Knowledge, Attitudes, Practices and Blood Pressure Control of Hypertensive Patients at a South African Primary Health Care Centre

Hypertension is a serious global and South African public health problem. The high prevalence of uncontrolled hypertension is related to a patient’s lack of knowledge and healthy practices. The study aimed to assess the knowledge, attitudes and practices of hypertensive patients and their blood pressure control at a rural community health centre. This was a prospective cross-sectional study conducted on diagnosed cases of hypertension at the centre. Binary logistic regression analysis was conducted to determine the factors for the control of hypertension. Two hundred and ninety-seven known hypertensive patients were recruited, the majority of which were female. Eighty-eight percent were older than 45 years, and almost all had a monthly income of less than R3000 (USD 190). More than half controlled their blood pressure. It was found that 46% had poor knowledge, 64% had good attitudes and 60% were practising positively regarding the control of hypertension. Hypertensive patients attending the centre had poor knowledge but good attitudes and practices towards hypertension. The study revealed an urgent need for improved health promotion and educational efforts to increase the knowledge of hypertension in rural communities and to address poverty as a major obstacle to healthy lifestyle choices.
