One third of the world's population use biomass fuel like wood, dung or charcoal for cooking. The smoke from these organic materials increases the incidence of respiratory illness including chronic obstructive pulmonary disease and lung cancer.
To evaluate forced expiratory lung volumes in asymptomatic women previously exposed to biomass fuel smoke.
The study was done in 74 healthy asymptomatic women divided into two age matched groups of 37 each. Pulmonary function tests (PFT) were assessed by computerised spirometry and statistical comparisons done on women using biomass fuel (study group) and women using other sources of fuel (LPG/ electric stove) for cooking (control group).
The PFT results showed significant reduction in forced expiratory lung volumes like Forced Vital Capacity (FVC), Forced Expiratory Volume in 1(st) sec (FEV1), Forced Expiratory Flow between 25-75% (FEF 25-75%) and Forced Expiratory Volume percentage (FEV1%) in biomass fuel users as compared to those not exposed to biomass fuel smoke.
The results of this study suggest that biomass fuel smoke may produce definite impairment in lung function, especially with regard to the smaller airways.
世界上三分之一的人口使用木材、粪便或木炭等生物质燃料做饭。这些有机材料产生的烟雾会增加包括慢性阻塞性肺疾病和肺癌在内的呼吸道疾病的发病率。
评估既往接触过生物质燃料烟雾的无症状女性的用力呼气肺容积。
该研究对74名健康无症状女性进行，分为两个年龄匹配组，每组37人。通过计算机化肺量计评估肺功能测试（PFT），并对使用生物质燃料的女性（研究组）和使用其他燃料来源（液化石油气/电炉）做饭的女性（对照组）进行统计比较。
与未接触生物质燃料烟雾的女性相比，PFT结果显示，生物质燃料使用者的用力呼气肺容积，如用力肺活量（FVC）、第1秒用力呼气量（FEV1）、25%-75%用力呼气流量（FEF 25-75%）和用力呼气量百分比（FEV1%）显著降低。
本研究结果表明，生物质燃料烟雾可能会对肺功能产生明确损害，尤其是对较小气道。
