Population based studies of social inequalities in diabetes diagnosis, incidence, mortality and treatment (POSDIT)

The POSDIT study is a public health epidemiology and health service project targeting diabetes. The overall purpose is comprehensive analysis of time trends and social inequality in undiagnosed diabetes, incidence of type 2 diabetes across the lifespan, treatment and mortality among patients with type 2 diabetes in Norway.

News from 2022:
During 2022, a paper from the HUNT study on undiagnosed diabetes has been published.

We have participated in a multi-country project organized by the Baker Heart and Diabetes Institute in Australia. A paper on mortality trends in type 1 diabetes (without data from Norway) has been published in the Diabetologia. A paper on all-cause mortality and another on lifetime risk, life expectancy, and years of life lost to type 2 diabetes in type 2 diabetes have been published in the Lancet Diabetes and Endocrinology in 2022.

We have collaborated with the IDF Diabetes Atlas in the group on undiagnosed diabetes.
