[Mortality in type 2 diabetes changes over time in immigrants to Sweden].

Non-western immigrants have a higher prevalence of type 2 diabetes and earlier onset than non-immigrant Swedes. In this 10-year follow-up including all people in Sweden diagnosed with type 2 diabetes from 2006 onwards (i.e. prescribed glucose lowering medication for type 2 diabetes), the total and cause-specific mortality of first-generation immigrants with type 2 diabetes is lower than in non-immigrant Swedes. However, the higher survival rates in first generation immigrants disappear over time and second-generation immigrants rather show higher all-cause mortality rates than native Swedes. Contributing causes may be related to acculturation to the western lifestyle and gene environment interactions but remains to be further investigated.
