对安徽、河北、河南、吉林、江苏、山西、湖南和浙江8省574县、旗居民胃癌调整死亡率与食盐人均消费量两组变量进行相关分析。结果表明男性两组变量的相关系数为0.349(P<0.01),女性两组变量相关系数为0.309(P<0.01)。各省男性和女性两组变量相关系数在0.206和0.455之间,但其差别并无显著意义。从而提示胃癌发生与食盐消费量关联。
Correlation analysis was made between the adjusted rates of gastric cancer mortality and salt consumption in 574 counties in Anhui, Hebei, Henan, Jilin, Jiangsu, Shanxi, Hunan and Zhejiang provinces. The results showed that the correlation coefficient between the two groups was 0.349 (P <0.01), and the correlation coefficient between the two groups was 0.309 (P <0.01). The correlation coefficient between the two groups was 0.206 and 0.455, but the difference was not significant. Thus prompted the occurrence of gastric cancer and salt consumption associated.
