ABSTRACT
BACKGROUND: High sodium intake was an established risk factor for stroke and cardiovascular diseases. The objective of this study was to investigate factors associated with high sodium intake based on 24-h urinary sodium excretion from the MyCoSS study. METHODS: The cross-sectional survey was conducted among adults aged 18 years and above in Malaysia. A multi-stage stratified sampling was used to represent nationally. Twenty-four-hour urine was collected from a total of 900 respondents. Indirect ion-selective electrode (ISE) method was used to measure sodium intake. Descriptive and logistic regression analysis was applied to determine factors associated with high sodium intake based on 24-h urinary sodium excretion. RESULTS: A total of 798 respondents (76% response rate) completed the 24-h urine collection process. Logistic regression revealed that high sodium intake associated with obese [aOR 2.611 (95% CI 1.519, 4.488)], male [aOR 2.436 (95% CI 1.473, 4.030)], having a waist circumference of > 90cm for adult males [aOR 2.260 ( 95% CI 1.020, 5.009) and >80cm for adult females [aOR 1.210 (95% CI 0.556, 2.631)], being a young adult [aOR 1.977 (95% CI 1.094, 3.574)], and living in urban areas [aOR 1.701 (95% CI 1.094, 2.645)]. CONCLUSION: Adults who are obese, have a large waist circumference, of male gender, living in urban areas, and belonging to the young adult age group were found to have higher sodium intake than other demographic groups. Hence, reduction of salt consumption among these high-risk groups should be emphasised to reduce the risk of cardiovascular diseases.

AIM: Studies on the influence of social support on activity limitation among older persons remain limited. A better understanding of this relationship will help with resource planning and policy making aimed to reduce burden of care. The objective of this study was to assess the influence of social support on limitation in daily living among older persons in Malaysia. METHODS: Data from the National Health and Morbidity Survey 2018, a nation-wide, cross-sectional survey using a two-stage stratified sampling design, were analyzed. A representative sample of individuals aged ≥60 years identified through national sampling frames throughout Malaysia was included. Face-to-face interviews were conducted using validated questionnaires on activities of daily living (ADL) and instrumental ADL (IADL). Social support was measured using the Duke Social Support Index. RESULTS: The overall prevalence of the presence of any limitations in ADL and IADL was 17.0% and 42.9% respectively. Overall prevalence of the older persons with low to fair social support was 30.8% and high to very high social support was 69.2%. Logistic regression analysis identified the following factors as being associated with limitations in ADL and IADL: being female, of older age, having a monthly income Subject(s)

ABSTRACT
BACKGROUND: Typhoid fever causes global morbidity and mortality and is a significant health burden, particularly in low- and middle-income countries. The direct fecal-oral route is the main transmission mode, but indirect environmental transmission could occur, particularly in urban settings. This study aimed to investigate the burden and trend of typhoid fever, reporting the coverage system between government and private practice and pattern of multidrug-resistant (MDR) typhoid cases in the urban Klang Valley area from 2011 to 2015. METHODS: The data from a cross-sectional study retrieved from the e-Notifikasi System, a national reporting system for communicable diseases provided by the Disease Control Division, Ministry of Health Malaysia and secondary data of all the typhoid cases were obtained from the public and private hospitals and laboratories in Klang Valley. Descriptive analysis was performed to examine the sociodemographic characteristics, spatial mapping was conducted to examine trends, and the crude incidence rates of confirmed typhoid cases and percentage of reporting coverage were calculated. Significant differences between MDR and non-MDR Salmonella typhi were determined in the patient's sociodemographic characteristics, which were analyzed using χ2 test. P values < 0.05 were considered statistically significant. RESULTS: In total, 507 typhoid fever cases were reported in Klang Valley; however, only 265 cases were confirmed by culture tests. The crude incidence rates of confirmed cases were between 0.5 to 0.7 but peaked at 1.42 per 100,000 population in 2015. Most typhoid fever cases were observed among men (55.6%), individuals aged 21 to 30 years (27.6%), Malaysians (86.3%) and individuals of Malay ethnicity (52.1%). The reporting coverage of confirmed cases was 78.9% and non-reporting coverage of unconfirmed typhoid cases was 79.5%. The predictive value positive (PVP) was 89.3, and 7.5% were detected as MDR Salmonella typhi. Statistical significance was found in gender, citizenship and ethnicity regarding MDR Salmonella typhi (p = 0.004, p = 0.008 and p = 0.034, respectively). CONCLUSIONS: The local transmission of typhoid is still prevalent in the Klang Valley despite rapid urbanization and development in recent years. These findings are essential for policy makers to plan and implement focused and effective preventative activities to curb typhoid infection in urban areas.

Parental protective factors do play an important role in preventing Internet addiction. A self-administered questionnaire was used to measure health risk behaviors among Malaysian adolescents. The prevalence of Internet addiction was significantly higher among adolescents with perceived lack of parental supervision (30.1% [95% confidence interval (CI) = 28.7-31.4]) and lack of parental connectedness (30.1% [95% CI = 28.5-31.7]), compared with their counterparts. Adolescents who perceived a lack of parental supervision, respect for privacy, connectedness, and bonding were more likely to have Internet addiction: (adjusted odds ratio [aOR] = 1.39; 95% CI = 1.27-1.52), (aOR = 1.23; 95% CI = 1.16-1.31), (aOR = 1.09; 95% CI = 1.02-1.16), (aOR = 1.06; 95% CI = 1.00-1.12), respectively. Among girls, Internet addiction was associated with those who perceived lack in all 4 parental factors, while among boys, those who perceived lack of parental supervision and respect for privacy were more prone to Internet addiction.

INTRODUCTION: Dengue is among the most important mosquito-borne diseases, with more than half of the world's population at risk of infection in dengue endemic countries. Environmental management, which includes any activities that involve environmental modification, environmental manipulation and changes to human behaviour have been used to mitigate the risk of dengue transmission. In this protocol, we will integrate the data from various sources to assess the overall effect of environmental management on the incidence of dengue and other entomological indices. METHODS AND ANALYSES: We will conduct a systematic review of intervention that assess the effect of environmental management on the incidence of dengue and/or entomological indices. We will include any studies that include intervention through environmental management for dengue control, involving environmental modification, environmental manipulation and changes to human behaviour. A comprehensive search will be performed in electronic databases PUBMED, CENTRAL, SCOPUS, Web of Science and relevant research websites such as PROPSERO, WHO ICTRP and ClinicalTrials.gov to identify studies that meet our inclusion criteria. A systematic approach to searching, screening, reviewing and data extraction will be applied based on Preferred Reporting Items for Systematic reviews and Meta-Analysis. Titles, abstract, keywords for eligibility will be examined independently by researchers. The quality of the included studies will be assessed using quality assessment tool for studies with diverse design and Cochrane risk of bias tool. The characteristics of the selected articles will be described based on the study design, types of intervention and outcomes of the study in various countries. These include the types of environmental management intervention methods and the effectiveness of the intervention in reducing dengue cases or incidence and impact on entomological indices. ETHICS AND DISSEMINATION: We will register this systematic review with the National Medical Research Register, Ministry of Health Malaysia. This protocol also had been registered with the PROSPERO. No ethical approval is necessary, as there will be no collection of primary data. The results will be disseminated though a peer-reviewed publication and conference presentation.
