Diabetes, type 1

Detailed Description:

Despite intensively research in the field of hyperglycaemia and coronary heart disease in type 1 diabetes it is still not known in detail how hyperglycaemia leads to damage of the vessels.

The aims of the present proposal are therefore two-fold:

  1. To study in detail the progression of atherosclerosis (and micro vascular complications) in a well characterized cohort of type 1 diabetes with a long duration of the disease. This project will be a continuation of the Oslo study, a cohort started in 1982, with the last follow-up study in 1999/2000.
  2. To define factors responsible for the progression of coronary heart disease (and micro vascular complications) in this cohort.

Ages Eligible for Study:   40 Years to 70 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   Yes
Sampling Method:   Probability Sample
Study Population
This project will be a continuation of the previous cohort performed originally from 1982. The group or cohorts will be selected from primary care clinic.

The original criteria from 1982:

Inclusion Criteria:

  • Age 18-45 years
