Design and Testing of Novel Lethal Ovitrap to Reduce Populations of Aedes Mosquitoes: Community-Based Participatory Research between Industry, Academia and Communities in Peru and Thailand.

BACKGROUND: Dengue virus (and Chikungunya and Zika viruses) is transmitted by Aedes aegypti and Aedes albopictus mosquitoes and causes considerable human morbidity and mortality. As there is currently no vaccine or chemoprophylaxis to protect people from dengue virus infection, vector control is the only viable option for disease prevention. The purpose of this paper is to illustrate the design and placement process for an attractive lethal ovitrap to reduce vector populations and to describe lessons learned in the development of the trap. METHODS: This study was conducted in 2010 in Iquitos, Peru and Lopburi Province, Thailand and used an iterative community-based participatory approach to adjust design specifications of the trap, based on community members' perceptions and feedback, entomological findings in the lab, and design and research team observations. Multiple focus group discussions (FGD) were held over a 6 month period, stratified by age, sex and motherhood status, to inform the design process. Trap testing transitioned from the lab to within households. RESULTS: Through an iterative process of working with specifications from the research team, findings from the laboratory testing, and feedback from FGD, the design team narrowed trap design options from 22 to 6. Comments from the FGD centered on safety for children and pets interacting with traps, durability, maintenance issues, and aesthetics. Testing in the laboratory involved releasing groups of 50 gravid Ae. aegypti in walk-in rooms and assessing what percentage were caught in traps of different colors, with different trap cover sizes, and placed under lighter or darker locations. Two final trap models were mocked up and tested in homes for a week; one model was the top choice in both Iquitos and Lopburi. DISCUSSION: The community-based participatory process was essential for the development of novel traps that provided effective vector control, but also met the needs and concerns of community members.

Family stressors, home demands and responsibilities, coping resources, social connectedness, and Thai older adult health problems: examining gender variations.

OBJECTIVES: To examine gender variations in the linkages among family stressors, home demands and responsibilities, coping resources, social connectedness, and older adult health problems. METHODS: Data were collected from 3,800 elderly participants (1,654 men and 2,146 women) residing in Kanchanaburi province, Thailand. RESULTS: Findings indicated gender variations in the levels of these constructs and in the mediational pathways. Thai women indicated greater health problems than men. Emotional empathy was the central variable that linked financial strain, home demands and responsibilities, and older adult health problems through social connectedness. Financial strain (and negative life events for women) was associated with lowered coping self-efficacy and increased health problems. The model indicated greater strength in predicting female health problems. DISCUSSION: Findings support gender variations in the relationships between ecological factors and older adult health problems.

Sharing experiences and dilemmas of conducting focus group discussions on HIV and tuberculosis in resource-poor settings.

Focus group discussions (FGD) are gaining in popularity in research on HIV and tuberculosis (TB) internationally as researchers seek to understand the experiences, needs and perspectives of people living with TB and/or HIV as well as their carers within the community and health sector. Conducting FGDs in resource-poor settings with vulnerable participants who are living with diseases that are frequently stigmatised poses multiple challenges. Our approach in this discussion paper is to follow the research cycle to present the practical experience of research teams using FGDs in TB and HIV in resource-poor contexts in Africa and Asia in order to contribute to effective practice. The approach highlights dilemmas and shares effective practice for negotiating initial discussions with different communities, constructing sampling frames and samples, choosing a facilitator, encouraging discussion, ethics, translation, pitfalls and dissemination. We demonstrate the techniques and adaptations needed to ensure that FGDs provide rich, high-quality and policy-relevant data on the voices and perspectives of people living with HIV and TB, community groups and health workers within the challenges of resource-poor settings. In applying theory to develop good practice in FGDs across the research cycle, a critical and reflexive approach is needed.

Risk perception and condom-use among Thai youths: findings from Kanchanaburi Demographic Surveillance System site in Thailand.

Youths, aged 15-24 years, comprise a large fragment of the total population in Thailand, and unsafe sexual behaviours are increasing, nowadays, among young people. The study was conducted to explore the characteristics of youths and other conducive, facilitating and reinforcing factors associated with risk perception of sexually transmitted infections (STIs) among the study population. Data employed in this study were derived from the site of the Kanchanaburi Demographic Surveillance System of Thailand 2004 using a stratified systemic design. The study population was mainly young current condom-users aged 15-24 years, and cross-sectional analysis was done on this populace. The findings revealed that youths who fell into the single (unmarried) category having temporary partners were more likely to perceive the risks associated with STIs in relation to using condom. A greater proportion of unmarried youths was engaged in sexual activity before the age of 20 years and that condom-use was also inconsistent. Youths having temporary partners were more likely to perceive risk and reason for using a condom than when with their regular partner. Education played a significant role in risk perception of STIs. Risk perception was increasing with the increasing level of education. Other conducive and facilitating factors, such as household wealth, living in urban or semi-urban areas, and access to mass media such as television, also had a positive influence on risk perception. The odds ratio showed that condom-users who had indulgence in liquor were less likely to perceive the risk of STIs. Overall, socioeconomic status had a great influence on risk perception of STIs. Finally, youths exhibiting high-risk sexual behaviour need realistic risk assessments and positive ways of incorporating condom into their sexual lives.
