本文通过对烟、酒、茶等嗜好因素与肝癌死亡率的相关分析和病例对照多元条件Ｌｏｇｉｓｔｉｃ回归分析，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－０．９８和－０．９２，饮酒率与之存在一定程度的正相关。启东肝癌重要的危险因素除ＨＢＶ感染外，饮酒因素亦是危险因素之一，其ＯＲ值达３．４７；而饮茶可能为一保护因素。上述结果经多元模型拟合，认为是比较可信的。
This article analyzes the correlation between smoking factors such as tobacco, alcohol, tea, and hepatocellular carcinoma mortality and case-control multivariate logistic regression analysis. It shows that tea drinking rate is significantly negatively correlated with liver cancer and gastrointestinal cancer, and the correlation coefficients are -0. For .98 and -0.92, there was a positive correlation between alcohol consumption and a certain degree. Among the important risk factors for liver cancer in Qidong, in addition to HBV infection, alcohol intake is also one of the risk factors, with an OR of 3.47; drinking tea may be a protective factor. The above results are fitted by a multivariate model and are considered to be more reliable.
