    Salmonella enterica serovar Enteritidis infection is a common concern in poultry production for its negative effects on growth as well as food safety for humans. Identification of molecular markers that are linked to resistance to Salmonella Enteritidis may lead to appropriate solutions to control Salmonella infection in chickens. This study investigated the association of candidate genes with resistance to Salmonella Enteritidis in young chickens. Two native breeds of Malaysian chickens, namely, Village Chickens and Red Junglefowl, were evaluated for bacterial colonization after Salmonella Enteritidis inoculation. Seven candidate genes were selected on the basis of their physiological role in immune response, as determined by prior studies in other genetic lines: natural resistance-associated protein 1 (NRAMP1), transforming growth factor β3 (TGFβ3), transforming growth factor β4 (TGFβ4), inhibitor of apoptosis protein 1 (IAP1), caspase 1 (CASP1), lipopolysaccharide-induced tumor necrosis factor (TNF) α factor (LITAF), and TNF-related apoptosis-inducing ligand (TRAIL). Polymerase chain reaction-RFLP was used to identify polymorphisms in the candidate genes; all genes exhibited polymorphisms in at least one breed. The NRAMP1-SacI polymorphism correlated with the differences in Salmonella Enteritidis load in the cecum (P = 0.002) and spleen (P = 0.01) of Village Chickens. Polymorphisms in the restriction sites of TGFβ3-BsrI, TGFβ4-MboII, and TRAIL-StyI were associated with Salmonella Enteritidis burden in the cecum, spleen, and liver of Village Chickens and Red Junglefowl (P < 0.05). These results indicate that the NRAMP1, TGFβ3, TGFβ4, and TRAIL genes are potential candidates for use in selection programs for increasing genetic resistance against Salmonella Enteritidis in native Malaysian chickens.

    BACKGROUND: Emotional and behavioral problems (EBD) or mental health problems in children and adolescents are an important public health issue, but there has been no evaluation to date of the extent of such problems in near-developed countries. This study evaluated the prevalence and stability of EBD among children in Malaysia.

    METHODS: This research comprises a longitudinal population-based study that measured the prevalence and 6-month stability of EBD in children aged seven to eight years and thirteen to fourteen years attending public schools in Malaysia based on parents, teachers and children's (aged 13 to 14 years) report of the Strengths and Difficulties Questionnaire (SDQ) at baseline and 6 months later.

    FINDINGS: The prevalence of EBD in Malaysian school children was 9.3% for teacher-report, 8.5% for parent-report and 3.9% for child-report. There was no significance difference in the prevalence of emotional and behavioral problems over six-months for all informants, except for teacher-report Emotional and Conduct problems scores which increased significantly and child-report Total Difficulties and Emotional problems scores which decreased significantly (p < 0.05).

    CONCLUSIONS: This study shows that the prevalence of EBD among Malaysian children is almost similar to the Western countries and stable over a 6-month period. These findings suggest the need for policy makers in near-developed countries to provide services aimed at preventing EBD and treating children identified as having such problems.

    Introduction: Mental health problem is an important public health issue which causes deterioration in quality of life, function and financial capabilities. According to the National Health and Morbidity Survey (NHMS) 1996, the prevalence of mental problem among adults in Malaysia was 10.7% and this has increased to 29.2% in NHMS 2015. The aim of this study was to evaluate the burden of depression, anxiety and stress among adults in a city in Klang Valley, Malaysia including its associated factors.
    Methods: A cross-sectional study was conducted by analysing secondary data obtained from screening program performed in six primary health clinics in the city throughout 2016. There were 576 adults participated in the screening program which consisted of mental health screening using Depression, Anxiety, Stress 21 (DASS-21) questionnaire and health status screening using Health Status Screening Form.
    Results: The prevalence of depression was 20.5%, anxiety was 44.5%, while stress was 10.1%. By using logistic regression, history of being abused was the only significant protective factor associated with depression, anxiety and stress with OR of 0.062 (95% CI 0.007; 0.563, p=0.004), OR of 0.001 (95% CI 0.000; -, p=0.001) and OR of 0.026 (95% CI 0.003; 0.238, p<0.001) respectively. Other independent variables were not statistically significant.
    Conclusions: As conclusions, surprisingly the risk of depression, anxiety and stress were not increased among participants who reported history of being abused. This was probably due to good coping mechanism among them. Nevertheless, early intervention needs to be emphasized to prevent mental disorders among this group of people in community.

    INTRODUCTION: Adolescents' involvement in sexual practices are becoming a major public health concern in Malaysia. This study aims to determine the prevalence of sexual practices among Malaysian school-going adolescents and its predictive factors.

    METHODS: A cross-sectional study was carried out from April 2012 till September 2012 among 16-year-old school adolescents from two different schools. They were selected through simple random sampling and these adolescents answered a self-administered questionnaire consisting of three sections i.e. socio-demography, risk-taking behaviours and family-adolescents relationship. Data were analysed using Pearson Chi-Square test while Simple Logistic Regression and Multiple Logistic Regression were applied to determine the predictive factors.

    RESULTS: The prevalence of sexual practices among the adolescents was 30.1% in which they were either involved in pornography (26.8%), pre-sexual activities (8.5%) or premarital sex (2.9%). Six predictive factors associated with sexual practices among this age group were identified which were male (adjusted Odds Ratio (aOR) 2.7, 95% Confidence Interval (95%CI) 1.4 to 2.5), truancy (aOR 2.3, 95%CI 1.3 to 4.2), bully (aOR 3.5, 95%CI 1.7 to 7.3), hanging out (aOR 2.8, 95% 1.4 to 5.6), staying out late (aOR 3.2, 95%CI 1.5 to 6.8) and conflict with family (aOR 4.1, 95%CI 1.9 to 8.9).

    DISCUSSION: Asian background differs from the western countries and findings of this study may suggest suitable intervention programmes that can prevent high-risk sexual practices among Asian school-going adolescents.

    PURPOSE: Gastrointestinal (GI) cancer has emerged as a major health problem. Cancer patients receive informal care from their families beyond formal care. There has been little evidence showing how the health-related quality of life (HRQOL) of the caregivers differs from that of the GI patients in Malaysia. A cross-sectional study was conducted in three referral hospitals in Malaysia. The objectives of this study were to determine the HRQOL of GI cancer patients and their family caregivers, and assess whether there is any significant relationship between the demographic factors, and the physical component summary (PCS) and mental component summary (MCS) scores for patients and caregivers.

    METHODS: A total of 323 dyads of GI cancer patients and their caregivers completed the Medical Outcomes Study 12-item Short Form (MOS SF-12) questionnaire to measure their HRQOL during face-to-face interviews. The analyses were performed using SF-12 scoring software to compute PCS and MCS scores (HRQOL parameters). The independent t test, one-way ANOVA, and the Pearson correlation test were conducted to determine the demographic factors related to the HRQOL of the dyads.

    RESULTS: The caregivers had higher scores in all domains for the SF-12 than the patients. There were significant differences found in the MCS scores of the patients according to ethnicity, origin of cancer, duration of cancer, and surgery. None of these factors had a significant relationship with the caregivers' HRQOL.

    CONCLUSION: Caregivers had better HRQOL than cancer patients. Early intervention for cancer patients in the form of counselling and personalised pain management may enhance the HRQOL of patients.

    BACKGROUND: The patient's intention to engage in diabetes care is the hallmark of role acceptance as a health manager and implies one's readiness to change. The study aimed to understand the process of having the intention to engage in diabetes care.

    METHODS: A qualitative study using narrative inquiry was conducted at a public primary care clinic. Ten participants with type 2 diabetes of more than a 1-year duration were selected through purposive sampling. In-depth interviews were conducted using a semi-structured protocol guide and were audio-taped. The interviews were transcribed and the texts were analyzed using a thematic approach with the Atlas.ti ver. 8.0 software (Scientific Software Development GmbH, Berlin, Germany).

    RESULTS: Three themes emerged from the analysis. The first theme, "Initial reactions toward diabetes," described the early impression of diabetes encompassing negative emotions, feeling of acceptance, a lack of concern, and low level of perceived efficacy. "Process of discovery" was the second overarching theme marking the journey of participants in finding the exact truth about diabetes and learning the consequences of ignoring their responsibility in diabetes care. The third theme, "Making the right decision," highlighted that fear initiated a decision-making process and together with goal-setting paved the way for participants to reach a turning point, moving toward engagement in their care.

    CONCLUSION: Our findings indicated that fear could be a motivator for change, but a correct cognitive appraisal of diabetes and perceived efficacy of the treatment as well as one's ability are essentially the pre-requisites for patients to reach the stage of having the intention to engage.

    Salmonella Enteritidis is a major cause of food poisoning worldwide, and poultry products are the main source of S. Enteritidis contamination for humans. Among the numerous strategies for disease control, improving genetic resistance to S. Enteritidis has been the most effective approach. We investigated the association between S. Enteritidis burden in the caecum, spleen, and liver of young indigenous chickens and seven candidate genes, selected on the basis of their critical roles in immunological functions. The genes included those encoding interleukin 2 (IL-2), interferon-γ (IFN-γ), transforming growth factor β2 (TGF-β2), immunoglobulin light chain (IgL), toll-like receptor 4 (TLR-4), myeloid differentiation protein 2 (MD-2), and inducible nitric oxide synthase (iNOS). Two Malaysian indigenous chicken breeds were used as sustainable genetic sources of alleles that are resistant to salmonellosis. The polymerase chain reaction restriction fragment-length polymorphism technique was used to genotype the candidate genes. Three different genotypes were observed in all of the candidate genes, except for MD-2. All of the candidate genes showed the Hardy-Weinberg equilibrium for the two populations. The IL-2-MnlI polymorphism was associated with S. Enteritidis burden in the caecum and spleen. The TGF-β2-RsaI, TLR-4-Sau 96I, and iNOS-AluI polymorphisms were associated with the caecum S. Enteritidis load. The other candidate genes were not associated with S. Enteritidis load in any organ. The results indicate that the IL-2, TGF-β2, TLR-4, and iNOS genes are potential candidates for use in selection programmes for increasing genetic resistance against S. Enteritidis in Malaysian indigenous chickens.

    OBJECTIVE: To identify the key factors that contribute to the successful scale-up of pilot projects, with emphasis on factors that are proven helpful in the successful scaling up of health interventions.

    METHODS: Grey literature was searched at the library of the University of Kebangsaan, Malaysia, on database engines Google Scholar and Science Direct with specific key words to screen papers published from January 2001 to June 2016. They were reviewed to identify the key factors affecting scaling up of health-related pilot projects. Full-text articles were selected, and their reference lists were checked to look for relevant papers. They were short-listed and analysed using thematic approach.

    RESULTS: Of the 47 articles initially screened, 14(29.78%) were shortlisted. Thematic analysis of the selected articles suggested several key factors contributed to the successful scale-up of pilot projects. These factors included evidence-based and effective intervention, community readiness, government support, stakeholders' engagement, and monitoring and supervision.

    CONCLUSIONS: To maximise health coverage in developing and low middle-income countries, scaling up of health interventions on a large scale is essential to improve the health and wellbeing of people. The identified key factors should be considered while planning the scale-up of any health project.

    BACKGROUND: The presence of homelessness in Malaysia is not a new issue. The existence of homeless population is growing, along with the development of this country. With the increasing number of homelessness, the range of issues, such as health services financier among them, has surfaced. However, there was limited study conducted on this subject. The main objective of this study was thus, to identify the financier of health services among the homelessness in Kuala Lumpur and factors associated with it.

    METHODS: In this cross-sectional study, we include 196 homeless people aged above 18 years, Malaysian who were able to communicate with interviewers, and respondents who were not aggressive. These respondents were transits at Pusat Transit Gelandangan Kuala Lumpur and Anjung Singgah Kuala Lumpur and were available during interview sessions. They were selected via simple random sampling and were interviewed via face to face guided interviews using a validated structured questionnaire. Data were analysed descriptively, as well as using bivariate and multivariate analysis to explore the associated factors.

    RESULTS: The study showed that 57.7% homeless utilized the health services with only 37.8% assessed government health services. Only 42.5% of the respondents use their own money and 46.9% received aids to finance their health. Major influencing factors that influence homeless people to use their own money for health services were education level, income and disability, with adjusted OR (95% CI) of 3.15 (1.07-9.25), 0.08 (0.029-3.07) and 0.05 (0.003-0.88) while p value was 0.037,

    Anemia in pregnancy is a public health concern. It has been diagnosed in 27% of pregnant women in Malaysia and up to 40% of pregnant women globally. This study aimed to develop and evaluate the effectiveness of an intervention initiative based on the health belief model. The MyPinkMom program was disseminated through a mobile messaging application to pregnant women to educate them on the prevention of anemia in pregnancy. We conducted a two-arm cluster-assignment, single-blinded, randomized control trial at two government antenatal clinics in Selangor. One clinic was randomly chosen as the intervention group, and the other was chosen as the control group. Sixty pregnant women with anemia from the intervention group received the MyPinkMom intervention program in the form of six infographic video clips, and 60 pregnant women with anemia from the control group received routine counseling on anemia in pregnancy. Pregnant women who had anemia secondary to hemoglobinopathy or other chronic diseases were excluded from this study. MANOVA showed significant increases in hemoglobin, knowledge, attitude, subjective norms, and perceived behavioral control scores for adherence to iron supplements, dietary iron, and dietary vitamin C intake (p < 0.001) in the intervention group at week 6. A significant reduction also occurred in dietary tannin intake (p < 0.001) in the intervention group at week 6. The intervention group at week 6 showed a large effect on hemoglobin level increments (partial eta squared, Ƞp2 0.268), dietary iron intake (Ƞp2 0.213), knowledge of anemia in pregnancy (Ƞp2 0.622), subjective norm scores for adherence to iron supplements (Ƞp2 0.167), and reduction in dietary tannin intake (Ƞp2 0.353). Similarly, repeated measures ANOVA showed that changes in hemoglobin levels were significantly different over time (i.e., at baseline, week 6, and week 12) between the intervention and control groups (p < 0.001). Hemoglobin increased rapidly over time among participants in the intervention group but gradually in the control group. To conclude, the newly developed MyPinkMom program that was delivered through a messaging application showed effectiveness in preventing anemia during pregnancy.

    INTRODUCTION: Diabetes mellitus in pregnancies is associated with adverse outcomes both for the mothers and babies. Postponing pregnancy in unoptimized conditions and stabilisation of glucose should be prioritized. This scoping review is aimed to determine the scope and at the same time map the types of evidence available that is related to family planning behaviours among women with diabetes mellitus, with a particular focus on their factors which influence family planning usage and subsequently enable the identification of knowledge gaps in preventing unintended pregnancies among this high-risk population.

    METHODS: This scoping review is guided by the methodological framework by Arksey and O'Malley's and Prisma-ScR checklist. PubMed, EBSCO and OVID were searched for empirical studies between 2000 and February 2022 using the search terms "family planning", "contraceptive" and "diabetes mellitus". Data were summarized according to the study characteristics and levels of factors influencing family planning behaviours.

    RESULTS: Thirty-five articles that met the eligibility criteria included 33 quantitative studies, one qualitative study and one mixed-methods study. The prevalence of family planning methods used by women with diabetes mellitus varied ranging from 4.8 to 89.8% among the studied population. Women with diabetes mellitus were reported to be less likely to utilise any family planning methods compared to women without diabetes mellitus.

    CONCLUSIONS: Most of the evidence to date on family planning behaviours among women with diabetes mellitus focuses on the role of individual level sociodemographic factors. Few studies focused on exploring determinants at multiple levels. In this review we found that there is limited evidence on disease control and pregnancy intention in relation to their family planning practices. Future studies with more clinical and contextual factors are needed to guide the strengthening of family planning services for high-risk group women specifically for women with diabetes mellitus.

    Objective: This study examined the quality of life (QOL) of caregivers for gastrointestinal (GI) cancer patients, and associated factors. Methods: A cross-sectional study was conducted at three referral hospitals in Klang Valley, Malaysia. A total of 323 pairs of patients and caregivers from the oncology units of these hospitals completed questionnaires in Malay. The QOL of caregivers was measured using The Malay Caregiver Quality of Life questionnaire. The independent variables were caregiver and patient factors, care-related factors, the Caregiver Strain Index-Malay, and the Multidimensional Scale of Perceived Social Support-Malay. Simple and multiple linear regression analyses were performed to determine the factors associated with the QOL. Variables with p < 0.05 were considered significant in the multiple analyses. Results: Female caregivers were 68.1% of the total, and 46.4% caregivers were spouses to cancer patients. Their mean age was 44.50 (13.29) years old. About 51.7% were of Malay ethnicity. The mean score for QOL was 80.17 (21.58). Being a male caregiver (beta = 5.165, p = 0.011) and of Indian ethnicity (beta = -9.163, p = 0.001) were strongly associated with caregiver QOL. Male patients contributed higher QOL scores for the caregivers compared to female patients. There was an inverse relationship among caregiving strain, duration of caregiving, and caregiver QOL. Conclusion: The identification of factors that affect QOL will allow healthcare providers to develop appropriate interventions. It is important that caregivers be in good health so as not to compromise the care they provide to their patients.

    BACKGROUND: Physical inactivity in pregnancy has been associated with excessive gestational weight gain, hypertensive disorders, gestational diabetes mellitus and postpartum depression. Despite these risks, physical inactivity level remains high especially in higher income countries. The prevalence of physical inactivity among women in Malaysia aged ≥16 years was 28.2% in 2019 exceeding men by 6.1%. However, little is known regarding the subpopulation of pregnant women especially in Kuala Lumpur which is the most urbanized and highly populated city in Malaysia. Therefore, the aim of this study is to measure the physical inactivity prevalence among first trimester pregnant women in Kuala Lumpur and to identify its determining factors.

    METHODS: This was a cross-sectional study in which 339 first trimester pregnant women were sampled from 13 maternal and child health clinics located in all four parliament districts of Kuala Lumpur. Self-administered questionnaires which contained the Malay version of the pregnancy physical activity questionnaire (PPAQ) were used. Descriptive analysis was conducted to determine the physical inactivity prevalence followed by simple and multiple logistic regression to identify the determinants of physical inactivity with significant level of 5%.

    RESULTS: The prevalence of physical inactivity was 38.3%. The highest activity was seen in the household activity domain, despite only 24.8% of the respondents were housewives/unemployed. There was little to no participation observed in the vigorous intensity category. The determinants of physical inactivity were primigravida (aOR 3.54 95% CI 1.40, 8.97), education level (aOR 3.77 95% CI 1.35, 10.52) and body mass index (aOR 0.88 95% CI 0.80, 0.97) which explained 22.6% variation of physical inactivity in the final adjusted model.

    CONCLUSION: The prevalence of physical inactivity among first trimester pregnant mothers in this study was 38.3%, and the highest activity was seen in the household category. Health education on physical activity in pregnancy should be focused on those who are primigravida and have no tertiary education. The educational content should be updated and tailored to current pandemic situation where self-isolation is the new norm, by advocating for home-based, moderate to vigorous intensity physical activities.

    Recent years have witnessed an emerging trend of e-cigarette smoking in Southeast Asia. On the basis of Malaysian perspectives, this cross-sectional study explored the relationship between e-cigarette smoking behaviour and variables such as perceived health benefit, the desire to quit, social acceptance, social impact and product usefulness. Individuals aged 17 years old and older were recruited via purposive convenience sampling, yielding a total sample of 503 respondents. Collected data were analysed via partial least squares-structural equational modelling. The results showed that perceived heath benefit (β = 0.19, P < 0.01), social acceptance (β = 0.23, P < 0.01) and social impact (β = 0.49, P < 0.01) positively influence e-cigarette smoking behaviour. No such effect is exerted by the desire to quit smoking (β = 0.08, P < 0.05) and product usefulness t (β = -0. 10, P < 0.05). Future studies should examine whether demographic variables affect e-cigarette smoking behaviour.

    Mental health problems are a major public health issue, particularly among children. They impair children's development, academic achievement, and ability to live a productive life. The present study aimed to determine the prevalence and factors associated with mental health problems among children aged 5 to 15 years old in Malaysia. Data from the National Health and Morbidity Survey (NHMS) 2015 were analyzed. A validated Strengths and Difficulties Questionnaire (SDQ) was used. The overall prevalence of mental health problems among children in Malaysia was 11.1%. Multiple logistic regression analysis revealed that for every year increment in age, mental health problems decreased by 5%. Further analysis found that children who had fathers with a non-formal education and worked in the private sector, had parents who were widowed or divorced, and had either parent with mental health problems were more likely to have mental health problems themselves. Children from the lower socioeconomic group and who had either parent with mental health problems had higher odds of having mental health problems in Malaysia.

    Poor management of hazardous waste can lead to environmental pollution, injuries, and adverse health risks. Children's exposure to hazardous waste may cause serious acute and chronic health problems due to their higher vulnerability to the toxic effects of chemicals. This study examines an incident of illegal chemical dumping in Pasir Gudang, Malaysia and its potential health impacts on children. The study introduced a risk assessment of possible health-related effects due to chemical contamination based on a real case scenario where quantification of the contamination was not feasible. A literature review and spatial analysis were used as research methods. On 6th March 2019, tons of hazardous waste were illegally disposed into Kim Kim River, Pasir Gudang, Malaysia. They were identified as benzene, acrolein, acrylonitrile, hydrogen chloride, methane, toluene, xylene, ethylbenzene, and d-limonene. As a result, 975 students in the vicinity developed signs and symptoms of respiratory disease due to the chemical poisoning. The findings of this study indicate that more effective policies and preventive actions are urgently needed to protect human health, especially children from improper hazardous waste management.

    OBJECTIVE: To evaluate the retinal nerve fiber layer (RNFL) and macular thicknesses and identify systemic risk factors for thinning of these layers in patients with metabolic syndrome (MetS).

    METHODOLOGY: A cross-sectional observational study was performed on patients diagnosed with MetS and compared to normal controls. All patients underwent ophthalmic and anthropometric examination, serological and biochemical blood investigations; and ocular imaging using spectral-domain optical coherence tomography. Patients with ocular pathology were excluded. Unpaired t-test was used to compare mean thickness between the two groups. One-way ANOVA with Bonferroni correction for multiple comparisons was used to compare mean thickness between different tertiles of MetS parameters, and a generalized estimating equation was used to correct for inter-eye correlation and to assess association between mean thickness and covariates.

    RESULTS: Two hundred and forty-eight eyes from 124 participants (1:1 ratio of MetS patients to controls) were included. Age ranged between 30 to 50 years old, and mean age was 40 ± 6.6 years. RNFL thickness was lower globally (93.6 ± 9.9 μm vs 99.0 ± 9.3, p<0.001) and in the inferior (124.5 ± 17.5 μm vs 131.0 ± 16.4 μm, p = 0.002), superior (117.2 ± 16.0 μm vs 126.3 ± 14.4 μm, p<0.001) and temporal (65.5 ± 10.2 μm vs 69.5 ± 9.8, p = 0.002) sectors in MetS patients compared to controls. Only the central (237.0 ± 14.0 μm vs 243.6 ± 18.0 μm, p = 0.002) and inferior parafoveal (307.8 ± 20.9 vs 314.6 ± 14.6, p = 0.004) area of the macula was significantly thinner. The inferior RNFL sector had the most difference (mean difference = 9.1 μm). The Generalized Estimating Equation found that, after adjusting for age, diastolic blood pressure, BMI, HDL and obesity; the number of MetS components and elevated triglyceride levels were independent risk factors for reduced thickness in global RNFL (β = -4.4, 95% CI = -7.29 to -1.5, p = 0.003) and inferior parafovea (β = -6.85, 95% CI = -11.58 to -2.13, p = 0.004) thickness respectively.

    CONCLUSION: RNFL thinning was seen more than macula thinning in MetS patients, suggesting RNFL susceptibility to neurodegeneration than the macula. A higher number of metabolic components and elevated triglyceride levels were independent risk factors for retinal thinning in this group of patients.

    This investigation was performed in Kota Kinabalu, Sabah state, where the highest number of pregnancies is recorded. The purpose of this study was to determine variables associated with hazardous sexual activity and adolescent pregnancy in Sabah, Malaysia. The findings indicate that familial variables, peer interactions, self-esteem, psychiatric concerns, economic considerations, and sex knowledge all play a significant role in hazardous sexual conduct and adolescent pregnancy in Sabah, Malaysia. Information obtained from this study will help the Malaysian government and other officials to design and establish proper interventions that will help alleviate the challenge of high prevalence of teenage pregnancy. It is suggested that sex education be included in the high school curriculum, along with physical and health education in Sabah, Malaysia.
