Introduction: Malaysian adults consume excessive amounts of salt daily, which could lead to hypertension. Understanding knowledge, attitudes, and practices (KAP) surrounding salt intake is crucial for designing effective interventions to reduce excessive consumption and its associated health risks. Therefore, this study aimed to adapt an existing salt intake-related KAP questionnaire that was previously employed in a local population-based survey and to validate and test its reliability. Methods: This cross-sectional study comprised two phases: (1) adaptation, content validation (CV), and face validation (FV); (2) pilot testing and reliability testing. CV and FV involved a total of seven experts and ten Malaysian adults from the Klang Valley, respectively. Pilot testing involved 139 Malaysian adults to determine the questionnaire’s reliability. Content validity index (CVI) and Face validity index (FVI) values were calculated to analyse CV and FV. Reliability of each domain was analysed by obtaining Cronbach’s alpha (α) values. Results: A self-administered questionnaire comprising six items each for knowledge, attitude, and practice was developed. The questionnaire demonstrated acceptable item-level CVI (I-CVI) and item-level FVI (I-FVI) values of at least 0.83, indicating that the items were relevant, clear, non-ambiguous, and simple. Reliability test showed acceptable α values of at least 0.70 for each domain, suggesting that the questionnaire was reliable. Conclusion: This tool could be considered valid and reliable for assessing the level of KAP towards salt intake among adults in Malaysia.

Introduction: With the new set of 2021 infant and young child feeding (IYCF) indicators released by WHO and UNICEF, there is a need for its validation in the Philippine setting. The study evaluated the validity of cut-off points used for minimum dietary diversity and minimum feeding frequency in terms of micronutrient and energy intake adequacy, respectively, and minimum acceptable diet (MAD) in relation to anthropometric status. Methods: The study covered 8360 infants and young children aged 6-23.9 months with complete information on IYCF, anthropometric measurements, maternal information, and household characteristics from the 2018-2019 Expanded National Nutrition Survey (ENNS). Bivariate and correlation analyses using STATA version 15 (Corp LLC, Texas, USA 2017) were performed to determine the association of specific IYCF indicators: dietary diversity and feeding frequency with nutrient and energy intake adequacy, and MAD with anthropometric status. Sensitivity and specificity analyses were performed to evaluate the accuracy of dietary diversity score (DDS) and feeding frequency in identifying children with adequate nutrient and energy intakes, respectively. Results: Significant associations were found between DDS and micronutrient adequacy, and between feeding frequency and energy intake adequacy, regardless of breastfeeding status. A DDS of 5 and 6 and feeding frequency of 4-5 and 8 maximised sensitivity and specificity in identifying breastfed and non-breastfed children meeting 100% nutrient and energy adequacy, respectively. Conclusion: The selected 2021 complementary feeding indicators are practical guidelines to reflect dietary adequacy, but may not capture the entire process related to nutritional outcomes, especially stunting.

Introduction: Food security can be defined as the availability of and accessibility to food, acquired in an acceptable means at any given time and place in a way that could maintain health and wellbeing. One critical dimension of food security is continued access to adequate food. To measure this dimension, the Food and Agriculture Organization (FAO) developed the latest measurement tool, namely the Food Insecurity Experience Scale (FIES), the first instrument to measure people who experience food insecurity globally. This study aimed to validate the construct validity and reliability of the Malay version of FIES (M-FIES) for Malaysians. Methods: This cross-sectional study was conducted among 145 households in Kuantan, Pahang. Rasch analysis was used to analyse the construct validity of FIES. Results: FIES met the Rasch model assumptions with all items having an infit value of between 0.7- 1.3 and an outfit value of <2.0. The item and person reliability were 0.97 and 0.71, respectively; while the item and person separation were 5.59 and 1.58, respectively. The FIES item severity indicated that the items “few food”, “healthy”, “skipped”, “ate less”, and “runout” were disordered. Conclusion: The M-FIES is a valid and reliable measurement tool for the food insecurity situation among households based on its construct validity assessed using the Rasch model. Furthermore, the severity of item in M-FIES was different in terms of order from the original FIES, suggesting that the same items may be interpreted differently due to cultural or societal differences.

Introduction: Resistant starch has elicited new possibilities around the globe due to its plausible health benefits and functional properties. This research aimed to evaluate the effect of processing on the resistant starch content in selected Indian rice varieties and its effect on postprandial blood glucose levels. Methods: Two Indian rice varieties (Sona Masuri and Mogra) were evaluated for resistant starch in raw form, after boiling, steaming, and refrigeration. Thereafter, the increment in resistance starch content by different processing methods was validated by oral glucose tolerance test (OGTT) on ten healthy participants. Results: Among the two rice varieties, raw Sona Masuri had a higher resistance starch content (10.86%). After processing, resistant starch was observed to be high in steamed Mogra variety (3.52%). In the boiling process, Sona Masuri developed a higher resistant starch content (2.44%) as compared to Mogra variety (1.05%). The assessment done after refrigeration revealed a slight increase in resistant starch content in both rice varieties. Mogra variety had higher resistant starch (3.68%) than the other rice variety (2.56%) after refrigeration. Validation of increase in resistant starch content and its effect on blood glucose responses done through OGTT revealed that Mogra rice (test food) did not cause a swift spike in blood glucose level compared to glucose (reference food). Differences in blood glucose responses by test and reference food at 0, 30, 60, 90, and 120 minutes were statistically significant. Conclusion: Steamed and refrigerated Mogra rice did not cause significant increase in blood glucose.

Introduction: Nutritional requirements of pregnant women differ considerably from those of non-pregnant women. Nutritional status during pregnancy is critical to maintain health, including oral health, and to promote growth and development of the baby. This study assessed dietary pattern, nutrient intake, and oral symptoms among pregnant women. Methods: Seventy-one women with singleton pregnancy attending a public healthcare centre in Malaysia participated in this cross-sectional study. Dietary pattern and nutrient intake of the women were assessed using food frequency questionnaire and 3-day 24-hour diet recall, respectively. Information on sociodemographic and obstetric profiles, and oral symptoms were obtained from self-administered questionnaire. Results: White rice, chicken, green leafy vegetables, granulated sugar, and salt were foods most consumed. Intakes of iron, folate, vitamin C, vitamin D, calcium, iodine, zinc, and fluoride for most respondents were below Recommended Nutrient Intake (RNI). Cavitated tooth (46.5%), bleeding gums (35.2%), pain upon eating and drinking (23.9%), and bad breath (23.9%) were common oral symptoms reported. Significant association was found between complaint of brown, yellow, and white spots on tooth surface with vitamin A intake, and between complaint of bleeding gums with zinc intake. Conclusion: Intake of most nutrients by most respondents in this study was below the RNI. Oral symptoms were common and a few were associated with nutrient intakes.
导言：孕妇对营养的需求与非孕妇有很大不同。怀孕期间的营养状况对维持健康（包括口腔健康）和促进婴儿的生长发育至关重要。本研究对孕妇的饮食模式、营养摄入量和口腔症状进行了评估。研究方法71名在马来西亚一家公共医疗保健中心就诊的单胎妊娠妇女参与了这项横断面研究。研究人员分别采用食物频率问卷和 3 天 24 小时饮食回忆法对孕妇的饮食模式和营养摄入量进行了评估。有关社会人口学和产科概况以及口腔症状的信息来自自填问卷。结果白米饭、鸡肉、绿叶蔬菜、砂糖和盐是摄入最多的食物。大多数受访者的铁、叶酸、维生素 C、维生素 D、钙、碘、锌和氟的摄入量低于建议营养摄入量。龋齿（46.5%）、牙龈出血（35.2%）、饮食疼痛（23.9%）和口臭（23.9%）是常见的口腔症状。发现牙齿表面出现褐色、黄色和白色斑点与维生素 A 的摄入量有显著关系，牙龈出血与锌的摄入量有显著关系。结论本研究中大多数受访者的营养素摄入量低于营养参考值。口腔症状很常见，少数症状与营养素摄入量有关。

Introduction: Food and fitness levels are key factors required to maintain functional life. Hence, nutrition education is crucial in spreading awareness among Sports Science students. There is a paucity of plant-based nutrition knowledge and plantbased culinary skills for fitness locally. Therefore, this study aimed to develop a valid Plant-Based Culinary Nutrition Model (PBCNM) with nutrition knowledge and basic culinary skills to improve fitness among Sports Science students. Methods: This exploratory sequential mixed method study consisted of 2 phases. In Phase 1, a three-round modified Delphi method was conducted with 13 experts to generate a questionnaire that was validated. Lawshe worksheet determined the content validity ratio (CVR) for an item. Content validity index (CVI) for each section and the overall instrument was calculated. In Phase 2, quantitative data collection and analysis addressed the research questions and research gaps leading to model development. A total of 271 undergraduate Sports Science students at higher learning institutions were recruited as respondents. Results: In Phase 1, CVR of the overall survey was 1.0 and CVI was 0.834. Subsequently, the questionnaire was pilot tested for reliability and a Cronbach’s alpha score of 0.836 was obtained for the overall questionnaire. In Phase 2, the respondents’ mean and standard deviation score for the model’s components and needs was 4.21±0.73 for items 1-15. The integration of experts’ perspectives on the need of PBCNM for fitness and feedback from respondents resulted in the development of PBCNM. Conclusion: This study highlighted PBCNM as a helpful guideline for better fitness management.

Introduction: Vitamin D levels are known to be related to prevalence of allergy and infection in children. However, vitamin D levels in infants’ umbilical cord blood need to be investigated. Therefore, this study aimed to determine association between 25-hydroxyvitamin D [25(OH)D] levels and incidence of allergy and infection in children. Methods: A longitudinal study involving 38 full-term newborns was conducted. Serum 25(OH)D levels in infants’ umbilical cord and venous blood were measured at birth and six months, respectively. 25(OH)D levels were classified as insufficient (<20 ng/mL) and sufficient (>20 ng/mL). Parents filled out questionnaires about their children’s allergy and infection symptoms. Paired t-test was performed to compare the 25(OH)D levels at birth and at six months. Chisquared test was conducted to determine relationship between 25(OH)D levels and incidence of infection and allergy in children. Results: 25(OH)D levels in venous blood of 6-month-old infants were significantly higher than in umbilical cord blood (50.44±13.59 ng/mL vs. 20.70±6.60 ng/mL, p<0.001). In addition, 25(OH)D level insufficiency in umbilical cord blood was associated with infection (p<0.05). However, there was no incidence of allergy, and exclusive breastfeeding and sun exposure were not associated with vitamin D levels in 6-month-old infants. Conclusion: We conclude that 25(OH)D level insufficiency in umbilical cord blood was associated with incidence of infection in the first six months of life.
导言：众所周知，维生素 D 水平与儿童过敏症和感染的发病率有关。然而，婴儿脐带血中的维生素 D 水平仍有待研究。因此，本研究旨在确定 25-羟基维生素 D [25(OH)D] 水平与儿童过敏和感染发病率之间的关系。研究方法对 38 名足月新生儿进行了纵向研究。分别在婴儿出生时和六个月时测量其脐带血和静脉血中的血清 25(OH)D 水平。25（OH）D水平不足（20纳克/毫升）被归为不足。家长填写了有关孩子过敏和感染症状的问卷。采用配对t检验比较出生时和6个月时的25（OH）D水平。用奇平方检验确定 25（OH）D 水平与儿童感染和过敏发病率之间的关系。结果：6个月大婴儿静脉血中的25（OH）D水平明显高于脐带血（50.44±13.59 ng/mL vs. 20.70±6.60 ng/mL，P<0.001）。此外，脐带血中 25(OH)D 含量不足与感染有关（P<0.05）。然而，6 个月大婴儿中没有过敏发生率，纯母乳喂养和日光照射与维生素 D 水平无关。结论我们得出的结论是，脐带血中 25(OH)D 含量不足与出生后 6 个月内的感染率有关。

Introduction: High-calorie diets, particularly the quality of dietary fats, are regarded as an independent risk factor for developing obesity, hyperlipidaemia, and liver diseases. The present study examined the impact of rice bran oil (RBO) on organ-specific fat deposition, lipid profile, and liver function enzymes in Long Evans rats. Methods: Long Evans rats (n=24) were fed for six weeks with a controlled high-fat diet (HFD) to induce hyperlipidaemia and abnormal liver function. Rats were then divided into two groups: one group continued feeding on HFD, and the other group was fed with a RBO diet, replacing the fat source. After six weeks of feeding, six rats from each group were sacrificed and required analytical tests were performed. The remaining obese rats (n=12) were divided into continued HFD and RBO diet, and after sacrificing, essential analytical tests were done. Results: RBO feeding to hyperlipidaemic rats for six weeks significantly reduced brown adipose tissue, abdominal adipose tissue, epididymal adipose tissue, and liver fat compared to continuing HFD group (p<0.05). Similarly, serum levels of total cholesterol, triacylglycerides, and low-density lipoprotein cholesterol were all decreased, whereas high-density lipoprotein cholesterol increased in response to RBO compared to HFD (p<0.05). Additionally, rats fed with RBO showed reduced alanine aminotransferase, aspartate aminotransferase, and gamma-glutamyl transferase levels when compared with continuing HFD-fed rats (p<0.05). Conclusion: These findings suggest that RBO supports the reduction of fat storage from major fat depots, controls lipid profile, and restores healthy liver functions in rats.
导言：高热量饮食，尤其是膳食脂肪的质量，被认为是导致肥胖、高脂血症和肝脏疾病的独立风险因素。本研究探讨了米糠油（RBO）对 Long Evans 大鼠器官特异性脂肪沉积、脂质概况和肝功能酶的影响。研究方法用控制性高脂饮食（HFD）喂养 Long Evans 大鼠（n=24）六周，以诱发高脂血症和肝功能异常。然后将大鼠分为两组：一组继续喂食高脂饮食，另一组喂食 RBO 食物，以替代脂肪来源。喂食六周后，每组牺牲六只大鼠，并进行必要的分析测试。剩下的肥胖大鼠（12 只）分为继续喂食高脂饮食和 RBO 饮食两组，牺牲后进行必要的分析测试。结果高脂血症大鼠饲喂 RBO 六周后，棕色脂肪组织、腹部脂肪组织、附睾脂肪组织和肝脏脂肪均比持续高脂饮食组明显减少（P<0.05）。同样，与高脂饮食组相比，RBO 组大鼠血清总胆固醇、三酰甘油和低密度脂蛋白胆固醇水平均下降，而高密度脂蛋白胆固醇水平上升（p<0.05）。此外，与继续喂食高纤维食物的大鼠相比，喂食 RBO 的大鼠丙氨酸氨基转移酶、天冬氨酸氨基转移酶和γ-谷氨酰转移酶水平降低（p<0.05）。结论这些研究结果表明，RBO 有助于减少大鼠主要脂肪库的脂肪储存、控制血脂状况并恢复健康的肝功能。

The present study examined the impact of rice bran oil (RBO) on organ-specific fat deposition, lipid profile, and liver function enzymes in Long Evans rats. Methods: Long Evans rats (n=24) were fed for six weeks with a controlled high-fat diet (HFD) to induce hyperlipidaemia and abnormal liver function. Rats were then divided into two groups: one group continued feeding on HFD, and the other group was fed with a RBO diet, replacing the fat source. After six weeks of feeding, six rats from each group were sacrificed and required analytical tests were performed. The remaining obese rats (n=12) were divided into continued HFD and RBO diet, and after sacrificing, essential analytical tests were done. Results: RBO feeding to hyperlipidaemic rats for six weeks significantly reduced brown adipose tissue, abdominal adipose tissue, epididymal adipose tissue, and liver fat compared to continuing HFD group (p<0.05).

Introduction: Food insecurity is a public health concern that may lead to malnutrition in children. The purpose of this study was to determine the relationship between demographic characteristics and food security level with nutritional status among children from food-insecure households in Simunjan District, Sarawak. Methods: This study involved a total of 171 mother-and-child pairs from two Maternal and Child Health Clinics (Simunjan and Gedong) using non-probability convenience sampling technique. Food insecurity status was determined using Radimer/Cornell Hunger Food Insecurity Instrument, while child’s weight and height were measured following standard procedures. Chi-squared test of independence and binary logistic regression were used during data analysis. Results: The prevalences for household food insecurity, individual food insecurity, and child hunger were 70.8%, 15.2%, and 14.0%, respectively. The main nutritional problems for children aged 24–59 months were underweight (17.9%) and stunting (17.9%), while for children aged 60–144 months were overweight and obesity (27.5%). Children of mothers over 34 years old (AOR=2.367; 95% CI: 1.085, 5.164), and those aged 60–144 months (AOR=3.619; 95% CI: 1.521, 8.613) had increased odds of being overweight or obese. Meanwhile, children of working mothers (AOR=6.526; 95% CI: 1.108, 38.449) were more likely to have a thinness problem than children of unemployed mothers. However, no association was found between the severity of food insecurity with children’s nutritional status. Conclusion: Malnutrition in children remains a public health concern in Simunjan District, and it is linked to mother’s age and employment status. An intervention programme is required to ameliorate the situation.

Introduction: Biomass microalgae functional materials, such as drugs and food supplements, have recently received much attention. Euglena sp. is a particularly appealing microalgae because of its simplicity of culture and capacity to produce a wide range of bioactive compounds. Moreover, it is one of the few microorganisms that produces carbohydrate, lipid, protein, ß-1,3-glucans, antioxidants, phytotoxins, wax esters, and polyunsaturated fatty acids that can be used to make nutraceuticals, pharmaceuticals, and cosmeceuticals. However, the potential utilisation of Euglena sp. for production of food supplements has been exploited only on a limited basis. Methods: This study was modified by adding protocatechuic acid and photoperiodism for 12:12; 14:10; 16:8; and full dark to affect the metabolite content of Euglena sp. Results: Results showed that the photoperiod had significant effect on lipid, chlorophyll-a, and carotenoid levels in the control treatment, with the highest levels as follows: 0.52±0.03 g/L, 1.20±0.01 x10-2 g/L, 0.30±0.02 x10-2 g/L; while the others were not significantly affected by the treatment, with the highest protein content at full dark 3.10±0.2 x10-2 g/L; chlorophyll-b at photoperiod 14:10 0.70±0.03 x10-2 g/L; paramylon at photoperiod 12:12 1.90±0.02 x10-1 g/L. The highest carbohydrates were found in control, with a level of 1.20±0.02 g/L. Conclusion: Photoperiodism is recommended to enhance productivity of protein, paramylon, and chlorophyll-b, while full light is recommended to enhance carbohydrate, lipid, chlorophyll-a, and carotenoid production in Euglena sp. to improve the quality of food nutrition.
