Oral Glucose Tolerance Test and Post Partum Diagnosis of Diabetes Mellitus, Type 2 (DT2 Post-Partum)

Study Overview
=================
Brief Summary
-----------------
Diabetes mellitus, type 2, is a chronic disease which can be linked with many complications in connexion with impaired blood glucose balance. It diagnosis in risky subjects such as in patients with medical history of gestational diabetes is therefore imperative to prevent its complications. Actual guidelines recommend an oral tolerance glucose test, measuring glucose levels after oral glucose intake (75g), between 6 an 12 weeks after childbirth. But studies reveal a low diagnosis rate. The study of the current practices of diagnosis methods seem to be essential in order to improve this diagnosis.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Women with medical history of gestational diabetes<br>Patients followed at the hospital of Vienne for gestational diabetes in 2016. | Other: frequency of diabetes mellitus, type 2, diagnosis in patients with medical history of gestational diabetes.<br>* Patients will be contacted by mail with sending of the information notice to ask them to participate in the study. If they don't reply, the subjects will be called by phone by the investigator to collect their non opposition of participation at the study. During this call, the investigator will be able to answer all the questions about the study. The report of this telephone conversation will be register in the medical file of the patient. Then, we will collect informatic data from the hospital concerning the patients. After that they will be contacted by phone to answer a survey. Beside, another secure survey will be send by email to each patient's family doctor. To finish, crossing data between those of the patients and the family doctor and anonymisation of the data.<br>* Other names: Evaluate the frequency of diabetes mellitus, type 2, diagnosis with an oral glucose tolerance test between 6 and 12 weeks after childbirth in patients with medical history of gestational diabetes.;|
