Students nowadays in Malaysia and globally, prefer to consume caffeinated energy drink to stay up late to finish their daily task especially during exams or finishing their coursework. Despite the rising trends and aggressive marketing strategies aimed toward college students, there has been little research done on college students’ intake of caffeinated energy drinks and their impact on sleep quality such as the daytime sleepiness. Bad sleep quality is also significantly found more commonly in those with psychological distress which will then consequently affect students’ academic performances. This research studies about universities student pattern of consumption of caffeinated energy drink and how it affects their level of daytime sleepiness and level of psychological distress. In this research, The Epworth Sleepiness Scale (ESS) was used to evaluate general level of daytime sleepiness and the capability to stay alert and awake during crucial moments of the day. While the level of psychological distress were measured using the 12-item General Health Questionnaire (GHQ-12), a self-administered screening instrument designed to detect current diagnosable mental disturbances and disorders. Research findings showed that there are generally higher usage of caffeinated energy drink in male, between 20 to 22 years old and active in any physical activity, among participants whom does not consume caffeinated energy drink, majority score CGPA between 3.00 to 3.50. Also, there are significance between the psychological distress and consumption of caffeinated energy drink, 86.3% whom does not consume caffeinated energy drink does not have psychological distress and between daytime sleepiness and psychological distress, about 71.8% daytime sleepers have psychological distress (p
This study targeted two candidate genes from the best known regulator of blood pressure; the rennin angiotensin system; the ACE gene I/D polymorphism and the angiotensinogen M235T polymorphism. The study aimed to determine the genotypes trend between two different populations; the primary hypertensive patients, and the normal populations. 126 subjects were involved in this study (86 primary hypertensive patients and 40 normal individuals). All demographic factors were considered and analyzed. Insertion/deletion polymorphisms of the ACE gene were determined by an assay based on the polymerase chain reaction (PCR). Polymorphism analysis using PCR-RFLP procedure was used to identify the missense mutation M235T of the AGT gene. All significant data was collected using standardized case report form. The association of the different genotypes and the subjects’ condition was analyzed using the chi squared and odds ratio analyses. In the pooled analysis of both groups, it was shown that the polymorphisms in these genes were significantly associated with the incidence of primary hypertension, p<0.05. Results also showed that the D allele of the ACE gene may be associated with increased risk of primary hypertension (p<0.05, O.R: 3.0 [C.I: 1.25 – 5.35]). The angiotensinogen M235T polymorphism also showed a significant result; the T allele is associated with increased risk of primary hypertension (p<0.05, O.R: 2.56[C.I: 1.55 – 5.28]). This knowledge of the candidate genes of rennin angiotensin system has rendered it possible to show that gene polymorphism in symphony leads to the individual risk of primary hypertension.

Introduction: Data on water and sugar sweetened beverages (SSB) intake
among young adults in Malaysia is sparse. This study aimed at measuring the
intake of plain water and SSB among undergraduate students in a Malaysian
university and examine its association with body mass index (BMI). Methods:
A total of 376 undergraduate students aged 18-30 years were recruited. A selfadministered questionnaire was used to determine the SSB consumption pattern.
The questionnaire consisted of five sections that included the background of the
participants, knowledge about SSB, SSB preferences, frequency and portion size.
Results: 23.9% of subjects in this study were overweight. Almost all of the subjects
took outside food (93.1%) and drink (74.2%). The highest daily consumption was
plain water (92.3%), with a majority drinking more than two cups at each intake.
Caffeinated drinks (coffee or tea) were the most popular SSB among the students
(18.4%). Most students (79.7%) did not consume SSB on a daily basis. A significant
association was found between the proportion of plain water consumption and BMI
(p
Introduction:Orang Asli (OA) in Malaysia is considered vulnerable to social, economic and legal abuse. The in-crease in prevalence of Non-Communicable Diseases (NCDs) among OA was reported due to their lifestyle changes. Our study aimed to determine the level of knowledge on NCDs among OA community and its’ association with demographic factors. Methods: A cross-sectional study by face-to-face interview was conducted among consented adult OA in Jelebu, Negeri Sembilan using a validated questionnaire. Their knowledge on risk factors, complica-tions and treatment of cardiovascular diseases, diabetes mellitus, and chronic obstructive pulmonary diseases was asked. Respective thresholds and ranges for poor, moderate and good categories were set as 0-15, 15–21 and 21-28. Mann-Whitney and Kruskal-Wallis test was used to test the association between the demographic profile and knowledge score since the data was not normally distributed. Results: A total of 325 respondents with mean age 39.94 (±13.196) ranged from 18 to 83-year-old participated in this study. Majority were females (71.1%) with pri-mary education (39.1%) and mean household income of RM 615.47 (± 446.79). Their mean knowledge score was 12.82 (±9.671). Majority of them had poor knowledge (51.7%). The respondents with higher education background had significantly better knowledge score compared to lower education background (p
Subclinical changes that occur in the heart at an early age may provide valuable information to outline prevention strategies for cardiovascular diseases. Heart rate variability (HRV) reflects regulation of autonomic balance, heart, and vascular tone, which are the determinants of blood pressure. Therefore, this study aimed to determine the difference in heart rate variability (HRV) of Malay male young adult with their BMI and adiposity level. MATERIALS AND METHODS:A total of 201 Malay male young adult aged between 19 to 24 years old were screened and their BMI and adiposity level were measured. Three non-invasive tests; Valsalva Manoeuvre, orthostatic response and 30/15 ratio of heart rate were performed. Short term HRV time and frequency domains were recorded. RESULTS:Despite few significant differences in HRV parameters of overweight/obese subjects, the result is inconclusive to conclude any reduced variability. However, those with high adiposity regardless of their BMI reported significantly lower mean of R-R SD in time domain and lower mean of LF/HF ratio in frequency domain. The orthostatic reflex results revealed that high adiposity subjects had significantly lower mean of LF and HF. A decrement of -0.28 ms2HF/LF during Valsalva manoeuvre, -0.35 LF ms2in orthostatic reflex and 0.33 ms2in orthostatic reflex per 1% of body fat percentage were observed. CONCLUSION: HRV parameters were inversely proportional to the adiposity level which was suggestive of modulation of sympathetic function can occur at an early age.
The present study aimed to determine the association between chrononutrition behaviors, sugar-sweetened beverage intake, and sleep quality among Malaysian women. A cross-sectional study using a validated, self-administered Chrononutrition Profile Questionnaire, Beverage Questionnaire and Sleep Quality Index were conducted among 934 Malaysian women. Multinomial logistic regression was performed to obtain odds ratios of being overweight/underweight and to test the association with poor sleep quality. 40% of Malaysian women were either overweight or obese and 65.4% had poor sleep quality. We found that breakfast skipping (OR: 4.101; CI: 2.378-7.070), poor evening eating (OR: 4.073; CI: 1.631-10.186), and eating the largest meal at night (OR: 6.970; CI: 1.944-24.994) increased the odds of being underweight. On the other hand, the daily consumption of 100% fruit juices (OR: 1.668; CI: 1.058-1.731), daily consumption of sweetened coffee or tea (OR: 1.707; CI: 1.162-2.508) and consumption of diet soft drinks by 6 times or fewer (OR: 1.484; CI: 1.066-2.064) are associated with increased odds of being overweight. However, when adjusted, only poor evening latency (AOR: 16.638; CI: 1.986-139.383) revealed an increased odd of being underweight. The highest odds predicting poor sleep quality were found for eating the largest meal during dinner (OR: 3.696; CI: 1.967-6.945) and (AOR: 2.194; CI: 1.119-4.304) when adjusted. Hence, the result indicates that multifactorial impacts on women's body weight and recommendations to adjust chrononutrition and sugar-sweetened beverages intake in lifestyle must be done carefully considering other parameters together.
