Introduction: Poor appetite is prevalent among older adults and may negatively impact on their overall health. This is especially true for institutionalised residents. Despite this, there is a paucity of research on appetite and its associated factors among institutionalised residents, which signified the present study. Methods: A cross-sectional study was conducted among elderly residents at long-term care facilities in the state of Selangor, Malaysia to ascertain their appetite status and its associated factors. Results: A total of 97 residents with mean age of 74.2±8.4 years old were recruited. They comprised 61.9% females and 38.1% males. More than 50% had poor appetite with early satiety. There were 63.0%, 82.4%, and 94.8% who had poor oral health, poor sleep quality, and depression, respectively. Ethnicity (OR=2.73; 95% CI=1.00-7.44; p=0.049) was the only factor that predicted poor appetite among older adults in long-term care facilities, with Malay residents having poorer appetite than their Chinese and Indian counterparts. Conclusion: The prevalence of poor appetite was high among residents staying at long-term care facilities in Selangor, Malaysia, especially among Malays. This issue deserves further studies to identify the specific underlying factors contributing to poor appetite among older adults from different ethnicities. Acknowledging the high prevalence of poor appetite among older adults and its possible unfavourable outcomes, appropriate nutrition interventions are therefore needed to address this issue among institutionalised elderly.

Introduction: To identify the growth patterns of young children during the first two years of life according to gestational age, birth weight, and growth status at 24 months of age. Methods: This was a retrospective cohort study of 4,570 young children in Selangor. Data were extracted from children’s health records in government health clinics. Growth data were analysed using the Anthro Plus software that utilises the World Health Organization growth standards. Results: Generally, wasting prevalence was the highest at birth and 24 months, but stunting was more predominant from 1 to 21 months. Weight-for-age z-scores (WAZ), lengthfor-age z-scores (LAZ), and weight-for-length z-scores (WLZ) from birth to 24 months were within -3.00 to 0.00 standard deviation (SD) for pre-term low birth weight children, –1.50 to 0.00 SD for pre-term normal birth weight children, and –2.50 to 0.50 SD for full-term low birth weight children. While WAZ, LAZ, and WLZ from birth to 24 months for underweight/stunted/wasted children were within –2.50 to 0.50 SD, the values for overweight/obese (OV/OB) children were within –1.00 to 2.00 SD. For normal children, WAZ, LAZ, and WLZ exhibited comparable trends, with values within –1.00 to 0.00 SD from birth to 24 months. Conclusion: While stunting and wasting persisted as the most common forms of malnutrition in this sample of young children, the prevalence of OV/OB increased by 24 months. Interventions to promote child growth should focus not only on the prevention of undernutrition, but also on OV/OB.

Introduction: Ability to taste 6-n-propylthiouracil (PROP) predicts both taste sensitivity and food preferences, with PROP tasters being more sensitive to sweet taste in foods, which may lead to less intake of sugary foods. However, when obesity progresses, the individual’s sense of taste and eating patterns may change. The aim of this study was to evaluate if PROP taster status affected habitual sweet food consumption and nutritional intake in obese and non-obese people. Methods: A total of 88 obese and 92 non-obese Malay male and female participants aged 20-45 years were classified into PROP non-tasters, medium tasters, or supertasters by using PROP filter paper screening procedure. Sweet food consumption was assessed using food frequency questionnaire (FFQ), while dietary intake was measured by using 3-day food diary. Data were analysed using General Linear Model (GLM) Analysis of Covariance (ANCOVA) to compare for differences and associations among variables. Results: Overall, there was no significant association between body mass index groups and PROP taster status (p>0.05). No significant differences were found on any habitual sweet food intake and dietary intake according to PROP taster status in both obese and non-obese participants (p>0.05). However, there was a significant difference (p<0.05) in fruit intake according to PROP taster status among obese participants. Conclusion: The findings suggest that PROP taster status does not play a role in nutrient intakes among obese and non-obese individuals.

BACKGROUND/OBJECTIVES: Low early pregnancy serum 25-hydroxy vitamin D (25[OH]D) levels can increase gestational diabetes mellitus (GDM) risk, although inconsistent findings related to that association have been reported. This study examined the association of serum vitamin D with GDM and the possible influencers on this association. SUBJECTS/METHODS: This study included 259 pregnant women within the Seremban Cohort Study (SECOST). Blood samples at < 14 weeks of gestation were drawn to determine serum 25(OH)D levels. GDM diagnosis was made at 24 to 32 weeks of gestation using a standard procedure. Association between serum vitamin D and GDM was tested using binary logistic regression. RESULTS: Nearly all women (90%) had mild (68.3%) or severe (32.2%) vitamin D deficiency (VDD). Non-GDM women with mild VDD had a significantly higher mean vitamin D intake than GDM women with mild VDD (t = 2.04, p < 0.05). Women with higher early pregnancy serum vitamin D levels had a greater risk of GDM. However, this significant association was only identified among those with a family history of type 2 diabetes mellitus (T2DM) and in women with a body mass index indicating overweight or obese status. CONCLUSIONS The high prevalence of VDD in this sample of pregnant women underscores the need for effective preventive public health strategies. Further investigation of this unexpected association between serum vitamin D level and GDM risk in predominantly VDD pregnant women and the potential effects of adiposity and family history of T2DM on that association is warranted.

Introduction: This cohort aimed to determine glycemia distribution of pregnant women and maternal glycemia categories and its correlation with adverse pregnancy outcomes among Malaysian women. Methods: A retrospective cohort study of normal glycemia pregnant women. Binary logistic regression was used to examine the associations between maternal glycemia categories and adverse outcomes. Results: Women with elevated fasting plasma glucose (FPG) were at lower risk of having SGA infants (aORFPG 4= 0.64, 95% CI= 0.47 – 0.85; aORFPG 6= 0.68, 95% CI= 0.43–0.98; aORFPG 7= 0.64, 95% CI= 0.42–0.96) than those women in category 1. Women in the higher 2-hour plasma glucose (2hPG) category had a nearly two-fold risk of having LBW and LGA infants. Hyperglycemia less severe than gestational diabetes mellitus (GDM) was associated with LGA (aOR= 1.22, 95% CI= 1.07 – 1.88) and caesarean delivery (aOR= 1.80, 95% CI= 1.20 – 2.69), in the meanwhile GDM was associated with caesarean delivery (aOR= 1.33, 95% CI= 1.02 –1.79). Conclusion: Cut-off points for FPG and 2hPG that relate to adverse pregnancy outcomes started at 4.9 – 5.0 mmol/l and 7.5 – 7.7 mmol/l. These cut-off points were lower than the current recommended criteria of Clinical Practice Guideline (CPG) of Malaysia for GDM diagnosis. Large-scale studies are required to identify the optimal GDM cut-off.

Introduction: Vitamin D deficiency (VDD) is associated with adverse health outcomes in pregnancy and newborns. This study aims to determine the Vitamin D status among pregnant Malaysian women and its associations with specific maternal & pregnancy characteristics. Methods: This study utilised cross-sectional data from a prospective cohort study of pregnant women in Seremban district in which 259 pregnant women had available vitamin D data. Blood samples were taken <14th week of gestation. Serum 25-hydroxy Vitamin D [25(OH)D] levels were analysed using chemiluminescent microparticle immunoassay (CMIA) technology on the ARCHITECT iSystem and categorised using the Institute of Medicine (IOM) 2011 cutoffs. A set of pre-tested interviewer-administered questionnaire was used to obtain information on socio-demographics, obstetrics, and anthropometry. Results: Mean serum 25(OH)D was 32.83±11.37nmol/L. The prevalence of severe and mild VDD was 23.2% (n=60) and 68.3% (n=177), respectively. About 8.5% (n=22) of pregnant women were vitamin D insufficient and none had sufficient serum 25(OH)D (>75nmol/L). Early pregnancy body mass index (AOR=2.95, 95% CI=1.03-8.47), working status (AOR=3.17, 95% CI=1.06–9.50) and gravidity (AOR=0.68, 95% CI=0.48–0.98) were significantly associated with VDD. Conclusion: The present study showed a high prevalence of VDD among pregnant women in Malaysia, especially among those who were overweight or obese, working in indoor environment and primigravida.

Introduction: This cross-sectional study aimed to investigate relationships between diet quality assessed by Malaysian Healthy Eating Index (HEI) and cardiometabolic risk factors in adolescents aged 13 years. Methods: 336 adolescents from various public secondary schools provided information on sociodemography and their anthropometric measurements including height (cm), weight (kg) and waist circumference (cm) were measured. Body mass index (BMI) was estimated thereafter. Dietary intakes assessed using a validated adolescent food frequency questionnaire (FFQ) was used to estimate Malaysian HEI. Biomarker parameters including lipid profile, fasting glucose, insulin and insulin resistance were also assessed. Associations of diet quality indicators to cardiometabolic risk factors were examined using regression models. Results: The overall diet quality of the adolescents was rather poor (49%), with a greater percentage of males were found to have low dietary quality score compared to females (56% vs. 39%; p<0.05). While males were more obese, a higher number of females (46.7%) were found to have at least one risk factors for cardiometabolic health compared to males (37.7%). After adjusting for covariates, no significant associations were observed among adolescents in the lowest quartile compared to those in the highest quartile of HEI score for obesity and abdominal obesity, as well as other cardiometabolic risk factors, in both males and females. Conclusion: Despite of poor dietary quality, no significant associations were observed between dietary quality assessed by Malaysia HEI and cardiometabolic risk factors in adolescents. Prospective studies are needed to establish a causal link between dietary patterns and cardiometabolic risk factors during adolescence.

Introduction: A growing evidence supported that variation of sweet taste perception, mediated by TAS1Rs gene variants could lead to excess sweetened food and beverages intake and also obesity. However, obesity development may also alter individuals' taste sensitivity and perception. Thus, it is best to further investigate whether or not the individuals' sweet taste sensitivity and acceptance are associated with variation in TAS1R2 gene and Body Mass Index (BMI) status. Methods: This comparison cross sectional study comprised of 88 obese and 92 non-obese subjects aged 20-45. All the subjects were genotyped for TAS1R2 gene variant at rs12033832 using polymerase chain reaction – restriction fragment length polymorphism (PCR-RFLP). Suprathreshold sensitivity for sweet taste was assessed using general Labeled Magnitude Scales. Intensity rating and hedonic test were carried out on 2 food samples (tea drink and rose flavoured agar) to examine subject's intensity rating and liking at different sugar contents. Results: Our results showed that rs12033832 of TAS1R2 gene is associated with sweet taste perception among obese and non-obese subjects. No interaction effect between BMI status and TAS1R2 gene variant (rs12022832) was found on sweet taste measures. Overall, non-obese subjects with AA genotype on rs12033832 had the highest sweet taste sensitivity and dislike high sugar content products the most. The effect was reverse among the obese subjects with GG homozygous. Conclusion: These findings suggest that TAS1R2 gene variation plays an important role in sweet taste perception among individuals and may have nutritional implications and obesity.

Introduction: The prevalence of child undernutrition and micronutrient deficiencies are higher in the Orang Asli (OA) than the general Malaysian population. The World Health Organization recommends the use of multiple micronutrient supplement (MMS) that is a blend of micronutrients in powder form that can be sprinkled onto foods for home fortification to prevent undernutrition among children. This pilot study aimed to assess the feasibility of using MMS among OA children. Methods: A total of 25 OA children (14 boys and 11 girls) aged 6-31 months (mean±SD = 15.7±7.2 months) in Negeri Sembilan were given three sachets of MMS weekly for 5 weeks. Caregivers were instructed to add MMS to three types of food from the same food group per week varying with a different food group weekly. Written instruction for using MMS in simple language was given prior to the supplementation. Caregivers were interviewed for information on socio-demographics, compliance, acceptance, preference and adverse effect of MMS. Results: A high level of compliance was observed (85%). All caregivers reported that the instructions for use were easy to read. No noticeable changes to the foods mixed with MMS were observed and no adverse effects were reported. Conclusion: This study demonstrated feasibility of the use of MMS for future trials among OA children. The easy to read information that comes with the MMS, frequent monitoring of MMS use and support to caregivers were required to ensure compliance. Cultural feeding practices and financial constraints may limit the types of food that can be mixed with MMS.

Introduction: Obesity and excess weight gain in adults are linked to an increased risk of cardiometabolic abnormalities. The changing lifestyle experienced by the Orang Asli predisposes the population to the risk of obesity and non-communicable diseases. This study aimed to describe the prevalence of overweight and obesity as well as body-weight change over a period of four years among Orang Asli adults. Methods: Data were collected from Orang Asli adults aged ≥18 years, who were enrolled in the 2011-2012 and 2015-2016 surveys, and who were residing within the Krau Wildlife Reserve. Weight and height of the adults (N2011-2012=828; N2015- 2016=662) were measured at both time points. Follow-up data were available for 378 adults (male:113; female:265). Results: The prevalence of overweight and obesity were 18.8% and 7.4% in 2011-2012 and 26.1% and 9.5% in 2015-2016. In the follow-up group, significant differences in body weight and body mass index (BMI) were observed in men and women, respectively. More than one-third (35.5%) of the adults had weight gain of more than 5.0%. The increasing percentage of body weight change was associated with being female, younger age, more years of schooling and reduced household income. Conclusion: Obesity is a growing health problem in the Orang Asli adult population. Weight gain was associated with socioeconomic indicators and it was more prominent in women. Effective strategies are needed to address the increasing prevalence of overweight and obesity in this population to further reduce adverse health outcomes.
