Elevated indoor air pollution levels due to the burning of biomass in developing countries are well established. Few studies have quantitatively assessed air pollution levels of improved cookstoves and examined these measures in relation to health effects. We conducted a cross-sectional survey among 79 Honduran women cooking with traditional or improved cookstoves. Carbon monoxide and fine particulate matter (PM(2.5)) levels were assessed via indoor and personal monitoring. Pulmonary function and respiratory symptoms were ascertained. Finger-stick blood spot samples were collected to measure C-reactive protein (CRP) concentrations. The use of improved stoves was associated with 63% lower levels of personal PM(2.5), 73% lower levels of indoor PM(2.5), and 87% lower levels of indoor carbon monoxide as compared to traditional stoves. Women using traditional stoves reported symptoms more frequently than those using improved stoves. There was no evidence of associations between cookstove type or air quality measures with lung function or CRP.
发展中国家因燃烧生物质而导致室内空气污染水平升高已是公认的事实。但很少有研究定量评估改良炉灶的空气污染水平，并研究这些措施与健康影响之间的关系。我们在 79 名使用传统炉灶或改良炉灶的洪都拉斯妇女中进行了一项横断面调查。通过室内和个人监测评估了一氧化碳和细颗粒物（PM2.5）水平。测定了肺功能和呼吸症状。采集指尖血样以测量 C 反应蛋白（CRP）浓度。与传统炉灶相比，使用改良炉灶可使个人 PM2.5 水平降低 63%，室内 PM2.5 水平降低 73%，室内一氧化碳水平降低 87%。使用传统炉灶的妇女比使用改良炉灶的妇女更频繁地报告有症状。改良炉灶类型或空气质量测量与肺功能或 CRP 之间没有关联的证据。
