A planned follow-up study on diabetes risk and aging in northern France

Populations in precarious situations or with low socio-economic status are at greater risk of diabetes and accelerated ageing. Depending on the population studied, the factors that may explain these health inequalities are not unequivocal and remain poorly understood.

Northern France, which is particularly affected by socio-economic disparities, has one of the highest diabetes prevalence rates in mainland France. This is why the researchers wanted to study the clinical, biological, social and behavioral risk factors for the onset of diabetes and accelerated aging in a large population in northern France.

A 2021 study aimed to characterize the population (a majority of whom (55%) suffer from precarious conditions) who came to the Institut Pasteur de Lille for their health check-up, in order to study risk factors to better explain these health inequalities.

This research consisted of a descriptive observational cross-sectional study carried out on 2233 volunteers (main group) over 18 months, and a complementary analytical case-control study involving 216 participants (sub-group).

At present, we are planning a 3-year follow-up of the cohort. Participants will be recontacted for a new health check-up at the Centre d'examen de Santé de l'Institut Pasteur de Lille. At the end of the health check-up, participants will be interviewed by PrévenDIAB study investigators to collect the same data as initially collected, with the exception of some data we deemed unnecessary.
