    BACKGROUND: Obesity and metabolic syndrome is prevalent among Malaysian adolescents and has been associated with certain behavioural factors such as duration of sleep, screen time and physical activity. The aim of the study is to report the prevalence of overweight/obesity, metabolic syndrome and its risk factors among adolescents.
    METHODS: A multi-staged cluster sampling method was used to select participants from urban and rural schools in Selangor, Perak and Wilayah Persekutuan Kuala Lumpur. Participants underwent anthropometric measurement and physical examination including blood pressure measurement. Blood samples were taken for fasting glucose and lipids and participants answered a self-administered questionnaire. Overweight and obesity was defined using the extrapolated adult body mass index (BMI) cut-offs of >25 kg/m2 and >30 kg/m2, according to the International Obesity Task Force (IOTF) criteria. Metabolic syndrome was defined based on International Diabetes Federation (IDF) 2007 criteria.
    RESULTS: Data were collected from 1361 participants. After excluding incomplete data and missing values for the variables, we analysed a sample of 1014 participants. Prevalence of overweight and obesity in this population was 25.4% (N = 258). The prevalence of metabolic syndrome was 2.6% in the population and 10% among the overweight and obese adolescents. Participants who slept between 7 and 9 hours a day has a lower risk of developing metabolic syndrome OR 0.38(0.15-0.94).
    CONCLUSION: Our results provide the prevalence of metabolic syndrome in Malaysian adolescents. Adequate sleep between 7 and 9 hours per day reduces the risk of developing metabolic syndrome.

    BACKGROUND: Obesity and lack of physical activity are fast becoming a concern among Malaysian adolescents.

    OBJECTIVE: This study aims to assess physical activity levels among Malaysian adolescents and investigate the association between physical activity levels and body composition such as body mass index (BMI), waist circumference (WC) and percentage of body fat.

    SUBJECTS AND METHODS: 1361 school-going 13 year old multi-ethnic adolescents from population representative samples in Malaysia were involved in our study. Self-reported physical activity levels were assessed using the validated Malay version of the Physical Activity Questionnaire for Older Children (PAQ-C). Height, weight, body fat composition and waist circumference (WC) were measured. Data collection period was from March to May 2012.

    RESULTS: 10.8% of the males and 7.4% of the females were obese according to the International Obesity Task Force standards. A majority of the adolescents (63.9%) were physically inactive. There is a weak but significant correlation between physical activity scores and the indicators of obesity. The adjusted coefficient for body fatness was relatively more closely correlated to physical activity scores followed by waist circumference and lastly BMI.

    CONCLUSION: This study demonstrates that high physical activity scores were associated with the decreased precursor risk factors of obesity.

    BACKGROUND: Leptin (LEP) G-2548A (rs7799039), leptin receptor (LEPR) Q223R (rs1137101) and tumor necrosis factor (TNF)-α G-308A (rs1800629) gene variants have been reported to be associated with obesity, although results for subjects from different countries have been controversial. The aim of this study was to determine the prevalence of overweight and obesity in Malaysian adolescents and the association of these polymorphisms with overweight and obese or over-fat adolescents.
    METHODS: A total of 613 adolescents (241 Malay, 219 Chinese, 153 Indian) were enrolled. Anthropometric measurements of body mass index (BMI) and body fat percentage were used to classify subjects as controls (non-overweight/obese or normal fat) or as cases (overweight/obese or over-fat). Genomic DNA was extracted from oral buccal mucosa cells for genotyping using polymerase chain reaction-restriction fragment length polymorphism and data obtained were statistically analyzed.
    RESULTS: A total of 23.3% of subjects were overweight/obese whereas 11.4% were over-fat; there were significantly more overweight/obese and over-fat Indian and Malay adolescents compared to Chinese (P < 0.001). A allele was the minor one for LEPR Q223R and TNF-α G-308A in all ethnic groups, whereas G allele was minor for LEP G-2548A in Chinese and Malay adolescents, except for Indian adolescents. Indian male adolescents with AA genotype for LEP G-2548A were associated with overweight/obesity (P = 0.025; odds ratio, 3.64; 95% confidence interval: 1.15-11.54). Despite the lack of association observed for LEPR Q223R and TNF-α G-308A, Indian and Chinese subjects with AA risk genotype for LEPR Q223R/LEP G-2548A and TNF-α G-308A/LEP G-2548A, respectively, had increased mean BMI (P = 0.049, P = 0.016).
    CONCLUSIONS: Genotype distribution and association of these polymorphisms with overweight/obesity vary between ethnic groups and genders. Nevertheless, the LEP G-2548A risk allele may be associated with overweight/obese Indian male adolescents in Malaysia.

    The aim of this study is to investigate the prevalence of metabolic syndrome (MetS) and its predictors among Malaysian elderly. A total of 343 elderly aged ≥ 60 years residing low cost flats in an urban area in the central of Malaysia were invited to participate in health screening in community centers. Subjects were interviewed to obtain socio demography, health status and behavior data. Anthropometric measurements were also measured. A total of 30 ml fasting blood was taken to determine fasting serum lipid, glucose level and oxidative stress. MetS was classified according to The International Diabetes Federation (IDF) criteria. The prevalence of MetS was 43.4%. More women (48.1%) were affected than men (36.3%) (p<0.05). Being obese or overweight was the strongest predictor for MetS in men and women (p<0.05, both gender). High carbohydrate intake increased risk of MetS in men by 2.8 folds. In women, higher fat free mass index, physical inactivity and good appetite increased risk of MetS by 3.9, 2.1 and 2.3 folds respectively. MetS affected almost half of Malaysian elderly being investigated, especially women, and is associated with obesity and unhealthy lifestyle. It is essential to develop preventive and intervention strategies to curb undesirable consequences associated with MetS.

    Understanding the factors influencing physical activity (PA) in the Asia-Pacific region is critical, given the high prevalence of inactivity in this area. The photovoice technique explores the types of PA and factors influencing PA among adolescents in Kuching, Sarawak. A total of 160 photographs were collected from participants (adolescents, n = 22, mean age = 14.27 ± 0.7 years, and parents, n = 8, mean age = 48 ± 6.8 years). Data analysis used constant comparison methods of a grounded theory. The Analysis Grid for Environments Linked to Obesity was used to categorize PA factors. Study findings were centered on the concept of safety, facilities, parental restriction, friends, cultural traits, media, community cohesiveness, and weather. The central theme was "feeling unsafe" when being outdoors. To promote PA behavior, provision of PA facilities needs to be supported by other programs that build on peer support, crime prevention, and traffic safety, together with other educational campaigns.

    BACKGROUND: Overweight and obesity are defined as abnormal or excessive fat accumulation that may impair health. Body mass index is a simple index of weight-for-height that is commonly used in classifying overweight and obesity in adult populations and individuals.
    OBJECTIVES: A study was conducted to screen the medical students of AIMST University for overweight/obesity using Body Mass Index(BMI) and to determine the prevalence among them.
    MATERIALS AND METHODS: This is an institution based cross sectional study was conducted among 290 medical students using a pre-tested questionnaire and measured their Body Mass Index (BMI). Data obtained was analyzed statistically by calculating proportions.
    RESULTS: Out of 290 students who participated in the study, 45.2% were males. In the study, 14.8% were found to be overweight (BMI 23-24.9 kg/m2); 13.7% of males and 15.7% of females. Pre-obese students (BMI 25-29kg/m2) accounted for 15.9% of the total (males 18.3% and females 13.8%). 5.2% were found to be obese (BMI > 30 kg/m2): males 9.2% and females 1.9%. Also 14.8% were found to be underweight (males 12.2% and females 17.0%). The study group consisted of 63.8% Indian, 32.4% Chinese and 3.8% Malay students.
    CONCLUSIONS: The study reveals that the prevalence of overweight and obesity among the medical students of AIMST University is on the high, which is comparable to the findings of earlier studies conducted in Malaysia, reinforcing the need to encourage healthy lifestyle, healthy food habits and a physically active daily routine, among the adolescents and youth of this country.

    Obesity is a global health concern and has a great impact on countries in the Asia-Pacific region. Physical inactivity is a major risk factor for obesity, but physical activity levels are declining in much of this region. Increasing physical activity is a priority in many countries. Considerable research has been conducted on physical activity related to obesity in Western countries, but populations in the Asia-Pacific region differ in physical, psychological, social, and cultural ways that warrant local and regional research. The authors reviewed research conducted in the Asia-Pacific region that examined either the impact of physical activity interventions on obesity-related outcomes or the effect of behavior-change interventions on physical activity participation. The number of studies found was limited, and their samples and methods varied too much to draw conclusions. The authors recommend further research in the Asia-Pacific region using systematic protocols to permit sound conclusions to be drawn and promote informed action at local levels.

    Obesity is an emerging public health threat in the elderly population in developing countries. Hence, the Third National Health and Morbidity Survey has assessed 4746 individuals aged 60 years and older recruited through a household survey to determine the prevalence of adiposity using body mass index and waist circumference. The national's prevalence of overweight and obesity in men was 29.2% (95% confidence interval [CI] = 27.2-31.3) and 7.4% (95% CI = 6.4-8.6), respectively. However, the prevalence decreased with age. The figures in women were 30.3% (95% CI = 28.5-32.1) and 13.8% (95% CI = 12.5-15.2), respectively. The prevalence of abdominal obesity was 21.4% (95%CI = 20.2-22.6), with 7.7% (95% CI = 6.7-9.0) in men and 33.4% (95% CI = 31.4-35.3) in women. Predictors of adiposity include the following: Malay and Indian ethnicity, higher education level, higher household income, from urban area, and being married. In conclusion, adiposity affects about one third of the Malaysian elderly population, especially those of the younger age group, women, and those with higher socioeconomic status.

    INTRODUCTION: Obstructive sleep apnea (OSA) and obesity are serious, widespread public health issues.

    OBJECTIVE: To localize and quantify geometric morphometric differences in facial soft tissue morphology in adults with and without OSA.

    MATERIALS AND METHODS: Eighty adult Malays, consisting of 40 patients with OSA and 40 non-OSA controls, were studied. Both groups were evaluated by the attending physician and through ambulatory sleep studies. 3-D stereophotogrammetry was used to capture facial soft tissues of both groups. The 3-D mean OSA and control facial configurations were computed and subjected to principal components analysis (PCA) and finite-element morphometry (FEM).

    RESULTS: The body mass index was significantly greater for the OSA group (32.3 kg/m(2) compared to 24.8 kg/m(2), p < 0.001). The neck circumference was greater for the OSA group (42.7 cm compared to 37.1 cm, p < 0.001). Using PCA, significant differences were found in facial shape between the two groups using the first two principal components, which accounted for 50% of the total shape change (p < 0.05). Using FEM, these differences were localized in the bucco-submandibular regions of the face predominantly, indicating an increase in volume of 7-22% (p < 0.05) for the OSA group.

    CONCLUSION: Craniofacial obesity in the bucco-submandibular regions is associated with OSA and may provide valuable screening information for the identification of patients with undiagnosed OSA.

    The purpose of this study was to report on the estimates and distribution of body mass index in a sample of Malaysian adolescents. The study utilized a cross-sectional design and multi-stage random sampling of secondary schools to select 5 urban and 9 rural schools in Kedah and Penang. A total of 6555 male and female adolescents (11-15 years old) of Malay, Chinese and Indian ethnic groups were measured for weights and heights for body mass index calculation. Information on household demographic and socioeconomic were obtained from parents through self-administered questionnaires. Analyses of body mass index distribution by location, ethnicity, gender and age were conducted using Chi-square test of SPSS 11.5. More of the rural (12.1%) and urban (19.4%) adolescents were underweight and overweight, respectively. While in all ethnic, gender and age groups, rural adolescents were more likely to be underweight, more of the urban adolescents were overweight. The prevalence of underweight was highest among the Indians (19.2%) and lowest in Chinese (7.2%). The prevalence of overweight in the three ethnic groups was in the range of 18-19%. More male than female adolescents were underweight (15% vs 7.8%) and overweight (19.5% vs 16.7%). Consistent patterns were also observed across location, ethnic and age groups. As age increased, the prevalence of overweight decreased across the ethnic and gender groups. The reported findings can serve as current reference on body mass index distribution of Malaysian adolescents and a basis for future efforts in health and nutrition interventions for Malaysian children and adolescents.

    The sustained economic growth and increasing economic stability in the Asian region over the last three decades have been accompanied by changing lifestyles leading to significant changes in the food and nutrition issues facing Asian countries. The chronic diseases associated with excessive consumption of nutrients, especially fat, are becoming increasingly apparent. At the same time, Asia has a disproportionate share of the malnutrition problem. Underweight and stunting remain significant problems in many Asian communities, and micronutrient deficiencies of iron, iodine, and vitamin A continue to afflict large population groups. Effective data collection and analysis are essential to formulate and implement intervention programs to address both sides of the changing nutrition scenario in Asia.

    In Japan, much attention has been paid to NASH and NAFLD for the past several years and the prevalence of this disease entity has been estimated, and NASH is thought to be present in 10% of those who have fatty liver diseases. Other points out the prevalence of NASH in Japan as 6 to 8 hundred thousand patients. The last two or three decades have seen the evolution of Western-style life of near complete inactivity, energy-dense food choices and liberal fiscal resources to obtain them and other means to avoid physical activity. Moreover, what is increasingly apparent is that NASH and NAFLD is not a Western disease and many population groups in the Asia-Pacific region are particularly prone to type 2 diabetes. Thus, it is not surprising that NASH has increasingly been diagnosed in several regions in Asia including Indonesia, Malaysia, Philippines, Thailand and India.

    Factors related to overweight were examined in a cross-sectional survey that included 1612 women workers from 10 large electronics assembly factories in Peninsular Malaysia. Respondents were Malaysian citizens, direct production workers below the supervisory level, and had worked at least a year in the factory where they were presently employed. Heights and weights were taken to calculate the body mass index (BMI). Weights and BMI increased with increasing age. After adjusting for age, odds ratios for overweight were significantly raised for married women in relation to not married women (OR 1.5, 95% CI=1.15-2.02), lower secondary education in relation to higher than upper secondary education (OR 1.8, 95% CI=1.06-3.14), monthly income RM800-999 (OR 1.7, 95% CI=1.21-2.45) and >/=RM1,000 (OR 1.8, 95% CI=1.23-2.72) in relation to

    The aim of this study was to assess overweight or obesity and associated factors in school-going adolescents in the Association of Southeast Asian Nations (ASEAN) member countries. The analysis included 30,284 school children 13-15 years of age from seven ASEAN members participating in the Global School-based Student Health Survey (GSHS) between 2007 and 2013. The overall prevalence of overweight or obesity across seven ASEAN countries (excluding Brunei) was 9.9%, significantly higher in boys (11.5%) than in girls (8.3%). Among eight ASEAN countries, the highest prevalence of overweight or obesity was in Brunei Darus-salam (36.1%), followed by Malaysia (23.7%), and the lowest was in Myanmar (3.4%) and Cambodia (3.7%). Multivariate logistic regression analysis found that younger age, coming from an upper middle country, never been hungry, and not walking or biking to school were associated with overweight or obesity. In addition, among boys, having three or more servings of vegetables per day and having no close friends, and among girls, having fast foods two or more times per week, been victims of bullying and having peer support were additional factors associated with overweight or obesity. Increased strategies utilizing a number of the risk factors identified are needed to prevent and treat overweight or obesity in adolescents in ASEAN member countries.

    The study investigated the association between breakfast types consumed, daily energy intake, and body mass index for age Z-score (BAZ). Cross-sectional data from 1258 children aged 7 to 12.9 years were analyzed for breakfast type, nutrient intakes, BAZ, and proportion of overweight or obesity. Analysis of covariance was used to compare energy and nutrient intakes, BAZ, and proportion of overweight/obese children between breakfast groups. Only 19% of children had adequate energy intake from breakfast. Those consuming snacks had a significantly lower BAZ (Z = -0.73), with 5% of them being overweight/obese. Those consuming beverages and desserts had the lowest total daily energy intake (1314 kcal) and lowest protein intake (8.4 g). The results suggest that breakfast type is associated with daily energy intake and BAZ. Most breakfasts are not adequate. School-based nutrition education programs involving families, teachers, and health professionals can contribute to improve this situation.

    The accelerated phase of industrialisation and urbanisation in recent decades has inevitably brought about changes in the lifestyle of Malaysians. Changes in dietary habits and sedentary lifestyles are known to be associated with changes in health and increased prevalence of chronic diseases in the population. The objective of this paper is to provide a better understanding of the link between demographic variables and food consumption patterns related to the nutrition transition in Malaysia. This review uses various reports and publications from several ministries and selected local studies. The statistics compiled over the last two decades have shown that as the population achieves affluence, intakes of calories, fats and sugars increase, which may account for the substantial increase in food importation bills over the same period. Similarly, the rapid growth of the fast food industry during the last decade has added another dimension to the change in food consumption patterns of Malaysians. With the exception of a study on adolescents, the prevalences of overweight and obesity in children and adults are not strictly comparable due to the difference in body mass index (BMI) cut-off points in children and the study protocol in adults, and hence should not be misinterpreted as trends. The recent recommendation to lower the BMI cut-off points for Asians would only increase the magnitude of the existing prevalence among adults. The need to promote healthy nutrition for the population must be pursued vigorously, as the escalation of nutrition-related chronic degenerative diseases - once an urban phenomenon--has now spread to the rural population at an alarming rate. This paper indicates that the problem is real and needs urgent attention because it may be just the tip of the iceberg.
