Objectives. To identify the groups of patients with high prevalence and poor control of hypertension in South Africa.
Methods. In the first national Demographic and Health Survey, 12 952 randomly selected South Africans aged 15 years and older were surveyed. Trained interviewers completed
questionnaires on socio-demographic characteristics, lifestyle and the management of hypertension. This crosssectional survey included blood pressure, height and weight
measurements. Logistic regression analyses identified the determinants of hypertension and the treatment status.
Results. A high risk of hypertension was associated with less than tertiary education, older age groups, overweight and obese people, excess alcohol use, and a family history of
stroke and hypertension. Hypertension risk was lowest in rural blacks and significantly higher in obese black women than in women with a normal body mass index. Improved
hypertension control was found in the wealthy, women, older persons, Asians, and persons with medical insurance.
Conclusions. Rural black people had lower hypertension prevalence rates than the other groups. Poorer, younger men without health insurance had the worst level of hypertension
