Population mixing and childhood leukaemia and non-Hodgkins lymphoma in census wards in England and Wales 1966–87

摘要

We found an increased risk of childhood leukaemia with higher levels of inward migration, particularly from outside the region (rate ratio=1.9, 95%CI: 1.2–2.9, P<0.01). This significant effect was observed only in urban areas, although a marked but non-significant effect was seen in affluent, rural areas.British Journal of Cancer (2002) >86, 1411–1413. DOI: © 2002
