Hypothesis
Is there an increased risk of childhood acute leukaemia in isolated French communes with high inter-census population movements?
Conclusion
The study found that higher proportions of in-migrants in isolated communes were associated with increased population changes and a marked risk of childhood leukaemia.
Supporting Evidence
- The study evidenced an increased risk of childhood acute leukaemia in isolated communes with high population movements.
- Isolated communes with less than 8% in-migrants had a 2.3% population increase, while those with 14% or more saw a 4.1% increase.
- A marked increase in leukaemia risk was found in communes with the highest average migration distances.
Takeaway
If a lot of people move into a small town, it might be linked to more kids getting sick with leukaemia, especially if those people come from far away.
Methodology
The study analyzed population changes and in-migration rates in isolated communes in France between 1990 and 1999.
Limitations
The study did not establish a direct causal relationship between in-migration and childhood leukaemia risk.
