Background Results Table 2. Sociodemographic and clinical characteristics associated with untreated HTN treatment among
• Globally, 1.39 billion individuals have hypertensive individuals
hypertension, with a prevalence of 31.1%.
• In Sub-Sharan Africa, South Africa has the
heaviest burden of disease with an 35% 28%
estimated prevalence between 27-58%.
• Despite acknowledging HTN as the most 10%
common life-threatening risk factor for 27%
CVD, dearth of data is available on the
prevalence, awareness and determinants
of HTN in rural parts of South Africa.
Aim NORMAL ELEVATED
• To assess the prevalence and associated HYPERTENSION GRADE 1 HYPERTENSION GRADE II
risk factors among black African population
of Mthatha town, Eastern Cape. Figure 1. Distribution of participants according to their blood pressure
Table 1. Multivariable logistic regression model of sociodemographic
and clinical factors associated with HTN.
Methods

• Variables such as gender, age, race, body mass index (BMI), blood glucose levels,
marital status, level of education, monthly income, status of employment, physical
activity, diet pattern, beliefs of HTN and its treatment were screened but only those
displayed in Table 1 showed significant association with HTN in a multivariate logistic
regression model.
• Table 2 describes potential factors that were associated with untreated HTN among
hypertensive individuals.
Discussion and Conclusion
• Prevalence of HTN was high among the black African population of Mthatha town.
• Sex, age, western diet, diabetic and overweight/obese status were the most significant
predictors of HTN.
• Male sex and participants who does not value the use of medication for the treatment
of HTN were associated with higher odds of being untreated.
• Being female, aged and overweight/obese reduces the risks of being untreated.
