There is conflicting reports on the respiratory health effects of indoor risk factor exposure. The aim of this study was to assess the association of indoor environmental factors to pulmonary function in an adult population in Zunyi City of Southwest China.
Between July and Sep 2012, we conducted a cross-sectional survey of people aged ≥18 yr in 11 inner-city areas of Zunyi. Data on asthma and asthma-related symptoms and selected home environmental factors were assessed by questionnaire. Lung function measurements, including FVC, FEV, FEV/FVC and PEFR, were assessed and compared. Exposure to indoor and outdoor PM was monitored by measurement of PM emission relative concentration.
Cooking oil fumes, environmental tobacco smoke (ETS) and coal fuel use were associated with impaired lung function among adults in summer season (<0.05). Subjects exposed coal fuel combustion, cooking oil fumes, pest in kitchen, mosquito repellent, fluffy blanket, pets, visible mold in bedroom and ETS (active and passive smoking) tended to exhibit greater decreases in FVC, FEV and PEFR values compared with their non-exposed counterparts (<0.05). Median PM relative concentrations in kitchen, sleeping area and outdoor were 486.0cpm, 463.0cpm and 459.0cpm, respectively. PM relative concentration in indoor kitchen and sleeping area were significant higher than outdoor (<0.001).
A negative association between kitchen, sleeping area risk factors and ETS exposure and a reduction in lung function in summer was revealed in Zunyi.
关于室内危险因素暴露对呼吸健康的影响，存在相互矛盾的报道。本研究的目的是评估中国西南部遵义市成年人群中室内环境因素与肺功能之间的关联。
2012年7月至9月期间，我们对遵义市中心城区11个区域内年龄≥18岁的人群进行了横断面调查。通过问卷调查评估哮喘及哮喘相关症状的数据以及选定的家庭环境因素。对肺功能进行测量并比较，包括用力肺活量（FVC）、一秒用力呼气容积（FEV）、FEV/FVC和呼气峰值流速（PEFR）。通过测量颗粒物排放相对浓度监测室内和室外颗粒物暴露情况。
在夏季，食用油烟雾、环境烟草烟雾（ETS）和使用煤炭燃料与成年人肺功能受损相关（<0.05）。与未暴露者相比，暴露于煤炭燃料燃烧、食用油烟雾、厨房害虫、驱蚊剂、毛绒毯子、宠物、卧室可见霉菌以及ETS（主动和被动吸烟）的受试者，其FVC、FEV和PEFR值往往下降得更多（<0.05）。厨房、睡眠区域和室外的颗粒物相对浓度中位数分别为486.0cpm、463.0cpm和459.0cpm。室内厨房和睡眠区域的颗粒物相对浓度显著高于室外（<0.001）。
遵义市夏季揭示了厨房、睡眠区域危险因素及ETS暴露与肺功能下降之间存在负相关。
