  Background and aim  Most studies show that diabetes increases with migration and urbanization. Previous studies from Greenland have shown inconsistent associations between cardiovascular risk and urbanization. Thus, the aim was to study the association between diabetes and urbanization among Greenland Inuit.

Methods  A total of 3089 adult Inuit aged 18 years and older participated in a geographically representative, population-based study ‘Inuit Health in Transition Study’. The examination included a 75 g oral glucose tolerance test and anthropometric measurements. Information on socio-demographic characteristic and health behaviour was obtained by interview or questionnaire. The participants were categorized according to degree of urbanization into three groups based on current place of residence: (1) participants living in towns (> 2000 inhabitants), (2) participants living in small towns (< 2000 inhabitants) and (3) participants living in villages (< 500 inhabitants).

Results  The total prevalence of diabetes was 9% of which 79% were previously unknown. Nine per cent had impaired glucose tolerance and 19% had impaired fasting glycaemia (IFG). Compared with towns, odds rations (ORs) for diabetes and impaired fasting glycaemia were higher in small towns [ORdiabetes = 1.5 (1.0-2.3), ORIFG = 1.9 (1.2-2.3)] and villages [ORdiabetes = 1.2 (0.8-1.9), ORIFG = 1.3 (0.9-2.0)], whereas no association was seen for impaired glucose tolerance. The inverse association between urbanization and diabetes and impaired fasting glycaemia persisted after adjustment for relevant confounders.

Conclusion  Diabetes and impaired fasting glycaemia decreased with urbanization contrary to the results of most studies. It appears that Greenland Inuit follow the pattern usually observed in industrialized countries with the highest risk of diabetes in the lower socio-economic groups.

Aims

Diabetic foot disease and amputations severely reduce quality of life and have major economic consequences. The aim of this study was to estimate time trends in the incidence of lower-extremity amputations in Danish people with diabetes.

Methods

We studied major and minor lower-extremity amputations from 2000 to 2011 among 11 332 people with diabetes from the Steno Diabetes Center. Amputations were identified by linkage of the electronic medical system with the National Patient Registry. Sex-specific incidence rates of amputations by age, diabetes duration, calendar time and diabetes type were modelled by Poisson regression.

Results

From 2000 to 2011, 384 incident lower-extremity amputations (205 major, 179 minor) occurred during 100 495 years of patient follow-up. From 2000 to 2011, the incidence of all lower-extremity amputations decreased by 87.5% among men and 47.4% among women with Type 1 diabetes and by 83.3% among men and 79.1% among women with Type 2 diabetes (P < 0.001). In particular, there was a decline in major lower-extremity amputations. In 2011, the incidence rates of major lower-extremity amputations were 0.25 (95% CI 0.07-0.82) among men and 0.21 (95% CI 0.06-0.71) among women per 1000 patient-years at age 50 years and 0.56 (95% CI 0.18-1.89) among men and 0.41 (95% CI 0.16-1.09) among women per 1000 patient-years at age 70 years. No significant change in incidence of minor amputations was observed.

Conclusion

The incidence of major lower-extremity amputations reduced significantly from 2000 to 2011 in Danish people with diabetes followed at a diabetes specialist centre.
