Zusammenfassung:Abstract Background Individuals with SH have high 10-year risk of cardiovascular disease, especially when additional risk factors or target organ damage are present. Though some data from in-hospital or selected populations are available, there are no studies reporting community-level prevalence of Severe Hypertension (SH) in sub-Saharan Africa. Purpose Using a cross-sectional design in Abidjan (Ivory Coast), we assessed prevalence of Severe Hypertension among adults. Methods Study participants were recruited within the framework of The Heart Fund's global health initiative. Data were collected in August 2016 from 6 randomly selected sites, ensuring representativeness of both urban and rural areas. Blood pressure (BP) was measured twice, 10 minutes apart, after optimal resting time. Blood pressure measurement were standardized between sites and SH was defined as systolic blood pressure ≥180 and/or diastolic blood pressure ≥110 mmHg at both readings. Demographics and data on cardiovascular history/risk factors were collected in the field. Ethics approval for the study was obtained from the National Ethical Committee of Côte d'Ivoire and written informed consent was obtained from all adult patients. Results Among 1,785 subjects examined, 1,182 aged between 18 and 75 years were included in this analysis. The prevalence of SH was 14.1% (12.5% females vs 17.0% males; P=0.03) (Figure). Among participants with severe hypertension, 28.9% were either undiagnosed or untreated. Alarmingly, subjects at high cardiovascular risk (age ≥60 years and/or obese) had even higher prevalence of overall SH (29.6% and 24.9%, respectively) as well as undiagnosed/untreated SH (29.4% and 24.6%). SH prevalence was almost double in urban compared to rural areas (17.0% vs. 9.2%, P=0.02); however, conversely, undiagnosed/untreated SH was significantly higher in rural areas (50.4% vs 21.9%). Compared to normal bodyweight, those who were overweight and obese had a 1.95-fold (95% CI, 1.30–2.93; P
