Population

7,116 participants aged 15-64 years residing in Rwanda, mean age 35.3 years, 62.8% female.

Outcome

Prevalence of hypertension (defined as systolic blood pressure >= 140 mmHg and/or diastolic blood pressure >= 90 mmHg or currently taking antihypertensive medications)

Hypertension is highly prevalent (15.4%) but poorly diagnosed in Rwanda, with age, obesity, alcohol consumption, and semi-urban residence identified as key risk factors.

Limitations

Cross-sectional survey design limits the ability to infer causation between risk factors and hypertension.
Prevalence may have been over or under-estimated because blood pressure measurements were performed on one occasion only.
Unable to explore the contribution of other risk factors such as unhealthy diet, salt intake, and psychosocial stress.
Cross-sectional survey design limits causal inference between risk factors and hypertension.
Blood pressure measurements were performed on one occasion only, which may over- or under-estimate prevalence.
Unable to explore the contribution of other risk factors such as unhealthy diet, salt intake, and psychosocial stress due to lack of data collection.
