Résumé |
Background |
The prevalence of cardiovascular risk factors is increasing in sub-Saharan Africa.
Purpose |
To determine the prevalence of hypertension (HT) and other cardiovascular risk factors.
Methods |
this cross-sectional study was conducted in May 2017 at Brazzaville. This screening included subjects over 18 years old. Screening was carried out in 5 districts of Brazzaville. This activity (May Measurement Month) was initiated and supported by International Society of Hypertension (ISH).
Results |
A total of 3842 subjects were screened, including 2320 women (60.4%). The mean age was 47.6±15.8 years. The medical history were: excessive alcohol intake (13.7%), cigarette smoking (5.4%) and diabetes (5%). Of these, 954 were known HT and did not receive treatment (29.8%). Of these hypertensive patients, 409 (66%) were treated and uncontrolled. Mean BMI was 26±5.6, and abdominal obesity was noted in 823 (21.4%) cases. The mean systolic blood pressure (BP) was 134.5mmHg, 131.8mm Hg and 130.6mmHg respectively for the measurement 1, measurement 2 and measurement 3. The mean diastolic BP was 83.1mmHg for the measurement 1, 81.5mmHg for the measurement 2 and 80.7mmHg for the measurement 3. HT was noted in 1576 subjects (41%). After adjusting for sex and age, the change in systolic BP was dependent on antihypertensive drugs (P<0.0001), previous stroke (P=0.001), alcohol consumption (P=0.001), abdominal obesity (P<0.0001), overweight (P<0.0001) and obesity (P<0.0001). The change in diastolic BP depended on: antihypertensive drugs (P<0.0001), previous stroke (P=0.01), alcohol consumption (P<0.0001), abdominal obesity (P<0.0001), overweight (P=0.001) and obesity (P<0.0001).
Conclusion |
The prevalence of HT is high at Brazzaville. Known hypertensive patients are little treated, and they are poorly controlled. Therefore, nationwide screening is needed to increase awareness and prevent complications.
