Efficacy of water filters and training interventions in mitigating gastrointestinal symptoms in rural Honduras

Abstract

This study examines the interplay between poverty, economic instability, and the water crisis in Honduras, highlighting the role of water filter interventions and training in mitigating gastrointestinal (GI) symptoms. The aims are to assess the effectiveness of point-of-use (POU) water filters and the impact of additional training on health outcomes. Data on water filter usage and training were collected during medical brigades in rural Honduras in May 2023, where patients reported GI symptoms. Two hypotheses were tested: individuals with POU filters would experience fewer GI-related symptoms, and those receiving additional filter training would report even fewer symptoms. Results showed significant reductions in symptoms, including loss of appetite, vomiting, diarrhea, and stomachaches among water filter users. Initial training was effective, while additional training showed potential benefits but was less consistently significant. This study emphasizes the importance of both providing filters and comprehensive training to maximize health benefits and the need for sustained efforts in promoting effective water treatment practices. These results support the adoption of POU filters and training programs to improve public health outcomes in regions with prevalent waterborne diseases. Future research should focus on the long-term impacts of these interventions to guide more sustainable clean water interventions.
