In the first part of the study the prevalence and incidence of diagnosed Type 2 diabetes among adult rural populations of southern, central and northern areas of the Krasnoyarsk region of Siberia is compared. The six-year mean incidence of diabetes in the southern area was 0.86 per 1000 (95 CI: 0.66-1.06), in the central area this incidence was 0.79 (0.57-1.01). In contrast, in the northern area the mean Type 2 incidence among indigenous population was 0.16 per 1000 (0-0.43) and among aliens it was 0.38 (0.22-0.54). The age-standardised Type 2 diabetes prevalence in the population of southern and central areas were 10.23 (9.55-10.-92) and 10.77 (9.99-11.55), respectively. In the northern area among aliens it was 8.98 (8.18-9.78) and among indigenous peoples only 2.54 per 1000 (1.46-3.62). The second part of this study consists of a population based survey to determine the prevalence rate of Type 2 diabetes among 596 Evenks and 306 alien inhabitants in Evenkia (82 eligible participants of Baikit district). No cases of glucose intolerance were found among Evenks in this study and one case of Type 2 diabetes was confirmed among aliens (prevalence rate 3.27 per 1000). These data indicate that Type 2 diabetes is still rare among northern indigenous populations of Siberia and that diabetes in northern alien populations is less prevalent than among peoples of central and southern areas of Siberia.
