This study aimed to assess the prevalence and factors associated with bullying victimization from a nationwide school-based survey among 27 458 students aged 13 to 17 years. The overall prevalence of having been bullied in the past 30 days was 16.2%; this decreased with age. Multivariate logistic regression analysis revealed that factors most strongly associated with bullying victimization were exposure to physical attacks (adjusted odds ratio [aOR] = 2.46, 95% confidence interval [CI] = 2.17-2.79), illicit drug use (aOR = 2.44, 95% CI = 1.78-3.34), involvement in physical fights (aOR = 1.97, 95% CI = 1.74-2.23), being younger than 14 years (aOR =1.95, 95% CI = 1.59-2.38), and having ever attempted suicide (aOR = 1.83, 95% CI = 1.51-2.21). Other significantly associated factors include loneliness, truancy, making suicidal plans, and symptoms of depression, anxiety, and stress. Exposure to bullying victimization can result in negative lifelong sequelae and important associated factors should be considered in planning effective school-based anti-bullying interventions.

Among several vector control methods commonly used, environmental management is one of the control measures to mitigate dengue in such vulnerable communities. Since there is no curative treatment for dengue yet, targeted environmental and ecosystem management is increasingly relevant. Hence, this review was conducted to identify the effectiveness of environmental management intervention strategy to reduce dengue cases. We searched PUBMED, CENTRAL, SCOPUS, Web of Science, CIJE, WHO ICTRP, and ClinicalTrials.gov up to January 2021. A total of 521 articles were screened. Only 16 studies were included in this review. There were 6 studies that applied all three types of environmental management interventions (manipulation, modification and behavior), 8 studies applied two types of interventions (manipulation and behavior) and 2 studies applied one type of intervention (manipulation or behavior). All included studies reported reduction of Aedes entomological indices. The studies showed reduction in dengue cases and density of Aedes population through environmental interventions. It is recommended for the health authority to incorporate environmental management intervention in dengue control activities and enhanced the community involvement to ensure sustainability with high impact on dengue reduction.

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. Trial registration number CRD42018092189.

Physical fighting among adolescents is one manifestation of interpersonal violence that is an important issue globally, but attention to this problem in Malaysia has been limited. We analyzed data available from the Malaysia Global School-Based Health Survey conducted in 2012. Of the 25 507 respondents, 27.4% reported having been in a physical fight in the past 12 months. Being bullied (adjusted odds ratio [aOR] = 3.01; 95% confidence interval [CI] = 2.67-3.39) was significantly and highly associated with involvement in physical fighting. Smoking (aOR = 2.56; 95% CI = 2.20-2.97), males (aOR = 1.77; 95% CI = 1.62-1.93), using drugs (aOR = 1.73; 95% CI = 1.09-2.15), and drinking alcohol (aOR = 1.42; 95% CI = 1.24-1.63) were other factors associated with physical fighting. Parental supervision showed no significant association with physical fighting. These findings indicate that more attention needs to be given to bullying at school by school authorities and parents.

Objective: This study determined the prevalence of food label reading and understanding among the Malaysian adults, types of labels being read and factors associated with not reading labels. Methods: Malaysian Adult Nutrition Survey 2014 was a cross-sectional and applied a multistage stratified cluster sampling of living quarters. A total of 4044 adults aged 18-59 years were randomly chosen in selected households to represent the Malaysian adult’s population. Data collection was carried out between March to June 2014. Trained data collectors conducted interview using a validated food label questionnaire to obtain information on whether the respondents read labels (every time they bought or received food) and types of information being read. Complex sample analysis was applied to describe the findings. Result: A total of 2992 respondents (1382 men and 1610 women) answered the questionnaire. About 55.0% of the respondents reported never read labels, sometimes read labels was 22.0% and always read labels was 23.0%. Male sex, lower education, being single (not married/divorced/ widow/widower) and normal weight respondents were significantly less likely to read food label information. Among those who read labels, the expiry date was the most common label information being read (91.8%), followed by the precautionary statement (65.9%). Nutrient information being read was carbohydrate and sugar (21.5%), fat (20.0%) and total energy (14.4%). Nonworking respondents and primary school attainers were significantly less likely not to understand label information. Conclusion: Only half of Malaysian adults read the label when buying or receiving food. Expiry date was the most frequently read information and the prevalence of reading the nutrient information was low. These findings provide useful evidence for the health authorities to plan for nutrition intervention programs in order to increase the food label usage among the relevant target groups.

Introduction Leptospirosis is the most common zoonotic disease that causes morbidity and mortality worldwide. The disease can cause sporadic epidemics and recent epidemics have become more apparent in urban localities. There is lack of documented evidence on the specific risk factors of leptospirosis infection among the urbanites, thereby impeding initiatives for prevention in urban settings. We aim to systematically search published articles and synthesise evidence on the risk factors associated with leptospirosis infection among the susceptible populations in urban localities, particularly to identify the risk factors of non-recreational leptospirosis infection. Methods and analysis We will conduct a systematic review of observational studies that investigated environmental risk factors of leptospirosis in urban localities. The search will be performed for any eligible articles from selected electronic databases from 1970 until May 2018. The study will include any studies that investigated risk factors of confirmed leptospirosis cases who acquired the infection in urban locality, particularly exposures from the non-recreational and non-water-related activities. Study selection and reporting will follow the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and Meta-Analysis of Observational Studies in Epidemiology guideline. All data will be extracted using a standardised data extraction form and quality of the studies will be assessed using the Newcastle-Ottawa Scale guideline. Descriptive and meta-analysis will be performed by calculating the standardised median ORs and risk ratios for types of the non-recreational risk factors stratified by social, living conditions and environmental exposures, types of reservoirs and transmissions and types of activities and employments associated with leptospirosis infection in urban locality. Ethics and dissemination No primary data will be collected thus no formal ethical approval is required. The results will be disseminated though a peer-reviewed publication and conference presentation. PROSPERO registration number CRD42018090820.
