根据我县第四次人口普查结果及对全县人口死亡原因之调查,年平均死亡率为600.12/10~5,肿瘤死亡率为132.2/10~5,其中胃癌死亡率为27.06/10~5,仅次于肝癌(34.31/10~5)而居弟二位,明显高于国内水平(23.86/10~5)和上海平均水平(22.64/10~5)。我们为了掌握全县胃癌的发病情况及可能的致病因素,自1990年6月至1992年
According to the results of the fourth census of the county and the investigation of the cause of death of the county’s population, the average annual mortality rate was 600.12/10~5, and the tumor mortality rate was 132.2/10~5. The mortality rate of gastric cancer was 27.06/10~5. Second only to hepatocellular carcinoma (34.31/10~5) and two younger brothers, it is significantly higher than the domestic level (23.86/10~5) and the Shanghai average (22.64/10~5).
