This study analyses the relationship between migration and mortality for lung and stomach cancer, these diseases being those considered susceptible to changes in environmental conditions and individual habits that usually follow migration. Mortality rate of the province of birth was used as the index of risk related to migration. Data were analysed using the Poisson regression model for grouped data. Results indicate that migration determines modifications in the mortality rates of the migrant populations for the diseases under study. For lung cancer, the analysis showed a greater risk for migrants originating from areas with high rates and that migrants had a reduced risk in comparison with natives of Genoa. With regard to stomach cancer, the study revealed that migrants originating from high risk areas had higher relative risks than the Genoa natives, even if these were lower than expected when compared to the risks of the populations in the regions from which the migrants originated.
本研究分析了移民与肺癌和胃癌死亡率之间的关系，这些疾病被认为易受环境条件变化以及通常伴随移民而来的个人习惯改变的影响。将出生省份的死亡率用作与移民相关的风险指标。使用分组数据的泊松回归模型对数据进行分析。结果表明，移民会导致所研究疾病的移民人口死亡率发生变化。对于肺癌，分析显示来自高发病率地区的移民风险更高，且与热那亚本地人相比，移民的风险有所降低。关于胃癌，研究表明，来自高风险地区的移民的相对风险高于热那亚本地人，即便与移民来源地区的人群风险相比，这些风险低于预期。
