于１９９１年４月至１９９４年１２月在沈阳市区内进行了对终身非吸烟女性肺癌危险因素调查的病例对照研究，共选调了新诊断的非吸烟原发性肺癌病例１６６例及相应数量、配比年龄与性别的一般人群为对照，病理组织细胞型以腺癌为主．占６２．２％．其次为小细胞癌．占１７．１％，鳞癌占１４．６％，其他为６．１％，用Ｍｅｎｔａｌ－Ｈａｅｎｓｘｌ法与多因素Ｌｏｇｉｓｔｉｃ回归模型对资料进行分析，其调整ＯＲ与９５％Ｃｌ值：烹饪油烟暴露为４．１１（２．１４～７．８９）．肺部疾病史为２．９８（１．３０～６．４１），亲属患病史为２．９８（１．３０～６．４１），煤烟在单因素分析中对肺癌发生有显著意义．但未进入多因素分析模型。被动吸烟与烧炕史诸因素均未见与肺癌的发生有联系．
A case-control study of risk factors for lung cancer in lifelong non-smoking women was conducted in Shenyang City from April 1991 to December 1994. A total of 166 newly diagnosed non-smoking primary lung cancer cases were selected and their corresponding numbers were Compared with the general population with age and sex, the histopathological cell type is mainly adenocarcinoma. Accounting for 62.2%. Followed by small cell carcinoma. 17.1%, 14.6% of squamous cell carcinomas, and 6.1% of others. Data were analyzed using the Mental-Haensxl method and a multivariate Logistic regression model, which adjusted OR and 95% Cl values: cooking fumes were exposed to 4.11 (2.14 to 7.89). The history of lung disease was 2.98 (1.30-6.41), and the relative history of the disease was 2.98 (1.30-6.41). Soot had a significant effect on lung cancer in univariate analysis. But did not enter the multi-factor analysis model. The factors of passive smoking and burning history were not related to the occurrence of lung cancer.
