Burning solid fuels to fulfill daily household energy needs results in chronic exposure to household air pollution (HAP), which is among the world's greatest health risks. This paper presents the results of a cross-sectional study of cookstove usage, fuel consumption, and indoor PM concentrations in rural and urban Honduran homes cooking with the Envirofit HM-5000 metal plancha stove (n = 32) as compared to control households using baseline cooking technologies (n = 33). Temperature-based stove usage measurements showed high HM-5000 acceptance, with significant displacement of the traditional cookstoves at both the urban (99%, P < .05) and rural study sites (75%, P < .05). However, longer-term usage data collected in peri-urban households showed that participants cooked on the HM-5000 more frequently during the 3-day monitoring period than during the following 3 weeks. Average indoor PM was 66% lower in HM-5000 households as compared to control households (P < .05). Lower indoor PM concentrations observed in participant homes as compared to control households, supported by high usage and traditional stove displacement, suggest the potential for the HM-5000 to yield health improvements in adopting Honduran households.
燃烧固体燃料来满足日常家庭能源需求会导致慢性暴露于家庭空气污染（HAP），这是世界上最大的健康风险之一。本文介绍了一项在农村和城市洪都拉斯家庭中使用 Envirofit HM-5000 金属烤盘炉（n=32）与使用基线烹饪技术的对照组家庭（n=33）进行的烹饪炉灶使用、燃料消耗和室内 PM 浓度的横断面研究结果。基于温度的炉灶使用测量显示 HM-5000 接受度很高，在城市（99%，P<.05）和农村研究点（75%，P<.05）都显著取代了传统炉灶。然而，在城市周边家庭收集的长期使用数据显示，参与者在 3 天监测期间比接下来的 3 周内更频繁地在 HM-5000 上做饭。与对照组家庭相比，HM-5000 家庭的室内 PM 平均降低了 66%（P<.05）。与对照组家庭相比，参与者家庭中观察到的室内 PM 浓度较低，这得益于高使用率和传统炉灶的替代，表明 HM-5000 有潜力改善洪都拉斯家庭的健康状况。
