Cigarette smoking in adolescent is a significant public health problem, leading to the risk of addiction, morbidity, and mortality in the long term. This study determined the prevalence and correlates of current smoking among adolescent school children. A nationwide school-based survey among 25 507 students between Forms 1 to 5 (aged 12-17) was conducted using a 2-stage cluster sampling design. The prevalence of current smoking was 11.5%. Multivariable logistic regression analysis revealed that current smoking was significantly associated with males (adjusted odds ratio [aOR] = 3.25; 95% confidence interval [CI] = 1.87, 4.98), current drinking (aOR = 2.34; 95% CI = 1.46, 3.74), drug used (aOR = 2.97; 95% CI = 1.24, 7.11), and being bullied (aOR = 1.41; 95% CI = 1.00, 1.98) at least once in the past 12 months. Smoking is associated with several behaviors that pose risks to adolescents, such as social issues and smoking-related health problems. Thus, early and integrated prevention programs that address multiple risk behaviors simultaneously are required.

PMID: 19248698 MyJurnal

A study was undertaken to assess the accuracy of the Omron HEM-907 blood pressure measuring device for use in community studies. A modified version of the British Hypertension Society (BHS) and American Association for the Advancement Medical Instrumentation (AAMI) protocol for measuring the accuracy of a blood pressure measuring device was used. A total of 104 subjects were recruited from two clinics. Observer-observer agreement for readings within the 5 mmHg was good; 80.8% and 84.6% of systolic blood pressure (SBP) and diastolic blood pressure (DBP) agreement respectively. Of the two, the better observer-device agreement readings within the 5 mmHg were 66.4% and 50.0% for SBP and DBP respectively, giving an overall grade B. The mean differences and standard deviation of the differences were within < or =5 mmHg with a standard deviation (SD) of < or =8 mmHg. The Omron HEM-907 satisfied both the AAMI and BHS protocols for accuracy for a non-invasive blood pressure monitoring device using single observer readings.

Int J Tuberc Lung Dis, 2012 Aug;16(8):1126-8.
PMID: 22668450 DOI: 10.5588/ijtld.11.0254

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.

PMID: 18705471

This study was conducted to asses the future physicians' habits, knowledge and attitude towards smoking. These factors influence the credibility of future Malaysian physicians as advocators and treatment providers. A cross sectional study was carried out among medical students at the Medical Faculty, University Malaya. Knowledge on smoking was evaluated on the total scores for knowledge questions, with one point and zero for each correct and incorrect answer respectively, to a maximum of six potential points. Attitude towards smoking was measured by summation of scores on attitude items; each item was scored from five points for "against smoking" and one point for "favourable to smoking". The possible score ranged from 10 to 50. The response rate was 79.4%. Prevalence of overall smokers was 4.4%. The mean knowledge score among smokers (4.30 +/- 2.17) was significantly lower than nonsmokers (5.19 +/- 1.28). The mean attitude score was higher among non-smokers (44.30 +/- 6.54) than smokers (39.86 +/- 10.93). The result from this study showed that smoking prevalence was lower compared to previous studies done in Malaysia.

Tee GH, Gurpreet K, Hairi NN, Zarihah Z, Fadzilah K

Int J Tuberc Lung Dis, 2013 Dec;17(12):1652-5.
PMID: 24200284 DOI: 10.5588/ijtld.12.0241

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.

The World Health Organization (WHO) estimates that injury will be the second leading cause of morbidity of disease burden worldwide by the year 2020. We conducted a community-based survey to determine the prevalence of recent illness and injury, in Malaysia. The survey was a cross sectional population-based household survey conducted using face to face interviews. The information was on self-reported recent illness and injury (SRRII) over the previous 2 weeks. This study was conducted during April - August 2006 and as a part of the third National Health and Morbidity Survey of Malaysia. A total of 56,710 respondents were interviewed with a response rate of 98.2% (55,660/56,710). The overall prevalence of combined SRRII was 23.6%; for injuries the prevalence was 3.1%. The groups with the highest SRRII were children 0-5 years old (31.2%), males (24.3%), Indians (26.9%), those with secondary education level (22.9%), those earning RM 1,000/ month (25.0%) and rural dwellers (25.5%). Age, sex, ethnicity, and locality were significantly associated with SRRII while monthly household income and educational level were marginally associated. On multivariate analysis, age, gender, race, ethnicity, education, income and locality were significantly associated with SRRII. The most common reported recent illness was related to the respiratory system (42.0%). The information obtained from this survey is useful to policy makers in the Ministry of Health to review and strengthen existing health programs.

PMID: 21710867

About 1.8 million people die annually from acute diarrheal disease globally. A nationwide cross-sectional survey was conducted via face-to-face interview with eligible subjects to determine the incidence and health seeking behavior of Malaysians with acute diarrheal disease (ADD). An acute diarrheal episode was defined as having three or more loose stools in any 24 hour period during the four weeks period prior to the interview. The exclusion criteria included pre-existing chronic diarrhea, such as with cancer of the bowel, ulcerative colitis or Chrohn's disease. Forty three point three percent of those with ADD (95% CI 41.3-45.4) sought treatment for the illness. Younger age groups (0-4 years, 67.7%; 95% CI 61.5-73.4; 5-9 years, 56.5%; 95% CI 48.6-64.1) were more likely to seek care for ADD. Seventy-one point eight percent of those seeking treatment, (95% CI 69.0-74.4) did so within 12 hours of the onset of symptoms. Most people with ADD sought treatment at private clinics. The main reasons given for not seeking treatment were the illness was mild and did not warrant treatment and the practice of self-medication (22.4%; 95% CI 20.0-24.9). These findings show self-medication is a major health seeking behavior among Malaysians with ADD. Self-medication of ADD deserves more in-depth study to ensure it is safe.

PMID: 23765141 MyJurnal

The third National Health Morbidity Survey was conducted in 2006 on a nationally representative sample of population in Malaysia in order to obtain community-based data and information on the prevalence of chronic illness. Of 57,500 eligible respondents 56710 (98.6%) participated in the study. Estimated overall prevalence of chronic illness in the Malaysian population within a recall period of one year was 15.5% (95% CI 15.1% - 15.9%). Chronic illness was reported significantly higher among the females, 16.8% (16.3 - 17.3). The most common chronic illness was hypertension (7.9%, 7.6 - 8.2), followed by diabetes mellitus (4.0%, 3.8 - 4.2) and highest reported by the Indians (19.7%, 18.4 - 21.0). Among the respondents who had sought treatment for chronic illness from government health facilities, Malays (65.8%) and those with monthly household income of less than RM400 (76.6%) were the highest. Chinese (44.5%) and those with household income of RM5000 and above (54.3%) were the highest groups who sought treatment from the private health facilities. Most of the respondents reported mild illness was the main reason for not seeking treatment for their chronic illness. It is hoped that the results of this survey will help the Ministry of Health Malaysia to enhance health programmes and planning resource allocation in order to improve health status of the population.

Tee GH, Aris T, Rarick J, Irimie S

Asian Pac J Cancer Prev, 2016;17(3):1269-76.
PMID: 27039759

BACKGROUND: Tobacco consumption continues to be the leading cause of preventable deaths globally. The objective of this study was to examine the associaton of selected socio-demographic variables with current tobacco use in five countries that participated in the Phase II Global Adult Tobacco Survey in 2011 - 2012.
MATERIALS AND METHODS: We analysed internationally comparable representative household survey data from 33,482 respondents aged ≥ 15 years in Indonesia, Malaysia, Romania, Argentina and Nigeria for determinants of tobacco use within each country. Socio-demographic variables analysed included gender, age, residency, education, wealth index and awareness of smoking health consequences. Current tobacco use was defined as smoking or use of smokeless tobacco daily or occasionally.
RESULTS: The overall prevalence of tobacco use varied from 5.5% in Nigeria to 35.7% in Indonesia and was significantly higher among males than females in all five countries. Odds ratios for current tobacco use were significantly higher among males for all countries [with the greatest odds among Indonesian men (OR=67.4, 95% CI: 51.2-88.7)] and among urban dwellers in Romania. The odds of current tobacco use decreased as age increased for all countries except Nigeria where. The reverse was true for Argentina and Nigeria. Significant trends for decreasing tobacco use with increasing educational levels and wealth index were seen in Indonesia, Malaysia and Romania. Significant negative associations between current tobacco use and awareness of adverse health consequences of smoking were found in all countries except Argentina.
CONCLUSIONS: Males and the socially and economically disadvantaged populations are at the greatest risk of tobacco use. Tobacco control interventions maybe tailored to this segment of population and incorporate educational interventions to increase knowledge of adverse health consequences of smoking.

Acute diarrhoea is a major health problem in many parts of the world, contributing to about 1.8 million deaths globally. The objectives of the study were to assess the incidence, determinants, and severity of acute diarrhoea in the population. A nation-wide cross-sectional survey involving about 57,000 respondents was conducted via face-to-face interview among eligible respondents of all ages. An acute diarrhoeal episode was defined as having three or more episodes of loose stools in any 24-hour period within the past four weeks before the interview. The severity was measured by duration of acute diarrhoea and associated symptoms. The variables tested as determinants were age, sex, ethnicity, the highest educational level, total monthly household income, and locality. Univariate, bivariate and multivariate procedures meant for complex study design were used in the analyses. The four-week incidence of acute diarrhoea was 5% [95% confidence interval (CI) 4.8-5.2]. The incidence of acute diarrhoea among the estimated population was the highest among young adults aged 20-29 years, Other Bumiputras (the pre-dominant ethnic group in East Malaysia), those with tertiary-level of education, those earning a monthly household income of less than RM 400, and rural dwellers. Only age, ethnicity, the highest level of education attained, and locality were significantly associated with acute diarrhoea in bivariate analysis. In multivariate analysis, these four variables were found to be the determinants of acute diarrhoea. Sex and monthly household income were excluded from the model. The mean duration of acute diarrhoea was 2.0 days (standard deviation 1.3). Forty-six percent of the respondents reported stomach cramps as an associated symptom. The findings revealed that acute diarrhoea is still a major public-health concern in Malaysia and grossly under-notified. There is a need for intensification of public-health intervention efforts to reduce the incidence of acute diarrhoea while improving surveillance and notification of the disease.

The Malaysian National Health Morbidity Survey III (NHMS III), conducted in 2006, was a cross-sectional household survey of the prevalence of chronic diseases, involving 34,539 respondents of age > or =18 years old, in all states of Malaysia. Data collection was by face-to-face interview. Those who self-professed not to be diabetics underwent finger-prick glucose test following at least 8 hours of fasting. The overall prevalence of diabetes mellitus (known and newly diagnosed) was 11.6%. The Indians had the highest prevalence of 19.9% followed by Malays 11.9% and Chinese 11.4%. The prevalence of people with known diabetes and newly diagnosed diabetes was 7.0% and 4.5% respectively. Impaired Fasting Glycaemia was found to be 4.2%. Majority (73.5%) of the patients used government healthcare facilities for their diabetic care. Usage of insulin alone or in combination was low at 7.2% of patients. Only 45.05% of known diabetics have ever had their eye examined. Amputees formed 4.3% of the patients with known diabetes while 3.4% had suffered a stroke event and 1.6% was on some form of renal replacement therapy.

Fulltext Systematic review on international practices in controlling waterpipe tobacco smoking

Tee GH, Hairi NN, Nordin F, Choo WY, Chan YY, Kaur G, et al.

Asian Pac J Cancer Prev, 2015;16(9):3659-65.
PMID: 25987018

BACKGROUND: Waterpipe tobacco smoking has becoming popular especially among young people worldwide. Smokers are attracted by its sweeter, smoother smoke, social ambience and the misconception of reduced harm. The objective of this study was to systematically review the effects of waterpipe tobacco policies and practices in reducing its prevalence.

MATERIALS AND METHODS: A systematic review was conducted electronically using the PubMed, OVID, Science Direct, Proquest and Embase databases. All possible studies from 1980 to 2013 were initially screened based on titles and abstracts. The selected articles were subjected to data extraction and quality rating.

RESULTS: Three studies met the inclusion criteria and were eligible for this review. Almost all of the waterpipe tobacco products and its accessories did not comply with the regulations on health warning labelling practices as stipulated under Article 11 of WHO FCTC. In addition, the grisly new warning labels for cigarettes introduced by Food and Drug Administration did not affect hookah tobacco smoking generally. Indoor air quality in smoking lounges was found to be poor and some hookah lounges were operated without smoke shop certification.

CONCLUSIONS: Our findings revealed the availability of minimal information on the practices in controlling waterpipe smoking in reducing its prevalence. The lack of comprehensive legislations or practices in controlling waterpipe smoking warrants further research and policy initiatives to curb this burgeoning global epidemic, especially among the vulnerable younger population.

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.

Fulltext Effectiveness of training stop-smoking advisers to deliver cessation support to the UK national proposed standard versus usual care in Malaysia: a two-arm cluster-randomized controlled trial

Wee LH, West R, Tee GH, Yeap L, Chan CMH, Ho BK, et al.

Addiction, 2021 08;116(8):2150-2161.
PMID: 33220115 DOI: 10.1111/add.15346

AIMS: To assess the effectiveness of training stop smoking services providers in Malaysia to deliver support for smoking cessation based on the UK National Centre for Smoking Cessation and Training (NCSCT) standard treatment programme compared with usual care.
DESIGN: Two-arm cluster-randomized controlled effectiveness trial across 19 sites with follow-up at 4-week, 3-month, and 6-month.
SETTING: Stop smoking services operating in public hospitals in Malaysia.
PARTICIPANTS: Five hundred and two smokers [mean ± standard deviation (SD), age 45.6 (13.4) years; 97.4% male] attending stop smoking services in hospital settings in Malaysia: 330 in 10 hospitals in the intervention condition and 172 in nine hospitals in the control condition.
INTERVENTION AND COMPARATOR: The intervention consisted of training stop-smoking practitioners to deliver support and follow-up according to the NCSCT Standard Treatment Programme. The comparator was usual care (brief support and follow-up).
MEASUREMENTS: The primary outcome was continuous tobacco smoking abstinence up to 6 months in smokers who received smoking cessation treatment, verified by expired-air carbon monoxide (CO) concentration. Secondary outcomes were continuous CO-verified tobacco smoking abstinence up to 4 weeks and 3 months.
RESULTS: Follow-up rates at 4 weeks, 3 months and 6 months were 80.0, 70.6 and 53.3%, respectively, in the intervention group and 48.8, 30.8 and 23.3%, respectively, in the control group. At 6-month follow-up, 93 participants in the intervention group and 19 participants in the control group were abstinent from smoking, representing 28.2 versus 11.0% in an intention-to-treat (ITT) analysis assuming that participants with missing data had resumed smoking, and 52.8 versus 47.5% in a follow-up-only (FUO) analysis. Unadjusted odds ratios (accounting for clustering) were 5.04, (95% confidence interval (CI) = 1.22-20.77, P = 0.025) and 1.70, (95% CI = 0.25-11.53, P = 0.589) in the ITT and FUO analyses, respectively. Abstinence rates at 4 week and 3 month follow-ups were significantly higher in the intervention versus control group in the ITT but not the FUO analysis.
CONCLUSIONS: On an intention-to-treat analysis with missing-equals-smoking imputation, training Malaysian stop smoking service providers in the UK National Centre for Smoking Cessation and Training standard treatment programme appeared to increase 6 month continuous abstinence rates in smokers seeking help with stopping compared with usual care. However, the effect may have been due to increasing follow-up rates.
Fulltext Prevalence and characteristics of e-cigarette users among Malaysian current and ex-smokers

Introduction: Electronic cigarettes (ECs) are new devices that have been accepted widely by both smokers and non-smokers. However, the evidence on EC used in Malaysia is scarce. The objective of this study was to determine the prevalence of EC use and the socio-demographic and smoking characteristics associated with current EC use among Malaysian current and ex-smokers.

Methods: This was a sub-analysis of data from a cross-sectional, national-population- based EC study conducted from May to June in 2016 in Malaysia. A detailed description of the sampling methods can be found in the National E-cigarette Survey (NECS) 2016 report. Briefly, data were obtained from 1396 individuals who had ever been smokers, i.e., 957 (68.6%) current smokers and 439 (31.4%) ex-smokers.

Results: Current EC use was found predominantly among current smokers (8.0%) as compared with ex-smokers (4.3%). Among current smokers, the main reasons given for smoking ECs were wanting to try it (44.7%), followed by intention to quit tobacco smoking (15.8%) and to reduce tobacco smoking (10.5%). Using multiple logistic regression analysis, we found that among current smokers, current EC users were more likely to be younger, i.e., 18-44 years (aOR= 4.83, 95% CI= 1.97-11.86, p=0.001), urban residents (aOR= 1.89, 95% CI= 1.15-3.11, p=0.012), single/ divorced/ widowed (aOR= 2.11, 95% CI= 1.24-3.61, p=0.006) and students (aOR= 2.25, 95% CI= 1.01-5.01, p=0.048). Among exsmokers, only younger respondents (18-44 years old) was reported as being more likely to be current EC users (aOR= 3.81, 95% CI= 1.14-12.76, p=0.030).

Conclusion: This study showed that currently using and ever having used ECs were more prevalent among current smokers. The reasons given for initiating EC use among current smokers were mainly wanting to try it, followed by intention to quit and to reduce tobacco smoking. Current EC use appears to be common among current smokers who are younger, urban residents, single/divorced/widowed and students. Therefore, EC cessation intervention strategies and policies should target these high-prevalence groups.

Electronic cigarettes (e-cigarettes) are a new method for the consumption of nicotine. A nationwide survey among 4288 Malaysian adults was conducted in 2016 to measure the prevalence and to describe the population characteristics of e-cigarette users. A complex sampling design was used, and data were collected using a face-to-face questionnaire. The overall prevalence of current, ever, former, and dual users of e-cigarettes in Malaysia were 3.2% (95% confidence interval [CI] = 2.5-4.1), 11.9% (95% CI = 10.5-13.5), 8.6% (95% CI = 7.5-9.8), and 2.3% (95% CI = 1.8-3.1), respectively. The prevalence of all type of e-cigarette use was higher in urban than in rural areas. Current e-cigarette users were likely to be younger, males, and with higher education level. Among current e-cigarette users, 74% (95% CI = 64-82) also smoked conventional cigarettes (dual user). E-cigarette use is prevalent in Malaysia. It is common among younger adults, males, and cigarette smokers.

BACKGROUND: Typhoid fever causes global morbidity and mortality and is a significant health burden, particularly in low- and middle-income countries. The direct fecal-oral route is the main transmission mode, but indirect environmental transmission could occur, particularly in urban settings. This study aimed to investigate the burden and trend of typhoid fever, reporting the coverage system between government and private practice and pattern of multidrug-resistant (MDR) typhoid cases in the urban Klang Valley area from 2011 to 2015.
METHODS: The data from a cross-sectional study retrieved from the e-Notifikasi System, a national reporting system for communicable diseases provided by the Disease Control Division, Ministry of Health Malaysia and secondary data of all the typhoid cases were obtained from the public and private hospitals and laboratories in Klang Valley. Descriptive analysis was performed to examine the sociodemographic characteristics, spatial mapping was conducted to examine trends, and the crude incidence rates of confirmed typhoid cases and percentage of reporting coverage were calculated. Significant differences between MDR and non-MDR Salmonella typhi were determined in the patient's sociodemographic characteristics, which were analyzed using χ2 test. P values

Smoking is a learned behavior during adolescence, and it is found predominantly among male adolescents in Malaysia. Our study aimed to investigate the prevalence and predictive factors of current cigarette smoking among school-going male adolescents in Malaysia. Data were derived from the National Health and Morbidity Survey: Adolescent Health Survey 2017, a cross-sectional study that utilized a 2-stage stratified cluster sampling to select a nationally representative sample of school-going adolescents in Malaysia (n = 27 497). Multiple logistic regression analysis was performed to identify factors associated with current cigarette smoking among male adolescents in Malaysia. Male adolescents aged 16 to 17 years (adjusted odds ratio [AOR] = 1.55; 95% confidence interval [CI] = 1.41-1.70), current illicit drug users (AOR = 8.14; 95% CI = 6.37-10.41), current alcohol users (AOR = 1.92; 95% CI = 1.65-2.23), those from rural schools (AOR = 1.60; 95% CI = 1.46-1.76), those whose parents were widowed/divorced/separated (AOR = 1.37; 95% CI = 1.21-1.55), and those whose parents/guardians were tobacco product users (AOR = 3.47; 95% CI = 2.33-5.16) were more likely to be current cigarette smokers. Tobacco control strategies should be aimed at both adolescents at risk and at promoting parental smoking cessation.

Little is known about the perceptions of harm and benefit associated with the use of e-cigarettes in Malaysia. This was a cross-sectional analysis of a nationally representative sample comprising 1987 males (≥18 years of age). Current, former, and never users of conventional cigarettes and/or e-cigarettes participated in a questionnaire study conducted via face-to-face interviews. The relationship between participant characteristics and perceptions of harm and benefit of e-cigarettes were determined with multivariable logistic regression. There were 950 current, 377 former, and 660 never users of e-cigarettes. Government employees (odds ratio [OR] = 1.85, 95% confidence interval [CI] = 1.29-2.66, P = .001), private sector employees (OR = 1.67, 95% CI = 1.27-2.18, P = .001), and the self-employed people (OR = 1.68, 95% CI = 1.31-2.17, P = .001) were more likely to perceive e-cigarettes as more harmful than conventional cigarettes compared with respondents who were not wage earners. All current users in the form of e-cigarette users (OR = 7.87, 95% CI = 3.23-19.18), conventional cigarette smokers (OR = 1.80, 95% CI = 1.39-2.33), and dual users (OR = 8.59, 95% CI = 4.76-15.52) were more likely to perceive e-cigarettes as useful in quitting conventional cigarette smoking compared with former and never users. Our findings constitute an important snapshot into the perceptions of e-cigarette harms and benefits, which could inform targeted public health messaging strategies.
