    Malays J Nutr, 1997;3(2):-.
    MyJurnal
    The objective of this study was to determine the levels of knowledge, attitudes and practices with regards to coronary heart disease (CHD) and its risk factors among CHD patients in the Institut Jantung Negara (National Heart Institute), Kuala Lumpur. All patients admitted for CHD during the study period between 5th May 1997 and 24th May 1997 were included in the study. A total of 105 patients were interviewed by using a pretested questionnaire. Four CHD risk factors were included in the study, namely dietary intake, smoking habit, alcohol intake and physical activity. The majority of the patients (92.4%) were above 45 years old. Most of them (85.7%) had at least one chronic health problem such as diabetes mellitus and hypertension before admission into IJN. Their average total blood cholesterol was 6.1 ± 1.3 mmol/L and 75.2% were hypercholesteromic (≥ 5.2 mmol/L). Mean systolic blood pressure was 151.2 ± 27.5 mmHg. The mean body mass index of the patients was 25.9 ± 3.9 kg/m2 and 58.1% were overweight (BMI ≥ 25.0). Almost half of the patients (49.6%) had smoked before but only 8.6% still smoke. Out of the 56 non-Muslim patients, 9 of them (16.1%) consumed alcoholic drinks on a regular basis. Most of the patients reported walking as the only form of exercise that they do. Most of the patients consume rice, vegetables and fruits almost daily. This study indicated significant relationships between (i) knowledge level and attitude towards CHD risk factors (r = 0.624, p < 0.001), (ii) knowledge level and modifying practices related to CHD risk factors (r = 0.316, p < 0.01) and (iii) attitude and modifying practices (r = 0.234, p

  2. National Health Morbidity Survey II (1996)
    Citation: National Health Morbidity Survey 1996. Kuala Lumpur: Ministry of Health, Malaysia, 1997
    Study name: National Health and Morbidity Survey (NHMS-1996)

    The Second National Health and Morbidity Study (NHMS 2) was conducted in 1996 and funded by R&D Funding under the Intensification of Research in Priority Areas Programme, Government of Malaysia and Ministry of Health. The need for this survey was identified during a discussion on research priority areas for the Seventh Malaysia Plan. NHMS 2 was aimed to provide community based data and information for the MOH to review health priorities, programme strategies and activities and planning for allocation of resources.
    The scopes covered in this survey were load of illness, health seeking behaviour, healthcare consumption cost, health related behaviours (exercise, breast-feeding practices, pap-smear behaviour: smoking alcohol consumption, drug abuse, sexual practices), specific health problems (hypertension, ischaemic heart disease, diabetes mellitus, medically diagnosed cancer, injury, physical impairments, astmna and acute respiratory infections), and blood choleterol level. The NHMS 2 covered whole Malaysia including Sabah and Sarawak. The response rate at Living Quarters (LQ) level was 86.9%.

  3. Anthropometric status and resting metabolic rate in users of the areca nut and smokers of tobacco in rural Sarawak
    Strickland SS, Duffield AE
    Ann Hum Biol, 1997 Sep-Oct;24(5):453-74.
    PMID: 9300122
    The areca nut is chewed by many of the world's population, mainly in South and Southeast Asia. Anthropometric data for 458 Sarawaki adults aged over 24 years, measured both in 1990 and in 1996, were examined in relation to use of tobacco and areca nut. Compared to non-smokers, smoking men were significantly taller and slightly (not significantly) thinner in both years, while smoking women were thinner in 1990 and slightly (not significantly) thinner in 1996. In both sexes there was an increase in the mean and range of body mass index (BMI, W/H2) over the 6-year interval. Smoking women showed a significantly smaller increment in BMI after allowing for areca nut use, which was associated with a similar trend, and this finding depended on including areca use in the model. The trend for men was similar. Possible effects of areca use could reflect variation in 'affluence' or conservatism, or appetite suppression. However, resting metabolic rate in 54 men and 70 women aged 24-60 years was associated with areca use. This association appeared to be mediated by the maximum room temperature of the 24 h preceding measurement. In women, a significant curvilinear association of RMR with maximum temperature was found in users of areca nut but not in non-users. In men, RMR was 7% higher (p < 0.05) in users of areca nut than in non-users, after allowing for age, height, weight, the sum of four skinfold thicknesses, and haemoglobin, but the association with maximum temperature was similar in both groups. It is speculated that constituents of areca nut modulate thermoregulatory pathways, resulting in prolonged temperature-dependent and hyperthermic heat production in this population; that males are more responsive to this effect than females; and that by this mechanism, and possibly also through centrally mediated effects on appetite for food, areca use could contribute to long-term variation in energy balance represented by change in BMI.

  4. Plasma vitamins A, C and E in the general population of Singapore, 1993 to 1995
    Hughes K, New AL, Lee BL, Ong CN
    Ann Acad Med Singap, 1998 Mar;27(2):149-53.
    PMID: 9663300
    The National University of Singapore Heart Study measured cardiovascular risk factors, including selected plasma vitamins, on a random sample of the general population aged 30 to 69 years. Plasma vitamins A and E were normal and similar by ethnic group. Mean plasma vitamin A levels were: Chinese (males 0.68 and females 0.52 mg/L), Malays (males 0.67 and females 0.54 mg/L), and Indians (males 0.66 and females 0.51 mg/L). Mean plasma vitamin E levels were: Chinese (males 12.6 and females 12.6 mg/L), Malays (males 13.6 and females 13.3 mg/L), and Indians (males 12.9 and females 12.8 mg/L). No person had plasma vitamin A deficiency (< 0.01 mg/L) and only 0.1% had vitamin E deficiency (< 5.0 mg/L). In contrast, plasma vitamin C was on the low side and higher in Chinese than Malays and Indians. Mean plasma vitamin C levels were: Chinese (males 6.3 and females 8.4 mg/L), Malays (males 5.1 and females 6.4 mg/L), and Indians (males 5.7 and females 6.9 mg/L). Likewise, the proportions with plasma vitamin C deficiency (< 2.0 mg/L) were lower in Chinese (males 14.4 and females 0.7%), than Malays (males 19.7 and females 7.2%), and Indians (males 17.8 and females 11.0%). Relatively low levels of plasma vitamin C may contribute to the high rates of coronary heart disease and cancer in Singapore. In particular, lower plasma vitamin C in Malays and Indians than Chinese may contribute to their higher rates of coronary heart disease. However, plasma vitamin C does not seem to be involved in the higher rates of cancer in Chinese than Malays and Indians. The findings suggest a relatively low intake of fresh fruits and a higher intake is recommended. Also, food sources of vitamin C may be destroyed by the high cooking temperatures of local cuisines, especially the Malay and Indian ones.

    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.

  7. Fulltext Nutrition and ecosystems in Sarawak: The role of the areca nut
    Strickland SS, Duffield AE
    Asia Pac J Clin Nutr, 1998 Dec;7(3/4):300-6.
    PMID: 24393688
    The effects of population pressure on agricultural sustainability in the delicate tropical and subtropical ecosystems have often been thought to explain high prevalence rates of malnutrition in rural South-East Asia. However, recent studies in rural Sarawak suggest that processes of modernisation have resulted in increased variations in energy nutritional status in adults. A contributory factor may be consumption of the areca nut (Malay pinang, of the palm Areca catechu). This is thought to influence energy balance through effects on appetite and resting metabolic rate. Body mass index (BMI, kg/m2) data for 325 Iban men and 438 non-pregnant Iban women, measured in 1990 and again in 1996, have been analysed in relation to areca use, smoking behaviour, socio-economic status, and reported morbidity. Body composition derived from skinfold thickness measurements for 313 men and 382 women was also analysed. The results suggest that use of areca nut is associated with significantly lower age-related increments in BMI and percentage body fat in women after allowing for age, smoking, reported morbidity, and confounding socio-economic factors. Therefore, the impact of recent economic and social development seen in rising prevalences of 'over-nutrition' may be modulated by use of the areca nut.

  8. Immigrant Health Study. 1. Foreign workers' Health: pilot study sociological aspect. [Abstract]
    Wong YL, Fauza AG
    JUMMEC, 1998;3:60-60.
    The majority of migrant workers studied in this pilot survey were male, from Bangladesh and Muslim. The mean age was 30 years and the majority were aged between 21-30 years. Although almost half of them had 7-13 years of schooling, or an equivalent to secondary education, the majority were work- ing in the Service industry, predominantly in cleaning services. It is noted that this enlployment trend varied from the national situation, whereby majority of legal migrant workers (Indonesian and Thai) are found in the agricultural sector. More than two thirds of the migrant workers were provided with various forms of housing by the employer. However, it is not known if such acconunodation was adequate or not, as there were no questions about housing structures aod extent of overcrowding. Majority of them stated that they had better amenities, such as piped drinking water and sanitaly toilets, here in Malaysia compared to those in their home countries. Yet, the real extent of better sani- tation is difficult to assess since verification of such amenities could not be done. From their self- reports, it appears that the majority did not engage in risk behaviours, such as smoking, alcohol and drug abuse. It is pertinent, however, to include other risk behaviours in the study, particularly the area of sexual behaviour. The pilot study yielded 28 female Indonesian migrant workers. More than two thirds of them were married. Although none of the married women reported that they were pregnant at the time of the survey, more than two thirds of then1 had betweenl-3 children in Malaysia. Since the age range of these children would be an important indicator of the need for preventive health care, it is proposed that age range of the accompanying children and their immunisation status be included in the questionnaire. Just below half of them were currently practising family planning, and more than two thirds were using modern methods, such as, pill, Norplant and IUD. It is recotnmended that in addition to pregnancy and family planning information, the study could also collect data on gynaeco- logical health and the health seeking behaviour for these problems.

  9. Fulltext Peak expiratory flow rate in elderly Malaysians
    Srinivas P, Chia YC, Poi PJH, Ebrahim S
    Med J Malaysia, 1999 Mar;54(1):11-21.
    PMID: 10971999
    An epidemiological survey was conducted among 1,414 healthy ambulatory elderly persons aged 55 years and above in the Kuala Langat district, Selangor. The relationship between peak expiratory flow rate (PEFR), demographic variables, socioeconomic status, smoking, alcohol use and respiratory symptoms were examined. The peak expiratory flow declined with age and were lower in women of all ages. Smoking had a modest effect on PEFR in men but not on PEFR in women. The combination of respiratory symptoms of cough, phlegm and wheeze were related to lower PEFR values. Prediction equations are presented derived from the population sample which may be of assistance in assessing observed to expected ratios among elderly people in Malaysia.

  10. 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.

  11. Fulltext Association between smoking and periodontal disease: a review of the literature
    Ramli J, Taiyeb Ali TB
    Ann Dent, 1999;6(1):21-6.
    MyJurnal
    The role of smoking as a contributory factor in the progression of the periodontal disease process has long been suspected and recently a large number of studies have been published in the dental literature regarding this possible role. Much of the literature has also indicated that smokers affected with periodontitis respond less favorably to periodontal treatment be it non-surgical, surgical and regenerative. This paper will review the current literature regarding the effects of smoking on various aspects of the periodontal disease process and present an explanation for the possible association between smoking and the progression of periodontitis.

    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.

    PMID: 11127329
    A survey was conducted between 1995 and 1997 to assess the impact of introduction of unleaded petrol and other public health measures on the blood lead level of the population. The geometric mean blood lead level of 269 government employees as determined by graphite furnace atomic absorption spectroscopy, was 66.0 microg/l, much lower than that recorded before introduction of lead-free petrol. Using multiple regression analysis, factors significantly associated with blood lead levels were: exposure to traffic, age (>50 years) and active smoking. Passive smoking, exposure to recent paint work, consumption of alcohol and traditional medicine were found not to be significantly associated with the blood lead level.

    JUMMEC, 2000;5:86-88.
    A cross-sectional study on the prevalence of smoking among Form 3, 4 and 5 students of a rural national co-educational school was carried out using a selfadministered questionnaire. By the age of 18 years old, three quarters of boys had tried smoking compared with 12% of girls. About a third of boys were still smokers while only 0.7% of girls were still smokers. There was a higher prevalence of smokers among students who stayed with their parents and those who were working part-time. Most smokers knew about the dangerous and addictive effect of cigarette smoking but smoked because of "influence by school peers", "curiosity" and "to increase concentration and decrease tension".

    The objectives of the Asian Osteoporosis Study (AOS) were to determine risk factors for hip fracture in men and women in four Asian countries, that is, Singapore, Malaysia, Thailand, and the Philippines. A total of 451 men and 725 women (aged 50 years and over) with hip fractures were compared with an equal number of community controls. A standardized questionnaire was administered by interview. The following relative risks (RRs) were found in women and men by multiple logistic regression: dietary calcium intake < 498 mg/day, 2.0 for women (95% CI, 1.5-2.8) and 1.5 for men (95% CI, 1.0-2.2); no load bearing activity in the immediate past, 2.0 for women (95% CI, 1.4-2.7) and 3.4 for men (95% CI, 2.3-5.1); no vigorous sport activities in young adulthood, 7.2 for women (95% CI, 4.0-13.0) and 2.4 for men (95% CI, 1.6-3.6); cigarette smoking, 1.5 for men (95% CI, 1.0-2.1); alcohol consumption 7 days a week, 2.9 for women (95% CI, 1.0-8.6) and 1.9 for men (95% CI, 1.1-3.2); fell twice or more in the last 12 months, 3.0 for women (95% CI, 1.8-4.8) and 3.4 for men (95% CI, 1.8-6.6); a history of fractures after 50 years of age, 1.8 for women (95% CI, 1.1-2.9) and 3.0 for men (95% CI, 1.6-5.6); a history of stroke, 3.8 for women (95% CI, 2.0-7.1) and 3.6 for men (95% CI, 1.8-7.1); use of sedatives, 2.5 for women (95% CI, 1.0-6.3) and 3.0 for men (95% CI, 1.0-9.7); and use of thyroid drugs, 7.1 for women (95% CI, 2.0-25.9) and 11.8 for men (95% CI, 1.3-106.0). Women who were 1.56 m or taller had an RR of 2.0 (95% CI, 1.3-3.0) for hip fracture and men who were 1.69 m or taller had an RR of 1.9 (95% CI, 1.2-3.1) for hip fracture. Based on these findings, primary preventive programs for hip fracture could be planned in Asia.
