中文摘要:
      本文介绍用“病例-对照”研究,对江苏省胃癌高发区流行因素进行分析。因素包括饮食种类和习惯、水源、经济生活和社会心理共50种,资料的单因素分析发现有16种因素与胃癌呈正相关联系(P<0.05~0.01);有10种因素与胃癌呈负相关联系(P<0.05~0.01)。多因素分析,首先用信息量分析而后用逐步回归和模糊聚类分析,发现主要入选因素依次为饮用河沟污染水、发病5年前人均口粮低、不食辣椒、生闷气、家族、胃癌史,发病5年前经济亏空及现金收入低等7个因素,复相关系数0.65627,常数项0.18601,F进=F出=17.2。全部资料用PC-1500机处理,数据用分段小程序输入解决该机内存不足。
英文摘要:
      Case-control study was used to analyze the factors of gastric cancer in high-incidence areas, Yangzhong and Jingjiang counties, Jiangsu Province. A total of 50 fnctors were examined, including the factors of diet, food hibit, water supply, socioeconomic status, psychological factors etc. Through the study of individual factors it was revealed that positive correlation existed in gastric cancer with 16 factors (P<0.05~0.01) and negative correlation with 10 factors (P<0.05~0.01). For multiple factor analysis, the data were initially processed with entropy function and then treated by stepwise regression fuzzy cluster. As a result, 7 factors were found to be associated with gastric cancer; they in order were, polluted drinking water, low food provision in the period of 5 years previous to diagnosis of cancer, non-ingestion of capsicum, low spirits, family history of gastric cancer and low income (in cash) or being in debt period of 5 years before onset of the illness (coefficient of multiple correlation = 0.06527, constant=0.18601, F.i= F.o=17.2). All of the data were processed with PC-1500 computer, and segmented program was adopted for input data so as to suit the computer's limited capacity of internal storage.
