    BACKGROUND AND OBJECTIVES: Nutrition and physical activity interventions is beneficial in reversing obesity. However far too little attention has been paid to the effect of these interventions on breast tissues. Thus, the aim of this study was to explore the effect of a home-based dietary and physical activity intervention (the Her Shape Program) on metabolic parameters, blood biomarkers and adiposity at the breast.

    METHODS AND STUDY DESIGN: A randomized controlled study was conducted on obese women with high breast adiposity (<0.1 Sm-1), aged 40-60 years in Klang Valley, Malaysia. Subjects were assigned to intervention (n=16) and control group (n=15). Intervention group received a home based health education package with close monitoring weekly, personal diet consultation and physical training in group. Assessment was ascertained at three time points; baseline, weeks 8 and 16. Outcome measures were the energy intake, physical activity, body composition, blood tests, blood biomarkers and electrical impedance tomography (EIT) quantitative values. Analyses were done using 2-way repeated measures ANOVA.

    RESULTS AND CONCLUSIONS: All subjects completed the program without any drop-out. The HSI group had 100% compliance towards the intervention program; their energy intake was reduced for approximately 35% and their activity score was increased for approximately 11%. A significant interaction effect was found in body weight, body mass index (BMI), total cholesterol/HDL, vitamin C intake and matrix metallopeptidase 9 (MMP-9) (p<0.05). Interestingly, their EIT extremum values were also significantly increased indicating a reduction of breast adiposity. The intervention program was successful in improving body composition, physical activities, MMP9 and breast adipose tissue composition.

    The South East Asian Nutrition Surveys (SEANUTS) were conducted in 2010/2011 in Indonesia, Malaysia, Thailand and Vietnam in country representative samples totalling 16,744 children aged 0.5 to 12 years. Information on socio-demographic and behavioural variables was collected using questionnaires and anthropometric variables were measured. In a sub-sample of 2016 children, serum 25-hydroxy-vitamin D (25(OH)D) was determined. Data were analysed using SPSS complex sample with weight factors to report population representative data. Children were categorized as deficient (<25 nmol/L), insufficient (<50 nmol/L), inadequate (<75 nmol/L) or desirable (>=75 nmol/L). In Malaysia and Thailand, urban children had lower 25(OH)D than rural children. In all countries, except Vietnam, boys had higher 25(OH)D levels and older children had lower 25(OH)D. Regional differences after correcting for age, sex and area of residence were seen in all countries. In Thailand and Malaysia, 25(OH)D status was associated with religion. The percentage of children with adequate 25(OH)D (>=75 nmol/L) ranged from as low as 5% (Indonesia) to 20% (Vietnam). Vitamin D insufficiency (<50 nmol/L) was noted in 40 to 50% of children in all countries. Logistic regression showed that girls, urban area, region within the country and religion significantly increased the odds for being vitamin D insufficient. The high prevalence of vitamin D insufficiency in the (sub) tropical SEANUTS countries suggests a need for tailored approach to successfully combat this problem. Promoting active outdoor livestyle with safe sunlight exposure along with food-based strategies to improve vitamin D intake can be feasible options.

    Rats exposed to stress developed various changes in the gastrointestinal tract and hormones. The present study was designed to compare the impact of tocopherol and tocotrienol on changes that influence gastric and hormonal parameters important in maintaining gastric mucosal integrity in rats exposed to restrain stress. These include gastric acidity, gastric tissue content of parameters such as malondialdehyde, prostaglandin (PGE(2)), serum levels of gastrin and glucagon-like peptide-1 (GLP-1). Sixty male Sprague-Dawley rats (200-250 g) were randomly divided into three equal sized groups, a control group which received a normal rat diet (RC) and two treatment groups each receiving a vitamin deficient diet with oral supplementation of either tocopherol (TF) or tocotrienol (TT) at 60 mg/kg body weight. Blood samples were taken from half the number of rats (non-stressed group) after a treatment period of 28 days before they were killed. The remaining half was subjected to experimental restraint-stress, at 2 hours daily for 4 consecutive days (stressed groups), on the fourth day, blood samples were taken and the rats killed. The findings showed that the gastric acid concentration and serum gastrin level in stressed rats were significantly (P<0.05) reduced compared to the non-stressed rats in the control and TF groups. However, the gastric acidity and gastrin levels in the TT group were comparable in stressed and non-stressed rats. These findings suggest that tocotrienol is able to preserve the gastric acidity and serum gastrin level which are usually altered in stressed conditions. The PGE(2) content and the plasma GLP-1 level were, however, comparable in all stressed and non-stressed groups indicating that these parameters were not altered in stress and that supplementation with TF or TT had no effect on the gastric PGE2 content or the GLP-1 level. The malondialdehyde, an indicator of lipid peroxidation was higher from gastric tissues in the stressed groups compared to the non-stressed groups. These findings implicated that free radicals may play a role in the development of gastric injury in stress and supplementation with either TF or TT was able to reduce the lipid peroxidation levels compared to the control rats. We conclude that both tocopherol and tocotrienol are comparable in their gastro-protective ability against damage by free radicals generated in stress conditions, but only tocotrienol has the ability to block the stress-induced changes in the gastric acidity and gastrin level.

    A multidimensional assessment of nutritional and health status comprised of subjective global assessment (SGA), anthropometry function, biochemistry, dietary intake, social and health aspects was carried out on 820 older people (52.8% men and 47.2% women) from four rural areas of Peninsular Malaysia. A proportion of the subjects had been classified as either overweight (25.7%) or chronic energy deficient (20.3%). Although 49% of subjects had normal body weight, 68.4% have been classified as having mild to moderate malnutrition according to the SGA. Only 1.1% and 2.3% had low serum albumin and ferritin, respectively. Almost 80% of subjects, especially men, were at high risk of cardiovascular diseases on the basis of the assessment of total cholesterol and LDL-cholesterol. The majority of the subjects (87.2%) were fully independent in performing daily tasks, with men having a significantly higher score compared to women (p<0.001). However, men were less likely to be able to perform a flexibility test (50.7%) than were women (27.0%) (p<0.05). The mean energy intake for men (1412 +/- 461 kcal/d) and women (1201 +/- 392 kcal/d) were below the Recommended Nutrient Intake (RNI) for Malaysia, although this is a difficult assertion to make in an age-group which generally experiences declining energy expenditure. Moreover, 52.5% of men and 47.5% of women might have underreported their food intake. Dietary micronutrients most likely to be deficient were thiamin, riboflavin and calcium. It is concluded that a substantial proportion of rural elderly Malays had problems related to both undernutrition and overnutrition. An appropriate nutrition intervention program is needed to improve the nutritional status of rural elderly Malays.

    A population-based cross-sectional study was conducted in all states of Malaysia with the aim to determine the prevalence of obesity among Malaysians aged fifteen years and above and factors associated. A stratified two-stage cluster sampling design with proportional allocation was used. Trained interviewers using a standardized protocol obtained the weight and height measurements and other relevant information. Subjects with a body mass index >= 30 kg/m2 were labelled as obese. The results show that the overall national prevalence of obesity among Malaysians aged 15 years old and above was 11.7% (95% CI = 11.1 - 12.4%). The prevalence of obesity was significantly higher in females (13.8%) as compared to 9.6% in males (p< 0.0001). Prevalence of obesity was highest amongst the Malays (13.6%) and Indians (13.5%) followed by the indigenous group of "Sarawak Bumiputra" (10.8%) and the Chinese (8.5%). The indigenous group of "Sabah Bumiputra" had the lowest prevalence of 7.3%. These differences are statistically significant (p< 0.0001). Logistic regression analysis results show that there was a significant association between obesity and age, gender, ethnicity urban/rural status and smoking status. The prevalence of obesity amongst those aged >= 18 years old has markedly increased by 280% since the last National Health and Morbidity Survey in 1996.

    BACKGROUND AND OBJECTIVES: Assessment of the nutrition care process (NCP) knowledge, attitudes, practices, and perceived barriers (KAPB) of dietetics practitioners is imperative before NCP is implemented completely in dietetics practice. No questionnaire assessing NCP KAPB has been developed and validated. Hence, we developed an NCP KAPB questionnaire called the KAPB-NCP and established its content validity.

    METHODS AND STUDY DESIGN: A total of 116 items associated with sociodemographic characteristics (7 items), professional development (3 items), organisational culture's support for the NCP (2 items), knowledge (27 items), attitudes (39 items), practices (20 items), and perceived barriers to implementing the NCP (14 items) were generated for potential inclusion in the KAPB-NCP questionnaire. The questionnaire was reviewed online by an expert panel for its content validity. An in-depth review was conducted by the research team for evaluating the overall comprehensiveness of the questionnaire.

    RESULTS: In total, 87 of 100 items of the KAPB sections showed an excellent content validity index (CVI; k* >0.74), whereas 10 showed a satisfactory CVI (k*=0.60-0.74). Only 3 items had a low CVI (k* <0.40). According to the expert panel revisions and the in-depth review, 72 items were incorporated into the questionnaire.

    CONCLUSIONS: The KAPB-NCP questionnaire is a content-valid instrument that can assess NCP KAPB.

    BACKGROUND AND OBJECTIVES: Acne vulgaris is a common skin condition among adolescents and young adults. Its relationship with the dietary intake is highly debatable and equivocal. This study aimed to identify the association between acne vulgaris and dietary intake among Malaysians.

    METHODS AND STUDY DESIGN: A case-control study was conducted involving 57 acne vulgaris patients and 57 age-, gender- and ethnicity-matched controls. All participants were aged 14 and above. The Comprehensive Acne Severity Scale (CASS) was used to categorise patients (grades 2 to 5) and controls (grades 0 to 1). Information such as the demographics, family history, smoking habits and dietary intake were collected using a self-administered questionnaire.

    RESULTS: In the patient arm, the gender ratio of male to female was 1.5:1. 43 patients (75.4%) had a family history of acne vulgaris. No significant association was found for acne in patients with a history of smoking. Milk consumption was significantly higher in patients (63.2%, n=36) versus controls (43.9%, n=25), (OR=2.19, p<0.05). In addition, chocolate consumption was also significantly higher in patients (43.9%, n=25) versus controls (24.6%, n=14), (OR=2.4, p<0.05). No significant association was found with the intakes of sweets, potatoes, chips, nuts, yoghurt, ice-cream or carbonated drinks.

    CONCLUSIONS: Dietary intake of milk and chocolate may play a role in acne vulgaris. Prospective cohort and intervention studies are recommended to explore whether a causal relationship might obtain.

    Acarbose inhibits intestinal alpha-glucosidases resulting in diminished and delayed postprandial hyperglycaemia (PPH). Studies on effects of acarbose on postprandial lipaemia (PPL) have been inconclusive. Little is known about the effects of acarbose on PPH and PPL following intake of a polysaccharide diet. We studied 30 type 2 diabetic patients on dietary and/or oral hypoglycaemic agent(s). Thirty patients were recruited for food A (nasi lemak), 28 for food B (mee goreng) and 28 for food C (roti telur), which represent the typical diets of the three main races in Malaysia. Serial blood samples were taken at 15 min before and up to 240 min after each food intake, without acarbose. Subsequently, three doses of 50 mg acarbose were given orally and the same procedure was repeated the following day. There were significantly lower mean increments in plasma glucose levels after compared to before acarbose treatment 30, 45 and 60 min for food A and at 30, 45, 60, 120, 180 and 240 min for food C, but no significant difference was noted for food B. There was a significantly lower mean fasting glucose level after compared with before acarbose treatment following intake of food A and C but not food B. Short-term treatment with acarbose caused significant diminished and delayed PPH response with food A and C but not with food B. Acarbose was more effective in reducing PPH response in polysaccharide foods with a higher and earlier postprandial glucose peak than in those with a lower and lagged peak. There were no significant differences in the mean fasting or postprandial triglyceride levels before and after acarbose treatment, following intake of all three foods for up to 4 hours. Depending on the food absorption pattern, overnight low dose treatment with acarbose leads to diminished fasting and peak plasma glucose levels, and delayed PPH but insignificant reduction in postprandial lipaemia in poorly controlled type 2 diabetics following intake of racially different Malaysian food.

    This paper outlines the methodology to add glycaemic index (GI) and glycaemic load (GL) functionality to food DietPLUS, a Microsoft Excel-based Malaysian food composition database and diet intake calculator. Locally determined GI values and published international GI databases were used as the source of GI values. Previously published methodology for GI value assignment was modified to add GI and GL calculators to the database. Two popular local low GI foods were added to the DietPLUS database, bringing up the total number of foods in the database to 838 foods. Overall, in relation to the 539 major carbohydrate foods in the Malaysian Food Composition Database, 243 (45%) food items had local Malaysian values or were directly matched to International GI database and another 180 (33%) of the foods were linked to closely-related foods in the GI databases used. The mean ± SD dietary GI and GL of the dietary intake of 63 women with previous gestational diabetes mellitus, calculated using DietPLUS version3 were, 62 ± 6 and 142 ± 45, respectively. These values were comparable to those reported from other local studies. DietPLUS version3, a simple Microsoft Excel-based programme aids calculation of diet GI and GL for Malaysian diets based on food records.

    The number of older persons in Asia is expected to triple by 2050. Ageing is associated with non-communicable chronic diseases, malnutrition, and geriatric syndromes, which influences the burden on the cost related to healthcare, health outcomes, and the quality of life. Experts in the field of older adult nutrition from Asia, Australia, and Europe were invited to participate in a two-day workshop to review the available data, current policies and programs for the ageing population in different countries of Asia to identify the gaps in knowledge and to develop recommendations for action. In Asia, most of the data pertaining to health status, nutritional status, and nutrient intake of the older persons were mainly obtained by conducting studies in nursing homes or hospitals and small cohort studies. There were limited country-specific data on this population. Moreover, the available data pertaining to different countries were difficult to compare due to differences in the reporting format and reference values used. Although nutrition initiatives and policies were realized and public education was conducted to support the older persons, most of these efforts targeted the general population rather than the older persons population segment. In healthcare management, a higher amount of education is required pertaining to the knowledge of nutritional requirements and appropriate feeding of the older persons to reduce underfeeding and its consequences. The expert group recommended the use of a systematic approach for reviewing data pertaining to different countries, initiatives, and programs to further evaluate the available data to underpin future research.

    The objective of this study was to explore the perception of, feelings and attitudes toward overweight or obesity, and the perceived barriers to weight loss among native adults from lower socio-economic background. A total of six gender- and ethnic-specific focus groups consisted of 38 overweight and obese purposefully and criterion selected adults (21 women and 17 men), participated in this study. An unstructured discussion guide based on the study objectives were used for the focus groups. The results showed that some participants perceived themselves as ugly, felt ashamed of their body size and were frustrated because they did not desire to be overweight. Due to their excess weight, most also expressed they were less effective in their work performances. Although some participants had negative attitudes toward themselves because of excess weight, this appeared to link to self-stigmatization rather than anti-obesity discrimination. The participants remained in the Pre-contemplation stage of losing weight probably because of perceived barriers such as difficulty to resist eating, lack of know how and previous failed attempts to lose weight. Importantly, this study provided some evidence that individuals in the Pre-contemplation stage are unable to take action to lose weight, even if effective strategies are suggested.

    This study aimed to investigate the effects of parenteral nutrition (PN) administration of amino acids (AA) on physical changes among very low birth weight infants in a local hospital setting in Malaysia. A retrospective study was carried out at a hospital in Malaysia. Records of neonates prescribed PN in the neonatal unit in 2012 were screened for eligibility. A total of 199 premature neonates received PN support in the year 2012 and, of these, 100 fulfilled the inclusion criteria. The median value of AA intake on the first day of PN was 2.00 (<28 weeks group); 1.00 (28-31 weeks group) and 0.75 (>31 weeks group). Neonates in the <28 weeks group were more likely to receive AA at an earlier time and higher initial dose compared with the other age groups. The study also found that there was no statistically significant difference in the dose of AA on the first day of PN administration and that the significant variations in nutritional parameters among the subjects did not lead to differences in physical outcomes. This study identified that when PN is provided in the local hospital setting, it is likely that the current nutritional practices are inadequate to achieve the standard growth recommendations. Our findings call for a need to optimize AA and calorie intake since growth restriction is a morbidity which will affect the infants' growth and development. Current prescriptions for PN in this hospital need to be reviewed in order to improve patient outcomes.

    Anemia is the most prevalent nutritional deficiency during pregnancy. Except for a study conducted 10 years ago in Kelantan, Malaysia's available statistics are based on isolated small urban maternity hospital studies from the 1980s. There was therefore, a need for a large study at national level to estimate the magnitude of the problem in the country as well as to understand its epidemiology. This multi-center, cross-sectional study was conducted from February to March 2005, to assess the prevalence of anemia. Multistage stratified random sampling technique was used and 59 Ministry of Health (MOH) primary health care clinics were selected. Our final dataset consisted of 1,072 antenatal mothers from 56 clinics. The overall prevalence of anemia in this population was 35 % (SE 0.02) if the cut off level is 11 g/dL and 11 % (SE 0.03) if the cut-off level is 10 g/dL. The majority was of the mild type. The prevalence was higher in the teenage group, Indians followed by Malays and Chinese being the least, grandmultiparas, the third trimester and from urban residence. After multiple linear regression analysis, only gestational age remained significant. These findings are useful for our Maternal Health program planners and implementers to target and evaluate interventions. Work is in progress for outcomes and cost-effectiveness studies to best tackle this problem. In conclusion, the prevalence of anemia is 35% and mostly of the mild type and more prevalent in the Indian and Malays.

    A nutritional status survey of Orang Asli (Aboriginal) adults in Lembah Belum, Grik, has been conducted involving a total of 138 subjects. Jahai (58.7%) was the main ethnic group as compared to that of Temiar (41.3%). Based on the Body Mass Index (BMI) characteristics, the majority (63.2%) of the respondents were normal, 26.7% underweight and 10.1% were either overweight or obese. However, by using two different indices of waist circumference and waist-to-hip ratio, 1.6% and 10.8% of the total respondents revealed abdominal obesity, respectively. Measurement of mid upper arm muscle circumference (MUAMC) indicated that about 40% showed nutritional insufficiency whereas 0.8% showed over-nutrition. Body fat classification revealed that 53.4% of the respondents were thin, 45.8% at normal level and only 0.8% were obese. Student's t-test revealed a significant difference in anthropometric indices of body weight, height, MUAMC, triceps, sub-scapular, supra-iliac and body fat according to gender. Meanwhile, analysis of variance (ANOVA) showed significant differences in body weight, waist circumference, WHR and body fat according to different age categories. It was also found that those who smoked had lower BMI compared with non-smokers. Alcohol consumption was associated with higher BMI and WHR among the respondents. Pearson's correlation test between anthropometric measurements and socio-economic and demographic factors showed that ethnic group was the strongest variable.

    Clinical practice guidelines recommend objective nutritional assessments in managing chronic kidney disease (CKD) patients but were developed while referencing to a North-American population. Specific recommendations for assessing muscle mass were suggested (mid-arm circumference, MAC; corrected mid-arm muscle area, cAMA; mid-arm muscle circumference, MAMC). This study aimed to assess correlation and association of these assessments with dietary protein intake in a multi-ethnic Asian population of healthy and CKD patients.

    This was a cross-sectional study that investigated the relationship between nutrient intake and psychosocial factors with the overall rate of weight loss after bariatric surgery among patients who had undergone sleeve gastrectomy in University Kebangsaan Malaysia Medical Centre (UKMMC). Forty-three subjects (15 men and 28 women) were recruited for this study. Subjects completed assessment questionnaires including the Binge Eating Scale (BES), Beck Depression Inventory (BECK), Family Support Questionnaires, and the Index of Peer Relation (IPR). Results showed that the median overall rate of weight loss was 4.3±5.5 kg/month, which was lower when compared to the rate of weight loss at three months which was 5.0±5.6 kg/month. Pre-operative weight was the predictor of overall rate of weight loss (p<0.05, R²=0.52). Binge eating disorder (BED) and depression were also closely associated with each other after bariatric surgery (p<0.001, R²=0.46). Subjects with good compliance to dietary advice had lower scores on the binge eating scale. The mean caloric and protein intake was very low, only 562±310 kcal/day and 29.6±16.1 g/day. The intake of vitamin A, B-1, B-2, B-3, B-12, C, folate, and iron met the Malaysian Recommended Nutrient Intake (RNI). However, the RNI for calcium, zinc, selenium, vitamin D, and vitamin E was not met. In conclusion, although bariatric surgery had many health benefits, several factors hindered weight loss after bariatric surgery. Health care professionals should closely monitor patients after bariatric surgery.

    BACKGROUND AND OBJECTIVES: This study investigated the association of DRD2 Taq1A, Taq1B and Taq1D gene polymorphisms with eating behavior, the preference/intake frequency/craving of high-fat foods and obesity in 394 Malaysian adults (161 males, 233 females; 308 Chinese, 86 Indians; 67 obese, 327 non-obese).

    METHODS AND STUDY DESIGN: Eating behaviors namely Cognitive Restraint, Uncontrolled Eating and Emotional Eating scores were assessed by the Three Factor Eating Questionnaire-R18. The preference/intake frequency/craving of 26 common high-fat Malaysian foods was assessed using a 7-point hedonic scale. Anthropometric measurements were taken and Taq1 gene polymorphisms were genotyped by PCR-Restriction Fragment Length Polymorphism using DNA extracted from mouthwash samples.

    RESULTS: The overall minor allele frequencies of Taq1A, Taq1B and Taq1D according to ethnicities (Chinese/Indian) were 0.37/0.29, 0.39/0.28, 0.06/0.30, respectively; genotype and allele distributions of Taq1B and Taq1D were significantly different between ethnicities. Eating behaviorscores were not significantly different between gender and ethnicities. Those with A1 or B1 allele had lower Cognitive Restraint score and higher Uncontrolled Eating score, while those with A1/A1 or B1/B1 genotype had higher fast food preference. D1 allele was associated with increased starchy food craving and mamak (Malaysian Indian-Muslim) food preference, but not eating behavior scores. All three gene variants were not associated with obesity and adiposity.

    CONCLUSION: Taken together, we posit that three DRD2 Taq1 gene polymorphisms influence the eating behavior and preference/intake frequency/craving of certain high-fat foods in Malaysian adults, but their role in obesity and adiposity is still inconclusive and needs further investigation.
