Prevalence of hypertension in the South African Demographic Health Survey (DHS) in 2016 was 48.2%, with crude prevalence estimated between 6-18% across the 9 provinces (Kandala, et al., 2021). About 46% of women and 44% of men have hypertension (systolic blood pressure above 140mmHg), rising with age and most common among white, followed by coloured men and women (StatsSA, 2017b).
