Prevalence, awareness and factors associated with hypertension among
adults in rural south-western Uganda: a baseline survey
Abstract
Background: Hypertension is the leading cause of preventable
deaths globally, yet reports on its burden and risk factors in rural
Sub-Saharan Africa have been inconsistent. This study aimed to assess
the prevalence, awareness, and factors associated with hypertension
among adults in a rural community in southwestern Uganda.
Methods: A baseline survey was conducted in Ngango, Mbarara
district, involving adults aged 18-79 from eleven villages. Research
assistants and community health workers enrolled consenting participants
from their homes using the WHO STEPS questionnaire, gathering
demographic, behavioral characteristics (e.g., tobacco and alcohol use),
and lifestyle factors including dietary habits and physical activity.
Blood pressure (BP) readings were taken three times. Hypertension was
defined as BP ≥140/90 mmHg or self-reported use of antihypertensive
medication. We used logistic regression to identify factors associated
with hypertension. Results: A total of 953 adults were
enrolled, with a median (IQR) age of 43 (30-57) years, 61.5% female and
only 43.5% recalled ever having a BP measure. The prevalence of
hypertension was found to be 27.3% with 61.5% unaware of their
condition. Only 27.7% receiving treatment and 65.3% had controlled BP.
Despite 66.8% reporting good physical activity, 63.7% were overweight.
Key factors associated with hypertension included being over 40 years
old (OR 2.26), consuming fewer than three servings of fruits or
vegetables weekly (OR 1.62), and being overweight or obese (OR 1.57 and
OR 2.73, respectively). Conclusion: The prevalence of
hypertension in rural southwestern Uganda is high, highlighting the need
for targeted interventions, particularly in a relatively young and
physically active population
