The association between indoor smoke exposure due to traditional baking (baking homemade bread) and anthracosis has rarely been investigated. The aim of the present study is to quantify such association among the Iranian population. A hospital based case-control study was carried out on 83 anthracotic cases and 155 controls (83 individuals with non-anthracotic pulmonary disorders from the pulmonary ward and 72 persons from the surgical ward without any known pulmonary disorders). The interview was performed using the "American Thoracic Society" questionnaire, comprising demographic information, occupational history, cigarette smoking, and indoor smoke exposure due to traditional baking. Multivariate analysis was performed by logistic regression. Comparison between cases and pulmonary ward controls showed that only the association between indoor smoke exposure due to traditional baking and anthracosis in women was statistically significant (OR: 4.30, 95% CI: 1.31 to 14.10). This was concluded after adjusting for other risk factors such as occupational exposure to dust, age, and education. When surgical ward controls were considered as control, after controlling for the significant risk factors, we found a significant relationship between indoor smoke exposure due to traditional baking and anthracosis (OR: 3.35, 95% CI: 1.49 to 7.55). Based on the findings from this study, it is concluded that there is an association between indoor smoke exposure and anthracosis. Women are significantly more susceptible to anthracosis than men are when exposed to smoke exposure.
传统烘焙（自制面包烘焙）导致的室内烟雾暴露与煤工尘肺之间的关联鲜有研究。本研究旨在量化伊朗人群中的这种关联。在一家医院开展了一项病例对照研究，研究对象为83例煤工尘肺病例和155名对照者（83名来自肺病科病房的非煤工尘肺肺部疾病患者以及72名来自外科病房且无任何已知肺部疾病的人员）。采用“美国胸科学会”问卷进行访谈，问卷内容包括人口统计学信息、职业史、吸烟情况以及传统烘焙导致的室内烟雾暴露情况。通过逻辑回归进行多变量分析。病例组与肺病科病房对照组之间的比较显示，仅女性中传统烘焙导致的室内烟雾暴露与煤工尘肺之间的关联具有统计学意义（比值比：4.30，95%置信区间：1.31至14.10）。这是在对职业粉尘暴露、年龄和教育程度等其他风险因素进行校正后得出的结论。当将外科病房对照组视为对照时，在对显著风险因素进行控制后，我们发现传统烘焙导致的室内烟雾暴露与煤工尘肺之间存在显著关联（比值比：3.35，95%置信区间：1.49至7.55）。基于本研究结果，得出室内烟雾暴露与煤工尘肺之间存在关联的结论。女性在接触烟雾暴露时比男性更易患煤工尘肺。
