Background
Despite the availability of effective low-cost treatments, systemic hypertension continues to be a major cause of cardiovascular morbidity and premature death particularly in low resource countries where the overall prevalence of hypertension is increasing.
Methods
We estimated the prevalence, level of awareness and hypertension control in individuals the Human Hereditary and Health in Africa Kidney Disease Study (H3A-KDRN) in West Africa (n=8392). Using a standardized protocol, trained study staff measured three blood pressure in participants. We defined hypertension as systolic blood pressure ≥140 mmHg and/or diastolic blood pressure ≥90mmHg and/or self-reported antihypertensive medication use. We defined awareness of hypertension was defined using self-report and hypertension control as blood pressure <140/90mmHg.
Results
The prevalence of hypertension in the entire cohort was 53.7%. Of those with hypertension, 70.4% were aware of their diagnosis of hypertension, 54% were on medication on medication while 32.3% had controlled blood pressure to <140/90mmHg. Older individuals, those with lower eGFR, Ghanaians compared to Nigerians, obese individuals and alcohol drinkers were more likely to be aware of their hypertension diagnosis. Older age individuals, those with lower eGFR, and Ghanaians were all less likely to have a controlled blood pressure.
Conclusion
Despite the moderate level of awareness of hypertension in this cohort, the rate of hypertension control was suboptimal. There is need for programs to ensure for reliable and affordable access to the treatment of hypertension in Africa.
