Burden of Hypertension

In 2011, hypertension was a significant public health issue in the United Republic of Tanzania (Zanzibar). The estimated prevalence among adults was approximately 31.2%, with about 129,500 individuals affected out of a total population of around 1.3 million. Awareness was low, with less than 10% of those with hypertension diagnosing themselves, while only a small fraction, around 1.6%, were under treatment and had controlled blood pressure.

awareness rate based on available data showing 9.7k aware individuals out of 129.5k with hypertension, equating to roughly 7.5% at diagnosis.

Management Status

Only about 1.6% of the hypertensive population was under treatment, and control rates were extremely low, with only a fraction (approximately 0.3k) achieving controlled blood pressure. Age and sex analyses revealed variations, but overall, hypertension management was inadequate.

National Context and WHO Recommendations

• National systems response from 2019 lacked data on essential hypertension policies, salt consumption, and medical availability, indicating gaps in healthcare infrastructure.
• There were no available national targets for raised blood pressure or salt consumption.

WHO recommended addressing modifiable risk factors like high salt intake and improving hypertension detection, treatment, and control through technical packages, along with tracking rates. Data on trends in uncontrolled hypertension were not available.

Recommendations and Gaps

WHO emphasized using its technical initiatives for prevention and control, but the data highlighted poor awareness and treatment rates. No progress was noted since the 2011 survey, with ongoing issues in national system response.
