The lipid and lipoprotein profile of the urban black South Africa population of the Cape Peninsula - the BRISK study.

Abstract

The total cholesterol (TC level) was low compared with other South African groups studied. Men had a mean TC of 3.98 mmol/l and women 4.15 mmol/l. Low-density lipoprotein cholesterol (LDLC) values for men (2.03 mmol/l) were lower than those for women (2.30 mmol/l). Men (1.35 mmol/l) and women (1.37 mmol/l) had similar high-density lipoprotein cholesterol (HDLC) levels. Both sexes had a prevalence of protective HDL/TC ratios above 30% for all age groups. High HDL3C levels and low HDL2C levels were found in both men and women. Apolipoprotein A and B followed the trends of HDLC and LDLC and showed no difference between the sexes. The plasma triglyceride (TG) levels increased with age in both sexes. Men displayed higher TG levels than women in all age groups. Seventeen per cent of men and 26% of women had a moderate-to-high risk for CHD, given their TC levels. Other lipid-related risk factors indicated low risk for CHD.
