本文就福建省及长乐县全死因回顾调查资料,应用Poisson分布原理分析胃癌死亡人群分布特征。福建省资料x~2=34.9330,P<0.001,不符合Poisson分布,提示全省有高低发区存在。长乐县X~2=0.9312,P>0.05,符合Poisson分布,即胃癌在该县呈高度分散状态,恶性肿瘤的地区分布和致癌因素分布相一致。 In this paper, the cause of death in Fujian Province and Changle County were retrospectively surveyed, and Poisson distribution principle was used to analyze the distribution characteristics of gastric cancer deaths. Fujian Province data x ~ 2 = 34.9330, P <0.001, does not meet the Poisson distribution, suggesting that there are high and low incidence areas throughout the province. Changle County X ~ 2 = 0.9312, P> 0.05, consistent with Poisson distribution, that gastric cancer was highly dispersed in the county, the regional distribution of malignant tumors and carcinogenic factors consistent.
