世界各地燃烧生物质燃料造成的家庭空气污染与哮喘、呼吸道感染和慢性肺部疾病有关。采用通风炉灶可显著减少接触HAP。然而，并发呼吸健康相关生活质量（HRQoL）的改善以前没有使用标准化问卷进行评估。在玻利维亚的一个农村社区进行干预研究，评估了木材烟雾暴露与呼吸系统HRQoL结果之间的关系。采用圣乔治呼吸问卷（SGRQ）对2009年和干预后1年的女性户主进行访谈，并对传统炉灶和带烟囱炉灶的室内一氧化碳（CO）水平进行分析。安装通风炉灶后，呼吸HRQoL显著改善，家庭CO水平显著降低。使用炉灶产生较低的室内CO值，并与SGRQ分数的提高呈正相关。这是首次使用标准化的呼吸系统HRQoL评估来确定通风炉灶对减少HAP的影响。这项初步研究利用SGRQ作为一种有价值的工具，可以分析这些健康影响与其他呼吸系统疾病状态的关系。
Household air pollution (HAP) from combustion of biomass fuels worldwide is linked to asthma, respiratory infections and chronic pulmonary diseases. Implementation of ventilated cookstoves significantly reduces exposure to HAP. However, improvements in concurrent respiratory health-related quality of life (HRQoL) have not been previously evaluated with a standardized questionnaire.The association between woodsmoke exposure and respiratory HRQoL outcomes was evaluated using an intervention study in a rural community in Bolivia. Indoor carbon monoxide (CO) levels from traditional stoves and from cookstoves with chimneys were analyzed alongside interview results of women heads-of-households using the St. George's Respiratory Questionnaire (SGRQ) in 2009 and 1-year post-intervention.Pronounced improvements in respiratory HRQoL and significant reductions of household CO levels followed installation of ventilated cookstoves. Stove implementation yielded lower indoor CO values and correlated positively with improved SGRQ scores.This is the first use of a standardized respiratory HRQoL assessment to determine the impact of ventilated cookstove implementation on reducing HAP. This preliminary study utilizes the SGRQ as a valuable tool enabling analysis of these health effects in relation to other respiratory disease states.
