Uncontrolled hypertension in Uganda: A comparative cross-sectional study

In a community survey, 4432 persons aged 15 years and older in two districts in Uganda were studied. Blood pressure was measured and predictors for subtypes of uncontrolled hypertension (HTN) were assessed using bivariate and multivariate logistic regression modeling. Prevalence of uncontrolled HTN was 20.2% and the subgroups of isolated systolic HTN (ISH), isolated diastolic HTN (IDH), and systolic-diastolic HTN (SDH) were 7.2%, 4.2%, and 8.8%, respectively. No difference was observed between the sexes. For all HTN subtypes, middle (35-49 years) and older age (50+) groups had a higher prevalence compared with younger subjects (15-34 years) (all P<.001). IDH prevalence in older age was not higher compared with younger age (P =417). After multivariate analysis, middle age predicted all subtypes of HTN and old age predicted ISH and SDH. Alcohol consumption predicted IDH and SDH. Uncontrolled HTN in this population increases in the order IDH, ISH, and SDH, with more than 1 in 5 having uncontrolled HTN.
