Hypothesis
Does the place of birth influence stomach cancer mortality more than the place of death?
Conclusion
Stomach cancer mortality is more closely related to the county of birth than the county of death.
Supporting Evidence
- Proportional mortality from stomach cancer was more closely related to county of birth than of death.
- Among non-migrants, PMRs for stomach cancer ranged from 67 to 159 across different counties.
- Most migrations were from high to low stomach cancer mortality areas.
Takeaway
Where you are born affects your chances of getting stomach cancer more than where you live later.
Methodology
The study analyzed mortality data from death certificates, comparing proportional mortality ratios for stomach cancer among migrants and non-migrants.
Limitations
The study lacked appropriate population denominators and information about where subjects lived between birth and death.
Participant Demographics
The study included 749,035 men and women who died between 1969 and 1972.
