Body Weight, Body Weight Perception, and Bullying Among Adolescents in Malaysia.

Asia Pac J Public Health 2019 11 16;31(8_suppl):38S-47S. Epub 2019 Oct 16.

Body weight is a factor, with body weight perception a mediator, toward being a victim of bullying. This study aimed to explore the association between body weight, body weight perception, and bullying among students 13 to 17 years of age in Malaysia. Data were collected using a self-administered questionnaire. A 2-stage stratified cluster sampling design was used, and 212 schools across Malaysia were selected for this survey. Body weight was measured and body weight perception was the student's reflection of their body weight. The prevalence of being bullied among adolescents in Malaysia was 16.2%. Being too thin or being obese increased the probability of being bullied. Students with a normal body mass index, but with a misperception of their body weight, also had increased odds of being bullied. Obesity prevention, together with instilling positive body weight perception, should be part of all programs directed toward tackling the problem of bullying.

Environmental management for dengue control: a systematic review protocol.

BMJ Open 2019 05 15;9(5):e026101. Epub 2019 May 15.

Institute for Public Health, Kuala Lumpur, Wilayah Persekutuan, Malaysia.

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.

Environmental risk factors of leptospirosis in urban settings: a systematic review protocol.

BMJ Open 2019 01 21;9(1):e023359. Epub 2019 Jan 21.

Center for Communicable Disease Research, Institute for Public Health, Kuala Lumpur, Malaysia.

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.
