DIABÉPI, a quantitative study on the relationship of people with diabetes to vaccination and their vulnerability to the COVID-19 epidemic


Participants who reported having poorly controlled diabetes and at least one other disease that could be considered a complication of diabetes were less supportive of vaccination than others.

There is a relationship between position in society (level of education, income, access to employment) and health. People with lower income and education levels are more likely to have poorer health.


The government’s vaccination strategy should pay special attention to people with low levels of education, income and access to employment. These are the people who would benefit most from COVID-19 vaccination and who are the least likely to be vaccinated.

Description of the Study:

  • Title: Étude DIABÉPI.
  • Principal Investigators: Pr Charles Thivolet, Jean-François Thébaut, Nicolas Naïditch, Gérard Raymond and Marguerite Cazeneuve.
  • Centers of Implementation: Société Francophone du Diabète, Fédération Française des Diabétiques, France Assos Santé and CNAM.
  • Study Population: Patients with diabetes.
  • Study Type: Quantitative study.
  • Methods: An online questionnaire was distributed in April 2021. It was constructed jointly with diabetics and with a scientific committee made up of several diabetologists, a public health physician, an ethicist, a methodologist and several members of the Fédération Française des Diabétiques. Statistical analyses were performed by the Diabetes Laboratory.

Objectives of the Study:

Principal Objective: To identify the profiles of diabetics according to their relationship with vaccination and a secondary objective was to know the reasons associated with their position.

More about this Study:

Although it has now been established that people with diabetes are no more likely than others to become infected with COVID-19, it appears that diabetes and the diseases most frequently associated with it (hypertension, obesity, heart failure, etc.) may lead to a more unfavorable course of the disease. In fact, the number of diabetics admitted to intensive care is two to three times higher than that of persons with other diseases and their risk of death is higher.

Although available scientific data indicate that vaccination against this virus reduces the risk of developing a severe form of the disease, some people with diabetes are hesitant or even opposed to vaccination.
