Objective: In France, there are 17 million hypertensive (25.5% of the population) and 3.6 million diabetics (5.4% of the population). This prevalence is higher in precarious populations such as those in Seine-Saint-Denis. In response to these findings, the Bobigny-Bondy CPTS, in collaboration with our ESH center, has set up a 7-stage screening program (one of which incorporates MMM protocol adapted in French by the French Society of Hypertension (SFHTA)) for these two chronic diseases. The aim of our study is to disseminate data obtained from a sample of adults in Seine-Saint-Denis during joint ’Hypertension and diabetes’ screening actions in 2023. Design and method: Seven stages of action with our population were carried out (reception, biometry, nurse interview, dietetic interview, associative interview, medical interview) (1. Diagram). The MMM protocol, adapted in French by the SFHTA, was also proposed to each participant. Results: General anonymous data for this population of 469 subjects (including 275 F) are summarize in Table (2). In this population, 38.6% declared hypertension. Of the non-hypertensive sample (n=279), 24.4% of participants presented with averages above 140/90 mmHg and 10.4% with grade 2 hypertension. As for diabetes, 18.8% of the sample claimed to be diabetic, and 8.3% of fasting participants presented with blood glucose levels suggestive of diabetes. This joint city/hospital screening program, initiated by a CPTS, confirms the high prevalence of these pathologies in our population, with more than half the participants screened concerned with hypertension and more than a quarter concerned with diabetes. Conclusions: Developing prevention and screening actions according to the needs of a population is a priority mission for CPTSs. In the case of hypertension, the MMM kit proposed by the SFHTA has helped to establish part of the framework for action. Ministerial health authorities will need to provide more resources to encourage screening not only for diabetes, but also for frequent cardiovascular diseases such as hypertension, since their association can be ’explosive’, as in the case of COVID.
