本文通过对烟、酒、茶等因素与肝癌死亡率的相关分析及病例对照研究，探讨了嗜好因素与肝癌的病因学联系。结果显示，饮茶率与肝癌、消化道癌有极显著的负相关，相关系数分别为一０．９８及一０．９２；饮酒率与肝癌和消化道癌存在一定程度的正相关。病例对照的多元Ｌｏｇｉｓｔｉｃ回归分析表明，启东肝癌重要的危险因素除ＨＢＶ感染外，饮酒因素（指常饮白酒、开始饮酒年龄小于１６岁）也是危险因素之一，ＯＲ值可达３．４７；而饮茶史为一保护因素，ＯＲ值为０．６２。此外，本文所建立的两个多元模型拟合度均较优，说明上述结果是比较可信的。
In this paper, through the correlation analysis of tobacco, alcohol, tea and other factors and liver cancer mortality, and case-control study, the etiology relationship between the factors of hedonic and liver cancer is discussed. The results showed that tea drinking rate was significantly negatively correlated with liver cancer and digestive tract cancer, and the correlation coefficients were 0.98 and 0.92 respectively. There was a positive correlation between drinking rate and liver cancer and gastrointestinal cancer. Case-control multivariate logistic regression analysis showed that in addition to HBV infection, important risk factors for liver cancer in Qidong were related to alcohol intake (referring to Changyin Liquor and starting drinking at a young age of 16 years) as one of the risk factors, with an OR of 3.47; The history of tea drinking was a protective factor with an OR of 0.62. In addition, the fitting degree of the two multivariate models established in this paper are all excellent, indicating that the above results are more reliable.
