Physical activity (PA) in the form of structured or unstructured exercise is beneficial for health. This paper aims to study PA levels across four domains according to the International Physical Activity Questionnaire (IPAQ) and its associated factors. A total of 7479 Malaysian adult participants between 18 to 90 years old from the REDISCOVER study who completed the IPAQ were analyzed. PA was calculated as MET-min per week and were categorized according to insufficiently active, sufficiently active and very active. Multinomial regression was used to determine the association between sociodemographic, clinical factors and the level of PA. The mean age of the participants was 51.68 (±9.5 SD). The total reported physical activity in median (IQR) was 1584.0 (0–5637.3) MET-min per week. The highest total for PA was in the domestic domain which is 490 (0–2400) MET-min per week. Factors associated with sufficiently active or very active PA include Malay ethnicity, no formal education, elementary occupation, current smokers and high HDL. Whereas low income, male and normal BMI are less likely to participate in sufficiently active or very active PA. Intervention to encourage higher PA levels in all domains is important to achieve recommended PA targets.

Although prehypertension and hypertension can be detected at the primary healthcare level and low-cost treatments can effectively control its complications, hypertension is still the world's leading preventable risk factor. Therefore, the present study aimed to determine its prevalence and its risk factors among Malaysian adults. A cross-sectional study involving 7585 adults was performed covering the rural and urban areas. Respondents with systolic blood pressure (SBP) of 120-139 mmHg and/or diastolic blood pressure (DBP) of 80-89 mmHg were categorized as prehypertensive, and hypertensive categorization was used for respondents with an SBP of ≥140 mmHg and/or DBP of ≥90 mmHg. Respondents reported to have prehypertension and hypertension were 40.7% and 38.0%, respectively. Those residing in a rural area, older age, male, family history of hypertension, and overweight or obese were associated with higher odds of prehypertension and hypertension. Unique to hypertension, the factors included low educational level (AOR: 1.349; 95% CI: 1.146, 1.588), unemployment (1.350; 1.16, 1.572), comorbidity of diabetes (1.474; 1.178, 1.844), and inadequate fruit consumption (1.253; 1.094, 1.436). As the prehypertensive state may affect the prevalence of hypertension, proactive strategies are needed to increase early detection of the disease among specific group of those residing in a rural area, older age, male, family history of hypertension, and overweight or obese.

The low prevalence of condom usage among youth with Human Immunodeficiency Virus/Sexually Transmitted Diseases (HIV/STDs) is a concern. Condom use self-efficacy has been identified as a significant predictor of condom usage. This cross-sectional study examines the prevalence of good condom usage and its association with condom use self-efficacy among Malaysian urban youth, aged between 18 to 24 years old attending HIV/STDs clinics in primary-care settings, Selangor. Utilising the Harmonised Malay version of Condom Use Self-Efficacy Scale (CUSES M-H) questionnaire, the data from 218 responders were analysed using univariate and multiple logistic regression. The prevalence of good condom usage was 61% (95% CI: 54%, 68%). The average mean score of condom use self-efficacy was 3.07. Condom use self-efficacy was divided into four subscales of mechanics, perceived barriers, assertiveness and intoxicants. The assertiveness subscale had the highest average mean score of 3.42, while the intoxicant subscale score had the lowest average mean score of 2.24. Good condom usage was significantly associated with condom use during first sexual intercourse (aOR = 5.81, 95% CI: 1.97, 17.14), duration diagnosis of HIV/STDs of more than 12 months (aOR = 6.40, 95% CI: 2.30, 17.86) and the high assertiveness subscale score (aOR = 1.19, 95% CI: 1.03, 1.36). A behavioural change campaign that targets high-risk youth in primary care settings could promote condom use self-efficacy particularly assertiveness to increase condom usage among the youth.

Introduction: The older adults (OA) is vulnerable to malnutrition, which may affect their health and quality of life. This study assesses the prevalence of deficiencies in dietary nutrients among the Malaysian OA stratified by residency, genders, socioeconomic status (SES) and body mass index (BMI). Methodology: A cross-sectional study was conducted, utilizing purposive sampling, recruiting 2,299 Malaysian people aged 60 years old and above who agreed to be interviewed via a comprehensive semi-quantitative food frequency questionnaire. The nutrients intake was calculated based on the Malaysian food composition and US Department of Agriculture food composition databases. Then, the nutrients intake was compared with the Malaysian Recommended Nutrients Intake guidelines, and the prevalence of deficiencies in dietary nutrients were calculated. The median (interquartile ranges) intakes of nutrients were compared between residency (urban and rural), genders (male and female), and SES (low and middle-high) using the Mann-Whitney U test. The differences in nutrient intake between BMI categories (underweight, normal, and overweight) were identified using the Kruskal-Wallis test followed by Dunn’s post hoc test. Results: The response rate was 70.3% (n = 2,299), predominantly were females (50.8%), received primary education (76.6%), were currently married (84.3%), were middle–high SES (57.7%), and had a normal BMI (59.8%). There was a notable inadequate intake prevalence of magnesium (100.0%), manganese (97.9%), zinc (95.6%), vitamin B₆ (98.4%), potassium (91.0%), calcium (89.3%), vitamin B₁₂ (80.2%), vitamin E (91.2%), and vitamin K (81.5%) among Malaysian OA. Additionally, significant differences were observed in nutrients intake levels across gender, residency, SES, and BMI within this population. Conclusions: This study shows a high prevalence of dietary nutrients deficiency (> 80%) among the Malaysian OA, particularly for magnesium, manganese, potassium, zinc, vitamin B₆, vitamin E, calcium, vitamin B₁₂, and vitamin K. To improve the nutritional status of OA and safeguard against adverse health effects, it is necessary to formulate and execute strategies to enhance their dietary nutrient intakes. The strategies may involve intervention such as nutrient supplementation and promotion of consuming nutrient-rich foods.

INTRODUCTION: Ultraprocessed grains, commonly consumed in Western diets, undergo refining processes that often remove beneficial components and include additives to enhance taste, texture, or durability, potentially influencing gastrointestinal health. This study examines the association between ultraprocessed grain consumption and the risk of developing inflammatory bowel disease (IBD) using data from the Prospective Urban Rural Epidemiology (PURE) study. METHODS: This analysis included 124,590 participants from 21 countries who had dietary data available in the PURE study. Dietary intake was assessed through validated food frequency questionnaires, and ultraprocessed grain intake was categorized into 3 levels. The primary outcome was the development of IBD, including Crohn's disease (CD) and ulcerative colitis (UC). Multivariate Cox proportional hazard models were used to calculate hazard ratios (HRs), adjusting for confounders including age, sex, smoking status, eating habits, and physical activity. RESULTS: Among 124,590 participants, higher ultraprocessed grain intake was associated with increased IBD risk. Participants consuming ≥19 g/d of ultraprocessed grains had a higher risk of developing IBD compared with those consuming <9 g/d (hazard ratio [HR] 1.86, 95% confidence interval 1.26–2.61, P _trend = 0.0003) after multivariate adjustment. Fresh bread and rice consumption were associated with lower IBD risk. Participants with greater ultraprocessed food intake (≥5 servings per day) were linked to a higher risk of developing IBD compared with those consuming <1 serving per day (HR 3.95, 95% confidence interval 2.74–5.71, P _trend < 0.0001). DISCUSSION: Higher intake of ultraprocessed grains is associated with significantly increased risk of developing IBD. A healthy eating pattern should minimize consumption of ultraprocessed grains. Further studies should be performed to understand which components of ultraprocessed grains may be detrimental for health.
