Hypothesis
How does the duration of residence in Australia affect cancer mortality rates among East and Southeast Asian migrants?
Conclusion
Asian migrants in Australia have significantly higher risks of dying from certain cancers, particularly nasopharyngeal and liver cancers, which decrease over time.
Supporting Evidence
- Asian migrants had a 30-fold higher risk of dying from nasopharyngeal cancer in the first 2 decades of residence.
- The risk of dying from liver cancer was 12-fold higher in the first 2 decades for Asian migrants.
- The risk for colorectal, breast, and prostate cancers converged towards Australian-born levels after 30 years.
Takeaway
People from East and Southeast Asia who move to Australia are more likely to die from specific cancers when they first arrive, but this risk decreases the longer they live there.
Methodology
The study used routinely collected data and a case-control approach to analyze cancer mortality based on duration of residence.
Participant Demographics
Migrants born in East or Southeast Asia living in New South Wales, Australia.
