota Bharu, Kelantan in April 1997 where 460 male form four students, aged 15-16 years were randomly selected from six secondary schools. Data on smoking habits, sociodemographic profile and family characteristics particularly parents and siblings' smoking habits, perceived parental supervision and communication were collected through self-administered questionnaires.
    Results: The prevalence of cigarette smoking among male secondary school children was 33.2%. Crude analysis shows family factors, fathers' and siblings' smoking habits, and lack of parental supervision were significantly associated with the students' current smoking habit. Among students who smoked compared to non-smokers, father's smoking habit gives a crude Odds Ratio = 1.8, 95% C.I. 1.08 - 3.16. Further analysis shows that the effect of their father's smoking habit on the student's current smoking habit is still significant after controlling for other familial and non-familial factors including parental supervision, academic performance, reported influence of cigarette advertisement, having friends who smoked and the student's poor knowledge of the ill-effects of smoking and other factors (Odds Ratio = 1.9, 95% C.I 1.05 - 3.32). In conclusion, family factors especially the father's smoking habit is an important factor that influences a student's current smoking habit and the presence of negative role models within the home need to be seriously considered in any cigarette smoking prevention programs among secondary school adolescents.

  17. Fulltext Factors related to smoking habits of male secondary school teachers
    Naing NN, Ahmad Z
    Southeast Asian J. Trop. Med. Public Health, 2001 Jun;32(2):434-9.
    PMID: 11556602
    A cross-sectional study was conducted to identify the factors related to smoking habits of secondary school teachers in Kelantan, Malaysia. A total of 180 male teachers and trainee teachers from four secondary schools in Kelantan and a Teachers' Training College were interviewed by using a structured questionnaire. Cluster sampling was applied. The significant findings found were current smokers were found as high as 40.56%. Mean duration of smoking was 6.8 years and mean initiation age was 16.5 years. Trainee teachers had a significantly higher proportion of current smokers. There was a significant association between smoking status of teachers and their fathers' and perception of the hazards of smoking on health. Peer influence was found to be the major reason for smoking among smokers. Religious belief and care for health attitude prevented non-smokers from smoking. About 3/5 of smokers thought of quitting smoking and of these 1/4 had tried at least once. There was a significant difference of proportion of attempted quitting between regular and occasional smokers. Mass media was the best source of information on knowledge about smoking hazards. Anti-smoking campaigns should start as early as possible in schools. Lectures and talks on smoking should be included in the curriculum of teachers' training courses.

    Rampal L, Narasimman S
    Med J Malaysia, 2003 Mar;58(1):54-61.
    PMID: 14556326 MyJurnal
    Objectives: i) To determine the prevalence of smoking among the community aged 15 and above in Kg. Jenderam Hilir in Sepang District, Selangor state. ii) To determine the relationship between smoking and age, sex, household income and education. iii) To determine the parental and peer influence on smoking in Kg Jenderam Hilir.
    Materials and Methods: A study was conducted to Kg Jenderam Hilir, Sepang. All residents aged 15 years and above from all the 381 households of Kg Jenderam Hilir were included in this study. A standardized pre-tested structured questionnaire was used in this study.
    Results: Out of 894 respondents interviewed 69% were males compared to 3.9% of the females (overall 33.6%) reported to have smoked at least once in his/her lifetime. The difference was statistically significant. The mean duration of smoking was 17.7 years. The age at which smoking was first attempted ranged from 4 years to 51 years with a mean of 18.7 years. The mean initiation age for the males was significantly lower as compared to the mean initiation age for the females. The prevalence of current smokers was significantly higher amongst males (52.8%) as compared to the females (1.4%). The prevalence of smoking among current smokers increased with age (p<0.01). there was no significant difference in the prevalence of smoking by household income and educational level. The mean number of cigarettes smoked by current smokers per day was 14.9 cigarettes and ranged from 1 to 60 cigarettes. The mean number of cigarettes smoked by the males was significantly higher than the females (p<0.05). the mean duration of smoking among current smokers was 20 years. There was a significant difference in the level of addiction to smoking and the duration of smoking (p<0.05). sixty five percent of the current smokers reported to have tried to quit smoking while 26% of ever smokers had reported to quit smoking and remained non-smokers. The quit ratio was calculated to be 26.0%. the quit ratio was 52.6% among those with college or university education. There was a significant difference in the quit ratio by education level (p<0.01). There was no significant difference in smokers whose parents were smokers as compared to non-smokers whose parents were smokers. However, there was a significant association between smoking and peer influence (p<0.01).
