Cancer mortality in Italian migrants to Canada
Tumori
|February 28, 1994
Summary
Cancer mortality risks differed for Italian migrants in Canada compared to the Canadian-born population. Migrants showed higher risks for certain cancers like stomach and liver, while lower risks were seen for lung and prostate cancers.
Area of Science:
- Epidemiology
- Oncology
- Migration Studies
Background:
- Cancer mortality patterns among migrant populations are crucial for understanding environmental and lifestyle influences.
- Italian migrants represent a significant demographic in Canada, necessitating specific cancer risk analysis.
Purpose of the Study:
- To analyze cancer mortality rates in first-generation Italian migrants in Canada (1964-1985).
- To compare migrant cancer mortality with both the host Canadian population and the Italian population of origin.
Main Methods:
- Analysis of mortality data for 5,801 males and 3,267 females of Italian origin deceased between 1964-1985 in Canada.
- Comparative analysis at national (Italy) and regional (Southern Italy) levels.
- Comparison with Canada-born population and Italian population data.
Main Results:
- Italian migrants exhibited significantly higher risks for nasopharynx, stomach, liver, and gallbladder cancers compared to the Canada-born population.
- Lower cancer risks were observed in migrants for oral cavity, esophagus, colon, rectum, lung, breast, and prostate cancers.
- Findings align with Italy-Canada cancer mortality comparisons.
Conclusions:
- Cancer mortality profiles of Italian migrants in Canada reflect a complex interplay of genetic, environmental, and lifestyle factors.
- The observed patterns suggest a partial assimilation of cancer risk profiles towards the host country.
- Further research into specific risk factors is warranted to inform public health strategies.
