Purpose
The main purpose of this study is to investigate progression of late complications of diabetes during the last ten years in a well characterized cohort of type 1 diabetes with a long duration of the disease, and to define factors responsible for the progression of late complications.

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:
- 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.
- To define factors responsible for the progression of coronary heart disease (and micro vascular complications) in this cohort.
Eligibility| Ages Eligible for Study: | 40 Years to 70 Years |
| Genders Eligible for Study: | Both |
| Accepts Healthy Volunteers: | Yes |
| Sampling Method: | Probability Sample |
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:
