The Entred 3 study aims to meet the information needs of funding agencies and healthcare professionals working in the field of diabetes.

The main objectives of the Entred 3 study are as follows:

To describe and study trends in:

• in the characteristics of people with diabetes receiving pharmacological treatment, particularly their socioeconomic status;

• in diabetes-related health status;

• the cost of care;

• the care pathway, including educational initiatives;

• use of care and adherence to treatment;

• the quality of care;

• cause-specific mortality.

Expand research on the specific characteristics of certain populations:

• people with type 1 diabetes, for whom little information is currently available;

• people with diabetes living in French overseas territories (French Guiana, Réunion, Martinique, Guadeloupe). In these departments, diabetes is more common than in mainland France, and the incidence of complications is also higher.

Make baseline data available to the scientific community and health programs to enable comparative analyses for evaluation purposes.

Describe:

• the quality of life of people with diabetes;

• the knowledge, perceptions, and behaviors of people with diabetes (dietary habits, physical activity);

• the resources used by patients, particularly in therapeutic education, and recommended by physicians;

• the use of new devices and connected tools;

• acute complications: hypoglycemia and use of healthcare services;

• therapeutic strategies and new antidiabetic medications;

• the impact of diabetes on professional, family, and social life;

• health ^literacy¹: “Health literacy is the motivation and ability of individuals to access, understand, evaluate, and use information to make decisions regarding their health.”

The Entred studies conducted in 2001 and 2007 provided data on epidemiology, medicine, economics, social factors, and the quality of care (including educational initiatives).

This information is crucial for developing prevention initiatives aimed at improving medical practices and enhancing the health status and quality of life of people with diabetes.

For example, previous Entred studies highlighted a significant improvement in the management of vascular risk factors for people with type 2 diabetes between 2001 and 2007^¹. These studies also showed that certain screening and treatment of diabetes complications, particularly ophthalmological, podiatric, or renal complications, should be improved².

Finally, the 2007 Entred study revealed that the lower the socioeconomic status of people with diabetes, the higher the prevalence of certain risk factors (obesity, smoking, poor glycemic control) and certain complications (coronary and podiatric)³.

The results of the Entred 3 study will be compared with those from 2007 and 2001. It will once again be possible to highlight the progress made, as well as the progress still needed to better care for people with diabetes and prevent the onset of complications. This new study will also allow for the exploration of new topics, such as health literacy, healthcare utilization, and treatment adherence.

This study focuses on individuals covered by Medicare or the Social Security system for the self-employed, aged 18 or older, who are receiving medication for diabetes.

A random sample of 13,000 people with diabetes:

• 9,000 people with diabetes in mainland France;

• 4,000 people with diabetes in the French overseas departments (Guadeloupe, French Guiana, Martinique, and Réunion).
