  Aims  Screening and prevention strategies for Type 2 diabetes require insight into the aetiological and potentially different risk factors leading to early impairments of fasting plasma glucose (FPG) and 2-h post-load plasma glucose (2hPG) levels. We studied whether risk factors predicting subtle elevations of FPG levels were different from those predicting elevations of 2hPG levels in men and women.

Methods  We used baseline and 5-year follow-up data from middle-aged men and women with normal glucose tolerance (NGT) at baseline in the Danish population-based Inter99 study (n = 3164). Anthropometric and non-anthropometric baseline predictors of the 5-year FPG and 2hPG levels were estimated in linear regression models stratified by gender.

Results  In men, but not in women, smoking and family history of diabetes predicted increased FPG levels, whereas high physical activity predicted a decline in 2hPG levels. Among the anthropometric variables, large waist circumference was the strongest predictor of increased FPG levels in men, whereas high body mass index (BMI) was the strongest predictor of increased FPG levels in women. In both men and women, BMI and waist circumference were equally strong in predicting 2hPG levels. Furthermore, short height predicted increased 2hPG levels in men, and short height and low hip circumference predicted increased 2hPG levels in women.

Conclusions  Risk factors that predict future FPG levels are different from those predicting future 2hPG levels. Furthermore, different risk factors predict glycaemic levels in men compared with women. These findings indicate that different aetiological pathways may lead to Type 2 diabetes in men and women.

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.
