Introduction: Child malnutrition continues to be a major public health problem in developing countries. This study aims to determine the current nutritional status of Malaysian school children using the anthropometric indicators of weight for age (WAZ), height for age (HAZ), and body mass index for age (BAZ). Methods: A nationwide school-based survey was undertaken in all Malaysian states and territories, which included 18,078 children aged 8-10 years attending 445 primary schools. The software WHO AnthroPlus was used to calculate zscores for the nutritional status (WAZ, HAZ and BAZ) of the target population relative to the World Health Organization (WHO) 2007 reference. Results: The national prevalence of underweight among school children was 13.6% and in rural areas, this rate was nearly double that of urban areas. The national prevalence rate for stunting was 10.9%, double among rural school children compared to their urban counterparts. As for thinness, the national prevalence was 6.5%. Using the WAZ indicator, we found that the national prevalence of overweight children was 7.6%. Additionally, we found that urban areas showed a higher prevalence of overweight children (8.8%) than rural areas (5.9%). Conclusion: The findings of this study indicate that Malaysian school children face the burden of malnutrition, suffering from both undernourishment and overweight. Malaysia must make a concerted effort to overcome the problems of malnutrition among children.

BACKGROUND: The urinary iodine micromethod (UIMM) is a modification of the conventional method and its performance needs evaluation. METHODS: UIMM performance was evaluated using the method validation and 2008 Iodine Deficiency Disorders survey data obtained from four urinary iodine (UI) laboratories. Method acceptability tests and Sigma quality metrics were determined using total allowable errors (TEas) set by two external quality assurance (EQA) providers. RESULTS: UIMM obeyed various method acceptability test criteria with some discrepancies at low concentrations. Method validation data calculated against the UI Quality Program (TUIQP) TEas showed that the Sigma metrics were at 2.75, 1.80, and 3.80 for 51+/-15.50 microg/L, 108+/-32.40 microg/L, and 149+/-38.60 microg/L UI, respectively. External quality control (EQC) data showed that the performance of the laboratories was within Sigma metrics of 0.85-1.12, 1.57-4.36, and 1.46-4.98 at 46.91+/-7.05 microg/L, 135.14+/-13.53 microg/L, and 238.58+/-17.90 microg/L, respectively. No laboratory showed a calculated total error (TEcalc) Humans ; Iodine/*urine ; Laboratories/standards ; Quality Control ; Spectrophotometry/*standards ; Urinalysis/*standards

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. 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 while goiter 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. 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%). 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.

Food insecurity affects food intake, and it could prevent an individual from consuming enough nutritious food to support and maintain health. The aim of this paper is to determine the prevalence and factors influencing food insecurity among Malaysian households. In 2014, the Malaysian Adult Nutrition Survey (MANS) was carried out, and one of the components measured was food insecurity. Six out of sixteen questions from the food security core-module questionnaire were adopted and answered by 2962 adults. The results showed that about 25.0% adult experienced food quantity insufficiency, 25.5% had food variety insufficiency, 21.9% practised reduced size of the meal, and 15.2% skipped main meal due to lack of money to spend on. For the parents, 23.7% only rely on cheap food to feed children, and 20.8% could not afford to purchase various foods to feed their children. Location, strata, race, level of education, working status and household income shows significant difference while none of the nutritional status components found to be difference in all six parameters of food insecurity measured. Logistic regression with adjusted odds ratios discovered race, education level and household income were related to risk to all six parameters of food insecurity. In conclusion, food insecurity can be a serious problem in Malaysia. An effective and comprehensive effort by the government in terms of policy solution is required to increase education level and ensure an adequate income for every household. Therefore, future research should focus on some of those promising policy solutions and at the same time, study the other possible underlying factors that may lead to food insecurity.

Malnutrition can be associated as one of the factors which affect health status. The term is used to describe imbalance of nutrients either over- or under-nourished, resulting in measurable adverse effects on body composition, function and clinical outcome. The National Health And Morbidity Survey (NHMS) 2011 assessed 4304 individuals aged 10-17 years old through a household survey of Malaysian population. Thinness and obesity are the malnutrition indicators based on Centre for Disease Control (CDC) 2000 classification as recommended by WHO (2007). The findings of the survey showed that the national prevalence of thinness (BMI for age <-2SD), was 9.7% (95% Confidence Interval: 8.4-11.2). The state of Sabah/Labuan had the highest thinness of prevalence, 17.0% (11.1-25.2) and lowest in Penang at 5.3% (2.7-10.0). The prevalence of thinness was higher in urban areas than in rural areas at 10.3% (8.5-12.3). Meanwhile; national prevalence of obesity (BMI for age ≥+2SD) was only 5.7% (4.9-6.7). The state of Perak had the highest obesity prevalence 10.0% (6.2-15.8) and lowest in Sabah/Labuan at 2.4% (1.4-4.1). The obesity prevalence was higher among adolescents in urban areas at 6.3% (5.2-7.6) than in rural areas. Thinness as a form of malnutrition is more prevalent than obesity. Even though the prevalence of obesity is low, the impact affects not only the adolescents, but also the family, the society and the nation in the future. The increasing prevalence of obesity will have significant public health implication related to non-communicable diseases.

​Overweight and obesity is a major public health problem in Malaysia. This study aims to determine the prevalence of overweight and obesity among the Malaysian adult population and their association with socio-demographic characteristics (gender, ethnic, and age groups). A total of 17,257 adults aged 18 years and older (8,252 men, 9,005 women) were assessed for BMI status, with a response rate of 97.8%, through a household survey from the National Health and Morbidity Survey (NHMS), conducted in all states of Malaysia in 2011. All socio-demographic factors were consistently associated with higher chance of being overweight (except gender and location) and obesity (except location and household income). The identified risk of overweight were Indian (aOR: 1.8, 95% CI: 1.2-2.8), aged 50-59 years (aOR: 2.8, 95% CI: 2.0-3.9), widower (aOR: 1.6, 95% CI: 1.3-2.0), subject with secondary education (aOR: 1.2, 95% CI: 1.0-1.4), Homemaker/unpaid worker (aOR: 1.3, 95% CI: 1.1-1.4), and with high household income group (aOR: 1.3, 95% CI: 1.2-1.6). The identified risk of obesity were women (aOR: 1.4, 95% CI: 1.2-1.6), Indian (aOR: 1.7, 95% CI: 0.9-3.2), aged 30-39 years (aOR: 3.6, 95% CI: 2.4-5.5), widower (aOR: 1.2, 95% CI: 0.9-1.6), subjects with primary education (aOR: 1.2, 95% CI: 0.9-1.6), Homemaker/unpaid worker (aOR: 1.3, 95% CI: 1.1-1.6), and with middle household income group (aOR: 1.3, 95% CI: 1.2-1.6). Our data indicate a high prevalence of overweight and obesity in the population. Several sociodemographic characteristics are associated with both overweight and obesity. This study highlights the serious problem of overweight and obesity among Malaysia adults. Documentation of these problems may lead to research and policy agendas that will contribute both to our understanding and to the reduction of these problems.

Introduction: Adequate daily intake of fruits and vegetables is crucial for the prevention of chronic diseases. This study aimed to determine the effects of My Body is Fit and Fabulous at School (MyBFF@school) with nutrition education intervention (NEI) on the stages of change for fruit and vegetable intake among overweight and obese secondary school children based on the trans-theoretical model (TTM). Methods: This was a cluster randomised controlled trial involving 15 out of 415 eligible government secondary schools in central Peninsular Malaysia, which were randomly assigned into intervention (six schools; 579 school children) and control (nine schools; 462 school children). The intervention group was given NEI for 24 weeks, while the control group followed the existing school programme by the Ministry of Education. Results: There was no significant difference between the intervention and control groups for the stages of change, with majority at the maintenance stage after six months (intervention: 34.9%; control: 39.0%). The within group analysis showed a significant reduction after six months for those at the action stage (action and maintenance stage) from 68.0% to 60.4% in the intervention group and from 71.4% to 65.6% in the control group. However, there was a significant increase among those with adequate fruit and vegetable intake in the intervention group and no significant increase in the control group. Conclusion: MyBFF@school with NEI based on TTM provided acceptable changes in fruit and vegetable intake among overweight and obese secondary school children.

Introduction: Access to accurate and timely dietary information is of paramount importance in evaluating and developing well-targeted public health nutrition interventions. However, nationwide nutrition surveys are conducted infrequently because they are very costly to design, conduct and analyse. Dietary assessment tools, which are quick and cost- effective, are needed for population research and regular monitoring of Malaysians’ dietary habits. This paper describes the rationale and methodology of the Malaysian Healthy Diet Online Survey (MHDOS) project, which aims to bridge this knowledge gap on dietary intake of Malaysian adults. The main objective of the two-year project is to develop MHDOS as a valid tool to measure compliance with the Malaysian Dietary Guidelines 2020. Methods: The MHDOS project has three study phases, namely (i) adaptation of an online survey and established diet quality scoring system for Malaysia, (ii) usability, validity and reliability testing of the online survey; and (iii) online survey administration in a nationwide study. The survey will be administered to approximately 10,000 Malaysian adults aged 18-59 years. Discussion: MHDOS consists of 38 questions that measures the quantity, quality and variety of foods consumed. Individuals will receive a diet quality score that reflects their overall compliance with the Malaysian Dietary Guidelines and feedback on how to improve their scores. The findings of the online survey, which serve to complement information between larger surveys, will be useful to measure compliance of Malaysians to national dietary guidelines and inform public health interventions.
