Malaysian Journal of Nutrition.2014;20(1):63-70.

Low levels of serum 25(OH)D in women are reported in temperate countries, and increasingly so in tropical countries but few such studies have been reported in Indonesia. This study was aimed at assessing the serum vitamin D status and its associated factors in a sample of Indonesian women Methods: A cross-sectional study was conducted on 156 apparently healthy women during the dry season in North Sumatera. The measurements carried out included exposure to sun's rays, intake of vitamin D food sources, reported physical activity, body fatness (by bioelectrical impedance analysis), and serum 25(OH)D levels (by chemiluminescent immunoassay). Serum 25(OH)D levels were categorised into: deficient(<20 ng/mL), insufficient (20-32 ng/mL), sufficient (32-100 ng/ mL), and normal for tropical countries (54-90 ng/mL). Statistical analysis included Pearson correlation, independent t-test, and one way ANOVA tests. Results: The mean age of the subjects was 35.6±7.7 years, with about 70% working indoors. About half of the women were obese. The majority had low vitamin D intake. More than half had sun ray exposure of less than 1 hour, and moreover, nearly two-thirds of them wore the 'hijab' that covers most parts of their body. The majority of women reported low physical activity level. The mean serum 25(OH)D level of the subjects was 17.71 ng/mL (95% CI: 16.22, 19.34 ng/mL). Of the total, 95% (148) were in the vitamin D deficient-insufficient category, with the remaining 5% in the sufficient category. An association was found between occupation, dietary intake of vitamin D, sun ray exposure, and physical activity levels with serum vitamin D concentrations. Conclusion: The results showed that vitamin D deficiency can occur in women living in a tropical country if they have sun-avoiding lifestyles, work indoors, and have low dietary intake of vitamin D.

Malaysian Journal of Nutrition.2011;17(2):249-258.

Introduction: Methylenetetrahydrofolate reductase (MTHFR) C677T is involved in folate and homocysteine metabolism. Disruption in the activity of this enzyme will alter their levels in the body. Methodology: This study assessed MTHFR C677T polymorphism and its relationship with serum homocysteine and Bvitamins levels in a sample of Chinese and Malays subjects in UPM, Serdang. One hundred subjects were randomly selected from among the university population. Folate, vitamin B12, B6, and homocysteine levels were determined using MBA, ECLIA, and HPLC, respectively. PCR coupled with HinfI digestion was used for detection of MTHFR C677T polymorphism. Results: The frequency of T allele was higher in the Chinese subjects (0.40) compared to the Malay (0.14). Folate, vitamin B12 and B6 levels were highest in the wild genotype in both ethnic groups. Subjects with heterozygous and homozygous genotype showed the highest homocysteine levels. The serum folate and homocysteine were mainly affected by homozygous genotype. Conclusion: MTHFR C677T polymorphism plays an important role in influencing the folate and homocysteine metabolism.

The home environment plays an influential role in affecting dietary and physical activity practices of children. This study aimed to determine the association between the home environment, dietary practice and physical activity among primary school children in Selangor. Methods: This cross-sectional study was conducted in five primary schools selected using multistage stratified sampling. A total of 293 children (32.8% males and 67.2% females) (mean age of 11.0±0.9 years) and their parents (10.7% fathers and 89.3% mothers) completed the study. Dietary practice of the children was assessed using a two-day dietary recall. Energy expenditure and physical activity of the children were assessed using a two-day physical activity recall. Parents of the children completed the Home Environment Survey (HES). Results: The mean energy intake of the children was 1765±416 kcal/day with 75.0% not achieving the Malaysian Recommended Nutrient Intake (RNI) for energy. Almost all children (96.5%) were physically inactive, with a mean energy expenditure of 12693±42 kcal/day. High availability of fruit/vegetable at home was associated with high vegetable intake (r=0.128, p<0.05) and low fat intake (r=-0.115, p<0.05). High availability of fats/sweets at home (r=0.125, p<0.05) and parental role modelling of healthy eating (r=0.117, p<0.05) were associated with high fruit intake. High availability of physical activity equipment at home was associated with high energy expenditure (r=0.123, p<0.05). Parental role modelling of physical activity was associated with high energy expenditure (r=0.123, p<0.05) and high physical activity (r=0.123, p<0.05). Conclusion: The results indicate the important roles of parents in promoting healthy eating and active lifestyles among children.

Datta Banik S

Malaysian Journal of Nutrition.2014;20(1):39-49.

Age at menarche (AM) is an important growth and maturity indicator in girls. Pre- and post-menarcheal age-peers differ in BMI-based nutritional status and growth of linear dimensions of body measurements. Methods: Using a cross-sectional approach, body size and nutritional status were evaluated in pre-menarcheal (n=50) and post-menarcheal (n=50) school-going Hindu girls aged 10.0 to 12.87 years. All were from socio-economically poor families in a rural area of Kashipur, Purulia district, West Bengal state, India. Anthropometric parameters included the following: height; body weight; body mass index (BMI); sitting height (SH); subischial leg length (SLL); knee height (KH); bi-acromial diameter (BAD); bi-iliocristal diameter (BILCD); and hip breadth (HB). Z-scores of height-for-age (HAZ) and BMI-for-age (BMIZ) were calculated following WHO to evaluate stunting (low HAZ) and thinness (low BMIZ) Results: The mean age was 11.12 years for pre-menarcheal girls and 11.32 years for post-menarcheal girls. Mean and median AM were 10.52 years and 10.80 years respectively. Post-menarcheal girls had higher mean anthropometric characteristics than pre-menarcheal girls with significant difference (p< 0.05). Undemutrition was frequent among girls, including stunting (pre-menarcheal 62%, post-menarcheal girls 38%), thinness or low BMI-for-age (pre-menarcheal 16%, post-menarcheal 28%), and composite burden of stunting and thinness (pre-menarcheal 14%, post-menarcheal girls 18%). Girls with low BMI-for-age had shorter SH, SLL, KH, BAD, BILCD, and HB. Linear combination of body dimensions significantly (p< 0.05) predicted post-menarcheal status through binary logistic regression analysis. Conclusion: Pre-menarcheal girls experienced a higher degree of chronic undernutrition (stunting). Post-menarcheal girls showed a greater body size than pre-menarcheal age-peers.

Malaysian Journal of Nutrition.2014;20(1):51-62.

The aim of the study was to evaluate the association between physical activity level, sedentary behaviour and eating habits with obesity indices of body mass index (BMI) and waist-to-height ratio (WHtR)) among Jordanian adolescents. Methods: A cross-sectional study was conducted in the capital city of Jordan, Amman. The participants were 735 secondary school males (386) and females (349) aged 14-18 years who were randomly selected using a multistage stratified cluster sampling technique. Weight, height, BMI, waist circumference (WC), WHtR, screen time, physical activity level, and eating habits were assessed. Results: Compared with males, females were significantly (p<0.05) less physically active, skipped breakfast more frequently, consumed more sweets and potato chips and had less fruits and milk intake. The results of analysis of covariance showed that overweight and obesity (based on BMI or WHtR categories) were significantly (p< 0.05) different with regard to gender, type of school, lower intakes (<3 d/week) of breakfast, milk and sugar sweetened drinks. Conclusion: Knowledge of the factors that contribute to obesity could be used in preventive programmes for the control of obesity among adolescents in Jordan. Promotion of physical activity and healthy dietary habits among Jordanian adolescents is urgently needed.

No Association of Peptide Tyrosine-Tyrosine (PYY) Gene R72T Variant with Obesity in the Kampar Health Clinic Cohort, Malaysia

Chan PM ; Fan SH ; Say YH

Malaysian Journal of Nutrition.2011;17(2):201-212.

Introduction: Peptide Tyrosine-Tyrosine (PYY) is a 36-amino acid peptide hormone released post-prandially from the endocrine cells in the intestinal tract to suppress pancreatic secretions and eventually reduce appetite. The R72T variant in the PYY gene (rs1058046) has been associated with increased susceptibility to obesity. Therefore, the objective of this study was to investigate the association of this variant with obesity and its related anthropometric measurements among the Kampar Health Clinic cohort, Malaysia. Methodology: A total of 197 (78 males, 119 females; 98 non-obese, 99 obese) subjects were recruited by convenience sampling and anthropometric measurements were taken. Genotyping was performed using StuI Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP), revealing 61 RR, 94 RT and 42 TT subjects. Results: Most of the obese subjects had the RT genotype (50.5%), while only 18.2% were TT. PYY R72T genotypes and alleles had no association with obesity (p=0.535; 0.074, respectively), gender (p=0.767; p=0.100, respectively) but were associated with ethnicity (p=0.003; p=0.002, respectively). Among the 13 anthropometric measurements taken, significant difference was only found in Waist Circumference (WC) and Visceral Fat Level (VFL) among the alleles, suggesting that subjects with T allele will have an increment of 1.82 cm in WC and 1.32% in VFL. Conclusion: The R72T variant in PYY gene was not associated with obesity and most of its related anthropometric measurements. This suggests that other genes and/or environmental factors like dietary habits and lifestyle factors may be the contributors of obesity.

Gan WY ; Mohd Nasir MT ; Zalilah MS ; Hazizi AS

Malaysian Journal of Nutrition.2011;17(2):213-228.

Introduction: University students are potentially important targets for the promotion of healthy lifestyles as this may reduce the risks of lifestyle-related disorders later in life. This cross-sectional study examined differences in eating behaviours, dietary intake, weight status, and body composition between male and female university students. Methodology: A total of 584 students (59.4% females and 40.6% males) aged 20.6±1.4 years from four Malaysian universities in the Klang Valley participated in this study. Participants completed the Eating Behaviours Questionnaire and two-day 24-hour dietary recall. Body weight, height, waist circumference and percentage of body fat were measured. Results: About 14.3% of males and 22.4% of females were underweight, while 14.0% of males and 12.3% of females were overweight and obese. A majority of the participants (73.8% males and 74.6% females) skipped at least one meal daily in the past seven days. Breakfast was the most frequently skipped meal. Both males and females frequently snacked during morning tea time. Fruits and biscuits were the most frequently consumed snack items. More than half of the participants did not meet the Malaysian Recommended Nutrient Intake (RNI) for energy, vitamin C, thiamine, riboflavin, niacin, iron (females only), and calcium. Significantly more males than females achieved the RNI levels for energy, protein and iron intakes. Conclusion: This study highlights the presence of unhealthy eating behaviours, inadequate nutrient intake, and a high prevalence of underweight among university students. Energy and nutrient intakes differed between the sexes. Therefore, promoting healthy eating among young adults is crucial to achieve a healthy nutritional status.

Malaysian Journal of Nutrition.2011;17(2):229-236.

Introduction: The present study describes a randomised controlled trial (RCT) based on a novel, generalisable intervention for childhood obesity, comparing the intervention with a no-treatment control group. Method: The Malaysian Childhood Obesity Treatment Trial (MASCOT) was a single-blind RCT of a dietetic treatment for childhood obesity in children of primary school age (7 to 11 years old) in Kuala Lumpur, Malaysia. The MASCOT comprising eight sessions, of an 8-hour family-centred group treatment programme is described, based on behavioural change techniques. The study sample was characterised by BMI zscore, health related quality of life reported by participants and their parents (PedsQL questionnaire), objectively measured habitual physical activity and sedentary behaviour (Actigraph accelerometry) Results: The MASCOT sample of 107 children was characterised by a low quality of life, mean total score on PedsQL 67.7 (4.5) as reported by the children, and 66.0 (16.4) as reported by their parents. The children spent, on average, 89% of their waking day on sedentary activity, and 1% of the day in moderate-vigorous intensity physical activity, equivalent to only around 8 minutes/day. Conclusion: Obese children in the MASCOT study had an impaired quality of life, high levels of sedentary behaviour and very low levels of physical activity.

Chocolate: Food for Moods

Wong SY ; Lua PL

Malaysian Journal of Nutrition.2011;17(2):259-269.

Introduction: Chocolate is a popular food and its consumption has long been associated with enjoyment and pleasure. The effect of chocolate on mood too has long been recognised. Chocolate is thought to have interactions with neurotransmitters which contribute to mood modulation and appetite regulation. However, the evidence in chocolate and mood studies remains highly controversial. As more is known about the influence of chocolate on mood, the reasons for these effects appear increasingly complex and inter-related. Methods: We reviewed chocolate’s properties and the principal hypotheses addressing its mood altering propensities. Results: The relationship between chocolate and mood are highly complex, combining psychopharmacological components, nutritional and sensory characteristics of the food. Individual and situational differences on chocolate consumption may also exert influence on mood and the mixed results in previous research indicate that the direction of the association remains unclear. Conclusion: The association between chocolate consumption and emotions warrants further multi-prong investigations to substantiate chocolate’s mood alterating propensity.

Loy SL ; Marhazlina M ; Nor Azwany Y ; Hamid Jan JM

Malaysian Journal of Nutrition.2011;17(1):1-18.

Introduction: This study aimed to develop and examine the validity and reproducibility of a semi-quantitative food frequency questionnaire (FFQ) among Malay pregnant women in Kelantan, Malaysia. Methods: A total of 177 Malay pregnant women participated in the validation study while 85 of them participated in the reproducibility study which was carried out in the antenatal clinic of Universiti Sains Malaysia Hospital. The newly developed FFQ was validated against two 24-hour dietary recalls (DR). The FFQ was repeated 20 to 28 days apart. Results: Results showed that the FFQ moderately over estimated the nutrient and food intakes compared to the DR. Spearman correlation coefficients for nutrients ranged from 0.24 (fat) to 0.61 (calcium) and for foods, ranged from 0.13 (organ meats, onion and garlic) to 0.57 (malt drink). For nutrients, 72 to 85% of women were classified into the correct quartiles from the FFQ and the DR while for foods, 67 to 85% of women were classified correctly. Bland-Altman plot showed relatively good agreement between these two dietary methods. The intra-class correlation (ICC) was used to estimate reproducibility. It ranged from 0.75 (vitamin C) to 0.94 (phosphorus) for nutrients while it ranged from 0.73 (confectionary) to 0.96 (coffee) for foods. Conclusion: On average, at least 90% of pregnant women were correctly classified into the quartiles for nutrients and foods from the two sets of the FFQ. The FFQ presented acceptable reproducibility and appears to be a valid tool for categorising pregnant women according to dietary intake.
