本文对１９７６～１９９６年宣威肺癌病因学干预试验研究数据库中男性人群的原始记录进行了分析。运用状态风险分析理论，选择生活燃料（包括改炉改灶）、吸烟和慢性支气管炎病史为伴随变量，建立了宣威男性肺癌的危险状态分类模型。该模型可对人群及个体患肺癌危险度进行评价，有助于确定肺癌高危人群和高危个体，为指导当地肺癌的预防提供科学依据。
This article analyzes the original records of the male population in the database of the Xuanwei Lung Cancer Etiology Intervention Study from 1976 to 1996. Using the theory of state risk analysis, we selected the life fuel (including changing the stove and changing stoves), the history of smoking and chronic bronchitis as concomitant variables, and established a classification model for dangerous states of male lung cancer in Xuanwei. The model can evaluate the risk of lung cancer in populations and individuals and help determine the high-risk groups and high-risk individuals of lung cancer, and provide scientific basis for the prevention of local lung cancer prevention.
