背景：生物质燃料燃烧造成的室内空气污染 (IAP) 是一个全球性健康问题，估计每年导致 160 万人过早死亡。 目标：RESPIRE（室内污染和呼吸影响的随机暴露研究）危地马拉是有史以来第一个关于使用固体燃料对健康影响的随机对照试验。其目标是评估改良炉灶 (planchas) 对依赖木质燃料的农村人口的暴露和健康结果的影响。方法：在基线时和干预后定期向初始组 504 名女性（259 名随机分配到 planchas 组（平均（标准差）年龄 27.4 (7.2) 岁）和 245 名使用传统明火的女性（28.1 (7.1) 岁））询问有关症状的问题。每次访问时都会测量呼出气中的一氧化碳 (CO) 水平，这是近期暴露于生物质燃烧造成的空气污染的生物标志物。除了降低 IAP 水平外，plancha 还可以通过将工作姿势改为直立姿势来产生积极的健康影响。结果：发现眼睛不适、头痛和背痛的患病率很高。在随访期间，相对于使用明火的组，铁板组出现眼睛酸痛和头痛的几率大大降低（比值比 (OR) 0.18，95% 置信区间 (CI) 0.11 至 0.29 和 (OR) 0.63，95% CI 0.42 至 0.94）。干预试验中女性呼吸中 CO 的中位数显着低于对照组。结论：除了减少女性的不适之外，相当一部分女性所经历的症状的明显改善可能有助于 Planchas 获得接受和更广泛的使用。
Background: Indoor air pollution (IAP) from combustion of biomass fuels represents a global health problem, estimated to cause 1.6 million premature deaths annually.Aims: RESPIRE (Randomised Exposure Study of Pollution Indoors and Respiratory Effects) Guatemala is the first randomised controlled trial ever performed on health effects from solid fuel use. Its goal is to assess the effect of improved stoves (planchas) on exposure and health outcomes in a rural population reliant on wood fuel.Methods: Questions about symptoms were asked at baseline and periodically after the intervention, to an initial group of 504 women (259 randomly assigned to planchas (mean (standard deviation) age 27.4 (7.2) years) and 245 using traditional open fires (28.1 (7.1) years)). Levels of carbon monoxide (CO) in exhaled breath, a biomarker of recent exposure to air pollution from biomass combustion, were measured at each visit. In addition to reducing IAP levels, the plancha may also have a positive health effect by changing the working posture to an upright position.Results: A high prevalence of eye discomfort, headache and backache was found. The odds of having sore eyes and headache were substantially reduced in the plancha group relative to the group using open fires for the follow-up period (odds ratio (OR) 0.18, 95% confidence interval (CI) 0.11 to 0.29 and (OR) 0.63, 95% CI 0.42 to 0.94, respectively). Median CO in breath among women in the intervention trial was significantly lower than controls.Conclusion: In addition to reducing discomfort for women, tangible improvements in symptoms experienced by a substantial proportion of women may help to gain acceptance and wider use of planchas.
