Prevalence, awareness and control of hypertension in Uganda.

ABSTRACT:

Background

Prevention and control of hypertension are critical in reducing morbidity and mortality attributable to cardiovascular diseases. Awareness of hypertension is a pre-condition for control and prevention. This study estimated the proportion of adults who were hypertensive, were aware of their hypertension and those that achieved adequate control.

Methods

We conducted a community based cross sectional survey among people ≥ 15 years in Buikwe and Mukono districts of Uganda. People had their blood pressure measured and were interviewed about their social-demographic characteristics. Hypertension was defined as systolic blood pressure ≥ 140 mmHg, or diastolic blood pressure ≥ 90 mmHg, or previous diagnosis of hypertension. Participants were classified as hypertensive aware if they reported that they had previously been informed by a health professional that they had hypertension. Control of hypertension among those aware was if systolic blood pressure was <140 mmHg and diastolic blood pressure was <90 mmHg.

Results

The age standardized prevalence of hypertension was 27.2% (95% CI 25.9-28.5) similar among females (27.7%) and males (26.4%). Prevalence increased linearly with age, and age effect was more marked among females. Among the hypertensive participants, awareness was 28.2% (95% CI 25.4-31.0) higher among females (37.0%) compared to males (12.4%). Only 9.4% (95% CI 7.5-11.1) of all hypertensive participants were controlled. Control was higher among females (13.2%) compared to males (2.5%).

Conclusion

More than a quarter of the adult population had hypertension but awareness and control was very low. Measures are needed to enhance control, awareness and prevention of hypertension.

Project description:BackgroundThis study aimed to quantify prevalence, awareness, and control of hypertension in the Eastern Caribbean and identify sociodemographic correlates.MethodsBaseline data (2013-2018) from the Eastern Caribbean Health Outcomes Research Network Cohort Study (ECS) was used (n = 2961). The ECS is an ongoing longitudinal study of community-dwelling persons 40 years and older conducted in Barbados, Puerto Rico, Trinidad and Tobago, and U.S. Virgin Islands. Participants completed a self-administered health survey, clinical examination, and laboratory testing. The Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC-7) guidelines defined hypertension prevalence and control. Self-reported hypertension and clinical blood pressure values defined awareness. Binomial proportions, including 95% confidence intervals and logistic regression, were used for analyses.FindingsAnalyses included 2932 participants with complete data. The mean age of participants was 57 (SD = 10.3) years, and 65.3% (n = 1916/2932) were women. Prevalence of hypertension was 57.9% (n = 1698/2932), among whom 36.8% (n = 591/1698) were unaware, and 56.4 percent (n = 624/1107) of aware persons lacked control. Persons who were 70 and older (82.9%, n = 325/392, 95% CI:79.2%-86.6%), had low educational attainment (63.4%, n = 642/1012, 95% CI:60.5%-66.4%), obese (67.2%, n = 753/1121, 95% CI:64.4%-69.9%), and low physical activity (63.3%, n = 766/1210, 95% CI:60.6%-66.0%) had the highest prevalences of hypertension. Awareness was highest among persons 70 and older (76.6%, n = 249/325, 95% CI:72.0%-81.2%), women (70.7%, n = 781/1104, 95% CI:68.1%-73.4%), and those with a usual source of healthcare (70.4%, n = 1042/1480, 95% CI:68.1%-72.7%). Persons with lower educational attainment had lowest control across sociodemographic groups (36.1%, n = 154/427, 95% CI:31.5%-40.6%). Multivariable results showed ages 70 and older (OR = 10.6, 95% CI:7.4-15.2) and obesity (OR = 4.0, 95% CI:3.1-5.1) were the strongest predictors of hypertension. Usual source of care (OR = 5.66, 95% CI:3.8-8.4) and ages 70 and older (OR = 4.2, 95% CI:2.7-6.5) were most strongly associated with awareness. Results for control were not statistically significant.InterpretationFindings highlight challenges across the hypertension care cascade in the Eastern Caribbean, particularly with control. These findings have implications for public health and healthcare system solutions to improve screening and blood pressure control.FundingNational Heart, Lung, and Blood Institute Award--1K01HL145347-01A1, National Institute on Minority Health and Health Disparities (Yale-TCC)--U54MD010711, and National Institute on Minority Health and Health Disparities through the Eastern Caribbean Health Outcomes Research Network (ECHORN)--U24MD006939.
