Insights
In Cameroon, only 36.8% of hypertension patients achieved controlled blood pressure. Good adherence to medication and lifestyle changes are key predictors for effective blood pressure management.
Area of Science:
- Cardiology
- Public Health
- Epidemiology
Background:
- Hypertension significantly contributes to morbidity and mortality globally.
- Understanding patient characteristics and treatment factors is crucial for improving hypertension management and reducing cardiovascular risks.
- Limited data exists on factors influencing blood pressure control in Cameroon.
Purpose of the Study:
- To determine the predictors of blood pressure control among hypertensive patients in an urban setting in Cameroon.
Main Methods:
- A descriptive cross-sectional study was conducted in five outpatient hypertension clinics in Yaoundé, Cameroon.
- Controlled hypertension was defined as blood pressure ≤140/90 mmHg.
- Logistic regression analysis was employed to identify factors associated with blood pressure control.
Main Results:
- Out of 440 patients, 63.6% were female, with a mean age of 61 years.
- Only 36.8% of patients achieved controlled blood pressure (BP ≤140/90 mmHg).
- Good adherence to anti-hypertensive medications (OR=3.99) and dietary lifestyle changes (OR=1.5) were independently associated with controlled hypertension.
Conclusions:
- A significant proportion of hypertensive patients in Yaoundé have uncontrolled blood pressure.
- Adherence to treatment and lifestyle modifications are vital for achieving optimal blood pressure control in primary care settings.
- Targeted interventions for patients at risk of non-adherence are needed to reduce hypertension-related morbidity and mortality.
Background:
Hypertension is associated with considerable morbidity and mortality. Improvement of its management to reduce adverse cardiovascular outcomes will require an understanding of the patient characteristics and treatment factors associated with uncontrolled blood pressure. Factors that affect blood pressure control have not been sufficiently described in Cameroon. The main goal of our study was to determine the predictors of blood pressure control in patients with hypertension in an urban city in Cameroon.
Methods:
This was descriptive cross-sectional study from five outpatient hypertension consultation units in Hospitals in Yaoundé. Controlled hypertension was defined as blood pressure ≤140/90 mmHg. Logistic regression was used to determine factors associated with blood pressure control.
Results:
Among the 440 patients enrolled in the survey, 280 (63.6%) were females. The mean age was 61 (SD ±11) years. Mean systolic blood pressure (SBP) was 147 mmHg and mean diastolic blood pressure (DBP) was 88 mmHg. Only 36.8% of patients had their mean blood pressure controlled (BP ≤140/90 mmHg). Multivariable logistic regression analysis revealed good adherence to anti-hypertensive medications (OR= 3.99; 95% CI: 2.20-7.23; P<0.000) and dietary lifestyle changes (OR =1.5; 95% CI: 0.53-2.49; P=0.031) to be factors independently associated with controlled hypertension.
Conclusions:
Only one out of three patients has their blood pressure controlled. The results of our study suggest that good adherence to treatment are important factors for tight blood pressure control in primary care. Further identification of patients at risk of non-adherence to treatment and poor blood pressure control can lead to targeted interventions to reduce hypertension related morbidity and mortality in this setting.

Hypertension and Regulation of Blood Pressure
Blood Pressure
The average BP in an adult is typically around 120/80 mmHg (millimeters of mercury). In this measurement, the numerator (120) indicates the systolic pressure, which is the pressure in the arteries during the contraction of the heart's ventricles as blood is expelled. The denominator (80) represents the...

Special considerations while measuring blood pressure
Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.
