>Magister Scientiae - MSc / The burden of non-communicable diseases (NCDs) in South Africa is predicted to increase substantially in the next decades if the necessary preventative measures are not taken. The two most common NCDs associated with rapid mortality increase are diabetes mellitus (DM) and hypertension (HTN). Both of these diseases, i.e DM and HTN, can be a result of a combination of modifiable risk factors (behavioral) and non-modifiable risk factors (genetic, physiological, and environmental). New strategies implemented to manage these diseases should include addressing both modifiable and non-modifiable risk factors for patients with NCDs. The aim of this study was to contribute to the reduction of incidence of uncontrolled T2DM among patients taking metformin as a first-line anti-diabetic drug, through the development of individualized therapy for this drug. When implemented, this could be one of the healthcare strategies to address non-modifiable risk factors for patients with T2DM as an important NCD. The first objective of the study was to explore the prevalence and risk factors of DM and HTN in South Africa, especially within the economically disadvantaged population.
