The hypothesis of the research is that, thanks to a strategy of early detection of hypertension based on outreach by community relays, it will be possible to increase the effectiveness of primary prevention among the precarious population (early treatment, access to healthcare, improvement of therapeutic follow-up, reduction of renunciations and interruptions of treatment). This strategy, adapted to the Guianese context, would make it possible to reduce the incidence and mortality of cardiovascular diseases among the most vulnerable people, particularly stroke. Such data would be a prerequisite for a more ambitious strategy, aiming to implement policies on a sufficient scale policies on a scale and intensity sufficient to have an impact on the problem of social inequalities in health other than those related to high blood pressure.~The quasi-experimental before-and-after methodology makes it possible to compare, on a population basis, a quantitative endpoint - in this case the number of strokes - between before and after the implementation of a public health intervention. For reasons of acceptance by the partners, statistical power, and potential bias, a before-and-after design seems more interesting.~It will be a pre-screening of hypertension, a possible referral for medical care or opening of health care rights and health education through hygienic and dietary advice and health prevention focused on hypertension.
The main objective is to implement of a community-based primary care intervention against high blood pressure. We want to show that this intervention decreases the incidence of stroke in the community of agglomerations of the central coast of French Guiana, with a rapid effectiveness of about -30% at 2 years.
