应用１∶１配比病例对照研究方法对１４６对女性乳腺癌患者及其对照的危险因素进行了研究。配对Ｌｏｇｉｓｔｉｃ回归分析结果表明：既往有乳腺良性肿瘤史及常吃香肠是乳腺癌发生的主要危险因素；而蔬菜摄入量多及经常服用维生素类药物可明显降低发生乳腺癌的危险。另外，单因素分析结果还提示：腊肉摄入量多和长期被动吸烟等因素亦可明显增加乳腺癌发病的危险；而累积哺乳时间长则对乳腺癌发病有保护作用，Ｌｏｇｉｓｔｉｃ回归分析亦有类似结果。
The risk factors of 146 pairs of female breast cancer patients and their controls were studied using a 1:1 ratio case-control study. Paired Logistic regression analysis showed that previous history of benign breast tumors and frequent eating of sausages were the major risk factors for breast cancer; and the frequent intake of vitamins and vegetables may significantly reduce the risk of breast cancer. In addition, the results of univariate analysis also suggest that factors such as high intake of bacon and long-term passive smoking can also significantly increase the risk of breast cancer; long cumulative breast-feeding time has a protective effect on breast cancer, and logistic regression analysis is similar. result.
