Key result
Self-reported hypertension affects ~19% of Ugandan adults, linked to older age, female sex, and tobacco.
Why the study?
Hypertension prevalence differs across regions and is increasing substantially in low- and middle-income countries, where it is modulated by lifestyle factors and poses cardiovascular disease risks.
Cross-Sectional (n=565)
No
Nearly one in five adults in rural central Uganda self-report having hypertension, highlighting a significant burden and the need for enhanced routine screening and health education.
Supports targeted awareness efforts among older women in rural Uganda; leaves open causal links and incidence pending prospective studies.
Background: The prevalence of hypertension (HTN) differs among regions and income groups, showing a substantial increase in low- and middle-income countries. The development of hypertension is modulated by modifiable lifestyle factors, and uncontrolled hypertension poses a risk for the onset of cardiovascular diseases. Objective: To determine the community-level point-prevalence and factors associated with self-reported HTN among adults in Butambala district, central Uganda. Methods: A community-based cross-sectional study was conducted among adults aged ≥18 years in Budde subcounty, central Uganda. Data on sociodemographic characteristics and behavior were collected using a semistructured questionnaire. Self-reported HTN was assessed using a single question: "Do you have high blood pressure?" Bivariate and multivariate logistic regression analyses were performed to identify predictors of self-reported HTN. Results: A total of 565 participants (53.5% female) with a median age of 38 years (IQR: 26-52) were included in the study. The prevalence of self-reported hypertension was 18.9%. Factors independently associated with HTN were age 60 years or older (aOR: 2.9, 95% CI: 1.64-5.23, p<0.001), female sex (aOR: 3.3, 95% CI: 2.3-6.3, p<0.001), being widowed (aOR: 10.4, 95% CI: 1.25-87.14, p=0.03), secondary (aOR: 0.4, 95% CI: 0.20-0.85, p=0.016) and tertiary (aOR: 0.2, 95% CI: 0.09-0.64, p=0.005) education, unemployment (aOR: 3.0, 95% CI: 1.11-7.96, p=0.03), tobacco use (aOR: 2.9, 95% CI: 1.83-4.53, p<0.001), having had at least one blood pressure measurement during antenatal visit (aOR: 4.7, 95% CI: 1.97-11.33, p<0.001) or medical checkup (aOR: 10.7, 95% CI: 6.06-18. Conclusion: We observed a high prevalence of self-reported HTN affecting approximately one in five participants. More efforts are required to enhance routine screening, health education, and accessibility to HTN services in rural areas, with a particular emphasis on implementing HTN prevention and control strategies to effectively reduce the prevalence of HTN.

Kato et al. (2023) conducted a cross-sectional in Hypertension (n=565). Sociodemographic and lifestyle factors vs. Reference groups was evaluated on Prevalence of self-reported hypertension. The community-level prevalence of self-reported hypertension among adults in central Uganda was 18.9%, with older age, female sex, and tobacco use identified as significant independent predictors.
