Regional epidemiological data on diabetes

Prevalence of Diabetes by Region

In 2013, the prevalence of treated diabetes was higher in the overseas departments, where it was up to twice as high as the national average. It was also higher in certain regions of mainland France, particularly in the North and Northeast, and in certain departments of the Île-de-France region, but it was lower in Brittany.

Incidence of diabetes-related complications by region

In 2013, in France, the incidence rates of hospitalizations for diabetes-related cardiovascular and podiatric complications varied significantly by region. Some regions, such as Limousin, had very high rates of people hospitalized for myocardial infarction (MI) compared to the national rate. Conversely, the overseas departments (with the exception of Guadeloupe) were characterized by lower rates of MI but higher rates of stroke. Hospitalization rates for lower limb amputation were very high in the overseas departments.

Adherence to Recommended Screenings by Region

Follow-up on recommended screenings varied by region. French Guiana and Limousin stood out from other regions with relatively low follow-up rates compared to national averages. Conversely, Réunion recorded better follow-up for most indicators.

Diabetes in the Overseas Departments and Territories

The overseas departments (DOM) component of the 2007 Entred study examined the characteristics and health status of people with diabetes receiving treatment, as well as diabetes care in Guadeloupe and Martinique, French Guiana, and Réunion. The diabetic population in the overseas departments was younger than in mainland France (63 years vs. 65 years), predominantly female (65% women vs. 46%), and economically more disadvantaged than in mainland France. Type 2 diabetes was the most common form (96%). The vascular risk among people with type 2 diabetes was high, but obesity was less common than in mainland France. Diabetes was difficult to control, and insulin therapy was more common than in mainland France, although the average HbA1c level was higher there (7.4% vs. 7.1%). The profile of type 2 diabetes complications differed between the French overseas departments and mainland France; coronary complications and foot complications were less common there, whereas ophthalmological complications were more common. The quality of type 2 diabetes care was very similar to that in mainland France, and in some cases better.

Other specific studies have been conducted in the overseas departments and communities:

  • Escal, conducted in 2003–2004 and analyzed by the Antilles-Guyana Interregional Epidemiology Unit (Cire) in Martinique,

  • Maydia, conducted by the Indian Ocean Cire in Mayotte in 2008,

  • Redia, on Réunion Island, conducted by the Center for Clinical Investigation and Clinical Epidemiology of Réunion with support from the French Institute for Public Health Surveillance (InVS).
