Prevalence of dyslipidaemia among type 2 diabetes mellitus patients in the Western Cape, South Africa

Abstract

Dyslipidaemia, an irregular aggregate of lipids in the blood is common in diabetes and cardiovascular disease sufferers. A cross-sectional study on the prevalence of dyslipidaemia was performed among type 2 diabetes mellitus (T2DM) patients in the Western Cape, South Africa. Patients (n = 100) that participated in the study were within the age range of 19–68 years, of whom 89% were observed to have serum lipid abnormalities. Out of the 100 patients, 56%, 64%, 61%, and 65% were recorded to have high total cholesterol (TC), hypertriglycemia, increased low-density lipoproteins cholesterol (LDL-C), and reduced high-density lipoproteins cholesterol (HDL-C), respectively. In male diabetic patients, a marked prevalence of (94%) dyslipidemia was noted, of which 52% were affected by high TC (5.3–7.9 mmol/L), with 70% having a high level of triglyceride (TG) [1.72–7.34 mmol/L], while 60% had a high LDL-C (3.1–5.5 mmol/L), including 78% with low HDL-C (0.7–1.1 mmol/L). In comparison, 84% of diabetic females had dyslipidemia, with high TC (5.1–8.1 mmol/L), hypertriglycemia (1.73–8.63 mmol/L), high LDL-C (3.1–5.6 mmol/L), and low levels of HDL-C (0.8–1.1 mmol/L) affecting 60%, 58%, 62%, and 52% of the patients, respectively. This study showed the importance of screening and the regular surveillance of dyslipidaemia in T2DM patients as there is a paucity of data on it in Africa
