Hypercholesterolemia in diabetes in Dakar. Sociodemographic and etiological factors and therapeutic bases

This study took place between January and September 1996. The inclusion criteria was a blood cholesterol concentration of at least 2.5 g/l. Thirty-three patients were included. They were aged from 37 to 77 years, with a mean age of 59 (+/- 9.4) years. Twenty-six were women and seven were men. The mean age of the women was 58.9 (+/- 10) years and that of the men was 61 (+/- 6.1) years. Sixteen patients were from urban areas, 14 from semi-rural areas and 3 were of rural origin. The mean duration of diabetes was 9 (+/- 6.5) years. Mean post-prandial blood glucose concentration was 2.2 (+/- 1.0) g/l. Mean body mass index was 25.6 (+/- 5.6). Mean systolic blood pressure was 15.0 (+/- 2.5) cm Hg and mean diastolic blood pressure was 9.0 (+/- 1.3) mm Hg. Blood cholesterol concentration was between 2.5 g/l and 5.6 g/l, and mean HDL cholesterol concentration was 0.7 (+/- 0.4) g/l. Mean blood triglyceride concentration was 1.0 (+/- 0.4) g/l. Body mass index was negatively correlated with high cholesterol levels (r = -0.29). Hypercholesterolemia was primary, with no associated high triglyceride concentration. Cholesterol levels were also negatively correlated with post-prandial blood glucose concentration (r = -0.1). Thus, treatment should involve the prescription of drugs to reduce blood lipid concentration rather than just the restriction of lipid intake.
