A 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.

Introduction: Mortality estimates are important parameters for health monitoring and are routinely used as evidence for health policy and planning. This study aimed to estimate the mortality component of Burden of Disease in Malaysia in 2008. Methods: The 2008 mortality data from the Statistics Department were used to estimate cause-specific mortality (by age and sex) in Malaysia. Data were coded using the ICD10 (International Classification of Disease) coding. Calculation of mortality component of Burden of Disease (ie: Years of Life Lost (YLL) was done using the standard Global Burden of Disease Methodology. Results: The total estimated deaths in Malaysia in 2008 were 124,857, of which 72,202 (57.8%) were males. The total years of life lost (YLL) for the Malaysian population in 2008 was 1.51 million in which 0.92 million (60.7%) was among males. Almost three quarter (68%) of the burden of premature deaths resulted from non-communicable diseases, followed by communicable diseases (20%) and injury (12%). Among the top three leading causes of YLL were ischaemic heart disease (17.1%), stroke (9.6%) and road traffic injuries (8.3%). Conclusions: In Malaysia, premature mortality mainly contributed by non-communicable diseases followed by communicable diseases and injury. A multi-agency collaboration is needed to prevent premature death and to improve quality of life.

Introduction: 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.

Introduction: 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.

Introduction Iodine deficiency disorders (IDD), is one of the most important micronutrient deficiencies which has multiple adverse effects on growth and development. The aim of this study was to determine the prevalence of IDD among school children and to elucidate the distribution of iodized salt at household level in Sarawak, East Malaysia. Methods This cross-sectional study was conducted among school children aged 8 to 10 years in 2008. A multi-stage probability proportionate to population size (PPS) cluster sampling method was used to obtain a representative state sample of 1200 school children. Spot urine samples were collected for the determination of urinary iodine concentration while the iodine content in salt was determined using field rapid test kits. The thyroid status was determined by palpation. Results Response rate was 92.0% (n=1104/1200). The prevalence of goitre among school children in Sarawak was 2.9% (5.2% in urban, 0.7% in rural). The median urinary iodine concentration (UIC) among the school children was 102.1 µg/L (IQR, 62.3-146.5 µg/L). Urban children had significantly higher median UIC of 109.3 µg/L (IQR, 72.4-159.0 µg/L) than their rural counterparts [91.9 µg/L (IQR, 55.7-140.2 µg/L)]. The salt samples tested by rapid test kit (RTK) showed only 46.0% of household salt contained iodine. Conclusions The present study revealed that the population in Sarawak were of borderline iodine sufficient with mild IDD seen in rural areas. Hence, the state IDD control programmes need to encourage and advocate the consumption of iodized salt in order to eliminate IDD-related health problems in Sarawak.

Introduction: 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.

Background: 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.

Using 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

Intention 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

Objective: 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.
