Utilizing Mixed Methods Community-Based Participatory Research to Improve Environmental Health and Quality of Life Outcomes in Rural Rwanda

Abstract

Background: Health risks associated with burning biomass and stress on forests caused by firewood demand have necessitated improved cookstove programs. This study aimed to introduce and assess the functionality and impact of an intervention rocket cookstove in a rural Rwandan village.
 Method: This study used a mixed-method community-based participatory research (MMCBPR) design to introduce and test an intervention rocket cookstove. Interviews and focus groups were conducted to gather participants’ perspectives on using stoves and their perceived impact on quality of life. This study occurred over five years and culminated in three distinct phases.
 Results: Quantitative data showed that rocket stoves reduced firewood consumption by 30%–50% compared to traditional cooking methods. In addition, the qualitative data indicated widespread acceptance of the intervention concomitant with improved environmental health and quality of life outcomes. Participants reported improved health due to reduced smoke exposure, eye irritation, headaches, and an improved capacity for savings.
 Conclusion: The longitudinal nature of this study provides insight into the complexities of MMCBPR in the Global South. The findings show that small interventions, such as an improved cookstove, can improve the quality of life of individuals in marginalized communities if researchers are willing to invest the time that MMCBPR requires. Suggestions for future studies, especially for researchers seeking to expand MMCBPR beyond the boundaries of public health in North America, are discussed.
