A Logistic Regression Analysis of Risk Factors In Relation to Women Breast Cancer

女性乳腺癌危险因素研究资料采集于广州，韶关，肇庆等八个医院。按１∶２配对设计总共收集了１２５个病例一对照组作回顾性调查。经条件Ｌｏｇｉｓｔｉｃ回归．分析得：保护因子有喝茶习惯，ＯＲ＝０．３９１３；危险因子有精神创伤，ＯＲ＝３．４３３８，乳腺炎史，ＯＲ＝３．４０９９，被动吸烟，ＯＲ＝２．０７９６，平均摄油量，ＯＲ＝３．１７７３，流产，ＯＲ＝１．３５４４，癌症家族史，ＯＲ＝５．６７９７。

The data were collected in 8 hospitals in Guangzhou, Shaoguan and Zhaoqing of Guangdong Province. Altogether 125 matched sets were investigated in retrospect. There were one case matched two controls in every set.The data were analyzed by using multiple conditional Logistic regression model.The results suggested that habit of drinking-tea OR=0. 3913 was regsrded as a protective factor and psychic trauma OR=3. 4338, history of mastitis OR=3. 4099, passive smoking OR=2. 0796, average of oil intake OR=3. 1773, abortion OR=1. 3544 and family history of cancer OR=5.6797 were regarded as risk factors.
