- PublicationAssociation between Availability of Neighborhood Fast Food Outlets and Overweight Among 5–18 Year-Old Children in Peninsular Malaysia: A Cross-Sectional Study(2019)
;Kee Chee Cheong ;Cheong Yoon Ling ;Lim Kuang Hock ;Sumarni Mohd Ghazali ;Teh Chien Huey ;Mohd Che Ibrahim ;Azli Baharudin ;Cheong Siew Man ;Cheah Yong Kang ;Noor AhmadAhmad YusoffA growing number of fast-food outlets in close proximity to residential areas raises a question as to its impact on childhood overweight and obesity. This study aimed at determining the relationship between the availability of fast-food outlets that were in close proximity to residential areas and overweight among Malaysian children aged 5 to 18 years. Measurement data on the weight and height of 5544 children (2797 boys, 2747 girls) were obtained from the National Health and Morbidity Survey 2011. Overweight (including obesity) is defined as BMI-for-age z-score > +1 SD based on the WHO growth reference. Geographic information system geospatial analysis was performed to determine the number of fast-food outlets within 1000 m radius from the children’s residential address. Multiple logistic regression was conducted to examine the association between the availability of fast-food outlets (none or more than one outlet) and overweight with adjustment for age, sex, ethnicity, monthly household income, parental educational level, residential area and supermarket density. Our results showed that the prevalence of overweight was 25.0% and there was a statistically significant association between the density of fast-food outlets and overweight (odds ratio: 1.23, 95% confidence interval: 1.03, 1.47). Our study suggested that the availability of fast-food outlets with close proximity in residential areas was significantly associated with being overweight among children. Limiting the number of fast-food outlets in residential areas could have a significant effect in reducing the prevalence of overweight among Malaysian children. - PublicationCessation of E-Cigarette Use Among Adults in Malaysia: Findings from a Nationwide Survey(2022)
;Muhammad Fadhli Mohd Yusoff ;Jane Ling Miaw Yn ;Thamil Arasu Saminathan ;Jamaluddin Ab Rahman ;Wan Shakira Rodzlan Hasani ;Tania Gayle Robert Lourdes ;Lim Kuang Hock ;Sumarni Mohd GhazaliMohamad Haniki Nik MohamedIntroduction: The use of e-cigarettes has increased rapidly around the world including in Malaysia. However, a significant proportion of people who started using e-cigarettes later discontinued using them. The aim of this study is to identify prevalence of former e-cigarette use and factors associated with quitting, among Malaysian adults. Methods: This study is a part of a national household survey examining the use of e-cigarettes among Malaysian adults aged 18 years and above in 2016. A multistage stratified cluster sampling method was used in the survey. A bilingual (Malay and English) structured questionnaire was used and data was collected via face-to-face interview. Prevalence of current e-cigarette use and former e-cigarette use were determined. A multiple logistic regression model was used to identify factors associated with quitting e-cigarettes. Results: A total of 4,288 adults participated in the survey, where 110 (3.2%) and 289 (8.6%) were identified as current and former e-cigarette users respectively. The following factors were significantly associated with quitting e-cigarette use: e-cigarette users who had no exposure to e-cigarettes at the workplace (aOR = 2.70; 95% CI: 1.39, 5.24); the perception that e-cigarette is more harmful to people compared to tobacco smoke (aOR = 2.46; 95% CI: 1.22, 4.97); and the perception that e-cigarettes do not help people to maintain cigarette abstinence (aOR = 2.19; 95% CI: 1.23, 3.92). Conclusions: This study contributes to a better understanding of the factors associated with cessation of e-cigarettes. Findings from this study can assist any e-cigarette cessation intervention measures such as strengthening on policy that prohibit e-cigarette use at workplace and increase advocacy on not using e-cigarette as a method to stop smoking. - PublicationImplementation of MPOWER Approach for Tobacco Control in Malaysia: Findings from the Global Adult Tobacco Survey (GATs)(2020)
;Heng Pei Pei ;Lim Kuang Hock ;Muhammad Fadhli Mohd Yusoff ;Teh Chien Huey ;Sumarni Mohamad Ghazali ;Lim Hui Li ;Kee Chee CheongLim Jia HuiIntroduction: Tobacco induced illness remains a major contribution to premature death and global burden of dis eases. The introduction of MPOWER policies by World Health Organization held the value to monitor the implementation of the anti-smoking measures in all signatory countries. This paper aimed to investigate the application of the six MPOWER indicators among Malaysia population. Methods: We utilized the data of Global Adult Tobacco Survey-Malaysia (GATS-M) which recruited 5112 nationally representative samples of Malaysians of 15 years old and above. Descriptive statistical analysis was used to illustrate the social demographic characteristic of the respon dents while cross tabulation was employed to describe all elements of the MPOWER indicators. Results: About one quarter (23.1%) of Malaysian adults were current tobacco users. The SHS exposure at home (38.4%) and restaurant (42.1%) were high. Approximately eight in ten (80.2%) of the smokers intended to quit, while for those attempted to quit in past one year, 9.0% utilized pharmacotherapy and 4.4% attended counseling. The awareness about tobacco related diseases was generally excellent. The overall tax make up of the cigarettes’ retail price ranging from 41.7% up to 80%. Conclusion: Tobacco consumption remains prevalent and plateau among Malaysian adults over the last two decades with substantial proportion of the population exposed to SHS. The inadequacy in the current anti-smoking policies needs urgent improvement in order to reduce the smoking norms among Malaysians population besides to achieve the ultimate goal of tobacco control end game by year 2045. - PublicationInadequate Iodine Intake among School Children in Terengganu- Findings from the National Iodine Deficiency Disorder Survey 2008(2013)
;Lim Kuang Kuay, ;Chan Ying Ying ;Ahmad Ali Zainuddin ;Teh Chien Huey ;Rusidah Selamat ;Kee Chee Cheong ;Hasimah IsmailLim Kuang HockIntroduction: Iodine deficiency is still prevalent worldwide and it is the main cause of goiter, thyroid dysfunction and mental retardation. The aim of the study was to determine the iodine status and goiter prevalence among the school children in Terengganu. Methods: The representative sample consists of 1163 primary school children aged 8-10 years old randomly selected from urban and rural schools in Terengganu using stratified systematic random sampling technique. Urinary iodine levels in spot urine were determined by in house modified micro-method whilegoiter assessment was carried out by palpation of thyroid gland. The status of iodine deficiency was determined by the median urinary iodine concentrations (UIC) and total goiter prevalence (TGP) in accordance with the WHO criteria. Results: The result showed the median [inter-quartile range (IQR)] urinary iodine concentrations was 78.7µg/L (50.1µg/L -120.0µg/L) indicating the iodine intake was slightly lower than recommended range of 100 µg/L. The rural school children had a significantly lower Iodine levels (median UIC=72.4µg/L, IQR=46.7µg/L -113.0µg/L) than the urban school children (median UIC=87.7µg/L, IQR=54.5 µg/L - 127.5µg/L). The total goiter prevalence (TGP) was 5.7%. The prevalence of goiter was significantly higher in rural (TGP=6.9%) compared to urban areas (TGP=3.6%). Conclusions: The study revealed that school children in Terengganu showed mild iodine deficiency and the condition is more pronounced in children from rural areas. The findings emphasize the importance of intervention implementation, universal salt iodization to ensure sufficient intake of iodine among the Terengganu school children. - PublicationIodine Status after a 3-Year Universal Salt Iodisation in Sarawak, Malaysia(2015)
;Lim Kuang Kuay ;Jambai Endu ;Chan Ying Ying ;Teh Chien Huey ;Hasimah Ismail ;Lim Kuang HockKee Chee CheongIntroduction: Following the reveal of borderline iodine sufficiency among the Sarawakians from the 2008 National Iodine Deficiency Disorders (IDDs) survey, a mandatory universal salt iodization (USI) was implemented in Sarawak thereafter. This study aimed to determine the current status of USI in Sarawak after a 3-year implementation of USI from 2008 to 2011. Methods: The IDD survey was conducted between Jun 2011 to July 2011 involving six districts in Sarawak (Sarikei, Mukah, Kapit, Sibu, Bintulu and Miri). The schools were selected via multistage proportionate-to-population size sampling technique and the children were randomly selected via systematic sampling. A total of 19 schools and 661 children were recruited into the survey. Thyroid size was determined by palpation and was and graded according to the classification of the World Health Organization (grade 0-2). The iodine excretion level in spot morning urine was measured using in-house microplate method. The urinary iodine concentration (UIC) values were compared by Kruskal-Wallis test and Chi-square tests were used to compare categorical variables. Results: A total of 610 school children were participated in the study (92.3%). The TGR of grade 1 and 2 was found to be 0.3% (n = 2). Overall the median UIC level was 154.2 (IQR, 92.7 - 229.8) µg/L, with the highest median UIC been observed in Sarikei [178.0 (IQR, 117.6 - 308.9) µg/L], followed by Mukah [174.8 (IQR, 99.0 - 224.3) µg/L)], Miri [158.6 (IQR, 92.3 - 235.4) µg/L], Sibu [147.0 (IQR, 89.8 - 221.4) µg/L], Bintulu [142.3 (IQR, 52.8 - 245.1) µg/L] and Kapit [131.0 (IQR, 88.6 - 201.9) µg/L]. One in every ten child was of iodine deficient (UIC < 50µg/L) while a third of the child (32%) were of adequate level of UIC. Conclusion: The present findings indicate that the mandatory USI successfully improves the iodine level of children in Sarawak. However, regular and proper monitoring of the UIC level in the communities is needed to prevent excessive iodine intake. - PublicationIs fast-food consumption a problem among adolescents in Malaysia? An analysis of the National School-Based Nutrition Survey, 2012(2021)
;Cheong Siew Man ;Lim Kuang Hock ;Chan Ying Ying ;Kee Chee Cheong ;Lim Kuang Kuay ;Teh Chien Huey ;Azli BaharudinNur Shahida Abdul AzizBackground: Fast-food consumption is an unhealthy dietary behaviour because it increases the risk of diet-related chronic diseases. We aimed to investigate factors associated with fast-food consumption, namely sociodemographic characteristics, body mass index-for-age, meal away from home habit, and intake of various food groups among adolescents in Malaysia. Methods: We analysed data from the National School-Based Nutrition Survey (NSNS). The NSNS was a nationwide, cross-sectional survey. Multiple-stage stratified cluster random sampling method was applied to obtain a representative sample of adolescents’ population. This study recruited adolescents aged 10–18 years who were attending schools. Pre-tested self-administered questionnaires in Malay language were used to obtain relevant information. Frequency of fast-food consumption per week was classified into three groups: “consumed fast-food four to seven days”, “consumed fast-food one to three days”, and “did not consume fast-food”. Intake of food groups was assessed by self-administered food frequency questionnaire. Descriptive and complex sample multinomial logistic regression analyses were performed in data analysis. Results: A total of 26,383 from 40,012 selected adolescents completed all the relevant questions for this study. Of those surveyed, 13.5% of the respondents consumed fast-food 4 to 7 days, 69.3% of the respondents consumed fast food 1 to 3 days, and 17.2% of them did not consume fast-food in a typical week. Frequency of fast-food consumptions (4 to 7 days and 1 to 3 days per week) was significantly associated with age; sex; ethnicity; locality of schools; frequency of eating out; and not consuming recommended intake of cereals or grains, vegetables, and meat or poultry or eggs. Conclusion: In conclusion, age; sex; ethnicity; locality of schools; frequency of eating out per week; imbalanced intake of cereals or grains, meat, or poultry or eggs; and inadequate vegetable intake were significantly associated with fast-food consumption among adolescents in Malaysia. The findings of this study will be useful for policy makers in promoting healthy food choices among adolescents in Malaysia. - PublicationPerceived Norm and smoking status among secondary school students in Kota Tinggi, Johor, Malaysia(2012)
;Lim Kuang Hock ;Sumarni Mohd Ghazali ;Kee Chee Cheong ;Hejar Abdul RahmanAmal Nasir MustafaIntroduction: Social norms, though an important contributing factor of adolescent smoking in developed countries, has not been extensively studied in Malaysia. The objective of this study was to determine the association between certain perceived norms regarding smoking with smoking status among Malaysian secondary school students in Kota Tinggi, Johor. Methods: Data were collected from 2311 respondents consisting of 1379 male and 923 female secondary school students in Kota Tinggi district via a self administered questionnaire. Five perceived norms regarding smoking were assessed, namely: perceived peer smoking prevalence, perceived parental reaction towards adolescent smoking, perceived public perception of adolescent smoking, ever noticed peers smoking inside and outside school and perceived enforcement of anti-smoking policy in school and their association with smoking status. Multiple logistic regressions controlling for gender, peer smoking and family smoking was performed. Results: Of the five perceived norms, four were associated with smoking status, (perceived peer smoking prevalence (p<0.001value), ever seen friends smoking inside or outside school (p <0.001), perceived parental reaction towards adolescent smoking (p<0.001 value) and perceived public disapproval (p <0.001)). Higher odds for smoking was observed for adolescents who: perceived a few (aOR 3.22), many (aOR 3.01) or a lot (aOR 3.52) of their peers smoke; had ever observed friends smoking in or outside of school (aOR 1.79); perceived their parents will react badly to smoking (aOR 0.84) or perceived the public disapprove of smoking (aOR 0.93). Conclusions: These results suggest that perception of social norms influence adolescents’ decision to smoke, thus measures to curb smoking incidence amongst adolescents should address these perceptions of social norms. - PublicationPerception of Harms and Benefits of Electronic Cigarettes Among Adult Malaysian Men: A Comparison by Electronic Cigarette Use and Smoking Status(2019)
;Caryn Mei Hsien Chan ;Jamalludin Ab Rahman ;Guat Hiong Tee ;Lei Hum Wee ;Bee Kiau Ho ;Noor Zurani Md Haris Robson ;Shamsul Draman ;Jane Ling Miaw Yn ;Lim Kuang Hock ;Muhammad Fadhli Yusoff ;Mira Kartiwi ;Norny Syafinaz Ab RahmanMohamad Haniki Nik MohamedLittle 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. - PublicationPrevalence And Factors Associated with Physical Inactivity Among Malaysian Adults(2014)
;Chan Ying Ying ;Lim Kuang Kuay ;Teh Chien Huey ;Lim Kuang Hock ;Hamizatul Akmal Abd Hamid ;Mohd Azahadi Omar ;Noor Ani AhmadKee Chee CheongUsing data from the Third Health and Morbidity Survey (NHMS III) in 2006, this study examined the association between socio-demographic factors and physical inactivity in a sample of 33,949 adults aged 18 years and above by gender. Physical activity levels were measured using the Global Physical Activity Questionnaire (GPAQvers 1). Physical inactivity was defined as having a total physical activity level of less than 600 metabolic equivalents-minutes per week (METsminutes/week) contributed by all three different life domains.Logistic regression analyses were conducted.The prevalence of overall physical inactivity was 43.7%(95% CI: 42.9-44.5). The mean total physical activity level was 894.2 METs-minutes/week. The means METs-minutes/week for the domain of work, travelling, and leisure time were 518A 288.1, and 134.8, respectively. Multivariable logistic regression analyses indicated that females were more likely to be physically inactive than males were (aOR=l.62; 95% CI: 1.53-1.72). Among women, being a housewife (aOR=l.78; 95% Cl: l.56-2.03t widow/divorcee (aOR=l.23; 95% CI: l.05-l.43t and those with no formal education (aOR=l.20; 95% Cl: 1.01-1.43) were found to be significantly associated with physical inactivity. Urban residents, older adults aged 65 years and above, private employees, nonworking group, and those with a monthly household income level of MYR5,000 and above appeared to be consistently associated with physical inactivity across men, women, and combined group (both). Specific health intervention strategies to promote physical activity should be targeted on population subgroups who are inactive - PublicationPrevalence and Factors Associated with Smoking Intentions among Non-smoking and Smoking Adolescents in Kota Tinggi, Johor, Malaysia(2014)
;Lim Kuang Hock ;Sumarni Mohamad Ghazali ;Kee Chee Cheong ;Lim Kuang Kuay ;Lim Hui Li ;Teh Chien Huey ;Chan Ying Ying ;Yeo Lay Yen ;Fiona Goh Swee Ching ;Khoo Yi Yi ;Chong Zhuo Lin ;Normala IbrahimAmal Nasir MustafaIntention to smoke is a valid and reliable factor for predicting future smoking habits among adolescents. This factor, however, has received inadequate attention in Malaysia. The present paper elaborates the prevalence and factors associated with intent to initiate or to cease smoking, among adolescent nonsmokers and smokers in Kota Tinggi, Johor, Malaysia. A total of 2,300 secondary school students aged 13-16 years were selected through a two-stage stratified sampling method. A set of standardized questionnaires was used to assess the smoking behavior among adolescents and the inter-personal and intra-personal factors associated with smoking intention (intention to initiate smoking or to cease smoking). Multivariable logistic regression was used to identify factors related to smoking intention. The prevalence of intention to smoke in the future or to cease smoking among non-smoking adolescents and current smokers were 10.7% and 61.7% respectively. Having friends who smoke, social influence, and poor knowledge about the ill effects on health due to smoking showed significant relationships with intention to smoke in the future among non-smokers. Conversely, perceived lower prevalence of smoking among peers, weak contributory social influence, and greater awareness of the ill effects of smoking are factors associated with the intention to cease smoking sometime in the future. The study found that prevalence of intention to initiate smoking is low among non-smokers while the majority of current smokers intended to cease smoking in the future. Existing anti-smoking programmes that integrate the factors that have been identified in the current study should be put in motion to reduce the prevalence of intention to initiate smoking and increase the intention to cease smoking among adolescents - PublicationPrevalence, awareness, treatment and control of Hypertension among the elderly: the 2006 National Health and Morbidity Survey III in Malaysia(2013)
;Ho Bee Kiau ;Jasvindar Kaur ;Balkish Mahadir Nainu ;Mohd Azahadi Omar ;Mohmad Saleh ;Yau Weng KeongLim Kuang HockIntroduction : The objective of this study was to determine the prevalence and factors associated with the awareness, treatment and control of hypertension among the elderly population in Malaysia. Methods: Analysis of secondary data from a cross-sectional national population based survey using stratified multistage sampling conducted from April to August 2006 throughout Malaysia National Health and Morbidity Survey III(NHMS III). Adults aged 60 and older who had participated in the survey were included in the study. Results: A total of 4954 respondents (14.3%) were elderly from the 34,539 respondents aged 18 years and above for hypertension module in NHMS III. A total of 4933 elderly had their blood pressure examined (giving a response rate of 99.6%). The overall prevalence of hypertension among elderly was 74.0%, more in elderly female (77.4%) than men (70.1%). Only 49.3% of them were aware of their hypertensive status, 42.4% were currently treated and 22.6% of those being treated were under control. The results of multiple logistic regression showed factors associated with higher awareness and treatment rates were similar i.e. females, young-old age group (age 60-74), urban residents, Chinese ethnic group and higher education. For those elderly who were on treatment, determinants associated with controlled hypertension were Chinese and Indians ethnic groups and higher educational level. Conclusions: There was a high prevalence of hypertension among the elderly in Malaysia but with poor awareness, treatment and control rate. Reliable information on these aspects is important for the development of patient education programs, health policies to improve disease management and overall health care resource allocation especially among the elderly in Malaysia. - PublicationSociodemographic factors associated with multiple cardiovascular risk factors among Malaysian adults(2015)
;Sumarni Mohd Ghazali ;Zamtira Seman ;Kee Chee Cheong ;Lim Kuang Hock ;Mala Manickam ;Lim Kuang Kuay ;Ahmad Faudzi Yusoff ;Feisul Idzwan MustafaAmal Nasir MustafaBackground: To determine the prevalence and sociodemographic correlates of multiple risk factors for cardiovascular disease (CVD) among Malaysian adults. Methods: We analysed data on 1044 men and 1528 women, aged 24–64 years, participants in the Non Communicable Disease Surveillance 2005/2006, a nationally representative, population-based, cross-sectional study. Prevalence of obesity, high blood pressure, dyslipidaemia, hyperglycemia, physical inactivity, smoking, risky drinking, low vegetable and fruit intake were determined and multivariable logistic regression was used to identify sociodemographic factors associated with having ≥3 of these cardiovascular disease risk factors. Results: The response rate was 84.6% (2572/3040). Overall, 68.4% (95% CI: 63.2, 73.1) had at least three risk factors. Among men, older age and Indian ethnicity were independently associated with having ≥3 CVD risk factors; while among women, older age, low education, and housewives were more likely to have ≥3 CVD risk factors. Conclusion: The prevalence of cardiovascular risk factors clustering among Malaysian adults is high, raising concerns that cardiovascular disease incidence will rise steeply in the near future if no immediate preventive measures are taken. The current national health education and promotion programmes pertaining to modifiable risk factors can be further improved by taking into account the sociodemographic variation in CVD risk factors clustering. - PublicationSupport for smoke-free policy among Malaysian adults: findings from a population-based study(BMJ PUBLISHING GROUP, 2019)
;Lim Kuang Hock ;Lim Hui Li ;Teh Chien Huey ;Veloo Yuvaneswary ;Pan Sayan ;Muhammad Fadhli Muhd Yusoff ;Lim Kuang Kuay ;Ling Miaw Yn ;Cheong Kee CheeGhazali Sumarni MohdObjective: Public opinion and support can be powerful mandates for smoke-free policy. However, the scarcity of evidence on public opinion among Malaysians necessitates further investigation. Therefore, this study aimed to determine the level of support for smoke-free policy at various public domains and its associated factors among Malaysian adults. Design: Data were derived from the Global Adult Tobacco Survey, Malaysia (GATS-M). GATS-M is a nationwide study that employed a multistage, proportionate-to-size sampling strategy to select a representative sample of 5112 Malaysian adults aged 15 years and above. Multiple logistic regression was used to identify factors associated with support for smoke-free policy in selected public domains that is, workplaces, restaurants, bars, hotels, casinos, karaoke centres, public transport terminals and shopping centres. Results The level of support for enactment of a smokefree policy at selected public domains varied from 37.8% to 94.4%, with the highest support was for gazetted smoke-free domains, namely, shopping centres (94.4%, 95%CI: 93.2% to 95.3%) and public transport terminals (85.2%, 95%CI: 83.3% to 86.9%). Multiple logistic regression revealed that non-smokers were more likely to support smoke-free policy at all domains. In addition, respondents who worked in workplaces with total or partial smoking restrictions were more likely to support a smoke-free policy ((total restriction adjusted OR (AOR): 14.94 (6.44 to 34.64); partial restriction AOR: 2.96 (1.138 to 6.35); non-restriction was applied as a reference). Conclusion A majority of the Malaysian adult population supported the smoke-free policy, especially at gazetted smoke-free domains. Therefore, expansion of a total smoking ban to workplaces, restaurants, bars, hotels, casinos and karaoke centres is strongly recommended to reduce exposure to secondhand smoke and to denormalise smoking behaviour.
