The incidence of type 1 diabetes is increasing in France. A recent cross sectional study has shown that in France, only 15% of children and 26% of adults had HbA1c<7%. Adolescents seem to need particularly a better metabolic control.

Working Hypothesis:

We hypothesized that a stricter control of glycaemia by nurse-counselling could probably improve metabolic control in adolescents with type 1 diabetes.


To show that nurse-counselling may improve levels of patient satisfaction.


The main criterion is the patient acceptance of diabetes measured by an analogical visual scale rated from 0 (I cope very well with my diabetes, I cope very badly with my diabetes) to 10 cm. The scale will be measured every quarter within 12 months follow-up. We wish to improve patient's appreciation by 10 mm, near to "I cope very well with my diabetes".

This is a randomised parallel group study with 36 subjects in each group. During the follow-up, the "routine follow-up" group will continue its routine care. The "complementary follow-up" group will be called by nurses every 15 days and consult monthly. HbA1c is the secondary criterion and will be measured every 3 months.

The total study duration is 18 months including 6 months for the recruitment and 12 months for the patients follow-up

Primary Outcome Measures:
  • Patient's acceptance of the disease evaluated by an analogical visual scale rating [ Time Frame: 12 months ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Glycaemic equilibrium by measuring the rate of glycosylated haemoglobin [ Time Frame: 12 months ] [ Designated as safety issue: No ]
  • Number of diabetic acidosis having required hospitalization, [ Time Frame: 12 months ] [ Designated as safety issue: No ]
  • Episodes number of severe hypoglycaemia having required an intervention of a third party or a hospitalization. [ Time Frame: 12 months ] [ Designated as safety issue: No ]
