目的通过因子分析观察影响食管癌发病因素的公因子。方法对472例食管癌患者,调查了可能影响食管癌发病的36项,对单因素分析的有意义的34项因素进行了初始因子分析和方差最大旋转。结果34项影响因素间存在6个主要公因子,其中,第一公因子上因子载荷较大的有喜烫食、烫茶、干硬食物、口味重、热食且快、吸烟、饮酒、及家庭关系、脾气性格、家族史,第二公因子上因子载荷较大的有BM I、文化程度、职业、经济收入,第三公因子上因子载荷较大的有居住地形、饮水污染,第四公因子上因子载荷较大的有煎饼、腌制品、醋、发霉食物,第五公因子上因子载荷较大的有饮茶、蔬菜、水果、豆制品、姜、大蒜,第六公因子上因子载荷较大的有消化道病史、慢性食管炎、咽炎、口腔溃疡、龋齿。结论食管癌高发主要与不良生活嗜好、环境污染、食管癌家族史及消化道疾病史、霉变食物有较大关系。
Objective To observe the common factors affecting the incidence of esophageal cancer by factor analysis. Methods A total of 362 patients with esophageal cancer were enrolled and 36 subjects with possible esophageal cancer incidence were investigated. Initial factor analysis and maximum variance rotation were performed on 34 significant factors of univariate analysis. Results There were 6 major common factors among the 34 influential factors. Among them, the first common factor had more factors such as hi-hot, hot tea, hard and dry food, heavy taste, hot food and fast, smoking, drinking and family Relationship, temper personality, family history, the second factor of a larger factor load BM I, degree of education, occupation, economic income, the third factor on a larger factor load residential terrain, drinking water pollution, the fourth public Factors on the larger factors are pancakes, pickles, vinegar, moldy food, the fifth factor on a larger factor load tea, vegetables, fruits, soy products, ginger, garlic, factor on the sixth factor A larger load of gastrointestinal history, chronic esophagitis, pharyngitis, oral ulcers, dental caries. Conclusions The high risk of esophageal cancer is mainly related to bad habits, environmental pollution, family history of esophageal cancer, history of gastrointestinal diseases and moldy food.
