Study Description

Brief Summary:

The main objective of the study is to follow prospectively a cohort of patients with pre-diabetes to understand the pathophysiological mechanisms involved in switching from pre-diabetes to type 2 diabetes and to identify new biomarkers of type 2 diabetes risk in this population.

Arms and Interventions

Intervention Details:

• Other: Pre-diabetes screening
  The timing of the study is :- Screening of high metabolic risk patients based on a clinical score : Finnish Diabetes Risk Score ≥ 15- if Diabetes Risk Score ≥ 15 or if history of blood glucose between 1.10 and 1.26 g/l (impaired fasting glucose): measuring fasting glycaemia + HbA1C + lipids profile + creatinemia + liver enzymes- if fasting blood glucose between 1.10 and 1.26 g/l (=V0):* OGTT (oral glucose tolerance test) to identify subjects with impaired glucose tolerance (optional)* establishment of a serum bank to identify biomarkers (serum, genomic, proteomic) - to plan for 10 years annual follow-up (V1 to V10) with blood sample (fasting glycemia + HbA1C + lipids profile + creatinemia + liver enzymes + serum bank (not after V5)) Making a total of 11 visits (V0-V10) with 6 blood samples.

Outcome Measures

Primary Outcome Measures :

1. The main objective of the study is to understand the pathophysiological mechanisms involved in switching from pre-diabetes to type 2 diabetes and to identify new biomarkers of type 2 diabetes risk in this population [ Time Frame: 10 years ]
   The main objective of the study is to follow prospectively a cohort of patients with pre-diabetes to understand the pathophysiological mechanisms involved in switching from pre-diabetes to type 2 diabetes and to identify new biomarkers of type 2 diabetes risk in this population

Secondary Outcome Measures :

1. Number of patients with pre-diabetes [ Time Frame: 10 years ]
   To evaluate the prevalence of pre-diabetes in the region of Nantes
2. HbA1c measurement [ Time Frame: 10 years ]
   To evaluate the role of HbA1C in screening for pre-diabetes and T2D
3. Number of patients with high Diabetes Risk Score and pre-diabetes [ Time Frame: 10 years ]
   To evaluate the interest of the Diabetes Risk Score in identifying subjects with pre-diabetes in the French population
4. Number of patients with others cardiovascular risk factors [ Time Frame: 10 years ]
   To evaluate the prevalence of others cardiovascular risk factors associated with pre-diabetes: dyslipidemia, hypertension, metabolic liver disease
5. Relation between "working hours and conditions" and metabolic disease [ Time Frame: 10 years ]
   To evaluate the impact of working hours and conditions on the prevalence of metabolic diseases (pre-diabetes, dyslipidemia…)
