[Arterial hypertension in Dakar: Prevalence, awareness, treatment, and control].

The aim of this study was to determine prevalence, awareness, treatment, and control of hypertension, and its risk factors in Dakar. Six hundred people aged 20 and older, living in the city of Dakar were interviewed. This sample was constructed using the combined quota method in order to strive to representativeness of the target population. Prevalence of hypertension was 27.50%. Quarter of those suffering from high blood pressure were aware of their problem, and among the latter, 61% said they were on treatment. However, of these, only 32% had controlled arterial blood pressure, that is less than 6% of those suffering from hypertension. Two factors were associated with hypertension, awareness, and treatment: age and the frequency of doctor visits. These results indicate that hypertension already constitutes a major health concern in the Senegalese capital. Detection can be considerably improved given that only a quarter of the hypertensives are aware of this problem. Compliance with treatments also appears particularly problematic. Public health policies should be quickly set up to minimize the consequences of this emerging burden.
