世界上一半的人口仍然依靠固体燃料来满足烹饪和空间取暖的能源需求，导致家庭空气污染严重，对人类健康和环境产生不利影响。一项横断面队列研究进行了调查之间的任何关联：(1)HAP指标（PM2.5，肺沉积表面积（LDSA）和CO）；(2)一系列家庭和社会人口特征；(3)印度南部农村每天暴露于生物质炉灶排放物的妇女和儿童的肺功能。在96个家庭的厨房内收集HAP测量数据，并对每个入组家庭的妇女和儿童进行肺功能测试。详细的调查问卷包括家庭特征、健康史和各种社会人口参数。采用简单的线性和逻辑回归分析来检验HAP指标、肺功能和所有家庭/社会人口变量之间可能存在的关联。8%的母亲和9%的儿童存在阻塞性肺缺陷（FVC≥正常下限（LLN）和FEV1/FVC<LLN）， 17%的母亲和15%的儿童存在限制性肺缺陷（FVC<LLN和FEV1/FVC≥LLN）。首次在此类流行病学研究中观察到LDSA与肺功能之间的正相关，表明与PM2.5相比，LDSA是评估PM对肺功能影响的更好指标。HAP与儿童肺功能亚正常中度相关。结果强调需要超越基于质量的PM指标来全面评估HAP与肺功能之间的关系。固体燃料炉灶的排放物对人类健康和环境产生不利影响。一项横断面队列研究调查了印度南部农村使用生物质炉灶家庭中妇女和儿童的HAP指标（PM2.5、肺沉积表面积（LDSA）和CO）、家庭和社会人口特征以及肺功能之间的关系。LDSA与肺功能之间的正相关（首次纳入此类流行病学研究）表明，与PM2.5相比，LDSA是评估PM对肺功能影响的更好指标。
Half of the world’s population still relies on solid fuels to fulfill its energy needs for cooking and space heating, leading to high levels of household air pollution (HAP), adversely affecting human health and the environment. A cross-sectional cohort study was conducted to investigate any associations between: (1) HAP metrics (PM2.5, lung-deposited surface area (LDSA), and CO); (2) a range of household and socio-demographic characteristics; and (3) lung function for women and children exposed daily to biomass cookstove emissions, in rural Southern India. HAP measurements were collected inside the kitchen of 96 households, and pulmonary function tests were performed for the women and child in each enrolled household. Detailed questionnaires captured household characteristics, health histories, and various socio-demographic parameters. Simple linear and logistic regression analysis was performed to examine possible associations between the HAP metrics, lung function, and all household / socio-demographic variables. Obstructive lung defects (FVC≥lower limit of normal (LLN) and FEV1/FVC<LLN) were found in 8% of mothers and 9% of children, and restrictive defects (FVC<LLN and FEV1/FVC≥LLN) were found in 17% of mothers and 15% of children. A positive association between LDSA, included for the first time in this type of epidemiological study, and lung function was observed, indicating LDSA is a superior metric compared to PM2.5 to assess effects of PM on lung function. HAP demonstrated a moderate association with subnormal lung function in children. The results emphasize the need to look beyond mass-based PM metrics to fully assess the association between HAP and lung-function. Emissions from solid fuel cookstoves adversely affects human health and the environment. A cross-sectional cohort study investigated associations between HAP metrics (PM2.5, lung-deposited surface area (LDSA), and CO), household and socio-demographic characteristics, and lung function for women and children in households using biomass cookstove, in rural Southern India. A positive association between LDSA, included for the first time in this type of epidemiological study, and lung function indicates LDSA is a superior metric compared to PM2.5 to assess effects of PM on lung function.
