Study of Diabetes' Risk Factors and Accelerated Aging According to Socio-economic Status in a Population From the North of France - 3-year Follow-up

Primary Objective : To measure changes in fasting glycemic control after 3 years in PrevenDIAB-1 study participants according to socioeconomic status Primary efficacy endpoint : fasting plasma glucose and Hb1Ac * Conversion rate of glycemic status (worsening, stable, improving) according to EPICES score * Prevalence of pre-diabetes/diabetes (T0 and T 3 years) according to EPICES score Secondary objectivesspecific to the main group : * Observe the evolution of anthropometric factors such as BMI (weight), waist circumference and various measures of body composition, and determine their role in the evolution of glycemia. * Observe the evolution of clinical, biological, metabolomic, behavioral and environmental factors, and determine their role in the evolution of glycemia. * Measure the impact of PrevenDIAB-1 (+/- prevention intervention) on changes in behaviour and health perception according to socio-economic status (has the completion of a health check-up enabled people to resume a course of care and/or raise awareness/engage in prevention?) * Gather information on subjects' possible participation in preventive actions, define them (type, duration, indication, etc.) and assess their potential impact on risk factors. * Propose a personalized care pathway for different risk profiles (roadmap defined for people with diabetes or morbid obesity, for example), create a city-hospital link and follow up with subjects by telephone at 6 months to obtain their feedback/opinions on the management of their pathology. Secondary Objectives specific to the sub-group: * Measure changes in the following subgroup parameters: * physical activity * sleep * alcohol consumption * frailty * arterial stiffness * cognitive status * Determine the link with pre-diabetes and diabetes. * Obtain qualitative data by setting up focus groups on the co-creation of a "space of trust" promoting health empowerment. * This work will be carried out by a "health and human sciences" post-doc in 2025.
