Background: Depression is on the rise and has become a significant concern for public health. Limited research has explored the connection between dietary patterns and depression. This investigation aimed to examine how dietary behaviours relate to depression among adolescents attending school in Malaysia. Methods: The study utilized data from the National School-Based Health Survey 2022, a nationwide survey involving school-going adolescents aged 13–17, with a total of 33,523 participants from 239 schools. To assess depression, the study employed the Patient Health Questionnaire (PHQ-9), considering a score of 10 or higher as indicative of depression. Dietary behaviours were assessed using a validated self-administered questionnaire adapted from the World Health Organization's Global School-based Student Health Survey. Descriptive analysis and complex sample logistic regression were carried out using SPSS version 26.0. Results: The study revealed a 26.9% overall prevalence of depression, with higher risks among female adolescents (AOR 2.71, 95% CI 2.51, 2.92) and those in higher grades. Malays (AOR 1.71, 95% CI 1.41, 2.07), Other Bumiputeras (AOR 1.69, 95% CI 1.32, 2.17), and Others (AOR 1.63, 95% CI 1.16, 2.30) had elevated odds of depression compared to Indians. Healthy dietary habits, like consuming less than two servings of fruits daily, correlated with depression (AOR 1.44 95% CI 1.35, 1.54). Additionally, unhealthy dietary behaviours such as fast food consumption (AOR 1.73 [95% CI 1.55, 1.93]) and carbonated soft drink intake (AOR 1.59 [95% CI 1.48, 1.70]) were positively associated with depression. Conclusions: One out of every four Malaysian adolescents was identified to experience depression. Depression was linked to several factors, such as being female, belonging to higher grade levels, identifying as Malays, Other Bumiputeras, or belonging to other ethnicities, and participating in the consumption of fast food, carbonated soft drinks, and fruits. To address these observations, it is crucial to formulate effective public health programmes that prioritize adolescent mental health and encourage the adoption of healthy eating habits.

Objective: This study aims to determine the prevalence of poor self-rated health (SRH) in Malaysia and its association with sociodemographic characteristics, lifestyle behavior, chronic diseases, depression, and functional limitations in activities of daily living (ADLs) among older persons. Design: Cross-sectional. Setting, participants, and outcome measures: We used data from the National Health and Morbidity Survey 2018, a nationwide community-based study. This study was conducted using a two-stage stratified cluster sampling design. Older persons were defined as persons aged 60 years and above. SRH was assessed using the question “How do you rate your general health?” and the answers were “very good”, “good”, “moderate”, “not good”, and “very bad”. SRH was then grouped into two categories; “Good” (very good and good) and “Poor” (moderate, not good, and very bad). Descriptive and logistic regression analyses were conducted using SPSS version 25.0. Results: The prevalence of poor SRH among older persons was 32.6%. Poor SRH was significantly related to physical inactivity, depression, and limitations in activities of daily living (ADLs). Multiple logistic regression revealed that poor SRH was positively associated with those who had depression (aOR 2.92, 95% CI:2.01,4.24), limitations in ADLs (aOR 1.82, 95% CI: 1.31, 2.54), low individual income (aOR 1.66, 95% CI:1.22, 2.26), physical inactivity (aOR 1.40, 95% CI:1.08, 1.82), and hypertension (aOR 1.23, 95% CI:1.02, 1.49). Conclusions: Older persons with depression, limitations in ADLs, low income, physical inactivity, and hypertension were significantly associated with poor SRH. These findings provide information to aid health personnel and policymakers in the development and implementation of health promotion and disease prevention programs, as well as adequate evidence in planning different levels of care for the older population.

Background: Anaemia continues to be a global public health burden affecting all age groups, particularly children. Indigenous people, including the Orang Asli (OA) population in Malaysia, are at risk of anaemia due to the vast disparities in social determinants of health in their population compared to the non-indigenous population. Objectives: This review aimed to identify the prevalence and risk factors of anaemia among OA children in Malaysia and analyse the knowledge gaps. Methods: A systematic search was conducted in PubMed, Cochrane Library, Scopus and Google Scholar databases. This review followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for scoping reviews (PRISMA-ScR) guidelines. Results: This review identified six studies involving the participation of OA children from eight subtribes residing in Peninsular Malaysia. The overall prevalence of anaemia among OA children ranged from 21.6 to 80.0%, with iron deficiency anaemia prevalence at 34.0%. The risk factors of anaemia among OA children reported from one study in this review were being younger than ten years old children (AOR 2.11 (95% CI 1.23, 3.63)) and moderate to heavy Ascaris infections (AOR 2.05 (95% CI 1.12, 3.76)). There was no data from OA children from certain age groups and subtribes. Additionally, there is a paucity of data on risk factors for anaemia among OA children from the currently available evidence. Conclusion: The prevalence of anaemia among OA children poses a moderate to severe public health concern. Therefore, more comprehensive studies in the future are needed to address the gaps identified in this review, primarily regarding anaemia risk factors. This data would encourage policymakers in devising effective national prevention strategies to improve morbidity and mortality among OA children in the future.

Background: Inadequate knowledge of human immunodefciency virus (HIV) is underscored as a key factor contributing to the HIV epidemic. Nonetheless, current data on HIV knowledge in Malaysia are still scarce. Therefore, this study aimed to assess the prevalence of inadequate HIV knowledge and its associated factors among the general Malaysian population. Method: The study utilized data from the National Health and Morbidity Survey (NHMS) 2020, a nationwide cross-sectional survey employing a two-stage stratifed random sampling technique to ensure national representativeness. HIV knowledge was assessed using the UNGASS indicators questionnaire, which comprises five questions on HIV prevention and transmission. The data were collected using the computer assisted telephone interviewing (CATI) method. Respondents who did not correctly answer all five questions were considered to have inadequate knowledge about HIV. Descriptive analysis and complex sample logistic regression were performed using SPSS version 28.0. Results: The survey identifed 5,561 eligible respondents, leading to the participation of 3,187 individuals in the second phase of the study, which resulted in a response rate of 57.3%. Our study revealed an overall prevalence of inadequate HIV knowledge at 77.4%, with adolescents aged 13–19 exhibiting the highest prevalence at 86.1%. Multiple logistic regression analysis indicated that respondents with no formal education (aOR 4.34, 95% CI: 0.65, 29.08) were over four times more likely to lack HIV knowledge. Additionally, respondents with only secondary education had an increased risk of 1.79 times. Individuals residing in rural areas were signifcantly more likely to have inadequate HIV related knowledge. Furthermore, respondents who worked as unpaid workers, homemakers, or caregivers (aOR 1.71, 95% CI: 1.05, 2.82) showed a higher likelihood of lacking HIV knowledge. Conclusion: Three out of four individuals in the general Malaysian population were found to lack sufficient knowledge about HIV. This underscores the need for targeted interventions in HIV education, particularly in rural areas and among populations with lower educational attainment. Additionally, digital platforms and youth-focused campaigns could be especially efective for reaching adolescents. Policymakers must prioritize inclusive, accessible HIV prevention strategies to address these gaps and reduce transmission rates.
