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.
全球范围内，生物质燃料燃烧产生的家庭空气污染（HAP）与哮喘、呼吸道感染及慢性肺部疾病相关。使用通风炉灶可显著减少HAP暴露。然而，此前尚未通过标准化问卷评估其对同时期呼吸健康相关生活质量（HRQoL）的改善情况。
在玻利维亚的一个农村社区开展干预研究，评估木柴烟雾暴露与呼吸HRQoL结果之间的关联。分析了传统炉灶和带烟囱炉灶的室内一氧化碳（CO）水平，并结合2009年及干预后1年使用圣乔治呼吸问卷（SGRQ）对家庭女性户主进行访谈的结果。
安装通风炉灶后，呼吸HRQoL有显著改善，家庭CO水平显著降低。炉灶的使用使室内CO值降低，且与SGRQ得分的改善呈正相关。
这是首次使用标准化呼吸HRQoL评估来确定通风炉灶的使用对减少HAP的影响。这项初步研究将SGRQ作为一种有价值的工具，能够分析这些健康影响与其他呼吸道疾病状态的关系。
