In 2010, the number of children with type 1 diabetes in France is estimated at 12,000 with 60% of them aged 12 to 17 years. Compliance is a major issue during adolescence. Mobile text message is one of the strategies to enhance adherence. The main aim of this study is to assess HbA1c reduction after a 6 month SMS support among adolescents with poorly controlled type 1 diabetes. Adherence and quality of life will also be assessed at the end of the trial. This study is a prospective randomized monocentric trial. Sixty adolescents with type 1 diabetes and HbA1c equal or higher than 8.5 % will be randomized according to the method of Zelen in two groups : standard treatment versus standard treatment plus support by SMS. The patients will receive one SMS before each injection of insulin.
The purpose of this study is to assess HbA1c reduction after supportive care by SMS among adolescents with poorly controlled type 1 diabetes.
