Pulmonary function studies were carried out in 3318 healthy, nonsmoking asymptomatic housewives to evaluate the role of different cooking fuels in domestic use. The women used four different types of cooking fuels: biomass fuel, liquified petroleum gas (LPG), kerosene used in stoves, and a combination of two or more of these (mixed). Four parameters of ventilatory function (FVC, FEV1, PEFR and MMEF) were evaluated. A positive correlation was observed between all these parameters except PEFR with that of height, but a negative correlation was observed between the age, duration of cooking and exposure index. Mixed fuels and biomass fuels affected FVC values (F = 6.39, p = 0.0003) more adversely. Similar trend was observed for FEV1 also. Users of biomass fuel had the lowest mean value for PEFR. Small airways function represented by MMEF was the lowest in users of kerosene. In users of mixed fuels, there was a decline in FVC, FEV1 and PEFR, as the exposure increased. Thus, it is concluded that, mixed fuel has more deleterious effects on pulmonary function than other fuels.
对3318名健康、不吸烟的无症状家庭主妇进行了肺功能研究，以评估不同家用烹饪燃料的作用。这些女性使用四种不同类型的烹饪燃料：生物质燃料、液化石油气（LPG）、炉灶中使用的煤油以及其中两种或更多种的组合（混合燃料）。评估了通气功能的四个参数（用力肺活量（FVC）、第一秒用力呼气容积（FEV1）、呼气峰值流速（PEFR）和最大呼气中期流速（MMEF））。除PEFR外，所有这些参数与身高均呈正相关，但与年龄、烹饪时间和暴露指数呈负相关。混合燃料和生物质燃料对FVC值（F = 6.39，p = 0.0003）的不利影响更大。FEV1也观察到类似趋势。生物质燃料使用者的PEFR平均值最低。以MMEF表示的小气道功能在煤油使用者中最低。在混合燃料使用者中，随着暴露增加，FVC、FEV1和PEFR均下降。因此，得出结论，混合燃料对肺功能的有害影响比其他燃料更大。
