Summary
Cardiovascular disease, particularly high blood pressure (hypertension), is a significant health burden in Ghana. Urban populations and older adults face higher hypertension rates, with many unaware of or undertreated for their condition.
Area of Science:
- Cardiology
- Public Health
- Epidemiology
Background:
- Cardiovascular diseases (CVDs) represent a growing health concern in Africa.
- Noncommunicable diseases (NCDs) often receive less focus than communicable diseases in African health budgets.
- Understanding hypertension prevalence is crucial for public health planning in Ghana.
Purpose of the Study:
- To evaluate the health burden of cardiovascular diseases, specifically hypertension, in urban and rural Ghanaian communities.
- To identify demographic and lifestyle factors associated with hypertension in the study population.
Main Methods:
- Longitudinal study conducted in Ghana from 1972 to 1987.
- Inclusion of adult residents from both urban and rural areas.
- Analysis of hypertension prevalence, awareness, treatment, and associated determinants.
Main Results:
- Hypertension prevalence was higher in urban adults (8-13%) compared to rural adults (4.5%).
- Prevalence increased significantly with age (29% for ≥35 years vs. 3.9% for <35 years).
- Awareness and adequate treatment rates for hypertension were low among diagnosed individuals.
Conclusions:
- Hypertension poses a substantial health burden in Ghana, with significant urban-rural and age-related disparities.
- Limited awareness and inadequate treatment highlight the need for improved hypertension management strategies.
- This study underscores the importance of addressing NCDs in African health research and policy.
